83,796. Divided and this application April 11,

24 Claims. (Cl. 101-316) This invention relates to ornamenting machines for use in the manufacture of boots and shoes, wherein is provided an ornamenting die operable upon the work. The present application is a division of a (1o-pending application, Serial No. 83,796, filed June 5, 1936, and is primarily directed to improvements in a die carriage operating mechanism and controls for said mechanism, and for mechanisms related thereto.

These features provide improvements in combined marking and cutting machines adapted for operations upon skins, upper blanks, tted or closed uppers, and the like, in which the work is marked with ink, pigment, or its equivalent, as part of a cycle of operations, during which an ornamental design is perforated or cut therein.

Devices and machines of this type are described and claimed in the patents of Benjamin W. Freeman, No. 2,084,335, dated June 22, 1937, and Benjamin W. Freeman et al. Reissue 20,294, dated March 16, 193'?, both of which were copending with the aforesaid application.

These machines are of a type intended for use as universal cutout and marking machines,

specically intended for work on shoes, leather,

and shoe materials, where the work is of widely varying contour and design, the machines being designed to operate, not only upon at material, but also to perform operations on other than flat work, such as closed and fitted uppers orother types of ring-like work.

Objects of the invention include the formation of ornamental designs in the work, by the application of a stamped or printed marking which may simulate stitching, or may take the form of a design, or by the formation of ornamental cutouts in the work, or by combinations of both markings and perforations or cutouts; and the accomplishment of the marking and cutting operations either simultaneously or during a continuous cycle of operations.

Reference to stamped or printed markings is.

made herein because of its universal adaptation to all types of leather; however, the present invention is likewise readily adaptable to the production of other forms of marking, e. g., impression or indentation of the work. It is a further object herein to provide means for changing from one form of marking to another by a slight adjustment, and without necessitating change of any part of the machine.

A still further object contemplates the application of markings which may be used as a guide for subsequent operations on the shoe parts, such as aligning the parts relative to each other,

stitching, etc., the markings being applied at such a time and in such a location with reference to the cutouts as to insure accuracy in the subsequent operations with relation to the cutout portions of the work.

Itis contemplated further that the marking device may be combined with or form a part of the conventional vstripper plate which is normally designed for stripping the work from the cutting edges of the die.

Various safety mechanisms assuring a predetermined cycle of operations, and designed to prevent injury to an operator or to the work by preventing premature, delayed or inaccurate operations form a feature of this invention.

As described in the aforesaid copending applications, and illustrated herein, a preferred embodiment of the machine has a power driven plunger movable through a relatively vertical plane, the plunger serving to mount a work support on which the work may be accurately positioned by means of suitable gaging devices.

A die which is relatively fixed insofar as vertical movement toward the work supporting plunger is provided, and this die is arranged to move into and out of an operative relation to the plunger, the movements however, being confined to a substantially horizontal plane in the illustrated embodiment. Means are also provided for retaining the die against movement in any direction should it be desired to so operate the machine.

A backing medium of paper or its equivalent may be provided between the work and the support, and the gaging devices may be carried by the work support, by the die, or otherwise interposed between the work supporting surface and the die.

A single control, as a treadle or its equivalent, is preferably utilized for the mechanism by means of which the die may be moved into an operating position, the marking elements of the die inked, the main clutch of the machine released, the work support and plunger raised to effect an operation on the work, and return, and the die thereafter moved to a position away from an operator who may then remove the work from the machine.

The broad principles and mechanisms for accomplishing these several results under a single control are illustrated in the aforesaid patents, and the improvements herein described aim toward 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 together with control of the die carriage by the plunger, in the mode of attaching and locking 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 present machine is designed to meet increasing demands of work and operating pressures without increasing the size of the machine itself to an impractical degree.

In commenting upon the universal features of 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 aecompanying drawings, in which:

Fig. 14 is a rear elevation thereof; and

Fig. l5 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|, 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 25--25 being provided for the purpose.

Power may be supplied to the machine through a constantly rotating ily-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 fly wheel, 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 27. 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.

Paper 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 paper which 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 existing practice 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 2l 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 3l, rests in the other bearing, being held in place by a plate 34 having a spring pressed pivot 35. With this construction, the long end 3l of the idler shaft may be raised from the bearing to permit placement thereon of a fresh roll of paper, without in any manner disturbing the rigidly secured short end 32.

