DOUBLE OR SECTIONAL PLANlNG-MACHINE. I

SPECIFICATION forming part of Letters Patent No. 542,598, dated July 9, 1895.

Application filed February 2, 1892.

To all whom it may concern.-

Be it known that I, LOUIS T. Pvo'rr, a citizen of the United States, residing at Ardmore, Montgomery county, in the State of Pennsylvania, have invented certain new and useful Improvements in Double or Sectional Planing-lvlachines, of which the following is a full, clear, and exact description; reference being had to theaccompanying drawings, forming a part of this specification.

My invention relates to double or sectional planing-machines; and it consists, first, in improvements in the mounting and actuating mechanism of the entry-feed or pressure rolls; second, in mechanism combined with the feed or pressure roll devices, so that the latter may be raised quickly by a foot-treadle actuated by the weight of the operator when an excessive thickness of material is presented; third, in lever mechanism operated by the hand, combined with the feeding-in table to lower the latter when desired and adapt the machine to irregularly-fed stuff. 1

The object of the first part of my invention is to obtain an effective means of driving or conveying power to the entry-feed or pressure rolls and of so mounting the same that each section of the roll shall have an effective and independent action under varying thicknesses of the material being planed, as well as a combined action through the single cross-head or mounting, in which all the upper rolls on each side of the planer are placed and supported.

In the accompanying drawings, illustrating my invention, Figure 1 is a side view of the forward or feeding-in end of a double or sectional planing-machine, showing so much thereof as is necessary to illustrate my invention. Fig. 2 is a plan view thereof. Fig. 3 is a sectional view of part of the upper rollsupport through the line 1 2 of Fig. 2. Fig.-- 4 is a section on the line 5 f Fig. 1. Fig. 5

is an elevation of the lifting screw-rod shown in Fig. 1. Fig. 6 is a section on the line 3 4 of Fig. 1; and Figs. 7 and 8 are elevations of detached parts shown in Fig. 2, the former of the side bracket or its shaft on which the feedrolls are mounted and the latter the bracket on which the free end of the rolls is supported. Fig. 9 is a vertical cross-section taken later- Serial No. 420,118. (No model.)

rolls and the bearings therefor pivotally mounted on theconnecting-bar of the crossheads, the equalizing-bar connecting the op posite spring-rods or resilient bearings for the cross-heads, and the guiding-recesses therein, in and by which the pivotal bearings of the entry-feed rolls are guided in any vertical reciprocation thereof which may take place from pressure of entering material, the upper part of the cross-head being broken away to show the feed-roll bearings more clearly; and Fig. 13 is a front view of the upper part of the same.

The feeding-in or pressure rollers are mouuted as follows: A single vertical guideway or housing R is placed on each side of the planer. A cross-head F, sliding in this guide, is mounted upon a vertical bar G, (see Figs. 1 and 5,)

having a screw-threaded lower end which is secured to a lever-arm G in the frame of the machine, and which carries a pressure-weight G The upper feed-rolls E E have their bearings indirectly in the said cross-head F, as hereinafter described,and are thus moved up and down with said cross-head by means of the bar G, counterbalanced by the weighted lever-arm G. Said cross-head F is provided with extension-plates F F vertically recessed, and through which passes a small shaft I-I, carrying an outwardly-pressing spring h", the top of which bears against the under side of the extension-plate F A swinging-arm h atfords a movable bearing for a shaft 7L carrying the upper feeding-in rolls E E. This swing-arm h is bolted at it (see Figs. 1 and 3) to a connecting-arm X which is pivotally mounted upon a tubular cross bar or tie X, which serves to tie or connect together the opposite sides of the cross-head on each side rests by its free end upon the extension-piece "X (see Fig. 9,) which is-recessed-at-.X ,--(see I :the .press u-reof en teringimaterial isremoved) F of the cross-head F to support it, or rather to hold it, and the roll E from droppingdown. The swing-arm h, which, as before described, is the bearing for the roll E, being thus secured to the pivotally-mounted arm X is free to move up and down as pressure of entering material bears up against the roll E. The entering material causes this roll and its bearof rods H, and this bar X is guided in itsreciprocation by means .of alugn-or projection Fig.3) the edgeofthe.barXuocc-upyingat-his recess.

The main shaft M communicates therewith through the c0ggearing on wheel S.

The feeding-in table A is adapted to be raised when feeding in irregular-shaped stuff, and for this a handlever L is provided,

-mounted on a'trunnion A in the frame A of the machine, and bearing against the under .side ofthe feeding-in table.

'Having thus described my invention, what I-claim as'new, and desire to secure by Letters Patent, is-

1. In a sectional or double planing machine,

'- avertical guide way. on each side of the ma- "chine, a cross-head adapted to slide vertically therein, vertical lifting .rods von which 'the :cross head is'amounted,-;-Weighted levers to whichtheifree endsrofi said :rods are attached, upperwentry -.feed.ro.lls constructed in .sec-

tions; each havingindependent driving bear- ,ingspivotally mounted;,upon-the cross-head,
