THE BRUSH CLOTH STRETCHER. 



Many kinds of fabrics are used in making certain rubber prod- 

 ucts, and require special treatment before and after calendering 

 or proofing, that of stretching being quite important. For this 

 purpose the brush cloth-stretcher here pictured is recommended, 

 as it smooths out the cloth and improves the finish of the goods. 

 It is used to advantage on balloon cloth during the process of 

 coating, and works equally well for stretching and removing 

 wrinkles from tire-building fabric, breaker fabric, sheetings, 

 drills and stockinet. Rubberized materials or tacky goods can be 

 smoothed and stretched on this machine, without damage to 

 finish, during the process of spreading. 



The principle of stretching cloth from the center toward the 

 selvedge with this device is said to differ from that of any other 

 employed for a similar purpose. The bristled rolls are made 

 up of disk units, into which the bristles are set at an anK't- 



Thrown Off Drum or C.vlender Roll 



These disks are assembled and firmly locked upon a shaft, so that 

 the bristles point outward from the center of the shaft. The 

 mounted shafts are hung upon a frame designed to allow the 

 application of the bristled rolls to the drying cylinders or cal- 

 ender rolls or other surface, at any desired pressure, which is 

 regulated according to the nature of the fabric to be stretched 

 and the amount of stretch desired. An important feature of 

 this stretcher is that it does not require to be threaded-up. The 

 cloth is run on the calender roll or drum in the usual way, and 

 the stretcher rolls are brought in contact with the goods. They 

 may be quickly removed by a simple adjustment device. The 

 stretcher rolls are not mechanically driven, but revolve when 

 brought in contact with the moving surface of the goods. Each 

 bristle catches a different thread of the fabric at the same time, 

 which has the effect of pushing the cloth outward from the 

 center toward the selvedge without any undue strain, as the 

 action of the multitude of bristles working in unison is abso- 

 lutely uniform, and the perfect flexibility of the bristles eliminates 

 all possibility of disturbing the finish of the goods in any way.

 PNEUMATIC SHOE-PRESS. 

 IS invention consolidates the parts of a rubber boot or 

 shoe before vulcanization, by the action of compressed air 

 suitable fluid under pressure and control by the operator. 

 The receptacle A is 

 provided with a hinged 

 cover B of the breech- 

 block type. A cup-shaped 

 conoidal last support C 

 is lined with soft rubber 

 that accommodates dif- 

 ferent lasts and seals the 

 ihamber by means of the 

 end of the last. The 

 adjustment for different 

 lengths of lasts is ef- 

 fected by the movement 

 of the last support that 

 slides in the cylinder D. 

 The stem of the last- 

 support has a left-hand 

 thread screwing in the end of E, which has a right-hand screw 

 connection with the cylinder-wall e.xterior and adjustable by 

 handwheel F. A spring plate G forms a back-rest for the 

 lasted shoe. 



A last with a shoe thereon is placed in the chamber with the 

 top of the last resting in the last-support, and the back of the 

 heel resting against the back-rest. The cover is then closed and 

 locked and the compressed air turned into the chamber, its 

 effect being to force the last more tightly into the packing mem- 

 ber and also to press the shoe tightly against the surface of the 

 last. The air between the shoe and the last is e.xpelled through 

 the vent holes and the parts of the shoe are consolidated by 

 the difference between the pressure of the atmosphere on the 

 inside of the last and the external pressure in the chamber. 

 When the operation is completed the chamber is opened and the 

 lasted shoe removed and vulcanized in the usual way. (J. R. 

 Gammeter, Akron, Ohio, assignor to The B. F. Goodrich Co., 

 a corporation of New York, United States patent No. 1,283,144.)
