Title: Improvements in and relating to cam mechanism
IPC: F01L1/06
Filed: 1922-06-14
Abstract: 203,087. Entezam, A. June 14, 1922. C a m mechanism for actuating valve - operating rods in internal-combustion engines &c., of the kind in which an endless cam groove formed in the face of a disc comprises two opposite spirals intersecting and leading into one another, a pivoted gate being provided at the intersections to direct the travel of the actuated member. The pivoted gate is normally held by a spring across the trail end of the inner curve of the spirals, being turned aside and across the leading end of the inner curve by the actuated member as it leaves the inner groove. The spirals may comprise two or more coils with a corresponding number of intersections to each of which a pivoted gate would be provided. In the form shown, the gate 8 pivoted at 9 is normally held by a spring 10 across the trail end of the inner curve 3 against a stop 11, rotation being in the direction of the arrow, thus guiding the spring- pressed valve rod 6 towards the centre of the disc 1. On traversing the inner curve, the roller 5 turns the gate 8 aside so that it lies against the stop 12 and closes the leading end of the inner curve to direct the rod into the outer curve 4 for its outward stroke.

Abstract: 641,774. Agricultural implements. CUTHBERTSON, J. A. June 21, 1948, Nos. 16583 and 29319. [Class 6(i)] An agricultural implement for treating grassland comprises a plurality of laterally-spaced arms 10 pivoted on a common transverse axle 9 for independent rocking movement, each arm having, at each end, a rotatable straked or spiked roller 13. The transverse axle is carried by a main frame, 2, 3, which is towed by a tractor and which also carries a transport device comprising land wheels 19 which can be lowered to support the frame and raise the rollers 13. The land wheels are mounted on triangular structures 16 pivoted at 17 to the main frame and retained in an inoperative position by a levercontrolled pawl 21 and ratchet 20. The wheeled structures 16 may be lowered by pulleys 27, 30 and tackle 28. In a modification the main frame includes a ballast container, and the transport wheels are mounted on axles adjustable on vertical pillars. The tools may be triangular, spade-like, or may comprise blades arranged in chevron-pattern around the circumferences of the rollers.

Title: Improvements in or relating to umbrellas, sunshades and the like

Filed: 1939-06-06
Abstract: 523,244. Umbrellas. CORNIC, E. June, 6, 1939, No. 16606. Convention date, March 8, 1939. [Class 134] A device for retaining the ribs of an umbrella closed comprises a rubber ring which rests, in its inoperative position, in a groove formed in fixed relationship to the stick and handle closely adjacent to the ends of the ribs and which, by finger operation, can be rolled out of the groove over the rib ends, that flange of the groove which is remote from the rib ends having a greater diameter than the other flange so as to form a retaining abutment 'for the ring when it is rolled into the groove. As shown in Fig. 1, the groove is formed in a ring 4 on the spigot between the handle 2 and stick 1. The ring 6 is of such an internal diameter as to be retained by its resilience on the bottom of the groove, from which it is prevented from escaping upwards towards the handle by the larger flange 11 of the groove member. When slid out of the groove, as at 10, it grips the ribs between their ends and eyes 8 without touching the fabric of the umbrella. The ring may, alternatively, be made of two or more segments held in place, for example, by a binding ring or wire. It may also carry an eyelet or the like to receive a carrying loop. In another arrangement, . the groove is formed, not in a separate ring, but directly in the outwardly flared upper extremity of the stick where it is attached to the handle by the joint known as an "invisible" joint.

Abstract: 1336185 Railway brake-operating mechanism CARDWELL WESTINGHOUSE CO 24 May 1971 [6 July 1970] 16680/71 Heading F2E A chain 49 attached to a railway-wagon brake (not illustrated) is wound up on a drum 30 by a hand-wheel 68 through gearing 62, 276 and 278 and teeth 220 on the drum; the direction of rotation of hand wheel and drum being clockwise. The second link 243 of the chain is accommodated in a recess 237 of the drum hub and thereafter successive links are accommodated alternately in recess 232 and on surfaces 236, 238 of the drum hub until the drum has been rotated through one revolution plus 30 degrees: after which no more chain can be wound on. When the brake is released, a stop arm 248 loosely mounted by its collar 246 on the drum hub is not affected by drum rotation until a lug portion 250 on the drum hub makes contact with it, whereupon it is moved into contact with surface 260 of a stop block 254 fixed to the back plate 18. Further "unwinding" movement of the hub is thereby prevented. The embodiment of Fig. 3 (not reproduced) may be used with the brake operating mechanism of Specification 1,176,761.

Title: Improvements in apparatus for cracking hydrocarbons
IPC: C10G9/40
Filed: 1924-07-11
Abstract: 230,339. Niece, F. G. July 11, 1924. Hydrocarbons, cracking.-In cracking hydrocarbons by passing oil or vapours together with uncondensed gases from the process through a body of molten metal, the oil or vapours are passed downwards through a central feed pipe which is surrounded by a pipe for the supply of uncondensed gases so as to prevent overheating and deposition of carbon, and the upperends of the feed pipes are movable to allow for expansion and contraction. Oil or vapours are forced by a pump 41 down a central pipe 33 discharging through a conical outlet 34 into the base of a furnace-heated vessel 17 containing molten material. Vapours pass from the upper end of the vessel to a condenser 27 and uncondensed gases are withdrawn from the condensate receiver 56 by a pump 53 and are passed into the molten material through a pipe 48 surrounding the pipe 33. The upper ends of the pipes 33, 48 are fitted with cylindrical casings 30, 45 slidable on the feed inlets. Projections 62, 63 on the conical outlet 34 and the base of the vessel 17 prevent closure of the pipes 33, 48. Deflectors 66 are attached to. the outside of the pipe 48.

The nose of the shell rests in a tapered collar 34, Fig. 5, adjusted by a cap 32, screwed on the end of the sleeve 13 or some other part, and the position of the shell is gauged and indicated by a lever 39 moving over an indicator 42. In a modification, the nose of the shell rests on a stop-plate secured to the cap 32. The hole in the body of the shell is bored by a drill 25, carrying a countersinking cutter 27 of slightly less diameter than the bore of the body of the shell. The parts are positioned so that, when the drill' has reached the required depth, the face of the cutter 27 is flush with the shoulder 28. The remainder of the explosive in the enlargement 29 then falls out or can be withdrawn easily. The borings fall into a receptacle 16, Fig. 3, and are exhausted through a pipe 17. The drill is rotated by a belt on a pulley 19 and is raised to the required height, regulated by an adjustable stop 22 striking the spindle-bearing 2, by a lever 3.
