Patent GB-189714904-A (GB)
Title: An Improvement in Ink Distributing Apparatus for Printing Machines.
Inventor: YATES WILLIAM BURTON
Filed: 1897-06-19
Granted: 1897-07-31
Abstract: 14,904. Yates, W. B. June 19. Inking-apparatus for cylinder machines. Relates to means for driving the distributing-rollers, and for varying the angle at which they lie across the machine. Two pulleys G, M are mounted on the frame of the printing-machine, and a belt H, moved to and fro by the reciprocating table, passes round them. On the shaft of the pulley G is a gearwheel F gearing with two wheels E which drive the rollers A. The rollers A drive the distributing- rollers K by frictional contact, but do not come into contact with the ink table. The end of each roller A geared to the wheel E is journalled in a bearing mounted on a vertical pivot b, and the teeth of the gear-wheels are so cut that the angle of the rollers A, K may be varied.

Title: Improvements in or relating to the Driving Appliances of Cycles.
Inventor: SIMPSON WILLIAM SPEIRS
Filed: 1897-07-31
Granted: 1897-10-23
Abstract: 18,024. Simpson, W. S. July 31. Chain gearing. - The crank G has a disc or shoulder K, Fig. 2, to which is secured a disc or framework E'. Bolted to E<1> are four pins P each of which carries a star-wheel H engaging with the driving-chain I. Pinions D are secured to shoulders on the wheels H, and engage with a stationary wheel B. The latter has a collar which screws into the bottom bracket, and is also formed with a flange Q which serves as a cup for the crank-axle bearings. Two rings M having shoulders N and running on rollers L, the latter being carried, as shown in Fig. 2, by ball bearings on pins secured to the disc E', rotate with the chain and prevent it from sagging between the cog-wheels H. The pins P are connected at the inner ends by the framework E. By this arrangement the crank causes the wheels H and D to revolve round the stationary wheel B, thereby causing them to rotate on their axles and drive the chain I.

Title: Improved Safety-guard for Steam Tramcars and other Carriages Propelled by Mechanical Power.
Inventor: SCHOTT GUSTAVUS ADOLPHUS JOHN
Filed: 1897-10-30
Granted: 1898-10-29
Abstract: 25,168. Schott, G. A. J. Oct. 30. Tramway engines; motor road vehicles.-Consists of a safety guard which on meeting with an obstruction is depressed so that a broom-likeextension B comes into close contact with the ground. It is held in this position until released, so that the object in front cannot pass under it, but is either swept aside or deposited on the platform of the guard. The movement of the guard may be utilized for releasing the catch of an alarm, or for effecting an automatic application of the brakes. At a higher level, and in front of the guard and broom, a net S may be provided. The lowering of the guard is brought about by a trigger-action operated by pressure against the net supports F or against certain cords E, the necessary actuating power being furnished by a constantly-rotating shaft H.

Patent GB-189824107-A (GB)
Title: Improvements in Mechanical Door Checks.
Inventor: MILLS BENJAMIN JOSEPH BARNARD
Filed: 1898-11-15
Granted: 1898-12-23
Abstract: 24,107. Mills, B. J. B., [Hanington, C. F.]. Nov. 15. Door checks.-Relates to devices adapted to arrest the closing of the door elastically immediately before the door reaches a completely-closed position, after which the door rebounds and closes easity wituout shock. In one form of the device, Figs. 2 and 3, the end of a lever 10, pivoted at 12 on the leaf 2 of the hinge to which the door is fixed, works in a groove 5 on the fixed part of the hinge. As the door closes, the end of this lever 10 comes against a shoulder 6, and checks the movement of the door by pressing against a flat spring 14 attached to the door. The impact against the shoulder 6 disengages a detent lever 18 from the spring 14, and allows the end of the lever 10 to rise into the groove 8, along which it moves till the door is closed. The detent 18 is reset by striking against the end 24 of a screwed pin, which may be withdrawn when the checking movement is to be dispensed with. Modifications are described in which detent levers, not pivoted on the lever 10, are used to keep the lever down until it strikes the shoulder 6.

Granted: 1902-04-03
Abstract: 7659. Musker, A. April 15. Moulding cement, concrete, &c.-In a press for moulding cement, concrete, &c. into slabs or other articles, a pump a, driven by belt gearing, a motor, or other means, is employed to pump water from a reservoir to the cylinder e. A relief valve i and an auxiliary relief valve k<1> are provided on the pump, or on the pipes, to release the water when the pressure rises too high, pipes being arranged to conduct the water back to the reservoir. The moulds or slab frames h are mounted on the table, through which the ram of the press passes. The upper part of the mould is hinged to a base portion h<3>. The ram, on being raised by the water pumped into the cylinder e, forces the material in the mould against a head h<1>. A wheel m is employed to operate a valve i<2> for controlling the water supply. A plunger l, operated by hand or foot mechanism l<2>, passes through an extension of the table, and is employed to eject the moulded articles from the mould. A tamping or ramming mechanism, supported from the arms of counterbalanced levers u, u<1>, is arranged on the apparatus. The mechanism consists of a number of stamps n<1> operated from the shaft c through belts o, o<1>, o<2> and pulleys. The device is raised or lowered by means of handles p<1>. When the tamper is ra sed, a pin q on the rammer engages a lever q<1>, which operates a clutch r and throws the stamps out of gear. Upon lowering the tamper, a spring s<1> operates the clutch to put the stamps into gear.
