A pin for injecting a grout material comprising an upper structure (I) into which an upper half portion (1′) wherein a screw thread (2) and a lengthwise hole (3) are formed, a packing (4), a washer (5) and a knock pin (11) for knocking a grout pin (10) are inserted, and a lower structure (II) into which a lower half portion (1″), both tongued pieces (7′, 7″) of a slit wherein said slit (7) and a knurling portion (8) are formed and in the space formed by both tongued pieces (7′, 7″), through the lengthwise hole (3) of said upper structure, the grout pin and the knock pin for knocking said grout pin are inserted.
A tire fill valve having pressure relief and tire fill fluid gas flow limiting characteristics for use in filling tires to a predetermined pressure form a large flow capacity gas source delivering fill gas at a substantially greater pressure. Gases utilized typically are air or nitrogen. The valve of the invention is wheel mounted intermediate the gas pressurizing source and the tire gas valve inlet. Tire fill gas from a high pressure high capacity source passes through a flow limiting orifice having a positive closure or shutoff member and passes through a pressure sensitive chamber as it enters the tire.
A pneumatic control apparatus and method controls gas pressure inside a tire mounted on a wheel which rotates about the centerline of an axle. A bleeder valve is mounted on a body coaxially aligned with the axle centerline and is in fluid connection with a pneumatic fitting on the tire. The bleeder valve allows gas inside the tire to be relieved to the atmosphere when the gas is above a set pressure. The coaxial alignment of the bleeder valve with the axle centerline permits the bleeder valve to relieve gas pressure unaffected by centrifugal forces.
An adaptor for injecting glue under high pressure into a joint to includes a shank portion with a self tapping external thread tapering from a connecting portion having an internal connecting thread for attachment to a zerk and radially outward wings, forming fingerpieces by which the shank portion can be rotated. An internal glue passageway extends completely through the adapter. A restorer's kit includes a supply of adapters, zerks, a high pressure lever action hydraulic gun for glue, a flexible high pressure connecting hose and zerk coupling, a veneer needle and a supply of dowel form wooden plugs.
The present locking mechanism for rotatable fastener functions to reliably and inexpensively secure a rotatable fastener in place once it is seated. This is accomplished by the formation of an aperture into the body of the rotatable fastener in a lengthwise direction coaxial with the axis of the cylindrical shaped rotatable fastener. A second aperture is formed in the body of the rotatable fastener perpendicular to the first aperture and intersecting same. A locking pin is placed in the second aperture such that one end of the locking pin is flush with the surface of the body of the rotatable fastener, non-interfering with the operation of the threads formed on the exterior surface of the body of the rotatable fastener. A second end of the locking pin protrudes into the first aperture. A locking post is placed in the first aperture, located above the locking pin and accessible via the open end of the first aperture in the head of the rotatable fastener. A craftsperson uses a tool to force the locking post down into the first aperture to thereby engage the protruding end of the locking pin, forcing the locking pin to move in the second aperture away from the first aperture. The locking pin is thereby driven into the wall of the cylindrical shaped aperture into which the rotatable fastener is threaded and prevents the further rotation of the rotatable fastener in either direction.
A sealable fastener for insertion into a fastener opening bore in a receiving structure includes a fastener shank including a shank first end having a shank first end wall and a shank second end having a shank second end wall, a shank side wall extend between the shank first end wall and the shank second end wall and a circumferential channel recessed into the shank side wall; and a sealant delivery passageway having a passageway entry port in the shank first end and extending to a passageway exit port opening into the circumferential channel; so that a flowable sealant injected into the passageway entry port flows through the sealant delivery passageway and exits through the passageway exit port and flows into and around the circumferential channel, creating a circumferential seal between the fastener shank and the fastener opening in the receiving structure.
A sealable fastener for insertion into an fastener opening in a receiving structure includes a fastener shank including a shank first end having a shank first end wall and a shank second end having a shank second end wall, a shank side wall extending between the shank first end wall and the shank second end wall and a circumferential channel recessed into the shank side wall; and a sealant delivery passageway having a delivery passageway entry port in the shank second end and extending to a delivery passageway exit port opening into the circumferential channel; so that a flowable sealant placed in the fastener opening is drivable into the delivery passageway entry port as the fastener shank is inserted into the fastener opening, so that the sealant flows through the sealant delivery passageway and exits through the delivery passageway exit port and flows into and around the circumferential channel, creating a circumferential seal between the fastener shank and the fastener opening in the receiving structure.
In a fastening device of the kind described in Specification 524,297 for securing together articles having registering apertures through which the device is passed, and comprising a tubular body 1 with a head 5 for abutment against one article, and balls 4 which can be projected radially to abut against the other article to retain the device in place, or allowed to collapse inwards to release the device under control of an axially movable member 6 within body 1, the body 1 has a bore of uniform diameter and the member 6 is positively moved between its two positions, in each of which it is retained by spring-loaded radial catches 12. As shown, the tubular bore 2 is closed at the left-hand end to exclude dust &c. the balls 4 are held captive in radial apertures 3 with reduced mouths, the rod 6 has a reduced end 7 which in the position shown allows the balls to move inwards, the rod 6 when moved to the left moving the balls outwards to project from the surface of body 1, and radial catches 12 surrounded by a spiral spring 15 engage in one or other of two grooves 9, 10 in the rod. The spring is covered by a sleeve forming the head 5. The rod is moved by a ring 8 which is slidably engaged in a slot in the end of body 1 so that rotating ring 8 rotates the whole device, if necessary to loosen it in the apertures. The invention is also applicable to the devices of similar type described in Specifications 554,307 and 555,041.
At least two components 1, 2 are releasably secured together by a bolt or stud 3 having a screw-threaded portion 5, 6 on at least one end to receive a nut 4 and having a blind bore 7 extending axially inwards from one end, a piston 8 extending in the bore 7 from its open end towards but stopping short of the blind end, the piston 8 being secured to the bolt 3 adjacent the open end of the bore, means being provided to admit pressure fluid to the blind end of the bore to pre-stress the bolt while the nut 4 is tightened, so that the joint remains stressed when the fluid pressure is released. As shown, a bore 10 through the piston 8 forms the admission means for pressure fluid. The stud or bolt 3 may be integral with one of the components 2. After completion of the joint, the piston 8 may be removed and the blind bore 7 plugged by a slightly tapered screw-threaded plug (not shown) which expands the upper part of the bolt radially to lock the nut 4.
In one embodiment of this bung, which comprises a compressible sleeve (6) which swells in the orifice (1) to be obturated under the effect of the tightening of the screw (7), there is created a rotational immobilization of the bung in the orifice (1) before tightening, for example by having provided elliptical cross-sections of bung and orifice.
