Title: Improvements in Electrical Recording Devices.
Inventor: HARRISON GEORGE
Filed: 1905-07-06
Granted: 1905-11-23
Abstract: 13,953. Harrison, G., [Electric Railway Improvement Co.]. July 6. Registering observations by instruments. - In recording-apparatus in which record sheets are perforated by electric sparks, a condenser is connected in parallel with the spark circuit to render the sparks sufficiently violent to make distinct lesions in ordinary fibrous paper, and the spark circuit is periodically interrupted in order to avoid charring or burning the paper when the pointer remains quiescent for some time. The apparatus is described as applied to record the resistance of rail-bonds on electric railways. A volt-meter C connected to brushes a mounted on a truck A has its pointer insulated by a section c<1> of broomstraw or other material. The pointer moves over but not in contact with a conductor E and a series of wires g, the lower ends of which are arranged in a row above a slot h in a strip H of insulating- material on a metal bar J. The paper is wound over the strip H by rollers l driven from a truck wheel. The condenser S is connected to the terminals of the secondary coil K<1>. The circuitbreaker of the induction coil may be in the form of a rotating commutator, to the shaft of which is attached an arm passing across four contactplates connected in pairs between the coil K<1> and the plate E.

Title: Improvements in the Manufacture of Cold Drawn Steel and other Metal Tubes and in Machinery or Apparatus to be employed in the said Manufacture.
Inventor: DOLLMAN HUBERT
Filed: 1905-07-26
Granted: 1905-11-16
Abstract: 15,351. Dollman, H. July 26. Drawing.-In order that an ingot may be colddrawn into a pipe for cycles &c. without waste, one end 26 of the pipe is drawn to the finished size and then held in a gripper 30 while the remainder is drawn down. During the first operation, the pipe 3 is held in a vice 2 and acted on by a loose die 13 and a headed mandrel 15 carried by a screwreciprocated eaddle 8. When the saddle 8 moves to the left, the die 13 bears against the horns 12 and reduces both the external and internal diameters of the pipe end, but on the return of the saddle the die bears against the horns 11, and the thickness of the pipe wall is reduced between the die and the mandrel head 16. The pipe, instead of the saddle, may be reciprocated. A tapered plug 25 of oval section is driven into the finished end of the pipe, which is passed through the hole with enlarged sides in the gripper 30, turned axially through a right-angle, and slightly withdrawn so as to be gripped as shown in Fig. 10. The drawing is completed by means of a die 27 and mandrel 29, the thickness of the wall of the second-drawn part being the same as or different from that of the first-drawn part. The oval end of the tube is restored to its original shape by means of a round drift or mandrel.

Title: Improvements in Variable Speed Gearing for Motor Vehicles, Velocipedes, or the like.
Inventor: HANNIBAL JAMES
Filed: 1905-09-12
Granted: 1906-06-14
Abstract: 18,395. Hannibal, J. Sept. 12. Motor road vehicles.- Relates to variable gearing for motor-vehicles, of the type in which two separate epicyclic trains are employed for high and low speeds respectively, the intermediate speed being a solid rotation of the parts. A driving-sleeve D rides on ball bearings between a fixed axle B and the hub A to be driven. Sun pinions C, E are mounted side by side so as to slide on the axle B, and a disk F carrying two sets of planet pinions G, H rotates independently of the sleeve D and hub A. The pinions G mesh with the pinions C and with an internally-toothed ring A<3> upon the hub A. The pinions H mesh with the pinion E and with a similar ring D<2> upon the sleeve D. The different gears are obtained by locking both pinions C, E to the carrier F or one to the carrier F and the other to the axle B. The central aperture of the carrier F is of the same shape as the exterior of the pinions C, E so as to engage them both in their mid-position. Clutch members C', E<1> fixed to the axle B are similarly formed to hold the pinions C, E, respectively, when these pinions are slid outwards. The operating- mechanism is shown in Fig. 2. Springs J normally hold the pinions C, E in their mid-position. The axle B is hollow and contains a rod L which carries at the end of a spring N a pin K projecting between the pinions C, E. The internal teeth upon the carrier F are arranged to break joint so as to form a stop for the pinions. When the rod L is pulled to the left by the chain L<1>, the pinion E is stopped and the pinion C is drawn into the member C<1>. When the chain L<1> is released, the member C is thrust over by its spring J and the pinion E is thrust into the member E' by a spring M. In one modification, a free-wheel clutch is interposed between the ring A<3> and the hub A so that in free-wheeling the gearing is cut out. In another modification, the rings A<3>, D<2> are carried by the member F, the pinions G by the hub A, and the pinions H by the driving-sleeve D.

