- Renewed November 6, 1934 25 Claim.

This invention relates to shoe omamenting machinery and more particularly to combined marking and cutting machines adapted for operation upon skins, upper blanks, fitted or closed uppers and the like, in which the work is marked with ink or the like at the same time, or as part of the cycle of operations during which the work is also ornamented by perforating or cutting out a design therein.

Among the objects of the invention are 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, by the production of ornamental cutouts in the work, or by combinations of both,

and in marking and cutting simultaneously, or during a continuous cycle of operations.

Another object contemplates the application of markings to 'the work which may be used as a guide for subsequent operations, such as stitching, or aligning of the shoe parts with respect to the marked part.

Still another object resides in the provision of a marking device which will function as a stripper in addition to its marking functions or a. stripper arranged to function as a marking device in addition to its work stripping fuctions.

Various safety mechanism ensuring a predetermined cycle of operations and designed to prevent injury to an operator or to the work by preventing premature cutting operations form a feature of this invention.

A further object contemplates the provision of a. machine in which the work may be supported by either a fiat bed or by an anvil adapted to properly hold ring like work, such as closed and fitted uppers.

To the attainment of the above, and other objects which will appear as the description proceeds, reference may be made to the accompanying drawings, in which Fig. 1 represents a front elevation of the machine;

Fig. 2 is a side elevation thereof;

Fig. 3 is a plan view of the work table;

Fig. 4 is a front elevation of the table;

Fig. 5 is a plan of the work supporting and positioning member;

Fig. 6 is a front elevation of the die unit;

Fig. 7 is a detail of the die unit;

Fig. 8 is a plan view of the die unit looking upward in Fig.6; and

Fig. 9 is an enlarged detail section of the work supporting and position member illustrating a modification of one of the marking dies of Fig. 6.

In a preferred embodiment of the invention illustrated herein there is disclosed a machine having a power driven plunger cooperating with a. die unit (in the present embodiment the die is mounted on the plunger for movement therewith, although such die might readily be mounted independently of the plunger) and a work support on which the work is positioned, with a. backing member of paper or its equivalent between the work and the support. In order to properly align, gauge and position the work, abutments are located on the work support although, a movable gauging mask might readily be utilized either in conjunction with, or in lieu of such an abutment.

Referring more specifically to the drawings, in which like reference numerals designate like parts, it will be observed that the machine comprises generally a base 10, supporting an upwardly extending frame or casing 11 within which are housed most of the movable operating parts. The head 24 of the frame 11 overhangs the forward portion of the base 10, on which portion is mounted an upright, anvil-like support 12. A pair of guide rails 13 and 14 are attached to the base and are braced by struts 23, and upon which guides, a carriage or work table 15 is mounted for sliding movement. The running surface of the guide 13 is V-shaped, the carriage 15 being provided with a pair of correspondingly shaped rolls 16, and the guide 14 is formed with a T-shaped running surface, the carriage being provided with a pair of flat surfaced rolls 1'7 cooperative therewith. Removably attached to the table 15 is a work supporting and positioning plate 18. Positioning pins 19 extend from the upper face of the table, the plate 18 having holes 20 for cooperation therewith. When the plate and table are assembled, the openings 20 will be aligned with the pins 19 and the plate located and held thereby.

Openings 67 are formed in the plate 18, through which the cutting edges of the die may pass. The openings may be of such a size as to not only permit passage of the cutting edges of the die therethrough, but also of such extent that the portion of the work to be marked may lie within the opening with the remainder of the work lying substantially flat on top of the supporting plate 18. The plate 18 will be made as thin as possible so that the work will not be depressed into the area 6'7 any more than is necessary. If desired either or both of the marking dies 38 and 39 may be made in two or more parts, operating independently at different levels (at the time that the marking of the work takes place) to mark a portion of the work in the depressed area 67 and also to mark an adjacent portion of the work which is not depressed, as indicated in Fig. 9.

The top of the support 12 may be provided with a sheet of brass to protect the cutting edges of the die and above this is mounted a sheet of paper 68, which is movable between a roll 69 located in the base of the machine and another roll 89' mounted adjacent the machine frame. The purpose of the paper or backing strip 68 is to contact with the cutting edges as they pass through the work to ensure clean cutting. The operating mechanism at the left of Fig. 1, and manner of feeding the paper are substantially the same as described in a co-pending application Serial No. 515,346, filed February 12th, 1931.

