Year: 1876

page_text: LETTERS PATENT to James Henry Butler, of Wolverhampton, in the County of
Stafford, Hardware Manufacturer, for the Invention of "AN IMPROVEMENT IN
THE MANUFACTURE OF WROUGHT-IRON AXLE PULLIES FOR WINDOW SASHES."
Sealed the 16th March 1877, and dated the 11th December 187
PROVISIONAL SPECIFICATION left by the said James Henry Butler at the
Office of the Commissioners of Patents on the 11th December 1876.

Manufacturer.
This Invention refers to the method of constructing the description of side pieces
or cheeks which have bushes thereupon to carry the axle; according to the ordinary
method the said bushes are riveted to the cheeks.
This Invention consists in forming the said side pieces or cheeks of iron which is
rolled with a thickened part of sufficient width to act as a bush for the axle. The
expense of riveting the bush to the cheek is thus obviated, and the bush is much
firiner when formed solid to the cheek than when riveted.
The hole for the axle is punched out of the thickened part of each cheek.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Henry Butler in the Great Seal Patent Office on the 6th June
1877.
JAMES HENRY BUTLER, of Wolverhampton, in the County of Stafford, Hardware
Manufacturer. "AN IMPROVEMENT IN THE MANUFACTURE OF WROUGHT-IRON AXLE
PULLIES FOR WINDOW SASHES."
This Invention refers to the method of constructing the description of side pieces
or cheeks (for wrought-iron axle pullies) which have bushes thereupon to carry the
axle; according to the ordinary method the said bushes are riveted to the cheeks.
This Invention consists in forming the cheeks of iron which is rolled with a

page_text: thickened part of sufficient width to act as a bush for the axle. The expense of
riveting the bush to the cheek is thus obviated, and the bush is much firmer when
formed in the same piece with the cheek than when riveted thereto.
The hole for the axle is punched out of the thickened part of each cheek.
Having thus stated the nature of my said Invention I will now proceed more
particularly to describe the manner of performing the same with reference to the
accompanying Drawing and to the letters of reference marked thereon.
DESCRIPTION OF THE DRAWING.
The Drawing is made full size; the same letters of reference occurring upon any
of the views indicate corresponding parts.
Figure 1 is a side elevation of a wrought-iron axle pulley constructed according
to this Invention; Figure 2 is an end elevation of Figure 1; and Figure 3 is a view
looking at the under side of Figure 1.
A, A, are the cheeks, and B, B, are the thickened parts which are rolled upon the
iron forming the said cheeks; the holes C, C, for the axle bearings are punched out
of the thickened parts B, B. The parts B, B, have preferably inclined sides, as
shewn, so as the more readily to leave the rolls during their manufacture, and also to
give a more uniform strength to the cheek. The iron for the said cheeks is preferably
rolled in strips containing the thickened part down the length thereof; the pieces
for the cheeks are then sheared off transversely. I make no claim however for the
method of rolling the iron, which may if convenient be rolled with thickened parts
across the strip, or in any manner adapted for analogous purposes, as will be readily
understood by persons skilled in the rolling of iron.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that I claim as my
Invention, the manufacture of the side pieces or cheeks of wrought-iron axle pullies
from iron having a thickened part or parts rolled thereupon for the bushes of the
axles, substantially as herein described and shewn upon the Drawing; and I declare
that I do not limit myself to the exact configuration as shewn, as such is not necessary
to the utility of my Invention.
In witness whereof, I, the said James Henry Butler, have hereunto set my
hand and seal, this Fifth day of June, in the year of our Lord One thousand
cight hundred and seventy-seven.
