To all whom it may concern:
Be it known that I, ANDREW N. GABRIELSON, a citizen of the United States, residing at Mount Iron, in the county of St. Louis, State of Minnesota, have invented certain new and useful Improvements in Planes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to planes, and more particularly to hand-planes, and has for its object to provide a plane which may be used either as a jack-plane or a smoothing-plane and which will be provided with guides arranged for movement into and out of position to lie against the working face of the board to insure even planing of the edges thereof.
Other objects and advantages will be apparent from the following description.
In the drawings forrning a portion of this specification, and in which like numerals of reference indicate similar parts in both views, Figure 1 is a side elevation of the present plane with the guides in the rabbets and showing them in lowered position in dotted lines. Fig. 2 is a transverse section on line 2 2 of Fig. 1, the guides being lowered.
Referring now to the drawings, the present invention comprises a body 5 and bits 6, provided with the usual bit-adjusting mechanism 7. The body 5 has longitudinal rabbets 5′ at its lower side angles, and communicating with each of these rabbets there are forward and rearward vertical threaded passages 8, in which are adjustably engaged set-screws 9, the lower ends of the set-screws being revolubly engaged in guides 10, which extend longitudinally of the body 5 and which are adapted to lie in the rabbets 5’. The arrangement is such that the set-screws may be operated to move the guides 10 into and out of the rabbets, and when both guides are in the rabbets the plane may be used in the ordinary manner. When the edge of a board is to be planed, one of the guides is lowered to rest against the working face of the board, and thus planing of the edge at right angles to the working face is assured.
Laterally-extending threaded passages 11 communicate with the passages 8 and open through the side faces of the body, and in these passages 11 there are engaged screws 12, which are operable to impinge against the set-screws 9 to hold the latter, with the guides, at different points of their movement. In their mutually-adjacent faces the guides have recesses 13, which receive the edge portions of the bit 6 when the guides are in the rabbets.
What is claimed is —
In a plane, the combination with a body having longitudinal rabbets at its lower side angles and having vertical threaded passages communicating with the rabbets, of set-screws engaged in the passages, guides connected with the lower ends of the set-screws for rotation of the latter with respect thereto, said set-screws being operable to move the guides into and out of the rabbets, and means for holding the set-screws with the guides at different points of their movement.
In testimony whereof I affix my signature in presence of two witnesses.
ANDREW N. GABRIELSON.
