Title: Folding apparatus for towels, napkins and the like
IPC: B65H45/101
Filed: 1949-02-03
Abstract: 661.570. Folding fabrics. MALOTT, C. S. Feb. 3, 1949, No. 3021/49. Class 42 (ii). In apparatus for folding limp, flat articles such as towels, napkins or pillow-cases, an article is advanced along a forming plate with a portion of the article supported in inclined position on the plate and a side wing of the article depending from a longitudinal edge of the plate, and the depending side wing is progressively folded inwardly and upwardly around the side of the forming plate by engagement with a stationary folding plate having a folding portion of twisted form which progressively changes from vertical disposition to an inclined disposition in.a plane parallel to the forming plate and which supports the side wing of the article during the whole of the folding operation. As shown, a towel &c. placed by the operator on conveyer belts 22, 23 is carried forward by belt 23 over a forming plate 71, the side wings of the article dropping down on both sides of the plate. The article passes beneath belts 28 which frictionally grip it against plate 71 and advance it thereover, the plate being grooved to assist sliding of the article. The depending wing portions of the article contact guide plates 72, 73 respectively, which are shaped to fold them, one after the other, inwardly and upwardly under plate 71. The advancing article successively trips switches 77, 78, which actuate an electronic timer controlling a cross-folding blade 39 according to the length of the article. As the longitudinallyfolded article continues to advance it crosses a gap 90 on to a pan 91; when the mid-point of the article is opposite gap 90, the timer energizes a solenoid 67 to produce one revolution of a shaft 42 and cause a cam 41 to advance folder blade 39 through gap 20 and force the article, centrally cross-folded, between folding rollers 29, 36. From rollers 29, 36 the article is guided by a plate 44 on to conveyer belts 45 and thence by a belt 48 to a stacking machine. Energization of solenoid 67 also produces one complete operation of the stacking machine, so that each article is stacked as the following article is cross-folded.

Title: Automatic slack adjusters for railway brakes and the like
IPC: B61H15/00
Filed: 1926-02-02
Abstract: 249,085. Svenska Aktiebolaget Broms regulator, (Assignees of Djurson, A. R. K.). March 14, 1925, [Convention date]. Force -transmitting mechanism; compensating for wear.- In automatic slack-adjusters for railway brakes &c. in which an adjuster screw is used to increase and decrease the play between the wheels and the brakes. the angle of inclination of the threads of the adjuster screw is so great that. the screw is not self-locking. The operation of the adjuster is controlled by two coupling members, one receiving rotary motion from the brake rigging, the other being connected to the screw. In a brake mechanism comprising a brake cylinder 1, Fig. 1, and brake levers 3. 4 connected by a rod 5 and having the brake rods attached to the lower ends of the levers, the slack adjuster 16 is mounted in one of the brake rods, near its connection with a brake lever 3. The movement necessary for the operation of the adjuster is obtained by a bell crank 6 mounted on the adjuster and coupled by a rod 9 to the lower end of the brake lever 4. The slack adjuster comprises the adjuster screw 12, Fig. 2, which may have multiplex threads fixed to a coupling socket 14 attached to the brake rod, and a nut 13 connected to the coupling socket 15 attached to the brake lever 3. A casing 18, which may be integral with the socket 15, encloses the two coupling members 26, 27. The coupling member 27 is connected to the nut 13 by a spindle 19 and a tube 16. The coupling member 26 is journaled about a reduced extension of the spindle 19 and has axially-extending ratchet-teeth adapted to engage with ratchetteeth on the member 27 under the pressure of spring 28. A forked crank 11 is secured to the member 26 and is connected to the bell-crank 6. Thus on operation of the brakes, the bell-crank 6 and rod 9 cause the coupling member 26 to be turned, disengaging projections 29, 30 and allowing the ratchet-teeth of the coupling members to engage. The nut 13 is consequently turned to reduce the slack unless this is normal, in which case the tension in the brake rigging due to the brake shoes coming in contact with the wheels will cause the member 27 to compress a spring 23 and come in contact with a friction surface 21 which stops its rotation. Excessive movement of the rod 9 being absorbed by a telescopic spring device 10. If the slack is too little, tension is produced in the adjuster before the members 26, 27 engage and the member 27 is withdrawn from contact with a friction surface 22, against the pressure of spring 23, allowing the nut 13 to turn on the screw 12 and so increase the slack. The spring 23 engages the member 27 through a ball bearing. The projections 29, 30 are provided with inclined surfaces on the sides facing each other so that they may glide easily on each other.

