12 Claims.

This invention relates to machines for marking shoe upper sections or similar pieces of sheet material, and particularly for performing the method of marking described in the Edwards Patent No. 1,639,332, dated August 16, 1927.

In the manufacture of shoes, particularly womens shoes, it is customary to apply ornamental designs to the shoe uppers, as by stitching, perforating or embossing. Present fashions demand that shoe uppers be made of leather, textile fabrics such as silk, satin or velvet, and various other kinds of sheet material. Usually, the ornamental designs are applied to the cut-out sections of the uppers before they are assembled in the shoe; and in the case of stitching, the designs are first marked on the shoe uppers and the marked designs are then followed in the stitching. As explained in said Edwards patent the design may be impressed upon the shoe upper section, or similar article of sheet material, by a marking plate, on which the desired pattern is formed by bosses punched from the material of the plate and disposed inlines, rows or other arrangements to delineate the pattern. The marking plate is then impressed upon the shoe upper section or other piece 'of work to be marked, with a transfer sheet, against the opposite side of work, and the pattern displayed by the bosses will then be printedor impressed on the work. A

' similar method may be used without the transfer sheet for merely embossing a piece of leather, in which case the marking plate will be embossed in accordance with the desired design, or for perforating the work, in which case the marking plate will be made with bosses in the form of cutting punches of such shape and arrangement as to cut holes or perforations in the work, shaped and arranged according to the desired design.

Printing or marking, perforating and emboss ing, whether used separately or 'in various combinations at the same time, are all included in the expression marking as herein used; and the term marking plate is used. to designate theplate for applying the design to the work whether the plate is constructed for printing from a transfer sheet, or for perforating, or for embossing, or for any combination of these operations.

One object of the invention is to provide a marking machine having a normally inactive reoperated to impress the desired design on the work when a, platen, supporting the work and the marking plate, is moved into operative relation to the press member, and to stop the press memciprocable press member which'is automatically ber when'the platen is moved'away from the press member.

Another object of the invention is to provide means by which the marking'plate is automatically controlled so as to rise or move away from the platen to permit the placing of the article to be marked upon the platen or permit it to be removed from the platen, when the platen is shifted out from under the pressmember, and to move the marking plate into operative position overlying the work on the platen when the platen is shifted to operative position under the press member.

Other features of the invention are mechanism for automatically advancingthe transfer sheet each time the platen is moved in and out of operating position with relation to the press member; means for detachably and interchangeably mounting the marking plate on the platen: and for correctly positioning the same thereon; workpositioning means associated with the platen; and the mechanisms for controlling and actuating the various parts. I

These and other features will be herein more fully described and particularly pointed out in the claims.

. Referringfirst to the form of machine shown in Figs. 1 to 11, the frame ofthe machine consists of'a base 10, adapted to rest upon and be secured to a bench or similar support, and an upper frame 11 in the general form of an arch.

The base 10 is provided at opposite 'sidesrwith guideways or grooves 12 withinwhich the work- 'supporting platen, indicated generally at 13', is

mounted to slide forward'and backward intoandout of operative position with relation to a reciprocable plunger or press memberk52, carried by the frame 11. The platen 13 is provided at its front end with a handle 14 by which it may be manually moved back and forth along theways 12. In thedrawings the platen 13 is shown occupying-its outermost position away from'the press member, in which position the machine is at rest. a 1 a v The body or bed 15 ofthe platen is preferably a rectangular casting. Near each corner it is formed with a vertical hole 16 (Fig. 6) whose upper por tion is of smaller diameter than its lower portion.

The lower end of the hole 16 is closed by a plug 17 which serves as an abutmentfora coil spring 18 by which a plunger 19 is yieldingly supported. with its upper reduced end 20 projecting above the top surface of the body 15 of theplaten.

