can be easily cleaned h\ putting into a bucket of water. The 

 label or strip is drawn under tlic feed roller from the projecting 

 horizontal table and passes out onto the receiving table ready 

 for use. 



By filling the reservoir with gum, the machine can be used to 

 gum labels, and by using water, it can be used to moisten dry 

 gummed labels. Where labels are to be put on packages or 

 boxes such as those containing inner tubes and similar articles 

 this gummer should prove a valuable adjunct to the factory 

 equipment. It is made for labels or strips from '/^ to 16^ inches 

 in width. [W. H. Trabuc, 32 West 83d street, New York City.] 



MACHINE FOR PANNING RUBBER COVERED WIRE. 



This machine "pans" the wire after the rubber has been ap- 

 plied to it for insulation by the tubing machine, and handles all 

 sizes up to No. 6 B. & S. gage. 



Referring to the cut. A is the friction drive that revolves the 

 pan B in wliich the rublicr ccivered wire is coiled. The speed of 



the pan is increased and decreased by the friction drive A, con- 

 trolled by the screw C. Chain D is the drive for the knuckle 

 joint shaft E, and brass tube G, through which the wire runs, is 

 moved back and forth by chain F, while sprocket H drives the 

 rubber feed rolls /. 



The rubber covering machine and the above device are driven 

 together so that when the variable speed cones are adjusted for 

 the speed at which the wire is to be delivered, it will be coiled 

 layer for layer in the pan. Then talc or soapstone is sifted over 

 each layer, after which the covered wire is ready for vul- 

 canization. 



It is claimed by the inventor that the cost of handling wire 

 may be materially reduced, and that a maximutn output of a 

 uniform product may he obtained. [T. J. Seward, Bridgeport, 

 Connecticut. 1 



HYDRAULIC VALVE FOR RUBBER MILLS. 



'I'his hydraulic valve is constructed to 

 withstand the hard usage of rubber mill 

 work. It is made of a special bronze 

 composition for pressures up to 2,500 

 pounds per square inch. There are only 

 four parts to the valve ; all parts being 

 made extra large, the specially packed 

 stem, large hand wheel or lever furnished 

 makes the valve an easy one to operate.

A GARVIN HARD RUBBER LATHE. 



In the manufacture of hard rubber |)umps, piping and fittings, 

 the lathe here illustrated is frequently used. It is known 

 as a No. 1 screw cutting lathe and has a plain turret head, auto- 

 matic collet and a bar feed. Two solid floor legs support the 

 bed of the lathe, which is of box form, and the pan which is fit- 

 ted with double strainers, and oil or water reservoir. The spindle 

 is hollow and will admit rods up to 5^ inch in diameter, with 

 the liar feed attaclinient, and rods 13/16 inch in diameter, without 



the bar toed, Tlu- collet that helds the work is opened and 

 closed by a hand lever. When it is open the feed advances the 

 rod through the spindle and against the stop in the turret head 

 which determines the length of stock to be turned. The cross 

 slide carries a front and back tool post and is operated by a 

 hand lever. The turret head is A^ inches in diameter and has 

 six 11/16 holes for tools, it revolves by hand in either direction 

 and long rods up to '2 inch in diameter can be passed freely 

 through it. 



The machine occupies a floor space of 42 x 22 inches and is 

 driven by a three-step cone pulley from a double friction 

 countershaft that is supplied with the lathe. [Garvin Ma-

MACHINERY PATENTS. 



PRICES DIPPING AND VULCANIZING APPARATUS. 



In this machine, tlie forms are dipped and then subjected to the 



action of a partial vacuum to aid in the evaporation of the 



solvent while at the same time they are heated from the inside to 



further increase 



evaporation. 



The accompany- 

 ing cut shows a 

 hermetically sealed 

 chamber A in which 

 the forms B are 

 mounted on nipples 

 C. Steam is ad- 

 mitted to the forms through the hollow support D and the rubber 

 solution E is forced into the chamber through pipe F. The dip- 

 ping, which is accomplished by turning the handle G. is repeated 

 a suitable number of times before the rubber solution is with- 

 drawn into a nearby container. .A.t this stage a vacuum is pro- 

 duced through pipe H, the effect of which is to produce a very 

 rapid evaporation of the solvent and drying of the coating on the 

 forms.
