Improvements in Floor and like Cramps.
LUKE HIGGINSON of the "Reliance Gate and Fencing Works," Walsall Street
Wolverhampton in the County of Stafford, Fencing Manufacturer, and JACOB
WALKER, of Worcester Street, Wolverhampton in the County of Stafford, Blacksmith,
do hereby declare the nature of this Invention to be as follows:-
The object of our invention is to produce a "Cramp," to facilitate the laying of
floors, and also for "Bench work."
In carrying out our Invention we proceed as follows.
We add to an ordinary "Floor" "Cramp," a "Lever and Ratchett Bolt," with
suitable "Foot"; the said Bolt travelling on "Revolving Bearings," thereby
"easing" the "friction," when propelling the "Boards."
Two holding Catches"; instead of one; as generally used in "Floor ""Cramps ";
which lock intermediate, by means of "Springs," one "Spring" to each "Catch,"
which holds the "Bolt" from going back.
These "Catches," locking intermediate, give the previllege of using "half a
tooth" of the "forcing Bolt," at a time. Previously, "Eccentric Grips," have been
made "solid." In our Invention, we make the "Eccentric Grips," hollow. By being
made "hollow," the "Eccentric Grips," facilitate the "biting" or "gripping," of the
"Joist," or any other "Work" of the kind to which they are applied. There are
two Springs, one to each "Eccentric Grip." The said "Springs" force the
"Eccentric Grips" against the "Joist," thus enabling the "Cramp" to be worked
upside down for "Match Boarding," and any other kind of "Work" to which a
"Floor Cramp," is applicable.

or and like Cramps.
LUKE HIGGINSON of the "Reliance" Gate and Fencing Works, Walsall Street,
Wolverhampton in the County of Stafford, Fencing Manufacturer, and JACOB
WALKER of Worcester Street, Wolverhampton in the County of Stafford, Blacksmith,
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 :-
Our Invention relates to Tools used by Carpenters, and Joiners, Builders, and,

page_text: Our object is to provide a handy, simple, and inexpensive Tool or Implement, for
tightly closing the Joints of Flooring Boards, Match Boarding, Doors, and other
kinds of Wood work, previous to nailing or otherwise securely fastening them down.
Our Invention is also applicable for Bench Work.
In carrying out our Invention we proceed as follows, namely:-
We add to an ordinary Floor Cramp, a "Lever," and "Ratchett" bolt, with suitable
"foot," the said "Bolt travelling on "Steel Ball" bearings, thereby easing the
friction when propelling the boards. On. each side of "lever" are two "Travelling
Studs," attached to the propelling bolt, sliding in "Slots" or "Grooves" which
prevents the operator from straining the "Cramp." Two "Holding Catches" (instead
of one as generally used in Floor Cramps,) which lock intermediate by means of Springs
which are catches themselves, which holds the bolt from going back. These " Catches
locking intermediate allow half a tooth of the "Trueing Bolt" to be used at a time.
Previously "Eccentric Grips" have been made solid. In our invention we make the
"Eccentric Grips," open; which by being so made, faciliate the "biting" or
gripping "of the "Joist," or any other work of the kind to which they are applied.
There are also "Two Springs," one to each "Eccentric Grip." The said springs
force the "Eccentric Grips" against the Joist, thus enabling the Cramp to be
worked upside down, for Match boarding, ceiling, and any other kind of work to
which a Floor Cramp is applicable.

This cramp is very Powerful and will work in the space of 6 inches, allowing all
boards to be fixed except the last.
Having now particularly described and ascertained the
nature of our
said invention and in what manner the same is to be performed, we declare that,
what we claim is.
1. The instantaneous action, as the moment the operator Pulls the lever, it causes
the Propelling bolt to act instantaneous.
2. The sliding bolt travelling on steel ball bearings easing the friction.
3. The Eccentric open made grips Propelled by springs, leaving cramp safe on
joist when not in use.
4. The travelling studs attached to the Propelling Bolt, sliding in "Slots" or
"Grooves" Preventing the operator from straining cramp.
5. The "Springs" for tightening "Grips" on Joist.
