Title: A device for applying pressure to an actuating member displaceable by pressure to actuate a brake or clutch
IPC: G05G25/00
Filed: 1934-03-10
Abstract: 436,368. Operating clutches. BURGESS, S., 41, St. Vincent Place, Glasgow. -(Aktieselskabet Burmeister & Wain's Maskin- Og Skibsbyggeri; 9, Overgadenneden Vandet, Copenhagen) March 10, 1934, No. 7626. [Class 80 (ii)] [See also Group XXXIV] An operating means for a brake or clutch, more particularly for a brake operating a marine reversing gear comprises an operating lever 3 adapted to actuate a pressure member or spindle 10 through a spring 13 into or out of engagement with a brake actuating member 2, the spring normally tending to move the pressure member towards the actuating member and the stress of the spring being adjustable to substantially the same magnitude as the force required to operate the brake or clutch. The spring 13 bears on a part 11 fixed to the lever 3 and a slidable part 14 in which is adjustably screwed the spindle 10 which is locked by a nut 16. When the brake is applied, the spring is compressed and the yielding of the spring is indicated by the distance moved apart by parts 14, 17. The lever 3 is operated by a screwed spindle 7 and its movement is limited by a stop 18. Wear of the brake will be indicated by a lessening of the distance moved apart by the parts 14, 17.

Title: Improvements relating to drive mechanism for furnaces of the conveyorbelt type
IPC: F27B9/24
Filed: 1933-03-14
Abstract: 416,850. Driving-gear for endless-belt conveyers in furnaces. BIRMINGHAM ELECTRIC FURNACES, Ltd., and LOBLEY, A. G., Birlec Works, Tyburn Road, Erdington, Birmingham. March 14, 1933, No. 7666. [Class 51 (ii).] Relates to heat-treatment furnaces of the kind in which work or goods are carried therethrough on a belt-type conveyer, and to means for driving the conveyer at speeds which vary within fractions of a foot per minute. An electric motor A on the roof of the furnace through reducing- gearing a drives an eccentric c which through a connecting-rod d rocks a lever e about a fixed pivot e<1> with constant amplitude. The lever e carries a screw e<2> with a nut e<3> connected by a link f to one arm of an elbow lever g the other arm of which is jointed to a rod g<1> connected to a rocking arm g<2> which through a roller ratchet i drives a disc i<2> on the spindle h of one of the drums, not shown, of the conveyer. By turning a hand-wheel e<4>, the nut e<3> is moved towards or from the pivot e<1>, and so the throw imparted to the ratchet lever g<2> for each turn of the eccentric c is varied, and in consequence the speed of the conveyer is adjusted. To prevent damage by obstruction, a suitable slip clutch j may be arranged between the diso i<2> and drum spindle h<1>. To the same end, the link f may be in two telescoping parts connected by springs m. The drive may be duplicated to the spindle h<2> of the other conveyer drum by a duplicate train g<3>, g4, is, i<4>.

Filed: 1923-03-19
Abstract: 198,334. Hartford Rubber Works Co., (Assignees of Steinle, W. J.). May 23, 1922. [Convention date]. Tyre covers, making.-A tyre cover is built up in band form with the edges of normally less diameter than the intermediate portions, and shaped to tyre section by forcing together the edge portions preferably without the use of fluid pressure or other distending means. The band 9 is built on a cylinder 1, Fig. 2, of greater diameter than the normal diameter of the beads 8 so that, when released, the latter contract causing the band to assume the curved section shown in Fig. 6. The band is then laid over a spacing- ring 10 on a drum 16, Fig. 5, and by means of profiled pressure-rings 12 the edges 11 are forced towards one another until clamped against the ring 10. The thin side walls of the shaped cover are supported by the rings 12, and the ring 10 is rounded off at 15 to prevent chafing at the beadlines. Fig. 6 shows an apparatus for shaping the band in which the lower pressure-ring 46 is mounted on a fixed support 22, the upper pressure-ring 45 being carried by the flanged head 24 of a cylinder 25 fitted with a stationary piston 30. A valve 32 controls the admission of pressure-fluid to either end of the cylinder so as to raise or lower the ring 45. At the edges, the inner face of the band may be cemented &c. so as to adhere to the ring 10 on which the shaped band may be moved to the vulcanizing-mould. The ring 10 may be formed with a passage 10<1> for the admission of pressure-fluid during the shaping or vulcanizing processes. Specifications 122,137, 127,990, and 148,077, [Class 70, Indiarubber &c.], are referred to.

