1, SETH DEXTER TRIPP, of Lynn, County of Essex, State of Massachusetts,
United States of America, Inventor, do hereby declare the nature of this invention
to be as follows:-
This invention relates to edge finishing machines adapted for finishing the edges
of the soles of boots and shoes.
In accordance with this invention the edge finishing tool is mounted upon an
oscillating shaft, which is carried by an oscillating frame, so that the tool has
imparted to it an oscillating movement on its own axis in addition to a vibrating or
Oscillating movement on the axis of the frame carrying it.
The edge finishing tool is provided with a plurality of working facos, and means
are provided for adjusting said tool while in operation, to bring any one of its
working faces into working position.
A friction heating device is provided for the edge finishing tool which comprises
friction plates bearing directly against the opposite sides of the tool, and means
being provided for holding said plates in such frictional engagement.
The shaft carrying the edge finishing tool is adapted to be raised, or to yield in
a vertical direction, and the tool is also adapted to yield in a longitudinal direction
on the shaft which carries it.
The main frame is of suitable construction to support the operating parts. The
main shaft has its bearings in said frame, and has a driving pulley mounted upon
it. Formed upon the end of the shaft is a crank-pin, or eccentric which receives
upon it a box. The crank-pin is free to rotate in the box, but as it turns said box
is moved to correspond with the travel of the crank-pin.
The box is fitted to work within the bifurcated upper end of a pivoted arm as
for instance it may project from a sleove placed upon a stud or rod, which serves
as a pivot on which said arm vibrates.
The sleeve has depending from it a frame which serves as a bearing or support
for the bearing box, which is bored to receive a shaft.
The bearing box and shaft are arranged obliquely, and the rear end of said
oblique shaft has formed in it a socket which receives a spherical stud, secured to
a rearwardly projecting portion of the frame.
A spring is interposed between the bearing box and the sleeve, the tendency of
which is to depress said bearing box and parts borne by it, yet permitting said
box to yield in an upward direction when it is desired to raise the edge finishing
tool which is placed upon the oblique shaft.
The edge finishing tool is made as a hub adapted to be placed upon the forward
end of said shaft, bearing against a washer also placed, on said shaft, which latter
in turn bears against a spring, likewise placed upon the shaft, and next to the
front end of the bearing box, so that said spring is interposed between the bearing
box and the washer, and acts to permit the edge finisbing tool to yield longitudinally
on the shaft.
The edge finishing tool is splined on to the shaft and is thereby permitted to
move longitudinally thereon.
A washer is placed on tho oblique shaft next to and bearing against said edge
finishing tool, and a strong flat spring is attached to the rod which is bent more

page_text: or less U-shaped and provided with a bifurcated end, which embraces the shaft
and bears upon the washer.
The washers on either side of the tool are held from turning with the shaft and
for simplicity there may be a pin on the depending arm, which projects from and
enters a slot formed in the washer, and a pin on the washer which projects forward
and enters a slot in the flat spring.
The spring bearing against the washer at one side of the edge finishing tool,
and the other washer bearing against the edge finishing tool at the opposite side,
serve as a friction heating device.
As the main shaft revolves, the arm is vibrated, oscillating the sleove on the
rod, and correspondingly oscillating the depending frame and consequently the
edge finishing tool.
The edge finishing tool thus travels in the arc of a circle about the said rod as a
centre.
The edge finishing tool has a plurality of working faces, in the present case
being provided with four, each differently formed, yet it is obvious that it may
have as many as desired.
In practice it is frequently necessary to adjust said edge finishing tool while it
is operating, to bring a different working face into working position, and to
accomplish this result a toothed gear is secured to the tool-carrying or oblique
shaft, which is engaged by a toothed pivoted sector provided with a land lever by
means of which it may be turned on its pivot.
A quadrant is fixed to the main frame having as many notches as there are
working faces on the edge finishing tool, and the hand lever has a locking detent
adapted to enter any one of the notches, and thereby hold the pivoted sector in
different positions.
It will be seen that by disengaging the locking detent, and turning the pivoted
sector, the toothed gear will be rotated to turn the tool-carrying shaft, and
consequently the tool which is splined thereon.
This adjustment may be made while the edge finishing tool is in operation,
notwithstanding it may be operating very rapidly.
