To-all whom 'it may concern:

Be it known that I, WILLIAM II. Hoornn, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in .Treeing-Machines, of whichthe following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to boot and shoe treeing machines, and more particularly to that type of such machines wherein a head or turret carries two kor more trees and is brought into position for the treeing operation by rotative movement of the head or turret.

The aims and generalobjects of the present invention will best be `made clear by the following description and accompanying drawings which disclose one form or em-` bodiment of the invention, it being understood that the characteristic features of the invention in its proper scope are definitely pointed out in the claims. l

In the drawings, Figure 1 is a side elevation of a boot treeing machine embodying the present invention, some of the `parts being broken away to more clearly illustrate the construction of parts beyond; Fig. 1a is a detached detail of Fig.v1; Fig. 2 is a central, longitudinal, vertical section through one of the boot trees with the parts thereof in contracted or non-eXpansible position; Fig. 3 is an end view looking in the direction of the arrow,A Fig. 2, and showing the bottom of the foot-piece, the end ofthe heel and slides, the bottom expansion plate being removed; Fig. 4 is` a section on the line 4 4 of Fig. 2; Fig. 5 is a central longitudinal section similar to that ofFig.` 2, but showing the boot tree in boot or shoe expanding position;` Fig.` 6 is a section on line 6-6 of Fig. 5; Fig. 7` is a detached detail, partly in section, of the upper and tongue engaging device;A Fig. 8 is an end view lof the slide bars, lookingfrom the right in Fig. 5;I `ig.` 9 is a detached detail view of theA lock for holding a boot tree from rotative movement on its axis and for locking the head or turret from rotation when the boot tree is rotated from the position indicated; Fig. 10 is a detailed sectional view on the `line 10-10, Fig. `1; Fig. 11 is a detached perspective view of the treadle or cam block; and Fig. 12 isa detached detail view on an enlarged scale on the line 19.-12, Fig. 1.

The main supporting frame for the machine may be of any usual or desired construction and is shown as comprising an upright column 1 supported upon a flaring or enlarged base 2 and carrymg the operative parts of the machine.

The standard or column 1 is preferably hollow and is provided with ways 3, 4 in which slides the treadle or cam block 5. In order to raise the treadle or cam block 5, the same is connected by a link 6 to a treadle 7 pivoted to a treadle support 8 at the point 9, and provided with a toe 10 to which one end .of a spring 11 is secured, the opposite end of said spring being attached at 12 to the column or main frame 1, whereby the treadle 7 is normally held in its raised position as indicated, and the treadle or cam block 5 is retained in its lowered position.

In order to cushion the downward movement of the treadle or cam block 5, the main frame or standard 1 is provided with suitable guide rods 14, having the adjustable clamps 13, and a sliding cushion bar 15, a

suitable spring 16 being disposed between the clamps 13 and cushion bar 15, and normally acting to hold the bar 15 in raised position to meet the lower surface of the cam block as it descends. i

The treadleor cam block 5, Figs. 1 and 11, preferably comprises three cam` carrying portions 17, 18 and 19, said portions being either formed integral or assembledin integral relation to move in unison. Extending downwardly and toward the front from near the rear portions of the cam carrying parts 1.7 and 19 are the cam grooves or slots 2O and 21, the characteristic shape and direction of` which are such as to impart to the respective levers, the ends of which are engaged thereby, movements as will hereinafter more fully appear. The central cam carrying portion 18 is likewise provided with a cam groove 22 which will be of such shape as to impart to its appropriate lever the desired movement as will hereinafter be more fully pointed out.

appropriate cam slot in the treadle or cam block 5. That is to say, the lower end of each of said levers 24, 25 and 26 has a pin or roller connection with a cam slot in a treadle or cam block 5, whereby, upon upward or downward movement of said cam block, said levers will be appropriately moved about their fulerum 23.

The upper end of each of the levers 24, 25 and.26 is provided with a slot or opening 28, to be engaged at suitable times by downwardly projecting toes or fingers on certain slide rods which serve to expand and contract the tree, as will be presently described.