Title: Improvements in or relating to fuel injection pumps
IPC: F02M41/12
Filed: 1969-02-14
Abstract: 1,249,162. Fuel injection pumps. ROBERT BOSCH G.m.b.H. Feb.14, 1969 [Feb.16, 1968], No.8025/69. Heading F1A. A fuel injection pump is of the type in which the quantity of fuel delivered is varied according to engine speed by a regulating spool 14 which controls the opening of a spill passage 15b and which is driven in one direction by pressure liquid delivered from an auxiliary pump 18, 19 driven synchronously with the injection pump, the return stroke of the spool 14 being retarded by a variable regulating throttle 30. The auxiliary pump has a by-pass passage 33a which has a throttle comprising a throttle 48, Fig.2, and a closing element 35 which is opened by a spring 37 and closed by speed dependant pressure liquid. The crosssection of the throttle 48 is variable simultaneously with the cross-section of the regulating throttle 30 by rotating the member 28. The cross-section 30 may also be varied by axial movement of the member 28. For starting the cross-section 30 is opened together with the throttle 48 and the closing element 35, and thus all the fuel delivered by the auxiliary pump flows into a suction space 4. On reaching a specific engine speed the element 35 is closed by pressure in the suction space 4 which is speed dependant and thus no more fuel can by-pass the passages 22, 25. As the engine speed continues to increase the cross-section of the regulating throttle 30 is reduced simultaneously blocking the passage 33a so that no fuel flows off by way of this passage.

Title: Conical-type stone crusher
IPC: B02C2/04
Filed: 1937-03-19
Abstract: 484,531. Gyratory crushers. SCHIEFERSTEIN, G. H. March 19, 1937, No. 8100. Convention date, March 23, 1936. [Class 59] [Also in Group XXIV] A gyratory crusher comprises an internal cone attached to an outer casing, between which is arranged a concave resiliently supported by the casing, the cone and casing being driven through a loose coupling whereby the cone and casing and the concave perform circular oscillations with a phase displacement of 180‹ whereby a crushing action is produced. As shown in Fig. 1 the cone a and casing d are connected together by spokes e or bolts, the casing being supported on spring supports f. The concave b is suspended by ball-jointed members g which are movable by bolts i on the casing cover t to vary the gap between the cone and concave, and resilient bodies c of rubber &c. which may be adjustable to vary the pressure, form a resilient connection between the concave b and casing d. The drive shaft w drives a crank k<1> which is connected by its pin z with a crank k<2> pivoted to the cone a whereby on rotation the inertia of the cone a and casing causes a lag between cone and concave such as to compress the bodies c with a certain phase displacement which increases rapidly to 180‹. The concave b, or both crushing members are fluted or toothed on the surfaces forming the mouth of the crusher. In Fig. 3 the outer casing d is in the form of a cone and is connected to the crushing cone a by bolts el, resilient bodies c, c<1> pressing on the outside of the concave b, which is supported on resilient members f, and a driving cone k respectively. The crushing cone a is connected loosely to the cone k by a ball-headed bolt w<1> and a ball joint v on a cross-head t<1> at the base of the cone engages eccentrically in a bearing on a driving gear r<2> whereby the cone k describes reeling movements about the ball joint w<1> and the resilient means c<1> are periodically compressed thereby causing the two crushing members to describe relative circular oscillations with a phase displacement of 180‹. The ball v may slide in a slot or the cone k may be driven by an eccentrically mounted weight. The drive may also comprise a cardan joint, Fig. 4, with elliptical bearings x<4> and rubber bushes u<4> the end of the shaft z<1> receiving circular oscillations. The bodies c may be mounted on pivoted levers and adjusted by a screw-bolt.
