    摘要: A diaphragm for a diaphragm-type piston characterized by an S-shaped or ogee-like profile approximating a theoretical model that is substantially free of distortion in a selected position of the piston assembly in which a convolution is formed in the annular space between the diaphragm piston and the body in which the piston operates. Being molded without a convolution, the diaphragm lends itself well to maintaining a reinforcing fabric centrally embedded within the diaphragm proper, while at the same time being substantially distortion-free in a selected position of the piston assembly.

    摘要: A multi-thickness diaphragm member including clamping sections that are sized for assembly of the diaphragm in standard air brake valve devices and a flexure portion intermediate the clamping sections that forms a convolution during assembly. The thickness of the flexure portion is less than that of the clamping sections to facilitate formation of the diaphragm convolution without wrinkling, in order to alleviate progressive fatigue failure. The thin flexure portion of the diaphragm is joined with the respective clamping sections through a tapered area, which lies entirely outside of the annular space in which the diaphragm convolution forms during assembly, to thereby maximize the radius of curvature of the convolution for optimum utilization of the flexure portion in forming the convolution.

    摘要: A dual seal coupling fitting enables quick measurement of pressure. The fitting includes primary and secondary valves and has one end shaped like a male portion of a quick coupler and another end screwable into a threaded bore defined in a pressure bearing housing. The fitting defines first and second cylindrical sections in communication with each other. The primary valve situates in the first section, the secondary valve in the second section. The primary valve includes a valve stem with a poppet head. A first mechanism compresses the poppet head against an outer valve seat to close the primary valve thereby preventing leakage of pressure. The secondary valve features a cylindrical seat piece and a retainer. The piece secures within the second section and defines through itself an inner bore. The piece at one end forms an inner valve seat and at an opposite end situates adjacent the first mechanism. The retainer has at one end a post approximate a terminal end of the valve stem within the inner bore. The retainer also has a check valve retained within an annular recess defined about a base of the post. A second mechanism compresses the check valve against the inner valve seat to close the secondary valve thereby further preventing leakage of pressure. Mating a female portion of a quick coupler to the male portion opens the primary and secondary valves and enables quick measurement of the pressure via a gage attached to the other end of the female portion.

    摘要: A test connector for connecting an air brake test device to access ports provided on an air brake control valve device where such access ports are normally closed by check valves is disclosed. In one embodiment, a plurality of stem operators project into the access ports without opening the check valves therein when the test connector is installed in position on the control valve device. A handle is provided to effect rotation of an eccentric shaft on which the stem operators are connected to unseat the check valves and thereby access air at the respective access ports when it is desired to initiate testing following installation of the test connector. In an alternate embodiment, a plurality of test probes pivotally mounted on the test connector body enter the access ports and unseat the check valves in the course of installing the test connector in position on the control valve. In both embodiments, the stem operators/test probes are self-aligning to facilitate installation of the test connector.

    摘要: A broaching machine for cutting keyways in a bore of a piece part. There is a stationary bed plate on which is slidably mounted a moveable vise which slides along the bed plate. The jaws of the moveable vise clamp the piece part which is to be machined. A broach holder lowers the broach through an upper fixed support which has upper broach guide means disposed therein. The broach then passes through the piece part and through a lower broach guide means positioned in the bed plate. A broach pulling unit receives the bottom of the broach and reciprocates the broach in an up and down vertical cutting operation. The broach is maintained in position and alignment by means of the upper and lower broach guide means which are disposed above and below the piece part. The upper and lower broach guide means are removable and replaceable after a predetermined amount of wear has occurred. The piece part is moved into the cutting teeth of the broach a predetermined amount to remove the material from the piece part in the keyway cutting operation. A single broach is thus capable of cutting various depth keyways by controlling the amount of movement of the vise along the bed plate.
