page_text: following statement in writing, & on reference being had to tho
accompanying Shect of Drawings, that is to say :-
The present improvements have reference to the fundamental principles
of a machine for a like purpose for which Letters Patent of the United
States of America were granted to the said Samuel Horatio Hodges
bearing date the 25th day of July, 1871, No. 117,287, the novel character-
istics of which consisted mainly in the combination with a jack or holder
for supporting the boot or shoo of a trimming or burnishing tool,
actuated by suitable mechanism, and mounted upon a flexible or jointed
frame or arms in such a manner that it may by such means be brought
to bear at any desired point or angle upon the edge or bottom of a boot
or shoo hold in or by the jack. The present improvements however
possess inherent novelty which will render their individual application
valuable to other machines of a like character, while they dopart
radically from the said machino in ono particular, viz., in the em
ployment of a stationary or straight trimming knifo in lieu of a rotary.
cutter head armed with a series of peripheral cutters.
"
Heretoforo in solo or "foro part" trimming machinery in which a
stationary knife is employed, tho jack or devico which supports and
carries the boot in the necessary path, while the knifo performs its
functions is driven in an un‹leviating path in an orbitary vertical plano.
and in one direction only, with no freedom of motion out of this path,
and no power of retracing its step if the knife execute imperfect or un-
finished work. The variable yielding motions which are requisito
between the cutter and solc in order to conform to the irregular outline
of the latter being executed by the cutter. Furthermore a form or
pattern plate has been adopted to impart the desired size and outlino to
the solo by causing the cutter to reduce to such pattern plate any portion
of the solo protruding beyond it.
Many objections are found to exist in this construction for the reasons,
among others, first, that with a pattern plate all soles of one number
aṛo reduced to a given outline without permitting the workman to
exercise his discretion in varying from this pattern as is often desirablo
owing to variations of the uppers; and secondly, that the knife owing
to the nature of its attachments, oftentimes inclines inward toward
the pattern plate, and abuts against the latter with injury to both,
and at other times diverges from such plate and leaves the leather, or

page_text: imparts an irregular and unsightly edge to the sole which remains,
as the sole cannot retrace its movement, or is remedied only by effecting
an entire circuit of such solc, and going a second time over the im-
perfect place.
100 improvements coMSHSL,"
Firstly. In applying the jack to its supporting frame or column, so
that whilst being driven in an oblong path it possesses all necessary
freedom of motion in any direction with respect to the trimming knife.
Secondly. In applying the jack and carriage which carries it, and
combining them with the driving shaft of the machino, so that by the
simple reversal of a pulloy operated by the knce of the workman or
otherwise, he is enabled to reverse the movement of the jack, or the same
and a boot or shoe applied to it, and compel the knife to retrace
its movement and pass again over any portion of the sole edge once
traversed by it and left in an imperfect state.
Thirdly. In dispensing with the form or pattern plate, and in
mounting the knife or shank in its swinging arm or frame which
supports it by means of a ball and socket or other universal joint, and
providing it with an upright handle in order that the workman by the
aid of such handle may vary the horizontal slope of the knife trans-
versely of its length, and gauge the depth and direction of its cut or
longitudinally of its length, and thus vary the angle of the sole edge,
and also adjust by such handle the proper height of the knife and
present it to the sole edge.
Fourthly. In constructing the jack so that its heel post or jaw
remains stationary in order to obtain a positivo goneral starting point
for tho work to begin, and in connection therewith in applying the
knife stock to its supporting arm, so that its position with respect to the
heel post or to the same and the heel or sole of the boot or shoe will
enable the workman to begin at the least conspicuous part of such solo,
for the reason that it sometimes occurs that a slight imperfection in the
surface is left by the initial cut of the knife.
And fifthly. In providing a means of varying the distance travelled
by the jack in its oblong path in order to adapt the functions of the
machines to soles of various length or sizes by mounting the jack upon

