To all whom it'm'ay concern.-

Be it known that I, ABEL D. TYLER, Jr., a citizen of the-United States, residingat Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Machines for Ti'eeing Boots or Shoes, ofwhich the following is a specification, reference being bad therein to the accompanying drawings. Figure 1 is a side elevation of'a' treeingmachine embodying my invention. Fig. 2 is a front elevation of the same, showing a boottree in one arm of the boot-tree carrier and also showing another arin of the boot-tree car- I 5 rier without a thereby-supported boot-tree.

Fig. 3 is a top plan view of the machine, showing a back plan of one boot-tree. Fig. 4. isa

the frame of themachine being shown'in ele- 2o vation. In Fig. 4 the back piece of the boottree is shown closed. Fig. 5 is a lengthwise sectional view of the boot-tree on a line c'orresponding to line 4 4 of Fig. 3, the tree-foot being shown inlocked position and the back piece being shown as distendedthat is, moved rearwardly from the central portion of the boot-tree. This view also shows a lengthwise sectional view of the arm of the tree-carrier and a vertical sectional view of 0 a bell-crank lever and connected parts which cooperate with the slide mechanism-in thecarrier-arm. Fig. 6 is a rear view of the boot= tree with the back piece detached. Fig. 7 is a sectional view of the boot-tree on line 7 7 5 of Fig. 5. Fig. 8 is an under plan view of the slide mechanism contained in the carrierarm and of the bell-crank lever and mechanism carried thereby, which cooperates with said slide mechanism, said bell-crank lever appearing in-sectionp Fig; 9 is a sectional View of the slide mechanism, as shown, partly in section and partly in elevation, the ratchetand-pawl mechanisinthat operates with the slide mechanism, the outer end of the slide- 5 bar forming a part of the slide mechanism being shown in arecess in the middle portion of the ratchet-wheel. Fig-.- 10 is a sectional detail showing the slide-bar which forms part of the slide mechanism contained in the carrier-arm in contact with the solid portion of the ratchet-wheel. Fig. 11 is a which receives the guide-fin a flprojecting .thereinto from. the outer part of the rib a The upper end wall ofthehook-slot a is perspective view of the ratchet-wheel which forms part of the actuating mechanism for the slide mechanism contained in the carrier- -rod. Fig. 12 is a perspective view of the back piece of the boot-tree, and Fig. 13 is an enlarged sectional detail of the catch and hook-shaped rib which'project from the treefoot recess of the tree-leg. This view also shows the method of mounting said rib in the tree-leg and the guideways of the reciprocating tree-leg rod. Fig. 14 is an enlargement at line 14. 14. of Fig. 4, showing the back-piece tang in connection with the grooved projec-' tion from the rear side of the tree-leg- Fig. 15 is-a perspective view of the rear end of the tree-foot.