Title: Improvements in or relating to lighting fittings including support mechanisms for detachable reflectors
Inventor: HUBBOLD SYDNEY
IPC: F21V17/18
Filed: 1954-02-02
Abstract: 762,202. Supporting light reflectors. GENERAL ELECTRIC CO., Ltd. March 11, 1955 [Feb. 2, 1954], No. 3084/54. Class 75(2) [Also in Group XXIV] A support mechanism for supporting a detachable reflector of a lighting fitting in either of two positions comprises a lever 13 pivoted at one end on a pivot 9 of a fixed bracket 1 and carrying at its other end a link 15 with an eye 16 for engagement by a hook or the like on the reflector. Intermediate its length the lever 13 has a slot 21 housing a steel ball 22 which also co-operates with a cam recess 7 in a side surface of the bracket 1 formed by an outer web 5 and a central island 23. The island 23 has on its lower end a recess 24 and beneath this recess is a pointed projection 25 from the outer web 5. A spring 18 tends to maintain the lever 13 and the reflector carried thereby in one of two positions, one as shown with the ball 22 in the recess 24 and the other in which the ball lies in the top apex of the groove 7. Movement from the one position shown to the other is effected by pulling down the lever 13 so that the ball 22 engages the inclined side of projection 25 and moves to the right, and then releasing the lever to allow the ball to move up the right hand branch of groove 7 to the top apex. A further downward movement of lever 13 will cause the ball 22 to travel down the left hand branch of groove 7 until it engages the vertical face of projection 25 and, on release of the lever, to re-engage in recess 24. In the lower position of the lever 13 the reflector can be removed and replaced but in the upper position it is held securely in operating position by the spring 18. More than one of these support mechanisms can be used for a reflector. In a modified form a supporting member is vertically movable in guides and carries a pin which co-operates with a cam projection on a pivoted latch plate. The support is spring biased for its pin to engage either in a recess in the lower cam surface or to pass along the side of the cam to a position above the cam apex.

Title: Improvements relating to combined electric cut-outs and voltage or current regulators
IPC: H02J7/22
Filed: 1930-01-30
Abstract: 347,299. Electromagnetic switches. LUCAS, Ltd., J., Great King Street, Birmingham, and ROBINSON, C. E., 403, Princes Gardens, West Acton, London. Jan. 30, 1930, No. 3182. [Class 38 (v).] A combined cut-out and voltage regulator for a dynamo and storage battery comprises an electromagnet having an armature carrying a contact and co-operating with two superposed spring blades carrying two contacts, so that the first movement of the armature closes a circuit and further movement breaks another circuit. An electromagnet a has an armature b carried by a spring c and having an extension d. A stop f limits the upward movement of the member d. A double spring member is mounted between the parts band d, and comprises a spring g and a stiffer spring h, both held by a screw k. A screw n and knife-edge m are provided for altering the stiffness of the spring h. As used in connection with a dynamo charging a battery, the electromagnet a is excited by the dynamo and when the dynamo voltage reaches a predetermined value the armature b is attracted to cause the contact e on the member d to touch the contact i on the spring g thus switching in the battery for charging. On a further rise in voltage, the member d moves down further and the stud j on the spring g moves the spring h. This breaks contact between contacts q and r and inserts resistance into the dynamo field circuit.
