The Baptist Church of Streetsboro, Ohio, Part 1



This is the Old Baptist Church at Streetsboro, Ohio, built about 1820.




Here are the HABS drawings.


 I wondered about its geometry. What framing traditions had the master builder brought with him to Ohio?
It looked linear, simple, obvious. Was it?



I explored the plan and elevation. While many forms of the Lines created by circles and squares worked pretty well, nothing quite fit.  
I went back to the basics, the construction: What did the carpenter do? In what order?


He was asked to build a church about 'so big'  - here about 36' x 50'. He laid out a rectangle using the 3/4/5 Triangle.  The HABS drawings are blurry and tiny. The dimensions appear to be 38'-4.5" wide by 51' long,  3 units wide by 4 units long. (The length is about an inch too short.)

The triangles are ABC and ADC. They could also be ABD and BCD. The 2 layouts cross in the center.
The carpenter could check his diagonals, just as workers do today. When the diagonals were the same length the floor frame was square.




 The bents for the frame were naturally the same width as the floor. It seemed possible that the framer used the floor of the church for his layout. I had seen this in an upstate NY barn. I wrote about it here: https://blog.greenmountaintimberframes.com/2014/12/04/geometry-in-historical-frames-a-guest-blog/

The elevation of the front of the church appears to be 2 squares wide. But the pediment did not come easily from that form - slightly too big.

However when I laid out the frame based on Lines laid on the inside edge of the sill and posts, everything fit and the peak of the bent, the location of the ridge of the church was the center of the rectangle. So simple, so easy!


How was it to the framer's advantage to lay out the frame from within the frame, not outside?  
He needed at least 3 bents, probably 5 or more. He needed consistent marks for lengths and widths of all members and for each mortise and tenon. The Lines laid inside the frame would not be disturbed while the frame was laid out and marked. The timbers could be moved off the floor to cut the joints; another bent could be laid out.  Or the bents could be stacked on each other.
Modern framers using timber and dimensional lumber stand within their work, measure, mark, and check from inside. Then they cut the lumber someplace else. Why not this earlier framer too?




After the bents and the roof trusses came the walls and the windows.
The spacing of the windows and their width comes from the rectangles that are within the original larger rectangle.
The green lines are 2 of those rectangles, the dashed lines with arrows on the left show the window frame locations.  The green dashed line with an arrow on the right ( top left) is the width. 



  



The geometry of the bents determined the shape of the facade, the height of the pediment. The front elements of the church - the  pilasters and a grand door -  were designed after the frame. The front windows were in place, therefore the pilasters needed to be equidistant on each side.
The door went in the middle, that's custom. Then there was the left over space in between. (See more about this below.)



The framers also had to provide support for the steeple. I have only photographs to show where the steeple sits. Was it directly over the front wall? a few feet back?  I would assume a bent supported the front and back walls of the steeple. The diagrams do show how the width of the tower and the size of the clipped corners were determined: the plan is a square with its corners cut off. 

Carpenter squares began to be manufactured in the States - not imported from Britain - around 1820. They had true 90* corners and consistent dimensions. 3/4/5 triangles and rectangles were easy to lay out accurately. An inexperienced carpenter could erect a  simple frame without much worry. A master carpenter working with church members as a volunteer crew could expect his crew to build a reasonably accurate frame.

Part 2,  the design of the exterior of the church is here: https://www.jgrarchitect.com/2018/04/the-baptist-church-of-steetsboro-ohio.html

 

7/27/22: I wrote this post in 2018. When I reviewed it recently, I saw how much needed to be revised, simplified; how much I'd learned about using geometry in construction during the last 4 years.  Understanding Practical Geometry (the name Asher Benjamin and Peter Nicholson used) is an on-going exploration.

The Baptist Church of Streetsboro, Ohio, Part 2

The Streetsboro Baptist Church, built c. 1820: the second phase of its construction - its decoration - the front facade and the steeple.

 

 

The first post* discussed how the framer used the geometry of the 3/4/5 Triangle to layout the floor, the bents, the walls and  windows, the roof and steeple. After the framers made the building 'tight to the weather',  joiners would often be responsible for the finish work: window sash, doors, molding.  Different trades had different skills and tools.

I think this division of labor happened here.

