JOHN DIXON, OF PHILADELPHIA, PENNSYLVANIA.

DIS INTE GRATING-CYLINDER.

To all whom it may concern:

Be it known that I, JOHN DIXON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Disintegrating-Cylinders, of which the following is a specification.

This invention relates to disinte rating cylinders, and more articularly to cylinders for disintegrating 'brous substances, the object being to provide very novel means for attaching the ribbon saw to the same, so that it can be easily and quickly secured thereon without injuring the cylinder in any way, thereby overcoming the di'lficulties now existing with cylinders of this character, as everytime a new ribbon saw is inserted, the cylinder is injured to a certain extent, and has to be refinished, and. in course of time the spiral groove in the periphery of the same has to be deepened to receive the ribbon saw.

A further object of my invention is to provide means for securing the saw which can be readily attached to the ordinary cylinder now in use without changing the same in any manner.

Another object of my invention is to provide a ribbon saw with a beveled side. I accomplish this object by winding a flat wire in the ordinary spiral groove of the cylinder, which is of such a size that it extends up above the periphery of the same and forms a spiral groove to receive the ribbon saw which is secured therein by swaging the wire, the wire being wound therein under tension and secured at its ends.

These objects are obtained by the novel arrangement and construction of parts hereinafter fully described and shown in the accompanying drawings, in which:

Figure 1, is a longitudinal sectional view of the cylinder partly in elevation showing the manner of securing my ribbon saw in place. Fig. 2, is an end view of the cylinder. Fig. 3, is a detail section showing the manner of securing the ribbon saw between the wire by swaging the same.

In the drawings A, indicates a cylinder having a spiral groove in its periphery, in which is adapted to be wound a malleable fiat Wire B, the width of the wire being sufli- Specification of Letters Patent.

cient to allow it to extend above the periphery of the cylinder a suflicient distance to form a spiral groove. The ends of the wire are secured to the respective ends of the cylinder by any suitable means, not shown, so that it will be securely locked in the groove. The ribbon saw C, is then wound in the groove formed by the wire, one side of the saw being provided with a beveled portion C over which the adjacent edge of the wire B as shown at B, is adapted to be swaged, where by the wire will be securely locked in positlon,

so that it cannot move in any way, the ends being secured in some suitable manner. It oil. course, being understood that the ribbon saw is wound in the groove under great tension, so that it will lie flatly in the same, the teeth of the saw projecting out a sui'licient distance so as to allow the teeth to pass through the fibrous substances to be disintegrated. By this arrangement the cylinder is thoroughly protected against foreign matter which gets mixed up in the fibrous substances to be disintegrated and sometimes injures the cylinder so that it has to be refaced. When it is desired to replace a new ribbon saw, it is only necessary to release the ends of the wire so that it can be readily unwound which will carry with it the ribbon saw, thereby saving a great deal of time and labor.

While I have shown and described the ribbon saw with a beveled portion, it of course is not necessary, as it can be secured therein without the same, but by practical experience, I have found that the ribbon saw will be held much tighter within the groove.

From the foregoing description it will be seen that I have provided novel means for securing the ribbon saw to a cylinder, so that it can be readily taken oil and one which will protect the cylinder, thereby increasing the life of the cylinder, and time and expense of having the cylinder regrooved and finished. Having thus described my invention what I claim as new and desire to secure by Let ters Patent is :l

A disintegrating cylinder provided with a spirally grooved periphery, a ribbon saw disposed spirally around said cylinder, and located between the convolutions of the spiral groove, said saw having one side beveled, a malleable saw securing and groove forming Wire inserted in said spiral roove, and of a In testimony whereof I have signed my depth greater than the dept of the groove, name to this specification in the presence of whereby said wire forms a groove for the two subscribing witnesses.
