PROVISIONAL SPECIFICATION.
Improved Mechanism for Feeding Wire to Machinery, Chiefly
Designed for Use in the Manufacture of Umbrella and Parasol
Ribs and Stretchers.
I, WILLIAM CORDER, of Allison Street Works, Birmingham, in the county of
Warwick, Umbrella Rib Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improved mechanism for feeding wire to machinery chiefly
designed for use in the manufacture of umbrella and parasol ribs and stretchers,
but also applicable for use with other machines for cutting wire into lengths.
Hitherto the arrangements for drawing forward or feeding the wire, from which
is formed umbrella and parasol ribs and stretchers, have been faulty inasmuch as the
wire was not drawn forward in regular lengths and hence waste arose in cropping or
cutting the lengths. Stops could not be applied owing to breakages caused by inaccuracies
in the throw of the feeding rod, arising from various causes such as a variation in the
speed of the engine.
By my improved feed mechanism these defects are obviated as each rib and
stretcher is cut with precision thus obviating the waste that occurred in previous
methods.
My improvements consist in employing springs for effecting the to-and-fro move-
ment of the gripping block in combination with adjustable stop pins in the piercing
and cropping blocks.
In carrying out my invention, I provide the ordinary feed rod operated by the
usual disc, with a shoulder or stop near one end thereof, on or near which end I
attach a nut and lock nut acting as an adjustable shoulder or stop; the said rod,
which passes through the lever operating the gripper works between the above named
shoulder and the nut. On the rod and between its shoulders or stops and the lever
As the rod
are two springs of suitable strength one on each side of the lever.
advances the lever is pressed by one of the springs until it comes against the head of
the pin in the block of the travelling gripper, thereby causing the gripper to advance
until it comes into contact with an adjustable stop pin with which I provide the
piercing block. The wire is then gripped in the usual manner and drawn through
the cropping block by the spring on the rod pressing against the lever on the other
side until it comes against the head of the pin in the block of the travelling gripper
thereby causing the gripper to advance until it is stopped by an adjustable stop pin
with which I provide the cropping block.

Improved Mechanism for Feeding Wire to Machinery, Chiefly
Designed for Use in the Manufacture of Umbrella and Parasol
Ribs and Stretchers.
I, WILLIAM CORDER, of Allison Street Works, Birmingham, in the County of
Warwick, Umbrella Rib Manufacturer, 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 improved mechanism for feeding wire 10 machinery

page_text: chiefly designed for use in the manufacture of umbrella and parasol ribs and
stretchers, but also applicable for use with other machines for cutting wire into
lengths.
Hitherto the arrangements for drawing forward or feeding the wire from which
umbrella and parasol ribs and stretchers are formed have been faulty inasmuch as the
wire was not drawn forward in regular lengths and hence waste arose in cropping or
cutting the lengths. Stops could not be applied owing to breakages caused by
inaccuracies in the throw of the feeding rod arising from various causes such as a
variation in the speed of the engine.
By my improved feed mechanism these defects are obviated as each rib and
stretcher is cut with precision thus obviating the waste that has occurred in previous
methods.
My improvements consist in employing springs for effecting the to-and-fro move-
ment of the gripping block in combination with adjustable stop pins on the piercing
and cropping blocks.
In order to enable my invention to be fully understood I will describe how it can
be carried into practice by reference to the accompanying drawing, in which
Figure 1 is an elevation illustrating my improved mechanism suitable for use
for feeding wire to machinery for the manufacture of umbrella and parasol ribs
and stretchers.
Figures 2 and 3 are views of portions of the mechanism drawn to an enlarged
scale.
с
In carrying out my invention I provide the ordinary feed rod a operated by the
usual disc 6 with a shoulder or stop c near one end thereof, on or near which end I
attach a nut d and lock nut e acting as an adjustable shoulder or stop; the rod a
passes through the lever operating the gripper, and the lever (shown in detached
side view at Figure 2) works between the shoulder c and the nut d. On the rod a and
between its shoulders or stops c and d e and the lever fare two springs 9 and h of
suitable strength one on each side of the lever. As the rod a advances the lever fis
pressed by the spring g until it comes against the head of the pin jin the block k of the
travelling gripper (shown detached in side elevation of Figure 3) thereby causing the
gripper to advance until it comes into contact with an adjustable stop pin m with which I
provide the piercing block n. The wire a³, Figure 3, is then gripped in the usual manner
and pushed through the cropping block o by the spring on the rod a pressing
against the lever f thereby causing the gripper to take hold of the wire and to
advance until it is stopped by an adjustable stop pins with which I provide the
cropping block o.
I have described by way of example how my improved wire-feeding mechanism
can be employed in connection with machinery used in the manufacture of
umbrella and parasol ribs and stretchers. Its application for use with other
machines for cutting wire into lengths will be well understood without further
description it being obvious that the gripping device and stops can be modified to
suit different cases.
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. In mechanism for feeding wire to machinery the employment of springs arranged
upon a reciprocating rod and bearing upon a lever attached to and operating a device
for gripping and feeding the wire, adjustable stops being provided for determining
the extent of travel of the gripper, substantially as hereinbefore described and
illustrated in Figure 1 of the accompanying drawing.
2. In mechanism for feeding wire to machinery for use in the manufacture of
umbrella and parasol ribs and stretchers, the combination with a gripping block
of springs arranged upon the feeding rod and bearing upon a lever on the gripping
block and of adjustable stop pins on the piercing and cropping blocks for

page_text: the purpose and substantially as hereinbefore described and illustrated in the
accompanying drawing.
3. The improved mechanism for feeding wire to machinery for use in the manufacture
of umbrella and parasol ribs and stretchers herein before described and illustrated in
the accompanying drawing.
