Filed: 1925-07-08
Abstract: 259,308. Burn, L. July 8, 1925. Reversing-gearing comprising two trains each with double cranks cooperating with a crossedslotted disc and operated by applying two brushes alternatively as described in Specification 14931/14, is controlled by selector means adapted to apply a brake to the driven member when in neutral. As applied to lifting and hoisting, the load is prevented from running back when changing. A driving-shaft 11 carries one pair of cranks 13 coacting with a crossed-slotted disc 14 secured to an eccentric shaft 15, which carries cranks 19 engaging a second slotted disc 27 fast on driven shaft 21, which is in line with the shaft 11. The shaft 15 is carried in a revoluble frame 17, and when this is held by a brake 26, the shaft 21 is driven forwardly at quarter speed, a convenient speed for lifting. When the disc 17 is allowed to turn, and the shaft 15 kept from turning on its axis, the shaft 21 is driven reversely at half speed, a convenient speed for lowering. This is effected by releasing the brake 26 and applying a brake 24 to a loose disc 22, which is connected by wabble cranks 23 to the disc 14. These brakes are controlled by suitable cams upon a shaft 25 which is geared to a hand-lever 35, the extreme positions of which correspond to forward and rearward driving. When the lever 35 is nearing neutral, a third cam applies a brake 28 to the driven disc 27. The system is balanced by a disc 39 on the opposite side of the frame 17 to the disc 14, and by masses 40 upon the frame itself.

Title: Improvements in methods of and apparatus for feeding cigarettes and articles of similar shape
IPC: B65B19/10
Filed: 1924-07-23
Abstract: 238,355. Molins, W. E. July 23, 1924. Packeting cigarettes.- Relates to apparatus, for feeding cigarettes and articles of similar shape, and of the type wherein the cigarettes &c. pass from a hopper into substantially vertical channels, for instance as described in Specification 216,326, being ultimately carried to a packeting or other machine. As shown, the cigarettes pass from a hopper in 1, Fig. 2, between vibrating vanes 2 on to a sloping table 3. The gap between the bottom of the vanes and the table is approximately equal to half the diameter of a cigarette. Bars 4, Fig. 1, on chains 4<a> pass through the gap and remove successive layers of cigarettes to the left. The table 3 is gapped at 3<a> to allow dust &c. to fall through and bevelled at the forward edge A. The cigarettes pass beneath a cover plate 13, which may be transparent, and fall in superposed rows, into a channel B in which a plunger, or members 19 of an endless conveyer such as is described in Specification 13956/15 operate to move the bunches to the left. Before passing from beneath the cover 13 the cigarettes are laterally compressed by converging side guides, and when in the channel B, a sliding block 14, Fig. 5, is operated by a cam and link 42 so as to project through the sides 11 of the channel. A presser plate 16 is simultaneously lowered by the action of a cam 48, on the block, upon a bell crank lever 46 carrying the pivot 17<a> of the arm 17 of the plate. A swinging plate 18, Fig. 1, is raised from the positions shown in broken lines by the passage of a bunch of cigarettes. When the cigarettes are to be packed in boxes of the slide and bell type, the compressing apparatus may be omitted. The bars 4 are arranged on the chains 4<a>, so as to allow time for the treatment of the predetermined number of superimposed rows in the channel B. If it is desired to pack cigarettes in bunches having different numbers of cigarettes in the rows, a bell crank lever 26, Fig. 2, is operated from a cam 28 to cause a plate 27 to project into a vane slot and to prevent a cigarette from falling to be carried away by the next feed bar 4. The arrangement may be duplicated, to prevent a cigarette from each end of a row from being fed, and the channel may be fitted with longitudinal strips to hold in position those rows which have fewer cigarettes. The bars 4 and the members 19 may be continuously or intermittently moved, or may be replaced by reciprocating members.
