Maker do hereby declare the nature of this invention to be as follows:-
This invention consists of certain improvements in axle pulleys, such as are used on
sash-frames for the purpose of receiving the cords attached to window sashes and
which are also used in various positions to receive cords or chains.
The ordinary kind of axle pulley frame is made with two side cheeks projecting
from a face-plate, in which is formed an opening of.suitable dimensions to allow the
axle-pulley to project through the opening beyond the face of the said face-plate; a
suitable grooved pulley is then placed between the side cheeks; a hole is pierced
through the side-cheeks and also through the boss of the pulley; an axle pin is then
passed through one cheek thence through the boss of the pulley and thence through
and out at the other side cheek.
Axle pulleys fixed in the manner hereinbefore described frequently get out of smooth
working order the axle-pin works loose in the side cheeks and revolves in the pulley
and side-cheeks, instead of remaining a fixture; the pulley also revolves on the axle ;
this alternate and double action of the spindle revolving in the pulley and the pulley
on the spindle eventually wears an oblong hole in the pulley thus causing the
pulley to revolve with an excentric jerkey action instead of revolving smoothly and
continueously; to remedy the defects set forth I make my improved pulley and
pulley-frame in the following manner.
I form a trunnion on each side of the pulley.
I also form a slot in each cheek of the pulley-frame the centre of the slot may be
at any convenient angle with the face-plate, by preference it would be at an angle of
30 degrees.
It will thus be readily understood that the pulley can be lowered into position.
between the side cheeks and that the trunnions would slide down the slot until they
reached the cemicircular bottom thereof the trunnions of the pulley will thus revolve
in the cemicircular bottoms of the slots.

page_text: The frame and pulley so connected together would be ready for use; when in wear
the weight attached to cord would press the cord against the groove formed in the
edge of the pulley and thus press the pulley trunnions into their slot-bearings.
By the revolving of the trunnions in the slot bearings, the bearings would wear
concave to suit the gradually diminishing diameter of the trunnions.
To prevent the pulley from falling out of its frame when handled for purposes of
sale or delivery to users I pass a piece of wire accross the opening between the
cheeks, the wire may be screwed into the cheeks and riveted, or secured by other
equivalent mechanical means.
In other cases I provide a sliding cap to fit in the slot, one end of the sliding cap
would be hollowed to fit over the trunnion.
Or in lieu of the sliding cap I can in some cases provide loose trunion bearings
made in halves, in such cases a concave half would be lowered down each slot, the
pulley then lowered so that its trunnions took a bearing in the bottom halves of
bearings the top halves would then be lowered over the trunnions.
I can also in some cases provide a cover to reach from cheek to cheek for the
purpose of covering the outlet end of the slots provided in each cheek, this
cover would take the place of the piece of wire passed accross the opening between
each cheek.
Axle-frames and pulleys made in the manner set forth can be produced at a less
cost than by the old method of making axle pulleys and frames, and when made they
will wear a greater length of time and work easier than the old style of manufacture.

page_text: I ALFRED ASHMORE of Tividale Road, Tipton in the County of Stafford Axle-pulley
Maker 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 consists of certain improvements in axle pulleys, such as are used on
sash frames for the purpose of receiving the cord attached to window sashes and
which are used in various positions to receive cords or chains.
The ordinary kind of axle pulley frame is made with two side cheeks projecting
from a face plate in which is formed an opening of suitable dimensions to allow
the axle pulley to project through the opening beyond the face of the said face-.
plate: a suitable grooved pulley is then placed between the side checks: a hole is
pierced through the side cheeks and also through the boss of the pulley: an axle
pin is then passed through one cheek, thence through the boss of the pulley and
thence through and out at the other side cheek.
-
Axle pulleys fixed in the manner hereinbefore described frequently get out of
smooth working order, the axlo pin works loose in the side cheeks and revolves
in the pulley and side cheeks instead of remaining a fixture; the pulley also revolves
on the axle; this alternate and double action of the spindle revolving on the pulley
and the pulley on the spindle eventually wears an oblong hole in the pulley thus
causing the pulley to revolve with an excentric jerky action instead of revolving
sinoothly and continuously. To remedy the defects set forth I make my improved
pulley and pulley frame in the following manner.
I form a trunnion on each side of the pulley.
I also form a slot in each cheek of the pulley frame, the centre of the slot may be
at any convenient angle with the face plate, by preference it would be an angle of
30 degrees.
:
It will thus be readily understood that the pulley can be lowered into position
between the side cheeks, and that the trunnions would slide down the slot untill
they reached the semicircular bottom thereof, the trunnions of the pulley will thus
revolve in the semicircular bottom of the slots.
The frame and pulley so connected together would be ready for use: when in
wear the weight attached to cord would press the cord against the groove formed
in the edge of the pulley and thus press the pulley trunnions into their slot bearings..
By the revolving of the trunnions in the slot bearings, the hearings would wear
concave to suit the gradually diminishing diameter of the trunnions.
To prevent the pulley from falling out of its frame when handled for purposes of
sale, or delivery to users I pass a piece of wire across the opening between the
checks, the wire may be screwed into the cheeks and riveted or secured by other
equivalent mechanical means.
In other cases I provide a sliding cap to fit in the slot, one end of the sliding cap
would be hollowed to fit over the trunnion.
t
Or in lieu of the sliding cap I can in some cases provide loose trunnion bearings
made in halves in such cases a concave half would be lowered down each slot, the
pulley then lowered so that its: trunnions took a bearing in the bottom halves
of bearings the top halves would then be lowered over the trunnions.

