types are constructed with capacities of SO to 200 gallons- and are 

 tilted to discharge their contents. The cylindrical or non-tilting 

 types of 50 to 1,000 gallons capacity are discharged through bot- 

 tom gates. (The East Iron &• Machine Co., Lima, Ohio.) 



TWO-HEAD VERTICAL STRANDING MACHINE. 



The accompanying illustration represents a 30-reel 2-head 

 vertical stranding machine for stranding copper wires from No. 

 28 to No. 36 B. & S. 

 gage. It is designed to 

 take metal spools 3J4 ty 

 2.>4 inches, on which the 

 manufacturers ship the 

 wire, thus doing away 

 with respooling. The 

 lower head carries 12 

 reels and the upper head 

 18 reels. The heads are 

 arranged to run in oppo- 

 site directions at a ratio 

 of 4 to 5, and also in the 

 same direction at the 

 same speed. 



The machine is driven 

 by tight and loose pul- 

 leys, and is equipped 

 with a stop motion 

 which stops the machine 

 when any wire breaks 

 or the reels run out. The 

 iidn and loose pulleys 

 arc 6 by 1J4 inches and 

 run 325 r.p.m. This 

 L,'ives a speed of the 

 lower disk of 215 r.p.m. 

 and that of the upper disk 175 r.p.m. The take-up sheave is 8 

 inches in diameter, and a complete set of change gears is pro- 

 vided for different lays. The bench space of the machine is 2 

 feet 8 inches by 1 foot 9 inches. (New England Butt Co., 

 Providence, Rhode Island.) 



RODLESS HYDRAULIC VULCANIZING PRESS. 



The rodless hydraulic press has been perfected to overcome 

 the defects of the old style presses with threaded rods on which 

 the nuts arc constantly working loose, thereby throwing the 

 platens out of parallel, 

 injuring the work, and 

 forcing two of the rods 

 to bear the entire load. 



In the rodless press 

 the cylinder, cheek pieces 

 and top head are one 

 solid open-hearth steel 

 casting. The cylinder 

 and lower face of the 

 top head are machined 

 at one setting, thus in- 

 suring perfectly parallel 

 surfaces between the 

 platens. This construc- 

 tion secures absolute 

 rigidity as there are no 

 parts to work loose. 

 Another improvement 

 over the ordinary press 

 is found in the copper- 

 lined cylinder which 

 makes a perfect surface 

 for the packing of the 

 ram to slide upon. With- 

 I out this copper lining the

short time become cor- 

 roded and rapidly wear out the packing requiring frequent re- 

 placement. 



Where the platens are steam-heated, cooling ribs are cast upon 

 those that contact with the head and ram platens, thus preventing 

 overheating of the top head and ram. 



To vary the opening of a rod-press, dependence is placed on 

 adjustment of nuts on the rods. In the rodless construction a 

 series of rings is placed between the top plate and the head. 

 These are made in multiples of an inch, are instantly removable, 

 and without adjustment the plates must come parallel. (The 

 Charles Burroughs Co., 141 Commercial street. Newark, New 

 Jersey.) 



A NOVEL RUBBER CEMENT DISPENSER. 



The rubber cement dispenser here shown has been recently 



perfected and will undoubtedly become popular with users of 



rubber cement, due to the saving of labor and conservation of 



cement obtained by the construc- 



gr-'--»^ tion of this device. 



1 [ill "III ,->r>^<:^^ These containers, ranging in

'^—J'tJ' V___1 ^ h maimer and closed by a screw 



cap. thus keeping the contents in 



good condition until used. The 



cement feeds from the bottom of 



the container to the brush cup, 



thereby permitting the use of 



settling compounds with uniform 



results, avoiding the waste common to ordinary containers. 



The brush is protected by being immersed in the cement when 

 not in use and a disk that prevents the cement from reaching 

 the handle of the brush, acts as a cover to the cement cup. (W. 

 H. McNutt, 83 Chambers street, New York City.)
