Title: Improvements in chucks
IPC: B23B31/16
Filed: 1929-04-15
Abstract: 335,167. Whiton, L. E. April 15, 1929. Chucks are provided with means for manually or mechanically operating the jaws whilst rotating the rate of movement of the jaws being automatically controlled in order to intensify the gripping pressure. The chuck body 15, Fig. 1, is mounted on a hollow spindle 13 and houses the scroll cam 14 which is clutched to an internal gear ring 20, geared, by intermediate pinions 24, to a sleeve 16 loose on the chuck body. A second sleeve 18, loosely mounted on the sleeve 16 is in gear through pinions 25, mounted on the same spindles as the pinions 24, with an internally toothed fixed ring 22. The sleeves 16, 18 are geared, by wheels 27, 28, to pinions 33, 34 mounted on a shaft 31, driven manually or by power. The wheel 28 is pinned to a ring 36 having an arcuate slot 37, Fig. 3, through which pass stationary spring-pressed pins 40, 41 adapted to apply frictional drag to the ring 36. Teeth are omitted from a portion of the outer periphery of the wheel 28. In operation, the jaws remain at the same radial distance while the chuck is rotating, till the shaft 31 is actuated, whereupon relative motion occurs between the ring 20 and the chuck body, producing movement of the scroll cam and actuation of the jaws. On the jaws encountering resistance the drag on the ring 36 overcomes the frictional resistance of the pins 40, 41 and the gear 28 is engaged with the pinion 34, whereby the scroll cam is actuated by the differential action of the pinions 33, 34, thus applying a slower but more powerful grip. When both pins 40, 41 are used, no change in the mechanical advantage of the system takes place. Either of the pins 40, 41 is used according to whether the chuck is to apply internal or external grip. Various constructions of the pins for applying drag to the member 28 are described. The scroll cam may be actuated by the key spindle 65, Fig. 11, which is provided with teeth gearing with the scroll cam and with the wheel 20a, the wheel 28a being permanently fixed. The mechanism may be applied to actuate radial screws operating the jaws, and also to actuate sleeves 76, Fig. 13, controlling members 75 having projections which move the jaws. The differential motion for actuating the jaws may be obtained by a manually operated clutch 98, Fig. 14, adapted to engage either a sleeve 99 to hold the gear ring 28 stationary; or a sleeve 97 to enable both the gears 27 and 28 to be driven at differing speeds, by the shaft 91.

Title: Improvements in and relating to spray carburettors for internal-combustion engines
IPC: F02M7/133
Filed: 1945-05-07
Abstract: 603,296. Spray carburetters. SOC. ANON. SOLEX. May 7, 1945, No. 11629. Convention date, July 11, 1941. [Class 7 (iii)] Fuel for enriching the combustible mixture during acceleration and under heavy load is fed through an auxiliary nozzle 13 controlled by a valve 15 actuated by two spring-loaded diaphragms 19, 20 of unequal areas. Suction near the throttle valve 2, which is conveyed to the space between the diaphragms by the pipe 21, keeps the valve 15 closed until opening of the throttle valve reduces the suction to a predetermined value. A small amount of fuel may flow continuously from chamber 10 through a calibrated orifice 17. An accelerator pump comprises a chamber 28 containing fuel sealed by a diaphragm 24, sudden opening of the throttle valve at low speeds causing a lever 25 to depress the diaphragm and force additional fuel through the valve 15 and orifice 17. A rod 38 fixed to the diaphragm 24 opens the valve 15 at the end of the pump delivery stroke. The lever 25 is adjustably connected to the throttle valve by a rod 30 fitted with a transverse pin 36 and sliding in a sleeve 32 with slots 34 of various lengths, a spring 37 allowing lost motion if the pump is actuated at high speeds with the valve 15 held closed. Specification 531,778 is referred to.

Title: Method and apparatus for making a die member complemental to a die member of the rule type
IPC: B23H9/12
Filed: 1966-03-17
Abstract: 1,136,716. Making dies; electro erosion. TEMPLET INDUSTRIES Inc. 17 March, 1966 [23 Oct., 1965], No. 11707/66. Headings B3A and B3V. A die member complementary to a rule die is formed from a metal plate 86, Fig. 14, by electro erosion using the rule die as an electro erosion tool. The rule die comprises rule die sections 60 and punches 62, 64, Fig. 7, inserted into slots and holes cut in a plywood die block 30. The rule die sections 60 project from the finished rule die and may be tipped with an expendable metal suitable for performing the electro erosion process. After machining the plate 86 the surplus material on the sections 60 is removed by grinding. The die block 30 has a conductive coating 34 of copper or aluminium which may be applied to either side of the die block, before or after insertion of sections 60, and which serves to conduct electric current during the electro erosion process. Passages 70 are provided in the die block adjacent the sections 60, and holes 66, 68 are provided in the punches 62, 64 for the flow of dielectric fluid from a plenum chamber 100 which forms part of a die mounting fixture 72. The die block is clamped to the bottom of the plenum chamber by 4 banks, two of which 110, 114 are shown. Compressive force is exerted on the die block by tightening screws 116, 118 and this insures good electrical contact between the sections 60, the conductive coating 34, and the mounting fixture 72. The base of the plenum chamber may be provided with a perforated wall 104 which is supported by elements 108. A seal 122 limits loss of fluid at the sides of the die block. The electro erosion process is carried out using a machine 76, having a tank 78 containing dielectric fluid 82 which is circulated by a pump 80. When the electro erosion process is carried out the plate 86 may be completely pierced in one step, or may be first lightly eroded to mark out the profile of the rule die, then removed and machined by conventional means such as drilling, sawing, routing &c. to remove all but a small amount of scrap, then replacing in the machine for the final machining by the electro erosion process. In the latter case the holes 132 at the location of the punches are made slightly larger than the holes 66 in the punches so flow of dielectric fluid through the bores induces a flow of fluid through the interelectrode gap. After the plate 86 has been machined surplus material is removed from the sections 60 and punches 62 64 by grinding.
