Title: Improvements in Valve Gear for Internal Combustion Engines.
Inventor: LEWIS DAVID
Filed: 1908-08-01
Granted: 1909-06-10
Abstract: 16,356. Lewis, D., and Briggs, M. Aug. 1. [Patent of Addition to No. 24,946, A.D. 1907.] Gas and explosive-vapour engines.-In a modification of the valve-gear and reversing arrangements described in Specifications No. 24,946, A.D. 1907, and Nos. 8638 and 8940, A.D. 1908, the half-compression cams are dispensed with, a single handlever being also provided to control the various adjustments when starting and reversing. The inlet and exhaust valves V, W are actuated by ratchet-driven cams carried in a framework as described in Specification No. 24,946, A.D. 1907. When admitting compressed fluid at starting, the inlet valve W remains closed but the exhaust valve is opened during each instroke by the downward movement of arms g, the rollers k of which are held in recesses in the temporarily-stationary cam n. The cam is held stationary by reducing the stroke of the pawl s, when adjusting the reversing lever, so that it fails to engage the longer teeth on the ratchet-wheel r. Short teeth, which alternate with the longer ones, are formed on the ratchet-wheel, and with these the pawls engage should the cam, after the throwing over of the reversing-lever to the position A' or A<4>, take up a position in which the rollers k cannot enter their corresponding recesses in the cam n. The supply of compressed fluid to the valve 2 is controlled by a valve the stem D of which is actuated by rollers carried on the handlever B. The valve is opened when the hand-lever is in either. of the starting or reversing positions A<2>, A<4> , a tripping-device (not shown) being provided to disengage the valve roller E from the rollers F, G when the hand-lever moves over to its normal working positions A', A<5> respectively. Before the re-engagement of the rollers F, G, and E can be effected the hand-lever must be returned to its neutral position A<3>. To reduce the opening of the exhaust valve, when starting, additional projections g<1> on the arms g may engage a disk 1 on the end of the valve spindle, supplementary recesses being provided in the cam n to hold the arms farther apart. Some form of frictional resistance, such as a brake, may be used to prevent the inertia of the parts from carrying the cams past their working positions. To reduce the speed of the engine, before reversing, compressed air is admitted to oppose the forward motion of the piston.

Title: Improvements in and relating to Starting Mechanism for Internal Combustion Engines.
Inventor: SNOW ERNEST
Filed: 1908-09-15
Granted: 1908-12-31
Abstract: 19,318. Snow. E. Sept. 15. No Patent granted (Sealing fee not paid). Gas and like engines, starting. Turning-gear for engines, particularly those of motor road vehicles, comprises a crankhandle N which connects with the motor shaft by a suitable clutch and carries a pawl B which moves over the fixed ratchetdisk D on the framework of a vehicle or engine, and is guided by the projecting flange C on the disk. The pawl B comprises a bowed or equivalently-shaped flat spring which slips over the ratchet-teeth during the forward motion of the handle for starting, but forces the starting-handle out of gear with the motor shaft when a premature explosion occurs, owing to its resistance to deformation of shape. The ratchet-disk may be solid instead of annular, and may have teeth of fibre or like material to ensure silent action of the device ; also it may be attached to the framing in various ways instead of by bolts E passing through internal radiating lugs as shown. Various means of attaching the spring pawl to the operating- handle also are described.

Title: Improved Tape Transmitter for Multiplex Telegraph Systems.
Inventor: MURRAY DONALD
Filed: 1908-12-11
Granted: 1909-07-15
Abstract: 26,916. Murray, D. Dec. 11. Telegraphs.-In a perforated-strip transmitter, specially applicable to multiplex systems with distributors, the strip is fed forwards letter-space by letter-space and each space is moved against a group of five needles which control contact strips connected to segments of a distributor, in such a way that a perforation in the strip corresponds to a current of different sign on its segment from an unperforated part. Figs. 1 and 4 represent a plan and elevation of the instrument. The strip 12 is prepared in advance and passes around the star-wheel 6, which is on the same axis as the ratchet-wheel 8. The shuttle 3, mounted on balls 4, 5, is moved a short distance to the left by the armature lever 36 of the electro-magnet 32, and is returned by the spring 38. The movement to the left causes the pawl 16 to rotate the ratchet-wheel 8 one step, and so to feed the strip 12 forwards one letter-space. The movement to the right brings the strip against the ends of the five needles 18, which terminate to the right in the cap 21 opposite the contact-springs 22. The needles that are opposite a perforation are unaffected, but the others are moved to the right and press their springs 22 against the negative terminal 23. The contacts 29 are connected to the distributor segments. The instrument is provided with a stopping-lever which can be operated only when the attraction of the armature 34 moves a stop away from its line of movement. The stopping- lever prevents the reciprocation of the shuttle and operates a switch which connects both posts 23, 24 to the negative pole of the battery. Specifications No. 11,778, A.D. 1899, [Abridgment Class Printing, Letterpress &c.], No. 10,142, A.D. 1900, No. 21,880, A.D. 1901, and No. 3385, A.D. 1904, and No. 21,064, A.D. 1904, [Abridgment Class Printing, Letterpress &c.], are referred to.

