PROVISIONAL SPECIFICATION.
Improvements in Screwing Appliances for Adjusting the Screw
Threads of Caps for Mail and Collinge's Čarriage and other
similar Axles.
.
We, WILLIAM HENRY WOODHEAD, and FRANK WOODHEAD, of Whitham's
Forge, Leeds, in the County of York, Axle and Spring Manufacturers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in screwing appliances for adjusting the
caps of mail and Collinge's carriage and other similar axles, and its object is to
provide a simple and handy appliance adapted to readily reduce a new cap to the
size required for any particular axle.
For this purpose we employ a divided stock one portion of which is extended to
form handles or levers and the other portion is hinged thereto at one end and the
other end is adjustably connected by a stud and thumb-screw. The aperture for
the cap is formed between the two portions and the internal periphery of this
aperture is provided with two or more segmental projections cut with a screw
thread the same pitch as the caps. A radial die or chaser of the same pitch is
also provided fitted in a suitable radial guide and provided with a tail screw for
adjustment.

We WILLIAM HENRY WOODHEAD, and FRANK WOODHEAD, of Whitham's
Forge, Leeds, in the County of York, Axle and Spring Manufacturers 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 improvements in screwing appliance for adjusting the

for the cap is formed between the two portions and the internal periphery of this
aperture is provided with two or more segmental projections cut with a screw
thread the same pitch as the caps. A radial die or chaser of the same pitch is
also provided fitted in a suitable radial guide and provided with a tail screw for
adjustment.
Reference is to be had to the accompanying sheet of drawings forming a part
of this Specification, in which similar letters of reference indicate corresponding
parts in each of the figures.
Figure 1, represents an elevation of our improved screwing appliance.
Figure 2, is also an elevation taken at right angles to Figure 1.

page_text: Figure 3, represents a section on the broken line a, b Figure 2 of the hinged
portion of the stock showing the said radial guide and chaser mounted therein.
The stock is divided longitudinally into the handle piece A and the hinged
piece B and the latter is hinged to the former at one end by the hinge C. The
other end of B is adjustable connected to A by the screw D fixed by the pin E in
a slot V formed in A. and the screwed end of D passes freely through the hole F
in. A and is provided with a thumb screw G. A radial guide H is formed in the
projection J on B and a chaser K is fitted therein which is free to be adjusted
longitudinally by the tail screw L but is prevented from lateral movement by the
piece M retained in position by the screws N and bearing against the inclined
side O of the chaser. The aperture R for the cap is provided with segmental
projections S, S, S, S cut with guide threads the same pitch as the chaser.
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
A screwing appliance for adjusting the screw threads of axle caps consisting of
a divided screwing stock having one part adjustably hinged to the other and a
radial chaser fitted therein, substantially as herein shown and described and
illustrated in the accompanying drawings.
Dated this 23rd day of October 1893.
