Patent GB-592139-A (GB)
Title: Improvements in and relating to pyrophoric lighters
IPC: F23Q2/02
Filed: 1945-05-22
Abstract: 592,139. Frictional igniters. DUNHILL, Ltd., A., and SMYTH, H. C. H. May 22, 1945, No. 12731. [Class 75 (iii)] The operating mechanism for a frictional lighter has means which, when released, moves freely to a predetermined extent under the action of a spring before striking a slotted member which actuates an abrasive wheel through a link or a rack and pinion mechanism. In a pocket lighter, a lever 18, Fig. 1, on the snuffer spindle 6 is actuated by a handle projecting through the side wall to move a spindle 12 on an arm 13 along an arcuate slot 11 in a wheel 10, until a spring 16 becomes effective. Then the spindle travels freely and gains momentum before striking the end wall of the slot to rotate the wheel 10 and so rotate the abrasive wheel 4 to which it is linked by an arm 8. According to the Provisional Specification, the snuffer 5 may be held by a catch and be spring-pressed, so that. when the catch is released, an abutment on the snuffer arm strikes a corresponding abutment on an arm pivoted to the spindle 6 at one end and to the link 8 at the other and a rapid rotation of the abrasive wheel 4 is effected. In a table lighter in the shape of a bugle, when the mouthpiece 22, Fig. 3, is depressed, a rod 49 is raised to engage a stud 33 and rotate a wheel 32 to which is pivoted a bar 44. When this bar passes the dead-centre position relative to a rod 45, a spring 47 becomes effective to rotate the wheel 32 rapidly so that a stud 34, Fig. 6, which moves freely between arms 42, 43 of a rack 40, strikes the arm 43 and causes the rack to slide forward and engage a toothed member 39 to rotate the abrasive wheel 37. The snuffer 30 which is fast on the spindle 29 of the wheel 32 and is raised when the wheel is rotated, may be closed by hand to set the lighter ready for use again, the toothed member 39 and the wheel 37 being provided with a one-way clutch coupling so that the abrasive wheel is not rotated when the rack 40 returns to its inoperative position. In a pistol-grip lighter, when the trigger 73, Fig. 7, is pulled, a bar 76 is moved forwardly against the action of a spring and a shoulder 78 carries a slide 66 forwards until a projection 68 of the slide engages the forward end of a slot in a bar 62 and carries this bar forwards. As the slide 66 moves through a guide slot in a wall 67, its upwardly curved rear end 70 is depressed and is freed from the shoulder 78, a stressed spring then pulling the slide 66 rearwardly with the projection 68 moving freely until it strikes the rear end of the slot in the bar 62. A rack on the bar 62 then rotates a wheel 60 to rotate the abrasive wheel 59, the wheels 59, 60 being provided with a one-way clutch coupling so that only rearward movement of the rack rotates the abrasive wheel.

Title: Control mechanism for preventing motor vehicles from creeping with provision for maintaining a constant restraining force
Inventor: CHANDLER IRVIN BARFIELD
IPC: B60T11/10
Filed: 1953-05-12
Abstract: 736,727. Electrically-actuated valves. MINNESOTA AUTOMOTIVE, Inc. May 12, 1953, No. 13295/53. Class 135. [Also in Groups XXXI, and XXXIV] In a brake control mechanism for use with hydraulic brake systems to prevent creeping of a motor vehicle, a solenoid-operated fluid control valve A is connected in the fluid supply line to the brake actuators of the rear wheel brakes 32 with the plug member 19 disposed towards said brake actuators, three switches 26, 27 and 28 respectively being interposed into the solenoid circuit to control the energization thereof and prevent back-flow of fluid therethrough. The switch 26 represents an ignition switch, the switch 27 is actuated by the accelerator pedal 29 and is closed when the accelerator pedal is released,' and switch 28 represents a manually-operated master-control switch which may be opened or closed by the operator. The control mechanism is operated only when both the ignition switch 26 and the master switch 28 are closed. Then, whenever the accelerator pedal 29 is completely released, the solenoid 24 is energized. This produces a magnetic field and magnetizes the core member 11, which attracts the ferrous metal valve carrying body 20 to project said body forwardly to engage the divided-annular ring 23 against the face of partition 1'2 on the inlet side thereof and compress the spring. 22. With the body 20 in its projected position and the valve 21 seated against seat 15 fluid is still'permitted to. flow to the brake actuators through passages 20a, 20b, 20c, and outwardly from inner valve, chamber 9 through passages 13, past the spring-loaded oneway annular check valve 16, and into the fluid supply lines. When the brake pedal 30, which operates a conventional master cylinder 31, is released and fluid seeks to return, the annular cheek valve 16 seats itself to close off passages 13 and the only open passage permitting backflow of fluid is the central seated flow-passage 14. The spring-loaded valve 21 directly opposes back-flow of fluid through seated flow passage 14, as indicated in Fig. 1, and thereby maintains a precisely predetermined residual pressure in the fluid supply line and holds the brakes in the applied position with a predetermined foree. Immediately upon de-energization of the solenoid 24, as by stepping on the accelerator pedal 29, the body 20 is permitted to move rearwardly into its retracted position, as shown in Fig. 2, and releases the compression from spring 22 and the pressure in the brake line, the valve 21 being moved away from the seat 15 by the back-flow of fluid pressure to permit unrestricted flow of fluid back to the master cylinder 31.

[Class 83 (iii)] In a dividing-head for the work spindle 40 of a milling &c. machine, particularly for cutting gears, the drive of the dividing-plate 4 for the purpose of differential dividing is taken from the dividing-shaft 2 through a transmission gear, the axes of the elements of which also occupy fixed positions. As shown, the dividing-plate 4 which is loose upon the dividing-shaft 2, is geared to a shaft 10 coupled by change gears to a parallel shaft 8 driven directly by a gear 6 on the shaft 2. For simple dividing, the change wheels are removed. The shaft 2 is operatively connected to the work spindle 40 through a planetary gear comprising a sun wheel 19 fixed to a shaft and a planet wheel 20 carried by an arm 22 fixed to a shaft 33 connected by gearing 34 ... 39 to the spindle 40. The annular member 24 of the planetary gear is loose on the shaft 2 and geared to a shaft 27 which, when it is desired to effect spiral milling, is connected by change wheels to the feed screw of the milling-machine. When these change wheels are removed the member 24 may be located by a pin 43. The spindle 40 and its driving gears are carried by a frame 41 angularly adjustable about the shaft 33 for milling bevel gears. In a simpler form of head which, however, does not permit of differential dividing with spiral milling, the planetary gear is omitted, the shafts 2, 33 being replaced by a single shaft and the shaft 10 bemg connectable by change gears to the feed screw of the machine.
