UNITED STATES JOSEPH DIXON, OF NEW YORK, N. Y.

IMPROVEMENT IN PLANING-MACHINES.

Specification forming part of Letters Patent No. 54,511, dated May 8, 1866.

lo all whom it may concern:

Be it known that l, JOSEPH DIXON, of 761 Second avenue, in the city, county, andState of New York, have invented 'a new' and Improved Matchin gAttachmen t for Plauers 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a front view, and Fig. 2 is a side view, ot' my improved attachment.

Similar letters of reference indicate like parts.

This invention relates to an improved method or device for regulating the vertical 'set of tonguing and grooving attachments in planing-machines, and which gives several desirable advantages over the present devices used for that purpose. A

My invention consists iu fixing the knifeholding head rigidly to its shaft and supporting the shaft on au adjustable or sliding bedplate, so that the adjustment of the knives or cutters may be made expeditiously and While the machine is in full motion by adjusting the said bed-plate, and which also admits of securing the knife-holding head to its shaft in a iXed manner, so as to be beyond liability of displacement bycncountering knots, 8vo., and, further, allows the matchingknives to be promptly removed out ot" the way when the planer is to be used for surfacing by dropping them below the surface of the planing-bed.

Having described the nature of my invention, I will proceed to describe its construct-ion and operation. V

The main bed D D, Fig. 2, ot' the atta' hment is secured to the side of the planer so as not to project above the surface ot the planing-bed by a set-screw which passes through the nut P, and the attachment is adjusted lat erally for different widths of boards by the said screw and nut P, the foot Q, sliding on a guide when such lateral adjustment is made.

D D is the main bed of the attachment, and

fixed to its shaft B B. The shaft B is supported on the adjustable bed-plate E by the standards e c. C is a belt-pulley by which the cutter-shaft B is driven.

The vertical adjustment of the knives is made or eected hy a screw, l, which is held by a collarin a iixed standard, J, and engages with a stud, H, which projects from the sliding bed-plate, and is operated by the gears K L and crank l.

The adjustablebed-plate E, Fig. l, is provided with an index or pointer, g, which travels over the face of a fixed graduated plate, f, and indicates the vertical set or position of the cutters ct a.

n m, Fig. 2, is a set-screw for clamping the adjustable bed-plate E firmly in position, and occupies a slot, o, in the plate E. By these means the vertical set of the cutters is easily regulated for different thicknesses of stuff or boards without stopping the machine, andthe cutters are held to their work in a reliable manner, displacement of the same heilig impossible without breaking of parts.

When the planer is to be used for surfacing orplaning only the cutter-head A is run down by the crank l, so as to be dropped below the surface ot' the planing-bed.

Having thus described my invention, Iclaim as new and desire to secure by Letters Pateut- The combination ot' cutter-head A, shaft B, adjustable bed E, indicator g f, and adjustingscrew I, substantially iu the manner and for the purpose set forth.

The above specification ot' my invention signed by me this 2d day of December, 1865.

JOSEPH DIXON.
