THE INDIA RUBBER WORLD 



[Makcu 1, 1919. 



This often happens through wear of one or the other of the 

 bearing boxes on either the motor or shaft, throwing them out 

 of alinement, which in a short time destroys the journal boxes. 

 It is then necessary lo rebabbilt the journal boxes and realine 

 the motor. This expensive procedure can be obviated by the 

 use of the adjustable anchorage. 



In case the journal boxes wear unevenly the motor can be 

 rotated and easily brought up into position again, whereas with- 

 out the adjustable anchorage the grooves in the base of the 

 motor must be planed out to allow this movement. (Adjustable 

 Anchorage Co., 1502 Ford Building, Detroit, Michigan.)

CALENDER FOR FORMING AND JOINING RUBBER SHEETS. 

 A PLUKALITV of rubber sheets are calendered sufficiently 

 ^ thin to avoid Idisters, and superposed by this machine, form- 

 nii a multiple-sheet of desired thickness for making tire-building 

 strips. In the operation, 

 rubber stock is fed be- 

 tween rolls A and B, and 

 also between B and C, 

 forming banks shown in 

 the illustration. As the 

 rolls rotate in the direc- 

 tion indicated by the ar- 

 rows, the rubber is 

 formed into relatively 

 thin sheets, D and E. 

 The upper sheet D 

 passes over idler roller /•' 

 and under pressure roller 

 (/', where it is united with 

 sheet E and then de- 

 livered from the machine 

 by the conveyor H. A 

 multiple sheet is thus 

 formed that will be free from blisters and devoid of the usual 

 imperfections encountered in calendering thick sheets. Three 

 or more plies may be formed by providing rolls for each addi- 

 tional ply. (John Hanna, assignor to The Fisk Rubber Co., 

 both of Chicopec Falls, Massachusetts. United States patent 

 No. 1,289,744.)

AUTOMATIC LAMP-CORD REEL. 



A very practical device and one that suggests a variety of 



uses in every rubber mill, is the automatic extension reel 



^^■^^^^ for electric lamps. Designed pri- 



^^^t^^^ marily for garages, this reel has 



WSv been installed in factories, inachine 



^^^■1^^^ shops, warehouses, and storerooms 



with satisfactory results. 



The reel is 9 inches in diameter 



by 2 inches wide and carries 25 feet 



of reinforced lamp cord. The head 



is provided with a swivel joint, so 



tliat the lamp may be carried in 



any direction from the reel, and an 



automatic lock checks the cord at 



point. A slow, backward motion of the cord 



causes the lock to hold the cord and the release is 



effected by a slight pull, the cord being automatically 



rewound on the reel. (W. S. Broadhurst, 37-41 Cort- 



landt street. New York City.)
