Abstract: 461,355. Interrupters ; contacts. SPERRY GYROSCOPE CO., Ltd., and NISBET, R. H. July 15, 1935, No. 20209. [Class 38 (v)] In a contact mechanism particularly for use in a transmitter for transmitting indications of angular movements such as those of a gyro-compass, a cam 9 cooperates with contact springs 2, 3 which are pliant and have a large bias ; i.e., the springs in their mounted position have been moved a considerable distance from their unbiassed position. The blade 3 is held back by an adjustable stop and there is also a stiffer spring 1, the position of which is determined by a stop 10. The cam 9 engages a roller 8 on the spring contact 2 and causes a contact 5 on the spring 2 to leave a contact 4 on the spring 1 and a contact 6 to engage a contact 7. Three of these cams are adapted to be mounted on a common shaft driven through a steel blade or wire coupling adapted to suppress high frequency oscillations.

Title: Improvements in or relating to apparatus for printing late news in newspaper printing machines
IPC: B41F13/46
Filed: 1921-07-28
Abstract: 184,987. Linotype & Machinery, Ltd., and Goulding B. J. J. July 28, 1921. Late news, means for printing; tripping-arrangements.- In a late-news printing-apparatus comprising two fudge heads adapted to coact alternately with an impression cylinder so that one fudge head is printing while the other is inoperative, the printing relationship between the fudge heads and impression cylinder is made and broken by moving both fudge heads simultaneously with respect to the impression cylinder, or by moving the impression cylinder relatively to the fudge heads. In the form shown in Figs. 1 and 3, the fudge heads 8, 9 are mounted on shafts 7 carried by a two-armed lever 6 fixed to a rockshaft 5 operated by the axial movement of a cam 3 on the shaft 1 of the impression cylinder 2, the cam having high and low tracts 3b, 3<a> alternately engaged by rollers 10<a>, 10<b> on a two-armed lever 10 fixed to the shaft 5. Pinions 12, 13 loose on the shafts 7 engage a driving gear 14 on the shaft 1 and have integral friction-clutch parts 15, 16, the coacting clutch parts 15a, 16a being formed on sleeves 15<b>, 16<b>, slidiably keyed on the shafts 7, and provided with friction discs 17, 18 co-operating with similar discs 17a, 18a on shafts 17<b>, 18b carrying pinions 17<c>, 18<c> engaging a gear 21 on the shaft of a motor 22. The clutch parts 15, 15a and 16, 16<a> can engage in only one position determined by spring-pressed bolts 15<c>, 16<e> in the parts 15<a>, 16a and holes 12<a>, 13a in the parts 15, 16. To change over the printing from one head to the other, for instance from the head 8 to the head 9, the motor 22 is started, and, through the discs 18a, 18, drives the shaft 7 of the head 9. When the speed of this shaft approximates to that of the pinion 13, the clutch lever 20 is operated to separate the discs 18a, 18 and to move the bolt 16<c> into engagement with the hole 13<a> and to close the clutch 16, 16a. The cam 3 is then operated to rock the shaft 5 to move the head 9 into and the head 8 out of printing relationship with the cylinder 1, and the clutch lever 19 operated to stop the head 8. In the form shown in Fig. 5, the impression cylinder 2 is movable relatively to the fudge heads 8, 9, and for this purpose is mounted in eccentric bearings 26 operated by lever arms 27, 28, 29 and links 30, 31. The arm 28 is provided with an operating-handle 34 and moves between stops 35, 36. In the extreme positions of the arm 28, the arms 28, 29 and links 30, 31 form toggles to lock the bearings of the cylinder 1.

