page_text: heel is to be pressed. This plate c is attached, to the shaft C by means of a set
screw and may be removed and another plate of different shape be substituted if
desired. Upon a pair of ears D on the plate C is mounted the lever D¹. d is a
connecting rod, one end of which is pivoted to one end of the lever D', the other
end lying against a cam d² on a shaft carrying a hand wheel d³, being held in
place by a slotted link d' attached to the part C', and pin d, which lies also in a
slot in the post. See Figs. 7 and 8. Upon the other end of the lever D' is pivotally
mounted a spindle D' carrying a jack D³, the upper end of which furnishes a
support for the last of the shoe to be burnished.
The spindle and jack are adjustable in length so that the machine may be used
to burnish heels of different heights.
The spindle and jack being swung forward through an arc of thirty degrees to
receive the shoe, are then swung back into position shown in Figure 1. The hand
wheel is then turned to so operate the can d² as to depress the end of the
lever D' to which the connecting rod d is attached, thus elevating the spindle and
jack D, D³ and binding the heel against the plate c and holding it fast, the reverse
motion of these parts allowing the shoe to be removed.
The mechanism for giving the shoe a rotary motion is as follows-The shaft E
on which the plate C is mounted, passes through a sleeve F to which it is splined
at so as to rotate with the sleeve but move vertically in it, and it sets upon a
stud N so that the sleeve and shaft will oscillate together thereon, (see Fig. 3).
The stud N is mounted upon the cam G by means of which it and the jack and its
supporting mechanism is raised and allowed to fall in order to present the entire
height of the heel to the burnishing tool. The. sleeve F lies within a bearing F2
which is hung in a yoke F³, so that the jack may swing out from the tool as the
diameter of the heel increases. This yoke is adjustably attached to the post A. so
that the position of the jack with reference to the tool may be adjusted according
to the sized heel to be burnished.
To the sleeve F is fastened a gear E into which meshes a segment gear E
which turns on a stud E³ mounted on the lever M in a way to be described. This
stud passes up and screws into the arm F which is cast on to the bearing F²
(see Fig. 3). The segment gear is oscillated by means of a connecting rod E
which connects it with a crank pin E mounted on a disk E', this disk being on the
end of a shaft E8 which also carries at its farther end, a gear E meshing into a
worm E on the main shaft B. This shaft E is mounted in a swinging bearing e
at the end nearest the disk E, and at its other end is mounted in a swinging
bearing e. The bearing e is pivoted in a yoke mounted in an eye projecting
from a post A. The bearing e is pivoted in a yoke mounted on the rode which
passes through two guides e and is mounted on the end of a lever et hung from the
end of the hanger ee is a spring which is so located as to keep the gears E, E
in mesh. This levere is operated by means of a treadle 8 fulcrumed on the
hanger e as shown, this treadle being held by means of the spring e".
This treadle is locked down, on being depressed, by means of the lever H
fulcrumed at h, which is so mounted so it may stand upon the projection HI' on the
treadle e as shown in Figure 3. his a spring which tends to draw this lever into
position on top of projection H¹.
The cam G which is operated and is for the purpose to be described, carries a
pin which, as the can rotates, trips this lever H so as to throw it off from the
projection Hand consequently allow the spring to act and separate the
and E, thus stopping the action of the parts which derive their motion from the
shaft E
gears E'
The cam G is operated by means of a gear and worm G1, G2, the worm being
mounted on the end of a shaft G³ carrying a pulley G belted to the pulley E, so
that when the shaft E which carries the pulley E, is operated, the cam G will be
rotated, this rotation lifting stud N carrying the jack D³, so as to present the entire
vertical surface of the heel to the burnisher in succession, while the segment E2 is
operating to oscillate the heel. When this cam G has rotated from the position shown

page_text: in Figure 3 to such a position that the stud N is mounted upon its outer surface near
its greatest radius, it will be seen that the pin will have passed around from the
position shown in Figure 3 to a position where it will strike the outer side of the
upper end of the lever H. The farther motion of the cam G in the same direction
will cause the pin to trip the lever II, thereby releasing the treadle in the
manner referred to above, and throwing the entire rotating and lifting mechanism
out of operation at the instant when the stud E drops from the highest part of the
cam to the lowest, (see Fig. 9).
