Title: Improved Means for Automatically Regulating Air and like Compressors.
Inventor: NEWTON PHILIP ARTHUR
Filed: 1900-12-24
Granted: 1901-02-16
Abstract: 23,560. Newton, P. A., [George F. Blake Manufacturing Co.]. Dec. 24. Compressing.-To relieve air and like compressors of work when the pressure in the reservoir reaches a certain limit, the discharge valves are held open at both ends of the cylinders automatically, so that the air circulates freely between the two ends. The invention is described in connection with a two-stage air-compressor operated by a compound direct-acting steam engine, which is also throttled by the pressure in the air reservoir. Fig. 3 shows a high-pressure cylinder with a delivery valve a and discharge pipe K. The space above the valve is normally placed in connection with the high-pressure reservoir through a pipe 17, Fig. 4, axial passage 2 in the piston valve b, c, and pipe 19. When the maximum pressure in the reservoir is reached, it lifts the valve b against the pressure of the weight w, and the valve b in turn lifts the valve d, which puts the pipe 19 into communication with the pipe 22 leading to the suction pipe or the atmosphere. The pressure above the valve a is thus reduced, and the valve is held open by the pressure in the cylinder and port K. The lowpressure cylinder valve is similarly operated by a valve e, Fig. 5, which is normally held down by the pressure in a branch 23 of the pipe 19, thus permitting the pressure in the reservoir between the two cylinders to act on the low-pressure delivery valves through the pipe 24, passage 6, and pipe 26. When the pipes 19 and 23 are opened to the suction pipe, the valve e rises and puts the pipe 26 into communication with a pipe 28 leading to the suction pipe, thus allowing the deliver valve to be held open. By means of the valves shown in Figs. 9 and 10, the low-pressure cylinder is relieved just before the high-pressure one by the valve g, which is controlled by the valve f. The valve f is raised with the weight by the pressure in the high-pressure reservoir, and cuts off from this pressure the space 39 above the valve g, and opens it to the suction pipe through passages 6, 4, 21, 22. As soon as this occurs, the valve g is raised by the pressure in the intermediate reservoir, and successively puts the ports 18 and 25 into communication with the suction pipe through passages 6, 7, 21, 22. The port 25 leads to the low-pressure discharge valve, and is normally open to the pipe 24 through the passages 9, and the port 18 leads to the high-pressure discharge valve and is normally open to high pressure through the passages 17, 2, 38 and valve 40. The valves f, g may be simplified for a single-stage compressor, as shown in Fig. 13.

Title: Improvements in or connected with the Manufacture of Steel and in Alloys Containing Steel or to be used therewith.
Inventor: LORRAIN JAMES GRIEVE
Filed: 1901-01-16
Granted: 1902-01-16
Abstract: 1099. Lorrain, J. G., [Thomson, G.]. Jan. 16. Casting.-An alloy which may be mixed with, or united with, steel, may be produced by using 65 parts of copper and 35 parts of nickel. In producing the steel, the molten alloy and steel may be poured in simultaneously at first, and then the steel only. The steel thus produced may be employed for sheathing purposes, or for armour plates. When Bessemer steel is used in the process, the metal is run, in a molten state, into water so as to form shot-like pieces which are re-melted with carbon and sand. When Siemens-Martin or open-hearth steel is used, the metal is covered with charcoal before being run from the furnace, and poled by means of wood or carbon blocks. Bolts or rivets to be used with the plates are preferably made in a similar manner. The steel prepared by pouring molten steel into water, and then remelting, may be employed by tool steel and tool makers, and the alloys, contained by the process above described, may be used in making cooking utensils and the like. Alloys of nickel and steel may be manufactured in a similar manner, the steel and nickel being poured in simultaneously, at first, and then the steel only.

Title: Improvements in and relating to Pasting Device for Cigarette Machines.
Inventor: BRUL NAPOLEON DU
Filed: 1901-07-18
Granted: 1901-09-28
Abstract: 14,633. Du Brul, N. July 18. Cigarette - m a k i n g machines.-Relates to the pasting-apparatus, and consists mainly of means for releasing the piston from the driving-mechanism if the paste does not escape sufficiently to prevent excessive pressure. The screwed stem 4 of the piston 3 works in a nut 5, and is actuated through a clntch 7, 8 by a worm 17 and worm-wheel 6. The worm-wheel carries a clutch piece 7, which engages a sliding piece 8 connected by a key and slot with the screw 4 and forced downwards by a spring 11 bearing on an adjustable collar 12. The piece 8 rests on a sleeve 14, bearing on the nut 5, which is thus held down by the pressure of the spring. Under excessive pressure the nut 5 rises on the screw, and lifts the piece 8, thus disconnecting the screw 4 from the wheel 6. To allow the removal of the piston 3, the nut 5 is divided, the parts being separable laterally by turning a disc 20 by a handle 25. The disc carries vertical pins which engage inclined slots in the parts of the nut.

Abstract: 21,649. Flemming, C. E. Oct. 4. Machines for making.- Relates to the machine described in Specification No. 12.511, A.D. 1901, for drilling and filling brush backs, and has for its object to prevent irregularities in the working due to the ratchet pawl failing to engage with the teeth spaces of the templet disc 7, Figs. 1 and 2, particularly when small brushes are being made and the distance between the teeth is very small. Fig. 1 shows a side view, and Fig. 2 a part perspective view. According to this invention, the ratchet pawl 24, its spring 25, and double-ended lever 22 are all mounted on the movable frame C, which carries the mechanism requisite for the shifting of the slides carrying the brush backs, so that the pawl 24 remains in gear with the disc 7 while the frame C is being moved. The lever 22 has connected to it a lever b pivoted on the frame C, while its hook end d is turned under a blade spring f on the fixed framing e, which serves as a guide to the frame C. When the frame C moves to the right, the end d of the lever b first abuts against the fixed framing e, and then, on a further movement of the frame C, the lever b is raised together with the spring f, and thus the lever 22 is turned and the pawl 24 raised, and, when the frame C moves to the left-hand, the end d of the lever b sinks, and the pawl is lowered The spring g ensures the return of the lever b. The part h of the framing e against which the lever b abuts is made movable, so that it can be adjusted to vary the motion of the lever b when a disc 7 with teeth of a different pitch is in use.

In order that the coupling-head may act also as a buffer, it is formed in one with boxshaped flanges i having flat buffing-faces i<1>, or it is fitted with a similar buffing-head i, Fig. 10, made in one with a square sleeve j which surrounds the shank a of the coupling-head and abuts against a buffing-spring o. The shank a also passes through a sleeve t surrounded by a draw spring t<1>, and a fixed abutment s is placed between the buffing and draw springs. The hole in this abutment is rounded, and the hole in the end beam is elongated, in order to allow the couplings and buffers to oscillate and remain in close engagement when passing round curves. Springs x, x on a transverse bar y return the couplings to their central position. The coupling-head is fitted with a hand-lever d, Fig. 9, which, by its weight, causes the engagement of the couplings and which serves for disengaging them. The lever works in a guide f, and can be secured by a pin put through holes in the guide. If the buffer head is made in one with the coupling-books, the lever is loosely engaged with the shank of the coupling, as shown in Fig. 12, and its boss e, Fig. 4, is fitted into a sliding plate p working in a guide q and is retained by a lug entering a segmental recess in the plate p. If the buffer head is in a separate piece, the boss e, Fig. 11, of the lever d is engaged with the shank by a key k and fits into a recess in the buffer head.
