37 Claims. (CI. 95-76) This invention relates to photo-composing machines using a sensitized press plate in con nection with a negative'carrying frame and a lamp.

Such machines are usually of a ponderous type, occupying Considerable space, and contain certain parts, which must function with positive precision, resulting inan'assembIa'ge so expensive to produce as to deter extensive use. The term "negative", as used throughout this application, is to beunderstood as referring to any transparent or translucent substance, as glass, celluloid and analogous compounds, paper and textile fabrics treated to permit the passage of light, etc. etc. bearing images, scribed, written, drawn or deposited photographically, of any objects whatsoever, or having the objects attached in such manner as to be. reproduced by photoprinting.

It is therefore one of the objects of the invention to provide a structure of such simplicity that it can be manufactured at a reduced cost without in any way sacrificing accuracy, convenience and speed of operation, but on the other hand materially enhancing the same.

A further feature is to provide a press plate bed with means whereby it may be moved in parallel toward or from the negative, or the negative frame moved relative to the bed.

Another object is in the provision of means whereby the negative carrying frame and press plate may be independently moved with relation one to the .other while in vertical planes andcombination of parts hereinafter described and illustrated in the accompanying drawings, forming a material part of this disclosure, and in which:--

Figure 1 is a vertical sectional view of a machine embodying the invention, certain parts being in side elevation. Y

Figure 2 is a transverse sectional view taken on line 2-2 of Figure 1.

Figure 3. is a similarsectional view, looking rearward on line 3-3 of Figure 1.

The frame of the machine consists of two hollow transverse base members 15 and 16, respectively at the front and rear, the same being rig' idly connected by side bars 1'1, either integrally or otherwise as preferred.

Rising from the bases, near their ends are pairs of columns 18 and 19 presenting inner parallel faces, the rear columns being slightly higher and of lesser lateral width. a

The rear columns are connected at their up- .per ends by a beam 20, here shown as a rolled angle, the same extending past the columns at both endsunequally, that at the right hand side of, the machine considerably exceeding in' length the extension at the left.

The upright flange of this beam faces towards the front and has secured at its ends a pair of brackets 21 in which is mounted a guide bar 22, as the shaft shown.

A similar beam 23, inc. lower plane, connects the front uprights 18 at their outer top surfaces and is provided with brackets 24 at its ends'to rigidly support a guide bar.25.

The bracket 24, at the shorter, left hand end of the beam, has a raised portion 26 in which is revolubly mounted a shaft 27 screw threaded, except at its, bearings and provided beyond the bearing 26 with a hand-wheel 28 for manual 'adjustment, the shaft being normally driven by a clutch connection 29 with an electric motor 30 carried on a shiftable carriage by which the lamp I mhy be dispensed with and the shaft actuated by the hand wheel alone and further, it is to be understood that any ordinary mechanical equivalents may be substituted by which corresponding results .in shifting the carriage transversely of the machine are attained. r The carriage consists of a rigid, preferably integral structure having four light uprights 35 arranged in the form of a rectangle and single pair of similar uprights 36 spaced therefrom at the front.

The lower ends of the uprights 36- are recessed to produce opposel lugs to straddle a transverse guide rail 37 on the upper surface of the front base member 15 andare held in rigid relation by a flanged brace 38 between the uprights ad.- iacent the rail;-

The. lower ends of the frame uprights 35 are similarly recessed to be guided by tracks 39 extending between the side bars 17 and are held firmly in proper relation by a brace 40.

The uprights 35 and 36v are shown as integral with cross beams 41 at their upper ends, joined 110 at the rear by a transverse beam 42 and at the front by a similar beam as.

Extending angularly outward from the ends of the beams 42 and 43 are bracket bearings 44 and 45 bored to receive the bars 22 and respectively and by which the entire carriage frame and elements'attached to it are suspended, the lower portions being merely guided, not supported.

In order to more effectively guide the carriage on its runways a pair of outwardly and upwardly extending arms 46-47 are attached to uprights and 36, these uprights carrying bearings at their upper extremities to increase the distance between the points of support on bars 22 and 25 respectively and to add strength and firmness to the frame when any strain is imposed thereon.

At the foot of one of the uprights 36 is a bracket 48 on which is an electric motor 49 arranged in an upright position and driving, through a clutch 50, a threaded vertical shaft 51 rotatable in bearings 52 and 53 fastened on the upright 36.

