MALCOLM MCCALLUM, 9, Clavering Street, Paisley, in the County of Renfrew,
North Britain, Joiner, do hereby declare the nature of this invention to be as
follows:
--
This invention relates to an improved construction in shoes or pockets for
wooden joists, whereby joists, besides their being insured against decay caused
by contact with masonry or brickwork, are made to become binders of the
walls in which their ends are placed; securing greater stability to buildings and
obviating a serious objection to the use of shoes of the pattern commonly in
use, namely their inadequacy to keep hold of the ends of the joists and secure
the walls againsts outward inclination.
The improvement consists 1st in the shoes or pockets being formed with a
raised part on upper surface of sole on which joist lies, and joists being notched
to receive same. When laid in position are rendered incapabale of being with-
drawn from shoes. 2nd. In the sides of shoes or pocket being formed in the
shape of a dovetail, thus securing against its being withdrawn from masonry.
Dated this 14th day of February 1899.

Improvements in Shoes or Pockets for Ends of Timber Joists.
I, MALCOLM MCCALLUM, of 9, Clavering Street, Paisley, in the County of Ren-
frew, North Britain, Joiner, 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:--
This invention relates to an improved construction in shoes or pockets for
timber joists whereby joists besides their being insured against decay caused
by contact with masonry or brick work are made to become binders of
the walls in which their ends are placed securing greater stability to buildings
and obviating a serious objection to the use of shoes or pockets commonly in
use, namely their inadequacy to keep hold of the ends of the joists, and
secure the walls against outward inclination.
The improvement consists 1st in the shoe or pocket being formed with a
raised part A on the upper surface of the sole on which the joist lies and joists
being notched to receive same when laid in position are rendered incapable of
being withdrawn laterally from the shoes. 2d in the sides of the shoe or pockets

page_text: heing formed in the shape of a dovetail B thus securing against its being with-
drawn from the masonry or brickwork in which it is built.
2d. The shoes or pockets are of two classe's 1st those open at the top for use
at window bossings etc. Where no building is to be placed above the joists
(Figures 3, 4, 5). 2nd those closed at top for use where building is to be placed
above the joists (Figures 1, 2, 3.)
3d. Both classe's of joist shoes or pockets will be of various sizes adapted to
the different scantlings of joists required.
4d. The open class will be of the same depth as the joist the closed class will
be deeper inside than the joist by a sufficient height to allow of the notched
joist to pass readily over the raised part of sole and drop into position with
the raised part filling the notch.
5th. The improved shoe may be made of fireclay earthenware metal or other
suitable substance.
6th. 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:
-
The raised part on sole lettered A (Fig. 2, 5) and the sides of shoes being in
the shape of a dovetail lettered B (Fig. 3).
