4 Claims.

The present invention relates to shoe machines and more particularly to a machine forperforming a combined ink-marking and perforating operation.

For purposes of disclosure the various features of the present invention are illustrated and described as embodied in the model R machine manufactured by Western Supplies Company, under my prior patents, Nos. 1,834,919 and 1,938,678,

10 which machine has a wide use in the manufacture of shoes to perform many different operations.

Heretofore Western Supplies Company performed the combined ink-marking and perforating operation upon the well-known Western cutl51 out machine.

The principal objects of the present invention are to produce a simple, inexpensive and efficient combined ink-marking and perforating machine, particularly in the form of an attachment to the 20 model R. machine, to simplify and improve the inking means by which the marking die isprovided with ink, and to simplify andimprove the die holder, particularly, with respecttothe rev taining of the chips cut out of the work by the die and the discharge of the retained chips, and with respect to the securing of the die holder for ready removal in the machine.

To the accomplishment of these objects, and such others as may appear hereinafter, the various features of the present invention reside in certain devices, combinations and arrangements of parts hereinafter described and then: set forth broadly and in detail in the appended claims which possess advantages readily apparent to those skilled in the art.

The various features of the present invention will be readily understood from an inspectionof the accompanying drawings illustrating the best form of the invention at present known to the inventor, in which Figure 1 is a view in front elevation of the combined ink-marking and perforating machine;

Fig. 2 is a view in right side elevation;

Fig. 3 is a detail view in perspective showing 45 particularly how the work is gauged when paper is used on the metallic cutting bed;

Fig. 4 is a detail view partly in section in underside plan of the die, the die holder plate, the plunger plate and the means for securing these 50 plates together;

Fig. 5 is a detail view in sectional elevation on the line 5--5, Fig. 4;

Fig. 6 is a detail view in sectional elevation on the line 66, Fig. 4;

5 Fig. 7 is a detail view in plan of a modified Fig. 9 is a detail view in left-side sectional elevation showing the stop for limiting the downward movement of the die under the influence of the left-hand treadle.

In the embodiment of the invention illustrated in the drawings, the frame of the machine is shown as including a base 9 (Fig. 1), which is rigidly secured to a permanent horizontal support l9 mounted on legs ll. Integrally formed with the base is an irregularly shaped boss [2 constituting the work supporting bed. An overhanging arm is integrally cast with the base 9 and includes the standard l3 (Fig. 2), and the overhanging head H. In the upper parts of the standard and head is an elongated journal for the drive shaft IS. The shaft I5 is operatively connected for intermittent rotation with the pulley I5 which is driven constantly from some suitable source of power.

Between the pulley l6 and the shaft I5 is a clutch mechanism I! controlled from a foot treadle l8 through a link l9. The clutch construction is generally similar to that employed in the machinedisclosed in my prior Patent No. 1,807,952, dated June 2, 1931, which is referred to and described in my prior Patent No. 1,834,919, at page 2, lines 32 et seq. Since the construction and operation may be readily understood by reference to my prior patents, it is unnecessary to repeat the description of the construction and mode of operation of the clutch mechanism except to direct attention to the fact that the shaft I5 is operated intermittently.

The shaft l5 carries at its front end an eccentric 29 (Fig. 1), which rotates within a strap 2| having a downwardly extending arm 22. The arm 22 extends between a pair of spaced arms 23 (Fig. 2), forming upward extensions of a sliding plunger 24. A pin 25 provides a pivot connection between the arm 22 and the arms 23. The plunger 24 is mounted in a guideway formed on the front face of the head l4. A plate 26 having a rectangular cut-out portion is attached to the walls of the guideway by screws 21. A die carrier in the form of a rectangular sliding block 28 is mounted in the lower part of the guideway in axial alignment with the plunger 24.

The connection between the plunger and the die carrier is generally the same in construction and mode of operation as the connection shown in my prior Patent No. 1,938,678, so that it is unnecessary to repeat that description.

The die carrier 28 is provided with a lateral pin 29, (Fig. 9), whichslides in a curved slot 39 'formed in the left-hand side of the head 24,

This pin 29 is embraced by the When the forward end of the lever 30 is moved downwardly by the link 32, the die carrier is moved downwardly in opposition to the spring 34, (Fig. 9), which downward movement is limited by a stop pin 35, (Fig. 9), on the standard l3.

As explained in my prior Patent No. 1,834,919, the preliminary downward movement of the die carrier provides a safety mechanism preventing accident to the operatives fingers. Heretofore the cutting edge of the die was moved, during the preliminary downward movement, into engagement with the work prior to the throwing in of the clutch to drive the edge of the die through the work. In the illustrated embodiment of the present invention the downward movement of the die carrier 28'is limited by the stop pin 35 to space the cutting edge of the die slightly above the work, the space, however, being too small to receive any portion of the operatives finger.

