' 29 Claims.

This invention relates to improvements in combined motor and manual operated devices for adjusting an object horizontally and vertically with respect to its supports, and more particularly to the negative frame as used in photoprinting apparatus, this application being divided from an application on Photo-composing machines, filed February 24, 1927, Serial Number 171,126, now'Patent No. 1,920,399, dated August 1, 1933. Y

In devices of this character, it is desirable to avoid all tendencies of looseness or back-lash in such structures, for the reason that extreme accuracy is absolutely necessary.

It is also advantageous that the movements be accomplished as rapidly as possible and with a minimum of energy on part of the operator.

It is therefore the purpose of the present invention to provide a structure, composed of spaced 3!} uprights rigidly connected at their lower ends and presenting means for guiding a slidable frame mounted for vertical movement, and to-combine with the frame a plate carrier movable longitudinally relative to the frame.

A further object is to provide a means for'moving a press plate bed in one direction that is separate from other means of movement for moving a negative carrier, so that the movement of either the negative or the plate will not cause movement of the other.

These and other important objects, which will become apparent as the description progresses, are accomplished by the novel and practical construction 'and combination of parts hereinafter described and shown in the accompanying drawing, forming a material part of this dis.- closure, and in which:

Figure 1 is a rear elevational view of a machine made in accordance with the invention.

Figure 2 is asectional view taken on line 2-2 of Figure 1.

Referring to the drawing in greater detail, the numeral 300 designates a base from which rises a pair of columns 301, one of which is provided on its inner surface with spaced, parallel dovetail guides 302 extending its full length.

I Movable on theguides is a rectangular slide 303 having a rearwardly extending rigid bar 304 at its upper end on which rides, at a right angle thereto, a pair of horizontal rails 305' having downwardly extending brackets 306v carrying a lamp housing 307, the slide 303 being provided with a bracket 3'08, passing through a slot in the upright and having a threadedboss 309 at its end engaging a vertical screw 310 journalledin bearings 311 at the top and bottom of the upright.

Extending inwardly from the slide303 in front of the lamp housing 30'? is a spacer 312 to which is fixed a negative carrying frame 313. 5

Secured on the base 300 is a bracket 314 supporting a motor 315 connected by a friction clutch 316, to the lower end of the screw 310, the same being provided at its upper extremity with a hand'wheel 317, so that the screw may be mechanically or manually actuated as desired.

Thus the frame 313 and the lamp housing 307 may be moved in a vertical plane, while the housing 307 may be moved backward and forwar on the track 304.

Fixed to the front of the uprights 301 and extending beyond the same at both sides, is a beam 318 having an undercut guide 319 on its upper surface on which is a carriage 320 engaging a horizontal screw 321 journalled in bearings 322 at the ends of the beam, the screw being provided with a hand wheel 323 at one end for manual operation, and a friction clutch 324 at its other end, connected to an electric motor 325, mounted on a bracket 326 for mechanical operation.

The carriage 320 is provided with upstanding lugs 327 connected by a pair of horizontal hinge pins 328, engaging in leaves 329 secured on the outer face of a plate bed 330 to carry any preferred sensitized positive plate,-the bed being provided with a catch 331 to hold the same in its vertical position.

It will be noted that in the foregoing structure, the negative frame 313 can'be moved in a vertical plane together with the lamp housing 307 and the lamp housing can also move away from the negative, whereas the plate bed 330 may be moved longitudinally, enabling a sensitized plate held thereon to be moved in any position relative 40 to the negative.

The term negative, as used throughout this application, is to be understood as referring to any transparent or translucent substance, as

glass, celluloid and analogous compounds, paper j 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 photoadjustment.

A sensitized plateis secured on the press bed which is then raised by swinging upwardly and held in a vertical position, parallel with the negative frame and the bed and frame mutually adjusted.

Separate controls for each are provided, all being conveniently accessible to an operator, making final or complete adjustments by the hand-wheels.

It will be understood that the relative positions of the negative and blank. positive may be re versed if desired.

It is also to be noted that the vertical screws may be made of such diameter and rigidity as to operate as guides in themselves.

Although the improvements have been described with considerable detail and with respect to certain particular forms of the invention, it is not desired to be limited to such details since many changes and modifications may well be made without departing from the spirit and scope of the invention in its broadest aspect.

Having thus described the invention what is claimed as new and desired to secure by Letters Patent, is:
