IMPROVEMENT-IN PLANI-NG-MAClv-llNES.

Specification forming part of Letters Patent No. 167,749, dated September 14, 1875; application filed April 24, 1875.

To all whom it may concern:

, Be it known that we, WILLIAM H. DOANE and GEORGE W. PAssEL, both ofv Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improveniente in Planning-Machines, of which the following is a specification: v

This invention relates to that class of haut planing machines, so termed, although they are also used for grooving and gaining, in which the cutter-head operates between two separate tables, adjustable both vertically and horizontally independently of each other, so that they may be arranged either in the same plane or in different planes, according as the nature of the work to be done may require, while they may also be separated to a greater or less extent, to adapt the gap between them to cutter-heads of various diameters.

Our improvement consists, first, in providiu g one of the two tables with a slide, to be used in gaining or grooving for bridging thegap between the tables at one end ofthe cutter-head, so that the stick of timber may have a support at this end of the cutter-head as well as at the other end, where it is held in the gamer-frame.

Heretofore a third table has always been provided for this purpose in this class of machines, which not only makes them cumbersome, but also requires additional mechanism for affording the means of adjusting this third table. All this is avoided by the use of this Simple slide.

Second, in novel means for supporting and rendering adjustable the tables, which will be clearly explained in the ensuing description.

In the annexed drawings, Figure l is a perspective view of our improved machine. Fig. 2 is a transverse section thereof. Fig. 3 is a longitudinal section of the same. Fig. 4 is a bottom view of one of the tables, together with its supporting bracket and the guides for the latter. Fig. 5 is a perspective view, illustrating more particularly the fence and the manner of connecting it to the front table. The same letters of reference are used in all the 'Iigures in the designation of identical parts.

lly elevated above the central column.

. ently of the other.

' A refers to the column or stand of the machine, on the upper end of which suitable webs are formed to aord means for supporting the tables and cutter-spindle in a position proper- The spindle B, arranged horizontally across the machine, is, at one end, supported in a bearing, C, ixed or cast on the top of web A', and

at the other end in a removable bearing-block, D, the base of which, about on a line with the top of vcolumn A, has a couple of longitudinally-disposed ribs, d, fitting corresponding grooves in the bracket A2, cast upon or secured to the column A. Ihe bearing-block is secured to the bracket by a clamping-screw, E, which passes through a slot in the outer edge of the bracket into a tap in the base of the bearing-block, so that to remove the latter requires only a few turns of the screw to loosen its hold on the bracket.

rlhe seat of the bearing-block D is parallel to the axis of the cutter-spindle, so that it may be readily removed from and again slipped on the outer end of such spindle when it becomes necessary to substitute one cutterhead for another.

The cutter-head F is arranged between the tables Gr and H upon the spindle B, which is driven by a pulley, I, to impart the required rotary motion to the cutter-head, which is so secured on its spindle that it may be readily removed therefrom. Each table is supported upon a bracket, K, which is arranged in guides lc on the transverse web A3 of the stand or column A. The horizontal leaf of the brackets K lits a recess in the under side of the table it carries, and they are secured together by a set-screw, Kl, which passes through a longitudinal slot, k1, in the bracket into a nut or tap in the table. The tables may thus be adjusted horizontally to and from the cutterhead, so that their inner ends can always be arranged close to the path of the cutters. The brackets K are maintained at any required elevation in their guides by screws K2, which are supported in lugs on the webs A3, and work in nuts k2 fixed on the brackets. Of course each table may be adjusted independ- In planing stuff the surface of the rear table H will be arranged in the same plane in which the highest point that the bits reach is located, and the front table G will be adjusted such a distance below this plane that the cutters will remove the desired thickness of shaving from the stui', which is thus firmly supported, both in front and rear of the cutters, upon the two tables, being pushed from the lower onto the at such times. is to be slid into the recess Lz in table G, thus bridging the gap between the tables, and doing away with the necessity of a third table. The fence or guide M is connected tothe front table G, having a slotted laterally-projecting arm, g, which aiords the means forsecuring it to the table by means of a bolt or screw, g1. It reaches beyond the gap, and overhangs the rear table, its lower ed ge-being cut away, .as at g2, so that the rear table can be properly elevated above the front" table without interfering 4with the guide or fence attached thereto.

The fence can be readily adjusted, and may be easily removed when the machine is to be used for gaining stuff. A

We do not here claim the use of the axiallyremovable bearing-block I), as we intend to cover this feature in a separate patent.

What we claim as our invention, and desire to secure by LettcrsPatent, is- 1. The combination of table H, slide L1 fit ted in a longitudinal groove therein, and table G, having a recess, L2, in the end adjacent to table H, substantially as and for the purpose specified.

2. The combination of table G or H, slotted bracket K k1, guides k k, screw K1, nut k2, and

screw K, substantially as and for the pur-4 poses speciied.

In testimonylwhereof wehave signed our naines to the foregoing specification in the presence of two subscribing witnesses.
