Title: Improvements in or relating to devices for measuring the helix angle of helical gearwheel teeth
IPC: G01B5/20
Filed: 1947-04-21
Abstract: 640,647. Gauging toothed gears. LEUTHOLD, B. April 21, 1947, No. 10616. [Class 106 (ii)] The helix angle of the teeth of helical gearwheels is measured by apparatus comprising a feeler and a protractor consisting of a stationary and a relatively movable indicating element, the feeler and movable element being mounted and connected for joint rotation, and the feeler having a single plane measuring surface adapted, by rotation of the feeler with respect to the wheel axis, to be contacted with the flank of one of the teeth along a line of contact thereof, whereby the movable element is rotated through the same angle as the feeler, and the protractor is caused to indicate the angle of rotation. Racks with inclined teeth can also be tested by the apparatus. In the portable device for large wheels shown in Fig. 6, a feeler 5 is secured to one end of a shaft 3 mounted in a casing 2, the other end of the shaft having a disc 6 secured thereto bearing protractor graduations which can be viewed through a microscope 7. The measuring surface m of the feeler 5 is aligned with the axis x of the shaft 3. The casing 2 is laterally adjustable in a forked member 10a which is itself slidably mounted in a groove in a slide 9. The slide 9 is adjustable along a reference member 8 which is adapted to contact the machined side face of a gear-wheel 1. The casing 2 is guided in the fork 10a between opposed ball tracks and is laterally adjustable by screw means 12. To measure the pitch angle of the teeth, the reference member 8 is placed against the side of the wheel, the slide 9 adjusted until the feeler 5 is near to the flank of a tooth, and the appropriate screw 12 turned until the feeler surface m bears tangentially against the tooth flank. This contact rotates the protractor disc 6, and the pitch angle can be read through the microscope 7. In a modification, the reference member 8 is connected direct to the casing 2 and has adjustable supports which engage the tips of two gear teeth. In a further form, the casing 2 is secured for adjustment on a rod which has a V-surface adapted to rest on the shaft of the gear-wheel; a reference feeler also engages the side of the wheel. In the stand device shown in Fig. 10, small wheels are mounted between centres between two pedestals 21 adjustable on a base 20. A casing 23, mounted in slides 29 on the base 20 and adjustable by a screw 30, carries a rotatable shaft 24 on which is a protractor disc 6 which can be viewed through a microscope 7. The shaft has also secured thereto a flange 25 in which is a screw-adjustable slide 26 carrying a feeler 5. The axis y<SP>1</SP> of the shaft and the plane of the measuring surface m of the feeler 5 are in this case inclined at a small angle, preferably equal to the angle of obliquity of the teeth. In operation, the feeler is advanced between a pair of teeth by the screw 30, and then adjusted to the flank of a tooth by the slide 26.

Title: A new or improved construction of gas and air mixer and/or regulator
IPC: F23D14/48
Filed: 1924-05-03
Abstract: 239,256. Turner, E. (trading as Turner & Co., E.). May 3, 1924. Atmospheric gas burners. - In a gas and air mixer applicable for burners, one medium under high pressure is admitted to a chamber through a number of small orifices in a fitting and each stream is projected through a separate orifice in an ejector plate mounted upon a spindle or guide secured to the fitting, and induces a surrounding stream of the low-pressure medium, admitted behind the plate. The streams of mixture induce a current of low-pressure medium around the outer periphery of the plates. In one form, high-pressure gas is supplied to the funnel-shaped mixing-chamber a of a slotted tube burner k from a valve-controlled conduit c through orifices d in a fitting b and passes through larger, preferably tapered, corresponding orifices f<1> in an ejector plate f having a bevelled edge, air being admitted through a gauze-covered inlet g having a sliding regulator h. The plate f is slidably mounted on a guide e and is adjustable by means of a spring i in conjunction with a screw j having a crank arm or a cam j<1>. In a modification, Fig. 4, for use as a pilot jet, gas is supplied through an orifice r<1> into the fitting b t'o which the plate f is rigidly connected, air being admitted through orifices g below the plate f. An adjustable gauge rod m is provided to indicate the correct flame height.

[Class 38 (ii)] In a polyphase regulating transformer each of the core limbs 12, 13 or 14 corresponding to one phase of the primary winding is subdivided into a number (e.g. six) of parallel fluxpaths, and each phase of the secondary winding (one of which is shown in Fig. 4) is divided into a corresponding number of series-connected parts 20 ... 25 arranged one on each core limb. Each part is tapped, and the tappings are associated with fixed contacts arranged in sets corresponding to half the number of winding parts. Regulation is effected by movable contacts 26, 27, 28 which in the lower positions shown provide maximum voltage at the terminals 29, 30. Voltage is lowered by an amount equal to that of the section 34 by movement of the contact 26 one step. During this movement the section 34 is short-circuited, but circulating current is kept low by reason of the flux in the corresponding limb portion being diverted into the other five limb portions. Further regulation is effected bv successive movements of the contacts 27 and 28. The movable contacts may be interconnected by gearing adapted to effect the necessary cyclical movements thereof in regulating from maximum voltage to zero. The Specification as open to inspection under Sect. 91 comprises also the subjectmatter of Specifications 10986 /35 and 10987 /35. This subject-matter does not appear in the Specification as accepted.

Title: Pneumatic fastener driver
IPC: B25C1/04
Filed: 1962-03-22
Abstract: 938,449. Stapling machines. BOSTITCH Inc. March 22, 1962, No. 11000/62. Class 89 (3). A pneumatic tool 10 for driving staples or nails comprises a body 12 having a pressure cavity 16, a cylinder 50 having portions 72, 74 of different diameters, a piston 64 having portions 66, 68 defining therebetween, together with the cylinder, a chamber 78, a duct 90 connecting the pressure cavity with the chamber to thereby tend to urge the piston toward a first end of the cylinder, a driver 56 connected to the piston, and additional duct means 98 for connecting the cavity to the first end of the cylinder to drive the piston. The duct means 98 connects with an annular chamber 95 communicating with the portion 68 of the piston via an opening 96 and also with a chamber 26 controlled by valve 34. As shown in Fig. 1, the piston is maintained in a poised position due to the larger piston head 68 being in communication with the pressure cavity 16 via the duct 90. When the valve is opened by a trigger 20, compressed air flows from the cavity 16 through duct 98, and chamber 95, the air then leaking through the clearance space between an extension 100 on the piston 64 and a cylinder formed on an end-cap 84; the pressure then acts on the full diameter of the piston causing it to move rapidly. Upon release of the trigger, the valve closes and the air in the cylinder 50 is exhausted to atmosphere via chamber 95, duct 98, chamber 26, and axial grooves 108, Fig. 5, formed in a stem 30 of the valve; a head 32 on the valve prevents escape of air via the grooves when the valve is open. The piston returns to its poised position by means of the air pressure acting on the larger head 68, the extension piston 100, on entering its cylinder, providing a cushioning effect at the end of the stroke. The driver 56 is pinned in a screwed plug 60 and, by rotating the plug, the effective length of the driver may be altered.
