IMPROVEMENTS IN AND CONNECTED WITH SCREW-DRIVERS
Year: 1884

page_text: I CHARLES HAIGH of 26 Gell street Sheffield in the County of York, Clerk do
hereby declare the nature of my said Invention for "IMPROVEMENTS IN AND
CONNECTED WITH SCREW-DRIVERS" to be as follows:-
This invention consists in the construction of the blade of the screw-driver with
a hole, or slot, and in the employment therewith of a lever for the purpose of
turning the screw-driver.
The lever is cranked, or plain, and it is, or can be, slotted at one or both ends
thereof, to fit onto the blade of the screw-driver to turn it when the end of the
said lever cannot be inserted in the whole or slot in the blade. In using this
appliance the screw-driver is held firmly in position on the head of the screw with
one hand, and with the other hand the lever is inserted in the hole in the blade, or
fitted on the blade, and the screw-driver is thereby rotated.
I CHARLES HAIGH of 26 Gell Street, Sheffield, Yorkshire, Clerk, do hereby
declare the nature of my Invention for " IMPROVEMENTS IN AND CONNECTED WITH
SCREW DRIVERS" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This Invention consists in the construction of the Blade of the Screw Driver,
with a hole or slot, and in the employment therewith of a lever for the purpose of
turning the Screw Driver.
The lever is cranked or plain, and it is or can be slotted at one or both ends
thereof to fit onto the blade of the Screw Driver to turn it, when the end of the

page_text: said lever cannot be inserted in the hole or slot of the blade. In using this
appliance the Screw Driver is held firmly in position on the head of the screw
with one hand and with the other hand the lever is inserted in the hole in the
blade, or fitted on the blade and the screw Driver is thereby rotated.
The accompanying Drawings illustrate my Invention as applied to screw Drivers,
figure 1 represents the blade of an ordinary screw driver; A being the point which
is inserted into the scrow head and B the tang which is driven into the handle,
C is a rectangular slot or hole made in the blade.
Figure 2. represents a lever the end of which from D to E may be inserted in
the slot C (Figure 1) and used as described as an additional leverage for turning
the screw driver.
Figure 3 is an another form of lever which may be slotted at one or both ends
as shewn at F. G. the length and width of this slot corresponds with the size of the
blade of the screw driver; this form of lever is used by placing it on to the blade
like a wrench,
Figure 4 is another form of lever which when being used the point H would be
inserted into a round hole I in the blade of the screw driver as shown in Figure 5.
Figure 6 represents another form of lever which may have a hole as shown at J
at one or both ends, the blade of the screw driver being put through the hole J
when the lever has to be used.
The shanks or handle parts of these levers may be round or square or any other
convenient form, they may, be made double or single ended, or they may be made
so as to combine two forms of application in one lever, thus a lever as illustrated
in Figure 2 could be made as shewn at one end, with the other end as illus-
trated F. G in Figure 3, and in like manner Figure 4 could be made as shown at
one end, with the other end as illustrated in Figures 3 and 6 and so on ;-and the
lever or any of them may be made of iron or steel or any other equivalent material.
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
•
Improvements in and connected with screw Drivers by which an additional
leverage can be brought to bear in turning them either by inserting a lever into
a hole or slot made in the blade of the screw driver or by using a fork or slotted
lever which can be slipped onto the blade of the screw driver and used like
a spanner or wrench substantially in the manner herein before described.
The blade or blades of the screw driver and the lever or levers used therewith
constructed, as and for the purposes set forth and described and illustrated by the
six figures in the accompanying drawing.
