Improvements in Tools for Driving Lasting Tacks.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to hand-operated tools for driving lasting-tacks into
partially formed boots and shoes in the process of manufacture, the tool being of
the class in which the tacks are supplied from a reservoir, one at a time, to the
action of a driver to which power is manually applied.
The improved tool has a casing formed of one integral mass of cast metal. It
has a cylindrical lower portion, a reduced open-ended cylindrical upper portion,
and a central guiding portion, to which a raceway is secured, and on which a
feed-slide reciprocates.
The central portion is provided with a square longitudinal aperture, to receive
and guide the driver-bar which is provided at its lower end with a flange and at
its upper end with a driving-head secured thereto in any suitable way. The
driver is fixed in an aperture in the lower end of the driving bar, and is of a
cross-diameter adequate for driving a tack into a last.
The driver-bar is normally held in a raised position, by a spiral spring coiled
around it and abutting against a leather or other yielding washer under the head,
and against the bottom of the cylindrical upper portion of the casing. When the
bar is depressed, the spring is all contained within the said cylindrical upper
portion.
The lower end of the cylindrical lower portion of the casing is closed by a cap
held in place by screws. The cap has an upwardly extending boss, with an aper-
ture to receive the driver, and also has a downwardly extending throat-piece, with
a converging aperture leading through it in alignment with the driver aperture.
A tack-centering and retaining device, consisting of a ring with depending spring-
fingers, is held in place between the throat-piece and the cap, and acts to temporarily
hold the tack in the throat until engaged by the driver.
The reservoir for the tacks consists of a box or hopper formed of sheet metal,
with a top which has a movable door for the reception of the tacks. The hopper
has a reduced passage-way in its bottom, through which the tacks drop into a
receiver having side and end walls, and a bottom slanting toward a raceway, to
which it is secured, one of the end walls having a passage-way to permit the tacks
to slide down the latter.
The raceway consists of two slightly separated flat bars, each having a lower
inclined portion covered with a flat strip. Both the strip and the raceway are
secured to a plate, which in turn is bolted to a bracket on the casing. The hopper
for initially receiving tacks is supported on a frame with an open top and bottom,

page_text: which frame is cast upon the end of an arm bolted to the top of the bracket-sup-
ported plate by bolts.
The receiver for guiding the tacks into the raceway extends up into the frame
just mentioned and is enclosed in an overflow-receptacle suspended from the
said frame by spring-arms having apertures to receive studs extending outward
from the frame.
The raceway extends between a bar and a plate, both bolted to the casing. A
feed-slide is arranged to slide past the end of the raceway and between the bar
and plate, and the casing, and to receive the tack from the raceway and carry it
to a delivering-tube, which begins at one side of the raceway and terminates at the
lower end of the casing. It communicates by a duct with the driver aperture,
so that a tack delivered therein will be dropped into the centering device in the
throat.
The feed-slide for transferring the tacks one by one from the raceway to the
delivery tube is provided with a recess in its face to receive the shank of the tack
from the raceway, and this recess may be made to register with a recess in the
plate at the side of the raceway, which latter recess communicates with the
delivery-tube.
The feed-slide is likewise provided with two rearwardly projecting ears, which
extend into a transverse groove in the casing, and which lie on either side of a
cam formed on the driver-bar by cutting away a portion of the front face thereof.
The cam is of such a nature and shape that when the driver-bar is depressed, the
slide is moved so that its recess registers with the raceway, and so that when it is
raised the recess registers with the recess in the plate. Thus each time a tack
is driven into the last, a fresh tack is taken from the raceway by the transferring
mechanism and delivered to the centering device in the throat. The slide may
be adjusted relatively to the cam by means of screws.
A tool formed in accordance with the above description is simple in construction
and highly efficient in operation. It has but few parts, and they are not liable
to get out of order, or to be displaced, while it may be manufactured at a minimum
cost.
Improvements in Tools for Driving Lasting Tacks.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 relation to hand-operated tools for driving lasting-tacks into
partially formed boots and shoes in the process of manufacture, of the class in
which the tacks are supplied from a reservoir, one at a time, to the action of a
driver to which power is manually applied.
The invention consists of a tool of the character described, possessing those
features of construction and arrangement illustrated in the drawings, and now
to be described in detail and then set forth in the claims hereto annexed.
Reference is to be had to the accompanying drawings, forming a part of this
specification, in which like characters indicate like parts or features, as the case
may be, wherever they occur.

