HOLDER FOR HEELS OR TOP-LIFTS.

Application filed February 3, 1908.

To all whom it may concern Be it known that I, FREDERICK W. GLEA- son, a citizen of the United States, residing at Lestershire, in the county of Broome and State of New York, have invented certain Improvements in Holders for Heels or Top- Lifts, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to holders for heels or top lifts and more particularly to holders for use in heel attaching machines.

In the use of heel attaching machines now employed in the manufacture of boots and shoes it is commonly found desirable in changing from one size of heel to another to maintain the rearmost point of the new heel in substantially the same position during the attaching operation as that occupied by the corresponding point of the previous heel. This is occasioned by the fact that in attaching heels of different sizes the rearmost nail in each heel is generally driven from the same driver passage in the nail block. Also in heel attaching machines adapted to spank a top lift upon a previously attached heel it is commonly desirable in changing from one size to another that the top lifts of different sizes be supported with their rearmost points in the same predetermined position in order that each top lift may be suitably presented to its heel.

I-Ieretofore in heel attaching machines the heel holders and top lift holders have been so constructed and arranged that in changing the size of heels it has been necessary to manually adjust the holders in order to su port the rearmost point of the new heel or top lift in the same position as that in which the corresponding point of the previous heel or top lift has been located.

An object of the present invention is to provide a holder for heels or top lifts by which the necessity of these adjustments may be obviated.

An important object of the invention is to provide an improved holder for heels or top lifts constructed to sustain blanks of different sizes with their rearmost points in the same position longitudinally of the holder, and to center the blanks laterally of the holder. The preferred construction herein shown and described comprises a gage con- Specification of Letters Patent.

Serial No. 414,079.

structed to limit rearward movement of a blank in the holder and formed to limit this movement to the same predetermined point regardless of the size of the blank and means for pressing a blank into engagement with said gage. To limit said rearward movement of the blank upon the holder the rear gage is provided with a stop surface or abutment against which the blank is pressed and which is so formed as to cause the rear ends of blanks of different sizes to be retained in the same position longitudinally of the holder. A breast gage is provided to press the blank against the rear gage arranged for movement longitudinally of the holder and held yieldingly toward the rear gage. To the end that the rear ends of the blanks may be centered laterally, the rear gage is further provided with a pair of spring-pressed members arranged to engage the edges of a blank upon opposite sides and to yield equally in opposite directions as the blank is moved rearwardly toward the abutment which limits its movement. The breast gage is preferably formed to engage the breast edge of the blank at two laterally spaced points in order that it may exert a rotary positioning action upon the blank in the event that the longitudinal axis of the blank is out of parallelism with that of the holder.

Other features of the invention, the ad-v vantages of which will be apparent to one skilled in the art, will be hereinafter described and defined in the claims.

In the drawings which illustrate one embodiment of the invention, Figure 1 is a view in perspective of a portion of a well known form of heel attaching machine equipped with holders embodying the in vention; Fig. 2 is a plan view of the holders shown in Fig. 1; Fig. 3 is an enlarged fragmentary plan view illustrating the relative positions of the rear gage and the nail block hereinafter referred to; and Fig. 4 is a perspective view illustrating the construction of the rear gage.

Referring to the drawings, the reference numeral 2 indicates a heel holder and 4: a top lift holder carried by a plate 6 mounted for swinging movement in a horizontal plane over the nail block 8. It will be understood that in the operation of the ma chine to which the present invention is shown applied the plate 6, after a heel has with a lateral been attached to a shoe by nails driven from the nail passages of the nail block, is moved to bring the top lift holder into the position previously occupied by the heel holder. Secured to the upper face of the plate 6 are guideway plates 14 and 15 which cooperate with said plate to form guideways for the reception of the shanks of the gages hereinafter described. As will appear from the drawings the construction of the gages is the same for the two holders. Each holder comprises a rear gage 10 and a breast gage 12, the shanks 18 and 16 of which are received in the guideways above referred to. The shank of each rear gage is provided extension 17 upon which is formeda stop surface or abutment 20 with which the rear end of a lift has engagement. As will appear from Fig. 3 the surface 20 is of slightly curved contour in plan. Said surface is preferably so formed that it will locate the inner ends of lifts of different sizes in substantially the same position longitudinally of the holder. This result may be secured for example by giving said surface 20 a radius of curvature greater than that of the lift of least convexity which is to be retained upon the holder. It will be understood, however, that if this surface is shaped in other ways to locate the rear ends of different sized lifts in substantially the same position. longitudinally of the holder it will be suiiicient to secure the object of the present invention.