The bottom face of the die carrier 28'is flat, (Fig. 5), to receive flatwise one face of a plate 36 provided with a pair of mutilated pins 3! which enter vertical sockets 38 formed in the die carrier 28. The plate 36 is secured to the die carrier 28 by frusto-conical surfaces 39, (Figs. 4 and 5), which engage the mutilated portions of the pins 31, respectively. The surfaces 39 are formed on elongated pins 40 mounted to slide in horizontal openings 4| formed in the die carrier 28. Each surface 39 is held in engagement with the mutilated portion of one of the pins 37 by a spring 42 coiled about a reduced portion of the pin 45 and interposed between the pin 45 and a web 43 of the die carrier 28, a screw 44 carried by the end of the pin 45 acting by engagement with the web 43 as a stop for limiting the movement of the pin under the influence of the spring. Both pins 40 are connected to a common handle 45 for operating them to release the pins 31, there being a stop 46 on the die carrier 28 for limiting the inward movement of the handle." The pins 45, adjacent the surfaces 39, are provided with a cylindrical portion 4'! of reduced diameter to permit the pins 37 to be readily withdrawn from the sockets 38 when the handle 45 is pushed inwardly.

'The plate 36 is riveted to the reduced upper ends of four posts 43 the lower reduced ends of which pass through a die block 49, a die rest plate 55), and a die holding plate 5!, the lower ends of the posts 48 being riveted to the plate 5|. The dies held by the plate 5! comprise a cut-out die 52 and a plurality of perforating tubes 53. The ink-marking die is provided with two continuous marking edges 54 and 55 formed upon a stripper plate 55 which is supported upon the lower ends of four posts 51 loosely mounted in the plates 50 and 5!. Each of the posts 51 is held from dropping out by a sleeve 58 to which the post is pinned, the sleeve 58 being mounted in a recess 59, formed in the block 49. The sleeve 58 is held normally in engagement with the plate 50 by a spring 66 coiled about the post 5! and interposed between the stripper plate 50 and the bottom of a recess 5| formed in the plate 50.

The space between the plate 36 and the block 49 is enclosed by a rectangular sheet metal wall 62 the bottom of which is secured to the four edges of the block 49 and the top of which is secured to the two narrow edges of the plate 36. The wall 62 forms a chamber 63 for retaining the chips or pills formed by the cut-out die 52 and the perforating tabs which work up from the dies into the chamber 63 through inlet passages 64 and 65, respectively. If the stripper plate post 51 were mounted in the usual manner chips or pills in the chamber 63 would prevent the stripper plate 56 from returning to its original position after each ink-marking and perforating operation. By securing the posts 51 to the sleeves 58 and by mounting the sleeves 58 in the counterbored recesses 59 all dangers of the chips or pills interfering with the proper operation of the stripper plate is obviated.

The plate 36 is provided with an outlet 66 which is normally closed by the bottom of the die carrier 28. To clear the chamber 63 of chips the handle 46 is pressed inwardly to release the pins 31 thus permitting the plate 35 and the die structure assembled therewith to be withdrawn from the die carrier 28. After the plate 36 has been separated from the bottom of. the die carrier 28, the die structure may be turned into an upside down position whereupon the chips or pills in the chamber 55 may be shaken out through the outlet 66.

In some cases, it may be desirable to support the work upon a fiat plate 61, (Fig. 7) constituting the cutting bed, supported removably upon the flat upper surface of the work supporting bed l2. To this end the bed I2 is provided with four upstanding pins 68 which are received by four openings 69 formed in the plate 61. The work may be gauged by an abutment gauge plate removably mounted upon the plate 51. To this end the plate H! is provided with two holes H which receive pins 12 projecting from the bed l2 through suitable openings formed in the work supporting plate 61.

In other'cases it may be desirable to support the work upon a sheet of paper 13 which is fed over the work supporting plate 61 between the pins' 68. When the paper is employed as the normal cutting bed a gauge plate 14, (Fig. 3), is used. This plate 14 is provided with openings which receive pins 15 projecting upwardly from the upper surface of the plate 6'! outside the path of the paper 13. a In the illustrated embodiment of the invention the gauges 6'! and M are shaped to engage the throat ll of ,a vamp 18, but it will be understood that these gauges may be shaped to engage selected edges of any shoe upper part upon which it is desired to'perform the combined ink-marking and perforating operation.

