PROVISIONAL SPECIFICATION.
Improvements in the Construction of Sash Cord Pulley Brackets
and other like Brackets.
I, ALBERT HENRY ADCOCK, of Crown Works, Conybere Street, Birmingham,
Brassfounder, do hereby declare the nature of this said invention to be as
follows:-
This invention consists of the improvements herein described in the construction
of metallic brackets or frames for sash cord pulleys and for pulleys or rollers for
sliding doors and for other purposes.
A bracket of this kind consists of two sides formed with a base, the pulley or
roller being carried between these sides and its axle turning in bearings therein.
The said sides with the roller between them are recessed into the window frame or
other part to which the bracket is fixed the base being secured flush thereto by
screws and in some cases covered by a brass plate.
By my invention the cost of the manufacture of the said brackets is very
considerably reduced and when the bracket is fixed in position the pulley or roller
and its bearings can be readily removed for inspection or repairs and readily
replaced without removing the base of the bracket.
In carrying out my invention I. make the said two sides of the bracket from
sheet metal separate from the base and I provide an oblong hole in the base to
admit the two side plates and the pulley or roller between them. The side plates
and the base are notched to engage together and to maintain the side plates the
proper distance apart so that when the cover plate is fixed to the front of the base
(which is done by screws) the side plates are secured in position, but by first removing
the cover plate they and the pulley or roller can readily be removed from the front
of the bracket and replaced without disturbing the base.
One or more distance pieces may be provided between the side plates.to further
assist in keeping the side plates the proper distance apart. The said distance
piece is, or each of the distance pieces are, removably fixed to the side plates by
being notched' to a dovetailed forin at each end to engage with countersunk oblong
holes in the side plates. The distance piece is, or the distance pieces are, oblong
in cross section corresponding with the said holes in the side plates so as to
pass therethrough into position and then by a part turn to engage therewith.
The bearings of the pulley or roller axle in the side plates are or may be
bushed with brass or other metal, each of these bushes being formed with a flange
on the inside thus giving long bearings to the axle.

Improvements in the Construction of Sash Cord Pulley Brackets
and other like Brackets.
1; ALBERT HENRY. ADCOCK, of Crown Works, Conybere Street, Birmingham,
Brassfounder, do hereby declare the nature of this invention and in what manner
the same is to be perforined, to be particularly described and ascertained in and by
the following statement :--
This invention consists of the improvements herein described in the construction

page_text: '
of metallic brackets or frames for sash cord pulleys and for pulleys or rollers for
sliding doors and for other purposes.
A bracket of this kind consists of two sides formed with a base, the pulley or roller
being carried between these sides and its axle turningin bearings therein. The
said aidos with the roller between them are recessed into the window frame or other
part to which the bracket is fixed the base being secured flush thereto by screws
and in some cases covered by a brass plate.
By my invention the cost of the manufacture of the said brackets. is very
considerably reduced and when the bracket is fixed in position the pulley or roller
and its bearings can be readily removed for inspection or repairs and readily
replaced without removing the base of the bracket.
I will describe my invention by referring to the accompanying drawing on
which
Fig. 1 represents a sash cord pulley bracket constructed according to this
invention complete with the pulley and axle,
Fig. 2 represents the same with the front or cover plate removed;
}
Fig. 3 is a sectional elevation of the same shewing how the two side plates of
the bracket and the pulley or roller can be removed without unfixing the base:
Fig. 4 shews the said base separately in front and sectional elevations:
Fig. 5 is a back elevation and Fig. 6 a side elevation, and Fig. 7 a sectional
elevation of the two side plates and the pulley or roller carried thereby.
In carrying out my invention I make the said two sides A' A of the bracket
from sheet metal separate from the base B and 1 provide an oblong hole C in the
base B to admit the two side plates A' A2 and the pulley or roller D between
them. The side plates A¹ A? are notched at a a² and the base B is notched
at corresponding with the notches a' a of the side plates so that when
the side plates A'A' with the pulley or roller D between them are placed in
position in the oblong hole C in the base as shewn in Fig. 2, the notched parts a' a²
of the side plates will engage with the notches of the base B as shewn in
Figure 2 and thus maintain the side plates A' A² the proper distance apart so that
when the cover plate E is fixed to the front of the base B (which is done by screws
as shewn in Fig. 1) the side plates A' A² are firmly secured in position as the said
notched parts prevent the side plates A' A passing through the base B and the
cover plate E prevents the side plates A¹ A2 coming outwardly. By. first
removing the cover plate the side plates and the pulley or roller can readily
be removed from the front of the bracket as shewn by Fig. 3 and be replaced
without disturbing the base B.
One or more ordinary distance pieces such as G may be provided between the
-side plates A' A² to further assist in keeping the side plates the proper distance
apart. This distance piece G shewn on my drawing consists of a piece of tube G
of a length to fit between the side plates A' A². An ordinary screw g passés
through the plates AA2 and the distance piece G and secures them together and
enables the plates A1 A2 to be readily taken apart when required.
The bearings of the pulley or roller axle I in the side plates A1 A2 are or may
be bushed with brass or other metal see Fig. 7, each of these bushes H H being
formed with a flange on the inside thus giving long bearings to the axle; the
bushes H H are secured in place by being rivetted over on the outside at A².
I construct pulley or roller brackets for sliding doors and for other purposes
with removable sides similarly as above described with reference to a sash cord
pulley bracket.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed declare that what 1
claim is :-
i. Making the sides (such as A' A²) of a sash cord pulley bracket or other like
bracket separable. from the base (such as B) thereof and removably securing the
said sides and tlie base together in the manner substantially as hereinbefore described

page_text: and illustrated by the accompanying drawing so that the sides and the pulley or
roller can be removed from the base by first removing the front or cover plate as
herein before set forth.
2. The construction combination and arrangement of parts constituting the
improved sash cord or other pulley or roller bracket herein before described and
illustrated by the accompanying drawing.
