IPC: G01N3/06
Filed: 1936-08-08
Abstract: 476,399. Testing physical qualities of materials. LEAN, R. J., and QUINNEY, H. Aug. 8, 1936, No. 21892. Addition to 448,130. [Class 106 (ii)] The parent invention in which a spring stressed to an extent more than necessary to fracture a specimen is connected to one end of the latter, the other end being relatively fixed, and the spring released by the amplitude of vibration of the spring after fracture of the specimen being recorded, is provided with a modified construction of recording- mechanism. A spring 24 carries a movable holder 41. A second holder 42 is secured to a resilient member 200 rigidly attached to a frame member 22. The spring 24 is deflected upwards by means as in the parent Specification and a test piece 69 is inserted into the holders. Trip means are operated to release the spring and the specimen is subjected to a sudden stress which is transmitted through the specimen to the resilient member 200. The strain in the member 200 and the corresponding movement of spring 24 are recorded. Holders. The ball 64 is clamped to one end of the test piece 69 by a plug 73 and washer 210 being located axially by a conical point 68. It is then introduced into a cup 60 through an opening 211 and a reinforcing ring 212 brought down and screwed home. A milled head 214 and rubber washer 216 prevent rebound when the specimen breaks. The lower holder which.is similar and screws into a support 47 may be adjusted to accommodate different length specimens. Side walls 48 and ledges 49 on the support 47, together with screw pillars 219, 220, serve to clamp the holder of the spring 24. The C-shaped member 200 is secured by bolts 222 and a conical spindle 224 to the frame 22. The upper holder 42 is screwed into the member 200. Recording. The upper ends of pillars 219, 220 are pressed against rollers 227 carried on the spring 200 by rollers 228 supported from the frame 22 by resilient arms 229. A drum 231 to which a sheet of celluloid is clamped is mounted as roller bearings on the lower end of spindle 224. Each side of the lower part of spring 220 has secured to it a plate spring 236 carrying a diamond point bearing on the celluloid strip and when spring is deflected a line is traced proportional to stress. At the same time when the spring 24 is deflected a roller 240 carried by pillars 219 and engaged by a spring-pressed cam plate 238 on the drum rotates it an amount proportional to the sum of the deflection of spring 200, and the extension of the specimen. Since the strain in spring 220 is marked on the strip for each degree of movement of spring 24, the actual extension can be calculated. In a modification, the drum is mounted on the lower limb of spring 220 and the diamond point carried by the fixed part. This gives the extension of the test piece directly.

Filed: 1944-11-15
Abstract: 583,671. Uniting by fusion. LINDE AIR PRODUCTS CO. Nov. 15, 1944, No. 22549. Convention date, Dec. 23, 1943. [Class 83 (iv)] A guide and contact jaw assembly for an electric welding rod comprises a body member with an elongated cavity which is open at one side and has secured therein a stationary current - conducting jaw, a movable current conducting jaw within the cavity, a flexible current conductor with one end secured to the body and the other to the movable jaw, and a leaf spring in the cavity between the movable jaw and the cavity closing means, the end portions of the spring bearing against the closing means and a rounded central portion bearing against the movable jaw. The relatively long contact jaws thus bear uniformly throughout their length against the welding rod and increase the area of contact therebetween and thus avoid arcing at points of imperfect contact, and ensuring uniform wear on the contacting surfaces. The jaws are composed of hardened beryllium-copper alloy. The coupling member C, which is secured to the welding head and carries the current supply cables comprises a hardened copper stem 10 and a collar 12 prodided respectively with passages 13, 14 for the rod R and a body with an elongated laterally-open cavity K in the end of which is secured by a screw 16 a stationary current conducting jaw Js provided with a guide groove 31 and bevelled ends 30 to facilitate entry of the rod. The movable jaw Jm with a flat surface is loosely suspended in the cavity by a flat copper braid conductor P secured by a screw 18 in a recess 35 in the stem, the conductor being secured to the jaw at 17 below its centre so that the jaw floats more freely within the assembly in operation and opens more readily when a rod is inserted through the jaw, regardless of the diameter thereof. The cavity is closed by a cylindrical case H of thermally and electrically insulating material which also prevents the entry of foreign material into the jaws. Between the' case and a strip 20 of, thermal insulation in contact with the conductor is mounted one or a number of arcuate leaf springs S of flat crosssection, the outer end portions of which bear against the case H and the central curved portion bears against the strip so that the resultant of the biassing forces passes substantially through the centre of gravity of the jaw so as to distribute the bearing pressure uniformly over the contacting surfaces. The number of springs used varies with the diameter 3 of the welding rod.
