PLANER.

` SPECIFICATION forming part of Letters Patent N0. 771,817, dated October 11, 1904.

Application led March 18, 1903. Serial No. 148,339. (No model.)

T0 all whom, t may concern:

Be it known that I, MARK FLATHER, of Nashua, county of Hillsboro, and State of New Hampshire, have invented certain new and useful Improvements in Planers, of which the following is a specification.

My invention relates more particularly to metal-planers, and has for one of its objects so to arrange the housings of the planer that one of them may be moved backward, so as to leave one side of the planer open for the purpose of planing crosswise of long sections of material.

Another objectof my invention is to arrange the housings in such manner as to properly support the cross-rail by an extension between same and the housing, which is arranged to be moved backwarc.

Still another object is to so construct and arrange the vertical feed mechanism as to make it automatically adjustable to the different positions of the housings. Y

A further object of my invention is to provide for raising and lowering the cross-rail -by means of a counter-shaft capable of being driven in opposite directions by belts secured to the cross-tie of the housings.

@ther objects of Amy invention will more clearly appear from the description and the drawings accompanying this specification.

In the drawings, Figure l is a front elevation of a metal-planer embodying my invention. Fig. 2 represents a side elevation of samewith the parts arranged as an open side planer. Fig. 3 is a plan view of same and arranged as an open-side planer. Fig. L is a sectional View through line X X, Fig. 3, of a portion of the vertical feed mechanism for moving' the cross-rail up and down.

In the drawings, A represents the bed of the planer, and A an extension of the bed adapted to support the adjustable housing and the supplemental work-table.

B is the platen or work-table and is longitudinally movable in ways A2 A2 in the upper face of the bed A.

B is a supplemental table movable in the same direction as the main work-table B and is used to support long pieces of material being operated upon when the planer is used as an open-side planer.

C is one of the housings of the planer and is permanently attached to the bed A.

C is the adjustable or movable housing and is attached to the extension A in such manner as to be longitudinally adjustable thereon and is provided with the adjusting mechanism, which consists of the pinion d, attached to the shaft c, and a ratchet-handle CZ', attached to the upper portion of said shaft, the shaft c being mounted in bearings attached to the housing C.

A rack e is attached to the extension A and is adapted to enmesh with the gear d.

c is a pin which is inserted in holes in the extension A and the foot of the housing C. Said holes are arranged to register when the said housing C is in proper position to be used either as a standard planer or an open-side planer.

The bolts c2 are used to clamp the housing C in its adjusted position.

D is a cross-rail of the usual construction adapted to support the tool-carrying heads D D.

E is the cross-tie adapted and arranged to securely fasten the tops of the housings C and C and is permanently attached to the housing C and adjustably secured to the housing C.

When the planer is used as an open-side planer, there is inserted between the cross-rail D and the housing C the extension-piece F. This extension-piece F is 4so formed at its outer end as to be readily secured to the crossrail D and at its inner end to be adjustably secured to the housing C' in such manner as to be raised and lowered thereon by the adjusting-screw G, which is threaded throughout its length and is adapted to revolve in the threaded bearing g, attached to the extensionpiece F by the bolt g. The extension-piece F is adjustably held to the housingC' by the gib f, attached thereto by the' gib-screws fff.

G is a vertical adjusting-screw for vertically adjusting the end of the cross-rail D opposite to that attached to the extensionpiece F.

Referring to Fig. 3, we Eind the vertical adjusting-screws G G are operated by means of a counter-shaft H, mounted on the upper face IOO of the cross-tie E by suitable bearings. l This counter-shaft H has mounted upon it pulleys 7L and 7L, driven in opposite directions by means of a straight and a cross belt, as illustrated in Figs. l and2. The pulleys /1/ and /f are normally loose upon the shaft H and are secured thereto when it is desired to turn said shaft H by friction-clutches operated by the shipper-rod /zf through the medium of the lever /b and clutch-operating parts and /f.

The vertical adjusting-screws G are revolved by the counter-shaft H in either direction, according as it is desired to raise or lower the cross-rail D, this through the medium of the bevel-gear ce, which enmeshes with the gear a8. Said gear a is secured to the hub of the gear a and revolves same. The gear a emneshes with the gears a2 and b, mounted upon the shafts a3 and b, respectively. At the outer end of the shaft a3 is a bearing at, which supports it. There is also mounted thereon the gear a5, which enmeshes with the bevel-gear ca attached to the vertical adjusting-screw G. This shaft ufl has a fixed bearing' a7 at its inboard end, in which said shaft revolves. The shaft is supported at its inner end by an adjustable bearing b2, having an inward extension provided with a bearing which surrounds the hub of the bevelgear a. The bearing is also supported by the turn table 3. The outer end of said shaft is supported by the bearing b4, which has an inwardly-extending lug surrounding the hub of the bevel-gear b, that is attached to the upper end of the vertical adjusting'- screw (1. The bearing /l is also supported upon the turn-table 07. The horizontal shaft is secured in the be\f*elgear s by a key in said shaft 71 in such manner that said shaft will freely slide through the gear /f longitudinally, but is rotatively immovable thereon.

The object of the arrangement of the shaft and its bearings b2 and 1 is that they will turn upon the hubs of the gears a and L and automatically adjust themselves to the different positions of the housing' C when it is adjusted to the position it will occupy either as a standard planer or an open-side planer. Furthermore, the arrangement of the frictiondriven counter-shaft H is such that by manipulating the lever It* the cross-rail may be moved up or down, as the case may be, by means of belts driven from any convenient power-driven shafting.

J is a supporting device which is adjustably attached to the cross-tie E by means of the bolt J', its lower end being attached to the extension-piece F. The object of this supporting device is to firmly tie said eXtension-piece F and the cross-tie E together in such manner as to more lirmly support the cross-rail D when the tools mounted on the tool-blocks thereon are performing the operation of planing.

The operation of my improved planing-machine is as follows: Assuming the planer to be adjusted to be used as a standard planer, in such case the movable housing C will be moved forward to the position represented in dotted lines in Fig. 3, the vertical adjustingshaft will assume the position shown in dotted lines `in said Fig. 3, the bearings b2 and if* will revolve on the hubs of the gears a and Z2, respectively, upon the turn-tables b3 and 117 and assume their proper position. The planer as constructed when the adjusting-block F is removed and the housing C moved forward and the cross-rail secured to it is operatively and in appearance astandard planer. When it is desired to plane a long piece of material crosswise of its greatest length, the housing C is moved backward to the position shown in Figs. 2 and 3. The extension-piece is then inserted and firmly secured to the cross-rail D at its outer end, and its inboard end is adjustably attached to the housing C by means of the gib f and the gib-screwsf. Then said extension-piece F may be adjusted vertically on the housing C by the described vertical adjusting mechanism. To move the housing C backward in the open-side position, the pin c is removed, the clamping-bolts 02 loosened, and the housing moved backward by means of the adjusting-shaft c, its ratchet-handle a7, the gear d, and the rack e, with which said gear enmeshes. When the housing C/ is moved back to its rearward position, long work may then be clamped to the platen B and the supplemental supporting-table BQ so that it will freely pass under the extension-piece F of the cross-rail D, as will be readily seen.

Having described my invention, what I claim isl.
