Abstract: 788,807. Belt gearing. NEW BRITAIN MACHINE CO. May 10, 1955, No. 13559/55. Class 80 ( 1 ). In a belt drive for the tool spindle 20 of a combined horizontal boring, drilling and milling machine the outer surface of the belt 39, Fig. 3, is cogged and is wrapped around and held in contact with toothed grooves in the driving and driven pulleys 38, 40 by idler guide rollers 46, 45, 47 and return rollers 48, 49. The location of the belt within the spindlehead C minimizes the overhang of the spindle 20, while the utilization of the outer surface of the belt enables it to be replaced without disturbing the spindle bearings. Preferably the pulley grooves are of the same depth as the belt thickness and the rollers 46, 45, 47 so positioned that they roll on the peripheries of the pulleys 38, 40. The rollers 47, 48 are supported in a yoke pivoting on a pin 70 coaxial with the roller 47, and the yoke is supported in a casing 63 by a screw 74 whereby the belt tension may be adjusted. The roller 49 is located between a shoulder and a snap-ring on a headed shaft 53 passing through the spindle-head housing wall 22 and held in a rib 54 by a snap ring. The rollers 46, 45 are supported by means similar to that for the roller 49. To facilitate installing a new belt the casing 63 and yoke therein are removed, and the roller shafts are shifted to allow the belt to be looped around the rollers. The driven pulley 40 is mounted on a spindle quill 23, Fig. 2, in which the tool spindle 20 is slidably keyed, the spindle being axially fed by mechanism not shown. The shaft of the driving pulley 38 carries a pinion 36 engageable by a gear pair 30-31 slidable on a shaft 32 which is driven through bevel gearing by a spline shaft 35 itself driven by a motor and change-speed gearing (not shown). Gears 27, 28 may be provided on the quill 23 and be engageable by the gear pair 30-31 to transmit low-speed drives independently of the belt gearing. It is stated that in other belt drives the externally-cogged belt may be replaced by a belt provided on its inner surface with interlocking means, such a belt being held in engagement with a pulley by idler means engaging its outer surface.

Abstract: 639,663. Fluid flow measurement. FALK, O. May 20, 1947, No. 13573. [A Specifcation was laid open to inspection under Sect. 91 of the Acts, May 20, 1947.] [Class 69 (i)] [Also in Group XXXVIII] In a flow measuring device, Fig. 1, a fluid stream exerts a hydrodynamic thrust on a spherical thrust body 6 (which may be a disc or cylinder) to rotate stirrup 5 and pivoted shaft 2 to open contacts 11, 12 and de-energize electromagnet 14. Armature 16 is released, allowing thrust roller 17 to press friction discs 18 to the right, so that the motor-driven drum 21 drives the left-hand disc to rotate shaft 9 which winds the coil spring 7 to balance the rotation of shaft 2 due to the hydrodynamic thrust until the contacts close, and the motor drive is transferred to the right-hand friction disc so that the spring is unwound until the contacts re-open. There is thus a continuous oscillation of the shaft 22 about a mean displacement position dependent on the hydrodynamic pressure exerted by the stream on body 6, and this displacement drives arm 24 between co-operating adjustable stops 26 to rotate a drum 32 on which a wire 33 is wound according to a law such that it traverses a recording stylus 37 over a moving paper strip linearly with variations in fluid velocity. The recorded course may be integrated to give the mean velocity over a period of time. In a modification, Fig. 2, inlet and outlet pipes 57, 58 are longitudinally and adjustably disposed in a main 50 and are connected through valves to the opposite sides of thrust discs 51, carried on an arm 52 rotating shaft 2, which twists a coil spring 7 against torsion produced by a reversible motor 67 controlled by a reversible relay 68 operated by the amplified output of a photocell 72, illumination of which is varied by a shutter 70 operated by an arm 69 carried by the rotatable shaft 2. The shaft oscillates as before about a mean displacement position dependent on the hydrodynamic pressure. The indications may be transmitted to a distance in linear dependence on the fluid velocity by means of a potentiometer device whose slide is traversed similarly to the recording stylus in Fig: I.
