Title: Means for cutting off measured lengths of material
Inventor: WALLIS LIONEL SELBY
IPC: B21D43/09
Filed: 1968-05-08
Abstract: 1,215,242. Metal strip feeds. L. S. WALLIS. 17 June, 1969 [8 May, 1968], No. 21670/68. Heading B3W. Strip material is fed to a press, guillotine &c. by a pair of feed rollers provided with two separate drive means. As shown, the roller 17 is driven by an electric motor or a belt driven from the flywheel 10 of the guillotine through a solenoid-operated clutch 20 and a one-way clutch 21. A preset counter 22 driven by the inner member of clutch 20 which is the outer member of the clutch 21 is re-set by engagement with a finger 23 on the movable guillotine blade 9 during a cutting stroke. The counter actuates a double-throw switch 24 which controls a solenoid operating the single revolution clutch 12 on the drive shaft 11 of the guillotine, and the solenoid operating the clutch 20. The roller can also be driven via a variable throw crank 13, a rack 14 and a one-way clutch 15 from the guillotine drive shaft 11. In operation the counter is set to permit the number of revolutions of the roller 17 which will achieve a feed distance nearest to that required and the variable throw crank 13 is adjusted to complete the feed stroke by advancing or retracting the strip the required amount. The switch 24 is set in position A to energize the solenoid controlling the clutch 20 and the roller 17 is rotated the pre-set number of times. The counter 22 then throws switch 24 over to position B to stop the roller by disengaging the clutch 20 and engage the clutch 12. The drive shaft 11 then makes one revolution which feeds the strip the amount for which the crank 13 has been adjusted and moves the blade 9 through a cutting stroke which re-sets the counter 22. A limit switch 25 operated by a cam 26 on the shaft 11 is included in the circuit of the solenoid controlling the clutch 20 so that a fresh cycle cannot start unless the blade 9 has returned to its up position. In another embodiment, Fig. 2 (not shown), the variable throw crank (13) is mounted on a counter shaft (27) driven through a solenoid-operated clutch (28) by a separate electric motor or drivn by a belt and pulleys (not shown) from the main shaft. A cam (29) on the countershaft operates a normally open switch (30) and normally closed switch (31) controlling respectively the clutch (28) between the motor and the feed roller (17) and the clutch (12), the circuit including a self-holding relay (32) which is energized by switch (30). After the pre-set number of revolutions of roller 17, throwing over of switch (24) to position B disengages the clutch (20) and actuates the clutch (28) rotation of the shaft (27) causing the cam (29) to close the switch (30). This energizes the relay (32) which disengages clutch (28) so that shaft 27 makes only one revolution during which the roller feeds the strip the amount for which the crank has been adjusted. Instead of the counter 22 one comprising a measuring wheel driven by the material being fed could be used.

Abstract: 455,391. Lubricating internal combustionengines. BRUNETTI,T., 110,Viadei Serragli, Florence, Italy. July 31, 1935, No. 21745. Convention date, Sept. 27, 1934. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 25, 1936.] [Class 12 (iii)] [See also Group XXVII] In a fuel-feed and lubricating system for internal-combustion engines having the fuel feed supply and the lubricating circuit interconnected, the system is fed by means of a pump operated by the engine with a mixture of fuel and lubricating oil, and a fuel feed reservoir is provided in the system at a level above the fuel injection devices of the engine so as to ensure a steady supply of fuel under gravity to the injection devices when the pump is not operating or while pressure is being built up in the system. The pump 4 forces liquid through a filter 6 to a channel 7 leading to lubricating passages, and also to a reservoir 9 forming an air chamber and supplying fuel by gravity to the fuel injection devices 11. The liquid acting as lubricant drains into the sump whence it is withdrawn by the pump 4 and re-circulated. The system contains a sufficient quantity of liquid to maintain the engine in operation for a definite period. In a modification a feed tank is provided separate from the fuel feed and lubricating system which, through a float valve, replenishes the liquid in the system as required to make up for the liquid which is consumed as fuel. In a further modification, a feed tank is connected by piping in the lubricating circuit to effect a gravity feed to the circulating pump, which causes the liquid to pass under pressure into the feed and lubricating channels of the fuel feed supply and lubricating circuit ; the liquid that has passed through the lubricating circuit drains into the sump whence it is pumped back to the feed tank. Lubricating oil is mixed with the fuel in a proportion not exceeding 1 per cent. Specification 394,856 is referred to. The Specification as open to inspection under Sect. 91 describes a modification in which the liquid collecting in the sump passes by gravity to a feed tank positioned at a lower level, whence it is withdrawn by the circulating pump. This subject-matter does not appear in the Specification as accepted.
