A CLEAR-VOICE TELEPHONE ATTACHMENT 



A new telephone mouth-piece of hard rubber allows the voice 

 to sound natural, it is claimed, and prevents the speaker being 

 overheard. E.\ces« vibration is provided an 

 outlet through small holes at regular inter- 

 vals drilled through from the end next the 

 telephone lo the shoulder just above the screw- 

 thread, as indicated in the picture. A crys- 

 tal bead hung on a monel metal bar and shown 

 here in the cut-out, breaks up the sound waves 

 and also prevents foreign articles such as pen- 

 cils from being poked into the mouth-piece. 

 A shoulder for a muffler plate is also provided. — The Evolu- 

 tion Phone Co., Inc., 48 Greenwich avenue, New York City. 



RUBBER DRESS ACCESSORIES 



Of the two novelties shown here, the dress shields, which 

 have a connecting strap of shirred fabric across the back, de-

"Shiri.astic" Dress Suieid 



rive their name, "Shirlastic," from this 

 feature, which is patented. .\ double 

 strip of muslin attached to the back 

 edges of the shields forms a casmg for 

 the insertion of narrow elastic webbing 

 or cords. These shir the strip when not under tension and pro- 

 vide means to prevent the shields from slipping away from posi- 

 tion. There are also shoulder straps of elastic and similar ones 

 over the arms, while shaped sections of net, fastened by tying, 

 form a brassiere effect at the front. 



"Shirlastic" ribbon, a shirred ribbon-covered elastic, is also 

 to be marketed by the same manufacturer. It is to be used for 

 garters, baby carriage straps, camisole trimmings, boudoir caps, 

 etc., and may be had in different widths, in both plain and 

 fancy patterns. 



The tasseled beach bag, made of pure rubber, has an attrac-' 

 tive design in colors printed on the outside. It is of good shape 

 and roomy, iii graceful pattern, and the opening is easily 



gathered up with draw- 

 strings. — 1. B K leinert

A STEP TOWARD SAFETY 



Rubber heels have come in- 

 to such general use that the 

 question is not, "Do you wear 

 rubber heels ?" but rather, 

 "Do you prefer rubber half- 

 heels or whole-heels?'' Many 

 persons use whole-heels on 

 outing shoes and half-heels on 

 more dressy footwear. Made 

 for all tastes is the "Velvet 

 Xevcrslip Friction Plug" 

 rubber heel, which comes in many sizes, both whole style and half 

 style, with or without the inserted friction plug, said to prevent 

 slipping. These heels show very careful workmanship, both in 



"Velvet" Phig Heel 



molding and linishing. and have not the objectionable clumsy 

 appearance of low-grade heels. — Frank W. Whitcher Co., Bos- 

 •on, Massachusetts. 



A TIME AND TEMPER SAVER 



A handy tool commendable to the motorist for its simple 

 working principle is the "Easy-Way" wrench, which has two 



Fitil. loo.en Ihc Nul Thi, W.y Thtn Spin n 0(( ThU W^

 liandles for gripping and starting the nut and a central one to 

 continue the twirling motion until the nut comes olif. Handles 

 are of highest grade malleable steel and the entire tool is hand- 

 somely linished in black rubber enamel. \ later development is 

 the "Easy-Way Tri-Socket" wrench, to tit practically all makes 

 of demountable rims. It combines in one tool sockets for 5^-, 

 11/16- and f^-inch nuts. The handle can be conveniently ad-

 justed to use whichever socket is required. — F. K. Lawrence

THE "NATIONAL AIRLESS" TIRE 



A tire having the general appearance of the ordinary pneu- 

 matic, yet differing essentially from it inasmuch as it does not 

 require inflation, is the "National Airless," being manufactured by 

 a company in 

 Los Angeles. 

 The tire uses 

 neither inner 

 tube nor com- 

 pressed air, but 

 contains instead 

 a bridgework of 

 rubber piers and 

 ribs inside a 

 casing and vul- 

 canized into one 

 piece, the whole 

 designed to give 

 resilience with- 

 out the risks of 

 punctures or 



blow-outs. It is the intention of the company, which has already 

 a large number of these tires in operation in the Southwest, to 

 set up a large factory soon in the south end of the city. Applica- 

 tion has been made for a patent. — National Airless Tire Co., 

 North Main street, Los Angeles, California.