' In the drawings illustrating the principle of myinvention and the best mode now known to me ofapplying that principle, A is the tree-foot; A, the tree-leg; A, the back piece of mynew boot or'shoe tree, wherein the front or shinedgeof the tree-leg is indicated by a and the tree-foot socket by a. The tree-foot socket a, (see Fig. 13) is at the lower front 7 part of the tree-leg, which is made with a rib a projecting from the front face of the longitudinally-extending wall a of the socket. The transverse Wall a of the socket is pro vided with an opening into the chamber a of 8o the tree-leg. The rib a is provided with-a vhook a the point of which extends toward the inneror upper end of the tree-leg. Within the chamber a of the tree-leg a catch a having a hook end a is pivoted at a the hook end at? extending toward'the point of the hook a The inner surface of the catch a is provided with a lengthwise groove a made concave at 01. and the hook end a of the catch a is caused to move inwardly into oppositionto the concave wall at 01, by'means of the cam-surface a on the'lengthwise-re- 5 i ciprocating back-piece distender. a, the cam surface a engaging the inner or tail end of the pivoted catch a' when the'distender a is drawn inwardly toward the upper end of the boot-tree, as hereinafter described. The lengthwise-reciprocating distenclero (see Fig. 6) moves in the lengthwiseslot a the slot being formed in the rear wall a" of the leg-piece. The back-piece distender a (see Fig. 5) is provided with a rearwardly-projecting arm e preferably carrying an antifriction-roll a, which engages with the cam-surface e of a recess on the inner side of the back piece A which is movably mounted between the side wings a of the leg-piece and is held in operative position by means of the slotted tang a, which engages the rearwardlyprojecting stud a fast on the rear side of leg-piece A at a distance from the upper or inner end of the back piece A and also by means of a spring a, one end of which is made fast to the inner or upper portion of the tree-leg A and has its free end extending toward the heel of the back piece and engaging the upper rear wall thereof to hold the back piece normally against the rear wall of the leg-piece under tension. The tension of spring a is regulated by any suitable tension device, which is made up in this instance of a screw 06 integral with the stud ta and the outer nut of, the inner nuts (1 and a limiting the movement of the tang a. It is frequently necessary to change the back pieces when, as in Fig. 4, the inner nuts are screwed up so that the nut (L27 bears against the inner side of the spring. The nuts e and a may be adjusted on the screw into different positions. If, as in Fig. 1, the nut a be left out and the nut e be screwed down to the stud (r nut a will turn in the movement tang (1 and a convenient way of making the back pieces readily detachable from the treeleg is to form the slotted tang a with an orifice, which is a loose fit for stud e as inFig. 14, said orifice being open on its inner side and provided with opposed inward projections a a, one on each side of said orifice, and to form the sides of said stud (L23 on each side with an upwardly-inclined groove a, as in Fig. 5, of a size to receive and permit the passage of the inward projections a. The

tang (1 projects upwardly and outwardly beyond the end wall of the back piece A and by passing the upper or inner end of the back piece under the free end of the spring 01 so that the projections a will enter the slots a and then forcing the back piece inwardly the projections LL29 will pass through the slots a past the upper wall a of the stud (1 so as to engage said wall below the upper ends of the grooves a when the tension of the spring a forces the back piece A toward the legpiece A. The back-piece distendera moves the back piece rearwardly against the tension of said spring a, which not only helps to secure the back piece on the tree-leg, but, what is more important, gives a resiliency to the operation of the machine that tends to prevent undue stretching of the leather at the heel portion of the shoe. The direction of the grooves e is upwardly and rearwardly in relation to the tree-leg. The outer wall of the grooves a is cut off at e in order to permit the ready insertion of the projections a into the grooves a The wall it, inwardly of the with a lengthwiseextending rod upon.

which a coiled spring (L is mounted, one end of the spring a abutting against the shoulder a of the distender, while the inner end of the spring abuts against the inner end wall a of thetree-leg, this wall being perforated for passage therethrough of the rod 61, the inner end of which is rotatably secured in a swivel-loop (r for attachment to the stud of the reciprocating stretcher-plate, hereinafter described. The distender is drawn back against the tension of spring 0.3 so that the operator by a sense of feeling soon learns to feel or know when a prudent degree of strain is brought on the leather, and as the distending operation is a straining operation on the shoe the resiliency which the spring (1, imparts to the operation of the apparatus when the back piece is moved rearwardly greatly assists the operator in guarding against undue stretching of the leather.

