To all whom t may concern:

Be it known that I, ARTHUR K. TAYLOR, a

citizen of the United States, and resident of Baltimore, Maryland, have invented certain new and useful improvements inv Methods ofand Apparatus for Preparing Registering Impression-Forms, of which the following lis a specification.

The present invention relates to an improved method of and apparatus for use in A making up registering forms for Kuse in printing, embossing, dieing and creasing lithography or similar work. i

The object of the invention ,is to provide a method and means by which any impression form inaybe'quickly prepared with all of the movable or separate elements thereof properly Ipositioned to insure 4correct registry of impressions therefrom with or in impressions from other forms.

The invention is particularly adapted for use in preparing forms for multi-color printing, or positioning printing forms, plates, cuts or transfer impressions, or for positioning dies for embossing, cutting or creasing paper or other blanks, which have been or are intended to be printed.

The term impression form as herein einployed is intended to include any holder, container or base adapted to receive one or more movable members and retain the same in any adjusted position so that limpressions can, by aid of a suitable press,l be obtained t therefrom.

In the accompanying drawings, Flgure 1 is a. perspective view illustrating, more or less conventionally, an apparatus including an embodiment of the invention; Fig. 2 is a transverse vertical sectional view; Fig. 3 is a plan view substantially on the line 3-3 of Fig. 2; Fig. e is a view on an enlarged sca-le partly in section on the line 4--4 of Fig. 3;

Fig. 5 is a detail view of a portion of the' automatic means controlling the illuminating devices; Fig. 6 is a sectional view on the line--o of Fig. 5; Fig. 7 is a diagrammatic view of the electric circuits for the illuminating devices; Fig. 8 illustrates a slightly modiiied form of apparatus; Fig. 9 is a transverse sectional view illustrating a slightly modiiied form of illuminating means; Fig. 10 is a vertical sectional view substantially on the line l0-10 of Fig. 9; Fig. 11 illustrates a modified form of lens system.

Referring to the drawings 1 designates an imposing table or support for an imposing stone on which the impression form 2 is sup orted while bein made up. On or about t e table 1 is provided a rectangular shaped frame, comprising corner posts or uprights 4 connected at their upper ends by suitable side and end members. Said frame includes parallel track or guide rails 5 eX- tending throughout the length of the frame and each provided on its upper surface with a rack 6. said'rails 5 is mounted a carriage comprising side members 7 which rest Y on and are supported by the frame rails and are suitably connected at their ends. In bearings 8 projecting from opposite ends of one of the carriage rails 7 is mounted a shaft 9 provided at its ends with hand wheelslO and also having pinions 11, which engage the racks 5L on the frame. By means of either hand wheel 10, therefore, the carriage can be moved longitudinally of the supporting frame over the table 1.

On the carriage is mounted a projecting apparatus which as shown is carried by a slide 12 that rests on the horizontal surfaces of the side members 7 of the carriage.- One of the carriage members 7 lis preferably 'provided with an upwardly extending rib 13 and the slide12 is correspondingly grooved adjacent one edge to engage this rib so that the slide will be caused to move in a straight 'line and be held from lateral turning or twisting. Through an aperture in the slide 12 extends a tubular lens holder 14 within which is arranged a lens system adapted to project upon the, table, below the lower end of the tube, an exact image of an object positioned above the upper end of said tube.- lt will be evident that the invention in this regard is not dependent on any particular arrangement or number of lens elements. Fig. of the drawing illustrates `an arrangement which has been by .practical experience found to be very satisfactory, the same comprising a double convex lens 15 arranged substantially midway of the length of the tube 1li and two prisms 16, 17, arranged resuit-able means, the outlines of. the space or spaces to be 'occupied by the -several memy bers of an impression form ormay be a primary impression form, for example. A plate or sheet of Celluloid or'other trans- ,parent material may be used and the term sheet ashereinafter employedin this connection is intended to include any device, means or object, the projection of an image of more or less of which, as hereinafter de'- scribed, is. adapted to enable the operator to 'properly position a movable impression s urface or member within the form 2 on the table 1. 'As shown, the frame is provided -with a transparent top 19 on which the sheet 18 rests. The top 19 can be formed of a' single plate of glass adjustably supported at its edges by the side and end members of the frame.

