i METALLIC PAcKINe.
Specification of Letters Patent. Patented J an. 17, 1911.
Application filedApril 15, 1910., Serial No. 555,619.
To all wkm it, may concern:
Be 1t known tliat I, WILLIAM M. BROOKE, a c1t1zen of the United States of America,
and a resident-of New York, county and ing a well-set permanent metallic packing,
State of New York, have invented certain new and useful Improvements in Metallic Packmg, of which the following is a specifi cation.
This invention has reference to improvements in metallic packing for stufling boxes and the like. V
It is the special object of my invention to produce-- metallic packing for steam and Water and of great efliciency in an ammonia atmosphere. Means are providedwithin the properly adjusted after they have performed the required services and will disappear consequent to heat, wear and absorption leaving,
the metallic body in the form of a solid permanent metallic packing.
In order to render poss ble a compact setting of the packing the metallic cores form- 'ing part of same are composed of single wire-like small metallic cords or threads of triangular cross section which allow of an easy and effective compression. In this shape these have the advantage of wedging closely toward one another without'crowding as is the case with round metallic wires. In making thesmall cords or threads of triangular cross section cores are produced ofa strong cross section which are not subject to the same objections as the many types of known fibrous metallic packings which are deficient because they do not wedge so well.
The novel packing is prevented from-blowing into the cylinder or out through the gland or disintegrating by being spirally wound in cable fashion. This completely interlocks the numerous cords or threads and from practical tests has vproven an efiicient method for holding the same in position.
The single cords or threads of triangular cross section are made of any suitable com position of metals which varies according to the liquid,.vapors or steam to. which the packing is subjected, different liquids and vapors having different effects upon difierent compositions. The metal or composition from which the cords aremade has prefer ably a fusion point above 600 F. and in "every case 1s softer than bronze or steel.
Practical and severe tests have proven its efficiency in filling scores on rods to be of a high standard The" packing is preferably provided with a cover for holding the entire mass intact.
Asbestos heretofore used is deficient because it hardens under the influence of heat. The
' covering permits the packing to be handled with equal facility asany soft packing. It is self evident that the covering will soon wear on the side which is next to the rod but it lasts for a time su'lliciently long to perbox. That portion of. the covering which always remains will also act as an absorbent in conjunction with the elastic means above mentioned and being located between the metallic cores that would otherwise come in contact with one another permit of the removal of the various rings should occasion require this.
,l/Vhen finished the packing is thoroughly and pernmnently lubricated. The lubricant is injected into the entire mass so as to thoroughly lubricate and saturate the covering and flexible means and also fill all spaces between the triangular small metallic cords or threads and care has been taken to produce a soft metallic packing which may be easily cut and fitted retaining at the same time all the qualities of a positive metallic packing.
In order. to make the invention fully understood reference is made to the accompanying drawing in which;
Figure 1 representsin sectional view a stuffing box' with the-novel packing applied therein embodying in desirable form the present improvements. Fig. 2 is an end view of the packing in form of a cable. Fig. 3 shows in end view two of such cables. Fig. 4 is an end View of the single Wire-like small metallic cords or threads of trlangular Fig. 7 illustrates another modification.
mit of the packing becoming well set in the I stufling box, b 'is the rod,c is the packing as applied and d illustrates a tightening mechanism. t
The packing illustrated in end view in Fig. 2 is made in: form of a cable say about 20 ft. long. It consists of two metallic corese, e of circular form. Each metallic core consists of a large number of small me-,
tallic cords or threads f of triangular cross section of which a number are ,shown on an enlarged scale in Fig. 4. The cores are twisted in cable fashion for the purpose above mentioned. Between two metallic cores there are provided fibrous triangular wedges g which fairly fill the space between the two metallic cores. The wedges 9 consist of textile fibers such as flax for instance and represent the elastic means in the packing and the absorbent during the application and setting of same in the stuffing box. The two metallic cores with the two wedges of textile fibers bet-ween are all inclosed in.
a textile covering 72, knit of flax or other soft textile fibers. Thus cables are obtained which may be .easilyhandled, out, bent and fitted. v a 4 When applying the packing the cable is cut into suitable lengths to form a ring around the rod. After constant pressure of t-hegland the packing assumes the shape of acom'pact mass as shown in Fig. 5 where the metal cores 6, e are shown to be of elongated; shape bearing against the rod. Succeeding sections of acking placed in the stuffing box will be su ject to precisely the same conditi'ons'and influence as above de;
4a scribed because of the arrangement of the flax wedges and the dual metallic cores within a common cover; As shown in Fig. 5 the flax wedges will appear alternately and not between two neighboring sections. This also finds expression in Fig. 3 where two cables are shown side by side without any flax wedges between the two cables. Y A'modified form of packing is shown in Fig. '6 which is constructedof two cores 6, 6 made of small metallic cords or threads of triangular cross section and surrounded by f a common covering h of textile fibers as above described but the absorbent elastic triangular wedges between the cores are omitted. Another mpdified form. is illustrated. in Fig. 7 consistin of a single core composed of metallic cor s or threads of triangular cross section and a textile covering around same.
By virtue of the construction of the above described metallic packing with its flexibl'e qualities, it will" adapt itself to any form thatmay be desired or which 'may be necessary to meet the conditions existing in'a stufling box. One particular object of the invention is to produce metallic packing which possesses all the advantages of a soft packing as regards handlin cutting and fitting and being a well lubrlcated roduct it retains .all the qualities of a positive metallic packing. The single cords or threads being of relatively large cross section do not burn out like almost hair-like metallic fine wires. Although the packingis efiicient for steam, water and ammonia t is partleularly well adapted .for use in an ammonia atmospher'e. I clalm as my invention:
1. Metallic packing in "form of a cable consisting of a flexible core composed'of small metallic cords or threads of triangular cross section twisted in cable fashion, and a covering of textile material around sald core.
QQMetallic packing in form of a cable' consisting of cores composed each ofsmall metallic cords or threadsof triangular cross 'sectionand twisted in cable fashion, and a covering of textile material around sa d cores.

5. Metallic packing consisting of rings around the rod composed each of two cores made of single cords or threads of triangular cross section and twisted in cable fashion, elastic and absorbent. wedges of textile fibers between said cores, and a textile covering common to. all,arran ed side by side so that flexible wedges are so of cores.
6. In metallic packing a core com osed ofsmall metallicicords or threads of tr1an an ely between each pair cross section and twisted in cable'fas ion,