the reservoir being illustrated partially in section.
Figure 2 represents a central vertical longitudinal section through the tool, the
reservoir and raceway being broken off, for lack of space.
Figure 3 represents a plan view of the same.
Figure 4 represents a section on line 4-4, Figure 1.
Figure 5 represents a rear elevation of a portion of the tool, the raceway and
the rear plate being removed, for the purpose of showing the reciprocating feed-
slide which transfers the tacks, one at a time, from the raceway to the tube which
delivers them to the throat through which the driver reciprocates.
Figure 6 represents a cross-section on the line 6-6 'of Figure 1, showing the
feed-slide as registering with the delivering tube, into which it has fed a tack.
Figure 7 represents a similar section, but showing the slide as registering with
the raceway and as having received a tack therefrom.
Figure 8 represents a perspective view, showing in detail a portion of the
raceway and of the delivering tube and the feed-slide.
Figure 9 represents partial section on the line 9-9 of Figure 1, illustrating
the internal construction of the reservoir from which the raceway extends.
Referring to the drawing, the improved tool therein shown has a casing a formed
of one integral mass of cast metal. It has a cylindrical lower portion b, a reduced
open ended cylindrical upper portion c, and a central guiding portion , to which
the raceway is secured, and on which the feed-slide reciprocates, as I shall afterward
set forth.
The
The central portion is provided with a square through-aperture, to receive and
guide the driver-bar e, which is provided at its lower end with a flange f and at
its upper end with a driving-head y secured thereto in any suitable way.
driver his set into an aperture in the lower end of the bar e, and is of a cross-
diameter adequate to drive a tack into a last.
When
The driver-bar is normally held in a raised position by a spiral spring coiled
around it and abutting against a leather or other yielding washer under the
head g, and against the bottom of the cylindrical portion c of the casing.
the bar is depressed, the spring is all contained within the said cylindrical
portion c.
The lower end of the portion b of the casing is closed by a cap k held in place by
screws. The cap has an upwardly extending boss, with an aperture m to receive
the driver, and also has a downwardly extending throat-piece n with a converging
aperture leading therethrough in alinement with the aperture m. A tack-centering
and retaining device, consisting of a ring o with depending spring-fingers 2, is held
in place between the throat-piece and the cap, as shown in Figure 2, and acts
to temporarily hold the tack in the throat until engaged by the driver.
The reservoir for the tacks consists of a box or hopper q formed of sheet-metal,
with a top which has a movable door r for the reception of the tacks. The hopper
has a reduced passage-way in its bottom, through which the tacks drop into a
receiver having side and end walls and a bottom slanting toward a raceway t,
to which it is secured, one of the end walls having a passage-way to permit the
tacks to slide down the latter.
The raceway consists of two slightly separated flat bars, each having a lower
inclined portion covered with a flat strip u. Both the strip and the raceway are
secured to a plate r, which in turn is bolted to a bracket on the casing. The
hopper for initially receiving tacks is supported on a frame we with an open top
and bottom, which frame is cast upon the end of an arm bolted to the top of the
plate by bolts y.
The receiver for guiding the tacks into the raceway extends up into the frame wc,
and is enclosed in an overflow-receptacle y' suspended from the frame w by spring-
arms z having apertured to receive studs extending out from the frame, as indicated
by broken lines in Figure 1,

page_text: The raceway extends between a bar a¹ and a plate 6', both bolted to the casing,
as shown in Figures 6 and 7.
A feed-slide is arranged to slide past the end of the raceway, and between the
bar a' and plate 6, and the casing, and to receive the tack from the raceway and
carry it to a delivering-tube , which begins at one side of the raceway and
terminates at the lower end of the casing. It communicates by a duct e¹ with the
aperture m, so that a tack delivered thereto will be dropped into the centering
device in the throat.
The feed-slide for transferring the tacks one by one from the raceway to the
delivering tube is provided with a recess fl in its face to receive the shank of
the tack from the raceway, and which may be made to register with a recess gl
in the plate b, which recess communicates with the delivering tube.
The feed-slide is likewise provided with two rearwardly projecting cars h¹, which
extend into a transverse groove in the casing, as shown in Figure 1, and which
lie on either side of a cam formed on the driver-bar by cutting away a portion
of the front face thereof (see Figure 4).
The cam is of such a nature and shape that when the driver-bar is depressed,
the slide is moved to have its recess register with the raceway, and when it is
raised, the recess will register with the recess in the plate 6. Thus each time
a tack is driven into the last, a fresh tack is taken from the raceway by the
transferring mechanism, and delivered to the centering device in the throat."
Preferably screws j' are tapped into the ears and hear against the sides of the
cam, so that the slide may be adjusted relatively to the latter.
Referring again to the devices for receiving the tacks and delivering them to
the raceway, it will be observed that the receiver s is provided with an end-wall s¹
converging toward the raceway, as shown in dotted lines in Figure 3, and has
partition walls in parallelism with the end walls and arranged between it
and its front wall. An aperture q' leads from the hopper 7 to the receiver at a
point in front of the partition, so that the tacks are guided by the partition wall
to the raceway, and can travel the distance between the latter and the wall s before
they drop into the overflow, so that they have a chance to fall properly with their
shanks entering down into the raceway. This is of importance in my invention,
as the tacks are guided into the raceway with a very small percentage dropping
into the overflow-box.
The operation of the device is very simple, and needs no explanation additional
to that already given.
A tool formed in accordance with the above description is simple in construction
and highly efficient in operation. It has but few parts, which are not liable to
get out of order, or to be displaced, and which may be manufactured at a minimum
cost.
Having now particularly described and ascertained the nature of my said In-
vention and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:-
1. In a hand tacking-tool, the combination of a casing having intersecting
longitudinal and transverse guide-ways, a raceway leading into the transverse
guide-way, a delivery-tube leading out of the latter at a point laterally removed
from the raceway, a transfer-slide engaging the transverse guide-way and having
a tack-receiving recess for registry with either the raceway or the delivery-tube,
said slide also having a pair of ears or lugs, a spring-sustained driver-bar en-
gaging the longitudinal guide-way and having a cam-strip extending between
the cars on the transfer-slide, a driver carried by said bar, a throat below the
driver and with which the delivery-tube communicates, and a retaining device
in the throat.
2. In a hand tacking-tool, the combination with a receiver for the tacks, con-
sisting of converging bottom walls with a space between them, upright side and
end walls, and a plurality of pairs of converging upright partition walls rising

page_text: from the bottom on either side of the space of a storage-hopper above the
receiver and having an outlet-opening extending over a plurality of compartments
thereof; and a raceway arranged below and registering with the space between the
converging bottom walls of the receiver.
