is then further compressed and passed into the condenser 8C. 

 The solvent condensed out in these three coolers is drawn off 

 by gravity to a separation tank 14 where it is separated from any 

 accumulated water, and the residual inert gas reduced to ap- 

 proximately atmospheric pressure by 13 is passed back into the 

 impregnator housing. The system is thus essentially a complete 

 cycle, except as additional flue gas is added to replace losses 

 that must necessarily occur. (Lewis Recovery Corporation,

AKRON-WILLIAMS TIRE REPAIR NOVELTIES. 



Tire repairing as a business will attain a greater development 

 in direct proportion to the energy exercised in building better 

 repairs. That progress is constantly being made in the develop- 

 ment of tire repair equipment, to the convenience and economy of 

 repairmen, is shown in the accompanying illustration. On the 

 left is an inverted tube vulcanizer, unique in its adaptation of a 

 principle giving greater efficiency and ease of manipulation. The 

 tube hangs down away from the heat during the cure. The

pressure bars are controlled by foot-pedals enabling the repair- 

 man to have both hands free to adjust tube on the hot plate. A 

 feature of construction, when this outfit is built to use gasoline 

 as fuel, permits it to be pushed about the garage or repair shop 

 floor at the convenience of the operator. 



The special one-and-one-half horse-power boiler or generator 

 shown in the illustration on the right is of vertical tubular type 

 and of steel construction throughout. It is readily convertible 

 from gas or gasoline burning to coal or coke burning with the 

 addition of a small section which fits to the bottom of the boiler 

 unit. This boiler has a very low w^ater line, permitting a gravity 

 return from the vulcanizing units without necessitating the plac- 

 ing of the boiler in the basement or on the next lower floor.

CHAMPION TIRE BUILDING STANDS. 



Spinning tlu- tire v, ith one liand and using the various tools 

 with the other is eliminated in this machine as the operator 

 has both hands free and can revolve the tire either forward or 



These stands are made in three dififerent types. The one 

 shown in the illustration is the base with four projecting arms, 

 enablins; four men lo work at the stand. The second is the

l.iase witli two arms parallel with each other, enabling two men 

 lo work at the same stand; and the third is the single stand 

 for one man. 



The four-man base can be sold with one arm and other arms 

 can always be added as the manufacturer requires them. There 

 are ball bearings on both the main drive shafts, thereby making 

 the machines noiseless and easy to run. ( The Braendel Engi-

MACHINE FOR COATING INSIDE OF CASINGS. 



The problem of coating the inside surface of casings with a 

 preparation so that the casing and tube will not adhere, has 

 been solved by the machine here pictured. After a long period 

 of satisfactory service, and after basic patents have been granted, 

 it is now being brought to the attention of the trade. 



The outstanding features of the machine are speed of opera- 

 tion and simplicity. From six to ten tires per minute are lined 

 evenly from bead to bead, and without wasting the liquid, there- 

 by saving at least two-thirds of it as compared with the present 

 hand-swabbing method. Three tires are rotated at a time in a 

 vertical position on drums driven by a small electric motor. 

 The beads of the center tire are held apart by a dished wheel 

 having an ( perating handle. This permits the spraying device,
