PROVISIONAL SPECIFICATION.
Improvements in Shuttle Drivers for Smallware Looms.
I, JOHN FRANCIS ASHTON, of 18, Heywood Grove, Brooklands, Cheshire, Engineer,
do hereby declare the nature of this invention to be as follows:-
The improvements relate to the shuttle drivers in smallware looms, and have for
object the prevention of the driving teeth or pegs working loose in the driving bar,
as is a common occurrence in practice.
To accomplish this and to effect my improvements, I form the driving teeth or
pegs with collars or other projections, in such manner that when the teeth are fitted
into the driving rod or bar, I am enabled to hold them in firm position by means of à
plate passing from end to end of the bar and screwed or bolted thereon; or it may
be by a series of short plates covering two teeth or more than two, and which plate or
plates has or have openings or slots therein to allow the teeth to pass through, but
will not allow the collars or projections so to pass. By which means the teeth are
prevented from drawing out of the bar, and are also held in position laterally.
The plate or plates may be of metal or wood and of any suitable shape, and the
teeth may be of similar character to those at present in use, or other convenient
forms may be employed without departing from the peculiar character of the inven-
tion, which mainly consists of fastening the teeth or pegs to the driving bar for
driving shuttles in smallware looms, by means of a plate or plates passing over
projections or collars formed on such teeth or pegs for the purpose.

COMPLETE SPECIFICATION
Improvements in Shuttle Drivers for Smallware Looms.
1, JOHN FRANCIS ASHTON, of 18 Heywood Grove, Brooklands, Cheshire, Engineer, 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:
The improvements relate to the shuttle drivers in smallware looms, and have for
object the prevention of the driving teeth or pegs working loose in the driving bar,
as is a common occurence in practice.
To accomplish this and to effect my improvements, I form the driving teeth or pegs
with collars or other projections, in such manner that when the teeth are fitted into
the driving rod or bar, I am enabled to hold them in firm position by means of a
plate passing from end to end of the bar and screwed or bolted thereon or thereto,
or it may be by a series of short plates covering two teeth or more than two, and which
plate or plates has or have openings or slots therein to allow the teeth to pass through,
but will not allow the collars or projections so to pass. By which means the teeth
are prevented from drawing out of the bar, and are also held in position laterally,
The plate or plates may be of metal or wood, and of any suitable shape, and the
teeth may be of similar character to those at present in use, or other convenient forms
may be employed without departing from the peculiar character of the invention,
which mainly consists of fastening the teeth or pegs to the driving bar for driving
shuttles in small ware looms, by means of a plate or plates passing over projections or
collars formed on such teeth or pegs for the purpose.
But that the improvements may he better understood, I will by the aid of the
accompanying drawings proceed more fully to describe means employed by me.

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1. represents a cross section of one form of apparatus arranged in accordance
with my improvements; and Fig. 2. a front elevation thereof, while Fig. 3. is a plan
view of the same.
The same letters indicate corresponding parts wherever they occur.
a. a. is the driver bar, and b. b. the driving teeth, which are shown held in position
by the plate or plates c. c.
The arrangement shewn has one plate or series of short plates attached direct to
the driver bar; but this may be varied somewhat and the same object attained by
leaving a space between such plate and the driver bar, and a second plate or series of
short plates f. f. may be added at or near the top of the driver teeth as shown; for the
purpose of strengthening the driver teeth. Both the plates or series of plates may be
attached by screws, bolts, pins or any other convenient means.
The driver bar a. a. may be in one piece or in spliced or other joined or partially
joined sections, or may be saw-gaited to prevent warping, or arranged in any other
convenient manner.
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 what I
claim is :-
1. In shuttle driving bars for smallware looms, the employment of a metal or other
plate or series of plates c. c. in conjunction with driving teeth or pegs for the
purpose and in manner substantially as shown and described.
2. In shuttle driving bars for smallware looms, the employment of a binding plate
or series of plates f. f. at or near the top of the driving teeth combined with the
plate or plates c. c. at or near the bottom thereof for the purpose and in manner
substantially as herein.shewn and described.
