To all whom it may concern:

Be it known that I, ERASTUS E. VIN KL'EY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Treeing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to finishing or treeing machines which are used in the manufacture of boots and shoes to finally dress, finish, and shape the surface of the uppers.

The operation of finishing or treeing is considered an important one in the production of shoes for the attractive appearance of the shoes desired by the trade depends largcly upon the skill and care with which it is carried out, and, although a number of treeing machines have been devised for mechanically finishing the uppers of shoes, their operation is usually performed by hand. in the hand method of treeing shoes the shoe is placed upon a tree which is expanded to fill out the interior of the shoe, and the operator, using various tools, imparts the final finish and shape to the upper. During the operation, the operator grasps the tool by a pair of handles and rubs the wrinkles out of and the dressing material into the surface of the upper by short vibratory movements of the tool applied locally to the surface of the upper. As he rubs, the operator transfers the point of operation along the upper, at the same time sliding and tilting the tool to bring it into the proper position for treating the straight portions at the counter extending vertically of the shoe, the straight portions extending horizontally over the vamp, the transverse and longitudinal curvatures along the welt and rand crease, and the lateral curvatures of the upper across the shoe.

The object of the present invention is to provide an automatic treeing machine by which a rapid and efficient shaping of the upper to the surface of the tree and finishing of he upper at the point of operation may be eifected by a tool having operating movements similar to the movements of the tool in the hand method of finishing shoes.

To this end the invention contemplates the provision in an automatic treeing machine of a shoe supporting tree, a tool for treating the upper of a shoe on the tree, mechanism for relatively actuating the tree and tool to cause the tool to reach and treat the surface around and across the upper of the shoe, and mechanism for rapidly vibrating the tool as the pointof ope 'ation is transferred The specific manner in which the vibrating tool is mounted and arranged, so that a rapid and efficient shaping of the upper to the surface of the upper at the point of operation is effected, is not essential, and may be varied as found desirable or expedient. It is desirable, however, to mount the tool so that it swings slowly from and toward the sole across the upper of the shoe as the point of operation is transferred along the shoe, and so that it rocks as it swings to maintain the pressure of the tool normal to the surface of the upper at the point of contact, and these manners of mounting the tool form additional features of the invention.

The invention also conten'iplates actuating either the tool or tree, or the tool and tree, to transfer the point of operation around the shoe, but on account of the simplicity of constructioi'i it is preferred to swing the tree longitudinally to transfer the point of operation along the sides of the upper and to swing it laterally to transfer the point of operation around the toe and heel portions of the upper.

A further object of the invention is to provide an automatic treeing machine in which the uppers of shoes may be finished without any work on the part of the operator except the placing of the shoe upon a shoe supporting tree and the removal of it therefrom after the treeing operation is com pleted.

With this object in view, a feature of the present invention contemplates the provision in an automatic treeing machine provided with tools and a series of shoe supporting trees mounted on a turret, of mechanism for automatically indexing the turret to pre sent the shoe on each tree successively to the tools. A machine embodying this form of turret actuating mechanism for indexing the turret relieves the operator of the work of starting any mechanism for indexing the turret, and permits the operator to give entire attention to the removal of a finished shoe from and placing of a new shoe on the shoe supporting tree between the automatic indexing movements resulting in an increase in the capacity over former treeing machines.

The various features of the present invention will be clearly understood from an inspection of the accompanying drawings, in which Figure 1 is a view in front elevation'of an automatic treeing machine embodying the invention; F 2 is a view in side elevation of the machine illustrated in Fig. 1; Fig. 3 is a plan view; Fig. t is a central vertical sectional view looking toward the rear, Fig. 1; Figs. 5, 6, 7 and 8 are sectional plan views on the lines ez, 2 wa1, and ww, Fig. 4, respectively; Fig. 9 is a view in perspective illustrating the turret pedestal and associated parts; Fig. 10 is a central vertical section illustrating the mechanism for actuating the tool carrying head; Fig. 11 is a sectional view at line oo, Fig. 10; and Fig. 12 is a sectional view through the cylindrical rack on the main shaft.

The machine illustrated is provided with a series of tools adapted to operate upon shoe uppers in performing successive operations incident to the tleeing or finishing of shoe uppers. The shoes are presented successively to the tools by a series of trees carried by a rotary head which is intermittently given a partial rotation 01' indexed to bring each tree successively into cooperative rela tion with each tool, so that different shoes are simultaneously presented to diiferent tools, and the same shoe successively presented to the different tools. The relative movements between the tools and trees to transfer the points of operation of the tools lengthwise or longitudinally of the shoe, or to vary their relative positions in accordance with the longitudinal curvature of the trees, are effected by imparting longitudinal movements and lateral swinging or rotary movements to the trees while held in cooperative relation to the tools. The relative movements between each tool and the cooperating tree to transfer the point of operation of the tool across the upper of the shoe, to vary their relative positions in accordance with the lateral curvature of the tree at the point of operation, and to compensate for the variations in the width and height of different parts of a shoe, are effected by movement of the tool as its point of operation is transferred lengthwise of the shoe.

