To will whom t may concern: y

Be it known that I, GEORGE MOORE, a citi# Zen of the United States, residing at Boston,

in the county of-Suffoll, State of Massachul setts, have invented a certain new and useful Improvement in Machines for Embossing and Printing Upon Leather, Silk, and other Material, of which the following is a specification, reference being had therein to the accompanying drawings. I My invention consists in a machine of novel and improved character which I have designed for use more particularly in printing in gold, silver, &c., upon leather, silk, and other material. I

I have shown in the accompanying drawings a machine embodying my inventionin the best form in which it has thus far been reduced to practice by me.

In the drawings, Figure 1 shows the said machine in side elevation. Fig. 2 is an end elevation .of the said machine. Fig. 3, Sheet 3, is an isometric showing the platen and also a bar or plate with a sheet or strip of leather or other material applied thereto in readiness for being embossed or printed. Fig. 4, Sheet 3,. is a sectional' detail showing chiefly the mode of mounting the rack upon the platen. Fig. 5, Sheet 1, is an end elevation ofthe cylinder. Fig. 6,Sheet 3, is a representation of the cylinder in longitudinal section, showing certain of the burners thereof. I

Having reference to the drawings, the machine which is shown therein is provided with a supporting-framework -comprising opposite side frames 1 1, which in their lower 4portions are connected by means o f a spacing and tie piece 2 and upon the tops of which a bed or table 3 is mounted, from the opposite sides of which rise the standards4 4, the said standards having the upper ends thereof connected by the pair of spacin and tie rods 5v5. 6 is a horizontal p aten located above and parallel with the bed or table 3 and supported upon the latter by means of a series of rolls 7 7, Sc'c'., intervening between the underl surface ofthe platen andthe upper surface of the bed or plate and rolling upon the latter surface as reciprocating movements are communicated to the platen. The rolls 7 7, &c., are .arranged in groups upon the parallel cross-rods 71 71, &c., which latter have their opposite ends connected to side bars 8 8, the extremities of the said side bars being joined by other rods 9 9. -The side bars and cross-rods 71 71 9 9 form a rectangular frame y Specification of Letters Patent.

Patented March 20, 1906.

by means of which the rolls 7 7, &c., are maintained assembledlin working relations; l From the opposite ends of the bed or table 3 pairs of arms 10 10 extend inthe direction of the length of the said bed or table. ends of the said arms are upturned, and the upturned ends of each of the said pairs are connectedby means of a cross-rod 11, on which is mounted a roll 12 between collars 121 121 on the said cross-rod, the said collars preventing the roll from movement lengthwise of the cross-rod The rolls 12 12 support the platen 6 as it approaches the extremes of its reciprocatory movements. rllhe platen is grooved on its underside at the middle of the width thereof and the bed or table` 3 is grooved at its upper side, the grooves receiving projecting peripheral portions of the middle line of'rolls 7 7 and of the rolls 12 12. Thereby the platen is prevented from becoming misplaced transversely within the machine during operation.

The standards 4 4 are slotted vertically, and in the slots 41 of the respective standards are received the boxes 42 42, containingV the The bearings for the shaft 131 of the cylinder 13.

The boxes 42 42 are supported by spiral springs 43, which are contained in the slots 41 of the standards, the lower ends of the said springs resting uponthe flat upper sides of semicircular blocks 44, occupying thelower ends of the said slots. The springs 43 tend to raise the boxes 42 42 andthe cylinder 13. Other springs 45 are placed within vthe slots 41 abovethe boxes between plates 46, resting upon the latter and upper plates 47. The.l

said springs 45 are compressed between the said plates and tend to press the boxes and cylinder Y toward the platen with yielding force. The tension of springs 45 is regulated at will by means of pressure-screws 48 48, Working in threaded holes that are tapped in the upper ends of the standards 4 4 and taking bearing by their lower' ends against plates 47 47. I

For the purpose of-enablingfthe cylinder 8 to be turned upon its axis a hand-wheel132 is mounted kupon one end of the shaft 131 thereof, the said end vprojecting beyond the bearing 42 at such side of the machine to receive the said hand-wheel.

The impression-surface is provided upon the cylinder 13 in practice, while the sheet or strip to vbe printed or embossed is supported upontheplaten 6.

vAs thusl far described the machine is or i may be essentially as heretofore in platepresses, and the features, construction, and arrangement are not in themselves of the gist of the invention. l

