摘要： 398,983. Moulding concrete pipes in centrifugal machines. WILLIAMS, R., 19, Bligh Street, Sydney, Australia. July 18, 1932, No. 20297. [Class 87 (ii).] In centrifugal moulding-apparatus for manufacturing concrete pipes and the like of the kind in which the pipe mould is inserted into a tubular casing or carrier supported between rollers for rapid rotation, the rollers are adjustable radially to hold the carrier securely without lateral vibration during its rotation, thus enabling high speeds to be used. In the illustrated form a two-part pipe mould assembled by bolts 25 is placed in the rotary carrier 18, the bolts fitting into recesses 26 so as to form a positive driving connection between the mould and the carrier. The latter carries recessed hardened bearing rings 17 running loosely in U-shaped standards 3 and engaged and supported by eccentricallymounted rollers 15 running on ball or roller bearings. In operation the concrete is placed in the mould and the latter then placed in the carrier and rotated by means not shown. A brake shoe 37 applied by a hand-lever stops the rotation when desired. Packing-pieces 8, together with the eccentric mounting of the rollers 15, permit the rotary pipe to be held securely without rattling or lateral vibration. The pipe may also be centred accurately by independent adjustment of the rollers. The mould may have a socket-forming core at one end connected to the main portion by a bayonetjoint or by fly-nuts. The formed pipe may be trowelled by known means before removal from the machine. The standards may be arranged to form lubricating chambers round the rollers 15 which may be supplied through lubricating- devices 40.

摘要： 239,162. Williams, R. Aug. 26, 1924. [Convention date]. Centrifugal machines.-Moulds 26, Fig. 7, are fixed on the inside of a rotatable polygonal drum 5, Fig. 4. A feed cylinder 9 passes into the drum and rests at one end on anti-friction rollers 13. The moulds are secured by T-bars 28. On the feed side a the drum is fitted with hinged doors, one for each mould. The cylinder 9 is formed with feed openings, preferably helical in form. A feed tube and worm may be inserted in the cylinder 9. The apparatus is primarily intended for making concrete slabs.

摘要： 531,032. Metal pipes. WILLIAMS, R. July 10, 1939, No. 20051. [Class 99 (ii)] [Also in Group XXII] A metal pipe consists of a single continuous helically coiled flat metal strip with rectangularly projecting equal-sized flanges on its edges welded together by a joint the area of which is not less than the contacting areas of adjacent flanges. In making externally ribbed pipes welding may be effected by electric resistance and in the case of internally ribbed pipes by electric arc or torch along the groove in the outer side of the pipe as shown in Fig. 2a.

摘要： 290,050. Williams, R. May 30, 1927. Cenfrifugal machines.-A rotatable frame 5 carries a plurality of removable trays or moulds 17 arranged in tiers one above the other, and clamped securely by a plate 22 which serves as a cover for the uppermost tray, and which is raised or lowered by means of a handle 31 on a transverse shaft 29 through bevel gearing. The trays filled with plastic material are slid into position from a trolley 18 and are withdrawn on to rails 21 when the moulding operation is completed. If only one end of the frame is used for receiving trays, balance weights are employed at the opposite end. The frame 5 is rotated from a driving shaft 33a by means of a band 10 and pulleys 10, 43 through a friction clutch 42, and screws 38 are provided for adjusting the position of the supporting frame 36. Additional braking means comprises a brake wheel 11 and pivoted closing members 45, 46 which are brought into engagement therewith against the action of a spring 48 by means of a lever 51.

摘要： 396,931. Moulding slabs &c. in centrifugal machines. WILLIAMS, R., 19, Bligh Street, Sydney, Australia. July 18, 1932, No. 20298. [Class 87 (ii).] Apparatus of the kind described in Specification 290,050, [Class 87 (ii), Moulding plastic &c. substances], for the centrifugal moulding of blocks, slabs, and like constructional elements, is modified so that the rotating frame receives both the moulds and their carrying trolleys which are run in from a lateral track and run out again at the completion of the operation. Means for locking the moulds on the trolleys and the trolleys in the frame also are provided. In the construction shown in Fig. 2, tiers of charged .moulds, clamped by screwed bars 33 on to wheeled platforms 10, are run into a railed compartment in the framing 6 and are clamped therein by the screws 34. The shaft 4 is then rotated by power applied to the belt pulleys 14 until the diametrically-opposite cage on the framing comes into position for loading. When the frame is fully loaded the shaft 4 is rotated to compact the material in the moulds. A hand brake 19, with spring-actuated brake blocks and a screw setting-mechanism, is fitted to the shaft. In a modified construction three or more moulds may be symmetrically arranged about the axis 4 or a single mould may be balanced by a diametrically-opposed adjustable counterweight. In the latter case the loaded platforms are weighed before passing on to the apparatus and the counterweight correspondingly adjusted on a fixed scale on the machine. The moulds used may comprise a rabbeted baseplate 43, preferably faced with metal 48, surrounded by two L-shaped members 45 of angle-iron section. These two members are pivoted at one corner and latched or bolted together at the opposite corner. In some instances a clamped-on top plate is added which may be utilized to support a core.

摘要： 239,163. Williams, R. Aug. 26, 1924, [Convention date]. Centrifugal machines for moulding pipes &c. are fitted with anti-friction bearings having an outer annular stationary race-member to allow of high speeds without vibration, and comprise a casing 5 and a mould 6 supported at intervals by bearings 7. The moulds may be supported by means of stub axles 8, Fig. 7, through which the mould may be fed; or one end may be detachable, being mounted for this purpose on screwed spindles, the mould meanwhile being supported on a jack 44. The moulds may be held in the bearings by sliding tapered annular collars. In the case of moulds for long articles. a cage, Fig. 9, comprising rings 48 joined by bars 47 is inserted in the easing to carry the mould. According to the Specification as open to inspection under Sect. 91 (3) (a), the anti-friction bearings are not necessarily contained in a stationary race member, and a number of moulds may be adjustably mounted in vertical frames- This subject-matter does not appear in the Specification as accepted.
