. SPECIFICATION forming part of Letters Patent No. 359,725, dated March 22, 1887.

Application filed Apr-i123, 1855. Renewed February 17,1387. Serial No. 227,995. (Modem To all whom, it may concern:

Be it known that I, MiinonLLUs J nwnrr, a citizen of the United States, residing at Cleveland, county of Ouyahoga, and State of Ohio, haveinvented certain new and useful Improvements in Picture-Exhibitors; and I do hereby declare the following to be adescription of the same, and of the manner of constructing and using the invention, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawings, forminga part of the specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle, so as to distinguish itfrom other inventions.

My invention isapicture-cxhibitor, as herei n described.

In the drawings, Figure l is a plan view of the exhibitor with top removed. Fig. 2 is a reverse plan of the inner bottom of the exhibitor. Fig. 3 is a vertical sectional view taken longitudinally through one of the push-slides and looking toward the interior, with a portion of the parts omitted to avoid confusion. Fig. eLis a detail plan view of the actuatinglever and check mechanism. Fig. 5 is a vertical section taken longitudinally through the slide of the preceding view. Fig. 6 is an end view of slide I. Fig. i is a side elevation of the same slide.

A is the exhibitor, having each compartment to at provided at its front with a window, a, said compartments formed by the longitudinally-located slat a. Between the front and rear ends of said slat and the front and rear sides of the exhibitor are the open gateways a, for the passage of the pictures from one of said compartments to the other. Each compartment is furnished with a wedgeshaped fender, a, the office of which is to press the lower portion of the picture away from the end of the compartment that is provided with said fender. Each compartment is provided at the bottom of its outer longitudinal side with a fender, t, adapted to keep the picture from friction with said side. The loop-wires it, near the top of compartments a a", respectively, cooperate with slides H, hereinafter described.

B is the outer bottom of the exhibitor, provided with hand-lever G, pivoted at I), and

with its other end projecting beyond the outer trally-located laterally-projecting cams E and at its extremities the vertical downwardly projecting lugs e.

F are their plate-levers, fulcrumed at f, and having the depending flangesf, bearing against cams E of lever D.

G is a coil-spring secured at its end 9 to the inner bottom, and having its opposite end fastened to lug g in lever in. Said lug passes through lever F and is pivoted in slide H. Said combination of levers H F and coilspring G operates each of the two slides H. Said slides have their outer extremities, 71., bent at a right angle upward and projecting severally through slots h into the exhibitor. Said ends it act as pushers for the pictures.

At the front and rear end respectively of the inner bottom, and near the corners of the same, diagonally opposite to each other, are the two triangular-shaped slides I, having flat projecting flanges 2 in which are longitudinal slots 2 In said slots work the lugs e on lever D. By the combination of said levers D 13 and coil-spring G, slot i, and lugs 6, said slides I are moved backward and forward, with their lugs i, fitting in guideways K. Said slides I also have vertical upwardly-proj ecting lugs i sliding in gutters t, at the front and rear ends of the inner bottom. "When the two bottoms are normally in their place in relation to each other, slot 1) in lever C fits over lug e on D, by means of which said latter lever-is operated by said lever O.

L is a slide moving in recess Z, formed on the inner face of bottom B, and secured by clamps l,'and provided with oblong slot Z in which operates a protruding spring, Z. Said slide has end prongs, Z if, against which lever C works. The object of said spring is to check the backward movement of lever G if it has swung only half-way on its normal are of travel. Passing onto the end of said are it strikes prong Z and pulls thereby the close surface of slide L over spring Z, thereby temporarily suppressing it. Then, on its back ward travel to the opposite end of the are, said lever strikes prong Z, and, carrying thereby slide L in the same direction, thereby releases spring Z", so that it normally protrudes again through slot 2 Said device is to prevent the conflict of moving pictures that would takeplace were lever G to be moved backward before it had completed its full are of normal travel.

The operation of my exhibitor is as follows: Pictures provided with suitable holders, serving for them as bases, are placed transversely and vertically in. the compartments. Each of the two compartments is to be filled with pictures, with their faces toward the front end of the exhibitor. Let the thumb-piece b" of lever G be at theleft-hand end of its stroke. Then by moving lever 0 toward the right hand, as the operator faces the exhibitor, lug t of each slide I engages with the end of apictureholder and slides it along through gateway a* into its appropriate compartment that is to say, the rear slide I pushes the rear picture that is in compartment a" transversely into the rear end of compartment a, while the front slide I pushes the front picture that is in compartment a transversely into compartment a As lever O proceeds in its normal forward course, the office of cams E of lever D, in connection with levers F, is to move front pusher h forwardly into its appropriate slot h sufficiently to permit the picture which is coming into compartment a to pass rearwardly of the pusher, and also to move the rear pusher h rearwardly into its appropriate sloth sufficiently to permit the picture coming into compartment a to pass in front thereof. By the reversal of the movement of lever 0 toward the left-hand, lever D is so moved as to permit coilspring G to move the two slides H in the reverse of their previously-described movement. 13y said reversed movement of forward slide H, its pusher it pushes against the front picture in compartment a thus com pelling all the pictures in said compartment to travel transversely rearwardly; also, by said reversed movement of rear slide H its pusher it pushes against the last picture in compartment (t, thus propelling all the pictures in said compartment transversely and forwardly.

By said operation the pictures in the two compartments are moved along in a hotly simultaneously in their respective compartments, those in compartment a forwardly and those in compartment a rearwardly. In said process the face of the foremost picture in compartment a is presented at the window of the said compartment, and then by the movement of front slide I, as described, said picture is passed transversely through gate a" into comby an endless chain.

\Vhat, therefore, I claim is- 8o the exhibitor that they would have if operated 1. In a pictureexhibitor having front end windows, a, the combination, with two compartments, a a, and a longitudinal partition, a, providing vertical transverse passages a*, respectively, at its ends, of two transverse vertieal slides, I, respectively located in said two compartments at opposite ends of the exhibitor, and operating mechanism D, substam tially as described,connecting the slides, said parts operating in passing pictures in vertical position from one compartment to the other, substantially as set forth.

spectively, in the two compartments, and spring-operating levers F and lever D, substantially as described, connecting said slides, each slide having reciprocating movement longitudinally of its compartment, substantially as set forth.

3. In a picture-exhibitor having two compartments, a a, the combination of two trans verse slides, I, two longitudinal slides, H, and operating mechanism, substantially as described, connecting the same, the said slides H being located-at opposite ends of the exhibitor, respectively,in the two compartments, the two slides I being also located at opposite ends of the exhibitor, respectively, in the two compartments, substantially'as set forth.