' Mounted upon a stud 29 projecting from the column 1, Fig. 1, is a rotatable head or turret 30, said turret being preferably held in proper position by means of suitable washers or sleeves 31, 32, disposed on opposite sides thereof, as indicated in Fig. 1. The hub of the turret 30, Fig. 12, has secured thereto or formed integral therewith a turning cam or part 33 having suitable shoulders 34,l one corresponding to each of the boot trees carried by the turret, and said shoulders being adapted for engagementl by a pawl 35, Fig. 12, pivotally mounted at 3G upon a block 37 mounted for vertical movement in suitable ways 38 in the column 1, a spring 39 normally acting to hold the pawl 35 in the position indicated by Fig. 12 so that the end thereof will, upon upward movement of the slide 37, engage one of the shoulders 34, a pin 40 serving to limit the turning movement of the pawl 35 under the action of the spring 39.

Mounted upon the support 8, preferably coincident with the axis 9 of treadle'7, is a treadle 41 having pivotally connected to its inner end at 42 a turret actuator 43, which, in the present form of the invention, is represented as a slide link, the upper end of which is connected at 44, Figs. 1 and 12, with the slide block 37, whereby, upon depression Yof the treadle 41, the said slide block 37 and the turret turning pawl 35 carried thereby will be actuated to turn the turret, the momentum thereof acting, after the turret has been started, to bring one or another of the trees into operative position. The treadle 41 has a toe or projection 45 to which is connected one end of a spring 4G, which tends normally to keep the treadle 41 raised and the treadle actuator 43 in its lowered position.

In order to prevent rotation of the turret in the opposite direction a suitable stop is employed between the turret and the stud or shaft 29, Fig. 12, said stop in the present form of the invention comprising an angular l recess 47 formed in the stud or shaft 29 and containing a stop roller 48, the construction being such that the pawl 35 may rotate the turret freely in the direction of the arrow, as will be clear to those skilled in the art,

but reverse rotation of the turret will be prevented by the roller 43 binding between the stud or shaft 29 and the interior wall of the turret hub.

It is desirable, when the turret has been rotated to bring a boot or shoe tree in position for treating the boot or shoe thereon, that the turret be locked from further rotative movement, and it is likewise desirable that, on actuation of the turret turning means, the turret be unlocked so as to be free for 1novement about its supporting stud or shaft 29. To this end there is mounted upon the main supporting frame or column 1 at 49 a` lock 50 which is normally held in the full line position indicated by Fig. 12 by a spring 51, the end of which is secured to the column at 52 and engages the lock 50 at 53, where by said lock 50 1s normally held resting upon a pin 54 and in position to be engaged by a stud 55 on the turret, one of said studs being disposed on the turret adjacent each of the boot trees, as indicated in Fig. 1.

By reference to Fig. 12 it will be noted 'that the lock 50 has a circular recess 5G, bestshown by dotted lines in said Fig. 12, and that the part 57 of said lock is inclined, whereby, upon rotation of the turret by the means substantially as hereinbefore described, a pin 55 will ride along the incline 57, lift the lock 50 until it arrives opposite the circular recess therein, whereupon the spring 51 will automatically throw thc lock into locking position.

In order that the lock may be automatically freed when the turret actuator is operated to rotate the` turret, said lock 50 has pivoted thereto at 58 a lifting pawl 59 normally acted upon by a spring (50 to maintain the hooked end (S1 of said pawl in engagement with a projection G2 on the slide 37, so that upon raising the slide 37 the lifting pawl 59 will raise the lock 50 out of engagement with the pin o-r lug 55 before the pawl starts the turret by reason of a slight lost motion between the pawl and cooperating shoulder 34.

In order that the lock 50 when thus disengaged from the pin may be returned to its lowered position, as indicated by full lines in Fig. 12, before a pin 55 on the turret arrives in position to be engaged by it, the column 1 is provided with a trip pin (33 which, upon upward movement of the lifting pawl 59, meets the cam surface G4 on said pawl and trips its end G1 from the catch 62, whereby the spring 51 at once returns the lock 50 to its normally locking position, so that, as the turret rotates and the pin 55 is brought into position to be engaged by the lock, said pin will ride along the incline 57, lift the lock 50, and. the spring 51 will return the lock into engagement with the pin 55 when the latter reaches a point opposite the locking recess 5G therein.