J Resting on top of the platen 15 is aremovable work-positioning: plate 21 preferably, made of cardboard or similarsheet material and provided near each corner with a small aperture reinforced by an eyelet22, each eyelet-being adapted tobe fitted uponthe upwardly projecting reduced end 20 of one of the plungers 19. Thus theplungers 19 serve=-to hold the. work-positioning plate 21 in a definite position on top of the-platen. 15 so that it-will not be displaced laterally but can; readily beremoved when desired. The wcrk-positioning plate 21 is made with a cut-out or recess 23 (Fig. 8) so shaped asto receive and-properly to position the piece ofwork to be marked, such as the vamp or forepart of a shoeupper24, or other piece of sheet material. As herein illustrated the cut-out 23 of the work-positioning plate 21 is formedwith opposite side edges 25, 25 to engage the opposite side edges of thefsheet article 24 to position the saine laterally, and with end edges to engage the outer end of the article 24 thereby to'position the same longitudinally. .It is not necessary'that the out-out 23 should exactly conform'in all respects to the. shape of the article 'to' be'marked but it must be of such shape and dimensions that it will receive the'article to be marked and will'fit it sufliciently closely at. a sufficientnumber of points to position it definitely andaccurately to -be properly operated upon by the markingpl te. Itwill be understood that for each different shape andsize of article to be marked a difier'ent work-positioning plate 21 will be used havinga cut-out adapted to thesize and shape'of the workin question.

Near the innerend-of the platen115 (Figs. 2, 5,. 8 and 11) is a marking plate holder indicated generally at "26, comprising a transversely disposed rock-shaft 27 which rests at" its opposite ends within sockets28 provided in a brack'et'lh secured to the end ofthe platen body. The hear: ing ends of the rock-shaft 27 are held within the sockets 28 by means of detent plates 29 secured in position against the opposite sides of bracket l5 by screws 30. The screws 30 occupy slots formed in the detent plates 29 so that by loosening the screws and retracting said plates the holder 26 can be removed from the platen.

Secured to the upper flattened side of the rock-shaft 27 by means of rivets 31 is'a rigid bar 32 (Figs. '7 and 8) and secured to the top side of this bar .32 by the same rivets is a strip of resilient sheet metal 33, which is of greater width than the bar 32 so that its margin extends inwardly beyond the bar as best shown in Fig. 7. The free or projecting margin of the strip 33' is transversely slitted at intervals, as best shown in Fig. 8, to provide a row of spring tongues 34 each of which is embossed to provide a rounded. boss orprojection 36 upon its under side (Figs. 7 and 8).

The marking plate, which is detachably secured to said rock-shaft, is shown at 37 and is preferably made of a piece of sheet metal such as galvanized iron embossed or otherwise formed to provide marking projections or bosses 38 .on its under side (Figs. and 9). The marking plate 37 is of such shape and size as to enter the recess or cut-out 23 of the work-positioning plate 21, and is of a shape conforming at least approximately to the shape of the work. At its inner end the margin of the marking plate 3 7'is bent .at right angles in opposite directions on two parallel transverse lines to provide a step 39 and a lip 40 (Figs. 7 and 10), the lip 4l) being parallel but offset relatively to the body of the marking plate. ,The bar 32 forming part of the holder for the marking plate is-cut away or stepped upon its inner under side to provide a groove 41 between the bar and rock-shaft 27 into which the lip 40 of the marking plate is inserted. Along the margin of the marking plate 37 near the step 39 there is provided a series .of holes or sockets 42, each of which is adapted to receive and engage one of the projections 36 on the tongues 34 (Figs. 7 and 10) when the marking plate is attached to the holder. In assembling the marking plate. on the holder the lip- 40 is inserted in the groove 41 and the plate then pushed home,

'detachably to secure the. marking plate to the holder so that it can readily be removed and re placed by another marking plate of difierent pattern. It will also beapparent that if desired two or more marking plates can be attached to the holder side by side at the same time, which is sometimes desirable in impressing a plurality of patterns on different parts of the article to be operated upon; V

Alongside of the rock-shaft 2'7 and parallel thereto is a take-up spindle 43, on which "is wound one end of a transfer sheet 44 extending from a supply spindle 45, on which is wound a supply roll 45% of the transfer sheet. The transfer sheet extends across the body 15 of the platen and then underneath the rock-shaft 27-to' the take-up spindle 43. The supply spindle 45 is journaled at its opposite end in bearings provided upon a bracket 46 securedto the outer end of the body 15. 'The' handle 14 is fastened to the bracket 46. A handwheel 4'? is provided at one end of the supply spindle 45 and a handwheel 43 is provided at one end of the take-up spindle 43, by which said spindles, respectively, may be manually rotated if desired.

