THE INDIA RUBBER V/ORLD 



[January i, 1907. 



is had. When a space shows between the ends of the ring, 

 it is loose and as soon as the ring is taken off — nothing holds 

 it now — the deflated tire maj' be removed for repair or re- 

 placement. Conversely, after the tire and rim are put back, 

 the turnbuckle is screwed np, and the tire is readj- for infla- 

 tion. [The Hartford Works Co., Hartford Connecticut.] 



VENTILATED RUBBER BOOTS. 

 Ii' the patentee of the Ventilated Rubber Hoot finds the 

 theory that he has worked out as practical as it seems, the 

 chief objection to the wearing of rubber boots will have been 

 removed. The ventilating openings in the foot lead to chan- 

 nels which are conducted upward. .\ series of pockets is 

 produced in the foot .section by the pressing out of the 

 waterproof material and the lining into which the heated 

 air escapes through small perforations. In hi]) boots some 

 of the chambers lead to the top of the hip section and others 

 to the top of the knee section when the hip is folded down 

 on the knee section, in this way providing for a comjilete 

 ventilation under all conditions of use. This scheme of 

 ventilation not only serves the u.ses of extreme comfort, but 

 strengthens the shoe. The patentee is Peter M. MacKaskie 

 of Zonopah, Nevada. 



THE "ideal" solid HEEL. 

 N.-vn,s for attaching the heel of a rubber shoe to the insole 

 are apt to make trouble for the wearer, in that they are liable 

 to pierce into the heel of the fool as the boot heel wears 

 down. With the " Ideal " heel this is not possible for the 

 five stout nails that are in each heel are solidly clinched on 

 to the insole. The method employed in doing this makes 

 any discomfort impossible. This method, too, prevents 



damage on boat decks or finished flooring, as some project- 

 ing nail heads have a habit of doing. Another feature in 

 favor of the Ideal heel is that of its having an all-rubber sur- 

 face, the nails being embedded, which makes walking easier 

 and noiseless. These are especially desirable in the lumber- 

 men's goods, although the new device is used on all solid 

 heel rubber goods made by the company e.xploiting it. [The

LEATHER TOP LUMBERMAN'S SHOE. 



The advantage of a leather top lumberman's shoe in some 

 situations will readily suggest themselves. Such an article 

 is made by The IMerchants Rubber Co., Limited (Berlin, 

 Ontario). The leather is of fine quality, soft and pliable, 

 block pebbled grain. The upper of the bottom is made with 

 a snag resisting interlining of long fiber twisted cotton, thor- 

 oughly impregnated with rubber. The sole is made of tough 

 rubber, thickened at the ball, having the corrugated part ex. 

 tend' to and meet the heel, thus giving extra shank protec- 

 tion. The leather top is set inside of the rubber bottom and 

 sewn to it with three rows of heavy silk hardash, having the 

 threads countersunk in the channels of the rubber beading 

 on the upper. By sewing on the inside, the leather does not 



come in contact with rubber,' and any oil that might be in- 

 jurious will be absorbed by the heavy fusion cotton lining. 



GOODRICH CLINCHER MOTOR CYCLE TIRE. 

 One of the chief requisites of motor cycling is durability 

 of tires. This means, of course, a tire that is capable of 

 w i t hstanding 

 good hard rid- 

 ing and plenty 

 ofit. Strength 

 is the first con- 

 sideration i n 

 this connec- 

 tion, but by no 

 means the 

 last. It is 

 quite as neces- 

 sary, a t an)- 



event for the comfort of llie rider, that the tire be reasonably 

 soft and pliable. These qualities are combined in the Good- 

 rich Clincher Motor Tire to a very unusual degree, and af- 

 ford the rider a freedom from responsibilitj' arising from 

 care or thought of possible inconvenience or something 

 worse, liable to occur from accidents. While no tire is ac- 

 cident proof some are much farther removed from the prob- 

 ability of disaster and its accompanying peril and — inconven- 

 ience — than others, from the possibilitj'. and too great care 

 cannot be given to their selection. The number on the mar- 

 ket to make a choice from are almost legion and each one is 

 said to be the best, but the palm must be awarded to those 

 having the greatest number of good points. [The B. F.

COMBINATION ROD PACKING. 

 The packing here illustrated is made of alternate spirals 

 of square duck and braided flax with a cushion backing of 

 thick rubber, and 

 this in turn is 

 protected by a 

 wrapper of duck. 

 It will be seen 

 that this affords 

 a spring)', n o n 

 hardening, an d 

 durable packing. 

 It may be used 

 with equally good 

 results for steam 

 or water and for 

 hydraulic pumps, 

 steam hammers, 

 and where repeat- 

 ed shocks must 

 be endured it es- 

 pecially recom- 

 mends itself. It is made in sets to fit all sizes of rods and 

 stuffing boxes. The confidence of the manufacturers in this 

 product is indicated by the fact that thej- offer it to the 

 trade at a price above most other packings in the market.

A RECENT sale in London included a very nice lot of Cas- 

 iilloa rubber from Java at 4^. zd. [=$i.oi>f] per pound.
