HEEL-SEL'EFITTING MACHINE.

Agplicgitipn filed September 14, 1915 To (6 whom. it may (:rmeprn:

l e it known that we, SAMpmii J. VVE T- won'ru and Fimnuniou H. PEin Y citizens of the United States, residing at Newport, in the county of Campbell and State of Kentucky, and Beverly, in the county of Essex and State of hidSSwC-llllSQltS, respectively, have invented certain improvements in l eelHeat-l itting ltlachines of which the following description, in connection with the :n'roinpanying drawings. is a speciiiew lion. like reference charaulcrs on the drawings indicating like parts in the several figures.

This invention relates to machines for operating upon boots and shoes and is herein illustrated in connection with a machine for forming upon the heel portion of the sole of a shoe a convex heel seat to fit into the concavity of the heel which is to be attached.

In the manufacture of shoes it is cus ternary to attach the rough heel and then to trim the heel and the edge of the heel porlion of the sole simultaneously, and later to scour and hurnish them. ithwooden heels, howeveh this procedure is not practicable Since to trim a wooden heel and the edge of a leather sole simultaneously in a. satisfactoi'y manner would be difficult. Moreover a wooden heel is con'nnonly covered With a thin veneer of leather or celluloid which cannot be subjected to the scouring operation without injury. Accordingly Wooden heel is completely finished before being attached; and the edge of the heel portion of the shoe is trimmed ofi so as to permit the upper edge of the heel to extend close to thenpper of the shoe. A Wooden heel has a concavity in its upper face; and the trimmin of the heel portion of the sole is such as o provide a raised seat to receive this concavity, the forward end of the seat terminating in a shoulder ngainst. which the upper forvv lrd of the heel may abut.

The general object of the present invention is to produce an improved machine for removing stock from the heel portion of the sole of a shoe prior to the heel attechln oration to provide a seat for concavity ofa heel; and the illustrative is an improvement upon the machine shown in the Specification of Letters Patent.

eiplication of S. J. iVentworth Serial No. 8 5,468.

An important feeture of the invention relates to the provision in a mix-chine of the class described of means for producing an Lnidcrcut shoulder at the end of the heel scat. lYooden heels are commonly of the Louis type having projecting lips at their upper forward ends. in order to make a smooth joint at the junrtipn oi' the breast of such a heel with the shank oi the sole the project inn upper forward portion of the heel is in seried beneath the undercut shoulder.

l his and other features of the invention, including certain details of consli'lnrtion and combinations of parts, will he described as embodied in an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying dra wn r Figure 1 is a side elevation of a machine in which the present invention is embodied:

Fig. 2 is a perspective of the upper po tion of the machine;

Fig. 3 is a. perspective of the heel portion of a shoe the sole of which has been operated upon by the machine;

Fig. 4 is a perspective showing more porticulnrly the mechanism for adjusting the position and for opening the jaws which support the shoe;

Hi 5 is a. plan of the supporting jaws and the mechanisms for adjusting and operi g them- Mounted in horizontal Ways in the frame 1 of the machine is a. slide 3 having a horizontally projecting portion to which the trimming knife 5 is fastened. The presser roll 7 is carried by an arm 9 the forked rear end of which is pivoted upop a swinging stud 11 suspended by a link 13 from a stud 15 which is carried by the slide 3. Passing through the forward portion of the arm 9 is a pin 17 suspended from a second pin 18 i by links 19, Said Second pin also passing through the forward end of a two-part. lever 21, 23. Both parts of this lever are pivoted about a stud 25 carried by the slide 3, a projection 123 on the lever 28 being itl'lfiflged to contact nornurlly with a pro em on 1 21 on the lever 21, the two parts hemg held in the position shown by a heavy tlat. resi ent ba 2? the tension of which may be adjusted by means of a thumb screw 29 which passes through the part 23 and contacts with said bar.

In the operation of the machine, after the shoe is in place. the first operation is to bring the presser roll 7 down upon the sole of the shoe. This is effected in the following manner:----'l oggle links 3 and 35 are pivoted respectively upon a pin 37 carried by the part. J3 and upon a pin tit) carried by the slide H. An arm 4]. which is normally held in the position shown by a spring 42 is provided with st llds -13. 15 carrying rolls 47 and 45 said arm being fast to or a part of the hub of the toggle link 3:"). When the maehine is started the end of an arm 51 is brought down upon the roll 47 thereby swinging the arm -"ll downwardly and straightenin; the toggle to cause the presser roll to be forced down upon the sole ol the shoe through the resilient bar 27. .\t the wine time the roll 45 enters the open end (ii an u invardly inclined track 53 the angular position of which may be varied after the clamping bolt 55 has been loosened. liy adjusting the angular position of the track o l the descent of the roll 7 may be controlled. In other words the roll may be caused to depress the sole more at one point than at another.

