METAL-PLANING MACHINE.

Specification of Letters Patent.

Application filed August 19, 1903- Patented June 12, 1906. Serial No. 170,094.

To all whom it may concern:

Be it known that I, HANSON ROBINSON, a citizen of the United States, residing at Hanover, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Metal-Planing Machines, of which the following is a specification.

This invention pertains to metal-planing machines, and more particularly to that class known to the trade as open-side planers. Such machines comprise, in addition to the usual base or bed and sliding work-table traveling thereon, a column or standard located at one side of the bed and work-table and provided with vertical guides or ways, upon which is mounted an L-shaped beam or tool-head support, the depending portion which gives to the beam its L shape being for the purpose of affording a longer guiding and supporting member than would be afforded by the vertical measurement of the beam alone.

The present invention consists in mounting upon the depending or guiding portion of the beam a supplemental beam capable of being swung in a vertical plane through a greater or less number of degrees and in turn carrying a secondary tool-head.

It further consists in a novel arrangement of gearing or transmitting devices whereby the secondary tool-head maybe adjusted upon and relatively to its beam or support.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the, column and beam with the supplemental beam and the tool-heads above mentioned, a portion only of the column being shown,- Fig. 2, a section through the supplemental beam and guiding portion of the main beam, taken on the line 2 2 of Fig. 1; Fig. 3, a section on the line 3 3 of Fig. 1; Figs. 4 and 5, perspective views of the guiding portion of the main beam and the supplemental beam,'the latter detached from the former and turned face outward to better show its construction.

- The general type of planer here referred tothat is to say, an open-side planer-is well known, and it has the advantage over a twocolumn planer in that work may be placed upon and removed from the table from one side regardless of the position of the table and Without interference by any column or support at that side of the machine from which the work is handled. It is, however, desirable to operate simultaneously upon different faces of the body carried by the table, and for this reason a secondary tool-head has been mounted upon the depending or guiding portion of the beam. The range of movement and adjustment of such secondary tool-head has, however, been somewhat restricted, so much so as to limit its utility.

The purpose of the present invention is to increase the range of movement and facilitate the adjustment of the secondary toolhead. l/Vith this object in view the support is constructed as follows:

A indicates the usual main base or bed, and B the traveling work-table, which latter is reciprocated by suitable mechanism in a manner common and well understood, and hence unnecessary to be herein described. At one side of the main bed and table is located a column or standard O, which is of solid and substantial construction and suitably stiffened and braced to give it great rigidity, a precaution peculiarly necessary because of the long leverage which the overhanging beam has when carrying a tool at considerable distance from the column or standard and especially when a heavy cut is being made;

One face of the column or standard at a right angle to the direction of travel of the work-table and preferably truly vertical is formed or provided with a guiding-rib a of dovetail form in cross-section, its ofiice being to receive and guide the sustaining portion 1) of the beam D, which, as shown in Fig. 1, is of L shape. The guides may be of any usual form and will advisably, though not necessarily, be provided with the usual gibs and take-up screws. This, however, is a mere matter of detail in no manner involved in the present invention, hence unnecessary to be elaborated.

Upon the horizontal portion of the beam D is mounted on suitable guides or Ways a tool-head E, designed to traverse the beam from end to end, for which purpose a traverse-sorew' F is provided. The tool-head E is of common form and will in practice be furnished with the usual tool-stock and this in turn with such tool as the nature of the work in hand may require. A rod G, suitably splined or feathered, is journaled in the beam D, parallel with the screw F, to trav erse the tool head or stock in a manner com mon in this class of machines. So, too, the usual screw mechanism is or will be provided for raising and lowering the beam D bodily and holding it at any desired elevation. These and other matters not involved in the present invention are omitted as unnecessary to the present description. The depending portion I) of beam D is advisably widened out at or about its mid-height to form a turntable 0, suitably recessed to receive a neck or collar of on a supplemental beam H.

The turn-table is provided with an underout or dovetailed groove or slot 6, concentric with the axis of turn-table c, and designed to receive a segmental supporting and bearing rib f on the rear or inner face of supplemental beam H. As this rib will in practice ordinarily constitute more than a semicircle, it is preferably made in sections and bolted or screwed fast to the beam H or is at least provided with removable end sections (one or more) to facilitate its introduction into the groove or slot 6, it being apparent that with the portion 1) of the main beam D and the supplemental beam H, made as shown in Figs. 4 and 5, a short segmental rib f, integral with said beam H, could be introduced into the groove 6 by swinging the beam to proper entering position and thence around to its permanent field of action. The annular rib f gives adequate support and stiffening effect to the supplemental beam, the relatively large radius of the turn-table contributing greatly to this end.- The neck or collar d serves, however, as the primary pivotal support for the beam, leaving the rib to give the greater support and stiffening effect necessary to produce the results desired in the operation of the machine.

