Abstract: 1,207,646. Tongs for handling rolls of sheet metal. COCKERILL - OUGREE - PROVIDENCE. 16 June, 1969 [27 June, 1968], No. 30376/69. Heading B8H. Tongs for lifting rolls of sheet material 12, Fig. 1, and turning the rolls to the position shown in Fig. 2, and vice versa, comprise fixed and movable jaws 11, 21 suspended by pairs of rods 9, 10 from the apices of a pair of pivoted triangular plates 8. The latter are supported from a lifting plate 1 by a pair of rams 2, 3 which charge an hydraulic accumulator 34 when the tongs are lifted. The jaws are rotated anticlockwise, to the position shown in Fig. 2, by the extension of a pair of rams 27 which act between points 3b on the triangular plates and extensions 9a of the rods 9. This causes anticlockwise rotation of the triangular plates 8 about a pivot 6, and consequential rotation of the jaws. To close the jaws on a reel a ram 24 is extended to turn a bell-crank 15, which pivotally supports the jaw 21, anticlockwise about a point 16, against the resistance of a stack of spring washers 22. The pivot point 16 is next moved by a drive spindle 18, turned by an hydraulic motor 19, until the jaw 21 contacts the reel 12. Contraction of the ram 24 now permits the springs 22 to urge the jaw into gripping contact with the reel. An oil reservoir 33 is provided and all the rams are operated by the accumulator and controlled by remotely operable valves.

Abstract: 356,001. Preparing fibrous materials for moulding. OESTERREICHISCH AMERIKANISCHE MAGNESIT AKT.- GES. and ERDMANN, K., Radenthein, Carinthia, Austria. Oct. 10, 1930, No. 30414. [Class 87 (ii).] In manufacturing building elements from fibrous material impregnated with a binder, for example, wood wool impregnated with sorel cement, the wool or the like is fed into a vertical shaft 1 from which it is drawn by the compression rollers 2, 3 and delivered in the form of a loose rope to a bath 7 containing the cement or the like. Rollers 9, 10 squeeze out superfluous liquid and also stretch the rope by rotating faster than the rollers 2, 3. The rope passes from the rollers 9, 10 to moulding- machines (not shown). One or more sets of pivoted forks 15, reciprocated by the crank 16, remove portions of the rope and throw them on to the feeding conveyer of the moulding-machines. This operation redistributes the particles in accordance with their weights, the result being a more uniform band of moulding material. Both upper rollers 3, 10 are mounted adjustably, the former on a pivoted arm 4 and the latter on an adjustablyweighted arm 13. One of the rollers 9, 10 preferably is of greater diameter at the ends than at the middle.

Title: Improvements in or relating to pleating machines
IPC: D06J1/02
Filed: 1926-12-02
Abstract: 285,595. Miller, J., and Hudson, G. R. Dec. 2, 1926. Pleating-machines.-The stroke of the pleating knife or knives is varied automatically or mechanically together with the pleat fixing rollers, and the speed of the machine may be correspondingly varied. As shown, the knives and rollers are of ordinary type, the knives being mounted on carriers the reciprocation of which is determined by a pivot a, adjusted by a spring- pressed pivoted quadrant lever b, and the intermittent feed of the rollers is similarly determined by a pivoted spring-pressed quadrant c and pawl c<1>. Freely sliding rods d are operated by two stepped cylindrical cams f for the knives and one stepped cylindrical cam g for the rollers. The cams are feathered on corresponding guide rods f<1>, g<1> rotated by pinions k, k<1> respectively, engaging racks l, l<1> actuated from a cam wheel m by means of spring-pressed rods. The cam is driven by chain gearing m<1>. The stepped cams are mounted on a beam h receiving vertical motion by links i and cams j. A size setting wheel carries stops which come into the path of the reciprocating racks and determine thereby the setting of the machine. The racks slide side by side and are capable of being locked together by a locking pin t actuated by the beam h. One stop on the size setting wheel determines the stroke of the pleating knives, and an adjacent stop corresponding to the pleat previously made actuates the rollers. Subsequently the locking pin locks the racks together. Thereby it is ensured that in a change of pleats the travel of the setting rollers corresponds to the pleat previously formed. A series of loose pulleys v, w, x, and clutch mechanism enables the speed of the machine to be varied. The variable speed may be obtained electrically or mechanically. Specification 237,505 is referred to.
