We, HARRISON UNDERWOOD, (Engineer), and CHARLES.; SCHWEIZER, (Silk
Weaver), both of the City,, County and State of New York, United States of
América, do hereby declare the nature of our invention for "IMPROVEMENTS IN
SPLIT PULLEYS AND WARP BEAMS," to be as follows:"

The object of our invention is to provide new and improved split, pulleys or warp
beams, which can be placed on the shaft very easily and, locked firmly on the
same.
The invention consists in the combination with two half, pulley or beam sections.
of a split rin secured to and surrounding the sections and of bolts for clamping the
half sections on the shaft and for holding the ends of the band together..
'
The pulley is formed of, two semicircular, halves, each composed of a semicircular
rim part, having three spokes,, and a half tube.
"
The spokes, have, two opposite laterally, projecting, lugs or wings, each provided
with an aperture through which bolts having nuts are passed..
A spring, split band or rim which is wider, than the rim parts, is held to the rims
of the, sections by rivets and at each end it is provided on the inner surface with
an angle piece which is riveted on. To place the, pulley on, the shaft the two
sections are, swung from each other, the band serving as a hinge and; the shaft is
passed into the hub parts, and, the two pulley, sections are swung together and the
nuts, are, drawn up tight to clamp the hub parts on the shaft.
"
Bolts having, nuts are, passed through, the angle pieces, and the nuts are drawn
up tight..
As the band serves as a hinge, the sections can easily, be swung from each other
to permit of passing, the. shaft, between them and the pulley can be clamped
securely on the shaft by means of the bolts and nuts..
By lengthening the pulley, a warp beam is formed, which can be secured on the
sbaft in the same manner as the pulley..
The warp beam, has, a lead or end piece, formed like the above described pulley
frame at each end and if it is long, such frames may be provided between the ends.
The warp beam may be made any desired, length, is very, light and can be applied
easily.

page_text: We HARRISON UNDERWOOD (Engineer) and CHARLES SCHWEIZER (Silk Weaver)
both of the City, County, and State of New York, United States of America, 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 :--
Our Invention relates to new and improved split pulleys and warp beams which
can be very easily placed and firmly secured on the shaft.
The Invention consists in the combination with two half pulley or beam sections
of a split rim secured to and surrounding. the sections, and of bolts for clamping the
half sections on the shaft and for holding the ends of the band together.
:
Reference is to be had to the accompanying drawings forming part of this
specification in which similar letters of reference indicate corresponding parts in
both Figures.
Figure 1 is a side view of our improved split-pulley.
Figure 2 is a sectional plan view of the same on the line x-x, Figure 1.
The pulley is formed of two semicircular half sections embraced by a spring
split band or rim which serves as a hinge to unite the sections. Each section is
composed of a semicircular rim part A having three spokes B. C. and D and a half-
hub E. The adjacent spokes D of the two half sections (which are situated at the
side at which the pulley is intended to open for the purpose of placing it on the
shaft) have two opposite laterally, projecting lugs or ears F through which are
passed bolts G. The split band or rim J is wider than, and is rivetted to the
rims A of the two half sections by rivets K. and on the inner surface at each of its
ends an angle piece L is rivetted. To place the pulley on the shaft the two
sections are moved apart (the band serving as a hinge) and slipped on to the shaft
and the two pulley sections are then closed together and bolts G are inserted and
secured by the nuts H. to clamp the half hubs E. tightly on the shaft. Bolts N are
passed through the angle pieces L and secured by their nuts M.
:
A warp beam which can be secured on the shaft in the same manner as the
pulley above described may be formed by increasing the width of the band J until
it is equal to the intended length of the beam and securing it upon a pair of heads
or frames each composed of two semi-circular half sections constructed and united
like the halves of the above described pulley frame, similar intermediate frames
being used if the beam is of such length as to require support at interinediate
points.
The warp beam may be made any desired length, is very light, and can be applied
easily.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed; we declare that
what we claim is :-
:
1st In a split pulley or warp beam, the combination with semi-circular half
sections, of a split band surrounding them and secured to each section, substantially
as herein shown and described.

page_text: 2nd In a split-pulley or warp beam, the combination with semi-circular half
sections, of a split band surrounding the rims of the sections and secured to the
same, angle pieces on the abutting ends or edges of the band, and bolts passed
through the said angle pieces, substantially as herein shown and described.
3rd A split pulley or warp-beam formed of semi-circular half sections secured to
a split band serving as a hinge, which permits of separating the pair or pairs of
half sections, substantially as herein shown and described.
4th In a split pulley or warp beam, the combination with semi-circular half
sections having lugs or wings on the spokes, of bolts passed through the said lugs,
a split band surrounding the. pulley sections, angle pieces secured on the abutting
ends or edges of the band and bolts passed through the angle pieces, substantially
as shown and described.
