Title: Improved machine for canneluring, circumferentially indenting or crimping detonator cases, thin tubes or like articles
IPC: F42B33/12
Filed: 1926-02-06
Abstract: 270,399. Greenwood & Batley, Ltd., and Barker, J. H. Feb. 6, 1926. Corrugating.-Detonator cases, thin tubes, &c. are crimped circumferenti ally by rolls 49, 50, 51 mounted on intergeared parallel shafts, one 23 of which is connected by links 25 loosely mounted on another one 4 of the shafts, the shaft 23 being controlled by linkage from a rock shaft 32 which may be actuated by a hand lever, hanging weight, &c. The shaft 4 is driven by a belt and carries a loosely mounted roll 50, the remain. ing rolls being secured to their respective shafts. The work is placed in a longitudinally slotted tube 40 within which a stop 45 slides and may be clamped in the adjusted position by a screw 47. Detonators 66 and safety fuses 68 for aerial bombs &c. may be crimped together. The rolls may be so formed on their peripheries as to give corrugations of the required character.

Title: Guided transport system
IPC: B61B13/00
Filed: 1973-01-23
Abstract: 1403662 Track switches P PATIN 23 Jan 1973 [3 Feb 1972 13 July 1972] 3461/73 Heading E1G [Also in Division B7] A guided transport system includes vehicles running on wheels with tyres 10d, 10g, Figure 3, the vehicles being guided by guide wheels 16, 17, 20 engaging with guide rails 1d, 1g to define a track, and the system including at least two tracks intersecting at a set of points, Figure 7, the guide rails 1, 2, 3, 5d and g being flexible in the region of the points and being movable under the control of a reciprocable control rod 34 between positions (shown in dotted lines) defining two parallel straight tracks and the positions shown in Figure 7 in which vehicles may be switched from one track to the other. The guide rails in the region of the points are connected by means of shafts 29, 31 to cross pieces 32 slidable in recesses 33 in the track. The control rod 34 is provided with grooves 43 (Figure 11) engageable with runners as 41a, 41d on the cross pieces 32, the grooves 43 being inclined in the direction of movement of the control rod 34 so as to effect the desired movements of the guide rails. In the construction shown in Figure 11 the movement of the control rod 34 is effected by means of a pedal 49 operated by passage of the vehicle wheels. Resilience of the guide rails returns them to their original positions after passage of the vehicle. The guide rails may be used as current supply conductors via sliding contacts (not shown) on the vehicles. To this end, the guide rail 21, Figure 6a, is carried on an insulator 23 secured by bolts 26a, 26b. The shafts 29, 31 supporting the guide rails at the points may also be of insulating material. As an alternative to the vehicle shown in Figure 3 in which the centre guide wheels 20 are fixed, these wheels may be carried on a slidable cross piece 7, Figure 13, connected by springs 13a, 13b to a rocker arm 9 in turn connected by joints 10a, 10b to poles 11a, 11b fixed to the supporting wheel axles 2a, 2b, these axles being pivoted at 4a, 4b to the vehicle body. In this way the axles 2a, 2b follow curves in the, track under control of the movements of the cross piece 7.

Title: Hydraulic jacks
IPC: B66F3/42
Filed: 1946-02-04
Abstract: 607,626. Hydraulic jacks. PAGE, H. E. Feb. 4, 1946, No. 3483. Convention date, Feb. 3, 1945. [Class 78 (iii)] A hydraulic jack, adapted for rapid engagement of the lifting lever 32 with the load, comprises a pair of side-by-side cylinders 5, 8 of different diameter and each having a work piston 25, 40 connected to an arm 30 of the lifting lever. Pressure generating means associated with the smaller cylinder 5 delivers pressure fluid to it from a reservoir R to force the piston 25 outwardly to engage the lever 32 rapidly with the load, when the consequent rise in pressure in the smaller cylinder delivers fluid from it to the larger cylinder 8 so that the piston 40 then becomes effective to raise the load. In the construction shown the pressure generating means is a pump piston 10 working behind the piston 25 in the cylinder 5; it is reciprocated by an actuating lever 17, and has a cup-washer 11 for tak ng-up fluid delivered from the reservoir R through a connection 43. The pressure space B of the cylinder 5 has a connection 50 with that of the cylinder 8, and in this connection is a spring-loaded cheek-valve 52 adjusted to pass fluid from the spare B to the larger cylinder when the pres-, sure rises as the load is taken up. To enable the piston 40 to move forward freely, whilst the piston 25 is alone operative, it is furnished with a cup-washer 41, and the cylinder space D behind it is connected with the reservoir. To lower the load, valves 47 and 49 are opened to pass the pressure fluid back to the reservoir. The two cylinders are separately pivoted at 37 and 38 to the body 12 of the jack to which the lifting lever is pivoted at 35.

Abstract: 1496932 Controlling air pressure in pneumatic tyres Y TSURUTA 28 Jan 1975 [30 March 1974] 3607/75 Heading B7C The air pressure within the inner tube 13 of a vehicle or aircraft wheel or within tubes 34 controlling the position of anti-skid studs 31 relative to a vehicle wheel is controlled by changing the volume of chamber 10, such a change being achieved by mechanical means, or by fluid under pressure supplied from a source, under the control of control means. As illustrated, the change is achieved by the movement of piston 7 is response to the operation of control means 15A to effect supply to, or exhaustion from, chamber 5 of a pressure fluid, e.g. air or a liquid. In an alternative embodiment (Fig. 3, not shown) the chambers (10, 25), and the piston (27). between the chambers are annular. In each embodiment the piston 7 comprises two parts separated by a ball bearing 9, so that the outboard part can be rotated with the wheel relative to the inboard part.

Filed: 1929-02-05
Abstract: 310,023. Mergenthaler Linotype Co., (Assignees of Kingsbury, G. P.). April 21, 1928, [Convention date]. Magazines for type-bar-making machines.- Relates to machines having locking-means for preventing disengagement of the magazine and the escapements until the matrices have been locked within the magazine. According to the invention, the locking-means are controlled by a matrix locking-bar, which is permanently mounted on the magazine, and is movable rotatably for locking the matrices, and lengthwise for actuating the locking-means. In machines in which the magazine is movable away from the escapements, the locking-device is of the known form comprising a spring-pressed latch-member or lever D, Fig. 1, the rear end of which is normally in the path of a finger E, which swings forwards as the magazine is lifted. The finger E is on a shaft E', which can be rocked by means of arms E', and has a cam-plate E<2> for raising the magazine. The matrix locking-bar F, Fig. 3, is journaled by means of trunnions F<1>, F<2> in the sides of the magazine, and is rotatable by means of a handle F<3>. The bar is formed as shown in Fig. 7, so that, in one position, it engages the ears of the matrices. In the inactive position of the bar, the shank of the handle rests against the face of a bearing-block A<11>, Fig. 3, and is retained by a spring detent A<12>. When the bar is turned into the locking position, the shank of the handle registers with a slot A<13>, so that the bar can be moved endwise, to operate the latch D, and to permit the magazine to be raised. The handle is then raised slightly into an offset portion of the slot A<13>, so as to prevent endwise movement of the bar, and is held in position by engagement of the detent A<12> with an arm F<5>, Fig. 7, on the bar.