Abstract: 266. Bates, H. A. Jan. 5. Sewing-machines; lock-stitching by shuttles. -In a shuttle which comprises a bobbin-case holder and a separable bobbin case and thread bobbin, a volute spring is provided between the bobbin and the bobbin case and in front of the bobbin, which spring acts expansively to separate the parts when the bobbin case is released. The bobbin-case holder a is provided with a central tubular pin a<2>, slotted at one side, having its outer end pivotally connected to a locking-lever b. The inner end of this lever is bevelled so that it is held in either of its two positions by the spring-pressed plunger 4. The bobbin-case c has a central aperture c<1>, through which the pin a<2> passes, and is provided with a volute spring d, the large base convolution 5 of which is held frictionally in the base angle of the bobbin-case. The spring is coiled for compression in the direction of the axis, and normally fills more than half the case. The thread bobbin f, when placed in the case, presses the spring practically flat, and the bobbin and case, when placed on the pin a<2> of the holder, are held in connexion by the turning into the full-line position, Fig. 4, of the lever b. When this lever is turned to the dotted-line position, the spring d immediately causes the partial separation both of the case-holder and the case, and of the case and the bobbin.

Granted: 1910-03-24
Abstract: 8269. Peacock, J. H., and Topliff, F. April 6. Working - fluid supply; movable - abutment type.-Relates to an internal-combustion rotary engine. A driving-vane D is mounted upon a hollow shaft M, within which is a shaft K carrying a vane E, a slot H allowing the vane E a certain amount of movement relative to the vane E. The shafts K, M are connected together by variable-speed gearing. When the vane D passes the inlet A, it travels faster than the vane E, and gas is sucked in. The vane E then accelerates and compresses the entrapped gas. When the charge is opposite the sparking- plug situated in a recess F, it is ignited, the vane D is propelled forwards, and the vane E is held against a ratchet stop S and afterwards follows up the vane D. The spent gas is exhausted through a port C, and the abovedescribed cycle of operations is repeated. The pieces B act as " pressure-directing vanes." Openings G in the ends of the casing allow ingress and egress of air for cooling purposes.

Title: Improvements in Ribbon Reversing Mechanism for Cash Check Tills, Typewriters and the like.
Inventor: GLEDHILL ARTHUR HENRY
IPC: B41J33/40
Filed: 1909-04-08
Granted: 1910-02-24
Abstract: 8467. Gledhill, A. H. April 8. Ink-ribbon mechanism. - Relates to automatic feed reversals of the kind wherein the reversal is initiated by the tension put on the ribbon when one of the spools is emptied. The ribbon passes between two spools 1 journaled in a rocking frame 3 and provided with worm-wheels 5, which are alternately put into gear with right and left handed worms on a shaft 6. The rocking frame 3 is held in position by a pivoted catch 8, which is engaged by a spring 15 and engages the sides of a groove 13 in the frame 3. The ribbon being wound on the spool engages and tilts a tumbler 9, which is pivoted on the stud 4 of the frame 3 and is provided with a spring pin 10 arranged to work over an apex 11. When the full length of the ribbon has been wound, the increased tension causes the driving- worm 6 to lift its worm-wheel 1 out of gear, thereby overcoming the spring catch 8 and rocking the frame 3, and throwing the tumbler 9 over the apex 11. The frame is thus rocked to bring the worm-wheel 5 of the empty spool into mesh with the worm-shaft, and the reversal of the ribbon is effected. The ribbon is secured to the spools by spring clips.
