PROVISIONAL SPECIFICATION.
Improvements in and relating to Bench Vices.
I, CHARLES BENJAMIN EASTICK, of 71 Well Street, Hackney, in the County of
London do hereby declare the nature of this invention to be as follows:--
My improvements relate to bench screw vices and are intended for those vices
having two or more screws which act independently of each other.
This independent action is very disadvantagous and it is.the object of the pre-
sent invention to dispense with the independent action before reffered to.
In carrying out my invention I fix upon the end of one of the screws upon the
outside of the block a suitable cog wheel of any required pitch and diameter this
wheel gears with another of similar dimensions fastened to the said block by
means of a pin upon which it revolves and this second wheel in its turn gears with
the cog wheel at the end of the other screw to which it is attached.
It will thus be seen that upon the turning of the first mentioned screw by the
handle usually provided the power is transmitted by means of the intermediate
toothed wheel to the second screw which also turns in like manner to the former
and thus only the one action is required to operate the two screws.
The said cogs may be counter sunk in the travelling block if necessary and
covered with an outer portion of wood to be fastened thereto so as to keep the
said cogs free from dust and dirt. It will be obvious that if necessary more than
two screws can be worked in a similar manner with a suitable train of wheels
gearing with each other for the purpose required. By means of this invention
much time and trouble is saved while the amount of pressure on each screw is the
same.
As my improvements are capable of some slight modification without departing
from the principle of my invention I do not restrict myself to the precise form or
placement of the parts thereof.
Improvements in and relating to Bench Vices.
I CHARLES BENJAMIN EASTICK of 71 Well Street Hackney in the County of
London Printers Assistant, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My improvements relate to
for those vices having two or
This independent action
Bench Screw vices and the like, and are intended
ore screws which act independently of each other.
ng very disadvantageous, it is the object of the

page_text: present invention to dispense with the 'independent action as before referred to.
The Vices constructed according to this invention, are made of Wooden Blocks
and Screws, with Iron, or other metal Wheels, Pins, and Chains. The front
Block of these Vices are constructed to open and shut, by the Screws being fitted
with a fixed Toothed Wheel, in connection with intermediate Toothed Wheels.
Or by the Screws being fitted with a fixed Toothed Wheel connected by an
endless Chain.
...
(Sheet 2.) In carrying out my invention the end of each screw A is fitted with
a fixed toothed wheel B. then placed in front block C, then keyed D in; inter-
mediate toothed wheels.E, are then placed on flanged headed pins F, then the
pins are fixed at proportioned distances between the screws A A in the front
block C, uy the turning of a handle G placed in one of the screw heads A the
whole of the toothed wheels B. B. E. E. E. acting in unison causes the screws AA
revolve simultaneously either to open or shut the front block C.
Sheet 1. Or the end of each screw AA may be fitted with a fixed toothed
wheel BB connected by an endless chain C, thereby dispensing with the inter-
mediate toothed wheels E. E. E.
An endless eyeletted belt may be used in place of an endless chain C.
The wheels may be counter sunk in the front block, and an outer casing of wood
fastened thereon, so as to exclude dust and the like.
Or a counter sunk casing of wood may be fixed on the block over the wheels
to exclude dust and the like.
The pressure on each screw is equally the same.
Friction wheels may be used in place of toothed wheels.
Sheet 1. Figure 1. shows a double screw vice as fitted to a bench, and worked
by means of endless chain and toothed wheels.
Sheet 1. Figure 2. shows front view of same.
Sheet 1. Figure 3. shows top view of same.
Sheet 2. Figure 1. shows Front view of a double screw vice, fitted with inter-
mediate toothed wheels, and Pins.
Sheet 2. Figure 2. shows top view of vice, also a method of fixing Pins.
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. The principle of working the screws simultaneously, by the above method
of intermediate, toothed, or friction wheels.
2. Or by fixed toothed wheels connected by endless chain, or endless eyeletted
belt.
3. No limit to number of screws worked by above method of intermediate
toothed wheels, or by fixed toothed wheels connected by endless chain or endless
eyeletted belt.
