NEW GOODS AND SPECIALTIES IN RUBBER. 



"monarch" massage bath spray. 



THE " Monarch " massage bath spray is so constructed 

 that it can be used as a brush and spray at the same 

 time and attached to any faucet. The brush consists 

 of soft rubber bristles. At the base of each bristle is a 

 small hole which allows the water to flow past them, making a 

 spray, the force of which can be regulated by the pressure of 

 water. By using this spray, one may begin taking a bath just 

 as soon as the water is turned on. It is unnecessary to have 



any water in the tub, and 

 thereby a great deal of 

 time is saved. This is es- 

 sentially a sanitary bath 

 spray, owing to the fact 

 that the brush and spray 

 can be easily detached 

 from the metal back, thor- 

 oughly cleaned, and re- 

 placed. It is excellent to 

 use for shampooing, as it 

 massages the head and 

 rinses the hair. The rubber brush being of a soft velvety na- 

 ture, does not scratch the skin, as is the case with bristle 

 brushes, but is more cleansing. It merely causes the blood to 

 circulate freely, creates a glow, and puts the pores of the body 

 in a natural and healthy condition. The spray is supplied with 

 connections for single or double faucets. United States patent 

 No. 757,791, issued to V. C. Vant Woud. [The Vant Woud

A novel solid rubber tire. 



A vehicle tire protected by United States patent No. 763.- 

 909, issued June 28, 1904, to Alvaro S. Krotz, Springfield, Ohio, 



consists of a continuous 

 band of rubber, prefer- 

 ably held in the channel 

 by longitudinal retain- 

 ing wires, the novel feat- 

 ure of the invention be- 

 ing a series of cavities 

 or pockets cut in the 

 tread, all of which is 

 sufficiently illustrated in 

 the drawing herewith. 

 The inventor finds that 

 tires formed of a contin- 

 uous tread have a ten- 

 dency when loaded to crowd over the sides of the retaining 

 channel, and, when the wheel is under action, to creep in the 

 channel ; or else the longitudinal movement of the rubber 

 will be transmitted to the base, loosening it, or tending to sep- 

 arate the base from the tread. The object of the pockets, 

 in this invention, is to provide places into which the rubber 

 can flow, and to break up the longitudinal movement, so as 

 to keep it away from the base and its fastenings and retaining 

 channel. The inventor says: "It has been found in practice 

 that in well known sectional tires the sections individually are 

 not able to withstand the extreme torsional strains. With 

 my improved tire there are no sections as such, but the parts 

 are interconnected, thus adding to their resisting power with- 

 out destroying their individuality and resiliency, and provid- 



ing an even tread surface." While the form of cavity shown 

 in the illustration is V shaped, or sharp at their base, they may 

 also be formed in U shape ; they may also be arranged opposite 

 each other, instead of alternating. Besides, the invention may 

 be adapted to rubber tires of other sections than that shown 

 herewith, and formed to be adapted to other channels or other 

 means of retaining the rubber to its seat. 



"tred-air" heels and heel cushions. 

 The first of the illustrations herewith relates to a new rubber 

 heel, sold under the name " Tred-Air," which possesses two 

 distinctly novel features — a treading 

 surface of non slipping fabric, and an 

 air cell construction for the body of 

 the heel, which renders the whole 

 lighter in weight and more springy 

 than solid rubber heels. These heels 

 are referred to as possessing the same 

 advantage over th se previously in use 

 that the pneumatic tire possesses over 

 solid tires, with respect to resiliency, 

 though the cost is not greater than 

 the old style heels.= — A second nov- 

 elty introduced by the same firm is 

 ' Tred-Air " heel cushion, to be worn inside the shoe. This 

 also involves the air cell principle of construction. They are 

 commended to those per- 

 sons, among others, who 

 object to the appearance 

 of rubber heels on shoes. 

 Other advantages of the 

 heel cushion are that it can 1 

 be adjusted to the shoe in 

 an instant ; that it will 

 wear indefinitely, and can 

 be changed from one shoe to another; and that it increases 

 the height of the wearer and gives an arched instep. This 

 cushion has been recommended by physicians, chiropodists, 

 and other specialists. [Tredair Rubber Co., Boston, Mass.] 



the "autophone" horn. 



One of the latest novelties for the motorist is a horn ot 

 French production, described as an " Autophone." A feature 

 of its construction is the double turn in the tube, or metal part 

 of the horn between the reed and the opening, as shown in the 

 illustration. There is thus produced a much greater volume 

 of sound than the horn of a single turn of pipe. This is 

 not at all objectionable, however, as is thus explained:
