11111111111311. JOINT MAKING PACKING.

110'. 530,694. Patented Dec. 11, 1894.

UNITED STATES PATENT OFFICE;

REINHOLD KRUGER, or BERLIN, GERMANY.

JOINT-MAKING PACKING.

SPECIFICATION forming part of Letters Patent No. 530,694, dated December 11, 1894. Application filed December 13, 1893. Serial No. 493.598. (No model.)

To all whom it may concern.-

Be it known that I, REINHOLD KRIJ'GER, of 102 Friedrichstrasse, Berlin, in the German Empire, have invented a new and useful Improvement in J oint-Making Packing, of which thef ollowin g is a specification, reference being bad therein to the accompanying drawings.

My invention relates toan improved construction of packing ring, which is capable of safely resisting any steam pressure, provides a tight joint without excessive strain, and also does not lose its efficiency even when the joint is frequently broken.

The invention consists of a hard metal core with a soft packing material combined in such manner that the hard metallic core and the packing material cannot be detached or sep-' arated the one from the other, while at the same time cracks or splits in a direction transverse to the width of the packing are avoided.

In the accompanying drawings which illustrate my invention Figure 1 is a view in plan illustrating the hard core of my improved packing ring. Fig. 2 is a similar view showing the combinationof the hard metallic core and the soft material applied thereto, and Fig. 3 is a View in section through the improved packing ring.

Throughout the views similar parts are marked with like letters of reference.

The hard metallic core b is made in the form of a disk ring, and it has a series of holes a, formed through it as shown by the drawings. Through these holes a the cords d of suitable material are braided or threaded. It is immaterial how the cords are braided or threaded through the holes a, but it is preferable to braid or thread one cord through all the rows of holes and not to use a separate piece of cord cPfor each row. The reason why this construction is to be recommended,

is that in this case only the two ends of the cord have to be fastened whereas if more than one length of cord is used the number of fastenings is increased.

To facilitate the use of but one length of cord the rows of holes may be arranged in spiral form to facilitate the braiding or threading.

The action of this packing. ring is as followsz-When the packing ring is placed between the flanges to be packed and the flanges I are screwed tightly together the packingcords are squeezed flat and there is formed at both sides of the hard metallic core a a coherent or continuous surface 0 which has the appearance of an ordinary packing plate, but this similarity is solely external as my improved packing' plates or disks are merely placed on metal rings.

With the packing rings at present employed a permanent tight joint can not be depended on because they are either forced out laterally, or crack or tear; but with this improved packing ring this contingency can not happen because the packing is firmly held together by and connected to the hard metallic core.

This same feature also distinguishes my improved packing ring from those packing disks c which are cemented to the metal rings, as in these, the adhesive medium rapidly becomes destroyed in consequence of the different expansion of the materials employed, the result being that the packing disk is forced out by the constant steam pressure, and leaky joints result, while with packing rings constructed according to my invention the steam pressure cannot force ontthe packing because the lat ter is interwoven with the hard metallic core,

It will be obvious that in case of repair, my 1 improved packing ring has the advantage that only the packing need be replaced, while the hard metallic core can be used over and over again.

A further advantage that results from the use of my improved packing ring is that the packing disk cannot possibly become forced out from between the flanges of the joint.

The packing is confined to the surfaces of the ring between its inner and outer edges, leaving the latter exposed, which is important if the ring is to be held in a groove, or it is desired to protect the packing material from the action of a fluid passing through the central opening of the ring.

What I claim, and desire tosecure by Letters Patent of the United States, is-

1. A packing consisting of a flat metallic disk having holes therein from one to the other side, and a cord of soft fibrous material braided or threaded loosely through said holes, to be thereby detained in place and form a substantially continuous packing sur--- too cords of soft fibrous material threaded through I 5 said openings, between the inner and outer edges of the ring to fill the openings and also form a substantially continuous packing surface on the core when subjected to pressure,

and leaving the metallic edges of the core ex- 20 posed substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

REINHOLD KRUGER.
