page_text: serving as a support for the lock B³ and also as a convenience for attaching
other parts.
Near the top of the supporting post B a four armed turret or
swiveling head.b is mounted. The four arms of the turret are indicated in
Figure 2 by B B B B' and serve as supports for trees C upon which the shoes
to be treated are to be placed.
D is a bent lever one arm of which passes through the shackles D' of the trees
to spread them and so hold them as required for holding and moving up the shoe to
be treed. The lower end of the bent lever D is provided with a spring operated
pawl D (Figure 1) which is adapted to engage with a curved ratchet D and thus
hold the lever in place; and though the said lever and the shackles hold the shoe
it is to be understood that there is one of these devices attached to and moving
with each arm of the turret, or as many as there are arms, which need not be
limited to four as more may be used if thought desirable. There are two, sets of
stationary levers for operating the bent shackle lever D one set for the operator
who places the shoe on to the tree, and one for the operator who takes it off when
finished. I will now describe one set of these levers. D is a foot lever pivoted
at D' (Figure 5) and held up by the spring d. D' is a link connecting the lever D
to the lever D the lever D being adapted to act upon the under side of the shackle
lever D and cause it to act upon the tree as has been described. To release the
shackle lever D' we have a second foot lever D' which is mounted upon the
lever D so that it moves in unison therewith with its foot piece a little above
the foot piece of the lever D during the act of spreading the tree.
When the two
foot pieces are brought into line by the foot of the operator the shackle lever D
is free to move backward as desired. The lever D' has a link D10 which connects
it to a let-off lever D" that has a bevelled edge D" adapted to move back of the
pawl D and thus release it and the shackle lever D' from the ratchet D° and
unjacking the shoe. The let-off lever D" is held back by the spring D". When
the turret, with the trees spread, is stopped at the proper place, two of the
shackle levers will be located above the let-off levers, that is in position to be noted
upon by them.
The turret head arms are held in the desired position by the following device
(see Figures 2 and 2B). Two locking bolts B" B1 are arranged to slide vertically
in the lock B being thrown up by springs B B their upward motion being
limited by fixed pins B B; the upper ends of the bolts B13 B¹³ engage with
shoulders B B formed on the under side of the arm, (see Figure 2B) and lock it
into the desired position the bolts B13 are operated by a hand lever B¹ said hand
lever being connected to the bolts by pivot pins B" B". By depressing the lever
the right hand bolt is withdrawn and the turret head may be turned to the right.
By lifting the hand lever the left hand bolt is withdrawn and the turret head
may be turned to the left. The fixed pins B B act respectively as fulcrums for
the lever B¹¹
Each of the turret arms is provided with a tree-socket piece C₁; this socket
piece receives the tree and is normally free to turn on its horizontal axis, except
when the tree is in the position which it occupies while the shoe that it holds is being
treed; then it is held firmly by the following described device. Each of the
turret arms is provided with a clamping lever B' pivoted to the ears B10 by the
pin B". The inner end of the clamping lever B' is forced upward by the action of
the upper end of the shackle lever D', this action taking place when the shackle
lever holds the shackle in tension forcing the inner end of the clamping lever up,
and causes the outer end to press firmly against the tree socket piece C¹ and to hold
it and the tree in place.
For convenience in centering or adjusting the tree and the shoe on the turret
arm, I have a rod C² (Figure 5) made with a fork at one end which embraces the
shoe near the toe end and thus acts as a guide for holding it accurately in place
until the tree is clamped or otherwise made fast to its turret arm. The rod C²
passes freely through the swivelling housing C³ attached to the upper end of the
post B. The attachment being such that the rod is always held accurately in the

page_text: vertical plane that passes through the centre line of the tree and the shoe. But it
is free to swing upward and also to slide longitudinally.