From the construction described it will retis unlocked by depression of thetreadle 41, and by the same movement the turret is given itsdesired rotation until the next boot or shoe tree reaches proper position, whereuponthe lock automatically stops and locks the turret.

" the operator."

Having reference more particularly to Figs. 1,12 and 5, it `will benoted that the turret is provided with two, or it may be more, boot or shoe trees, and said turret is suitably formed with bobt tree supporting members 65, each of which forms a bearing for the cylindrical portion 66 of the Lboot tree, said cylindrical portion being provided with a circular recess 67 engaged by the end 68 of a usual retaining" screw/,dotted lines Fig. 5, whereby the boottree may be readily turned in its member 65 bymeans of ahand wheel 69 to bring all parts of the boot or shoe into operative position convenient for """EXtending from thecylindrical portion 66 'of the tree is the leg portion 70"provided with a central slot in which are mounted the slides 71, 72 and 73, each of which is provided with a toeordownwardlyprojecting nger 74 for engagement with the slotted upper ends 28 ot' the several levers 24, 25 and 26 hereinbefore referred to.

Passing through a lug7 5, Fig.` 6, formed as part of the leg oortion is a pin 7 6 surmounted by nut 77 betweenwhich and the head of the lug is the spring 78 normally tending to lift saidpin 7 6. At its lower end the pin carries a toe or rest`7 9 and a finger piece extension 80.

` "The back of the leg portion 81 has secured, at its end remote froml the heel, a plate 82 having a projection 83 formed witha recess orseat 84 adapted to engage the toe or rest 79 carried by the pin 76, the construction being such that upon depression of the `pin 76 the back 81 may be `readily placed in position or removed.

Secured to thebaclr 81`3are the wings 85,4 85, Figs. 3 and 4, the `free ends 0i' whichare adapted to embrace the leg front 70 in the usual manner and, to maintain said wings 85 in close relation with the front of the leg, said wings'85 have a transverse flexible connection 86, preferably formed as a spiral spring, Figs.2, 3 and 5L fAs hereinbefore indicated, eachtree is providedwith three slide bars 71,72 and78, the lower one of which, 73, Figs. 2 and 5,has

`a depending lug 87 to which is secured a pin 88""er`itending` longitudinally of the tree. Said pin 88 passes through a lug or projection 89 of a heel actuator 90 and issurmounted by suitable nuts 91 between which and the lug or projection 89 is interposed the spring 92, whereby, upon movement oi the slide 73 the actuator 90 will be given longitudinal but yielding movement, as will be clear.

` Pivoted to the "central portion of the tree leg at "93 is a lever 94 having one arm connected to the actuator `and carrying apin 95 which travels in a suitable seat or recess 96in the heel portion 97 o'l' the tree, as best shown in Figs. 2 and 5. The construction issuch that upon longitudinal movement of the actuator 90 to the right, the pin 95 will be turned outward and carry with it the heel 97 of the leg back 81, the action being a yielding one by virtue of the spring 92, as hereinbefore indicated.

Disposed above the slide 73 is the slide 72-`which is guided in suitable ways in the tree leg, as indicated, and carries at its front end portion a camlug 98 having its forward edge inclined, as indicated, Afor a purpose that will presently appear.

Surmounting the slide 72 is a `third slide 71which extends into the tree leg and carries at its forward end a support 99, said support being preferably slotted at 100 to receive side extensions 101 of the projection 98 carried by slide 72. The support 99 at its front portion 102 is raised somewhat above the surface of the slide 71 to receive beneath it, and between itself` and the slide 71, a bridge piece 103 secured to the orepart 104 of the last, said last being substantially of the` character of my prior application, Ser. No. 324,314, tiled July 2, 1906.

lFivotally mounted at 105 on the support 99 `is the sole plate carrier 106, the upper end of which is adapted to receive a loop 107 of the sole plate 108, a spring 109 serving to hold the loopin desired position. The end of the carrier 106, regardless of its construction, serves as a support for the sole plate 108, "which, as indicated in Fig. 3, may normally rest infa recess 110 made in the forepart 104 of the lastor foot piece. The end of the support or carrier 106 is preferably provided with separate step portions 111, whereby, in the use of diii'erent size or character of boot tree feet or lasts, and different size and character of sole plates 108,

izo

the lower portion of the support 106 to 1 maintain the plate 1081within the recess 110 of the foot piece, and the lowerend 113 in position to be engaged by the cam` projections 98 of the middle slide bar 7 2.

