| 81 | Auxiliary manual drive for motor driven wheels - uses handle with chamfered end to disengage keys from shaft for location in handle slot | FR7528788 | 1975-09-19 | FR2324942A1 | 1977-04-15 | PELLETIER BERNARD; THENON CHRISTIAN |
| A gear or pulley wheel (3) is freely mounted against a shoulder (2) on a motor driven shaft (1). The end of the shaft has keyways (10) in which register radially sliding keys (4), mounted in slots (5) in an extension of the wheel hub. Normally, a wire spring (7) forces inwards to engage the keyways and transmit drive from shaft to wheel. The extension of the hub is counterbored (13) for the introduction of the handle shaft (11), the latter itself being bored (12) to fit over the end of the main drive shaft. The outer surface of the handle shaft is provided with keyways (15) the same width as those on the main shaft. Both handle shaft and keys are chamfered (16, 17) so that the keys are disengaged from the main drive keyways, when the handle is inserted, the keys then relocating in the handle keyways, coupling the handle to the wheel. | ||||||

| Device comprises a T bolt shaft on which an eccentric member rotates, the member having one end of the reciprocating drive arm rotatably mounted on it. A differential gear rotates the eccentric via a first gear secured to it and a second gear on the T bolt shaft, the arrangement thus changing the length of the stroke. The device has a min. number of components and is compact in construction. The device is also efficient in operation and is self contained. Quick and easy adjustment of the feed is possible on the micro scale. | ||||||

| 1,247,497. Linkwork. BENDIX CORP. 24 Sept., 1969 [30 Sept., 1968], No. 47091/69. Heading F2K. A linkage for converting angular movement of an input shaft 12 to linear movement of an output rod 38 pivoted to an intermediate shaft 22 parallel to the input shaft 12 by an eccentric pin 36, comprises a bifurcated lever 12a rigid with the shaft 12 and movable between stops 40, 42 in a housing 10, a block 20 on a pin 18 pivoted to the lever 12a being slidable in a longitudinal channel 28 of a lever 22a rigid with the intermediate shaft 22, such that when the lever 12a is midway between stops 40, 42 the pin 18 is close to the shaft 22 axis. Initial movement of the lever 12a from the mid-position shown (Fig. 2) causes rapid movement of the lever 22a to a maximum displacement. Further movement of lever 12a causes reversal of lever 22a and a slow movement towards the midway position. Thus the full displacement of lever 22a, and hence of the rod 38, takes place in approximately the initial eighth of the lever 12a travel. The pin 18 extends through slots 30 in the sides of the lever 22a. The linkage is used in a feedback mechanism controlling a servo valve in an aircraft control surface actuating system. | ||||||

[Also in Division F1] In an engine valve timing control system the crank-shaft 11 and cam-shaft 17 are connected by chain and sprocket gearing 12, 13, 16, the sprocket 16 having a spline connection 36 with a disc 21 connected by a ball spline joint 56 with a second disc 39 secured to cam-shaft 17. Ball 56 engages straight and helical splines 53, 52 in annular members 38, 51 secured to discs 39, 21. A chamber 57 formed between the discs is supplied with pressure oil through passages 61, 66 under the control of a follow-up spool valve 76 actuated by a fork 82 connected by a linkage (103, 116) to a servo piston (99) in the engine manifold (97), Fig. 1 (not shown). Actuation of the piston and valve 76 result in axial movement of disc 21 and conjoint rotation of disc 39 to vary the phasing of cam-shaft 17. | ||||||

| 1,225,497. Milling screwthreads; grinding; turning. S. J. ROYLE. 10 June, 1968 [23 June, 1967], No. 29183/67. Headings B3D, B3K and B3T. Mechanism for adjustable-rate axial feed of a rotary spindle B comprises an angularly adjustable setting rod F which lies in a plane intersecting the spindle axis at a variable angle depending on the setting of the rod, the spindle B being axially fed at a rate determined by the setting of the rod F by means wherein relative motion between the rod F and a bearing member E slidable therealong causes displacement of the spindle. As shown, the spindle B is rotatably and slidably supported in a bearing A on a base K which is attached to a surface grinding or milling machine table to enable a screwthread to be cut on a workpiece J by a rotating cutter or grinding wheel G. The spindle B is driven through bevel gears H from a drive spindle C mounted in a U-bracket M carried by the spindle B, the setting rod F is pivoted at the centre of curvature of an arcuate scale D1 on a quadrant member D which includes a bar D2 slidable in the U-bracket M and has a nut portion engaging screwthreads on the drive spindle C, and the bearing member E is releasably positioned in an arcuate slot E1 in the base K to allow the rod F to be positioned anywhere on the scale D1 by means of a clamp D3. When the drive spindle C is rotated by means of a star wheel C1 the spindle B and workpiece are rotated and the nut advances along the spindle C to displace the quadrant member D transversely of the spindle B so that the bar F slides through the bearing member E to displace the quadrant member D, bracket M and spindle B together with the workpiece J longitudinally of the spindle axis. In Fig. 2 (not shown), the drive spindle C is driven by an electric motor through a belt drive. The setting rod F and bearing member E may be curved so that threads of varying pitch can be produced. In another embodiment, Fig. 3 (not shown), two setting rods permit selective movement of the spindle in either axial direction, and there is provided a scroll-cutting attachment comprising a turntable which is driven through bevel gears from the spindle and moves with the spindle in relation to a fixed tool. In a further embodiment, Fig. 4 (not shown), the setting bar is carried by a graduated turn-table connected by pivot means to a fixed base. | ||||||

| 1,179,050. Linkwork. HAMMOND MACHINERY BUILDERS Inc. 17 Oct., 1967 [2 Dec., 1966], No. 47162/67. Heading F2K. [Also in Division F1] An adjustable stroke reciprocating drive, e.g. for oscillating an electrochemical grinding wheel G, comprises a reciprocating power unit 16, e.g. an hydraulic piston and cylinder, carried by a rotatable shaft 18, Fig. 4, and coupled through a piston-rod 49, pivot 59, pitman 17 and pivot 62, Fig. 1, to the operating arm R of grinding wheel G, the effective stroke imparted to arm R being adjusted by rotating shaft 18 to swing the power unit 16 between the minimum and maximum stroke positions A and B. Rotation of shaft 18 is effected manually by a knob 28 acting through a worm and pinion, the meshing of the pinion with the worm being adjustable by rotation of an eccentric bush, Fig. 5 (not shown). The swinging movement of the power unit is limited by adjustable stops 31, 32. Pivot pin 59 carries rollers 61 running between housing guides 64, 66, Fig. 1 and Fig. 3 (not shown). Flats 67, 68, Fig. 4, on pivot pin 59 actuate bleeder valves 69, 71 at the end of each stroke to actuate a reversing valve for power unit 16. Tapered portions 52, 53 on piston 39 enter cylinders 54, 56 to stop the piston at the end of each stroke. | ||||||
