EDGE-SETTING MAGHINE; &

Toiall whom it-ma'y concern:

B it known ,thatywe, ERAsrUs ENVINK- LEY and Benjamin PHILLIPS, citizens of the'United States, residing at Lynn, in the county of Essex'and State of Massachusetts,

have invented certain'new and useful Improvements in' Edge Setting Machines; and

We do hereby declare the following to be a full, clear, andexact description of the invention, suchas will enable others-skilled in the art to which it appertains to make and' use the same. V

I The invention relates to machines for setskill or care on the part of the operator. l

To this endonef eature of the invention contemplates the" provision in a machine provided with a shoe sup orting jack of a plurality of edgesetting evices the points of operation of which are transferred along different parts of the sole edge by a relative movement of the jack and setting devices While rapid relative movements are being imparted to the jack and setting devices to efiectively rub or burnish the edge as the point of operation is transferred along the sole. The burnishing movements of the setting devi ceswitli 'relation to the sole edge secure a rapid and uniform finishing of the edge" at the point of operation, while the provision of a plurality of such rapidly operating edge setting/devices for operating upon different parts of the shoe enables the burnishing of the 'sole edge to be quickly completed.- i

It is irsual in the manufacture of boots and shoes, and especially 'of the better grades, to give th'e sole edge a different shape along the shank from'that given to the soleedge around the iorepart of-the shoe.,

The. burnishingor setting of the sole edges 1 of such shoes .th'ereforerequires the use of differently sha ed setting devices in operating upon thed ifferently shaped parts of "the sole edge.

Accordingly a further feature of the invenv tion contemplates the provision in a machine in which relative burnishing movements and relative movements toltransfer thepoint of op-. eration along the sole edge, are imparted'to a shoe supporting jack and edge setting devices,

of edge setting devices having sole: engaging different partsofthe ble edge. It is not material to this feat-u e of the invention,

broadly considered, whether the differently shaped facesof the setting devices actupon they different partsof the sole edge simultaneously or successively. In the preferred embodiment of -the invention, however,'the difierently shaped faces of the setting devices act successively on the different parts of the shoe sole, and means re provided for shifting the edge setting de ices to bring the" ing upon the sole edge 'on opposite sides of theshoe, and of a separateed e setting tool for operating upon the soles ge at the toe of the shoe, and the invention also.contemplates the provision of separate jacks and edge setting devices for right and for left shoes.

'Other features of the invention will be noted in connection with the description of the illustrated embodiment thereof.

Fig. 4 is a side elevation showing in detail one of the jacks and the mechanism for rtetuating the shank and'forepart tools; Figs.

5 and 6 are respectively a plan view, and a front elevation partly in section, showing in, detail a portion of the mechanism for. actuating the shank and forepart, tools; Fig. 7 is a plan view showing in detail the edge-setting tools and portions of their actuating mechanism; Figs. 8 and 9 are respectively a side elevation and a rear elevation 'of the mechanism for actuating the toe tool.

The illustrated embodiment of the invention is a duplex machine being provided with two jacks and two sets of edge-setting tools, and being. adjusted to operate upon right-hand shoes -iipon one jack and left hand shoes upon the other. The jacks ar'' I similar in construction. As shown particuoted a'heel pin 2, which enters a socket in larly in Fig. 4, eachja'ck comprises a heel post 1, upon the upper end of which is pivthe lastand is pressed forward by a spring. plunger 3 so as to tilt the shoe against the toe support. The heel post slides vertically in a sleeve 4 fixed to a slide 5 mounted upon horizontal ways -'6 upon the bed plate 7 of the jack. The slide 5 may be moved horizontally on the ways 6 to accommodate the jack to shoes of differentlengths, and by means of a hand screw S it is fixed in adusted position. The toe post 9carries, at its upper end the toe support-10, which-is provided wlth circular curved'ribs 11 loosely engaging corresponding grooves in the raised so as to press the shoe upward against the fixed heel and toe rests 14 and 15. The heel rest 14 is provided with a rocking arrangement 16 like that of the toe support, and is mounted upon an arm 17 projecting from the frame of the machine. The toe rest 15 is similarly mounted upon an arm 18. The compensating lever (see Fig. l) is mounted upon the upper end of a rod 20, slidingly mounted in the frame of the machine, and the-lower end of the rod 20 is embraced by a sleeve at the upper end of a link 21 pivoted at its lower end to a treadle lever 22. A sliding collar 23 on the rod 20 engages the lower end of a compression spring 24 which bears at its upper end against a collar fixed on the rod 20. A catch 25 is pivoted upon the frame of the machine in position to engageand retain the collar 23 when it is moved upward to compress the spring 24, and a hand lever 26 is connected with the catch to release' it when necessary.

