Specification of Letters Patent.

y Application filed September 21,1905. Serial No. 279.884.
Packing, of which 4the following is a specifi-A' cation. g
The principal object of the present invention is to provide a packing for use especially in connection with .high steam-pressuressuch, for example, as those to which locomotive throttle-valves are subjected-and which packing shallv be eiiicient, reliable, durable, and comparatively inexpensive,
The invention comprises the improvement's to be presently described and finally claimed, and the nature, characteristicfeatures, and scope ofthe invention 'will be more fully understood from the following description, taken in connection with the accompanying drawings, forming-part hereof, and in which- Figure l is a perspective View of a packing embodying features of the invention. Fig. 2 is a sectional View illustrating the same in application to a gland or stuffing-box, and Fig. 3 illustrates"conventionally in plan and section some of the material which enters into the' constructionI of the packing.
In the drawings, 1 and 2 are wed e-shaped sections consisting, respectively, o a roll-of wired asbestos cloth cemented and pressed into wedge form. The wired asbestos cloth 1s shown in Fig. 3, in which 3 represents the.
asbestos strands, and 4 the Wire-strands; but of course the strands may be differently arranged. The various layers of the rolled cloth may be cemented together, as by means of so-called rubber-cement, and therolled sheet, which vwould normally be ol cylindrical form, is consolidated and pressed into wedge form by any suitable means.
5 is a rubber cushion, and its purpose is to aord the wedge-sections freedom of sliding motion in response to the requirements to which they are subjected.
6 is an envelop or wrapper of asbestos cloth or material either with o r without wire, and it surrounds the wedges and the rubber cushion.
The packing may be lubricated, for example, With graphite. Externally the packing is generally of rectangular forni, but is {ivesided', so that one of its corners is beveled, as
. at 7. This accommodates the packing to the wall ofthe stui'ling-box. It will be obvious to those skilled in the art to which the invention relates that modifications maybe made in details without departing from the spirit thereof. Hence the inventlon is not limited further than the prior state of the art may require; but,
Having thus described the nature and obljects of my invention, what I claim as new,
and desire to secure by Letters Patent, is-
g l. A packing comprising a wrapper or cnvelop, a rubber cushion and two wedgeshaped sections each consisting of a consolidated roll of wired asbestos cloth, substantially as described.
2. A packing comprising an asbestos wrap.- per or envelop, a rubber cushlon and two wedge-shaped sectlons each consisting of'a vconsolidated roll of wired asbestos. cloth, sub? stantially as described.
In testimony whereof. I have hereunto