A rewinder shaft similar in construction to the idler shaft and formed of two sections 36--31 connected together by a knuckle joint 38, is supported by bearings 39-39. The short section 31 extends through a hexagonal bushing 40, which is rigidly secured by a set screw 4| in one bearing, and the longer section 36 extends through a similar hexagonal bushing 42 secured by a set screw 43.

A pulley 44, suitably belted to the driving mechanism of the machine, is secured to the outer end of the short portion 31. In operation the driving belt will normally slip on the pulley 44 until the paper feed mechanism (not shown) becomes operative, whereupon tension on the paper being relieved, the pulley will rot-ate, and thus at all times, tend to keep the web of paper free of slack and rewound.

To remove a roll of paper, the set screw 43 will be released and the long or handle end 36 of the rewinder shaft may be removed from its bearing. A collar 45 cooperating with an angle 46 serves to prevent endwise slippage of the rewinder shaft when changing rolls, and collars 41-41 serve to prevent endwise slippage of the paper roll on the shaft as well as to guide the rewinding thereof.

Ink roll adjustment mechanism The mechanism for applying ink or equivalent marking medium to the marking element is best illustrated in Figs. 5 and 6 and as shown is practically the same as that illustrated in the Freeman et al. Patent Re. 20,294, except for certain:Y

adjusting means.

Generally speaking, the ink applying unit comprises an inking roll 5| carried on a rotatable shaft 52 which is preferably, but not necessarily driven, this shaft being resiliently and adjustably mounted in a pair of brackets 53. Inasmuch as it may be found desirable to ink the die, only during its movement to working position, the brackets 53 are pinned to a rock shaft 54 so that the roll 5| may be raised into the path of movement of the die, and thereafter restored to its original or normal position out of such path. An idler or distributing roll 55 may be provided to insure even distribution of the marking medium on the roll 5|.

Conditions occur, however, in which too much or too little ink may -be supplied by the roll 5|, and hence it becomes important that the position of the roll with relation to the marking edges of the die be made adjustable, such that the proper amount of ink will always be supplied to the marking die.

In my previous patents the projecting ends 56 of the brackets 53 were directly connected to a cam actuated lever such as the lever 51, which, through the cam, synchronized rocking movement of the brackets on the rock shaft with movements of the die. In the present instance, an adjusting means is interposed between the cam actuated lever and the brackets, this adjustment comprising a barrel 58, within which reciprocates a rack plunger 59. The barrel is pivotally connected to the end of one bracket 56 and the plunger is pivotally connected to the end of the cam actuated lever 51.

At the side of the barrel 58 is an enlargement 60 which houses a pinion meshing with the teeth of the rack plunger. A control shaft 6|, keyed to the pinion, extends from the housing 60 to an accessible point on the machine, and terminates in a handle 62. Cooperative with the handle is an index plate 63 which is perforated in a conventional manner as at 64 to receive a spring pressed pin 65 in the handle 62.

Obviously, angular movement of the handle along the plate 63, will rotate the pinion in the housing 60 and will produce a corresponding movement of the rack plunger 59, thereby varying the distance between the lever 51 and the bracket 56. A knuckle joint 66 is provided in the shaft 6| fto accommodate angular movements of the housing 58 and the shaft may also be provided with collars 61-61 to prevent endwise slippage. This arrangement is effective to adjust the normal position of the roll 5I with respect to the die and consequently will result in the application of more or less ink to the die in 'accordance with the adjustment.

Plunger and die carriage control The improved arrangement for controlling op eration of the'plunger P by the die carriage H path of a sliding clutch key or Wedge (not shown) which is spring pressed to traverse the groove. When this lever 13 is pulled out of the path of the sliding key as hereinafter described, then the key or wedge will slide freely into a coupling engagement with the pulley. For a more complete description of this type of clutch, reference may be made to my aforesaid copending case.

Control of the machine is generally effected by the following mechanism. A treadle link 15 is connected to a rocking lug 16 which is pinned to a rock shaft 11 and effective thereby to set into operation the carriage driving mechanism shown in Figs. l2 and 14. All of this mechanism including the carriage drive is generally the same as that of the Freeman et al. Patent Re. 20,294, except that a roller type of clutch has been substituted in the driving mechanism, in lieu of the sliding key type of clutch described in that paten f As this mechanism is set in operation the carriage H moves forward from its position of rest at the rear, and as it approaches the forward or outermost position a roller 18 on the side of thel carriage rides along a cam arm 19, to engage a cam 60 carried thereby (Figs. '1 and 8). One end of the arm 19 is pinned to or integral with a rock shaft 8| which extends through the side of the frame F, and it will be evident that as they roller 18 engages the cam 86, the arm 19 will be depressed, thereby rocking the shaft 8|. justing means 82 may be provided for properly positioning the cam along the arm 19.

