Title: Improvements in and relating to Telescopic Compound Engines.
Inventor: SCHNEIDER WILLIAM
Filed: 1901-04-30
Granted: 1901-09-21
Abstract: 8913. Schneider, W. April 30. Central-valve engines; compound engines.-Comprises improvements in " telescopic compound locomobile engines, applicable also to stationary and marine engines, in which a highpressure cylinder reciprocates on a fixed piston or abutment, and carries a piston reciprocating in the low-pressure cylinder, which is stationary, the high-pressure cylinder driving the crank shaft by a connecting-rod. Fig.1 is an elevation of a twincompound locomobile engine embodying the invention, Fig. 2 an underside view thereof, and Fig. 3 a vertical section through one of the engines. The head c of the low-pressure cylinders a are chambered as shown at d, and have secured to them, or are formed integral with, tubular extensions e, to which are secured the stationary piston abutments f. The piston abutments are chambered as shown at g. The chambers d in the cylinder heads are closed by a cap plate h common to both cylinders, and made, as shown in Fig. 2, with a partitioned casing i with two openings or branches 1, 2. The branch 1 is the steam branch, and communicates with the tubular extension e, and the branch 2 is the exhaust branch and communicates with the chamber 7. The low-pressure cylinders are formed with extensions m carrying the bearings for the crank shaft q, and have bifurcated extensions r for the usual brace for keeping the driving-chain taut. The engine is itself made to supply compressed air for forcing liquid fuel to the steam-generator heater. In the head 8 of the low-pressure cylinder is formed an annular air chamber o, and the tubular extension n of the high-pressure cylinder is closed to form an air chamber p. The latter has parts 10 leading to a reduced portion of the extension n forming an annular passage through which, during the in-stroke of the highpressure cylinder b, air is passed from the chamber p to the chamber o. Between the extensions m of the low-pressure cylinder are two pipes u, v communicating with the chamber o and connected to opposite branches of a four-way union or coupling w, which is furnished with a relief pipe x and a pipe ,y capable of being connected to the fuel reservoir. Another arrangement for relieving the cylinders of air pressure and utilizing a portion of the air in the fuel reservoir is shown in Fig. 15. A pumping-chamber 17 is formed between the extension m of the low-pressure cylinder and the extension n of the high-pressure cylinder, and the air is delivered through pipes 21, 22, 26 furnished with suitable inlet and outlet valves. The tubular distributing-valves 30 of the engine have ports 31, 32, 33. and are worked by spindles 40 passing through the back ends of the cylinders and connected to the reversing-linkage shown, whereby the throw of the valve may be varied and the working of the engine changed from compound to semi-compound in an equivalent manner to that described in Specification No. 7841, A.D. 1901.
Patent GB-190115670-A (GB)
Title: Improvements in and relating to the Firing Mechanism of Breech Loading Ordnance.
Inventor: DAWSON ARTHUR TREVOR
Filed: 1901-08-02
Granted: 1902-07-17
Abstract: 15,670. Dawson, A. T., and Buckham, G. T, Aug. 2. Ordnance breech mechanism.-Relates to improvements upon the invention described in Specification No. 10,606, A.D. 1896. Fig. 1 shows an end elevation with the hammer down, Fig. 4 a horizontal section with the hammer cocked, and Fig. 5 a separate view of the trigger. The hammer J is pivoted at i to the slide I, upon which is also mounted the cocking-lever K, and the mainspring for operating the arm j of the hammer. The slide I is mounted upon the breechscrew carrier C, and, when the breech-operating lever G is pulled outward to unlock the breechscrew, it carries the cocking-lever K with it, and this carries the hammer J into cocked position, and at the same time turns on its fulcrum k and moves the slide I to the right, thus exposing the bead of the primer case E. The opening movement also causes the primer-extractor F to be turned on its pivot d<x> to eject the empty case. The gun is discharged by pulling the trigger H to the left. In the modification shown in horizontal seetion in Fig. 7, the hammer L' is down. This hammer slides axially with the gun, and is cocked by hand. It is mounted in a sleeve L<3> projecting from a frame K<1> which has a vertically-sliding movement on the gun. The trigger H normally presses back the hammer, as shown, so that its point is away from the primer. As the hammer is pulled back, the surface l<3> presses back the trigger until it drops into cocked position in front of the surface l<1>. In modifications of the mechanism shown in Fig. 7, (1) the trigger H is pivoted instead of being made to slide longitudinally, and (2) the mechanism is adapted for use with fixed ammunition, and the hammer is then withdrawn clear of the cartridge base by importing a rotary movement to it as the hand-lever is swung outwards, provision being also made for locking the trigger in its cocked position until the breech-screw is locked, and for permitting the use of a lanyard that shall not swing outward with the breech-screw.