Pivotally secured upon the under side of the lateral extension 17 are two arms 22 pivoted at 24. The arms 22 are provided with inter-meshing gears 26 and, as will'appear from Fig. 3, are arranged in a symmetrical relatlon to the surface 20 above re ferred to. The forward end of the arms 22' are held yieldingly together by a spring 28. The approaching movement of the arms 22 is limited by a pin 30 mounted upon one of the arms and working in a slot in the lateralextension 17. Outward movement of the arms 22 is limited by a shoulder 32 ar ranged to have contact with the extension 17. In the holder shown on the drawings each rear gage is provided with means for adjusting it longitudinally of the holder comprising a thumb screw 38 threaded in a projection 36 upon the shank of the gage and rotatably supported in a bridge 40 at the rear of the plate 6. I

Each breast gage 12 in the holder shown comprises a straight bar formed as a lateral extension of the shank 16. The breast gage is pressed yieldingly toward the rear gage by a spring 42 which should be of sufficient strength to move a heel or top lift rearwardly into engagement with the surface 20 against the resistance of the spring-actuated arms 22. In the construction shown, the tension of the spring 42 may be varied by changing the location of the rear end of the spring in the series of holes H1 in the plate 6.

In the use of a holder such as is illustrated on the drawings, it will be understood that the rear gage 10 is given a suitable position to insure that the rear end of a heel or top lift will lie in proper relation to the rearmost nail passage of the nail block. When a rear gage has thus been properly adjusted no further adjustment will ordinarily be re quired in attaching heels and top lifts of difi'erentsizes. Variation in length of a blank is accommodated by the yielding breast gage and as will be apparent from the drawings variation in width or curvature of the rear end of a blank is taken care of by the rear gage above described. In inserting a blank in a holder the breast gage is retracted and the blank placed between the breast gage and the rear gage in approximately the correct position. It will be seen that when the breast gage is released it will press the blank rearwardly into engagement with the abutment 20 upon the rear gage. As the blank is moved rearwardly it separates the arms 22 which have engagement with the edges of the blanks upon opposite sides and yield equally and thus center the rear end of the blank laterally. Should a blank be initially placed with its longitudinal axis slightly out of parallelism with that of the holder it will be understood that the breast gage 12 will straighten the lift, partially rotating it into a proper position.

The holder shown on the drawings is not only adapted to accommodate blanks of different sizes without readjustment of the rear gages, but is also advantageous in that it retains a blank securely in position. It will be observed that in the use of the holder shown the blank is not only gripped longitudinally between the abutment 20 and the yielding breast gage, but is also engaged yieldingly at the sides by the spring-pressed arms 22. Liability of a top lift, for example, being dislodged from the holder as the plate 6 is swung automatically into top lift attaching position is thus effectually prevented.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A blank holder for a heeling machine, comprising a rear page including a normally stationary but adjustable member having a stop surface concaved upon a larger radius than the curved end of a blank, and a pair of blank centering arms pivotally mounted on and adjustable with said member and extending obliquely forwardly on either side of the center of the stop surface, together with a breast gage mounted for bodily movement toward and from the rear ga 2. In a holder for heels or top lifts, the

combination with a rear gage formed to locate the rear ends of blanks of difierent sizes in substantially the same position longitudinally of the holder and constructed and arranged for adjustment to permit variation of the position of the rear end of a blank, of relatively movable members for engaging the rear end of the blank to center it laterally of the holder, the said members being mounted upon the rear gage and adjustable with it, and means for positioning the blank angularly and pressing it into engagement with said rear gage.

3. A holder for heels or top lifts having, in combination, a rear gage adjustable forwardly and rearwardly and provided with a curved heel engaging face of such curvature that it can only engage at one point any heel or top lift to be handled, a spring actuated breast engaging means movable toward and from said rear gage, and laterally acting centering means arranged to engage a heel or lift between its rear end and its breast end.

4. A holder for top lifts, having in combinatioil, a rear gage having a work engaging face curved to engage a lift at a single point only on its curved end, a breast gage for holding a blank in engagement with said rear gage and a plurality of springpressed members arranged to grip the blank upon opposite sides while so held and center the rear end of the blank laterally in its holder.

5. A holder for heels or top lifts, having in combination, an adjustable rear gage, a plurality of relatively movable members v shaped to engage the rear portion of a blank and arranged to center it in the holder, said members being adjustable simultaneously with the rear gage, and a breast gage for holding the blank in engagement with said rear gage.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
