' This invention relates to gagesfor'cementing machines and is herein illustrated as embodied in a machine'for applying cement to the marginal portion of a shoe sole. r A

In the manufacture of shoes, the soles of which are attached by means of cement, it iscustomary to apply a marginal stripe of cement to the attaching surface ofsa sole. This marginalstripe extends from a point adjacent to the heel breast line around thetoe' end of the sole to a corresponding point upon the opposite side. Since the heel end of the sole is commonly secured by fastenings such as.nails,'it is not customary-to apply cement to this portion of the sole and,

' furthermore, the attaching of any portion of the heel seat of the sole by cement is a distincthindrance to the operation of heel seat fitting and requires the workman to tear the sole from the upper back to the heel breast line. This may readily damage the shoe.. Sinceit isnecessary for the operator of thecement-applyingmachine to position the sole in themaehine by eye, it is likely that the operator will either startthe stripe of cement forward of the heel breastline, thereby causing the :sole to be imperfectly attached, or

else, in an effort to avoidthisdifliculty, will apply cement to therear of the heel breast line where it is not wanted and where-it is wasted. Accordingly, an object ofthisinvention is to provide an improved sole-locating device or gage by means of which the starting position may be accurately determined and in accordance with the size of the sole.. In'the illustrated machine, and accordance with features of the invention; a stop gage movable into operative position to receive contact of an end of the work acts as an abutment to determine the starting position of the work, and operator-controlled means are provided for moving the gage from inoperative to; operative position.- When the feeding. movement of the Work is started, thegage is dropped to aninop- V erative position below the work. As illustrated also, the operating ,treadle of; a machine, having aipresseror feed roll mounted upon a movable bracket, is' interconnected with the movable support for the gage, the arrangement being such that the gage is moved to'inoperative position'as the feed roll is. moved to operative position to coact with the cement-applying roll which assists infeeding thework.

Indie-drawings,

Fig; 1' is a side elevation of a cementing ma chine embodying the inventiomand Fig. 2 is an angular view on an enlarged scale of the gage supportingand adjusting-' mecha'nism showing its relation to the work-engaging rolls of the cementing machine.

For the sake o'fillustration the machine is herein'shown as embodied in the sole cementing machine of Letters Patent of the United States No. 1,928,693, granted October 3, 1933,upon the application of AS. Johnson. The invention is not limited, however, to this particular cementapplying machine, for the gage may be applied to other machines which operate progressively upon the work. A piece ofwork such asa sole S is presented to the machine withv its edge against the driven edge'gage roll H! where it is grasped=between a presser roll [2 and a cement applying roll I4. J'Ihe rolls l2 and M are driven continuously during the use of the machine in opposite directions, thereby to cause the-sole to V be moved away from the operator, or to the left in Fig. 2. It is desired that the application of cement should commence approximatelyat the heel breast line l6 (Fig; 2)' and, to aid the operator in so positioning the work, there is provided a stop gage comprising an upright arm 3, and a flattened'gage portion 20. The gagev 20, normally positioned below the work,.may be raised to the position illustrated in Figs. 1 and.2 to receive contact of the heel end of the Work and act as a stop. against which the heel end of, the soleis positioned.

This stop age 20is adjustably mounted upon a lever 22 andis in advance of the feeding means. In operative or raised positionthe upper end of a the gage is at a level above the top of the presser roll 12; The lever 22 is'pivoted upon a stud 24 carriedby abracket 26 which is secured by a screw.28 to an enlargement upon the column 3ll which supports the machine. Inasmuch as the heel end of the sole willrvary in soles of different sizes, the stop gage 20 is adjustably connected to the lever 22. i To this end'thelower end of the arm I8 is bent at right angles and isrecessed at 32 .to give-iit an angular cross-section. The lever 22' has a projectingrtable portion 34 upon which this grooved end rests and the lever is provided with an overhanging lip.36; overlying the upright. portion of the'end of the arm.' Index marks 38onthe upper face of the end of the arm coact'with the forward edge of the lip ,portion 3B to indicate the position of the stop gage in accordance with the size of the sole, as designated: by numbers adjacent'to the index marks 38. To assist the. operator in moving the gage from one positionto another, there is provided I ahand lever 40 pivoted upon the, tableportion 551 surforrlca h j 3 y 34 and having a segmental toothed end 42 meshing with teeth 44 out upon the edge of the lower end of the gage arm. This lever is provided with a spring-pressed plunger 46 coacting with one of a series of dents 48 in the upper face of the table portion 34 so that the hand lever may be moved from one size position to another with a minimum of attention.

