Fig. 2 is a where m the line of the arc K (see Fi 2) and side or edge elevation of the mechanism lllsu anywhere in the line of the are L. (See shown in Flg. I, the hlowpipe being moved Fig. 3.)

This universal invention. Fig. 5 is a side or edge elevation of the devices shown in Fig. A. Fig. 6 illustrutes a single feature of my invention in side edge view. Fig. 7 is a front elevation of the mechanism shown in Fig. 6.

A indicates a tube for conveyin a fluid or fluids forward to the nozzle B. 'l iese lluids may be impelled forward through the tube A by any suitable means. Some of the wall own menu for this purpose are a rubber bulb, such as W, or a pump with or without a valve, all of whose operations are well understood device of more limited scope, but e1:- ceedingiy useful within limits, is the one shown in Fig. 5 where the aim between the nozzle B and t section is shown at C. This joint is located behind the mirror. -It enables the front end of the nozzk to be turned around anywhere in the circular-dine Y, and thus adapts the nozzle to be used at many convenient points in connection with the mirror. Where the device is to be used osesprayer, the delivery-tube will be divided into two parts, one for conveying the it: end the other for conveying a liquid. the mode.