The treeing tools and their connecting and operating mechanism may be described
as follows:-
The standard F (Figures 1, 3 and 4) is firmly attached to the bed plate A and
serves as support for the working parts. The main driving wheel F¹ has a shaft F
said shaft having a gear wheel which meshes with the gear wheel F on the
shaft F and serves to transinit motion through the gear wheel F' acting through
the gear wheel F; a clutch mechanism transmits motion to the shaft K.
The clutch mechanism above referred to and its connection with the starting and
automatic stopping apparatus is peculiar, and will be fully described in another part
of the Specification.
The lower tool apparatus consists of a sliding bracket H* (Figure 1) and is moved
up and down (in properly constructed ways formed on the standard F) by the crank
arms H, on the shaft H, the cranks H₁ operate the bracket H by means of the
links H pivoted to the bracket H' at H. The spring H' serves as a counter
balance for the weight of the lower tool apparatus and acts through the links H',
levers H' and links H³, the links H being connected to the levers H' so that the
springs H will exert substantially the same balancing strain upon the sliding
bracket H* regardless of the springs tension. The tool holder T is made to slide
longitudinally on the bracket H' by means of a ratchet crank disc T'. This crank
disc has a crank pin 18 which works in a vertical groove formed in an adjustable
extension T of the sliding tool holder T, and as the ratchet crauk disc rotates the
tool holder T and all of the tools T1 T2 T3 T4 are made to move back and forth
horizontally. The rotation of the crank disc T' is effected by the fixed pawl T
with which the disc comes in contact at the extreme upper part of the vertical
movement of the tool apparatus.
The sliding tool holder T has mounted upon it tool standards T' one at each side.
These standards have at the top a tool proper which operates at and near the
rand line of the shoe. These standards are united by swivel joints at t² to the
part so that the tools t¹ can swing to and from the rand line. These tool
standards Tare adjustable vertically in these joints 2 and the joints are provided
with springs in pockets formed at the upper ends of the parts which press these
standards and of course the tools t' towards the sole of the shoe as far as the joint t*
will allow so that at certain stages of the rubbing of the shoe the tools will operate
next the rand line as will be hereinafter described (see Figures 1, 3).
The extensions & carrying the joints are pivoted to the tool holder Tat¹
Figure 4, so that the tools t can swing to and from the shoe and it will be under-
stood that the compression spring at twill have a tendency to force the lower
extension parts to outward and, as a consequence, force their upper ends to which
the tools proper t¹ are attached inwardly, that is against the shoe. The pair of tool
standards TT are arranged substantially and operate to and from the shoe in the
same manner as the pair T' T' just described, but have only one joint, which
connects them to the tool holder T. These standards T2 T2 are located so that
they can pass under the standards T T when they are moved fully back by the
rand guide and when the tool holder T is moved to its nearest position to the
standard F. The pair of tool standards Ts Ts are swivelled in substantially
the same manner and have the same extension bars as the pair T¹ T'.
T (Figure 3) is a screw nut firmly secured to the tool slide T so that it will
reciprocate therewith. A screw shaft T is fitted to rotate freely in the nut T¹²
and the inner end of the screw shaft is reduced in size and fitted to the sliding
carriage T so that when the screw T is revolved in either direction the carriage
will move horizontally upon the tool slide T. The carriage T's has projecting
arins T in which are mounted (adjustable for height) the studs T18 and through
5. the top of these studs are placed the horizontally adjustable eye bolts T which
engage with and carry one end of the links T The other, ends of the links Tu

page_text: ศ
being similarly connected to the sleeves T20 which are vertically adjustable upor
the tool standards T T the parts T T T and T forming an adjustably
universal joint which allows the tools t¹ carried upon the standards T T free
motion towards the centre of the shoe tree and at the same time moves them
longitudinally thereon by the revolution of the screw T and also provides means
whereby the motion of the tool faces can be adjusted to any given angle or vamp
without changing the pitch of the screw T¹.
To the outer end of the screw shaft T" is fixed the gear wheel T and the
vertical reciprocation of this gear wheel upon the rack standard Te gives the
desired horizontal reciprocation to the carriage T for operating the vamp line
tools in addition to the horizontal reciprocation given to the tool holder T and
everything connected therewith for feeding purposes.