With the work W (indicated as two quarters), positioned and held on the plate 18, by means of a locating abutment 70 and spring clamps 71, the under portion of the work will occasionally strike the paper backing as the table is moved back and forward, the paper backing not being shiftable with the table. This will not happen often, but in order to prevent such occurrence the openings 67 may be covered with a thin piece of tough material, which being fastened to the plate will prevent any frictional contact between the work and the paper backing during the movement of the table or feed of the paper, if the work happens to be above the paper at that time. When the die comes down it will cut through the work and openings into this piece of material, and it is only through these openings that there can be any contact between the work and the paper backing (or top of the support 12 in case no paper is used). The contacting surface is therefore reduced to a minimum, and to such a small extent that it will susbtantially eliminate any frictional contact sufficient to cause move ment of the work out of position, when the table is moved from work placing to work cutting position.

The table 15 and plate 18 are jointly movable from a position beneath the overhanging head 24, outwardly to an exposed location where they are freely accessible to the operator. Movement of the table may be eifected manually, as shown in Patent No. 1,681,033, or may be effected by the application of power suitably applied, an illustration thereof, being found in Reissue Patent No. 18,162 of August 25th, 1931.

Within the head 24 is mounted, for reciprocating movement, a plunger 25. This plunger is actuated by means of an arm 26 connected to a power shaft 28 which in turn may be connected by a single revolution clutch 29 toa continuously driven pulley 30, which serves as a means for supplying power to the machine. When the clutch 29 is operated, in a manner hereinafter described, to connect the pulley 30 and shaft 28, the shaft 28 will make one revolution, causing the plunger 25 to descend once and return, after which the plunger will remain in its inoperative position until the clutch is again actuated.

Attached to the plunger is a master die holder 32 carrying a pair of dies 33 and 34, which as illustrated, include a series of perforating or cutting tubes 35 supported by a die block or base member 36 detachably mounted in the master die holder 32. Supported in advance of the dies 33 and 34, respectively, are marking dies 38 and 39.

The marking dies are resiliently mounted on the block 36 by means of pins 31 which extend through openings 41 in the cutting dies as and 34, springs 37 serving to normally space the marking dies in advance of thecutting dies. A small cup-shaped collar 31' encircles each pin 31, and the pin 31 is held in position in its downward movement by means of a small pin 31 which is inserted in the pin 31 and enclosed within the cup-shaped portion of the collar. The spring 37 is located between the upper face of the cup-shaped collar and the block 36.

Referring particularly to Fig. 9 wherein is illustrated a marking die constructed to operate on work extending through different planes, it will be observed that either of the marking dies may be made in two-parts, 39' and 39. The portion 39 is illustrated as mounted over the depression 67, while the portion 39' will be eifective to engage a part of the work not located over a depression.

The master die block is removably attached to the plunger head by means of a dovetail rib 40 arranged to slide in a correspondingly shaped groove in the face of the plunger. Extending forwardly from this groove, through the plunger, is a shaft 42 having a handle 43 on its outer end and a cam 44 on its inner end. When the holder is to be attached to the plunger, the rib 40 is placed in its groove and the cam shaft 42 partially rotated to wedge the rib in the slot, thus maintaining the holder rigidly in position.

The die block 36 is attached to the master die holder by means of a pin 45 having a vshaped side face, and fitting into an opening of the holder, a cam shaft 47 having a manipulating handle 48 being provided for locking cooperation with the pin 45. A smaller pin 49 is also mounted on the block 36 and engages a hole in the holder, the pins 49 and 45 conjointly serving to locate and align the block with respect to the holder, the pin 45 additionally serving, through its coaction with the lever 47, to lock the base or block 36 in its aligned position.

It should be observed that the base 36, the cutting or perforating dies 33-34 and the marking dies 38-39 form a unit which may be replaced in the holder 32 by other dies, to provide variations in the patterns and ornamentation which are to be applied to a shoe. While the unit illustrated comprises a pair of right and left dies, it may be desirable to have a single pattern extending from one side to the other rather than a pair of right and left dies.

The marking dies 38 and 39 being mounted in advance of the cutting edges may have ink or other ornamenting material applied thereto such as colored pigment, gold or silver leaf, etc., by any suitable means such as a hand pad, ink rollers or otherwise. In the present embodiment there is illustrated a movable roller 51 connected at its end to a pair of rack bars 52 arranged to be driven by gear segments 53 through the medium of a pulley 54. This pulley is connected to and continuously rotated by the pulley 30.

A single revolution clutch 55 similar to clutch 29 is arranged to connect the pulley 54 to a shaft 56 which, through suitable linkage, will actuate the segments 53 to produce a single forward movement, of the rack bars and the roll past the marking dies 3839 and back, applying the marking medium to the dies.

Extending from the table '15 is a plate or finger 58 positioned to engage and control a clutch lock mechanism 59 which in turn controls a clutch key 60 adapted, in one position to prevent actuation of the clutch 55 and in another position to release the clutch whereby the pulley 54 may be connected to the shaft 56. The clutch itself is actuated by means of a treadle rod 61.