To insert and secure a shoe on the jack the bed plate 7 is drawn toward the operator along horizontal ways on a bracket'19 pro- ]ecting from the frame of themac hine, and

the lasted shoe is then placed upon the heel.

post. The bed plate of the jack is then pushed back until the toe is in position under the toe rest and the operator then depresses the treadle, thereby compressing the spring 24 which operates through the rod 20 and compensating lever 13 to raise the heel and toe post and press the shoe upward against the heel and toe rests. The catch 25 engages the collar 23 and maintains the jack in this condition until released by the hand-lever 26.

In connection with each jack there are provided edge-setting tools.of three kinds. the shank tools for burnishing the sole edge The toe from the heel to the juncture of thei s'hank and theforepart, the forepart tools for burnishing the sole edge from 'the'latter oint to the toe, aridthe toe tool forburm' lshing the forward extremity of the soleedge. The shank and ,forepart tools are mounted upon heads 27 (see Figs. 4 and'?) fixed to the forward ends of shafts 28 journaled in sleeves 29. The rear'extremities. of the sleeves 29 are provided. with forks 30 pivoted in uprights 32 (see Figs. 4, 5 and. 6) upon sleeves 33 rotatably mounted in sleeves 34 projecting downward from slides The slides are provided with flanges 36 engaging corresponding ways on the frame of the machine, so that they may be moved longitudinally with respect to the shoe to transfer the point of operation of theedge setting tools along the sides of the shoe.

The pivotal mounting of the sleeves 29 per? mits' the tools to rise and fall in accordance with the contour of the sole edge as the-tools are moved longitudinally with respect .to the shoe. To maintain the tools in contactwith the sole edge each sleeve 33 is provided with an arm 37 to which is connected one end of a spring 38. the other end being fixed to the slide 35. This spring tends constantly to swing the sleeve 29- in a direction to press the tool against the'sole edge. The burnishing tools are given a constant vibration along the sole edge of slight amplitude to facilitate the burnishing operation. For this purpose the rear ends of the shafts 28 are connected'bv universal joints 40 with links 41 pivotallfv connected with eccentric straps 42 engaging eccentrics 43 on shafts 44, j ournalecl in uprights 45 on the slides 35 and provided with suitable driving pulleys 46. This arrangement is such that a constant and rapid vibration may be im parted to each tool without interference with its several other movements. I

In order that the operation'may proceedfrom the heel to the toe of the shoe it is necessary to impart to the tools, in addition to their vibrating movement above described,

a general movement longitudinally with respect to the shoe, and for this purpose the slides 35 are moved horizontally in the frame of the machine. As shown in Fig.

4, the slide of the right-hand lastis connected by means of a short link 47 with the upper end of a lever 48 fixed (as shown in Fig. 1) upon a rock shaft 49 j'ournaled in the frame of the machine. This rock shaft lever is actuated by a cam 50 on the cam shaft 51 of the machine through suitable connections to be described later.

