July 14, 1931-. H. N. WEIR 7 JORDAN ENGINE PLUG Filed Aug. 26, 1929 Imam/ran Harry /V W Arron/wry Patented July 14, 193i UNITED STATES HARRY N. WEIR, 0F HOOSICK FALLS, NEW MACHINE 00., 0F HOOSICK FALLS, NEW

YORK, ASSIGNOR TO THE NOBLE & WOOD YORK, A CORPORATION OF NEW YORK JORDAN ENGINE PLUG Application filed August 26,

My invention relates to paper making machinery are particularly to improvements in the construction of jordans, refining engines. and the like. a

Machines of this character comprise a tapered shell provided on the interior with I fixed cutting elements, and a cone or plug having cutting elements or blades on the surface thereof, and which is axially mounted to rotate within the shell. Material to be treated is introduced into the smaller end of the device and is carried forward to the larger 'end and discharged therefrom by centrifugal force.

Many grades of stock which are introduced into the machines contain considerable foreign matter such as bits of wire, staples, paper clips and otherhard particles which are ultimately reduced by passage be= tween the cutting elements. However, these hard particles, being swept between the stationary and revolving knives, cause a great deal of wear on the device, particularly the smaller end of the plug where the, material is introduced and eventually cause the bars to become loosened and broken. In many cases the entire set of knives and wedges must be replaced. i

Even when the better grades of stock are used, the large amount of water passing through. the jordan eventually causes the wood in the wedges to warp, rise, at the end, and be destroyed, and the blades loosened. v

My invention relates to a cast conical section having knives integral therewith to form the front section of the plug. This section is fastened to the plu shaft by any suitable means, and has a note ed flange that fits over 'the movable knives and wedges thereby acting as an additional holding or. locking means, This flange also acts as a shield to protect the ends of the knives and wedges.

The section is preferably secured to the main body of the plug by lon bolts extending parallel to the shaft, an ending ina recess in the plug body. The bolts are threaded where they pass into the recess and 'are held 'by nuts andlock nuts. The recess 1929. Serial No. 388,426.

is covered to protect the nuts from being washed and destroyed. '1

From the above,- it-will be seen that I provide a cast renewable section of hardened material. The knives thereon will receive the brunt of the wear because they are first exposed to the inflowing stock and the section willserve generally to protect the ends of the knives and wedges of the plug proper My invention, therefore, includes. the novel elements and the' combinations and arrangements of elements described below and illustrated in.the accompanying drawings, in which- Fig. 1 is a longitudinal axial section of a half jordan plug, with wedges omitted, showing the renewable section moved out of contact with the plug;

Fig. 2 is a fragmentary view of the jor dan plug taken from position indicated by lines 22 in Fig. 1; I

Fig. 3 is a fragmentary view'of the renewable section taken from position indicated by lines 33 in Fig. 1;

, Fig. 4 is a perspective view of a jordan plug with my renewable section attached; and

Fig. 5 is a fragmentary perspectiveqview of a Wedge. u

Referring to the drawings, 1 represents the usual shaft to which the main body, 2,

of the plug is keyed or otherwise secured. Attached tothe. plug, 2, are the bars of knives, 3, which are secured in place by wedges, 4. The'bars, 3, and wedges, 4, at the smaller end of the plug are'notched, as shown at.17 in Fig. 1, and 19 in Fig. 5, respectively, adapting these elements to fit beneath and be retained by the flanges, 6, of the removable section as hereinafter described.

My removable section is shown generally at 5. It is conical shaped and has a notched flan e, 6, which is adapted to fit over the note ed ends of knives, 3, and wedges, 4, when drawn into close contact with plug, 2. This section is preferably made of cast manganese steel but it may be constructed of any knives, 7. These blades are so disposed around the periphery of section, 5, that they will align with the bars, 3, of plug, 2, when section, 5, is secured to the plug. The outside and working edges of the blades may be machine ground to a true conical surface.

The metal filling, 8, between knives, 6, is so cast that it" will be substantially flush with -the tops of wedges, 4, when the section is attached to the plug.

Section, 5, is provided with radial slots, 9, as shown, into which bolts, 10, are placed.

These bolts pass through cylindrical holes, 5

11, in the plug and which are parallel to shaft, 1. These bolts, 10, terminate in a recess, 12, at the larger end of the plug and .are threaded to receive nuts, 14, and lock nuts, 15. Covering this recess, 12, is plate,

' 16, secured to the plug by any suitable means.

When section, 5, is secured to plug, 2, the

notched flange, 6, overlies and holds 1n placeboth the wedges, 4, and the blades, 3, by

-' bearing against shoulders formed by notches,

17 and 19.

From the foregoing, it will be apparent that any hard material which enters the device will first come into contact with the blades or bars on the removable section, 5,

and, since these bars extend for a rather substantial distance axially along the surface of the plug, such material will be pracexcessive the end section may be easily removed and replaced by simply removing the bolts, 11.. While I have described my invention in its preferred embodiment it is to be understood that the words which I have used are words of description rather than of limitation and that the drawings are merely illustrative. Hence changes, within the purview of the appended claims, may be made withoutdeparting from the true scope and spirit of my invention.

at I claim is 1. The combination with a jordan plug, of a metal sleeve, having integral knives, fitting over and forming the smaller end of the plug.

2. The combination with a jordan plug having removable knives and wedges, of a metal section having integral knives thereon and fitting over the ends of said wedges at the smaller end of said plug; whereby said wedges are secured in place.

3. The combination with a jordan plug having removable knives and wedges, of a metal section having integral knives thereon and fitting over the ends of said knives at the smaller end of said plug; whereby said knives are secured in place.

4. The combination with a jordan plug having removable knives and wedges, of a metal section having integral knives thereon and fitting over the ends of said knives and wedges at the smaller end of said plug, whereby said knives and wedges are secured in place.

5. The combination with a jordan plug, keyed to a shaft, of a cast metal conical section, with knives integral therewith, having a tapered, recessed flange closely embracing the end of said plug.
