EASEL FOR PRINTING-FRAMES AND PHOTOGRAPHIC ENLARGEMENTS.

Specification of Letters Patent.

Patented Oct. 13, 1914.

Application filed October 30, 1912. Serial No. 728,696.

To all whom it may concern:

Be it known that I, EMIL FRANKE, a subject of the Emperor of Germany, but having taken out first papers for citizenship of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Easels for Printing-Frames and Photographic Enlargements, of which the following is a specification.

My invention relates to printing frames and supports therefor, and is particularly adapted for use in making photographic enlargements.

As is well-known to those skilled in the art it is necessary to support a printing frame in various positions at different times due to varying conditions, and my easel or support for the printing-frame is especially devised and adapted for the purpose of readily changing the position of the printing-frame and supporting it in any fixed desired position.

My invention is adapted for commercial and studio work-that is it is adapted for prints of all sizes.

In the drawings forming a part hereof Figure 1 is a vertical front view; Fig. 2 a side view showing in outline a larger printing frame than in Fig, 1; Fig. 3 is a section through a portion of Fig. l with the printing frame released from its catch; Fig.

4 is a plan view of the base; Fig. 5 is a section through Fig. 4; Fig. 6 is a view of the brake-mechanism for holding the easel in position on the floor; and Fig. 7 is a detailed view.

In the drawings in which like letters refer to like parts, members 1 and 2 form the base which is made in two sections pivoted on pivot 3 so as to move independently of each other. The movement of the parts is controlled by rack and pinion 7 and 8, the

rack being fixed to the base member 1, and I the pinion 7 being in engagement with the rack and fixed to the shaft 4 held in supports 5 and 9, mounted on'the base member 2. The shaft 4 is provided with a wheel 6, the rotation of which causes the shaft 4 to rotate thereby rotating the pinion 7 engaging with the rack 8 and moving the upper base member 1 around to the right or left as desired on the pin or pivot 3.

1010 are suitable rollers or wheels supported from the base for the purpose of faeilitatng the movement of same across the floor. As shown in Fig. 4, the two rear wheels 10 are provided with brakes shown in the enlarged view in Fig. 6, in which the brake 11 engages with the periphery of the I:yheel, and is held in close contact therewith y a rocking-shaft l2 pivoted on pin 13 so as to be held in engagement with the wheel, or out of engagement of the wheel by the spring 14 as can be readily seen.

15 and 16 are standards, four in number, supported on the base member 1 and arranged in pairs, one pair being arranged on each side of the base member 1, and at suitable distances apart and each pair meeting at pin or pivot 17. Mounted upon the pins 7 as shown in Figs. 1 and 2, is a swingingframe 18 adapted to be held at any desired angle in relation to the base by a rack and pinion l9 and 20. The rack 19 is fixed to the swinging-frame 18, and the pinion 20 is mounted between one pair of the supports 15 and 16 as shown in Fig. 2. This pinion is operated by a handle 21 shown in Fig, 1, the rotation of the handle moving the pinion 20 and causing the movement of the rack 19, thereby moving the swinging-frame 18 on the pin 17.

Mounted in grooves 23 arranged on each side of the swinging frame 18 is a vertically moving frame 22 which is moved in a vertical direction by means of the screw-bolt 24, the thread of which engages with the thread in the bolt 25 fixed to the frame 22. The bolt 24 is operated by the wheel 26 fixed thereto and mounted on the lower part of the swinging-frame 18. Fixed on the vertically moving frame 22 are two guide-ways 27-27 having grooves in which is mounted the horizontally moving frame 28, the movement of which is controlled by the rack and pinion 29 and 30, the rack 29 being fixed to the lower guide-way 27, and the pinion 30 bein rotatably mounted on a plate 31, and provided with a wheel 32, the rotation of the wheel 32 causing the pinion 30 to engage with the rack 29, thereby moving the horizontally moving frame 28 to the right or left in accordance with the direction in which the handle 32 is rotated.

Supported in a circular groove 33, as shown in Fig. 1, is a rotating frame 34 held in place by the plates Fixed on this rotating frame 34 is a rack 36 which engages with the pinion 37 operated by the knob or wheel 38. The pin;' on 37 is loosely mounted the spring 14. The brake 11 is fixed on.

- on the plate 31, and the rotation of the pinion 37 through the means of the handle 38, as will be readily seen, will cause the frame 34 to rotate. Mounted on the frame 34 is a bracket 39 to which is hinged by hinge 41 the printing-frame consisting of glass 42, back 43, hinged to frame 40 by hinges 44, and held in place by buttons 45. The printing frame 42 is held'up in engagement with the rotating frame 34 by means of a little spring catch 46 engaging with the pin 47 on the frame 40. When it is desired to place the paper to be printed upon into the frame, the printing-frame 40 is released from the catch 46, permitted to drop down, and is opened, as shown in Fig. 3, then the butto1r45 is turned so as to release the back 43 which is opened on the hinge 44 permitting the insertion of paper, after which the back is closed and the frame brought up into engagement with the pin 46.

In Fig. 3 I have shown a piece of printing paper 50 between the back 43 and the glass 42 on the printing-frame. Where it is desired to use a large printing-frame, it may be mounted upon the easel as shown in Fig. 2, where I have shown in broken lines, a printing frame 49 mounted on supports 4848 through pins 50-50, which lie in grooves in the supports 4848, and are held in place by the hooks 51, as shown.

From the foregoing description it will be readily seen that the printing frame 40 may be moved into an infinite number of different positions, and be readily held in place therein as follows:-The easel may be moved around on the rollers 10 and held in place by the brake 11. The printing-frame may be arranged at any angle to the base by means of the rack and pinion 19 and 20. The printing-frame 40 may be raised or lowered by means of the vertically-moving frame 22. The printing-frame may be moved to the right or left by means of the horizontally moving frame 28. The printing-frame 40 may be rotated by means of the rotating-frame 34, and the frame may also be moved so as to bring one part of it nearer the enlarging camera by means of the rack and pinion 7 and 8 which operate the moving-bed 1. As can be readily seen from the foregoing, the printing-frame 40 may be positively supported in any position, and the change of position easily accomplished by the simple movement of the pinion, resulting in supporting the printing frame 40 in a positive fixed position.

Having described my invention, what I desire to claim and secure by Letters Patent is 1. In a photographic printing apparatus, the combination of a printing frame, means for supporting said printing frame composed of a swinging frame, a vertically movable frame mounted on said swinging frame,

a horizontally movable frame mounted on said vertically movable frame, and a rotating frame mounted on said horizontally movable frame.

2. In a photographic printing apparatus, the combination of a printing frame, means for supporting said printing frame composed of a swinging frame, a vertically movable frame mounted on said swinging frame, a horizontally movable frame mounted on said vertically movable frame, a rotating frame mounted on said horizontally movable frame, and separate means for moving each of said frames.

- In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

EMIL FRANKE.
