Abstract: 653,247. Tape dispensers. KRUEGER, T. H. July 30. 1947, No. 20693. Convention date, July 16, 1946. [Class 18] A measured length of pressure sensitive adhesive tape is withdrawn from its roll and subsequently withdrawn from the dispensing device housing the roll. The tape is led from its supply roll 20 round rollers 76 and 60 on to a movable table 40. The roller 76 is mounted on a pivoted plate 80 biassed upwardly by a spring 84, and the roller 60 is mounted on the support for the table 40 which support is pivoted at 34 to the casing of the device and is held in a raised position by a spring 50. A pawl and ratchet mechanism controls the rotation of the roller 60 in one direction. The tape is fed so that the non-tacky surface engages the rubber roller 76 and the tacky surface adheres to the roller 60 with the effect that upon movement of the table 40 in a downward direction the roller 60, held stationary by the pawl and ratchet mechanism, withdraws the tape from the roll and a length extends between the two rollers 76 and 60. Upon release, the table moves upwardly under the action of the spring 50 and at the same time the plate 80 swings the roller 76 in the same direction due to the influence of the spring 84. When it is desired to withdraw the tape from the device, the end of the tape is grasped and pulled, under which action the roller 76 swings downwardly on the plate 80 until it engages a stop 44 whereupon the tape is severed by a cutter 90 positioned on the edge of the table 40. Alternatively, the roller 76 may be mounted on the casing, the tape withdrawn from the roll forming a loose bight within the casing when the table is released to return to its initial position after its operation. Predetermined lengths of tape may be withdrawn by altering the position of a table stop 46 within a series of sockets 48. The spindle supporting the tape may be of the kind described in Specification 631,462 and may be provided with means for overlapping the edge of the core to prevent the tape from extending in the form of a cone. 653,283. Bottle filling and capping machines. U.D. ENGINEERING CO., Ltd., and TAYLOR, J. C. March 12, 1948, No. 7641. [Class 125(ii)]  A bottle filling and capping machine having vertically reciprocable heads 15, 31 comprises a rectilinearly travelling conveyer 10 a rotatable disc support 36, 37 disposed beneath each machine and spaced from one another and from one side of the conveyer, a star wheel 18 overlapping the conveyer and the disc 36 beneath the filling machine, a second star wheel 17 overlapping parts of the two rotatable discs, a third star wheel 19 overlapping the disc 37 beneath the capping machine and the conveyer, guide means 49 encircling those sides of the three star wheels most adjacent one another and overlapping the conveyer beneath the first and third star wheels and also part of both rotating discs, and means for rotating the discs and star wheels in synchronism with the conveyer. The bottle filling head 20 has valve controlled outlets 15 and is rotated by means of hub 22 and hollow shaft 16. The outlets 15 are moved vertically by the brackets 27 on arms 26 which have rollers 25 engaging a fixed cam disc 23. The capping head 21 is similarly rotated by shaft 28, and carries spindles 30, 31 which are reciprocated by rollers 32, 33 engaging fixed cam tracks on member 34. Disc 36 is secured to shaft 16, and disc 37 to shaft 28, and sprocket wheels 38, 39 on the shafts are driven by an electric motor through the endless chain 40. Gear wheels 41, 42 are secured to shafts 16, 28 respectively. A pinion 43 on spindle 44 of the star wheel 19 engages pinion 45 on shaft 46 of the star wheel 18 which is driven by the gear wheel 41 through gearing 54, and pinion 47 on shaft 48 of the star wheel 17 engages gear wheel 42 so that the discs and star wheels are rotated in synchronism. The guide member 49 has part circular guiding faces 50, 51, 52. In place of spindles 44, 46, 48 being driven by toothed gearing they may be driven by chain 40 encircling sprockets on those shafts as well as the sprockets on shafts 16, 28. Specification 513,260, [Group XVII], is referred to.
