15 Claims.

This invention relates to the application of cement to shoe parts and is herein illustrated as embodied in a machine for coating the peripheral portion of an unattached moccasin toe piece.

In the mocassin type of shoe it is desirable to have a well dened ridge running around the toe and in practice this is accomplished by beveling the upper and the toe piece, turning the beveled portion of the toe piece outwardly to form a ange, and joining the beveled edges face to face by a heavy line of stitching. Since the beveled edges of the upper and toe piece are rather abrupt and narrow, it is desirable to join them with cement to facilitate the stitching operation and to eliminate gapping at the seams due to the relaxation of the stitching and leather after the shoe has been worn a while.

'I'he object of the present invention is, therefore, to provide an improved machine for applying cement to the out-turned beveled flange of a moccassin toe piece Without smearing the display surface, the illustrated machine being of the automatic type in that the work when placed in the machine is self-guiding and the design being such that it is rapid and efcient in operation.

In accordance with the aforesaid object, one feature of the present invention resides in the provision of coacting feeding means for gripping the flanged portion of the toe piece and moving it lengthwise through the machine, the toe piece being guided to turn in its own plane so that the ange moves in a substantially linear path during part of its movement. This is effected by the combined action of the aforesaid feeding means and a member arranged to bear against the flanged portion of the toe piece, whereby one of the feeding means which is supplied with cement coats the entire peripheral ange of the toe piece.

During the feeding movement there is a tendating feed rolls and guides necessary to accomplish peripheral movement of the toe piece;

Fig. 3 shows a front elevation of the feed rolls and guide with the toe piece shown in dotted lines;

Fig. 4 is an enlarged fragmentary view of the feed rolls gripping the ilanged portion of the toe piece; and Y Fig. 5 is a fragment of the toe piece showing the beveled edge E before and after bending.

The toe piece TP (Fig. 5) is provided with a flange E the flesh surface of which is beveled at e. Preparatory to the application of cement to the beveled surface e (Fig. 5), the ange E is premolded so that it is bent back at substantially right angles to the body of the toe Piece TP. Referring to Figs. 3 and 4, the bent back beveled flange E of the toe piece TP is shown presented to a pair of coacting feed rolls I0 and I2 constructed and arranged to grip the grain and fleshsides respectively of the flange and to move it lengthwise, the piece being caused to turn in its own plane by the combined action of the rolls I0 and i2 and an abutment I4 arranged to bear against the flange and being held from lateral movement between the rolls by a guide roll I5.

The rolls lll and I2 are mounted on a pair of shafts I8 and 20 which rotate in opposite directions so as to feed the work from right to left, as viewed in Fig. 3. The shafts I8 and 20 are mounted in the frame A of a machine of the type shown in Letters Patent of the United States No. 1,851,162, granted March 12, 1932, upon an application of J. W. Cosgrove, to which reference may be had for a description of those parts not herein more fully shown and described.

The lower shaft I8 upon which the roll I0 is mounted is journaled on an arm 22 pivoted on the frame A, the roll Iii being yieldably held by a spring (not shown) which urges the roll I0 against the work or to alimiting'position short yof the roll I2 determined by 'a stop screw 24, the

position of the stop screw being 'adjustable by the hand wheel 25. f

In the present instance the roll Ill is provided with a frustoconical surface in order to hold the flange E of the toe piece in such a position that the beveled flesh side e of the flange will lie in a horizontal plane, thereby facilitating the application of cement to that surface.

" The cement `applying roll I2v has aknurled surface and is mounted in co-operative relation with the roll Il), and, in accordance with the disclosure of the aforesaid Patent No. 1,851,162,

it is supplied with a uniform coating of cement by a roll 26 which transfers cement from a pickup roll 28 to the roll I2. The pick-up roll 28 dips in a cement pan 30 and is provided with an adjustable stripper or doctor roll 32 by which the quantity of cement transferred by the roll 28 to the roll 25 is governed.

In the present invention the grip afforded by the rolls I and I2 will not alone hold the toe piece suiliciently to provide a continuous feed as there is a tendency for the rolls to squeeze the toe piece laterally of the rolls and as a result the piece will run oli of the rolls before the entire flange has been coated unless it is held and guided by hand. It is not satisfactory tov guide the piece by hand, since that requires the close attention of the operator, and so the machine is provided with a roll I6 arranged to engage the body of the toe piece below the top of the roll I 0, as shown in Fig. 2, and on the vertical diameter therethrough to hold the piece firmly against the end face of the roll I0. The roll I6 is rotatably mounted on an approximately vertical axis so that its surface rolls along the work in the direction of movement of the same, the axle of the roll being journaled in the lower end of an arm 34 which is pivotally suspended at its opposite end from a yoke 35. The yoke is provided with a spindle 3S which is adjustably held in a split clamp 49 formed at the end of a pedestal 42, the latter being secured at its other end to the pivoted arm 22. Artooth 44 (Fig. 2) depends from the yoke 36 and forms a stop for a limit pin 4S adjustably threaded through the arm 34 for preventingv contact between the rolls I 0 and I6 when there is no work in the machine. A tension spring 48, secured at its ends to the arm 34 and the pedestal 42, yieldably urges the roll I6 toward the end face of the roll II).

The forces applied to the beveled flange E of the toe piece by the rotating rolls I0 and I2 and by the roll I6 are such as to cause the toe piece to rotate about a horizontal axis rather than to travel more or less linearly around the peripheral edge of the toe piece. In order, therefore, to overcome this rotational tendency and to provide a substantially automatic traverse around the periphery of the piece, an abutment I4 is arranged to engage the toe piece at a point to one side of thev bite of the rolls I0 and I2 and slightly above this point. The exact location of the abutment must be chosen carefully so that it will hold the side runs of the toe piece in a substantially horizontal plane (Fig. 3) during the traverse of that portion of the piece and yet will permit the whole piece to rotate about a horizontal axis as it traverses the toe piece from one side run to the other. The abutment I 4 is mounted in the chosen position and extends transversely of the rolls i0 and I2. It is fixed to a vertical plate 58 the surface of which is parallel to and substantially in the plane of the inner lateral face of the roll I0. The lower portion of the plate occupies a slot 49 formed in the end of a plate 5I adjustably mounted on the pivoted arm 22 of the machine. The head of a screw 52 threaded into the plate I locks the plate 50 in the slot. The inner surface of the plate forms an edge gage for theA edge of the turned-out flange E.

As indicated in Fig. 3, the work moves in the direction of the arrow, the rolls I0 and I2 constantly' advancing the work from right to left in a substantially linear path while the abutment I4 contacts the peripheral ange of the work prior to its passage between the rolls I0 and I2 and holds it from counterclockwise rotation about a horizontal axis during the traverse of the straight runs and permits rotation of the toe piece at the curved run around the toe. The work is introduced at the beginning of a straight run, as indicated in Fig. 3, with the grain surface in contact with the periphery and the end face of the roll I0, the edge of the beveled flange abutting the surface of the plate 50. It is evident that the position of the grain surface, that is, facing away from the cementing roll, is such that the liability for the cement to gain access to this surface is minimized. The rotation of the rolls automatically traverses the piece without manipulation by the operator, thereby coating the toe piece rapidly and efficiently.