The take-up spindle 4.3 is supported at its ends within open sockets 50 (Figs-5, 8 and 11) formed in the top of the sides of bracket l5. Normally the spindle 43 is held within the sockets by the detent slides'29. Each detent slide 29 is made with two hooks, 51 and 51 the former serving to lock the rock-shaft 27 within its bearing socket 28 and the latter serving to lock the spindle 43 within its bearing socket 50. When the detent slides 29 are retracted, which can be accomplished by loosening the screws 30, both the shaft 27 and the spindle i3 may be removed from the machine.

To prevent accidental rotative displacement of the spindles 45 and 43, leaf springs 48 and 49 fastened to the under side of the body 15 of the platen bear against the under sides of the rolled up transfer sheet wound upon spindles 45 and 43, respectively.

The transfer sheet 44 is similar to carbon paper but its coating is preferably softer than the coating of carbon paper so that the transfer will be made more readily. It is placed on the platen with its transfer surface upward. The coating I of the transfer paper is preferably of a suitable colorto be readily distinguished from the color of the article to be marked.

Fast on the take-up spindle 43 near one end thereof is a ratchet wheel (Figs. 8 and 11) cooperating with a pawl 96 pivoted at 9'7 on the machine frame and normally resting by gravity against a stop stud 98 projecting from the frame. The end of the pawl 96 is in the path of the lower side of ratchet wheel 95 so that when the manually moved platen reaches the limit of its outward movement away from the press member, the ratchet wheel 95 engages the pawl and is rotated to the extent of one tooth, thereby advancing the transfer sheet the same distance. When the platen is thereafter shoved inwardly the pawl 96 is idly rocked by the ratchet wheel and as soon as the ratchet wheel passes out of engagement with the pawl the latter is returned by gravity to its normal position against stop 98. Thus, each time the platen is operated in and out its motion is utilized to rotate take-up spindle 43 the distance of one ratchet tooth thereby winding up the transfer sheet 44 on spindle 43 and presenting a fresh unused portion of the transfer sheet to the action of the marking plate for each operation thereof. A stop 53 (Fig. 2) at the side of the platen limits the outward movement of the platen, as hereinafter more fully described, and the pawl 96 is so positioned relatively to the stop that when the platen is arrested by the stop 53 the ratchet wheel 95 and the pawl 96 are in substantially the position shown in Fig. 11.

An important feature of the present invention is that when the platen 13 is shifted to its outermost position away from the press member, the marking plate 37 is automatically raised and held in open position to permit free access to the top of the platen so that the operator may place the shoe upper sectionor other article which is to be marked in position within the recess 23 of the work-positioning plate 21; and that when the platen is'shoved inwardly under the press member the marking plate 37 will be lowered to operative position over the work upon the platen so as to impress the markings upon the work when the press member is operated. Upon again The mechanism i at an incline to cooperate with a cam 55.(Figs'.

1, 2 and 3) which is formed by an upwardly bent inclined end of a lever 56 fulcrumed at 57 on top of thebase 10 of the machine frame. 'This lever is yieidingly held in normal position with the cam 55 in the path of arm 54 by means of a leaf spring 53 secured to the-side of the base 10. The lever 56 is provided with a'laterally and downwardly extending bracket 59 which engages the outer side of the base 10 and serves as a stop to limit the inward swinging movement of the lever 56 under the influence of spring 58.

