An Improved Pulley Block.
We, ALFRED MARCONI WHITE, Shipwright, of Conyer's Quay, Teynham, Kent.
and ARTHUR CHRISTOPHER DAVEY, of 88, West India Dock Road, London, E.,
Iron Block Manufacturer, do hereby declare the nature of this invention to be
as follows:
An improved pulley block where two or more sheaves are used, whereby is
obtained a saving of labour and increased purchase.
We construct each sheave with a solid or fixed axle, and in the cheeks of the
block we make or insert or attach a collar or bush on and within which the said
axle revolves. The cheeks of the block are held together in the usual manner,
but the sheaves revolve upon their fixed axles instead of upon the usual loose
pins.
The sheaves may be made of hard wood with a metal axle securely fixed or the
sheave and axle may be made entirely of metal. The frames or checks of the
block may be either of wood with the metal bush securely fixed into position
or entirely of metal.

CHRISTOPHER DAVEY.
We, ALFRED MARCONI WHITE and ARTHUR CHRISTOPHER DAVEY, both of 88,
West India Dock Road, London, 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 relates to an improved pulley block where two or more sheaves
are used, and has for its object a saving of labour and obtaining increased
purchase.
We construct each sheave with a solid or fixed axle, and in the cheeks or
flanges of the block, we make, insert, or attach a collar or bush in which the
said axle revolves.
The checks or flanges of the pulley block are held together in the usual
manner, but the sheaves revolve upon their fixed axles instead of upon the usual
loose pins.
The sheaves may be of hard wood with a metal axle securely fixed, or 'the

page_text: sheave and axle may be made entirely of metal. Likewise the frames of
the checks or flanges of the block may be either of wood with the metal bush
securely fixed into position or may be entirely of metal.
In order that our invention may he readily understood, we will describe the
same with reference to the accompanying drawings in which Fig. 1 represents
a section through the improved block, shewing the axle fixed to or solid with
the sheave as hereinbefore mentioned, Fig. 2, is an elevation of one of the checks
or flanges of the pulley block, with the pulley and solid axle, and Fig. 3, is
another elevation of the pulley block, shewing the collar or bush in which the
axle of the pulley revolves.
In these views A is the pulley, having the axle 13, solid with, or otherwise
fixed to the pulley. C is the collar or bush either solid with, or fixed to the check
or flange of the pulley block, in which the pulley axle aforesaid revolves. D.D
are the aforesaid cheeks or flanges of the pulley block.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. In a pulley block, the provision of an axle or axles, solid with, or fixed to
the pulley or pulleys, said axle or axles revolving in collars or bushes, solid
with, or fixed in the cheeks or flanges of the pulley block, substantially as and
for the purpose herein set forth, and described and illustrated by the accom-
panying drawings.
2. The application of this invention to any form or kind of pulley block, sub-
stantially as and for the purpose herein set forth and described and illustrated
by the accompanying drawings.