In carrying my invention into effect in order that as the cylinder is turned upon its axis the platen may be moved lengthwise to present all portions of the length of the said sheet or strip properlyT to the different portions of the said impression-surface the cylinder and platen are geared together by means of a gear-wheel 133, with which one end of the cylinder is formed or provided, and a rack 61, with which the platen 6 is furnished. Thus when the cylinder` is partially rotated in one direction the platen is moved endwise in a corresponding direction to carry ythe sheet or strip resting thereupon past the cylinder to receive an impression, and thenafter the said sheet or strip has been removed from the platen and replaced by another rotation of the cylinder in the opposite direction will be accompanied by travel of the platen in the opposite direction, carrying the second sheet or strip past the cylinder .to receive an impression, and so on. To limit the closeness of approach of the surface of the cylinder 13 to the surface of the platen, the platen is-furnished at its opposite sides with ribs-62 62, extending lengthwise of the same, and with the upper surfaces of which the periphery of the body of the roll makes contact when not prevented from so doing by the intervention of the sheet or strip that is to be embossed or printed and its backing between the impression-surface upon the cylinder and the platen` I provide the cylinder 13 with an impression-surface which is constituted by a removable band or jacket 14. The said bander jacket encircles the periphery ofthe cylinder and fits closely thereagainst. It is engraved lor cut upon its exterior surface according to the design, &c., which it is desired. to emboss or imprint. Preferably the said bandA or jacket is split transversely or discontinuous and is provided with means to clamp itr securely to the periphery of the cylinder. In the illustrated embodiment of the invention the opposite ends of the vband or jacket are furnished with blocks or lugs 141 141, which are formed with open-ended radial slots 142, the said slots receiving the stem of a tightening and securing bolt 143. An enlargement or head with which oneend of the said bolt is furnished takes against the outer side of one lug, while a nut 144 upon the threaded stem of the bolt takes against the outer side of the other lug. By means of the bolt and nut the band or jacket may be tightened upon the exterior of the body of the cylinder,` and thus effectively secured in place, while by unscrewing the said bolt and nut the band f or jacket will be loosened. In order to enable the band or jacket conveniently to be applied to or removed from the cylinder, a space 135, corresponding in width with that of the band or jacket, is left at one end of the cylinder between such end and the adjacent standard 4. This enables the band or jacket in being applied to be passed by a movement in a transverse direction with relation to the axis of the cylinder into the said space. The opening between the ends of the bandv or jacket permits such ends to be passed at opposite sides of the corresponding journal of the cylinder, and after the band or jacket has been caused to assume concentricity with the periphery of the body of the cylinder the band or acket may be moved lengthwise of the said body into place upon the body, after which the bolt 143 will be applied and tighti ened. The removal of the band or jacket is effected by the reverse operations, as will be understood.

Provision is made for heating the cylinder as follows: In the opposite heads of the cylinder are set pipes 16 16, &c., extending in the direction of the length of the cylinder at suitable distances apart around the axis of the cylinder. To the outer extremities of the said pipes at the heads of the cylinder are fitted swiveling connections 161 161, &c with which are joined flexible gas-supply pipes 162 162. In the case of certain of the pipes 16 the swiveling connections 161 161 are combined therewith at one end or head of the cylinder, while in the case of the remainder, which alternate with those first referred to, the swiveling connections are combined therewith at the other end or head of the cylinder. Gas flowing through the supplypipes 162 162 passes by way of the swive ing connections 161 161 into the interior of the pipes 16 16. These last have iine holes 163 163 made through the shells thereof. Through the said holes the gas flows and is ignited, lie pipes 16 16, &c., constituting burners. addition the shaft of the cylinder is tubular and between the ends or heads of the cylinder is also furnished with a number of holes 136 136, one outer end of the said shaft having a coupling 137 swiveled thereto, the said coupling having in connection therewith a supply-pipe 138. The shaft of the cylinder constitutes an additional burner. templated that in practice gas will-be permitted to flow through the outlets or holes of the walls of the various burners until the cylinder has become su'lliciently heated, after which the flow through the outer burners 16 In i ITO

It is con- 16, &c., willbe discontinued, leaving in aclis to be operated upon and yproperly present-` ing the same to the action of the impressionsurface ofthe cylinder I provide a bar or plate 17. This bar or plate is rabbeted or reduced in thickness on the upper sidethereof at its` its end portions overlapping the` shoulders thereof, as in Fig. 3, in which the sheet or stri is designated 18, and then swinging the bai s down, so as to depress the en`d portions of the sheet or strip around the shoulders, which will cause the said end portions to be clamped between the shoulders and the cross portions of the bails. After the sheet or stripV 18 has been applied to the bar or plate 17 and its end portions have been clamped, as aforesaid, the said bar or plate is laid upon the platen 6, the latter being then in one of its eX- treme positions. For the purpose of gaging the position ofthe bar or plate when applied to the platen gage-pins 63 83 are provided upon the latter, and for engagement with the said gage-pins the ends-of thebaror plate are notched, as at 172. The bar or plate 17, with the sheet or strip 18 of leather, silk, or other 'material .applied thereto, having been laid upon the platen, the cylinder is rotated by means of the hand-wheel in the direction to advance the platen endwise with relation to the cylinder and cause'the impression-surface of the latter to act t'o emboss or print the said sheet or stri If the sheet or strip is to be printed in go d, gold-leaf is laid upon the upper surface of the same before the bar or plate,with the sheet or strip thereon, is placed in position upon the platen. y

In order to compensate for differences in the thicknesses of successive sheets or strips 18,' as well as variations in the thickness of different portions of a given sheet or, strip in the direction ofthe length of the latter, the vertically-movable boxes 42 42 of the cylinder 13 are acted upon by the depressing-- springs 45, which cause the surface of the t band or jacket 14 to bear with predetermined pressure against the upper surface of the sheet or strip. In order to enable the teeth of rack 61 to retain proper working relations with the teeth of the gear 133, which is connected withthe cylinder, the said rack is lsup- -ported upon springs 65 65 on the platen 6 andlis movably secured to the platen. In this instance the rack is provided with a flange eX- tending downward alongside the corresponding edge of the platen, the said flange having vertical slots 66 66 &c., made transversely therethrough, and the rack being held to the platen by means of screws 67 67, the stems of which pass through the said slots into threaded holes that are 'tapped into the edge lof the platen.V The Vsprings and slots enable vthe rack to move vertically, and thereby accompany the gear-133 asthe cylinder rises and sinks.

, The. gear connection between the cylinder and platen insures a proper register between the embossing or printing surface of the ring, band, or jacket 14 upon the cylinder and the surface of a strip or sheetV of material carried by a work-holder that rests uponY the platen subjected to a second or further pressure in case the impression7 or results securedl by one passage through the press should prove insufi'cient or unsatisfactory.
