Title: A machine for use in laminating dough
IPC: A21C3/02
Filed: 1952-03-12
Abstract: 707,023. Dough-laminating machines. GRIFFIN & SONS, Ltd. March 12, 1952 [March 12. 1951], No. 6482/52. Class 87 (2) A conveyer belt or web 36, Fig. 1, passes round free running rollers 37, 38, 39, 40, and round roller 41 which is constrained to turn freely only in a clockwise direction by a pawl 45 engaging in ratchet wheel 44. The upper portion of the belt rests upon the floor of a tray 34 which is reciprocated lengthwise of the machine by the lever arms 30 which are rocked by the crankpins 28 driven by an electric motor 4. The rollers 37 and 38 are mounted on the tray, the others, 39, 40, 41 are mounted in the frame 1 of the machine. A continuous ribbon 23 of dough is fed from the hopper 22 to the belt 36 by the adjustable pressure drums 21, driven in opposite directions by the electric motor 4 via worm gearing 18, 19. The speed of the rollers and the tray may be varied independently by gears 6, 8 and 25. When the tray 34 is moved forward by the arms 30, the friction between the top portion of the belt 36 and the floor of the tray 34 constrains that portion of the belt to move forward with the tray, with consequent rotation of roller 41 in the direction of the arrow in Fig. 6. As the tray moves forward, a knife blade 47 is depressed to cut the ribbon (Fig. 6), by the pawls 50 on the cam bar 46. After reaching its extreme forward position, the tray returns, roller 41 remaining stationary, the belt being taken up between rollers 38, 39 and the severed sheet of dough being deposited on support 3. The cycle is repeated to build up the desired number of superposed laminae on a stationary support or of staggered laminae on a conveyer moving transversely at slow speed.

Title: Automatic locomotive water scoop control
IPC: B61C17/02
Filed: 1937-03-10
Abstract: 490,772. Water pick-up apparatus for locomotives. CARTER, J. A. March 10, 1937, No. 7053. [Class 79 (i)] The water pick-up scoop of a locomotive is automatically removed from the trough when the water reaches a predetermined level in the locomotive tank, thereby preventing overflowing of the tank. As described, the scoop is raised by a float L in the tank under the control of a pilot float A, but steam or other power may be used in place of float L. Referring to Fig. 1 (Prov.), the scoop W is connected with a three-armed lever SST loose on a shaft UW, the scoop being normally held in its raised position by the arm T of the lever resting on an arm V fast with shaft UW which is connected to a hand gear Y. The float L in the tank is carried by a rocking beam O connected by a rod P with a slotted link R engaged by an arm S of the three-armed lever. As the water level in the tank falls, float L falls also, rod P being ultimately locked to secure the float by a spring catch I. To lower the scoop hand gear Y is operated, arm V rotating clockwise and the three-armed lever following under the weight of the scoop. When the tank is nearly full, the pilot float A releases catch I of the main float L which rises rapidly, turning the three-armed lever back to raise the scoop. The hand gear Y is then operated in the reverse direction so that arm V engages arm T to support the scoop. In the modified construction shown in Fig. 1 (Comp.), the supporting mechanism for the main float L and pilot float A is mounted within a housing AE on top of the water tank WX. The locking catch for the float L is mounted in its supporting beam O, and it is disengaged from a slot in the bearing bracket AE<3> of the beam by means of a push rod operated by the pilot float A.

Abstract: 413,246. Fountain pens. JOWITT, J. S., 3, Clifton Square, Lytham, Lancashire. March 6, 1934, No. 7167. [Class 146 (iii).] In a piston self-filling fountain pen, the portion of the barrel in which the piston slides is provided with two ports connected by a channel and so arranged that the compression produced by the first part of the movement of the piston is released during the latter part. The piston 7, which may be formed of aluminium and may be a plain disc, a cylinder with or without grooves, or grooved with usual packing, is slidable in a cylinder 5 closely fitting in the barrel of the pen and provided with apertures 14, 15 connected by a groove 16 in the outer wall. The end of the cylinder is closed by a disc through which the piston rod 9 passes and which is formed with an opening 11. A rod 8 prevents the piston from being pushed too far in. In use, the nib is immersed in ink and the piston withdrawn to induce a supply of ink. The piston is then rapidly returned, so that the compression caused by the movement of the piston until the port 14 is uncovered cannot act to eject ink from the feed-bar before the pressure is released. The action is repeated until the reservoir is full.