Breech actions, sliding breech-block.-A rifle of the kind having a tubular magazine beneath the barrel and a feed lever or lifter adapted to receive a cartridge from the magazine and to lift it into line with the barrel, has a breech-block comprising two relatively slidable parts both of which support the base of the cartridge, one part, which advances before the other, being at the front sufficiently narrow to pass through a slot in the cartridge lifter to ram the cartridge into the chamber, the other part then advancing to complete the support of the base of the cartridge and also preferably to act as a firing-pin. As shown in Figs. 3, 13 the breech-block comprises an inner part 4 and an outer part 5 both pressed forwards by springs. The cartridge lifter comprises a lever 10 formed at the front end with a recess 10<a> to receive the cartridge. The rear wall of the recess is formed with a slot, through which the front end of the inner part 4 of the breechblock passes to ram the cartridge into the chamber. The other part 5 is held by a sear 13 and at the front is formed with a firing pin 5<a>. The cartridge lifter is reciprocated by shoulders 4<a>, 4b on the part 4 engaging the rear end 10<c> of the lever. In a modification, the breech-block mechanism is mounted on a removable cover 1<a>, which is locked in place by a sliding bolt 14. A vertically sliding bolt 15 retains the breechblock in the cover when this is removed. The breech-block may be provided with a pivoted locking lever 16, Fig. 10.

Abstract: 204,814. Jennings, J. T. July 28, 1922. Spray carburettors. - A single throttle valve controls a main and a supplementary outlet, the supplementary outlet being in connection with a separate heaver whereby the supply of heat to the mixture may be varied from a maximum at small throttle openings to a minimum, or none at all, at full opening. A barrel throttle valve 1, Fig. 1, controls the main passage 6 and has a port 3 which places the interior 5 of the throttle in communication with a port 4, leading to the heater, as the throttle begins to open the port 6. The port 4 closes when the throttle is about half open. In a modification, the port 4 begins to open before the main passage. The heated portion of the mixture may pass to the induction pipe or be returned to the throttle valve. In Fig. 3, a sliding throttle 14 has a passage 15 which opens to a port 16 leading to the heater before the main port 18 opens. In Fig. 4, the casing has an additional port 20 and the throttle is recessed at 21 to receive the mixture which passes to the heater by port 19. In further modifications, (1) two ports lead to the heater and (2) a butterfly throttle valve is employed. The heater is a separate structure heated bv the exhaust or the cooling water and preferably has a small heating passage giving a high velocity of flow. Some heat may be imparted to the mixture at large throttle openings.

Abstract: 298,317. Baker Perkins, Ltd., Harber, L. S., and Pointon, J. E. Aug. 9, 1927. Driving-mechanism.-Variable speed gearing is provided with control means whereby the driven machine, on starting, is driven for a predetermined period at a varying speed, then for a second predetermined period at a constant speed after which the prime mover is automatically stopped. The gearing is shown as applied to a kneading-machine driven by an electric motor through adjustable cone pulleys d, e, Fig. 5 which are mounted on rocking arms o, p. The arms are operated to vary the gear ratio by means of a screwed shaft k which engages nuts on the arms and is driven through worm gearing j from a shaft i driven in turn from the driving shaft g. The screwed shaft k is fitted with fixed and adjustable stops x, y, operates an indicator u, and is driven through a clutch l which slips when the arms have been rocked to their limiting position. The arms are re-set by rotating the shaft k by a handle t. The motor is controlled by a spring-influenced switch operated by a. cable 2, Figs. 6 and 7, and wound on a drum 6 loosely mounted on the shaft 5 of a starting handle 1. The drum is rotated to operate the switch by means of an arm 21 on the shaft 5 engaging a projection 7 on the drum. The drum is held in the " on " position by the engagement of a pivoted catch 8 with the projection 7, the catch being released after a predetermined number of revolutions of the machine to stop the motor by means of a pin 9 on one member 10 of a slipping clutch driven through worm gearing 13, 15 from the shaft i. The angular setting of the pin 9 can be varied to alter the period of operation of the machine by means of a setting device 16, and the member 10 is re-set on starting the machine by means of a gear 11 thereon engaging a gear 17 on the shaft of the starting handle, the gear 17 having a pin 19 engaging an adjustable stop. The machine can be independently stopped by operating the catch 8 by a hand-operated cam 24.
