Abstract: 254,465. Hough, T., and Tickle & Co., Ltd., J. May 14, 1925. Testing hardness of materials-Comprises an indenting tool, resilient means for transmitting pressure to the tool from an operating member, means for indicating when the specimen has been penetrated to a predetermined depth and means for indicating the relative movement between the tool and the operating member. A bracket o vertically adjustable on a pillar n supported on a base m carries a pillar q to the upper end of which is pivoted an operating lever r. This lever can transmit motion through a part s to upper and lower cross-heads c connected together by rods p mounted in the bracket o. A spring t located between a collar on the part s and an abutment u carried on the pillar q returns the lever r to normal position. To the lower end of the pillar q is secured a guide v for the holder c on which is formed or secured the diamondpointed tool b. A resilient transverse bar d connects the holder c to the lower cross-head e. Relative movement between the cross-head and the holder is indicated by a dial gauge g carried on the cross-head with the movable part in engagement with the upper end of the holder. A feeler h engages the specimen as near as possible to the point of the tool b and is adapted to move a lever i carrying a contact co-operating with an adjustable contact carried on a plate j fixed to the holder. The contacts are connected in circuit with a battery and a flash lamp k illuminating the gauge g. In use, the tool b is pressed into the specimen by operating the lever r the lighting of the lamp signalling when the specimen has been penetrated to the correct depth. The pressure may be read off or deduced from the reading of the gauge. In a modification, the holder ends at the upper end in a piston on each side of which is a spring between the piston and a cylindrical casing taking the place of the crossheads e. In this form a mercury contact is employed for the flash lamp instead of the lever i.

Abstract: 406,154. Prepayment mechanism for meters. McROBBIE, W., 14, Orchard Bank, and MILNE'S METERS, Ltd., 22, Milton Street, both in Edinburgh. Dec. 3, 1932, Nos. 12509/33 (divided on 404,980) and 13114/33. [Class 27.] Coin action, thrust and multiple-coin.-In prepayment mechanism for meters operable by coins of different denominations to advance quantity-mechanism an amount proportional to the value of the coin, the coin-actuated mechanism selectively engaging a plurality of driving teeth with a plurality of appropriate driving gear wheels, a coin, such as a penny or a shilling, is inserted through a slot in a pricechange disc to a pocket 3 on a plate Y, Fig. 2, rotatable by an outside handle. The coin depresses the arm 10 of a lever 10, 14 pivoted at 11 to the plate Y against the action of a spring in a housing 13, a lug 12 on the bell-crank lever bearing against the spring. The arm 14 has a pin or roller 15 engaging a cam slot 16 in a plate 17 pivoted to the plate Y and provided with a toothed dog 19 in alignment with the pivotal axis. The dog 19 has a pair of teeth 19a, 19b of different lengths to engage with one or with both of two measuring-wheels as described in Specification 404,980 according as a penny or a shilling is inserted. A shilling depresses the arm 14 so far that the dog is rocked in one direction for the tooth 19a to engage both measuring-wheels while a penny depresses it to its full extent and rocks the dog in the opposite direction to engage the tooth 19b with one of the wheels. If a coin of any other size is used, the dog is rocked so that neither tooth engages the wheels. In a modification, Figs. 4 and 5, the coins rock a spring-controlled plate 10 about a pivot 11, this plate having a pin or roller 15 engaging cam slots 16a, 16b in two plates 17a, 17b which are pivoted at 18 to the coin pocket 3 and have one and two teeth x<3> and x<1>, x<2> respectively. When a shilling is inserted, the pin 15 rocks the plate 17a only and travels idly in a circular portion of the slot 10b. This causes the teeth x<1>, x<2> to engage both measuring-wheels which are thus locked for rotation together. On insertion of a penny, the pin 15 moves to the portion y of the slot 16b thereby rocking the plate 17b only since it now travels in a circular portion w of the slot 16a. The tooth x<3> now engages and drives one of the measuring-wheels only. If it is desired to use shillings only, a pin is inserted in holes 26 below a lug 27 on the plate 10. When pennies only are to be used, the pin is inserted in the holes above the lug 27. Specifications 275,510, [Class 27, Coin-freed apparatus &c.], and 376,773 also are referred to.