The tool carrying slide T is reciprocated horizontally once for each shoe treed
and the rubbing tools move over the surface operated upon in different vertical lines
at each vertical reciprocation thereof. At certain positions of the feeding the tools
carried by the standards T3 Ts pass under those carried by the standards T* T* and
both sets pass under those carried by the standards T¹ T
It is not essential that the several rubbing tools above referred to should have
the exact connections and swivelling arrangements shown in the drawings, as in
actual construction the details may be varied therefore I do not think it requisite
to describe accurately the details of their construction. The essential features are,
that the tools shall be so arranged and connected with actuating devices that they
shall be free, in their several motions, to accommodate themselves to the varying
surface of the shoe upon which they act.
The tool holder T carries a special device 'T' (see Figures 1 and 1^) for working
upon the heel part of the vamp which may be described as follows: t is a standard
to which one end of a strap t is attached the other end of this strap being attached
at to the upper end of a hollow cylinder to. This hollow cylinder is mounted
upon a standard t' upon which it is free to slide and is held up by a spring 10
The action of this tool is as follows:-As it moves upwards the strap ¹ comes in
contact with the heel of the vamp and in its continued upward motion the end of
the strap t, which is attached to the standard t, is forced to go up and to allow
this to take place it is evident that the other end of the strap that is the end
attached at to, must be forced relatively downward; this being allowed by the
movement of the hollow cylinder t; and as the end attached to the standard to is
moving upward in relation to the shoe, it is evident that the strap t" must be
sliding with a rubbing friction around the convex part of the heel part of the shoe.
Thus it does its rubbing work or treeing. This strap may be plain or carry
leather, wood or metal rubbing tools according to the kind of leather to be
operated upon.
The set of tools T T adapted to do the work near the rand has special
guides RR, which acting against the projections t" (Figure 1) cause the rubbers
very nearly to follow the rand line of the shoe, the springs in the pockets 18 holding
the projections t¹ against the formed edges of the rand guides when the conditions
of feeding the tools allow them to do so. The guide pieces R (Figures 1 and 3)
are pivoted at R¹ to a projection R* and may be adjusted for different sized shoes
by having the upper end swung in or out. The guiding edge of each guide piece R
is made as near as it is practical to make an edge that shall be approximately
correct for all sizes of shoes.
By swinging the upper end of the guide piece in or out the guides will become
practically correct for all sizes of shoes. The adjustment of the upper end is
effected automatically by the following described device. R is an arm extending
obliquely from the standard F (see Figures 1, 4 and 10) and has pivoted to it an
inclined foot piece R³ which is located in the path that the toe of the shoe traverses
when the shoe is on the tree and being swung around by the operator to bring it
into position for being treed, and as this foot piece R³ normally hangs so low that

page_text: the toe of the smallest shoe will just pass under without lifting it, it may be seen
from the following description that for the shortest shoe the upper end of the
guide R will remain in its normal position.
When a larger shoe is being put into position, its toe will come in contact with
the foot piece R³ and force it upward; this action will, acting through the
standard R, arm R and hooked rod R R lift the end R' of the segment ratchet
lever R R and as this segment ratchet lever R R has a pin at which engages
with an inclined slot R in the upper end of the guide R, it will throw the upper
end of the said guide R forward that is towards the shoe, the amount of forward
movement thus given to the guide R will depend upon the size of the shoe. The
segment ratchet lever R R is held in place by a bent lever pawl R¹³ which
engages with ratchet teeth formed on the segment end R of the segment ratchet
lever R R as shown by dotted lines in Figure 1, and in full in Figure 10.
