Brandt, Marblehead, Mass., assignor to United Shoe Machinery Corporation', Paterson, N. J., a corporation of New Jersey Application' August 10, 1937.; Serial-No. 158,415`r 19 Claims.

My invention relates to heel-attaching machines or tothose for. attaching heel-portions, it being particularlyconcerned with apparatus arrangedfor manual lactuation andadapted for use by repair men; v l

The invention has'as anobject the provision ofa machinezwhich is simple, inexpensive and convenient tofoperate.. In the attainmentof this object, thexfollowing features are improved: the

1D; manner ofarranging and actuating the worksupport, lespecially with reference to the yieldable mounting and retention uponV a plunger, Whichmay furnish the body of the support, of a top-portion, which constitutes the work-support 115? proper; the means for retaining the plunger in any position'to which it maybe moved by the operator, this' facilitating the making of adjustments in the heel-pressure mechanism co-operating with the support; the driver-assembly, par- 2U()` ticularly as 'to the'manner of 'giving access to it and the securing of drivers with inclined fasteningeengaging ends upon their plunger in predetermined angular positions about their axes; and the adjusting means for the work-pressure mech- 25 anism, both as to the abutment for the treadsurfacey of a'fheel and as to the rear abutment.

vOne of the several embodiments which myinvention may assume is illustrated in the accompanying drawings, in which vFig. 1 is aside elevation of my improved heelattaching machine, with portions in section;

Fig. 2, a sectional elevation of the elements more closely associated with the work, these being in'a diierent position from that appearing in Fig.k

35 1, tlll'lr Fig. 3, an enlarged horizontal section on the line III-III of Fig. 1.

'I'he character If' designates a frame, Which-is herein shown as of the type arranged to have its 4Q base secured to a bench and having an overhang arm I2'1curvedy rearwardly and then forwardly above the base. Mounted to move vertically through an opening in the base is a plunger I4 furnishing the body-portion of` a work- 45, support or jack. To receive its movement, the plunger is provided `at its forward side with a rack I6, withwhich meshes a pinion I8 fast upon a short horizontal shaft I9 journaled across 'the base. Secured to the shaft is a hand-lever 20 50. rising at one side of the frame-arm, arranged to begra'sped by the operator and swung in opposite directions to either raise or lower the plunger. To yieldably maintainthe plunger .at the point to which it maybe moved` by .the operator, there 55. acts upon it afriction device, shown as. compris-v (Cl. 1-32)L inga plug 2| sliding in a-horizontal bore in the frame.r Theplug is forced against the plunger by a spring;22 backed by a screw 23threaded into the outer endof the bore. Guided for vertical movementl about theplunger is an upper portion 24 which furnishes the work-supportl proper. This conforms generally to the counter-portion of a shoe, such as is shown at S, the insole thereof resting upon the upper surfaceof the member, positioned for the attaching operation. From the member 24 depends a sleeve-portion 26, which surrounds and isguided by the outside of the plunger. TheA rsupport-top 24.` is held normally raisedby a helical spring. 28fcontained' in a longitudinal passage 30 vin the plunger. At its `lower extremity, the spring abuts'against the plunger, while 'at-.its upper endit contacts with a sleeve 32 movable `freely in the passage. The expansion of the spring-,and the extent to which the sleeve may be elevated are limited by contact of the latter'withI ahead 34 formed on the upper extremity of a rod 36A which passes through them and is threaded into @the plunger at the bottom of the 4passage 30. The head 34 is slotted to receive: avscreW-driver, so the rod may be inserted and removed', and the parts readily assembled and disassembled. Therod and sleeve extend into a cylindrical recess 38 within the sleeve-portion 26, the top wallofthe recess resting upon the upper endV of the s1eeve32, with the rod-head 34 in a centralpassage 40 in the support-top 24.v The spring 28, through the sleevev 32, thus supports the -top.24 `to yield under pressure.