As shown, the machine is pr vided with four supporting trees 1, the specific construction of which is not illustrated. These trees may be of any well-known or suitable construction, and may be provided with the usual expanding and contracting devices (not shown). The machine is also provided with three tools for erforming successive operations on. the shoes. These tools may consist of any device or combination of devices suitable for performing the intended operations upon the shoe. For instance, the first tool may be suitably constructed to apply a dressing and rub it into the upper, the second tool to iron the upper, and the third tool to wipe and finally finish and shape the upper to the tree. In the drawings the tools are indicated as rolls 2, 3 and 4, to which similar movements are imparted as their points of operation are transferred over the shoe uppers. This form of tool, however, is shown merely for illustrative purposes.

The four trees 1 are carried upon cylin drical arms 5, projecting horizontally from a rotary head 6. The head is provided at its lower end with a sleeve T which surrounds a bearing 8 formed on a vertical standard 9 and rests upon a horizontal shoulder 10 on the standard. The tree carrying head is indexed or given a partial revolution to bring the different trees successively into position to cooperate with the different tools through a gear 11 formed on the lower end of the sleeve 7, and engaged by a gear 12 secured to the upper end of a vertical shaft 13. The lower end of the shaft 13 carries a gear 14: which meshes with a cylindrical rack 15 formed on the hub of a cam drum 16 (Figs. 3, 6 and 12). The cam drum is mounted to turn with and slide on the main cam shaft 17 of the machine, and is provided with a cam groove 18 which is engaged by a fixed roller 19. The cam drum is connected with the shaft 17 by a segmental block 20 which is secured to the shaft and is arranged in a slot formed in the cylindrical rack 15, the outer surface of the block 20 being toothed to form a continuation of the rack 15. The cam slot 18 is so shaped that during the revolution of the shaft 17 the cam drum and connected rack 15 are moved toward the left in Fig. 6, while the teeth on the rack 15 are in engagement with the gear 14. This move ment of the cam drum rotates the gear 14:, and through the gearing described indexes the tree carrying head. The cam drum 16 is moved toward the right in Fig. 6, pre paratory to the next succeeding indexing movement while the teeth of the block 20 are in engagement with the gear 14, so that the indexing rack 15 is returned to initial position without imparting movement to the gear 14 and connected tree carrying head.

Each of the trees 1 is pivotally supported at 21 upon a support 22 secured to the outer end of a shaft 28 journaled in the arm 5 (Figs. at and 7). The inner ends of the shafts 23 are provided with pinions through which rotary movements are imparted to the shafts 23 and the trees carried thereby to transfer the points of operation of the tools around the heels or around the toes of the shoes, or to swing the trees laterally as the tools travel along the sides of the shoes. The pinions 24:, corresponding to the three trees which are in cooperative relation with the three rolls, are in engagement with three racks 25 formed on ribs which project radially from a rack bar 26 arranged to slide vertically within the upper end 9 of the standard 9 (Fig. 9). The fourth pinion 24, which corresponds to the tree which is out of cooperative relation with the tools and is in position for the removal of a finished shoe from the tree and the placing of a new shoe upon the tree, engages annular teeth 27 formed on the periphery of the standard, and so arranged that they register with the teeth of the racks 25 when the trees are in their upper or indexing position. During the indexing, the pinions 24 travel around the upper end of the standard 9 while in engagement with the annular rack teeth on the standard, and are thus held from rotation and brought successively into engagement with the racks 25. The rack bar 26 is moved vertically at proper intervals to rotate the trees by means of a cam groove formed in the cam disk 28 which is shaped to impart the proper movements to the rack bar through suitable connections. As shown, the cam groove engages a roll on the end of an arm 29 which extends upward from a sleeve 30, and the sleeve is provided with a horizontally extending arm 31, the end of which is connected by a link 32 with the lower end of the rack bar.

