MACHINE FOR OPERATING "UPON'SHOES.

v To alter/tom it mag concern:

Be it known that I, BENJAMIN F. MAYO, a citizen oi the United States, residing at Salem, in the county of Essex and State of lvlassac-husetts, have invented certain improvements in Machines for Operating upon Shoes, 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 machines for operating upon shoes, being here shownin connection with a heel-attaching machine.

Anobject of theinvention is to so organize a work-supporting member, as a j aclnpost, and a worlnpositioning member, as a bandclamp, that the work and positioning members may be brought readily into correct engagement'without danger of defacing the work by the relative movement between it and said positioning member. As heelattaching machines are commonly arranged, as the jack post carrying the shoe to which the heel is to be attached is swung in for the nailing operation, thewband-clamp, which has been raised. by its connection with the jack post to remove it from the path of the loader mechanism, descends so that the clamp and shoe converge to the operating position. When they thus meet through a simultaneous ,il'lOVOIl'lGIll), it may not be easy to properly introduce the rear portion of the shoe into theclamp, and the lowerwedge of the band may drag across and rub the upper. In accomplishing the previously-mentioned obj set, I provide for control of the movement of the worlcpositioning member independently of the work-supporting member. 'The positioning member, which as already indicated, may in a heel-attaching machine be the band-clamp, does not, as heretofore, move only under the influence of the worksupporting member or jack post, but may be rem iiorarily secured against movement for later release to move independently.

A turther object of the invention is to re duce the breakage of work gages and to render them readily reparable when broken. In heel-attaching machines, the breast gages, and particularly those which hold the top lifts, may be subjected to stresses which bend or break them. This may arise when the Specification of Letters Patent.

conditions, the gage may be pressed down-- -ward through the yield permitted at the clearance between the gage and swing plate and between the swing plate and nail block. There is also sometimes a depression formed in the swing plate extending beneath the gage, which is employed to produce a convex bottom to the heel. This throws a further strain upon the gage. I arrange the gage to receive such pressure with less liability to breakage by forming it in sections extending along the edge of the work, one of which sections is carried by andis yieldable upon the other. Preferably, the gage sections are connected by a spring, which is shown as located in recesses in the breast-engaging arm of the gage and is secured thereto by rivets.

An additional object of the invention is to provide for maintaining in correct relation a delivery mechanism and means for actuating an element thereof. In some shoe machinery. of which the herein illustrated heel-attaching machine furnishes an example,-a movable mechanism and a means for actuating it are situated upon parts of the machine which may not be in proper aline- .ment, so that the actuating movement is interfered with. Considering the specific instance oi'? the heel-attaching machine, a loader arm may be pivoted upon the frame of a machine, while the element which trips the nail gate oi the loader block is carried by the nail block cross-head. The release of the gate to deliver the nails to the nail block is effected by the contact oi. the gate with its trip when the cross-head is in its normal position, but an adjustment of the stroke of the crosshead, or even an incorrect initial relation of the parts, may cause the trip to lie outside the plane of movement of the gate, so that the tripping of the latter is not accomplished. In correcting such defects, I have so arranged the delivery or loader mechanism and the actuating or tripping means that their relative positions may be varied to correspond to the variation in the normal relation of the elements which support them. This adjustment, particularly in connection with loader mechanisms [for heel-attaching Eatented Dec. Ltd, 19211.

of the spindle 12 liecting lever 34. 'One arm machines, is preferably applied to the tripping means. The time of cooperation of the delivery mechanism and actuating means therefor may also be varied, I-having here shown the tripping member adjustable in angular position.

The accompanying drawings illustrate a form of my invention embodied in a heelattaching machine.

