Title: Improved attachments for typewriting machines
IPC: B41J17/00
Filed: 1948-03-25
Abstract: 657,108. Typewriters. EGRY. Ltd. March 25, 1948, No.8850. Convention date, March 29, 1947. [Class 100 (iv)] In a manifolding attachment for typing on a number of continuous paper webs 34, a paper guide frame 3 which participates in the movements of the typewriter carriage 2, has displaceable along it a slide 18 having paper web grippers 21, 22, which anchor the paper webs when at one end of the frame and release the paper webs at the other end ; the frame 3 carries also a slidable member 6, movable towards and away from the platen, and over which the paper webs pass to the platen, and chains or bands 13 secured at one end to the frame 3 and at the other to a carbon sheet carrier 14. The member 6 has rollers 7 on each side which engage and travel on tracks formed by the H-bars of the frame 3, and a lug 8 on each side, each having a bearing hole so that the member 6 may slide up and down on rods 9 fixed to the frame 3. A spring 10 surrounds each rod 9 maintaining the member 6 normally in a raised position as shown. Paper webs 34 are threaded through the grippers which comprise an angle rail 21 and a pivotal blade 22 coacting therewith by the action of a forked arm 25 having segment teeth 28 engaging corresponding segment teeth 29 on an arm 31 pivotally mounted on the slide 18. With the slide 18 in its uppermost position on the frame against a stop 20, the webs are led from the grippers over a roller 11 on the member 6 and are gripped by the platen 35. Advancement of the platen causes the member 6 to be lowered, and during this movement a pin 32 thereon engages the arm 31 causing arm 25 to open the gripper blade 22, thus allowing the slide 18 to fall to the bottom of the frame track. At the lower end a stop 33 engages the arm 31 to close the grippers again. The carbon sheets 17, advanced with the webs, will by now have been gripped by the platen and during continued feed by the platen during typing the member 6 is further lowered by the pull on the chains 13 extending from the carbon carrier 14 over the roller 11 to an anchorage on the frame 3. When typing is completed the webs and carbon sheets are wound back until the latter are released from the platen, whereupon the member 6 rises to its initial position. The webs are now fed forward by the platen and since the webs are gripped by the members 21, 22, the slide 18 is moved back to its original position while the carbon sheets remain stationary ; the device is then ready for typing the next set of sheets.

Title: Improvements relating to the combination of a spinning or twisting machine with a further thread-treatment machine
IPC: D01H9/04
Filed: 1931-03-24
Abstract: 375,803. Arrangement of spinning and like machines, and machines for subsequent treatment of threads. SCHNEIDER, H., 66, Zeltweg, Zurich, Switzerland. March 24, 1931, No. 9046. Convention date, April 17, 1930. [Classes 120 (ii), 120 (iii), and 142 (iv).] In order to obviate the individual removal of bobbins from spinning, twisting, or gill machines with interchangeable lifter plates and doffing- mechanism for subsequent treatment in machines such as twisting, reeling, finishing, or warping machines or quick-traverse winding-frames, the machines are so disposed that the full bobbins on the doffing-mechanism of the spinning or like machines are in the necessary position to serve as the creel bobbins of the treating machine. If it is inconvenient so to arrange the machines, the creel of the subsequent machine is modified to receive the lifter plates of the spinning or like machine. The output of the subsequent machine is such that the bobbins are emptied in the same or a shorter time than that in which they are filled in the spinning or like machine. The treating-machine is preferably mounted so as to be readily removable in order that it may be replaced by a different machine ; for example, in manufacturing twine for agricultural purposes a ball-winding machine and a quick-traverse winding-machine are removably mounted so that either may be used with a gill frame. As shown, a doffing-carriage e, such as described in Specification 228,846, [Class 120 (ii), Spinning, twisting, &c.], is mounted on rails o and the yarn from the doffed bobbins s<2> on the lifter rail g<1> is led over guide rollers z<1>, z<2>, z<3> to a winding- bobbin k. If the rail g is provided with bobbindrag arrangements, yarn-tensioning means may be dispensed with in the winding-machine.

Title: Method of and apparatus for filling cans and like containers with liquid, plastic orsemi-liquid materials
IPC: B65B3/12
Filed: 1941-07-23
Abstract: 550,783. Filling cans &c. with liquid, plastic &c. materials; rotary pumps. PROCTER & GAMBLE CO. July 23, 1941, No. 9346. Convention date, July 31, 1940. [Class 125 (ii),] [Also in Group XXVI] To obtain a uniform flow of material of uniform consistency in filling cans or other containers with shortening or other liquid, semiliquid or plastic material containing vesiculated gas, the material is supplied from a high pressure zone 2 to an elongated port 7 at which the pressure is abruptly released, the rate of flow through the port being maintained uniform by varying the opening of the port in response to changes in the high pressure. Two ports 7, 8 may be employed so that the material is caused to flow in two streams directed successively into each of a series of containers. The variation in the opening of the port or ports 7, 8 is determined by the variation in pressure at the opposite sides of a piston 9 ; if the pressure in the zone 2 momentarily increases, the piston is caused to cover more of the port or ports and increase the resistance to the flow of material. The pump 4 is driven at constant speed, e.g. by an electric motor 20. From the ports 7, 8 the material passes through passages 10, 11 to ports 14 in a rotating column 15 leading to the filling nozzles 16. The port 8 leading to the port 11 is smaller that the port 7 so that the material supplied last to the can is fed at a slower rate. To allow the filling operation to be discontinued while maintaining normal flow of the material through the pump and filling line, the cylinder (not shown) in which the piston 9 moves is slidable by means of a rod so as to cover completely the ports 7, 8 and to uncover a third port leading to an overflow tank. The port or ports may be replaced by a row or rows of apertures. The cans are fed to the filling table 21 by a feed belt 22 and star wheel 23, and during the filling operation are retained seriatim under a nozzle 16 by the arms of a star wheel 24 and retaining guide rail 25. After filling, the cans are removed by a star wheel 26 and conveyer 27.
