THE DAVID KIMBERLEY AND SONS TOOL MANUFACTURING COMPANY, LIMITED,
Highgate Tool Works, Emily Street, Birmingham, and WILLIAM KIMBERLEY,
Manufacturer, of the same address, do hereby declare the nature of this invention
to be as follows:
My invention has reference to improvements in cramps used by carpenters in
laying the boards of floors in buildings and generally known in the tool trade
as the Kimberley cramp or the Kimberley floor cramp. The foot of the cramp (or
part which presses against the board to be cramped) has usually a flat vertical
face. In the improvement to which this invention has reference: to the top of
this foot is cast or otherwise affixed an overhanging projection or projections so
made that when the lower part of the foot of the cramp is placed against the
vertical face of the board the overhanging projections shall fall on the uppermost
surface of the board so that no fitting or placing is required as an instantaneous
and automatic fitting is obtained and the workman can at once proceed to apply
the required pressure to cramp up the boards.
Dated this 28th day of December, 1899, and sealed with the common seal of
the Company in our presence.

Our invention has reference to improvements in cramps used by carpenters in
laying the boards of floors in buildings and which is generally known in the tool
trade as the Kimberley cramp or the Kimberley floor cramp. The foot of the

page_text: cramp (or part of the cramp which presses against the board to be cramped) has
usually a flat vertical face.
In the improvement to which this invention has reference, to the upper part
of this foot is cast or otherwise affixed an overhanging projection or projections
so made that when the lower part of the foot of the cramp is placed against the
vertical face of the board the overhanging projections shall fall on the uppermost
surface of the board so that no fitting or placing is required as an instantaneous
and automatic fitting is obtained and the workman can at once proceed to apply
the required pressure to cramp up the board.
We will now proceed to describe the invention with reference to the accom-
panying one sheet of drawings in which
Fig. 1 shows a perspective view of a Kimberleys flooring cramp in which the foot
of the cramp A has overhanging projections B, B, B as before described.
Fig. 2 is a perspective view of the foot of the cramp as in use; showing the
overhanging projections B. B, B as resting on the plank to be cramped marked C.
In Fig. 2 as in Fig. 1 the foot of the cramp is marked A.
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) In floor and other cramps the plate or plates projection or projections over-
hanging the vertical face of the foot and falling on the uppermost surface of the
board as herein set forth and described.
(2) In floor and other cramps the foot of the cramp with overhanging plate
plates projection or projections as herein set forth and described.
