Title: Improvements in or connected with the Manufacture and Storage of Acetylene Gas.
Inventor: OWENS WILLIAM
Filed: 1898-01-20
Granted: 1898-07-30
Abstract: 1625. Owens, W. Jan. 20. Acetylene.-Carbide is contained in a number of trays 10 in a tube 9 which is inserted in the lower end of an inclined generator 6 and secured by a cover 13. Water is supplied by a tank 5 through a valve 4, which is opened by the bell of the gas holder, the trap 8, and pipe 26 to one tray after another through the channel 12, Fig. 2. The gas escapes through a pipe to the bottom of the purifier 15, and rising among the baffles 16, down which water runs, escapes by the pipe 20 into the dome 21 at the top of the gas holder. The pipe 26 is provided with a stop-cock 7 which can be closed when it is desired to recharge the generator. A safety escape pipe 24 leads away from the gas holder. When the generator is exhausted, it becomes filled with water, and the water continues to rise in the trap 8 till it flows through a pipe 25 to another generator.

Title: Improvements in Rasp Cutting Machines.
Inventor: MCHARDY JAMES ALFRED
Filed: 1898-06-13
Granted: 1898-10-08
Abstract: 13,200. McHardy, J. A. June 13. Rasp-cutting machines. -The blank 1 is held down on its bed 2 by the finger 4 connected to the weighted lever 8. The bed 2 is fed by the screw 14 and nut 13, which may be thrown out of action by the spring rod 15 and links 16. The screw is acted on by a spiral spring 21, and is released at intervals, so as to turn suddenly, by one or other of the two pawls 35, 36, which engage with the ratchet-wheel 33 on the screw and are alternately released by a cam 34 on a constantly - rotating drum 22. The drum serves continually to wind up the spring 21, which unwinds at intervals. The drum is rotated by a worm 24. This intermittent spring mechanism may be variously modified. The cutter 40 is adjusted on the carriage 56, which slides laterally on the head 41 pivoted and adjustably clamped to the arm 42 of the bell-crank lever 42, 52 worked by a crank on the shaft 32. The cutter thus describes an arc round the centre 44. The carriage 56 is fed laterally by a slide 61 acting on the arm 62 fixed to the carriage 56. The slide 61 is worked by a lever 70 pivoted at its centre and at one end to a slide 72 worked by a cam 74 on a shaft 88 which has a step-by-step rotation imparted by pawl and ratchet mechanism. At any two of the three pivots of the lever the lever has a sliding as well as a turning movement. The fulcrum of the lever can be adjusted so as to vary the lateral feed of the cutter by adjusting the support 76.

Abstract: 15,759. Sutro, L. July 19. Bindings.-In shirt facings or edgings consisting of a braided tape A woven about a rope-like core C, Fig. 1, the core is retained in place and prevented from sagging when the edging frays by covering it with a gutta-percha tape D, or by coating it with a waterproof adhesive solution. The adhesion to the surrounding parts is sufficient to keep the core in place. Fig. 2 shows the effect which it is desired to prevent.
Patent GB-189817449-A (GB)
Title: Improvements in Acetylene Gas Generators.
Inventor: MANGER THEODOR
Filed: 1898-08-13
Granted: 1898-10-08
Abstract: 17,449. Manger, T. Aug. 13. Acetylene.-Water is supplied from a pipe 6 through a cock 5 to a pipe 1 pivoted thereon, which is weighted at 2 so as to press at the other end against an arm 3 projecting from the bell 4 of the gas holder. As the bell rises and falls, the cock 5 is shut and opened respectively, so that the supply of water is controlled by the consumption of the gas. The water falls into a funnel 7, and passes thence by a cock 10 to the generator 8. When this generator is exhausted and the bell 4 consequently descends to a lower position, the cock 10 is turned by a chain 9 connected with the pipe 1 so as to direct the water into the generator 12. The gas passes from the generators to a washing- chamber 13, and thence by a pipe 14 to the holder.

Title: Improvements in Knitting Machines.
Inventor: WILDMAN FRANK BLACK
Filed: 1898-11-01
Granted: 1899-01-14
Abstract: 22,963. Wildman, F. B. Nov. 1. Circular knitting-machines.-Instead of a pattern chain, a disc D with projections d', which acts on a lever S<4> and so raises or lowers a shaft S and moves the knitting-cams, is used. On the same shaft as the disc D are fast and loose ratchetwheels E, F. A loose pinion G is fixed, or connected by friction plates, with the wheel F, and gears with a wheel P on the same shaft as a card wheel I'. The fabric passes between the card wheel I' and a fluted roller L to the take-up rolls C operated by the rope C<1>. As the fabric descends, it drives the wheel I', and so drives the ratchet F independently of E. The wheel E has alternately deep and shallow teeth, and the pawl H, which is operated by a slide H' and engages both ratchets, drives E twice as quickly as F. A number of segments J hold the pawl out of gear with F. Segments K, K<1>, adjustable on the wheel F, act similarly. At certain places the wheel E has two low teeth e, e<3> ; when the segments K, K<1> are under the pawl, the wheel F is slowly fed by the fabric, and the pattern disc remains at rest till the segment K or K<1> has passed the pawl, when the pawl engages and drives both wheels. A guard I<3> on an arm I<4> and a casing P protect the card wheel I' and the pattern ratchets. By means of a handle M and milled head Q, and suitable stops on a pivoted lever N', the ratchets E, F can be set in the initial position ready to commence a pattern.

Granted: 1899-05-27
Abstract: 8470. Lehmann, E. P. April 22. Mechanical toys.-Means are provided for producing by the same mechanism which imparts motion to the toy a squeaking, croaking, quacking, or similar sound. The toy may take the form of a human being or other creature, such as, for instance, that of a frog. To produce the sounds, a rod e with roughened surface is reciprocated over the edges of the hole in a membrane, secured by a hoop d, which encloses one or both ends of the drum b. As represented, the elbow lever f, actuated by the inflation or deflation of the rubber ball h, or by other suitable means, draws the rod e in one direction, the return movement being effected by the contraction of the spring g. The lever, being suitably connected with some portion of the animal, as for instance the legs, causes the progression.

The rim of each pulley is made up of a series of jointed linksj, in the form of an endless lazy-tongs, which is secured upon radially-adjustable cross-bars m. In the construction shown in Fig. 4, one end of each cross-bar is fitted in a radial slot n in a disc o, fixed to the shaft, and a pin, fixed in a central lug, works in a curved slot in an arm s, pivoted near the centre of the disc. By turning 'the arms, the cross-bars are moved radially ; this is effected by forming on their bosses toothed segments adapted to gear with a circular rack on the sleeve h. The sleeve is moved to and fro by a shaft c, pinion u, and a rack attached to it. In the form shown in Fig. 6, eyes are formed at the ends of the cross-bars to engage with inclined guide-rods 2, secured in bosses 3, which may be moved together or apart along the shaft. In a modification, the slotted disc of Fig. 4 is used in combination with one set of the inclined guide-rods of Fig. 6. Fig. 1 shows how a pair of pulleys may be simultaneously adjusted by a transverse shaft c having pinions at each end, one above, and the other below, the sleeve to be moved. In another arrangement, the two sleeves are coupled by a lever pivoted midway between them.. In connection with the pulley shown in Fig 6, two such levers, operated by a shaft with right and left handed screw-threads, are used.
