page_text: We, ALONZO HENRY HARRIMAN, Machinist, 10 Pine Street, and CHARLES BARTLETT
RING, Mechanic, residing at 7 Maine Street, both of Orono, in the County of Penobscot,
and State of Maine, United States of America, do hereby declare the nature of this
invention to be as follows:-
This invention relates to claw hammers such as are usually employed for driving
and drawing nails, and the object thereof is to provide an improved device of this
class which is simple in construction and operation, and which is designed for use
as a hammer, and also for drawing nails of all kinds and sizes, and for similar
purposes.
In the practice of our invention we provide a clawhammer of the usual form which
is provided at one side of the body thereof with a tubular socket into and through
which the handle is inserted, and said hammer is provided with the usual claws,
and said claws are cut out longitudinally of their inner surfaces, and mounted in the
spaces thus formed, are pivoted jaws.
The slot between the claws of the hammer is carried backwardly nearly to the
tubular socket, and through which the handle is passed, and said slot is curved to
correspond with the curve of the claws, and the pivoted jaws are wider at their
inner ends than at their forward ends, and the rear ends are also curved, and passing
transversely through the claws of the hammer and the rear ends of the pivoted jaws,
is a pivot pin.
The upper side of each of the pivoted jaws directly over the pivoted pin is
provided with a notch or recess, and secured to the tubular socket is a strong plate
spring the lower end of which enters said notches or recesses, and the object of said
spring is to hold the pivoted jaws so that the lower surfaces thereof, and the lower
surfaces of the claws will be in the same circular plane.
Placed between the rear ends of the pivoted jaws is a triangular wedge or block
through which the pivot pin also passes, and the object of this block is to hold the
pivoted jaws in their normal position, and to permit of the free use and movement
thereof.
The pivoted jaws are segmental or circular in form in cross section, and the inner
surfaces of the claws of the hammer are also circular in form in cross section, and
in the operation of the device, the pivoted jaws are caused to grasp the nail to be
drawn in the usual manner, and in the operation of the drawing the nail, the
said jaws will move downwardly slightly, this operation being similar to that of a
wedge, and said operation will cause said jaws to more securely grasp and hold a
nail.
The claws of the hammer are also provided centrally of their inner sides with
notches or recesses, and the pivoted jaws are provided with lugs or projections which
move in said notches or recesses, and in the operation of the device, these lugs or

page_text: projections will strike the lower walls of these notches or recesses, and prevent the
pivoted jaws from being depressed far enough to break the pivot pin, but said
notches or recesses and said lugs or projections are not absolutely necessary as the
form of the claws of the hammer, and of the pivoted jaws, may be so regulated that
when a nail is inserted between said jaws, they cannot be depressed far enough to
break the pivot pin.
The front ends of the pivoted jaws are inclined backwardly and upwardly, and the
point of the claws are provided with corresponding shoulders or projections, and this
construction prevents the jaws from being raised above the level of the claws of the
hammer.
The lower inner surfaces of the pivoted jaws are also preferably provided with
serrations or teeth, or said inner surfaces of said jaws may be roughened in any
desired manner, in order that they may be enabled to more securely grasp and hold
a nail, and our improved hammer is sunple in construction and operation, and well
adapted to accomplish the result for which it is intended.

We, ALONZO HENRY HARRIMAN, Machinist, of 10 Pine Street and CHARLES
BARTLETT KING, Mechanic, of 7 Maine Street both residing at Orono, in the County
of Penobscot, and State of Maine, United States of America, 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:-
This invention relates to claw hammers such as are usually employed for drawing
nails, and the object thereof is to provide an improved device of this class which
inay be successively used in drawing nails of all kinds and sizes, and also small bolts,
and for similar purposes; and with this and other objects in view, the invention
consists in the construction, combination and arrangement of parts hereinafter
described and claimed.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which :-
Fig. 1, is a sectional side view of our improved claw hammer;
Fig. 2, a plan view thereof, the handle being shown in section; and,
Fig. 3, a section on the line 3, 3, of Fig. 2.
In the drawing forming part of this specification, the separate parts of our
improvement are designated by the same. numerals of reference. in each of the
views, and in the practice of our invention. we provide a claw hammer 5, of the
usual form which is provided at one side of the body thereof with a tubular socket
as 6, into and through which the handle 7, is inserted..
The hammer. 5, is provided with the usual claws 8, and in said drawing the
claws 8, are cut out longitudinally of their inner surfaces as shown at 9, and
mounted in the longitudinal spaces thus formed, are supplemental or pivoted,
jaws 10.
The slot between the claws 8, is carried backwardly near to the. tubular socket 6,
through which the handle 7, passes, and said slot is curved as shown at 11, and the