The foot piece or forepart 104 is provided with the recess 114, Figs. 2, 3 and 5, and has the bridge piece 103 extending trans- `versely of this recess in position to engage v from under the end 102 of the support 99,

and is likewise capable of being put in position, when the parts are disposed as indicated in Fig. 2. In order to hold the foot piece 104 in position on its slide 71, Fig. 2, there is secured to the slide 71 a detainiug finger 115 pivoted at 116 and normally held inV raised position, as indicated in Fig. 2, by a spring 117, the construction being such that when the foot piece forepart 104 is placed upon its slide bar 71 and the bridge piece 103 under the end 102 of the support 99, the end 118 of the detaining inger 115 will engage the crown or top of the foot piece, as indicated, and hold the bridge piece in locking connection with the support 99. In Fig. 2 the parts of the boot tree are shown with the foot piece 104 placed upon its supporting and operating bar 71 and the parts in unexpanded relation whereby a boot or shoe may be readily placed upon the foot piece. YVhen the slide bars 71, 72 and 73 are moved longitudinally, the firstaction is to move the foot piece toward the leg by means of its slide bar 71, and then to move the heel 97 away from the foot piece, and thereafter to move the sole plate 108 directly outward from the sole of the foot piece 104, as indicated in Fig. 5. This expanding movement of the slides 71, 72 and 73 results from a depression of the treadle 7, which raises the treadle or cam block 5 and causes the ends of the levers 24, 25 -and 26 to travel in their cam grooves 20, 21 and 22, moving the upper ends of said levers, at the time in engagement with the projections or toes 74 of the slides, outwardly or to the right.

In order to maintain the levers 24, 25 and 26 in their outward or expanding position, as indicated, the treadle or cam block 5 is provided with a notch 119, Figs. 1 and 11, adapted to be engaged by a catch 120 carried by the lower end of a lever 121 pivoted at 122 to the column 1, the upper end of said lever being provided with a beveled end 123 which is adapted to be engaged by a lug 124 on each of the barrels 65 of the turret or head 30, the construction being such that, when the turret or head 30 is rotated and a tree is brought into upper position to receive a boot or shoe, the said lug 124 will meet the inclined end 123 of the lever 121 and withdraw the catch 120 from the notch 119 of the treadle or cam block 5, thereby permitting said cam block to drop into the posit-ion indicated in Fig. 1, and to move the ends of the levers 24, 25 and 26 inward, as indicated in Fig. 1, ready for the next expanding operation of the boot tree. The lever 121 has its lower end disposed above a flange on the arm 125 of a lever 126 having a foot operating portion 127, so that should it be desirable at any time to drop the treadle or cam block 5 and permit the upper ends of the levers to move to the left, Fig. 1, thereby releasing the parts from the expanded posit-ion, this can be done readily by a foot operation of the lever 126.

In order to maintain a boot tree in expanded position, that is to say, with the slides 71, 72 and 73 in their position, as indicated in Fig. 5, there is provided in cach of the slides 71, 72 and 73 a slot 128, Figs. 2 and 10, which are adapted to be engaged by a locking piece 129 pivoted at 130, Fig. 10, on the rear face of the tree cylinder 66, said locking piece being provided with a slot 131 embracing a guide pin 132 projecting from the face of said cylinder. The toe end 133 of the locking piece 129 rests upon the upper end of a spring actuated pin 134 carried by a suitable support 135 mounted on the face of the tree cylinder, the lower end of said support 135 being formed with a toe 136 adapted to be engaged by the slotted end 137 of a lever arm 138, whereby when the parts are in engagement, as indicated by Fig. 10, the lever arm 138 prevents rotal tive movement of the boot or shoe tree. The arm 138 also carries a pin 139 which engages a slot 140 in the locking piece 129, the construction beinff such that when the arm 138 is depressed from position, as indicated in Fig. 10, the pin 139 will ride down the recess 140 and move the locking piece 129 into engagement with the slots 128 in the slides 71, 72 and 73, and Simultaneously therewith the toe 136 will be released by the slotted end 137 of the arm 138. Thus when the arm 138 is moved from engagement with the locking piece 129 and toe 136, as indi- 110 cated, not only will the slides 71, 72 and 7 3 be locked in, their retracted or expanding position, but the boot tree itself will be free to rotate in its barrel 65.

