摘要： 358,523. Manhole frames and covers. STONE & CO., Ltd., J., Deptford, London, and WELLS, A., Hay Tor, Daines Close, Thorpe Bay, Essex. July 9, 1930, No. 20812. [Class 107.] A manhole frame is provided with an inner wall 3 and a somewhat higher concentric outer wall 4 so as to form an annular channel 5 which is provided with a plurality of radial webs or projections 7 and is normally filled with sand, the arrangement being that a depending flange 9 on the cover 8 is adapted to seat either on the sand filling or on the webs or projections. Alternate webs may be slightly higher than the other webs. The cover is strengthened by four radial ribs 10 on its undersurface, and notches 11 are provided in the upper edge of the inner wall 3 to accommodate such ribs. The outer wall 4 of the frame is strengthened by external ribs 6.

摘要： 288,060. Lobnitz & Co., Ltd., (Robinson, A. W.). June 20, 1927. Ball - and socket joints; couplings, disconnectible. - In a suction dredger having a discharge pipe comprising an outboard portion 9 on the dredger and a floatable portion formed in sections 34, 58, &c., with ball-andsocket joints for attaching the floatable portion to the outboard portion and for connecting the sections of the floatable portion together, the end of the outboard portion is provided with a ring 20 adapted normally to engage a boss 32 on the floatable portion and to be disengaged therefrom simply by pulling a lanyard 25 which acts on the ring 20 through a toggle device. The ball- and-socket joints are each provided with selfsealing rubber packing rings 72 held in a recess 71 in the socket member by an internal split ring 73, while the joints, other than the quick-release one, are provided with a known cushioning device 68. The outer end of the outboard pipe section 9 is preferably supported by a light tackle 74 connected to a hook 75 pivoted thereon, while a light tackle may also be provided on the floatable portion so that when it is released from the outboard portion it is still held attached to the dredger.

摘要： 230,622. Lobnitz & Co., Ltd., (Robinson, A. W.). March 6, 1924. Grab machines.-In grab excavators, dredges, and the like having a beam or jib in the form of a cantilever which is rocked by means of a pressure fluid cylinder acting thereon and which carries the grab by an inflexible member whereby the open grab is positively forced by the cantilever into the ground, the cantilever 21 has an arcuate portion 24 which rolls, as the cantilever is rocked, upon a track 10 carried by a turntable 3 mounted on the dredger &c. 1. The cantilever has its centre of gravity so situated that the cantilever is in stable equilibrium when in mid-position, so that, when it has been rocked to depress the grab, it tends to return to midposition. The pressure fluid cylinder 33 has its piston-rod 34 connected to the cantilever at the centre of curvature of the arcuate portion, which has flanged rolling surfaces 50, Fig. 2 , which roll upon a track with smooth side treads, between which is a rack 25a engaging with teeth 25 carried between the rolling surfaces 50 by the arcuate portion of the cantilever. The grab 108, which is of the kind described in Specification 229,110, [Class 78 (iv), Loading &c.], is closed, when desired, by a pressure fluid cylinder 121, or other closing means, acting upon a closing rope 113.

摘要： 192,261. Lobnitz, Sir F., (Robinson, A. W.). Dec. 29, 1921. Scoop-arm machines.-An excavating-machine comprises a turntable 11 carrying winches 6, 7 acting through ropes 21, 20 respectively to operate a scoop arm 18 carried by a boom 9 on the turntable, stabilizing spuds 26 operating in inclined or vertical positions, and a winch 8 acting through ropes 12 to rotate the turntable and through ropes 29, 30 to adjust the spuds; all these parts are supported on a platform 4 which is mounted on bogies 35, Fig. 1, when beginning an excavation, the latter being then flooded and the platform 4 secured on a float 45, Fig. 3, for the completion of the work. Some or all of the bogies 35 are driven from the winch 8 through helical and chain gearing.

摘要： 143,646. Lobnitz & Co., (Robinson, A. W.). March 4, 1919. Scoop-arm machines.-In an excavator or dredger, the scoop. arm e is advanced and retracted by one or more wire ropes 13, 14 which pass round a roller 11 to a drum 15 driven through gearing by an engine 16 carried by the boom; the drum 15 is further controlled by a band brake. Duplex hoisting-ropes g pass over parallel pairs of pulleys h, k to the winding-drum. A backing- rope 17 passes through the boom pivot 30 over sheaf 18 and through a fair-lead 19. Specification 1113/12 is referred to.

摘要： 127,393. Stone & Co., J., and Wells, A. May 27, 1918. Fixed-abutment type; packing vanes; valves, distributing and cut-off. - In a liquid-meter comprising a vane c oscillating about a fixed abutment l, the main distributing valve o is oscillated on its seat by an auxiliary vane u, the osciilation of which is controlled by an auxiliary valve w oscillated intermittently by a member v secured to the shaft e of the main vane c. For this purpose, the member v engages a projection w depending from the valve w, white the hollow auxiliary vane u engages a stem t on a revoluble member s engaging a pin o on the main valve o. Packing-grooves c are formed at the sides and tip of the vane c.

摘要： 124,931. Buck, A. W. April 26, 1918. Envelopes, sheaths, and holders, plate and like; R÷ntgen-ray and like apparatus. - A container for films for X-ray photography, more particularly for use in photographing the teeth, is made of material such that it may be bent and will retain the form into which it is bent. As shown in section in Fig. 3, the container comprises a thin back-plate 10 of a ductile metal having its edges 12 bent over to enclose both a film 13 and a front plate 11. The front plate consists of celluloid which is rendered opaque or transparent to red rays only, or of paper or other material which is opaque to light rays but permits the passage of X-rays. The back 10 is preferably made of bismuth, lead, platinum, or other metal of high atomic weight, and is held closely against the film by tightly clinching down the edges 12. In a modification, Fig. 4, the container comprises a metal rim 14 which encloses a back 10 of ductile or pliable material and a front 11 of celluloid or paper. In further modifications, the back may consist of ductile or pliable material faced with a metal of high atomic weight, and the front may be clinched over the back. The container may have rounded corners and may enclose a plurality of films in superposed arrangement.

摘要： 24,219. Stone & Co., J., Jakeman, G. E., and Wells, A. Oct. 21. Inspection openings, closures for.-Relates to (a) keying the road material around the frame, and (b) ventilating the man-hole by angular adjustment of a circular cover. According to the invention (a) inclined straight or curved bars 3 connect the base-plate 1 and the wall 2 of the frame, and are preferably wedge-shaped in cross-section, with the wide end of the wedge presented outwards. The thickened rim 5 may be bevelled and serrated, and may be strengthened by webs 6 alternating with the bars 3, and (b) the wall 2 of the frame is curved outwards, as shown at 7, in certain places arranged symmetrically around the circle, and the depending flange 9 of the cover is sloped inwards and upwards, as shown at 12, at certain parts similarly arranged and adapted to cooperate with the concavities 7 to allow air to enter the man-hole through slots 11, as shown in Fig. 7. To check the ventilation, the cover is turned until the slopes 12 and the concavities 7 no longer co-operate, as shown in Fig. 8.
