Abstract: 746,228. Circlips. GENERAL MOTORS CORPORATION. Feb. 1, 1954 [Feb. 11, 1953], No. 2966/54. Class 89 (2). [Also in Group XXIV] Rattle of an idling gear 6 on its splined mounting on a shaft 4 is prevented by a spring ring 20 in a groove 18 in the gear, and having end and intermediate lugs 26, 24 engaging the shaft grooves, and an unstressed diameter (shown dotted) slightly less than that of the shaft so that in its installed position it grips the shaft radially, and at its smooth outer periphery compresses a rubber strip 22 lining the base of the groove 18. The ring 20 has axial undulations wider than the groove 18 to grip the latter axially. Alternate splines 16 in the gear may be shorter than the effective splines 14 to bear on wide lands between the shaft grooves.

Jan. 30, 1934, No. 3147. Convention date, Jan. 31, 1933. [Class 126.] A stove comprising a fuel reservoir 10, a conduit or tunnel 17 of refractory material open or perforated at the bottom and extending between two opposite walls of the reservoir to open at one or both ends into conduits or recuperators or into discharge conduits connected to an outlet flue has at its lower part a funnel formed by two inclined planes 13, 14 extended downwardly by two other inclined planes 15, 15<a>, having at their base cinder discharge means 16. The tunnel 17 forms the combustion chamber. Air passes by way of an inlet conduit 21 at the back of the stove to the top of the fuel reservoir where it mixes with distillation gases and the mixture passes by way of a conduit 23 at the front of the stove to the open front end of the tunnel where it ignites on contact with hot combustion gases. The combustion products leave the tunnel by way of conduits 18 and 19, the conduit 18 being adjacent to and serving to heat the mixture of air and distillation gases in the conduit 23. In a modified form the tunnel is open at both ends and the combustion products pass to the flue by way of a conduit at the back of the stove adjacent to and serving to heat the incoming air in the conduit 21.

The embodiment shown is for use on the leg of a patient and comprises a thigh-engaging member 3 which has a U-shaped metal skeleton covered by a padded sheath (5), Fig. 1 (not shown). The member 3 may be varied in size by bending the metal skeleton. The sheath (5) forms two straps 6, 7; the strap 7, and a strip 8 attached to the strap 6 carry cooperating "touch and close" tapes (11) and (9). The side members are made up to the required lengths from rods, and arms 14, 15 of a generally U-shaped bridging piece 4. Thus, for example, the side member 1 consists of the arm 14 which is telescopically received in the hollow end of a rod (16) having an extension pin (21) received by the hollow end of a rod 18; the extension pin (23) of the rod 18 is received by a stub 12 swivellably mounted on the member 3.

Abstract: 783,297. Stopping shafts in predetermined positions. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 2, 1956 [Feb. 8, 1955], No. 3708/55. Class 80 (2). A shaft 18, which operates a valve for taking samples of liquids from a number of pipes, for testing, is adapted to be stopped in any one of fifty-four positions by a primary shaft 16, driven by a motor-driven shaft 10 through a lost-motion claw-coupling 17 and driving the positioned shaft 18 through a non-slip reducing- gear 20. The primary shaft 16 is capable of arrest in either of two positions spaced 180 degrees apart, corresponding to the set positions of the shaft 18, by a detent comprising two axially or radially spring-pressed rollers 30 engageable in V-notches in a fixed plate 25, or cylinder, and the lost-motion coupling 17 permits the detent springs to advance the shafts 16, 18 ahead of the driving-shaft 10 as the located position is approached.

Title: Manufacture of spiral metal pipe
IPC: B21C37/12
Filed: 1928-02-07
Abstract: 308,419. Dehn, F. B., (California Corrugated Culvert Co.). Feb. 7, 1928. Pipes.-Helical metal pipes are made by coiling a sheet of metal into tubular form, the edges being crowded together to form a lapped seam, and then fusing the edges to form a joint of greater thickness than that of the sheet. The edges may be overlapped to form a seam of double thickness, the seam being completed by fusing along the edges of one convolution. The sheet 10, which is guided by rollers 13, is fed by rolls 11 at an angle beneath rolls 19, 20 and over a roll 18 to coil the strip into tube form. The roll 18 is driven from the main shaft and drives the rolls 19, 20 by gearing 27 and universally jointed shafts 28. These rolls are driven at a greater speed than that of the feed rolls, so as to provide a slight slip between them and the surface of the sheet so as to avoid excessive friction between the edge 10<b> of the sheet and the guide rollers and reduce friction caused by the endwise slip of the sheet off the roll 18. The rolls 18-20 are mounted in a base pivoted at 36 so as to adjust the angle of feed according to the diameter of pipe or width of strip. The roll 18 is mounted in bearings in the yoke 15 and also in a bracket 22 positioned so as to clear the upwardly curving edge 10<a> of the sheet. The rolls 19, 20 are mounted in bearings in beams 23, 24 fixed to the yokes 16, 17, the beam 24 being adjustable by screws 25 to suit the diameter of the tube. The seam is fusion welded by a burner 38 or electric arc, the edges being crowded together to tend to cause them to overlap and so provide metal to form a seam 39 of greater thickness than that of the sheet and thus avoiding the use of additional welding material, by offsetting the tube by passing it through a guide 29 angularly adjusted by a screw 37 along a curved track 35 centered at 36. The guide is provided with rollers 31, mounted in swivel brackets 32, one of which is adjustable by a screw 34 to suit the diameter of the tube. The angle of feed may also be varied by swinging the feed mechanism 11 with respect to the bending mechanism. The machine. may also form a tube with an overlapped seam, Fig. 7, welding being then effected at 40. The bending rolls 19, 20 may be replaced by a series of spindles 41, 42, Fig. 8, driven by worm gear 45, 46 from shafts 47, 48 and having button-shaped heads 43, 44, to assist in feeding the sheet forward. In a further modification, the bending rollers are replaced by a series of pairs of rolls 51, Fig. 9, co-operating with a series of idle rolls 63. The pairs of rolls 51 are mounted in swivelling-sleeves 49 which are provided with arms 56 connected together by a rod 57. The rolls are driven by bevel gear 52 from shafts connected by gears 54, and operated by bevel gear 55 from the main drive. The beam 24<1> is pivoted at 58 and is adjustable by lever and link mechanism 59 operated by a screw 61. The rolls 63 are carried in brackets 64 swivelling at 65 and connected together by a bar 67.
