pinion E operated by a hand wheel F is engaged with a segment 

 G, so that when the wheel is turned the lever // is thrown to the 

 left to force the clutch together. 



In case of emergency, the cord or bar suspended over any one 

 of the machines is pulled, releasing the weight /. As this weight

RECENT MACHINERY PATENTS. 



A SIDE from the machines described above, there are a num- 

 *■ her of other interesting devices recently patented in this 

 country and abroad, but which lack of space prohibits illustrating. 

 These are briefly described below. 



U. S. Patent No. 1,099,535, June 9, 1914. Granted to A. C. Bol- 

 ton, and assigned to the Gutta Percha & Rubber Manufacturing 

 Co., of New York. This is a machine for wrapping hose with 

 fabric preparatory for vulcanizing. Instead of applying the fabric 

 in a spiral winding, it first wraps a strip of fabric longitu- 

 dinally around the hose and then applies a spiral winding outside 

 of this. This eliminates the spiral marks left by the edges of the 

 fabric. The hose mandrel is omitted and the hose inflated with 

 air while being wrapped. The machine may also be used for un- 

 wrapping the fabric after vulcanizing. 



U. S. Patent No. 1,099,763, June 9, 1914. Granted to Russell 

 Parker of Parker, Stearns & Co., Brooklyn, New York. In the 

 specifications of this patent are described an apparatus and a 

 process for making rubber covered belts, such as are worn by 

 women for holding dow-n the shirtwaist and supporting the skirt. 

 The process may also be used for making men's belts or garters, 

 and for driving belts. 



U. S. Patent No. 1,100,002, June 16, 1914. Granted to C. L. 

 Van Ness, of Akron, Ohio. Mr. Van Ness has invented a mul- 

 tiple insulating head for application to forcing machines, by mean> 

 of which several wires may be covered with rubber simul- 

 taneously. The head has six dies, each of which is adjustable 

 independently of the others. It is provided with cooling cham- 

 bers and may be adjusted so that the dies lie at any an.gle from 



curing tires, in which the bearing members for the hydraulic ram 

 arc accessible from the outside, eliminating the necessity for 

 taking down the press or going into the vulcanizing chamber. 



U. S. Patent No. 1,101,053, June 23, 1914. Granted to W. L. 

 and O. Bland, of Chicago, Illinois. This is a molding machine 

 adapted to mold rubber articles without flashing the material from 

 the dies and forming ribs or fins on the finished product. The 

 drawings of this device illustrate the machine with dies for mold- 

 ing telephone receivers. The material is fed into a hopper and 

 forced by a conveying screw, like a tubing machine, into feeding 

 channels, and from there into the dies. The parts of the mold 

 are forced together by four hydraulic presses, one on each side, 

 one at the top and one at the bottom of the machine. 



U. S. Patent No. 1,101,555, June 30, 1914. Granted to C. Kuent- 

 zel and assigned to the Goodyear Tire & Rubber Co., of Akron. 

 Ohio. This is a machine for wrapping and unwrapping tires be- 

 fore and after vulcanizing. It may also be used for wrapping 

 tires with paper for shipment, and also for covering rolls of wire 

 and cable. The machine is similar to Kuentzel Patent No. 1.079,- 

 601, which was described in the February- issue of The India 

 Rubber World. The present machine differs from the former 

 principally in minor details of construction, such as the holding 

 device for the tires and the method of drive. 



U. S. Patent No. J, 101,732, June 30, 1914. Granted to Henry J. 

 Doughty and assigned to the Doughty Tire Co., of Portland. 

 Maine. This invention is a combination tire mold and vulcaniz- 

 ing press. The mold is made in three parts and the core in eight 

 segments. The tire is first roughly built up into the desired form 

 and placed in the center mold section, which covers the tread 

 portion. The press operates by hydraulic power, and when pres- 

 sure is admitted four of the core segments are first expanded 

 into the tire and the remaining four segments are then forced be- 

 tween these to expand the tire against the tread mold. The press 

 is then operated to force the upper and lower mold sections to- 

 gether, completely enclosing the tire, after which steam is turned 

 into heating chambers surrounding the mold. 



U. S. Patent No. 1.102.178, June 30, 1914. Granted to W. B.
