Granted: 1908-03-26
Abstract: 11,816. Guest, C. H. May 21. Lifting-jacks &c. - Hydraulic jacks are constructed without non-return inlet valves. The .pump plunger is provided with spring rings instead of the usual packing. Fig. 1 is an elevation of the complete jack, and Fig. 2 is a section of the pump on the line A-B, Fig. 1. The pump plunger F is provided with spring rings M. On its upstroke, it creates a partial vacuum in its cylinder until it uncovers the holes N, N<1>; water is then forced in from the reservoir C. When the plunger covers the holes on the down-stroke, the water is forced past the non-returnvalve S and through the pipe T to the ram. To lower the ram, the lock-nut K is slackened, and the water forces its way past the conical seat U into the reservoir.

Abstract: 11,854. Gibbons, W. G. May 22. Signals, hydraulic.-In telemotor apparatus such as is described in Specification No. 12,232, A.D. 1898, the transmitting- cylinder is made initially in one piece, and circumferential ports, or rings of holes, are cut in it at each end of a central portion corresponding to the usual central distance-piece. In Fig. 2 the cylinder A is shown formed with a part B surrounding the central portion D - of the cylinder A to form an annular chamber E, webs C uniting the central portion D to the part B. The central portion D, which forms the distance-piece, is severed from the remaining portions of the cylinder by suitable means, such as a fine circular saw, to form narrow ports H extending into the annular 'space E. The inner lips of the ports H are rounded off to prevent damage to the piston packing. The part B may be separate from, and bolted to flanges formed on, the cylinder. In this case, instead of complete circumferential ports, segmental ports are cut through the cylinder, leaving buttress-like parts between them, or complete circumferential ports may be cut and external buttresses formed on the cylinder to connect the central portion to the two ends of the cylinder. Instead of the segmental ports, a ring of holes, countersunk on their inner edges, may be drilled through the cylinder at each end of the central portion D.

Title: Improved Methods of Varying the Speed and Power-factor of Asynchronous Motors.
Filed: 1907-09-24
Abstract: 21,225. Ateliers Thomson - Houston (Anciens •tablissements Postel- Vinay). Sept. 25, 1906, [date applied for under Patents Act, 1901]. Void. [Published under Patents &c. Act, 1907.] Motors, controlling.-The speed of an asynchronous motor is controlled by connecting it in cascade with an alternating current commutator motor the speed of which may be varied by any of the known methods, instead of in series with an auxiliary asynchronous motor the speed of which is varied by changing the number of poles as described in Specification No. 25,979, A.D. 1906. In Specification No. 25,979 referred to, the speed of the main motor may be varied by varying the frequency of the currents supplied to the stator of the auxiliary motor from the rotor of the main motor. For this purpose the rotor current is conveyed to a commutator upon the stator of the auxiliary motor and carrying revolving brushes, the speed of which may be varied. The commutator may be arranged upon the rotor, in which case the auxiliary motor becomes a commutator motor and may be either a series motor, a shunt motor, or a repulsion motor. By shunt transformers and other known means of controlling the speed of the commutator motor the speed of the group may be modified and the power-factor of the combination may be improved by adjusting the brushes upon the commutator motor.

