LINING-TRIMMING MACHINE.

In the manufacture of certain kinds of fancy shoes, it is customary to die out ornamental openings in the upper, to attach the lining to the upper by stitches which extend along the edges of these openings, and later to cut out those portions of the lining which are exposed by the died-out openings in the upper. The portions of the lining which are thus exposed are commonly called panels,- and the operation ofcutting them out as panel cutting. p

- his panel cutting may be done in the stitching-room before the lined upper has been attached to the sole or insole and while it, or portions of it, may be spread out substantially flat; but preferably the cutting I cutting block has a curved shearmg edge the is done in the packing-room after the shoe is otherwise complete, since, if the cutting is done in the stitching-room, the subsequent stretching of the upper during the pulllngover and lasting operations is liable to distort the ornamental openings.

Hitherto the cutting of panels from otherwise finished shoes has been performed almost entirely by hand, although a few machines have gone into use which are capable' of cutting out panels in the more readily accessible portions of the upper, such as the side portions. Many shoes, however, have panels so located Qf or example in'the'toe portion of the'upper) that it is impossible with machines heretofore known to cut them out. v

The general object of the present invention is to provide a machine for performing this and similar operations upon any locality of the shoe upper.

One obstacle which has heretofore prevented, the cutting out of panels not readily accessible has been that the worksupport, as Well as the arm or other member by which it has been carried, has been stationary so that the shoe could be turned in one direction or the other during the cutting operation only. until such turning movement was arrested by contact of some'part of the upper of the shoe with the work support or carrier.

' According to one feature of the present invention, the'carrier for the cutting block or illustrated is of a general U-shape, its arms being substantially horizontal and; located one above the other, the cutting block being carried at the extremity of one of the arms.

With such a construction, ashoe having a panel not readily accessible, such as one in the toe portion, may be placed over the arm with the cutting block in position to support the panel from the inside of the shoe; and then the shoe may be moved over the arm and turned in one direction or the other with the arm, and both may be turned completely around if desired.

In machines of this kind, it is desirable that a shearing out be employed. According to another feature of the invention, the

curvature of whichis concentric relatively to the axis about which the carrier swings. The cutting block and its shearing edge are preferably annular to provide for the maintenance of a cooperative shearing relation with the cutter irrespective of howfar the cutting block is turned about its axis. As

illustrated, the cutter is operated by reciprocation lengthwise of said axis and its outting edge is curved to conform to the inner edge of'the annular shear member with'which it cooperates. 1 A relatively slender pilot portion formed on the cutter projects in advance of its cutting edge to pierce the work prior to the trimming operation and to maintain continual contactbetween the cutter and the I inner edge of the annular shear member during the trimming operation. This continual contact insures guiding the cutting edge of the cutter in the desired cooperative. relation to the annular shear member irrespective of rotary motion of thelatter and irrespective of any stress tending to deflect the cutter laterally out of register with the annular member.

These and other features of the invention, including certain details of construction and combinations of parts, will be described as em.- bodied in an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying draw- I t Figure 1 is a perspective of a machine in which the present invention is embodied;

Figure 7 is a perspective on an enlar ed scale of the combined cutter guard and edge gage. I y

. Referring first to Figures 4, 5 and 6, the general mode of operation of the machine will be briefly described. The machine comprises a reciprocating cutter 9 having a pointed pilot portion 11 and a narrow cutting edge 13 ,at one face of the cutterwhich is curved, as shown in Figure 6, to conform to the curvature of the inner wall of an annular shear member 15 or cutting block arranged to support the work. A combined cutter guard and edge gage 17 has a curved face which is in contact with a curved face of the cutter, a depending lip 21 which acts as a gage, and a flange 23 which is located in front of the cutter to prevent injury to the fingers of the operator. The cutting block or shear member 15 is carried by one end of a substantially horizontal arm 25 which is rotatable about a vertical axis coincident with the center of curvature of the shear member. With this construction it will be clear that the coo erative cutting relation of the cutter and t e shear member will be may be swung.

Referring now more particularly to Figure 5, there 1s shown a portion 100- of the upper of a shoe having an ornamental opening 200 therein across which extends the lining 300, the upper and lining being fastened together alon the edge of the opening by a row of stitc es 400.

In the operation of the machine, the cutter 9 and guard 17 are first raised manually to permit a shoe to be placed over the arm 25 with the shear member 15 supporting the desired locality of the shoe from the inside thereof. The cutter and guard are then lowered manually to the positions shown in Fig ure 5, the pointed portion of the cutter, during this descent, acting to pierce the panel so as to start the cut. Immediately upon the completion of this descent the automatic reciprocation of the cutter begins, but the pilot portion 11 remains in contact with the shear member 15 throughout the range of automatic reciprocation to insure accurate cooperation of the cutting edge 13 and the member 15. The shoe is then fed by the operator in such manneras to cause that portion of the lining which extends across the ornamental opening 200 in the upper 100 to be cut out progressively. During this feeding the shoe may be moved as desired with respect to the supporting arm and may be swung to any desired extentcompletely around if necessaryby reason of the mounting of the arm. It is thus possible to cut out panels irrespective of. their outlines and locations.

