Title: Improvements in Couplings for Vehicles.
Inventor: WILLIAM S SCHROEDER
Filed: 1907-09-10
Abstract: 20,204. Schroeder, W. S. Sept. 11, 1906, [date applied for under Patents Act, 1901]. Void. [Published under Patents &c. Act, 1907.] Couplings, automatic.-In a coupling of the Janney type, shown in position for coupling, in which the knuckle is locked in the coupled position by a longitudinal bar D operated by a vertical lifting-pin F through which the bar D passes, the knuckle B is formed on its underside with an incline b<3> with which co-operates a corresponding incline f formed on an extension f at the lower end of the lifting-pin F, so that by raising the lifting-pin above the lock-set or uncouplingposition the knuckle may be thrown open. The extension f<1> also serves to retain the pin in lockset position by engagement with a shoulder a' on the draw-head. When the knuckle is opened by pulling the cars apart while the pin F is in lock-set position, the knuckle-tail engages a bevelled portion f Fig. 9, formed on a projection f of the pin, whereby the pin is dislodged from the shoulder a<4> and the locking- bar D falls on the knuckle-tail in position for re-coupling, as shown in Fig. 2. Upward creeping of the lock is prevented by the engagement of a rearward projection f<8> on the pin with the edge a<8> of the draw-head, such engagement being ensured in the case of upward movement of the locking-bar D by the co-operation of inclines d<4>, f<9> on the bar and pin respectively. The locking-bar is formed at its front end with a bevel d<5> in order to facilitate its release from the knuckle-tail, to allow it to fall to the locking position as the knuckle closes. The curved portion f<10> of the pin F serves to throw the lower end of the pin forward during lifting, this operation being performed by a lever G connected to the pin by a clevis g and link g<1>. The rear end of the bar D is pivoted by means of lugs d' engaging notches a<9> so as to allow longitudinal movement between the faces a<10>, a<11> on the draw-bar. The opening in the top of the draw-head is provided with a notch a<19>, Fig. 8, for the passage of the projection f <6> during withdtawal of the pin.

Title: Improvements in Valve Operating Devices for Fluid Compressors.
Inventor: LAKE WILLIAM EDWARD
Filed: 1908-09-08
Granted: 1909-09-08
Abstract: 18,865. Lake, W. E., [Ingersoll Rand Co.]. Sept. 8. Compressing. - Relates to valveoperating devices for fluid-compressors, of the kind described in Specifications No. 22,215, A.D. 1905, and No. 9590, A.D. 1906, and consists in means whereby the inlet valves are opened and closed by fluid pressure distributed by a slide valve within a valve-chest, and the discharge valves are closed by pressure from the chest but are opened by the compressed air in the cylinder, a portion of which is admitted to the valve-operating cylinders by way of ports passed over by the compressor piston. In the double - acting compressor shown, having common inlet and discharge ports 6, 8 respectively, a pair of inlet valves 4 and discharge valves 5, together with their valveoperating cylinders 12,15, are provided at each end of the compressor. Fluid is distributed to both sides of the inlet - valve operating - pistons 11, and to one side of the discharge-valve operating-pistons 14, from a valve chest 33 at the side of the compressing-cylinder through a six-way connexion 20 and pipes 27 . . . 30. The chest 33 is constantly open to a source of fluid pressure by way of a pipe 34, aud is fitted with a slide valve 41 which puts passages 37, 38 connected to the vertical arms 25, 26 of the six-way connexion, Figs. 11 and 12, alternately in communication with the chest 33 and an exhaust pipe 40, which may lead to the compressor inlet 6. By this means the fluid pressure effects the opening and closing of the inlet valves and the closing of the discharge valves. The discharge valves are opened by direct pressure thereon after the resistance to opening due to the weight of the reciprocating parts has been overcome by admitting compressed-air from the cylinder to act on the pistons 14 by way of pipes 31 ending in ports passed over by the compressor piston. The slide valve is tappet-actuated from the compressor piston-rod, the tappet-actuating rod 57 being connected to a rocking lever which is pivoted to a clamp 55 on a stay 56 at the side of the cylinder and slides in a socket of a second clamp on the piston-rod ; the slide valve is thus moved in the same direction as the piston near the end of each stroke. A spring 43 with movable abutments 43<1> at each end returns the slide valve to its mid or inoperative position after displacement in either direction. The valve-chest is provided with a pipe 58 for the attachment of a pressure gauge, and a pipe 59 for lubricating purposes.

Title: Improvements in Speed Indicators.
Filed: 1908-10-19
Granted: 1909-01-28
Abstract: 22,105. Hartmann & Braun Akt.-Ges. Oct. 28, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Speed indicators.-A speed - indicating instrument is provided with two sets of juxtaposed speed indications, one afforded by vibratory tongues and the other by a pointer actuated in any suitable manner. In the arrangement shown in Fig. 2, the frequency scale extends from 500 to 1100, while the indications from zero upwards are given by a pointer actuated by an electric current from a dynamo rotated by the shaft the speed of which is being measured. When the vibratory tongues S are operated electro-magnetically, the electro-magnets I, II, III are arranged as shown, and their poles are curved so that the tongues and consequently the resonance scale may be curvilinearly placed. The circuits of the two indicating-devices may be connected to separate windings of the dynamo armatures ; an adjustable resistance inserted in the pointer circuit enables the indications given by the pointer to be rectified by comparison with the vibration scale. In modified arrangements, the resonance scale is rectilinear and is placed in, above, or below the pointer scale. The resonance scale may be discontinuous and show only certain important speeds. The tongues may be operated by shocks and the pointer by centrifugal means.

Abstract: 18,974. Garthorn, M. Aug. 18. Combined fluidactuated and mechanical gears; oscillating valves; arrangement and disposition of valves.- Relates to constructions of combined fluid-actuated and mechanical valvegears of the type in which the main valve is both oscillated and reciprocated. In the arrangement of the gears shown in Figs. 2 and 3, the valve is arranged transversely to the cylinder, and receives an oscillating motion from the piston - rod through tappets and a lever secured to the valvespindle, which causes auxiliary admission and exhaust ports O, P in the valve to register with auxiliary admission and exhaust ports D, E in the valve-chest. These ports distribute fluid to the ends of the valve-chest to reciprocate the valve. The valve G is provided with main admission ports I, which lead from a transverse slot H in communication with the inlet C and a main exhaust port L. These ports distribute fluid to the cylinder ends through ports J, K when the valve reciprocates. In a modification of the above arrangement, the valve is arranged parallel to the cylinder. The auxiliary ports in this case are controlled by an initial longitudinal motion of the valve, the edges of the valve replacing the ports O. In the application to a compound tandem engine, the valve is arranged transversely and controls the high and low pressure cylinders. The ports are arranged as shown in Figs. 10 and 11, the ports and passages 1', 1<2>, 2<1>, 2 lead to the upper and lower ends of the high - pressure cylinder, and the ports and passages 3<1>, 3, 5<1>, 5 to the ends of the lowpressure cylinder. These ports are controlled by admission and exhaust ports 1, 4, 6, 3<2> in the valve during its oscillating and reciprocating motion. The speed may be regulated by throttling the main or auxiliary exhaust passages or both.