page_text: a travelling carriage, and providing it with a regulating screw to govern
its position upon the latter with respect to one end, turning point, or
centre of the same, a suitable scale of divisions being made upon some
conspicuous and convenient part of the said carriage, which corresponds
to the various sizes of boots or shoes in order that the workman may
readily set the "jack" to the desired point.
•
Such being the nature and object of the said Invention for "Improve-
ments in Machinery or Apparatus for Trimming or Burnishing the Edges
of the Soles and Heels of Boots and Shoes," I will now proceed to
describe more in detail the manner in which the same is to be or may bo
performed or carried into practical effect, and in order that the same may
be distinctly understood I have annexed hereunto one Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters of
reference corresponding with those in the following explanation thereof,
that is to say:-
On the accompanying Drawings Figure 1 represents a plan, Figuro 2,
a front side elevation, Figure 3, an end elevation, and Figuro 4, a
vertical section of an edgo setting machine embodying the present
improvements; Figuro 5 represents an outer side view of the plato,
rack, and channel herein-after referred to, the remaining Figures being
enlarged sections of portions of the improved machine.
A represents the bed plato or base of the machine, which is a curved
block, somewhat in the form of a hook, and provided with two foot B,
and a hollow standard O, upon which it is supported. The driving
abaft D is mounted horizontally in suitable boxes E erectod upon the
rear end of the base A, and is provided at one end with a fast spiral
worm F, and at the other with a fixed circular friction disc or truck G,
the periphery of which is reduced to two inclined or bevilled faces a of
equal angles, while disposed loosely upon the shaft and upon cach side'
of the disc G, and revolving in opposite directions, as shown by arrows
on them, is a pulley H or H', arranged so as to slide andwise in contact
with or away from the truck or disc. Each pulley H or H' is formed
with a concentrio peripheral grooved hub b, and into the groove of each
hub the end of a shipping bar c or c³ extends, the opposite ends of the
two bars being fixed to a long horizontal shipping or reversing, rod I,
which is common to the two, and which is mounted and slides” within
suitable boxes J applied to the base of the machine or making part of
the boxes E, the said rod I being parallel with the driving shaft and of

page_text: about equal length therewith. The end of the rod I immediately
adjacent to the worm F is formed with a concentric channel K, into
which extends one end of a horizontal shipping lover L fulcrumed to a
post or stud M erected upon the base A, and extending to the front
ond N thorcof, where it terminates in a fork O, in which the workman
places his knee, and by it reverses the motion of the jack at pleasure.
The worm F drives (by the means herein-after stated) the pinion which
actuates the jack supporting carriage or slide; and as this carriage
is applied so as to be driven in either direction by the pinion and the
worm a reversal of the motion of the latter will reverso the direction
travelled by the said carriage. The pulleys H, H', and the intermediate
truck G constitute the means of reversing the motion of such worm, and
to effect such result the workman has merely by an effort of his knee to
push the lever in one or the other direction, which drives one pulley, as
the case may be, in contact with the truck G, and rotates the worm in a
corresponding direction. A reverso pressure of the knee upon the
lever L forces the other pulley in contact with the truck G and produces
a rotation of the worm in the opposite direction to tho above. The
reversing mechanism thus arranged constitutes the second part of the
present improvements.
The jack which receives and supports the boot, and presents its sole
to the action of the shaving or trimming knife is represented at P as a
circular disc Q mounted vertically upon a plate R, and provided with
two jaws or posts S, T, the former being the heel post and stationary
upon the disc, and the latter being movable toward and away from it.
As the jack imperfectly represented by the disc Q and jaws S, T, is the
same as the pulley shewn and described in Letters Patent of the United
States granted to the said Samuel Horatio Hodges, bearing date the
19th day of March 1872, No. 124,744, and as an addition of any portion
of it to this machine is merely to define its position with respect to the
other members of such machine, its detailed constitution is not shown
or described, but it should be observed that the heel post is to bo
stationary upon the disc, in order, as before promised, to obtain a uniform
and positive starting point for the beginning of the work, and in so doing
carry out in part the object of the fourth portion of the present improve-
ments.
The plate R which unholds the inak is an aldanm

