Title: Improvements relating to flexible band drives
IPC: B23F5/22
Filed: 1965-06-17
Abstract: 1,068,786. Gear - cutting. GLEASON WORKS. June 17, 1965 [July 22, 1964], No. 25670/65. Headings B3B and B3L. [Also in Division F2] Oscillatory motion is transmitted to a driven member from a reciprocatory or oscillatory driving member through a positive flexible band drive and through a friction drive. As shown applied to a gear-generating machine of the type described in Specification 1,066,692, flexible steel bands 19, 21 are anchored to a sector 24 fast with a tool-carrying cradle 2 oscillatable about an axis 3 and to a slide 15 reciprocated on a guide 17 which is pivoted at an end 18 to the machine frame and is biased upwardly at its other end by a spring- loaded piston 64 to urge surfaces 59, 58 (Fig. 2, not shown), on the slide and on the sector into frictional engagement. The spring pressure can be adjusted by a screw and generally is such that the friction drive bears the major portion of the load, the bands serving to maintain the desired phase relation; if desired. the pressure may be reduced so that the friction drive bears a minor portion of the load and serves for damping oscillations or vibrations in the band drive. In a modification, the surfaces 58, 59 are omitted and the friction drive is by way of the surfaces of the sector and the slide and the bands. In this case, it is preferred to form a slight clearance between the surfaces of the sector and slide and the inner band 21 so that the friction drive is transmitted through the outer bands 19. The slide 15 is reciprocated with variable amplitude by a variable length lever arrangement 8-12 which is oscillated by a cam 7 on a driving shaft 1. The slide 15 is connected by a variable length lover arrangement 31-37 to a rod 30 which is thus reciprocated. The rod 30 is connected by a screw-andnut device 38, 39 with a shaft 41 which is thereby oscillated. The shaft 41 is geared to a side wheel 44 of a bevel planetary gear having a side wheel 46 geared to a work spindle 4. Indexing of the work spindle, to bring successive tooth slots of a work gear into cutting position, is effected by a mechanism 54 whose output shaft 55 carries bevel planetary gears 45. The mechanism 54, which may be hydraulically operated, is controlled by a valve 56 actuated by a cam 57 on the shaft 1. The valve 56 also supplies hydraulic pressure to retract the piston 64 against the pressure of its spring to disengage the friction drive. In a modification (Figs. 6 and 7, not shown), drive is transmitted from one oscillating sector to another by band and friction drives.

Abstract: 718,522. Course-recording apparatus. SPERRY CORPORATION. Nov. 9, 1951 [Nov. 15, 1950), No. 26291/51. Class 97(2) [Also in Groups XXXV, XL(b) and XL(c)] Apparatus for delineating the course of a craft comprises on the craft a chart and a recording head, the position of the head being controlled by radio signals received from a fixed station and determining the position of the craft with reference to the station. The apparatus, Fig. 7, comprises a table 77 which is rotated with respect to the craft so that a reference direction on the table always indicates true North and a stylus 183 is moved over the table so that its position corresponds to the position of the craft with. respect to the fixed station. Fig. 2 illustrates the application of the invention to automatic following of a prescribed course and shows apparatus similar to that of Fig. 7 in greater detail. The table is supported on a shaft 81 mounted in a bearing attached to a fixed portion 85 of the craft. The shaft 81 is rotated in accordance with the heading of the craft by means of a compass repeater motor 71, so that the table always assumes a fixed orientation in space. A motor 25 whose output shaft is rotated in accordance with the azimuth of the craft from the fixed station is mounted upon a further table or " azimuth deck 89 which is mounted loosely upon the shaft 81, the motor being' coupled to the shaft through the gears 91. The azimuth deck is consequently rotated with respect to the table 77 through an angle corresponding to the azimuthal position of the craft with respect to the fixed station. A cursor 93 carrying the stylus 183 (see also Fig. 7) is supported by guide rods 95 which are mounted upon stands secured to the azimuth deck 89. The cursor is driven along the guide rods by means of a motor 47 which is controlled in accordance with distance of the craft from the fixed station, the cursor being attached to a cable 106 which passes over a pulley 101 driven by the motor 47. The stylus is thus positioned above the table 77 radially in accordance with the distance of the craft from the station and angularly in accordance with azimuthal angle of the craft with respect to the station and consequently indicates by its position on the table the position of the craft with respect to the station. The stylus traces the course of the 'craft upon a sheet of electrical recording paper placed on the table, the current to the stylus being continuously interrupted by means of a camcontrolled switch 187 so that a broken line trace is formed. The table may be mounted vertically so that the arrow 191<SP>1</SP> hanging vertically indicates the heading of the craft. Specification 718,589, [Group XXXV], is referred to.

A push-button tuner comprises a pushbutton rod 1 and a setting plate rod 2, both slidable in a housing 3, rod 2 carrying a setting plate 14 pivotable about point 15, a locking member 17, 18 for locking the setting plate in any desired position to enable the tuner to select a desired frequency, and a cam 16 co-operating with the locking member to effect locking of plate 14. Cam 16 carries pins 21, 22 engaged in a longitudinal slot in rod 2 for relative sliding thereon. Pin 21 extends to engage in an oblique slot in rod 1. To set the apparatus push-button 13 is depressed, causing both rods to move, cam 16 abutting locking member 18 at 18b, until plate 14 meets a tuning treadle 20, pre-set to the desired frequency. Plate 14 then rotates to the required position, and as button 13 is further depressed, cam 16 is forced under portion 18b of member 18 to press member 17 against plate 14 and hence lock plate 14 in the position selected. On releasing pressure on button 13, it returns to its original position under the effect of spring 11. When the button is subsequently depressed, the locked plate 14 causes treadle 20 to rotate to select the desired frequency. The oblique slot in which pin 21 of cam 16 engages in rod 1 causes, on depressing button 13, rod 2 to be deflected to abut the edge of the slot in which rod 2 slides in housing 3, so that rod 2, and hence plate 14, assumes precisely the same position each time the apparatus is actuated.
