IPC: B43K23/00
Filed: 1956-07-27
Abstract: 823,409. Pouches. GIBBONS, T. G. July 26, 1957 [July 27, 1956], No. 23336/56. Class 133. [Also in Groups VII and XV] A holder for pencils, pens, rulers or other small articles comprises a generally flat, open-topped flexible pouch provided at its upper edge only with at least two spaced spring clips which may be hooked over the edge of a jacket pocket to support the pouch. The pouch has front and rear walls, 11, 12, e.g. of leather, leathercloth or a plastic material, which are sewn together on three sides. The pouch is divided into four compartments 20, 21, 22, 23 by rows of vertical stitching 17, 18, 19, of which 20, 21 may hold a fountain pen and ruler respectively and 22, 23 may each hold a pencil. Access to the compartments 22, 23 is facilitated by a V-shaped notch cut in the upper-edge of the front wall 11. Two clips 26, 27 each consisting of a strip of spring steel doubled over on itself, are attached to the pouch and secure it either inside or outside a pocket. One leg of each clip extends into each of the outer compartments 20, 21 and is there riveted to the rear wall 12 of the pouch.

Title: Improvements in or relating to the trigger mechanism of machine guns and automatic small arms
IPC: F41A19/33
Filed: 1924-10-03
Abstract: 245,489. Vickers, Ltd., and Tucker, L. Oct. 3, 1924. Machine guns.-Trigger mechanism adjustable for single-shot and continuous firing has the pivoted sear mounted to have a limited longitudinal movement under the influence of a spring in such a manner that, when the mechanism is adjusted for single-shot firing, the sear, as soon as the striker is released, is moved longitudinally by the spring so as to free it from the trigger irrespective of any further movement of the trigger, and when the mechanism is adjusted for continuous firing, the longitudinal movement of the sear is prevented so that the trigger remains in engagement. As shown, the sear C is mounted on a pivoted block C' so as to have a small sliding movement, and when the gun is cocked is moved to its forward position by the pressure of the firing spring. The sear spring C<3> is inclined so that it produces both the rocking and longitudinal movements of the sear. At the rear, the sear has a spring pawl C<2> engaged by the trigger. The adjusting device is a rotatable stop A which, when set to the single-shot position, shown in Fig. 1, is out of the path of the sear, sq that as soon as the striker B is released the sear is moved rearwards by its spring C<3> and the pawl C<2> is disengaged from the top step of the trigger. In the continuous-fire setting, Fig. 4, the stop A prevents the rearward movement of the sear by engaging a projection C<4>, and also limits the rocking movement of the sear so that it cannot become disengaged from the trigger. In the safety position,. Fig. 5, the stop A locks the trigger but leaves the sear free. The adjustable stop A is utilized as a fastener to secure the side plate E', Fig. 6, a bayonet-joint permitting the removal of the plate when the stop A is turned to an extreme position.

Abstract: 723,888. Making paper tubes. PELLETER, L. A. Oct. 9, 1951. [Dec. 8, 1950] No. 23529/51. Class 99 (2). In the manufacture of paper bags a strip 1, or a number of superimposed strips, of paper unwound from a roll is successively and continuously formed by shaping-elements into a tube having inwardly folded lateral panels, Fig. 7, the panels afterwards being outwardly folded, Fig. 8, relatively to creases 12, 13 and 16, 17 which define the width of the bag when opened for filling. The strip 1 may pass between a rubber-covered roller 2 and a cylinder 3 carrying a plate 4 which marks a transverse fold of the bottom of the bag, and then to a glueing device 6 which deposits a stripe of glue 10 on or near one edge of the strip. The strip is then directed over a wheel 11 which marks two longitudinal creases 12, 13 in the paper, and then onto two converging metal sheets 14, 15 mounted on a support 18 and co-operating in a known manner with lateral convergent blades to mark creases 16, 16<SP>1</SP>, 17 and 17<SP>1</SP>, and to form, together with the creases 12, 13 lateral panels. A cylinder 19 and rollers 20 crush the creases 12, 13, 16 and 17, Fig. 7, and a plate 21 engages the inward lateral panels from the inside of the tube and causes the direction of the panels to be reversed, Fig. 8. Finally, after passing between a cylinder 22 and rollers 23, 24 which crush the creases 16<SP>1</SP>, 17<SP>1</SP>, the tube is cut into lengths by a knife 25 carried on a cylinder 26 and a co-operating stationary knife 27, each length being directed to another part of the machine to complete the formation of a bag. When the tube comprises more than one layer both the lining and outer envelope may be marked with printed inscriptions before passing to the rollers 2, 3. In a modified form of the apparatus, Fig. 2 (not shown), the upper sheet 14 has recesses in which the rollers 20 are located.