Figure 1 thereof is a side elevation of a portion of a heel-attaching machine, illustrating mere particularly the relation between the jack post and the band-clamp;

Fig. 2 is a top plan View of the heel and top lift holding mechanism and the loader mechanism, the jack post and band-clamp being removed;

Fig. 3 is a broken detail in rear elevation of the upper portion of the jack post;

Fig. 4 is a perspective view of the crosshead with the swing plate mounted thereon;

Fig. 5 shows in perspective a portion of the breast gage; and

Fig. 6 is a vertical sectional detail through the center of the swing post stud illustrating the manner of holding the nail gate trip thereon.

In the frame 10 are mounted for movement in the usual or any desired manner the oppositely arranged work-spindle 12 and cross-head 14. The cross-head carries the nail block 18, through openings in which act the drivers 20. At the lower extremity is mounted the jack slide or carrier 16, between lugs 22 depending from the under side of which is pivoted upon a pin 23 the jack post, including upper and lower sections 24 and 26, respectively. The section 26 is shown as mounted for move ment longitudinally of the section 24, the sectionsbeing locked in their normal position by a latch 30pivoted upon the section 26 and having its tripping portion extending downwardly along the section. At the bottom of the section 26 is the .usual pin 32 arranged to enter the opening of a last, as illustrated at L, this carrying the shoe S to which a heel is to be attached. The upper extremity of the post section 24 is divided, and between the separated portions, upon the pivot pin 23 as its fulcrum, is mounted a conof this lever is provided with a hook 36 connected, by a chain '38 passing over a sprocket 4O journaled upon the slide 16, to a vertically movableslide 42. This slide 42 is mounted in ways in a member 44 upon the frame and carries a band-clamp 46, the band 48 of which is arranged to receive the rear portion of the shoe upper, the lower edge of said band entering the rand crease, to hold it in position for the heel-attaching operation. The other arm of the lever 34 contacts with a screw 50 threaded through the front of the post section 24. As the jack post is swung outwardly upon its pivot this srrew forces down the hook 36 of the lever correspondingly, exerting tension upon the chain 38. Formed upon a segmental portion of the lever 34 is a series of ratchet teeth 52, with which coiiperates a latch device furnished by a detent 54 sliding in a sleeve or casing 56 threaded into one of the lugs 22. A spring 58 surrounding a spindle 60 of the detent between its body portion and a head of the casing 56 maintains the cooperation of the detent and ratchet teeth. T0 withdraw the detent from engagement with the teeth, hand lever 62 is pivoted to. the spindle 60 and fulcrumed upon an extension 64 from the lug below the sleeve 56.

. It extends downwardly along the jack section 24, where it m y be manipulated conveniently by the operator. There is also shown the usual detent 66 pivoted upon the section 24 of the jack post and arranged to engage a depression 68 in one of the lugs 22, thus serving to temporarily retain the jack post in its work-receiving position.

For the purpose of describing this feature of the invention, it will be assumed that the heel-attaching operation has just been completed, the jack post, lasted shoe and band-clamp being related as indicated in dotted lines in Fig. 1. At this time the chain 38 is slack. As the work spindle rises in the reversal of the measuring movement, the work and band-clamp remaining in the nailing position, the chain becomes taut. The operator then swings out the jack post to the position illustrated in full lines at the right of Fig. l, at the same time removing the heeled shoe. In this movement of the jack post the lever 34 acting through the chain raises the bandclamp a. distance equal to the measuring movement, the ratchet {teeth 52 slipping beneath the detent 54, and when the detent 66 engages its depression the band-clamp is locked by the engagement of the detent 54 and teeth. Conse uentlv when the 'ack post is returned to the operating position, the band-clamp will be held at such a height that the lower edge of the band will be at the level in whichthe rand crease will move when the jacked shoe is carried by the jack post into the operating position. When, therefore, the operator applies another lasted shoe to the pin 32 and forces down the jack post, the shoe enters the band with a substantially rectilinear move ment while said band is stationary, so that the engagement is perfect and there is no relative movement tending to scratch the work. The operator thereupon depresses the levers 62 and 30. This releases the connecting lever 34 and the jack post section 26 so that the band-clamp and work may be dropped together until the heel seat of the shoe rests upon the heel H carried by the swing plate. When the treadle isdepressed and the jack post eeseends in its measurdng movement, the j ack post sections are restored to their normal relation, latched together by the lever 80' ready for the application ofthe heel to the shoe.

