I, THOMAS WALTER HARDING of the Tower Works, Globe Road, Leeds, Engineer
do hereby declare the nature of this invention to be as follows:
My invention consists in novel and useful methods of fixing hardened steel hooks
into frames for holding pile and other fabrics.-The steel hooks I use are either in
the form of staples or single teeth, but in either case the hook has been turned & has
received its final shape before being hardened. The hooks are fitted into plates of
metal, preferably of iron or steel, in which transverse grooves have been cut, to
receive the body of the hook, and longitudinal grooves, to receive the crown.
Where single hooks are used, a row of holes may replace the longitudinal grooves.-
The grooves are cut in the solid metal by milling cutters or otherwise.
The hooks having been fitted into the grooves made to receive them, the plate is
rivetted or screwed to the side of the frame.
If it be preferred, the grooves may be cut in the frame itself, and the hooks
secured in their places by a thin plate of steel or other metal screwed or rivetted
over them.
This system permits the use in a perfectly secure and rigid way, of hardened steel
hooks instead of the soft points hitherto used & which are bent to the required form
of hook after being fixed into the plate or the frame.
Instead of plates of metal in which the grooves have been produced by cutting
them out of the solid metal-plates may be cast in brass or malleable iron or other
suitable metal with moulded grooves to receive the teeth.

page_text: I, THOMAS WALTER HARDING of the Tower Works, Leeds, in the County of York,
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 :-
My invention consists in novel and useful methods of fixing hardened steel hooks
into frames for holding pile and other fabrics.
Fig. 6 shews the usual form of frame end. The steel hooks I use are either in the
form of staples or single teeth; but in either case the hook has been turned and has
received its final shape before being hardened. Fig. 1 shews my hardened double
steel hook A A being the shanks and B the head or crown of the hook. Fig. 2 and 3
shew convenient forms of single hooks. A is the shank and B the head. The hooks
are fitted into plates of metal-preferably of iron and steel-in which transverse
grooves have been cut to receive the body of the hook, & longitudinal grooves to
receive the crown. Fig. 4 shews a portion of a plate. CC are the transverse
grooves cut to receive the shanks of the hooks. DD is the longitudinal groove cut
to receive the head or crown B of the double hook, or the head B of the single hook.
At E one of the double hooks is shewn in position, and at F one of the single hooks.
Where single hooks are used, a row of holes may replace the longitudinal grooves
as shewn at Fig. 5. The form of hook used in this case is that of Fig. 3, the
shank A of which lies in the transverse grooves C. C, and the head B fits into the
holes H H H.
The grooves are cut in the solid metal by milling cutters or otherwise. The books
having been fitted into the grooves made to receive them, the plate is rivetted or
screwed to the side of the frame and the hooks are held by the grooves C C, while
they are prevented from turning round by their heads being held in the longitudinal
groove D, or in the holes H H H.
In Fig. 6 these plates are shewn at A A A A applied to the inside of the frame.
If it he preferred, the grooves may be cut in the frame itself and the hooks secured
in their places by a thin plate of steel or other metal screwed or rivetted over them.
This system permits the use in a perfectly secure and rigid way of hardened steel
hooks instead of the soft points hitherto used and which are bent to the required form
of hook after being fixed into the plate or frame.
Instead of plates of metal in which the grooves bave been produced by cutting
them out of the solid metal, plates may be cast in brass or malleable iron or other
suitable metal with moulded grooves to receive the teeth.

page_text: 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. Fixing double or single hooks to frames for holding pile and other fabrics,
substantially as described and shewn.
2. The combination of double or single hooks with transverse and longitudinal
grooves substantially as described and shewn.
3. The combination of single hooks with transverse grooves and holes to receive the
heads substantially as described and shewn.
