Title: An improved cleaning and stropping machine for safety razors
IPC: B24D15/08
Filed: 1920-11-18
Abstract: 167,990. Kennedy, E. N., and Kennedy, G. A. Nov. 18, 1920. Stropping - apparatus.-Comprises a combined cleaning and stropping machine for the safety razor described in Specification 165,488, [Class 30, Cutlery]. The razor comprises a clamping- plate a, Figs. 1 and 10, having a longitudinal groove r, two blade-positioning studs b, Fig 4, and a central stud c screwed to receive the handle o. A guard-plate e is slidable along a retaining-plate k, which has slots m therein to allow the parts to assume the position shown in Fig. 4. The cleaning and stropping machine comprises a casing 10, Figs. 6, 7 and 10, in which are journaled two pairs of shafts 16, 17 rotatable, through gearing, by a crank 20 having a foldable handle 21. The shafts carry stropping-rollers 23, each having about one-half of its circumference covered with stropping-material 24, and spiral cleaning-brushes 25 each forming about two-thirds of a cylindrical brush. In the lid 11 of the casing is a slot 12 along which the handle of the razor is slid, and between the rollers and the brushes is a transverse partition 26 having therein a vertical slot 27 communicating with an horizontal aperture 28; a stop 15 is provided in the slot 12. A longitudinal guide-bar 29 is adapted to be engaged by the groove in the clamping-plate of the razor, and above the bar are a pair of parallel guides 29a shaped at 29b to retain the blade and the clamping-plate between the stropping-rollers. Rubber or like scrapers 31 are mounted in holders 32 slidable into the aperture 28 to remove soapsuds &c. from the blade as it is moved into position for stropping. Adjacent to the brushes are plates 36 slidable from above in guides 37 and having slots therein formed with brush-scraping edges 38 and guiding-edges 39, whereby refuse scraped from the brushes is deposited in troughs 40 mounted on or formed integral with the plates 36. At the front end of the casing a felt or like pad 44 is provided in a slot 43 to wipe the clamping-plate and the blade as the razor is moved into and out of the machine. A trough 47 is provided for spare blades. In operation, the razor is inserted in the slot 12 and the handle o is partly unscrewed. The razor is then moved inwards along the slot until it reaches the stop 15; the guard-plate e is, during this movement, detained between the brushes by the holders 32. The handle is then rotated, the brushes clearing the comb-like edges s of the guard-plate and the rollers stropping the blade. A ratchet may be provided to prevent rotation of the rollers &c. in the wrong direction. Leaf springs may be provided on each side of the slot 12 to press down and maintain the clamping- plate on the guide-bar.

Patent GB-464704-A (GB)
Title: Improvements in or relating to a manner of withering tea leaf and apparatus therefor
IPC: F26B25/00
Filed: 1935-11-25
Abstract: 464,704. Tea - withering. LORNIE, J. S. Nov. 25, 1935, No. 32659. [Class 34 (ii)] The leaf to be withered is spread on three or more superimposed surfaces formed of a continuous flexible band adapted to be traversed and forming a rack of surfaces, all the surfaces travelling simultaneously as the spreading proceeds, the leaf being spread on some of the surfaces from one end of the rack and on the remaining surfaces from the other end of the rack, after which movement is discontinued and the leaf is withered, being subsequently discharged. In the construction shown, a continuous length of canvas 1 is supported in zigzag fashion on rollers 2, 3 to form a rack of spaced superimposed withering surfaces on which tea is to be spread. The two ends of the canvas are connected to chains 8 which pass round sprockets 9 to a driving sprocket 10. Sprockets 11 are engaged by the chains to drive the rollers 2, and idler sprockets 12 are provided which may be adjusted to alter the tension of the chains. Each horizontal surface of the rack is provided with a slope at each end, and rotary spreaders 24 are provided whereby the tea as it ascends the slopes is spread out uniformly. The arrangement is such that when the driving sprocket 10 and the spreaders 24 are set in operation, the tea is spread on the horizontal surfaces from both ends of the rack, one set of alternate surfaces being supplied from the other end. When the available surface is covered with tea, the movement of the canvas and spreaders is stopped to enable withering of the tea to take place, after which the canvas moves in a reverse direction to discharge the withered tea. The spreaders consist each of a square shaft to which four paddles are fixed. Trays 37 are provided on each side of the rack of surfaces, these trays being pivoted and counterweighted so that they may be tipped up or down to feed or discharge the tea to or from the canvas 1.

Title: Improvements in friction gears for transmitting motion between two shafts or the like
IPC: F16H13/14
Filed: 1922-11-30
Abstract: 189,799. Erban, R. Nov. 30, 1921, [Convention date]. Friction gearing.-In epicyclic or other friction gearing employing planetary or idler balls or rollers, pressure between the working parts varying with the load is produced by transmitting the power through means such as cam surfaces and balls producing an axial reaction. In the form shown in Fig. 1, planetary balls 3 engaging studs 9 on the driven sleeve 13 engage a ring 2 secured in the casing 11 and a driving-sleeve 1 loose on the driving-shaft 12. Balls 4, 6 engage symmetrical or unsymmetrical inclines x on the sleeve 1, on a loose sleeve 5, and on a sleeve 7 splined on the shaft 12 and supported bv a thrust bearing 10. The arrangement of the balls and sleeves is such as to allow a cardan-like adjustment of the pressure of the balls on the sleeve 1. A spring 14 produces initial frictional engagement of the gearing parts. In the modification shown in Fig. 2, two sets of balls 3, 3' driving one or two sleeves 13 engage a spherical outer ring 2, or two rings with spherical outer bearing- surfaces, and two inner sleeves 1, 1<1>, which are pressed apart by incline and ball devices 4, 4<1> and by springs 14, 14<1>. The sleeves 1, 1<1> may be pressed towards each other to engage a single set of balls or rollers. The sleeve 13 may be stationary, the drive being transmitted between the parts 11, 12.

Abstract: 1357800 Flushing apparatus J L GIBBS and J W GIBBS 14 July 1971 32985/71 Heading E1C A flushing system, particularly for a W.C., comprises a hermetically sealed tank of rectangular form having a cut-away portion 11; a feed pipe 16 to the tank constantly supplied with water under pressure; a discharge valve assembly consisting of a tube 28, the lower portion of which communicates with the tank via an opening 29, a valve 34 which is carried by a vertically slidable rod 38, and a rolling diaphragm-piston assembly 44, 47 secured to the rod 38 for sealing the lower portion of the tube 28 from the upper portion, which is vented to atmosphere via an orifice 42; and a check valve-controlled air vent formed by a tube 18 extending from an inlet, formed by two apertured discs 26, 27, which is outside through the top wall of upper tank portion 14, to a point in the lower tank portion 12 between platform 15, formed by the cut-away portion 11, and the opening 29, and which incorporates a buoyant check valve 22 adapted to remain engaged with a seat 20 so long as the water level is above the level of the seat 20. Actuation of the discharge valve is effected by pulling a cable 54 connected between the rod 38 and a manually-operated handle (58, Fig. 1, not shown). When this handle is released to close valve 34 after the tank has been emptied, a spring 62, bearing against an adjustable collar 60 on the rod 38, maintains the valve 34 slightly open until the water level in the tank has risen sufficiently. for water pressure to overcome the spring 62 and fully close the valve.