The free end of bracket 59 is formed with a slot 60 (Fig. 2), against the inner end of which abuts a pin 61 projecting upwards from the stop bolt or latch 53. The stop latch 53 extends through and slides in a hole in the base 10, into the guideway 12 for the platen and into the path of stop shoulder 8'? of the platen, and is normally urged by a spring toward its operative position. The stop latch 53 is free to move endwise independently of the lever 56 but when the latter is manually swung outward on its pivot57 by means ofa handle 88 it acts through bracket 59 and pin 61 to retract the stop latch 53;

l The cam or abutment 55 is normally positioned so that-when the platen is moved outwardly and is nearing the end of its movement in that direction the arm 54 on rock-shaft 27. engages the cam 5-5 thereby rotating the rock-shaft [and swinging the marking plate 37 into its raised or open position. The shoulder 8'7 on the platen engages the stop latch 53 to stop the platenan'd hold the marking plate 37 in raised position while the platen is in its outward or inoperative position with relation to the press member. When the platen is shoved inwardly toward the press member the arm 5s moves away-from the cam 55 thereby permitting the spring 62, aided by gravity; to rockthe shaft 27 in the opposite direction and swing the marking plate 37 down into operative position upon the work 24 which is held within the cut-out of the work-positioning plate 21.

Inasmuch as the marking plate 37 is a thin sheet of metal and is sometimes thrown upwardly rapidly and with? considerable force by the engagement of arm 54 with cam 55, it is desirable to provide means to arrest the marking plate when raised to its elevated positionand to prevent-undesirable vibrations thereof. To this end a wire bail-100 (Figs. 1 and 3) is provided, the two side arms of which. supported by the frame 11, with the transverse-stretch of the bail in a position to act as an abutment or stop against which the marking plate 37 strikes when raised to itsfully open position. i

The spring 62 which urges themarking plate towards its lowered or closed position is attached at one end to one of the screws 39, by which the detent slide 29 is held in position, while the other end of the spring extends partly around the under side of rock-shaft 27 and is fastened thereto at 63. The spring 62, therefore, which is normally wiseand outwardly thereby removing the cam55 from the path of arm 54 and at the same time I retracting thestop bolt orlatch 53. The platen ment pin 68 which-bears against arm 65.

is then'free to be drawn forwardly out of the machine.

It is also an important feature of the present invention that the movement of theplaten inwardly to operative position under the press member 52 controls mechanism by which the press member is automatically operated to press the marking. plate upon the work. This is accomplished by the following mechanism.

.In the path of the inner end of the platen body is a stem 64 (Figs. 2 and 3) adjustably fastened to an arm 65 by means of a clamping screw 66. The arm 65 is mounted upon a slide bar 67 supported in a slideway in the base 10 and is provided at its rear end with an abut- The .opposite end of slide bar 67 is made with a laterally'extending lug or abutment 69 to engage with the depending shipper arm 70 of a clutchcontrolling lever 71 fulcrumed at 72 (Figs. 1 and 3) on the frame 11 of the machine. The lever 71 actuates an upwardly extending arm 73 carrying at its upper end a wedge-shape cam 74 struction.

cooperating with an adjustable member 75 forming part of, a clutch mechanism 76 of usual con- When the member 75 is moved toward the left (Fig. 1) by wedge 74 the clutch is disengaged and when the wedge 74 is disengaged from member 75 the latter is shifted by a spring (not shown) toward the right to set or engage the clutch. The clutch 76 is mounted on a transversely disposed shaft .77 journaled in bearings at the top of the frame 11 and on this shaft 77 is loosely mounted a continuously driven pulley 78 to which one of the clutch members is fixed. When theclutch 76 is set the pulley 78 acts to rotate shaft 7 and when the clutch is thrown out the shaft 77 is at rest. A spring 79 (Fig. 3) acting against the shipper lever yieldingly urges the upper arm 73 toward theclutch-shifting member and also acts through lever 70 to hold the slide bar 67 at the limit of its movement toward the right (Fig. 2). Thus the wedge 74 is normally held in position'to engage the clutchshifting member 75 so that the clutch is normally disengaged and the press member 52, actuated from shaft 77, is normally inactive.

Fast on shaft 77 is an eccentric 80 connected bya pitman 81 with the upper end of the press member 52. It will be understood that the press member is mounted to slide on vertical ways provided on the frame 11 and is reciprocated vertically by shaft 77 and the eccentric connection when the. clutch is in engagement.

