We ORLANDO ETHELBERT LEWIS of 104 High Street Boston Massachusetts
United States of America but at present residing at the Charing Cross Hotel in the
County of Middlesex Gentleman and ALBERT EDWARD STIRCKLER late of Boston
aforesaid but at present of Ram Hotel Northampton in the County of Northampton
Engineer do hereby declare the nature of this invention to be as follows
This Invention has for its object to provide a simple and convenient tack driver
intended more particularly to be employed for shoe lasting, but which may be
employed for other purposes, and intended to be used in connection with tack strips
consisting of a series of tacks connected together by their heads and arranged at
regular intervals apart from one another such for example as described in the Specifi-
cation to Letters Patent dated January 25th 1887 No. 1160.
The improved apparatus consists of a combination and arrangement of parts
hereinafter described whereby the strip of tacks is fed forward so as to bring the
tacks successively into position to be separated from the strip and driven into the
article being operated on.
In a hollow siem or socket which may constitute the handle of the apparatus is fitted
to slide a plunger or punch stock, carrying at its lower end a punch or driver proper
This punch stock is provided with a cam groove in which works a friction bowl
carried on the upper end of a lever mounted on a stud in the interior of the stem so
that by the up and down motions of the punch stock an oscillating motion is given to
the said lever-The lower end of this lever is provided with a tooth or projection
engaging a feed plate or block fitted to slide transversely, or in the direction of feed,
through the lower end of the stem. This feed plate or block is provided with a spring
catch or pawl which engages the end tack of the strip, so that when the feed block is
moved in the direction of feed it carries the strip of tacks forward and brings the
end tack into engagement with a projection which holds it in position to be severed
from the strip and to be driven into the article other spring plates or levers being
arranged at the opposite sides of the spring pawl to ensure the tack strip being
properly placed and retained in position. When the feed plate is moved in the

page_text: backward direction the projection engaging the end tack will prevent the strip from
moving back with it whilst the spring pawl which had previously fed the strip forward will
yield and pass beneath the tack next to the end one and engage therewith in readiness
to feed the strip forward at the next operation of the punchstock. In commencing to
use the improved apparatus a tack strip is inserted by hand through a suitable guiding
trough or channel until the end tack passes over the spring pawl hereinbefore
described after which the strip will be fed forward step by step at each up-stroke of
the punch which upstrokes are effected by a spring interposed between the head of the
punch stock and a shoulder provided in the hollow stem in which the punch slides.
The end tack of the strip being in the position described the punch is forced down
by hand or otherwise whereupon the end of the said punch will come into contact
with the head of the end tack and by pressing the part which connects the said tack
with the next one of the series, against a cutting edge of a punch guide or stationary
die fitted in the hollow stem, the end tack will be severed from the strip and by the
continued descent of the punch the severed tack will be driven through a guiding
passage in a nozzle fitted to the lower end of the stem and out therefrom into the
article being operated on.
Upon removing the pressure from the punch stock the said stock and punch will be
raised by the spring hereinbefore described and the cam slot in the stock by, acting on
the oscillating feed lever will effect the feeding forward of the strip so as to bring the
next tack into position to be operated on these operations being repeated with each
motion of the punch.
The guiding holes and passages in which the punch works are preferably made in
removable bush pieces so that when the holes or guides become worn or injured the
bushes may be removed and fresh ones substituted therefor.
The stem or hollow socket is preferably divided longitudnially into two parts and
connected together by screws bolts and nuts.