Each tree 1 is swung about the pivot 21 to transfer the point of operation of the tool lengthwise or longitudinally of the shoes through a lever 33 pivoted on the support 22, the upper end of which carries a roll 34 which engages a slot formed in an arm 35 projecting upward from the rear end of the tree. The lower end of the lever 33 is connected by a link 36 with a sleeve 37 which is mounted to slide and turn upon the cylindrical arm 5. This sleeve is provided with an annular groove 38 which is engaged by rolls carried in the arms of a yoke 39 formed at one end of a bell crank lever 40. The bell crank lever 40 is pivoted at 41 upon an arm projecting from the head 6, and the end of the lever is connected by a link 42 with a second lever 43 which is pivoted to an arm 44 also projecting from the head 6. In order that the longitudinal movement of the tree may be varied in accordance with the size of the shoe being operated upon, the pivot at the lower end of the link 42 is adjustably secured in a segmental slot 45 formed in the lever 43. The levers 43, corresponding to the trees which are in cooperative relation with the tools, are operated by means of a vertically reciprocating actuating block 46 mounted to slide within the standard 9 and provided with three radially extending lugs 47 which play in vertical slots 48 formed in the bearing 3 of the standard (Fig. 9). These lugs are provided with circumferentially extending slots arranged to be engaged by rolls 49 (Figs. 4 and 5) carried on the inner ends of arms 50 which project laterally from the levers 43 and extend through vertical slots formed in the head 6. The bearing 8 of the standard 9 is provided with an annular groove 51 so arranged that it registers with and forms a continuation of the circumferential slots in the lugs 4? when the actuating block 46 is in proper position for the indexing of the tree carrying head. The roll 49 on the lever 43, corresponding to the tree which is not in cooperative relation with the tools, lies in a part of this annular slot so that the tree corresponding to this lever is held in fixed position during the operation of the tools upon the shoes carried by the other trees. During the indexing, the rolls 49 travel around the annular groove 51 so that the trees are held in fixed position during the indexing, and are successively connected with the lugs 47 by the successive indexing movements. The proper vertical movements are imparted to the actuating block 46 by a cam groove formed in the cam drum 28 and arranged to engage a roll 011 the end of an arm 52 which is secured to a rock shaft 53 carrying an arm 54 connected by a link 55 with the lower end of the block.

Each of the tools 2, 3 and 4 is mounted between the arms of a tool carrying yoke 56 which is supported upon the free ends of rods 57 held by their other ends in sockets in a bar 58. These rods 57 normally tend to force the tool forward toward the medial line of the shoe, and are held at one end only to permit them to bend and twist under the pressure of the work. These rods thus act as springs to hold the tool yieldingly against the surface of the upper, and automatically adjust its position in accordance with that portion of the upper with which it has engagement. The rod supporting bar 58 is guided in guideways 59 formed on the inner faces of the sides 60 of a head (31, and is connected by means of a rod 62 with a block 63 mounted to reciprocate in the lower end of the head (31. The block 63 is connected to an eccentric 64 on a shaft 65 through a link 66, one end of which is attached to the strap of the eccentric, and the other end of which is connected by a ball and socket joint with the block. During the operation of the ma chine the shaft 65 is driven to rapidly reciprocate the carrier yoke 56 and thus impart rapid vibratory movements to the tool carried by the yoke.

In order that the position of the tool may be varied in accordance with the various curvatures of the upper at the point of operation, the head 61 is carried by a support 67 mounted to swing about lateral and transverse axes arranged at right angles. he lateral swing of the support moves the tool in the direction of the height of the shoe to accommodate the tool to the varying heights at different portions of the upper, and also to transfer the point of operation of the tool across the vertical portions of the upper. The transverse swing of the support 67 moves the tool in the direction of the width of the shoe to accommodate the tool to the varying widths of different portions of the upper, and also transfers the point of operation over the horizontal portions of the upper. As the lateral and transverse axes are arranged at right angles, the support 67 is practically mounted for universal movement so that a combination of the lateral and transverse movements of the support swings the head 61 carried thereby to move the tool across the various portions of the upper of the shoe.

