These machines are of a type intended. for

' use as universal cutout and marking machines, specifically. intended for-work on. shoes, leather,

and shoe materials, where the work is of,widely varying contourand design; the machines being designed to operatenot' onlynipon fiat material,

ward simplification of such mechanisms, and improvement in certain constructions going to the make up of the complete machine, such as the backing paper support and feed mechanism, adjustments in the inking roll mechanism, control of the plunger by movements of the die carriage to ether with control of the die carriage by the plunger, in the mode of attaching and looking a die in the machine, together with safety means preventing operation of the machine at all times, except when the die is accurately positioned and locked in such position, in improvements in the die carriage driving mechanism, together with certain adjustments by means of which accuracy to a fine degree in the travel of the die may be accomplished regardless of wear in the machine, and in improvements upon the automatic control means synchronizing operation of the various mechanisms.

While the present invention relates specifically to these improvements over the machine of the aforesaid patents, the general aims and objects as set forth therein are however, retained.

, Ornamenting machines for forming cutouts in a work piece, or for marking same, or for effecting both operations are of course known, but the I this machine it should be noted that the structure is readily adaptable to various types of dies and to various operations. For example, the die may be mounted to cut up or down, or in lieu of a die mounted within the machine, a self-contained auxiliary type of die and paper feed mechanism may be utilized by placement of such auxiliary unit upon the work support, which will then act to move the auxiliary unit with the work thereon toward the head of the machine, which head will function as a resistance or reaction member.

To the attainment of the foregoing and other objects, which will appear as the description proceeds, reference may be made to the accompanying drawings, in which:

Fig. 1 is a side elevation of a preferred form of machine;

Fig. 2 is a front elevation thereof;

Fig. 3 is a rear elevation of the machine base, illustrating a unit for supplying and. rewinding backing material;

' Fig. 4 is a fragmentary side elevation of the backing material unit;

Fig. 5 is a side elevation, partly in section, of the ink roll adjusting mechanism;

- and control mechanism;

Fig. 13 is a side elevation of the die holder driving mechanism;

Fig. 14 is a rear elevation thereof; and

Fig. 15 is a detail, in section, of the clutch for said driving mechanism.

Referring to the drawings, in which like reference numerals designate like parts, and with particular reference to Figs. 1, 2 and 3, there is disclosed a main frame or housing F which is carried by a sturdy base having legs 2 I, of a height to position the main frame conveniently to an operator. A work supporting plunger P is mounted in the housing for vertical reciprocation. A die holding carriage H is mounted upon a guideway comprising tracks 24-24 in the upper portion of the housing, for horizontal movement from an inoperative position at the rear of the machine to an operative position over the work support, and return, rollers 2525 being provided for the purpose. I

Power may be supplied to the machine through a constantly rotating fly-wheel pulley (not shown) which is mounted for free rotation upon a shaft S, extending through the machine. The shaft S will be connected to actuate the plunger P, and associated mechanisms, when clutched to the flywheel, by suitable clutching means C, hereinafter described. The die carriage H may be conveniently actuated by .a compact driving unit (Figs. 13, 14 and 15 and hereinafter described) mounted at the upper rear of the machine, on a shelf or. bracket 21. Suitable belt gearing (not shown) or its equivalent is provided to connect this unit to the constantly driven fly wheel pulley carried by the main shaft S.

The general structure and operation of the machine as a whole is substantially the same as described in the aforementioned patents, to which reference may be made for further description.

Pa-per feed unit It is customary to use a heavy paper or equivalent material as a backing medium beneath the work, to ensure a sharp, clean cut through the work piece, and also to protect the edges of a cutting die, and the roll of paperwhich is used is usually quite bulky, heavy and hard to handle. This paper is fed intermittently beneath the work with each operating stroke of the pressure applying plunger, thus presenting a new or smooth surface for subsequent cutouts.

As an illustration of existingpractice in this connection, reference may be made to my prior Patent No. 1,722,133 of July 23, 1929.

Figs. 3 and 4 illustrate an improved mechanism for supporting a supply roll of such paper and for rewinding. the paper into a take-up roll, as it is used.

Preferably, the paper will be supported by an idler shaft at the rear of the machine, on the legs 2| and a-run or web thereof will pass forwardly through the machine, across the work support and back to a rewinder shaft which operates intermittently, in conjunction with a step by step feed of the paper.

In Fig. 3 it will be seen that the legs 2| are reinforced or braced by a tie-rod 28, upon which is mounted a bracket 29. This bracket is also secured to the top of the legs, and provides bearings 30 for an idler shaft, formed of two parts 3l-32, connected by a knuckle joint 33, upon which shaft will be mounted a supply roll of backing paper. The short portion 32 of the shaft is rigidly secured in one bearing, and the longer portion 3|, rests in the other bearing, being held in place by a plate 34 having a spring pressed pivot 35.

At the side iofzthezbarrel 58 is an enlargement 6'0 whichhouses a pinion'meshing withthe teeth Keyed-to thezendof the: shaft 8 I outside of the "atframeronhdusirfgF: is a .link 8-3',--which in turn is 'pivoted at 84 to a second link 85' This latter link .85 is pivoted at 86 to'a'notheri lirik 81}- A stu'd 88 extending from a bracket89*on-the sideof the 73 frame F, serves to pivotally support-the link 81 outermostposition arroller- 1.8 on therside :of the to the'frame of the machine. A notcheddog 90 is pivoted at 9| to the end of the link 81.