In this" particular cementing machine, the presser roll I2 is carried upon a shaft '50 journaled in a bracket 52 pivoted at 54 in the frame 56 of the machine. The cement-applying roll I4 is mounted upon a shaft 58 also journaled in the frame of the machine and the two shafts are interconnected by gears 60 which receivepower from a driving pulley 62 to drive the rolls in opposite directions. Cement is supplied from a receptacle 64 to the upper. face .of the cement-" applying roll which is surrounded by a casing 66 positioned ,along the shaft without interrupting the. driving, connection. The bracket 52 has a depending arm 14 to which there is pivotally secured a rod 16 passing. through a bushing 18 in the. frame and having thereon a collar 80. A spring 82 surrounding this rod between the bushing'andfthe arm 14 urges the presser roll l2 towardthe cement-applying roll l4; contact between. the two being prevented by a stop screw II. This screw 84 is adjusted when setting up the machine at the factory and determines the highest positionwhich the feed roll I! can assume. Another stop screw 86 coacts with the depending arm I4 of the bracket in order to allowthe operator to. adjust the spacing between thework-gripping rolls of the cementing machine in accordance with the thickness of the work. The machine is provided with a treadle 90 pivoted at the base of the column 30 and urged upwardly by a. tensionspring 92. In thetreadle 90 is shown in the depressed position which it assumes when an operator steps on it in order to present a piece of work to the Inachine. This treadle is connected by a treadle rod to a bell cranksli which is pivoted upon a bracket 98 .secured to the enlarged portion of the column 30-. A stop screw I00. carriedgon the treadle rod limits upward movement of the rod, under the impulse of the spring 92, when released bythe operator. The treadle rod has an extension I02 which is secured to the bent righthand end I04 (Fig. 2) of the stop-gage-supporting-lever 22. The upper arm of'thebell crank 9' is positioned to engage the collar 8| on the rod 16 connected to the pivoted bracket 14 which carries the presser roll l2, so that depression of the treadle is effective to lower the presser roll toan inoperative-position as shown in Fig. 1.

1. In. .the operation of the machine, .assuming that the stop gage 20 has been adjusted by means of the hand lever. 40 and that the edge gage i0 has been adjusted by the thumb screw I0, then the'sole S is positioned with its heel endin en gagement with the stop gage 20 and against the edgegage l0, and the treadle, which has been depressed. to the'position shown in Fig; 1 to permit insertion of a piece or work, is released therebyallowing the stop gage to drop and. the. sole to begripped between the coacting rolls l2 and I4.

Movements of the gage 20 and. the feed roll I2 are simultaneous and in opposite directions. Consequently, the stop gage 20 is removed from the path of feeding movement of the work before the rolls l2 and I4 grip the work to cause it to move forward. Cement will then be applied progressively around the margin of the sole and the sole removed when the stripe has reached a point on the other side opposite the starting point. This point can be readily determined by inspection and a stop gage is not needed for the purpose. The treadle is then again depressed to separate the coacting rolls and the sole removed and another one presented.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is: 1., In a cementing machine for operating progressively upon a piece of sheet material in a predetermined plane, feeding means, a gage movable from an inoperative into an operative position where it'will receive contact of an edge of the sheet material presented thereto and act as an abutment to determine thestarting position of the work, operator controlledmeans'for moving said gage from inoperative to operative position, and means for removing fsaid. gage from said position before the work isfed forward.
