Title: Improvements in charging skip shaker mechanism in concrete mixers or other apparatus
IPC: B28C7/08
Filed: 1948-03-31
Abstract: 655,112. Loading-skips. THORNTON, A.A. (Kwik-Mix Co.). March 31, 1948, No. 9097. [Class 78 (i)] [Also in Group II] A loading-skip is provided with a shaker mechanism which operates to assist the discharging of the contents only after the skip has been lightened by the discharge of the greater part thereof. Shown as applied to a concrete mixer, a skip or hopper 1 mounted on a shaft 3 is pivoted, for discharging the contents, in vertical slots in a bracket 6 on a frame 2. A roller 8 on a rocker arm 7 is vertically reciprocated by a cam 9 and a tip 12a engages the pivot bar 3 at 13. The arm 7 has a pin 11 entering a slot 14 in a box bracket 12, and pivoted to the pin 11 is a toggle lever arrangement 15, 16 urged to straighten by a spring 21 on a rod 19. When fully loaded the weight of the skip breaks the toggle, as shown, so that the pin 11 is free in the slot 14 and the arm 7 pivots about the tip 12a but, as the load is discharged, the spring 21 overcomes the weight of the skip and straightens the levers 15, 16, forcing the pin 11 to the tip of the slot 14. The arm 7 then pivots about the pin 11 and the tip 12a engages the point 13 and reciprocates the skip vertically in the bearing bracket 6 to assist the final discharge of the contents.

Title: Improvements in or relating to cathode-ray tube display systems
IPC: G01S7/06
Filed: 1947-04-03
Abstract: 657,047. Cathode-ray tubes. HANSFORD, R. F., and SPERRY GYROSCOPE CO., Ltd. April 3, 1947, No. 9182. [Class 39 (i)] A display system includes a cathode-ray tube which has an optically clear window 3, Fig. 1, in the bulbous portion of the envelope and close to the electron gun side tube, and the image on the fluorescent display screen 7 produced by the electron beam has superposed thereon a real image of an external field which is projected through window 3 by an optical projection system 4, 6. In one form, Fig. 1, a photographic film or lantern slide 5 is illuminated by source 6 and the image is focused by lens 4 on to the display screen 7. The image on the film may be a map or chart. A condenser lens (not shown) may be interposed between 5 and 6. Lens 4 is non-parallel to film 5 and screen 7 so as to compromise between distortion and sharp definition of the image projected on to screen 7. In a modification, Fig. 2 (not shown), light reflected by a map or chart is subsequently reflected by a mirror and focused on to screen 7. The mirror is so arranged as to minimize distortion of the image projected on to screen 7. The mirror may be replaced by a totally internally reflecting prism. The tube construction may be as in Fig. 3; window 3 is a flat polished glass plate and is sealed to a side tube 2 at 11. The side tube 2 is then sealed to envelope 1 at 12, and finally tube 13 is sealed to envelope 1 at 14. In a modification, Fig. 4 (not shown), the tube 13 is sealed to envelope 1, side tube 2 is then sealed to envelope 1, and finally a thimbleshaped window of thin glass is sealed to side tube 2. In the latter case lens 4, Fig. 1, may be located within the thimble. Instead of the window 3 being sealed to a side tube 2 it may be sealed direct to envelope 1. The window 3 may form part of the focusing lens.  The Provisional Specification states that optical compensating means may be disposed in the optical path to correct distortion of the projected image due to the axis of projection not being normal to the display screen and refers in addition to a form using a semitransparent mirror, so that images of both a film and a map may be simultaneously projected on the viewing screen of the cathode-ray tube.

Filed: 1943-06-10
Abstract: 581,406. Coin-freed apparatus for hiring typewriters. GRAHAM, J. B. June 10, 1943, No.9359. [Class 27] Coin-freed mechanism permitting a typewriter to be used for a definite time after a coin has been inserted comprises a lever 11 adapted to lock a control bar A of the typewriter so as to prevent the use of the latter, the lever being moved out of engagement with the bar by a spring 11c when a coin is inserted and being moved back again to lock the bar by ratchet gearing 5, 6, 7 and a clockwork device. In the construction shown the coin-freed mechanism and the lever 11 are mounted in a casing 3 fixed within a box 1 having a lid 1a secured by a lock 2, the typewriter being secured to the lid by screws 1c so that it cannot be removed unless the lid is unlocked. Normally the bar A is locked by the lever 11, the latter being locked by a hook 12f on a lever 12 pivoted at 12c and controlled by a spring 12h. When a coin is inserted and a coin slide 14 is pushed in, (1) a lever 13 is rocked by springs 13d connected to the lever and the slide, and this lever rocks the lever 12 from H to J so that the lever 11 is now locked by a hook 12g instead of 12f, the lever 11 being kept in place during the rocking of the lever 12 by the end 10d of a lever 10 controlled by a spring 10c, and (2) a shoulder 14c on the slide 14 engages a pin 8b on a lever 8 and rocks the latter to tension a spring 8a. The end 8c of the lever 8 lifts the lever 10 from position F to that shown in full lines, the lever 10 being then locked by a pin 10a engaging in a notch 9d in an arm 9. The coin slide is now released and is retracted by its spring 14d, and rocks the lever 13 again thereby rocking lever 12 so that the lever 11 is released from the hook 12g and frees the typewriter for use. The spring 8a slowly returns the lever 8 to its original position at a rate determined by clockwork 4, the lever 8 having pawls 6, 7 engaging a ratchet wheel 5 driving the clockwork train. As the lever 8 returns the pin 8b finally bears on a curved face of the arm 9 and rocks the latter thereby releasing the pin 10a and allowing the lever 10 to be rocked by its spring 10c to move back the lever 11 into its locking position in which it is again held by the hook 12f..

Abstract: 591,729. Locking rods. TRICO PRODUCTS CORPORATION. April 19, 1945, No. 9875. Convention date, May 23, 1944. [Class 80(iii)] [Also in Groups X and XXVIII] In the fluid-pressure operating mechanism for a vertically sliding window of the type wherein limited play is allowed between a fluid operable member of the motor and means connecting it to the window, whereby a window-imparted force operates means connected to a lock shoe carried by the member to lock the shoe against a fixed part, and thereby lock the window, chattering is prevented by the provision of resilient means, independent of the locking means, maintaining the shoe against the fixed part with a force just sufficient to prevent over-running, and consequent locking of the shoe by the weight of the window, when the motor is operating. Fig. 2 shows a U-spring 26 which acts directly on the locking shoes 20 of the servomotor of a vehicle window operator similar to that described in Specification 565,137, with a force sufficient to cause the shoes to drag on the fixed rods 16 whereby they are prevented from over-running the steady travel of the piston section 12 to the,right, during window opening. Spring-loading of the toggles 21 is thus unnecessary, and the drag of the shoes 20 eliminates the need for counter-balancing the window. The single expanding U-spring 26 may be replaced by two contracting U-springs each urging a shoe towards the wall of the housing 18, and the shoe-engaging ends of the spring or springs may enter the housing 18 through holes 29.
