Gill, Melrose, Mass., assígnor to United Shoe Machinery Corporation, Fleming ton, N. J., a corporation of New Jersey Original application December 12, 1942, Serial No. 468,774. Divided and thisfapplication July 12, 1944, Serial No. 544,495 ' - 6 Claims. l This invention relates to machines by which fastenings are driven to effect the connection of work-pieces. Machines of this character may be employed for the attachment to shoes of heel parts,v as bases and lifts of rubber or the like. The present case is a division of an application filed in my name in the United States Patent Oflice Aon December l2, 1942, and bearing the Se rial No.>468,774. A second divisional application directed to the means which insures the matching and registra tion of the elements of the fastening-inserting mechanism was ñled in my name on July 12, 1944, with the Serial No. 544,494, it'having matured on May 29, 1945, into Patent No. 2,376,910. An object -of the invention, and in connection 2 I0 a die-block l2, in which are vertical passages I4 to receive the fastenings to be inserted. These passages may include a multiple of all the de signs which are to be employed. The die-block is shown as separately mounted in place by screws i6 threaded vertically into the frame. The por tion of the die-block with which the work con tacts is provided by a plate i8, of which depend-> ing quills 24 are a part. These quills may be formed integrally With the plate or made sepa rately and ñxedly attached thereto. The plate with its projections is carried in ways 20 at the underside of the die and latched in place by a spring-plunger 22, movable through said die and entering an opening at the front of the plate. , The passages through the plate, corresponding to with a fastening-inserting die or other work those of a particular nailing design in the die, abutment in a heel-attaching machine, such terminate in the quills 24. 'I'he quills enter the abutment being provided with a projection or surface of a rubber or other elastic lift T to be projections against which the work is pressed, is 20 attached, and compress the material over the area to avoid interference by engagement with the therein through which the attaching fastenings projections upon the introduction of the heel are to be driven. 'I‘hese fastenings pass through parts into attaching position. This result is this lift and a heel-base, carried at the underside gained by combining with the abutment a yield able guard having one or more openings within of the die-quill-plate by holding mechanism M, and into the heel-seat of a shoe which is pressed which the projection or projections normally lie, against the base by a vertically reciprocable jack said guard presenting a plane surface to the heel (not illustrated) upon which it is supported. The parts. This guard may be furnished by a plate fastenings are preferably cut from strings of liber guided for movement upon the die and forced by and delivered by a loader-block 30 to the die springs into its normal position, in which the pro 30 block-passages I4. The insertion of the fasten jections or quills are shrouded. The plate yields ings in the Work is effected by a gang of recip when :clamping pressure is applied, so the quill rocatory drivers 34, which may ñrst act as awls, ends will project outside the plate-openings for as in the previously mentioned La Chapelle pat engagement with the heel-part, to enter, for ex ent. The driver-assembly operates in the corre ample, the material surrounding the nail-pas 35 sponding group of multiple die-passages I4, it sages in a rubber or other compressible lift. being changed, together with the quill-plate I8, In the accompanying drawing: as the inserting design varies. Fig. 1 shows, in front elevation with elements in Were it necessary to insert the lifts into the section, portions of a heel-attaching machine holder M in contact with the ends of the spaced with which the present invention is more directly 40 quills 24, there would tend to be interference with concerned; the movement. To prevent this, the lower por Fig. 2 is an enlarged transverse sectional de tail through the lift-engaging elements, taken prior to the clamping of the work; and tions of the quills are shrouded by a guard-plate |08. This plate is movable in a recess at the. underside of the quill-plate I8, it being held Fig. 3 is a View similar to Fig. 2, but with the 45 against downward displacement by the heads of screws 102, which extend through openings in The general organization of a heel-attaching the quill-plate and are threaded vertically into machine to which the present invention is ap the guard-plate. In the guard-plate is a con plicable may be that disclosed in Letters Patent tracted opening 1M for the reception of each of the United States No. 2,293,624, Parkhurst, 50 quill with relatively small clearance, the lower August 18, 1942*, and in certain respects in No. end of each quill lying normally above the lower 2,207,742, La Chapelle, July 16, 1940, these ma surface of the plate (Fig. 2). In its lowered Work under pressure. chines being designed for the attachment of heel bases and top-lifts to shoes. In apparatus of this character, there is mounted upon a frame position, the guard-plate is yieldably maintained by expansion-springs |66 having their opposite extremities seated in recesses in the quill-plate 2,408,845 3 and guard-plate. The underface of the guard plate presents an extended surface free from interfering projections when the toplifts are slid into place in the holder M. Yet, when clamping pressure goes upon the work (Fig. 3), as a result of the elevation of the shoe-supporting jack in preparation for the insertion of the fastenings by the drivers 34, the guard-plate yields freely, so the quills lie outside the plate-openings and enter the substance of a rubber lift. Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is: l. In a heel-attaching machine, a heel-abut ment provided with a projection againstv which the work is pressed, and a yieldable guard hav ing a, contracted opening Within which the pro jection normally lies, said guard presenting to heel-ports about the opening an extended plane surface-for engagement with the tread-surfaces of said heel-parts during their introduction into the machine. 2. The combination with a- fastening-inserting die provided with projections against which the work is pressed, of a guard-plate yieldable upon the die by contact with the work and having openings within which the projections normally lie. 3. The combination with a fastening-insert ing die including a quill-plate provided with a ~" recess, of a guard-plate guided for movement; in the recess and having openings in which the quills lie with their ends normally Within the openings, and springs interposed between the quill-plate and the guard-plate and permitting 4 yield of said guard-plate so the quill-ends may project outside the openings. ' 4. In a heel-attaching machine provided with reciprocatory drivers, the combination with a fas tening-inserting die provided with openings and projections from its lower face through which the openings are continued and through which the drivers reciprocate, of a guard-plate yield able upon the die under the iníluence of a heel to be attached and having an opening individual to each projection and in which said projection normally lies shrouded by the plate. 5. In a heel-attaching machine provided with reciprocatory drivers, the combination with a fas tening-inserting die provided with openings and projections from its lower face through which the openings are continued and through which the drivers reciprocate, of a holder for a heel to be attached associated with the die, and a guard plate yieldable upon the die under the influence of. a heel to be attached and having openings into which the projections extend, said guard-plate presenting a surface along which a heel may be slid into the holder without interference by the projections. 6. In a heel-attaching machine, the combina tion of a heel-abutment provided with a projec tion against which the work is pressed, of a yield able guard having an opening Within which the projection normally lies, said guard presenting a plane surface for engagement with heel-parts, and a holder situated below the abutment and into which the heel-part may be slid guided by the plane surface of the guard.
