Title: Improvements in or pertaining to the trueing of valves, and valve seatings and meanstherefor
IPC: B24B15/00
Filed: 1925-03-11
Abstract: 253,193. Bowley, A. S. March 11, 1925. Block, rubber, and like apparatus; tools. - A device for trueing valevs and valve seating comprises a hollow conical member V, Fig. 4, made from sheet metal in a press or by turning from the solid. The base of the member is perforated at A. A shaped strip of abrasive material W having an adhesive backing is secured inside the member V and another adhesive, strip may be secured to the outer surface of the conical member. For trueing a valve, the valve stem is passed through the opening A and the whole assembly is mounted in the valve seating and the valve rotated, the adhesive exterior serving to prevent rotation of the conical member. For trueing the seating, the abrasive is fastened to the conical member and the inside is made adhesive so that in operation the conical member rotates with the valve to move the abrasive over the seating. The adhesive is preferably of a non-drying variety such as is used in surgical bindings. In a modification, the conical member may be held in the hand while a valve is trued and in this case the outer adhesive element is not required. In another modification, a washer W made of abrasive material and adapted to be bent up to conical form may be positioned directly between the valve and the seating. For trueing the valve, the washer is caused to adhere to the seating and the valve rotated over the abrasive surface, while for trueing the seating, the abrasive surface is presented to the seating and the valve is caused to adhere to the other surface. When, in using the conical member, extra pressure is required between the valve and the seating, a screwed collar O may be secured to the valve stem and nuts S may be adjusted to compress a spring N and draw the valve on to the seating U. In a further modification, Figs. 6 and 7, the conical member may be provided with lugs A<2> and instead of employing adhesives, a bar B<2> may be used for holding the conical member whiles a valve is trued. For trueing the seating, a driver F is fitted with a cross-bar Z engaging the lugs.

Filed: 1936-03-09
Abstract: 458,638. Screw propellers. LEVASSEUR CONSTRUCTIONS AERONAUTIQUES, P., 17, Place Felix Faure, Paris. March 9, 1936, Nos. 7052 and 7053. Convention dates, March 9, 1935 and Aug. 3, 1936. [Class 114] Variable-pitch screw propellers wherein the blades are movable under aerodynamic and centrifugal forces, a locking device is provided which acts solely in the direction of movement of the blade but which is releasable to permit such movement whilst reverse movement is effected against the action of the forces acting on the blade through a control which is in turn actuated by the energy of the members in motion. The blade 1 is screw mounted upon a stub 2 projecting from the main boss 3 of the propeller, and upon that blade root is provided a band carrying a projecting arm 12 having a roller 13. This roller is adapted to contact with a cam face 7 upon a ring 6 which is freely mounted on the boss. The action of the forces acting on the blades are partly balanced by an elastic cord 14 which is fixed at one end to the collar 8 and at the other end to a supporting member 15 carried by the hub. Normally the plate 6 rotates freely with the hub 3 with capacity for relative displacement but it can be held slightly by a brake. The relative movement is limited by means of stops 17, 18 co-operating with the projection 19. An elastic cord 20 constantly tends to bring the plate 6 back into a position corresponding to the large pitch position of the blade, in which case the projection 19 is pressed against the stop 17, the said elastic cord 20 being hooked at one end to a finger 26 carried by a collar 8 and at the other end to a finger 27 on the plate 6. When relative movement of the plate 6 is imposed by the brake, the roller 13 comes into contact with different portions 7 of the cam track and the pitch is altered. In order that the control may be effective for more than two set pitch positions, the cam path is formed with additional ramps and retractable stops are used for allowing the roller 13 to pass from one portion of the track to another.