page_text: shelf groove, one which permits the jack to slide longitudinally upon
the plate, which is formed or provided at its outer face with an oblong
chamber V, the sides of which are parallel, and the ends of which aro
semicircular, the boundary thereof being formed into a toothed rack W
which extends its entire circuit, while in the inner face of such chamber
is cut an endless channel X of a contour exactly corresponding to that
of the toothed rack W, but of a size somewhat less, as represented in
Figure 5. The plate R and rack W is mounted and slides upon a
second plato Y of similar form and size, pivotted at its centro to a tilting
block or cross head Z which is pivotted by a horizontal pin d to tho
upper end of an L shaped standard e, the lower end of which is pivotted
to a stud a' which is adjustably conncoted to a sliding carriage playing
in horizontal reciprocations within a grooved head g, which is affixed to
the upper part of an upright post crected upon the front end of the
baso A.
Suitable springs a aro combined with the carriage fand head g so
as to force the former outward or away from the trimming knife, and in
order to advance such carriage and present a boot carried by the jack to
the action of such knife a treadle is employed and disposed within the
standard C, and connected with the outer end of the carriage ƒ by a
cord; which passes over a pulley k pivotted within the post h, as repre-
sented in Figure 4. Within the plate Y is mounted a short horizontal
shaft or stud 2 which extends across the chamber V and enters tho
channel X, and upon the portion of this shaft which crosses this chamber
is affixed a pinion m which gears into the rack W, and serves to drivo
the plate R and chuck in an oblong path upon the inner face of tho
plate Y, while the channel serves to properly support and guido such
plate R in its movements, and relieves the pinion of the thrusts and wear
which would otherwise devolve upon it. Upon the outer end of the
shaft / I affix a bevilled gear p, while gearing therewith and driving it
is a second bovilled gear 9, which is affixed to the inner end of a hori-
zontal shaft which rotates in suitable bearings applied to the block or
cross head Z, the outer end of such shaft being provided with a bovilled
gears which gears into a twin goar Zaffixed to the upper extremity of
an upright rod v which rotates within a bearing w, forming part of a
bracket & which projects from the rear end of the cross head Z. Tho
lower part of the rod o terminates in a forked block y which constitutes
ono portion or gimball of a universal joint al, the lower gimball or fork 6¹

page_text: of which is attached to, or makes part of, the upper end of a rod c¹
which enters and slides within a tubular bar d', the lower end of which
is connected by a universal joint e³ with a worm gear f¹mounted upon an
upright post 9' affixed to the base A, and in such close proximity to the
worm F as to gear into and be driven thereby. The rotation of the
shaft D acting through the universal joints a¹ and e', the bevilled gears
P. 9, 8, and 1, with their adjuncts, and the pinion m, and rack W, drives
the plate R. and jack through a path corresponding to the form of the
insido rack W, such path being the proper one to carry the boot sole
about the trimming knife, and obtain one of the free or variable motions
herein-before named as constituting the first portion of the present
improvements. The pivotting of the standard e and its super-disposed
load to the adjustable stud a* allows a horizontal movement in a circular
path to be imparted to the jack, and provides another of the said free
motions. The pivotting of the cross head Z to the standard e and the
horizontal sliding of the carriage ƒ insure liberty of motion, which, in
conjunction with those last named, gives all desired liberty to the
motions of the jack, and completes the said first portion of the present
improvements. By the freedom of motion thus obtained all necessity
for a pattern plate or form is dispensed with, and thus is carried out in
part the intent of the third portion of the present improvements.
Having thus seen how the boot is supported and carried through the
motions necessary to effect the trimming of the sole, the nature, appli-
cation, and operation of the knife by which the same is exccuted will be
next explained.
A represents an upright frame or standard of any suitable design
disposed preferably above the driving shaft, and bearing at its top a
horizontal arm or frame B¹ which is pivotted to it so as to oscillate or
rock thereupon in a vertical plane, a suitable catch or stop action being
applied to the two to uphold the knife-carrying end of the arm B¹, and
relieve at certain times the operator from this labour, assuming such end
of the arm to be the heaviest as would ordinarily be the case. The front
and free end of the knife carrying the arm B¹ projects forward to a
point about opposite the centre of the carriage fand the heel rest of the
jack when the latter is in the position which it should assume at the
initiatory action of the knife upon the sole, and it is preferred that this
initial action of the knife should be as before premised at the shank
immediately up to the heel, as this is the portion of the sole edge where
9

