improvement are simplicity and cheapness of construction, and general efficiency
of the machine.
In the accompanying drawing-
Figure 1 is a rear elevation of my nail puller.
Figure 2 is a side elevation thereof with the parts in position for being driven upon
the nail.
Figure 3 is a like view of the same with the parts moved into the position for
biting the nail.
Figure 4 is a like view of the same with the jaws elevated, and-
Figure 5 is a view of the jaws.
A designates the frame having upon one side a handle B for convenience of
manipulation and bearing at its front the slide or rod 6, upon which is integrally
formed one of the holding jaws 7. The swinging jaw 8 is pivoted to said slide as
at 9 and has pivoted directly to its laterally extended arm 10 the lower end of the
lever C as at 11. The lever C, instead of being pivoted directly to the frame, is
pivoted to a link 12 as at 13, which link is pivoted to the frame A at 14. This
link is preferably double, that is, there is a link on each side of the lever. Upon the
outer end of the lever C is the sliding rammer D, which also serves as a handle for
said lever.
In use, the machine will be grasped by the handle B and rammer D and placed in
the position shown in Fig. 2, with the opened jaw directly over the nail to be pulled.
The rammer D is then moved up and down to drive the jaws into the wood sufficiently
to bite the nail. The lever is now pulled backwardly, at first swinging on the
fulcrum 14 as if the link 12 was a rigid part of said lever, thereby moving the
swinging jaw 8 and closing the jaws as shown in Fig. 3. Upon the further movement
of the lever, the rammer slips off from the upper end of the slide or rod 6, and the
lever has a combined movement, swinging on its pivot 13, and also on the pivot 14
at the lower end of the link carrying the jaws and slide or rod 6 upwardly into the
position shown in Fig. 4. The parts may be returned to their former position by
pushing the lever to its upright position and lifting the rammer far enough to bring
it over the upper end of the slide or rod 6.
By my improvements the machine is in a

light, simple and compact form, and
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
aleim is.

page_text: 1: The combination of the frame, the slide or rod 6 bearing the holding jaws,
the lever C pivoted at its lower end directly to the movable one of said jaws, and the
link 12 pivoted by one end to said lever at a point above its connection with said
jaw and the frame pivoted by its other end to a stationary support on the frame,
substantially as described and for the purpose specified.
2: The frame A having the handle B at one side thereof, the slide or rod 6
mounted on said frame and bearing the jaws the lever C connected with the frame
by a pivoted link and also pivoted to the swinging jaw, and the sliding rammer on
the outer end of said lever, adapted for striking the upper end of said slide or rod,
substantially as described and for the purpose specified.
