Abstract: 1,014,400. Micrometer gauges. O. WIEGEL. May 4, 1964 [May 14,1963], No.18344/64. Heading G1M. A micrometer operable reference height gauge comprises a pillar 14, a slide 24 mounted for vertical movement on the pillar and having a plurality of units 54 extending therefrom, the units 54 each having a pair of tongues 62, 64, the tongues 62, 64 of each of the units being arranged as a pair of columns, one of the columns having equally spaced top reference surfaces 56 and those of the other column having equally spaced bottom reference surfaces 58, the reference surfaces of said one column being horizontally aligned with the reference surfaces of said other column in pairs, the tongues being substantially thinner than onehalf the vertical distance between reference surfaces. As shown in Figs. 1 and 2 the slide 24 is slidably mounted in groove 22 in the support 10, its weight being counter balanced by compression springs 48. The tongues 62, 64 as shown in Fig. 3 are carried by units 54 which are stacked in grooves 50 and retained in position between plates 70 and 84. A micrometer assembly 98, of conventional type is attached by means 92, 94, 96 to the support 10. In an alternative arrangement see Fig. 5, bars 130 replace the units 54 and are provided with tongues 134, one bar being reversed with respect to the other when they are placed in the columns 50 to provide the top and bottom faces. In use, to establish a reference height the appropriate tongue is selected and the micrometer then moved to carry the slide no more than half the distance between successive tongues.

Abstract: 130,976. Sansa, R. Aug. 5, 1918, [Convention date]. Void [Pablished under Sect. 91 of the Act]. Spray carburettors.-To prevent an excessive flow of fuel at high speeds, the space above the fuel in the float chamber 1 is in communication through a duct 27 with the mixing chamber 24 containing a throttle valve 26. The depression above the fuel may be regulated by varying the effective bore of the conduit 27, or by varying, by means of a screwed plug, the area of holes which place the top of the float chamber in communication with the atmosphere. To facilitate starting and slow running, a by-pass nozzle 15 delivers into a passage 17 which communicates at one end with the atmosphere through an adjustable orifice 18 and, at the other end, with the induction pipe near the edge of the throttle valve in its closed position. The main nozzle, of comparatively large diameter, has a restricted orifice at its base.

Title: An improved one way motor plough
IPC: A01B3/56
Filed: 1922-07-11
Abstract: 205,179. Champion, F. July 11, 1922. Balance ploughs; lifting parts of; steering - gear; motors; arrangement and control of.- In three - wheeled one - way motor ploughs of the kind described in Specification 130,759, the ploughs are supported in such a way that the point of application of the draught is adjusted automatically, and means are provided for operating the steering- wheels, for adjusting the width of furrow, and for raising and lowering the ploughs and pressing them into the ground in succession through the operation of a band clutch. The implement is provided with a main driving-wheel A and with two steering-wheels E<1>, E<2> in line with one another. The wheel A is driven from an engine F through change-speed and reversing- gearing in a box H. The axles 7A, 7B of the wheels E<1>, E<2> turn about the axes of vertical parts 6 and are fitted with small flanged wheels 8 engaging arc-shaped pieces W. Steering is effected bv turning a spindle on which is a bevel pinion 13 engaging with two quadrants which are connected to the axles 7A, 7B by rods 10, 11 and universal joints 9A, 9B. The two sets of ploughs are connected to draught levers 15, 16, 17 mounted on two cross-bars 14, the levers being slotted to allow the connecting-pins G to adjust themselves automatically. Cams 19, 20, 21 on a shaft 18 lift the ploughs in succession by pressing upon the levers 15, 16, 17 that carry pulleys 28 around which pass cords 31 fastened to the frame at one end and to the ploughs at the other. At the highest point projections 29 are engaged by pivoted hooks 23 which automatically swing into position. Pivoted levers 25 having ends which engage the plough beams 22 are connected to the levers 15, 16, 17 bv links 27 so as to exert pressure on the ploughs when the levers 15, 16, 17 are drawn backwards. The hooks 23 holding up the first plough may be moved by means of a cam 53 connected by a rod 52 to a lever 50. As each plough falls its pressure lever 25 actuates adjustable mechanism for releasing the next plough. The distance between the ploughs is adjusted by turning the cross-bar 14 which is screw-threaded to engage with sleeves on which the levers 16, 17 are pivoted, the threads being arranged to move the lever 17 twice as far as the lever 16. The lifting-cams &c. move laterally with the levers 16, 17. The lifting-shaft 18 is turned by a rod 44 connected to a crankpiece 34 which may be clutched to a drum 49 on the axle of the main w'heel A by means of a band clutch 35. The band is fastened to two connected levers 37, 40 pivoted on pins 38 on the crank-piece 34. The clutch is operated by means of cams 36, 39 connected by rods 42, 43 to a lever 41 actuated by a hand-lever. When one of the cams is brought into engagement with one of the curved levers 37, 40, the band is tightened on the drum 49 and the pressure on the ploughs is released and the ploughs raised successively. The band is loosened when the end of the locking-lever 37, 40 passes the cam 39, 36.
