Improvements in Stapling Implements or Staple Fasteners."
I, HENRY FARWELL WHITE, residing at Number 833 River Street, Detroit,.
Michigan, United States of America, Secretary of the Michigan Malleable Iron.
Company, do hereby declare the nature of said invention for IMPROVEMENTS, IN
STAPLING IMPLEMENTS, to be as follows:-
My invention relates to certain new and useful improvements in and relating to
apparatus for inserting staples so called "Stapling Implement," and is designed as an
improvement on a like apparatus shown and described in Letters Patent of the
United States Number 391,799 of October 30th, 1888, issued to Osro P. Johnson.
My invention has for its object, greater simplicity, economy and efficiency in the
construction and operation of the apparatus, and consists chiefly in the construction.
combination and arrangements of parts.
In the apparatus embodied in the patent aforementioned the driving arm is made
separable from the jaw, and of a separate piece of metal, engaged upon the end of the
jaw by a screw, the end of the jaw being provided with a shoulder to prevent the
turning of the arm thereupon. Moreover the sliding head is constructed with an
elongated slot, which slot receives the head of the screw the screw head limiting the
movement of said sliding head upon the driving arm. I now propose to make said
arm integral with the driving jaw, and to hold the sliding head in place in a simpler
manner. Accordingly, the driving jaw and the clinching jaw of my improved stapling
implement has a jointed engagement, said jaws are constructed, essentially like those
shown in said patent except as hereinafter noted.
The clinching jaw is provided with a clinching recess. The driving jaw is provided
with a driving arm which is made "integral," with the jaw, and preferably of a
malleable casting. This does away entirely with the labor and the additional elements
of making the arm of a separate piece, drilling the same to receive a screw and
recessing the arm also to engage a shoulder on the jaw, as shown in the patent*
referred to. By dispensing with the screw, the shoulder, the recess and the separable
driving arm, and making the latter arm integral with the jaw, it is evident the
structure is very materially simplified and improved. And there is never any liability
of the arm becoming loosened in any degree.
The sliding head is flanged as before, to engage the lateral edges of the driving
arm, and to serve also, at the same time, as a retainer for the staple. The lateral
edges of the driving arm may project sufficiently from the jaw to permit the firmer.
engagement of the sliding head on said arm, and its free movement thereupon.
It will be observed in dispensing with the screw heretofore used to unite the arm
upon the jaw, I may also dispense with the elongated slot heretofore formed in said
sliding head. And this constitutes one of the features of my improvement, and
instead of limiting the movement of the sliding head by the screw head, engaging
with the respective extremities of said elongated slot, I now simply force downward,
or I bend over a portion of the upper extremity of the sliding head to form a flange
to limit the movement of the sliding head in one direction by striking against the
extremity of the jaw. A spring Learing upon the upper end of the sliding head will
sufficiently limit the movement thereof in the opposite direction, said spring serving:
moreover, to keep the said head in a normal position, and permitting the bead to yield
under pressure to drive the staple home.
In this manner the sliding head may be made solid and the said head is formed on
the arc of a circle, as is also the driving arm of the driving jaw.

Improvements in Stapling Implements or Staple Fasteners:
1, HENRY. FARWELL WHITE, of 833, River Street, Detroit, Michigan, United
States of America, Secretary of The Michigan Malleable Iron Company, 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 certain new and useful improvements in a Stapling
Implement, and is designed more particularly as an improvement on Letters Patent
of the United States of America, dated October 30th, 1888, and numbered 391,799;
granted to: Osro.P. Johnson, assignor, of his entire right; title and interest: therein:
to me.:
My present invention has for its object, greater simplicity, economy and efficiency
in the construction and operation of the device;.and consists of the construction,
combination and arrangements of parts hereinafter described and pointed out in the
claims, and more fully illustrated in the accompanying drawings in which-
Figure 1, is a side, elevation of the device; showing the jaws opened;
Figure 2, is a vertical, longitudinal section thereof showing the jaws closed; .
Figure: 3, is a separate view of the sliding head;
Figure 4, is a separate view of the end of one of the jaws provided, with the driving.
arm, and

Figurer, is a section through the end of the jaw provided with the driving arm, 2
and the sliding head engaged thereupon.
I carry out my invention as follows:
In the device embodied in the foregoing patent, the driving arm was made separable-
from the jaw, of a separate piece of metal, engaged upon the end of the jaw by a
screw, the end of the jaw being provided with, a shoulder to prevent the turning of 2
the arm thereupon. Moreover, the sliding head' was constructed with an elongated
slot,.,which slot received the head of the screw, the screw head limiting the movement.
of said, sliding head upon the driving arm. I now propose to. make said. arın integral
with the driving jaw, and to hold the sliding head in place in a simple manner.
Accordingly, A, represents the driving jaw, and, A¹, the clinching jaw of my improved a
stapling implement, having a jointed engagement at, a, said, jaws are constructed
essentially like those embodied in said patent, except as hereinafter noted.
The clinching jaw is provided with a clinching recess or groove, a. The driving,
jaw is provided, with a driving arm, A2, which, in this case, is madé integral, with the
jaw, and preferably of a malleable casting. This does away. entirely with the labor:
and the additional elements of making the arm of a separate piece, drilling the same
to receive.a, screw, and recessing, the arm also to engage a shoulder on the jaw, as
shown in the former patent referred to. By dispensing with the screw, the shoulder,
the recess and the separable driving arin, and making said arm integral. with the jaw,
it is evident the structure, is very materially simplified and improved; and there is
never any liability of the arm becoming loosened in any degree..
The sliding head is shown at, B, and is flanged as before, as shown at, b, b!, to
engage the lateral edges of the driving arm, and to serve also, at the same time, as
a. retainer for the staple, C. The lateral edges of the driving arm may project
sufficiently from the jaw, as shown for instance at, 2, Figure 4, to permit the firmner
engagement of the sliding head on said arm, and its free movement thereupon.
It will be observed that in dispensing with the screw heretofore used to unite the
arm upon the jaw, I, may also dispense with the elongated slot heretofore formed in
said sliding head.
And this constitutes one of the features of my improvement, and instead of limiting
the movement of the sliding head by the screw head, engaging with the respective
extremities: of. said elongated slot, I now simply force downward, or bend over a
portion of the upper extremity of the sliding lead to form a flange, 3, it is evident,

page_text: will limit the movement of the sliding head in one direction by striking against the
extremity of the jaw, as shown in Figures 2 and 5. A spring, D, bearing upon the
upper end of the sliding head, will sufficiently limit the movement of the sliding head,.
also in the opposite direction.
The spring serving, moreover, to keep the said head in the normal position
shown in Figure 1, and permitting the head to yield under pressure to drive the
staple home.
In this manner the sliding head may be made solid. It will be observed that
the said head is formed on the arc of a circle, as well as the driving arm also of the
driving jaw.
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-
First: The stapling implement herein described, consisting of jaws, A, A¹, one of
said jaws provided with an integral driving arm, A³, and a sliding head supported
upon said arm, substantially as set forth.
:
Second The stapling implement herein described, consisting of jaws, A, A', one of
said jaws provided with a driving arm, and a sliding head supported upon said arm
said head provided with a flange, b³, substantially as and for the purpose set forth.
Third: The stapling implement herein described, consisting of jaws, A, A¹, one of
said jaws provided with a driving arm made integral therewith, a sliding head
supported upon the driving arm, said head flanged at the sides to embrace the
lateral edges of the said arm and also flanged at its upper end to limit the move-
ment of the head in one direction, and a spring bearing on said head, substantially
as set forth.