The rear Wall of the tree-foot A (see Fig. 15) has a vertical groove (1 of a width and depth sufficient to form a sliding fit with the rib a and the catch of, already described. A transverse pin a through the side walls of the groove e is provided for the tree-foot. The tree-foot (see Figs. 4 and 14) is attached to the tree-leg by passing the groove a over the rib a with the transverse pin or catch member a located between the upper or in ner end of the hook at and the lower opposed end of the catch a and by then moving the rear wall of the tree-foot against the inner lengthwise wall a of the tree-leg and then sliding the tree-foot inwardly, so that its upper rear wall a engages the transverse wall a of the tree-leg. When in this the higher position of the tree-foot, the catch member d of the tree-foot engages the concave surface at a, and by moving the distendera, inwardly-that is, toward the hub I)? of the carrier--the cam-surface a thereof engages the inner or tail end of the pivoted catch a and forces the hook end a thereof over the pin a so that the pin a is inclosed by the surface a and the hook end a of the pivoted catch and the rear and upper walls of the tree-foot locked firmly against the corresponding walls a and a of the tree-leg. The function of the hook at is to engage the pin a of the tree-foot when the latter is in its lower position, as in Fig. 16. The inner movement of the distender a, provided with this cam-surface a, which is instrumental in looking the tree-foot in position, also carries the antifriction-roll a against theheelward and outward incline of cam surface a of the back piece, and consequently distends (to a greater or less extent) the back piece with relation to the tree-leg and tree-foot, and itwill be observed that when the back piece is thus distended (or moved away from the tree leg) theback piece is in reality f ulcru mod on the antifri'ction-roll a, the play of the inner end of tang 0. of the back piece being limited by adjustment of'the inner nuta if so de- Theforegoing is a description of my new boot-tree whereof the described locking mechanism for securing the tree-foot to the treeleg is one ofmany forms'of locking mechanismswhich may be used for the purpose, if

so desired. boot-tree thus described consists in looking the front wall a of the tree-foot socket and the rear Wall or surface of'the tree-foot back ofthe shank of the'tree-foot, sojthat' the end extension a ,having a circumferential groove a and shoulder 0 The extension 0, is made to fit in the recess in one of the arms b.

of-the tree-carrier B, the shoulder a abutting against the end surface of the arm of the carrier and the circumferential groove a in the extension receiving the inner end of the screw b, so that the tree as a whole is'mount-- ed rotatably on its longitudinal axis in its carrier. The construction above described willbe best understood by reference to Figs.

1, 5, and 6.

The tree-carrier B, forming part of my present apparatus, is preferably provided with a plurality of horizontal arms b, two arms be-.

ing shown in this case, as in Fig. 3, although any desired greater number may be provided. The carrier B comprises'a hub 6 from which the arms I) radially project. The arms 21, with their contained mechanism, are similar, anda description of one arm and its contained mechanism will sufficefor-all. The arm I) is lengthwise chambered to receive within its outer end the extension (1 of the tree-leg, as

above mentioned. Between the side walls of the'chambered arm I) there is mounted a re ciprocatin g slide b conveniently formed with side ribs 17', Fig. 8, which fit in guide-grooves 19 Fig. 4, in opposite walls of the arm-chamber b. A stud 19 projects from the slide b and it is on this stud b that the swivel-loop a 'flabove referred to, is hooked for-the pur pose of retracting the backrpiece distender a, which also is instrumental in looking the tree-footin position. The slide b is also provided with an abutment b against which the spring b impinges. In this instance the spring 19* is a coiled spring, one end of which is made fast to one side wall of the arm-chamber b ,while the other' end of the spring is made fast to the other side wall of the-armchamber I), (see Fig. 3,) each point of attach ment of the spring to the side walls of the An important feature of the,

arm-chamber 19"" being forward of the abutment and the spring being under sufficient tension on the abutment b to keep the slide at the forward end of its grooved ways b where it is arrested by any convenient stop, such asb -When the slide b is in its most forward position, the therewith combined rod 0. which projects from the back-piece dis:

tender, is in its most forward position,as shown in Fig. 4, (by most forward position in this connectionI mean the position nearest the foot of the tree,) and in this position theanti-l friction-roller a and the cam surface or incline a are respectivelyout of engagement with the cam-surface a of the back piece A and the catch a", the tree-foot being then in position to be locked to the tree-leg and the back piece being closed up against the treeing placed upon the tree-foot when the tree- 85 7 leg. In this position of the parts or when the foot'is inits lowest position. When the trees 7 foot is in its lowest position, the transverse,

