THE INDIA RUBBER WORLD

In operating, the bag or bottle is laid on tbo table, and the table 

 raised or lowered to bring the overflow line of the bag level with 

 the point of contact of the cutters. The bags are then moved 

 over the table similar to cloth passing through a sewing machine. 

 The machine is practically fool proof and will remove 90 per cent 

 of the overflow. Here may be seen the actual work performed 



on the machine. 

 The method 

 used in trim- 

 ming the first 

 bag shows the 

 trimming w a s 

 started at the 

 lower corners 

 (the upper cor- 

 ners shown 

 in cut) on a 

 straight line

neck. On the second bottle, the trimming was started about 

 ^-inch from the neck and the overflow removed up to within 

 J^-inch of the hanger on each side. 



In the first method, with a little practice, from 12 to 15 bottles 

 can be trimmed per minute. The second method takes a little 

 more time, but removes more overflow. With more skill the 

 result should be nearly the same. The third shows the syringe 

 bag before being trimmed, and the fourth shows it after being 

 trimmed. About 98 per cent of the overflow has been removed.—

STANDARD COOLING AND DRYING RACKS. 



The rubber stock cooling rack shown herewith is designed 

 to save time, facilitate handling, economize floor space and 

 increase production. 



It has a cooling capacity of about 400 pounds of tire stock 

 with each loading, or about 800 pounds per hour. The size is 

 30J4 by 30^ by 62;/. inches high, receiving 12 removable trays 

 30 by 30 inches. The trays are 16-gauge perforated steel with 

 corner angles and 2 by 2 inch tray runs and 1 by 1 inch angle 

 well reinforced.

Drying Racks. 



The drying rack is designed for drying jelutong and pontianak 

 stock, etc., and is particularly adapted for use in drying rooms. 

 Its capacity is about 600 pounds of stock when filled. Its size, 

 64 by 30 by inches by 7 feet 11 inches high. The comer angles are 



- by 2 niches, and the frames heavily reinforced to receive 15 

 trays 30 by 60 inches. Tray runs are pitched with the tray stops. 

 The trays are 1 by 1 by ^-inch frame of heavy wire mesh, gal- 

 vanized after weaving. (Chas. W. Carll's Sons, Trenton, N. J.) 



RUBBER THICKNESS GAGE. 



.\ most convenient and accurate dial pocket gage for use in 

 measuring the thickness of cal- 

 endered sheet rubber stock is that 

 shown in the illustration. It is 

 equipped with jaws which have 

 large flat surfaces designed for 

 gaging paper or rubber. It is 

 graduated to read by 0.001 of an 

 inch. The diameter of the dial is 

 IH inches, and the spindle has a 

 travel of 0.3-inch. (B. C. Ames 

 Co.. Waltham, Massachusetts.)

INNER TUBE PATCH BUFFERS. 



These devices are recommended for quickly and thoroughly 

 removing chalk, bloom and grease from inner tubes preparatory 

 to the application of rubber patches. 



These buffers are made in two designs as shown in the illus- 

 trations, the Cordell is more ef- 

 fective but the Nugent occupies 

 less space and therefore may be

preferred. The principle is the same in both — small sharp- 

 toothed projections that will clean the surface and not cut the 

 tube deeply. (Cordell Manufacturing Co., 709 Pine St., St. 

 Louis, Missouri.) 



COAL HANDLING CONVEYORS. 



The scoop conveyor shown in the illustration provides a con- 

 venient, eflicient and flexible arrangement for handling coal or 

 similar material. For example: five machines may be used to 

 unload coal from hopper bottom cars direct to 

 a storage pile. Each is equipped with its own 

 electric motor and can be operated singly if 

 desired. The first machine is practically self- 

 feeding from the hopper doors of the 

 car, and the other four may be swung 

 around at any angle to cover a wide 

 storage area. 



These machines can also be used 

 to convey the coal direct from stor- 

 age pile into boiler room, or when 

 desired, one machine can be used to 

 load an electric storage 

 battery truck to convey the 

 coal directly into the boiler 

 room. 



The advantage of using 

 the scoop conveyor to un- 

 load hopper bottom cars 

 is that no track hopper or 

 pit is necessary, making it 

 possible to unload cars at 

 anv point along the track. (Portable Machinery Co., Inc., Passaic, 

 New Jersey.)
