Specification of Letters Patent. Patented J une 17, 1919.
Application filed September 28, 1918. Serial No. 256,080.
To all whom it may concern:
- Be it known that I, DONALD RoBER'r NAPIER TAYLOR, a subject of the King of Great Britain and Ireland, residing at 435/7 Kent street, Sydney, State of New South Wales,
' printing plates such as used in color print- I will describe one form of apparatus eming the hand wheel M. The means employed to effect the adjustments may be varied according to the fancy of the designer and may consist of screws, worms and worm wheels or pinions acting directly upon racks; in either case the handwheels L, M Wlll be used to operate the working parts. A lever arm N, pivoted at the point n, carries a screw N, at the lower end of which is a A frisket frame 0 is I presser foot- N hinged to the surface of the table at the point 0,-0, alongside the aperture K. The frisket frame consists of a frame in which is a pane of glass or other suitable transparent medlum; its function is to register position marks 'on' the plate G and on a sensitive first printing plate, so that duplicate plates,
bodying my invention and will then pointout the novel features thereof in claims. 1 In the accompanying prints, Figure 1 is a view showing in bottom plan one form of apparatus embodying my invention.
Fig. 2 is a longitudinal sectional view [taken on the line 22 of Fig. l.
Fig; 3 is a transverse sectional View taken on the line 3-3 of Fig. 1.
Referring specifically to the drawings, J designates a rectangular table having a plain upper surface and provided at its center with an aperture Krecessed into the sur face; in the recess will be a thick sheet of late glass it. Vertically below the aperture K is a trough K containing mercury tubes K that are adapted to glow with light, when an electric current is switched on. Between the trough K and the aperture K, is a shutter K that will be manipulated by a rod and handle K. Transvrsely upon the sur- I face of the table is a clamping frame L which may be adjusted transversely by manipulating the handwheel L.and screw or rack L and may be adjusted longitudinally by manipulating the handwheel M. .The
transverse screw L wh'nh is carried by'the l adjustable frame L has a threaded engagement with the transversely adjustable frame member L The frame member L which is adjustable transversely of the table is provided at intervals with clips or clamps L for engaging a sensitized plate Z. The longitudinal screws L are connected by worm gearing L with an operating shaft L carry- (as may be required) shall occupy the same place over the aperture K that was occupied y the first plate. This is indispensable in color printing. Except when the frisket frame is turned over to overlie the aperture K, it will lie in a recess in the surface of the table, as shown in Fig. 2.
ed by manipulating the handwheels L, M.
The single or manifolded image photo'- graphed upon the sensitive plate G having been developed and fixed, in the usual way,will henceforth be referred to as the original image, in order that the sequence of operations, hereinafter described, may be intelligently grasped.
The original image on the plate G will be I laid on the plate glass 70 in the aperture K, and, by means of micrometer screws/l2, adjusted so that the marks upon it shall coincide with the register marks on the 'frisket O; the surface of the plate G, on which is the protographed original image, must be flush with the surface J of the operating table. The means adopted to adjust a plate in the recess, over the plate glass 70, as, e. g.
micrometer screws, so that marks upon the plate shall be made to coincide with the registered marks on the frisket, are well known to, and understood by, every mechanician. A suitably prepared printing plate, block or stone Z (the position of which is shown by dotted lines in Fig. 1). will then be 'se-' cured to the clamping frame L and properly adjusted above the original image on thev plate G, that had been laid on the plate glass is in the aperture K; this will be efi'ec-tlVhen the printing plate Z has been accurately adjusted and positioned, the presser foot N on the lever arm N, will be swun lOO of the printing 'plateZ, immediately above it, to the action of the light rays, the appa ratus being then left until the original image has been, photographically, printed upon the sensitized'surface of the printing plate Z. After the necessary lapse of time, the shutter Ki'will be closed, or the light switched off, the presser foot N will be released and swung back from the aperture K,
leaving the printing plate -Z free to bemoved in any. direction. If the desired direction of movement of theplate Z be transversely the table, this will be effected by manipulating the handwheel L, if it be longitudinal, it will be effected by manipulating the handwheel M the object being to expose a fresh surface" of the sensitized printing plate Z above the original image on the plate G in the aperture, so that another duplicate of the original image may be, photographically, printed-upon the newly exposed sensitized u surface of the printing plate Z, alongside the transfer that had already been made. In
this way, if the original image on the plate G comprised a series of ten identical photographs, and this series of ten was printed ten times upon the sensitized surface of the printing plate Z one single pull in a'suit able printing or litho press would produce one hundred identical images of the original photographed image that was inserted into the camera. If the original image on the plate G consisted of one photograph only, and this photograph was multiplied ten times upon' the. sensitized surface of the printing plate Z, the issue from the rinting press would be ten images for one pull. A
When the-whole sensitized surface of the printing plate Z has been consecutively printed with transfers of the original image, or the desirednumber of transfers has been made, the printing plate Z will be removed from the table, the images printed uponsensitiz'ed surface will be developed and fixed and the plate Z will be handed to the lithographer to be prepared for printing op.- erations in a manner that .is well understood. If duplicate plates are required, as
e. g., in color printing the fresh plate will be adjusted above the original image on the plate G in the recess by means of the regis-, ter marks on the frisket O and the hand- "wheels L, M, so that the transfersprinted on'the fresh plate Z shallcoincide in every particular with the transfers printed upon the first plate Z the operation of printing transfers upon fresh plates Z being repeated as often as may be necessary.
, I .claim 1. A printing apparatus comprising a table having an opening formed therein, a trough in said opening adapted to receive a negative plate, a source of light below said opening, a registering device hinged to the table and adapted to swing over said opening, -a n 1ovable frame adapted to carry a sensitized plate, means for moving said frame longitudinally and transversely of said opening, and a presser foot pivoted to said table and adapted to bemoved over said opening.
A printing apparatus comprisinga table having an opening therein to receive 'a negative plate, a source of light below the opening, a main frame, a clamping frame movable over the table, a worm shaft journaled in the main frame and disposed over the table, a pair of threaded sleeves on] the shaft and connected to said clamping frame, a pair of worm shafts below the table, threaded sleeves surrounding portions of the pair of worm shafts and connected to said main frame, and means for actuating said shafts.
3. A printing apparatus comprising a table having an opening formed therein, a
trough in said opening adapted to receive a negative plate,a source of light below said opening, a clamping frame adapted to support a sensitized plate, means below the table for moving said frame longitudinally of the table, and means above the table for moving the frame transversely thereof.
4. A printing apparatus including a table having an opening formed therein adapted to receive a negative plate, means-for ad-' justably supporting a sensitized plate above said opening, and a registering device comprising a frame hinged to the table at one' side of said opening, and a transparent plate in the frame having position marks thereon,
said frame normally lying upon the table at one side of the opening and the hinge connection between the frame and the table be:
ing at the inner side of the frame when the latter is in said position upon the table and permitting the said frame to be swung over the opening.
In testimony whereof I have signed my name to this specification in the presenceof two subscribing witnesses.
