Improvements in Heel Tacking and Building Machines.
A communication from abroad by FRANK E. SHAW, of 46, Lincoln Street, Boston,
Massachusetts, in the United States of America.
I, THURBUR FRANK RUSSELL, of 25 to 29 Banner Street St. Lukes in the City of
London Managing Director of The Union Leather Co. Limited do hereby declare
the nature of this invention to be as follows:-
This invention relates to certain improvements in what are known as heel tacking
and building machines in which boot and shoe heels are formed by laying a number
of pieces of leather or "cut lifts" in a receptable and tacking or securing them
together the block or heel so produced being subsequently pressed and finished by
other machines.
In one form of machine constructed according to this invention a bed plate is so
pivoted that it may be turned over or reversed. Such plate carries a removeable
receptacle for the "lifts" the bottom of which is interchangeable and is provided
with a number of holes. Pivoted on the bed plate is an arm carrying a closing cover
or lid for the receptacle means being provided for holding said cover tightly down
after the shaped "lifts" have been placed in the receptacle. When this has been
done the bed plate is turned over a tack or nail is dropped into each opening in the
bottom of the receptacle and a block provided with a number of pins is taken in the
hand of the operator the pins are inserted in the holes and by a blow of a mallet on
the block, the pins are caused to drive the nails or tacks into the lifts to hold them
together. The bed plate is then reversed the cover opened and a lever carried by
the bed plate is moved to force a projection through the bottom of the receptacle or
to raise same or in other ways lift the heel slightly so that it may be removed.
Where the machine is to be operated by power the bed plate may be stationary and
the block and pins be carried in guides below the bottom of same a cam carried by
a rotating shaft or a knuckle or other device serving to lift same and drive the pins
up into the lifts, said pins having been previously dropped into the openings in
the bottom of the receptacle before the lifts are put in.
The block and pins may be withdrawn positively or may fall by their own weight
or may be withdrawn by springs.

Improvements in Heel Tacking and Building Machines.
A communication from abroad by FRANK E. SHAW, of 46 Lincoln Street, Boston,
Massachusetts, in the United States of America.
I, THURBUR FRANK RUSSELL, of 25 to 29, Banner Street, St. Lukes, in the City of
London, Managing Director of The Union Leather Co. Limited, 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 relates to certain improvements in what are known as heel tacking
and building machines in which boot and shoe heels are formed by laying a number
of pieces of leather or "cut lifts" in a receptacle and tacking or securing them
together the block or heel so produced being subsequently pressed and finished by
other machines.
In the accompanying drawings are illustrated some forms in which the invention 1
may be carried out.
Fig. 1 is a side sectional elevation, of one form of apparatus.
Fig. 2 is a plan of same.
Fig. 3 is an end view.
Fig. 4 is an elevation of the tack driving implement.
Fig. 5 is a plan of same, and
Fig. 6 is a sectional elevation of a modification of the apparatus.
Referring to Figs. 1 to 3 the apparatus consists of a bed plate a pivotally supported
by journals b in a frame c. To hold the bed plate the frame c has a stop d attached
thereto which engages the back edge of the plate and also a moveable catch e pivotted
to the front of the frame as shown in Figs. 2 and 3 such stop consisting of a toothed
pawl suitably weighted so that it will swing back into the position where it engages
with the front of the plate after it has been moved aside. The stop d is formed in
one with a plate d¹ held to the frame by slots through which pass bolts so that the stop
may drop the length of the slots.
On the plate is a receptacle f the interior of which is shaped to the size and
approximate form of the heel to be built. This receptacle is bolted or otherwise secured
to the plate so that different sizes and forms may be substituted therefor. Beneath.
the receptacle the bed plate has a removeable piece y forming a bottom for the
receptacle a set screw g₁ serving to hold it in place so that by removing the screw
another may be substituted. This plate g is pierced with holes g2 and with a further
hole in which is carried a plug g³ supported on the end of a lever h pivoted at h¹ and
regulated by a stop h².
The receptacle f has a cover i suitably shaped to conformn thereto such cover, being
carried by a lever j pivoted at . To this lever is pivotally hung a cranked and forked
lever the end of which carries a roller l' and is adapted to embrace a horn a¹ forming
part of the bed plate so that the lever j may be drawn down to the horn by the
lever l.
m Fig. 4 is a block having a suitable handle and pins m¹ which correspond with the
holes g2 on the plate g.
The operation of the device is as follows. The receptacle f being filled with
the cut pieces of leather or "lifts" of different sizes to conform to the shape of the
receptacle, the lever j is brought down so that the cover holds the pieces in place, the
lever is then brought into engagement with the horn a¹ so that the pieces are
compressed and held in that condition. The bed plate is then turned over, the stop d
dropping as described so that the plate when resting on the top of same is level with
1

page_text: the frame, the frame remaining in this position by reason of the weight of the
levers j l.
The operator then drops a tack or headless nail into each of the holes g² and taking
the block m inserts the pins m¹ into the holes above the tacks and with the blow of
a mallet drives the tacks into the heel. The bed plate is then reversed the
receptacle opened and by means of the lever h the plug g³ is forced up so as to
knock the heel out or raise it sufficiently to enable it to be removed.
In Fig. 6 is shown a modification where the machine is partly operated by power
the parts being the same as previously described except that the block is held in a
guide box m² and is connected by toggles n n' with a cam o on a driving shaft p the
toggle n¹ forming also the strap of the eccentric. To the toggle n is attached a
handle q by which the toggles may be straightened or bent. In this case the operator
drops the tacks into the holes g² from the inside of the receptacle before the lifts are
placed therein.
In
The shaft p is constantly running but without operating the block m so long as
the toggles are bent but when the toggles are straightened by means of the handle q
the block will be forced up by the eccentric and the tacks driven into the heel.
this case the plate is not reversed as will be understood and therefore is not provided
with the catch and stop.
Having now particularly described and ascertained the nature of my said invention
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 heel tacking and building machine, a pivoted bed plate, a receptacle for
the "lifts" attached thereto, means for closing the receptacle and compressing said
"lifts," holes in the bottom of the receptacle through which tacks may be dropped
when the plate is reversed and means for driving the tacks and discharging the built
heel substantially as described.
2. In a heel tacking and building machine, a pivoted bed plate, a receptacle
attached thereto, a pivoted lever carrying a cover for the receptacle, a removeable
bottoin plate for the receptacle containing holes for the tacks and a plug and means
for raising the plug substantially as described.
3. In a heel tacking and building machine a receptacle for the "lifts" carried by
a bed plate, a removeable perforated bottom for said receptacle and a block having
pins adapted to force the tacks or the like through the holes in the bottom of the
receptacle into the heel substantially as described.
4. In a heel tacking and building machine, the combination with a bed plate, a
receptacle attached thereto, a perforated bottom to same, means for closing the
receptacle and compressing the lifts and means for discharging the formed heel, of a
block having pins adapted to be forced through the holes of the bottom, toggles
attached to the block and means for straightening and driving the toggles
substantially as described.
5. The arrangements and combinations of parts forming the improvements in heel
tacking and building machines substantially as described and illustrated.