The arm 138 is carried by a lever 141 piv- 115 oted at 142, Fig. 1, upon the top of the column 1, and has depending therefrom an actuating rod 143, which, near its lower end passes through a guide lug 144, Fig. 1, projecting from the standard 1, and be- 120 tween said lug and a suitable pin 145, or other means, is disposed a spring 146, normally acting to depress the rod 143 and hold the end 138 in the position indicated in Fig. 10, that is, with the locking piece 129 125 out of engagement or free from the slide bars, and the slotted end 137 in engagement with the toe 136 to thereby prevent rotation of the boot tree.

The lower end of the rod 143 is disposed, 130

see Fig. 1, so as to be met by the treadle or cam block 5 when the treadle 7 is depressed, so that upon depression of the treadle 7 and corresponding rearward or expanding movement of the slides 71, 72 and 73, the rod 143 will be lifted, thereby permitting the `locking piece 129 to engage the slots 128 in the slidesand also withdraw the slotted end 137 from the toe 136 so that the boot `tree,`while the parts are in expanded position, may be turned in its barrel 65.

As hereinbei'ore stated, when the treadle 7 is depressed, the treadle or cam block 15 is raised and the slides 71, 72 and 73 are drawn outward to jack the boot or shoe, said slides at such times having been moved from the position shown by Fig. 2 to that of Fig. 5, and locked in said position by the locking piece 129. With the parts in this position and the treadle or cam `block 5 also locked in its raised position by the locking pin 120, it is desirable that the tree be permitted to rotate on its axial mounting in the head or turret 30, and it is likewise desirable, when the tree has been thus rotated, that the turret be not allowed to turn, as will be readily understood by those skilled in the art.

To the above ends suitable automatic locking and unlocking devices are employed, one form of which is shown in detail by Fig. "9,

` wherein the hand'wheel 69 is provided with a locking recess 150, which, when the tree is in boot or shoe receiving or discharging position, as indicated by the upper tree in Fig. 1, engages a lock or catch 151 pivoted at 152 on a bracket 153 secured, as by screw bolt 154, to theturret or head 30. Bearing upon the lock or catch 151, so as to normally raise its outer end into locking engagement with the hand wheel 69, is the spring 155, seated in a suitable socket of the bracket 153, and adjustable as to its effective action by an adjusting scr-ew 156. The locking engagement vbetween the lock or catch 151 and recess 150 in the hand wheel is such, that,

' while it suiiices to position the hand wheel and tree with respect to rotative movement, yet a little force exerted by the operator on the hand wheel will disengage the lock or catch and permit the tree to be turned, and when the tree is thus turned the outer end of the lock or catch 151 rides upon the periphery of the hand wheel.

In order to prevent rotative movement of the turret 30 when the tree is turned, as stated, the inner end 157 of the lock or catch 151 is adapted to engage a locking recess 158 in an arm 159, projecting from the standard or column 1, but when the tree has been turned on its axis into initial position, at which time the toes or lingers 74 of the slide rods 71,72 and 73 will engage the slot 28 in their operating levers, the odk or catch 151 will rise at its outer end into engage-` ment with the notch 150, thereby freeing the turret to rotative movement.

Mounted on the slide bar 71 which serves to move the foot piece or oreparttoward the leg is a bracket or arm 160, Fig. 5, having a split bearing 161 for a tubular part 162 in which works a plunger 163 carrying a stem 164, said plunger being yieldingly retained in its retracted position within the tubular part 162 by means of a spring 165. At its end exterior to the part 162 the stem 164 is provided with a block 166 pivoted thereto, said block carrying the spring arms 167, the ends of which are adapted to engage lacing eyelets in the shoe being treated, as indicated in Fig. 5. Also secured to said block 166 are the spring arms 168, preferably two in number, connected at their outer ends by a tongue engaging loop 169, the construction being such that the tongue of a shoe being treated may be held by the spring loop 169 clear of the treeing tool and out of the way of the operator.

