Title: Improvements in or relating to packing devices for fluid pressure apparatus
IPC: F16J15/56
Filed: 1949-05-04
Abstract: 662,083. Stuffing-boxes. AUTOMOTIVE PRODUCTS CO., Ltd., LEVITATION, Ltd., and THORNHILL, P. W. April 11, 1950. [May 4, 1949] No. 11943/49. Class 122(v). A scraper device for a reciprocating member extending into a liquid-containing chamber comprises a scraper ring of flexible and resilient material of such dimensions that there is clearance between it and the surface of the reciprocating member, and means operative during outward movement of the reciprocating member to deform the ring into engagement with the said surface. A plunger 15 reciprocates in a liquid-containing cylinder 10 .sealed by a packing 17 axially spaced from an inwardly projecting outer end flange 24 of the cylinder by a sleeve 25 having a part 26 of its inner surface adjacent the flange 24 of frusto-conical shape converging towards the flange, the remainder being cylindrical. Between the packing 17 and a flexible scraper ring 27 is housed a rigid operating ring 28. On the inward stroke of the plunger, the scraper ring lies clear thereof opposite the cylindrical part of the sleeve 25, the operating ring 28 having been lifted by inward projections 29 on it engaging the plunger 15. On outward movement of the plunger, the operating ring 28 carries the scraper ring 27 along the frusto-conical surface 26 so that it scrapes the plunger 15 and removes any liquid that has escaped past the packing 17. The liquid trapped by the scraper ring is stated to be carried back on the plunger during its inward stroke to the inner side of the packing 17 which is of the type offering a higher resistance to leakage in an outward direction than in an inward direction. In a modification the operating ring is integral with the scraper ring. In another modification the scraper ring comprises an inwardly-directed lip having an outer rim located at the cylinder end, the lip normally having clearance around the plunger 15 and being directly acted on by the operating ring to press it against the plunger during the outward stroke. In yet another modification the scraper ring is L-shaped in section and has a tapered cylindrical lip which is pressed into engagement with the plunger by a similar tapering surface on the operating ring. Specification 602,913 is referred to in the Provisional Specification.

Title: End-jointing of timber
IPC: B27B33/08
Filed: 1975-03-22
Abstract: 1471511 Joining timber WADKIN Ltd 15 March 1976 [22 March 1975] 12071/75 Heading B5L A method of joining pieces of timber comprises cutting arcuate grooves in the ends thereof, adjacent grooves being separated by arcuate fingers, and adhering together the pieces of timber with the fingers of each piece received in the grooves of the other. The grooves are preferably cut simultaneously in the two pieces of timber by placing the timber (shown, e.g. at position 12 in Fig. 1) in the path of cutter teeth on opposite sides of a rotary cutter disc 1, the cutter teeth on one face of which are at radial locations corresponding to spaces between adjacent cutting circles of teeth on the other face. The cutter has peripheral saw teeth 10 (and preferably also hogging teeth 11 disposed between the saw teeth) so that initial transverse movement of the cutter across the ends of aligned pieces of timber squares the ends preparatory to grooving. The grooving cutter teeth 9, as shown Fig. 3, are formed on a screw profile 7, screw means 6, 6a, Fig. 2, being provided for radial adjustment of the screw 7 so that the teeth 9 can be adjusted to the correct radial position after resharpening. A gauge 15 (shown dotted in Fig. 1) located by holes 16 in the cutter body is used to ensure correct adjustment of the cutter teeth 9. As shown, four grooving cutter units 3 are provided in diametrically arranged pairs on each face. In apparatus (Figs. 7, 8 not shown) for joining timber serially by the method of the invention the timber is clamped at the machining station and after transverse movement of the cutter to square the ends the trailing piece is advanced towards the cutter and the cutter simultaneously advanced by half the distance moved by the trailing piece so that the two ends are grooved simultaneously. After movement to remove the cutter, glue is applied to one or both ends of the timber and the trailing piece advanced to make the joint. Photoelectric sensors are used to sense and control feed of the timber to the machining station and to control the machine operations in dependence thereon. In an alternative embodiment of the cutter (not shown), the grooving cutter teeth are formed on a number of discs clamped together, a single tooth form being cut across the edges of the discs, which edges are suitably tapered to provide the required groove section.
