IPC: B62K25/24
Filed: 1927-05-04
Abstract: 284,118. Osborn, F. J., and Wood, N. F. May 4, 1927. Steering-mechanism.-The invention comprises an improved frame of the duplex type for motorcycles and like vehicles having a single steering- wheel, and improved steering-mechanism particularly applicable to such frame. The frame comprises a pair of top members 1, Figs. 1 and 2, a pair of bottom members 2, a pair of steering- heads 3, and struts 8, the two side frames thus formed being connected by cross bracing 4. Rotatably mounted in each head 3 is a steering- column 9, to the upper and lower ends of which are secured links 11, the forward ends of which are secured to a rod 12; the columns 9, links 11, and rods 12 thus form a pair of rigid frames capable of swinging about the axes of the heads 3. The wheel axle 6 is carried by lugs 13 slidable on the rods 12. The upper ends of the rods 12 are connected by a pivoted link 14, to which the handle-,bar 5 is secured. In steering, the handle-bar 5 moves the links 14, 11 as indicated by dotted lines in Fig. 4, the axle 6 moving in similar manner to the link 14, the centre of which traverses the path S. The front parts 2<a> of the bottom frame members 2 are outwardly bowed to allow sufficient angular movement of the wheel for steering purposes. The wheel-carrying lugs 13 are acted upon by compression springs 15 and rebound springs 17 mounted on the rods 12. In a modification, the springs 15, 17 are surrounded by sleeves in which the lugs 13 slide, the axle-carrying portions of the lugs extending through slots in the, sleeves. As a further modification, the axle 6 may be carried by links pivoted to fixed lugs 13 and controlled by springs in known manner.

Title: Improvements relating to internal combustion engines
Inventor: WEST HAROLD EDWARD WILLIAM
IPC: F02C7/277
Filed: 1954-04-26
Abstract: 774,695. Engine turning-gear. ROLLSROYCE, Ltd. April 26, 1955 [April 26, 1954], No. 12074/54. Class 7 (5). [Also in Groups XXVI, XXIX and XXXV] A power plant comprises an internal combustion engine 9, a gas turbine 23 for rotating the engine in starting and supplied with pressure gas from an external source during starting and thereafter supplied with pressure gas from.the engine or from another engine in the plant, and an electrical generator 45 having a drive connection with the turbine and cooled by exhaust gas from the turbine. As shown the internal combustion engine is a gas turbine, the shaft 13 of which is connected by gearing 14, 15, 18, 22 and a reduction gearing 24 to the starting turbine 23, a freewheel device 16, 19, 20 being incorporated in the gearing to permit the drive from the turbine 23 being rendered ineffective when the turbine 9 reaches a self driving speed. The turbine 23 drives the electrical generator, which is an alternator, through a hydraulic coupling 33 of the kind to which a continuous flow of fluid must be supplied to prevent slip. Depression of a switch 68 in a starting circuit causes solenoids to set valves 26, 40 to connect the turbine 23 to a cartridge or air bottle 25 and to shut off supply of fluid to the coupling so that the turbine 23 rotates the shaft 13 of the turbine 9 only. When the shaft of the turbine 9 attains self driving speed a governor 71 breaks the starting circuit and the valves 26, 40 are set in the positions shown to supply gas from the compression stage 10 of the turbine 9 to the turbine 23 and to supply lubricating oil from the engine to the coupling so that the alternator is driven by the turbine 23. The air exhausted from the turbine 23 is led by a line 42 to cool the alternator. The frequency of the alternator is controlled by a servo mechanism (see Group XXIX) which actuates a valve 58 controlling the speed of the turbine 23 by metering the air supply. The valve is also controlled in accordance with the pressure of gas so that the turbine 23 maintains a constant speed under constant load. The hydraulic coupling may be dispensed with, the field circuit of the alternator being broken by a solenoid controlled switch during the starting of the turbine 9. A flame tube and burner may be connected to the air bottle so that the turbine 23 is driven by hot gases during the starting, means being provided to by-pass the exhaust of the turbine 23 from the alternator during the starting. An additional hydraulic coupling may be fitted between the turbine 23 and the reduction gearing to cut out the drive to the turbine 9 when the turbine 23 is driving the alternator. The servomechanism may be replaced by an electrical circuit controlling a motor actuating the valve 58 (see Group XXXV). According to the provisional specification gas from the combustion chamber of the turbine 9 may be used to drive the turbine 23 after starting of the turbine 9.

Abstract: 1,101,484. Wrapping articles. R.P.M. Inc. 24 March, 1965 [26 March, 1964], No. 12560/65. Heading B8C. An article 11 having a wrapper 12 lying across its top surface, with leading and trailing flaps 12b, 12a hanging down, is conveyed in a predetermined path over rotary means, the peripheral speed of which exceeds the speed of the article, the rotary means having a radial slot through which the flaps 12b, 12a may fall so that the trailing flap 12a is swept on to the underside of the article by the rotary means and the leading flap 12b is folded into overlapping relation with the flap 12a by means downstream of the rotary means. As described, the article 11 carrying the wrapper 12 is conveyed rectilinearly by fingers 50 of a chain conveyer (32), Figs. 1-3 (not shown). Stationary guides 52 engage the upper wrapper surface, and their height is adjustable. The article is thus delivered from a table 30 to co-planar rotary discs 62, 64 having slots A, B so as to arrive at the position of the left-hand article in Figs. 7A, 7B, where flap 12b falls through the slots. The edges D of slots A, B of the discs now engage the trailing flap 12a intermediate its edges and fold its central portion against the underside of article 11, simultaneously applying outward wrinkleremoving friction forces, Figs. 5A-5C (not shown). The apex 92 of the stationary folding plate 60 engages the leading flap 12b to fold its central portions over the central portions of flap 12a to overlap the latter outwardly. Increasingly peripheral portions of the flaps are then folded against the underside of the article 11 until the latter is completely encircled by the wrapper, as shown by the right-hand article of Figs. 7A, 7B and also in Fig. 8 (not shown). The number of slots may be varied and there may be one rotary disc only. An infeed conveyer (10), Fig. 1, may deliver the partially wrapped articles to conveyer 32. The flaps 12a, 12b may be glued or heat-sealed together. The open side edges of the wrapper may be closed by known means to form side flaps.