pin a is in the hook-slot 0. and to efiect the lockin g of 'thetree-foot in its highest position and the distension of the back piece the slide b connected to the swivehloop a of the boottree above described, is moved inwardly to ward the'hub of the carrier against the tension of the spring 12 and against the tension of. the spring a. The-cam-surface 01/ the tail end of the catch a. slightly before the antifrictionroll0t engages the camsurface of the back piece, and this is done in order that by a slight movement inwardly of the'slide b the tree-foot may be locked in itshighest position. The movement away from the tree-leg or distention of the heel portion of the back piece requires to be regulated to suit the work in hand, and I consequently provide the slide 71 with a mechan ism which effects a locking of the slide at any desired point of its inward movement. This mechanism preferably comprises the rack: plate o fast on the arm b, between the teeth of which the pawl 19 (see Figs. 4 and 8) en gages step by step as the slide b is moved inwardly to pull the rod 0. and its attached parts away from the leg-piece. When the slide 5 is pushed inwardly and the push which carries it inwardly ceases, the pawl 19 engages a tooth of the rack-plate Z9 and the slide b is arrested and locked in the position whereat therearward push on the slide ceased, the pawl being held in cooperating relation with spring 13 one end of which is made fast to the pawl and the other of which is made fast to the slide. To release it from its locking engagement with the rack, I provide the Slide 19 with a pin b and a lengthwise groove, in which is'mounted a bar I), that slides .'endwise of said groove, andconsequently in the direction of the path of the slide 11 The is preferably so prolonged that it engages 5 the teeth of: the rack-plate by means of the pawl b is pivoted on said bar I) by means of the pawl-pivot Z9 andthe slide-bar (Z is held normally forward, so as to cooperate with the spring I) in holding the pawl in looking engagement with the rack-plate by means of the spring b, one end of which is fast to the slide-bar Z1 and the other end-of which is fast to the slide 11 substantially, although specifically to the forward one of the two crossbars I)", which are made fast to the slide 19 and keep the slide-bar Z1 in the groove in the slide 19 It will be evident that if an inward push is exerted upon the outward end of the slide-bar b the slide-bar will be carried inwardly in the slide 1) and the pawl I), by co ming in contact with pin 12*,- swung out of engagement with rack, the butt-end of the pawl thus being carried inwardly of the position in which it must be in order to maintain its looking engagement with the rack-plate,and thereby leave the front end of the pawl I) out of locking engagement with the rack-plate. When the slide-bar is in said inward position,

the slide 19 may move outward under the ten-' sion of its spring b and the expansion of the spring a will cause the boot-tree rod n to move outward with its attached parts.

