PROVISIONAL SPECIFICATION.
A Joiners' Bench Stop.
HENRY DAVIES The Castle, York; Mechanical Engineer; do hereby declare the
nature of this invention to be as follows:-
I take a piece of spring steel 74" long thick and 2" broad, I mark off 14 from
the end and in this space I drill and countersink three holes, 14 from the opposite
end I drill and countersink a hole, I also bevel this end from the under side & tooth
it, I then bend the plate so that when one end is screwed to the bench the opposite
end stands up. 1, the plate is then tempered and screwed to the bench as shown
at A, Fig. 1.
I then make a cast iron block of the fort shown in Fig. 2, the top of which is
3" long 2" wide and thick, the sides are 3" long thick and 14" deep. In the
centre of the top I form á hole of an oval shape long by " wide as denoted at B
Fig. 2. I also drill and countersink a hole at each end for screwing to the bench.
I drill a hole through the centre of each side, in these holes I fit. a
wrought iron roller 3" long and in diameter the centre of which is drilled and
tapped to take a screw as denoted at C Fig. 2. I sink this block in the bench-so
that the top is flush with the top of the bench and the oval shaped hole is under
the hole in the steel plate. I then insert a " screw through the steel plate and
cast iron block into the roller. The use of the roller is allow the head of the screw
to move back as the steel plate rises, and forward as it descends. A hole' is bored
through the bench under the screw and also under the bend of the steel plate to
allow dust to fall through: The advantages of this invention are, that it can be adjusted
to any desired height without loss of time, it cannot clog with dust, and also that it
grips and and holds the wood firmly.

COMPLETE SPECIFICATION
A Joiners' Bench Stop.
I, HENRY DAVIES formerly of The Castle, York but now of H.M. Prison
Chelmsford, Mechanical Engineer do hereby declare the nature of this invention
and in what manner tlie saine is to be perforined; to be particularly described and
ascertained in and by the following statement:-
This invention relates to a new or improved bench stop which can be easily and
readily adjusted to any desired height, and is not liable to become clogged with dust.
I will now particularly describe my invention making reference to the
accompanying drawings, in which :-
Figure 1 is a plan view of one form my invention may assume,

page_text: Figure 2 is a longitudinal section on line y-y of Figure 1, and
Figure 3 is a similar view of a modification.
Throughout the views similar parts are marked with like letters of reference.
The stop consists essentially of a springy plate A, preferably of steel, toothed or
roughened at its one end a, to adapt it to engage with the wood to be operated
upon. The other end of this plate is adapted to be firmly secured to the bench
top X in any suitable manner, a convenient method being by means of screws as
shown.
Immediately under the free end a of the plate A is a plate B adapted to lie flush
with and be secured to the bench top X. This plate B is furnished on its underside
with lugs b which are adapted to form bearings for a block or roller C. The head
of a screw D engages with a hole in the end a of the plate A, the shank passing
through,a slot in the plate B and then engaging with a screw threaded transverse
hole in the block or roller C.
It will thus be seen that by turning the screw D the free end a of the plate will
be raised or lowered, as desired, the tendency of the plate A as shown on the drawing
is to spring upward but it may be so formed as to have a tendency to spring
downwards in which case it will be evident that the head of the screw would be
shaped to suit the altered conditions:
As a modification, and which is also a simpler and cheaper construction, I may
dispense with the block or roller C and make the screw engage with a threaded hole
in the plate B (see Figure 3) in which case it is necessary to slot or enlarge the
hole in the end à of the plate A to allow for the screw D being always in a vertical
position.
Immediately under the bend or spring of the plate A and also under the screw D
I form holes in the bench top X to prevent dust and the like accumulating at
these points and interfering with the proper working of the device.
It will be evident that the device may be so arranged as to be self-contained, and
a convenient way of carrying out such a construction is to extend the plate B
sufficiently far to allow of the fixed end of the plate A being rivetted or otherwise
attached to it.
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 :-
.
(1) A joiners bench stop consisting essentially of a spring plate adapted to be fixed
to the bench at its one end and being toothed or roughened at its other end, and of a
screw threaded into a block or its equivalent and engaging with the free end of the
spring plate, as set forth.
(2) A joiners bench stop, constructed, arranged and adapted to be operated
substantially as herein before described and shown with reference to Figures 1 and 2
of the accompanying drawings.
(3) A joiners bench stop constructed arranged and adapted to be operated
substantially as hereinbefore described and shown with reference to Figure 3 of the
accompanying drawings.
