Title: Improvements in and relating to Direction Signals, particularly for Motor Vehicles.
Inventor: ANDERSON JAMES
IPC: B60Q1/34
Filed: 1917-08-10
Abstract: 111,989. Anderson, J. Aug. 10, 1917. Road traffic signals on vehicles.-A turning and stopping indicators for road vehicles consists of a glazed casing 10 in the form of two arrows 19, 20 pointing in opposite directions with their shafts 17, 18 overlapping, a central partition 15 dividing the casing into two parts so that each arrow can be illuminated separately. The arrow heads are preferably covered with red glass 30 and the shafts with blue glass 31, the glass being carried by a removable face-plate 26 having a marginal flange 27 fitting around the casing. The partition 15 is bent at its rear end so as to form semi-cylindrical reflecting-surfaces 16, behind which pass the leads to the lamps 21, 22. In a modification, a third vertical arrow-shaped chamber is provided and serves as a '' stop " signal. Indicators may be placed at the front and rear of the vehicle, and wired so that both indicators are controlled bv a single switch.
Patent GB-114935-A (GB)
IPC: F04D27/02
Abstract: 114,935. British Thomson-Houston Co., (General Electric Co.). June 8, 1917. Regulating or controlling.-A pulsation-preventing valve for a centrifugal compressor placed in the inlet or in a by-pass is actuated in accordance with the volume handled by the machine and the discharge pressure. A compressor 6 and turbine 5 are mounted on a shaft 7, the turbine being provided with a governing valve 8 actuated bv a fluid motor 10 having a pilot valve 15 with a stem connected to a floating lever 17, one end of which is connected by a link 18 to an arm 19 pivoted to a fixed support 20 and connected to the motor-actuated rod 11 by a pin and slot. The other end of the lever 17 is connected by a link 22 to a lever 23 connected to the governor 26 of the turbine and also connected by an arm 27 to the beam 28 of a constant volume governor. The beam 28 is pivoted at 29 and is tilted by a, float 31 in the intake 32. The governor weight 34 is adjusted by a rod 35 having oppositely threaded portions 36, 37 and a hand-wheel 38. The turbine is normally under the control of the constantvolume governor only, the speed governor only coming into action in case of emergency. A throttle-valve 45 is arranged in the intake of the compressor and is operated by an arm 46 moved by a fluid-operated motor 48 having a pilot valve 50, the stem of which is connected to a floating lever 52 connected by links to a floating lever 54 and to the arm 46. One end of the lever 54 is connected by a link 56 to a block 57 sliding in guideways 58 in alinement with the pivot 29 of the beam 28. A plate 60 having a cam-slot 61 slides in guides 59 on the beam. A pin 62 on the block 59 projects into the cam slot 61. The plate 60 is connected by a rod 63 to a nut 64 engaging the threaded part 37 so that the plate 60 is traversed when the weight 34 is adjusted. The other end of the lever 54 is connected to the stem 65 of a piston 67 actuated by pressure in the discharge conduit 41. A spring 69 opposes the movement of the piston and is provided with adjusting means comprising a sleeve 70 on which is screwed a nut 72 to which the spring is fixed, and a member 74 which abuts against a shoulder 73 on the rod 65 and to which the other end of the spring is fixed. By turning the member 74 by a handwheel 75 the nut 72 is moved up or down and the tension of the spring adjusted. In operation, supposing the weight 34 of the volume governor to be adjusted to the right, the block 57 will be moved upwards by the cam slot 61 owing to the traversing of the plate 60, and the valve 50 will be operated through links 56, 53 to admit fluid to the motor 48 and close the valve 45 slightly. The position of the pilot valve is restored through the follow-up arrangement 55, 52. Increase of pressure in the outlet will act through the rod 65 to tilt the lever 54 about the end of the rod 56 and operate the valve 50 so as to close the valve 45 partially. The position of the valve 45 therefore depends on both the volume and outlet pressure of the fluid.

Abstract: 942,951. Percussive tools. ROBERT BOSCH G.m.b.H. April 4, 1960 [April 4, 1959], No. 11750/60. Heading B4C. A motor-driven hammer comprises a casing in which a hollow cylinder having a transverse wall and a piston within the cylinder are axially slidable with the piston or serving as an impact body and the other as a member driven by a prime mover through a connecting rod, an airfilled space forming an air cushion being formed between the piston and the transverse wall and located in series with spring members interposed between the connecting rod and the driven member, the air space also being in communication with the atmosphere through a small bore when the piston and transverse wall are well spaced apart and isolated from the atmosphere by closing the small bore when the spacing is short so that air compressed in the space is utilized for transmitting the driving force to the impact body. As shown, a hollow cylinder 1 having a transverse wall 12 is slidable in a casing 3 and has slidably mounted within it a piston 10 connected by a gudgeon pin 17 and holder 16 to a connecting rod 9 driven by an electric motor. In operation, movement of the gudgeon pin holder 16 is transmitted to the piston through springs 19 and the air in the space 13 escapes through a small hole 14 in the cylinder but, after the piston closes the hole the air is compressed and the energy transmitted by the connecting rod is stored in the springs 19 and the compressed air, which energy is then transmitted to the cylinder which is accelerated and strikes a blow on a striker pin.

The cam is actuated by a knob 27 and is positioned by a spring detent 24 engageable with apertures or indentations 25 in the cam. The idler 4 is urged into engagement with the driving steps and the turn-table rim by a spring 18 and has an axially resilient, e.g. rubber, rim 17 so that the driving step may be moved past the idler without disengagement of the latter from the steps. In addition to ratio position, the knob 27 has a further, leftward, position, in which, by way of a member 15 and the projection 16 thereon, the idler is transversely moved out of engagement with the driving steps and turn-table rim. The motor comprises a two-pole laminated rectangular field magnet 30 having a wide arm with a cylindrical opening accommodating the rotor 1a and an opposite arm carrying an exciting coil. Each magnet pole is provided with a pair of shading rings. The rotor has a single squirrelcage winding and its shaft 3 is supported in selfadjusting spherical bearings 31.
