' Application filed April 19, 1895. Serial No. 546,313- (No model.)

To all whom it may concern.- copies. The pressure-board is made, prefer- Be it known that I, WILLIAM H. LEWIS, a ably, of two sections 6 7, which are hinged tocitizen of theUnited States, and a resident of gether by hinges 8, as usual. One of these Huntington, in the county of Suffolk and State sections, as 6, is made as narrow as possible 55 of New York, have inventedcertain new and in order to allow of the inspection of the useful Improvements in Photographic-Printcopies by opening section 7. The piece at ing Frames, of which the following is a specione end of frame 3 is cut down, as at 9, and

The latter of these consists of the the like. These frames consist, usually, of a curved and bowed spring cam-arm 10, which rectangular frame, a pressure-board made of is fastened at one end, as by screws 11, to two sections hinged together, and springsection 6, and the locking and clamping lever I5 clamps which unite the two. There are ob- 12, which is pivoted by means of the screw or jectionable features about these prior printbolt 13 to the end piece of frame 3. This ing-frames, such as the liability to relative spring-lever 12 is provided with a stud or pin displacement of the negative or drawing and 14:, which projects below the same, as indithe copy when the operator opens one section cated in Fig. 2, and coacts with the cam 10 to 2c of the pressure-board to inspect the copy or push the section 6 firmly against the frame 3 copies, for severalcopiesare sometimes made and the shoulder 4, the resiliency of the cam simultaneously, 85c. 10 and lever 12 permitting of variations in It is an object of this invention to be able the thickness of the copies and originals. to inspect the copies asoften as desired dur- The cam 10 is bowed up (see Fig. 2) to give it 7 25 ing the printing process withoutthe possibilroom to spring, and stop 15 on section 6 preity of the relative displacement of the copies vents it from bending sidewise. The end and the original, be it a negative or a drawpiece of frame 3 is recessed at 16 for stud 14.

The section 7 is provided hereinafter more fully appear. with the spring-clamp 17 and frame 3 with The preferred form of the invention is the cars 18, as usual. shown in the accompanying drawings, form- The counter consists of the toothed number- 5 ing part hereof, wherein wheel 22, which is pivoted to frame 3 adja- Figure 1 is a back view of my improved cent lever 12.

Referringtotheformoftheinventionshown as in Fig. 3, and which passes underneath 5 in the drawings, the numeral 3 marks a rectthe same, as in Fig. 4, the directions of moangular frame, of wood or other suitable mation being indicated in each case by an arterial, which is provided with shoulders 4 on row. It will be observed that the described the inner edge thereof to support the negaconstruction is such that the pawl 25 becomes tive or glass, as usual. The frame 3 is prodisengaged during the forward motion from 50 vided with the usual recess 5 for facilitating the teeth of the number-wheel 22 when it has the removal or opening the same to inspect turned said wheel one tooth. Such construction permits of greater latitude of motion of lever 12 than would be the case were this not so. It is during the return, as in Fig. 4, that wheel 22 rocks on its pivot by virtue of the spring-washer above described.

Of course the common spring-pawl or spring-pressed pawl may be used, instead of the pawl or toe 25 above described,on the lever 12 to operate the counter.

The operation of the foregoing is as follows: The pressure-board is removed by opening lever 12 and clamp 17. The negative, &c., are put in place, as usual, after which the board is replaced and lever 12 turned into place. This lever and its toe or stud 1 1 firmly-lock the section 6 to the frame and the lever clamps it in place. This of course means that the negative and prints are firmly held at that end. Clamp 17 is now turned into working position. If it be desired to inspect the prints at any time, clamp 17 is opened and section 7 is turned back and the inspection made. When the negative is to be removed, the clamp 17 and lever 12 are both turned, and it is at this time that the counter is turned one tooth, the detent acting as a pointer. Thus the number of prints made is automatically tallied.

The reference 26 marks a glass plate, (negative,) and 27 marks a copy or print from the same. Reference 28 marks a suitable packing, as a rubber tube, between sections 6 and 7 for excluding light.

A card, as a, may be placed under cam 10 to receive the number of the negative in the frame.

It will be observed that by the described construction the locking and clamping mechanism locks and clamps one section of the pressure-board or back to the open frame by pressure exerted in two directions at right angles to each other, holding it firmly against the shoulder of the open frame and likewise against one end of such frame.

\Vhile the foregoing embodies the preferred form of the invention, it is obvious that many changes may be made in details, parts of combinations, and by inversions without departing from the invention.

What I claim is 1. In a printing-frame, the combination of the open shouldered frame, the sectional pressure-board, a cam, and a lever having a toe or stud, one of said cam and said lever parts being on the board and the other on the frame, whereby one section of said board is firmly locked to said frame by pressure acting in two directions, substantially as and for the purpose described. 1

2. In a printing-frame, the combination of the open shouldered frame, the sectional pressure-board, a cam, and a spring lever having a toe or stud, one of said cam and said lever parts being on the board and the other on the frame, whereby one section of said board is firmly locked to said frame by pressure acting in two directions, substantially as and for the purpose described.

3. In a printing-frame, the combination of the open shouldered frame, the sectional pressure-board, a cam on one of said sections, and a lever pivoted on said open frame and having a stud or lip for coaction with said cam, whereby said section is firmly clamped and locked to the frame, substantially as described.

4. In a printing-frame, the combination of the open shouldered frame, the sectional pressure-board, a spring-cam on one of said sections, and a spring-lever provided with a too or stud and coacting with said cam to firmly lock and clamp said section to the frame by pressing the same in two directions, substantially as described.

5. In a printing-frame, the combination of the open shouldered frame, the sectional pressure-board, a spring-cam on one of said sections, and a spring-lever pivoted on said open frame and having a stud or lip for coaction With said cam, whereby said section is firmly clamped and locked to the frame, substantially as described.

6. In a printing-frame, the combination of the open frame and the pressure-board, with a pivoted clamp, a pivoted counter, and a pawl on said clamp for operating said counter and disengaging therefrom when the counter has been turned one space or interval, substantially as and for the purpose described.

7. In a printingframe, the combination of the open frame, apressure-board, the pivoted clamp, a counter mounted on a spring to rock, and a pawl or toe acting on said counter to turn it and to pass it, substantially as and for the purposes described.

S. In a printing-frame, the combination of the movable clamp, the counter, a cupped springwasher under the counter, and a toe on the clamp which turns the counter as the clamp moves one wayand which tilts the same as the clamp moves the other way, substantially as described.
