摘要： 167,926. Smith, A. J. D., and Smith, A. D. June 19, 1920, Buttons, apparatus for making.-A button is made from a hemispherical metal stamping 1, Fig. 2, having a fabric covering 2 the edges of which are temporarily held by a cardboard disc 4. The edges of the blank placed in a die 5, Fig. 5, are bent or rolled together by plungers 6 so that they overlap, clipping the fabric cover 2 and forming a button, Figs. 4 and 7, circular in section and tapering to a point at each end. The button is attached by sewing through the fabric covering or a projecting tab 9 of fabric or other material clipped between the overlapping edges of the stamping.

摘要： 1,055,454. Joint-making packing; pipe coupling. D. SMITH. May 11, 1964, No. 19509/64. Headings F2B and F2G. A gasket 9 for a pipe coupling comprises a corrugated sheet metal ring having end portions 24 parallel to the axis of the ring, the corrugations comprising at least two ridges 25 extending radially outwardly beyond the end portions and at least one V-section groove 26 separating the ridges and lying radially inwardly of them but radially outwardly of a cylindrical plane containing the end portions. The gasket is housed in notches 4 in the pipe flanges 3 with its ends 24 tightly and sealingly engaged in slots 5 in the flanges. The slots 5 are preferably tapered to provide a wedging action with the rectangular section ends 24 which sealingly engages the walls 30 and 32 of the slot. Alternatively, the ends 24 may be tapered and the walls 30 and 32 made parallel to each other. Preferably at least the ends 24 of the gasket are coated with a soft amalgam. In a modification, Fig. 6, a spreader in the form of a split ring 6 which may be corrugated, Fig. 8 (not shown), and has pressure equalizing holes 8 therein is inserted between the ends 24. In a further modification, Fig. 10, the gasket is surrounded by a split metal back-up ring 40 that engages recesses in the flanges 3 and has two circumferentially opposite slots 41 therein to facilitate removal of the ring 40 complete with the gasket 9 and spreader 6 from the flanges 3. The pipes are coupled together by a clamp 14 which it is stated may be of the bi-metallic type described in Specification 805,676.

摘要： 900,574. Fishing rod rests. SMITH, A. J. D. Dec. 30, 1960 [Feb. 9, 1960], No. 4536/60. Class 48. A fishing rod rest comprises two upper rods 11, 12 secured to a lower rod 10 by a clamp 13 so that the rod 12 is angularly adjustable relative to the rod 11. The fishing rod is supported by a full ring 17 or a C-ring at the top of the rod 12 and a fork 18 at the top of the rod 11. The lower end of the lower rod 10 is either pushed into the ground or it may be secured to a tree or to the side of a boat by a clip. The clamp 13 comprises a pair of check plates 13a and a bolt and wing nut 14. An eye at the end of the rod 12 is located by a second bolt and wing nut 15.

摘要： 876,498. Linkwork. POWRIE, N. C., and ROGAN, D. S. Feb. 20, 1959 [Feb. 24, 1958; July 8, 1958], No. 6016/59. Class 80 (3). [Also in Group XXXIV] For applying a thrust with a variable mechanical advantage to a pitman 24, for operating the brakes of a motor vehicle, a pendant lever 10, pivoted at 12, has an effort arm 16 and working arm 18 formed with the cam faces 20, 21, 22, engaging a roller follower 26 attached to the pitman, so that when the effort arm 16 is rotated anti-clockwise against reaction of a spring 14, the lift of the cam nose 22 first causes the pitman to move with a low mechanical advantage to take up slack in the system, after which the slope of the face 20 provides a high mechanical advantage to provide the braking effort. Further movement of the pedal reduces the mechanical advantage again and allows the pedal to be pumped if fluid in an associated hydraulic system is low.

