IMPROVEMENT IN PiLANING-MACHI NES.

Specification forming part of Letters Patent N0. 201,624, dated March 26, 1878; applicat-ionfiled I May 19,1875.

To all whom it may concern: 1

Be .it known that I, WILLIAM R. NoRRis,

provements in Machines forPlaning and Sandpapering Doors and other frame-work of like construction, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings, making a part of the same.

- This invention is more especially designed for planing and smoothing doors; and it consists in certain novel means and combinations of parts, whereby the operations of planing the doors, of sandpapering the same, and of cutting the wedges from the lateral edges of the same are performed with great rapidity and accuracy, and much more cheaply than by the means or mechanism previously in use.

The machine is fully illustrated by the drawings, of which Figure 1 is a top view of the entire machine; Figs. 2 and 3, opposite side elevations of the same; Fig. 4, arear end view thereof; Fig. 5, atop view, representing a modilied construction; Fig. 6, a longitudinal vertical section of the construction shown in Fig. 5; and Fig. 7, a transverse vertical section.

Like letters designate corresponding parts in all the figures.

In the drawings, A represents the frame of the machine; B B, the two oblique cutterheads; 0 G, the lower and upper beds, which support and hold the door while it is being planed; D D, horizontal feed-rolls; d (1 cl d, four vertical feedshafts, bearing fluted heads; FF, upper and lower frames, bearingthe sandpapering disks; G, a drum on a vertical shaft for driving both sets of the sand-paper disks 9 g g y g g g g,- H H, two pulleys, to be conneoted by a belt, for transmitting motion from the driving-shaft to shaft of the drum G; II,two pulleys, connected by a belt, for transmitting motion from the driving-shaft to the upper cutter-head B; K K, two pulleys, connected by a belt, for transmitting motion from the drivingshaft to the wedge-trimming saws a a; L L L L pulleys, connected by a belt, for transit mitting motion from the driving-shaft to the under cutter-head B; M, the main pulley on the driving-shaft, by which the power is applied to the Whole machine; F P, upper and lower guide-plates, placed between the feedrolls and cutter-head, to guide and keep in horizontal position articles passing from the rolls to the cutter-heads; R, a movable guide, to direct the door or other article properly between the saws a c,- S, a stationary edgeguide, to keep the door in position between the said saws; VV, vertically-adjustable supports on the sides of the frame, to which is attached the upper bed 0, and on which the cutterhead B has its bearings.

In addition to, or insteadof, the horizontal feed-rolls D D, I employ. the four vertical feed-shafts and heads 11 d d d, the two former being stationary at one side, while the two latter are movable and laterally adjustable, that they may be made to work against the edges of different widths of doors.

These rolls Working upon the edges of the doors prevent their working sidewise, as there is a tendency to do on account of the oblique action of the knives of the cutter-heads, while at the same time they propel the doors forward, and thus very materially reduce the pressure it is necessary to apply to the sur faces of the door at the horizontal feederolls D D, and thereby entirely obviate the compression of the timber, which is very injurious.

To give positive and equal motions to these vertical feed-shafts, they are connected with the main driving-shaft at the front of the machine by means of shafts properly located,

and provided with suitable bevel-cog wheels,

as shown, or other equivalent means.

In order to communicate motion freely to the oblique cutter-head B from the shaft of the pulley I, which is at right angles to the frame; I employ a suitable flexible or universal-joint connection or coupling between their two shafts.

In the drawings, a device consisting of disks or cranks b b on the respective shafts, and connected by a flexible spiral rod or coile spring, 0, is represented.

The cutterhead B receives its motion through a single belt passing from the pulley L on the driving-shaft around the guide-pulleys L L suitably located on the frame, as shown in Fig.3, and thence around. the pulley L on the end of the cutter-head. This arrangement may be used as a substitute for the universal-joint connection, as above described.

The lower bed 0 0 consists of two plates, one on the front and one on the rear side of the cutter-head B, and quite close to it. plate in the rear is made to be adjusted vertically, to bring it into proper position to serve as a rigid support of the door, after it has been planed by the under cutters and while the upper surface is being borne upon by the Said upper bed 0 is made to be adjusted to suit the different thicknesses.

upper bed 0.

to be planed, and is secured to the frames V V with the bearings of the upper cutter-head B, with which it rises and lowers when different thicknesses are to be planed.

The guide-plates P P occupy the space between the feed-rolls and cutter-heads, and serve to keep the articles in proper horizontal position while passing from the feed-rolls to the cutter-heads. The upper plate 1? is vertically adjustable, that different thicknesses of articles may pass between it and the lower plate 1?, which latter may be stationary.

The wedge-trimming saws a a may be on one single shaft, as shown in Fig. 1, or on separate arbors, as shown in Figs. 5 and 7, one

or both being adjustable, to bring them into proper position to trim the wedges from doors 1 of different widths. In Fig.1 the saw a is shown as adjustable on its shaft, while in Figs. 5 and 7 the arbor upon which the saw a is secured can be extended inwardly by loosening the set-screw that confines the pulley to it.

The upper set of sandpapering-disks y 9 g are mounted in a vertically-adjustable frame, F, in a zigzag position, or in two lines, as represented, so that they may cover the entire surface of the article during its passage under The them. They are revolved by means of a belt passing around the pulleys f f on their respective shafts above the frame F, and also around the drum G, as shown in Fig. 1. The lower disks g g, mounted in the frame F, may be revolved in a similar way by belt and pulleys, but are represented as caused to revolve by frictional contact at their peripheries from one to another, the one next to the drum G being revolved by contact with it.

Although the oblique cutter-heads are represented as parallel, and one nearly over the other, I do not confine my invention to this arrangement. One cutter-head may be oblique in the opposite direction, as, for instance, crossing -like the letter X; and one need not be placed over the other, nor their degree of obliquity be the same.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the cutting cylinder, a flat revolving san'dpapering-surface, and suitable feeding mechanism to carry the work to both simultaneously, substantially as and forthe purpose herein set forth.

2. In combination with the oblique cutterheads B B, vertical feed rolls acting upon the edges of the door or other article, substantially as and for the purpose herein specified.

3. The combination of saws a a and guides R S, arranged in a planing-machine, and operating substantially as and for the purpose herein specified.

4. The revolving sandpaperingdisks g g g g, in combination with the feeding device of a planing-machine, substantially as herein specified.
