Title: Mechanisms and method for making boxes with attached handles and the like
IPC: B31B50/86
Filed: 1946-04-26
Abstract: 643,649. Making boxes. BERGSTEIN, S. April 26, 1946, No. 12711. [Class 18] Boxes of the kind described in Specification 524,924 have handles 14 attached to the main panels 1, 5 by adhesive. The handles meet over the top walls 3, 7 of the box and are locked together by bending their cut-out portions 14c to one side. The boxes are formed on machines substantially as described in the above Specification but having devices for applying the handle blanks. In one embodiment, the handle blanks 14 are fed in on both sides of the box blank conveyer 18 by two feeding and glue applying devices pivoted at 31 and periodically raised clear of the box blanks by cams 34 and followers 33. In each device, a feed wheel 36 takes handle blanks singly from a hopper 35 passes them to conveyer belts 37, 41 for gluing by a roller 46 and delivery to a platform 47 below the path of the box blanks. Pressure wheels 48, 49 force the handle and box blanks together and the joined blanks may be passed, as shown, through rollers 50, 51 to ensure adhesion or may go direct to a folding mechanism 25 where sweeps 26 turn over the flaps 3, 7 and the free portions of the handles to lie flat on the main panels 1, 5. The completed collapsed box is passed out to a stacking conveyer 28. An alternative device for feeding handle blanks comprises, on each side of the box blank conveyer, a hopper 73 from which the blanks 14 are fed to a further hopper 81, Figs. 8, 9. From the hopper 81 the blanks are fed by a conveyer 82 past a glue roller 89 to a platform 91. The platform 91 and a member 115 are forced towards each other by toggle mechanisms to press the blanks 14 against the underside of the box blanks. The box blanks' motion is halted during the period in which handle blanks are being attached by dividing the box blank conveyer just before the handle attaching mechanism. This conveyer thus comprises two separate chains 101, 104, moving at the same speed but having blank engaging lugs at different intervals. The box blank is carried by the chain 101 to the handle applying position and is halted until engaged by a lug on the chain 104.

Title: Improvements in locking devices for pivotal members
IPC: B61L19/14
Filed: 1944-08-16
Abstract: 573,005. Locking levers and rods. B.T.L. PRODUCTS, Ltd. [formerly BEN TRANSPORT, Ltd.], and TEGERDINE, G. E. Aug. 16, 1944, No. 13260/43. [Class 80 (iii)] Relates to locking devices for pivotal or rotary members of the kind in which a controlling member, e.g. a lever, may be operated to move a controlled member, e.g. a lever, in either direction about its pivot axis, but wherein the controlled member cannot be operated in either direction without the intervention of the controlling member. According to the invention, means are provided for releasably retaining the controlling member in a neutral position relative to the controlled member. A bracket 1, Figs. 1, 2, 3, carries a fixed pressure ring 2 having an end wall 3 integral with a boss 4 through a bore 5 of which is passed a clamping bolt 6. On the boss 4 is rotatably mounted a locking cam 7 which has opposite circular portions 8, 9, Fig. 3, concentric with the inner surface of the ring 2, these portions being connected by two convex cam surfaces 10, 11. The controlled member consists of a lever 13 which is secured to the cam by screws 14 and has a pair of parallel straight sides or flats 15, 16, Fig. 1. In each of the gaps 18, 19 between the surfaces 10, 11 and the internal surface of the ring 2 are a pair of rollers 20-21, 22-23 urged apart by a spring 24. The controlling member is a lever 25 which carries shoes or segments 26, 27 adapted, on initial movement of lever 25, to engage and release the appropriate rollers from their locking position. The lever 25, in the form of a spanner Fig. 1, surrounds the end of the lever 13 with slight clearance to permit of the initial movement to release the rollers. According to the invention, the cam has diametrically-opposite recesses 34, Fig. 3, each containing a spring- loaded ball 35 adapted to enter a recess 37 in the interior surface of the ring 2 in order to retain the lever 25 in a neutral position with the ends of the segments 26, 27 clear of the rollers, to prevent accidental release thereof due to vibration. In modifications, the retaining device is described in connection with (1) a locking device as in Figs. 1-3 but having only one pair of locking rollers such as 22, 23, Fig. 3, (2) a locking device having only one roller in each of the gaps 18, 19 of Fig. 3, (3) two locking devices as in Figs. 1-3 arranged in tandem, and (4) a shaft rotatable directly by a hand wheel. A pressure-distributing shoe may be inserted between each locking element and the inner surface of the pressure ring.

Title: Improvements relating to looms with automatic cop loaders
IPC: D03D51/34
Filed: 1951-06-06
Abstract: 705,296. Automatic cop changing in looms. SHIMWELL, D: W. June 3, 1952 [June 6, 1951], No. 13435/51. Class 142(2) In a loom for weaving twill cloth cop changing is delayed so that the first pick of the new weft may be laid in the same shed as the broken weft. When a weft fork on the replenishing side of the loom detects absence of weft, and the feeler mechanism described in Specification 632,245 indicates exhaustion of weft in the shuttle, the shuttle runs empty for the two succeeding picks and is then loaded. When the weft fork on the driving side detects weft failure and the shuttle is exhausted, the shuttle run empty for the five succeeding picks and is then reloaded. When the feeler mechanism detects exhaustion of weft in the shuttle, a rod 16 raises a pawl 17 from engagement . with a step 22 of a tongue 20 so as to engage an upper step 25, the tip of tongue 20 thus being brought level with a pawl y. If the weft fork c at the driving side of the loom detects weft failure, the weft fork slide e is moved forwards and tongue 20 engages pawl y which is moved forwards, immobilizing the take-up motion, rendering the weft fork mechanism on the loader side inoperative, and lowering ,a twill pawl z into engagement with a pin 52 on slide e. When the empty shuttle returns to the driving side pin 52 engages a notch 51 in pawl z and moves it forward. On the shuttle again returning to the driving side, pin 52 engages a notch 53 at the end of pawl z which is now able to move a lever w sufficiently to operate a cop loader rod p, so that a new cop is inserted when the shuttle arrives at the loader side. The take-up motion and the weft knock-off motion also resume their normal working positions. If the weft fork at the loader side of the loom detects weft failure the weft fork slide is moved forwards and a tongue g (raised by a mechanism similar to that actuating tongue 20) engages and moves an arm h which causes the twill pawl z at the driving side to move so that its notch 53 is ready to be engaged by the pin 52 on the weft fork slide. On the shuttle being picked to the driving side, the pin engages notch 53 and moves the pawl sufficiently to cause lever w to actuate the loader rod p. On returning to the loader side replenishment takes place. If the shuttle is not exhausted, but the weft fork at the driving side indicates weft failure, tongue 20 is in its lower position when slide e is carried forwards, and the tongue engages an arm 40 actuating a stop mechanism. If the loom is required for weaving plain cloth a lever x, to which the pawl y is pivoted, is fixed to lever w by screwing in a stud 58, and the weft fork at the loader side of the loom is put out of action. Specification 637,899 also is referred to.
