I, ALFRED BURKE FOWLER, of Exeter in the County of Rockingham and State of
New Hampshire, United States of America, Engineer, do hereby declare the nature of
my 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 improvements in heel burnishing machines, and it is
carried out as follows, reference being had to the accompanying drawings, where, Fig.
represents a plan view of the machine; Fig. 2 represents a vertical longitudinal
section; Fig. 3 represents a cross section on the line A B shown in Fig. 2; Fig. 4
represents an enlarged cross section on the line CD shown in Fig. 3; Fig. 5 repre-
sents a cross section on the line E F in Fig. 2 showing the jack, its bracket and
locking device; Fig. 6 represents a plan view of the outer end of the jack supporting
bracket; Fig. 7 represents a vertical section of the waxing device for applying wax to
the rotary burnishing tool; Fig. 8 represents a cross section on the line G H shown
in Fig. 7; and Fig. 9 represents a vertical section on the line I-K also shown in
Fig. 7. Fig. 10 represents an enlarged end view of the heel shaped cam for raising
the burnishing tool out of contact with the heel after the latter is burnished.
a is the main frame or standard to the base of which is secured the upright rear
post bas shown in Fig. 2. c is the driving shaft located in bearings in frame a and
post and provided with fast and loose pulleys c¹ c" as is common in machines of
this kind. a is a bearing secured to top of frame a in which is located the rock
shaft d, its rear end being supported in a bearing in the upper end of post bas
shown in Fig. 2. To shaft d are secured the upwardly projecting arms or levers d'
and d" in which is journalled the projecting ends of the small pulley e, the latter
having a square hole through its centre in which is loosely fitting the square shaft f.
Between the arms d' and d¹¹ is loosely journalled on the rock shaft d the pulley d³ to
which a rotary motion is imparted by means of belt leading from pulley e³ on
driving shaft C
and by means of belt el a rotary motion is imparted from pulley d³
to pulley e and its longitudinally movable shaft f
On the rock shaft d is splined the hub of the armi or lever g in the upper end of which
is journalled the cylindrical end f¹, of the square shaft f, having collar f" secured to

page_text: it at the rear of the upper end of lever 7 and universally jointed at f³ to the rotary
burnisher shaft, which latter is journalled in the yielding bearings i and land has
secured to its forward end the burnishing tool h¹. A longitudinal reciprocating
motion is imparted to the burnishing shaft by means of the rock lever the upper
end of which is pivoted to the ring g' located in an annular groove on the hub of
lever said lever being adjustably pivoted to the stationary bracket m by means of
fulcrum block n that is adjustable in slots l', m³ in lever and bracket m respectively
and by which means the amount of reciprocation of the burnisher tool in the direction
of its shaft can be regulated according to the height of the heel that is to be
burnished.
The lever is reciprocated by means of the eccentric block L secured to driving
Shaft c, which block is surrounded with the ring L'as is common in making eccen-
tries to ring L' is secured the rod L the upper end of which is pivoted to the bar
or block I, the latter being vertically guided in the bearing piece I secured to
post as shown in Fig. 2. A rod or link L' connects the upper end of block L³ to
the lower end of the bent lever and it will thus be seen that a quick reciprocating
motion is imparted to the burnisher shaft from the rotary driving shaft and the
intermediate connecting mechanism as described.
b
To the forward end of the rock shaft d is secured the lobed gear shown in
Figs. 2 and 3 the teeth of which intermesh in the teeth of the segmental lobed gear o
that is pivoted on the bolt or stud o¹ secured to frame a as shown in Figs. 2 and 3.
This lobed gear o is rocked on its fulcrum by intermediate connecting mechanism
from the driving shaft cas will hereinafter be described. The object of the lobed
gears do is to impart to the burnisher tool such an oscillating motion as to cause it
to follow the curvature of the heel with a uniform velocity from the front of the heel
to its rear and to the front opposite and back again to the starting point and thus
cause each portion of the heel surface to be equally acted on by the burnisher.
To the upper end of the lobed gear are secured the guide rods d d which are
secured together in their upper ends by means of yoke and set screws d d or
equivalent devices. " is the adjustable bearing for the burnisher shaft and it is
pivoted loosely to the cars ³ ³ located on the guide rods as shown in Figs. 3
and 4, such ears being free to move up and down on the said guide rods de de, and
the bearing free to rock on the pivots of said ears as the burnisher is raised or
lowered. The upper ends of the rods are screw threaded and provided with
thumb nuts DD as shown in Figs. 2 and 3. On the guide rods de do between the
upper side of bearing and underside of thumb nuts D¹ I are located the
springs DD which serve to automatically hold the burnisher tool against the heel
that is being burnished as shown in Fig. 2. By adjusting the thumb nuts D¹ D' on
the rods any desired pressure of the burnisher against the heel may be
obtained.