As usual in this class of machines in which paper is employed as the normal cutting bed, the paper is mounted in a roll 19, is conducted over the surface of the abnormal cutting bed 67 and is rerolled upon a rewind roll 80. The paper is fed a step, either at the beginning or at the end of a cycle, when the clutch mechanism I! is thrown into operation, by the rolls 8| and 82. The roll 81 is rotated'intermittently by a ratchet 83 of the roller type which is driven by the lower end of a lever 84 the upper end of which is provided with a roll 85, which engages a cam surface 86 formed on the clutch hub. The rewind roll 80 is driven by a belt 81 which passes over a pulley 88 On the rewind roll shaft and a pulley 89 constituting the hub of either the pulley IE or the fly wheel therefor. The belt 81 is not tight so that it may constantly slip over the pulley 89, thus keeping the paper wound tight on the rewind roll notwithstanding variations in the diameter thereof. 7

The marking edges 54 and 55 are inked by an ink pad 95, (Figs. 3 and '7), which is mounted in a shallow pan S II- The opposite sides of the pan are provided with blocks 92 the lower edges 15 gagement in the manner illustrated in Figs. 3

and 8 by a coiled spring 05 one end of which is secured to the tray 9| and the other end of which is secured to the carriage 94.

The front and rear faces of the carriage 94 are each provided with a channel 96 which receives a rail 97 secured, respectively, to the front and rear faces of the work supporting bed I2. The carriage slides on the rails 91 to interpose the ink pad 00 between the work mounted on the work support and the combined ink-marking and perforating die.

The carriage 94 is provided with an operating handle 99 by means of which the operative slides the carriage to bring the ink pad 00 beneath the die and to return the carriage to the position of Fig. 3. In order to elevate the ink pad vertically into engagement with the marking edges 54 and 55, the tray 0! is provided with an angle plate I00 the vertical face of which engages the left-hand wall of the work supporting bed I2, viewing Fig. 3, just as the ink pad 90 is brought beneath the die thus stopping the tray and causing the blocks 93 to slide beneath the blocks 92 thereby elevating the ink pad 90 into engagement with the marking edges 54 and 55. When the carriage 94 is returned to the position of Fig. 3 the springs 95 lower the ink pad by sliding the blocks 02 down the inclined surfaces on the blocks 93.

The carriage 94 may be slid back and forth and the ink pad elevated into engagement with the marking edges 54 and 55 by a different type of operating handle IOI illustrated in Figs. 7 and 8.

The handle IOI comprises two parts, the part I02 being a rigid bar projecting forwardly from the carriage 94 and the part I03 being a lever pivoted to the part I02 and the tray 9|. The bar I02 and the lever I 03 are maintained normally separated by a coiled spring I04 one end of which is engaged with the lever I03 and the other end of which is received in a recess I05 formed in the bar.

With this construction, the handle IOI may -be grasped to slide the carriage 94 over the work support to position the ink pad 90 directly beneath the marking edges 54 and 55 whereupon the bar I02 and the lever I03 may be squeezed to operate the lever I03 and slide the tray 9| to the left, (Fig. 7). During this sliding movement of the tray 9|, the blocks 02 ride up the inclined surfaces on the blocks 93 thus elevating the ink pad 90 into engagement with the marking edges 54 and 55.

In operating the machine, the marking edges 54 and 55 are inked by moving the ink pad 90 in two directions normal to each other, the movement in one direction being horizontal to interpose the ink pad between the work support and the combined ink-marking and perforating die, and the movement in the other direction being vertical to bring the ink pad into engagement with the marking edges 54 and 55. After the ink pad 90 has been returned to its normal position disaligned from the work support, the operative locates the work on the plate 61 against the gauge I0 if no paper is used or on the paper I3 against the gauge I4 when paper is used.

After the work has been gauged the operative steps on the treadle 32 and brings the die down toward the work the stop 35 limiting this movement when the marking edges 54 and 55 are spaced about A" above the work. This small spacing insures the retention in the machine of the safety feature inherent in Model R machines while preventing blurring of the work which might occur should the marking edges 54 and 55 engage the work during the preliminary downward movement of the die. The operative then steps on the treadle I8 to throw in the power mechanism for moving the die downwardly to perform the combined ink-marking and perforating operation.

In some cases it may be desirable to move the marking edges 54 and 55 downwardly through the treadle 32 into engagement with the ink pad after it has been interposed between the die and the work support.

What is claimed as new, is:

l. A combined ink-marking and perforating machine having, in combination, a marking die, a work support, means for relatively operating the die and the work support to mark the work, a carriage interposable manually between the marking die and the work support, and means carried by the carriage and movable vertically automatically thereon in a direction away from the work support and towards the marking die for: depositing marking material thereon.