As shoes are usually finished with edges of different form in the shank'and in the forepart, it is necessary, after the edge has been burnished front the heel to the forepart. to substitute a different tool to operate upon the forepart, and the present machine is provided with shank tools 52 and forepart tools 53. These iools are mounted upon a short shaft 39 loosely journaled in the head 27, so that the toolsinayturn to accommodate themselves to the inclination on the sole edge, and means are provided for automatically substituting the forepart tool for the shank tool at the proper time in the operation of the machine by imparting a half rotation to each of the shafts 28. For this purpose each shaft is provided with a gear wheel 54 located at the rear extremity of the sleeve 29 and splined to the shaft 28. This gear engages a toothed sector on a bell-crank lever 55 pivoted at 56 in the sleeve 33 and having a lateral arm connected by means of a link 57 with a lateral projection from a sleeve 58. The sleeve 58 slides vertically upon a rod 59 fixed at its upper end to the sleeve 33. The lower end of the sleeve is grooved, and is engaged by the forked end 62 of a bell-crank lever journaled at 63 on a bracket 64 mounted on the slide The bell-crank lever carries a cam roll (35 engaging a cam path 66 in a cam disk (37. The cam is mounted upon and splined to a cam shaft 68 passing loosely through the bracket 64 but fixed against longitudinal movement at its rear end, (see Fig. 1) where it is journaled in the frame of themachine. In order that the forepart tool may be substituted in this manner for the shank tool it is necessary to swing the latter out of engagement with the sole edge, which is accomplished by turning the sleeve 33 slightly in the slide 35. and for this purpose the arm 37 is provided with a cam roll 69 engaging a cam path 70 (see Fig. 4) in the cam 67. It is also necessary before swinging the shank tool out of engagement with the sole edge to lock the sleeve 29 in its vertical position with respect to its pivotal connection with the uprights 32, in order that the forepart tool when substituted for the shank tool may occupy the same vertical position as was occupied by the shank tool, corresponding to the height of the sole edge at the point of change. To this end the rock shaft 31 (see Fig. 6) upon which the fork 30 is mounted, is keyed to the fork. and upon its outer end is fixed a depending arm 72 carrying a curved friction surface 73 in position to be engaged by a corresponding brake shoe 74. The brake shoe is mounted upon a horizontal lever 7 5 pivoted to the upright 32 at its outer end its inner end with a link 76 bearing upon a lever '77 pivoted upon the bracket 64 and carrying a cam roll engaging a cam path 78 in the cam 67.

r The operation of the mechanism just described issuch that when a partial rotation in the direction of the arrow, Fig. 6, is imparted to thecam 67 by the rotation of the cam shaft (38, the sleeve 29 is first locked in and connected at its vertical position, then swung outwardly from the shoe to remove the shank tool therefrom and then a half rotation is imparted to the shaft 28 to reverse the positions of the tools. The sleeve 29 is then allowed to swinginward again until the fcrepart tool engages the sole edge a d the brake shoe Ttthen disengages the riction surface 73. After the edge-setting operation has proceeded from the heel to the toe,

a partial reverse movement of the cm 67 takes place, thereby substituting the shank' tool for the forepart tool in readiness for the operation upon another shoe. But the cam dwells in such position as to leave the shank tool out of contact with the sole edge and fixed in its vertical position, to permit the finished shoe to be removed and a new one to be inserted. After the machine is again set in operation. the cam 67 at once completes its return rotation to the p sition of Fig. 6. to permit the shank tool to engage the sole edge.

The mechanisms above described are repeated for each pair of tools, there being four such pairs in the (\UDlQX machine, and the four cam shafts ()8 are connected to operate in unison by means of beveledpinions 80 at their rear ends engaging pinions 81 on a transverse rock shaft 82 jpurnaled in the frame 'of the machine. To actuate these shafts at the proper time one of the shafts (see Fig. 2) is provided with a pinion 83 engaging a segment 84 on a bellcrank lever 85 journaled on the frame of the machine and provided with a depending arm 86 carrying a cam roll engaging a cam 87 on the cam shaft 51.

