GEORGE SPIRE, OF BUFFALO, NEW YORK, ASSIGNOR OF ONE-HALF HlS RIGHT TO ANDREVV H. FRANK, OF SAME PLACE.

l IM PROVEMENT lN PLANlNG-MACHINES.

Specification forming part of .Letters Patent No. 162,'776, dated May 4, 1875 application filed February 19, 1875.

To all whom it may concern:

Be it known that I, GEORGE SPIRE, of the city of Buffalo, in the county of Erie and State of New York, have invented certain Improvements in Planing-Machines, of which the following is a specification:

My invention relates more particularly to the spindles or mandrels to which the matcherheads are secnred.

In planing machines, as ordinarily constructed, the upper ends of these spindles project above the bed on each side ot' the board being operated upon. When the full width of the machine i's required for planing wide boards without matching the same, these projecting spindles are in the way, and require to be lowered below the level of the bed. ln raising the spindles to their former position, (after having been so lowered,) it is Very difficnlt to bring them into their proper position for matching, and a great deal of time is necessarily spent in ad justing the same.

The object of my invention is to remedy this defect; and it consists of a spindle having its npper portion, which projects above the level of the bed, jointed to the main portion, so that the projecting portion can be readily swung down below the level of the bed, after removing the natcher-head, while the main portion of the spindle remains stationary, thereby avoidin g the necessity of frequent adjnstment of the spindles.

In the accompanying drawing, Figure lis a sectional elevation of a portion of a planin gmachine, showing my improved spindle with the matcher-head secured thereto. Fig. 2 is a similar View, showing the matcher-head removed and the projeoting portion of the spindle swung down below the level of the bed. Fig. 3 is a detached View, on an enlarged soale, of the upper portion of the spindle, with the matchcr-head secnred thereto. Fi g. 4 is a View of the upper end of the spindle, showing the projecting portion, swung down, in dotted lines. Fig. 5 is a plan View thereot'.

Like letters of reference designatelike parts in each of the figures.

A is the bed of a combined planing and matching machine; B B, the feed-rollers, and 0 the horizontal cntter-head. D represents the lower or main portion of one of the vertical matcher-spindles, and f f the bearings in which it turns. d represents the upper portion of the matcher-spindle, which, in its normal position, projects above the level of the bed A. The portion d ot' the spindle is jointed to the main portion D" thereof in such manner that it can be readily swung down into a horizontal position, or nearly so, when the entire upper portion of the spindle will be below the level ot' the bed A, as clearly shown in Fig. 2. As shown in the drawing, the portion d is connected to the portion D by a tenon, g, fitting in a mortise, g in the main portion"D, and held therein by a pin, 9 The end of the portion D and the tenon g are ronnded off on one side, as shown respectively at i and j, to permit the jointed portion to be. swung to one side only, while the opposite sides of the end ot' the portion D and the tenon g are forned square or rectangnlar, to arrest the movement of the portion d in the opposite direction when it has arrived in line with the main portion 1). H is the matcherhead, carrying the matching-tools Z, and secu'ed to the npper end of the spindle by a set-screw, 75, in the ordinary manner,` while it can be adjusted vertieally by a set-screw, lg'. The socket of the matcher-head is of such length as to receive, besides the jointed end d of the spindle, a sufficient length of the main portion thereof to form a rigid and reliable hearing, as clearly shown in Fig. 3.

When the matcher-head is applied to the spindle, the jointed portion d, being firmly clamped by the closely-fitting socket of the head, forms practically a rigid extension of the spindle, and aft'ords all the advantages of a long solid hearing. Upon removing the matcher-head from the spindle, the portion d is readily swung at right angles to the main portion D, so as to bring it below the level of the bed A, when the entire width of the Inachine is available for planing boards.

lVhen the matcher-heads are to be reapplied, the portion d is readily swung np to its normal position, and the matcher-head slipped ou and properly Secured in place.

As the spindles and their bearings are not disturbed during this operation, the frequent readjusting of the same, which requires so much time and attention in mailing-machines as heretofore construeted, is entirely obviated.

What I claim as my invention is- The oombination, with the bed and matcherhead of a planin g-machine, of the spindle D,

having its ppe' portion, d, which projects above the level of the bed, jointed to the main portion, sc as to be readily swung below the level of the bed when not required to be used, substantia-lly as hereinbefore set forth.