Also pivoted to the stud 88 is a tripping lever 92 which is provided with a flange 93 cooperative with the dog 90. The tripping lever '92 has a pivotal connection with a link 94, which in turn is pivoted to the clutch lever 13. Normally the notch in the dog 90 will be in engagement with the flange 93, and it follows that as the carriage approaches its forward or outermost position to rock the shaft 8|, the clutch lever 13 will be pulled out of the path of the sliding key or wedge in the clutch C, thus coupling the constantly driven pulley to the shaft S, initiating movement of. the plunger.

As the plunger starts to rise, the bar 95 which is rigid with the plunger abuts one end of a rocker arm 96 causing a stud 91 in the other end thereof to engage the dog 90 and release same from the flange 93, whereupon the clutch lever 13 is free to I return to its original or declutching position, under influence of the spring 14.

The operation of releasing the dog 90 from the flange 93 can be effected at any time during the upward movement of the plunger, as the clutch will make a complete revolution before the shaft S will be declutched by the tapered end of the clutch lever 13, but preferably is completed within the first half of the upward stroke.

The arm 95 carries an automatic treadling lever 98, the upper end of which is normally pulled in toward the frame F by a spring 99. A rigid stud I00, adjustably mounted .in the frame F bears against the inner edge of the lever 98 and serves to limit and control the position thereof. This inner edge is formed with a cam notch IOI, and

with a dog or notched portion I02. Mounted on the rock shaft 11 is a rocking lug I03, carrying a plate or flange I04, cooperative with the notch I02. Normally the treadle lever 98 is held outwardly, free of the flange I04, by the stud I00, but as the plunger rises, the cam notch IOI is brought into coincidence with the stud and the lever is then pulled in by the spring 99 until the notch I02 engages the flange I04.

As the plunger moves downwardly the lever 98 will rock the lug I03, and the shaft 11, in effect treadling the carriage driving mechanism a second time, just as though the treadle link 15 had been actuated by an operator, thereby initiating movement of the carriage toward its return or innermost position. The notch I02 will slip ofi of the flange I04 during continued downward movement of the plunger, when the lever 98 again rides over the stud I00, whereupon the spring I05 will return the linkage to its original or normal position.

The usual braking means described in the copending cases is provided as indicated at B and is the same as in those patents except that it has been moved to the opposite end of the shaft S.

Die locking and safety latch mechanism Care should be taken, in machines of thi nature, to protect the operator from injury, by in- As best shown in Figs. 2, 9, 10 and 11, the lower face of the die carriage or holder H is formed, as heretofore, of a heavy plate H0, and the base plate III of the die is directly attached thereto, being firmly held in position by flanged lugs H2 which function to prevent springing of the die as the stripping pressures are applied to remove the work from the die. The die plate II I is provided with the usual wedge I I3 cooperating with a dovetail slot in the block I I8 and with the usual upstanding perforated securing lug I I4 which fits in the slot I I5 of the block I I0. The conventional plunger H8 actuatable by a handle at the front of the machine for clamping the wedge in the dove tail slot is also provided.

- Slidable transversely of the block H0 is the usual centering lock H1, which i mounted on a spring actuated rod H8 extending beyond the side of the block H0. A cam'shaped retractor block H9 is mounted on the outer end of the rod H8, and. is pinned to a second rod I20 extending parallel to the rod H8, but of lesser length. In the lower face of the block H0 and extending across the slot H5 is a spring pressed lug plate I2I, shown in detail in Fig. 12. This plate is guided by pins I22 and pressed normally forward by spring I23 to a position where the rod I20 is blocked by the lug against inward movement across the slot H5.

Because of the connection between the cam block H9 and the rod I20, the centering lock H1 is prevented from entering the dove tail wedge H3.

However, as a'die is slipped into the lugs H2 and the dovetail wedge I I3, the lug I I4 abuts the forward edge of the lug plate I2I, pushing it back against the springs I23 until the rod I20 is no longer blocked and is free to move inward under influence of the spring I24 which encircles the rod H8. During this inward movement the rod I20 passes through the perforation in finger I29, adjacent the cam block H9.

the lug H4, to hold the lug and hence the die tightly in position, and at the same time centering lock H1 enters the' usual notch in the dove tail wedge H3. As the cam block H9 is rigidly pinned to both the rods I20 and H8, this entire die locking mechanism will always function as a unit.

In the event that extremely heavy dies are necessary, means are provided to ensure retention of such dies against slippage or movement on the die carriage as the carriage travels back and forth. To this end two spring pressed plungers I28 may be provided at opposite sides or ends of the plate H0, controlled by eccentrics having handles I25. These handles act to position the plungers I28 either entirely within the block H0, or projecting into the die plate III, which may be perforated to receive the plungers.

In order to prevent any possibility of treadling a machine while a die is being changed, there is provided a handle I21 pinned to a rock shaft I28, which shaft extends through the frame F, terminating in an angular, tapered end or cam The cam I29 cooperates with the cam block I I9 to retract the rods H8 and I20 when it is desired to unlock or release a die, as the handle I21 is actuated.

Aspring'pressed plunger I30 rides in either one or the other of two holes in the frame at opposite ends of the stroke of the handle I21, serving to limit the extent of movement of the handle, and hold same in position.

A treadle lockmember I3I is pivoted to the frame'Eat- [32,- immediately above the 'rock'i-lug 'I6 and terminates'in a finger engageable with the lug "16 to prevent movement -ofthe -rock-shaft I1 when-soengageds A rod-I33 is pivoted -to-this locking member I3 I abve-the 1 pivot point-l 32 5 and this rod extends through the frame in proximity to the wedge or cam-block-I I9."