Keyed to the end of the shaft 8| outside of the frame or housing F is a link 83, which in turn is pivoted at 84 to a second link 85. This latter link 85 is pivoted at 86 to another link 81. A stud 88 extending from a bracket 69 on the side of the frame F, serves to pivotally support the link 81 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 inthe 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 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 l 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 |00, 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 |0|, and with a dog or notched portion 02. Mounted on the rock shaft 11 is a rocking lug |03, carrying a plate or flange |04, cooperative with the notch |02. Normally the treadle lever 98 is held outwardly, free of the flange |04, by the stud |00, but as the plunger rises, the cam notch |0| is brought into coincidence with the stud and the lever is then pulled in by the spring 99 until the notch |02 engages the flange |04.

As the plunger moves downwardly the lever 98 will rock the lug |03, 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 |02 will slip oi of the flange |04 during continued downward movement of the plunger, when the lever 98 again rides over the stud |00, whereupon the spring |'0'5 will return the linkage to its original or normal position.

'Ihe usual braking means described in the aforesaid patents 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 this nature, to protect the operator from injury, by inadvertent operation of the various moving parts, when changing a die, which necessitates placing the hands in the machine. Also it is important that the die be at all times securely held in accurate position on its holder or carriage. My Patent No. 1,990,597, granted February 12, 1936, discloses means for securing the die in place, and for locking the machine when the die is changed, and the present invention adopts the broad principles therein disclosed.

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 ||0, and

the base plate of the die is directly attached thereto, being firmly held in position by anged lugs ||2 which function to prevent springing of the die as the stripping pressures are applied to remove the work from the die. The die plate is provided with the usual wedge |3 cooperating with a dovetail slot in the block |0 and with the usual upstanding perforated securing lug ||4 which ts in the slot ||5 of the block H0. The conventional plunger ||6 actuatable by a handle at the front of the machine for clamping the wedge in the dovetail slot is also provided.

Slidable transversely of the block |0 is the f usual centering lock ||1, which is mounted on a spring actuated rod H8' extending beyond the side of the block ||0. A cam shaped retractor block ||9 is mounted on the outer end of the rod |'|8, and is pinned to a second rod |20 extending parallel to the rod H8, but of lesser length. In the lower face of the block ||0 andy extending across the slot ||5 is a spring pressed lug plate |2|, shown in detail in Fig. 12. This plate is guided by pins |22 and pressed normally forward by spring |23 to a position where the rod |20 is blocked by the lug against inward movement across the slot l5.

Because of the connection between the cam block I I9 and the rod`- |20, the centering lock ||1 `is prevented from entering the dovetail wedge H3.v However, as a die is slipped into the lugs ||2 and the dovetail wedge ||3, the lug ||4 abutsthe forward edge of the lug plate |2 I, pushing it back against the springs |23 until the rod |20 is no longer blocked and is free to move inward under influence of the spring |24 which encircles the rod IIB. During this inward movement the rod |20 passes through the perforation in the lug ||4,to hold the lug and hence the die tightly in position, and at the same time centering lock ||1 enters the usual notch in the dovetail Wedge H3. As the cam block IIS is rigidly pinned to both the rods |20 and ||8, this entire die locking mechanism will always function as a unit.

In the event that extremity 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 |29 may be provided at opposite sides or ends of the plate I0, controlled by eccentries having handles |25. These handles act to position the plungers |26 either entirely within the block 0, or projecting into the die'plate 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 |21 pinned to a rock shaft |28, which shaft extends through the frame F, terminating in an angular, tapered end or cam finger |29, adjacent the cam block I9. The cam |29 cooperates with the cam block ||9 to retractthe rods ||8 and |20 when it is desired to unlock or release a die, as the handle |21 is actuated.

A spring pressed plunger |30 rides in either one or the other of two holes in the frame at opposite ends of the stroke of the handle |21, serving to limit the extent of movement of the handle, and hold same in position.

A treadle lock member |3| is pivoted to the frame F at |32, immediately above the rock lug 18, and terminates in a finger engageable with the lug 16 to prevent movement of the rock shaft 11 when so engaged. A rod |33 is pivoted to this locking member I 3 l, above the pivot point |32, and this rod extends through the frame in proximity to the wedge or cam block II9. As the block ||9 moves outwardly, under influence of the cam |29, the rod |33 is consequently pushed outwardly depressing the lock member |3| until it engages the lug 1B thus rendering it impossible to treadle the machine.