page_text: supplemental or pivoted jaws 10, are wider at their rear ends than at their forward
ends, and the rear ends thereof are also curved as shown at 12, and passing
transversely through the claws 8, and the rear ends of the supplemental or pivoted
jaws 10, is a pivot pin 13.
The upper side of each of the supplemental jaws 10, directly over the pivot pin 13,
is provided with a notch or recess 14, and secured to the tubular socket 6, is a
strong plate spring 15, the lower end of which enters the said notches or recesses,
and the object of the spring 15, is to hold the jaws 10, so that the lower surfaces
thereof, and the lower surfaces of the claws 8, will be in the same circular plane
as shown in Fig. 3.
Placed between the rear ends of the jaws 10, is a triangular block 16, through
which the pivot pin 13, also passes, and the object of this block is to hold the
jaws 10, in their normal position, and to permit of the free use and movement
thereof.
The jaws 10, are segmental or circular in form in cross section, as shown in Fig. 3,
and the inner surfaces of the claws 8, are also circular in form in cross section,
and in the operation of the device, the jaws 10, are caused to grasp a nail to be
drawn in the usual manner, and in the operation of drawing a nail the said jaws 10,
will move downwardly slightly, this operation being similar to that of a wedge, and
said operation will cause said jaws to more securely grasp and hold a nail, and in
Fig. 1, one of said jaws is shown in a slightly depressed position, so as to illustrate
this operation.
The claws 8, are also provided centrally of the inner side thereof with notches
or recesses 17, and the jaws 10, are provided with lugs or projections 18, which
move in said notches or recesses, and in the operation of the device, these lugs or
projections will strike the lower walls of said notches or recesses, and prevent the
jaws from being depressed, far enough to break the pivot pin 13.
It will be understood however, that said notches or recesses and the said lugs
or projections are not absolutely necessary, as the form of the claws 8, and of the
jaws 10, may be so regulated that when a nail is inserted between said jaws they
cannot be depressed far enough to break the pivot pin 13.
The front ends of the jaws 10, are inclined backwardly and upwardly as shown
at 19, and the points of the claws 8, are provided with corresponding shoulders or
projections 20, and this construction prevents the jaws 10, from being raised above
the level of the claws 8.
The lower inner surfaces of the jaws 10, may also be provided with serrations or
teeth if desired, or said inner surfaces of said jaws may be roughened in any
desired manner, but this construction forms no part of the invention, and, may or
may not be employed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A claw hammer the claws of which are cut away on their inner surfaces and
provided with supplemental pivoted jaws, said jaws being pivoted between said claws
at their rear ends, and said jaws being provided in their upper sides with notches or
recesses, and a spring which is secured to the socket of the hammer through which
the handle is inserted, and which projects into said notches or recesses, substantially
as shown and described.
2. A claw hammer the claws of which are cut away on their inner surfaces and
provided with supplemental pivoted jaws, said jaws being pivoted between said claws
at their rear ends, and said-jaws being provided in their upper sides with notches or
recesses, and a spring which is secured to the socket of the hammer through which
the handle is inserted, and which projects into said notches or recesses, said jaws
being also separated at their pivoted ends by a block through which the pivot
pin passes, and the inner surfaces of said claws being curved inwardly and down-

page_text: wardly, and said jaws being correspondingly formed, substantially
described.