When the platen 13 is shoved inwardly to the limit of its movement'toward its operative posi-.- tion under the press member the rear end of the platen body 15 will engage the end of stem 64, thereby moving the stem 64, arm 65, slide bar 67 and lever'70 toward the left, as viewed in the drawings, whereupon the clutch 76'will be engaged and the press member will be reciprocated vertically by the eccentric 80 until the platen is again pulled forwardly out of operative relation to the press member. The inward movement of the platen is limited by the engagement of the arm 70 with the frame of the machine and the outward movement of the lever 70 in the opposite direction under the influenceof spring 79 is limited by the engagement of the arm 65 on slide 67 with the rear side of the frame 10. V a

The body 15 of the platen is provided upon its underside with anti-friction rollers 82. loosely mounted within rectangular pockets 83 provided on the under side of the body 15 (Figs. 4 and 5). These anti-friction rollers are held against falling out of-the pockets 83 when the platen is removed from the machine by strips of metal 84 fastened by screws to the bottom of the body 15.

The rollers are also held against endwise movement in the pockets 83 by small plates 85 fastened toopposite sides of the body 15. The base 10 of the frame is made with a plurality of parallel runways 85 (Figs. 1 and 2) on which the antifriction rollers 82 travel as the platen is moved back and forth. I

The marking plate 37 is provided on its top side with a pad .37 (Figs. 3, 8 and 10) which may consist of a piece of cardboard of a size and shape corresponding approximately to the size and shape of the marking plate 37. This pad receives the direct impact of the press member 52 during the marking operation. A rubber pad or similar cushion 52 may be provided on the under side of the press member 52, if desired. In practice the pad 37" may conveniently and economically be made from the piece of cardboard cut out from the work-positioning plate 21 to form the recess 23. This piece, which would otherwise be waste, may be utilized as the pad by trimming it slightly to fit the marking plate and fastening it, by cement for example, to the top.

side of the marking plate. a

The operation of the machine, which will be evident from the foregoing description, may be briefly summarized as follows: When theplaten is pulled forwardout of its operative relation to the press member 52 the press member will be at rest or inactive and the marking plate 37 will be held in raised or open position by the engagement of the arm 54 with the cam 55. The operator then places the shoe upper section or other article of sheet material to be operated upon in correct. position within the recess or cut-out 23 of the work-positioning plate 21 with the surface which is to be marked downward in contact with the marking surface of the transfer sheet 44. The

platen is then shoved inwardly into operative position under the press member 52. During the first part of the inward movement the marking plate 37 swings down to closed position upon the platen overlying the work held Within the workpositioning plate 21. Just before the platen reaches its innermost or operative position under the press member, it actuates the shipper lever 70, thereby setting the clutch 76 and causing the H press member 52 to descend on top of the marking plate, whosepattern is thereby impressed on the under side of the work by the transfer sheet 44; or directly on the work if no transfer sheet is used. When the press member rises the platen V is again manually pulled out to inoperativeposition whereupon the clutch 76 is disengaged and the movement of the press member is stopped; and when the platen reaches its outermost position the marking plate is swung upwardly to-its': open position and the operator removes the marked article from the platen. The machine is now in condition to receive another piece of work and the operation is repeated.

Inthe modified construction illustrated in j the rock-shaft 27 and the other end is engaged,

by a releasable latch 93 pivoted to the rockshaft at 94. The marking plate 37 is provided at its inner end with a perpendicular flange 39 formed with notches 94,-spaced to correspond with the studs 89, so that when the marking plate is applied to the rock-shaft 27 the engagement of the notches 94 with studs 89 will properly position the marking plate and hold it against displacement. After the marking plate has been placed in position on shaft 2'7 the clamping bar 91 is swung downward into closed position against the flange 39 and the latch 93 is engaged with the free end of the clamping bar to hold the parts in place. This detachable connection, like the ones shown in Figs. '7 and o8,'permits two or more marking plates to be attached side by side to the rock-shaft at the same time if desired.
