DISINTEGRATING-MAOHINE.

Specification of Letters Patent. Application filed April 5, 1913.

Patented Dec. 39, 1913. Serial No. 759,126.

To all whom it may concern:

Be it known that 1, ROBERT F. W. Rossnnne, a citizen of the United States, residing at East Helena, in the State of Montana, have invented certain new and useful Improvements in Disintegrating-Machines, of

'which the following is a specification.

My invention relates particularly to improvements in disintegrating and crushing machines for crushing rock, ore or similar substances, and relates particularly to machines in which the crushing is performed by rollers, which are yieldingly held in adjusted position with relation to each other, in order to crush the material to predetermined size.

he primary object of this invention is to provide means whereby the crushing rollers may be speedily adjusted to crush material to different sizes, without varying the resistance of the rollers to abnormal pressure.

The further be more fully set forth in one form of apparatus embodying my invention, which consists in the new and novel features of construction and after set forth and claimed.

Inthe accompanying 1 is a plan View of a disintegrator embodying my improvement. Fig. 2 represents a side elevation of the same. Fig. 3 is a detail view of the adjusting lever.

Referring to the particular mechanism shown in the accompanying drawings, the rollers 1, 2 are mounted in suitable bearings provided in the frame 3 and are rotated in any suitable manner, as by a pulley 4, which may be connected with a suitable source of power. The material is fed through a hopper 5 supported on the frame immediately above the rollers. One of said rollers, for example, the roller 1, is mounted in fixed bearings and the other roller 2 is mounted in bloclrs 6 movable on the guides 7 formed in the frame. A plurality of arms 8 are se cured to the shaft of said roller and are mounted in a cross bar 9. Said arms are adjustably held in said cross bar by means of nuts 10 secured upon the outer end of each arm. A spring 11 is mounted on each arm approximately a between said bar and a collar 12, formed in tegral with the arm.

The cross bar 9 is connected to a plurality of upright levers 14 by means of a plurality of adjustable links 15. Said levers are pivoted to brackets 16 rigidly secured to the objects of the invention will combination of parts herein-V drawings :Figure frame and are connected at or near their tops by a cross brace 17. The levers are held in position by a suitable locking frame 18 which comprises the side pieces 19, each having a plurality of corresponding notches at or hear their outer ends, said side pieces being connected together and held in permanent relation to each other by the cross brace 20. Said notches are adapted to engage with suitable extensions or cap screws 21 provided upon the levers. The side pieces of said frame rest in suitable recesses provided in the frame 3 of the machine, so as to hold the levers against displacement, said side pieces 19 being securely held in position with relation to the levers 14 by means of the cap screws 21 which have threaded engagement in the levers, the shanks of said screws being received in the notches provided in the pieces 19. i

In operation, the rollers are adjusted with relation to each other by moving the operating levers 14 toward or from their vertical positions, which actuates the transverse bar 9 and through it moves the arms 8 attached to the crushing roller 2, thus causing the bearings of said roller to move in their guides. After being adjusted the rollers are locked in position by means of the locking device, which is caused to be engaged with the cap screws 21 provided upon the levers. Vhile the normal distance between the rollers is thus established, it is obvious, however, that a slight yielding movement of the rollers with relation to each other, independent of the adjusting levers, is permitted by the tension springs 11 which are mounted on the arms between the collars 12 provided thereon and the transverse bar. The proper tension of these springs may be determined for all positions of the roller 2 and is not affected or modified in any way whatever by the adjustment of the rollers toward or away from each other by means of the adjusting lever. V

y means of this construction, a speedy and rapid adjustment of the rollers may be made to crush material of difierent predetermined sizes by releasing thelocking frame and actuating the adjusting levers. The locking frame and the levers form a truss that is extremely rigid, but permits of speedy adjustment. The tension springs, when once adjusted, are not disturbed in any way by the movement of the rollers toward and away from each other and both the locking device and the adjusting levers are connected together, so as to permit simultaneous operation with a minimum of effort.

Although I have shown and described one form of mechanism embodying my invention, it is obvious that various changes within the knowledge of those skilled in the art may be made without departing from the spirit of the invention, provided the means cable roller 111 its adjusted position, and

means connecting said lever to said bar and permitting of the adjustment of the bar with relation to the lever.

2. In a disintegrating machine, a pair of crushing rollers, movable bearings for one of said rollers, arms connected to said bearings, a bar arranged in parallel relation to the axis of said roller and adjustable upon said arms, spaced connecting levers, and means connecting the respective levers to said .bar adjacent its ends but permitting of the adjustment of said bar with respect to the levers.

3. In a disintegrating machine, a pair of crushing rollers, movable bearings for one of said rollers, a bar arranged in parallel relation to the aXis of the roller, armsconnected to the respective bearings and extending loosely through openings in the ends of-said bar, nuts threaded upon the arms bearing against said bar to adjust the same with relation to the roller, springs arranged upon said arms and tensioned by the bar, and means for locking theb-ar in its adjusted position. 1

4. In a disintegrating machine, a pair of crushing rollers, movable bearings for one of said rollers, arms connected to the respective bearings, springs arranged upon said arms, a bar longitudinally adjustable upon the arms to tension said springs, a pair of levers, members pivotally connected to one end of said levers,said members being loosely disposed through said bar, means for securing the bar in its adjusted position upon said members, and additional means I to lock the levers against movement and retain said bar in its adjusted position.

This specification signed and witnessed this 27 day of March A. D., 1913.
