Title: New or improved string extractor means of or for baling apparatus
IPC: A01F15/12
Filed: 1948-08-19
Abstract: 640,772. Baling-presses. JONES, D. T., and Jones, G. Aug. 19, 1948, No. 21860. [Class 94 (i)] In baling - presses comprising a chamber 1 in which material is compressed by a ram 4, and knot-tying devices 5 associated with needles 6 which are swung downwardly through slots 3a in the breast plate 3 and floor of the chamber to position string in the path of the incoming material and are subsequently swung upwardly to carry the string around the completed bale, means are associated with each device 5 whereby a length of string is extracted from the string containers after completion of one bale and before the commencement of the next bale to obviate the necessity of string being pulled between the completed bale and the new bale during the making of the latter. As shown in Figs. 1 and 2, a pair of arms 12, formed with feet 12a, are keyed to a shaft 10 which carries follower rollers 15, 16 engaged by cams 13, 14 on a parallel shaft 7 actuating the devices 5, this shaft being driven by a spur gear 17 through a clutch which is arranged to be engaged and disengaged at intervals to cause the shaft to make one complete revolution. The contours of the cams 13, 14 are such that during the knotting operation the arms 12 are maintained in a retracted position so that the string ends a, b held by the retainers 5a of the devices 5 are positioned correctly, but after the knotting is completed and simultaneously with the downward movement of the needles 6 the arms are swung upwardly by the action of the cam 13 to extract a length of string equal to the length of a completed bale. During the making of the new bale, string for the bottom face is drawn over the needles 6 and the arms 12 are pulled downwardly against the action of a friction device 30 arranged in series with a spring (not shewn), the spring taking up slack in the string during the return strokes of the arms. The arrival of the arms at their retracted position is arranged to engage the clutch between the shaft 7 and gear 17, and for this purpose an arm 28, Fig. 4, on the shaft 10 is coupled by a chain 27 to a spring-loaded lever arm 24 keyed to a shaft 22 which carries a detent 21 adapted to engage a spring-loaded pawl 18 pivoted to a driving dog 19 keyed to the shaft 7. The detent normally maintains the pawl out of engagement with a step 17b in the flange of the gear 17, but is rendered inoperative by rotation of the lever 24 under the action of the chain 27 which is tensioned as the arms 12 reach their retracted position. The cam 14 operates to hold the arms 12 in their retracted position during the knotting operation and also prevents free movement of the arms in their raised position; the cam 13 is arranged to effect a slight initial raising of the arms during the knotting operation to position the string clear of the devices 5. The arms 12 may be counterbalanced or spring-loaded instead of, or in addition to, being camactuated. Specification 615,876 is referred to.

Abstract: 448,661. Time-indicating mechanism. ELECTRIC AUTO-LITE CO., and LINER, J. I., Champlain Street, Toledo, Ohio, U.S.A. Aug. 7, 1935, No. 22322. [Class 139] Time-indicating mechanism includes a member 38 with time-indicating marks thereon which is moved continuously and regularly, a second member (shutter) 63 associated with the movable member for displaying only a selected time indicating mark, means for moving the two members 38, 63 at the same rate and means 81, 82 for causing periodically (e.g. once an hour) a relative movement between the two members. An hour disc 38, minute disc 42, and seconds disc 55 are rotated through gearing from an A.C. synchronous motor ; the hour and minute discs are partially exposed at openings 35, 50 in the fixed plate 11 and the seconds disc has an arrow 58 rotating in opening 60. Between the hour disc 38 and plate 11 is a shutter 63 which is pivoted coaxially with the hour disc and has an opening 68 sufficient to expose one hour numeral. An arm 70 pivoted at 72 to shutter 63 is pressed inwards radially by spring 76 and has a lug 83 which coacts with twelve shoulders 84 on the hour disc so that the shutter is carried round clockwise with the hour disc. When this shutter 63 at the end of an hour reaches the end of its travel, a cam 82 on the minute disc 42 meets lug 81 on arm 70, forcing the latter out radially so that its lug 83 clears shoulder 84. A spring 85 thereupon moves the shutter 63 rapidly counterclockwise one twelfth of a revolution until lug 83 meets the next shoulder 84 and exposes the next hour numeral. During the hour that the exposed numeral moves from left to right of window 35, a mark 91 on the hour disc reads against graduations 90 on the plate 11 to give a reading of the minutes elapsed since the beginning of the hour. To prevent the shutter 63 from travelling too far clockwise, a lug 89 on it meets a fixed stop 88.
