NEW GOODS AND SPECIALTIES IN RUBBER. 



THE G & 1 TIKE STRAPS 

 /-T-^HREE excellent emergency straps for temporarily re 

 I pairing bursted or punctured tires are put out by 



-*~ the G & J Tire Co. The first of these is the Repair 

 Strap shown in the illustration . It is made of heavy 

 canvas, 2 '4 inches wide, and covered with a coating of rub- 

 ber. One end of 

 the strap is buck- 

 led to a spoke 

 iiid the remainder 

 tightly wrapped 

 around the tire, 

 making seven to 

 eleven turns ac- 

 cording to the size 

 of the tire, and the end secureh' buckled to another spoke. 

 The outside tire sleeve is another good device. It is made 

 in one piece, of thicker canvas and rubber than in the repair 

 strap. It has eyelets and lacings and is made in several 

 sizes to fit tires of various types. The third of the series is 

 called the G & J inside tire sleeve. This is a belt of soft 

 rubber. Its function is to mend a bad rent in the tire until 

 the car can be run to a shop where permanent repairs can be 

 made. It .serves its purpose better when used in connection 

 with one of the devices above described. [G & J Tire Co., 

 Indianapolis. Indiana. | 



CLOTH LINED WATER BOTTLE. 

 Tiiic ■ ' Wearever " is the very suggestive name given to 

 the cloth lined water bottle that is high in popular favor at 

 the present time. It may be had with or without the 

 " holdfast " attachments and with smooth or ribbed surface. 

 It is light and at the same time strong, a combination that 

 is as desirable as it is rare. The colors in which it comes 

 are maroon, non-blooming and white. Syringes with tubing 

 to matoh and combination water bottle and fountain syringe 

 with rapid How attachment are also specialties in this line 

 of goods. [The Faultless Rubber Co., .\kron, Ohio.] 



AN INGENIOUS AIR PUMP. 

 .•V UKScuiPTioN has sometime appeared in this department 

 of the l{vans vacuum cap, designed for the stimulation of 



the circulation of the 

 blood under the scalp by 

 means of creating a vac- 

 uum under an airtight 

 fitting helmet. An in- 

 genious air pump is used 

 in connection with form 

 ing the vacuum, the same 

 being attached to the chair 

 in a position convenient 

 for its working by the 

 person taking the treat- 

 m e n t , and we have 

 thought it worth while to 

 present an illustration of 

 this feature, as a matter 

 of interest, perhaps, to 



others requiring a simple and convenient air pump. [Evans 

 Vacuum Cap Co., FuUerton building, St. Louis.] 



RUBBER STAMPS IN DRAFTING WORK. 

 With 11k- improvements constantly being made in the 

 construction of rubber stamps, they are all the while finding 

 new uses. One which has not been referred to before in 

 these pages relates to their application to work in drafting 

 rooms. It often happens that many copies of a single detail 

 in mechanical drawings, or in architectural work, are re- 

 (juired, and the time and expense involved in making dupli- 

 cates by hand are avoided by having a rubber stamp made 



RUBBER STAMP FOR MECHANICAL DRAWING. 



of the feature which is to be repeated a number of times. It 

 may be that part of a drawing will need to be repeated many 

 times, while additional details will have to be made sepa- 

 rately in each case. When this occurs, it may prove eco- 

 nomical to have the part which is to be often repeated made 

 in the form of a rubber stamp. vSuch stamps have been 

 made extensively for mechanical concerns and for the I'nited 

 States navy by T. S. Buck Manufacturing Co., New York. 

 A GERMAN RUBBER TIRE TREAD. 

 Oi- the many tire treads that are designed to prevent 

 skidding, one that is illustrated here deserves special men- 

 tion because of its 

 undeniable merit, 

 and, again, be- 

 cause it is made 

 of rubber and is 

 really a part of 

 the tire itself. 

 The Calnion tread 

 is rigid, yet pli- 

 able ; resilient, 

 yet durable. In 

 design it is neat 

 and sightly. As 

 a preventive of 

 piinctures it is 

 claimed that this 

 tread is one of the most efficacious in the market. It may 

 be made as a part of the tire, or as a separate band and vul- 

 canized on the outside of any rubber tire, [.^sbest- und Gum-
