PACKING FOR STUFFIN G BOXES. APPLICATION FILED JUNE 28, 1909.

I D. C. ANDREW B GHANA C0,. PNOTO-LIYHOGRAPHERS, WASHINGYON FETCH OSCAR LINGNER, OF DRESDEN-NEUSTADT, GERMANY.
PACKING FOR STUFFING-BOXES.
9&5, 790.
To all whom it may concern:
Be it known that I, OSCAR LINGNER, a citizen of the Kingdom of Saxony, residing as Dresden-Neustadt, Saxony, in the Empire of Germany, have invented certain new and useful Improvements in Packing for Stuifing-Boxes, of which the following is a specification.
Packings for stufling boxes are well known in which asbestos hemp or cotton fibers are used with metal shavings. Such packing consists of a loose dry mass or of a mass that can be kneaded. Sometimes these substances are also plaited or braided. All such packings however have serious disadvantages as owing to the heating and to the pressure, the fat is easily expressed from the wrapping, whereupon the mass remaining in the stufling box soon becomes felted. XV hen such a mass dries, damage to the piston rod easily results. According to this invention the drying of the packing is prevented. The yarn before it is plaited or braided, is treated with a preparation of fiber and metal shavings. The treatment is elfected in such manner that the yarn is impregnated through and through with the fiber preparation and the soft metal shavings by means of a felting or similar process. The fiber thus obtained is then subjected to a further treatment. Hopes of any desired cross-section, thickness and length are prepared from it. It is also possible to prepare from the new packing material, single rings which can be placed around the piston rod. Packing of this kind acts to the highest degree as automatically lubricating, it is very elastic and cannot damage the piston or pump rods.
The yarn used can be asbestos, hemp, cotton or the like.
Specification of Letters Patent.
Application filed June 28, 1909.
Patented Jan. 11, 1910.
Serial No. 504,709.
The invention is illustrated in the accompanying drawing, in which a piece of rope of rectangular cross-section is shown.
The single threads a are plaited or braided as shown. Each thread a is impregnated single in the above mentioned manner before plaiting.
The process can be carried out, for instance, in the following manner: A paste consisting of fibrous material and soft metal shavings is placed in a vat and thoroughly stirred. The threads a are guided through the said paste, and the threads can be energetically pulled to and fro by means of suitably formed arms or the like, that is to say, they can be exposed to a kind of felting process, a great deal of the substance (fibrous material and soft metal) being absorbed by the threads.
That I claim as my invention and desire to secure by Letters Patent is 1. A process for manufacturing stuffing box packing, in which fibrous packing yarn is impregnated, before it is braided or plaited, with a fiber preparation containing soft metal shavings.
2. As an article of manufacture stuffing box packing of fibrous material, the yarns of which are impregnated with a fiber preparation containing soft metal shavings, before the yarn is braided or plaited. V
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
OSCAR LINGNER.
