Title: Improvements in Locks.
Inventor: BRETT WILLIAM
Filed: 1898-01-05
Granted: 1898-11-05
Abstract: 330. Brett, W. Jan. 5. Locks, key; keys.-The lock a is provided with a spring bolt d, which is operated indirectly by the key shown in Fig. 9, through the pivoted plate f. This plate is pivoted on the key pintle g, and engages the stud h on the bolt d to retract the latter. The plate f is normally locked by pins k, which are carried by blade springs l and engage in corresponding holes i in the plate. The back of the cover plate b, Fig. 8, is provided with a stop n, which is formed, as shown, with wards corresponding to the wards o on the key. The key is inserted in the keyhole m and turned until it engages the stop n. It is then pressed in until its projections j enter the holes i and disengage the pins k from the plate f, after which a further rotation of the key effects the rotation of the plate f to retract the bolt. The bolt is protected from direct operation, such as by picking, by the partition s and a longitudinal guard-plate, the plate f being rabbeted at u so that it lies flush with the guard-plate. The ends of the pins k also normally lie flush with the surface of the plate f, so as to give no indication of their position. A stop bar q is preferably provided, to prevent the operation of the lock by an improper key having projections j of greater length than the thickness of the plate f. The sliding catch v is adapted to engage the tail of the bolt, to hold the latter when retracted, when desired.

Title: Improvements in or relating to Weighing or Computing Scales.
Inventor: DUNCAN JAMES EUGENE
Filed: 1898-01-18
Granted: 1898-07-09
Abstract: 1410. Duncan, J. E. Jan. 18. Value-indicating apparatus.-An apparatus for weighing and computing the value of a weighed article at different rates per unit of weight is shown in Figs. 3 and 5, and consists of a poise 20 mounted upon a cylinder 7 with a coarse-threaded screw 8, so that the movement of the poise causes its supporting-cylinder to turn and thereby rotate the computing-cylinders 14, 15 by a train of wheels 11, 12, 13. The computing-cylinders are so arranged that the weight and value can be read off directly, and in the present instance the pointer 16 indicates a weight of two pounds while the value for any given rate, say seven pence per pound, is indicated by the numeral opposite the figure seven on the weight scale ; the value for any other rate can be read off by inspection. The poise is formed of two separable parts, one only of which need be used for weighing and thereby giving a different and lower value to the figures on the weight scale. By the arrangement of double computing-cylinders greater range of prices is obtained with a given length than could be obtained with one cylinder only.

Granted: 1898-10-08
Abstract: 8004. Friedlaender, M. M. April 4. Annular-chamber type.- Cam mechanism for quickly and noiselessly actuating the obturator or slide valve, and spring vane or abutment packing for preventing loss of steam. The nave b works steam-tight in recesses in the cylinder covers d, in which grooves e are also formed to guide the ends of the tapered obturator or slide valve f. The latter is connected by parts i, g, and k to a lever l, pivoted to the standards n. An enlargement o on the lever l rides on the curved surface p of the cam q, and the surfaces o, p are steadily maintained in contact by a roller r<2> carried from a spring mount on the lever l. The circular portion of the cam q keeps the obturator closed so long as the steam is operating, while the irregular portion of the cam surface quickly raises the obturator for the passage of the vane or abutment c, and then lowers it. In the construction shown in Fig. 2, the cam mechanism shown on the left-hand side of the Figure is, in practice, duplicated on the right-hand side, but a cam mechanism arranged on one side only may be used. A curved frame may be substituted for the parts g, k, and in high-speed motors the part o is replaced by a spring sleeve provided with rollers. A steam-tight joint between the casing and the vane or abutment c is obtained by forming the latter with parts movable in two directions by springs.

Granted: 1899-08-19
Abstract: 7008. Maassen, W., and Wirtz, W. April 1. Brakes for flywheels or o t h e r rotatory bodies. Mounted near the wheel is a compound eccentric a, g, the outer ring a of which is normally held out of contact with it by the engagement of a projection e with the armature i of an electromagnet c. When a contact, say at b, is pressed, the armature is raised and liberates the ring, which, under the influence of a spring f, is turned round into contact with the wheel; the ring is then carried on by friction, exerting a gradually increasing pressure and involving the inner eccentric g in its movement, until the wheel is brought to rest. Preferably two such devices are employed, one at each side of the wheel, and a weight may be used instead of the spring f; the electromagnet may be replaced by any other actuating-device.

Title: Improvements in Cranes and Hoisting Apparatus.
Inventor: WILLIAMS ARTHUR EDWARD
Filed: 1900-04-12
Granted: 1901-03-30
Abstract: 6920. Williams, A. E. April 12. Cranes.-The carriage a carrying the jib g runs along rails b on the side of a jetty. The lifting- rope passes from the winding-drum n around a pulley i at the end of the jib back to a travelling carriagej, around a pulley on which it passes to the usual skip p. The pulley l is mounted in a frame free to rotate about an axis parallel to the jib. Upon the axle of the drum n is also mounted a second drum 19, from which a rope 20 passes over pulleys at the top of the crane to a balance weight 22. A rope r attached to the inner end of the car j passes to a drum S, from which also a second rope passes to a balance weight z, which thus in the absence of a load tends to move the carriage j inwards along the jib. A load, however, overcomes the weight z, and forces the carriage j to the outer end of the jib, where it may be secured by a catch. For unloading a ship into a barge, therefore, as shown, the carriage runs automatically in and out. The jib is balanced by a weight on an arm 2 connected to the jib by a rope 4, in such a way that the movement of the weight varies with the movement of the jib. The pulley i at the end of the jib may have sliding bearings, and be fitted with a ram working in a cylinder in communication with a pressure gauge so that the weight of the load may be estimated.

Abstract: 9820. Heys, W. E., [Schaeffer & Budenburg]. May 29. Lubricators. - Lubricants are supplied under pressure, to parts requiring to be lubricated, by means of a pump. In the simplest form, a cylinder is formed with two bores c and r, and a ram k, which fits the smaller bore, reciprocated therein. The bottom of the part c communicates with a pipe l leading to the part to be lubricated by a passage or passages controlled by a non - return valve or valves v. The part r communicates with the air by a passage t, and with a cup, to which lubricant is supplied through a pipe h so as to form a visible feed, by a passage s. When the ram is in the raised position, the lubricant flows into the part c, and on the descent of the ram is forced past the valve v and through the pipe l. On the ascent of the ram, a vacuum is formed in the part c, and the oil that has collected in the part r immediately flows into the lower part when the ram is clear of the same. In a modification, a number of cylinders, each fitted with supply and delivery devices, are arranged over each other, and a single rod, suitably stepped to form a number of rams, is employed to operate within the various cylinders.
