Filed: 1960-08-16
Abstract: 897,377. Sewing machines. EXACTA OFFICINA MECCANICA SPECIALIZZATA. Aug. 16, 1960 [Aug. 28, 1959], No. 28306/60. Class 112. A thread cutter in a linking machine comprises a stationary cutting blade, a pivoted arm, and means for swinging the latter whereby the free end of the arm engages the threads and moves it into contact with the cutting blade. Operation of the arm is accompanied by simultaneous release of the thread tension. A cutting blade 1 is mounted on a fixed support 2. An arm 3 is formed at its free end with a slot 3<SP>1</SP> and is fixed to a member 4 rotatable between ball bearings 12, 13. Member 4 is in screw-threaded engagement with a spindle 5 fixed at its upper end to a tube 6 slidable in a fixed tube 8. A spring 9 biases the tubes apart, and their relative displacement is limited by a screw 10 on tube 6 disposed in a slot 11 in tube 8. Depression of tube 6 causes arm 3 to swing, and the thread 24, engaged between the needle 25 and a print 26 of the rotary dial 25, is thereby drawn through the eye of the needle and moved into contact with the blade 1, the cutting edge of which passes through the slot 3<SP>11</SP> The thread on its way to the needle passes between a pair of tensioning discs 17, 18 and also passes over a check spring 27. Discs 17, 18 are urged together by a sleeve 19 acted upon by a compression spring 20. A slidable rod 22, coaxial with discs 17, 18 and sleeve 19, carries a cross pin 23. A lever 15 has one arm engaged with the lower end 14 of spindle 5 and the other arm engaged with rod 22. When spindle 5 is depressed, rod 22 thereby rises and pin 23 separates sleeve 19 from the discs 17, 18.

Title: Improvements in or relating to machines suitable for making bricks, blocks and the like
IPC: B28B13/02
Filed: 1933-10-16
Abstract: 426,806. Moulding sand-faced bricks &c. EDWARDS, J. W., Romney, New Dover Road, Canterbury. Oct. 16, 1933, No. 28572. [Class 87 (ii)] A machine for making sand-faced bricks, blocks, and the like comprises a pug-mill 1 connected by laterally-aligned openings 9 with a press-chamber 10 and a main drive shaft 14 rotated by the pug-mill shaft 4. Clay is forced by a plunger 11, reciprocated from the shaft 14, from the chamber 10 through a die-plate 12 and into one or more moulds in a box 22 carried on a table 19 adapted to be raised and lowered by a cam on the shaft 14. The table is raised for filling the moulds and the lowering is effected in two stages whereby, after moulding, the box is moved slightly away from the die-plate and one or more cutting wires 33, 33<a> are reciprocated, through a cam on the shaft 14, across between the die-plate and the mould to sever the clay, whereafter the box is moved farther away and finally delivered endways for removal of the bricks. The openings in the dieplate are less than the cross-section of the mould so that on extrusion the clay does not displace sand previously placed on the inner surface of the mould. The sides of the openings may be of convex shape. The mould boxes 22 are successively moved under the die-plate and endways thereof by a pusher 23 moved forward by a wire-rope 25 connected to a crank on the shaft 14 and retracted by a weight 27. In use, a filled box is moved endways for delivery by the succeeding box being pushed under the die and the pusher is then retracted to allow a further empty box to be placed in front of it. The table 19 is slotted and is carried adjustably on rods 20, 20<a> adapted to be reciprocated by cams on the shaft 14. Rubber bumpers 49 may be provided on the table so that the bricks may be loosened for removal by tapping the boxes. The cutting wires 33, 33<a> are mounted with tension means 42 in a frame 32 which is connected at its rear end and intermediately of its ends by ropes 38, 34 respectively to connections 36<b>, 36<a> on vertical rods 36 reciprocated by a cam on the shaft 14. The frame is normally held in its inoperative position by a tripper rod 40 which is displaced by a cam on the shaft 14 to allow the rods 36 to pull the rope 34 to effect the cutting movement. Further movement of the rods 20 thereafter moves the table 19 still lower and the pusher is operated to deliver the filled box for removal of the bricks. The plunger 11 is carried by rods 43 carrying lateral arms 44 having anti-friction rollers 45 engaging an eccentric 46 on the shaft 14.

A lock, especially for doors of cold rooms, comprises a sliding latch bolt 3, urged by a spring 4 to engage in a notch 9a formed in a keeper 9, the bolt being withdrawable from the notch by a barrel lock 5, the keeper.being rotatable in a bore 11, formed in the door frame M, by means of a handle 17 located inside the cold room, rotation of the keeper from the locked position shown causing the notch to be rotated away from the bolt so that the latter bears on an unnotched part of the keeper, whereupon the door may be pushed open from inside the cold room. On rotating the keeper, movement of the bolt 3 is permitted by a lost motion connection (recess 8 and lug 7) between the bolt and the barrel of lock 5. The handle is secured non- rotatively to a square-sectioned rod 12, having threaded edges which engage in a tapped bore 15a, so that movement of the handle to the door-unfastening position results in an axial shift of rod 12 towards the bolt. Rod 12 is secured to the keeper through the intermediary of a sheath 13, e.g. of polyethylene, to reduce heat losses through the door. The lock casing 1 is secured to a plate 2, Fig. 2 (not shown), which is in turn screwed to the door P, no screw being accessible when the door is closed.

Patent GB-210142-A (GB)
Title: Improvements in and relating to thermionic valve transmitters for wireless telegraphy
IPC: H03H2/00
Filed: 1922-10-24
Abstract: 210,142. Preston, L. G., Shearing, G., and Matthews, C. Oct. 24, 1922. Thermionic generators-Valve transmitters are arranged to be convertible at will from direct aerial coupling to indirect coupling, the oscillations in the second condition being generated in a closed oscillatory circuit which is coupled to the aerial by resistance coupling or otherwise. The change over is effected by hand switches K, L controlling contacts a - - h. When contacts e - - h are closed, the valve plate is connected through condenser B to one aerial inductance tapping t, and the other tapping p is connected through contacts g, h to the back coupling coil G, variometer V, and earth. The valve thus oscillates with the aerial as the primary oscillatory circuit. When contacts e - - h are opened, and contacts a - - d are closed, the valve plate is connected through condenser B to a tapping q on a coil H, which is in a closed oscillatory circuit, comprising earth, resistance l, contacts c, d, condenser k, coil H, back-coupling coil G, variometer V and earth. The aerial W is connected through coils N, M and resistance l to earth, the resistance l thus forming a coupling-member between the aerial and the closed circuit. The frequency is the same for both connections, if the inductance capacity product for each of the circuits l, k, H, G, V and W, N, M, l is the same as that for the aerial circuit when direct-coupled. The inductance of the coil M is equal to the sum of the inductances of coils G, V. The indirect coupling may be used for transmission, but is particularly used for drying out the aerial if, owing to wet conditions, it will not oscillate when direct-coupled.
