Title: Improvements relating to cooling beds for metal bars
IPC: B21B43/00
Filed: 1926-04-01
Abstract: 273,789. Noell, A. April 1, 1926. Rolling.-Rolled bars which have been cut are discharged into a receiving channel or channels whence they are passed on to a cooling-bed in groups with spaces between each group and thus travel to the end of the bed from which thev are lifted off at the end to make room for succeeding groups, the whole operation of grouping, spacing, and traversing being performed automatically, either mechanically or electrically. Fig. 1 is a sectional elevation of the cooling-bed &c. Fig. 6 is a cross-sectional elevation of the control mechanism &c. in which the rod d, which moves the bars along, has a constant vertical stroke and an adjustable horizontal stroke. Fig. 7 is a diagrammatic arrangement of the automatic electrical control. A bar arriving in the receiving channel closes a switch 42 which starting a motor 25, causes the discharging flaps c to lift the bar on to an incline h. A cam on the discharging mechanism starts up the main motor 21 driving the main shaft 19 which is provided with a series of cams as follows : Cam 18 to operate linkwork 16 to give vertical reciprocation to the rod d ; cam u with lever 9 and engaged by a clutch 7 for making the horizontal control stroke; cam 10 with mechanism engaged by clutch 7 for producing the spacing stroke between the sets of bars ; cam 23 operating a. cut-out to stop the motor. The main shaft 19 is also provided with gears y operating timing pin-wheels and interchangeable chain i which determines the variable number of bars collected in a group to be passed over the cooling-bed. After the spacing stroke has been made the electromagnet 6 is out out by opening switch 5 and a second collection of bars begins while at the right-hand end the discharging carriages f begin to lift the end group of bars off the bed, such operation being started by the switch 34 starting the motor 31. This end group may be held suspended while the next group is passed into position, the end group being finallv moved by a. motor 35 which is cut out after discharge and the discharger f starts lowering again. The initial bar-receiver may consist of several channels formed by partitions provided with pockets at their upper edges.

Title: Improvements in or relating to electrical shaving machines for dry-shaving
IPC: B26B21/38
Filed: 1933-03-24
Abstract: 402,644. Shaving-machines. BRUNNER, W., 6, Obere Hardegg, Olten, Switzerland. March 24, 1933, No. 8956. [Class 131.] An electric shaving-machine for dry shaving, comprises two serrated cutting-blades one of which is stationary and the other reciprocable. The stationary cutting blade is an unhardened, unground flexible lamella 31 of a maximum thickness of .07 millimetres, is serrated on both longitudinal edges, the serration tips being turned away from the skin at 34, and is pressed, together with an overlying lamella 32 which is cut back to expose the serrations of the lamella 31, against the reciprocating rigid cutter 20. The pressure is applied by a curved plate 33 secured by bolts 35 having dome shaped heads which are cut away on opposite sides to fit within rectangular openings in the plate 33 whereby rotation of the bolts is prevented. The plate 33 and the lamellµ are pressed down upon a bar 30 which bridges the reciprocating cutter and is supported on shouldered screwed sleeves 29 which are rotatably adjusted to vary the effective height of the bar 30 and consequently the tension between the cutting-blades. The flexing of the lamella 31, 32 is such that the angle alpha, Fig. 8, made with the cutter 20, exceeds three degrees. The cutter 20 extends substantially the whole width of the lamella 31, the tips of its serrations projecting just beyond the bottoms of the serrations of the stationary cutter. The cutter 20 is reciprocated by a slide 12 to which it is connected by pins 21 on the slide projecting into holes in the cutter. Springs 22 prevent play between the pins 21 and the holes in the cutter due to wear &c. The slide 12 is reciprocated by an eccentric 18 on the shaft 16 pivoted in a cylindrical slider 14 housed in a guide way in the slide 12. The slide 12 is counterbalanced to prevent vibration by an oppositely reciprocating and similarly driven slide 13 suitably weighted at 47. The cutters are protected in advance of the shaving position by rake-shaped guards 38. The cutters and the drive therefor are mounted upon a casing 4 containing rotary air-impellers 44 which suck in air through apertures 5a and deliver it through passages 40 on to the cutters at the shaving position. The cut hairs are thus blown out through the lines of the guards 38 and the cutters are kept cool. Hairs are prevented from reaching the driving mechanism by the plate 25, Fig. 8, which projects into a recess in the driving-mechanism casing. The machine is driven from an electric motor through a flexible shaft. The surface to be shaved is illuminated by a small incandescent lamp in parallel with the motor circuit.

Filed: 1945-04-18
Abstract: 590,308. Liquid meters ; valves. MILES, F. D., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 18, 1945, No. 9680. [Classes 69 (i) and 135] A liquid-measuring apparatus comprises valves 22 and 28 connecting a receiving tank 9 and a main tank 1 in which a bell siphon structure 3 reciprocates about a stand pipe 4. The lower portion of the siphon structure 3 is of greater diameter than the upper portion and slides freely in a guiding cup 7, whilst a float trough 2 is built around the upper portion. Liquid from the main tank is able to pass through a port 8 to the interior of the siphon structure 3 when the latter is in the lower position. The action of the apparatus is as follows : at the end of the discharge of the main tank the siphon breaks, the liquid falling back causing an independent float 10 to open the inlet valve 22 by means of a push-rod 12. Liquid enters the main tank from the receiving tank 9, further raising the float 10 and also raising the structure 3. A stop 19 causes the float 10 to disengage from the inlet valve 22 which closes, the liquid entering by the valve 28, whilst a stop 25 limits the upward movement of the structure 3. The liquid on reaching a certain level in the tank 1 flows into the trough 2, sinking the structure 3 and causing the siphon to empty the tank 1 whilst closing the inlet valves 22, 28. As the level in the tank I falls below that of the trough 2, siphons (not shown) empty the trough 2 into the main tank 1. In a modification, the independent float is concentric with the structure 3 and opens both valves 22 and 28 simultaneously. A counter 30 records the number of operations of the apparatus.
