Title: Improvements in mechanism for splitting rubber tape into its component threads
IPC: D02H13/16
Filed: 1938-04-28
Abstract: 494,081. Rubber threads ; braiding-machines. EASTHAMPTON RUBBER THREAD CO. April 28, 1938, No. 12689. Convention date, May 13, 1937. [Class 70] [Also in Groups VIII, IX, and XXV] Tape composed of rubber threads adhesively united is split into its component threads by drawing it through splitting means such as a comb while in a stretched and elongated condition attained by feeding it to the splitting means by a set of rolls imparting a slower speed than the drawing means. Tapes 3, 4 are led from containers 5 through tension devices 6, between driven feed rolls 7, 8, are split into threads by being drawn through a reed or comb 10 by feed rolls 11, 12 driven faster than 7 and 8, and the threads are wound on a beam or beams B. One or both of each pair of feed rolls is made of or surfaced with resilient material such as rubber, and the gripping pressure may be adjusted by means of thumbscrews 24. Part of one tape may be diverted, e.g. into a container 5<1> before the reed 10, if all its threads are not required. The threads may be fed directly to a textile-fabricating machine, e.g. a loom, braiding-machine, or thread-covering machine connected by gearing &c. to the splitting apparatus so that a definite relation holds between the speed of the two pairs of feed rollers and of the further machine, and desired tensions are attained at each stage. Alternatively, the second pair of feed rollers may be replaced by the take-up or drawing rollers of the loom, braiding-machine, or covering machine, the take-up rollers and first feed rollers being connected by gearing &c. to give a desired speed ratio. Two reeds may be used, the first subdividing the tape into groups of two threads, the second dividing these into single threads. The tape may be split by leading it between two closely mounted parallel rods &c. and guiding alternate threads from this point in widely divergent directions. Specification 470,448, [Group IX], is referred to.

Title: Improved gear for raising, lowering and controlling the presser of tea rolling machines
IPC: A23F3/12
Filed: 1927-05-12
Abstract: 295,431. Sutton, L. H. May 12, 1927. Tea, rolling.-In a tea-rolling machine of the kind in which the rolling box 31 containing the leaf is given a horizontal eccentric motion by cranks or eccentrics 3, and in which a presser 32 is vertically adjustable in the box 31 by screw mechanism 33, the presser raising and lowering gear is driven from one of the cranks or eccentrics 3 and includes a rotating shaft 9 which actuates the screw of the presser through chain and wheel gearing 22, 38, 39, 40, 41. The shaft 9 is adapted to be reversed in direction of rotation according to whether raising or lowering is desired. In the construction described, the shaft 9 is carried in bearings 8 on a bracket 7 secured to a flange 1 on the box 31. A bevel wheel 5 mounted in a bearing 6 in bracket 7 and connected to and rotating with a crank 3 engages two bevel wheels 10 loose on shaft 9. A clutch 11 keyed to shaft 9 cam be moved into engagement with either pinion wheel 10 to lock it to the shaft which is then rotated in the desired direction. The clutch 11 is operated by a shaft 15 slidable in shaft 9 and rotating at its outer end in a member 16<x> supported by arms 18 pivoted on a shaft 19 and having an operating handle 18<x>. One arm 18 has an extension 18<Y> engaged by a spring-pressed plunger 20 which tends to retain the handle 18<x> in the neutral position and returns it thereto when released from either operative position. A sprocket wheel 22 of the chain drive for rotating screw 33 of the presser 32 is secured, through spring-pressed clutch mechanism 23, to the other end of shaft 9. The clutch mechanism 23 may, however, be disposed at another point between shaft 9 and screw 33. In place of clutch 11, more than one clutch may be used, e.g. one for each wheel 10. To produce a record of the working, shaft 19 is connected through lever and link mechanism 24 to a rod 25 sliding in a bracket 26 and projecting into a casing 27. The lower end of rod 25 carries a spring-pressed pencil 28 working on a chart on a disc 29 which is constantly rotated, e.g. by gearing from wheel 5.

Abstract: 1454651 Apparatus for closing boxes/conveyers comprising endless belts and rollerways PRICE & KNOTT MFG CO Ltd 21 March 1974 [6 April 1973] 12750/74 Headings B8C and B8A An apparatus for gluing and closing boxes of the same and different heights comprises a pivotal arm 34 for sensing the height of the box at a sensing zone Z and causing adjustment of the height of a glue applicator 68 and flap folders 60, 70 which are mounted on a vertically movable frame 50 at a gluing and closing station G. The width of the box is also sensed at the zone Z by sensors (33) Fig. 8 (not shown) which move inwardly with conveyer belts 30 until the box sides are contacted. The spacing between conveyer belts 46 at the gluing and closing station G is then adjusted using further sensors (102, 104). Fig. 8 (not shown) which compare the positions of the conveyer belts 30, 46. If the sensed dimensions of the box at the zone Z are the same as those of the box passing through the station G, the frame 50 stays in the same position and the box immediately admitted to the station G. If the boxes at the zone Z and station G have different sensed dimensions, the box at the zone Z is held until the preceding box has left the station G. The belts of each pair of belts 30, 46 are moved together and apart in equal amounts by a respective piston and cylinder assembly (80, 90) Fig. 8 (not shown) connected to a respective endless cable (76, 86) Fig. 3 (not shown) to which the conveyer belt wheels (32, 48) Fig. 2 (not shown) are also connected. The top and bottom of the box are closed at the station. In operation as a box is detected entering the sensing zone Z an input gate 16 is raised and the belts 30 are moved from a fully spaced-apart position to engage and convey the box until it strikes a stop plate 20. The bottom side flaps are allowed to fall open by lowering box supporting rollers 10 and raising a central rail 26 which supports only the front and rear bottom flaps. The dimensions of the box are sensed and the height of the frame 50 and the spacing of conveyer belts 46 are adjusted, if necessary before the stop plate 20 is lowered. As the box enters the station G it is supported by a central rail 40 with its side flaps still open and the folder 60 which is a rotatable helical rod, folds down the rear top flap. Lines of glue are applied to the top and bottom front and rear flaps by applicators 66, 68 controlled by box detecting sensors (118, 120, 122, 124) Fig. 8 (not shown). The sensors (118, 124) which are mounted on the cable (86) for moving the conveyer belts (46) together and apart, control the applicators 66, 68 so that adhesive is not applied to the box in the regions between the front and rear flaps. The bottom and top side flaps are then closed by a pair of upwardly angled lower closers 42 and upper closing rails 70, respectively.