 

The church front on a cloudy day in October. It is a handsome building. It is also a box decorated with boards and moldings. That's what I am looking at in this post.

The HABS drawing is below.





 

 

The windows had been set by the framer when he laid out the floor plan, the walls, and the roof frame. The black lines show what the front wall would have looked like when the joiner began his work. Holes for windows, a space - perhaps a larger framed opening - for a door, a triangular gable. 


The congregation expected that this box with a roof would become a modern Greek Revival church. 

Of course the joiner was considering the pediment, the frieze, the architrave. the water table. He also needed to lay out a facade which has grace and rhythm as well as symmetry.

 

Here is the geometry of the facade as the framer knew it: 3 bays with their height from the floor to the roof trusses, their width between the corner posts, and a door, centered but of undetermined dimensions. The windows are centered within the  3/4/5 rectangles of  the frame's rhythm. Their shape is 2- 3/4/5 rectangles.
 

 

I think, the joiner chooses to balance the windows first, to set them as supporting wings to the central door. The corner boards grew to become paired columns balanced by 2 more columns on the other side of the windows. Note that the columns are not on the lines of the bays, therefore the center bay is slightly wider than the side bays. The window bays became back drop to the central bay with its  double door and paneled transom.The joiner 'adjusted' the geometry; but the window bays' symmetry is so strong it is hard to catch. The tall, broad main door, recessed  in the main bay, then surrounded by the columns and the frieze, becomes the focus. 

The joiner 'fooled the eye' and created a dynamic facade, much better than 3 equal rectangles would have been.

 

The framer built the base which supported the steeple. Its dimensions at the roof are based on the 3/4/5 Triangle.


 

The steeple uses neither the geometry of the frame nor that of the front facade. It is a series of blocks, decreasing in size, with their corners clipped. The design uses the square and the circles that fit within and without it. Was it the work of the same joiner? **



The HABS drawing shows the steeple sections.

Here I have added the circles  - In 'A' the red circle is outside, the green inside. In 'B' that green circle is now outside, a new smaller red circle inside. 'C' continues the progression with the red circle from 'B' now the outside. The green circle of  'C'  is the base of the spire.

 The steeple layout follows the  drawings of James Gibbs in his book "On Architecture", published in England in 1728. Copies were in the Colonies, available to builders.  I have written about Gibbs' steeples here: https://www.jgrarchitect.com/2022/02/james-gibbs-steeples.html  

 These  HABS measurements are too simple for an in depth study of the steeple geometry.






The shapes that make up the tower are a series of blocks with related faces all derived from the simple manipulation of the square: a complete square, 2 squares, one square, half a square (the base for the spire).
The spire's height uses the width of the steeple's base as its unit of measure: it is 1.5 times as tall as the base is wide.
 

The paneling, edge moldings,  and the series of roofs as the tower extends create the steeple.







The  door itself is approximately square, the transom: half a square. They are the same size as the section of the steeple which holds the bell.



The wall of that bay acts as a setting,  a frame for the door.  The columns and architrave are a second frame.


 
   

Look again at the photographs.


The church's grace and presence come from simple proportions in the design and the understanding of how light and shadow give life to the parts themselves and thus to the whole building. 

Here is what Asher Benjamin wanted the joiner - and by extension, we who see the church - to understand about moldings :  

"...the bending, or turning inward, of the upper edge of the Grecian, or quirk ovolo, when the sun shines on the surface [and] causes a beautiful variety of light and shade, which greatly relieves it from plane surfaces, and if it is entirely in shadow, but receives a reflected light, the bending or turning inward, at the top, will cause it to contain a greater quality of shade in that place, but softened downward around the moulding to the upper edge."   ***

** The Sandown, NH, Meeting House and Gunston Hall in Virginia are good examples of this separation of craft. At Sandown a skilled joiner built the main door and the pulpit, perhaps the wainscotting and box pews. George Mason of Gunston Hall brought William Buckland from England to create the porches and interiors for his new brick house.

The Miller's Toll, Bennington, VT - its construction




The Miller's Toll is a restaurant in Bennington, Vermont. 

This post is about the building's construction.


The current  owners knew they had an old building when they began renovation in 2017. 
I asked to explore the place while its frame was visible. They agreed, with pleasure.
I wrote about its history on my blog, 'Passing By'*.