The slide 12 which directly supports the projecting devices is adapted to move on the carriage between the members 7 thereof or in a direction transverse to the direction of its movement with the carriage over the table 1 and relative to the sheet 18. By this .arrangement it is possible to readily position the projecting lens system so that an image of the necessary part of any section of the sheet 18 will be projected on to the form 2 and a relatively small device only is required for working with forms of large-size.

It is preferable to exclude from the chamber or space within the supporting frame between the carriage and the table 1, all light except that which passes through the tube 14. As shown each said member 7 of the carriage is connected with one end of an opaque curtain 20 that extends from one side of the supporting frame to the other; and

22 is provided for inclosing the sides of the space between the table 1 and carriage supporting rails 5. As shown-this side screen or curtain extends over horizontal strips 23 attached to the end posts of the supporting` frame above the carriage, said strips being of sucient width-to cause the curtain 22 at the sides of the frame to be carried out, be-` yond the carriage manipulating wheels 10 so'that the operator standing within said curtain can readily engage the adjacent Wheell 10 to move the carriage as desired.

' rllhe carriage may be*l provided with any suitable means for enabling the operator to meeste adjust the slide 12 and "projecting means area of the sheet 18 that is to be projected on to the form 2. For this purpose a series of electric lamps and lreflectors may be supported by the carriage relatively close to the support for the sheet 18. For example, as

shown, the carriage may be provided adjacent its ends with uprights 7EL A'connected at vtheir upper ends by cross bars 7b on each of which is arranged a'series of concave reflectors 25'each having therein an electric lamp, the .reectors being so positioned that the rays of light from the lamp will be thrown against the sheet 18 at the proper angle to best illuminate the surface thereof. As will be evident it is only necessary or desirable to project on to the form 2 an image of a relatively small portion of the total area of the sheet 18 and it is of course unnecessary and undesirable to illuminate portions of such sheet that are not necessary for the particular work inhand. Therefore means are provided by which the lamps carried by the carriage are lighted in groups depending on the adjustment of the slide 12 andl projectingv tube'14 relative tothe carriage.4

' rlhe lamps at each side of the carriage are connected series and a commutator or switch moved by the slide 12 is provided for bringing the desired lamps into the circuit. The switch or commutator shown comprises a bar 26 of insulating material which is mounted ina channel formed in one of the uprights 7a of the carriage and connected with a rack 27. rlhrough the bar 26 extend a plurality of contact pins 26each adapted to electrically connect contact plates 28, 28a.,

of lamps positioned at opposite sides of the carriage. In practice it has been found sufposition the projectj licient to provide four of such circuit closers.

so that in each adjustment of the slide 12 and projecting tube 18, eight of the lamps .will be operative, the others being vout of service. To automatically move the rack 27 and circuit closing device 26, said rack is engaged by a'pinion 29 at one end of a short shaft which is provided at lits opposite end with a bevel pinion 8O withfwhich engages a corresponding pinion 31 on the upper end of a shaft 32, the lower end of which is provided with a pulley or sprocket engaged by the slide actuating member 24. To prevent the illuminating means from unduly heatrasante Fig. 8 illustrates a slightly modied formA of tbe apparatus herein before described. ln this embodiment of the invention the carv riage 40 supports both the 'projecting tube or casing 4l and thevsheet containing the registering detail, said sheet being in this embodiment of the invention connected at its ends to `rollers 42, 43, and being adapted te lie Wound from one roll to tlie other as carriage )erts 50 on tlie ira-me. rl`he.operative l of the sbeet 44, as well as tlie proineans 4l and illuminating devices 45, are inclcsed in a casing 46 having opening 4? in alinement ivitli tbe projecting casing 4l. if; reiector 48 is suitably mount- K ed on the carriage to direct the image proscreens such as 21.

The slide 51, as shown, ex?

tends through a slot in one Wall of the casing 4S and the opening 47 in said Wall is made in tlie form of an elongated slot which if desired, be closed throughout its length except that portion directly opposite tbe projecting casing 4l by curtain-like The slide 51 and carriage 40 are suitably apertured to permit'tlie rays of light striking the reflector v48 to tall upon tbe table i.