The toothed gear and toothed sector also enable another most important function
to be performed, namely, to oscillate the tool-carrying shaft on its axis, and
consequently impart to the edge finishing tool an oscillatory motion, for it will be
seen, that ns the toothed sector is held at rest whenever the frame carrying the
tool-carrying shaft oscillates in one direction, the toothed gear will be rotated one
way, and as the frame oscillates in the opposite direction, the toothed gear will be
rotated in the opposite way.
Thus it will be seen that the edge finishing tool has an oscillating movement on
its own axis in addition to the vibratory or oscillatory movement of the frame
carrying it.
The pivoted sector instead of being utilized as a co-operative part of the group
of mechanism adapted to perform the double function, above set forth, may be
secured permanently to the frame, and the hand lever and locking devices omitted,
in which case the edge finishing tool will be oscillated as the frame oscillates, but
it cannot be adjusted to present different working faces into working position.
With a machine constructed in this latter way, the edge finishing tool, if
provided with a plurality of working faces, may be adjusted in any well
known way.
Therefore I desire it to be understood that I do not desire to limit my invention
to the particular means herein described for imparting independent oscillatory
motion to the oscillating tool.

page_text: Improvements in Edge Finishing Machines for Boots and Shoes.
I, SETHI DEXTER TRIPP, of Lynn, County of Essex, State of Massachusetts,
United States of America, Inventor, do hereby declare the nature of this invention
and in what manner the samo is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to edge-finishing machines adapted for finishing the edges
of the soles of boots and shoes.
In machines of this class the edge-finishing tools have been moved back and
forth, as for instance they have been oscillated or reciprocated. For the production
of good work it is necessary to oscillate or reciprocate the edge-finishing tool very
rapidly, and when the tool is so driven it will vibrate or jar the shoc and
consequently the hands and arms of the operator holding it, such action being due
mainly on account of the irregular form or curvature of the shoe sole.
This invention has for its object to vory materially reduce this vibration or jar
incident to rapidly operating the tool in the manner above referred to, and the
invention consists in giving to an oscillating edge-finishing tool or one moving
rapidly back and forth, an independent back and forth movement so that it will
advance or move along the work in each direction as it oscillates.
In carrying out this invention I provide a frame and means for moving it
rapidly back and forth, and upon said frame I mount the edge-finishing tool, and
provide means for moving said tool back and forth in unison with the frame. The
tool will preferably be moved back and forth in the arc of a circle, while the frame
carrying it may be vibrated or moved back and forth in auy desirable manner so
long as the parts operate in unison. The tool may not only be oscillated in unison
with the back and forth movement of the frame carrying it, but also moved in a
like direction. As herein shown the edge-finishing tool is mounted upon an
oscillating shaft which is carried by an oscillating frame, so that the tool has
imparted to it an oscillating motion on its own axis in addition to a vibrating or
oscillating movement on the axis of the frame carrying it.
The edge-finishing tool is provided with a plurality of faces, and means are
provided for adjusting said tool while in operation to bring any one of its working
faces into working position.
A friction heating device is provided for the edge-finishing tool which comprises
friction-plates bearing directly against the opposite sides of the tool, means being
provided for holding said plates in such frictional engagement. The shaft carrying
the edge-finishing tool is adapted to be raised, or to yield, in a vertical direction,
and the tool is also adapted to yield in a longitudinal direction on the shaft which
carries it.
In the accompanying drawings:
Figure 1 shows in side elevation an edge-finishing machine embodying this
invention;
Figure 2, a right-hand end elevation of the same, the friction heating device
being removed;
Figure 3, vertical section of the machine, taken on the dotted line x-x,
Figure 1;
Figure 4, a detail to be hereinafter referred to.
The main frame A is of suitable construction to support the operating parts.
