PHOTOGRAIPI-IIC PRINTING AND TRIMMING MACHINE Application filed July 3,

This invention relates in general to photographic printing machines and has more particular reference to a system for handling photographs whereby the greatest amount of work can be done with fewest operations.

Prior to my invention it has been customary to print the positive from the negative in one frame and then transfer it to another to print the border lines with the use of the mask. In such operation, it is very difficult to align the outline of the print with the lines of the mask. And too, the trimming of the finished prints is both difficult and tedious. With my device the same result is accomplished in one operationpull the handle forwards and push it back and the operation is performed.

The object of my invention is to provide improved means for handling photographic prints in a manner to insure proper alignment of the views with the lines of the border and cut edges of the print paper.

Another object of this invention is to provide a machine simple in construction, cheap to manufacture and positive in operation and which will accomplish a maximum of work with a minimum of energy exerted.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for the purpose of illustrating a practical embodiment thereof, reference is had to the accompanying drawings, in. which like reference characters designate the same parts in the several views, and in which Figure 1 is a front elevation view of the machine, with parts removed.

Figure 2 is a top plan view of the machine.

Figure 3 is an end elevational view with parts in section.

Figure 4 is an enlarged view, parts in section, of one of the details.

Figure 5 is a top plan view of Figure 4.

Figure 6 is a detail view of one of the parts.

Referring now more specifically to the drawings, I show a photographic printing andtrimming machine having a base 33 consisting of a top plate 34, side members 35, a hinged door 36 and a bottom piece 37. To the bottom piece 37 are secured the electric light sockets 38 having the bulbs 39 and pilot 39 The electric current is supplied through the wires 40. A circuit breaker is shown at 43 having the push button 44. The current supplying the pilot 39 is continuous and separate from that supplied to the bulbs 39.

In the top plate 34 are two rectangular apertures 45 and 46. The aperture 46 has depending sides 47 to which is secured the strip 48 supporting the springs 49. Bordering the aperture 46 is the female cutter mem ber 53. Loosely, but snugly, fitted within the aperture 46, and supported by the springs 49 is a glass closure 54. The surface 52 of cloand 58 is opaque, the outer surface 59 is transparent and has printed thereon the border lines 60.

The aperture 45 has a glass cover 62, held in position by the binder 63. The glass cover 62 has an opaque border 64 around its edges extending inwardly to the lines 65, 66, 67, and 68, the surface 69 within said lines is transparent.

To the top plate, and integral therewith, are the base blocks 73 and 74, having the upstanding stubs and 76. The base blocks 73 and 74 have annular recesses around the base of the stubs 75 and 76. Within the recesses 77 are seated the coil springs 78 and 79. Slidably positioned on the stubs 75 and 76 are the guide blocks 80 and 81 of the main supporting plate 82 of the male cutter member 83.

From the top plate extends upwardly the standard 84 having the long sleeve journal bearing 85. Journaled within the bearing 85 is the shaft 86. To one end of the shaft 86 is fixed the operating handle 87, and to the opposite end of said shaft is fixed the cam 88, said cam 88 having attached thereto the smaller cam 89.

\Vithin the top plate is an aperture 93 having pivoted therein the stub shaft 94. Integral with shaft 94 at its lower end, is the washer 95 and intermediate its ends is the stub pin 96.

Secured to the washer 95 is the revolving double frame 97. Loosely fitted around the stub shaft 94 and secured to the frame 97 is the ratchet toothed disc 98. In engagement with the toothed disc 98, and secured to the stub shaft 94 is the pawl 99.

Extending from the front edge of the supporting plate 82 is the bracket 100. The bracket 100 has an aperture 103, into which is secured by means of a set screw, or otherwise, the sleeve 104. The sleeve 104 has a spiral groove 105 which engages the stub pin 96.

Extending from the front edge of the supporting plate 82 are the arms 106, to which is pivoted the platen 107, having the felt lining 108. To the back of the platen 107 are the ears 109 to which is pivoted the toggle link 110. Pivotally connected to the back edge of plate 82 is the toggle link 114. To the top side of plate 82, substantially in the center of same, is secured the anti-friction roller 115.

Extending from back portion of plate 82 is the arm 116 which operates the electric push button.

Seated within a recess in the top side of plate 82 and acting against toggle link'114, is the spring 117.

In operation: The machine is set as shown in Figure 3, the negative is placed on the glass cover 62 and held by the flat spring clip 61, the print paper is placed into the frame 97 the operating handle 87 is brought forward, through an angle of degrees, the cam 88 contacting with the roller 115 forces down, against the action of the springs 7 8, 79, the supporting plate 82. With the motion of cam 88 the cam 89 forces down the toggle links 110 and 114 thereby bringing the under surface of the platen 107 parallel with surface of the print paper occupying the frame 97 and presses upon the frame until said paper contacts with the negative resting on the glass cover. At this stage of operation the arm 116 forces down the push button 44 closing the circuit at 43 thereby turning on the light for making the exposures. As the grooved sleeve 104 makes its descent the shaft 94 turns in the direction shown by arrow in Figure 5, the pawl 99 riding over the toothed disc 98. As the handle 87 is thrown backwards, springs 78 and 79 lift the supporting plate back to its normal position. As the grooved sleeve 104 ascends the shaft 94 turns in an opposite direction, to that made on the descent of said grooved sleeve, the pawl 99 engaging toothed disc thereby revolving the frame 97. Upon succeeding operations as the exposure is being made under frame 97 the cutter 88 trims the print in frame 97 In the first exposure the edges of the paper is shielded from the light by the opaque border 64 but when it has been revolved to be trimmed as the cutter comes down another exposure is made, the glass 54 through which this exposure is made admits the light only at its edges thereby printing the border of the paper in accordance with the design on the glass 54. The glass 54 normally stands just a little above the female cutter member so that the male cutter member holds the paper firmly against the glass 54 before the cutting process starts. As the male member of the cutter presses the glass 54 the springs 49 allow it to yield and by no means interfere with the trimming of the photograph. The border lines and figure may be of any design having such as circular, blocked or clipped corners.