The device for releasing the pawl lever R consists of a releasing lever R
(Figures 4 and 10); this releasing lever R" has an inclined hook at its upper end
which engages with an incline R formed on the end of the bent lever pawl R's and
as the upper end of the releasing lever R" is thrown to the left by the cam N
(Figures 8 and 10) which acts upon the lower end of it (when the machine is
stopping) this movement by a wedge like action on the incline R" will depress it
and throw the pawl end out of engagement with the ratchet on the segment ratchet
lever R³ R¹ and a spring around the shaft operating the opposite rand guide returns
the parts to their normal position ready to start again.
The tools LL and M, (Figures 3, 4, 6, 6^ and 7) tree the toe part of the shoe
and are attached to a sliding head K by pivots & as shown (Figure 7). Each of
the tool shanks L is firmly attached to a swing piece L' L, each of said swing
pieces being provided with a motion limited by the screw bolt L and a retractile
spring L'. The lower ends of the tool shanks La are provided with a rubbing tool L'
adjustably held by a pin 13 and a spring L³. The sliding head K is attached to a
bracket K³ (Figures 1 and 3) which receives its up and down movement from the
link K and crank K¹ as shown.
The sliding head Ke is held to the bracket K³ by means of the screw pivot
bolt K (Figures 1 and 6) and the screw guide flanged piece k. This flange piece
is screwed into the bracket K³, the screw pivot bolt K passing through it. This
screw pivot bolt K' has under its head a reacting spring K² which resting upon the
head K of the screw guide flanged piece k holds the sliding head K with a
frictional bearing up to the screw flanged piece k. The tool head Ko is adjusted
vertically by turning the flanged screw quill piece Kk (see Figure 3) to the right
or left; when in the right place the screw quill flanged piece is held firmly by the
check uut k'.
The tool for trecing the end of the toe of the shoe is shown in Figures 6 and 7,
and consists of a forked piece M, having arms Me pivoted to the tool holder head K
as shown at M, Figure 6 and is held adjustably in place by the screw pin M³ and the
spring M. To one branch of the fork we attach by means of screws m m one end
of a strong but yielding strap M² M' the other end M' of which passes partly
around a friction wheel M³ and is connected to a vertical spring M* the end of the
spring M being connected to the fork M by a screw M³. The central part of the
strap M¹ M³ is connected by a loop M to a spring M" which acts as a counter
to the spring M* and thus keeps the strap M¹ M' always in place and ready for
action.
The working of the strap M¹ M³ on the toc of the shoe is in part the same as the
working of the strap T' (see Figure 1^) on the heel of the sboe, that is as the tool
moves downward the end M' of the strap is held and the end M² yields, thus the
strap is drawn with a rubbing action about the toe of the shoe during a portion of
the descent of the tool carrying head thus fitting the toc to the last. Then the
5 strap passes over the front and finishes a portion of it about equal to the length of
the cap of the toe. All of the tools last described attached to the head KⓇ have,

page_text: besides the up and down motion, an oscillating motion about the vertical screw
bolt K¹.
This motion is effected by the following described mechanism (see Figure 6
and 6). The tool head K is provided with a curved recess K10 which receives a
loosely working cylindrical block K. This cylindrical block Kis mounted loosely
on a crank pin K' on the ratchet disc K', so that as the disc K' rotates, the
cylindrical block K' moves up and down a vertical line in the recess K and also
laterally in a curved path about the bolt K', and in its lateral motion it imparts a
corresponding motion to that part of the tool holder K in which it is located.
That is the rotation of the ratchet wheel K' about its axle pin K" in a vertical
plane causes the tool holder K to oscillate in a horizontal plane that gives similar
motion to all of the tools carried thereon.
A rotating motion is given to the ratchet wheel K' by a fixed pawl K¹º (Figure 1)
attached to the standard F, which as the ratchet passes, engages with one of its
teeth and causes it to make a part rotation.
