Improvements in Lathes or Sleys for Looms.
I, JAMES CRESSWELL of 21 Shepley Street, Hyde, in the County of Chester,.
Machine Joiner, do hereby declare the nature of my said invention to be as
follows:-
29-
My improvements refer chiefly to the lathes or sleys of calico and similar looms,.
and have for their object to strengthen the top of the lathe or sley and prevent
its warping, and also to prevent the vibration or working loose of the reed by
the grooves into which it fits becoming worn or enlarged with the "beating up
movement, and my improvements consist in the use and application of strips of
metal or similar. hard and durable material, forming protectors, which I apply
to the edge of the working side of the lower groove, and to the edges of the
upper groove of the lathe. These strips are of square or rounded cross section,.
and are fixed in any suitable manner to the lathe, but preferably by screws.
screwing through holes formed at suitable distances apart in the strips.
By so protecting the edges of the grooves all vibration of the reed causing
flaws in the cloth is effectually checked, and the grooves are preserved from
wearing away; the top and bottom parts of the lathe (especially the top part).
being also strengthened and prevented getting out of shape by warping.
For the better adjusting of the strips in relation to the reed, or for compensating
for any slight wear in the metal the screw holes may be elongated.
In lieu of the metal strip for the lower groove, the working side of the groove
itself may be made of metal, but I prefer the strips in that they can be more:
readily applied to existing lathes.

Improvements in Lathes or Sleys for Looms.
I, JAMES CRESSWELL late of 21 Shepley Street, and now of 117 Great.
Norbury Street, Hyde, Manchester, Machine Joiner, 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:—
My improvements refer chiefly to the lathes or sleys of calico and similar looms,.
and have for their object to strengthen the top of the lathe or sley, and prevent
its warping, also to prevent the grooves into which the reed fits becoming worn
or enlarged with the "beating up" movement, and my improvements consist in the
use and application of strips of metal or similar hard and durable material, forming
protectors, which I apply to the edge of the working side of the lower or lathe
bottom groove, and to the edges of the upper or lathe top groove.

page_text: These strips are of square, or rounded cross section, and are fixed in any suitable
manner to the lathe, but preferably by screws screwing through holes formed at
suitable distances apart in the strips, and when applied said strips effectually
retain the original size & shape of the grooves.
And in order that my improvements may be more readily understood, and
carried into practical effect, I have hereunto annexed a sheet of drawings, and will
now proceed to describe the same with the figures and letters of reference marked
thereon.
Fig. 1 illustrates a transverse section (about half full size) of the "sley" or
"lathe" of a loom, with my improvements applied thereto.
Fig. 2 illustrates one of the aforesaid strips or protectors in plan.
(A) designates the top portion of the loom sley, and (B) the lower portion, with
reed (C) held between them by taking into longitudinal grooves formed therein as
illustrated. Owing to the to-and-fro work, or intermittent "beating up" of the
reed in the direction of the arrow and to the sley being made of wood, the rear
sides (D) of said grooves rapidly become worn away, and consequently the reed
vibrates, or works loose, and is the cause of bad weaving.
To remedy this defect I provide the aforesaid grooves with strips of metal (E),
as shewn in Fig. 1, running the whole length of the reed, and fixed by screws (F)
screwing through counter-sunk holes into the sley. These strips effectually do
service in preserving the original size, and shape of the grooves, and render the
sley more durable than heretofore, with the consequent advantages of the reed
being always held tightly in the grooves, and no thin places occuring in the cloth.
Moreover, the top and lower portions (A) and (B) of the sley (and particularly
the top portion) are greatly strengthened and prevented getting out of shape by
warping when fitted with my improved strips.
The transverse shape or section of my improved protectors may vary, but I
prefer it to be rounded. If desired the edge nearest the reed may be slightly
deeper than the outer edge, and form the entire side of the groove, but I have
found the section shewn in the drawing to be effective.
Having thus particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
The herein described "protectors," or strips of metal (or their equivalent) as,
and for the purposes set forth.