page_text: any imperfection would be less apparent than at any other. This
however is by no means arbitary, as no imperfection may result from
the action of the knife at the starting and leaving-off points.
.
Another advantage in starting the action of the knife at the inner
face of the heal is that in this caso it will not be necessary to compol
tho jack and its plate R to describe a movement about but one end
thereof. The trimming knifo or tool is represented at C' as composed of
two portions, one D' being a bar, the outer end of which terminates in a
right angular bond or lip which serves as a guide to the knifo by
travelling in the rand scam of the boot, and the other portion k³ a paring
or trimming blade for reducing the edge of the sole to an even surfaco,
the two parts D' and ¹ being enclosed within a tubular holder ♫ formed
with a ball m³ which is received within a socket n¹ made in the front or
free extremity of the arm B³, the ball and socket or universal joint thus
obtained permitting the greatest freedom of motion to the knife by
allowing it to tilt or slope in either a vertical direction longitudinally of
the frame B' or horizontally and transversely thereof, and in so doing
govern as before stated the depth of the cut affected by it, and to a
certain extent when desired vary the bevil or angle of the sole edge.
Theso motions of the knife are controlled by an upright handle o' which
is screwed into the ball m³ so as to abut against the two portions of such
knife and clamp them tightly together. The vertical variations of the
knife is an important matter for the reason, among others, that with soles
of varying widths or sizes tho knife-carrying arm must be raised or
lowerod, consequently tho slope of the knife must bo variod in con-
sonance therewith, for if rigidly attached to the arm it would under
certain conditions take too rank a cut into the leather, and oftentimes
leave it altogether.

page_text: bodily back and forth with respect to the jack and boot, and to accom-
plish this the knife and its holder is inserted within a stock E attached
to the arm B by a tenon and socket joint provided with a set scrow.
It might under some circumstances be found desirable to impart as
shown in my Letters Patent of the United States of America, E
No. 117,287, before referred to, a vibratory motion to the standard or
frame A' in combination with the herein described free motions of tho
jack, but such motion of the standard A' would in this connection
doubtless be found superfluous. As the plate R travels in a given path
at all times, and the jack is caused to slide upon it for the purpose of 1
adapting the machine to soles of varying lengths, the extent of sliding
of the jack to and fro of such plate is controlled by a screw F' which
screws into the base of the jack so that its head p' shall intercept and
constitute a stop to such plate. By increasing the relative distance
between the heel post of tho jack and the opposite end or turning point 1
of the plate R, tho time during which the sole travels below the knifo is
prolonged, and vice versa, and this relative distance is properly calculated
and proportioned with respect to the length of the sole in order that when
the semicircular end of the rack W reaches the pinion m, and tho jack
begins by the aid of such pinion to describe a semicircle with the pivot 2
of the plate Y as a centre, the too of the sole shall reach the knife and
begin to describe a like movement below it.
•
As an aid to the workman, and to enhance the utility of the machine
as before premised, a suitable scale of divisions is engraved upon some
conspicuous part of the carriage or plate R, which are graduated to 2
correspond to the various sizes of soles, and constitute a means of
enabling the workman to instantly adapt the jack to any given size.
In the employment of the screw F³, or its equivalent, and the functions
performed by it, as well as in the scale of divisions employed as an
auxiliary to such screw, are included the fifth and last portion of the 8
present improvements.
In describing the operations of this machine I will supposo, as a
starting point, that a boot is applied to the jack, and the latter stands in
the position represented in Figuro 1, in which case the trimming knife or
tool stands at the inner edge of the heel of the boot, and with its guiding 3
lip entering the rand seam thereof, tho two pulleys II, H', revolving in
the directions indicated by their respective arrows, and the plates R and