On the other hand, when the wedge block H9 moves inwardly, a spring pressed plunger |34 mounted below the pivot point |32 will restore the lock |3| to normal position.

The stripping mechanism and means for applying stripping pressure is substantially the same as in vFreeman et al. Patent Re. 20,294, except that the posts which engage the stripper pressure plate |38 have been improved by the addition of a bar |31 connecting the posts at each side of the plunger.

The bars may be rubber surfaced to absorb minor shocks as the stripper pressure plate |38 is engaged.

Dz'e holder driving mechanism The improved driving mechanism for the die holder or carriage H, is best illustrated in Figs. l

1, 13, 14 and 15. This mechanism is mounted on a bracket 21 at the rear of the machine and consists of' gearing and clutch mechanism actuatable under control of the shaft 11, and driven conveniently from the main y wheel pulley. A link |4| is pinned to the shaft 11 and in turn yoked or pivoted at |42 to a connecting link |43 which is pivoted at |44 to a crank arm |45. The other end of the arm |45 is connected to a clutch actuating link |46, which through engagement with a clutch control lever |41 is ef- `fective to remove the clutch stop |48 from the path of a block secured to the clutch tumbler |49. As this occurs, the spring |50 moves the clutch tumbler forward to cause a wedging engagement between the rollers of the clutch and the clutch hub, in a well known manner, whereupon'the carriage H will be driven forwardly. To insure operation of the roller clutch through a second revolution to return the carriage a dual cam I5I is provided as heretofore.

There is a possibility that the clutch release mechanism |41, through poor adjustment or wear, might not release the clutch at the proper time, and to prevent any such occurrence and to ensure positive action, the cam driving gear |52 is provided with rollers ISS-|53, on opposite sides of the latch or locking portion of the clutch release mechanism. It follows that as the gear rotates, these rollers will engage the latch or locking portion of the clutch release and hold same in its unlocked position. The usual braking means are of course provided to bring the parts toV rest in a proper manner.

It is essential-that the carriage comes to a stop in a predetermined position at the front of the machine, in alignment with the work support, and occasionally adjustment of this posi.

tion to a fine degree is necessary. Adjustment of the tumblers of the clutch can be made relative to the clutch stop |48 through the medium of a flat spring |54, adjustably mounted in the frame or bracket -at the rear of the machine. The upper end of the spring |54 is secured to the clutch hub. The stop |48 is made similarly adjustable and a fine degree of adjustment can be obtained by relative manipulation of these two elements.

Having thus described the invention the operachine awayfrom the operator, and the work table or plunger P in its lowermost position, the main ny wheel pulley of course continuously rotating. Work may be placed on the plunger and, by suitable gage means, accurately aligned with the outermost or operating position ofthe die. Then through depression of thetreadleconnected to the link 15, the machine is caused to operate, the die carriage H moves forwardly, trips the plunger control, and the plunger rises to strike a hammer-like blow against the die, which has by this time reached a position of rest forwardly over the plunger. While striking the blow the stripper control posts carrying the bars |31y will have raised the stripper pressure plate |38.

As the plunger returns to its original position it trips the die carriage mechanism, and the die carriage recedes to the rear of the machine, the plate |38 in the meantime having acted through the stripping mechanism to strip the work'from the die. The marking elements will have been inked on the forward stroke of the die carriage through the medium of the inking mechanism shown in Figs. 5 and 6.

With the arrangement of controls rfor the die carriage and actuating mechanism as de` scribed, it is possible to operate the plunger and carriage in synchronized relation, to operate either to the exclusion of the other or to operate the carriage through half of a complete stroke, i. e., outwardly to a forward position and stop, or inwardly to a rear positionand stop, either alone or in conjunction with the plunger movement. It is further evident that the machine is designed for cutting, or marking per se, or in combination. v

Application of or removal of heavy rolls of backing paper are facilitated.

Adjustments in the inking roll mechanism may be made handily to obtain an exact application of the proper amount of ink or marking medium to the marking elements of the die. The die locking mechanism not only provides means for holding the die securely in position, but'also renders the machine impossible of operation during such time as the die may be out of position, for removal or replacement.

The entire construction herein described, is intended to be foolproof and thev machine operations so simplified, safe and automatic as to make it possible for a relatively inexperienced operator to operate the machine without diculty and in a safe manner. j