The main shaft a has its bearings in said frame, and has a driving-pulley a
mounted upon it. Formed upon the end of the shaft a is a crank-pin or
eccentric a which receives upon it a box a'. The crank-pin is froo to rotate in
the box, but as it turns said box is moved to correspond with the travel of the

page_text: crank-pin. The box a' is fitted to work within the bifurcated upper end a* of
a pivoted arm a', as for instance, it may project from a sleeve a', placed upon
a stud or rod a', which serves as a pivot on which said arm vibrates. The sleeve a
has depending from it a frame b, which serves as a bearing or support for the
bearing-box which is bored to receive a shaft . The bearing-box b¹ and
shaft are arranged obliquely, and the rear end of said shaft has formed in it
a Booket which receives a spherical stud 2, secured to a rearwardly-projecting
portion of the frame 6. A spring 3 is interposed between the bearing-box b¹ and
the sleeve a', the tendency of which is to depress said bearing-box and parts borne
by it, yet permitting said box to yield in au upward direction when it is desired to
raise the edge-finishing tool c, which is placed upon the shaft. The edge-finishing
tool c is made as a hub adapted to be placed upon the forward end of said shaft 6³,
bearing against a washer &, also placed on said shaft, which latter in turn bears
against a spring 6, likewise placed upon the shaft and next to the front end of the
bearing-box 6', so that said spring is interposed between the bearing-box bl and the
washer and acts to permit the edge-finishing tool to yield longitudinally on
the shaft. The edge-finishing tool is splined onto the shaft 6 and is thereby
permitted to move longitudinally thercon. A washer d is placed on the shaft b
bext to and bearing against said edge-finishing tool, and a strong flat spring e is
attached to the rod a, which is bent more or less U-shaped and provided with
a bifurcated endel which embraces the shaft and bears upon the washer d. The
washers and d are prevented from turning with the shaft, and for simplicity there
may be a pin 10 on the depending arm, which projects from and enters a slot
formed in the washer b, and a piu 12 on the washer d, which projects forward and
enters a slot in the flat spring. The spring e, bearing against the washer d at one
side of the edge-finishing tool, and the washer &, bearing against the edge-finishing
tool at the opposite side, serve as a friction heating device.
As the main shaft a revolves the arm a is vibrated, oscillating the sleeve a on
the rod as, and correspondingly oscillating the depending frame b, and consequently
the edge-finishing tool. The edge-finishing tool, thus moves back and forth in the
arc of a circle about the rod a' as a centre.
The edge-finishing tool has a plurality of working faces, it being herein
represented as having four, cach differently formed; but it is obvious that it may
have as many as desired. In practice it is frequently necessary to adjust said edge-
finishing tool, while it is operating, to bring a different working face into working
position, and to accomplish this result a toothed gear is secured to the tool-
carrying shaft b, which is engaged by a toothed sector f' mounted on the rod a³
and provided with a hand-lever f, by means of which it may be turned on its pivot.
A quadrant is fixed to the main frame, having as many notches as there are
working faces on the edge-finishing tool, and tho hand-lever has a locking-detent
adapted to enter any one of the notches, aud thereby hold the pivoted sector in
different positions. It will be seen that by disengaging the locking-detent and
turning the pivoted sector the toothed gear will be rotated to turn the tool-carrying
shaft, and consequently the tool which is splined thereon. This adjustment may be
made while the edge-finishing tool is in operation, notwithstanding it may be
operating very rapidly.
b
The toothed gear and toothed sector also enable another most important function
to be performed, namely, to oscillate the tool-carrying shaft on its axis, and
Consequently impart to the edge-fiuishing tool an oscillatory motion, for it will be
seen that, as the toothed sector is held at rest whenever the fraino 6 carrying the
tool-carrying shaft, oscillates in one direction, the toothed gear will be rotated one
way, and as the frame oscillates in the opposite direction the toothed gear will be
rotated in the opposite way. Thus it will be seen that the edge-finishing tool has
an oscillating movement on its own axis in addition to the vibratory or oscillatory
movement of the frame carrying it, and as a consequeuce the edge-finishing tool
will act or work upon the sole-edges as it is bodily moved in each direction along
said sole-edge thus having a compound vibratory movement. It will also be secu

page_text: that, as heroin shown, the back and forth movements or oscillations of the tool are
in unison with the back and forth movements of the frame carrying it, and also in
a like direction.
The pivoted sector instead of being utilized as a co-operative part of the group
of mechanism adapted to perform the double function above set forth may be
secured permanently to the frame and the hand-lever and locking devices omitted,
in which case the edge-finishing tool will be oscillated as the frame oscillates, but it
cannot be adjusted to present different working faces into working position. With
a machine constructed in this latter way the edge-finishing tool, if provided with a
plurality of working faces, may be adjusted in any well-known way.
I desire it to be understood that I do not wish to limit my invention to the
particular means herein shown for imparting independent oscillatory motion to the
Oscillating tool; and furthermore, believing myself to be the first to provide an
edge-finishing machine with a tool-carrying frame and means for moving it back
and forth or oscillating it, and providing means for moving the tool carried by said
frame back and forth or oscillating it independently of, but in unison with, the
back and forth movements of the frame, I desire it to be understood that such
features come within the spirit and scope of this invention.
