After the lasting operations havebeen com pleted and the last is removed from a shoe, the

shoeis ready for the treeing and shaping 0perationsowhich impart to it ishe ment-a-1: Heretofore, those: operations .have been carried out separately and on different machines.

Usually the shoe is first mounted onv atree leg of a,

the tree leg to dry whilesimilar operations are i being carried out on another .:treed :shoe, after:

which the firstisho-e is brushed and removed from the machine, @and, in the caseof some shoes such as pumps, for example, the width of. the iootreceiving shoeopeningis reduced in the 1 pressing. operation so that the top of theshoe will hug the foot of the wearer, and in the same operation the opening is :given a somewhatsyznmetrical appearance that is pleasing to the eye.

39 It is'an object, of this invention to provide a machine wherein-both the treeing and theshaping operations; may be carriedxtoutwithout removing a shoe from the machine and thereby save the timeswhichhas heretofore been used 5 changing aLshOe "from one machine to the other... To this end. the inventionzprovides a machine comprisingca shoe tree which is'mounted for movement abetweenia treeing a shaping position; and shoe pressingmeans ar- 40 ranged for shaping engagement. with a? shoei'o-n the shoe ;tree when :the tree is in the shaping position. This construction. makes it possible both to tree and to shape 'alshoe without removing itirom theshoe tree, andin additionalso 45 provides an arrangement whereby, a shoewhich has been dampened in the treeing operation may simultaneously be dried and shaped as the shoe. will be. drying while it is. being pressedloy the pressing means. i 50 As a further feature of this invention means are provided in the machine for utilizing an operators time when the shoe tree is in the shaping position. prises another shoe tree which is also .mounted as for movement between the treeing position and a ppearance before it is packed for shipposition and As illustrated, this means com.

shapingiposition, the disposition of the shoe trees being such that when one shoe tree is ina shaping position the other will 'be' in the treeing position thus making it possible for an operatorto carry out treeingop-erations on a shoe'on one shoe tree while a shoe on the other shoe tree is beingcr'dried and shaped.

In accordance withanotherfeatureof this invention, there is illustrated an improved mechanism for pressing and shaping shoe'uppers. In the illustrated embodiment of; this feature of the invention, the mechanism comprises shoe pressing means and a tree leg mounted for movement into and out of a shaping position where it may be engaged by the pressing means, the tree leg givea shoea restricted opening of pleasing appearance, and provided with heating means arranged to apply heat to a shoe-upper adjacent to the top opening thereof 'to facilitate the shaping and drying of a shoe on the form.

The illustrated machine is of the type shown in Letters Patent of the United States No. 442,034, granted December 2, 1890, upon application of A. E. Fowler, to which Letters Patent reference may be had for a description of parts of the machine not herein fully shown or described.

The illustrated machine comprises a bench I2 (Fig. 2) having an extensible standard I4 which carries a forwardly extending bearing plate I6 that has a semi-circular upright flange I8. The flange I8 has a central opening in which is slidably mounted a plunger 20 that controls the expansion of the shoe forms as will be explained fully hereinafter, the plunger 20 being moved inwardly to expand the shoe forms by a lever 22 which is actuated by a foot lever 24 through a connecting link 26. The bearing plate It is provided with a pivot stud 28 upon which is rotatably mounted a turret 30 (Figs. 1 and 2) having two hollow arms 32, 34 in which are journaled tree legs 36, 38. The swinging movement of the turret 30 is limited by a pair of stops 4!], 42 on the support plate I6 which are so located in the path of movement of 9. lug 44 on the turret 30 that when the lug is in engagement with one or the stops, one or the other of the tree legs will be positioned centrally of the machine where the treeing operations may conveniently be carried out by the operator. Each of the tree legs includes an expansible shoe form which is controlled by a reciprocating rod 46 (Fig. 1) having a collar 48 on its inner end which is slidably mounted in the inner end of the hollow turret arm. The reciprocating rod 46 is connected to the plunger 2!] by a cup shaped sleeve 55 which is slidably mounted on the rod 46 (Fig. 1) and a spring 54 interposed between the sleeve 50 and the collar 48, the sleeve 50 having a depending arm 5I (Fig. 2) in which is mounted a roller 52 that is engaged by the plunger 20 when the tree leg is in the central treeing position. Thus, inward movement of the plunger 20 is transmitted to the rod 46 by the sleeve 54 and the spring 54. The rod 46 is urged outwardly by a spring 59 which is sleeved 0n the rod between a plug 60 threaded in the inner end of the tree leg and a collar 62 fast to the rod. The forward ends of the hollow arms 32 and 34 are provided with longitudinal slits 53 (Fig. 2) and the shoe trees are clamped in different rotative positions by clamping wheels 54 or 55 mounted on the respective arms. The trees are held against longitudinal movement in the hollow arms by studs 56 or 5'! (Figs. 1 and 2) which are seated in peripheral grooves 58 formed on the inner ends of the treeing legs. The structure so far described is similar to that disclosed in the above-mentioned patent to Fowler.

