manner; lit includes also the method emprodu'ction of such a spring,
ployed in the .L't iscontemplated that the present spring f may have a. wide utility and beforrned to "various sizes and shapes according to the particular requirements of its intended use.
In the production 'of the -present spring millilito combine economy in entspring, employs two components which co-operate'in providing a desired tension over a prolonged period of hard usage; in' case of one component breakingdown, the other component will continue to operate satisfactorily, thereby eliminating the immediate necessity of a complete I replacement which may oitentiines be accomplished 4only with shutting down of the associated mechanisms with a consequent loss and' inconvenience. I, furthermore,l y contemplate the manufacture of the pres ent spring according to a method which is simple and economical, and which assures the vproductionv of a spring having uniform characteristics It is with objects such as fthese, -and also others which will hereinafter appear, that my invention is primarily concerned. vIt may best be understood from the specication following, taken n `'conjunction with the accompanying drawfing .wherein- Figure 1, which is aview partly in elevashows the outer l Spfririg component `formed into a coil around 4Q ateinporar' core, this being the initial step ifffx'vhich is ta en;
Fig, 2 shows the two s in assembled relation as t the' second step has been taken;
Fig. 3 is asimilar viewl showing .the completed spring removed from the heating device which is used in the perfomance ring components ey appear after of the second step' required 'ita'inanufactureyand i Figs. 4 and 5 represent two ldifferent lforms into which the spring maybe bent for service. g
rhe two components of my duplex spring are a coil A having windings which sur- 'round a longitudinallyextending core B,
each of these parts being formed preferably of suitable spring'wire. The eoilsor. windings are fitted i and in the accomplishinentA ot this end the followingv pro dive is suggested;
The outer/ wi Eris initially formed in coils oi' 'wine g forming corevCtsee Fig. l), and thereafter removed from the core. A length of the spring wire so formed into coils is lthen placed in suitable supports 6 in proximity.A
to a heater hereshown as a gas pipe Zfhaving burner openings 8. By the operation of an appropriate shut oft valve 9, the flame tightly upon the core,-
about a temporary vor at the burner openings maybe regulated.
This second step vin the spring manufacture will produce anA expansion of the coilsor windings suilicient for the insertion ofthe permanent core wire B in place of the fornr ing core C. This" core wire B which re mains permanently .in the spring assembly is of slightly larger diameter than the forming core-:perhaps/ one orA two gauge sizes larger. It is receivable centrally throufrh the windings of the/ outer coiledl wire when the same is in expanded condition under the influence or' heat. Viith the assembly of the core wire B within the windings ci the outer wire A, the duplex spring is allowed to cool down, whereupon the windings of the outer wire contract tightly upon the core so as to remain as sembled therewith permanently and, for all practical purposes, inseparably. An assembly of the two wires in this manner, however, will not result in any such binding as to interfere appreciably with the In the production of a duplex spring, ac-
cording to this invention, it is 'contemplate which are convenient ioo that the same will be niadeto any lengths` for handling-perhaps four or-five feet. After' the .outer windingsy valve of the kind set forth in-my Patent No.
1,24U, 4,6l, granted September 18, 1917. Y In such a capacity, it would have special advantage owing to the .marked tendency of .springs to break from time `to time on account of the great frequency of reciproca! tions which they Yare called upon to oppose. In such an environment, thepresent spring would be less likely to break because of its. duplexV character, the outer windings affording reinforcement to the inner core, so that eren if one of these lcomponents becomes inoperative, the other would continue to func-tion for :1n-indefinite period.
