9 Claims. (Cl. 12-‘-i)
This invention relates to ?nishing machines a rotating tool it) which applies a ?nishing
and is illustrated herein as embodied in a ‘machine
adapted for ?nishing the heels of shoes.
The ?nishing of shoe heels by the use of the
5 usual type of ?nishing machine requires an oper
ator to present the work successively to a number
of different ?nishing tools arranged at spaced
points along a ‘rotating shaft. The losses of time
and energy of the operator occasioned by thus
10 moving the work from place to place are ma~~
terial and ‘are factors which it is an object of the
present invention to avoid.
I
To this end, the presentation of the work to
the" ?nishing tools of the ‘illustrated machine is
15 effected at one operating point past which the
tools are moved in succession as a result of being
mounted, in accordance with ‘an important fea
ture of the invention, on a constantly moving
carrier or turret, the spacing of the tools on the
20 turret being determined with reference to the dif
ferent amounts of time required to carry out the
granted December 20, i898, upon the application 5
of Z. Beaudry, and is ?'Xed on the left-hand end
of the shaft i2 (Fig. 1) which is supported ad
jacent to the tool by an arm M, the latter being
fixed to a bracket l6 which is fastened to the
machine column iii. The shaft I2 is also ro- 10
tatably mounted at its right~hand end in a hear
ing member 2E1 ?xed to the top of the column It.
The shaft 12 is driven by a belt 22 which runs
over a pulley 24 ?xed to the shaft l2, the belt
being driven from any suitable source of power, v15
as an electric motor 26.
The ?nishing medium is supplied to the tool it
by a disk 28 rotatably mounted in a medium
holder 30, the construction and mounting of
which is the same as that of the machine illus~ >20
trated in Letters Patent of the United States No.
various operations so that there is substantially no

lost time between the completion of one opera?
tion and the arrival at the operating point of the
tion of J. F. Standish. As will be fully understood
from the above-mentioned Standish patent, ad,
justment of the disk 28 transversely of the axis 25
of the tool It is effected by turning a crank 32
25 succeeding ?nishing tool.
>
As herein illustrated, the ?nishing tools have a
uniform orbital movement with respect to a tool
for applying ?nishing medium to the work, the
applying tool being located conveniently with re—
30 spect to the operating point of the ?nishing tools
whereby a minimum of movement of the operator
is required in presenting work to the ?nishing tools
after the work has received an application of
?nishing mediumv

Fig. 2 is a side elevation illustrating the ?nish
ing tools and the turret upon which they are
mounted as viewed from the left-hand side of the
45 machine shown in Fig. 1; and
~
which operates a slide 34 on which the holder 39
is mounted. The slide 34 is mounted in a dove
tail slideway formed in a block 35 which may be
clamped to the upper end of the bracket iii in 30
any desired position of adjustment axially of the
shaft 52 by means of bolts 33 which pass through
elongated slots E6 in the bracket 55. The disk
28 may be driven from the shaft M by any suit
able means, such as beveled gear connections, as 35
illustrated in the Standish patent, or by means of
a belt 42,'as in the present machine, which runs
over a‘ pulley "i4 ?xed to the shaft l2 and a pulley
58 associated with the disk 28.
The shoe heel, having had wax applied thereto 40
by the tool it, is next moved to an operating point
in front of the machine to which ?nishing tools
comprising a padding wheel (38, a rand burnishing
and beading wheel 50 and two rotary brushes 52,

being bodily rotated, as will be described later,

heads 56. Alined radially with respect to the
slots 54 are other slots 68 formed in the disk 58
and adapted to receive clamp bolts 10 for secur
ing the heads 55 to the disk 58. The disk 58 is
rotated at a relatively slow uniform velocity, so
that the operator has enough time to present the
work to the tools, by a gear train comprising a
worm gear 12 ?xed to the hub 65, the gear being
driven by a worm 74 carried by a shaft 15 jour
10 naled in an extension of the bearing member 28
and having mounted on its end remote from the
worm 74 a worm gear 18. The gear "I8 is driven
by another worm 86 mounted on a shaft 82 jour
naled in the bearing member 20 and carrying a
15 pulley 84 at its outermost end in the plane of the ~
pulley 24 to facilitate its being driven by the belt
22. Thus, when the motor 26 is operated, the
wax-applying tool shaft l2 will be rotated and the
?nishing tools 48, 55, 52, and 54 will be bodily ro
tated with respect to the tool iii at such a speed
that each tool will remain in the vicinity of the
operating point above referred to long enough to
enable an operator to ?nish that operation for
which each operating tool is intended to be used.
25
The angular spacing between the ?nishing tool
heads 55, as illustrated herein, is irregular and
is to be determined with reference to the differ
ent amounts of time required for each ?nishing
operation, this angular adjustment of the ?nish
30 ing tools with respect to each other being per
mitted by the slots 64 and 68 which allow the
heads 55 to be adjustably clamped in the turret
in any desired relation to each other.
t will
be noted with reference to Fig. 2 that the greatest
35 spacing between the tool heads 56 exists between
that carrying the brush 54, which is the last ?n
ishing tool to be brought to the operating point
during one cycle of the operation of the machine,
and the padding tool 48 which is the ?rst tool
to which work is presented after it has received
an application of wax from the applying tool Hi.
This wide spacing of the padding wheel 48 and
the brush 54 gives time for the operator not only
applied thereto, the shoe heel will be ?nished by
being operated upon successively by the padding
wheel 48, the rand burnishing and beading tool
55 and the brushes 52 and 54. Owing to the
above-described slot arrangement by "which the
heads 56 may be angularly adjusted relatively
to each other in the turret, the spacing between
the ?nishing tools may be readily controlled with
reference to the time required for each particu
lar ?nishing operation so that there will be sub
stantially no lost time between successive finish
ing operations as explained above. It will thus
be apparent that a minimum of effort is required
of the operator in presenting the work to the
applying and ?nishing tools and that by prop
erly relating the speed of rotation of the turret
and the spacing of the ?nishing tools an eilicient
speed in carrying out the various ?nishing op
erations is encouraged.
Having described my invention, what I claim as
‘new and desire to secure by Letters Patent of the
United States is:
1. In a shoe ?nishing machine, a rotating
?nishing medium applying tool, and a plurality of
finishing tools mounted for movement bodily in -
a path surrounding the axis of said applying tool
at a constant velocity’ past an operating point at
which a shoe is presented to said tools in succes
sion, said ?nishing tools being irregularly spaced
so as to permit the operator to interchange a l
?nished shoe for one to be operated upon and
apply medium thereto during the period when
the last ?nishing tool leaves and the ?rst tool
reaches the said operating point.
2. In a shoe ?nishing machine, a plurality of
?nishing heads each comprising a tool, a carrier
for said heads, means for moving said carrier con
tinuously whereby said tools are successively
moved through an operating position at which a
shoe is presented to said tools, said heads being 40
mounted for adjustment on said carrier in the
direction of itsmovement thereby to permit spac
ing said heads relatively to each other in accord
ance with the time required for each ?nishing
to place a ?nished shoe aside but also to pick
up one to be operated upon and to apply wax to operation.
3. In a shoe ?nishing machine, a plurality of
the latter as the padding tool 48, owing to the
movement of the turret, is moved to the oper . ?nishing heads comprising tools adapted to be

iii to the operating point at which the work is
presented to the ?nishing tools 48, 55, 52, and
54, the operator is able merely by swinging his
body and without moving his feet to move the
shoe from the applying tool id to the ?nishing
tools. After having had ?nishing medium or wax

at a greater distance than that between other
successive tools thereby to permit the inter
