Patent GB-858710-A (GB)
Title: Improvements in or relating to lathes and other machine tools
Inventor: HAYWARD ALBERT JOHN
IPC: B23Q5/16
Filed: 1957-11-12
Abstract: 858,710. Lathe details. COHEN 600 GROUP Ltd., G. Nov. 12, 1957, No. 35226/57. Class 83 (3). [Also in Group XXXIV] A lathe or other machine tool is provided with an infinitely-variable friction drive which is coupled to the cross-slide feed to give constant cutting speed during facing operations. The friction drive may be of a known type or may be as described in Specification 858,708. In an embodiment of the invention, a friction drive has the speed-ratio adjusted by rotating a plate 31, Fig. 1, having curved depressions corresponding to the tiltable spherical driving elements 5, and curved slots 15 into which fit the ends 14 of the spindles on which the driving elements rotate. The plate 31 is rotated by a central spindle 32, which is coupled to a torsion bar 58, Fig. 3. When the friction-drive device is stationary there is high resistance to adjustment, so the torsion bar stores energy equivalent to the amount of adjustment required, which is taken up by the latter when it starts rotation. The cross-slide 67 carried by a saddle 68, has a rack 72 which moves a gear 70 on facing movement. A shaft 71 has a slidable key connection to the gear 70, and thus rotates, through change wheels 73, 74, a gear 78 rotatable on the end of the torsion-bar 58. The gear 78 is fixed to, or integral with, a notched disc 63, and an arm 55 fixed to the torsion bar carries a spring-pressed plunger which engages the notched disc. Motion is thus transmitted from the cross-slide to the torsion-bar. A handle 57 connected to the spring-pressed plunger moves through a gate or slot in a fixed plate 59 between stop limits according to the amount of adjustment of the plate 31. The handle 57 may, therefore, be pre-set to give a desired starting speed for the drive, which setting is taken up when the drive commences. When operations other than facing at constant cutting speed are to be carried out, one of the change-speed wheels 73, 74 is removed and a locking-pin 77 inserted to maintain the wheel 78 stationary. The notched member 63 is thus also locked and may be used to position the torsion-bar by the handle 57. An arrangement of notched disc 82 and locking plunger 81 may be employed at the end of the torsion-bar adjacent the friction drive, so that the latter may be locked to give a particular drive-ratio, and the other end of the torsion-bar pre-selected for a new drive-ratio. When the new ratio is required to operate, the plunger 81 is withdrawn and locked by a knob 85. Specifications 618,774 and 858,709 also are referred to.

Abstract: 387,483. Coin-freed vending-machine. GRIFFITH, M. N., 12, February Street, Chorlton-on-Medlock, Manchester. Dec. 30, 1931, No. 35962. [Class 27.] Articles stored in piles.-A coin-freed vending- machine comprises a plurality of adjacent magazines h, Fig. 4, containing packages movable laterally from the bases thereof by an ejector arm j which is slidable to any desired position on a square shaft m and is rotated therewith to 'eject the selected package, after which it is returned to its initial position by a spring, a pivoted catch p permitting it to slide freely beneath the packages. As shown, the magazines h have rear flanges i cut away at the bottom to permit the delivery of the articles, which are surmounted by weights k incapable of ejection. The setting of the ejector j is effected by means of an external member carrying a pointer which moves over a scale. In a modification, Fig. 17, the pointer f is moved inside the machine by an endless band actuated by a knob, and is visible through a glass panel 31. " Empty " notices, displaying.-In the latter -construction, a plurality of indicating discs 291 working in conjunction with the pointer fare pivoted on members 29 resting against the piles of articles ; when these are exhausted, the particular indicator drops and discloses an " empty " notice 32. Coin action, weight; multiple coin.-A coin 15 passing down a shoot w, Figs. 8 and 10, depresses a platform 26 on a pivoted arm 12 carried by a member y which is loose on the spindle s of an external handle c, but which is coupled by a strong spring z with a member u clamped to this spindle. Rotation of the spindle s by the handle c causes the member u to move, and through the spring z to carry with it the member y, against the action of a weaker spring 17. The weight of the coin 15 on the arm 12 has moved the end thereof up into such a position that when the member y is moved it will engage a projection 13 on an arm q carried by the shaft m, thus actuating the ejector mechanism. When the arm 12 is moved from under the shoot w, the coin 15 falls into a money box, but a projection 14 on the arm 12 prevents its disengagement from the arm 13. At the end of the stroke, an abutment 19 on the member u carries the member y back with it, thus disengaging the projections 13, 14 and allowing the arm 12 to assume its original position, after which a projection 16 on y engages q and resets the ejector mechanism. According to the Provisional Specification, more than one coin may be used for each actuation, all the coins but the last engaging deflectors. Returning coin.-If a particular magazine is empty, the ejector j engages the weight k and thus prevents motion of the members q, 12, y; the member u, however, can still move by extending the spring z, and when at the end of the stroke a sector v thereon uncovers a slot 20 in an external shoot g, the coin 15 falls through into a cup 21.
