Title: Improvements in and relating to vehicle differential locks
Inventor: FOXWELL WILLIAM JOHN
IPC: F16H48/30
Filed: 1959-02-25
Abstract: 857,980. Differential gear. FORD MOTOR CO. Ltd. Feb. 25, 1959, No. 6562/59. Class 80(2). To lock a bevel gear differential 21 used in a tractor, a pedal 1 is depressed to turn a shaft 2 carrying a lever 3 and a coacting bell-crank lever 5 against the bias of springs 22, 25, the bellcrank lever comprising a fork 7 engaging a groove 9 in an operating sleeve slidden leftwards to compress a stack of Belleville springs 15, which force a positive clutch sleeve 16 splined upon a half-shaft 14 to engage inclined-face dogs 17 thereon with similarly shaped dogs 18 on the differential cage 19. If an overload occurs, the inclined faces of the dogs 17, 18 cam the clutch sleeve 16 rightwards against the compressed Belleville springs 15, and the dogs rattle over. The geometric arrangement of the lever 3 and the bell-crank lever 5.is such that the mechanical advantage thereof increases with depression of the pedal 1, so that the tractor driver can easily hold the pedal depressed against the rightwards movement of the clutch sleeve 16. When the pedal 1 is released, the springs 22, 25 return the levers &c. to the clutch disengaged position.

Title: Improvements relating to reversing mechanism for washing and like machines of the rotary drum type
IPC: D06F37/36
Filed: 1928-03-03
Abstract: 312,973. Tullis, A. F., and Napier, W. March 3, 1928. Reversing - gearing for washing-machines of the kind in which a drum 1 is automatically reversed every so many revolutions is adapted to enable the number of revolutions between reversals to be changed while the machine is operating. To effect this, change is made from one control device 8 to a separate control device 20. A driving - shaft 3 with pulleys 5 driven by open- and - crossed belts is geared to a main driving wheel 2. The belts are shifted by forks &c. 6 operated through a bellcrank lever from a reciprocating rod 7. The wheel 2 carries two pivoted kickers 13, 14, one for each direction of rotation. When the device 8 is operative, these kickers strike tappets 11, 12 on a sleeve 8 which is fed along rod 7 by successive impulses until it strikes a stop 9 or a stop 10, whereupon rod 7 is moved to shift the belts and effect reversal. The rod 7 is connected by a lever 18 to a second reciprocating rod 15 and a rack-and-pinion connection 23 is manually operable so as to turn the rods 7, 15 simultaneously. The tappets 11, 12 on sleeve 8 and tappets 20<a> &c. on sleeve 20 are thus brought alternatively into the plane of the kickers. The number of tappets on sleeve 20 is different to that on sleeve 8, and so the number of revolutions between reversals is varied by changing over. The rod 7 may be operated directly by a hand lever 24.

Title: Improved process of and apparatus for the extraction of sulphur from gases containing sulphuretted hydrogen
IPC: C10K1/34
Filed: 1920-03-06
Abstract: 169,467. Chemische Fabrik Rhenania, and Projahn, F. March 6, 1920. Sulphur is obtained from hydrogen sulphide, or gases containing more than 15 per cent of hydrogen sulphide, by downward passage in admixture with air through a kiln of the Claus type, but containing a thickened layer of contact material preferably bauxite. In the upper layer, the hydrogen sulphide and oxygen react to produce sulphur in accordance with the ordinary Claus process; whilst in the lower layer, which is thicker and maintained at a lower temperature, the waste gases from the upper layer, namely hydrogen sulphide and sulphur dioxide, interact according to the equation 2H2S + SO2 = 2H2O + 3S to produce additional sulphur. The initial gas mixture is admitted to the kiln through a pipe a, and after passing through an hydraulic seal band pipe c enters the upper part of the kiln through nozzles d and passes downwardly through the upper contact zone e and lower contact zone f, the products of the reactions emerging by pipe i. The contact material is preferably given a conical surface formation; and thermometer tubesk, reaching down to the layer of the inert material g on the grate h, are provided. The composition of the ingoing gas mixture is adjusted according to the results obtained from a small laboratory control furnace. Specifications 5070/83, 5958/83, and 5959/83 are referred to.

Title: Improved means for relieving the compression in the cylinders of internal-combustion engines to facilitate starting
IPC: F01L13/08
Filed: 1934-03-06
Abstract: 416,342. Cylinders. FEUNTEUN, M., 30, Rue Milton, Paris. March 6, 1934, No. 7136. [Class 7 (ii).] Prior to starting, cylinder clearance is increased by opening a valve 1, and thus adding the capacity of a supplementary chamber 3 to that of the normal combustion chamber to which the device is attached ; the valve closes automatically when the first explosion occurs, or when the cylinder compression reaches a pre-determined valve. The valve is opened by pressing a knob 2 and held open by coiled springs 8 acting through pivoted levers 7, or by leaf springs acting directly, on the sloping faces of a port 11 fixed to the valve, and closed by fluid pressure on the valve head and the pressure of a spring 10; when the sharp edges of the part 11 have passed the edges of the sloping faces on the levers 7, the valve is held closed. As modified in Fig. 9, a piston 12 is lifted by the fluid pressure to separate levers 7 and thus enable a part 11 fixed to the valve stem to jump from notches 21 to notches 22 and thus hold the valve closed. The piston 12 may be located at the side of the valve stem and operate a bell-crank lever to disengage a pawl. The capacity of the chamber 3 is varied by a locked stud which is screwed into the wall thereof or a nozzle venting the interior to atmosphere.

Abstract: 145,382. Phillips, F. W. March 22, 1919. Taximeters; actuating-details; resetting-mechanism, arrangement of.-The pounds and shillings fare dials are arranged concentrically, the pence dial is operated by the movement of the drive transmission lever under the combined action of gravity and a spring, and the shillings dial is actuated by a spring-controlled lever set by the transmission lever and tripped by the pence transfer tooth. The invention is described in connexion with the devices forming the subject-matter of Specifications 145,139 and 145,381. The pounds dial 24 is arranged in a recess in the shillings dial 23 and is actuated therefrom by a snail cam 48 controlling an arm 50 carrying a feed pawl 52, the stroke of which is limited to one tooth of the ratchet wheel 47 on the pounds dial spindle by a fixed pin 53. The pence dial 12 is operated from the transmission lever 18 raised against gravity and a spring 21 by a star wheel 8 driven by the clock or vehicle. A pin 17 on an extension of the lever co-operates with the shaped edge 16 of a lever 9 which carries the feed pawl 14 of the pence dial. The pawl is limited in its forward movement by entering between the ratchet teeth 11 and a fixed pin 15 and correct setting of the dial is ensured by a spring pawl. Transfer from the pence dial to the shillings dial is effected by a tooth 40 which rocks a lever 39 and so withdraws support from a pin 37 on the shillings feed-lever 36 carrying the spring-controlled pawl 34. After the transfer has taken place, this lever 36 is reset by engagement of an arm 42 of the transmission lever 18 with a roller 43 on the lever 36.
