6 Claims. (C1. 12-125)
This invention relates to a device for holding
the heel and the heel end of a shoe in proper rela
tive positions while the shoe and the heel are be
ing nailed on or otherwise secured together.
The device is particularly adapted for attach
ing wooden heels to women’s shoes and is con
structed and designed for use in shoe repair shops.
To this end, the invention embodies certain novel
features of construction whereby it is especially
10 adapted for ready attachment to or removal from
a work bench or a counter.
In addition, the
invention contemplates and provides novel means
for clamping the heel and shoe in proper relative
position without injuring or marring the heel or
15 shoe.
Additional objects of the invention are to- pro
Vide a shoe clamp which is manually operated,
simple and inexpensive in construction, and
which is composed of few parts separably united
20 and compactly arranged.
With the foregoing objects in view, the inven
tion consists in the novel construction and arrangement of parts hereinafter more fully de
scribed and pointed out with reference to the
25 accompanying drawings, wherein:
Figure 1 is a side view of the shoe clamping
device in operative condition, the heel end of a
shoe and the shop counter being indicated in
dotted lines.
Fig. 2 is a top plan view of the device.
Fig. 3 is a front end View thereof.
Fig. 4 is a fragmentary side view partly sec
tioned to disclose the heel clamping members.
Fig. 5 is a horizontal section on line 5-5 of
Fig. l.
Fig. 6 is a fragmentary detail View of the front
heel clamping member, partly in section.
In order that the device may be conveniently
attached to and supported on the corner of a
40 bench or counter, such as indicated in dotted
lines at 1, in Fig. 1, the various units are mounted
on or made integral with a base plate 9 having
laterally spaced lugs Ill and I9’ depending from
the under side thereof adjacent one end of the
plate in overhanging abutting relation with one
edge of the counter or other support; the plate
being fastened to the support by screws, bolts
or other fasteners, inserted through the holes I I
in the plate. Integral with the plate and eX
tending vertically of the upper side thereof is a
post having a T-shaped body portion I3 sur
mounted by a head I5 which is substantially
square in cross section.
The head l5 is grooved
or recessed in its top side to provide spaced bear~
55 ing lugs I1 and I1' which are apertured to receive
the ends of the fulcrum or pivot bolt I9 at one
end of an arm 2l, which is provided at its oppo
site or free end with a vertically disposed screw
threaded bore in which is screwed a long clamp
ing screw 23. The screw 23 is provided at its Ci
upper end with a handle 25 and at its lower end
with a swivelled work-engaging member 21. _Arm
2I extends forwardly of the broad face or head of
post I3 with its free or screw bearing end over
hanging the end of the base plate having the
depending lugs I9 and I9'. By reason of its
pivotal connection with post I5, the arm 2l is
movable from a horizontal to a vertical position
for substantially an arc of 90°, and at its pivoted
end is provided with a stop lug 29 adapted to abut
the rear edge 3l of the post head I5 when the
said arm is vertically disposed. Suitable means
are provided for locking the arm 2l and clamp
ing screw 23 in clamping position. The particu
lar locking means illustrated comprises a plate
33 flexibly connected to the post by a string 35
and carrying a locking pin 36 insertable through
aligned openings in the post bearing lugs I1 and
I1’; the arm 2l having an aperture adapted to
register with the pin receiving openings in the
post bearing lugs when the arm ZI is horizontally
positioned as illustrated in Fig. 1. The T-shaped
portion of the post serves as a vertical guide for
the carrier 31 of the heel back clamping member
39. Carrier 31 comprises a tubular block having 30
its rear end cut out, as at 4 l, to receive the broad
head of the T-shaped post I3. A pair of angle
straps 43 and 43', preferably of spring metal,
are attached by screws 45 to the rear end of car
rier 39 so as to engage rearwardly of the head
of the post I3 and transversely of the rear flange
thereof, as shown in Fig. 5; the said straps being
secured at their outer ends by a ring bolt and
nut assembly 41 whereby they may be clamped
against the post I3 to hold the carrier 31 sta 40
tionary on the post. The clamping member 39
carried bythe member 31 is preferably a wooden
plug having its outer end concaved and arcuate
to ñt snugly against and around the back por
tion o-f a shoe heel 49.
