' HEEL-ATTACHING MACHINE Filed A ril 16, 1942 I 2 Sheds-Sheet 2 Patented Sept. 28, 1943 UNITED STAT as PATENT oFi 1,C Ei i 13 Claims.

This invention relates to heel-attaching ma chines equipped to operate upon shoes which are without counters and quarter portions and are commonly known as mules. It is an object of the present invention to equip the heel-attaching machine disclosed in United States, Letters Patent No. 2,178,615, granted November 7, 1939, on an application filed in the names of John F. Standish and Lester S. Macd-onald, for operating upon mule work.

The illustrative machine is provided with gages for locating the heel end of the sole of the mule and the heel which is to be attached to the mule in predetermined positions upon the jack of the machine. The gages normally lie in the path of movement of the loader block of the'machine and are slidin-gly, lowered as a unit in response to movement of the loader block so that fastenings carriedby the block may, without interference, be delivered to the jack. In. order to changethe relation of the work to points of insertion of the fastenings into the work, the sole and heel gages areadjustable as a unit heightwise and lengthwise of a shoemounted upon the jack, the heel gages being individually adjustable with relation to the sole gages in converging paths toward and away from the central portion of the work-supporting faceof the jack, 7

Preparatory to operating upon regular work,

in which the rear end of a top plate of the jack is engaged by a shoe counter to position the shoe upon the jack, it is desirable to remove the abovementioned gages to idle positions away from the jack. Accordingly, the gages of theillustrative machine, after being unlatched from their operative positions just rearward of the jack, may be swung laterally as a unit to idle positions at one side of the jack and may be latched in such positions.

Although the above work-poslti0ning mechanism is described as embodied in the above-mentioned Letters Patent No. 2,178,615, it will be understood that such mechanism may be used advantageously in other heel-attaching machines. A

Fig. 3 is a plan-view of the machine on line; III-Il-I- of Fig. 1, theheel holddown and otherparts of the machine having been omitted; and Fig. 4 is a section on line IV-IV of Figi 3.

The illustrative machine is described with reference to the attachment of a heel Zil'to a shoe or muleZZ (Fig. 1) and includes gages 24, 26 for positioning, respectively, the heel" end of a sole 28 of the mule and the heel '20 which is to be received by the mule, with reference" to atop plate 30 of a jack or work support 32, and a carrier 34, for the gages. The machine, with the exception of mechanism for supporting and' Operating the gages 24, 26, as will appear later, may be identical with the heel-attaching machine disclosed in the above-mentioned Patent No. 2,178,615. The illustrative Work-positioning mechanism is similar in many respects to corresponding mechanism which is disclosed in United States LettersPfatent No. 2,059,331, granted November 3,1936, on an application filedin the name of George W. Freeman, and which, because of limitations of space and'other considerations; cannot be used advantageously in connection with the improved heel-attaching machine disclosedin Patent No; 2,178,615. l

The jack 32 comprises a steel forging 36 (Figs: 1 andZ) into which are threaded a plurality of driver tubes 38 (Fig. 1) constructedand arranged to receive drivers 40. I When the machine is opcrating on regular worh the shoe is positioned upon the jack 32 by contact of the inside counter portion of the shoe with the top, plate 38 of the jack. It will be appreciated that, since -mules 22 have no counters, it isdesirable to provide the gages 24, 26 for positioning such workin the machine. 1 v Mounted upon the frame 42 (Figs. 1 and 2) of the jheeler is a casing 44 for supportin'gmechanism which guides. a nail loader block as from its nail receiving position, shown in Fig. 1, to a naildelivering position above the jack and back to its receivingposition. Nails 48 (Fig. 1) drop with their heads upward through nail tubesbli and, a fter passing through registering openings 41 in afoot plate 49, drop into pockets 5! of the loader block, a shutter 52, slidingly. mounted on the blockat this time having its" openings 53 registering with the openings 47 in the foot plate and the pockets 51- of the block. As the nail loader block lfi'i's reciprocated, together-with a slide, 55 (Fig. 3) lengthwise of guideways 54 (Fig. ),.formd inthe' casing, it is rotated with referenceto the slide upon trun'nions 56, with the result that the block at the forward end of its H stroke isfposi'tioned upside down above the top plate 30-of the jack 32, its openings 53' register ing with openings 58 (Fig. 1) in the driver tubes 38. Just before the loader block 45 arrives at the forward end of its stroke, the shutter 52 is slid with reference to the block by the engagement of a screw 50, which is carried by the shutter. with the top plate 38, thereby enabling the nails to drop, heads downward, into the tubes 38 of the jack.

