h Fig. 6 a plan view of a lank formed in the ,9 machine and provided with an embossed a I 's invention relates to improvements in rubber cut and em m calendaring machines articularl adapt *for forming articles sheet-rubber, such as overshoes, where it is desirable to provide the edges with a raised surface or rib and to cut out the blank for the overshoe, so that, whencut out,

it 1 be provided with an u:-:-- edge. We. are aware that previous to our 1nventio it had been pro sed to construct m es to calender em s and cut sheetrubberstock. Suc machines, however, would be of very limited utility, since they would be capable of handling but one thickness of stoc owing to the fact that both the embossing and cutting functions would devolve upon a single roll.

.The object of our invention is to rovide a machine of the character descri ca able of calendaring, embossing and cutting eetrubber stock of'difl'erent thicknesses without necessita the substitution of rolls for each desi th'ckness of stock. 45 -With this object in view, our invention consists in a calendaring, embossing and cutt' I machine characterized by having an roll and a calendering roll which are relatively adjustable, and a separate and distinct cutting roll co-agiizgg with the em-' bossing roll and synchro therewith. In cfl l'lyifi out 'our invention, we employ a air 0 ender-rolls and 6, arranged si e by side and mounted in asuitable frame 7, thebearin 8 for the ends of the roll 5 being adjusta le by means ofca stan screws 9 mounted in tes 10 pivota connected at one end wit the frame of t e machine and ada ted to be secured at the opposite end to the me of the machine by screws 11. Directly below the calender-roll 6 is a third calender-roll 12, thebearings 13 of which are adapted to be, raised and lowered b screws 14 provided at their lower ends wit worm ggars 15 meshing with worms 15'. adapted to turned through a bevel-gear 16 meshing with a bevelimon 17 on the lower end of an operating-r0 18.. which pro'ects u wardly and rearwardly, and is rovi ed wit an operating hand-wheel 19. t will be understood that both ends of theroll 12 are provided with adjusting means (Fi 1 and 3). At

the side of the calender-r01 12 is an' emboss- -roll 20, formed in its surface withchanno 21 corresponding in form to the design of the embossing to appear on the surface of the finished article. This roll is also mounted in the frame find provided at opposite ends with bearing-blocks 22 adapted to be adjusted bycapstan screws 23 mounted ingates 24 hinged at their upper ends in the frame and connected at their lower ends with the frame bybolts 25. Directl below the embossing-roll is a cutting-r01 26 supported on bearing-blocks 27 which are are loose on a shaft 35 and on this shaft, ad-

Lacent to each worm, is a sliding clutch-memr 36 keyed to the shaft 35 and adapted to be moved into or out of en agement with the worm by operating-hand e337, so that the cuttin -roll may be adjusted at either or, both ends y a hand-wheel 34;

' It will be understood that the calenderrolls, embossing-roll and cutting-roll are provided at the ends with the usual gear.- wheels by which they are moved at the desired relative speed and driven by any suitable means, not shown.

Forwardof the calender-roll 6 is .a'slotconveyor 38, driven from one of the shafts by .thelowersha '41 which is "Stock a 39 en with a sprocket the u per aha 41 of the conveyor,

K 42 being connected with the upper shaft 41 by links 43tfixed-to the shift a -wb 44, so that the lower end of the conveyor may be turned upward when desired.

is fed between the calender-rolls 5 and 6, by which it is sheeted, and passes downward between them andbetween the calender-rolls s and 12, where" the stock is further reduced in thiclme'ss. The stock then follows theroll 12 and theembossingroll 20, where the stock is forced into thegrooves 21 therein, and, at the same time, may be further reduced in thickness by compression between these two rolls. The stock then passes between the embossin -roll 20 and cutting-roll 26, which is provi ed with cutting-edges 45 corresponding to the design to be cut out, and the design is so arranged that they are connected with the next form, so that the forms are delivered from the machine in a continuous strip. The surplus material is carried upward by the embossing-roll and onto theconveyor 38, by which W1 may be adjusted with relation to theemit 18 carried up and delivered between the rolls 5 and 6 for further manipulationand through the machine.

this construction, the cutting-roll bossmg-roll, so that the distances between them always correspond to the projection 'of the cutters beyond the cutting-roll, so

that, as these wear down, the cutting-roll may be raised so as to always be operative .stochasit until the cutters are worn down below a redetermined point, according to the thickness of the stock passing through.

The article cut out, herein represented in Fig. 6, is a blank for an overshoe, and is provided around its upper edge with an embossededge 46 of any desired configuration this embossin being formed in the rough the'machine, so as to avoid v e necessity of a separate operatlon.

arranged side by side, a third calender-roll arranged directly below the second calendersaid worms with and means for coll, an embossing-roll arranged forward of and in line with the third calender-roll, a cutting-roll arranged below the embossingroll, means for dnvi said rolls, said cutting-rolls mounted on arings on verticallyarranged screws, worm-gears on the lower ends of said screws, worms meshing with said wormrs, said worms arranged on a horizonta shaft, means for coupling said worms with said shaft, and means for turnlng said worms, including an upwardly and forwardly projecting operating-shaft.

3. In rubber cutting and embossing calenderin calen e tion, other calender-rolls cooperatin therewith and arranged in relatively ifl'erent planes with respect thereto, said last mentioned calender-rolls being mounted for relative individual adjustment with' respect to the fixed calender roll and the direction of such adjustment being at different angles, an adjustable embossing-roll arranged adjacent to and in the same plane as one of the adjustable calender-rolls and having a direction of adjustment parallel to the remaining calender-roll, and an adjustable cutting-roll adjacent said embossing-roll machines, the combination with a r-roll having a fixed axis of rotav and having a direction of adjustment parallel with that of the calender-roll mounted adjacent to the embossing-roll whereby various gauges of stock maybe cut and embossed by relatively'adjusting the cuttingroll andem rol1. 4. In a machine of the class described, the combination with a calendering-roll, of an embossing-roll co-acting-therewith, means for adjusting one of the said rolls with reect tothe other roll, a separate and distinct cutting-roll co-acting with the said embossing roll and synchronized therewith and means for driving each of the said rolls:

5. In a machine of the class described,

the combination with a plurality of calendering-rolls arrangedin series, of an embossing-roll co-acting with one of the: said calendering-rolls, means for adjusting the space between the said embossing roll and its soacting calendering roll, a separate and distinct cutting-roll co-acting with the said embossing-roll and synchronized therewith, and' means for driving each of the said rolls.

v In testimony whereof, we have signedihis specification.
