PATENT frieren 'ROLL FOR JORDAN ENGINES.

SPECIFICATION forming part of Letters Patent No. 533,857, dated February 12, 1895. Application filed April 9, 1894. Serial No. 506,820. (No model.)

T all whom it may cocern.- l

Be it known that I, EDWIN W. BARTON, a

, citizen of the United States, and a resident of v Lawrence, in the county-of Essex and State of Massachusetts, haveinvented new and useful Improvements in Rolls for Jordan En,- gines, of which the following, taken in con- Dection with the accompanying drawings, is a specification.

This invention relates to improvements in rolls for Jordan engines and it is carried out ever they occur on the different parts of the drawings.

A represents the conical -Jordan roll secured to the-shaft B as shown in Fig.'1. The exteriorV of the roll A has a series of annular bearing surfaces A', A', preferably turned and trued on which are shrunk or otherwise iirmly secured the metal blade holding rings C, C, which are preferably placed against abutting annular shoulders or projections a,

' a, on the exterior of the "roll A as shown in Fig. 1. r

D, D, represent the detachable blades or knives having a series of preferably elongated or slotted perforations d, d, by means of which said blades may be lockedonto the blade-holding rings C, C, as will hereinafter be described. lIn addition to such perforations I prefer to make on the under side of each blade or knife a series of notches or cut away portions d', d', as shown in detail in Figs. l and 6, although such notches may be dispensed with if so desired without departing from the essence of my invention.

Each ring C is provided with a series of notches C C', adapted to receive the blades D, and in practice I prefer to construct each of such notches so as to be capable of receiving and holding two knives or blades as will hereinafter be more fully described. One end of each notch is open and there provided with'inwardly projecting locking lips C, Q` adapted to be hooked into the blade perforations d, d, when the blades-D, D, are to be vattached to the blade holding rings of thel roll. The opposite end of each notch C is -provided with one or two steady grooves C8,

C3, (Figs. l and 4) adapted to receive and steady the blade or blades D whenlocked in position on the blade-holding rings of the roll. In attaching a blade D to the roll I hold it above the said roll as shown in the upper portion of Fig. l and drop it into the notches C', C', on the rings C, then move it slightly sidewise so as t o cause the projection C to enter the perforation d, after which the blade is moved towardthe larger end of the roll so as to cause the edge of the blade adjacent to the cut away portion d to enter the groove C3 as fully shown in Fig. 6.. W henthe blade is thus hooked into position a space Eis left betweenI its inner edge and the outer circumference of the roll. The other blades are then hooked onto the rings C, C, in a like manner after which `the wood lling bars F, F, are driven'between the successive blades, such filling pieces having out away parts f, f, (Fig. l) adapted to receive the rings C, C, when l driven in between the blades.

The inner edge of each Wood filler F is driven far enough to. restagainst the periphery of the roll, that is below the inner edge of the blades Where it is free to expand laterally intoV the space E above mentioned thus forming a lock whereby said wood fillers are firmly held in position and prevented from working loose as fully illustrated in Fig. 5.

Having thus fullydescribed the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claiml. A tapering Jordan roll having a series of blade holding rings combined with a series of blades secured thereto and intermediate wood llers having their innerv edges extended below said blades and adapted to enter a space between the blades and roll,

substantially as and for the purpose set forth.

2. A tapering Jordan roll and blade holding rings secured thereto, and having notches and lateral locking projections combined with blades having perforations adapted to receive such lock projections and cut away recesses IOC) on the inner edge of said blades and-interf mediate Wood fillers, substantially as and for the purpose set forth.

3. A tapering Jordan rolland blade holding rings secured thereto and having notches and lateral locking projections and steady grooves combined with blades having perforations adapted to receive such locking projections and cut away recesses on the inner edge of said blade and intermediate Wood lllers, substantially as and for the purpose set forth.

4. A tapering Jordan roll having blades secured on its periphery but not in contact therewith combined with intermediate Wood fillers extending below the inner edges of said blades so as to allow the inner portion I5 of such wood filler to expand laterally in the space between the roll and blades, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specication, in the presence of 2o tWo subscribing witnesses, ou this 6th day of April, A. D. 1894.

EDWIN W. BARTON.
