Year: 1881

page_text: LETTERS PATENT to William Frederick Lotz, of 20, Barbican, London, E.C.,
for an Invention of "IMPROVEMENTS IN APPARATUS FOR BINDING OR
SECURING TOGETHER SHEETS OR PIECES OF PAPER OR OTHER MATERIAL BY
MEANS OF METAL STAPLES OR FASTENERS." A communication from abroad
by George Washington McGill, of the City and State of New York, United
States of America.
PROVISIONAL SPECIFICATION left by the said William Frederick Lotz at
the Office of the Commissioners of Patents on the 31st December 1881.
WILLIAM FREDERICK LOTZ of 20 Barbican London E.C. "IMPROVEMENTS IN
APPARATUS FOR BINDING OR SECURING TOGETHER SHEETS, OR PIECES OF PAPER,
OR OTHER MATERIAL, BY MEANS OF METAL STAPLES OR FASTENERS."
A com-
munication from abroad by George Washington McGill of the City and State of
New York United States of America.
The object of the said Invention is to provide efficient and simple means whereby
the leaves of pamphlets, or books, or sheets, or pieces of paper, card, leather, cloth,
or other material may be expeditiously or firmly bound or fastened together. The
present Invention is designed partly to improve the apparatus described in the
Specifications of former Letters Patent dated 25th February A.D. 1879 No. 756,
and 10th September A.D. 1880 No 3601 and one important improvement consists
in providing special mechanism hereinafter described for automatically feeding
forward to the plunger the staples which are held in a receptacle specially provided
for the purpose. A special feature of the present Invention is a coiled spring (such as
an ordinary clock-spring) fixed upon the upper front end of the press immediately
back of the plunger. Proper tension is given to this spring by means of a small
ratchet-wheel mounted at one end of a spindle or bar holding the said coiled spring
controlled by a catch upon which catch a spring of suitable shape is brought to
bear for the purpose of holding the same in position. At the other end of said
spindle or bar is a button for the purpose of adjusting the tension of said spring.
In this Invention the staple-pusher consists of an elongated metal bar lying upon
the staple-track and travelling in the groove or slot in the upper part of the press
described in my former Letters Patent. One end of this bar is provided with a
suitable pin or projection to permit the coiled spring in which there is a hole of
suitable size to be looked on to said elongated staple-pushing-bar, and at the end
of the coiled spring is a pin or bar to enable said spring to be manipulated.

the said William Frederick Lotz in the Great Seal Patent Office on the 30th
June 1882.
WILLIAM FREDERICK LOTZ of 20 Barbican London E.C. "IMPROVEMENTS IN
APPARATUS FOR BINDING OR SECURING TOGETHER SHEETS OR PIECES OF PAPER
OR OTHER MATERIAL BY MEANS OF METAL STAPLES OR FASTENERS." A com-
munication from abroad by George Washington McGill of the City and State of
New York United States of America.
This Invention relates to improvements in presses or apparatus used for
inserting metallic staples or fasteners in paper cloth, leather or the like, and
clinching the said staples or fasteners upon the paper or other material both the
insertion and clinching being effected by one and the same movement.
The object of the said Invention is to provide efficient and simple means
whereby the leaves of pamphlets, or books, or sheets, or pieces of paper, card, leather,
cloth, or other material may be expeditiously, and firmly bound or fastened
together.
The said Invention is designed partly to improve the apparatus described in the
Specifications of former Letters Patent dated 25th February-1879-No.-756-and-
10th September 1880 No. 3691 and one important improvement consists in
providing mechanism hereinafter described for automatically feeding forward to the
plunger the staples which are held in a receptacle provided for the purpose. A
special feature of the said Invention is a flexible coiled spring (such as an ordinary
clock-spring) fixed upon the upper front end of the press immediately back of the
plunger.
For the better explanation of the said Invention I refer to the accompanying
Drawings in which like letters designate like parts. Figure 1 is a side elevation
of the staple-press. Figure 2 is a plan thereof with the lever elevated. Figure 3
is a vertical section of the press. Figure 4 is a front elevation thereof.
The flexible coiled spring a Fig. 1 is fixed upon the upper front end of the press
immediately back of the plunger a' in said Figure. Proper tension is given to
said spring by means of a small ratchet-wheel b Fig. 2 mounted at one end of a
spindle or bar upon which said spring is coiled and which said ratchet-wheel is
controlled by a catch b' Figure 4. A spring of suitable shape is brought to bear
upon the catch b' for the purpose of holding the same in position. The button c
Figure 4 at the other end of said spindle or bar adjusts the tension of the aforesaid
spring a. The lower end of the spring which bears upon the catch b' bears upon a
projection which gives the said catch b¹ the necessary spring. The staple-pusher
consists of an elongated metal bar & lying upon the staple-track d and travelling
in the groove, or slot in the upper part of the press described in the former Letters
Patent herein before severally referred to. A bar d Figure 2 is fixed at the end
of the flexible spring a to enable said spring to be pulled forward and in said
spring and near the aforesaid bar, is a hole shown in Figure 2 to admit of said
spring being hooked, on to the staple-pushing device herein before described.
Having now fully described the nature of the said Invention as communicated
to me by my said correspondent and the manner in which the same is to be carried
into practice I claim the flexible spring acting directly upon the device, which

the staples substantially as, and for the purpose herein stated, and illustrated
in the accompanying Drawings.
In witness whereof I the said William Frederick Lotz have hereunto set my
hand, and seal, this Thirtieth day of June in the year of our Lord One
thousand eight hundred and eighty two.
WILLIAM FREDERICK LOTZ. (L.S.)