The screw shaft 51 extends above the beam 41 and is provided with a hand Wheel 54; a

sprocket wheel 55 fixed on the shaft 51 below the wheel, drives a chain 56 trained over another sprocket wheel 57 fixed on the upper end of a threaded shaft 58 mounted in bearings 59 and 60 .attached to one of the uprights 35.

The motor 30 is arranged horizontally to rest on a bracketfil fixed on the upper portion of one of the uprights 36 and it is to be understood that the motors, if used, are so controlled as to be run separately or conjunctively as desired.

Both pair of uprights 35 have, on their inside facing surfaces, raised longitudinal ribs extending their full length to act as guides for a vertically slidable lamp housing support, the same .consisting of two pairs of slides and 66, respectively at the front and rear uprights, the same being connected at their lower ends on each side by'cross pieces 6'7 and at their upper ends by beams 68 'havinginreaching undercut faces 69, these beams extending towards the front past the uprights 35.

slidably engaging the elements 69, to extend across from one to the other, are a pair of hanger rails 70 having down-reaching brackets 71 and 72, to supportingly engage a lamp housing 73, the same being preferably a sheet metal casing in the shape of a truncated cone of rectangular cross section disposed on a horizontal axis with its base towards the negative.

This housing contains a lamp, as indicated in Figure 3, of any-preferred type, the same being accessible through a hinged door 74 in its'side; however the lamp may be used without a housing if the sensitized plate be adequately protected by curtains or otherwise.

From the foregoing it is to be understood that the lamp housing, as a unit with the hanger rails I '70, may be movedby hand forward and back without interference with any other part of the structure and irrespective of the height at which it may be positioned. Vertical adjustment of the lamphousing support is provided for by a bracket 75 rigidly fixed on one of the front slides 65, the outer end of the bracket being bored and threaded to agree with the screw 58, which, as has been explained, may be actuated by power orhand, due to the chain andsprocket connection with the screw.

shaft 51. i

The shaft 51 is directly engaged in the-screw threaded portion of a similar bracket 'ld fixed on one of the lateral edges of a negative frame carrier 209, (see Figure 1), the same being slidably engaged between guides on the inner faces of the forward uprights 36 and which obviously will be moved. up and down in substantial synchronism with the lamp housing, the negative frame carrier being described in detail further on.

Extending from the inner faces of the forward columns 18, 18, are two pairs of bars and slidably mounted on the bars isa rectangular frame consisting of sides 81 connectedat the bottom 82 and top 82'. i

The negative frame carrier 200, which may be of. any appropriate size, is placed on a carrier frame and having at its edges a raised, rearward- 1y extending marginal rim 202 provided at its outer edge with light obscuring, marginal cushions- 203 against which the corresponding base edge of the lamp housing seats, making tight contact and preventing rays from the lamps from passing outward other than through the flange on the beam 23 are brackets 87 carrying pivots 88 on which are eccentrically mounted cam discs 89, provided with operating handles 90 by which they may be rotated, the peripheries of the discs being in operative engagement with the caps on the ends of the bars 86 insuch manner as to communicate motion to them, both up and down, and thence, by reason of the arms 85, cause the pins 84 to move in the slots 83', thus moving the frame 8182 forward or back upon its supports 80.

Obviously the disc cams 89 may be replaced by other equivalent mechanical devices, as for instance screws, and it is equally apparent that the frame 8l82 maybe shifted bodily by any other preferred device than that indicated.

Journalled at 92 to the frame sides 81, near their lower ends, are strap brackets 93 connecting the frame 94 of a bed plate 95, the same being supported, when. in a horizontal position, by foldable legs 96 as shown in Figure 1.

When the bed is folded upward in a vertical position between the frame sides it is held by spring clips 97 carried at the upper ends of the frame, the same engaging in corresponding elements 98 on the outer edge of the bed.

From the foregoing it will be seen that the bed plate is movable with the frame 8182 towards .or away from the negative frame, in any position in which it may be.

If motors beused separate controls for each V are provided, all being conveniently accessible .to an operator, who can make final or complete adjustments by the hand-wheels.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as re- "Havingthus described my invention, what I I stationary uprights rigidly held in spaced rela-' tion, an open frame movable between said uprights in a plane parallel with their faces, a press plate carried by said frame, and cam actuated means for moving said frame and plate towards and from the body of the machine.
