effect when the tappet-shaft has been moved through its re-
quired travel, and then mechanically and automatically re-
leases the said tappet-shaft preparatory to the next tappet
action. My invention, as aforesaid, is applicable to any
switch which is operated by a tappet action, and particularly
to switches employed in electrical traction, where the said
switches are to be operated mechanically by a tappet-arm
carried by or connected to a motor vehicle moving at various
speeds along a line of rails.

No. 12837.—2nd August, 1900.—UNITED SHOE-MACHINERY
COMPANY, of Paterson, New Jersey, United States of
America, a corporation organized under the laws of New
Jersey, and having its principal place of business at 11,
Lincoln Street, Boston, Massachusetts, United States of
America (assignee of Louis Amedée Casgrain, of Winchester,
Massachusetts aforesaid, Inventor. An improved fastening,
boot or shoe made thereby, method of making said fastening,
and machine for inserting same.

Description.—Heretofore, for uniting leather and other
material in the manufacture of boots and shoes and other
articles composed of leather, it has been common to unite
the material by means of fastenings presenting at one end
a head, and at the other end a point, and commonly the
said fastenings when made of metal have had their points
clinched at one side of the material. The machine de-
scribed is entirely novel, and has been especially devised to
make a new form of fastening which co-operates with and
holds together material in a novel manner, the material so
united by fastenings being flexible, more flexible than if
united by stitches or pegs, or any usual fastenings having
heads. The fastening formed and driven by this machine
has a head with a depending point, and when the fastening
is driven this depending point enters the stock, and the
head is seated, effectually preventing any further move-
ment of the fastening into the stock, and insuring a uniform
presentation of the heads. Also, the point of the fastening
is clinched on a horn and turned upward toward the
depending head, and this prevents any outward movement
of the fastening, and in this way we give to the fastening
formed and driven by this machine a double clinch—that is,
when the fastening is driven, both head and point are
clinched, and all movement of the fastening in either direc-
tion is prevented. Our novel machine contains a guide-way
through which the fastening-material is fed, it may be
automatically, for the desired length, or for a greater or less
distance according to the thickness of the material to be
united, and while the said fastening-material is held in
or at the end of said guide-way, said material is acted upon
by a shaper, which bends the material and defines the
length of the body or shank of the fastening, including its
point, and the fastening-material so bent is then acted upon
by a suitable shear or cutting-mechanism, which severs the
fastening-material preferably diagonally back of the bend
made by the shaper, leaving a blank consisting of a shank
and a tapered portion, to be subsequently bent to form a head
for the fastening. This blank, in its further treatment for
the production of a fastening, is moved to one side of the line
of feeding-movement of the wire, and a bender acts upon the
short end of the wire extended from the shank and bends it
over an anvil, thus completing the head and presenting a
novel fastening comprising a shank of the desired length and
a loop-shaped head having a short depending point extend-
ing at an angle to the shank. The fastening so formed may
then be removed from the anvil by imparting to the movable
cutter of the cutting-means and the shaper and bender a
further movement, the fastening being deposited in a driver-
passage preparatory to the descent of a driver to act upon
and drive it through a passage in a suitable nose- or foot-plate
adapted to bear upon the surface of the stock sustained in
any suitable manner, preferably by a horn. The fastening
while being driven from the nose- or foot-plate by the driver
is guided and directed in its passage into the stock by the
frictional contact of the loop-like head of the fastening with
the walls of the driver-passage, said walls retaining the
fastening in the condition of bending while being
driven. The stock will preferably have a channel to
receive the fastening, the lower end of the fastening being
clinched by striking the horn or work-support. The short
point depending from the head of the fastening enters for a
limited distance the upper surface of the stock. The wire of
which the fastening is made is preferably curved so that the
shank of the fastening presents a curve, and the point of the
shank is tapered and also slightly bevelled at one edge, said
curve and bevel being utilised to control the direction of
movement of the shank of the fastening as it is being driven

through the stock, the shank being so directed as to always
insure that its point may correctly enter the inner sole of the
shoe. A fastening having a head of the kind described may
be made of comparatively light material—that is, of a wire
much smaller in diameter than would be required to form
an upset head which would contact with the stock for a dis-
tance equal to the part spanned by the bent head of our
improved fastening, and so by reason of the shape of the
fastening and the manner in which it engages the stock it is
possible to separate the fastenings farther when being driven
than is the case with an ordinary fastening, thereby lessen-
ing the tendency to stiffen the sole, and yet the fastening
will hold the material firmly, the depending point of the
head aiding very materially in effecting this object.

No. 12838.—2nd August, 1900.—JOHN HERBERT WALKER,
of Mary Street West, Charters Towers, North Queensland,
Pianoforte-importer. A combined syringe, or injector and
reservoir.

Claims.—(1.) A syringe, injector, or the like, comprising a
cylinder having a plunger, the said cylinder being secured
at an inclination to a reservoir with which it is in com-
munication by an orifice, substantially as described.
(2.) A syringe, injector, or the like, comprising a
cylinder having a plunger and a conical reservoir, to the
upper part of which the said cylinder is secured at an
inclination, and which is in communication with the said
cylinder by an orifice adapted to be closed by the piston or
plunger when the latter is forced forwards, substantially as
described. (3.) The combination and arrangement of parts
forming the improved syringes, injectors, or the like described
