Title: Improvements in or relating to advertising devices
IPC: G09F23/02
Filed: 1925-09-17
Abstract: 262,198. Turton, J. G., and Matthewman, W. Sept. 17, 1925. Reel and endless web apparatus; endless chain and like carriers, apparatus with; forms and models with characteristic movements; actuating. -A strap-hanging device for the use of persons in vehicles, theatre queues, &c. is combined with a moving advertisment actuated by the pull on the strap. One or more straps 24 pass through slots 26 in a casing 1 and are attached to flanged sleeves 13 mounted on and operating a shaft 11 by pawl and ratchet wheel 22. A spring connecting the casing and a pulley 16 on the sleeve 13 retracts the strap, a downward pull on which rotates the shaft 11, and through gearing 10, 9 rotates a drum 4. An endless band bearing advertisements which may be detachable passes round the drum 4 and an idle drum 3, and is viewed at a window in the casing 1. The drums 3, 4 may be adjustable apart, and have upper bearings 7 which permit of their removal. Stops 28, 29 on the strap 24 and on a flange 15 of the sleeve 13 limit the movement of the strap. The stops 28, 29 may actuate switches which light up lamps 31 within the casing. The shaft 11 may be extended or connected by flexible shafting to a distant sign. Other mechanism for actuating moving sign parts may be employed, and the casing 1 may contain separate signs each operated by a strap 24.

Title: Improvements in or relating to harvesters
Inventor: FISCHER RAYMOND C
IPC: A01D43/08
Filed: 1960-07-04
Abstract: 888,676. Forage harvesters. INTERNATIONAL HARVESTER CO. July 4, 1960, No. 23259/60. Class 6(3). In a forage-harvester of the kind having knives 36 on a transverse rotor 35 delivering either directly or indirectly to a shoot 39 and thence to a trailer (not shown), the harvesterframe 2 is mounted on a pair of laterally-spaced wheels 16, 27 carried by cranks 14, 26, the stubble-ward wheel 27 being forward of the grassward wheel 16 so that the wheels are longitudinally offset but are interconnected for conjoint adjustment by means of a ram 5, the interconnecting linkage including a lever 20, 69 connected to each crank and a member 60 pivoted between the levers and connected to the ram. In Fig. 1, the rotor 35 delivers directly to the shoot 39, but in Fig. 3 an auger 40 first receives. the cut crop and delivers it to a fan 43 by which it is blown up a spout 44 into the shoot. The crank 26 is mounted on a shaft 21 extending across the rear of the frame and the lever 20 is secured to the grassward end of it. The shaft can be made telescopic, as in Fig. 6, the portion 50 being slidable within the portion 21 and lockable therein by nuts and bolts 51 so that the wheel 27 may have two alternative positions (full and dotted lines). The grassward wheel also has two positions caused by rotating the crank 14 through 180 degrees about its crank-axle, the lever 69 being detachably secured to the crank by bolts 67 to permit this. Initial settings of the wheels 16, 27 are adjustable by alternative holes 64, 76 for the pivotal connections to the levers 20, 69.

Title: Supply and distribution of ink in printing machines
IPC: B41F31/28
Filed: 1945-09-10
Abstract: 598,789. Printing-machines. CLARKE, F. J. Sept. 10, 1945, No. 23279. [Class 100 (ii)] Inking-apparatus of the kind in which the ink is sprayed on to a printing-surface or roller in a state of fine division in a stream of air or other gas is provided with a mask, screen, or stencil for limiting the inking action to the actual printing-surface. As applied to a bed- and-cylinder machine in which a forme 2 is reciprocated under an impression cylinder, a stencil which is made from the forme is attached to a frame 6 which is secured to the bed by a projector 9 and latch 10 as the forme moves past the spraying-device 12. The spray passes through the stencil on to the forme, and the frame 6 is detached from the bed by a projection 7 during the printing operation. As applied to a rotary machine an arcuate stencil is used which moves with the forme cylinder during the inking of the forme, and has a quick return motion so as to be clear of the forme during the printing operation. The ink employed is a quick drying ink, and a low boiling point diluent mineral oil may be added to inks having a mineral oil medium. French specifications 424,609 and 513,260 are referred to.

Title: Safety belt devices
IPC: B60R22/40
Filed: 1974-05-24
Abstract: 1474416 Inertial safety belt N G Y TORPHAMMAR and P G TORPHAMMAR 24 May 1974 [24 May 1973 30 July 1973] 23290/74 Heading A3V In a retractable safety belt the pawl 9 which locks the ratchet on the drum is actuated by one arm of a lever 23, the other arm of which (20) has a peg 19 which bears against the conical base of a pendulum 13. When the pendulum swings from its central position a spring 16 accelerates its movement and the conical surface depresses the peg 19 to pivot the lever 23 and cause the pawl to engage the ratchet. When the belt is next retracted, the ratchet pushes the pawl out, causing the lever 20 and its peg 19 to push the pendulum back to its central position. To inhibit the pawl from catching on the point of a tooth the pawl pivots about a slotted hole 25; a spring 26 and an arm 27 which slides up an inclined surface on a fixed arm 28 causing the ratchet to engage fully. In a modification (Fig. 9) the pawl has an arm 31 with an inclined camming surface which tends to return the lever (23) to its first position again as the pawl moves into engagement with the ratchet, thus simultaneously locking the ratchet and resetting the pendulum.

Filed: 1924-10-02
Abstract: 244,850. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Oct. 2, 1924. Electric braking. - A hoisting and lowering motor 5 is controlled by a braking switch 9 in conjunction with a resistance varying switch 7 and a timing relay 10, the arrangement being such that the sequence of resistance changes during graduated rheostatic braking varies from the sequence employed in acceleration owing to the action of a switch 6 which short circuits a part of the last resistance section. With the motor in the rheostatic braking loop, Fig. 2, the cumulative action of the relay coils 11, 12 keeps the actuating coil of the switch 6 de-energized until steady conditions are attained, after which the relay is opened automatically and the final portion of the resistance brought into use to give maximum lowering velocity. Specification 173,953 is referred to.
