Title: Improvements in or relating to rivet and method of riveting
IPC: F16B19/12
Filed: 1943-08-17
Abstract: 567,664. Riveting. JAKOSKY, J. J. Aug. 17, 1943, No. 13387. [Class 83 (iv)] [Also in Group XXV] Plates &c. are riveted together by means of hollow closed-ended rivets that are expanded by hydraulic pressure to fit closely the holes in the plates and to form a head on the projecting end. The rivet may have a relatively small bore 2, Fig. 1a, leading into a chamber 4 which, after expansion, takes the form indicated by the dotted line 8<1>. To facilitate the formation of the head, the end of the rivet may be formed as at 9, Fig. 1b. Other forms of rivet are illustrated. A plain tubular rivet may have the open end turned in to retain a separate closure plate inserted in the rivet and this plate may take forms corresponding to the ends in Figs. 1a and 1b. A rivet that may be stamped from sheet material has three inwardly projecting ribs 10, Fig. 3a, these facilitate expansion to form a head as well as provide metal therefor. The riveting is best performed by introducing a predetermined quantity of liquid under pressure, for example, by a tool comprising a cylinder 14 closed by a nozzle 24, that is changed according to the rivets to be expanded and contains a cylindrical cavity 25 having the required predetermined volume. The nipple 26 for engaging the rivet may be screw-threaded when pressure against the structure to be riveted must be avoided. The piston 15 is hollow and contains an auxiliary piston 21 to co-operate with the cylinder 25. A collar 191 provides for loading by a spring 22 of such strength that the piston moves as a whole till the desired working pressure is reached, after which the piston 21 advances compressing the spring and displacing the required quantity of liquid from the cylinder 25. The liquid may be oil, but a liquid that will set within and reinforce the rivet may be employed such as grouting made from portland cement or plaster of paris, or molten sulphur, solder, tin, &c., may be employed. When using magnesium or magnesium alloy, the expansion should take place at a temperature of from 300‹ to 500‹ F., and for this purpose the nozzle is replaced by a nozzle electrically heated at 35, Fig. 7. The nozzle is surrounded by heat-insulating material 36 that also surrounds the end of the cylinder 14. For occasional work, as for securing rivets in undercut holes 39, Fig. 8, to receive an article 43, a tool 40 may be employed. The end 41 is entered into the hole in the rivet filled with liquid and is then driven in up to the shoulder 42 by means of a rubber mallet. Other liquids may be employed, such as various plastic materials, resin, and pitch.

[Also in Divisions G1 and H1] In a radio transmitter installation a feeder 12 connects, and is matched to, a transmitter 11, Fig. 1, and a tuning arrangement 13 of an aerial 14, which has a length not exceeding an eighth of the operating wavelength. The said tuning arrangement comprises a reflectometer 115, a transformer 16 having primary and secondary windings 15, 18 upon an R.F. magnetic core 17, a variable inductor 19 paralleled across the secondary winding 18, and an R.F. current meter 21 and a variable inductor 20 in series between the secondary winding 18 and the aerial. The core 17 of the transformer 16 is formed by opposing pairs of C-shaped ferrite members, the ends of their limbs being separated by spacers (Figs. 7, 8, not shown). Each inductor 19, 20 comprises two windings on hollow cylindrical insulating formers, one former being slidable within the other to provide a continuous variation of inductance (Figs. 9, 10, not shown). Discrete changes of inductance are obtained by suitably interconnecting the ends and centres of the coils of an inductor (Figs. 5(a), 5(b), not shown). The reflectometer 115 is of a bridge type, indications being given by a D.C. meter 22 supplied from a diode 52. A ganged pair of switches 50, 53 enables measurement to be made of either the power directed to the aerial, or the power reflected from the aerial. The components of the tuning arrangement are mounted upon a chassis 45 which is contained within a waterproof metal container (40), Fig. 6 (not shown). A sheet metal member of the chassis serves to support the two inductors and provide screening. As described, the transmitter (Fig. 12, not shown) is suitable for operation either in the band 285 to 315kHz or, alternatively, in the band 200 to 400 kHz.
