IVIEADER, OF UIICA, NEW YORK. REFINING-ENGINE. Specification of Letters Patent. Patented Jan. 19, 1915. Application filed March 10, 1914. Serial No. 823,801. To all who-met may concern: Be it known that I, HENRY J. 'MEADER, a citizen of the UnitedStates, residing at No. 1:2 Kernan avenue,Utica, in the; county of Oneida and State Iofilew York, have invented certain new and useful Improvements in Refining-Engines, of which thefollowing is a; specification, reference being had therein to the accompanying drawing. My invention relates to an improved rening'engine, and I declare that the following is a full, clear, concise and exact description thereof, sufiicient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts'throughout. .The device of the invention relates particularly to refining engines used in paper mills and which are commonly known as Jordan engines. The object of theinvention is to provide a more satisfactory and permanent filling, as it may be called, meaning thereby the parts which, in the construction of the engine, are placed between the blades. The engine consists in general construction of a conical case in which is revolved a conical core which may be of solid construction or made hollow. On the inner surface of the case and the outer surface of the core are mounted a series of blades running lengthwise the case and the core throughout the length or part of the length according as the shape of the case and the core permit without too close crowding of the blades. These blades consist of metal strips of given thickness and width which are securely mounted on their respective surfaces. There are a variety of means in use whereby these blades may bemounted firmly in position, unless they may be made integral with the respective body of which they are parts. Between these blades is placed what is called the filling parts, commonly of wood, being in the form of a single strip running lengthwise the case or the core and filling the space between the blades. It has been found most expedient to use wood for this filling as most adaptable for the purpose on account of its inherent qualities. It is found, however, that in the revolution of the core the stock which passes through the engine or beater is thrown violently against one side of each blade and against sectional view transverse the face of the filling adjacent to that blade. This action wears the filler away at one edge while it is worn very little at the other edge and, therefore, the filler requires frequent replacing. i My invention provides a new style of filler whlch embodies the-desirable features of the wooden. filler and at the same time obvlates the severe wear of the ordinary wooden filler. In the. drawings, nal sectional view mounted therein in Figure l is a longitudiof a case with a core full view; Fig. 2 is a the axis showing a part of the case and part of the core with some of the blades and filler thereon, and Fig. 3 is a full side view of part of the core showing the blades and my improved filler therebetween. Referring to the figures in detail, A. represents the case, B the core and D the revoluble shaft which carries the core. The several blades on the case are represented by 1 and those on the core are shown by 2. it will be understood that any suitable means may be employed for the mounting of these blades and I, therefore, do not represent any particular means as a person ordinarily skilled in the art may make his own selection. Referring to Fig. 2, the small arrows indicate the general direction of the flow of the stock passing through the engine, showing that the stock is naturally thrown against the blade and the filler at about the points indicated. In my improved construction I build the filler of two parts, one indicated by 8 and preferably made of wood and the other indicated at l and preferably made of iron. I have found by actual practice that using a strip of iron, 4, to occupy the place where the wear comes upon the filler and using strip of wood, 3, to fill the rest of the space between the blades accomplishes the perfect holding and stiffening of the blades and at the same time preserves the features which pertain to the use of wood fillers but obviates the wear which makes them of such short life. 7 I have indicated in Fig. 3, by 5 and 6, bands which may be employed to hold the filler in place, but the illustration is simply indicative of any suitable means for holding them, and I do not confine myself to any particular method or means. 1.
