Title: Improved vehicle-washing apparatus
Inventor: WEBBER JOHN STANLEY
IPC: G07F17/20
Filed: 1963-05-24
Abstract: 1,089,794. Coin-freed washing facilities. J. S. WEBBER Ltd. Aug. 21, 1964 [May 24, 1963], No. 20787/63. Heading G4V. Vehicle washing apparatus comprises a manually operable coin-freed priming device for starting a timer and actuating a switch which returns to its original interval after a pre-set interval, and a hose connected to the outlet of a water valve operable by means in circuit with the switch. Figs. 2-4 are three sectional views of the coin-freed and timing mechanism, comprising a disc 14, manually rotatable by a knob (not shown), and normally prevented from significant rotation by engagement of a catch 19 with a recess in the disc. When a coin of the correct size falls into slot 25, however, the catch can ride up the coin and clear the recess. A finger 27 on the disc 14 normally abuts a lever 28 on shaft 29 of a timing spring (not shown), so that rotation of disc 14 winds the spring until an arm 23 rotating with the disc abuts stop 30. Pawl and ratchet mechanism 32, 31 ensures that disc 14, when rotated, must be rotated the full amount, and in direction A only, until winding is complete. The switch controlling the water valve (not shown) is actuated with arm 28, so as to be closed while the arm is not in its datum position. When the device is first wound, the water valve is held closed by opening of switch 18 until the winding up is complete and arm 23 is returned by spring 24 on release of the manual winding knob. The valve is then open, while arm 28 is returned to its datum position by the timing mechanism. This pre-set interval may be varied by insertion of finger 27 in various holes 44, 45, and by adjustment of a screw 46 on arm 28 extending towards finger 27. The hose may terminate in a brush containing solid detergent, or an auxiliary valve, directly operated by the customer, may add detergent to the water flow as required. The switch operated by the timer may also control an indicator lamp.

Filed: 1947-08-01
Abstract: 636,915. Knitting. HEMPHILL CO. Aug. 1, 1947, No. 20994. Convention date, June 14, 1939. [Class 74 (ii)] The selvage of a knitted fabric incorporating elastic thread, particularly the edge of a knitted stocking top, is formed by feeding an elastic yarn for a number of courses to every alternate needle without knitting the elastic yarn, feeding an inelastic yarn to all of the needles and drawing it so that the elastic yarns are cast off the alternate needles and then continuing to knit courses incorporating either or both of the elastic or inelastic yarns. In taking the number of elastic yarns fed at the initial stage by only alternate needles and then knitting an inelastic yarn by all of the needles, the elastic yarns are caused to pass through all of the sinker loops of this following inelastic yarn. Following the formation of the initial courses, the fabric may be knitted to incorporate elastic yarn as described in Specification 528,673. Alternatively, following the initial courses a course of elastic yarn may be incorporated in the fabric so that it is tucked along with stitches of the inelastic yarn.

Abstract: 344,325. Engraving. KOLSTER-BRANDES, Ltd., Cray Works, Sidcup, Kent.-(Assignees of Brower, W. M. ; Palo Alto, California, U.S.A.) July 11, 1930, No. 21114. Convention date, July 11, 1929. [Class 100 (ii).] A compass scale for a radio-gonion.eter is engraved in such a way as to n.ake provision for quadrantal or similar cyclic error. The scale blank is mounted between two uniformly divided scales, and a flexible cam, which has previously been deformed to simulate the existing error, is utilized to control the sense and extent of relative movement between the two uniformly divided scales, whereby the blank is engraved with non-uniform divisions which enable a corrected reading to be taken at sight. One standard scale is marked on the face of a gear-ring 3, Fig. 2, the scale being viewed through a window 7, Fig. 1. The second scale is marked on the bevelled edge 22 of a plate 21 mounted on a shaft 20. The gear-ring 3 rotates in ball bearings 18, 19 and drives the plate 21 through a flexible connection comprising a shaft 30, a arm 37, Fig. 2, cable 39, Fig. 1, pulley 40, and a arm 43 mounted on the shaft 20 and tensioned by a spring 45. The extent and degree of deviation between the movements of the two scales, as they rotate, is determined by a flexible cam plate 33 bearing against a roller 32 mounted on a crank arm 3 at the lower end of the shaft 30. A preliminary test is made on board the ship &c. for which the compass card is intended, in order to ascertain the quadrantal error curve, and the cam plate 33 is deformed by means.of screws 34 to simulate this curve. A blank scale for calibration is then screwed on to the plate 21 on which one standard scale is marked, and the handle 9 is rotated until the zero point on the gear-ring scale 3 is opposite the sight wire 8. The new scale is then calibrated by an engraving tool 57 mounted on a bar 55 carried by an operating lever 54. The scales are rotated step by step by means of a handle 9 and worm 4 gearing with the ring 3. Pressure is applied to the graving tool at each stroke of the lever 54 by a resilient plunger 60 which moves out of a recess 62 on to the surface of the bar 55. An adjustable stop may be provided to limit the stroke of the operating lever 54 in order to vary the length of the line engraved at intervals of 5 or 10.
