Improvements in or relating to machines for assembling parts of boots or shoes.*

Claims.—(1.) A machine for assembling parts of boots and shoes, having, in combination, means for securing the upper to the inner sole; and mechanism for securing the upper to the rear end of the last adjacent to the cone thereof, said means and said mechanism being arranged for relative adjustment to accommodate lasts or shoes of different heights. (2.) A machine of the class described, having, in combination, a last-supporter, means for wiping an upper over an inner sole at the heel, means for securing the upper to the inner sole, and mechanism for securing the upper to the rear end of the last adjacent to the cone thereof, said mechanism being arranged for adjustment to accommodate lasts or shoes of different heights. (3.) A machine of the class described, having, in combination, means for securing an upper to an inner sole sustained upon a last, and fastening-inserting mechanism arranged to drive a fastening through the upper into the rear end of the last obliquely toward the sole of the last. (4.) A machine of the class described, having, in combination, a rest arranged for engagement with the rear end of a last, means for wiping an upper over an inner sole at the heel, means for securing the upper to the inner sole, and fastening-inserting mechanism arranged to drive a fastening obliquely toward the sole of the last into the rear end of the last. (5.) A machine for assembling parts of boots and shoes, having, in combination, means for supporting a last for longitudinal movement, means for pressing into

close relation to the rear end of the last an upper and counter sustained by the last, and means for yieldingly resisting longitudinal movement of the last. (6.) A machine of the character described, having, in combination, a stop arranged for engagement by the bottom of the last, a last-supporter arranged for movement toward the stop and arranged also for movement in the direction of the last, and means for yieldingly moving said last-supporter toward the stop constructed to resist movement of the last-supporter in the direction of the length of the last. (7.) A machine for assembling parts of boots and shoes, having, in combination, means for yieldingly supporting a last, a presser for engaging the rear end of the last adjacent to the sole, and a rigidly mounted wiper arranged for movement over the edge of the last, said presser and wiper being constructed for simultaneous movement longitudinally of the last.

No. 22156.—5th December, 1906.—UNITED SHOE MACHINERY COMPANY, of Paterson, State of New Jersey, United States of America, a corporation duly organized under the laws of said State of New Jersey, and having a place of business at 205 Lincoln Street, Boston, Massachusetts, United States of America (assignees of Joseph Gouldbourn, of Leicester, England, Engineer). Improvements in or relating to machines for loading heels or for attaching them to boots and shoes.*

Claims.—(1.) A machine for inserting nails in heels, having, in combination, a nail-driving mechanism, a plurality of heel-holders arranged for movement into and out of operative relation to said mechanism, a nail-transferrer for supplying nails to said mechanism arranged for a reciprocatory movement between a nail-receiving position and a nail-delivering position, and means for moving said holders successively into operative position arranged to be brought into operation by successive reciprocations of said nail-transferrer. (2.) A machine for inserting nails, having, in combination, a die-block provided with nail passages and a nail-transferrer for supplying nails to said die-block, arranged for movement laterally of the die-block from a nail-receiving position into a nail-delivering position above the die-block, and means for yieldingly depressing said transferrer in its movement between said positions whereby it is brought into close relation to the upper face of the die-block. (3.) A machine for inserting nails in heels, having, in combination, a die-block arranged for movement into and out of operative position and provided with nail-receiving passages, a nail-transferrer for supplying nails to the die-block arranged for movement from a nail-receiving position at one side of the die-block into a nail-delivering position above the die-block, and means arranged to be brought into operation in the movement of the nail-transferrer into delivering position for adjusting the die-block into a predetermined position. (4.) A machine for inserting nails in heels, having, in combination, a plurality of heel-holders arranged to be brought successively into operative relation to said mechanism, gauges carried by the holders for retaining heels in position upon the holders, and means for adjusting simultaneously the gauges upon the several holders.