The segments 53 arekeyed to a shaft 62 on which is keyed an arm or lever 63. This arm is so located that as the segments reach a position in which they have fully retracted the ink roll 51 after an inking operation, the end of the arm 63 will engage a clutch lock mechanism 64 which controls a clutch key 65 adapted in one position to prevent actuation of the clutch 29 and in another position to release the'clutch whereby the pulley 30 may be connected to the shaft 28. The clutch itself may be actuated by means of a foot treadle rod (not shown) or may be arranged to automatically connect. the pulley and shaft upon release by its key 65, the essential feature of this mechanism being, that the shaft 28 cannot be actuated by the continuously rotating pulley 30 until after the inking mechanism has completed its work and has been retracted, it being further observed that the inking mechanism cannot be actuated until the carriage. 15 has been locatedin operating position beneath the plunger and dies, which 10- cating operation serves through the finger 58 to release the clutch 55.

Reference may be made to a co-pending application, Serial No. 478,264, filed .August 27th, 1930, for a more complete description of the clutch arrangements and the operating mechanism for driving the plunger and ink roll, only such details as are essential, being described herein.

The positioning or work supporting plate 18, as illustrated is made to support fiat work and the embodiment of machine herein is designed especially to perform an ink marking and cutout operation on flat work. However, thesupport 12 is in the form of an anvil and obviously by use of a different style of work table 15 and plate 18 could be readily adapted to cutout and mark fitted work. As an example, a work support of the general shape illustrated in the above mentioned application or patent might readily be substituted for the one illustrated herein, and it is contemplated that this machine may use a work support having top surfaces of any desired size, area and shape necessary to accommodate same. to a particular blank whether flat work or of the fitted upper type.

It is desirable that the work table be accurately held in position relative to the'die and to accomplish this there is provided a block 72 on the work table which acts as an abutment fora lever 73, which presses against the block and clamps r tached to the lower side of the plunger 25 moves down, the pin 74 which is resiliently mounted on the plunger alsomoves down; this pin is constantly in contact with a lever 75, mounted on a shaft 76 extending through the frame and the other end of which supports the lever- 73. It will therefore be obvious that as the die moves downwardly the pin 74 depresses the lever 75 which in turn moves the lever '73 against the abutment 72. When the die reaches a position approximately a quarter of an inch above the work, the work table will be locked in position and will remain in that position until the die comes back up about a quarter of an inch from the work. During If, instead of using a positioning plate. 18, a

mask or gauge such win my application Ser. No. 478,264 is used, then a die positioning and locking mechanism as just described may be omitted. The abutment 72 and its coacting lever 73 are so shaped that if wear takes place in any of the parts or the operator fails to move'the table all the way back, the abutment and lever -will move the work holder into its proper position and in that position will hold it until the work has been marked and 'cut out.

From the foregoing description the operation of the machine will be readily apparent. With the table in its outer position and removed from beneath the die the work is placed in proper position, and the table then pushed inward.- The inward movement of the table unlocks the clutch 55 and the operator can then actuate the treadle rod 58 which will connect the gear segments 53 to the continuously driven pulley 54. The ink roll is thus moved forward and retracted to ink the marking edges of the die 38 and 39. Should the operator's fingers for any reason be underneath thedie at this time the forward movement of the ink roll will push them aside, in fact if desired a guard may be placed in advance of the roll for the sole purpose of sweeping away any obstruction which might happen to come between and the cutting or perforating dies will follow,

on continued downward movement of the plunger, passing through suitable openings, illustrated in Fig. 8 as the space between the marking ribs 46, to cut out the desired ornamental pattem; Just before the marking die reaches the work, lever 73 and abutment 72 will coact to lock the work table accurately in position.

The upward movement of the plunger completes a cycle of operations and the table may be again drawn outwardly for the insertion of a new piece of work.

On upward movement of the plunger which acts to draw the dies from the work, the cutting die will first be withdrawn from the work, the springs 37 serving to hold the marking plate against the work. The marking plate thus will function as a stripper for the cutting dies in addition to its primary function of placing a marking on the work.

An advantage in the die structure, above described, and wherein the markeris resiliently mounted, resides in the fact that need for adjustment of tlie marker is eliminated, inasmuch as need for pressure in marking is eliminated, this being due to the fact that no indentation as such is necessarily made in the work. Too much prestype is usually provided with a rubber backing eii'ective to distribute the pressure evenly. It is impossible to handle various thicknesses of lather. under such conditions, because it such am np risadiustedtoindentathickpieceoi lather, then insumcient pressure would be had toindentathinpiece, Ontheotherhandiithe markerisadiustedtoimpressathinpieceoi lather, then the pressure will'be so grat as to cutratherthanmerely indentgreater.