In order that the pressure of the tool may be maintained normal to the surface of the upper at the point of operation as it is swung across the upper, the head 61 is mounted to turn and rock in the support 67 about an axis passing through the point of operation of the tool substantially parallel to the direction of movement of the tool lengthwise or longitudinally of the shoe. As shown, the head 61 is provided with a cylindrical lower portion mounted to turn or rock in a vertical bearing formed in the support 67. The lower end of the head 61 projects below the bearing 67, and a gear 68 is secured to this end of the head. The gear 68 is engaged by a gear segment 69 carried by the base plate 7 0 on which the support 67 is mounted. The segment 69 is operated to impart rotary or rocking movements to the head 61 as the point of operation of the tool is transferred along the shoe by a sleeve 71 connected by a link 72 with the gear segment. The sleeve corresponding to the tool 4 is connected by a bell crank lever 73 with a slide bar 74 mounted in a vertical groove formed in one side of the standard 9. The sleeve 71 corresponding to the tool 2 is connected through a similar bell crank lever 75 with a similar slide bar 76 mounted in a vertical groove in the opposite side of the standard 9. The sleeve 71 corresponding to the tool 3 is connected with the two slide bars 74 and 76 by an arm 7 7 connecting the sleeve with a rock shaft 78 which is connected with the slide bars 74 and 76 by arms 79 (Figs. 2 and 8). The slide bars 74 and 76 are actuated to impart proper rocking or tilting movements to the tools by a cam groove formed in a cam disk 80 and engaged by a roll on the end of an arm 81. The arm 81 is secured to a rock shaft 82 which is connected by arms 83 with slide bars 74 and 76.

In order that the tools may be moved forward and back in the direction of the height of the shoe to transfer the point of operation across the vertical portions of the upper, and to compensate for variations in the height of different parts of a shoe, each of the supports 67 is mounted to swing laterally upon the base plates 7 O, the gear 68 being rounded off to permit the teeth thereof to rock in engagement with the teeth of the gear segment 69. As shown, each base plate is provided with trunnions 84, and the supports 67 are provided at their lower ends with arms which extend down on opposite sides of the base plate and are provided with bearings engaging the trunnions 84. The proper lateral movements are imparted to the support 67 through links 85 connecting the supports with the upper ends of levers 86, the lower ends of which are connected with sleeves 87 mounted to slide on shafts 88 connected to the base plates 70. The sleeves 87 are connected by bell crank levers 89 with a cylindrical slide 90 arranged within the lower end of the standard 9 and connecting the bell crank levers so that they are operated in unison. The lever 89 corresponding to the tool 3 is provided with an arm 91, the lower end of which is connected by a link 92 with an arm 93 secured to a rock shaft 94. An arm 95 is also secured to the rock shaft 94, and is provided with a roll engaging a cam groove formed in a disk 96 and shaped to give the proper rocking movements to the tools through the connections described.

In order that the tools may be moved forward and back in the direction of the width of the shoe to transfer the point of operation across the horizontal portions of the vamp. and to compensate for variations in the width of different parts of a shoe, each of the base plates 70 is mounted to swing transversely upon the machine frame. As shown, the shaft 88 connected to each base plate is mounted to rock in a bearing 97 formed in the standard 9, and each base plate is provided with a trunnion 98 mounted to rock in a pedestal 99. The base plate 70 corresponding to the tool 4 is provided with an arm 100 which carries a roll 101 engaging a cam groove formed in a disk 102 and shaped to give the proper rocking movements to the tool 4. Each shaft 88 is provided with a bevel gear segment 103 formed on a bracket 104 pinned to the shaft, and each segment meshes with a bevel gear 105 loosely mounted on the standard 9. Through these connections, transverse rocking move ments are imparted in unison to the tools 2, 3 and 4.

The mode of operation of the machine is briefly as follows: During the time that the tools are operating upon the shoes carried by the trees which are in cooperative relation with the tools, the tree which is at the front of the machine remains stationary, and the operator removes a finished shoe from this tree and places an unfinished shoe upon the tree and expands the tree to hold the shoe, in the usual manner. During the interval between the successive indexing movements of the tree carrying head, each tree is swung downward to carry the point of operation of the tool longitudinally or lengthwise of the shoe carried on the tree. During this movement the tool is rapidly vibrated. while held yieldingly in engagement with the shoe upper, and the support (37 is rocked slowly forward and back laterally and transversely to transfer the point of operation across the various portions of the upper of the shoe, the head 58 being rocked so that the tool is pressed against the upper in a direction substantially normal to the surface at the point of contact. lVhe-n the heel is reached, a rotary movement is imparted to the tree to transfer the point of operation of the tool around the heel, and then the tree is swung upward to transfer the point of operation lengthwise along the other side of the shoe, the support 67 and head 58 being again actuated to transfer the point of operation of the tool across the shoe, and to maintain the tool in proper re lation to the surface of the upper at the point of operation. When the toe is reached, a second rotary movement is imparted to the tree to transfer the point of operation of the tool around the toe. After the points of operation of the tools have been thus transferred over the portions of the shoe upper which are to be finished and shaped to the trees, an indexing movement is imparted to the trees.

The term vibrating tool is used throughout the description and the claims in the same manner as used by those skilled in the art in describing a tool having rapid oscillatory movements of small amplitude.