page_text: Y in a horizontal position. The workman, by means of his right knco
and the shipping lever L, engages the pulley II' with the disc or truck,
G, and puts the shaft D in rotation in the direction travelled by such
pulley, which rotation through the agencies, herein-before described,,
starts the jack in company with the plato R in motion in a horizontal
path in the direction of the arrow placed on such plate, it being under-
stood that the horizontal variable movement of the arm B' enables the
workman to adapt the knife to the longitudinal curvatures of the solo
edgo, in connection with the rotary or oscillating motion of which the
combined plates R and Y are susceptible about the pivot of the latter as,
a centre. Simultaneously with the movement of the shipper L, tho.
workman clevates the knife above the lovel of the upper edge of the
sole, depresses the treadlo i to such an extent as to advanco tho solo edge.
below the knife, and then lowers the latter until its lip or guido h¹ enters
the rand scam of the boot. The jack and plate R continue to travel
rearward in the direction indicated and carry the sole edge in a liko
direction in contact with the knife by which it is trimmed, the slope or
angle of such knifo in either direction, or its height bodily, being varied
and adjusted as the workman finds necessary in the progress of the work.
The jack and carriage R with the boot continue the journey in the
direction stated until the semicircular portion or end of the rack W
reaches the pinion 'm, and the too of the sole at the same time reaches
the knife. The jack and the plates R and Y now turn in unison in tho
arc of a circle upon the pivot of the latter as a centre, and as a conse-
quence the too portion of the solo is carried about in contact with the
knifo and trimmed by it, the rotation of the jack and plates continuing -
until the position of all are reversed upside down and a horizontal.
position again assumed. By the action of the pinion m upon the rack
W, as before stated, the jack and the two plates begin a rearward move.
ment in a horizontal plano until the front edge of the heel arrives at the
knife, when the trimming of tho solo is completed, the motion of the
jack stopped, and the boot removed.
ป
Preparatory to "jacking" another boot and renowing the functions of
the machine, the driving shaft is, put in rotation in the direction and by
the means first stated, until the jack and two plates have described
another semicircular movement by the action of the pinion upon the
endless rack W, which brings the said jack and plates to the position.
first, assumed and in readiness for the application of a boot. If tho
+
•

page_text: knife, in once going over and acting upon the sole edge fail for any
reason to properly trim the latter the motion of the sole may be reversed
by reversing the position of the shipper L and by it of the pulleys H, H³,
and such sole compelled to retrace its journey sufficiently far to bring
the knife in advance of the imperfect place when the motion of the
driving shaft is again reversed and the knife goes again over the imperfect
place. A suitable catch or locking device is contrived with the screw F
and the plate R, to prevent the sliding of the jack upon the latter at the
wrong time, and a suitable abutment or stop ³ is also formed thereupon,
adjacent to the head of the screw, against which the contiguous end of
the base of the jack is to be placed when beginning operations upon a
solc. Upon a new size of boot sole being introduced to the machine the
screw is set to the point indicated by the scale for such size, and the jack
pushed up against the stop as stated. The driving shaft being put in
rotation the sole, abutting against the knife, has the effect of sliding.the
jack upon the plate R until the head of the screw brings up against the
stop "", at which time the jack and boot have reached a point where they
will turn when the proper time arrives on a common contre with the
plate Y and carry the toe of the solo about below the knife.
'
Although the foregoing description of this machine relates to its
application and use as a trimming machine, it may be adapted to the
purposes of burnishing by substituting for the knife a cylindrical disk of
proper form, and revolved by suitable means; and the transferring of the
two may be effected by removing the arm B¹ and adding in its place one.
carrying a pulley, which may be driven by a second pulley fixed to the
driving shaft.
Having now described the nature and object of the said Invention for
"Improvements in Machinery or Apparatus for Trimming or Burnishing
the Edges of the Soles and Heels of Boots and Shoes," together with the
manner in which the same is to be or may be performed or carried into
practical effect, I would remark in conclusion that I claim as tho
Invention communicated to me by the said Samuel Horatio Hodges,-
Firstly. In machinery or apparatus of the kind specified, the com.
bination of a "straight" or stationary knife (in contradistinction to a
rotary one) and a jack actuated to travel in a path which will bring to
or under the knife those portions of the boot or shoe to be acted on, and.
capable also of movements substantially as set forth, independent of that.
