Title: Improvements in or relating to worm gearing
IPC: F16H55/22
Filed: 1931-02-20
Abstract: 367,564. Worm gearing. HOLROYD & CO., Ltd., J. and WALKER, H., Perseverance Works, Harbour Lane, Milnrow, near Rochdale. Feb. 20, 1931, No. 5348. [Class 80 (i).] A worm 1 of the parallel type has a thread which is generated, while the worm rotates about its axis, by a straight cutting edge 2 which lies in a plane not containing the worm axis, and which turns about an external axis 3 which is traversed along a path parallel with the worm axis. The movement axially of the worm may be imparted to the worm itself instead of to the axis 3. The axis 3 always lies in a plane perpendicular to an axial worm plane containing a diameter 5, Fig. 4, or 10, Fig. 5, and may be either normal to or inclined to the axial worm plane. The cutting edge may rotate at a radius 6 in a plane parallel to but offset from the diameter 5 as shown in Fig. 4, the rotation being in an anticlockwise direction in unison with the axial run of the thread produced by rotating a left-handed worm in a clockwise direction when viewed from right to left, Fig. 1. The speed of the cutting edge at its pitch radius 6 equals to speed of the axial run of the worm thread plus the speed of bodily axial displacement of the worm, the latter being a slow feed movement so that a number of cutting edges such as 2 may make successive cuts of normal depth during the generation. The opposite thread face is shaped in a similar manner, the plane of the cutting edge being equally offset on the opposite side of the diameter 5. In a modification, the worm may be moved bodily for the feed movement in the opposite direction to the run of the thread, the speed of the cutter rotation being correspondingly modified. In another modification, Fig. 5, the cutting edge may be inclined to the axial worm plane 10. In some cases the plane of rotation of the pitch radius 6 may coincide with the plane 10, the cutting edge having different obliquities for cutting the respective thread faces. The conjugate worm wheel may be generated by a tool having cutting edges similar to the worm described above and rotating at the correct speed relative to the worm wheel blank. The pitch radius of the worm wheel may be equal to, greater than, or less than, the distance between the pitch helix of the worm and the axis 3.

Abstract: 591,723. Boning fish. ATLANTIC COAST FISHERIES CO. March 8, 1945, No. 5824. Convention date, March 8, 1944. [Class 28 (ii)] The dorsal fins and associated bones and joints of fish are removed by a pair of mutually inclined circular rotating knives 36, which makes incisions along both sides of the dorsal fins, the machine having means to grip and continuously pull the cut strip downwardly out of the way. Such gripping means comprise scrolls 38, Fig. 9, formed on one face of each of the knives 36, the scrolls comprising spiral ribs 160, Fig. 7, with preferably tapered cutting edges forming helical grooves 162, and lead-ins 164 combined to form a truncated cone. Each knife 36 is mounted on an inclined shaft 26 axially adjustable and driven by an internal gear 22, containing and engaging the driving gear 20 on the shaft 18 on an electric motor 16. The knives are timed to approach each other up to their spaced cutting position by mechanism coupled to the feed of a fish towards the knives, which causes each knife-carrying sleeve 44 to slide on its shaft. A decapitated fish, back down and tail leading, is placed in a trough 223, through which it is fed by grippers 216 traversed by conveyer chains 207, and guided by inclined yielding guides 224. The fish is carried past a fin straightener 233 and a grooved roll 250 which presses on the belly. The fish then passes to the fin-removing knives 36 which are first spaced to allow the tail to pass between them. A yoke 92 is then actuated to slide a sleeve 68 and its shaft 26 axially slightly to move the knives 36 towards one another to cut the flesh and remove the fins, the free end of the cut-out strip passing into one of the lead-ins 164, whereby it is pulled down and removed, the scrolls 38 milling the skin of the strip. Each dorsal fin joint is accommodated in the helical grooves and fed downwardly. After removal, the yoke 92 is actuated by the conveyer to open the discs for the next fish. The head 116 of a lever 112 may be manually depressed to move the sleeve 68 and knife shaft to the left to separate the knives and so allow of their easy replacement. Specifications 452,688 and 466,674 are referred to.

Filed: 1929-02-22
Abstract: 306,516. Loeb, O. Feb. 22, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Projecting appliances.-A ball-throwing appliance for games, more particularly for tennis, comprises an automatic feeding device which brings the balls singly from a hopper into the throwing position, in combination with a spring controlled striking device which, after release, suddenly delivers a blow to the ball presented in the throwing position. The balls, dropped into a hopper 17 are fed singly to a vertical channel 24 by the vanes 23 of a cone 18 rotated by a motor 20. A cam 30 actuated by the motor engages an arm 29 and thereby draws back a striker 27 against the resistance of a spring 31. Continued notation of the cam releases the striker which then projects the ball through a delivery tube 25. The appliance may be adjusted about pivots 6, 11 to change the vertical and horizontal directions of flight of the ball; the height of the delivery tube may be adjusted by raising or lowering a rod 2 in the tripod or other stand 1. A pair of spring-pressed flaps arranged in front of the ball, and a pin 33 behind, retain the ball in readiness for projection. A sleeve 38 carrying a spring-pressed flap 36 may be adjusted along and around the tube 25 so as to deflect to a variable extent the projected hall and to impart spin thereto. The device may be operated by hand instead of by motor. By using different cams 30 definite variations in the projection of the ball may be obtained. The striking device may be replaced by a motor-operated fan supplying a blast oi air to the delivery tube.

Title: Improvements relating to pilot valve mechanism
IPC: F16K24/04
Filed: 1956-02-27
Abstract: 797,115. Fluid-actuated valves. BRISTOL CO. Feb. 27, 1956 [March 2, 1955], No. 5998/56. Class 135. A pilot valve mechanism having an orifice 27 controlled by a member 35 whereby to control the position of a valve member 20 which is actuated by a piston 31 of rubber &c. and controls communication between an inlet 16 for pressure fluid, such as air, and an outlet 17 leading to a diaphragm motor or there actuator to be controlled is provided with a closure member 34, e.g. of rubber &c., carried by a wire stem 33 extending through a bore in the stem 30 of the valve member 20 and arranged to seat at the lower end of the stem 30 to prevent wastage of air by leakage through the orifice 27 when the member 35 is displaced from that orifice. With the parts positioned as shown, the connection 17 to the diaphragm motor is vented to atmosphere through an annular space surrounding the stem 30 and openings 28 in a cap 19 which constitutes a cylinder for the piston 31. When the member 35 is depressed it engages the stem 33 of the valve member 34 to open the latter and admit air under pressure to the space above the piston 31, at the same time closing the orifice 27 so that the piston is depressed by the pressure above it to open the valve member 20 and engage a seating 24 so that the diaphragm motor is connected to pressure air and the communication with atmosphere is cut off. When the member 35 is again moved away from the orifice 27 the valve member 34 is urged to its seating at the end of the stem 30 by air pressure and the piston 31 is urged upwardly by the pressure of air acting on the surface radially inwardly of the seating 24. The wire stem 33 is kinked at 36 to limit its axial movement in the stem 30. In a modification, the upper end of the stem 33 carries a cap which is engaged by the member 35 and coacts with an upstanding annular seating on the cylinder 19. The invention is stated to be applicable also to pilot valves actuated by a diaphragm or of the kind in which a piston valve is directly actuated by air pressure on one end in opposition to a spring force. Specification 783,927 is referred to.
