H. E. EDWARDS MARKING DEVI-GE Filed April 14 March 17, 1931.

vE EEE .tlpplicatien filed April it,

The present invention relates to marking devices and more particularly to marking devices for marking a line for use as guide in a subsequent operation such, for instance, as the application of overlays to shoe upper blanks. a

in the marking device illustrated and described in my Patent No. 1,758,884, April 5, 1930, the bed thereof carries a stationary pat tern for supporting an upper blank and a stationary ink pad for supplying ink to a marking pattern which is moved from a position where it engages the ink pad to a position where it engages the supported blank. The mark made by the marking pattern on the supported blank should be sharply defined to provide the operative, who performs the subsequent operation, with a legible guide line. At the same time the sharply defined line should be delicate to insure its registry with the overlapped overlay or other assembled part.

To produce this delicate guide line the marking pattern is provided with a depending flange terminating on its bottom in a narrow face, forming a marking edge. This edge, While sharp, is not sharp enough to cut into and injure the upper blank which is engaged but. once thereby. The sharp edge, however, engages the ink pad repeatedly and soon Wears an indentation into the felted or fibrous material of which the ink pad is composed. This indentation forms a trough in which the ink collects when the pad is replenished with liquid ink with the result that not only the narrow face forming the marking edge, but the adjacent sides of the depending flange pick up ink each time the marking pattern'is returned to the ink pad. The excess ink on the sides of the flange spatters or spreads onto the upper blank and remains there throughout the upper fitting and shoe making operations. The disfiguring spots or streaks of ink are not removed until the shoes arefinished, and therefore,considerable care and labor must be expended in eradicating' the ink. Sometimes, particularly in the case of shoes having ornate fabric uppers, attempts to eradicate the ink therefrom result in botcheries. Even if the excess ink ltldll.

does not actually spatter upon or spread onto the upper blank during the marking opera tion, it dries on the sides of the flange gradin ally thickening it, thus widening the mark-- ing face on the bottom thercot' with the result that on the upper blank a wide ra ged line is marked which causes irregularities in the subsequent operation. fits the overlapped part, an applique or an assembled upper blank, cannot hide con'iplctely the wide ragged guide line, the ex posed portions there of mustbe removed lJOlOl'B the shoes can be sold.

As the marking patterns used with my marking device are interchangeable, and as no two patterns are alike, the result is that in the continued use of the telted or fibrous ink pad it becomes sulcated by the cuttting action of the various sharp edges on the marking patterns. This condition promotes the transfer tor excess ink to the upper blank either directly, or through the thickening of the marking edge face throughout its length, or along portions thereof embraced by the ink containing grooves of the sulcated ink pad.

The principal object of the present invention is to provide a marking device of the class described with a marking substance pad immune from sulcation. I

To the accomplishment of this object a feature of the present invention contemplates the provision in a marking device of the class described, of a sponge rubber marking sub stance pad having a consolidated tegument.

While a sponge rubber pad having a consolidated tegument is capable of being engaged repeatedly by the sharp edge faces of the marking patterns without being sulcated, the consolidated tegument is impervious to the marking substance and therefore the capacity of such a pad as a source of marking substance is limited.

Accordingly, another feature of the present invention contemplates the provision in a marking device of the class described hav ing a pad and a marking pattern, of means for supplying the pad with marking sub stance during each cycle of operations of the marking pattern.

Ill

Broadly considered the means for supplying the pad with marking substance may take any convenient form found desirable or expedient. It is preferred, however, to employ a vulcanized sponge rubber roll having its tegument removed to render it pervious to the marking substance. The roll is transferred from a source of marking substance supply over the pad and back to the source of supply during each cycle of operations of the marking pattern. Preferably, the roll is transferred under pressure to insure its leaving a thin coating of substance material upon the consolidated'tegument of the pad.

Other features of the present invention consist in certain devices, combinations and arrangements-of parts hereinafter described and then pointed out 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 ining device spection of the accompanying drawings illustrating the best form of the invention at presentknown to the inventor, in which,

Figure 1 is a view inplan of the mark- Fig. 2 is a view in sectional elevation on the line 2-2, Fig. 1; i

Fig. 3 is a detail view in plan of one of the marking patterns, and 4 Fig. 4 is a detail view in sectional elevation on the line 44, Fig. 3.