This machine is adapted to be started by a foot lever and clutch device, or if
desired by hand, said foot lever only acting on the clutch device when a shoe is in
position for being treed, and is provided with an automatic stopping device which
stops the machine as soon as it has caused all of the treeing tools to do the work
required of them in treeing one shoe. The above device may be described as
follows: P (Figure 2) is a foot lever attached to a rocker shaft P₁, said rocker
shaft acting through the crank arm P³ gives motion to the vertical rod P3 P4 and a
guide Pe having a collar Po attached, which acts under certain conditions, to be
hereafter explained, upon the lever N' and through the said lever rocker shaft N1,
arm N and pawl N' (attached by the pin N and held in position by the spring N
upon the ratchet wheel N'.
The guide Pe slides up and down in the guideway P² Ps its downward motion
being limited by the pin P. The part P P is made fast by a key pin P¹³ to the
rod P" which slides in the fixed housing P10, this rod P" has attached to its inner
end by a set screw P¹³ an arm P13; said arm Pis having a heel piece P", this heel
piece is operated upon by the heel of the shoe (see Figure 3) that is, when the shoe
is placed in position for being treed, the heel face will push back the arm P's and
acting through it in combination with the rod P piece P' P will force back the
upper end of the rod P, thus bringing the collar P' (Figures 3 and 9) under the
pin N¹ on the lever N', so that if the foot treadle P (already described) is depressed
it acting on the rod P' through the pin N16, will lift the pawl lever N° from which
motion is transmitted to the pawl Nis, as already set forth.
To clearly understand the operations of the starting and stopping device it must
be remembered that the machine in stopping always leaves all of the parts, indicated
in Figures 8, 9 and 10, in the precise position therein shown, and that none of the
parts are in motion except the gear wheels F F these run loosely on their
respective crank shafts Hand K (see also Figures 3 and 4). The shaft H has
upon it a clutch and cam drum F F which is free to slide but not to turn on the
said shaft, it being connected by splines hh so that if it is made to turn it will cause
its shaft to turn also. The drum F F is held back against the action of springs
indicated by dotted lines at F1 (Figure 8) by the holding pin F10, which rubs
against the face of the peripherally projecting cam F' but when the pin F10 is
withdrawn then the springs Fi will force the cams forward on the shaft so that the
face projection F1 will engage with the corresponding face projection F' on the
gear wheel F' and receiving the motion of the said gear wheel will transmit it to
the crank shaft Hand thence through the intermediate mechanism already described
to the lower set of treeing tools.
The cam clutch device N* N* mounted upon the shaft K is in all respects like the
cam clutch drum F F and is mounted on the shaft K by splines n n and when
thrown forward by the springs n n its face projection N³ will engage with the 5
corresponding projection. on the gear wheel F and be set in motion, the said motion

page_text: being transmitted through the shaft K and mechanism already described to the
upper set of treeing tools.
The automatic operation of the parts is as follows :-Lifting the pawl N" by the
foot lever P, will cause the ratchet wheel N to move in the direction of the arrow,
this movement will carry the block N upon which the block N (on the lever N')
rests, out from the said block and thus allow it and the outer end of the lever N' to
drop, the inner end rising; which action will in turn allow the pin F to be thrown
upward by the action of the spring F thus clearing the face of the cam F on the
cam clutch drum F F and leaving said drum free to be pushed forward by the
springs F so as to engage the clutch projection and be set in motion as described
and to impart its motion to the crank shaft H. The motion of the drum F F® in
the direction of the arrow carries the peripheral cam projection F out from under
the pin F and allows it to be withdrawn by its springs out of the way of the face of the
cam N thus allowing the cam drum N'N' to be forced forward by the springs n° n³
so that it will make a cluch connection with the gear wheel F and partaking of its
motion cause the crank shaft K to rotate.
