JACOB P. BECK AND JOHN H. WEAVER, OF LOCK HAVEN, PA., ASSIGNORS OF ONE-THIRD THEIR RIGHT TO A. N. RAUB, OF SAME PLACE.
IMPROVEMENTIN MACHINESMFR SMOOTHING AND CRNERING PAN-ELS.
Specification forming part of Letters Patent No. 156,474, dated November 3, 1874; application led l August 22, 1874. l
-To all whom it may concern:
j resents a side velevation of our improved machine for smoothing and cornering panels; Fig. 2,atop view 5 and Fig. 3, avertical transverse section of the same on the line c c, Fig. 2.
Similar letters of reference indicate corresponding parts.
The object of our invention is to construct an improved machine for smoothing and cornering panels, so that the sandpapering of the raised part at one side thereof may be obtained, at the same time with the broad level portion at the other side, by mechanical means in place of the hand-work hitherto employed for this purpose.
Our invention consists of vertically-rotatin g heads or disks, With detachably-inserted pads, covered with sand-paper for smoothing` both sides of the panel, and of adjustable detachable bits for cornering the same. The revolving heads work on separate mandrcls, one being laterally adjustable to the thickness of the panel; the other being capable of vertical adjustment on an arc-shaped guidezsupport.
In the drawing, A represents a supportingframe ofonr improved panel smoothing and cornerin g machine 5 B,therevolvin g disks or heads,
`which are made of suitable metal, applied to separate mandrels C, and rotated, by belts and .pulleys from the driving-shaft, independently of each other. Pads B', of suitable shape, are set into corresponding recesses of the heads B, the sand-paper being stretchedover the same, and iirmly fastened by securing the pads, which arehin ged to the heads at one end,
and secured, by screws a, at the opposite end.
Detachable cutter-bits D are set into the heads in an adjustable manner by means of slots b and fastening-screws d, and serve for cornering or grooving the panels.` The bits D are removed whenever it is desired to smooth y the broad liat portion of the panel. One head B is made laterally adjustable on frame A by means of its mandrel-supporting bearing E, which is provided with lateral slots c, for the fastening-screws e', Fig'. 2, so that the whole bearing E maybe changed to the thickness of the panel by the set-screw f turningin a guide, f,.of frame A. The opposite head B is made adjustable, in vertical direction, by placing its mandrel-bearin g F on an arc-shaped guidesupport, F, on which the bearing F slides to any required height, by the action of the screwbolt g, applied to the lateral piece g1 of the bearing F, and turning in the perforated lateral top piece g2 of support F. The head B is thereby raised in the same plane, for the purpose of smoothing, by its wider reach, panels with larger surface at one side than at the other, for accomplishing the smoothing of unequal sides at the same time. The cutterbit has to be detached when such panels are passed through the heads. The guard-plate G for guiding the panels on their passage between the heads, is also laterally and vertically adjustable, by means ofslides and set-screws, so as to accommodate itself readily to the thickness of the panel and also to the raised head. The panels are thereby smoothed with greater facility and rapidity, at both sides, whether the surfaces ofthe same are of equal or unequal size. l
Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In panel smoothing and cornering machines, the combination of two vertical revolving disks or heads, being placed on separate mandrels, one being adjustable in lateral, the other in vertical, direction, for smoothing, at the same time, panel sides of differently-sized surfaces, substantiallyas specified.
2. rlhe revolving head B, having hinged sand-paper fastening-pads B', secured by setscrews a, as set forth.
