SECTIONAL FEED AND PRESSER ROLL.

SPECIFICATION forming part of Letters Patent No. 717,593, dated January 6, 1903. Application filed January 3, I898. Serial No. 665,375. (No model.)

To ctZZ when?, it may concern.;

Be it known that I, CHARLES J. L. MEYER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sectional Feedand Presser Rollers; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The main objects of my invention are to insure simultaneous and equal engagement of diiierent parts of a f eed or presser roller with a plurality of strips or pieces of material or with different parts of strips or pieces varying in thickness transversely and to simultaneously feed a plurality of stripsor pieces of lumber or other material of different or varying thicknesses to a plan er or other machine or to yieldingly hold them in the proper position to be operated upon by a planer-knife or other tool.

The invention consists, essentially', of a roller composed of sections movable separately and transversely on a common shaft through which rotary movement is imparted to the several sections and separately-yielding tension devices bearing upon the peripheries of the several sections, and of certain novel details in the construction and arrangement of component parts of the device hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several tigures.

Figure l is a vertical longitudinal section on the line l l, 2, of a portion of a planer to which my improved roller mechanism is applied. Fig. 2 is an end elevation of the machine as viewed from the left with reference to Fig. l. Fig. 3 is an enlarged vertical cross-section on the line 3 3, Fig. 2, of the roller mechanism. Fig. 4 is an axial section, on'a still larger scale, of a portion of one of the sectional rollers. Fig. 5 is a cross-section of one of the rollers, showing a modification of one of the tension devices employed there-v with. Fig. G is a cross-section of one of the roller-shafts and an end elevation of one of the roller-sections, showing a modified construction thereof. Fig. '7 is a side elevation, on an enlarged scale, of one of the tensioniollers, and Fig. 8 is asimilar view of a modified form thereof.

Referring to Figs. l and 2, A designates a portion of the frame of a planer provided with a work-supporting bed B. C designates the planer-knife, and D the lower feed-rollers, projecting on their upper sides slightly above the bed B through openings therein.

The foregoing parts are or may be of the usual construction and arrangement employed in this class of machines and are shown merely for the purpose of more clearly eX- plaining my improved roller mechanism, which may be applied to any machine in which a sectional feed or presser roller is desirable.

F. is a vertically-adjustable slide or frame supported and guided at the ends in standards F F on the Vmain frame A andprovided with bearings for a driving-shaft G, which extends horizontally over and across the bed B. The slide E is adjusted by vertical screws e, engaging therewith at or near the ends, and a horizontal crank-shaft e,which has bearings on the upper ends ofY the' standards F and is connected with' said screws by bevel-gears incased in boxes e2 and 'not shown, one end of the shaft e' beinOr s uared as shown in Fig.

2, to receive a crank or hand wheel.

II H are the roller-frames, formed with sleeves g, by meansof which they are pivotally mounted upon the shaft G. They are also formed or provided at their ends, as

shown in Figs. 2 and 4, with boxes g, which support the roller-shafts I parallel with the driving-shaft G, on opposite sides thereof. The roller-shafts I are connected at or near their ends with the driving-shaft G by gears it' and g2, as shown in Fig. l, and the driv ing-shaft G is provided at one end, as shown in Fig. 2, with a gear g3, through vwhich it is driven from any convenient part of the machine.

'Ihe feed or presser rollers are composed of sections .I J, loosely mounted upon the shafts I end to end and held in place thereon by nuts jj, as shown in Figs. 2 and 4t. The holes in the several roller-sections are made some what larger than the shafts I, so as to admit IOD of a limited radial movement of said sections on said shafts, each section being movable independently of the other sections. They are compelled to turn with said shafts by splines 77e", which loosely engage with notches in the bores of the roller-sections, as shown in Fig. 3, or in place of the splines the roller-shafts and the holes in the roller-sections may be made square, as shown in Fig. 6, or of any other shape that will permit the sections to move radially a limited distance, but will compel them to turn with said shafts.

K K are slides carried bythe roller-frames H above the sectional rollers and movable in said frames toward and from said rollers, the number and arrangement of said slides corresponding with the number and arrangement of the roller-sections J. These slides are held and guided in their proper relative positions between vertically-disposed faces on the roller-frames and bars or plates h, connected therewith by squared shoulderbolts h'.

L represents rollers which may be made double, as shown in Fig. 7, or single, as shown in Fig. 8, and are journaled parallel with the roller-shafts I in the slides K, so as to bear upon or against the peripheries of therollersections J. They are supported and held in their proper relations to each other by the squared shoulder-bolts 71,', as shown in Fig. 4. When the roller-sections J have transversely-corrugated faces, as shown in Fig. 3, they are also formed with circumferential grooves, as shown in Figs. 2 and 4, to receive and afford proper bearings for the peripheries of the rollers L.

The rollers L are yieldingly pressed and held against the roller-sections J by spiral springs M, interposed between the slides K, and adjusting-screws N, which are threaded in overhanging portions of the roller-frames H perpendicularly to the axes of said rollers.

The slides K, rollers L, springs M, and screws N constitute yielding and adjustable tension devices by which the several rollersections J are normally held in line with each other against theirshafts I opposite the bed B and the working faces of said roller-sections and by which said roller-sections are allowed to yield independently of each other away from the bed, so as to adapt themselves to and to insure their even engagement with strips of different thicknesses or stuff varying in thickness transversely, as illustrated in Fig. 4.

Each of the roller-frames H is adjustably and yieldingly connected with the slide E above the driving-shaft Gr by horizontallydisposed bolts or rods O, secured in said frames and passing loosely through a crosspiece of said slide, and by spiral springs P, interposed between said frames and crosspiece around said bolts, as shown in Fig. 3, so as to permit each 0f the sectional rollers to yield upwardly independently of the other. By means of the nuts on the bolts O the tension of the springs P may be adjusted, and the extent to which the rollers J are raised or lowered by such adjustment may be compensated for by lowering or raising the slide In place of the springs M and adjustingscrews N arms m, pivoted to the rollerframes H, so as to bear on the tension-roller slides K and provided with adjustable weights n, as shown in Fig. 5, may be substituted.

By means of the tension devices hereinbefore described any desired degree of pressure may be applied to the roller-sections J, and this pressure may be readily adjusted for any or all of the sections, as desired. This is a great advantage over those sectional feed and presser rollers in which the tension devices consist of springs placed inside of the roller-sections between them and the shaft on which they are mounted and in which there is no provision for adjusting the tension of the springs, and their strength is necessarily limited and apt to deteriorate.

For the purpose of holding a plurality of strips or pieces of material in the proper positions on the bed B to be engaged separately by the roller-sections J the bed is provided on the upper side, as shown in Figs. l and 2, with longitudinal guides or parting-strips bb, arranged in line with the divisions between the roller-sections J.

The corners of the roller-sections J are rounded or beveled, as shown most clearly in Fig. 4, to prevent breaking, gouging into, or marring the corners of strips or pieces of material with which the roller-sections would otherwise engage but slightly.

I do not wish to be understood as limiting myself in the application of my improved sectional roller to any particular machine, as it is applicable to any machine in which a sectional feed or presser roller is desirable. Neither do I wish to be understood as limiting myself to the details of construction and arrangement shown and described, as they may be variously modified within the spirit and intended scope of my invention.
