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. 



In this electric 

 heating faucet the 

 water closes the 

 circuit and sup- 

 plies the resist- 

 ance for heating 



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