In the illustrated embodiment of the invention the work to be marked, herein shown as a vamp 3 (Fig. 1), is mounted flatwise upon a gage4 with the peripheral edge of the throat 5 of the vamp engaged with a Wall comprising a plurality of small cylindrical blocks 6. Each of the blocks 6 is secured to one end of the shank of a rivet 7 (Fig. 2)-

which passes through the gate 4, the rivet being headed on the bottom'thereof. The

gage 4 is supported by a rectangular plate I 8 (Fig. 2) secured to the horizontal flanges 9 of abed 10 adapted to be supported from a work bench or table (not shown). The gage 4 is interchangeable with other gages and therefore is removably connected to the plate 8 by means of vertical dowels 11, se-

cured to the plate, which receives eyelets 12 vided both with a fingerhold 16 and a wrenchv engaging nut 17.

In the illustrated embodiment of the invention the vamp 3 is marked with a pair of lines 300 for use as a guide in a subsequent operation. Each line 300 is formed by a narrow face 18 (Fig. 3) formed on the bottom of a vertical flange 19 supported from a block 20. The block 20 is interchangeable with other blocks carrying marking faces 18 having different configurations and is therefore detachably connected to a crosshead 21 and to an operating handle. 22, substantially in the manner illustrated and described in the patent to l/Voodworth numbered 1,639,360, dated August 16, 1927. j

' At its front end the cross-head 21 is journaled on bearings-carried, respectively, by the upper ends of arms 23 and 24 projecting from the opposite ends of a horizontal rockshaft 25 journaled in the bed 10. At its rear end the cross-head 21 is journaled on bearings carried, respectively, by theupper ends of arms 26 and 27 projecting from the opposite ends of a horizontal rock-shaft 28 journaled also in the bed 10. Intermediate their ends the arms 26 and 27 carry, respec- 35 is rectangular and is loosely received in a trayv 36 formed on a horizontal portion of the bed 10 at a level above the pattern 4. engaging the handle 22 the operative may.

swing the narrow marking edge face 18 from p a position where it engages the ink pad-35 to a position where it marks the vamp 3, as shown by comparison of the full and con struction lines in Fig. 2. After the'marking operation the springs 33 and 34 return the narrow edge face 18 t0 the ink .padaided, it may be, by the operative through manipulation of the handle 22.

In order to prevent the narrow edge face 18 from cutting into the surface of the ink pad 35and thus forming a groove therein into WlllCh lnkmay collect for transfer to the sides of the flange 19, the ink pad 35 is provided with a smooth surface formed by the thick skin or tegument on a sheet of sponge rubber is vulcanized in a moldunder. heat and pressure so that the rubber surfaces adjacent the faces of the mold are consolidated to form a thick tegument extends ing aboutthe interior cells of the sponge rubber. The consolidated tegument presents a smooth elastic surface to the sharp marking edge 18 andresists the sinking of the sharp marking edge 18 deeply into the ink pad. The tegument is elastic so that the smooth surface thereof is restored intact immediately upon. the removal ofthe sharp marking edge 18. therefrom. The elasticity of the tegument prevents ink from being deposited upon any other portion of the flange 19 than the narrovv marking edge face 1d thereof. p

The tegulnent is, however, impervious to the ink supplied thereto and consequently the ink pad is limited as a source of supply to the amount of ink With Which the surface of the tegiunent may be coated.

in order that the tegument of the ink pad 35 may be supplied ,With a coat of ink each time the marking edge 18 is transferred from the ink pad 35 to the vamp 3, the rear edge of the tray 36 is embraced by a flange 37 on a shallow pan 38 forming a source of ink supply. The pan 38 holds a rectangular sheet or pad of sponge rubber 30, the tegument of which has been removed to render it pervious to ink. The pan 3% is secured by screws 40 to a block all provided with a flange 42 which embraces the bottom of the vertical rear face 32 of the bed 10.

