Abstract: 1468612 Automatic choke valves BRIGGS & STRATTON CORP 17 June 1974 [19 Nov 1973] 26775/74 Heading F1H [Also in Division G1] In an I.C. engine, a choke valve 15, Fig. 2, is biased towards the closed position by a weighted lever 20 and is urged towards the open position as the engine speed increases by means of a vane 21 which is acted on by the stream of air from the engine cooling blower 6. The vane 21 is carried by a hub 24 which is freely journalled on a spindle 22, and operates the choke valve 15 via linkage 25, 26, 19. The spindle 22 is journalled in a bearing boss 23 and has a transverse slit 32, Figs. 2, 8, 9, engaged by the inner ends of a pair of bi-metallic coils 33, 34. The coils are oppositely wound, have their higher coefficients of expansion at opposite faces and have their free outer ends abutting oppositely-disposed shoulders 39, 39'. When the engine is cold, the coil 34 reacts against shoulder 39' and turns the spindle 22 into a position in which one end of an arcuate slot 46 in a collar 47 fixed to the spindle abuts a stop 48, and one end of an arcuate slot 44 in a further collar 43 fixed to the spindle then coacts with a projection 28 on the vane 21 to limit the extent to which the vane can move to open the choke valve 15. Meanwhile the coil 33 is out of contact with the shoulder 39 and therefore inoperative. When the engine is hot, the coil 34 is out of contact with the shoulder 39' and inoperative while the coil 33 now reacts against shoulder 39 to turn the spindle 22 to the position in which the opposite end of the arcuate slot 46 abuts the stop 48 and the opposite end of the arcuate slot 44 coacts with the projection 28 to hold the choke valve 15 slightly open when the engine is stationary and to allow the choke valve to be fully opened by the vane 21 when the engine begins to run.
Patent GB-715339-A (GB)
Title: Improvements in and relating to laundry folding machines
Inventor: BOAM HARRY
IPC: D06F89/00
Filed: 1951-11-15
Abstract: 715,339. Folding fabrics. MANLOVE, ALLIOTT & CO., Ltd. Nov. 25, 1952 [Nov. 15, 1951], No. 26816/51. Class 42 (2) Relates to laundry installations wherein articles pass direct from an ironer to a folding machine of the kind in which the leading edge of the article is lifted while the remainder of the article travels on beneath ; a timing device provides a delay between actuation of detecting means by the leading edge of an article and the raising of the lifting means, and a different delay between the re-setting of the detecting means by the trailing edge of the article and the lowering of the lifting means, the duration of the " lifting " delay being automatically dependent upon the speed of the ironer and the duration of the " dropping " delay being either automatically dependent upon the speed of the folding conveyer or alternatively predetermined in accordance with a selected speed of the conveyer. As shown, closure of a switch by the leading edge of an article causes a solenoid 32 to be energized and thereby move an arm 54 to the left. This movement causes a lever 56 to move about a pivot 58 so as to (a) displace a shaft 40 axially to the left and bring a timing disc 42 into driving engagement with a clutch plate 38 continuously driven from a shaft 34 coupled to the shaft of the ironing machine, and (b) displace a rod 62 to the right so as to bring the part 60a of a pawl 60 to bear against the edge of disc 42 and thereby raise the pawl sufficiently to open a switch 64. Disc 42 is manually pre-set through a friction wheel 48 and wheels 50, 52 so that a peripheral notch 42a is displaced from pawl 60 through an angle which is proportional to the distance between the switch and the lifting means ; friction wheel 48 is loosely mounted on shaft 40 but is tied thereto by a spring 46. When disc 42 has rotated through its angle of prior displacement, pawl 60 enters notch 42a and closes switch 64 which causes a lifting relay to be energized; this. has the effect of energizing a lifting solenoid, and also de-energizing solenoid 32 so that pawl 60 moves back to its original position, clutch 38, 42 is disengaged, and disc 42 moves back to its original position under the action of spring 46. When the trailing edge of the article passes the switch the latter opens and thereby deenergizes the lifting solenoid and energizes a dropping solenoid which is slugged to maintain the leading edge lifted until the trailing edge of the article is beneath it. The delay imposed by the dropping solenoid is fixed for a given speed of the folding conveyer; where the conveyer speed is variable, a relay may be used which gives automatically a time delay dependent upon the conveyer speed. Specification 651,340 is referred to.