The parts will continue to rotate and at each rotation to cause all of the treeing
tools to make a full up and down stroke. This rotation will continue until the
projection F on the drum F F' has made as many rotations less one, as there are
teeth on the ratchet N³, that is, at each rotation of the drum the projection F" will
engage with one of the teeth on the ratchet and thus start the ratchet one tooth
ahead. This motion of the ratchet will continue until the block N' comes in contact
with the block N' on the lever N' then the lifting of the outer end of the lever N'
will cause the inner end to force the pin F down by which the wedge-like action
against the face of the cam F° forces the drum F F back on the shaft Hout of.
clutch connection with the gear wheel F; at about the same time that this happens
the cam F comes in contact with the lower end of the pin F" and forces it upward
so as to come in contact with the cam N' on the drum N* N* and thus throw the
drum out of clutch connection with the gear wheel F thus terminating the action
of all of the treeing toole. The treeing tools will now remain out of action and out of
the way of the operator until he has placed another shoe in position to be operated
upon by the treeing tools and he depresses the foot lever P.
Heretofore it has been impracticable to complete the treeing of a boot or shoe by
consecutive continuous operations, for the reason that a shoe in proper temper for
5 some of the work of treeing is altogether too wet for the finishing operation there-
fore it has been necessary to take the shoe off from the machine when but partly
treed and to allow it to dry before the process could be completed. To obviate
this objection I have incorporated with other parts of my machine a device by
which powerful drying blasts of air co-operate with the frictional parts of the
machine to assist in the treeing operations and thus render the process of treeing
continuous and practically automatic. I will now describe the mechanism by which
the result is obtained, reference being had to Figures 2 and 2ª.
For a blast generator an ordinary fan blower W may be used from which a
pipe W W takes the air to the distributing pipes W W W W W'. These
5 distributing pipes are arranged substantially as shown in Figure 2 so as to deliver
to all parts of the shoe powerful blasts of air, and as the several currents of air
collide, a whirl of air in rapid motion is playing around every part of the shoe, thus
drying it so quickly as to complete the process of drying the shoe upon one arm of
the turret, in the same time that the rubbing process is completed upon a shoe upon
O another arm of the turret. Thus by the incorporation of the above described
drying apparatus or its equivalent, in a treeing machine, I am enabled to make the
process of treeing, by machinery continuous and practically automatic. This blast
mechanism requires several times more power to operate than does the rubbing
mechanism.
3 For treeing shoes in which the forward parts of the quarters (counters) are not
wholly united to the vamps, such as brogans, plough shoes, etc. etc. there are attach-
ments fitted to operate with the tree and spread and hold the forward parts open so

page_text: that while said sides are being treed an additional set of rubbing tools properly
operated will pass in between said sides and operate upon the tongue or centre-piece
of the shoe. These parts are illustrated in Figures 11, 12, 13 and 14. The tree
attachment cousists of two flat metal plates J J¹ secured to the sides of the tree C
so that they can be moved under the sides of the shoe after the tree has been spread.
These two plates are connected with each other and when in position are there held
by the spring catch J* which engages with a ratchet formed upon the tree under the
plate J. For the toe portion of the foot the same vertically reciprocating tools are
used as for other classes of shoes.
For treeing the portion of the shoe between the plates J and J' mechanism shown
in Figures 11 and 12 is used consisting of a set of intermittently revolving tools so
timed that they do not collide with the vertically reciprocating tools.
These tools are mounted in proper bearings formed at the outer end of the upper
branch w of the arm w, the arin w being secured to the upper end of the post 13 by
the connection w'. The lower branch of the arm w, 102 is curved down and acts as
a brace to support the tree C against the action of the lower rubbing tools, which
action is considerably stronger than when the tools are used for fine leather, and
there are also more tools.
To give the desired motion to the central operating tools, a rocker shaft w* is
mounted in a proper bearing on the branch w³.
The
Fixed to one end of this shaft is the arm w and the segmental gear w7, the outer
end of the arm w is connected with the crank K' by the connecting rod w.
revolution of the crank K¹ operates the rock shaft w' and the parts secured thereto.
The segment w meshes with and reciprocates the gear wheel w mounted loosely
upon the tool carrying shaft w12.