The upper face of beam H is provided with guiding ribs or ways g, upon which is mounted and guided a secondary tool-head I of usual form and construction and designed, as is head E, to receive a tool-stock, which in turn will carry a suitable tool. The details of the toolhead, tool-stock, and tool clamping and adjusting devices are not here involved, and said parts are therefore intentionally omitted. Any well-known and suitable type of tool stock or holder, tool, and adjusting mechanism may be adopted.

J indicates a traverse-screw journaled at or near its ends in bearings in the supplemental beam H, preferably between the guideways 9 and below the outer face or plane thereof. The purpose of this screw is to effect a movement of the tool-head I lengthwise of the beam H, for which purpose the screw passes through an internally-threaded lug or nut h, formed upon or secured to the rear face of tool-head I, as best seen in Fig. 2, and as is customary in connection with tool-heads and tool-stocks in this class of machinery. Screw J carries at one end a small pinion t, which meshes with a similar pinion j, carried by a shaft K, journaled in bearings in the beam H and lying parallel with the screw J. At its inner end, which is close to the axis of turn-table c,'the shaft K is provided with a bevel-pinion k, which meshes with a like pinion Z, carried by a horizontal shaft m, having a common aXis with the turn-table c, neck or-collar d, groove e, and annular rib This arrangement, it will be seen, permits the beam H to be swung about the axis of its turn-table and also permits the rotation of screw J through the medium of shafts m K and the intermediate pinions in whatever position the beam may stand.

Shaft m carries at its inner end a second bevel-pinion n, which meshes with a pinion 0, carried by a shaft L, journaled in a bearing or support p, formed upon or secured to the depending member I) of main beam D, as shown in Figs. 1, 3, and 4. The turn-table c is provided with a channel or recess g to re ceive the shaft L, and, if deemed desirable, it may also support the same against springing or lateral movement, or, in other words, may form a bearing for said shaft. or outer end shaft L carries a pinion 1", which meshes with a pinion 8, carried by a shaft M, journaled in suitable bearings or supports on the depending portion 1) of beam D. Shaft M is preferably squared at its end to receive a hand-wheel, crank, or other device by which to turn it; but any other suitable means for rotating said shaft may be provided. Said shaft maintains a fixed position relatively to the beam D, and whatever the adjustment of the beams D and H rotation of said shaft M will cause a traverse of the toolhead I lengthwise on the beam H in one or the other direction accordingto the direction in which said shaft is rotated. Screw F and rod G will likewise be provided with any usual or convenient means for imparting rotation thereto.

Details not herein specifically described may be of usual construction and arrangement, and those that are described may be varied within the limits naturally suggesting themselves to the skilled mechanician, the invention consisting, broadly, in combining with the beam and usual tool-head of an open-side planer a supplemental beam adjustable in a vertical plane about a pivotaXis and carrying a tool-head capable of adjustment longitudinally of said supplemental beam. It will of course be understood that absolutely vertical position of the column or At its upper standard or of the guiding-face thereof is not essential, though in practice it is usual and deemedidesirable. Shaft M is supported in a bearing or bracket N, bolted fast to the beam H, as indicated in Figs. 2 and 3, the bearing being shown also in Fig. 5. This bearing is cut away, as illustrated in the lastmentioned figure, to give proper room for the movement of the pinions 7c and Z, but by using larger pinions the cutting away may be dispensed with. The construction shown is, however, deemed preferable; because of the lesser space required for the gearing. The guiding portion 12 may of course be carried above the beam D, if desired, the important point being that it shall be of sufficient length to give proper guidance and steadying effect and extend also to apoint where it mayproperly receive and carry the supplemental beam.

It will be noted that by reason of the supplemental beam being mounted upon a turntable carried by the depending guiding portion of the main overhanging beam I am enabled to carry the side tool-saddle to positions close to the under side of the main beam or remote therefrom and at varying distances from the main post or standard. In other words, it may be set high or low and near either side of the work-table at will, and this without disturbing the adjustment of the main beam or the tool-head and tool thereon. It will also be observed that the supplemental beam is wholly supported upon the one member and held by one device, therein differing from angling tool-head supports or ways carried at one end on the horizontal beam and at the other end on the post or standard. The supplemental beam gives the tool a range of adjustment which the common saddle cannot give. In other words, it gives a wide range of adjustment additional to that afforded by the saddle, which latter is retained.
