page_text: COMPLETE SPECIFICATION.
New or Improved Cramp for Flooring, Joinery, and similar
Purposes.
I FREDERICK JOHN DOVE of 15 Studd Street Islington in the County of Middlesex
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:
That this invention consists of an arrangement of a form of Cramp by which
enormous power is obtained by the greatest ease and simplicity of adjustment in
connection with the laying af floor boards, joinery and similar purposes.
Also that the Cramp is placed between the joists and the pressure brought to bear
there instead of on the joists as is ordinarily the case-thus enabling the workman or
operator to "Side Screw" or "Side nail" the floor board without the Cramp being in
the way and impeding his operations.
And in order that this my Invention may be readily understood reference is made
to the Drawing left with my Provisional Specification and the figures and letters of
reference shown thereon-the same letters referring to like parts throughout.
Figure 1. General view of Cramp.
Figure 2. Plan of same.
Figure 3. End view of same.
Figure 4. Longitudinal Section.
A. Clip for Joist or Timber.
B. Lever and Screw.
C. Moveable Slides.
D. Shaped fulcrum or bridge.
E. Wedge.
F. Resisting or guiding plate.
G. G. and H. H. Bolts running throughout.
I. I. Slots in C to allow for expansion and contraction of cramp.
J. Screw hole for adjusting shield to prevent bruising.
The whole of the Cramp or parts thereof may be constructed of Iron, Steel or Brass.
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-
1st. The arrangement by which enormous power is obtained in the simplest manner
-much superior to other cramps extant.
2nd. The Cramp being so arranged as to be placed between the joists so that the
pressure is brought to bear there instead of on the joists-as is ordinarily the case
Thus enabling the operator or workman to side screw or "side nail" the floor
board without the Cramp being in the way and impeding his operations.
Dated this 7th day of March 1887.