About .thepassage 40 inthe top are driver-passagesl 42, herein shown as five innumber. These 3 correspond inarrangement to the particular design in accordance with which nails N or other attaching fastenings are to` beinserted in the work. vWith their lower ends resting upon the uppery extremity of the plunger I4 and passing through the recess 38 into the passages 42 are drivers 44, one for each of said passages. The drivers are accurately positioned upon the plunger in vertical alinement with the passages by a locating plate 46, carried on the plunger and containing a setof ve openings 48 into which the driver-enlds nt. Preferably, the drivers have nail-engaging ends 5Il-which aredownwardly and inwardly inclined to holdthe nails with their enteringpoints toward the inner sides of the passages 42, so when driven, said nails will toe in. This reduces thefliability of emergence of the points through the side-wall of a heel H being attached. To insure the correct relation of these inclined endsabouttheaxes of the drivers and to hold. them against separation from the plunger, each driver has at its side just above the plate 4G, a slot 52, each slot being in a definite angular relation about the axis of the driver to the inclination of the driver-end. Resting upon the plate 46 is a polygonal plate 54 having an opening 55 to receive the sleeve 32, the plate being Yof such width that it will occupy the slots '52, as these are located just above the upper surface of the plate 46. The plate 54 has a side 56 corresponding to each driver, the angle between the sides being such that as the edges of the plates lie in the slots, they will so limit the rotation ofthe drivers-about their axes in the/openings 48 of the plate 46 that the inclined ends 50will be correctly positioned. To secure the two p-lates on the plunger, there passes through registering openings in them the shank of a screw 58. YThis screw is threaded into the top of the plunger I4 and holds the plates and the drivers in the desired relation, also securing'them to the plunger. An elongated cylindrical head 59 of the screw extends intoa passage in the top 24, so the screw is made accessible when the top is in place, and at the same time said top is held against rotation upon the plunger to maintain the alinement of 'the drivers with the passages 42. In Fig. 3 of the drawings, clearance-spaces will be seen between the edges of the plate 54 and the inner 'walls of the slots 52 and also about the sleeve `32 in the opening 575.Y In assembling the drivers 44 upon their plunger, with the top24 removed, the ends of the four front drivers are placed in the plateopenings 48 and the plate 54' slipped from the rear over the surface of the plate 46 until its edges enter the driver-slots 52. The clearancespaces in the slots 52 and the opening 55 yare suflicient to permit the rplate 54 to be thus moved until the rear driver may be inserted in its opening 48. Then, the plate 54 is shifted rearwardly into the slot in this rear driverand the openings in the two plates. and in the plunger are brought into registration. This allows the screw 58 to be inserted to secure these elements together. Thereupon, the top 24 may be placed upon the plunger, with the drivers in the passages 42 andthe rodhead 34 and the screw-head 59 in the respective passages 4I! and 60. f

A heel may be positioned on the heel-seat of a shoe carried by the top 24 for the operations upon it and the vnail-inserting pressure `resisted by tread and rear abutments. through the overhanging armV I2 is a screw V62 having fast upon its upper extremity a handwheel 64 and at its lower extremity a reduced portion 68 surrounded by a carrier-block 58. The carrier is held against displacement from the screw 82 by a retaining screw 10, the end of which enters a circumferential groove in the portionGG. To holdthe carrier` against rotation as Vthe screw 62 turns, a rod I2 rises from its rear and passes freely through an opening in the arm I2. VProjecting from the front of the carrier is a. lug 14, through which is threaded vertically a contactscrew 'I5 provided at its upper end with a fingerpiece 'I8 convenient for manipulation by the operator.r Pivoted at 88 upon the carrier is an abutment-plate 82, the outer portion of which is urged against the screw 16 by a torsion-springy 84 encircling the pivot-pin 88 Yand having its ends engaging, respectively, the carrier and plate. The Y spring holds the plate constantly against the screw, so it follows the latter, as it is adjusted toI give the proper angles to thev tread-surface of the plate for heels of different pitches.

Threaded vertically Between the ends of the frame-arm I2 is a forwardly and downwardly inclined passage 8E, in which is free to move longitudinally a screw 88. A tension-spring 90 joining the screw to the frame at the outer end of the passage holds against said frame a nut 92 upon the screw. A screw 94 threaded through the frame into a longitudinal slot 96 in thescrew 88 retains the latter screw against rotation while it is being adjusted by the nut 92. Attached to the forward extremity of the screw 88 by a bolt 98 is a transversely curved, padded rear abutment |00 against which a heel to be attached may rest. As the nut 92 is rotated,

the spring keeps it against the frame', and the abutmentr may be moved over the work-support to a greater or less distance to correctly position a heel upon the heel-seat of a supported shoe. n

There may be applied to the plunger I4 a shoesupporting top and a driver-assembly, furnishing the nailing design most suitable for the work to be performed. The' operator supplies a load of nails N to the passages 42, theirheads being supported upon the inclined ends 50 of thedrivers with the points resting against the inner sides of the passages. These points will-be initially a substantial distance below the upper surfacesof the top 24. With the'plunger I4 lowered, the plate 82 and abutment H10 are soV located vby the handwheel 64' and nut 9,2, respectively, that a shoe S may be ap-V plied to the support, and a heel H placed upon its heel-seat. The work may thus be introduced into the machine. The operator draws forward the lever 28, until the surfaces at the tread and rear of the heel, with which the abutments 82 and |08 contact, are close to these.` He may then release the lever, the work-support being retained in the position to which it is'moved by the friction device 2|. This leaves both hands of theoperator-free to position thejwork and adjust the. abutments by turning the screw I6 and the nut 92 until engagement is obtained which willhold the heel against slipping upon the heel-seat during the inserting operation. Thereupon, further forward movement4 of the lever first brings the work against the abutment, This causes the spring 28y to yield, and as the nailsV are being raised by the driversj through the spaces which exist between their points and the insole, the topk 24 is being forcedagainst said insole, this clamping the workby the force created by the compressed spring. When the nail-points reach the insole and are driven through it into the heel in an inwardly inclined direction, upon continued depression of the lever, the attachment of Ythe heel to the shoe is completed. Elevation ofthe lever lowers the support to release the work for its removal.