As the shoe trees are similar to one another only one of them will be described in detail and like parts in both shoe trees will be given the same reference characters. The shoe tree consists of an upper leg portion 66 (Fig. 1) and a lower leg portion Ill, the inner end of the upper leg portion being attached to the hollow turret sleeve 32 by pins 61 and the other end of the upper leg portion being flared outwardly and provided with an electrical terminal box 68 having projecting brushes 80. The lower leg portion it is provided with an extension 72 on its inner end which is journaled in the hollow arm 32 of the turret 30 and has mounted on its outer end an expansible shoe form I4 which is provided with an electrical heating unit I6. To supply the heating unit 16 with current in all of the rotative positions of the tree leg, the lower leg portion ll] is provided with an outwardly extending dished housing TI in which are mounted collector rings I8 disposed in a path of the brushes as depending from the terminal box 68 (Fig. l); the collector rings being connected with the heating unit It by a cable I9.

To assist in attaining that object of the invention, which relates to reducing the width of the top opening of a shoe and giving it a pleasing appearance, the section of the shoe form I4 contiguous to the shoe opening is given the shape which it is desired to have the shoe take. In the illustrated embodiment of this invention, this shape comprises a curve of short radius (Fig. '7) at the rear or heel end, a curve of larger radius at the throat and straight sides interconnecting the ends of these curves, the sides being nonparallel and diverging toward the front. sides also slope inwardly in a heightwise direction (Figs. 4 and 5) in the area adjacent to the top edge of a shoe.

The expansible shoe form I4 (Fig. 3) consists of a rear portion 82 which is attached to the tree leg 36 and a forepart 84 that is slidably mounted on the rear. portion 82 and is operatively connected with the reciprocating rod 46. The forepart 84 consists of a wooden form (Fig. 3) having a central groove in which is fastened a metal channel strip 86 shaped to slide on the T-head 92 (Fig. 4) of a carrier I00, the metal channel strip extending beyond the rear end of the form 84 and the extending portion having an opening therein for engagement with a latch 90 on the head 92 (Figs. 3 and 4). The carrier I00 is provided with flanges 94 and 96 which are slidably received in grooves formed in the rear portion 82 (Fig. 4) and is moved back and forth in those grooves by the reciprocating rod 46 which is connected to the carrier me by a gear train that consists of (Fig. 3) a rack 41 on the rod 46, pinion I 02, gear segment 98 and rack IilI on the carrier I00. With the abovearrangement the tree legs are adapted to cooperate with a range of sizes as foreparts of different sizes may readily be interchanged by releasing the latch 90 and removing one forepart and replacing it with another of a different size.

To support the top edge of shoe uppers back of the throat portions, metal plates I04, I06 are provided on the shoe forms which extend from the forepart 84 back about half way to the heel. These plates are slidably mounted on tracks Hi8, IIU (Fig. 3) in recesses on the sides of the rear portion 82 of the shoe form and are connected with the gear segment 98 for movement with the forepart 84 by a pin H4 which is mounted on the gear segment with its ends seated in recesses H2 (Fig. 4) in the plates I04, I06. Thus, the metal plates I I14 and I06 will be moved simultaneously with the forepart 84 by the gear segment 98. Forward movement of the plates I54, I06 will uncover the recesses in which they are seated and to cover theserecesses thin cover plates H6 (Figs. 1 and 7) are attached to the rear portion 32 and extend between the rear ends of the slides and the rear part of the shoe form. The portion I55 (Fig. 4) of the plates I04, I06 which contacts the shoe upper lining adjacent to the top line and also the side sections of the rear portion 82 of the shoe form are sloped inwardly so that when an upper is pressed against The the sides of the shoe form1-(Figs'h5 .andfl); in the shaping operation I which .will ,subsequentlybe, described; the shoe-openinggwill be reduced:- In the illustrated machineuthe :rear. 113311352. of? the".

