AN IMPROVED MANUFACTURE OF SASH-PULLEY
Year: 1882

page_text: LETTERS PATENT to William Meakin, of 84, Baker Street, London, W., in
the county of Middlesex, Manufacturer, for an Invention of "AN IMPROVED
MANUFACTURE OF SASH-PULLEY."
PROVISIONAL SPECIFICATION left by the said William Meakin at the
Office of the Commissioners of Patents on the 21st February 1882.
WILLIAM MEAKIN, of 84 Baker street, London, W. in the County of Middlesex,
Manufacturer "AN IMPROVED MANUFACTURE OF SASH-PULLEY."
This Invention has for its object the production of the strongest and most
durable pulley at a inoderate cost, and accomplishes this by combining the use of
a frame-casting, moulded in one piece, with a provision for lubrication of the
pulley-axle.
I make the frame or box which carries the axle-pulley of a single casting, some-
what similar in shape to the ordinary built up frame, and in each of the side plates
I form a straight slot leading backwards and downwards from the front face of
the box: the lower ends of these slots are circular, and form the bearings for the
pulley-axis. This construction enables the pulley to be cast in one piece with its
axle, and dropped into place from the front, and a removable cover plate of
suitable form is provided, which screws on to the front-plate of the frame, covering
the two slots, and preventing the pulley from coming out of place. Two holes are
provided in this plate, one on each side, just above the lower face of the slots in
the side plates of the frame, so that when oil is introduced through these holes, it
runs down the sloping faces of the slots, to lubricate the bearings in which the
axle of the pulley revolves.

WILLIAM MEAKIN of 84 Baker Street London W. in the County of Middlesex
Manufacturer. "AN IMPROVED MANUFACTURE OF SASH PULLEY."
This invention has for its object the production of the strongest and most
durable pulley at a moderate cost and accomplishes this by combining the use of a
frame-casting, moulded in one piece, with a provision for lubrication of the pulley
axle.
I make the frame or box which carries the axle-pulley of a single casting, some-
what similar in shape to the ordinary built-up frame, and in each of the side
plates I form a straight slot leading backwards and downwards from the front face
of the box the lower ends of these slots are circular and form the bearings for the
pulley axis. This construction enables the pulley to be cast in one piece with its
axle and dropped into place from the front, and a removeable cover plate of
suitable form is provided which screws on to the front-plate of the frame covering
the two slots and preventing the pulley from coming out of place-Two holes are
provided in this plate, one on each side, just above the lower face of the slots in
the side plates of the frame, so that when oil is introduced through these holes it
runs down the sloping faces of the slots to lubricate the bearings in which the axle
of the pulley revolves.
In order that my invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.-
DESCRIPTION OF THE DRAWINGS,
Figure 1 is a front view of my sash pulley in place--Figure 2 is a side view and
Figure 3 a horizontal section.
a is the frame or box which is cast in a single piece-b is the pulley and 6¹ its
axis c is the front plate having holes c'. c' in it for oiling.
Having thus described my invention and the manner of performing the same I
would have it understood that what I claim is, the manufacture of the sash pulley :
substantially as described.
In witness whereof I the said William Meakin have hereunto set my hand
and seal this nineteenth day of August in the year of our Lord One
thousand eight hundred and eighty two.
