Title: Improvements relating to machines for cutting leaf tobacco
Inventor: WARD HARRY
IPC: A24B7/12
Filed: 1963-03-28
Abstract: 1,071,636. Cutting tobacco. AMF INTERNATIONAL Ltd. March 26, 1964 [March 28, 1963], No. 12375/63. Heading A4C. A rotary cutter, for cutting tobacco, comprises knives 49 each frictionally clamped to a rotary drum 2 between a base plate 42 secured to the drum 2 and the toe portion 26 of an outer plate 16, the latter having a heel portion 22 with a face 34 bearing on a tapered heel plate 8 fitted in a recess 6 in the drum 2 and the gripping pressure on the knife 49 being determined by the degree of flexure of the outer plate 16 when the latter is secured, such as by screws 36, to the drum 2. The gripping pressure is pretermined in dependence upon the degree of taper 48 provided on the heel plate 8 whereby on clamping the heel surface 34 hard against the heel plate 8 the outer plate 16, which bears on the knife 49 at the tip of its toe portion 26, is flexed to the desired extent.

Title: Improvements connected with opening means of or for sheet metal boxes
IPC: B67B7/00
Filed: 1919-05-17
Abstract: 145,223. Moon, R. B., and Adams, F. E. May 17, 1919. Embossing; seaming.-In order to weaken sheet-metal boxes in certain directions to facilitate opening by tearing, indentations or the like are formed in the metal sheet by tools reciprocating rapidly through a small distance. The sheet 10 to be indented is fed by rolls or a conveyer 12 over anvils 3 which are capable of rocking in the table 2 to adjust themselves to the tools 1 which are mounted in a slide 4. This slide makes 1000 to 3000 strokes of <1>/16 to <1>/18 of an inch per minute. The eccentric 6<x>, which moves the slide, is connected to it by a rod 27 having a knee-joint which is connected by a link 26 to a lever 25 having a pin 24 engaging a slot 23 in a bar 20 which is reciprocated in guides 21 by a crank-pin on a rod 22. Fingers 15 are arranged to be raised by the passing sheet 10 against the action of springs 18, and when both are raised the right end of the bar 20 falls and the pin 24 comes into line with the upper part of the slot 23, and the knee is straightened against the stop 4<x>, but when either of the fingers fall, the bar 20 is raised, the pin 24 comes into line with the lower part, and the knee is bent, thus raising the tools out of action. The tools may have a screw or micrometer for adjusting them, and the reduction in the sheet effected by them may be <6>/1000 of an inch. For circular parts they may be rotated on a circular bed or anvil.

[Class 97 (i)] Apparatus for examining the grain of a photographic image layer by measurement of the total quantity of directed incident light transmitted by the layer and the quantity of the transmitted light not scattered by the layer comprises a photometric comparison field and a substantially punctiform light source illuminating the comparison field by light travelling along two different paths serving respectively for measurement and for comparison, the light serving for measurement being projected by a lens and mirror on to a translucent plate in the neighbourhood of the comparison field, and the light serving for comparison passing to a second translucent plate in the neighbourhood of the comparison field, and a light controlling device arranged in the path of the light serving for measurement or in the path of the light serving for comparison or in both paths. As shown an image of a punctiform light source 1 is projected by a lens 2 and mirror 3 on to an opal glass plate 4. Light rays serving for comparison fall on the opal glass plate 5 after passage through the adjustable grey wedge 6. The Lummer-Brodhun cube 7 is observed through an eyepiece 8. A lever 12 is provided with a holder 11 for the photographic image layer, which can thus be moved either to the station 9 where the transmission of unscattered light is determined or to the station 10 where the total light transmission is determined. Diaphragms are provided at the stations 9 and 10. Specification 439,107 is referred to.

Abstract: 445,740. Time switches. McNAMARA, T. J., 16, Lucan Street, Gaulfield North, Melbourne, Australia. April 29, 1935, No. 12787. [Class 38 (v)] A time switch which is operated by the alarm winding stem 14 of an alarm clock 8 has a movable contact 23 in the form of a double roller, the supporting stem 21 of which is carred in an insulating casing 18 and pressed outwardly by a compression spring 19, the casing 18 forming part of a boss 16 mounted on the winding key 14 attached to the alarm spindle 11 and connected to the spindle by opposing coiled springs 17. The contact rollers 23 co-operate with fixed contacts consisting of plates 4, 5 and 12, Fig. 4, with interposed insulation and terminal connections 2, 3 and 13. At the limits of the contact travel recesses 9 are formed in the contacts, these recesses and the intervening insulating surface 24 being so formed that as the alarm stem commences to move, one of the springs 17 becomes tensioned until the roller 23 is forced out of a recess and snaps rapidly into the opposite recess. The roller is adapted to connect the plate 12 to the contact 4 or the contact 5 in its opposite positions. The fixed contact structure is secured to the rear of the clock by means of a bracket 7. By placing a change-over switch in the circuit the time switch may be arranged to switch on or switch off a controlled circuit at a predetermined time, Fig. 5 (not shown). In another circuit arrangement described, an alarm clock fitted with two independently-adjustable combined alarm mechanisms and switches of the type described, may be arranged to switch on and off a controlled circuit at different predetermined times.

Patent GB-131948-A (GB)
IPC: F41A23/28
Abstract: 131,948. Schneider et Cie. June 30,1917, [Convention date]. Field carriages.-Consists in obtaining a large angle of traverse about a vertical axis between the wheels by supporting the wheels on an anchored plate and arranging a flexible tie of constant length between the rear end of the trail and two fixed points on the plate equidistatnt from the said axis, the arrangement being such that the tail of the trail moves during traverse over the are of an ellipse having the said fixed points for foci, which arc is practically coincident with the arc of a circle struck from the axis of training. Fig. 2 shows in plan the wheels B of the carriage supported on plates D anchored to the ground by spikes E and connected by adjustable ties H, H' to a chain or cable I passing round a sprocket wheel or pulley G at the rear end of the trail C. The forward ends of the tie are pivoted to fixed points F on the plates D so that the whole carriage may be trained to either side about a vertical axis through the point 0, the tie deforming as shown in dot-and-dash lines but remaining of constant length. The wheels are guided during training by flanges d on the plates D. The training hand-spike L, Fig. 1, is pivoted at L<1> to the trail and provided with a pin J having a collar M which engages after the manner of a claw coupling with the sprocket G when the lever is lowered so as to lock the trail against movement. When the lever is raised, the sprocket is free to revolve, and the carriage can then be trained by the aid of the hand-spike. In a modification, the trail only is moved about a vertical pivot on the wheel axle, and the wheel plates are provided with channels to fix the wheels in position. Fine training movement is effected by a worm gear operating on the pinion G. In a further modification, Fig. 8, the ends of the tie are fixed to the trail and the deformable portion passes round rollers or sprockets F' at the fixed points F, and in some cases round a central roller or sprocket V. All-round training can be effected 'by providing a continuous flanged ring D for the wheels, and several pairs of fixed points such as F for attachment or guidance of the tie.