After positioning the rear end of the sole 28 for supporting them and for actuating and retaining them inactive, is identical with the machine disclosed in Patent No. 2,178,615, no further description herein of the machine is deemed to be necessary.

Secured by a screw 10 and a dowel pin H to the left vertical guide 64 is abracket 12 a depending portion of which has alined bores 14 (Fig. 2). Mounted for sliding movement in the bores 14 is a vertical pin 16 having secured to it by a dowel pin 18 the carrier 34 which, together with the pin 16, is constantly urged upward by a spring 80, upward movement of the pin and the carrier being limited by the engagement of the carrier with the bracket 12, which serves as a stop. When the machine is operating upon mule work, the

carrier 34 is held against swinging movement about an axis 82 (Fig. 2) of the vertical pin 1'6 by a latch pin 84 which is secured to thecarrier and fits in a bore 86 of the bracket 12.

The carrier 34 includes a terminal portion 88 which is provided with a tongue 81 (Fig. 3) which fits in a vertical groove 89 of a guide portion 90 of the carrier and is adjustable along the groove through the provision of a slot-and-screw connection 92. a groove 9| (Figs. 2 and 3) registering with a horizontal tongue 93 (Fig. 2) formed in the intermediate portion 88 of the carrier, the gage being adjustable in directions 94 extending forwardly and rearwardly of the machine with reference to the terminal portion 88 of the carrier through the provision of a slot-and-screw connection 96 (Fig. 3).

The sole gage 24, which may be referred to as a fork, has work-engaging faces 98 (Figs. 2 and 4) and is preferably made in one piece and has its central axis Hi!) (Fig. 3) in alinement with the heightwise median plane of the top plate 39 of the jack. The heel gages 25 have upstanding work-engaging flanges 102 (Figs. 3 and 4) which are engaged by the rim of the attaching face of the heel 20, and shanks which fit in guideways Hi4 (Fig. 3) formed in the sole ease. The gages 26 may be secured in different adjusted positions in the guideways U24 through the provision of screws 136 which are threaded into the sole gage and pass through elongated slots I38 (Fig. 4) in the shanks of the heel gages. The heel gages 26, accordingly, may be described as-being adjustable with relation to the sole fork or gage 24 toward and away from the central portion of the workreceiving face of the top plate 30 of the jack 32.

It will be appreciated that when the gages 24, 28 are in their raised operative positions, shown in Fig. 1, they liein the path in which the loader The sole gage 24 is provided with block 46 travels during its nail delivering operation. Consequently, during the operation of the machine it is desirable temporarily to move the gages out of said path and, with this in view. the gage carrier 34 has secured to it by screws Hfi a bar or cam H2 having an upper cam surface H4 which, during the forward movement of :the loader block 46, is engaged by a cam roll l is mounted upon the loader block slide 55. The carrier 34 is therefore depressed, together with the vertical pin (6, against the action of the spring 80, it being prevented from turning about the axis 82 of the pin during such movement by the engagement of the latch pin 84 in the bore 86 of the bracket 12.

Preparatory to operating upon shoes having counters (not shown), it is desirable to move the gages 24, 26 to idle positions away from the top plate 33, since the top plate itself, by reason of its engagement with the inside of the counter portion of the shoe, is used to position the work in the machine. Accordingly, the carrier 34, when in its operative position shown in Figs. 1, 2 and 3, may be depressed against the action of the spring 88 and swung outwardly. that is, rearwardly and to the left, as viewed in Fig. 2, about the axis 32 of the pin 16 until the latch pin 84 lies beneath a bore 1 IS in the bracket 12. Downward pressure against the carrier 34 is then released to permit the carrier to be raised by the spring 88, the pin 84 entering the bore and positively holding the carrier, together with the cam I l2 and the gages 24, 26, in its idle position away from the operative parts of the machine.

Although the invention has been described with reference to mules, it will be understood that the above-disclosed work-positioning mechanism may be used effectively in connection with the attachment of heels to open-back sandals.
