UNITED STATES PATENT: oFFicE.

WILFRID THOMAS MIN'ETT, OF. LEICESTER,-ENGLAND, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PA'IERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed July 2,

This invention relates to the attachment of the heels of shoes, and is particularly concerned with the attaching, from the inside of shoes,-o-f such relatively high and heavily curved heels as those of the Louis type. a

'In attaching heels of this character, it'

has been usual, in applying pressure to retain them upon the heel-seats of the shoes for nailing, to employ an abutment for the tread-surface and an abutment for the rear of the heel, as shown, for example, in United States Patent No. 1,269,654, Standish, J une.

great resistance to displacement of the heels,

other types of heels call for the use of longer attaching nails and heavier pressure to be exerted upon the tread-face, and the customary devices may not hold such heels securely. Accordingly, an object of the preent invention is to provide a heel-ho-ldmg device, which, while giving ample clearance for the positioning and removal of the work, is adapted to retain a heel, and especially the rear portion of a heel having a considerable slope, rigidly against such forces as may be exerted in driving a number of comparatively long nails. This ob ect I at tain by the provision, in apparatus for attaching heels, of means for applying pressureto different portions of such heels, as to the tread-surface and to the rear surface, their being a member connecting one of said pressure-applying means to the other, to

cause its movement, and a member connect-g ing the pressure-applying means thus moved to a relatively fixed point, to modify its movement. The pressureapplying meansthe movement of which is thus modified may be a rear abutment movable through a link by the tread-abutment,"and" the movementmodifying member, which may be a link connected to the. rear abutment and to the machine frame, may act as a brace against the pressure of the tread-abutment, and may also cause the rear abutment to be so posinnnn-Ar'raonrne MACHINE-L 1924.

tioned as to give the desired clearance for the handl ng of the work.

The above and other objects of the invention Wlll become apparent from a consider ation of the following description, given by to which the vertical abutment-link is piv-' oted. 7 At lO -appears a portion of the column or frame of such a heel-attaching machine as that disclosed in United States Patent No. 1,195,13 Gouldbourn, August 15, 1916, this frame supporting a jack 12, through which the attaching nails are driven, and also having mounted to reciprocate upon it a pressure-head 14 The head carries a pressure member or abutment 16, having its lower face formedand arranged to contact with the tread-surface of a heel H app-lied to the heel-seat of a jacked shoe S. The abutment 16 may be adjusted from front to rear of the machine upon the head by a screw 18, and may also be moved angularly in the same general direction by a screw 20. These adjustments permit the abutment 16 to be positioned for, proper contact with heels of different form. I

On account of the angle at which the. tread-surfaces of Louis and like heels lie with relation to the heel-seats, as is well illustrated in Fig. 1 of the drawing, pressure applied by the abutment 16 results in a substantially horizontal component toward the rear of the machine, this tending to displacethe heel from the shoe. This must be resisted in clamping such heels for nailing. It is also desirable to hold the extreme rear portion of the heel firmly in contact with the heel seat, to insure a tight crease when the attaching nails are driven.

F or these purposes, there is arranged for engagem'ent with what is normally the upper and rear curved portion of the heel H an abutment 22, pivoted upon a' carrier 24, this pivotal mounting allowing the abutment to adjust itself. to different inclinations of this heel-surface. Toactuate the rear abutlit) ment, so it may exert its pressure simultaneously with'that of the tread-abutment, it is movable under the control of the latter 7 by a connection, preferably consisting of alink 26 pivoted both to the carrier 24 and to a divided bracket 28 pro ecting rearwardly from the pressure-head. This movement of the rear abutment is modified to change its direction of travel under the influence of the tread pressure'member, and it is braced during the final application of pressure and the nailing operation by a second connection, independent of that to the treadabutment. This is "shown as consisting of a link 30 joi'nedto the carrier and pivoted to some such relatively fixed point as a bracket 32 mounted upon the column 10 at the rear of the jack.

The shoe El having been placed upon the jack and theheel H applied to the heel-seat, the head 14 descends Vertically in the operation "of the machine, carrying the abutment 16 in a straight path, to bring its end face into clamping engagement with the tread-surface of the heel. Priorto start ing the machine in operation and during the application of the work to the jack, the rear abutment has been held elevated by the link 26, it occupying "the position illustrated'in dotted lines in Fig. l or" the drawing. This is well to the rear under the influence of the link 80 which. as the head rises, drawsthe carrier away from the jack. The resulting position of the rear abutment so removes it from the aok that interleren'ce in the application'o'l' the shoe and heel is avoided. During the downward movement of the tread abu'tment, the link 26 lowers the abutment 22, while the link 30, turning upon the fa e, carries said abutinent forward trans sely of the path'oi the tread abu'tment into engagement with the rear of the heel. Vt hen this pressureapplyingmovement is completed, the link 30 occupies a substantially--horizontal -position, so that the horizontal component oi? theapplied force'previouslyreferred to is V 7 through theopenmgs. 58. Thus freed. from directly resistedby this connection to the "frame, with "practically no stress tending to disengage the 5 abutment from the work. The nails having been driven through the heel-seat of the shoe into the heel, the head t rises, and as the tread-abutment is elevated thereby, the rear abutment is also lifted from theheel and carried back clear of the jack, ready for the removal of the work and the application'oi' thesuoceeding shoe and heel.

To adapt the member 22 for effective cooperation with heels of different forms or dimensions, means are provided for varying both the point to which it moves downwardly'and also the eitent of-its'travel toward the jaclr. For tliis' purpOseQthe link26 is swiveled ate to the carrier 24, and is inember'22may be raised or lowered.

A pivotpin a l, which turns in thebracl zet 32 upon the frame, has

a. threaded opening, which the sleeve ongages. Rotating the sleeve will draw the abutment member in or out, thus adjusting the pressure-applying position of the out horizontally. To more precisely no the angle at which the link 30 lies whenresisting'the nailipressure, so that its bracing action may be most e'liiective, the bracket is 'fOlllfietl upon a slide movable vertically upon the column and clamped by a screwed For some classes of work, it may be desired not to employ the rear abutment. To permit it to easily be put out of action, the pivotal connection to the bracket 28 is'made readily detachable. For this purpose, the pins l0 are surrounded by flanged sleeves 50, the outerdiameter or which is such that thev litalined perforations 52, 52in the Ehe sleeves are held in engagement with the bracket-perforations, when employed, by enter annular grooves 56, 56 in the pins. Through the -front wall or" the bracket, from the perforations 5:2, 52, are contracted openings 58,