The main house, now surrounded by first floor wings and a second floor jut-out, is a post and beam frame with plank walls.
This framing system is not uncommon locally. Occasionally plank walls were used in western NY and Ohio; indicating that framers who had learned their trade here built there. 

First:  what I saw and some history.






 
This is part of the plate for the roof of the back wing. It was now part of the 2nd floor wall frame.
This back wing may be the original house - a small raised cape (half walls on the 2nd floor - modified Anglo-Dutch frame) typical for this part of Vermont.
The main house may have been added as the owners and the town grew.


 
The building is on every map we have of the town. It is a black spot on the first - the 1835 Hinsdill map. It is also a spot without a name on the 1856 Rice and Howard map.

 

This is part of the 1867 Beers Atlas map.The house is in the middle with the owner's name (illegible) jutting up. M C Morgan's house - now the Safford Inn - is just to the right, across the Walloomsac River.
The Safford family were early settlers of Bennington. They built the house and ran the corn and saw mills across the road. The mills are depicted on both maps. M.C. Morgan inherited the house.











 
Here is a small part of the 1877 Bird's Eye View Map of Bennington. and the same map updated in 1887.




In the middle, beside the Walloomsac River,  above and left  of the bridge, is the house.
It is a 2 story house with a back wing and a porch on 2 sides. There are 3 windows on the second floor in the front and a chimney in the middle.






It appears that the front porch was enclosed by 1887, or perhaps the delineator was more skillful.








  


The hole in the roof for the chimney is now patched. It is right where the map placed it.

It's the house which was here in 1877.

The front wing had one chimney and no fireplaces. Cast iron stoves were manufactured locally as early as 1820. This house probably had one. 





 A view inside the 2nd floor of the front wing, probably built   before 1830. 

The 3 windows seen on the map are there.
The roof has the same pitch with the gable facing the street.
The bunch of wood in the  photograph in the middle of the floor - where the surface changes -  covers the hole where the chimney was.

The gable of the house faces the street, an early step in the evolution from late Georgian to Greek Revival vernacular architecture. However, I could see no framing showing a stair had been located in a hall on one side of the front wing, also a hallmark of Greek Revival.
A simple stair was set between the back wing and the new one.  The pale sliced rectangle, lower left, is the first step for that stair. Its frame was not visible, its moldings cobbled together - I couldn't date it.



The ridge beam, running down the middle of the picture, has 5 sides. These ridge beams were standard in Bennington houses from c. 1770 to the Civil War. Wide boards with wane were used for roof sheathing.





The ceiling joists ran parallel with the  ridge, set into the beam. This is also common locally. In the photograph a later ceiling frame is barely visible.
I saw no scribe marks; this is a square rule frame.









The post and beam frame, painted here in the photo, is typical of New England timber frame construction found in Bennington from 1765 into the 1860's.
  






The walls have no studs. Instead planks sit side by side.  Bennington had lots of wood. Water powered saws quickly cut that wood into many wide panels. The intermediate studs we had earlier used in the post and beam frame gave way to plank walls.

The availability of wide boards was due to advances in saw mill technology. The contemporary sash saw could cut several boards at once; earlier saw cut only one board at a time. The proliferation of these boards may be part of why we began to add wide corner boards, wide frieze boards under the eaves, to outline pediments in gables -  to cover our simple, traditional house shapes in Greek Revival decor.  




Those planks were cut at Safford's saw mill just across the Walloomsac River.
The sash saw blade went up and down. It left the marks on the boards which are still visible today - the left side in the photograph.

On the right side are the light and dark marks left from where lath was nailed on for plaster. The uneven lines mean that the lath was 'split'  - made from  boards. Later lath is all one width cut instead of being split. 







In1896 the Sanborn Insurance map labels the house a Cigar Manufactory" . Here is the owner's advertisement in the 1896 town directory.
Later it became a market, then a restaurant - The Vermont Steak House, Peppermills, and now The Miller's Toll.


 




When I posted a link on a local history page a lively discussion took place on cigar manufacturing and small town employment in the early 1900's. The outer layer of the cigars came from Connecticut River Valley tobacco fields, the delivery made possible by the railroad to N. Adams that used the Hoosick Tunnel, an engineering feat for its era.
Young women with nimble fingers were employed to roll the cigars. Immigrants were usually hired as speaking English was not required.
