Title: Improvements in or relating to the manufacture of hollow fluid conducting members
IPC: B21D53/04
Filed: 1956-03-09
Abstract: 784,484. Making pipes and heat exchangers, casting composite ingots, stamping. REVERE COPPER & BRASS, Inc. March 9, 1956 [March 9, 1955; June 29, 1955], No. 7529/56. Classes 83 (1), 83 (2) and 83 (4). A method of making metal strip having one or more longitudinal slits which can be expanded by fluid-pressure to form tubular passages, e.g. for heat-exchangers, comprises casting a billet around one or more rods of friable material capable of being crushed to a weld-preventing powder and rolling the billet to the required thickness thereby crushing the rods and forming slits filled with the weldpreventing material. The rods 3 are preferably of rectangular-section but could be of round, oval or tubular form and are made of graphite, soapstone, china clay, magnesia or alumina. After rolling, the sheets are clamped between die plates such as 59, 61, Fig. 16, and the slits 7 expanded by fluid-pressure to form such shapes as those shown in Figs. 7 to 10. Before the expansion the ends of each of the slits is opened out mechanically, a plug 41, Fig. 14, is inserted at one end and a nozzle 35 at the other. The billet may contain several rows of rods to give sheets with slits arranged as shown in Figs. 24, 26 or 31, which may be expanded as shown in Figs. 25, 27, 32, 51, 54. The sheets may be slit longitudinally to form single tubes, or a billet may be cast around a single rod and the tubes thus formed, after expansion, may have marginal portions by which it can be fixed to a surface, e.g. Figs. 46 and 47. In addition the walls of the tube may be formed with corrugations, Fig. 49. The sheets may be of aluminium, zinc, copper, brass, bronze, nickel silver, stainless steel or carbon steel. Casting. The billets are cast in a mould comprising a vertical chamber, Figs. 34, 36, with side walls 77 engaged by water-cooled castings 87, 89, end walls 79 formed by water-cooled castings 91, and a bottom 81 formed by a watercooled casting 93, the elements being secured together by bolts. The rod inserts are held in position in the mould by upper refractory horizontal plates 111, 113, preferably of graphite and by lower refractory plates 127, 129 which clamp the rods to prevent them from rising due to buoyancy when the molten metal is poured through an upper pouring-box 121. In a modification, the inserts are built up from a number of interengaging sections 285, Fig. 59, threaded on rods or wires 279 which are secured within the mould. Alternatively, the billets may be formed by continuous casting.

Abstract: 362,799. Gear-cutting. MUYLDER, E. VAN, 25, Rue Louis de Coninck, Berchem, Antwerp, Belgium. March 12, 1931, No. 7630. Convention date, March 24, 1930. [Class 83 (iii).] In a machine for generating toothed gears, a shaft 7 which is oscillated from a crank disc 2 through links 4, 6, is connected through a lever 8 and links 10 to a slide 12 carrying flexible bands passing over a master cylinder 15 on a spindle 16 carrying the blank 17. A further lever 18 on the shaft 7 is connected through a telescopic link 20 to a slide 22 provided with an adjustable slide 24 carrying a cutting or grinding tool 23 driven by a pulley 27. Thus if the pivots 9, 19 are at equal distances from the shaft 7 and the links 10, 20 are of equal length, the tangential movement of the cutter slide will be the same as that of the slide 12 and the rotation of the blank will be in unison with this movement so that the cutter will generate teeth having the same base circle diameter as the cylinder 15. For cutting smaller or larger gears from the same master cylinder the pivot 19 is adjusted to or from the shaft 7 and the link 20 is proportionately adjusted by means of an inclined slideway 21a. The flexible band device may be replaced by equivalent rolling mechanism. By adjusting the location of the pivots 19, 21 from their theoretical positions teeth differing slightly from the theoretical profile may be cut.

Abstract: 438,718. Cigarette - making machines. ARNOLD, C., 12, Southampton Buildings, Chancery Lane, London.-(Davidson, G.; R.F.D. No. 1, Box 62D, Portsmouth, Virginia, U.S.A.) March 19, 1934, No. 8556. [Class 130] Cigarettes with inserted mouthpiece plugs are made in continuous-rod form by cutting through the advancing tobacco rod, without severing the paper wrapper underneath, by means of cutters passing through apertures in a belt, band, or drum, between which and the paper wrapper the tobacco rod is located, the cut-out sections of tobacco being afterwards removed and replaced by the plugs. The Figure shows apparatus for cutting the gaps and inserting the plugs, the cutters comprising pairs of blades 25 secured at spaced intervals around a drum c by means of wedge blocks 23 and adjustable slides 26. As the drum is rotated, the cutters are pressed radially through the tobacco rod as it passes over a spring- supported anvil 28 underneath the drum, the absence of sidewise movement of the blades being sufficient to prevent severing the paper wrapper. The cutters operate through openings 5 spaced along an endless feed band e passing round an idler drum 6 and the plug-inserting drum 7. As the tobacco rod, covered by the band e, passes from the drum c to the drum 7, the cut-out sections of tobacco, exposed by the openings 5, are removed by suction operating in a suction head 31. The plugs 63, previously made and cut to size, are advanced in a stream at right angles to the tobacco rod and pass over a face plate 65 and between a pair of wheels 67, which are rotated by a motor so as to force the plugs between pairs of fingers 43, 51 pivoted at 44, 52 around the drum 7. These fingers are operated by cams formed around the drum so that the fingers 43 move the plugs circumferentially, and the fingers 51 push them radially into the gaps in the tobacco rod, as they reach the bottom of the drum. The paper wrapper is then turned over and secured, and the cigarette rod cut at the middle of the tobacco and plug sections. The cutter and plug-inserting drums may be mounted separate from, and between, the drums 6, 7 ; or the drum 6 may be replaced by a series of guide rollers, which may then be arranged so that the band e grips the tobacco rod before it reaches the cutter drum. Again, the tobacco rod, instead of being fed in a straight path under the cutters &c. may be guided in a curved path around a part of a drum which encloses both the cutter and plug-inserting drums.

The transverse members T of the carriage are connected to the parts 2 of the casings and the parts 2, 3 are connected by a tongue 4 so as to enclose the mechanism as indicated at the left hand of the machine in Fig. 1. Associated with this casing are a number of parts, viz.: a key 7 for carriage release, key 8 for left margin stop, knob 9 and scale 10 for line-spacing, knob 11 for platen release, and a spacing-lever 5 extends through a slot in the casing. Similar controls 15, 16, 17 are provided in connection with the right-hand casing. The platen 30 is mounted between the casings so as to be readily disconnectible. It is normally rotated by a ratchet mechanism operated by the lever 5, and acting through a clutch 33, 34 which drives a hollow shaft 31 mounted in ball bearings 32. A similar shaft 31 is mounted in the right-hand casing and each shaft 31 is integral with a disc 36 provided with a diametrical projection 37, Fig. 3 (not shown), which engages a similarly shaped groove at each end of the roller 30. The roller can be withdrawn laterally when a shaft 38, which normally connects the two hollow shafts 31, is withdrawn by means of a knob 39. The shafts 31 may be operated by hand wheels 22, 23, or can be set in position by a handle 13 acting through gears 44, 45.
