ADJUSTABLE J OURNAL-BOX.

Specification of Letters Patent.

Patented Oct. 12, 1909.

Application filed February 24, 1908. Serial No. 417,290.

To all whom it may concern: I

Be it known that 1, PETER J. JonoKnN,

residing in Sheboygan Falls, in the countyof Sheboygan and State of Visconsin, have invented new and useful Improvements in Adjustable J ournal-Boxes, of which the fol lowing 1s a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in ad ustable journal boxes for wood-working machines and more particularly to that class known as planers.

The primary object of this invention is to provide means for adjusting and alining the cutter of a planer, or shafts of other machines.

A further object of the invention is to provide means for locking the cutter or shaft in its adjusted position.

Vith the above, and other objects, in view the invention consists of the devices and parts, or their equivalents, as hereinafter described.

In the accompanying drawing, in which like reference characters refer to corresponding parts throughout all of the views: Figure 1 is a transverse sectional view of a frag,

ment of a planer provided with the improved alining means; Fig. 2 is a front view: thereof, with parts in section; and Fig. 3 1s a detail in plan view of the alining means.

Referring to the drawing the numeral 5 indicates one of the side frames of a planer and 6 the rotatable cutter thereof. The frame is provided with bearing brackets 7 (only one being shown), integral therewith and extending forwardly and rearwardly of the front and rear portions respectively of said frame, and these bearing brackets are in will be raised, and when moved in the opposite direction, the journal boxes and the cutter journaled therein will be lowered, and by moving only one of the wedge blocks, the cutter may be properly alined with the surface upon which the material to be planed rests. The lower portions 13 of the wedge blocks are semicircular in cross section and fit in correspondingly semicircular depressions let in the brackets 7 so that the journal boxes will swing slightly when either end of the shaft is adjusted permit ting said journal boxesto always remain in alinement with the axis of the cutter in any position of adjustment.

The inclined surfaces of the wedge blocks and the inclined lower surfaces of journal blocks will remain in contact with each other in any position of adjustment so that said wedge blocks may be moved endwise to raise or lower the journal blocks and the cutter carried thereby. The semicircular depressions 14 are longer than the wedge blocks 11 to allow an endwise movement of said blocks in adjusting the height of the journal blocks, and in order to move said wedge blocks, adjusting bolts 15 threaded in the upwardly extending guide lugs 16 of the brackets 7 and bearing against the ends of the wedge blocks are provided whereby a very fine adjustment of the cutter may be made.

When the cutter is properly alined the journal blocks are securely fastened to the brackets by means of locking bolts 17 which pass through elongated openings 18 in the :brackets 7, through slots 19 in the wedge blocks 11 and are threaded into the lower portions of the journal blocks. The elongated openings 18 of the brackets permlt the bolts 17 swinging in a plane parallel with the axis of the cutter, and the lower surfaces 20 of the brackets are curved concentrically with the curve of the wedge blocks so that the journal blocks may be locked thereto at any angle of adjustment of the cutter. The slots 19 of the wedge blocks permit of the said blocks being moved endwise by means of the adjusting bolts 15 when the locking bolts 17 are loosened.

In order to provide fiat bearings for the heads of the locking bolts 17 washers 21 formed with lower flat surfaces and with their upper surfaces curved concentrically with the curve of the brackets are positioned between the bolt heads and the curved surfaces of the brackets, so that in adjusting the cutter the curved portions of the washers will slide and bear against the curved surfaces of the brackets, and the bolt heads will bear against the fiat portions of the washers.

The operation of alining or adjusting the cutter is as follows: The locking bolts are loosened and the adjusting screws are turned to move the wedge blocks to the right or left as desired to cause said wedge blocks to raise or lower the journal blocks between the guide lugs. In case it is desired to raise or lower only one of the j ournal blocks, the semicircular lower portions of the wedge blocks revolving slightly in the semicircular depressions formed in the brackets will permit the ournal blocks to swing in a line parallel with the axis of the cutter and prevent the cutter shaft binding in the journal boxes. When the cutter has been properly alined the boxes and wedge blocks are securely clamped and locked to the b ackets by means of the locking bolts. The elongated openings and the lower curved surfaces of the brackets and the washers provided with the curved and flat surfaces permit the locking bolts to swing with the wedge blocks and to be locked together in any position of adj ustment and without any tendency to disturb the axial alinement of the journal boxes with the cutter shaft. It is obvious that this means of adjusting and alining the shaft of a planer is also adapted to adjust and aline shafts of other machines and it is to be understood that the claims contemplate the use of the adjustment in machines of a character other than described.

From the foregoing description, it will be seen that the construction is very simple and inexpensive and the finest degree of adjustment is provided for.

This case constitutes a division with additions of my application for Letters Patent for improvements in wood working machines, filed August 30, 1907, and bearing Serial No. 390,74t2.

WVhat I claim as my invention is:

1. Means for adjusting and alining a shaft, comprising a frame provided with guide lugs and with semicircular depressions, vertically adjustable journal blocks provided with inclined lower surfaces mounted on said frame and positioned between the guide lugs, blocks provided with semicircular lower portions and with inclined upper surfaces located beneath the ournal blocks, the semicircular portions of the blocks being positioned in the semicircular depressions of the frame and the inclined upper surfaces engaging the inclined lower surfaces of the journal blocks, said blocks also provided with openings extending vertically therethrough, said frame beneath the semicircular depressions provided with surfaces concentric with said depressions and having openings extending vertically therethrough, screws threaded to the lugs for moving the blocks horizontally to adjust the journal blocks and the shaft vertically, and locking screws engaging the concentric surfaces and extending through the openings in the frame and also in the blocks and threaded to the journal blocksfor locking the said journal blocks and the other blocks to the frame in any position of adjustment.

2. Means for adjusting and alining a shaft, comprising a frame provided with openings, semicircular depressions and semicircular surfaces beneath the depressions and concentric therewith, adjustable journal blocks mounted on said frame, a shaft journaled in said blocks, wedge blocks provided with semicircular portions and with openings slidably positioned beneath the ournal blocks, the semicircular portions of the wedge blocks fitting in the semicircular depressions of the frame and constructed to have a partial rotation therein, means for sliding the wedge blocks horizontally to adjust the journal blocks and the shaft vertically, and means passing through the open ings in the wedge blocks and the frame and engagingthe ournal blocks and the concentric surfaces of the frame for locking the parts together in adjusted positions.