Granted: 1906-01-25
Abstract: 20,591. Schmick, H. J. Oct. 11. Pulley - blocks.- Relates to hoisting- devices, and more particularly to the gearing thereof. In the construction shown in Fig. 2, the hand chainwheel 5 and a head 2 revolve together. On the face of the head 2 are projecting members 14, Fig. 5, engaging the worm or gear wheel 15 on the shaft of the load wheel or drum. The members 14 are cycloidal in form, and, in order to prevent binding, the angle of the outer faces is made to increase constantly from the root to the point of the teeth, while the angle of the inner faces diminishes constantly in the same ratio. A wheel 25, provided with internal ratchet teeth and under the control of a spring-controlled brake block 29, is locked to the head 2 when lowering by a spring pawl 27, so as to sustain the load. In a modification, Fig. 6, the self-sustaining gear is dispensed with, the load being supported directly by the projections 14 on the head 2, which is driven from a crown pinion 35.

Granted: 1908-03-26
Abstract: 7643. Sayers, W. B. March 30. Elastic-fluid turbines.-Relates to turbines of the type described in Specification No. 297, A.D. 1906, in which buckets are formed on the periphery of a rotor, and guide-passages are arranged in a surrounding stator in such a way that the steam traverses a forwardly - progressing spiral path between the inlet and exhaust ports. The improvement lies in providing additional guide-passages in the stator so that part of the steam traverses a rearwardlyprogressing spiral path. The Figure shows a group of rotor buckets and two inlets a, a<1>. Passages c in the stator lead the steam exhausting from one side of the buckets back again to impact repeatedly before reaching the exhausts b, b<1>. Similar passages c<1> are arranged to lead steam in a rearward direction with repeated impacts until the exhausts b<1>, b are reached. The construction prevents backward leakage between inlets and exhaust ports, and increases the effective extent of rotor periphery. No stagnant steam exists in the buckets to absorb the energy of the fresh steam. The number of inlets and outlets is not restricted to two.

Abstract: 1 1 , 0 6 8. Kosak, K., and Herz, R. May 11. Vacuum cleaning-apparatus.-The washing-water for purifying the dust-laden air is circulated in a closed circuit by the pump producing the vacuum, and the mixture of dust-laden air and washing- water is drawn from the washer to the pump through an hydraulic seal. The washer a, provided with a dirt discharge passage w opening into a reservoir r, communicates by way of an hydraulic seal d and pipe c with the suction side of a doubleacting pump b, the discharge valves 13,14 of which open into a water tank v open to the atmosphere. The tank communicates by a pipe g with a nozzle m at the top of the washer. The pump produces a vacuum in the vessel a, drawing in dust-laden air, through the pipe h, and water, through the nozzle m, which are thoroughly mixed by means of baffles 3, 8, 9, nozzles 2, 5, 7, and overflow plates 4, 6 provided with deep recesses at their edges. Most of the dust is precipitated, while a mixture of air and water is pumped into the tank v, from which the air escapes freely ; the mud sinks to the bottom, and the water continues to circulate. In order to maintain the proper relative amounts of washing- water and dust-laden air, the width of the aperture of the nozzle m is controlled in accordance with the vacuum in the vessel a, by means of a membrane n connected to the pivoted wall p of the nozzle, or in accordance with the water level in the bottom of the vessel a, by means of a float connected with the pivoted wall.