It is sometimes desirable to treat shoes of a different character from that indicated by dotted lines, Fig. 5, as for instance, so-called low shoes, in which case the arms 167 and tongue holder 169 would not extend far enough for such purpose. To meet this condition, the end of the tubular part may be provided with an extension 170, Fig. 7, to the lower end of which the tubular part 162 may be connected, as by screw threads and coupling sleeve 171.

From the construction described as one form of means embodying the present in vention it will be noted that with the parts in position as indicated in Fig. 1, and the foot piece forepart 104 connected to its slide, the operator can place a boot or shoe upon the foot piece forepart and engage the lacing eyelets and tongue with their holders 167 and 169 respectively. The treadle 7 is then depressed, thereby raising the cam block 5 and turning the levers 24, 25 and 26 upon their fulcrum or support 23, and withdrawing the slides 71, 72 and 73, the cams 20, 21 and 22 being so formed that the upper slide 71 will first move the forepart toward the leg 70, the middle slide 72 at such time moving with it but not relatively thereto, so that the cam projection 98 remains in position as indicated in Fig. 2. When the forepart reaches the limit of its movement toward the leg 70, the appropriate cam slot acts upon its lever to move the lower slide 7 3, thereby moving the heel part or member of the leg back outwardly from the forepart, and the middle slide is then similarly actuated to expand or enlarge the orepart by moving the sole plate 108 from the sole thereof.

It is to be noted that the expansion of the forepart is not a bodily movement thereof away from the heel member, but rather an i the machine is facilitated by simple treadle increasing of its dimension, which may be characterized as a movement to enlarge the forepart.

As the slides reach the limit of their expanding or jacking movement the cam block 5 meets the end of the rod 143, frees the lock piece 129 for engagement with the recesses 128 in the slides to lock the same in expanded position, and withdraws the slotted end 137 of the lever arm 138 from the toe 136, so that the tree can be rotated on its axis, to enable the operator to treat all parts of the boot or shoe. At such time the turret is held from rotation on the axis 29 by the lock 50 engaging a pin 55 on the turret. The operator, however, might depress the treadle 41 and by mistake attempt to turn the turret or head when the tree has been turned on its own axis from the position indicated in Fig. 1, but under such conditions the catch 151 has its end 157 in engagement with the recess 15S in the arm 159, and such action is prevented.

It may be the operator desires to unj ack a shoe after having fully depressed the treadle in order to adjust the boot or shoe or for other reasons, to do which he may depress the treadle 127, thus tripping the catch 120 and permitting the cam block 5 to drop and operate the levers to push in the slides 71, 72 and 73, and when he has adjusted matters satisfactorily he may again depress the treadle 7 and expand the tree as before.

Having finished a boot or shoe, and turned the tree on its own axis into initial position, the operator depresses treadle 41, whereupon the actuator 43 unlocks the turret and turns it to bring another tree into position. As the tree reaches working position, the ends 74 of the slides engage the notchesv 23 in the levers, and the trip or lug 24 on a tree moves the end 123 of lever 121 backward, thereby withdrawing the catch' 120 and permitting the cam block 5 to drop, thus permitting the rod 143 to withdraw the lock piece 129 from engagement with the slides 71, 72 and 73, and the slotted end 137 to engage the toe 136, and simultaneously therewith actuating the levers 24, 25 and 26 to unj ack the boot or shoe now brought into working position.

It will be noted that the turret and trees carried thereby are rotatable on substantially parallel axes, or, in other words, that the trees are collectively and individually rotatable about substantially parallel axes; that when a tree is rotated on its own axis from normal or initial position the turret or head is locked so that the trees cannot be collectively rotated; that the head or turret is turned or .rotated by treadle action which also controls a turret block; that the j acking and unjacking is under treadle controlled means; and that the entire action of operations leaving the hands of the operator free for manipulating the work.

lVhat is claimed is:

1.