Apparatus for supplying feed to animals comprises a feed hopper 12 above a tray a trough 10 and flow control means governing the flow of feed from the hopper 12 to the tray 10 including actuating means displaceable by the animals for moving a flow control member. The lower part of the hopper 12 has a truncated conical section tapering to lip 17 which defines an opening. A rotary flow control disc 18 slightly larger than the opening is arranged below it and below that is mounted a conical spreader 19 with fins or blades 20. As the animal eats, its snout engages the fins 20 causing the spreader 19 and hence shaft 25 to rotate. This rotates disc 18 and spills the feed piled on the disc 18 on to the spreader 19 and into the tray 10. Scraper arms 40 are mounted on an eccenrtic boss by means of yoke 37. The flow control disc 18 may be adjusted vertically by means of rod 31 and lever 33. A cylindrical casing 21 encloses the lower part of hopper 12 and the disc 18.

Abstract: 235,746. Good, W. B. Aug. 12, 1924. Thermal current meters; temperature errors, compensating for.-The main current terminals a, b of a thermal ammeter are connected by a heating strip or wire c to which is thermally connected the hot junction d of the main thermoelectric couple d<1>, d<2>, the connection preferably being made through a short length of wire c<1>, serving only as a heat conductor. ' The cold ends d<3>, d<4> of this couple are each connected to the galvanometer e by means of subsidiary or compensating thermo-electric couples f<1>, f<2> and g<1>, g<2>. The hot junction f<3> of the couple f<1>, f<2> is connected to a compensating-plate h which is thermally connected to the terminal b but electrically insulated therefrom, as by a sheet of mica i. Similarly, the hot junction g<3> of the couple g<1>, g<2> is connected to a plate j which is thermally connected to but electrically insulated from the terminal a. The wire d<1> may be iron and the wire d<2> eureka, the wires g<1>, f<2> being of copper and the wires f<1>, g<2> of constantan. The ptates h, j may be of copper or other metal. The same materials may be used in the compensating couples as in the main couple, provided they are arranged to produce a reverse current from that due to the main couple.. The current generated by the compensating couples is equal to that generated by the main couple after the main circuit current is broken, thus bringing the indicating needle rapidly to zero. The indicatoris calibrated to allow for the reverse current generated in the compensating couples.

Convention date, Aug. 24, 1931. [Class 38 (i).] A main fuse wire under tension is arranged in series with a pilot wire having a lower fusion point and not under tension, means being provided to ensure rupture of the main tensioned wire when the pilot wire fuses. The main fuse 16 is embedded in incombustible filling material 11 enclosed in a long insulating shell 10 having metallic end caps 12, 13 which are secured in position, together with covers 20, 21 by screws. The fuse 16 is tensioned by a spiral spring 25 anchored to a metal shaft 24 carried by the cap 13 which is electrically connected to the cover 21. The other end of the wire 16 passes through an insulating plate 22 and then through a centre hole in the end of the cap 12 without touching it, and is secured to an insulating cross bar 17. The pilot wire 19, located in a small explosion chamber, connects the end of the main wire 16 to the metal cap 12 and cover 20. An excess current fuses the pilot wire 19, and gases generated in the explosion chamber facilitate the setting up of an arc between the edges of the central hole in the end cap 12 and the wire 16, thus melting the wire at the point where the arc strikes it. The incombustible material rapidly cools and quenches the arc as the ruptured wire is withdrawn through it by the spring 25.
