I, FRANK SIDEBOTHAM RIPPINGILLETrading as the Frank Rippingille
Stove Company, of Plume StreetAston in the Countyorof Warwick, Manu-
facturer, do hereby declare the nature of this invention and ins what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:
La li
This invention consists of improvements, relating to wheels or pulleys for guiding
driving ropes, and for other like purposes tmy object being to arrange a pulley of
simplexform and construction, having a hollow interior for the reception of oil or
other lubricant, in combination.with a supporting, arm or bracket, and a stand or
base piece, in such a manner that the pulley can be readily fixed for working, in
any required position without displacement of the central pivot pin..
In order that my invention and the method of carrying the same into effect may
be the more readily understood, append hereunto one sheet of explanatory
drawings to be hereinafter referred to
Figure 1 is a front elevationpandiDigure 2alsectional end elevation representing
one convenient form of my combined pulley, bracket and stand, adapted for service
as a punkah wheel for guiding the rope or cord employed in the operation of a
punkah.
Figure 3 is a front elevation of the complete punkah wheel as fixed in its
horizontal position.
The same référence letters in the different views indicate the same parts.
I construct the wheel or pulley A with two solid side webs or plates A and A',
enclosing a circular space B for the reception of the oil, grease, or other lubricant.
A boss is formed at the centre of each web, and these are bored out to receive the
pivot pin C. One end of the pivot pin C is turned down to pass through the
boss D¹ of the arm or bracket, D, and also through the ropesguard E.interposed
between the pulley and the bracket, the outer end of the guard being formed to a
hook like shape as illustrated in order to prevent the rope from slipping out of the
groove of the pulley. The guard E can be adjusted to any desired position by
turning it upon or about the pin C before the same is tightened up. On-screwing
or. tightening up the pin C by means of the nut C, or in any other convenient
manner, the pin C, the guard E, and the bracket D are all secured together. The
pulley A is carried or supported upon the pin C between the underside of the head
and the guard E as shown at Figure 2, the bosses of the pulley fitting sufficiently
close against the pin head and the boss of the guard to prevent escape of the
lubricant, but without impairing the freedom of the revolution of the pulley upon
the pin. I sometimes interpose a loose collar, or washer with a spiral or other
suitable spring between the guard E and the pulley or between the underside of
the pin head and the pulley, or I adopt other convenient means for the purpose of
maintaining the contact between the pulley bosses and the fixed bearing pieces:
To prevent rotation or movement of the guard E'I sometimes provide serrated
edges on the adjacent faces of the guard and bracket bosses as shown at
Figure 3.
The boss D2 at the opposite end of the arm or bracket Dis of the same
diameter as the boss D hereinbefore referred to; and both bosses. are made
suitably for fitting within the stand or base; piece F. When the pulley is

but when required in a horizontal
required. to be fixed in a vertical
boss D is fixed within the base piece
position as shown at Figure 3, the boss D' is inserted within the base, the
boss D then occupying the position shown in that figure. I preferably secure
the arin or bracket D within the stand or base plece by means of a small
screw or stud such as G.,
The stand or base piece Fis-screwed-down or otherwise attached to a horizontal,
vertical, or inclined support as required.
The application-of my infertigh to buide wheels of Buſſeys to other services
differs only in the modification of parts to suit the particular requirements, from its
application to a punkali wheel or pulley as hereinbefore described.
