Title: Improvements in or relating to presses for producing tubes particularly of cement
IPC: B28B21/26
Filed: 1932-03-10
Abstract: 378,816. Moulding concrete &c. pipes. GRABER & WENING, Neftenbach, Switzerland. March 10, 1932, No. 7218. Convention date, Feb. 1, [Class 87 (ii).] In apparatus for making cement tubes in which the core comprises a rotating piston fitted with projecting helical ribs which exert pressure on the cement and thus raise the core progressively in the mould as more material is fed in, the motor for rotating the core is mounted on the movable framework and moves up and down with the core. In the illustrated form the pipe A is formed in the mould 17 by the series of ribs 33 on the rotating core or piston 11. The piston rod 10 is journalled in a sliding frame 2 carrying the motor 5 and a worm transmission-gear 6, the lowest bearing being encased as at 14 to protect it from the falling concrete. The frame is counterbalanced partly by four chains 18, 19, Fig. 3, connected to a weight 24 and partly by weights 28 carried by ropes secured to pulleys 25. Rotation of the shaft 22 through the medium of the handle 32 and chain gear 29, operates the ropes and chains to raise or lower the frame and piston at will. The tapered ring 37, forming the lower end of the mould, is carried by a wheeled table running on channel rails 39 and fitted with racks 40 so that it can be run laterally out of the machine to deliver the moulded pipe by operating the hand-wheel 44 connected to the pinions 41 by a chain drive. A ring or table 45, which receives the surplus moulding material displaced by the upward movement of the piston, is provided with four toothed wheels 52 engaging corresponding racks on the framing and all operated simultaneously by worm gear rotated by the hand-wheel 46. In operation the empty mould is run into the machine by operating the handle 44, and the piston lowered to the bottom of the mould by operating the handwheel 32. The plate 45 then is lowered on to the top of the mould by operating the hand-wheel 46. The motor 5 then is started. At the conclusion of the operation the piston is raised still more by operating the hand-wheel 32 until it is freed from the mould, and the plate 45 then raised before the mould is run out of the machine again. The piston is fitted with renewable wearing rings 35, 36.

Abstract: 438,317. Paddle-wheels. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M. [Firm of]), Heidenheim-on- Brenz, Wurtemberg, Germany. March 14, 1935, No. 7966. Convention date, March 26, 1934. [Class 4] Means for feathering the blades of a blade wheel in which the blade axes are parallel or approximately parallel to the wheel axis, comprise an eccentrically movable member C, Fig. 1, which is centrally located when the pitch of the blades is zero and which revolves with the blade wheel, and rods G pivotally connected thereto at F and adapted to slide longitudinally through oscillatable guides H the pivotal points of which are fixedly located upon wheel A and from which the angular movement of blades B is obtained. The control member C is rotatably mounted on a ball pivot D, Fig. 2, supported in a stationary bearing E and movable by hand or by external control means to impart any desired degree of eccentricity to member C. Member C is driven with wheel A by means of a coupling lever K formed at its outer end with a guide slot k<1>. In a modified form, one slide rod G<2> is rigidly, instead of pivotally, connected to member C, thus by virtue of the fixed location of its associated guide block H serving to rotate the control member. In order to compensate for the difference in the angular velocity of control member C and of wheel A the lengths of rods J connecting slide rods G with blade levers b<2> are made slightly different one from the other and slide blocks H are not located upon a circle about the axis of the wheel body. Fig. 4 shows diagrammatically the relationship between the angular positions of the rod G and of the blade arm b<2>. It will be seen that owing to the periodic variation in the free length l of rod G, the velocity of joint g<1> is particularly high during the period in which the blade pitch changes from a positive maximum to a negative minimum value. The optimum result is stated to be obtained when the gear is so arranged that with the control member central the guide member intersects rod G at a point between one-half and one-third of its length from the inner end. The blade wheel may be employed for propelling ships or aircraft or as a rotor in hydraulic or wind power machinery.