For actuating the slide b and its contained slide-bar I) (see Figs. 1, 5, 8, and 9) I provide the bell-crank lever D, one end of which is attached to the treadle-rod d and the other end D of which projects upwardly into the arm-chamber D The lever D is fulcrumed conveniently in a yoke D secured to frame F Journal D, on which the hub 19 of the boot-tree carrier B is rotatably mounted, is formed on a standard, also secured to frame F. The upper arm D of the lever D is forked and provided with a rotatable ratchet-wheel d, the circumferential middle portion d whereof is made withoutteeth and with recesses (l The peripheral margins of the ratchet-wheel d are toothed at (1. The ratchetwheel 61 is rotated by the lengthwise-reciprocating pawl d which is mounted upon a rod cl, endwise movable in lugs d projecting from the outward side of the upwardly-projecting lever-arm D. The pawl d is pivoted to the upper end of the rod d and forced inwardly to engage the teeth of the ratchet-wheel d by means of the spring 01*, the rod (i which carries the pawl d reciprocating, Fig. 5, and being moved upwardly in its supporting-lugs (1 when the lever-arm D is swung outwardly by the engagement of its lower end (preferably provided with a cam-roll d with the cam,- surface c1 conveniently formedon the frame D The upward rectilinear movement of the pawl-carrying rod d pushes the pawl (1 which is in engagement with the teeth of the ratchet-wheel, upwardly, so as to rotate the ratchet-wheel step by step or tooth by tooth. \Vhen the treadle D, connected to the treadlerod (Z, is lip-that is, when the upwardly-projecting arm D of the lever D is in its outer position--the pawl cl is in inoperative position with relation to the ratchet-wheel d, and when on every second depression of treadle-rod cl one of the recesses d in the middle portion d thereof is by pawl d brought opposite and in position to receive the pin Z1 which is the outward rigid projection of the slide-bar I), above described, the treadle-rod cl carries the lever-arm D inward, the pin being received in said recess (1 (See Fig. 9.) The consequence is that the contact of the lever D and the therein-contained ratchet-wheel with the front end of the slide 12 moves the slide b inwardly against the tension of its spring the desired distance according to the depression of the treadle, so that the tree-rod LL and its connected parts are pulled inwardly to lock the tree-foot and to distend the back piece, as already described, the pawl 11 cooperating with the rack-plate b to lock the slide in the desired position. Removal of the foot from the treadle D or of the pull on the lower arm of the lever D permits the lever-arm D to move away from the outer end of the slide 19 spring (1 being conveniently provided for this purpose and connecting the treadle with the frame of the machine or otherwise. By the movement of the upper end of the leverarm D toward the opposed end of the slide b the end of the rod d is carried out of engagement with the cam-surface 01 and the coiled spring 01 on the rod (1 having for its necessary abutments the under surface of the upper lug d and a shoulder d on rod (1 forces the pawl carrying rod (Z downwardly, and thereby carries the pawl 61 downwardly over ratchet-wheel cl into position for engagement with tooth d thereof. The ratchet-teeth d and holes (1 are so disposed in relation to the other that when the leverarm D is moved toward the slide?) the next time after the forward movement which has left the slide in-locked position an imperforate part of the center portion (Z of the ratchet-wheel is brought against the pin 12 so that the slide-bar Z2 is moved inwardly toward the hub of the machine and the pawl 13 moved against pin b on slide b and out of locking engagement with rack-plate. If the foot be now taken from the treadle D, the slide 11 and the ratchet-carrying end of the lever-arm D,will move together toward the treeleg to release the tree-rod (L33 and its connected parts. The construction of the ratchet-wheel d by which I secure the stated cooperation of the ratchet-wheel with the slide-bar b consists in providing the middle portion (1 of the ratchet-wheel with an imperforate part opposite every other of the marginal ratchetteeth with which the wheel is provided, so that a hole (1 and an imperforate part of the middle portion (1 are alternately presented to the projecting pin Z2 of the slide-bar b As above stated, the hub of the carrier is preferably rotatably mounted on the journal D and provided with a plurality of tree-carrying arms Z), and where the tree-carrier is' provided with more than one arm it is practically desirable that the carrier be rotary on the journal D on the standard on frame F 1 consequently pr'ovidethe frame and carrier with a mechanism for locking the carrier in such position that the lever-arm D, with its contained mechanisms,may cooperate with v one of the desired carrier-arms b andthe parts supported thereby. A great variety .of, such locking mechanisms may be. contrived; of course, withoutdeparture from my in- .vention; but thatwhich I have now incorvporated (see Fig.'et)'consists of a recess) in t the under wall of the hub b jand a spring-f controlled rod F, pivoted to the locking-1e verf, which isful-crumed to, the frame. of

When the treadle F is 'depressed, the lever f is pulled down, and ther'od F is thereby pulled out of engagement with the recess f against the tension of its spring f huh 1) maybe now rotated on the supportingjournal D and whenanother recess f, with which the hub isprovided, is brought over the endjof the locking-bar]? (the operators foot being removed fromthe treadle) the spring will cause the bar to project into the recess f. The recess f corresponds to an arm .1), so'that when a recess f is in engagement with the bar]? one of thearms b will be in operative position with relation to the lever-' arm D andthe parts carried thereby. In the present machine, in-which two arms are shown, each of the inner walls of the-arms is cut away, as at f, .(seeFig. 2,) so that the arms may be swung over the upwardly-projecting end of. the lever-arm D. The hub b and its standard (see Fig. 1) are provided with cooperating abntments whicharrest the swing ofthecarrierwhen it is moved to bringone of the other arms intoworking position withthe lever-armD' and connected parts. These cooperating abutments are conveniently formed by the two shonldersf f on the standard, between which the downwardly-projecting pin f onthehub 19 plays. In my new treeing-machine the back piece I is automatically secured in its distended polsition substantially assoon' as the operator perceives that the rearward motion of the back p-iece'has pulled the toe portion of the shoes properly tight upon the toe portion of There are, of course, various mechanical ways of obtainingthis result; but in the present instance I obtain it by automatically stopping, the, outwardqmovement' of the distendin -rod a and the swivel (1 01 equivalent connection, which is secured to the stub b of the reciprocating slide b when i in their inward positions.

