Filed: 1935-05-04
Abstract: 442,338. Average-indicating instruments. UHER, E., 60, Wotanstrasse, Munich, Germany. May 4, 1935, No. 13377. Conven. tion date, May 5, 1934. [Classes 106 (i), 106 (iii), and 106 (iv)] In apparatus for indicating average rates, for example the average speed of a vehicle, wherein two contacts 4, 5 are moved along resistances 2, 6 distances corresponding respectively to the distance travelled by the vehicle and to the time taken, and wherein the electric circuit is arranged as shown so that a current measuring instrument 7 gives an indication of the average speed, the contact devices have pointers working on scales calibrated in terms of the two variables. The circuit includes a steadying resistance 3 of the iron-hydrogen type. The resistance wire 2 is coiled in a helical groove on a stationary drum 9, while the resistance wire 6 is wound on a stationary ring 10. Clockwork 11 rotates a shaft 12 moving a contact arm 14 upon the ring 10, and the roadwheel of the vehicle is geared to drive frictionally a contact arm 21, 22, along the drum 9, according to the distance travelled. Moving with the two contact arms are pointers 24, 27 indicating distance and time on their respective dials. For setting the apparatus to zero, a button 28 is depressed to couple sleeves 26, 18, so that by turning the button both contact arms 21, 14 are moved. When the arm 21 has been set at zero, the button 28 is pulled out, disengaging the locking springs 17, and is rotated to set the arm 14. Specifications 351,413 and 392,207 are referred to. The Specification as open to inspection under Sect. 91 comprises also a method of using the apparatus in order to calculate in advance a requisite average speed, the pointers 24, 27 being set at selected values on their scales, and the instrument 7 read to ascertain the quotient of these values.

Title: Improvements in or relating to bolt making machines
IPC: B21J13/08
Filed: 1934-05-03
Abstract: 426,845. Forging bolts. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(National Machinery Co. ; Tiffin, Ohio, U.S.A.) May 3, 1934, No. 13393. [Class 83 (iv)] In bolt - making machines, the blanks are transferred from one pair of dies to another by a pair or pairs of gripping fingers simultaneously and oppositely operated. The fingers are pivotally mounted on a reciprocating carriage or slide. Slight independent movement of each set of fingers relatively to the rest, may be allowed in the closed position to accommodate irregularities. The transfer mechanism is pivoted so as to be capable of being swung to one side to permit access to the tools. Relief mechanism is provided to act automatically when an obstruction occurs. As shown, wire or rod stock is cut off by an arm 16, which is oscillated about pivot 17, Fig. 3, by means of a cam 18, and roller 19 to bring the work to a die 11, from which it is successively taken by transferring - grippers 51 to dies 12 and 13. The grippers are mounted on a carriage 32, reciprocated by a cam 68, roller r, links 69, 71, rack 72, gear wheel 73, shaft 74, releasable coupling 87<1>, shaft 76, crank 77 and adjustable connecting-rod 78. The fingers of the grippers 51 are all simultaneously opened against the action of springs 56, 57. A cam 58 transmits motion to a roller 59, push rod 60, lever 61 and shaft 23, Fig. 6. The shaft 23 carries a sleeve 62, having a projection 63 engaging one end of a lever 65 on a sleeve 64 carried by a shaft 28. The other end of the lever 65 contacts with a roller 67 on an arm 66 attached to a pivot pin 39. This pin carries a gear wheel meshing with corresponding gear wheels on adjacent pins 38, 40 the gear wheel on the pin 40 meshing with a corresponding gear on a pin 41, thereby providing for simultaneously movement of all the gripper fingers. To provide for slight relative movement to overcome irregularities in the work or for similar reasons, the gear teeth which mesh when the fingers are closed are formed with narrower teeth. Other arrangements for the same purpose may bo employed such as differential gear teeth or teeth of differing pitches. Any resistance to the reciprocation of the carriage 32, as by a distorted blank, or broken knock out pin, merely results in sliding one pail of the coupling 87<1> against the action of a spring 88 to release the engagement of a tongue thereon engaging a notch.

