Abstract: 649,002. File-cutting machines. BOOTH, C. H., and HARDWICK, H. B. April 13, 1948, Nos. 10244/48 and 1539/49. [Class 83 (iv)] [Also in Group XXIII] A machine for producing teeth on files, saws, &c. comprises a chisel 27 which is reciprocated to strike a tool-blank 22, one or more bearing- members to support the blank during striking, a carrier 32 which is rotated about the blank and which carries hammer members 36 repeatedly to drive the chisel and the bearing member or  members simultaneously into engagement with the blank, and means for feeding the blank between strikes to form a succession of gullets and sharp-edged ridges. In the machine described, the bearing-member is a second chisel 27. The chisels are adjustable in holders 25 by wedge means, the holders being mounted by resilient rubber sleeves 31 in sleeves 29 resting in sockets 15. The chisels are reciprocated by the rollers 36 in the fly-wheel 32 which is rotated by pulley means 34. The blank 22 is fed continuously by means embodying a cushioning device. The rollers 36 are inclined and are moved axially by means 46 to adjust the stroke. The natural frequency of vibration of the resilient mountings is substantially equal to the normal frequency of reciprocation of the chisels. Three chisels or, as stated in the first Provisional Specification, four chisels, may be provided.

Title: Improved means for pressing material into receptacles for baling purposes
IPC: B65B1/24
Filed: 1935-04-04
Abstract: 454,853. Filling-machines. LEGG, 0., 21, Goswell Terrace, Goswell Road, London. April 4, 1935, No. 10475. [Class 94 (i)] In a machine for pressing material into receptacles two or more ramming heads are provided for continuously operating in separate receptacles, the heads being independently and selectively operated by a common driving means. As shown, two rods 1, 2 have heads 3, 4, provided with suitable openings to allow the filling material to pass through while the heads are being raised. The receptacles 5 and 6 are filled from cyclones 28, 29 respectively from a single input 26. When a ramming head is in use its driving cams 14, which raise its rod intermittently and then allow it to drop, are rotated through clutch 18, 19 and bevel gearing 15, 16 from a common drive 21. Spring 13 absorbs shock as the ramming head falls. The clutches may be controlled by hand or may, as shown, be controlled by the cyclone input valve to allow only that head to be in use which is associated with the receptacle being filled. The invention is stated to be particularly adapted for filling sacks with paper recovered from spoilt cigarettes. Reference has been directed by the Comptroller to Specification 389,964.

[Classes 92 (ii) and 119.] Relates to breech actions for machine guns or automatic small arms of the kind in which the breech block 7 carries a transverse locking-bolt 15 operated by the movements of an actuating-slide or striker-post 14 relatively to the breech block, the rearward movement of the slide after releasing the locking-bolt serving to open the breech and the forward movement of the slide after closing the breech serving to lock it. The invention comprises in combination the following features, (1) inclines 19<a>, 19<b> on the slide which engage inclines 18<a>, 18<b> on lateral projections on the locking bolt to move the bolt into and out of engagement with a stop face 17 on the breech frame ; (2) an extension x of the slide which moves idly over the locking-bolt prior to unlocking and after locking; and (3) a locking- bolt which by pressure on the surface 2 of the breech casing during forward movement of the slide transmits through the inclines 19<a>, 18<a> the closing force to the breech block. The stop face 17 is slightly inclined to permit of ready release of the locking bolt and to convey a forward closing pressure to the breech block at the instant of locking.

In one form for screw-threaded caps, the resistance support comprises an indiarubber ring 5, Fig. 1, which is stretched around the outwardly bent upper edge 4 of the metal shell 1 of the cap, the resistance 6, of disc or tablet shape, being placed upon the central contact 2 of the cap and prevented from lateral movement by the upwardly extending edge of the ring 5. Alternatively the resistance holder may comprise a ring of porcelain, steatite, artificial resin, or other insulating material, which is secured by cement upon the end face of the lamp cap and embraces the resistance member consisting of insulating material carrying a flat resistance winding with a contact disc on each side of it ; alternatively a flat spiral resistance winding may be embedded within insulating material. In a modification for bayonet-joint lamp caps the contact faces 14, 15, Fig. 3, of the cap are separated from the metal sleeve 13 by a conical insulating member 16 to which is cemented a ring 5 provided with a transverse wall 17 forming two receptacles for segmental resistance bodies 18, 19 which may consist of compressed tablets of wire resistance. For use with lamps in an inverted position the resistance holder may be provided within the socket and surrounding the bottom contact, the resistance body being mounted on this contact, after which the lamp is inserted. Instead of the resistance holder surrounding the resistance, studs may be cemented to the upper surface of the lamp cap to engage corresponding apertures in a resistance body.

Title: Improvements in Fourdrinier Paper Making Machines.
Inventor: MILNE SAMUEL
IPC: D21F1/18
Filed: 1918-07-04
Abstract: 128,425. Milne, S. July 4, 1918. Fourdrinier paper-machines; shaking-apparatus for wire-cloths.-In order that the speed of vibration of the wire cloth in a Fourdrinier machine may be correspondingly increased when the machine is run at a greater speed or made of a larger size than usual, only those parts are vibrated which are essential for the felting of the paper, the essential feature of the invention being that the wire and breast roll, or the wire, breast roll, and guide-roll, are vibrated independently of the tube rolls and their supporting frames, which may be incapable of vibrating, or, if vibrated, are vibrated by separate means. The axle of the breast-roll a may be arranged to slide in bearings b and coupled by flanges a<1> and a grooved and sliding block and connecting-rod e with a lever f of adjustable throw. Both the breast roll a and the guide-roll o may be connected to a common vibrating shaft t. The breast roll may be supported upon a flexible frame and carry the double frame, so that the deckles are also vibrated, a suitable gap being left between the breast roll frame and the frame carrying the tube rolls to facilitate the removal and replacement of the wire cloth. When the deckle frames are fixed, the upper length of the straps are prevented from moving laterally, the lower lengths being in contact with the wire cloth and moving with it. The suction boxes r are preferably arranged in an inclined position, the wire passing over one or more suction boxes before passing over the guide-roll o, and when the couch rolls q require at times to be adjusted, a wire roll w is placed immediately after the last vacuum box. The deckle straps are carried over the first vacuum box. The dandy roll y is placed between two vacuum boxes at a part of the wire which is not vibrated. The under wire rolls s are preferably carried from the sole plate k, the roll s<1> nearest the breast roll being adjustable horizontally and used as a stretcher roll, and the distance between this roll and the breast roll being such as to avoid stretching the wire by the vibratory movement.

Abstract: 813,809. Agricultural implements. WARNOCK & SON Ltd., J. July 12, 1957 [April 12, 1956], No.11087/56. Class 6(1). A tractor drawn machine for use in preparing seed beds comprises transverse angle members 15 mounted on a frame 13 provided with members 11 for attachment to the three point linkage 29, 33 of the tractor. The members 15 are arranged so that the lower faces of the members are forwardly and upwardly inclined. The members 15 and frame 13 may be formed separately from the members 11 so that the frame may be reversed and secured to the members 11. Adjustable tines may be fitted on the front of the frame to break up soil compacted by the tractor wheels. An adjustable fin may be mounted at the rear of the implement to reduce the tendency to drift on sloping ground. The ends of the members 15 may be joined by metal strips to reduce lateral spillage of soil. The implement may be weighted by placing a box of stones on the frame. The implement may be used as a transporter for a chain harrow which could be loaded on the frame.
