Title: Improvements relating to liquid measuring and dispensing apparatus
IPC: G01F11/00
Filed: 1933-09-23
Abstract: 426,267. Valves. AVERY-HARDOLL, Ltd., and FRASER, J., Avery House, Clerkenwell Green, London. Sept. 23, 1933, No. 26265. [Class 135] [See also Group XVIII] In meter pumps for measuring and dispensing petrol or other liquids, the cutting off of the liquid is effected automatically by the closure of a valve in two stages in order to facilitate and measure accurately the final portion of a delivery. The flow of liquid takes place through an inlet 49<c>, past the valve 50 and away through an outlet 49b, the valve being controlled by a lever 51<b> coupled through a shaft 51<a> to a lever 51 connected through linkage 48, 33, 34 to a crank 35 mounted on a shaft 36 actuated by a handle 37. The shaft 36 also actuates a rod 39 controlling the switch for the pump motor (not shown). The amount of liquid to be delivered is predetermined by setting a pointer 27<a> to the required indication on a dial 55, this action setting a wheel 29 splined on a shaft 27 into an angular position which is accurately determined by an adjustable spring-pressed pawl engaging notches in the periphery of the wheel 29. A rod 31 parallel to the shaft 27 is pivoted to the valve-controlling lever 33 and is coupled at 43 to a rock shaft 44 carrying a pawl 46. The indicator 27<a> having been set, the handle 37 is actuated, thereby operating the rod 39 to start the motor pump and rocking the valve lever 33 about its connection to the link 48 thus causing the rod 31 to move axially, whereupon an offset peg 30 at the end of the rod 31 and parallel therewith, engages the wheel 29 and moves it into engagement with a wheel 26 which is driven through spiral gearing by a pinion 21 mounted on a shaft 4 driven by the spindle of the flow meter (not shown). On the actuation of the rod 39, a stop 40 thereon engages a lever 41 and disengages the pawl from the wheel 29 which accordingly rotates with the wheel 26. After the rod 31 has been arrested by the engagement of the peg 30 with the wheel 29, further movement of the handle 37 rocks the lever 33 about the end of the rod 31 and opens the valve 50 against the pressure of the spring 49<a> thus initiating delivery of liquid. During delivery the rotation of the wheel 29 brings a hole therein into alignment with the peg 30 whereupon the rod 31 slides rearwards under the action of the spring 49<a> which partially closes the valve 50, this movement causing a pistonvalve 52, fast on the valve spindle 50<a>, to move across the fluid outlet and allow flow only through an orifice 52<a> in the pistonvalve. The motion of the valve spindle is damped by a disc 53 lightly pressed by a spring 54 and mounted on a flattened portion of the valve spindle to allow restricted flow of liquid from one side to the other of the disc. The rearward movement of the rod 31 throws the pawl 46 into engagement with a cam 47 on a shaft 9 which is also driven by gearing 6, 8 from the spindle of the flow meter, and the cam then actuates the pawl to produce further movement of the rod 31, thus allowing the valve 50 to be completely closed.

Title: Improvements in or relating to honing devices
Inventor: DAKIN MARCUS REX
IPC: B24D15/06
Filed: 1962-07-10
Abstract: 939,382. Honing. F. PARRAMORE & SONS (1924) Ltd. Sept. 10, 1962 [July 10, 1962], No. 26393/62. Class 60. A honing device for a narrow, strip-like plane blade comprises a holder with a downwardly projecting support rearwardly of a front edge of the holder, a narrow and shallow transverse recess being formed in the underside of the holder and opening below that front edge, clamping means on the underside of the holder and protruding over the recess, and means for tightening the clamping means to grip the underside of a blade placed in the recess. A narrow strip blade 1 with a single bevelled edge 2 fits into a shallow recess 4 across the underside of the lower end 5 of a holder 6 with the plain square rear edge 3 of the blade bearing against a correspondingly plain square rear edge 7 of the recess. The width of the recess 4 is sufficiently less than that of the blade 1 for the bevelled edge 2 to project allowing the bevelled face to lie on the surface of a hone 8, the holder 6 being inclined at the correct angle by having a roller 9 carried by a support 10 projecting downwardly from its underside. The support 10 is a sheet-metal stirrup secured, together with one end of a clamping plate 11, by a screw 12 screwed into the holder 6. The lower end 13 of the plate 11 overlaps the recess 4 but remains clear of the hone when that end is drawn by a screwed pin 14 riveted to it into gripping contact with the underside of the blade 1. The pin 14 passes through a hole 15 in the holder 6 and carries a knurled nut 16 by which the plate is tightened. The plate 11 is narrower than the lower end 5 of the holder 6 and fits, over its upper portion, the sides of a channel 17 in the underside of the holder 6, the sides of the stirrup support also fitting the sides of the channel. The width of the holder 6 is reduced towards its upper end, so that the outer side surfaces 18 provide a convenient thickness for gripping by the user; the sides may be knurled or otherwise roughened and merge by rounded surfaces 19 into the rear of the wider lower end 5 of the holder. A single-edged blade 1A, Fig. 6, has one or more holes 20 receiving one or more pegs 21 pro. jecting from the underside of the lower end 5 of the holder 6. A double-edged blade 1B, Fig. 7, with both cutting edges at one face of the blade, has a lengthwise slot 22 fitting a transverse locating rib 23 in the lower end 5 of the holder 6. A transverse groove 24 in the holder 6 avoids contact with the cutting edge not being honed. A double-edged blade 1C, Fig. 8, with its cutting edges at opposite faces, has a lengthwise rib 25 fitting a transverse locating groove 26 in the lower end 5 of the holder 6. A transverse groove 27 in the plate end 13 avoids contact with the cutting edge not being honed.
