New Machines and Appliances. 



THE "AKRON" FRICTION CLUTCH. 



WHILE the principle of this clutch is not new, it is of in- 

 terest to the rubber trade, due to the refinements of de- 

 sign and construction necessary to meet the demands of 

 a reliable power-transmitting devce. Its simplicity and durability 

 make it of special advantage for rubber machinery, and particu- 

 larly so when used on tire-building machines. 



There is only one point to adjust, and the adjusting screw is 

 always accessible. The clutch can be quickly adjusted to slip, 

 when a given load is exceeded, thereby avoiding wrecking other 



Frictio>" Clutch 



parts of the power transmission. It takes hold slowly, reduces 

 shock, and consequently lengthens the life of the machinery. The 

 pulley is not a part of the clutch and is easily interchangeable. 

 The friction parts are all of metal and run in oil ; consequently, 

 the wear on these parts is reduced to a minimum. As all work- 

 ing parts are enclosed in a metal case, and there are no toggle 

 arms, levers, or other traps to fan the air and endanger oper- 

 atives, it can be run at high speed vi^ith perfect safety. Made 

 in all sizes from %-h. p. at 100 r. p. m., and up. (The Williams 

 Foundry & Machine Co., Akron, Ohio.) 



THE PFAUDLER UTILITY POT. 



For small-scale manufacture and laboratory practice, rubber 



chemists will be interested 



I the acid-resisting glass-enameled 

 utility pot shown in the illustra- 

 tion. The vessel is made with an 

 outer jacket and its inside dimen- 

 sions are: diameter 18 inches; 

 depth 25 inches ; capacity 26 gal- 

 lons. It is convenient to handle, 

 easily moved, may be raised, or 

 lowered in temperature, and is very 

 effective in resisting acids or 

 alkalies. (The Pfaudler Co., 

 Rochester, New York.)

that are rusted, corroded, or 

 otherwise stuck fast may be easily 

 removed after applying a few 

 drops of the former. The latter removes tar, asphalt, grease and 

 stains from automobile bodies, mud-guards, and tires. (Polygon 

 Products Co., 141 Milk street, Boston, Massachusetts.)

STEEL TABLES AND DRY COMPOUND BINS. 



Tlic progressive rubber manufacturer will be interested in the 

 line of steel factory equipment here illustrated. It comprises 

 tables, compound bins, and other factory furniture. The first 

 cost of such equipment 

 is practically the final 

 cost. There is little de 

 preciation and low insui- 

 ance rate. 



The drjf compound 

 bins, built in double com 

 partment units, meet in 

 every way the most 

 stringent requirements 

 for dry compound stoi- 

 age. Each compartment 

 has its own cover foi 

 the protection of the 

 contents by excluding 

 accidental impurities. 



The all-steel tables are 

 perfectly adapted for holding warm or soft batches for cooling 

 or keeping free from damage bj' contact with splinters of wood. 



Cooling T.able. 



which are an annoying cause of trouble wherever wooden equip- 

 ment is used in a rubber mill. (Charles W. Carll's Sons, 

 Trenton, New Jersey.) 



KREMER TIRE-BUILDING MACHINE. 



This machine is especially designed with the view of repro- 

 ducing all the essential features employed in producing a hand- 

 made tire in a machine-made product, advantages that will be 



readily appre- 

 ciated by any 

 one familiar 

 with the art 

 of machine tire 

 construction. 



A fabric ten- 

 sion device is 

 employed that

all the different plies of fabric alike, the desired percentage of 

 stretch being determined at will by the operator. 



The core-supporting arm rotates on its axis, whereby the 

 core can be made to assume either a vertical or a horizontal 

 position without affecting the rotation of the core. This feature 

 greatly facilitates the setting of the beads, as with his arrange- 

 ment the bead-setting rings are entirely eliminated. 



In this machine a single spinning head is employed which 

 stitches down the fabric in a manner similar to that of the hand-
