formecl elongatecl and used f01 purpos'es where one cf the packed patts moves relatiwaly to the other, as a piston rocl in its gland, ancl it is therefore necessary er desirable t0 provicle the pac-king With Ineans to resist wear 01' other; unclesirable results.
inciclent 130 such movement. My ob jcct is t0 provicle an elongatecl packing of th1S type inclucling coils of yielcling material, which are primarily responsible for the sealing 01' packing quality of the packing, anal other coils of less yielding material, which are aclaptecl to resist the wear 'o'f the'packing incident tofriction, in which the coils shall be formed and arranged so-that while 1 ;he packing shall be reaclily capable of flex1on it shall also be well adaptecl to withstand ehe wear zmcl tear incident to relative m0- tion hetween the parts packecl and particular1y the forces tending 130 1clisrupt 01 break clown the materials forming the same.
In the drawing, Figure 1 shows a piece of the elongated core Fiigure 2 shows the core having spiral coils of wear-resiscing material and coils of material more yielcling than that ofthe first coils W0uncl spirally aro-und the same;
Figure 3 shows the product of Figure 2 provided with a casing formed topartially surround the same while leaving exposed the coils thereof longitudinally olt the artiCle FiZgures 4: and 5 illustrate a method 0f manufacturing the acking, Figure 4 showing the condition of the material at two cliflerent stages in the method and F1gure 5 showing one of the pieces-produced by the severing operation; and
F igure5 6 und 7 show, respectively, the packing pieces illustrated in Figures 8 and 5 aftervulcanizing, und molded to rectangular form.
The core a may consist of any s1l1table flexible material but it is preferably a fabric sheet impregnated, coated, 01' otherwise I. E. MAS' treatebl Withm1b-ber anclthenlolled up frm one eclge t0- the other in a compact mass 01' roll (Figure l). A sheet is preferred for the core hecause it may he formecl readily into the clesirecl shapeancl when so fo'rmed ofiers uniform soliclity while still heing flexible. V
Having such a c0rel ind sicle by side und spirally arouncl the same the at-tenuaterl elements b ancl c, the element b being a wear-resmtmg mater1al anal the other a ma terial which ls relatively yielding in nature.
The wear-resisting materiell b is designed t0 assume the wear of and therefore be exposecl to the mo'ving one of the part-sto be packed, and so it may be composed of a wire as shown, the chief constituent of which I prefer shall be graphitebecause of its lubricating character. The material of the element c, which must be more 01' less yielding in character in order to obtain a good packiugeffect may he a fabric 01 layers of fabric impregnated, coated or made to a1- ternate with rubber. If element c is of such materi;1l ancl i1; is arrangecl, as shown, so:
that its edgesstand presented to the coils b,
it is well adap ted 130 yield to the latter in the fiexingof the packing.
If the packi ng elemen thus formed cohtains ruhber, as above sei: forth, and as is:
referrecl, it Will be best t0 vulcanize als the final step in its -manufacture und in vul- 1 canizing it.may be mololecl to some suitable form other than c1rcular 111'010SS sectmn, as square, 111 cross sect1o-n. The colls c which are relatively yielding serve in the stufling b0x 01 equivalenc t0 seal the joint between theparts eo be packe d, while the other coils Z) act to resi'st the wearing away of the packing. The C0ils 25 b-eing in the hast form of non-yielding material (as the wire menfioned), so that While they res-pond to ttrition they will 11013 responcl to other lateral displacement cf their molecules, a:ny kneading produced in the packlng as the result cf the rubbing thereof by one 0f the packed parts is localized, or less efiective 011 the rulobed surface as a whole than on each individual coil c, 'Whereby the surface exposed 130 such part has a more'enduring capacity than if lt Were composed throughout of more o1 less. yielding materizl. Where the co-ils b, are not only f0rmed f wire but' are lubrioating in natura, so that uny grip incident t0 rubbing is thereby greatly re- (luce, they protect the packing from 1;hsv
effects of the rubbing and 1educe the. i ntensity thereof, so that there is not only lass frictional wear but 1ess tendency to disrupt and disintegrate the matrials 0f the pack- 1ng.
Figure 3 shows the product of Figu1e 2 contained in a casing (Z which partially surrounds t-he structure including the core a and spiral windings Z) and c, leavin the windings expose'd longitudinally o1 the product. 'Ihe casing (l may be formed of a fabric 01' 1ayers 0f fabrie impregnated, coate 01 mde to alternate With rubber. The casing adheres to the c0re because of the Presence 013 rubber as a const-ittlent of the casing anal 0f the element c; it may be made t0 adhere in any other Way. Rubber being present in the artic1e thus produced, the same may be vulcanized and in the pro0ess oi vulcanizing be molded 110 any suitable shape, for instance 'that shown in Figure 6. Th'e acting face 0f the packing, that is the face which is presented to the moving part t0 be packed, is that face where the 'spiral windings Will be eXposed, as illustrated in Figure 6 I may take 2L plurality of flexible cores e, for instance like the core a, anal form a, cov ering around and adhering to them, as by spirally wrapping around them and side by side attenuated pieces f und g/ respectively similar t0 the pieces b und c already des'cribed and then wrapping asheet 0f suitable material, as fabric h impregnated c0ated or other-w1se treated with rubbe1, around the spi1"-a1 windings. On cutting the article thus produced in a plane indicatued by 5-5 in -Figure 4, i. e. between the 'two c0res, two packing members Will rt=sult; and 'the Casi11g of each (1:0 wit, the half of the fab-ric coating h appertaining to eaoh) of these Will expose at One side and longitudinally the Wear-resisting matiarial, but in section (whi'ch in f'aet is ultimately the conditin wvhich the 00115 of the eleinent b assume wh an th ey become worn 'away in bhe gland). Usuall'y the two= parts resulting after the s6verihg Will be vulczirxized, anc1 in fhe vu1 caniz-ing treatment they may be molded into any f01'm as that shown in Figu're 7 lt Will be best to subjectthe p-acking, in whatever f0rm 01 by whatever method it is made, t0 pressure, as in the mold when vulcanizing it, in order 110 compress the C011- stituent arts into acompact mass and so insure integrity ancl stability of structure.
It Will be understood that ehe result 0f this,
treatment in the case 0f the packing shown v inl*igure 5 will be to c1ose up the ch'annels existing a1; z between the core and the malgin'al portions of the casingsee Figu'r 7.
Having thus fully described my inventi0n, 'What 1 claim as new und desiret0 seeure by Letters Patent is:
l. A flexible unitary packing body includii1g coils arrangecl around a common -which said coils are wound consisting of a rolled-up sheet 0f yielding material.
4 A flexible elongt-ed packing body including coils arranged around -a common axis and side by side, the alternating coils beii1g 'coinposed of yielding sheet material and the remaining coils of less yieldin mat'erial, the edges of said sheet material ing presented 110 the latter coils.
1 5. A flexible elongated packi'ng body includihg coilsarranged. aro-und acommon axis and side by side, and a casing of yie1ding material adhering to said coi1s and exposing the sam'e exteriorly thereof longitudinally of said axis.
In testimon whereof I aflix my si natura.