page_text: I can also in some cases provide a cover to reach from cheek to cheek for the
purpose of covering the outlet ends of the slots provided in each cheek, this cover
would take the place of the piece of wire / passed across the opening between each
cheek.
Axle frames and pulleys made in the manner set forth can be produced at a less
cost than the old method of making axle pulleys and frames and when made they will
wear a greater length of time and work easier than the old style of manufacture."
I will now proceed to describe with reference the accompanying drawings, the
manner in which my invention is constructed and used.
Figure 1 represents an horizontal view or plan of an axle pulley frame face plate.
Figure 2 represents a side view of the axle pulley frame in position for moulding in
the direction shewn by dotted lines.
Figure 3 represents an axle pulley frame in position to mould vertically with the
slot d.
Figure 4 represents a section of figure 2 on the line A B.
Figure 5 represents a section of figure 6 on the line C. D.
Figure 6 represents the axle pulley frame connected to the axle pulley and slot
cover h.
Figure 7 represents a solid bearing.
Figure 8 represents a side view of the axle pulley frame with the axis of slot at
right angles with face plate.
Figure 9 represents an end view of figure 8.
Figure 10 represents a section of figure 6 on the line C. D. shewing a modification
suitable to receive the bearing figure 11.
Figure 11 represents a vertical elevation of bearing suitable for use in the sectional
arrangement shewn at figure 10.
Figure 12 represents an end view of figure 11.
Figure 13 represents an axle pulley.
Figure 14 represents a single top axle bearing.
Figure 15 represents a double top axle bearing.
Figure 16 represents a side view of figure 15.
Figure 17 represents a plan of figure 14.
In carrying out my invention I, in some cases form my axle-pulley-frame in the
manner illustrated at figures 2 and 3 that is to say I provide the ordinary shaped
face plate a connected to two side cheeks b and provide trunnion bearings c in each
side cheek. The slot d is formed in the cheeks leading to the trunnion bearings c.
In some
cases I draw the patterns out of the sand in the angular direction
represented in dotted lines at figure 2 in such cases it can be readily understood
that the axle pulley frame is made or cast with its slot d and counter sunk screw
holes e without using cores.
In other cases I draw the pattern out of the sand in the vertical direction represented
at figure 3 the slot d and counter sunk screw holes e would then also be cast without
cores.
In other cases I lift the pattern vertically and cast the slot d in the position shewn
at figure 8.
I am aware that axle pulley frames have been made with a short inlet or slot leading
to the axle pulley trunnion bearings, as described in Specification No. 4607 year 1884
but such inlets are formed in corrugated cheeks: I am also aware that a corrugated
system has been previously described in Specification No. 3532 year 1881, therefore
seeing that two Patent applications have been made for the system of corrugated
cheeks I do not intend to utilize or claim such corrugated configuration of axle-
frame-cheeks in which to form my slot d, because by the utilization and adoption
of the ordinary flat surfaced cheeks in which to form my slot d I am enabled to
cast my slotted axle pulley frames without the use of cores: whereas the corrugated
or circular series-shaped-cheeks when provided with a slot in the manner illustrated
and described in Specification No. 4607 year 1884 cannot be cast without the use of
cores.

page_text: The making of axle pulley frames with plane or flat surfaced side cheeks in which
are provided axle bearings and in which are also provided slots & leading to such
axle bearings constitute the essential part of my invention because I can manufacture
such axle-pulley frames without the use of cores.
In some cases I make my axle pulley frames in the manner shewn at figure 6 with
the slots d covered with a wall or plate as shewn at figure 5 I can then lower the
trunnions of axle pulley figure 3 into the bottom bearings c and afterwards lower a
pair of single top bearings similiar to figure 14 over the trunnions securing these top
bearings by means of the cover h.
In other cases the side view shewn at figure 6 would be adopted but the transverse
section of such side view would be widened or extended in the manner shewn at
figure 10. In utilizing frames so made a bearing similiar to figures 11 and 12 would
be passed on to each trunnion of the axle pulley figure 13, the axle pulley with its two
bearings would then be lowered into position, the V shaped projections formed on
the bearings would slide down the slots j in other cases I pass circular bearings
similiar to figure 7 on to the trunnions of axle pulley and lower them into the frame
to take a bearing at the bottom of the slot d.
In other cases I lower the axle pulley into the bottom bearings provided in the side
cheeks of axle frame and then lower a double axle bearing similiar to figures 15 and 16
over the trunnions of pulley. When using the single or double axle bearing in axle
frames of the transverse section shewn at figures 4 or 5 the bearings can be secured in
position by means of a rivet or pin passing through the walls f into the holes k
provided in bearings: in some cases I form the slot d with its axis at right angles
with the face plate a, the slot may be open as represented at figure 8 or it may be
covered on each side with a wall similiar to figure 5.
When using a pulley similar to figure 13 in connection with a pulley-frame I
can in some cases dispense with the top bearing similar to figure 14 and also with
the bearing cover shewn in use at figure 6: in such cases in order to prevent the
pulley from falling out of its frame when handled for purposes of sale or delivery
to users I pass the piece of wire through one side or cheek of pulley-frame,
thence across the opening and thence out through the other side or cheek of pulley-
frame.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what [
claim is
1st. The making of an axle-pulley-frame with each flat side or cheek pierced with a
slot reaching to the axle-pulley trunnion bearing such slot being formed in conjunction
with the side cheek in such a manner that the axle frame can be cast without the use
of cores as illustrated and described.
2nd. The combination with an axle pulley frame of either of the bearings
represented at figures 7, 11, 12, 14, 15, 16, and 17 in conjunction with the trunnions
of an axle pulley working in the axle pulley frame.
3rd. The combination with an axle-pulley frame of the slot cover or its
equivalent, a pin or wire l, as illustrated and described for the purpose described.
