COMPLETE SPECIFICATION.
An Interchangeable Shuttle-box Connected with Looms for
Weaving.
I, JOHN EDWARD PRESTWICH, of Farnworth near Bolton, Lancashire,
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 :-
The improvements relate to the shuttle-boxes of looms for weaving, and are
applicable to the batterns or lathes of looms which have been prepared with a
number of shuttle-boxes working in a slide or otherwise, or what are known as
drop-box looms, or multiple shuttle looms; and have for object to form an inter-
changeable shuttle-box, which will enable a loom to be readily converted from a
multiple box loom to a single shuttle-box loom.
The extra weight entailed, in a lathe fitted with drop-box or multiple shuttle
mechanisms, renders a loom of that class less able to meet the requirement of speed,
when it is desired to weave therein goods requiring only one shuttle, and, as modern
exigencies of trade render it necessary to weave different classes of goods in one
and the same loom, it becomes advisable to effect a transformation of this
character.
To accomplish such results and to effect my improvements, I construct a shuttle-
box of the description shown in the accompanying sheet of drawings, wherein
Fig. 1, is an elevation, and Fig. 2, a plan view.
a, a, is the back-board, provided with holes or slots, or both, for bolting or
attaching the same to the lathe sword and fixings, in lieu of the frame for carrying
the sheaf of sliding or drop boxes or other multiple boxes, the form of which is
well understood.
b, b, is a projecting sheet of metal bent into shape, and b, b¹, is a cover plate.
These, with the back board or plate, form a single fixed shuttle box, while c, c, is
the swell, and d, d, the spring therefor, as will be readily understood.
When it is desirable to interchange the shuttle-boxes, the one may be taken off,
and the other bolted on, or otherwise attached to the lathe sword and fixings, by
means of the same bolts or other means of attachment in both cases.
By which means a loom may, in a very short time, be converted from a drop box
or multiple shuttle loom to a fixed single box loom.
It will be apparent that, although one form of interchangeable box is herein
shown, as suitable to a certain build of loom, other forms, and variations in details
may be made for the same purpose, and to suit any particular build of drop box or
multiple shuttle loom, without departing from the peculiar character of the
invention.
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 1
claim is :-
An interchangeable single shuttle box, for drop-box or multiple box looms, which
will enable such looms to be readily converted from the one class to the other, of
the character, and for the purpose, and in manner, substantially as herein shown
and described.
