Title: Improvements in and connected with stepped furnace grates
IPC: F23H7/06
Filed: 1921-07-23
Abstract: 176,727. Seyboth & Co., and Seyboth, F. July 23, 1921. Grates.-A stepped grate having movable elements arranged between fixed elements is provided with a number of successively-arranged movable grate bars which are composed in groups, the length as well as the number of strokes of one group being independent of the length and number of strokes of the adjacent groups. Figs. 1 and 2 show one arrangement, the grate being divided into three sections. Fixed bars a are supported by bearers c which rest on cross-bearers e1, e2 extending across the grate and supported by the side-frames C1' C2. The movable bars b pass between the fixed bars a and are supported on the carriage D2 in such a manner that displacement is impossible. Figs. 4 and 5 show the method of attachment of the bars b to projections f on the carriage D2, the rib x engaging the slot in the lug g of the bar. A gear-box is arranged to move the carriages supporting the movable bars to and fro. The shaft i, driven by a belt-pulley L, drives the ratchet O1 by means of an eccentric M and a pawl K1. The ratchet O1 in turn rotates the crank-arm T1 through toothed gears P1, P2, and an oscillating motion is imparted to the shaft M1 through a rod S1 and a lever y1. Levers N1 on the shaft M1 and a rod k2 attached to the pin h on the carriage D2 cause the carriage to reciprocate. The length of stroke is varied by making the pins of the cranks T1, y1. or N1 adjustable. The number of strokes is varied by means of a shield o1 adjusted by the hand-lever P, above the ratchet 0,. Each carriage D is operated in a similar manner, as also are the feeding-rollers. In one modification, the bars a, instead of being fixed, are mounted on carriages in a similar manner to the bars b, but are driven in the opposite direction. In another modification, the grate-bars of one or more sections of the grate extend lengthways instead of crossways upon the carriages; or the bars may be of serrated formation so that they intersect each other and prevent layers of clinker from being formed. A scraper-bar may be fitted between the upper surface of the moving bar and the lower surface of the fixed bar.

Filed: 1920-07-09
Abstract: 147,877. Wanderer - Werke vorm. Winklhofer & Jaenicke Akt.-Ges. July 15, 1915, [Convention date]. Addition to 147,876. Tabulating-mechanism ; tabulating key-actions. -The column-selecting and denominational tabu. lating mechanism described in the parent Specification is modified in the following manner. The section keys operate the locking-devices for the denomination stops by forcing pins between the locking-devices and a member controlled by the sections stops, the locking-devices being effective until the member releases the pin associated with the operative section key. In the mechanism shown in Figs. 1 and 3, the rods 35 operated by the section-key levers 7b carry pointed pins 37 adapted to be forced between a rack 31 and a bail 41 which engages bell-cranks 40 for locking the denomination stops 15 by engaging pins 15a thereon. The rack gears with a pinion 30 on a shaft 29 provided with a toothed wheel 23 for engaging section stops 22 on the carriage 3. A detent 26a engages a notched disk 25 on the shaft. The pins 37 are secured to blocks 36 arranged side by side within a recess in a plate 38. The denomination stops are carried by bell-cranks 12 pivoted on,the denomination-key lovers 6a, springs 13a being arranged between the bell-cranks and key-levers. The denomination-key levers actuate a bail 58 connected by a link 60 to the carriagereleasing device. When a section key is depressed, the associated pin 37 is forced between the bail 41 and the rack 31, and the bail moves the bell-cranks 40 into engagement with the pins 15<a> to lock the denomination stops. The rod 35 carrying the pin is retained in the raised position by a swinging bar 42 which catches a shoulder 35a on the rod. If now a denomination key is depressed, the carriage travels until a shoulder 31<a> on the rack passes the pin, whereupon the bail 41 is permitted by the pin to move forwards and release the locking-levers 40. Thereupon, the spring 13a raises the selected denomination stop into the path of one of the column stops 19. The forwards movement of the bail 41 releases the rod 34 from the bar 42 and permits the rod to descend.

Abstract: 945,841. Cigarette-making machines. MOLINS MACHINE CO. Ltd., D W. MOLINS, and J. A. MASON. June 7, 1961 [June 8, 1960], No. 20093/60. Heading A2C. [Also in Division F2] A knife feeding device for a rotating cut-off of a cigarette machine has a frictionally gripped sickle knife that is fed outwards by the rotation of a screw in a nut, which nut has fixed to it a flexible member (e.g. a chain) attached to an abutment on the inner end of the knife. The knife 20 (Fig. 4), frictionally held between plates 24 and 25, and supported by a block 23, is drawn outwards against a pair of springs 52 by a chain 50 attached at one end to an eyebolt 29 and at the other end to a nut 54. A bevel gear 56, fixed to a screw 55, mates with another bevel gear 57 fixed to a shaft 58 which rotates within the cutter bearing shaft. By means of gearing (Fig. 5 not shown) the speeds of these two shafts are arranged to differ by a slight angular displacement per revolution, and hence turn the screw 55 at a rate proportional to the difference between these two speeds. A Geneva stop mechanism 69, 70, on the end of a shaft 68, engages when the nut 54 reaches the lower end of the screw 55 and causes an overload clutch in the gearing (Figs. 6, 9, 10 not shown) to break so stopping further rotation of the screw 55. In an alternative arrangement, the chain 50 guided around four pulleys is attached to both ends of the nut 54 and to both ends of an abutment that replaces the block 23, this abutment having a small lug that enters a slot in the inner end of the knife 20. In another embodiment, the chain 50 is passed through the centre of the cutter bearing shaft, around pulleys 37 and 38 (Fig. 2) and is fixed to a slideable plate structure 39 in which a nut 44 is held captive. A screw 43 is driven by the machine drive via gearing within the box 11, a chain 47 and sprocket wheels 46 and 48 and a reduction gear 100. Specification 324,379 is referred to.
