Title: Improvements in bed-reciprocating motions
IPC: B41F3/58
Filed: 1936-06-03
Abstract: 476,230. Gearing for converting rotary into reciprocating motion. AMERICAN TYPE FOUNDERS, Inc. June 3, 1936, Nos. 15566 and 15567. Convention dates, Sept. 21, 1935 and Oct. 24, 1935. [Class 80 (i)] [Also in Group XVI] A bed-reciprocating mechanism which is especially applicable to the beds of cylinder printing-machines of the continuous revolution type is constructed to produce a substantially constant velocity of the bed during a considerable portion of its cycle of movement by imparting to the bed a movement which is compounded of a plurality of harmonic motions, by. means of a plurality of driving elements movable without retracement along dissimilar non-circular cyclic paths in such a manner that the elements complete their separate cycles in the same time, the elements being maintained in constant operative connection with the bed. As applied to a printing- machine the bed 15 of the machine is driven by a travelling gear 65, Fig. 14, which engages a fixed rack 63, and a rack 64 on the underside of the bed. The gear 63 is given a motion compounded of the motions of two reciprocating cross-heads 50, 51, Figs. 10 and 11, which are formed with vertical slots 80, 81 respectively engaging blochs 78, 79 pivoted to crank-pins 76, 77 fixed to the gear 65. The cross heads 50, 51 are reciprocated by crank pins 45, 48 which are given motions in hypotrochoidal paths by means of gear wheels 28, 30 which are driven by gears on the main shaft 20 geared also to the gear 26 of the impression cylinder 14. One hypotrochoid is of curtate and the other of prolate form. The wheels 28, 30 carry on their internal surface pinions 40, 42 which are caused to rotate in contact with fixed internal gear wheels 36, 37, the gear ratios of the wheels 40, 36 being 1 to 3 and of the wheels 42, 37 being 1 to 4. The crank pins 45, 48 are mounted on crank discs 44, 47 on the shafts 39, 41 of the gears 40, 42. The cross-heads 50, 51 are formed with slots 69, 70 which serve as guides for the bearings of the gear wheel 65 and with slots 53, 57 to permit movement of the cross-heads relatively to the driving-shaft 20. The bed is guided by slots 16 in the machine frames 12 in which the cylinder 14 is mounted but the bed may be mounted in other ways. In a modification in which a similar arrangement of gearing is employed but in which the two hypotrochoidal motions are of prolate form owing to different gear ratios and radii of. the crank pins, one of the cross-heads is fitted with a rack which gears directly with the travelling gear wheel for driving the bed. The other cross-head transmits motion to this travelling gear wheel in a manner similar to that described in connection with the first construction.
