Improvements in Wrought-metal Split Pulleys.
I, CHARLES DARIUS WEEKS, of Akron, in the County of Summit and State-
of Ohio, United States of America, Salesman, 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 :-
My invention relates to improvements in wrought-metal split pulleys; and it.
consists in certain features of construction and in combination of parts hereinafter
described, and pointed out in the claims.
In the accompanying drawings,
Figure 1 is an end elevation of a pulley embodying my invention.
Fig. 2 is an enlarged elevation, in transverse section, of one of the arms, taken
ou lines xx, Fig. 1.
The rim of the pulley is constructed in halves A A and of wrought-metal sheets
or plates of suitable width for the face of the pulley. The one end of each rim-
section is bent at a sharp angle, as at a, to form one of the primary arms B. The
two arms B B over-lap each other and are curved outward, as at b b, to constitute
the hub of the pulley, and the hub is constructed to fit a given standard size of
shaft. The overlapping sections of arms B B are drawn together by securing or
clamping bolts 6' 6 on either side of the curved sections, whereby the hub of the
pulley is clamped so firmly to the shaft that no other fastening is required. The
other end of each rim-section is bent inward at a more obtuse angle, as at a', to form
toes A for engaging an arm B, with securing-bolts 62 for securing these parts. By
removing bolts 662 the pulley can be divided into halves, and can therefore be
readily mounted on or removed from the shaft.
CC are arms or spokes for bracing, respectively, the central portions of the rim-
section. Arms C have toes C₁ fastened to the rim, as shown, these arms having
curved sections c and straight sections c¹ for engaging the exterior of the hub and
for engaging the opposing section of an arm B, to which latter section e' is secured.
by means of the aforesaid bolts 6'. The different arms B and C, or either of them,
may be curved in cross-section-for instance, as shown in Fig. 2-to stiffen the
arms, and this would be more likely done for a pulley of large diameter and broad
face.
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 I
claim is:-
1. A wrought pulley of the split variety the rim whereof is constructed in two
sections or halves, the one end of each rim-section being bent inward to constitute
an arm, the two arms overlapping each other, the overlapping sections being curved
outward to constitute the hub, the other end of the rim-section having inwardly-
projecting toes for engaging the opposing arms, and with securing-bolts, substan-
tially as shown, for fastening the arms together and thereby clamping the hub to
the shaft and for fastening the opposing arms and toes, substantially as set forth.

page_text: 2. In a wrought-metal split pulley the rim whereof is constructed in two sections
or halves, the one end of each rim-section being integral with the pulley-arm, the
two arms overlapping each other and constituting the hub of detachable arms
having toes secured to the pulley-rim, these detachable arms having concaved
sections engaging the periphery of the hub and having adjacent sections secured to
the primary arms, substantially as set forth.
3. A split pulley comprising independent peripheral sections, each section having
an integral arm curved outwardly to form a hub, said arms secured together on each
side of the curved sections, substantially as set forth.
