To all 'whom it may concern.'

Be it known that I, WILLIAM C. HUEBNER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in A paratus for Producing oiPwhich the following is a specification.

This invention relates to the production of printing surfaces, such as plates of copper, aluminum or zinc, or'lithographic stones, in which each rinting surface contains a plurints or designs. Such surfaces are desira le in many cases, for instance, when a large edition is to be printed, in which case a corresponding number of-like impressions is pro ucedV simultaneously, whereby the time required for printing the edition 1s correspondinglyshortened, or, when several multi-colored pictures areto be printed upon the same sheet, for instance, in- Wall paper and illustrated newspapers, whenv a correspending number of printing surfaces on the same plate or stone would produce in a single impression all of the pictures on the sheet in the same color. In printing with several colors it is essential to success that the corresponding printi surfaces on the several stones or platesnsould be in exact register, and the object of this invention is to produce an apparatus for producing upon the plate or stone a plurality of impressions in predetermined locations with reat accuracy and in a ver expeditious am? inexpensive manner, suc impressions being afterward repared by any of the Well known methods or printin therefrom.

n the accom anying drawings, consisting of two sheets: lpigure 1 is a plan view of my improved apparatus. Fig. 2 is a vertical section in line 2 2, Fig. 1. Fig. 3 is a fragmentary lan view showing one corner of the movable bed. 4 is a vertical section in line 4*-4, 1. Fig. 5 is a detachedI perspective view of the holdin frame and film 6 is a vertice section in line 6 6, 1, on an enlarged scale. 7 is a fragmentary elevation showing the ratchet an pawl on the carrying rame. Fig. 8 is aV horizontal section in line 8-8, Fig. 6, on an enlarged scale.

Like letters and numerals of reference refer to like parts in the several figures.

The apparatus comprises, briefly stated, a stationaryframe, a bed frame to which the plate or stone is secured and which is preferably movable on the stationary frame, a carriage which is mounted on the stationary frame so as to be movable over the. surface of the plate or stone in one direction, a carrying frame which is movable in the carriage over the surface of the plate or stone at right angles to the direction in which the carriage is movable, a frame to which the film is at tached and which is connected with said carry;

ing frame, the film being provided in relief With the picture or design which is to be placed on the plate or stone, and a pressure mechanism which is mounted on said carrying frame and by means of which pressure is applied to the film and the latter is pressed against the late or stone for p'oducing the impression t ereon after the m has been inked and the position of the film has been pro rly adjusted.

e statlonary frame of the apparatus may be of any suitable construction and comprises, as shown a lower portion A and an uppeportionB, oth extending horizontally. l

C represents the bed upon which the plate or stone D is secured and which is movable horizontally on the lower portion A of the framel which is provided with horizontal guide bars 20 on which the bed is slidably mounted. A suitable mechanism is provided for adjustin the bed on the stationary frame, which mecanism'inay comprise, as shown, rack bars 21 secured to the longitudinal sides of the bed, gear Wheels 22 which mesh therewith and are secured to upri ht shafts 23 journaled in the frame A, an a transverse shaft 24 which isgeared to said shaft by bevel wheels 25 and is turned by Vhand for moving the bed on the frame.

The lower part A of the frame extends horizontally beyond the upper part B so that the bed can be' moved beyond the upper part of the frame for applying the plate or stone to the bed, `or removing` it therefrom, or for other purposes. The stationary frame is preferably provided with a graduation or scale 26 and the bed with a pointer 27 by which the position of the bed and theplate or stone thereon can be regulated.

The upper part B of the stationary frame is provided withr longitudinal guides 30 in which is mounted a carriage E which carries a frame F, movable horizontally in the carriage at right angles to .the direction in which the carriage is movable in the stationary frame. Suitable mechanism is provided for adjusting the carriage, for instance,

l as shown, a screw 31 journaled in the part B of the frame and engaging a nut in the carriage. A scale or graduation 32 is arranged on the frame B and a pointer 33 on the carriage for determining the position of the latter.

The carrying frame F is adjusted on the carriage by any suitable means, for instance, as shown, by two screws 34 journaled in the carriage and engaging nuts 35 on the carrying frame, and a hand-actuated shaft 36 which is geared with said screws by bevel wheels 37. The carriage is providedwithascale or graduation 38 and the carrying frame with a ointer 39 .by which the position of this frame in the carriage can be ascertained.

