Title: Improvements in and relating to the Manufacture of Sheet Metal Spokes for Pulleys.
Inventor: CHARLES A. BRINLEY
Filed: 1899-07-28
Granted: 1899-09-09
Abstract: 15,510. Lake, H. H., [Brinley, C. A.]. July 28. Stamping; bending. - Sheet-metal spokes for pulleys are pressed into shape from a blank, Fig. 3. having three tongues M. The strip N is first bent at right-angles to the tongues, and the blank is then operated on by semicircular dies B, G, Fig. 1, which give it the shape shown in Fig. 7, N<1> being the semi-hub. The die B is held by clamps D, and rests on a liner or packing-piece C of suitable thickness. The faces b of the dies are slightly oblique, to give the spokes a set as shown. The diagonal action of the dies relatively to the spokes effects the levelling of the edge n on the liner C. A liner I is also provided for the upper die. The liner C may be dispensed with.

Title: Improvements in and relating to Electric Incandescence Lamps.
Inventor: FEENY VICTOR ISIDORE
Filed: 1899-09-01
Granted: 1899-11-25
Abstract: 17,707. Feeny, V. I., [Allgemeine Elektricitõts Gesellschaft]. Sept. 1. Incandescent lamps. -Several rods G<1>, G<2>, G<3>, or tubes, or other bodies, of material of high resistance a t ordinary temperatures, are connected in parallel with one another, and the group is connected in series with iron wire or other resistance sufficient to steady the current taken by one rod, from a supply at constant pressure. The lamp is started by coils H heating all the rods, so that they become conductive, but the series resistance then keeps the pressure applied to the rods so low that all become cold except the hottest one, which becomes incandescent. When a rod is worn out, another comes into operation, each rod in the group thus acting successively. The rods are fixed so far apart that one cannot heat another. The Specification refers to another arrangement of lamp, in which several parallel rods are placed so near together that they heat one another, and all incandesce simultaneously, the material preferred being a mixture conductive at low temperatures.

Title: Improvements in Machines for Bending Links and the like.
Inventor: ATTWOOD ELI
Filed: 1901-02-04
Granted: 1901-06-22
Abstract: 2395. Attwood, E. Feb. 4. Bending.-A machine for bending chain links and the like has a mandrel shaft 4, mounted in a frame 2, and driven by spur gearing 8 from a countershaft (not shown). The wheel 8 is loose on the shaft, and can be clutched thereto by pins 48, projecting through the wheel and engaging projections 46 on a disc 45 keyed on the shaft. The pins have grooved beads engaging slots in a sliding collar 43 operated by levers 39, 37, a rod 36, and treadle 35. The shaft 4 has a head 25 on which is fixed a mandrel block 26 with a sliding portion 27 to complete the mandrel for the link. The blocks are formed with a continuous helical groove 33 to bring the ends of the links adjacent but in different planes. The rod or bar is inserted between the mandrel and a grooved follower 22, and the treadle depressed to start the machine. After one revolution the treadle is released, and the clutch disengaged by a spring to stop the machine. The portion 27 can be slid off to allow the link to be removed or other blocks to be used for different links. The follower is mounted on an arm 14, pivoted at 19, and rocked by an eccentric 12 on a shaft 11 to keep the follower against the bar, and the bar against the mandrel. A spring 23 presses the follower against the helical face of the mandrel.

Title: Improvements in Machinery for Compressing Air or other Elastic Fluids.
Inventor: WATSON HENRY BURNETT
Filed: 1901-02-13
Granted: 1902-02-13
Abstract: 3081. Watson, H. B., and Billetop, T. C. Feb. 13. Compressing.-The compressor works at high speed and in two or three stages. The air enters the cylinder 2 through valves 16, and escapes through valves 17 in the piston 9 on its up-stroke into the chamber 18 above the fixed piston 10. Hence, after further compression, it escapes to the cooling-coil or through the valve 19 to the third cylinder 14, whence it is expelled by the plunger 15 through a valve and the cooling-coil 21. A piston 5, attached to the same crosshead as the piston 9, serves to circulate the cooling-water, which enters at 13, passes through the passages 12 to the chamber 26, and then between helical baffles 28 to the outlet 27. The parts which move through the water are made narrow at their ends to prevent impact. The entering air is moistened with distilled water sprayed from the pipe 24. The water or moisture, which is separated or drained from the compressed air by means of a separator, is led through a pipe 29, Fig. 4, into a draining-device consisting of a tubular chamber divided into graduated compartments by diaphragms 30 having graduated openings 32, the compartments and openings growing larger towards the outlet 33. The inclination of the draining-device is indicated by the horizontal dotted line C-C.

Title: Improvements in Typewriting Machines.
Inventor: FELL JOHN CORRY
Filed: 1901-04-23
Granted: 1901-05-25
Abstract: 8346. Fell, J. C., [Union Typewriter Co.]. April 23. Typewriters.-The key levers E are pivoted beneath the fulcrum bar F, and are guided by combs G, G<1> and tensioned by springs H. The type-bars J are pivoted in a segmental bearing composed of a front plate K and a back plate K<3>. The front and back plates are slotted radially to receive the type-bar hubs, and the front plate is formed with a rounded groove K<2> to take the typebar pivots J<1>, Fig. 5. In front of the segmental bearing for the type-bars are two depending brackets or plates M, to which are secured bearings for rock-shafts intermediate between the key levers and the type-bars. Fig. 3 shows a part of one of the plates M with two of the bearings M<1> for the rock-shafts N. Each rock-shaft has two arms N<1>, N<2>, of which one is connected to the type-bar by a link O, and the other is connected to the key lever by a link P. Springs Q tension the arms N<1> rearwardly. The type-bars enter a forked guide S just before striking the platen. The guide serves also as a support for the inking-ribbon T, and is adapted to be rocked on its pivots U to cause the ribbon to approach the platen when a key is struck. A universal bar V<3> is linked to a beli-crank lever V formed with a cam.groove V<4> so shaped that the guide S approaches the platen before the type-bar reaches it, and remains there until the bar has escaped from the guide on its return movement. The type-bars are formed by soldering together two similar halves stamped from thin metal. The stamped bosses which form the hub enclose between them the enlarged central portion of the pivot J', which is thus immovably secured in the type bar. Ribs J\ Fig. 3, stiffen the bar.

A ratchet-wheel D and pawl D<1> prevent backward motion. The pawl D<1> is retained in either its operative or inoperative position by means of a spring D<3>, Fig. 5. On the rotation of the drum the apparatus travels along the rope, thus pulling on the end of the rope, which is secured to one of the bolts H<2>.

Title: Improved Process for Reducing Indigo.

Filed: 1902-03-03
Granted: 1903-01-22
Abstract: 5277. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. March 3. Dyes, artificial; dyes from natural products.- Indigo is reduced to indigo-white by acting upon it in the presence of a warm (70‹-80‹C.) sulphite solution with an electric current. A solid indigowhite preparation, fairly stable to air, is obtained directly, if the liquid is not allowed to become more than very feebly alkaline, otherwise the indigo-white dissolves, forming an indigo vat. In one example, mixed sodium sulphite and bisulphite solutions are used in the cathode compartment, and 10 per cent. sulphuric acid in the anode compartment. In another case, sodium bisulphite only is used in the cathode compartment and potassium sulphate solution in the anode compartment, and if the alkali produced in the cathode compartment is neutralized by adding bisulphite or passing in sulphur dioxide, indigo-white is precipitated. In a third example no diaphragm is employed, and mixed sulphite and bisulphite solutions are used.
