PATENT ROBERT H. JONES, MARCUS B. SMITH, AND LABS J. A. ROSW'ALL, OF

CLARENCE, MISSOURI.

APPARATUS FOR CLEANING PHQTOGRAPHS.

SPECIFICATION forming ,part of Letters PatentNo. 296,578, dated April 8, 1884.

Application filed January 9, 1884. (No model.)

To all whom it may concern:

Be itknown that we, RoBT. H. Jones,

Masons B. SMITH, and Lans J. A. ROSWALL,

of Clarence, couiity of Shelby, and State of Missouri, have invented a new and useful Improvement in Apparatus for Cleaning Photographs; and we do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use it, reference being had to the accompanying drawings, forming a part thereof. 7

Our invention relates to improvements in machines for washing and toning photographs. It consists, essentially, in the combination of the tray or pan secured on a pivotal hearing or support, a motor, and means for communicating the action of the motor to the tray,

as wili be described.

It consists, further, in other improvements, as will be hereinafter more fully described.

In the drawings, Figure 1 is a side view of our improved machine; and Fig.2 is a perspective view of a modification, as will be described.

A suitable standard, A, is provided with a clock-train, B, one shaft of which is provided with a crank-pin, 0, preferably supported on the periphery of and projected forward from a disk, D. This clocletrain may be of any desired form, or may, when so desired, be substituted for by any well-known light motor.

The tray or pan E is held in frame F,which is supported on. pivotal bearings F, as indicated in dotted lines in Fig. 1. A rod, G, extends vertically up from theside of frame F, and is bent at its upper end to form the yoke G, within which the crank O revolves.

In operation it will be seen the crank-pin,

engaging first one and then the other side of the yoke, moves the same from side to side, and causes the tray-support to rock on its pivotal support, as indicated in dotted lines, Fig. 1.

In practice the photographs are placed in the pan or tray, and water or other desired wash is poured in on them. As the tray is rocked on its bearings the water flows from end to end thereof over the photographs, and a thorough washing-or toning, as the case may he, is attained.

Heretofore the operation of washing and toning photographs has been laborious and tedious from the fact that it has been necessary, in the absence of such devices as our invention, to tilt the pan, or cause the water to flow from end to end therein by hand. Our invention, it will be seen, aims to provide means for automatically tilting or rocking the tray.

In Fig. 2 we have shown a shaft, H, journaled between the upper ends of two standards, H. Bars I are secured on the shaft H near its opposite ends, and at right angles to said shaft. The tray is supported on the outer ends of these bars by means of suitable hangers, 1. A motor is secured on one of the standards, H, and is providedon one of its shafts with an armed wheel, J. The arms of this wheel are arranged to engage a rod, J, rigidly secured to and depending from the shaft. This, it will be seen, will rock shaft H and cause the pan to tilt in one direction. A bar, I, is secured on the shaft H, and is connected by a spring, K, with one of the standards. This spring causes the shaft to tilt in the other direction. it will be seen, the desired rocking motion will be given the pan. This machine shown in Fig. 2 is no departure from the broad principles of our invention as described, though in practice we prefer to employ the form shown in Fig. 1. In this form, it will be seen, there By this construction, 1

is no overhanging framing, and consequently no'difficulty in placing and removing the pho- ,tographs from the pan.
