Patent GB-115252-A (GB)
IPC: G07F5/08
Abstract: 115,252. Lewis, R. G., Brooker, H., and Whiteley, A. March 28, 1917. Delivery of articles from piles.-The apparatus is adapted to deliver an article from one of several piles of goods of the same or of different value, or from a single pile. Fig. 1 shows an arrangement, described also in Specification 115,399, for delivering from piles a of goods of different values. A selector bar d, mounted in a spring-controlled carriage i reciprocating on guide-rods i, is moved laterally (by the operation of a spring-controlled pull-bar h, Fig. 3) in a direction at right-angles to the direction of movement of the carriage, so as to bring a projection k into position opposite the operating lever c of the delivery slide of the required pile, the selector bar and carriage then moving forward with the pull-bar to effect the delivery of the article. The selector bar is provided with a rack d<1> and is moved laterally by a pinion c, which is secured to a second pinion e<1> operated by a rack f on the pull-bar, until the stepped end of the selector bar engages a coincontrolled stop l. The extent of the lateral movement of the selector bar is dependent on the vertical position of the stop bar l, which is determined by the value of the coin or coins inserted. Springs v, which oppose the forward movement of the carriage are stronger than the springs w opposing the forward movement of the pull-bar. Coin action, multiple.-The stop l is adapted to be lifted, to an extent proportional to the value of the coin or coins inserted, by means of driving- pawls n, which are mounted on coin-actuated levers m and co-operate with a rack on the stop, a detent o serving to maintain the stop in the raised position; thus a halfpenny serves to raise the stop through the space of one tooth, and a penny two teeth. Separate pawls are provided for each value of coin, the different coins being directed to their respective pawls by a coin-sorter p. During the outward movement of the carriage i, the pawl o is tripped by a fixed stop 2, whereupon the stop l drops to its lowest position.

Title: Improvements in and relating to oil burning installations for furnaces
Inventor: HOBSON ERIC DOTT
IPC: F23D11/28
Filed: 1954-04-22
Abstract: 753,910. Supplying liquid fuel to burners. YARROW & CO., Ltd. April 13, 1955 [April 22, 1954], No. 11720/54. Class 75(1). An oil supply system for spill burners 15 comprises a low pressure pump 1 delivering oil to heaters 6, a high pressure pump 13 delivering oil from the heaters to the burners and means for delivering the spilled oil from the burners into the oil line between the heaters and the low pressure pump 1. The spilled oil passes along a pipe 17 into a chamber 5 through which cold oil from the low pressure pump 1 passes to the heaters 6, the spilled oil being directed tangentially to the flow of cold oil by nozzles 19. The oil pressure at the inlet side of the high pressure pump is maintained constant by an arrangement comprising a by-pass pipe 20 connecting the inlet and discharge sides of the low pressure pump 1 and a diaphragm valve 21 which opens the by-pass when the pressure at the inlet side of the high pressure pump 13 exceeds a certain value. The inlet and discharge sides of each pump are connected through a pressure relief valve 25, An oil filter 12a is disposed between the heaters 6 and the high pressure pump 13.

Title: Improvements in razor
IPC: B26B21/32
Filed: 1933-04-21
Abstract: 401,190. Safety razors. PATENTS, Inc., 100, West 10th Street, Wilmington, Delaware, U.S.A. April 21, 1933, No. 11735. Convention date, April 28, 1932. [Class 30.] A safety razor having a transversely-flexed, clamped blade 37 has the clamping-plate 24 pivoted at one end 21 and moved quickly from a fully open position, Fig. 4, to a blade-clamping position, Fig. 1, by rotation of a handle-member such as an end-knob 14, which, on continued rotation serves to apply pressure slowly to the blade through the usual screw-means. In the form shown in Figs. 1, 4 and 5 a base-plate 15 is fixed to the upper end of a tubular handle 11 and the blade is clamped against the clamping plate 24 by abutment of the flanged end of an internal handle-rod 12 against the underside of a loose, removable guard 32. To release the blade, the rod 12 is unscrewed, by turning the end-knob 14, until its screw-socketed upper end is free from a central screw 28 on the clamping- plate. Continued unscrewing of the rod, in a lower handle-thread 13 of the same pitch as the clamping-screw 28, retracts the rod sufficiently for the engagement of incomplete teeth 36, Fig. 5, on its upper end with rack-teeth 19 on the inner side of a slide 17, slidable longitudinally in a groove in the base-plate 15. The ensuing movement of the slide causes further rack-teeth 18 at its end to rotate a pinion 40 fixed to the forked arms 23 on the end of the clamping- plate or to a pin 21 which pivots the arms to a lug on the base plate. The clamping-plate 24 is thus swung to the open position, Fig. 4. To avoid a tendency to jam during initial engagement, the teeth 36 on one side of the plunger are omitted. The base-plate 15 carries positioning-lugs 26 passing through apertures in the guard and blade, and apertures or recesses in the clamping-plate. The lugs 26 have shoulders 27 forming a support for the clamping-plate. In a modification, also shown, the flanged upper end of the rod 12 carries incomplete bevel teeth which in the retracted position come into engagement with a bevel wheel on the end of a shaft journalled longitudinally in the base-plate 15 and connected by bevel gearing with the pivot-pin 21 of the clamping-plate. The form shown in Fig. 11 uses a longitudinal slide 17 having at one end an internal cam surface 52 engaged by a pin 53 on the clamping-plate arms 23. The slide is moved by engagement of a single tooth 54 on the rod 12 with a single notch in the slide. In order to provide a sharper and more accurate mesh of the tooth and notch, the rod 12 is connected to the handle 11 also by a quicker thread 50 which comes into action immediately after the simultaneous freeing of the threads 28, 13.

As shown, the patientsupport plate 64, Fig. 1, is mounted on rotatable shafts 62, 63 supported in plates 58, Figs. 1 and 2, and 59, Fig. 1, above the film plane F in the frame 6. The shafts 62 and 63 are movable with respect to their supporting plates 58, 59 to left or right for the view of Fig. 2, providing transverse movement of the support plate axis with respect to the surface of the frame 6. Movement of the support plate towards or away from frame 6 is produced by rotation of the supporting arms 56, Fig. 2, and 57, Figs. 1 and 2. These arms are rotatable about a shaft housed in a member 55, which is itself mounted for axial movement with respect to housing 51, to permit longitudinal movement of the support plate with respect to the frame 6. The housing 51 is rotatable about pivots 49, 50 located near one of its ends, and defining a vertical axis in Figs. 1 and 2, to permit transverse orientation of the support plate longitudinal axis with respect to frame 6. Details of the mechanism for producing the various movements are given. The support plate is detachably mounted on a pair of plates (620, 630, Fig. 5, not shown) by the projection of spring-loaded bolts into holes in the plates, permitting ready interchange of support plates, and the securing of a patient to the plate before insertion into the apparatus. The support plate may have crenellated edges (Fig. 3, not shown), or be provided with a slideway adjacent its edges, to facilitate the use of belts or other patient restraining means. The X-ray tube 20 is supported from a pair of columns 21 and 23 which are pivotable to form a deformable parallelogram, further links 32, 34, and 33 forming a tomographic arrangement, the link 33 being rotatable about pivot 27 on column 23, and about a vertically adjustable pivot 35 on the main frame of the apparatus, the lower end of the link being coupled to the film cassette. The whole apparatus is rotatable into a vertical position by the toothed sector 8 (Fig. 4, not shown).
