Claims.

Y This invention relates generally to devices of resilient material for attachment to the edges of Washing trays, 4particularly portable metal trays,

4such as are employed in beauty parlors for the .5 washing of hair.

It is an object of the invention to provide a device of the above character which will have universal application to trays of various sizes and structural designs, Iand which when once 1.0 applied to a tray cannot be accidentally disengaged.

It is a further object of the invention to generally promote utility of the devices of the above a character, not only with respect to `adaptability 1b to various types of trays, but also with respect to the comfort afforded to the subject.

Further objects of the invention will appear from the following description in which the preferred embodiment of the invention-has been 20 set forth in detail in conjunction with the accompanying drawing.

Referring to the drawing: Figure 1 is a side elevational View illustrating a deviceincorporating .the present invention, be- D fore application to the edge of a'washing tray.

Fig. 2 is a plan View showing a washing tray to which the device of Fig. 1 has been applied.

. ,.40 Referring 'mst to Fig. 2 or the drawing .there an inclined position, adjusted to the back Yof the neck of the subject, so that water or other liquids applied to the hair areydrained down into the tray. It is the edgey of this forward end portion of the tray to whichj my deviceapplies. l

' Referring now to Fig. V1 my device consists of a body l1, preferably made entirely of resilient l material such 'as soft vulcanized rubber. Extending the entire length of the body there is a slot 12 which serves to receive the edge of the tray. The side of the -body which is to be faced inwardly with respect to the tray is provided with a rib 13 (Fig. 6) in order to minimize splashing 60 back of liquid falling into the tray. An intermediate section of the outer side of the device, that is the side which is intended to contact with the neck of the subject, is provided with a bulge 14 forming a cushion, as will presently be eX- 65 plained.

To afford means for attaching the device -to a tray, the body is provided with end and intermediate tabs 16 and 17. These tabs are preferably likewise made of resilient material such as soft vulcanized rubber, integral with the body of the device. Thus as shown in Figs. 4 and 5, the tabs 16 and 17 are extensions from one side oi the body, whereby when the device is applied to the tray in the manner shown in Figs. 2 and 3, 75 they underlie the forward end portion of the tray. The intermediate tab 17 is shown provided with a pair of grommets or eyelets 18, while the end tabs 16 are shown provided with single eyelets 19.

` It is desirable that the ends .of the device rmly grip the edges of the tray, and that they have sufficient strength to enable a considerable pull being applied to the end tabs 16. For this reason, embedded in the end portions of the device, are the strips 21 of spring metal. (Fig. 4.) These spring strips are hookshaped to embrace the slot 12`and are of suiiicient length to be engaged by the eyelets 19. The rubber forming the body 11 may be thickened somewhat in the 9o neighborhood ofthe spring strips 21, as shown in vFig. 4,`to airord greater strength. Likewise the -are sufficiently flexible as to be readily distortable,

and the wall portion 28 adjacent recess 24 is likewise of reduced dimensions. However' the medial part 29 of wall portion 28 is thickened somewhat, 105 to prevent buckling when bent to the relatively sharp curvature required in placing the device 1 upon a tray. Y

In orderto adequately retain the device upon the edge of the tray, I provide meansupon the unportions of the body.

derside of the tray which exerts retaining pull upon the tabs 16 and 17. Thus as shown in Fig. 3, I provide two retaining cords 3l which have their forward ends tied to eyelets 19 of tabs 16, and which extend through the eyelets 18. The underside of the tray, as is usual practice, is provided with a fitting 32 which serves as a part of the tray supporting means. The' cords 31 are shown engaged about this tting and tied together. It will be noted in Fig. 3 that the length of the device is such that, when applied to the forward end portion of the tray ink a manner shown in Fig. 3, the line of centers of eyelets 19 is spaced forwardly from the line of centersY of eyelets 18. Thus the pull exerted by each of the cords 31 upon the tabs 16 is both inwardly and downwardly (as shown in Fig. 3) and the pull exerted upon each of the eyelets 18 is downwardly and outwardly. Pull exerted in this manner serves most eiiectively to retain the device upon the edge of the tray so that no part thereof can be displaced without first loosening cords 31.

The manner in which my device is used in practice will be evident from the `above description.

-The operator rst engages the device with the edge of the tray, taking care that the tabs 16 and 17 extend upon the underside, and that the edge of the tray is well seated within the longitudinal slot 12. During this operation the device is readily bent to the particular contour which the forward edge of the tray presents. Cords v31 are then slipped through eyelets 18, pulled taut about tting 32, and tied.` Y

As has been previously mentioned it is characteristic of my device that it is universally applicable to all washing trays of this particular character. In the type of tray illustrated no edge beading is employed, but the cords 31 retain the device in itsdesired position, although without such cords the device could be readily displaced. If the tray is provided with arbeaded edge, or with an edge having a distinct depending lip, the device can be applied equally as well, since slot 12 can be readily spread to accommodate different edge constructions, and since frictional engagement is not relied upon of itself to retain the device in proper position. Itis also charac teristic of my device that while it is relatively rugged and of universal application, that portion which is pressed against the subject is soft and yieldable to promote comfort.
