Joist and Rafter Shoes.
-
WILLIAM GEORGE JOSEPH HOOPER LEWTON, of 6, The Forbury, Reading,
Berks, Architect, do hereby declare the nature of this invention to be as follows:-
My invention of joist and rafter shoes is intended to supercede the use of
the ordinary wood bond or plates, sleeper joists and wall plates usually built
into walls of buildings to support the floor joists, and rafters of roofs.
The joist and rafter shoes would be manufactured in terra cotta, stoneware,
earthenware, and brick, artificial stone, or cement, made in various sizes to suit
the several thicknesses of joists and rafters. The joist shoes would be built into
the walls where the joists run into walls and they would be supported on brick
piers or walls where the joists occur to ground floor storeys of buildings. The
joist shoes for ground floor joists would be channel shaped (like the letter E
without the centre arm) and the shoes for joists built into walls would be of
similar shape but with a stopped end at back.
The rafter shoes would be built into walls and would have flanges on the
bottom edges of shoes to clip over brickwork or stonework of walls to prevent the
shoes being pushed out of place by the thrust of the rafters. The rafter shoes
would have wings at either side to keep the rafters in position and centre_blocks
between wings over which the rafters would be notched,, and flanges at bottom
edges of shoes to clip over brick or stonework of walls.

Joist and Rafter Shoes.
WILLIAM GEORGE JOSEPH HOOPER LEWTON, of No. 6, The Forbury, Reading,
Berks., Architect, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
My invention of joist and rafter shoes is intended to supersede the use of
ordinary wood bond or plates, sleeper joists and wall plates, usually built into
walls of buildings to support the floor joists and roof rafters.
The joist and rafter shoes would be manufactured in terra cotta, stoneware,
earthenware, brick, stone, artificial stone, or cement.
The joist shoes would be built into the walls where the joists occur in the
upper floors of buildings, and they would be supported on brick or concrete piers
or walls where the joists occur on ground floor storeys of buildings.

page_text: The joist shoes for ground floor joists Figures 1 and 2 would be channel shaped
with small grooves for the circulation of air marked A on drawing and would be
made in various sizes to suit the different thicknesses of joists.
The shoes for support of ends of joists in external walls of ground floor storey
Figure 4 would have stopped ends at back marked B on the drawing.
The joist shoes for upper floor joists Figure 3 would be channel shaped with
small grooves for the circulation of air marked A on drawing. The shoes for
support of ends of joists in external walls of upper floor storeys Figure 4 would
have stopped ends at back marked B on drawing and shoes would be made in
various sizes to suit the different thicknesses of joists.
The rafter shoes Figures 5 and 6 would be built into walls and would have
flanges marked C on drawings on back edges of shoes to clip over brickwork or
stonework of walls to prevent the shoes being pushed out of place by the thrust
of the rafters. The rafter shoes would have wings on either side marked D on
drawing to keep the rafters in position and centre blocks between wings marked E
on drawing over which the rafters would be notched.
It will be seen that the grooves a run parallel to the joist so that in the case of
the channel section a current of air passes along the bearing parts while in the
case of those having stopped ends for external use the grooves may be retained
round the bearing part next the stopped ends.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1st. The channel shaped shoes for joists, having air grooves a running parallel
with joists, substantially as and for the purpose herein set forth and illustrated.
2nd. The external wall shoes for joists having side flanges and stopped ends
with air grooves a on the bearing part substantially as and for the purpose herein
set forth and illustrated.
3rd. The rafter shoes having flange C, wings D, and block E, substantially as
and for the purpose, herein set forth and illustrated.
