IPC: F02D1/00
Filed: 1937-07-19
Abstract: 502,723. Speed governors; fuel-injection pumps. BOSCH AKT.-GES., R. July 19, 1937, No. 19901. Convention date, July 18, 1936. [Class 57] [Also in Group XXVIII] A fuel-injection pump has a plunger provided with a conical end 14 and inclined edge 11 which co-operate with suction and return passages 6, 7. As the speed of the pump increases, the edge 14 causes increased throttling of the spill and delivery commences earlier in the stroke thus advancing the time of injection. The end of the piston may be flat and co-operate with passages in the cylinder which produce this throttling effect. The control rack 16 of the pump is controlled by a spring-loaded diaphragm 19 exposed to pressure in the induction pipe 22 between the valve 23 and the engine. In the full load speed range, movement of rack 16 is opposed by a further spring 26 which limits the fuel delivery to remove smoke in the engine exhaust. Specification 491,068 is referred to.

Title: Road maintenance device
IPC: E01C19/21
Filed: 1963-05-20
Abstract: 1,031,198. Road surfacing apparatus. H. A. CARTWRIGHT. May 20, 1963, No. 20023/63. Headings E1G and E1T. Road surfacing apparatus comprises a wheeled frame 12 carrying a spraying means 27 for bituminous or like materials and means for spreading aggregate, means 68 carried on the frame for movement into and out of engagement with the road surface controlling the operation of the bitumen and aggregate discharge means. The frame 12 is supported on two rear wheels 15 and a steering front wheel 17 connected by a tow bar 13 with a towing tipping aggregate truck B. Aggregate is received by a hopper 11 and passes past a screw type agitator and spreader 50 to flow controlling baffle 55 leading to a spreader paddle 58 which discharges through an opening 57 to the road surface. Bitumen from a tank truck T is fed to a tank 10 having a heating burner 20 and a three-way discharge valve 36. The valve 36 is connected by a pump 24 and filter ST to a spraying device 28 under the control of an airservo 39, further three-way valves 30, 31 being provided to allow bitumen circulation through the spray assembly 28, return of excess to the tank and emptying of the system on completion of operation. A tilting axle 69 carried on a pivot 70 on the frame 12 has a first wheel 72 urged into road engagement by a second air servo 86, against the action of a spring 84, to drive the spreaders 50 and 58 through chains 67, 65. With the axle tilted to engage the wheel 72 a valve 92 is opened by linkwork 94 to admit air to the servo 39 and allow bitumen spraying. At the completion of spraying a handle 102 is moved to shut air valve 98 supplying servo 86 and the wheel 72 is lifted stopping drive to the aggregate spreading mechanism and shutting off the bitumen spray by valve 92. As the axle tilts, a wheel 78 contacts the road and screws itself along a threaded end of the axle, at the same time a latch 110 moves towards the inner end of the axle to shut the air valve 97. On resumption of work, the wheeled frame is moved backwards beyond the end of the surfacing, screwing the wheel 78 to the end of the thread. The frame is then towed forwards allowing the wheel 78 to move in the opposite direction until, as the joint is reached, a projection 83 on the wheel trips the latch 110 which moves under spring 111 to open the air valve 97 causing tilting of the axle to engage the aggregate spreader drive wheel 72 with the road and to admit air by valve 92 to commence the bitumen spraying. The apparatus thus providing even distribution of bitumen and aggregate over the joint as well as during normal operation.

Title: Door latching mechanism
IPC: E05B65/32
Filed: 1964-05-14
Abstract: 1,035,636. Latching mechanisms. J. H ROETHEL. May 14, 1964 [Sept. 3, 1963], No. 20086/64. Heading E2A. A door latching mechanism comprises a plate 11, a pair of spaced pivot pins 17, 18 mounted on the plate for independent angular movement relative thereto, a pair of latch jaws 19, 20, Fig. 6, mounted on the pins 17, 18 respectively and disposed on one side of the plate 11, the jaws being adapted to be engaged by a keeper 22 and rotated thereby to a latching keeper-retaining position, a pair of abutment members 25, 24 carried by the pins 18, 17 respectively, Fig. 2, having abutment faces 25a, 24a respectively, stop means 37, 31 movably mounted on the plate 11 and movable into engagement with the abutment faces when the jaws 20, 19 occupies their latching positions so as to hold the jaws in those positions, and means for releasing the stop means from engagement with the abutment faces to permit the jaws to be moved from their latching positions. In the embodiment shown one of the stop means is a lever 37 pivotally mounted on the plate 11 and spring-urged into contact with the abutment member 25. The means for releasing this stop means is a link 34 pivoted to a bell-crank lever 29 pivoted to the plate 11, the link 34 having an abutment face 34b for engagement with an upturned lug 37b on the lever 37. The lever 29 has riveted thereto the stop means 31 in the form of a pawl for engagement with the abutment face 24a of the abutment member 24. In use the jaws 19, 20, which are spring-urged to the releasing position, are engaged by the keeper 22 to turn the pins 17, 18 anti-clockwise and clockwise respectively. The initial rotation of the pin 17 allows the pawl 31 to fall behind and engage the abutment face 24a so that the mechanism is held in a safety latching position. Further rotation of the pins allows the lever 37 to fall so that a face 37a thereof engages the abutment face 25a to put the mechanism in a fully latching position. To release the mechanism the lever 29 is rotated clockwise, either by depressing a push-button 33, or by actuating a handle which brings a lever 41 into contact with a face 34a on the link 34 to lift the link, rotation of the lever 29 thus freeing the jaw 19 by raising the pawl 31, and lifting of the link 34 and hence the lever 37 freeing the jaw 20. To lock the keeper in the latching position a lever 42 is depressed to disengage the link 34 from the lug 37b and thus render subsequent raising of the link ineffective. In alternative embodiments the lever 42 is actuated by a button operated lever, or by a linkage connected to a key operable device, or by a linkage connected to a handle which also actuates the lever 41.