The lobed gear o is automatically rocked on its fulcrum o¹ by suitable intermediate
connecting mechanism from driving shaft c as follows: to the inner end of said shaft e
is secured the pulley & shown in Figs. 2 and 3; by means of the belt leading from
said pulley to the pulley p the latter is set in a continuous rotary motion; the
pulley p is loose on spindle p¹ which latter is journalled in bearing p" and has secured
to its inner end the bevel gear shown in Fig. 2. On spindle p¹ is splined the
friction clutch which is operated to and from the loose pulley p by means of the
shipper rod p located in bearings in frame a and having secured to its rear end
the small arm p the inner end of which fits in a groove in the hub of friction clutch p⋆
as is common in devices of this kind; the rod is connected to a treadle mechanism
by which it is operated in one direction to disconnect the friction clutch p from
pulley p and to a spring by which the friction clutch is connected to said pulley p as
will hereinafter be more fully described.
The bevel gear p³ meshes in the teeth of the bevel gear 9 secured to the worm
shaft provided with the worm q shown in Figs. 2 and 3. Worm-shaft q' is
located in bearings ³ ³ secured in a suitable manner to the interior of the hollow
standard a preferably to a plate q* that is secured to standard a. The worm q¹!

page_text: meshes in the teeth of the worm-wheel 75 the shaft or central spindle of which is
suitably journalled in a bearing secured to plate 7 as shown in Fig. 2. To the face
of the worm-wheel q is secured the crank pin y having pivoted to it the lower end of
the link or rod q' the upper end of which is pivoted to an arm or extension o" on
the segmental lobed gear o, as shown in Fig. 3.
Thus it will be seen that an oscillating motion is imparted to the burnisher shaft
from the rotary driving shaft c, as long as the friction clutch p is held in contact
with the loose pulley p, and such oscillation of the burnisher shaft is stopped when
the clutch p is withdrawn by the treadle mechanism from the loose pulley p.
The bearing for the burnisher shaft is guided up and down in a forked arm i
secured to the rock shaft d.
Ris the jack supporting bracket secured in a suitable manner to the standand a
and having its outer end preferably supported from the floor by means of an adjustable
metal rod or pipe R' as shown in Fig. 2.
Upon the bracket is supported my improved rotary duplex jack for holding
the shoes the heels of which are to be burnished and said jack is constructed as
follows:
It consists of the jack post S of which s is the base plate that is adapted to slide in
guides on top of bracket R as shown in Figs. 5 and 6; such sliding motion of the
jack being limited by means of the slot R in top of bracket R and the pin or screws
passing through such slot and secured to base plates as shown in said Figs. 5 and 6.
The guides extend only a portion of the length of the top of bracket R as shown in
Figs. 2 and 6 so that when the base plates of the jack is drawn backward to the
limit of its stroke, it is disengaged from said guides and the post S can then be turned
half a revolution around its axis and pushed forward so that its bases will enter thie
guides and thus guide the shoe properly to the burnisher tool, and when in such
position it is automatically locked by means of the spring pressed pin 1 located in
bearings in the bracket R and actuated by means of the spring for forcing the
upper end of said pin into a perforation in the bases of the jack post as shown in
Figs. 2, 5 and 6. Said spring-pressed pin is unlocked from the jack plate by means
of a foot treadle and connecting mechanism as will be hereinafter more fully shown
and described.
At a proper distance apart are made in one piece with the upper end of the jack-
post S the horizontal tubular bearings S S in which are located respectively the
sleeves SS each of which is splined or otherwise guided in its bearing $1 to
prevent its rotation therein; the interior of each sleeve S₁ is screw threaded and into
it is screwed the screw-threaded spindle S3 which is held from longitudinal motion in
said bearing S¹ by means of the nut St screwed into one end of the bearing S¹ and a
collar on spindle S³ and a crank or band wheel S³ in its outer end as shown in Fig. 2,
similar to the manner in which tool stocks are arranged and operated in metal turning
laths and similar tools. In its outer end the sleeve Shias attached to it a disk or
plate S adapted to rest against the insole of the boot or shoe while being held on the
jack. To the jack post S are secured the brackets or bent arms $7 $7 the upper ends of
which terminate opposite to the sleeves $"S" and are there provided with detachable
top lift rests S S shown in Figs. 1 and 2.
.