inasmuch as the presser roll 7 must :11 ways he. brought down upon the sole of the shoe. at a point just forward of the curved base of the jaws which support. the edge of the sole while the stroke of the knife. must be long enough to take care of any length of heel seat and consequently of any horizontal position to which the roll 7 may be adjusted, the knife is caused to start its horizontal motion before that of the roll 7 and to pick up and carry along the roll when the forward edge of the knife has reached a posi tion close to the lowermost point of said roll. \Vith the construction of the parts thus far described if forward movement is imparted to the slide 3 no forward II'lOVGITlBIlt will at first be lll'lIJHllIQd t0 the roll 7 since the link 13 will merely swing about the stud 11. Forward movementof the roll is brought. about by a. pull exerted upon the stud 11 by a link 57. said link being pivoted at its forward end to upstanding ears of a slide 59 mounted in suitable ways in the horizontal projection of the slide 3. This slide 59 carries a box 61 in which is a transversely slid-able latch 63 the ends of which project angularly toward the rear of the machine as shown. The outer end of this latch normally lies in an angularly disposed socket 64 in a part 65 which is stationary during the operation of the machine but is slidable in the frame and may be adjusted horizontally to provide for di'tl'ercnt lengths of heel seats as will presentl be described. The inner end of the latel is adapted to be received and drawn into a socket (57 formed in apart of the slide 3. The rear walls of these two sockets project toward each other, that is toward the center of the slide 59, more than do the tor ward walls; consequently when the slide I3 is moved forward the projecting portion ol' the. r ear wall of the socket (37 draws the latch till out. of the socket (34 and into the socket ti? whereupon, as the slide 3 moves t'arther forward, a pull is exerted upon the link 57 to cause the roll 7 to travel forward in unison with the trimming knife 5. ()n the return movement of the slide 3 the outer corner of the latch 03 is caught by the projcrting wall of the socket (ii and drawn into said socket so that when the one-rcvolution clutch, prcscnt ly to be referred to, brings the machine to rest. the parts will be in the position shown. The arm 5! is operated by means ot' an up right rod tii' troll] a ram Tl mounted on the dri\ ing shall 72 llcierring now more. particularly to Figs. :1 and 5 the construction, operation and ad justmeut ol' the jaws T5 which support the projecting heel portion of the sole will be described. These jaws are pivoted at 77 on the member 65 which, as has been stated, is a slide member and may be adjusted horizontally. One of the jaws 75 has a tail 7t) to which is pivoted a rod 81, said rod being uintained in a socket 165 which is integral with the slide (35. A spring 83 surrounds a reduced portion of the rod and may be compressed desired by turning a threaded sleeve 85. A nut 87 on the end of the rod 81 holds the parts in the position shown and determines the normal distance between the two jaws 75. The rear portion of the jaws near the. pivots 77 are provided with intermeshing teeth 89 to insure. that the angular movement of the jaws shall always be equal and in opposite directions. In order to open the jaws preparatory to placing a shoe in position, an arm 91 having an elongated flat operating face 93 is carried by two parallelmotion arms 95, the hub of the ri ht hand arm being connected with a rod 9 to the lower end of which is attached a treadle 99. The operating face of the arm 91 is elongated because, as has been explained, the member 65 by which the jaws are carried is horizontally adjustable. This horizontal adj ustment is accomplished through a roll 101 *arried on the under side of the slide 65, said roll extending into the track of a barrel cam 103 pivoted at 105 to the frame of the machine. Integral with the hub of the barrel cam is an arm 107 carrying at its outer end a spring pressed pin 109 which is fast to a knurled handle 111, said pin being adapted to register with any one of a plurality of sockets 113 in a scale torined on the frame of t e mach ne- The s chat may b un:- bered in any suitable manner as shown n Fig. 2 to facilitate loenting the pnsitlou of the Slide 65.

When the shoe is brought to tho present ac i t eomm nly ontains no le t and is placed upon the jack 115, said junk being pivoted at its lower end to the frame of the marhine and being adapted to be held in the position shown in Fig. 2, by means of puwls 117 which are fast to a rod 11-9 and noiipepate h a r nk 12 alieudle 1:25 prov dml to lif tin; p ls when it is desired to swi g h ja k mto the min m shown in Big 1, he pper serious o the jack him m the position shown in F lg .2 somew at below the under su-rffioe of the t in jaws 75 so tha the roll 7 may depre s t e middle of h h e Po on of the sale n order, howe t h ld the shoe up s that the jaws will properly nt r the sl-ease between the solo and the upper when the is moved from the position shown in Fig. l to that shown i F g- 2 a spr ng pressed pin .12 is mounted near the real end of the junk,

The ti.-'imming knife 5 forms upon the heel portion of the sole a horseshoe-shew and which is removed by the knives mounted in an eppyoximately vertical slide 131. This slide is mounted in a guide member pivoted to the frame of the machine about time stud 13'5 end adopted to be held in adjusted angular position by means of a pin 137 which may be put through any one of a series of holes 139 in a flat plate fanning a portion of the frame of the machine and into a socket in the guide member 133. The axis of the stud 1:35 lies in the path of movement of the trimming knife so that the lowermost positions of the of the slitting-off knife will be substantially the same irrespective of the angles of inclination of the guide member 133. The slide 131 has a. projeeting arm provided with a vertieal slot 141 to receive a bolt 143 by which the knife holder 145 is attached to said arm, an adjusting screw 147 being provided to move the knife holder up and down when thebolt 145 has been loosened; The holder 145 has a h0rizontal flange or shelf 245 provided with u downwardly extending pin upon which are hinged the adjacent sides of two blade holders 149 oaeh blade bolder being connected by a link 1551 with a stud 158, said Stud being adapted to be clamped in adjusted position in a slot in said shelifi-lfi. By moving the stud 153 the angles which the planes of the blades make to each other may be varied.

