TENT l'@ l METHOD OF TREATING LOOM-SHUTTLES OR OTHER WOODEN WEARING-SURFACES.

SPECIFICATION forming part of Letters Patent No. 780,182, dated January 17, 1905. Application filed July 23, 1904. Serial No. 217,840.

To (tZZ who/n it may concern/.-

Be it known that I, OSCAR E. HoLDRIDen, a citizen of the United States, residing in New Bedford, in the county of Bristol and State of lvlassachusetts, have invented a new and 1mproved Method of Treating Loom-Shuttles or other Wooden lVearing-Surfaces, of which the following is a specification.

It is the object of this invention to treat the wearing-surface of a shuttle or any wearingsurface of wood with a lubricant in such a manner that the said surface will wear very much longer without producing the sticky effect which is common in shuttles which have been treated with compounds containing wax or shellac and without gumming up, the lubricant being applied in such a manner that it furnishes a constant supply retained by the fiber of the wood and provided at the surface thereof.

In the accompanying drawings, Figure 1 is a side elevation showing the wearing-surface of a shuttle treated by my method. Fig. 2 is an enlarged cross-section taken on line 2 2, Fig. 1. Fig. 8 is an enlarged view in elevation of a portion of the wearing-surface. Fig. 4: is a view of a small portion of a wearingsurface, very much enlarged, after having been subjected to my treatment. Fig. 5 is a view in elevation, showing a portion of the surface in which there is a slight modification of the treatment.

Referring to the first four figures, my improved method consists first of piercing the surface of the shuttle with a large number of needle-holes extending to the depth'of, say, one-sixteenth of an inch, said holes being tattooed in any suitable manner, but prefer ably by a number of needles set in a suitable frame and forced in by any desired power, and, second, in rubbing or brushing or forcing into said holes a suitable lubricant, such as a composition of black-lead, turpentine, and sperm-oil. When the needles are thus forced into the wood, while they penetrate to the depth of a sixteenth of an inch they do not break the fiber, but spread the fibers apart,

and after the black-lead has been applied the fibers close on and around it, holding it firmly in place and producing a smooth and hard self-lubricating surface to the depth of a sixteenth of an inch, so that the shuttle can wear to that depth and still retain its lubricating quality.

In Fig. 5 1 have shown the invention ap plied in a slightly different manner, but without departing materially from my method. In this figure the surface is treated with a number of knife-points instead of needle-points, thus providing spaces for the lubricant, the effect being precisely the same as far as spreading the fibers of the wood is concerned.

It should be understood that in all figures except Fig. 1 both the width and depth of the holes are on a larger scale.

In a shuttle treated in the above manner the black-lead does not gum up, but wears smooth and glossy and not sticky. Hence it is not necessary to scrape the shuttle with a knife or sandpaper, as is now the common practice. Scraping my shuttle, however, will do no harm, as if the lead or lubricant is scraped off the surface it will quickly form again as it runs in the loom.

Having thus fully described my invention, what I claim, and d sire to secure by Letters Patent, is

The method or process of treating loom-shuttles and other wooden wearing-surfaces, consisting in piercing the wearing'surfaces to a slight depth without breaking the fiber of the wood by means of needles, knives or other suitable instruments, filling the small spaces thus produced with lubricant, and allowing the fibers of the wood to close over or around said lubricant, substantially as herein described.

in testimony whereoflhave signed my name to this specification in the presence of two subscribing witnesses.

OSCAR E. HOLDRIDGE.
