Description

- NON -METALIJIC BEARING.

Application filed May c, 1909.' serrial Masino.

To all whom t may concern.

Be it known' that I, CHARLES O. L.

' CARDELL, a citizen of the United States,rand. a resident of Pearl River, in the county of Rockland and State of New York, have invented a new and Improved Non-M-tallic Bearing, of which the following is a full, clear, and exact description.

' The object of the invention is to provide a new and improved non-metallic bearing, pulley, bushing and like article, formed of wood and treated in suchv a manner that the bers are hardened, the wood is permeated with a special lubricant andpreserved, to render the article exceedingly serviceable for use in spinning and other machines es-v peci ally with.

The invention consists in combining wood With copperas to'harden the fibers, drying and non-drying oils and beeswax t-o lubricate the wood, and creosote to preserve it.

The invention further consists in a method whereby the wood is first subjected to a fiber hardening bath, then to a lubricating bath to permeate the wood with a lubricant, and finally preserving the woodby the addition of creosote to the second bath.

In the accompanying drawings, Figure 1 as constant oiling can be dispensed 1s treated as above mentioned; Fig. 2 is a cross section ofa metallic pulley having a nonmetallic bushing; and F ig. 3 is a cross section of a shaft journal having a non-metallic bearing. l

In detail, I proceed as follows: The wood used for the formation of the article is preferably maple, birch or other hard wood, and the wood is fashioned into the desired article, such as a pulley, for instance, as shown in Fig. l, or a bushing or a bearing, as shown in Figs. 2 and 3. The fashioned wood is first subjected to a bath formed of copperas in the proportion of one pound to three gallons of water, and for about two hours, with the bath heated to about 50 centigrade. By subjecting the wood to this bath the fibers are set and hardened. The wood is then removed from this bath and is left to dry and then subjected to a second bath formed of One-half a gallon of rosin oil, one gallon of linseed oil, two gallons of cotton seed oil and one pound of beeswax, the bath being just hot `enough to be under the bolling point, and the soaking of the wood is continued for about twenty hours, so as to cause the ingre- Specication of Letters Patent.

dients of the bath to permeate the wood.

It is understood that of the ingredients of the second bath, the rosin oil and the linseed oil are dryingoils, while the cotton seed oil4 is a non-dry1ng oil. After the expiration pure creosote is added 'to the second bath, and the article is kept in this bath for four more hours, and is left therein until cool, the heat being removed froln under the vat containing the bath. The article, after being removed from the second bath,

is varnished, preferably' with carriage varnish, to keep the ingredls ents with which the wood is saturated Within the wood.

The article produced requires -no oil when used, and it can be subjected to a high speed,

`without danger of overheating or'burning.

Having thus -described my invention, I claim as new and desire to secure by Letters Patent:

l. As an article of manufacture, a nonmetallic material for pulleys, bushings, bearings andthe like, consisting of wood treated with copperas to harden the fibers permeated w ith drying oils, non-drying oils,

l and beeswax as a lubricant.

2. As an article of manufacture, a nonmetallic material for pulleys, bushings, bearings, and the like, consisting of wood, treated with copperas to harden the fibers, with drying oils, non-drying oils, and beeswax to lubricate the material and with creosote.

3. As an article of manufacture, a nonmetallic material for pulleys, bushings, bearings and the like, consisting of wood, treated with copperas to harden the fibers, with drying oils, non-drying oils, and beeswax as a lubricant, with creosote to preserve the wood and coated with varnish. p

4. The herein described method for forming a non-metallic bearing, pulley, bushing and like article, consisting in subjecting fashioned wood to a bath of copperas, then subjecting it to a hot bath formed initially of drying oils, non-drying oils and beeswax, with a final addition of crosote.

5. The herein described method for form-A ing a non-metallic bearing, pulley, bushing, and like article, onsisting -in subjecting fashioned wood to a bath'of copperas, then subjecting it to a hot bath formed initially of drying oilsnondrying oils and beeswax, with a final addition of creosote, then coating the article with varnish.
