PROCESS OF MIXING WOOL WASTE AND GREASE.

Application filed November 17, 1919.

To all whom it may concern Be it known that we, Flinn C. FANTZ, a citizen of the United States of America, and a resident of St. Louis, St. Louis County,

and State of Missouri, and Es'rns G. RATrI- BONE, a citizen of the United States of America, and a resident of Tacoma, Pierce County, and State of IVashington, have invented certain new and useful Improvements in Processes of Mixing Wool aste and Grease, of which the following is a specification, reference being had to the accompanylng drawing, forming a part thereof.

Our inventlon relates to the mixing of very viscous liquid or semi-solid material such as grease with fibrous materials such as wool waste, and has special reference to the production of what is known as wool waste grease.

One object of our invention is to provide a simple and effective process for thoroughly and expeditiously mixing ingredients of the character above indicated.

Another object is to provide a simple and effective apparatus for practicing the aforesaid process on a commercial scale.

The most effective method hitherto known for accomplishing the objective results of method is replaced by a rotary mixer having combining prongs or teeth which carry the mass to be mixed for a certain distance up the side of the rotary device and pull the fibres through the grease to a greater or less extent, before the mass is allowed to fall oil of the teeth or prongs.

In order that our invention may be thoroughly understood we will now proceed to describe the same in the following specilication and will then point out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a sectional elevation of a mixer arranged and constructed in accordance with Serial No. 338,639.

or mixingdrum 13 having annular pro-' jections or ribs 14.+15 which respectively engage the rollers 1111 and 1212. The drum is provided with a driving gear 16 which meshes with a pinion 17 afiixed to a driving shaft '18.

The drum is provided with any suitable gate or opening 19 which, in the arrangement illustrated, is pivoted at 20. Theinterior walls of the mixer are provided with a plurality of teeth or fingers 21 which extend inwardly in a radial direction but are preferably curved or hooked to a slight extent in the direction of rotation. In order to obtain the best results the fingers 21 are arranged in a staggered relation as shown in the drawing.

In performing the mixing operation the proper proportions of separated wool waste, or othersuitable fibre, and grease, or other material of similar characteristics, which it is desired to mix, are introduced into the mixing drum 13. The drum is then rotated in the direction of the arrow in Figure 1 with the result that the mass of grease and waste is not only rotated with the drum, but is also shredded or combed by the teeth or projections.

Attention is directed to the fact that the mass is subjected to a kneading action by being carried up the sides of the mixer as are absolutely unsuited for this purpose, be-

cause either the fibrous material is not properly intermingled with the grease, or, if stir rers, paddles or other devices of like character are employed, they merely gather up a greater and greater mass of fibres and separate them out of the grease and clog the stirring mechanism instead of mixing them as desired.

Apparatus of preferred form and con struction have been illustrated and described for the purpose of showing a wayin which this invention may be used, but the inventive thought upon which this application is based, is broader than these illustrative embodiments thereof, and we therefore intend no limitations other than those imposed by appended claims.

What we claim is 2 l. The process of impregnating a fibrousearrier with a grease component which consists in mixing said carrier and grease comme ane ponent together with a rotary motion While at the same timesubjecting the mass to a shredding or combing action.

2. The process of impregnating fibrous waste material with grease which comprises physically mixing the two' components by first introducing the required quantity of waste material and grease into a cylinder:

having inwardly projecting teeth, then revolving the cylinder so that the teeth successively raise the waste and subsequently drop it back upon the body of grease until the waste material has become thoroughly impregnated with thegrease.

In witness whereof. I have hereunto set my hand this 27th day of October, 1919.
