Title: Driving mechanisms for mechanical presses
Inventor: WISSMAN REUBEN E
IPC: F16D67/04
Filed: 1956-05-16
Abstract: 811,464. Mechanical presses. MINSTER MACHINE CO. May 16, 1956, No. 15284/56. Class 87(2). A mechanical press has an electrical motor driving successively a flywheel shaft, an intermediate shaft having a clutch and brake unit, and a crankshaft. The press has a base 10, sides 12, 14 and a crown 16 containing the driving mechanism for a vertically reciprocable upper platen 18 guided in adjustable gibs 20, Figs. 9, 10 (not shown), on the sides 12, 14. The driving mechanism comprises an adjustably mounted motor 22 with a pulley 24 and belts 26 driving a pulley 28 on a shaft 30 having a flywheel 39 and a pinion 34 meshing with a gearwheel 36 freely mounted on an intermediate shaft 38. The shaft 30 is mounted in eccentrically bored blocks 31, Fig. 11 (not shown), enabling either of two different sized gearwheels 36 to be used. The intermediate shaft 38 has at each end a pinion 44, meshing with a gearwheel 46 on each end of a crankshaft 48 having connecting rods 50 driving the platen 18, and a clutch-brake unit 40 pneumatically operated to transmit the motion of the gearwheel 36 to the shaft 38 and hence to the platen 18, but normally braked so that this motion is not transmitted. The pneumatic pressure operating the clutch may be controlled to allow the clutch to slip under a pre-determined load. The location of the clutch on the intermediate shaft instead of a higher speed shaft is said to ensure longer clutch life owing to the lesser static inertia to be overcome on operating the press. Two further embodiments are described in one of which, Fig. 13 (not shown), the crank shaft is driven at one end only by pinion 44 and gearwheel 46, and in the other, Fig. 14 (not shown), the crankshaft is driven by a centrally placed gearwheel 46 and pinion 44. Specification 769,359 is referred to.

Title: Sound producer comprising a vibratory system coupled with a resonator
IPC: G01S1/72
Filed: 1924-07-04
Abstract: 220,281. Signal Ges. Aug. 8, 1923, [Convention date]. Diaphragm vibrators.-In a sound-producer in which a mechanical oscillatory system, such as a diaphragm, is coupled with a resonator, each being tuned to the same natural frequency, the degree of coupling is not less than the percentage variation in the natural frequency of the resonator, due to change in temperature, i.e. not less than 4 per cent. This mimimum is necessary because of the variation of tuning of the resonator with temperature. Specifications 172,637, [Class 118(ii), Signals], and 202,938 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes a sound-producer in which the diaphragm 2 is coupled to the resonator 5 by a coupling chamber 4. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for accumulating metalic strip and the like
IPC: B21C49/00
Filed: 1966-04-13
Abstract: 1,067,640. Metal strip feeds; making strip. ARMCO STEEL CORPORATION. April 13, 1966 [March 3, 1966], No. 16162/66. Addition to 1,060,058. Headings B3A and B3W. [Also in Division B6] A web accumulating device of the type described in parent Specification, has the rotatable table 12 provided with a plurality of retractable coil restraining abutments or fingers 16. These abutments are pivotally mounted below the surface of the table 12 or the plane formed by the upper surfaces of radial support members (12c), Fig. 1 (not shown). Until such time as the web being advanced to a machine has substantially exhausted the innermost coils 28, the abutments 16 are maintained in an upwardly extending or operative position to restrain the outermost set of convolutions 27 as they are wound on to the coil. Retraction of the abutments 16 to allow the outermost set of convolutions 27 to collapse on to the innermost set 28 is controlled by web edge sensing elements 4 which detect the withdrawal of the last of the convolutions of the innermost set 27. These sensing elements 4 are connected to a solenoid operated valve means 7 which when operated release the air pressure to the cylinder 6 of the retracting mechanism. The table 12 is rotated by the friction between the web edges and the table as the web is withdrawn. This friction may be maintained with a hold down roller 5. Controls.-As in the parent Specification, the tension sensing roller 23 drops if there is a break in the incoming web thereby operating the switch 25 to halt the rotation of the table 12 with a brake 3. The switch further operates the valve 7 so that the abutments 16 are retracted to allow the outermost set of convolutions 28 to collapse on to the innermost set 27. The tension sensing device 30 initiates the rotation of the table 12 when the web tension increases, as in the parent Specification, but the rotation may be initiated with a " kicking " means 15 instead of a variable speed motor, withdrawal of the web causing the continued rotation of the table 12. Alternatively, the rotation may be initiated by a sensing device 36 with a spring biased arm 37 which senses the collapse of the outermost convolution of the coil 27. The abutments 16 are moved to their projecting positions as the table begins to rotate.
