Title: Improvements in and relating to filling machines for powder or dry goods
IPC: B65B43/52
Filed: 1930-09-27
Abstract: 355,987. Filling powder into cartons &c. LEADLEY, J. W., 13, Punstock Road, Darwen, Lancashire. Sept. 27, 1930, No. 28979. [Class 94 (i).] Relates to a machine for filling cartons &c. with powder and comprising a chamber b of flattened oval form having filling nozzles h depending from its base in spaced parallel lines and communicating with a channel or space b<1> defined by the wall of the chamber and an endless belt d, the belt d being provided with vanes d<1> adapted to carry the powder past the nozzles, through which it falls when they are opened by their controlling means. According to the invention, cartons &c. placed on an endless belt j are divided by a V-shaped deflector v into parallel rows arranged at the edge of the belt beside tables k, and when a number corresponding to the filling nozzles has been fed forwards, the leading carton operates a switch, which controls the motor o of a pair of cam shafts o, so that cams on the shafts, operating through levers s<3>, links s<4>, and levers s<2> displace outward rods s<1> carrying rails r which transfer the cartons to the tables k ; cams n acting through levers m<2>, links m<1> and levers m raise the tables k to the filling nozzles and keep them there while further cams displace discs t in the chamber b to uncover the nozzles. On completion of the filling the operations are reversed and the motor p is switched off by projections on one or other of the links. If cartons with closing flaps are to be filled double rows are fed to each side of the chamber b and treble rails not only transfer the cartons but move upwards to dispose the flaps about the nozzles. Specification 353,594 is referred to.

Abstract: 664,231. Resilient mountings. THIRY, L. F. Nov. 18,1949 [April 8, 1949], No. 29583/49. Class 108(iii) [Also in Group XXXIV] The invention relates to a method of manufacture of flexible pivotal joints of the kind comprising rigid inner and outer members 1, 2, Fig. 1, having disposed therebe t w e e n under radial compression, a rubber bushing 3, the central portions of the rigid members 1, 2 being subsubstantially cylindrical while the end portions of both members are of reduced diameter, the bushing being compressed between the rigid members at both the central and the end portions thereof. According to the invention, the diameter of the bore of the central portion of the rubber bushing 3 is increased during assembly as compared with its diameter in the free state, in addition to the bushing being radially compressed and axially elongated between the inner and outer members 1, 2, the diameter of the end portions of the outer member 2 then being reduced by a swaging or like operation. The joint is assembled by inserting the bushing 3 via a tapered tube 9a, Fig. 2, into the member 2 and then forcing the member 1 into the bushing 3 behind a tapered leader member (not shown). The ends of the member 2 are then reduced by means of swaging tools 11; or by means of press tools 10 applied simultaneously at each end of the joint. Before assembly the bushing is as shown in Fig. 3; it may, however, be formed at each end of its bore with inwardly projecting annular portions, Fig. 4 (not shown). The dimensions of the parts before and after assembly are preferably such that (D6-D3) is less than (D1-D5). The ends of the member 1 may be threaded as shown, or may be splined and this member may be tubular and internally splined. In a further construction, Fig. 5 (not shown), the member 1 is tubular and held on an inner shaft between a nut and collar on the shaft. One of the members between which the joint is mounted, is secured by a nut to an extension of the shaft on the other side of the collar. The invention may be applied to resiliently mounting tyres on rail-vehicle wheels (see Group XXXIV). According to the Specification as open to inspection under Sect. 91, the ends of the member 2 may be reduced at one end before assembly of the joint. This subjectmatter does not appear in the Specification as accepted.
