HEEL-ATTAOHING MACHINE.

This invention relates to the attachment of theheels of shoes, and is particularly concerned with the attaching, from the 1nside of shoes, of such relatively high and heavily curved heels as those of the Louis ln 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, June 18, 1918. Here, the rear abutment is mounted upon the same head that carries the tread-abutment, this arrangement giving the necessary clearance for easy positioning of the shoe and heel and subsequent removal of the heeled shoe. WVhile such a construction is satisfactorily employed when attaching heels by short nails, which do not require heavy drlving pressure, nor, consequently, :gr-eat resistance to displacement of the heels, other types of heels require longer attaching nails and heavier pressure to be exerted upon the treadface,'and the customary devices may not hold such heels securely. Accordingly, an object of the present invention is to provide a heel-holding device, which, while giving ample clearance for the positionlng and removal of the work, is adapted toretain 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 object I attain by the provision, in apparatus for attaching heels, of means for applying pressure to diflerent portions of such heels, as to the tread-surface and to the rear surface, the latter means being retained against rearward movement, or braced independently of its support to resist the applied pressure. The pressure means preferably consist of abutments for the tread and rearportions of the heel, which move in the operation of the machine toward and from the heel in dit ferent directions, the rear abutment being movable transversely of the path of the tread-abutment. This latter movement gives the desired clearance for handling the work.

The above and other objects. of the in. vention will become apparent from a con sideration of the following description,

' machine, is shown in side elevation.

At 10 appears a part of the column'or frame ofsuch a heel-attaching machine as is disclosed in United States Patent No. 1,- 285,785, Negns & Charles, Nov. 26, 1918,

this frame supporting a. jack 12, through which the attaching nails are driven and also having mounted upon it a pressurehead 14. A pressure member or abutment 16 is carried by the head, its lower face being formed and arranged to contact with the tread-surface of a heel H applied to the heel-seat of a jacked shoe S. The head maybe arranged, as in the patent just cited, to be reciprocated from front to rear of the machine as well as moved vertically, the first mentioned movement being to free the jack for the application and removal of the work, while the vertical movement places pressure upon the work, to hold the heel in position during the nailing operation.

On account of the angle at which the treadsurfaces of Louis and like heels lie with relation to the heel-seats, as is well'illustrated in the drawing, pressure applied by the abutment 16 results in a substantially horizontal component toward the rear of the machine, this tending to displace the 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 atight crease when attaching nails are driven. For these purposes, there is pivoted at a point 17 upon the frame fixed against movementin the operation of the machine an arm 18 having, eX tending longitudinally, a socket'to receive the shank 20 of a rear pressure-applying member or abutment 22. This abutment is so curved as to approximately conform to what is normally the rear upper portion of a heel of the'Louis-type. The shank 20 of the abutment 22 may be adjustably clamped in place in its socket by a screw 24, which connects opposite divided portions of the wall at the under side of the socket. By this means, the member 22 may be fixed in position, to bcstco-operate with heels of different contours. A. spring 26,connecting the arm 18 and the frame or other relatively fixed point, furnishes a support for the abutment member 22, holding it normally raised in such position that it will be above and to the rear of the jack as the arm is turned about the pivot 17. This permits the application of work to the jack and its removal from said jack without interference. To move the abutment 22 into pressure-applying engagement with the rear of the heel, there is carried upon an inward extension of the abutment 16 a depending contact member 28, the extended lower surface of which is arranged to engage an upward projection from the member 22. This projection is preferably in the form of .a screw 30 threaded into a boss in the abutment and held in the position to which it may be adjusted by a nut 32. 1 I

The shoe S having been placed upon the jack and the heel H applied to the heel-seat, the machine is started in operation, and the head 14 descends. In this movement, the contact-portion 28 first strikes the screw 80, swinging the rear abutment 22 downwardly and outwardly about its pivot 17 against the tension of the spring 26 until, when full pressure has been applied by the abutment 16 to the tread-surface of the heel, the abutment 22'is in firm engagement with the rear surface, holding it closely to the heel-seat. At this time, the arm 18 is substantially horizontal, furnishing a most effective brace resisting the heel-displacing component of the pressure upon the tread. It will be seen that while the application of pressure by the rear abutment is more directly influenced by the tread-abutment, a modifying action is exercised by the connection of the arm 18 to the frame. This 7 alters the movement of the rear abutment,

causing it to travel in a path transverse to that of the tread-abutment. The proper relation between the pressure supplied by the two abutments is insured. by adjustment of the screw 30, this adapting the machine to operate to the best advantage upon the particular form of heel to be attached. With this adjustment is combined that of the stem 20 within the arm 18 to vary the effective length of the latter, so that the desired results maybe attained for heels of all curvatures and pitches. The heel having been thus clamped in place, the drivers rise in the jack to force the attaching nails through the heel-seat into the heel for its attachment. Then the head 14 is elevated, permitting the rear abutment to be lifted by its spring and swung rearwardly out of the way of the work. Since, in the form of heel-attaching machine of the patent previously referred to, the pressure-head 14 has, after the attaching operation, a rearward, as well as upward movement, there is shown between the pressure-surface of the abutment 16 and the projection 28, a recess 8 into which the screw may pass as the abutment member 22 is elevated. I