An intermittent rotary motion always in one direction is given to the tool shaft w¹s
by mechanism as follows:-" is a disc attached to the shaft w by a set screw as
shown or otherwise; this disc woll has a quill projection to in which a pin w₁e is
arranged to slide in and out, it being held normally out by a spring behind it the
outer end of the pin w¹ is bevelled off as shown so that when either of the studs w° w
on the gear come in contact with it from the back side, the pin we will slide into
the quill and the shaft to remain stationary, but at the return motion of the gear
wheels w one of the studs w 1010 will come in contact with the unbevelled side of
the pin and turn the tool shaft.
-The studs are alternately operative. The shaft to¹ is prevented from moving
except when acted upon, as above by the spring brake w¼, the tool shaft w¹³ is made
to move back and forth longitudinally so that the tools will cover all parts of the
centre of the shoe, by means of an endless screw cam ws which engages with a switch
piece to which is swivelled in the block w" and adapted to operate in connection
with the endless screw cam w¹³, in the usual manner. The tools proper w" ware
severally hung on pivots ww20 attached to the arm piece w¹8 on the shaft w; each
of these tools has a yielding bearing on a spring like the one indicated by dotted
lines at . The action of these tools is as follows:-At each revolution of the
shaft the rubbers at the ends of the tools ww come in contact with the vamp of
the shoe and pass over that portion which they are intended to work upon with a
firm but yielding rubbing motion; sufficient repetitions of which motions will suffice
to tree that part of a shoe with which they come in contact. The tool faces used for
treeing the lower parts of brogans are similar to those used for treeing the lower
parts of an ordinary shoe, but the operation of said tools with the exception of the
one operating at the rand line is quite different; the peculiarities of the brogan tools 5
are shown in Figures 11 and 14.
As herein before described the sides of the brogans are spread apart by the
plates J and J which plates tend to incline outward from the centre of the tree and
also extend above the upper end of the largest side of a shoe that may be placed
upon the tree.
Upon these plates the sides of the shoe rest and are submitted to the action of the
rubbing tools which move up and rub to the extreme upper limit of the sides of the

page_text: 0
largest shoe and then the pressure of the tools is removed until said tools have
moved so far down below the edge of the sides that there will be no danger of their
downward motion drawing down and rumpling the sides of the shoe when the tools
again press against the surface of the shoe and operate upon it until the motion of
the tool carrying head carries them below the back of the shoe.
The operation just described is accomplished by the following mechanism which
operates all of the side rubbing tools except the pair working near the rand line of
the shoe whose range of feed does not carry them so that they will act upon the
loose part of the sides.
The standards J carrying these tools (of which there may be any desired number)
are adjustably mounted, and are connected to the sliding tool holder T by the pivot
pins, but instead of having the spring t common to each opposing pair of tools,
each individual tool carrier is provided with the spring J" carried in a pocket in its
lower end and this spring acts through a sliding pin J, (fitted to the outer end of
the spring pocket) against a cam Jo and presses the rubbing tools against the
surface of the sides at the desired times.
The cain J10 is carried upon the sliding bracket J' which moves in the same slide-
way as the brogan tool carrying bracket J" but moves at a different speed and length
of stroke, so that there is a differential motion between the two sliding brackets J
and J. This motion causes the cam J10 to move down past the ends of the sliding
pins J when the tools are ascending towards the upper part of the side of the shoe
and by the time the tools pass over the upper edge the cam has separated from the
ends of the sliding pins J¹ so that they can swing together, and of course, allow
the tool faces carried by the standards J2 to swing clear of the edges of the side of
the shoe. The cam J10 does not touch the ends of the pins J" until the tool faces
have been carried down the desired distance below the edge of the side, when the
tool faces are again brought into contact with the surface of the leather, and the
rubbing is continued down to the point where the tools leave the same.
To operate the sliding bracket J there are fixed outside of the cranks H' other
arms J which are provided with crank pins that are connected to the sliding
bracket J by the rods J' and cross arm J. The crank pins are set at the proper-
angle and radius with reference to those of the cranks H to give the desired
motions.