Inasmuch as the blades 155 have to produce cuts the bases of which slope upwardly as shown in. Fig.8, said blades are fastened to their holders by means of bolts 157 whieh pass through .wmpamtlvqiy huge holes in Said kni es and are threaded into said holdem The pu pose of adjusting the blades 15 in 8 lml'ifloflwl path about the pivot of in: nge is to pmduse a curved out m-ross film sols oi the shoe, At the time the blades not the heel portion of the sole is distorted y bw'il g lls middle portion depressed with respect to it edges. With the sole thus held t ou made by a straight edged knife at an angle of more or loss than ninety degrees to the axis of cnryutiu'e of the sole will in suit in u clu'lfid out when the sole resumes its normal tint shate. W'ith some heels such it flfll'vtd out is (lnsilablo. When a straight hit is desk-ml the edges of the blades are brought into line in a plane which intersects he H s 0f rmi'ature of the sale at right angles, It should be noted that angular ud jnstment of the guide member about the axis of the stud 135 permits the angle of the face of the shoulder at the forward end of the heel Soul to be varied. In F ig. 3, the face of this shoulder is shown us vertical, but in many instances muuufurturers prefer that it hould be iuelinol and particularly that it should be inclined upwardly to the rear oi the shot So ES to produce an undercut shoulder beneath which the upper, forward, projo ting end of the heel may be inserted.

The slides 3 and 131 are reeiprocated as follows: Fast to the Slide 3 is a rack 15%) which meshes with a pinion 161 rotatable upon fined benriugs. A vertically disposal n l; L63, which meshes with this pinion, is pivoted ul; 1137 to a rod 169 the lower end of which is pivoted at 171 to :1 lever 173 the other and of said lever being pivoted at 175 to the frame of the muohine. A roll 177, carried by said lever, runs in av cum track '79.- Turning now to the slide 131, said slide is pivoted to a rod 181, the lower end Of which is pivoted at 183 to a lover 185, the other end of which is mounted on the pibcot 175. A roll 18? carried by said lever {nuns in a cam track 189, The shaft 78, to which the cam member is fast, is actuated from a suitable source of power through a one-involution clutch (not shown) when a treudle 191 is depressed. The lever 51, as has been explained, is operated from a roll on the lower end of the rod 69 which runs on a cam 71; and all the cams which have been referred to are formed in a memher which is fast to the shaft 73.

The operation of the machine is as follows:

The handle 111 is manipulated to adjust the jaws 75 longitudinally in aroordnnre with the length of the heel seat which is to be formed; and the blades 155 properly adjust/ed in both their horizontal and vertical paths. The shoe to be operated upon having been placed upon the jock 115 and the jaws 76 ofielid"hy*dopfislflg tl'l tielldl 99", the

jack is swung forward from the position shown in Fig. 1 to that shown in Fig. 2, the pawls 117 cooperating with the rack 125 to hold the jack from swinging back. The treadle 9!) is then released whereupon the jaws move into supporting position bencath the projecting heel portion of the sole of the shoe. The treadle 191 is then de-- pressed to cause the shaft 73 to make one revolution. Upward movement of therod (i9 straightens the toggle 35, 37 to bringthe presser roll 7 down upon the middle of the heel end of the sole; downward movement of the rod 169 moves the slide 3 together with the knife 5 forward, and presently, the latch (33 causes the roll 7 to be moved in unison with the knife. This movement in unison of the knife and roll causes the formation on the heel portion of the sole of a horseshoe-shaped tongue which is removed by the descent of the chopping knife due to a downward pull by the rod 181. All of these movements take place during a portion of a revolution of the shaft 73; the completion of the revolution returns the power actuated parts to their normal position which is the one shown in Fig. 1. The operator then manipulates the handle 12? to release the jack, after which he swings the jack to the position shown in Fig. 1 removes the first shoe and places another upon the jack.

The cavity in the top of the heel which is to be attached generally presents a true concave surface, but the surface of the heel seat is not necessarily truly convex. The terms concave and convex, however, have been used to promote brevity since these terms define the formations with sufficient clearness and since it is obviously immaterial whether the surfaces referred to are truly convex and concave. By referring to Fig. 3 it will be seen that the heel seat extends on an incline from substantially the line of junction of the upper with the sole to a line considerably inside said line of junction.

The invention has been illustrated and described as embodied in a machine which shapes the heel portion of a sole to receive the usual concavity in the top ofa wooden heel, but it should be understood that this has been done to promote brevity and that the invention in its broader aspects is not limited to the particular form of heel seat which has been shown and described.

Although the invention has been set forth in connection with a particular machine, it should be understood that the invention is not limited in the scope of its application to the )articular machine shown and described. I aving thus described our invention,
