DISH-WASHER.

Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed February 18, 1908. Serial No. 416,519.

To all whom it may concern:

Be it known that I, JOEL M. GILBERT, a citizen ofthe United States, residii'ig at \Vest Somers, in the county of Westchester and State of New York, have invented certain.

new and "useful Improvements in Dish- Washers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to dish washers and is more particularly an improvement over my former patent #867968, issued the 15th day of October, 1907, and my object is to provide -operated means for suspending a tray es in position to be immersed in water. A further object is to provide means for reducing friction between the parts of the washer. I

"A still further'object is to provide a cover for the tray, whereby the water will be prevented from splashing over the sides of the washer and a still further object is to pro'vide means for disposing the outer end of the operating lever insuch position that the tray 7 containing the dishes may be readily introduced or removed from the washer.

@the'r, Objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings which are made a part ofthis application, Figure 1 is a perspective view of my improved washer complete. Fig. 2 is a perspective view of the dish tray and supporting frame removed from the washer. Fig. 3 is a detail elevation of a portion of the operating lever, showing the outer end thereof elevated. Fi 4 is a detail elevation on an enlarged scale of an anti-friction device. Fi 5 is a detail perspective view of a slight y modified form of supporting spring. Fig. 6 is a perspective view of the cover removed from the washer. Fig. 7 is a perspective view of a slightly modified' form of operating lever, and, Fig. 8 is a detail erspectiveview of a slightly modified form 0 anti-friction device.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indi cates the tank or body ofmy improved dish washer, in which is adapted to be disposed a tray 2, said tray being smaller in diameter than the diameter of the body 1 and issu ported by means of a circular frame 3, t e

outer face of the tray2 having lugs 4 thereon adapted to extend over and engage the upper edge of the frame 3 and limit the downward movement of the tray in the frame. EX- tending upwardly from the frame 3 and at diametrically opposite sides thereof, are cars 5, to which are pivotally secured the lower ends of standards 6, the upper ends of said standards being in turn pivotally secured to an operatmglever 7. The lever 7 is preferably constructed of parallel bars and said bars are divided into sections 8 and 9, the

sections 8 being hingedly secured to the sec-' tions 9 by introducing pins 10 through the overlapping ends of the sections'S and 9, said pins also extending through the upper ends of the standards, thereby pivotally securing the standards to the sections 9 and to limit the downward movement of the sections 8, the ends of the sections 9 to which the ,sections 8 are secured, are tapered downwardly as shown at 11 while that portion of the sections 8 engaging said tapered ends are oppositely tapered as shown at 12, thereby forming a stop for the sections 8 in their downward, pivotal movement. The forward ends of the sections 8 are connected together by means of a bar 13, which bar forms a handhold whereby the lever may be readily operated while the rear ends of the sections 9 are pivotally mounted upon a shaft 14 carried tions, the joined ends of said sections being hooked around a rod 17 carried by the arms 15, while the free ends oi said parallel sections are hooked around a similar rod 18 carried by the parallel sections 9, said springs being so arranged that downward pressure on the lever 7 will exert. tension on said spring, .the tension of said springs being such as to normally retain the frame and tray at the upper edge of the body until downward ressure is applied to the lever 7 and 1t Wlll be readily seen that when the frame and tray have been lowered into the body and downward pressure removed from the lever 7, said 'saidtrack-ways having longitudinal gutters,

the Surfaces of which are curved, with which are adapted 'to engage anti-friction rollers 20 carried in brackets 21 on' the outer face of the frame 3 the peripheries of said rollers being likewise curved to fit the contour'of the gutters and as said rollers are rotatably mounted in said brackets, it will be readily seen that they .will travel longitudinally of the trackway 19 with a minimum amount of friction and that they will at all timeshold the frame at a uniform distance fromthe wall of the tank. p

