DEVICE OR, MACHINE FOR INSERTING FILLER-BARS IN BEATER-ROLLS.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed November 24, 1917. Serial naeoases.

To all whom it may concern:

Be it known that I, CLEMENT F. SIssoN,

' a citizen of the United States, residing at WVhite Pigeon, in the countyof St. Joseph and State of Michigan, have invented certain new and useful Improvements in Devices or Machines for Inserting Filler-Bars in Beater-Rolls, of which the following is a specification.

This invention relates to a device or ma chine for inserting filler bars in beater rolls. It has been the common practice to insert the wooden filler bars in beater rolls by driving them in with sledges. This. requires a good deal of time and effort and frequently results in the splitting orbreaking of bars and quite conimonlyiirtlie crushing of the grain of the bars hammered upon.

The main objects of this invention are:

First, to provide a device for inserting filler bars into a beat-er roll by the aid of which the work may be quickly and easily performed and without injury to the filler bars, and also, without liability of breaking the tiller bars or the beater roll.

Second, to provide a device for this purpose which comprises a hydraulic press adapted to be motmted on the shaft of a heater roll so that the filler bars may be gradually forced to position in the roll.

Further objects, and objects relating to structural 7 details, will definitely appear from the detailed description to follow.

I accomplish the objects of my inventionby the devices and means described the following specification. The invention is clearly defined and pointed out in the claims. A structure which is :a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a detail longitudinal sectlon through a beater rollwith my improved device moun ted'thereon, the beater roll being shown mainly in conventional form.

Fig. II is "a detail transverse section on a line corresponding to line 2-2 of Fig. I.

Fig. III is a detail transverse section similar to Fig. II, with the parts in actuated position.

Fig. IV is a detail horizontal seotlon on a line corresponding to line H of F g. I.

Fig. 'V is .a vertical transverse section on a line corresponding to line 55 of Fig. V. Fig. VI is an enlarged detail section on a line corresponding toline 6-6 of Fig. V. i Fig. VII is a side elevation of one of the filler bars as they are commonly constructed. Fig. VIII is a side elevation of one of the beater bars.

In the drawing,similarreference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction ofqthe little arrows at the ends of the sectionlines.

lrepresents the shaft of the beater roll supported by bearings 2. The beater roll is shown mainly in conventional form and only such parts are illustrated as are deemed necessary to; illustrate my improvements.

" The beater roll, designated generally by the numeral 8, comprises spiders 4 carrying the iron beater bars 5 between which the filler bars are inserted. The opposed sides of-the bars 5are shaped so as to retain the filler b-arswhen inserted. This shape makes it necessary to exert considerable force on the filler bars in insertingthemand'it is this condition which frequently causes the injury or destruction of the fillerbars when driven to place by means of sledges, besides the large amount of labor required.

I provide a yoke-shaped frame comprising side members 7 and cross member 8. The cross member is preferably an I-beam as shown in Fig. V. The frame is of such di mensions that it is adapted to embrace the beater roll,with the side members 7 resting upon the beater roll shaft at each side of the beater roll, as shown in Fig. I. The

ends of the arms have seats 9 therein for the shafts. The U-shape-d tie-rods 10are adapted to embrace the shaft and their ends are disposed through cross pieces 11 mounted on the cross member 8 to receive them.

The, tie-rods are detachably secured by means of the nuts 12 threaded-upon the ends thereof. Cylinders 13 are mounted upon the cross member 8 of the frame so that when the frame is mounted upon the shaft of a beater roll the cylinders are supported ra-' d-ially of the beater roll. The cylinders are open at their inner ends so that the pistons or plungers 14: may be projected therefrom,

as shown in Fig. ill. The prcsser bar 1:) is supported to reciprotmte radially of the shaft 1. by means of the rods 16 which are arranged through the cross member 8 and connected. at their outer ends to the ends of the semi-elliptic springs 17 mounted on the cross member. This spring yields when the pistons are actuated but is of sutlicient tension to retract the prcsser bar and also return the pistons to their initial position. The presser bar is of such width as to pass between the beater bars 5 so that the inserts may be fully seated, see Fig. III. The presser bar has plates 18 secured thereto in alinement with the pistons.

The fluid may be supplied to the pistons under pressure by any suitable means but I find a satisfactory means to be a force pump de= gnated generally by the numeral 19 which is mounted on one of the side members T of the frame and connected by the pipe 20 with the outer ends of the cylinders so that a suitable fluid, such as oil, may be drawn from the storage tank 21 and forced into the cylinders. Suitable check valves 22 are provided in the pump connections to the cylinders. I also provide a return pipe which is connected with the storage tank 21 and with the outer ends of the cylinders. This pipe is controlled by the valve which is closed when it is desired to actuate the pistons but which is opened to relieve the pressure and allow the spring 17 to return the presscr bar and pistons to their normal position.

In operation the frame is mounted upon the shaft of a beater roll as shown .in Fig. I. The filler bar is positioned as shown in Fig. H, the valve 29 of the pump is operated to force the fluid into the cylinders thereby forcing the pistons downwardly and with them the presser bar. When the filler bar is forced to position the valve 2% opened, thereby releasing the pressure and permitting the spring 1? to return the presser bar and the pistons, displacing the fluid from the cylinders through the pipe connections T he beater roll is then rotated to bring another filler bar space to position and the operation repeated.

I have illustrated and described my improvements in the form in which I have embodied the same in practice. I have not attempted to describe various modifications and adaptations which I contemplate within the scope of the appended claims as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as operating and other conditions may render de sirable.
