invention relates to machines for use in the manufacture of shoes; More part cu larly, it concerns such fastening-inserting apparatus as that employed for the attachment of heels by nailing;

1 So far asI am aware,ma chines used here tofore. for, securing heels to shoes have com,- prised distinct devices, as a jack and a heelclamp, for holding the shoe and heel for the attaching operation. IToieach "of these devices, the work-rportion's are separately applied, commonly in .areceiving position, from which they'aremoved into attaching rela- -tion,::or that in which the heel-seat of a shoe condition.

and correspondingend of .aflheel are alined, and thenbrought together, underv pressure,

for the driving of the attaching nails or' other fastenings. Insuch an apparatus, there is opportunity for wide variation in the positions which the shoe-portions mayassume, considered both 4 longitudinally and transversely of the shoe, and also angularlyabout the vertical axis ofthe heel, The-correctness of location of the portions is dependent upon the care ofthe heeling machine operator and his assistant and the manner in which, the apparatus is constructed and maintained in Even under favorable circumstances, there is opportunity for considerable departure-fromthe desiredrelation, and it is necessary to compensate for, such errors by bringing the heel to itsifinal form, as by trimming and breast'ing,after it'is in place upon the shoe. 1 This is opfii ito-objection, in thatthese operations addr'nateri'al'ly to the expense, since they require considerable skill,

and in performingthem i'the work maybe injured.

Accordingly, an object the present invention is to provide .afmachi'nfe "such as, in

1918, and in the continuingfapplication, Serial Number 47,6,659, filed June 11, 1921, patented Mar. 26 1,929, #1,706,504, and of which, as to common subject-matter, the present case is a continuation, by which machinecs'uch operations upon a shoe as those "mechanism is port. 7 i 1 above indicated maybe performed with accuracy and ease, and. which will permit the attachment of a heel in its final form, so that it requires thereafter neitherctrimming nor opening or jig-hole within saidheel. By so 'arranglng the projection that it will pass throughthe heel-seat of the shoe and enter the/heel, the relation between these ele- :ments 1S: fixed with precision, both longitudinally and transversely of the shoe, and there may be predetermination of therela- 'tion betweensuch shoe, its heel and the operating mechanism. iThis is without the5exerelse of special care and with minimum effort by the operator, and undisturbed by the 'manner 'in which the machine is assembled and adjusted-.- By having, a plurality of projections;or=positioning members to en "gage thefwork, the angular relation between theheel, heel-seat and operatingmechanisn'l -m'ay also be determined. Since I prefer to operateupon the'heelfrom within the shoe,

I may employ operating devices movable: in the Support, there being illustrated passages in said Support opening adjacent to the po si'tioni'ng means, inwhich passages act reciprocatory nail-drivers. more definitely locates the points of insertion This arrangement of the fastenings-than when the inserting independent of the worlcsup- In the accompanying drawing is shown one of the many embodiments which my invention may assume,

Pope, February 24', 1891. This includes a frame 10, in which side rods 12, 12 are mounted to reciprocate vertically under the influence of a cross-head 13 movable at the bottom of the frame by eccentric mechanism r 14- driven from a power-shaft 16. Miounted to slide vertically in the frame is a crosshead 18, movable by oscillatory cams 20 and 22 actuated by connections 24: to the side rods. Carried in vertical ways upon the cross-head is a slide 26, joined to saidcro'sshead 18 by 'avsc'rew 28. A rack and pinion 30, united at 32 to a treadle 534, permits the slide to be raised and lowered independently of the cross-head to apply preliminarypressure to the work. Movable in horizontal ways upon the top of the slide 26 is a works'upjtiort or jack 36, its travel manually in the ways allowing it to occupy 'either' a position drawn forward to facilitate the application of the work, or rearward beneath an abutment 37 for the attaching operation. The abutment extends horizontally across the top of the frame, in vertical alinement with the slide 26. The jack 36 has, rising from its upper portion, a post 38 terminat- Spaced from the plate is a die-block 1-2 carried upon the upper extremity of vertical rods 44 fixed to the plate and so spaced from each other as to give the die-block proper support. The periphery of the block 42 is of such si'zeand shape that the heel-portion of a shoe-upper may readily be placed over it, while its upper surface 4L6 generally conforms to the 'insole-surface'at the heel-seat. Formed verticall'y'through the die-block are nail-receiving passages 48, these being arranged in accordance with the particular nailing design which is to be employed for the attachment of the heels.

Guided to reciprocate axially in the post 38 is a stem 4-9. havingat its end, between the plate 40 and the block 42, a driver-plate 50, which is guided by the rods {l4 passing throughopenings in it. l\[ounted at their lower ends in the plate 50 are fastening-inserting devices, shown as in the form of drivers 52, these. having their upper extremities operating in the passages 48. Thebottom of the stem 49 lies in close proximity to'and is alined with a plunger Star-ranged for vertical movement in the slide. 26. This plunger is supported upon abell-cranlr-lever 56 fulcrumed upon the slide and joined by a link 58 to a bell-crank-lever 60, which may which. two are illustrated. These pins may be located at separated points along the longi- 1 tudinal axis of the die-block, and are sho vn as of suliicient height to pass through similarly spaced openings 8 in the heel-seat-portion of a supported shoe S and into registering jig-holes or openings h in a heel H which is to be attached. This heel may be in its final form, save for such superficial operations as burni'shing. The diameter of the openings and their location in the sh e and heel are such that when the work is assembled upon thejack in the manner just outlined and particularly illustrated in 3 of the drawing, the insertion of nails N, held in the passages 48 on the drivers 52, will attach the heel in the correct, predetermined location desired in the finished shoe and with the nails in a definite relation to the periphery of the heel. This result is attained because, having formed the surfaces within the openings 5 and 7t and located the corresponding guiding surfaces of the pins Stand lfhose of the dieblock-openings 48 in a predetermined relation, standard conditions will. have been established, which will govern every operation performed, without calling for the exercise of judgment or skill on the part of the op erator.

In heeling a shoe by my improved apparatus, the operator, with the jack 36 drawn out, loads the die-block-passages 48 with nails N, places the upper of a shoe Sabove the die block bringing the openings 8, which have been previously formed-in the heel-seat-portion of the 'insole, over the pins 64, and then applles a heel H with its openings it upon said pins. The shoe' p'ortions are now definitelyloca-ted with respect to each other and to the die-bloclr-openings, both longitudinal l y and transve'rsely;ofthe shoe and angular-1y, consldering afvertical axis through the heelseat. The-jack isthen thrust in-,.so that it is beneath the abutment 37, and its stem 39 l'alin 'ed, with the plungenfi. Preliminary pressure is thereuponput upon the work by screw2 8,"afctuated-by the treadle 34:, and the n'1a h 1ne started in operationjby raising a lever 66, cont1 olling the clutch mechanism, which-is not illustratedl Power is thus applied to operate the'cain 'mfechanjisinQO and 22, raising the jack under power to more firmly press the tread-surface of the heel against the abutment and upon the heel-seat of the shoe, and the drivers rise, forcing the nails N through the insole into the heel, thus completing the attachment. WV hen, at the end of the cycle, the jack is restored to its normal lowered position, it may be drawn out and the heeled shoe removed. The openings .9 in the insole may be concealed in any convenient manner. WVhile my invention has been described in connection With a heel-attaching machine, where it is of especial utility, it is to be understood that it may be. employed wherever it is desired to locate a heel upon a support for an operation upon it.
