BRUSHERS FOR CALENDER LINERS. 



COTTON BRUSHER AND CALENDER-ROLLING 



MACHINE. 



A MACIIINI'; adapted to use in every riil)ber factory is 

 -^^*- the clotli Ijrusher .shown in the first of the ilhistr;i 

 tions herewith. Its use will be appreciated by every caleii 

 lit! man who has occasion to clean the liner sheets of lint. 



talc, and the like. 

 This cloth brush- 

 ing machine is ar- 

 ranged with emery 

 rolls and beaters in 

 front, and with cord 

 rolls and a stiff 

 brush on top, so 

 that each side of the 

 cloth can be cleaned 

 b\- going through 

 once. Other arrangements of brushes can be made, if 

 desired. The beaters have steel blades with sharp edges 

 which run against the cloth and knock ofl' bits of adhering 

 material which are not easily removed in any other way. 

 The machine is entirely covered on top and around the 

 emer3' rolls and beaters (the covers being removed in order 

 to give a view of the machine), and has an e.xhaiist fan 

 underneath to carrj- off the dust. The cut shows in con- 

 nection with the brusher a calender rolling machine, witli 

 steam vapor cylinder. 



The second cut illustrates the Heath patent vertical 

 brusher. which form is preferred in some mills. After 



passing over 

 tension and 

 spreader bars 

 in front, the 

 cloth enters at 

 the bottom of 

 the mach i n e 

 .iiid passes 

 straight up to 

 the top, being 

 cleaned on 

 both sides b3'

At the bottom of the machine is a hopper connected by a 

 pipe to an exhauster for taking off the dust and lint. This 

 cut also shows the brushing machine running in connection 

 with a calender rolling machine. [Curtis & Marble Machine

BRICKLAYERS' TAPE. 



'T^O THE Editor of Thic Indi.\ Rubbkk World : lu the 

 ■*- November issue of your journal appeared an article in 

 which I was much interested, viz. : " Automatic Tape Cut- 

 -ting Machine. " But I found in enumerating the articles 

 which it has been designed to cut, that of India-rubber tape 

 for bricklayers was omitted. This is quite an important 

 factor in the output of the tape cutting machines, and is used 

 by brickla5ers for winding their fingers while at work. The 

 tape so used is known as mud fingers. An item worthy of 

 note in this connection is that 500 tons of bricklayers' tape 

 will be used by ma.sons in San Francisco during the rebuild- 

 ing of that city. K. .\. SANl-'DRU. 



MACHINE FOR MOLDING FOOTWEAR PARTS. 



''T'^lll-; illustratiun relates to a machine for forming the 

 ^ parts of rubber footwear. It involves the combina- 

 tion, with an endless table, of (1) means for supporting the 

 table, (2)nieans 

 where b y the 

 table is moved, 



(3) a series of 

 molds formed 

 in tlie surface 

 of the table, 



(4) a combined 

 feed and press- 

 er roll mount- 

 ed above and 

 adjacent to the 

 table in verti- 

 cal line with 

 thu support- 

 ing means, (5) 

 and means for 

 feeding rubber 

 stock in a semi 

 fluid state to ', j 

 the space be- \^ ^/ 

 tween the roll 



above the table and the surface of the table, such roU being 

 adapted to feed the stock under pressure from the said space 

 into the mold. The inventor is Mr. Charles L. Higgins, of 

 Montreal, to whom United States patent No. 835.522 has 

 been granted. 



MOLD FOR RUBBER TIRES. 



A 



NEW invention 

 is illustrated i 



in the shape of a mold for rubber tires 

 n the accompanying sectional drawing. 

 It is a vulcanizing mold having 

 in combination body portions 

 ^';j^ with recesses in their inner or 

 ^ adjacent faces, and a series of 

 ^ removable sections with mat 

 § rices, the intermediate sections 

 ^ being constructed to interlock 

 ^ with adjacent sections, and the 



•^^ cesses in the body portion. 

 The inventor is Mr. Wilmer 

 Dunbar, a widely known rub- 

 ber superintendent and vice pre- 

 sident of the Penns3lvania Rub- 

 ber Co. to whom United States 

 patent No. 834,608 has been 

 granted. 



sections at the ends of the 

 series with the walls of the re- 



-VccoKDiNG to theirnited States census of 1905 there were 

 957,409 family and pleasure carriages manufactured in that 

 j-ear, and 645,755 farm and business wagons. Not all these 

 were rubber tired, but the proportion so equipped is alone 

 enough to call for a very great amount of rubber.
