BANDLESS BEATER ROLL AND JORDAN PLUG Filed Feb. 7, 1935 2 Sheets-Sheet 2 @Etty/man1 Patented June 2, 1936 UNITED STATES PATENT OFFICE John D. Haskell, Fulton, N. Y., assgnor to Dilts Machine Workslnc., a corporation of New York Application February 7, 1935, Serial No. 5,488

v4 Claims. (Cl. 92-22) This invention relates to bandless beater rolls and Jordan plugs or the like, in which class of devices the roll`4 construction is usually made up of separate heads or spiders into which the fly bars are keyed by means of wedges. The object of this invention is to provide primarily a roll of a solid drum type, although the interior may be cored out, and similarly the construction may be applied to the formation of the customary Jordan plug and shaft.

In the form of construction for which a patent is now solicited, the cylinder or plug is provided with spaced milled slots of dovetail cross section, and in place of a number of individual keys or wedges there is employed one long wedge-shaped spline which may be inserted eitherseparately or with the y bars or Jordan knives and driven endwise into the slots. rIhis provides a. bearing for the bar throughout its whole length, and it may be easily removed by driving the bar and spline endwise out of the drum or plug.

One objection to present types of Abandless beater rolls and Jordan plugs is that after several refillings the slots or grooves become worn which necessitates theuse of thicker bars or knives, making it obligatory to carry a considerable stock of various thickness steel to take care of replacements. With the construction comprised in thel present invention, the `bars or knives may be standard at all times-but splines of varying size may be employed to take up the Wear.

In the accompanying drawings illustrating this invention, Fig. 1 represents in section a peripheral portion of a roll with this invention applied thereto.

Fig. 2 is a similar section of a roll with'a modified form of this invention applied thereto.

Fig. 3 shows a pair of adjacent beater bars in section with the required iilling between them and the poured metal locking element arranged to secure the bars and lling.

Fig. 4 is a sectional view of a portion of a roll or plug showing spaced fly bars orknives constructed in accordance with this invention, and showing a modied form of the arrangement of bars or knives secured to the roll, with the filling between adjacent bars, and the metal vbar locking material which may be poured in from the outer surface of the filling.

Fig. 5 represents in section a portion of the periphery of a roll or plug showing a pair of adjacent ily bars with the wood lling between them extended somewhat beyond the periphery of the roll, and showing also the cast metal wedges at the sides of the bars connected through the bars and wood filling to secure the bars in the roll.

Fig. 6 `is a sectional view similar to Fig. 5, but showing y bars having recesses adapted to receive and engage portions of the cast metal securing Wedges, and illustrating an inverted T-shaped passage in the wood lling containing the cast metal securing material passing through the bars and joining the cast metal wedges.

Fig. 7 is a. sectional view of a portion of a. roll or plug with a single fly bar of ordinary form and wood lling against the side of the bar, with the metal securing material introduced at the side of the wood lling and passing through the filling and bar and integral with the cast metal securing wedge engaging the bar and roll.

Fig. 8 shows a pair of adjoining fly bars of the same` form as the bar shown in Fig. '7, with widened wood filling having an inverted passage of T-shape filled with the cast metal securing material passing through the wood lling, through the bars and connecting the cast metal bar holding wedges at the sides of the bars.v

Fig. 9 is a fragmentary perspective view of one end of a fly bar of the type shown in Figs. 'I and 8, showing the wood lling against the bar, and setting forth also the spaced holes through the bar and the spaced inverted T-shaped passages in the filling which are arranged in communication with the holesthrcugh the bar.

Throughout the drawings and description of this invention the same number is used 'to refer to the same part.

Considering Figs. 1 to 4, the roll I has lengthwise Wedge-shaped slots or grooves 2 for the bars 3 and 4. The bar 3 may be milled or rolled to give a thinner cutting edge if desired. The bars, as shown by bar 4 have the reentrant portions 5 engaged by the splines 6. It is not, however, intended to limit this invention to the particular wedge-shaped formations illustrated and described, as such formsk may be readily changed by those familiar with this kind of apparatus.

Considering Fig. 2 there is set out a cluster filling with splines on both sides of the knives. In this gure the roll 'I has the groove 8 occupied by the knives or bars 9 and I0, with the filling piece I I introduced between them. The continuous splines I2 are driven in on opposite sides of the knives. l

In Fig. 3, the bars I3 and I4, each of which has the usual reentrant portion I5 and heel I6, are separated by the wooden filling wedges I1 and I8. In this figure it will be noted that the bars are provided with orifices oriapertures I9, which are ordinarily round holes through the bars, but which may be oblong or rectangular as chosen. and those apertures register with the passages or apertures 20 of 4inverted T-shape and formed in the wooden filling. Metal bar locking material 2| is poured into the apertures in molten condition and serveslto lock the bars and filling securely together. The metal locking material may be hard Babbitt metal or any other like material that cools quicklyv and will not tend to enlarg the aperture by burning the wood filling.

In Fig. 4, the roll 22 has the regular grooves 2 3 with bars 24 and 25 therein, secured bythe continuous spline 26 as previously'explained. The filling 21 between the bars has the inverted T- shaped passage or aperture lled with the metal locking material 29 in the holes through the bars as well as in the passage 28.

The modification shown in Fig. comprises the bars 30 and 3| with the wood filling 32 projecting somewhat beyond the periphery of the roll or plug 33. 'I'he bars and iilling are placed in the wedge-shaped or convergent cavity 34 in the roll, and the molten locking metal when poured in forms the side wedges 35 and 36 integrally joined by the coupling 31 of the metal which passes through the bars. The metal rnay 'be introduced by way'of the side duct 38 lindicated in broken lines, and it will be noted that lthe cast wedges 35 and 36 each rpossesses projecting lugs such as,.lug 35' which engage corresponding depressions in the sides of the convergent cavity 34 in the roll.

Regarding the modification illustrated in Fig. 6,

roll or plug.

Respecting the modification rset out in Fig. 7,V

the fly bar 48 occupies the convergent cavity49 in the rollor plug 5l),` wood fillingv` 5| being arranged on one side of the bar. The cast locking metal 52 lls an L-shaped passage intheroll at the side of the filling and passes through the Lfilling 'and bar forming the side wedge of cast metal 53, engaging the reentrant portion of the illustrated.

Considering Fig. 8 the bars 54 and 55 are 1ocated in the convergent cavity 56 of the roll or plug 51, and the wood filling 58 between the bars extends somewhat beyond the surface lof the roll. The Babbitt metal lies in inverted T-shaped-form in a corresponding passage'in the filling 58, the metal 59 passing through the bars to the left and right thereby casting the side locking wedges 60 and 6|.

In the explantory Fig. 9, the iiy bar y54 has spaced holes 62 and 63, and the wood fllling'has bar as the inverted T-shaped passage comprising the vertical portion 64 for the introduction of the Babbitt metal in molten condition, and thetransverse passage portion 66 which as shown registers with the hole 62 through the fly bar 54. Filling 58 5 has a second passage for the babbitt comprising the entrance portion 65 and the transverse portion 61 registering with the hole 63 in the bar. As many spaced bar holes and filling passages as may be needed are contemplated in the purview of this invention.

In the practice of this invention, it will be noted that the fiy bars may be doubly secured, in one instance by the use of the continuous splines, and additionally by the cast metal locking mate- 15 rial. Or, the locking metal may be arranged as shown in the several modifications to.- adequately secure Vthe bars.

When need arises, the bars can be removed with the splines by using a chisel to chip out the wood filling, and then driving out the bars and splines endwise. y f
