This Electric Heating Faucet Has No A Space-Saving Display Fixture Which

��Switch or Coils

��AN electric water-heating faucet, just

��Graphite rod

��Nickel cover

��placed on the market in California, differs from other devices of this kind in having neither electric switch nor coils, the water itself serving to close the circuit and to supply the resistance for heating. The device is so made that cold, wacm or hot water, depend- ing on the position of the handle, is supplied instantly.

The heating element, housed in the cylindrical casing that forms the top of the device, consists of an upright hollow car- bon cylinder enclosing a spacs in which is a graphite rod. These parts are insulated from the remainder of the device, and each is connected by an in- sulated wire with one pole of an ordinary lighting circuit. When the handle is turned to the "cold" position, the water flows through a by-pass without entering the heating element. When it is turned to the "warm" position, the by-pass is closed and the water passes upward between the cylinder and post, overflows at the top and passes downward in the space between the cylinder and cover. The cir- cuit is closed by the water, thus doing away with the neces- sity for a switch, since no current can flow unless the heat- ing element of the faucet is filled with water.

When hot water is wanted, the handle is turned to such a position that only a small flow of water is admitted — just enough to allow it to be thoroughly heated before it reaches the outlet.

��Also Saves Clerk Hire

THE display fixture shown in the photo- graph below will prove a money-saver as well as a convenience to the shop-keeper. It consists of a framework having a number of inclined drawers which may be drawn forward to hori- zontal position or sloped back- ward and up, so as to dis- play every article to the passerby. The drawers may be provided with hinged glass covers or left open as desired. When covered, they are opened by simply raising and sliding forward the front part of the drawer. Customers may examine at leisure all the articles in the various drawers without special attention from the clerk, so that one clerk may attend to several customers at a time. As the framework stands on a twenty - seven - inch base, two cases can be placed back to back so that articles can be dis- played to customers in two aisles at the same time. One clerk can serve two cases. In the drawers underneath the frame, heavier articles or surplus supplies are kept. In this way every available inch of floor space can be utilized. Moreover, the clerk, having his stock plainly marked as to prices and always before him becomes thoroughly familiar with it in little time.

���With prices plainly marked, the articles in this compact display case practically sell themselves. Surplus stock is kept in the drawers below
