Title: Improvements in and relating to frames for reciprocating engines
IPC: F16M1/02
Filed: 1932-01-02
Abstract: 396,742. Bed-plates and frames. ALLEN, R. W. and STRUB, R. E., Queen's Engineering Works, Bedford. Jan. 2, 1932, No. 152. [Class 7 (ii).] Reciprocating engines are built up from plates of C-form arranged at right-angles to the crank shaft and having apertures open on one side for the reception of the shaft. A cylinder-carrying horizontal plate parallel to the shaft connects the C-plates. Cover plates may be provided. The plates are provided with supplementary strap or bracing means. The joints are interlocked or keyed and welded. In the frame for an internal-combustion engine shown in Fig. 1, a series of vertical plates are arranged at rightangles to the crank shaft 2 between the cylinders and are connected to a transverse member 4 extending the length of the frame. Frame and crank shaft bearing members 5, 6 are provided. The plates 1 are attached to the plate 4 at spaced points by lugs entering slots therein. The connections are welded. Reinforcing- straps 10 surround the plates 1 and engage recesses or slots in the plate 4. In a modification, Fig. 6, the plate 1 has cut-away lugs which enter the plate 4 and are secured by welding. The studs securing the cylinder heads may be partly screwed into each of the plates 4, 1. In the modified frame shown in Fig. 8, the reinforcing-strap 10a surrounds and is welded to the plate 4. A strap 16 reinforces the crank-shaft opening. Lugs on the plate 16 enter apertures in the strap 10a, a cover plate 19, and securing-strips 18. The crank-shaft openings in the plates 1 are closed by a plate running parallel with the shaft and provided with inspection opening. This closing-plate is secured by welded dovetailed and spigot joints The closing-plate may be replaced by tie bolts or struts 22, Fig. 16, or both. In a modification, flanged columns are used to close the gaps. In a further modification, Fig. 20, the members 1 are made in two parts with oppositely-directed flanges. A pair of bolts 22 is used to close each gap. In further modifications embodying pairs of plates, strut columns or pairs of flanged strut plates are used. A further modification is described wherein the plates at right-angles to the shaft are of L formation. These are secured to the transverse cylinder plate by C-form straps which embrace them and are continued under the crank-shaft bearing. Vertical strengthening plates are inserted in the upper portion of the C-plates. The main plates may be flanged or reinforced on their outer edges. Methods of securing single and double vertical plates to the plates 4 are described. In the construction shown in Fig. 29, the C-plates 1 have attached extension plates which extend to members 46 ; the extension plates have -camshaft apertures and bearing-rings 41 welded thereto. The water cooling-jackets of the cylinders 3 are formed by a single bent plate 42. A bent plate 46 is arranged to enclose the cam shaft and provide an oil tray.
Patent GB-595324-A (GB)
Title: Improvements in or relating to radio tuning structure
IPC: H03J5/16
Filed: 1945-01-02
Abstract: 595,324. Push-button tuning mechanism. CRAMER, S. S. Jan. 2, 1945, No. 183. Convention date, May 23, 1944. [Class 40 (v)] A push-button tuning arrangement is characterised in that the tuning member is initially moved to one of its extreme positions and then automatically moved towards its other extreme position until stopped at a predetermined tuning position by the engagement of a flexible blade, mounted to rotate with the tuning member, with a part of a member which is pushed into the line of travel of the blade, such movement also closing a circuit which causes the initial movement of the tuning member. On depression of any one of the plungers 35, Fig. 9, spring switch blades 50, 55 contact each other and! current flows through the solenoid 8, (see Fig. 10), mounted on the back of the framework of the tuning condenser. This causes an armature 10 to move through the solenoid 50 causing the shaft 5 carrying the movable condenser blades to rotate to one of its extreme positions. At this point an extension 21 of the armature contacts a plunger core 19 of an electromagnet 17 so breaking the circuit of the solenoid and completing the circuit of the electromagnet 17, contact 26 moving from contact with 25 to 28. This allows the shaft 5 to rotate towards its other extreme position under the influence of the coiled spring 13, (see Fig. 4 and 3). Fixed to the shaft, near the front end, is a pair of spaced flexible blades 60, 61, (see Fig. 4, 5, 9), one of which comes into contact with a pin 37 which extends from the disced-end of the depressed plunger 35 so stopping the shaft 5. The plunger is released, so breaking the contact between the spring fingers 50, 55 ; but the tuning remains fixed, since the flexible blade is held, with slight lateral displacement by the pinhead 38 until another plunger is depressed.. The position of the pin 37, and therefore the tuning position to be selected, may be varied by manual rotation of a button 34 in which the plunger 35 is slidably, but not rotatably, mounted. Manual tuning is effected by the axial displacement along the shaft 7 of a gear-wheel 63 until a pin 64 stops the return motion of the shaft by engagement with a flexible blade 66, (see Fig. 3). Thus held, the shaft is turned by the rotation of the tuning knob 76 whose initial depression causes the closing of the circuit of the solenoid 8 and the lateral displacement of the gearwheel. The solenoid 8 and the co-operating spring 13 are the subject matter of U.S.A. Specification 2,337,375. U.S.A. Specification 1,800,719 also is referred to.

Patent GB-869639-A (GB)
Title: Liquid meter
IPC: G01F3/20
Filed: 1958-01-06
Abstract: 869,639. Liquid meters. HERMAN, J. F. Jan. 6, 1958 [Jan. 5, 1957]. No. 494/58. Classes 69 (1) and 69 (2). [Also in Group XXXVIII] A liquid meter comprises two elastic capacities associated with distributing means for filling, by the flow of fluid to be measured, one of the said capacities while the other capacity is emptied, and means for counting the number of fillings thus giving the quantity of liquid delivered. The two capacities are formed by a single bellows divided into two capacities by a partition in such a manner that said partition is displaced when one capacity is filling and the other is emptied, said movable partition controlling electric contacts which provide impulses of current controlling the means of distribution of the liquid to one or other of the capacities. Liquid to be measured enters the meter through passage 108, Fig. 1, and passes through orifices 110 into a bellows 102 which expands to move a partition 103 towards two electrical contacts 118. When the partition meets the contacts 118 the pairs of electromagnets 116, 117 are actuated causing the closure member 114 to move to open orifices 110 and close orifices 112. Similarly, closure member 115 moves to close orifices 110 and open orifices 112, both closure members being permanent magnets. Fluid then flows via orifices 110 into bellows 101 and as the bellows fills the partition 103 moves to the right expelling a quantity of fluid from bellows 102 into the outlet passage 109 via orifices 112. On reaching the contacts 119 the process is repeated and fluid is expelled from bellows 101. A backwards and forwards motion of partition 103 thus occurs with corresponding impulses of current. These impulses are recorded on an impulse counter and since each displacement of the partition 103 corresponds to a flow of liquid of known volume the total volume of liquid passed is determined. Instead of pairs of electromagnets two single electromagnets may be used.
