Title: Improvements in or relating to apparatus for measuring the area and/or volume of elongated objects
Inventor: KINGSLEY PAUL ROBERT
Filed: 1958-11-17
Abstract: 913,241. Area meters; counting-apparatus. ENGLISH NUMBERING MACHINES Ltd. Oct. 8, 1959 [Nov. 17, 1958], No. 36892/58. Class 106 (1). . Apparatus for measuring the surface area of planks of wood or the like comprises a specially formed tapered roller rotated by engagement with one edge of the plank as the latter is passed lengthwise through the apparatus and driving a counter, the driving ratio between the plank and the counter depending on the point of engagement with the roller and consequently on the width of the plank, the other edge moving against a fixed guide on a similar roller. In the latter case, the two rollers 12 are inclined as shown and drive, through an averaging differential gear 17, a counter 26 which indicates the area. The drive is preferably taken also through a gear-box 23 which may be set by a knob 24 to one of a number of different gear ratios corresponding to different thicknesses of plank so that the counter may indicate the volume of the plank. The gear-box 23, Fig. 5, has an input shaft 52 carrying gears 53b, 53c ... of varying diameter which mesh with corresponding gears 54e, 54f, 54g . . . on a shaft 55. The gears 54e &c. constantly mesh with gears 57 individually mounted on levers 56, each of which is rockable so as to engage its gear 57 with one of a series of gears 58 on an output shaft 61. The ends 64 of the levers 56 normally bear on a cylinder 65 but this has holes 66 and is settable by the knob 24 to allow the end 64 of a selected lever to enter the corresponding hole 66 and so to allow a spring 62 to engage that gear 57 with its gear 58. The corresponding pair of gears 53, 54 is thus rendered effective to determine the gear ratio between the input and output shafts.

[Class 103 (iv).] In a railway freight wagon of the kind having a number of removable goods containers and in which buffing devices are mounted between the ends of the wagon and the containers for absorbing longitudinal shocks during transport, each buffer 19 is carried by a shaft 7 that is slidable between spaced bracket supports 4, 5 against the action of one or more encircling springs 23, 24. Preferably, as shown, the shaft 7 comprises parts 8, 9 of square cross section guided within corresponding apertures in the brackets 4, 5 and an intermediate cylindrical portion 10 of larger diameter on which is rotatably but non-slidably mounted a carrier 11 in which the buffer 19 is capable of a screw adjustment. Sliding movement of the carrier 11 is prevented by sleeves 13, 14 fixed on the cylinder 10, while the sleeve 13 has a shoulder 15 against which a shoulder 17 on an extension 16 of the carrier 11 abuts to limit the movement of the latter as it is rotated to its erected or operative position. A key pin 27 passed into aligned holes 25, 26 on the parts 11, 10 locks the buffer in this position. Prior to moving the containers on to or off the longitudinal tracks of the wagon at one end, the pins 27 must be removed and the buffers swung down into a well 3 in the wagon floor. In the arrangement shown a light spring 23 and a stronger spring 24 are employed for absorbing the shocks and bear at their inner ends against an adjustable nut 22 threaded on an extension 20 of the shaft 7. Specification 275,982, [Class 103 (iv), Railway &c. vehicles, Body details &c. of], is referred to.