page_text: We ORLANDO ETHELBERT LEWIS of 104 High Street Boston Massachusetts United
States of America but at present residing at the Charing Cross Hotel in the County
of Middlesex Gentleman and ALBERT EDWARD STIRCKLER late of Boston aforesaid
but at present of 8 St. Giles Terrace, Northampton in the County of Northampton
Engineer 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 has for its object to provide a simple and convenient tack driver for
driving tacks expeditiously the said driver being intended more particularly to be
employed for boot and shoc lasting, but it may be employed for other purposes, to
which it is or may be applicable. It is intended to be used for driving tacks which
are put into the driver in strips consisting of a series of tacks connected together by
their heads and arranged at regular intervals apart from one another such for example as
are described in the Specification of Letters Patent No. 1160 dated January 25th 1887.
The improved apparatus consists of a combination and arrangement of parts herein-
after described whereby the strip of tacks is fed forward so as to bring the tacks
successively into position to be separated from the strip and driven into the article
being operated on.
Figures 1 and 2 of the accompanying drawings are vertical sections at right angles
to each other and Figure 3 is a plan of a tack driver constructed according to this
Invention. Figures 4 to 8 represent details as hereinafter described.
C
A is a hollow stem or socket made of a convenient shape and size to be grasped by
the hand and preferably divided longitudinally into two parts for facility of access to
the interior the said parts being connected together by screw bolts and nuts a. Within
this socket or handle is fitted to slide a plunger or punch stock B carrying at its lower
end a punch or driver proper b. In one side of the punch stock is a cam groove 62
in which works a friction bowl c carried on the upper end of a lever C which is fitted
to oscillate on a stud c² in the interior of the stem A so that by the up and down motions
of the punch stock B an oscillating motion is given to the said lever. The lower end
of this lever is provided with a tooth or projection engaging in a notch or recess d
in a feed plate or block D fitted to slide transversely, or in the direction of feed through
the lower end of the stem A. This feed plate or block which is shewn detached in
Figure 4 is provided with a spring catch or pawl d² which engages the end tack of
the strip so that when the feed block is moved in the direction of feed as shewn by
the arrow in Figure 1 it carries the strip of tacks forward and brings the end tack
into engagement with a projection d³ where other spring plates or levers (arranged
on opposite sides of the spring pawl (2) act upon the said end tack so as to press it
into a recesss e in a steel piece or die E (shewn detached in Figure 5) fitted in the
stem A opposite the feed block B. The end tack is there severed from the strip and
driven into the article as hereinafter described. When the feed plate or block D is
moved in the backward direction the end tack being engaged by the spring plates <* in
the recess e will prevent the strip of tacks from moving back with it whilst the spring
pawl d² will yield and pass beneath the tack next to the end one and engage there-
with in readiness to feed the strip forward at the next forward motion of the feed

page_text: block. In commencing to use the improved apparatus a tack strip.(a portion of which
is illustrated in Figure 6) is inserted by hand through the guiding trough or channel
until the end tack passes over the spring pawl d² and is pressed by the spring plates d
into the recess e after which the strip will be fed forward step by step at the com-
mencement of each down stroke of the punch the upstrokes of which punch are
effected by a spring F interposed between the head of the punch stock and a
shoulder provided in the hollow stem in which the punch slides. The guide trough
or channel is fitted to or formed on the nozzle K of the apparatus and is provided
with a widened entrance or mouth as shown in Figures 3 and 8 to facilitate the
insertion of the strip of tacks.
The end tack of the strip being in the position in the recess e as described the end
of the nozzle K is placed in position on the article to receive the tack and then the
punch stock B is forced down by striking the head whereupon the end of the
punch which is guided in its movement by a perforated block G (shewn detached in
Figure 7) will come into contact with the head of the end tack and by pressing the
part which connects the said tack with the next one of the series against the cutting
edge of the recess e in the piece or die E the end tack will be severed from the strip
and forced by the punch through a guiding passage k in the nozzle K and out there-
from into the article being operated on. At the commencement of the descent of the
punch stock B the portion 63 of the cam groove will through the friction bowl c
cause the lever C to turn on the stud c² and the feed block D to inove back or in the
reverse direction to that shewn by the arrow in Figure 1 the spring pawi d² yielding
and passing behind the tack next to the end one and engaging therewith in readiness
to feed it forward at the next forward motion of the feed block. The stock B with the
punch bis raised to its normal position by the spring F and just as it is about com-
pleting its upward motion the portion of the cam slot 2 by acting on the oscillating
feed lever C through the bowl e will cause the lever C to turn on the stud C2 so as to
move the block D forward and carry with it the strip of tacks and bring the next tack
into position to be operated on by the next descent of the punch. These operations
are repeated with each motion of the punch. By means of this instrument the
securing of the uppers to the inner soles of boots and shoes when lasting or other
tacking operations may be effected with great rapidity.
The guiding holes and passages through which the punch works are preferably made
in removable bush pieces so that when the holes or guides become worn or injured the
bushes may be removed and fresh ones be substituted therefor.
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. In a tack driver the combination with the reciprocatory punch or driver, of the
sliding feed bar or block D with its spring pawl d² and detents d for engaging the
tack strip, and the stationary piece or die E having a recess e into which the end tack
of the strip of tacks is inserted and held in position to be severed from the strip
substantially as herein before described with reference to the accompanying drawings.
2. The combination with the reciprocating punch, of the oscillating lever guide
channel feed block D and the piece or die E substantially as and for the purpose
herein before described with reference to the accompanying drawings.
3. The general construction combination and arrangement of parts constituting an
improved tack driver, for use in lasting boots or for other purposes, as hereinbefore
described and illustrated by the accompanying drawings.