The cutter 94s fastened to a block 29 by.

screws 27 i i-"such manner that the cutter may be adjusted vertically; and the block is in turn fastened by a screw 31 to the lower end of a cutter-bar 33 in such manner that it may be adjustably "laterally. The cutter-bar is vertically slidable in alined bearings formed with the outer end of an arm 47, the inner end of said arm being loosely pivoted on a stud 49. Also loosely pivoted on the stud 49 is the inner end of a second arm 51, the outer end of which is pivoted at 53 to a short link 55 the lower end of which has an openin to receive a crank-pin 57 onthe end of a driving shaft59, a ball-bearing 61 being located between the crank-pin and the link 55. When, therefore, the shaft 59 is rotated, the arm 51 is swung up and down about the stud 49. In order to transmit this movement, when desired, to the arm 47 and thence to the cutter 9, as well as to permit the cutter to be raised at. any time and brought to rest in raised position, the lower arm 47 has,a lug 62 with the under face of' which the upper face of a lug 63 formed at the lower end of a depending portion of the upper arm 51 is adapted to contact. A spring 65 coiled about the stud- 49 has one of its free ends engaging the under side of the upper arm 51 and the other free end enga ing the upper side of'the lower arm 47. T is spring thus tends at all times to swing the arms apart cause reciprocation of the cutter-bar 33, a

latch 67 pivoted at 6910 the lower arm extends beneath the lug 63 of the upper arm, said latch being urged at all times to swing in a clockwise direction by a spring 71 which extends from beneath the lower arm 47, around the pilot 69 and up over the tail of the latch. When, now, the shaft 59 is rotated, the upper arm 51 is-oscillated about the stud 49, and the same oscillation is imparted to the lower arm 47, since the arms are positively held from angular movement with respect to each other. The outer end of the lower arm is connected with the cutter-bar .in the manfier'which has been described,

and consequently the cutter is reciprocated. In order to provide for tripping. the latch and raisingthe arm 47 when desired, and thus raising the cutter and bringing it to rest, a

,rod 73 slidable in verticallyalined bearings has its upper end located beneath the tail of the latch and has extending from-one sidethereof and beneath the lower arm 47 a pin 75.

When, therefore, the rod 73 is pushed upwardly, its upper end first disengages thelatch andthen the pin 75 raises the arm 47 against the force of'the spring 65. cutter is thus disconnected frpm'its driving mechanism and held raised well above the worksupport. The cutter .is thus raised and brought to rest wh enever' it is desired to start the cutting out of a panel, the cutter being raised sufficiently to bring its pointed portion 11 well above the level of the work support so that the shoei'nay be moved tobringa fresh panel into place to be pierced by said pointed portion whenthe cutter'makes its first downbe pierced.

ward. movement. This downward movement occurs as soon as the rod 731s per- I mitted todescend. At that time the spring swings the lower arm l7 downwardly as far as the

lugs

61, 63 will permit; and the spring 71 causes the latch '67 to engage once more the under side of the lug 63. .The

arms

47, 51 are thus once more held from angular movement with respect to each other and the cutter is reciprocated. If desired, atensionspring 77 may be connected at its upper end to the lower arm 47 and at its lower end to the head of the machine to supplement the action of the spring 65. Such additional spring is particularly advantageous when a panel composed of thick, tough leather is to v The rod 73 is raised, for the purpose which has, just been described, by means of a lever 79 pivoted at 81 to the overhanging arm 37 and having pivoted to its outer end a treadle rod 83 to the lower end of. which. a treadle (not shown) is connected. The operative end ofthe lever 79 carries-a screw-85 the head of and to the fin ers of the operatorf Referring 'more particularly to Fi which contacts with the under side of a pin 87 carried by the rod 73. A tension spring 88 connects the with the lever.

As has been 'brlefly explained, there "Is associated with't-hecutter a combined guard and gage, 17 having a depending lip-21 which engages the edge of the ornamental opening 'in the upper. Thiscombiaied member serves bothto "facilitate the guidingof the shoe and to prevent accidental injury both to the upper res 5, 6 and 7,-this j member has avertical aee21tojengag'e the edge of the opening in the upper, ahori-* zontal face 89 to rest upon the margin of the upper about the ornamental opening, and a flange 23 extending in front of the cutter.

The

shown best in'Fignre 5.