Pivot'ed upon the cross-head 14 above the nail block 18 is a swing plate 70, this turning about a stud 72 projecting upwardly from the rear of the cross-head. Upon the swing plate are carried holders for heels and top lifts, these including forks 74 and 76, respectively, adjustablein guides 78, and breast gages 80 and 82, respectively. The

' heel gage may be constructed and arranged in the customarymanner, being drawn toward its fork 1n the gulde 78, as is also the top lift gage, by a spring 84:. The gage .82

has two arms, one of which, designated by i the numeral 86, is guided as is the heel gage,

while the contact arm of the gage is formed in two sections 88 and 90. The section .88 extends for a relatively short distance from the arm 86 and is shown as integral there with. It is continued by the alined section 90 to the end guide92. The section 90 is connected to the section 88 for relative movementtoward andfrom the nail block by a spring 9%, here shown as of leaf form and situatedin recesses 96 in the gage sections, the depth of these recesses being such that the top of the spring is flush with, or at least not higher than the top of the gage.

The spring may be secured to the sections by pairs of rivets 98, 98. The contact arm of the gage is shown as extending over a depression 100 in the swing plate, though this depression may or may not be used. VVhenpresent, it acts to form a convex surface upon the top lift as it is spanked on the heel.

If, as is sometimes the case,the top lift is thinner than the contact arm of the gage, the overhanging portion of the heel will bear upon it, and by moving it the amount of the clearance spaces between it and the swingplate or between the latter and the nail block or into the swing plate depression may tend to break or deform the contact arm. @n account, howewr, ot the independence of the sections, the outer one 90, upon which this pressure is brought, may yield sufficiently to usually prevent damage, or, if breakage occurs, it will be in the spring 94;. This part is inexpensive and may be readily renewedby cutting off the rivets, inserting a fresh spring and riveting it in place. j

. Nails are delivered to the nailblock by a loader mechanism, including an arm pivoted at 104 upon the frame 10 and carrying a perforatedblock 106, beneath which is pivoted the nail-supporting gate 108. A spring 110. exerts its tension to swing, the

nailgate frorndbeneath the block, thegate being retained in its nail-supporting positlon. by a latch pro ectlon 112. The gate is actuated to cause its release from the by adjustment of its actuating mechanism, T.

adjustably support thel projection on the stud to compensate for this. To this end, the stud 72 has its end projecting through the swing plate threaded at 116, this threaded portion being engaged by a nut 118 having an upward extension 120 externally threaded. Threaded upon the extension 120 is a sleeve 124 vertically adjustable by be ing turned upon the extension. lit is held in the position to which it is moved by a check nut 126 contacting with its upper extremity and also threaded upon the extension. At "its lower end is an annular flange 1255, upon which rests the hub 130 of the tripping projection 11a. The hub is free to turn about the sleeve, and near the upper end of the hub said sleeve is threaded externally at 132 to receive a nut 134:, which when turned down. against the hub fixes it as to its angular position.

if in the use of the machine it is found that the plane in which the nail gate moves when the loader block is swung over the nail block does not bring it into proper engagement with the trip 114i, the location of this tripping projection may be varied vertically by the organization just described. This is accomplished by releasing the nut 126 and turning the sleeve 124 up or down until the projection 11 i is found to be correctly engaged by the latch 112. The nut 13 1- being freed from its contact with the hub 130, the projection may be turned upon the flange 128 until the time at which the gate is tripped is such that the nails are properly delivered to the holes in the nail block.

The machine in its general operation may differ in no essential respect from the usual heel-attaching machines of this type and this will not particularly be described.