The outer edges of the left-hand shoes and the right-hand shoes are similar in character, so that the slides 35 corresponding to these parts may be moved in unison. and for this reason the slide corresponding to the outer side of the left-hand jack is actuated moving in unison with the lever 48. The I inner edges of the two soles are also similar to each other but not to the outer edges. and therefore a single mechanism is used to ac tuate the slides corresponding to these edges. this mechanism operating, however, differently in point of time from the other slideactuating mechanism, as will be described.

As has been shown, the tool-changing mechanism operates at a fixed time in the cycle of operations of the machine forboth jacks and for both the inside and outside edges of the shoes. but, as is shown in Fig. 7, it is necessary that at such time the inside too-ls shall. ave advanced farther toward the toes than the outside tools, owingto the greater length of the inside of the shank, so that it is necessary to provide means for varying the longitudinal movement of the several tools during the operation of the &

portion previous to the changing of the tools. Furthermore, in operating upon different styles of shoes it is necessary to make further adjustments, as the relative lengths of the shanks and foreparts differ in different styles. For these reasons the lever -18 is connected with its actuating cam 50 through an adjusting mechanism. The lever is provided with a curved slot 90 engaged by a slide block 91 which may be fixed in adjusted position therein. A link 92 is pivoted to the block 91 and at its rear end is connected with a bell-crank lever 93 pivoted at 9-1 upon an arm 95 loosely journaled upon a shaft 109 lixed in the frame of the machine and carrying a roll engaging the cam path 98 in the cam 50. At the upper end 100 of the arm 95 is pivoted a curved arm 99 provided with a T-slot engaged by a slide block 101 which may be fixed in adjusted position therein. A link 102 connects this slide block v. ith a lateral arm 103 on the bell crank lever 93. A pin 10 1 projecting laterally from the forward end of the arm 99 engages a curved slot in a cam plate 105 fixed to the frame of the machine. It will be seen that when the arm 95 moves rearwardly under i the influence of the cam path 98 in the cam 50 it carries the arm 99 with it. .The bell crank lever 93 tends to rotate to the left and leave the lever 48 unmoved. but this tendency is resisted by the link 102 and the arm 99, and the latter is prevented from swinging upward by its connection with the cam plate 105, and thus when the arm 95 swings back the arm 18 is also swung back, with a motion modified in accordance with the form of the cam plate 105. acting through the connections described. The cam plate is provided with a slot having two portions 106 and 107, the portion 100 being traversed by the pin 101 prior to the exchangingof the shank and forepart tools. while the portion 107 is traversed thereafter. The shape of the portion 107 such that it causes no movement of the arm 99 with respect to the arm 95, and the arm 99 is so curved with i respect to the link 102 in the bell crank lever that whatever the adjustment of the slide block 101 maybe. the movement of the lever j 48 is not affected by this mechanism after 1 the tools have been exchanged. The portion l 106 of the cam path does. however. modify 2 the movement of the lever 18. By moving the slide block 101 in the arm 99 the extent of this modification may be adjusted. and in this way the mechanism may be so arranged t that within certain limits of variation the j shank tool may be adjusted to attain any desired position upon the sole edge at the time l of exchange of the tools. The curved slot 90 and the slide block 91 afford provision for varying the amplitude of movement as a whole of the lever 48, to

j comprising a link adjust the machine for shoes of difierent lengths.

The longitudinal movements of the inside tools are effected through a lever 110 loosely journaled on rock shaft -19 and actuated, through adjusting mechanism similar to that above described, by means of a cam path in the cam 87, and this arrangement permits of the independent adjustment necessary, as above pointed out, owing to the difference between the inside and. outside edges of the Soles.