The foregoing now preferred embodiment of my invention containsa feature of my'in- Vention which is of great importance. It will be seen from the drawings that the bottom end portion of the web a of the treefleg is 1 .much thinner-than usual, that the front wall .of said web a inclines" upwardly-and forwardly toward the transverse wall a of the tree-leg, that the angle formed by. the front wall of web at andthetransverse wall a isan obtuse angle, and that therear edge of the heelportion of back piece a and the rearend .ofthe foot-pieceA(when thelatter is assembled with'tree-leg and in its higherposition, v as'shown' in Fig.1, for example) are approxi-j i mately parallel, in consequence of which practical or approximate'parallelism it is pose sible to lower the tree-foot into its lowest position withoutany lengthening, as heretofore,

of the shoe-containing parts of the apparatus.

Consequently thereis no binding of the heel.

portion of the back piece in the shoe during the process of removal, and the workmanis able to work faster and without distorting the heel portions of the shoe (or any of its other parts) in pulling off the shoe. This is In consequence of the obtuse angle'ahove mentioned it is possible to have practically all of the shank portion of the apparatu's'a part of the ailtwoodtreefoot, or, in other words, to. give a maximum length, to the tree-foot from its toe to itsrea-r bottom corner, sothat ainaximum portion of the complete foot portion of the apparatus,

taken asa whole, is made up .of the tree-foot,

the bottom of which, together with the outer end of the web, forms a continuous bottom for as much of the tree as is forward of the back piece'when the latter is distended. This insures a better shaping of the shank, portion of the shoe than is practicable where the rear end of the tree-foot is in the shank of the shoe, and the slant of the web a is such that when the tree-foot is pulled down to put on or take off the shoe the distance between the toe and heel of the back piece shortens by nearly a shoe size, thereby preventing binding and distortion and facilitating the work of the operator.

Tree-feet, as heretofore made, have sometimes been provided at their tops with metal plates, as m in my Patent No. 319,355, of 1885, and in other casesavith foot irons, as H in the Mawhinney patent, No. 393,514, the

foot-iron covering the top of the tree-foot and extending downwardly into the vertical groove in the rear face of the tree-foot. These metal fixtures are objectionable because of their expense and liability to work loose and also because the workmen frequently hit the lower front corner of the tree-leg and mar that corner, so that an indentation sometimes appears at the front of the joint formerly the transverse wall of the tree-leg and the top of the tree-foot. Such an imperfection is objectionable, because all surfaces of a tree should be smooth to prevent the formation of imperfections or ridges in the leather of.the shoe. I accordingly prefer to make my tree-foot wholly of wood, excepting only the catch member within the vertical groove in the rear end of thetree-foot.

I have referred to the angle formed by the front face or wall of the tree-leg web at the bottom portion of the tree-leg and the transverse wall as obtuse. form; but if the transverse Wall a were only slightly inclined forwardly and downwardly, so that the said angle would be acute, it is probable that the tree-foot would not be seriously weakened, as it would be were said angle very acute, so that the upper rear corner part of the tree-foot would bea sharp-cornered projection. Such a construction of the tree-foot would greatly weaken it, as will be plain to all skilled in the art. The preferred obtuseness of said angle is obtained by the described slanting of the front wall or surface of said web and by making the transverse wall a at right angles to the lengthwise axis of the tree-leg. It will be observed that the upper rearcorner of the tree-foot presents an,

This is the besttion of the tree as a whole, as will bereadily understood by those familiar with boot and shoe trees wherein the tree-foot is secured to an endwise-movable rib sliding in lengthwise ways in the tree-leg and involving cooperating parts which are dispensed with in my trees.

What I claim is- 1.