The cam Jo is long enough to operate sufficient tools for the highest leg shoe
that may be made, and its form is such that as the tool faces move up and down
over the irregular surfaces of the shoes the tension of the springs J1 is not materially
varied.
The use of the plates J and J' in combination with a shoe tree for the treeing of
brogans is novel and the shoes are delivered from the machine in better form for
packing than is the case in the usual method of rubbing the sides on the roundest
sides of the foot of the tree and then straightening them out in the act of passing
them in cases for the market. The use of these plates also permits the simultaneous
treeing of the sides and central tongue of the shoe by the lower reciprocating rubbing
tools and the upper intermittent revolving tools.
The advantage of the arrangement of the side rubbing tools and cam J10 is this,
when the cam is removed from contact from the ends of the pins J the labour of
the machine is reduced instead of being increased as it would be if the rubbing tools
were drawn from the surface of the leather against the tension of springs holding
the tools to their work.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondent, I declare that what I claim is:-
First. In a treeing machine the combination of a swivelling turret head having

Fifth. In a treeing machine the combination of the heel treeing tool consisting of
the rigid standards to mounted upon the vertically reciprocating and horizontally
sliding tool holder T, a sliding rubbing belt T', provided with rubbing tools if
desired one end of said belt being fixed to the top of the standard and the other
end to the yielding quill t, which slides on the standard & substantially as described
and for the purpose set forth when the tool holder T is reciprocated.
Sixth. In combination with a treeing machine the toe treeing or finishing
strap M² M² and means substantially as described to cause it to first form and finish
the end and then the top of the toe of an upper presented upon a tree to its action,
substantially as described.
Seventh. In a treeing machine the combination of the toe treeing tool M, tool
head K screw pivot bolt K on which the tool head is adapted to swivel and
mechanism for swivelling the same as described, and for the purpose set forth.
Eighth. In a treeing machine provided with suitable treeing mechanism the
combination of foot lever mechanism substantially as described connected to the
foot piece P and suitable connecting mechanism to the heel piece P whereby
the presence of a shoe is required upon the tree before the machine can be set in
motion by depressing the foot piece P, substantially as shown and described.
Ninth. In a treeing machine the combination of the tree C, with the plates J, J'
and means for holding said plates in any desired position, said plates being adapted
to support the parts of the sides that the tools are to work on, substantially as and
for the purposes set forth.
Tenth. In a treeing machine the combination of the intermittently rotating and
endways reciprocating shaft w¹, with the treeing tools w", all operating substantially
as described and for the purposes set forth.
Eleventh. In a treeing machine the combination of the sliding bracket J" provided 4

adjusting devices and the automatically adjusting and controlling form J¹ sub-
stantially as and for the purposes set forth.
Twelfth. In a treeing machine the combination of an apparatus for delivering
upon the partly treed shoe a blast of air having sufficient drying capacity to reduce 4
the shoe to the proper temper for completion in the time required so that the
automatic action of the machine may continue at its regular speed and deliver the
shoe without delay for final treatment, substantially as and for the purpose set
forth.

Fourteenth. In a treeing machine the vamp line tools Ts Ts and means substantially
as described for giving them adjustable angular motion, substantially as described 5
and for the purpose set forth.
Fifteenth. The herein described improvement in the art of machine boot and.

page_text: shoe treeing, which consists in first submitting an upper to a thorough rubbing, and
then drying it by a cold air blast of great power or velocity applied externally, so
that an upper will be dried in the time required to rub the succeeding upper
substantially as described and for the purpose set forth.
Sixteenth. In a shoe treeing machine, a turret carrying a series of trees or lasts
for holding shoes, mechanism for revolving the trees to bring them consecutively to
the rubbing and blast mechanisms, and automatic rubbing mechanism in combination
with mechanism substantially as described for delivering a blast of cold air on all
sides of the shoe, whereby a shoe may be first treed and dressed, then rubbed, next
dried and then finished and removed from the tree, these steps being performed
consecutively, substantially as set forth.
