This invention relates to work-positioning means and is illustrated as embodied in a fastening inserting machine particularly adapted for use inrepairing boot-s andshoes.

In repairing shoes, bothisoles and the top lifts of heels are oftensecured by wire staples inserted by the samemachine. To secure a neat appearance of the work and to be. properly effective, the fastenings which secure the sole of the shoe should be uniformly positioned at a suitable distance from the edge of the sole. Asthese. soles arepreviously preliminarily attachedto the shoes, for eX- ample by a few tacks, a gauge against which the edge of the sole bears is asatisfactory device. However, in securing top lif-ts,especially on wooden heels, it is customary to have the top heel and often rectangular or irregular pieces of stock are used for the purpose, these being trimmed to shape after they have been, attached. Such being the case, it is necessary for the gauge that is used for this work to bear against the heel below the" top lift and not against the top lift itself. Therefore, the gauge must be positioned in a lower plane, relatively to the nozzle or throat member of the machine, than the gauge that-is used in attaching soles. Furthermore, in some other kinds of work, for example when inserting fastenings across the butts of half soles, the gauges previously referredto are not helpful and would be in the Way.

It is, in view of the foregoing, an objectof the present invention to solve these diiiiculties by providing improved gauge mecha-' nism adapted to be used under the varying conditions met with inthe repairing of boots and shoes. v

Accordingly, a feature of the invention consists in a machine organization including a plurality ofgauge members each of which'is 7 suitable for a different class of work, and which is so arranged that any oneinaybe brought into operative position "and locked against the usual pressures which are met with in machines of this type. As illustrated,

needed or anothe one needs to be. substituted lift somewhat larger than the y for the. one in use. This shifting ofthe gauge 'cordingly, another feature of the invention consists in an arrangement of gauge members such that, when any one is 111 use, itsposition relative to the nozzle or throat member of the machine may be varied readily and the gauge held in adjusted position, also without the use of tools,- the use of which would necessarily slow down the operator. f

In the accompanyingdrawings, Fig. 1 is aside elevation'of a portion of. a stapling machine embodying the invention with a gauge for use when attaching toplifts to heels in operative position and with a gauge for use when attaching soles indicated in inoperative position; i 1g. 2 is a similar side elevation or a portion of the machine with e the position of the gauges interchanged, both gauges being shown in their entirety;

Fig. 3 is a front elevation of a portion of the machine, partly in section, with the top lift gauge in operative position andwiththe sole gauge in inoperative position;

of the machine; byset screws 36 which are tapped into each of the arms 38 of the member 32'. i The member 32 is provided with a T-slot the slide40, the member 32 is'provided with agib 42 held in position by set screws 44 and lock 'nuts 46. The slide 40'is provided on its upper surface with a toothed rack 48 by 'i vhich it may be moved forwardly and backwardly through the engagement therewith of'a'pini'on 50 mounted on a shaft 52. One

- end of this shaft is provided with an operating handle 54can'd the otherend with a,

friction washer 56', a friction spring 58"and "friction adjusting nut's'60l The slide 40 has a downwardlyiproj'ecting bracket 62 ('Fig. This bracket'62 is provided with a cross shaft 64 held in position by a set screw66-(Figs. 3

and On the shaft" 64 are pivotally mounted a forepart' gauge member'68 and a top lift gaugemember 7 0. Each ofthese gauge members is provided-'adjacent to' the shaft64 with a slightlytap'eredrib 7 2 an'dthe bracket62 is provided, also adjacent to the "shaft 64*, with a correspondingly slightly tapered groove 74' on each side thereof. Each ofth'e'gaug'e members is provided with a deuble counter bored hole 7 6co-axial with that through whichthe shaft 6'4passes. Lo-

cated in thecounter bored"hole of each gauge fi's' a compfress1onspr1ng'78 mounted on the sh'aft64'. Theouter end of 'this spring abuts on" a washer held on the outer threaded end ofthe shaft 64'by a nut 82. Theouter ends of the bosses containing the counterbores 76 areprovid'ed with handgrip knobs V order to bring either of the gauge 'members6'8, 7O intooperative position, thatigauge membe'r' is lifted up from its depending posi tion "until it" is"'substantially' horizontal.

lV-hen this-position isreached, its spring? 8 causes the gauge memberto be moved toward s the bracket'62, and the slightly tapered tongue 72 'enters'thecorrespondingly tapered groove'74,;the'spring movingthe gauge axi- I ally ofthe haa nui the tongue and groove 7 .are in complete engagement; The slight taper of-the tongue'and groove brings the gaugemember into proper vertical falinem'ent with the noz'zle26. The tongueandTgroove' furnish a rigid support for the auge against rotative downward or upward movement under pressure exerted by the shoe operated on, while the spring 78 is sufliciently strong to prevent any sidewise movement of the gauge. In order to bring either gauge into inoperative position, the reverse motions take place, to wit, the operator pulls on the knob 84 until the "tongue and" groove are disengaged and then swings the gauge downwardly out of the way so that the machine maybe used without any gauge'or the other gauge may be brought into operative position.

It will be noticed that the forepart gauge 68', as shown in Fig. 2, is positioned at a level such that the sole '86 being attached is positioned about midway of the height of the gauge surface; on the other hand, the top liftgauge 70, as shown'in operative position in Fig. 1, is oifset-sothat it is well below the; top lift 88. The top' lift is thus fastened at the desired fixed distance from the edge of the heel,'which maybe either wood or'lea'ther and, after being secured, it may be trimmed to fit the contour of the rest of the heel.

Attention is called to the fact that the gauge mechanism illustrated herein is of such a nature that'it can-be readily applied to outstanding machines without necessitating the use'of machine-shopfacilities. 7 E