line of the shoe. Another feature of the inven- ,tionllies in the shapeaofthe rear or heel section 82 of the shoe form which is made narrower than the opening of the shoe upper so that when the top portion of the upper. is pressed against the sides of the form-the lower portion of the heel section of the upper, which is reinforced by a counter, will be bent gradually inward ,(Fig. 5) Thus,,when the pads-.are moved away from the by widening the heel portion of the shoe opening understood, however, that the shape and dimen-.

also those, of the presser pads may be varied so that all or any desired part of the shoe upper, can be supported and pressed without departing from the spirit of this invention.

The operation of the 1113611111615 as follows:

A forepart "84 of an appropriate size. is first selected and is slid overthe head 92 of the carrier ,Idil and is fastenedthereon by the latch 9E3, the connections being as shown, in Fig. 3.v A shoe is thentplaced upon the treeleg which is in the centralror, treeing position, that, is, in the position occupied by the leg 36 in Fig. .1;;and the lever 2'1 is depressed to expand theshoe form by actuating the control, system in the following manner. Downward movement of the lever 24 causes rotation of the lever 22 (Fig.2) which moves'the plunger 20 inwardly carrying the roller 52 andsleeve .50 inwardly with, it. thereb y compressing the spring 5 3 (Fig. 1) and through .it, moving the rod 6 and rack 4'1 inwardly;v movement of the rack i! in this direction will be trans-.

mittedtto. the carrier Hill and theiorepart 34 will be'moved forwardly to, expand the shoe form a desired'amount. The sideplates IM, tilt are moved with the forepart by the pin ,i M (Fig. 4) which :is carried by the gear egment 98 and is ,seatedgin recesses-II2 in the plates. shoe-form has been expanded, the shoe tree is ,After the rotatedabout its axis by the operator as. desired for the treeing operations and upon the completion of these operations the shoe islmoved to a horizontal position with the heel pointing toward wthe adjacent presser pads; This. is necessary.

because the shoe form is is shaped so that the sides "diverge outwardly from the heelnto the throat portion and the presser pads I28, It?) are arranged to receive the shoe form between them stop ill when the tree leg 38 will be in the treeing position where its shoegform M will be located between the presser pads I28 and I36. The appropriate treadle I42 will now be depressed to "move the pads against the sides of the shoe on the shoe form with a wiping action which presses The turret 3B is then swung I until the projection Mi on the turret engages the position formerly occupied by the tree leg 35 and i 65 the tree leg 3% will be moved to a shoe shaping I to hold the pads in pressing engagement with the shoe upper while a shoe which has been shaped on the other shoe form is being brushed, removed from the form and another shoe is placed upon the form and the appropriate treeing operations are carried out. Pressure from the pads will cause the shoe to take the shape of the shoe form which will result in reducing the width of the shoe opening and giving it a symmetrical appearance. The heat from the shoe forms will accelerate the drying of shoes which have been dampened in the preceding cleaning operation and the concentration of the heat in the area adjacent the shoe opening will have a shrinking effect on the area of the upper around the top line of the shoe which will tend to reduce the shoe opening and. will assist the pads I28, H30 in shaping the shoe opening. After the shoe treeing operations are completed on the shoe mounted on the tree leg 38, the presser pads I28, V38 will be released from engagement with the shoe on the tree leg 36, which is now dried out somewhat in addition to being shaped, and that leg will be swung back into the treeing position where the shoe will be brushed and removed from the shoe form. When either of the shoe trees is out of the central position, the shoe form is held in its expanded position by the engagement of the roller 52 with the flange it which prevents the forward movement of the roller 52 and its sleeve 50 that would permit a like movement of the rod 46 and the accompanying contraction of the shoe form.

While the turret is pivoted in the machine chosen to illustrate this invention, the use of the shoe shaping means disclosed herein is not limited to a machine of this type but it is contemplated that it may be used in conjunction with other forms of shoe tree mountings, such as those which are slidable or movable otherwise. All that is necessary in any event is that the shoe form be available to the shoe shaping means either before or after the treeing operations, preferably after.