The carrying frame F- carries a endent frame G which is so attached to the ame F that it is movable toward and from the same, and movable toward and from the plate or stone D upon which the impression is to be made. As shown, the attaching devices com-A prise two pairs of standards 40 41, formed on l the holding frame G, the standard 40 of each pair having on its inner side a vertical ear rack 42 with which engages a gear whedl 43 secured to a horizontal shaft 44 journaled in the carrying frame F. By turning these gear wheels simultaneously the holding frame is raised or lowered. The shafts of these wheels are provided on the outer sides of the carrying framey with hand wheels 45, and ratchet wheels 46 and pawls 47 are provided on the carrying frame for engaging the ratchet wheels and holdin the holdingframe G in the raised position wen it is desired to expose the underlying surface of the plate or stone.

The holding frame contains a frame H to which the film 1 is secured. The film frame H is detachably secured to the holdin frame,

referably in such manner that tfie 'lm ame can be swung up in the holding frame to expose the film and can also be removed from the holding frame. For that purpose the film frame is provided with hinge lugs 50, each arranged between a pair of lugs 51 52 on the holding frame, and .the inner lug 51 of each pair is provided with a retractable hinge pin 53 which normally projects into the lug 50 of the holding frame, as shown in Figs. 5 and 6. 1n this position of the parts the film frame H can be swung on its hinges. By withdrawing the hinge pins from the lugs of the film frame l-l the latter is detached from the holding frame G and can be lifted from the latter. W hen it is desired to examine in turn Vthe impression on the plate or stone, or the film, or to mk the film, it isfiicient to swing the film frame u on its hin es, but when it is desired to c ange the fi 1n it is l more convenient to remove the film frame l from the holding frame.

The two hinge pins are preferabl operated simultaneously by suitable mec anism, for instance, as shown, by rods 54 connecting ithe two pins with an intermediate hand wheel 55 which is journaled in the holding iframe G. The hinge pins are preferably I held in engagement with the lugs of the film frame by a spring 56 applied to said wheel and the releasing) movement of said wheel may be arrested y a stop 57.

rlfhe carrying frame F carries in addition to l the described aas by which the fum is supported a suita le mechanism by which pressure is applied to the film after the latter has been ad usted tostand exactly over that part of t e plate or stone u on which the impression is to be made. T iis pressure mechanism is preferably constructed as follows:

60 represents a cross head which is hinged at one side to the carrying frame F by hinges 61 and detachably secured at the opposite l side to said framel by any suitable fastening devices, for instance, locking pins 62 )assing through lugs 63 on the cross head andlugs 64 `on the frame. 65 represents the pressure l platen which is operated by a hand screw 66 working in the cross head and serves topress the film against the plate or stone. This I platen is preferably guided by rods 67 which i slide in openings in the cross head. l/Vhen the latter is locked to the holding frame, as shown in full lines in Figs. 2 and 4, the platen stands over the film and can be operated by the screw to press the film, which is iiexible, against the plate or stone. When it is desired to examine the impression so produced, or to ink the film, the platen is swung L on its hinges away from the film, `as shown in dotted lines in Fig. 2, and the film frame is t swung up on its hinges, as described. The film may be of any suitable construction and material and may be produced in any suitable manner. 1t is attached to the l film frame and by means of the latter to the l holding frame and after having been inked 1 and adjusted to the desired position with ref- 1' erence to the plate or stone an impression is l made upon the latter in the desired (position. l The film is then adjusted to stan succesi sively over the different portions of the plate l or stone upon which similar impressions are l, to be made and these portions are noted by reference to the scales provided on the stationary frame and the carriage. `When the plate or stone has been so provided with the from the bed and another plate or stone for the next color is secured/to the same. The film for this color' is'now substituted for the' film previously used and the plate or stone is provided With im ressions from this film in exactly the positions in which the impressions for the first color ".vere produced u on the first plate or stone, which can be rea ily done by adjusting the film to the several positions by reference to the scales provided on the carriage and the styationar frame. Corresponding impressions pro uced on successive stones or plates in this manner Will register correctly.

If it is desired to provide the plate or stone With a plurality' of printing surfaces which differ from each other, the operation is carried on in the same way but different films are applied to the holding frame for each impression. The ,prints on the same plate or stone are different from each other in this case but the corresponding prints on the several plates or stones are alike and in correct register. Where the same film is required to be applied and removed a number of times it is advisable to have a separate film frame H for each film, so that the film is not required to be detached from its frame.

After the impressions have been so made upon the plates or stones the are fixed upon the plates or stones by any o the Well known methods of etching employed for that purpose.
