PROVISIONAL SPECIFICATION.
An Improved Nail Driving Tool.
I, WILLIAM HENRY THOMPSON, The Lindens, Peterboro, in the County of
Northampton, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved tool for driving tacks and other nails with
greater facility than with a hammer.
In carrying out my invention I provide a driver sliding in a sleeve and acted
upon by a spring.
The driving end of the driver is preferably magnetized so that a tack or the like
will adhere thereto. The other end of the said driver is provided with a knob or
handle which is struck to operate the tool.
In using my improved tool the driver is moved so that its driving end is near to
or projecting through the end of the sleeve, the driver is then placed against a nail
which is thereby attracted and then the driver with the nail is allowed to be drawn
within the sleeve under the action of the spring, the tool is then placed upon the
spot into which the nail is to be driven and the knob struck to drive the said nail.

COMPLETE SPECIFICATION.
An Improved Nail Driving Tool.
I, WILLIAM HENRY THOMPSON, of 147, Queen Victoria Street, in the City of
London, Engineer, 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 :-
My invention relates to an improved tool for picking up and driving tacks and
other nails with greater facility than with a hammer.
In carrying out my invention I provide a driver sliding in a sleeve and having
its driving end magnetized so that a tack or the like will adhere thereto. The
other end of the said driver is provided with a knob or handle which is struck to
operate the tool. A spring is advantageously provided for normally retaining the
driver within the sleeve.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is an elevation of my improved tool; and,
Figure 2 an elevation partly in section :
Figure 3 is a view illustrating the method of using the tool.
a indicates the driver having its lower end b which forms the driving-head
magnetized and of greater diameter than the other part thereof, and having at its
upper end a knob c by means of which the driver may be operated. d is the sleeve
through which the driver slides, the said sleeve having one portion e of its length
adapted to fit the small part of the driver a and another part of its length in the
form of a socket to receive the driving-head b, the said socket being of such
depth that the driving-head b can slide some distance within the same, as shewn in
Figure 2.
g is the spring which surrounds the driver a the said spring being arranged

page_text: between the sleeve d and the knob c in such a manner that it normally tends to
retain the driving-head within the socket.
In using my improved tool the driver a is moved so that the head b is near to or
projecting out of the end of the sleeve; the head 6 is then placed against a tack
which, owing to the magnetization of the said head b, is attracted, and then the
driving-head, with the tack, is allowed to be drawn back within the sleeve under
the action of the spring; the said sleeve serving, in case the tack adheres to one
side of the driving-head, to move the said tack onto the bottom thereof, as shewn
in Figure 2 where h indicates the tack: the tool is then placed with the sleeve over
the spot into which the tack is to be driven and the knob c is then struck to drive
the tack, as shewn in Figure 3.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A nail-driving tool comprising a driver sliding through a sleeve or socket
and having one end magnetized and at the other end a knob by means of which
the driver can be operated, substantially as described.
2. In a nail-driving tool, the combination with the driver and the socket through
which the same slides, of a spring for normally retaining the driving-head of the
driver within the sleeve or socket, substantially as described.
3. The manufacture and use of the improved nail-driving tool hereinbefore
described and illustrated in the accompanying drawing.