Filed: 1927-05-20
Abstract: 272,473. American Multigraph Co., (Assignees of Schultz, A. L.). June 14, 1926, [Convention date]. Rotary machines; addressing-machines; tripping and throw-out arrangements.-In a rotary office printing-machine comprising a cylinder 10, Fig. 2, carrying a flexible forme 30 and an exchargeable address-plate 42 both of which coact with an impression roller 14 to print an addressed letter through an ink-ribbon 35, while the address-plate also coacts with a segmental part 50 of a roller 51 to print an address on an envelope, the roller 51 is arranged to make one revolution for each rotation of and at the same peripheral speed as the cylinder 10. The roller 51 is coupled to a disc 61, Figs. 4 and 6, which is rotated by a gear 60 through a pawl 62 having a hook 65 engaging behind a shoulder on the disc. The gear 60 is rotated from the drum 10 by gearing and itself drives a gear 81 carrying a cam 80, which engages the tail end of the pawl 62 to free the disc 61, the ratio of the gear 60 to the gear 81 being a whole number plus a fraction the numerator of which is unity and the denominator the ratio of the gear on the drum to the gear 60, so that the pawl 62 is released from the disc 61 to allow the gear 60 to make one or more idle revolutions and connects the disc to the gear for one revolution once per revolution of the cylinder 10. A disc 91 spring-pressed against the end of the roller 51 acts as a brake to stop the roller as soon as it is freed. The roller 51 is rotated from the disc 61 through an Oldham coupling 66, and, for adjusting the impression, it is mounted on an eccentric shaft 53 adapted to be turned by a lever 57. The envelopes are placed one at a time in a pocket consisting of plates 110, 111, Fig. 2, the former having a part 118, which directs each letter as it is ejected after printing so that it passes over the plate 111 and falls into a receptacle or on to the printed letter. The addressplate 42 is pushed by hand into a channel 40, 41 against the action of a spring, a catch springs up to engage the outer edge of the plate to hold it in place, and the catch is released by hand after printing to allow the spring to eject the plate into a position where it can readily be grasped and removed.

Title: Improvements in or relating to a vehicle door locking system
Inventor: OISHEI JOHN R
IPC: E05B65/38
Filed: 1961-04-14
Abstract: 979,343. Remotely controlled fastenings; latches. TRICO PRODUCTS CORPORATION. April 14, 1961, No. 13637/61. Heading E2A. The reduced pressure existing in the manifold 12 of a motor vehicle engine is used to operate actuators 26 for locking each door of the vehicle. A single conduit 28 associated with each actuator connects it to a conduit system which is connected to the manifold and also includes a pump 16 whereby an increased pressure is passed through the conduits to unlock the doors. A valve 31 included in the conduit isolates the actuators from the manifold when the driver's seat is unoccupied. When the engine is started a reduced pressure in the nipple 15 (Fig. 2) draws the diaphragm 18 downwardly to open valve 20 whereby the reduced pressure is applied through nipple 23, conduits 32, 30 (assuring the valve 31 is open), 29, 28 to diaphragms 33 of the actuators 26. The rod 74 (Figs. 5 and 6) is thus drawn downwardly to pivot levers 60, 63 into the locking position shown where these levers are held in position by the spring 71. In the locking position the lever 63 holds a lever 69 operatively connected to a push button 76<SP>1</SP> out of engagement with a crank 55, which, when moved, engages lever 83 to release a ratchet associated with a rotating bolt. A sill rod 58 also operates lever 60 as above described to lock the door. The two sides of diaphragm 18 are connected by conduits 137, 138 and a metering filter 139 to allow the pressures on either side of the diaphragm to gradually equalise thus allowing the valve 20 to close whereby the pressure in the conduit system and actuators is returned to atmospheric by leakage through conduits 41, 38 and metering filter 37 in the pump 16 if the valve 31 is open, and through a metering filter in this valve if it is closed. To unlock the doors the foot-operated piston 39 of the pump 16 is depressed, and the valve 51 opens to supply pressure through the nipple 23 and conduits to the actuators 26, thus raising the rod 74 to move lever 63 out of engagement with lever 69. In a modification the door locking mechanism is controlled manually by a push button which connects a vacuum tank, supplied from the engine manifold, with the actuators. The diaphragm 18 and associated chambers are then omitted from the pump.

Abstract: 958,159. Thermocouples. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. March 26, 1963 [April 9, 1962], No. 13651/62. Heading H1K. A method of producing a completely sealed and insulated thermocouple junction at one end of a fine thermocouple cable, comprising a cable sheath, comprises the consecutive steps of baring the thermocouple leads of their insulation within the cable sheath at one end of the cable, cropping the bared leads within the sheath, welding the cropped leads in an inert atmosphere by discharge of electrical energy through the leads, to form the thermocouple junction, packing insulation around the junction within the sheath, ramming a cylindrical plug of uniform diameter into the open end of the sheath so that the insulation within the sheath is compacted, and arc-welding the plug to the cable sheath in an inert atmosphere so that the j unction is sealed in a leak-tight manner. In a described embodiment the thermocouple cable comprises a sheath of stainless steel containing two thermocouple leads of chromel and alumel, separated by magnesia insulation. The magnesia is removed from within the sheath to a depth of #-inch by means of a fine tube (which may be a modified hypodermic needle) which is slid over the free ends of the leads into the open end of the sheath and rotated to remove the magnesia and twist the leads into a junction, further twisting breaking the leads off at the junction. The junction is welded by discharging a capacitor through the junction in an argon atmosphere. Dried course grain magnesia is packed into the open end of the sheath around the junction and a stainless steel plug is slid into the open end to compress the magnesia. The plug is then electric-welded to the sheath and the weld cleaned in an acid bath.
