Application filed January 31, 1912. Serial No. 674,485.

Patented Oct. 15, Eli-912.

To all whom it may concern:

Be it known that I, HAYDEN A. KERN, a citizen of the United States, residing in Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Composition of Matter Intended Particularly as a Oomposition to Militate Tapping of Aluminum or the Like, of which the following is a full and comprehensive exposition and specification, being such as will enable an ordinary machinist to prepare and practice the same with absolute exactitude.

In tapping aluminum castings, for instance, that is in forming threads around in an aperture therein, great dificulty is experienced by reason of the chips or cuttings adhering and sticking between the threads of the tap-screw, thereby locking the tapscrew and necessitating its removal and cleaning before further advance can be made; in attempting to force the tap forward after it has stuck frequently results in breaking the tap-screw; all of which causes an inordinate amount of trouble and consequent loss of time and waste of material.

To overcome these troubles and objections is the primal object. of my invention, also providing a new article of manufacture which can be made and sold at a comparatively low price, and which willbe highly eflicient in practice, especially in working aluminum or kindred metals.

Other objects and advantages may be suggested by the specification or may be found by practice, and that which is new will be set forth in the appended claims.

In order that the preparation and the use of my invention maybe fully understood and appreciated ll will now take up a detailed description thereof, in which it will set forth the invention as completely and as comprehensively as It may.

The basic element of my composition is of a ceraceous nature, such as beeswax or its equivalent, forming the body element which is to be brought to a plastic condition by the admixture of a solvent, such as gasolene or its equivalent; and in some instances by the addition of a thinner, such as turpentine or its equivalent, the latter also being employed as an odor neutralizer.

For tapping aluminum I have found that,

the :toiliowing named proportions will give the most satisfactory results: Beeswax, one pound; gasolene, five pounds; turpentine, one pound. However the proportions given may be variously changed and the turpentine may be entirely dispensed with.

In fact the gasolene may be dispensed with and the turpentine may be employed in stead. Or both the gasolene and the turpentine may be dispensed with, providing however that another solvent be employed instead. The essential requisite being that the wax must be reduced to a usable paste.

The turpentine not only acts as a thinner, but the odor thereof, combined with the odor of the other ingredients, and by reason of the chemical actions set up by the interaction of the elements, tend to negative the odor of all, thereby preventing the solution from being'ofiensive or deleterious to the user.

In practice a small amount of the paste may be placed or spread on the tap-screw, by means of a paddle or otherwise, then as the tap-bolt enters the aperture to be threaded the chips wili not adhere to the but they will slide forward as the tap cuts its way, thereby making the tap-bolt to be seif-cleaning, and permitting the operator to complete the threads in each aperture without stop ping the forward movement of the tap, or without removing the tap from the aperture, until the threads are completed therein, thereby overcoming the crux of tapping aluminum or the like, and accomplishingthe desideratum of this invention.

It is evident that my invention may be employed for other uses than those stated, and that the ingredients and the proportions may be variously changed, without departing from the spirit of my invention or sacrificing any of the advantages thereof.

Having now fully shown and described my invention, and the best means for its preparation and use to me known this time, what claim desire to secure by Letters Patent of the United States, is-

1. A composition to facilitate the tapping of aluminum or the like consisting of bees wax and a solvent formed into a pasty condition.

2. A composition to facilitate the tapping of aluminum or the like and consisting of beeswax, a solvent, and odor neutralizing agent.

3. A, composition to tacilitate the tapping of aluminum or the like, consisting of beesscribed my name to this specification in the wax and gasolene fornipd into a paste. presence of two subscribing witnesses.
