POWER SAW FOR CUTTING SOLID TIRE BASES. 



A novel application of the power hack-saw principle is shown 

 by the accompanying illustration of a machine especially designed 

 for cutting steel rims of solid tires. It is intended for use in 

 service stations where worn-out tires are removed and new ones 

 substituted on the wheel. 



Solid truck tires are made on steel bases and forced on the 

 wheel-rim by hydraulic pressure. In time, the wheel-rim and tire- 

 base become firmly united and it is necessary to cut the steel 

 base in order to remove the tire. 



The wheel is clamped to a frame that is raised or lowered by 

 worm-gearings operated by hand-power. The machine cuts on 

 the draw stroke and the saw-frame is lifted on the return stroke 

 by a compression oil lift-pump. .\ gage is provided to stop the 



SOAPSTONE-BRUSH. 

 By the use of this hand device, powdered soapstone may be 

 applied to the surface of rubber stock without creating clouds 

 of dust in the operation. 

 It comprises a con- 

 tainer body, the bottom 

 of which supports the 

 bristles of the brush, and 

 the top of which is a 

 flexible diaphragm. The 

 soapstone is delivered to 

 the brush portion of the 

 device by pneumatic 

 pressure which is set up 

 within the device by the 

 hand of the operator 

 grasping the brush- 

 handle. 

 Connected to the diaphragm are means for breaking up any 

 lumps of soapstone caked within the container body, as the 

 diaphragm top is reciprocated by the user. The soapstone is 

 deposited in the center of the brush and, by the movements of 

 the operator's arm, is distributed over the surface to be dusted.

Solid-Tire-Base Cutting Saw. 



cutting when the steel base has been severed. The saw-frame is 

 adjustable for blades from 12 to 24 inches and will cut bases up 

 to 16 inches wide. The machine may be driven by belt power or 

 direct-connected motor. (W. Robertson Machine & Foundry Co.,

MACHINERY PATENTS. 



APPLYING BALATA TO FABRIC WITHOUT SOLVENT. 



FABRICS may be simultaneously coated with balata on both 

 sides by this method, and without the use of solvents. The 

 accompanying drawing is intended to illustrate only the coating 

 device, which in this instance conveniently comprises the top roll 

 of a three-roll calender especially adapted for this purpose. 



The balata stock is warmed up 

 in the usual manner and banked 

 above and below the fabric A as it 

 passes between rolls B and C, that 

 are excessively heated by steam. 

 The impregnated fabric passes 

 upwardly between the middle and 

 upper, or cooling, roll D. and 

 around the latter to the wind-up 

 roller. 



The cooling roll D is chambered 

 for internal water cooling, while 

 water jets sprayed from pipe E, 

 arranged parallel with the roll, 

 effectively cool the exterior sur- 

 face of the cylinder. Trough F serves to carry oflf the water, 

 and a rubber scraper attached to the inner edge of the trough 

 removes the water from the roll and deflects it into the trough.
