NIPPLE BEAD FORMING MACHINE. 



Beads on nipples, medicine dropper bulbs, linger cots and sim- 

 ilar articles are at present formed by hand, or in a mold. 

 Mahoney's invention provides means whereby this work- 

 may be done _^ 



mechanically in J T 9 



a rapid, eco- " i" — 



nomical and ac- 

 curate manner. 



In the accom- 

 panying plan 

 view, the bodies 

 of the nipples.^, 

 which are un- 

 vulcanized, are 

 molded on the 

 forms B. As the 

 heads D on the 

 operating rods 



I not shown) are brought into engagement with the cam plate 

 /;. the forms are applied to the chucks C. Then as the chucks 

 pass out of engagement with the cam plate, the forms are clamped 

 ill place and both the form and chuck are rotated so that the 

 forming roller F is brought into engagement with the form. The 

 action of the roller is to turn the rough edge of the nipple out- 

 wardly, thus causing it to roll upon itself and form the desired 

 l.t-art [J. L. Mahoney. United States patent No. 1.154,191.) 



EOYLE'S MULTIPLE TUBING MACHINE HEAD. 



This new tubing machine head is designed for the manufac- 

 ture of a honeycomb pneumatic tube i 

 for multi-perforated tubes in general 

 tlie machine A is the stock worm 

 jacket. The die £) is 

 lield by the holder E and , ' 



the tubular nut F. Into 

 the web G of core bridge 

 H is secured a gang of 

 cores / with their free 

 ends extending to the 

 outer end of the die D. 

 .\nother gang of cores / 

 is secured into the web 



of the other bridge K, their ends also projecting outward 

 die. The inner ends of the core members pass through holes 

 ill the bridge webs and are secured, by nuts screwed on their 

 threaded inner ends. 



The core members of the two gangs alternate in such a manner 

 .l^ to bring the outer ends of the two gangs in the desired rela- 

 tion to one another to produce the honeycomb structure desired. 

 A V-shaped opening, shown in the front elevation, is made along 

 tlie inner side of the tire by locating a tapered projection L at 

 the mouth of the die. This opening is serviceable in applying 

 the casing and tube section therein to the rim. (Vernon Royle. 

 L'nited States patent No. 1,152,978.) 



MEADE'S MULTIPLE SPREADING AND DOUBLING APPARATUS. 



In the illustration ./ and h are two rolls of fabric. From .( 

 the fabric .A^ passes upward to spreader C, and from the gage 

 knife D receives a light coat of waterproofing. It is dried by 

 ^team coils /i as it passes up and around idler rollers to another 

 spreader /•", where it receives a heavier coating. The fabric O. 

 irom roll /?. passes through a doubling device (/'. Here the two 



fabrics are pressed together lightly and at // a second doubling 

 device brings the two layers of fabric together without endanger- 

 ing the exposed surfaces. The goods are then passed over the 

 heating drum /. after which they pass under the hood / into an 

 upward current of air. .\t A' is another duubler where heavy 



pressure is exerted on the goods, which then pass through the 

 measuring device L and are wound on the core M. | James Meade,