The shoe to be burnished is clamped in position (as shown in dotted lines in Fig. 2).
between the top lift rest S8 and the plate S on the end of sleeve S" and secured firmly
in place by means of hand wheel S and screw spindle S³. While one boot or shoe is
being burnished, another one is secured to the opposite jack portion between the
parts S and Ss and as soon as one shoe is finished, the locking pin is withdrawn
from the jack by means of a foot treadle, the jack is drawn towards the operator,
turned half a revolution around its axis, pressed forward and locked in position by the
pin and held there while another boot heel is being acted on, during which opera-
tion the first boot or shoe is removed from the jack and another one secured to it and
so on.
•
T is the foot treadle pivoted at t to a bracket or other stationary part of the
machine, as shown in Fig. 2; to the inner end of the treadle T is pivoted the link

page_text: or rod T¹ the upper end of which is connected to the bar or plunger T" the latter
being guided in the bearing a secured to the standard a as shown in Fig. 2; to
the upper end of the bar T is secured the tool lifter T3 shown in Figs. 1 and 2 and
enlarged in Fig. 10 which piece is made in the form of an enlarged heel and when
pushed upwards by means of treadle T it comes in contact with a projection /*
on the bearing shown in Figs. 2, 3, 4 and 7, causing the burnisher shaft to be
raised against the influence of its springs D" D1 and causing the tool to be raised
or forced outwards sufficiently to be disengaged from the heel of the boot or shoe,
by which means the burnisher tool can be instantly withdrawn from the heel as
soon as the latter is finished and thus allow for the manipulation of the duplex jack.
To the rod T is suitably connected the lever U that is pivoted at u to the bracket R
and is provided with an extension U₁ adapted to rest against a collar or projection ³
on the lock spindle as shown in Figs. 2 and 5, and by this means the lock-spindle >
is depressed against the influence of its spring and disengaged from the jack plate s
when the treadle T is depressed. The treadle T tool lifter T³ and lever U are
automatically returned to their normal positions shown in Fig. 2, when the pressure
on treadlo T is relieved by the influence of the spring U the upper end of which is
connected to the lever U, or its connections, and the lower end of said spring secured
to the standard a as shown in Fig. 2.
For the purpose of actuating the shipper bar 2 from the treadle T I make on the
link or rod T a pair of projections or teeth t¹ ti which as the treadle is raised and
lowered come in contact with a projection t¹¹ on the bell crank lever t³ pivoted to the
frame a or other stationary part of the machine, and having one of its ends pivoted
or otherwise connected in a suitable manner to shipper rod as shown in Fig. 2, and
by this means the friction clutch is withdrawn from the loose pulley p when the
treadle T is depressed thus stopping the oscillating motion of the burnisher and its
shaft at the same time as the tool lifter raises the burnisher tool away from the heel
of the boot or shoe and simultaneously with the withdrawal of the jack locking pin ₁₁
as heretobefore described. The action of the spring U" on lever U and link T causes
the friction clutch p' to be automatically connected to pulley pas soon as the operator
removes the foot pressure from the treadle T..
When it is desired to produce what is termed a wax heel employ the waxing
device or wax feeder shown in Figs. 7, 8 and 9 and it consists of a tube or wax
receptacle V open in its lower end and arranged directly above the rotary burnisher
tool as shown in Figs. 7 and 8. The upper end of the tube V is closed with a
suitable cap y, having a central screw threaded perforation for the reception of the
screw e as shown in Fig. 7; the screw el has a piston or plunger " in its lower end
and a disk or handle 3 in its upper end as shown. The wax to be brought in contact
with the rotary burnisher tool ' is contained in the case V below the piston and
by turning the handle 3 more or less, the wax is forced downward and against the
rotary burnisher tool from time to time as may be required.
The tube or case V is adjustably secured to the bracket V1 that is journalled on the
the shaft and is provided with a pair of rods VV the rear ends of which are
passed through corresponding perforations in the bearing has shown in Figs. 7, 8
and 9, and by means of said rods the bracket V₁ is prevented from rotating with the
shaft ; for the purpose of holding the bracket V₁ on the shaft h in such a position
that the wax tube V shall be directly above the burnisher tool as shown in Figs. 7
and 8, I secure to the shaft on opposite sides of the brackets V₁ the adjustable
collars VV which are made adjustable on the said shaft by means of set screws or
equivalent devices.
To the rear end of the rock shaft. is secured a crank arm or lever X to which is
attached the upper end of a spring X shown in Fig. 2, the lower end of the latter
being attached to the post b or other stationary part of the machine; said spring
serves to counteract the momentum of the burnisher shaft and its adjuncts as such
parts are oscillated the device also serves to prevent the lobed gears d³, o, from
rattling during the operation of the machine and insures a more steady, uniform and
noiseless motion of the working parts.