Several different types 45
of plugs 39 will be used separately’with carrier
31 to accommodate different types of shoe heels,
and the carrier is adjustable vertically of post
I3 to enable the operator to set the plug or clamp
31 in exactly the right position against the back 50
of the shoe heel as the particular design and
shape of the heel may require.
In advance of the back clamping member 39
and cooperably positioned relative thereto is a
front clamping assembly comprising a shaft 5I
journaled for rotation in lugs I9 and |0’ of the
ings extending transversely therethrough and lat
post, a heel front clamping member on said plate
and movable to and from proximity with the
bask heel clamping member, and a shoe clamping
member mounted on said post and adjustable to
erally spaced apart to be on the outsides of lugs
I0 and l0', these openings being adapted to re
a position for clamping the heel end of a shoe 5
against a heel clamped between the said front and
ceive the legs of a U-shaped member or yoke 55

bearing against one leg of the yoke, as shown in of a shoe heel, a member pivotally mounted on
Fig. 6. The means for rotating shaft 5| to .place said plate for engaging the front portion of a
yoke 55 into and out of heel clamping position, shoe heel to clamp the latter against the member
consists of a hand lever 59 pivoted at 6| to a lat
supporting the back of the heel, and an arm
eral extension 63 of the base plate and having its
pivotally mounted in said post for adjustment to
ward and away from the heel clamping members,
lower end pivotally connected at 65 to one end
of a link 61 which has its opposite end pivotally
connected at ‘69 to the crankr53 of the shaft.
Movement of the handle end of lever 59 to the left
of Fig. l causes the clamping yoke 55 to be swung
away from the back clamping member 39 or into
heel releasing position. Reverse movement of the
lever causes clamp yoke 55 to press the Vheel ñrm
ly against the back clamping member »39, the op
posite end of which is in abutment with the broad
face of the T-shaped post |3. Fastened to the
base plate 9 by bottom lug '|| and disposed con
centrically with the axis of the lever 59, is a lever
quadrant '|3 having an arcuate slot 'l5 through
which extends the shank of a headed lbolt 'l1 car
ried by the lever 59 and having a wing nut 19
screwed on its inner end. When the wing nut is
screwed up tight, the lever is clamped to the
and a clamping screw at the free end of said arm 20
for clamping the heel end of a shoe upon the shoe
3. A shoe heel clamping device comprising a
base plate, a pair of heel clamping members mounted on said plate, one of said clamping
members being mounted to turn about a ñxed
axis and the other member being mounted for
adjustment vertically of the plate to accommodate
heels of varying heighths, 'a clamping screw
adapted for insertion in the heel end of a shoe
for clamping same against the top portion of a
shoe heel, clamped between the heel clamping
members, means carrying said clamping screw
and adjustably connected with said plate for
moving said clamping screw into and out of shoe
clamping position, and individual means asso

In using the device, the wooden heel' 49 is
placed on base plate 9 and clamped between
clamping members 55 and 39 by proper manipula
tion of lever 59. The shoe Yto which the wooden
heel is to be attached is then positioned with‘the
heel end of the shoe resting upon the top of the
wooden heel 49 as indicated in dotted lines in
Fig. 1 and the arm 2| is then swung into position
so that the clamping screw 23 depends inwardly
of the shoe with the bearing plate 2‘! pressing the
heel end of the latter against the heel. The screw
23 is then rotated by the handle 25 to clamp the
heel end of the shoe and the wooden heel in pro
per relative position. In this conditionofjthe
clamp, the first two nails are driven through. the
>bottom of the shoe and into the heel in front of
the bearing end 21 of the clamping kscrew 23.
The latter is then turned and the looking pin 36
pulled out to release the arm 27| which may be
then swung upwardly and out of the ïway. ’ The
process `of attaching the heel and shoe is then
ñnished by driving in the next three nails, there
generally being ñve nails in all in the heel of va
»woman’s shoe.
From the foregoing, it is Vthought that the op
eration and 'construction of the device will be
readily understood.