' The object in pivoting thesections 8 and 9 of the lever 7 is to permit the sections 8 to be moved upwardly and -rearwardly, whereby the tray may be readily introduced into or removed from the frame 3 and in order to hold said sections 8 normally fixed with the' sections '9, the pivoted ends of the sections 8 are provided with semi-circular spring arms 2-2,.the freeends of said arms extending into engagement with the outer faces of the sections 9 and are provided with tapered fingers 23 which are adapted to snap over the upper edge of the sections 9 when the sections 8 are t Y rollers 20, a slide bar 20 may be sedured to lowered and by pressingoutwardly on the free ends of the spring arms, the fingers are moved from over the sections 9, when the sections 8 may be'drawn upwardly and as soon as the fingers have passed below the sections 9, the spring arms will press against the sections 9 and hold the sect-ions 8 in their elevated position.

If desired, a hood or cover 2e may be placed over the tray 2 to prevent the water from splashing over the upper end of the body 1 when the tray is lowered into the water,

said hood being preferably conical and seourely held in position over the 'tray by means of spring tongues 25 engaging the peripheral edge of the tray, the outer ends of said tongues having curved terminals 26 adapted to snap over and bind upon the peripheral surface of the tray and if desired, the hood may be suspended by means of links 27, which links are secured at one end to the hood, while the opposite ends thereof are pivotally secured to the sections 9 of the lever 7 and when the hood is so mounted,'it may be swung upwardly and rearwardly, as shown in Fig. "1 when the tray is being introduced into or removed from the frame, or if desired,

the links 27 maybe dispensed with and the hood set' in position over the tray or removed ards 6, practically the same result will be therefrom and set to one side when the wash-- ing process is completed. In Fig. 5 of the drawing I have shown a slightly modified form of'spring and in this instance a stirrup 28 is extended downwardly *0 from the arms 15 and a plate 29 extended across the ends of the sections 9 at a point immediately above said stirrup, the plate 29 carrying a plunger 30, the lower end of which 1 extends through the lower end of the stirrup '7 28, a spiral spring-31 being introduced around the plunger. between the plate 29 and lower end of the stirrup 28 so that when the lever 7 is lowered, the tension of the spring 31 will be increased.

In Fig. 7 of the drawings, I have shown a slightly modified form of operatingleve r and instead of pivotally mounting the two sections of the lever together, the sections 8 -are telescopically mounted in sections 9*, the ends of the sections 9 receiving the sections '8, having any suitable form of ball-bearings 9 and by terminating the sections 9 adjacent their pivotal connection with the stand- 9U accomplished by moving the sections 8 inwardlyuntilthe bar 13 thereof engages the ends of the sections 9*, as when the sections 8 are thrown upwardly and rearwardly and instead of curving the sections forming the lever outwardly to conform to the peripheral contour of the frame 3, the sections 8 and 9 are straight throughout their length and the standards 6 bent inwardly and upwardly at their upper ends to engage the sections 9*.

Instead of providing the anti friction the peripheral face of the frame 3 by means ofa bracket 21 and by forming the slide bar 20 with a curved outer face and a gutter 32' in the face of the track-way 19 to receive the slide bar, the friction will be reduced to substantially the same extent as when theitntifriction rollers, are employed.

In operation, the tray 2 is dishes and introduced into the fi;aine 8, after which the hood is introduced over the upper end of the tray and the proper amount of water to thoroughly cleanse the dishes, placed in the tank 1. The lever 7 is then moved upwardly and downwardly raising and lowering the tray in the tank 1, this operation causing the water to pass through theseries of openings 33in the tray 2 and between the dishes placed in the tray, -the cempression 12 0 caused by raising and lowering the tray in the tank causing the water to thoroughly cleanse the dishes as it is forced between the v same. VVhen the dishes have been thoroughly washed, the outer end of the lever 7 is thrown upwardly or moved inwardly as shown in Fig. 7 and the tray containing the dishes removed from the frame and dried It will thus be seen that I have previded "if I very cheap and economical form of dlSh filled with the 110 washer and one that may be readily and easily operated and it will further be seen that (parts of'the washer may be quickly dispose in position to introduce or remove the tray when desired.