Title: Improvements in Variable Speed Gear for Bicycles and the like.
Inventor: COPE ALFRED WILLIAM
Filed: 1908-02-26
Granted: 1908-11-12
Abstract: 4302. Cope, A. W. Feb. 26. Driving-mechanism.-In epicyclic variable-speed gearing, suitable for cycles &c., of the class described in Specifications No. 15,638, A.D. 1901, and No. 1912, A.D. 1904, i.e., in which a planet-carrier and internally-toothed ring coupled together are movable laterally and adapted to be clutched in turn to the driving and driven members, double planet-pinions or pairs of single planet-pinions are used, so that five gear-ratios, in all, are produced. The parts c, c<1>, Fig. 1, of the double planet-pinions supported in a cage C mesh respectively with sunpinions E, F loose and slidable with the cage C on a fixed axle H. The planet spindles have ends c<6> projecting from cage C on one side adapted to engage notches a in a driving - sleeve A. The internally-toothed ring M, which is carried laterally with the cage C, meshes with the pinion c<1> and is connected to two sets of ratchet pawls, one set m engaging teeth d on a driven hub, and the other set engaging teeth a<1> on the sleeve A. Pawls d' on the hub engage when required with teeth c<3> on the cage C. The sliding parts, which are operated by a rod x inside the axle H, are shown in position for the first or highest speed. The pinion F is held against rotation by teeth h<1> on the axle H, the sleeve A engages the spindle-ends c<6>, and the ring M drives the hub through the pawls m. For the second speed the parts are moved to the left antil the pinion F is released and the pinion E is engaged and held against rotation by fixed teeth h. Further movement to the left disengages the spindle-ends c<6>, and a direct drive is obtained through the two sets of pawls connected to the ring M. At the next step the pawls m become disengaged, the pawls d' come into engagement, and the pinion E remains in engagement with the the teeth h. The ring M is driven from the teeth a' on the sleeve A and the cage C drives the hub. The slowest speed is effected when the pinion E slides clear of the teeth h and the pinion F slides into engagement therewith. In a modification shown in Fig. 2, there are separate planet-pinions c', c<5> which mesh with internally-toothed rings m<1>, m<2> secured together, the action being very similar. According to the Provisional Specification, during the direct drive the power may be transmitted through the planet cage or through both the cage and the internally-toothed ring, in which case the sun-pinions must be free to rotate.

Granted: 1909-09-09
Abstract: 25,699. Denny, A., and Edgecombe, F. T. Nov. 28. Dynamometers.-A damping-device is fitted between one of the relatively-moving members of a torsiometer and the indicating or recording apparatus, in order to prevent violent fluctuations in the torque transmitted from endangering the apparatus. The device may be applied to torsiometers of the type described in Specification No. 3045, A.D. 1907, in which the torque is measured by means of the relative movement between the two sections of a parallel countershaft geared to the shaft under test, or to those in which the relative movement between the adjacent ends of sleeves, attached to sections of the shaft some distance apart, is measured. The invention is shown as applied to an instrument of the latter type. The quadrant G, actuating the multiplying- gear F mounted upon an arm D at the inner end of the sleeve B is, instead of being rigidly mounted, carried by two springs H fixed to brackets upon an arm E at the adjacent end of the other sleeve A. Under abnormal stress the springs H yield. When the torsiometer is used in connexion with shafts not subjected to a fluctuating torsion, such as the shafts of turbines and electric motors, the quadrant may be rigidly connected to the arm E by means of a block fitting between the springs H and secured to the arm.

Alarms, burglar and like.-In a burglar or firealarm installation for safes or strong-rooms in which a partial vacuum is formed within the safe &c., so that on the occurrence of a fire or a burglarious attempt upon the safe, or on the normal opening of its door, a vacuum-indicating manometer d in the safe opens the circuit of a relay e controlling an alarm bell h, the alarm is set by exhausting the safe through the valve c until a bell i arranged near the safe ceases ringing, which occurs when the manometer d closes a contact in the circuit of the relay e. The switch j is then opened and the switch k closed, bringing the bell h under the control of the relay e, so that, when the air pressure in the safe rises from any cause, the bell h rings. A tight joint between the door and the body of the safe is obtained by mounting the door l upon a frame o, which carries a shaft q having at each end an eccentric engaging a hookshaped part t, t<1> fixed to the wall of the safe. When the door is closed, the shaft q is rocked by the handle r, the eccentrics forcing the door against the rubber strips u. In order to prevent the circuit of the relay e from being kept closed by tampering with the cable, sets of blind wires y, z, having their ends inside the safe insulated, are connected to the bell circuits as shown in Fig. 1, so that any tampering with the cable results in the ringing of the bell h.
