Title: Improved weighing machine with recording gear
IPC: G01G3/04
Filed: 1919-08-08
Abstract: 146,556. Hill, F. A. Aug. 8, 1919. Platform machines; relieving- mechanism; spring balances.-Relates to the construction and arrangement of parts in that kind of platform or equivalent spring weighing-machine wherein each load is indicated on a dial, the successive loads are totalled and the number of times the machine has been operated is indicated. The load pulls down a plate E, Fig. 1, connected to weighing springs 1 - - 6, and the movement is transmitted by a link F, toothed sector D and pinion to an indicating spindle carrying a pointer G. Secured to the indicating spindle is a lever B with teeth B<1> which rotate in usual manner a graduated wheel C mounted on ball bearings, the graduations in this case showing two maunds subdivided into seers. When the load is removed from the machine, the wheel C is prevented from returning to the zero position by a spring which engages ratchet teeth on the wheel. During the rotation of the wheel, strikers L, M arranged at the zero graduations operate a counter 15 to register the total number of maunds placed on the machine. The platform Q is connected to the weighing-springs by a draw-bar P which may be raised or lowered by a hooked rod S operated by a relieving-lever R. Each time the relieving- lever is actuated to place the machine in operation, a rod H attached to the relieving-lever operates a counter 26. The extent of movement of the indicating-spindle may be adjusted by adjustment of a screw connexion between the link F and the toothed sector D.

Abstract: 524,962. Casting-machines; moulds. EBONESTOS INDUSTRIES, Ltd., and AMIGO, A. Feb. 11, 1939, No. 4572. [Class 83 (i)] [Also in Group V] An injection moulding- apparatus for synthetic materials is stated to be suitable for casting metals, and it comprises an inner member 14, mounted on a base 13, and a number of side members 11 adapted to be slid upon the base to and from the inner member and forming with it a number of separate mould meeting faces comprising ducts 19 and mould cavities 15, 16. By being higher than the inner member the side members also form a pressure chamber above the inner member with that member as the bottom thereof. The inner member has an exchangeable top portion 17 and those portions of the side members which form the walls of the pressure chamber are provided with removable mountings 18. The compression plunger 2 is carried by a plate 1 fitted with pistons 3, 20 working in the pressure cylinders 5 of a conical ring 4 having a rectangular central opening. Parts 8 adapted to form the end members of the pressure chambers are slidably mounted in the end faces of the opening, the movement of each part being limited by the engagement of a slot 9 with a pin 10 on the guide 7 of the part. The inner member may be hexagonal and divided into six parts with further mould cavities on the meeting faces of the parts. Or the inner member may be cylindrical and comprise a central core, of the same height as the outer members, and intermediate ring segments of less height, the compression plunger being annular. Or the core and intermediate members may be elongated to co-operate with corresponding outside members and parallel compression plungers. After the mould has been closed, metal is introduced into the pressure chamber from which it is forced by the plungers through the ducts into the moulds. When the mould is opened all the waste metal comes away with the castings.

Abstract: 212,538. Eckardt, C., and Bost, H. March 8, 1923, [Convention date]. Transfer mechanism for cam-disc and pinwheel calculating-machines. The two transfer pins in each pin-wheel are individually moved outwardly by the relative rotation of a special cam disc. A stationary shaft 1 is surrounded by a rotatable sleeve 2 carrying the pin-wheels 3, ordinary cam discs 4 for the differential actuating pins 28, and auxiliary cam-discs 5. The two transfer pins 14, 14a at each end of the actuating- pins 28 are operated by their lateral projections 30, 30a moving in slots 10, 11 in the auxiliary cam-disc 5, which also has a slot 8 co-operating with a projection 7 on a pin 6 moving in a groove 31 in the pin-wheel. The cam-disc 5 has further nine teeth 13 adapted to co-operate with a spring- pressed pawl 12 caused at transfer, by a pin 32 on the numeral wheel b, to wipe past the pawl, momentarily forcing it into one of the ten gaps 13<a> between the teeth 13 so as momentarily to arrest the disc 5, this relative rotation between the disc 5 and the pin-wheel 3 causing the projection 30 or 30<a> to ride up the slot 10 or 11 and project the transfer pin 14 or 14<a> which then actuates the adjacent numeral wheel. At the same time the projection 7 rides towards one of the ends of the slot 8. After transfer the return relative rotation of the cam-disc 5 is effected by a cam 9 on the stationary shaft 1 engaging the pin 6 and causing the projection 7 to move in the slot 8 so as to rotate the disc 5 slightly.