A second treadle J mounted on the shaft is provided in order to feed a particular
part of the heel to the burnisher tool so as to touch it up in case it needs going
over the second time. When such operation is to be accomplished, the treadle
has been released as above described and has been acted upon by the spring e so
that these parts will be in the position shown in Figure 9. Depressing the treadle J
will bring the cam piece j mounted on a collar attached thereto, in contact with the
treadle so as to depress it and consequently bring the gears E, E in gear and
so operate the segment gear E2. At the same time however, it is necessary to raise
the jack and consequently the heel, to the proper height and hold it there and also
disengage the automatic jack raising mechanism, riz.-the cam from its operating
mechanism. To raise the jack, the inner end of the treadle J strikes the end of the
lever Jon which is mounted the hanger J2 which straddles the stud N and is
pinned to it, so that by lifting the lever J', the jack is lifted. By this means, the
heel may be raised to any desired height and so brought to the burnishing tool.
In order however, to disengage the cam mechanism so that under these circum-
stances, the cam G will not operate the heel, there is provided on the shaft
a.cam K which, when the shaft is rotated by the depressing of the treadle J,
depresses an arm & attached to a stud 4, provided at its upper end with a yoke
carrying a bearing in which the shaft is journalled. Depressing the treadle-J
therefore, depresses also the worm G2, so that it is no longer in gear with gear G
By this means, the automatic rotary motion of the jack is not prevented but its
vertical motion is made to depend upon the will of the operator and is not
automatic.
There is also provided means for adjusting the pressure on the various parts of
the heel so that the pressure on the heel seat will be less than the pressure at the
top lift. This is accomplished by mounting a lever L loosely on the shaft and
connecting the end of this lever I by means of connecting rod L¹ with a second
lever M. suitably connected to the lower end of the jack support. It is better to
make use of a portion of the hanger J as a link to connect this lever M with the
jack support, but the parts may be connected in any other suitable manner pro-
vided they are enabled to move pivotally with respect to each other. It is better
to provide the upper end of the connecting rod L with a collar m² which is moved
on a screw m carrying the hand wheel m, so that its position under the lever M
may be adjusted. This lever M is pinned to the bottom of the pièce carrying
the stud E3 which is screwed into the arm This arm therefore supports not
only the segment but the entire system of levers below it. L' is a spring lying
between a nut and the under side of base plate A', so that by turning the nut
the pressure of this spring may be adjusted. The purpose of this spring L² is to
press the heel against the burnishing tool and by adjusting its strength, that pressure
may be adjusted. A further adjustment may be had by altering the position of the
collar m² under the lever M. It is observed that by changing the shape of the
cam G, the length of time during which the tool will dwell on any portion of
the heel will be changed.
In Figures 10 and 11 there is shown a modification of the burnishing mechanism.
In this case the arm or lever is a double bell crank fulcrumed on the stud 61,
what may be called the cross arm, namely:-the arm at right angles with the arm
carrying the burnisher, being lettered b At each end of the shaft as shown in'
these figures, is a crank pin 61, which is connected with the corresponding end of
the cross arm by means of a connecting rod 616, these crank pins being set on

page_text: opposite sides of the axis of the shaft. Each connecting rod 10 is provided at each
end with a yoke by means of which it is connected with a journal box. In one
journal box is journalled the crank pin 41, the other journal box holding a stud in
the end of arın 6 so that with each oscillation of the burnisher, the angle of the
connecting rods with the shaft and cross arm may be changed as circumstances
require.
The operation of this mechanism will be easily understood. By means of the
crank pins an oscillating movement is given to the cross arm, arm and
burnisher. The parts. being balanced, the burnisher may be run at a very high
rate of speed with comparatively little noise and jar. The universal joints are
necessary as shown, because the angle between the connecting rods and shaft and
cross arm are continually changing. It is obvious that instead of the arm 69 and
cross arm, a single bell crank could be used, but the form above described is
much more effective, being well balanced and easily operated.