In order to transfer ink from the source of ink supply to the tegument of the ink pad 35 the sponge rubber sheet 39 is engaged by a sponge rubber roll d3,'the tegument of which has been removed to render it pervious to ink. The roll 43 is supported by a shaft 44: provided with reduced portions lfi and 46 formed, respectively, near the opposite ends thereof. The reduced portion 45, is embraced ,by the hooked end of an arm ll which is loosely mounted upon a cotter-pin 48 carried by the arms of a'yoke 49 on the cross-head 21. The reduced portion 4:6 of the shaft 44 is embraced by the hookedend of an arm 50 Which is loosely mounted on a cotter-pin 51 carried by the arms of a yoke 52 on the cross-head 21. The roll-4&3 is pressed .into engagement With the sponge rubber sheet 39 by springs 53 and 5d. The spring 53 is coiled about the cotter-pin l8. The opposite ends of the spring53 are hooked, respectively, over the arm 4:? and one of the arms of the yoke 49. Thespring ti l is coiled about the cotter-pin 51 vvith its opposite ends hooked, respectively. over the arm 50 and one of the arms of the yoke-52.

."With this construction the roll T3 is pressed yieldingly into engagement with the sponge rubbersheet 39. When the handle is grasped by the operative and the marking face 18 is swung from a position where it en gages the ink pad 35 to a position. Where engages the vamp 3 the roll i3 is rolled over the sheet 39, the flange ill and the ink par 35. During its engagement With the sheet the roll 4-8 absorbs ink therefrom Which, as the roll d3 rolls over the ink pad 35, deposited thereon in the form of a thin film or coat. ll hen the marking face in is turned to the-ink pad 35 the roll 43 is returned into engagement With the sheet its shown in Fig. 2 the marking pattern swings through an arc in moving from its high level position in engagement with. the

it with the proposed design.

ever they are ink pad to its low level position in engage ment With theflvamp 3. During this and the return movement of the marking attern the axis of the roll 4-.1 travels in a horizontal plane DOt'Wl'tllStfllldll] the fact that the actuating member for the roll l -lis the swinging cross head 21. This straight line movement of the roll 43 is permitted by the springs 53 and 54: vvhich hold the roll 43 in engagement with the sheet 3801* the ink pad 35 independent of the position the cross-head 21 assumes during its swinging movement.

The roll. 4-?) may be removed readily from the device by freeing the shaft i l from the hooked ends of the arms ti and 50. The sheet 39 may be removed from the pan 3% Uvving to the porous nature of the sheet 39 it contains most of the ink in the pan. By removing the roll 4-3, the sheet 3.), by Wiping the shallow pan 38 and. the tegumcnt of the ink par 35, and by substituting another roll 43 and another sheet 39 for the ren'ioved roll and sheet, the device may be quickly changed to mark upper blanks with an ink of a different color.

its explained in my patent hereinhefore referred to, the marking pattern and the Work supporting and guiding gage d are corelated to mark a line, for use as a guide in a subsequent operation, on a predetermined portion of the Work. To this end the center lines of the pattern, gage and the "Work are arranged in the same vertical plane. The portion of the Work upon which the guide line is to be marked is predetermined by the shoe designer Who cuts out a pattern showing the shape of the upper blank. Cut through this pattern is a slot or an opening, the Walls of which represent the configura ,tion and location of the guide line desired.

This guide line is reproduced on the marking face 153 of the flangeltl. A blank gage' lis placed in position over the dowels 11 on the plate ll and the marking face ill bearing the proposed design is inked by engagement with the ink pad 35 and then swung into engagement with the blank gage t mark The pattern from the shoe designer is then placed on the gage l and the slot or opening in the pattern brought into registry with the proposed design marked on the ldy means of a pencil line is drawn on the gage t using one ed e of the pattern as a id'e. Then the isol to. blocks ti oi? the guide wall are inserted through the o that the line dravvn thereon is tangential to each of said blocks. ll lith this construction and mode of operation the marking pattern and the vvork supporting are corelated so that When-- assembled together in the marking device ir and the center line on the "WW i. gage at n it he in the v lflifl -lVl1ile the marking device of the present invention is designed primarily to mark a line to indicate the lap of oneupper blank over an adjacent, blank or the location of an overlay on the blank, it will be apparent that the marking pattern may be shaped to mark a line to indicate the location of stitches having utilitarian or ornamental functions.
