HAYHURST Cramp Maker 16 Elles Street Burnley Lancashire. We do hereby declare
the nature of this invention to be as follows:-
In this branch of business a cramp is requisite for bringing the boards together
our improvement is in the mode of fixing the cramp to the joices or beams by a lever
which is fixed tight to the joice or beam by a scrue which works another leaver &
secures boath to the sides of the joices or beams-being secured the boards are braught
close together by the long leaver which will be shone more particular in our complet
Specification.
Fig. 3 is a cramp complete.
Fig. 2 is a spur or back leg, which is fixed on the swell marked V, on Fig. 3.
Fig. 4 is a clip marked B & is fixed on lever A. at the swell marked I.
Fig. 5 is a short lever marked F to, correspond with the long lever marked A
up to letter I. Letter E is a screw & works through lever F & works through the
clip B. D is a handle which works the screw E.
Fig. 6 is a bolt with a thread part way & marked C with a spring marked H & is
fixed through long lever between F & S. The Spiral Spring marked K is to keep
the levers pressed open & the thumb screw H is to regulate the two levers
according to the thickness of the joice. In order to work this cramp place it on the
joice leaning backwards, turn the handle D a few times round & it will press the
ends of the levers marked N into the sides of the joice to prevent the cramp from
slipping backwards. Then pull the long lever towards you placing the boards just
below the swell on the lever marked S. Let the leg marked L follow on the top of
the joice until the joints are closed, there it will rest until the boards are, secured.
Then turn the handle marked D a few times round & the cramp is at liberty again,

page_text: What we claim is the clip B & the screw E. & the mode it works the levers A & F
also the bolt C & its contents & the manner the cramp is secured to the joice by the
levers A & F at the ends marked N. These may be either he or she centres or a flat
or square surface.

WILLIAM BRACEWELL Blacksmith No. 100 Sandygate Burnley, WILLIAM HAYHURST
Cramp Maker 16 Elles Street Burnley. We 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 :-
Onr improvement is in the mode of fixing the cramp to the joice, or beam, by two
levers, which clips the joice, and made secure by a screw, which presses the lever ends
into the joice, thus preventing any slipping while the boards are brought close together,
as shown in our specification in full.
What we claim is a long and short lever fixed together by a clip and a bolt, at
one end of the short lever, also a screw, which works the levers in and out, securing
them to the joice, & thus holding the cramp firmer than any other in use. These
levers works on a centre, which may be either he or she centres.
The Provisional Drawings are used for the Complete Specifications.
Fig. 1 is a long crooked lever and marked A. Fig. 2 is a back leg or spur and
marked L. Fig. 3 is a cramp complete. Fig. 4 is a clip and screw, and handle and
screw, working through Lever F. Fig. 5. is a short lever F, with screw E working
through, and also shows handle D. Fig. 6, is a bolt screwed a portion up, and a wing
nut marked H. also a spiral spring marked K.
Letter A is a crooked lever, with a long handle, in order to get power to bring
the joints close.
B is a clip, and is secured to lever A at swell I.
C is a bolt passing through levers A & F, at the swell marked S. This swell also
prevents the boards from rising up, when they are being brought together.
D is a handle, fastened to screw E which turns the screw in or out of lever F.
By this means the ends of the levers A & F are pressed into the joices or beams
and shown at N,

page_text: E is a screw, and is worked by handle D through lever F, bringing the ends of
levers A and F in or out at pleasure, marked N at the end.
F is a short lever and corresponds with long lever A up to letter I. Letter H is a
thumb nut or wing nut which regulates the distance of levers A and F, according to
the thickness of joices or beams, and works on bolt C. J shows the swell on lever A,
were the bolt goes through.
K shows the spiral spring on bolt C, which keeps the levers A & F pressed open.
N shows the end of levers A & F and may either be he or she centres, or both, or have
spikes in. This end presses into the joices to prevent the levers from slipping, when
cramping the boards close up. L is a leg or spur, and fixed to swell V on lever A,
and follows up on the top of the joice or beam, to prevent the cramp from slipping
back, when the boards are being brought together. M shows the joices or beams
which the cramps work on.
Having now particularly described and ascertained, the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is
A screw, and the mode it is fixed and worked, also the manner the cramp is secured
to the joice or beam in manner and purposes as herein shown and described.