摘要： 805,676. Pipe joints. SMITH, D. Nov. 12, 1956 [Jan. 11, 1956], No. 34480/56. Class 99(1). [Also in Groups XVII and XXV] A clamping ring for flanged pipes, pipe fittings or bottle closures comprises a surrounding metal band 6 having lugs 7 which are curled inwards and contain a curled piece of metal 10 of higher coefficient of expansion to form a bimetallic element the inner free legs of which are contained in an indentation 8 in the band which restricts circumferential movement and acts as a stop for limiting tightening movement when the inner faces of the curled lugs press against pipe flanges 24, 25 with a force component coaxial with the coupling. The band can be formed in a power press, the lugs 7 then pressed into a U-shape, the inner metallic parts 10 inserted and finally the press shaping the bimetallic elements to their finished form. To strengthen the indentations 8, extensions 12 are formed towards the edges of the band which stiffen it at points opposite the middle of the lugs. To draw the band edges together an end 13 is folded over outwardly and spot welded so that a slot end 14 contains a bolt 15 to which it is permanently attached by a cross head 16. The other end 20 of the band is welded to a socket 21 which contains a T-head 23 of the bolt. Specification 781,676 is referred to.

摘要： 624,821. Belt gearing. SMITH, O. D. July 10, 1947, No. 18219. [Class 80 (i)] In belt drives for machine tools of the type described in Specification 558,665 including a driving motor 21 and a countershaft 25, the motor and countershaft bearings 28 are mounted on a framework which is resiliently pivoted at 37 above the system supporting pillars 31, and spring-held to tension the final driven belt. The framework is formed by two spaced flanged side members 10, 11 rigidly connected by transverse members 13 carrying the mounting 18 for the motor, and the countershaft and pivot bearings 28, 41 are detachably secured to the inner faces of the side members. The motor is adjustably mounted in slots in member 18 to tension the driving belt 23. The spring support comprises an adjustable piston 45 pivoted on one of the bars 13 and mounted between compression springs 47, 48 in a cylinder 46 supported through pivoted links 51 ...54 on the pillars 31. The machine tool is driven from a stepped pulley 26 on the countershaft, and when the belt is to be moved it is first slackened by turning links 52 through 180 degrees about shaft 53 by means of a handle (not shown) thereon, thus tilting the framework 10, 11 about its pivot 37. The system is adjustable on the supporting pillars by means of split sleeves 34.

摘要： 565,377. Combustion chambers. WESLAKE, H., and SMITH, O. D. March 30, 1943, No. 5120. [Class 7 (iii)] An internal-combustion engine, particularly of Diesel type, has a combustion chamber 11, Fig. 2, formed jointly by a pocket 13 in the piston crown and a pocket 11 in the cylinder head, over the cylinder, the remainder of the piston being.arranged to approach as closely as possible to a flat surface on the cylinder head, the exhaust port being arranged in the depression and the inlet port in the flat part of the head. The combustion chamber is located to one side of the head, Fig. 1, and the pocket 11 extends somewhat beyond the cylinder wall as shown at 16. The volumes of the two pockets are approximately equal so that the piston pocket which is bounded in Fig. 1 by the radial lines 20, 21 at 135 degrees and by arcs 18, 19 and 17 is slightly deeper than the head pocket. The central fuel nozzle preferably directs fan-like spray in a plane 28 separating the two parts of the combustion space. Alternatively, in a modification, the nozzle may be arranged near the bottom of the pocket 11 and directs its spray in a downwardly inclined direction. Specification 565,394 is referred to.

摘要： In a linkage mechanism (8) formed and arranged for mounting a furrow press (10) or the like onto the front of a tractor (1) or the like, the linkage mechanism (8) comprises an elongate support member (24) having suspended thereon at a distal end thereof a furrow press (10). The linkage mechanism (8) is formed and arranged with drive rams (38)(Fig.4) for varying the amount of yaw of the elongate support member (24) with respect to the longitudinal axis (39) of the tractor (1). The linkage mechanism (8) is arranged such that the furrow press (10) may be moved in a horizontal arcuate pathway ('B') from a first position on one side of the tractor (1) to a second position on the other side of the tractor (1) with the furrow press (10) remaining substantially on the ground between the first and second positions.
