Cramp Maker I do hereby declare the nature of my invention for CRAMPS to be as
follows:-
In this class of work a cramp is required for bringing joints close and cramping,
framing and other work. Hitherto the loose shoe or sliding end has been secured
by a loose pin or wedge, or in some cases a spring catch worked loose on a pin.
My invention consists in a fast pin attached inside the sliding shoe with a spring
to on the top or bottom or both bottom & top edge of the bar in order to keep the
shoe from slipping when the fast pin is not in the sneck or hole which is drilled
or filed on the top edge of the bar made to receive the fast pin which prevents the
shoe from slipping Fig. 1 is a cramp complete. Fig. 2 is the sliding shoe &
represents a T bar. Fig. 3 is a sliding shoe for a flat bar. A is a flat bar and
shows a number of holes or suecks on the top edge for the pin marked D to drop
in to prevent the shoe from sliding back when they are screwing up. B shows
side view and front for a T bar. C shows side and front view for a flat bar.
E is the spring at the bottom, inside which presses against the bar, to keep the pin
in the hole or sneck. F shows a recess and is filled with india rubber. His a
square iron washer which presses against the india rubber and the top side of the
bar and helps to keep the end steady, when not in action. I is a rebbit through
the spring and bottom end of the shoe which fastens the spring, by placing these
springs & this fast pin the cramp is set in a deal less time than in any other way
having know particulary described and ascertained the nature of my said inven-
tion. I declare that what I claim is
A pin fastened inside of the slot in the shoe and the fast spring at the bottom
of the slot in the shoe and the india-rubber spring and loose washer which presses
on the top of the bar as herein shown & described.;

WILLIAM HAYHURST, Cramp Maker, 1 Catlow Street, Burnley, in the county of
Lancaster, I do hereby declare the nature of my invention for CRAMPS, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
In this class of work a cramp is requisite for bringing joints close, and cramping
framing, hitherto the loose shoe or sliding end as been secured by a loose pin or
wedge and in some cases by a spring catch worked loose on a pin.
My invention consists in a pin fastened inside the sliding shoe, and a spring fixed
on the opposite inside which presses against the edge of the bar in order to keep
the end or shoe from slipping when the cramp is in use or out of use.
In the top
edge of the bar there is a number of holes or nicks filed at equal distances in order
to receive the end of the fast pin and thus prevents the sliding shoe or end from
slipping or giving way when the cramp is in action.
Fig. 1, is a cramp complete. Fig. 2, shows the side
end. Fig. 3, shows the end view of the sliding shoe.
is fastened in the sliding shoe or end. Fig. 5, shows the spring which is fastened
inside the sliding shoe to prevent it from slipping.
view of the sliding shoe or
Fig. 4, shows the pin which
Letter A on fig. 1, is the cramp bar which can be either flat, square, or T section
with a number of holes or slots filed at equal distances on the top or bottom edge.
Letter B, is the sliding shoe or end which can be moved to various distances as
required. Letter C, is the corresponding end which also slides up and down the
bar to a certain distance according as the screw is worked in and out. Letter D
is a fast end where the screw works in. Letter E, is a screw which puts the
pressure on the work, and works in letter D, and works letter C up and down on
the bar A. Letter F is a handle or pin by which letter E is turned. Letter G.
on fig. 4, shows flat and side view of the pin which is fixed inside of letter B, and
is also shown on figure 2, fixed in. This here pin has a swell at the outer end
made to fit in the holes or slots made in letter A, fig. 1. This pin can either be
flat or round and can be fixed in the shoe flat or at any angle. Letter H, on fig. 5,
shows the flat and side view of the spring which presses against the edge of the.
bar to prevent the end B, from slipping, and is fixed inside, opposite the fast pin G,
and shown on fig. 2. By this simple mode of securing this sliding shoe it can be
moved much quicker and is firmer than any other way I know of.
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
The fast pin and the spring and the mode or manner, the same is fixed and
put to work in the manner and for purposes substantially as herein shown and
described.
