GUSTAV HEYMEIER, OF BREMEN, GERMANY.

PLANE FOR PLANING THE BOTTOMS 0F GROOVES IN MOLDINGS AND ORNAMENTAL WOOD-WORK.

SPECIFICATION forming part of Letters Patent No. 420,232, dated January 28, 1890.

' Application filed June 1, 1889. Serial No. 312,910. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAV HES'ZMEIER, sculptor, of Bremen, in the Free State of Bremen and German Empire, have invented 5 a new and useful Improvement in Planes for Planing the Bottoms of Grooves in Moldings and Ornamental \Vood-lVork, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to tools for planing the bottoms of grooves in moldings and ornamental wood-work, and has for its object to provide an effective tool for that purpose.

The invention consists in a plane of the r 5 character specified, constructed as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate :0 corresponding parts in all the figures.

2 5 Fig. 5 is a cross-section of one of the handles of the tool on the line C D of Figs. 1 and 2.

The invention consists of a frame a, preferably hollow, as shown, and made of metal, and constituting the central portion a and On the bottom of the frame a is centrally located a plate I), secured by screws 1) to the central portion a of frame a. The plate 19 is provided with an opening 6 through which projects a blade 0 extending 3 5 up through an opening I) in the top of frame a, the blade 0 being movable through the openings 12 and F9 The blade 0 is clamped in fixed position by means of a shield-plate f, also projecting through openings 11 and b 4': and a screw g, passing through a washer g,

a slot g in frame 0., over which the washer g extends, and a slot 0' in blade 0, and engages plate f. By means of this construction the plate f and blade 0 may be adjustably raised 4 5 and lowered and clamped in position. Within the central portion a is also located a vertical guide-piece e, projecting through an opening 6' in the plate I) and opening 6 in the top of frame a, and vertically adjustable by means of a' screw cl engaging the guide-piece e and extending through a slot d in frame a, and a washer d overlapping the slot d. The lower end of piece 6 projects in front of the projecting end of blade 0, is in the form of a tooth, and is made of bone or other suitable material.

The piece 6 prevents the blade 0 from cutting too deeply into the wood.

The depth of the cavity to be planed is determined by the length of the blade 0 projected beyond the plate 17.

The lower endof the plate f is formed with the rounded edge f, and when the bottom of a groove is to be planed the plate f is adj ustably lowered so as to bring its lower end down to the cutting-edge of the blade 0, and the shape of the curved bottom of the groove is thereby retained while the tool is planing the bottom of the groove.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent A tool for planing moldings, consisting of the frame a, with handles M, the removable plate I), with openings b e, the vertically-adjust-able curved shield-plate f, and the verti-.

cally-adjustable slotted blade 0, projecting through opening 17 the binding-screw g, extending through slotted blade 0 and engagin g plate f, and the vertically-adj ustable tooth e, projecting in front of the edge of blade 0, and having the adjusting-screw d extending through the slot d in frame a, and the overlapping Washer (1 substantially as shown and described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GUSTAV HEYMEIER.
