Title: Improvements in Apparatus for Generating Acetylene Gas.
Inventor: WALLIN BOO HENNING
Filed: 1898-09-22
Granted: 1899-08-12
Abstract: 20,122. Wallin, B. H., and Wendel, Baron R. de. Sept. 22. Acetylene.-Apparatus for generating acetylene in which the carbide is automatically supplied. The carbide is made up into cylindrical cartridges, which are carried by a band or ribbon 3, the inner end of which is attached to a shaft A, around which the band is then wound so as to form a spiral magazine enclosing the cartridges. The shaft 4 is carried by a lever 17 having a handle 18 and pivoted on a shaft 48, around which the band 3 is wound as it unwinds from the shaft A under the pull of the weight 11. The cartridges fall into the top of the shoot 6. The gas-holder bell 12 has a guide-rod 13 upon which are steel points 14. As the bell falls, these pins operate double pawls 15, which are thereby removed from a ratchet or cam disc 16. Mounted upon the same shaft as the ratchet disc 16 is a pinion 10 gearing with one of a pair of star-wheels 7 on the shafts of which are toothed wheels 9 gearing together. The star-wheels engage with the cartridges one at a time, and pass them down the shoot 6 to one of the two semicircular generators 22, 23, whenever the pawls release the disc 16. The generators may be rotated around a vertical shaft, so that one may be cleaned out while the other is in use. Instead of being contained in cylindrical wrappers, the carbide may be carried in shallow oblong frames having pivots at each end, which are carried by a slotted bar while the carbide is being discharged down the shoot. The frames are carried by the spirally-wound ribbon as above. A gas-escape pipe 56 to the atmosphere is provided to the gas collector 41. In a modification, a pawl having two hooks is operated by pins on a rod connected to the gas bell and moving upwards and downwards in a tube, and one or more vertical tubes arranged above the shoot take the place of the spiral magazine. The lower ends of these tubes are provided with spring-pressed lower closing-devices, which are used while the tubes are being refilled with cartridges. The generators are also differently arranged, so that they may be taken out of the containing-vessel for cleaning out, handles and hooks being provided for this purpose. The Provisional Specification describes the use, for drying the gas, of calcium carbide, a four-way valve being used to control the direction of the gas.

Title: Improvements relating to the Manufacture of Rimmed Wheels, Discs, and the like
Inventor: WILLIAMS EDWARD
Filed: 1901-06-19
Granted: 1902-05-15
Abstract: 12,489. Williams, E. June 19. Rolling.-Rimmed wheels or discs are formed from plain circular sheet-metal blanks by rolling the edge by means of a forming-roll i, Fig. 6, carried round the blank while clamped between blocks k. The roll carrier h is secured to a wheel c, freely mounted on a fixed pivot a and driven by gearing g,f, e from belt pulleys d. The clamping of the blank j is effected by a screwed ram l engaging in a nut in a worm-wheel m driven in either direction by pulleys o which can be separately clutched to the worm shaft n, the driving-belts slipping when the clamping pressure is sufficient. The forming-roll is mounted on a slide q on the carrier, the slide being fed inwards during operation by a cam on a spindle z bearing against a roller 1 on the slide. The cam spindle is driven by worm gearing y, x, and bevel gearing (not shown) from a vertical shaft carried by the wheel c and having a pinion t engaging a fixed wheel r. When the inward feed of the slide is sufficient to form the rim completely, a stop 5 on the worm-wheel y strikes a lever 4, which trips a pivoted stop 3, allowing the worm x to be drawn out of engagement by a spring 2. The cam spindle can then be rapidly rotated by hand, to allow the finished article to be removed and a fresh blank inserted. The worm gear is then re-engaged by hand, the abutment piece 8 on the lever 4 being pivoted so that it may be raised to clear the stop 5. A pulley 9 on the pulley shaft is provided with an ordinary band brake for quickly stopping the moving parts. Ordinary cutting - tools may be arranged on the carrier to trim automatically the edges of the disc rim after its formation by rolling. The roll may be replaced by a reciprocatory hammer or plunger to impart an intermittent pressure to cause the metal at the periphery of the disc to assume the desired shape.