The cam shaft 51 is set in motion automatically by ,the depression of the treadle by which the shoe is fixed in position on the jack. A worm-wheel 121 fixed to the cam shaftengages a worm-114 on a shaft 115 driven by a pulley 11G loosely journaled thereon. A clutch 117 operates to connect or disconnect-the pulley and the shaft, and is thrown into or out of operation by a rod 118 sliding longitudinally and provided with a bell-crank lever 126. A spring 119 engages brackets 120 in which the rod 118 slides, and tends normally to move the rod to the left (Fig. 1) to throw the clutch into engage ment. This is prevented, however, while the machine is out of operation by a lug.123 fixed to the worm-wheel'124 and engaging the upright arm 122 of the bell crank lever 120. thereby holding the lever and the rod 115" to the right. I The horizontal arm of the bell-crank lever is connected by a link 127 with an arm 12S fixed to a rock shaft 129 'carrying another arm 112 pivoted to the link 21. 'hen the treadle is depressed the arm 112, shaft 129 and arm 12S operate, through the link 127. to rock thebell-crank lever so that its upright arm 122 is disengaged from the lug 123. The spring 119 then operates to throw the clutch into engagement and the rotation of the wormwheel commences in the direction of the arrow. Fig. 1.

The forward extremity or toe of the sole is operated (Fig. 8). The toe tool has a rocking connection 1 32 with a depending arm 133 piv' oted at 134 in a yoke 135. The yoke 135 has horizontal arms 130 and 137 loosely journaled upon a vertical shaft 138. The shaft 138 is journaled in the arm 18 and an arm 139 on the frame of the machine. The toe tool has rapid oscillations of small amplitude imparted to it by means of connections 110 connecting the yoke 135 with a bell-crank lever 111, pivoted at 112 in a yoke having horizontal arms 143 pivoted upon the shaft 138. The bell cranklever 111 is pivoted at 14:5 to an eccentric strap 146 engaging an eccentric on the shaft 138. A pulley 1 18 fixed on the shaft rotates it constantly athigh speed, thereby actuatthe bell crank lever and one of the.

upon by a separate tool 12-31 ng. aneecentriqfland, through the connections above described, imparting a rapid vibratiomto' the toe tool. vibration it. is necessary to swing the yoke 135 througha considerable arc to cause the too-tool to vv'ork all around-the toe, and for this purpose a gear segment 150 is fixed to the arm- 143 and engages araek bar 151 slidingrhorizontally in-the frame of the machine. Therack. bar (see Fig. 2) engages a gear segment 152 on a lever 153 pivoted in the Y frame of the machine, and provided with-a cam rollengaging a cam path in-a cam 154 mounted on a shaft 155 journaled on the frame of the machine. The shaft 155 is connected by asprocket chain 156 with the cam shaft 51 so as-to-rotate in unison therewith. The cam ath is so formed that the toe tools, starting fromtheir' left-hand position, as shown in Fig. 2, are swung to a corresponding right-hand position while the s ank andifo art tools are advancing toward the toe, so that the toe is burnished or.

set at the same time as the side edges of the sole. During. its operation the toe tool is held in contact with the sole edge by means of a spring 157 engaging the arm 133 and a rod 158 passing loosely therethrough and fixed in a depending lug on the arm 137.

It is necessary to remove the toe tool from the soleedge before the forepart tools reach the toe, to-afl'ord'room for the latter to opcrate, and for this purpose each of the depending arms 133 is provided with a horizontalarm 159 in position to be engaged by the curved extremity 160 of a lever 161 fixed to a rock shaft 162 journaled in the frame of the machine. The rock shaft 162 has an arm163 provided with a cam roll engaging a cam path 164 in the cam 154 (see Figs. 1 and 2). At the proper time in the operation of the machine the arc-shaped members 160 are raised, thereby engaging and lifting the arms 159 and swinging the toe tools away from. the sole. This position is maintained by the toe-tools until another shoe is inserted in the machine and its operation is resumed.

The machine above described is capable of operating uponshoes of all sizes and styles with slight adjustments which may be readily made by the operator, and by the use of shank tools and forepart tools, with automatic means for exchanging them at the proper time in the operation of the machine, the machine is adapted to produce exact equivalents of the results produced at Work from one tool to another.

In addition to this i of the operator to remove and replace the Work.