In order to hold it in that position and to permitit to be, raised independently of the cutter so as to pass readily over a relatively thick portion 700 of the lining, such as a seam, the rod 95 (Fig. 4) has fastened to its upper end a bar' 98 upon the upper side of which a spring-pressed plunger 99 bears,-

downward movementof the rod being limited by a stop-screw 101 which engages the under at 81 to the overhanging arm and connected at its inner end to the upper end ofasectional pull-rod 105, the lower end of which is pivoted to a bell-crank lever'107 pivoted side'of the bar 98. Also engaging the under. side of the bar 98 is a lifting lever 103 pivoted combined member occupies the position in turn at 109 to. a bracket 111 fast to the pedestal 39, said bell-crank lever being urged at all.times by a spring 110 to rotate in a clockwise direction as far as an adjustable stopscrew 113 will permit. Extending 'dowifwardly from the bell-crank lever-is a rod 115 to the lower end of-which is fastened a knee-piece 117 arranged to be moved by the knee. of the operator. An'adjustable sto screw 119 determines the extent to which t e bell-crank lever 107 may be rocked. 'The two sections of therod are adj ustably fastened together'by a clamp 1. 21. Durlng the cutting 1 operation, the lower edge of the lip 21 of the 1 I combined guard and gage 17 should be in contact with the lining 300; and when a seam such as that represented at 700 is about. to pass under the lip 21 itpassage will befacilitated by lifting the member 17 but the latter should not be raised so far as to isengage the lip 21 from the edge of the ornamental opening in the'upper. The stop-screw 101, which determines the lower limit ofmovement of the combined member, and the stop-screw 119, which determines its upper limit, may be adjusted accordingly. When a seam in the lining'is encountered,'therefore, the operator has merely to operate the knee 'lever mechanism in order to raise the combined guard and a e into the ro er osition. g is has been exglaiilbd above, the arm 25 is rotatable about an axis passing through the axis of curvatureof the shear member 15. In the illustrative machine, this shear member is detachably clamped in the arm 25, the latter being at the lower end 'and apart of a pendent, U -shaped work-support 125. The

arm'25is thus arranged to project into a holl'ow article of Work such as a shoe, and since all the rest of the work-support is above the level of the arm 25 a clear, unobstructed support 125\ but also. provides bearings" through which the cutter-bar 33 and the gage-rod 95 extend. If desired, the swivel lconnecticn between the work-support 12 and the boss 135 may include ball bearings 137 held intact by a nut 139 applied to the lower end of said boss.

. Since many cuttingstrokes of the cutter 9 are necessary to sever completely the panel of waste-material, and since the work must be fed meanwhile, it is desirable to fend the panel from entering the hole in the shear member 15. Accordingly a fender 141 is arranged in the hole of the member 15 so that its work-engaging surfaceuill lie substantially flush with the plane of the shearing edge of said member. The fender is smaller than the hole in the member 15 to provide a space into which the cutter 9 may enter, and is preferably mounted to exert pressure against the cutter, transversely of. the hole, to insure shearing relation of the cutter and the shear member 15. For these purposes the fender is formed .with a stem that extends loosely through a hole in a support 143 so that it may tip from side to side, and a compression spring 149 is arrangedo'n the'fstem .Iin substantially coaxial relation to the hole. -

Nuts

145 and 147 screwed on the stem cooperate with the spring to holdthe fender normally to produce the effects mentioned above. The

J support 143 is aflixed to the arm 25.

over the shear member 15'.

In operation, the point of the cutter 9, as it enters the hole in the shear member 15, deflects the fender laterally, and the reaction of 'the spring 149 maintains lateral pressureof the 'fender against the cutter. In the event that the point of the cutter fouls the'fen'der the spring permits the latter to yieldaxially to avoid breaking the cutter, and in thecourse of one or two strokes of the cutter the'fender is deflected and takes the position shown by Figs. 5 and 6.. The operation of the'cutt'er,

produces vibration of the fender which facilitates the passage of the -.wa'ste material Referring now to Figure 2,thei'eis shown a shoe having ornamental openings 'in'the.

Considering first the operation of the ma.- chine with respect to the, openin 500, the treadle (not shown) which is attadhed to the lower end of the treadle rod, 83, is depressed to raise the cutter 9, and with it the guard 17, Well above the cutting block 15, it being understood that the extent to which these members are raised is suflicient to permit the upper and lining of the shoe to pass beneath them as the shoe is slipped over the arm 25. The treadle is then released to cause the cutter and guard to descend to the positions shown .in Figure '5. .Thereafter the shoeis fed manually over the arm 25 in such manner as tocausc the lining to be cut out. When 0 a' seam such as that indicated at 700 is encountered, the kneelever 117 is manipulated tb raise the guard 17 slightly. It should be particularly noted that to trimentirely around an opening requires turning the shoe about a vertical axis through a range sometimes 360 degrees and that the rotary mounting of the carrier 125 provides for unlimited turning movement. The operation upon the lining beneath the openings 600 is like that 1 1- whieh has been described above except that in the first downward movement of the cutter, after the shoe is in place, the pointed portion 11 of the cutter pierces the panel.

b Although the invention has been set forth as embodied in a particular machine and in connection with, a certain kind of work, it should be understood that the inventionis not limited in the scope of its application to the particular machine, nor to operation upon the particular kind of work which has been shown and described.
