20 Claims.

This invention relates to fluid-applying machines and is illustrated herein as embodied in a machine for applying cement to the edges of the upper portions of shoes.

In the manufacture of shoes, machines for applying marginal stripes of cement to one or both sides of work-pieces are commonly used. In applying cement to work-pieces an important problem to be dealt with is thevariation in the absorptive character of the Various shoe materials to be coated; the absorptive character or" some materials tending to take up the applied cement and to carry it away from their attaching surfaces, thus leaving such surfaces, if not enough cement is applied, insufficiently coated with cement, so that in subsequent assembling or folding operations there will be no firm adherence between the assembled or folded parts. Thus, it can be readily seen that work-pieces made up wholly or in part of a textile material such, for example, as the canvas upper parts of shoes of the tennis or sneaker type and the soft cloth lining parts of overshoes, because of their absorptive character require the application of a stripe of cement of greater thickness to their attaching surfaces than do those work-pieces made from a comparatively non-absorptive material such as leather. Accordingly, it is desirable, in machines or the type referred to, in order to obviate the necessity of passing the work through the machine several times, to make provision for insuring that there will be deposited by one application of cement a stripe of cement of sufficient thickness to cause the, edges of the coated work-pieces to adhere firmly to their associated parts when assembled therewith regardless of the absorptive character of the material coated. Furthermore, it is customary to provide shoe parts, such as those referred to above, with a stripe of cement of a width determined by the extent to which the marginal portion of the work-piece to which the cement is to be applied is to overlap the part to which it is to be cemented, since on some parts a wider overlapping marginal portion is require than on others.

' In view of the above, it is an object of the present invention to provide an improved fluidapplying machine by the use of which stripes of cement of ample thickness and of different widths may be applied to the marginal portions of workpieces, varying in absorptive character, by a single application. 7

One of the features of the invention resides in a novel recessed fluid carrying roll having deflecting means associated therewith whereby the fluid carried by the roll is deflected from the roll directly on to the work. In the illustrated embodi- I ment of the invention a rotatable cement-carrying roll is constructedand arranged to carry a large quantity of'cement in a recess by frictional drag. An inclined foot member is provided for engaging the cement carried by the roll and deflecting a sufilcient quantity of the cement from the recess in the roll to the work. Features of novelty are also to be recognized in the provision of applying members constructed and arranged for the carrying of a plurality of unusually thick ribbons of cement, together with the means for causing one, or more of these ribbons to be applied-to the work, thereby determining the width of a stripe of cement to be applied to the work. In the construction shown, foot members are provided having inclined ends which extend into the grooves of a cement-carrying roll between the roll and the work. The foot members are independently adjustable relatively to the roll so that one or more of the ribbons of cement may be deflected from the roll to the work. Also, as illustrated, thespaced ends of an adjustable regulating member extend into grooves formed in the cement-carrying roll to regulate the thicknesses of the ribbons of cement carried thereby. v

It is a further very desirable characteristic of the machine herein shown that the deflecting means may be adjusted relatively to thecement carrying roll so that all of the cement carried by the roll will be deflected from the roll to the work; thus the roll may be kept clean and cement prevented from accumulating upon thecementcarrying surfaces thereof.

Preferably, and as illustrated, the cement-applying machine has oppositely disposed cementapplying devices adapted to apply stripes of cement of the required widths and thicknesses to the opposite marginal portions of a work-piece with the cement-carrying portion of each groove or track and arranged to deflect as much of the stripe of cement as is wanted from the roll to the edge of the work.

The above and other features of the invention in a direction opposite to the inclined ends 46 of the upper deflectors 44. The lower edges 95 of the ends 94 are beveled to provide sharpened edge portions which, when moved into operative relation to the peripheries of the hub members '74, will engage the cement carried in the grooves 76 and cause the cement to be pushed out directly for the application to the lower surface of the work as the work is fed past the applying point. Adjustment of the deflectors 92 is effected by means of adjusting screws 98 threaded through the wall of the receptacle 64 and having their ends in engagement with downwardly projecting portions 100 of the deflectors 92. To enable the operator to clean the roll 54, the deflectors 92 may be adjusted to a position where their sharpened lower edges 95 contact with the smooth peripheral surfaces of the hub members '74, thereby deflecting all of the cement from the smooth peripheral surfaces of the hub members to the work. It will be seen from the foregoing that either the upper cement-applying device or the lower cement-ape plying device may be rendered ineffective to apply a stripe of cement to the edge of the work by adjustment of its deflector members out of contact with the cement-carrying portions of their respective grooves, or the width of a stripe of cement applied to either or both sides of a work-piece may be varied by rendering inactive one or more of the deflector members.

In order to assist the operator to feed the work to the applying rolls with the edge of the work in alinement with the inner edges of the rolls, a work gage 182 is provided having a tongue formed f in a downwardly projecting portion 110 and extending into a slot 104 in the lever 58. The gage 132 is held in adjusted position by means of a screw 106 extending through a slot 108 in the portion 110 and threaded into the lever 58. The work gage 102 is provided with a work-supporting table 112 having an upturned edge portion 11% which serves as a gage for the edge of the work. A holddown finger 116 overhangs the table 112 and acts to prevent the edge of'the work from curling as the work is advanced by rotation of the upper and lower rolls.

In the operation of the machine the fluid-carrying roll 54 is lowered from co-operation with the upper fluid-carrying roll 10, the work placed upon the lower roll 54 with its edge in contact with the upstanding edge portion 114 of the gage 102 and the carrier lever and lower roll 54 raised until the upper face of the work is forced against the upper roll 10. The work, gripped between the disks l6 and '72, is advanced by the rotation of the upper and lower rolls and cement applied to one or both sides of the work. When the entire edge of the work has passed beneath the rolls the roll 54 is lowered and the feed stopped in the manner as the rolls of the machine of Patent No. 1,330,360 referred to above.
