To all whom it may concern:
Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.
My invention relates to improvements in planes and particularly to planes, in which cutters of various sizes and shapes may be interchangeably employed.
The object of the invention is to provide a construction in which interchanges of cutters may be effected readily and quickly and the operation of the same made reliable and efficient. I have also sought to employ as few parts as possible and to make the construction as economical as its large variety of functions make feasible.
The construction of my invention in the particular form as shown in the drawings consists of a main body portion and a relatively movable section between which the cutting-iron is secured and held in place. Adjustable and interchangeable sole portions are provided by means of which the plane may be guided and the cutting depth regulated with any form of cutting-iron. These adjustable sole portions also support and steady the plane-iron and permit the user to vary the size of the throat or opening in front of the cutting edge.
The details of construction will be more plainly seen on an inspection of the accompanying single sheet of drawings.
Figure 1 is a side elevation of a plane embodying the improvements of my invention. Fig. 2 is a front elevation of the same with the addition of adjustable auxiliary guide. Fig. 3 is a perspective view of a cutting-iron. Fig. 4 is a perspective view of the adjustable and interchangeable sole portions for employment with the plane of my invention.
1 indicates a main body or stock portion of the plane having a guide-blade 2.
3 is a handle which is conveniently provided.
4 is the plane-iron or cutter, which has its cutting edge formed to correspond with the outline of the work which it is desired to turn out.
5 is a suitable clamping-screw for securing the cutter in place.
6 is a screw for adjusting the cutting depth of the plane-iron.
7 and 8 are rods which extend from the body portion of the plane.
9 and 10 are screws for clamping in position.
11 is a sliding section which is upon the rods 7 and 8.
12 and 13 are thumb-screws for clamping the section in place at the distance desired from the main body portion.
14 and 15 are flanges to the front and rear of the throat of the plane which extend downward. The plane-iron when clamped in place is partially supported by the rear flange.
16 and 17 are portions of a sole which is provided to correspond with the shape of the cutter employed to limit the cutting depth and to guide and direct the plane in its operation. These sole portions are formed, preferably, of wood.
18 indicates two screws which take into the sole member 16 for clamping it to the forward flange 14. The flange is preferably provided with keyhole-openings, as shown, so that the sole portion may be removed without entirely removing the screws, it simply being necessary to loosen the screws, slide the sole forward, when the screws may be readily drawn through the enlarged portion. The rear flange 15 is provided with oppositely-positioned keyhole-openings, and the screws 19 coact therewith to clamp the rear sole portion 17 in position. Both of the sole portions may be adjusted front and rear, so as to vary the size of the throat in front of the cutter to bring the rear sole portion up so as to reinforce the cutter and prevent it from chattering or to remove the parts, as may be desired.
20 indicates a section of a molding being cut by a cutter, as shown in the drawings. The form of outline produced will of course depend upon the cutter employed. With my improved invention in use any form of cutter may be employed, it simply being necessary to make use of correspondingly-formed sole portions.
21 indicates a member which may be provided to slide on the rods 7 and 8 and carry an auxiliary guide 22 for fixing the distance of the cutter from the edge of a board, molding, or the like.
23 is a handle which is conveniently provided on this fence portion which serves as a rest for the left hand.
The advantages of my construction will be particularly apparent to those skilled in the manufacture of woodworking-tools and in their use. It greatly reduces the number of parts necessary for a wide variety of work and the expense of the same.
What I claim is —
1. In a plane the combination of a main body member, a member laterally adjustable relatively thereto having flanges projecting downward, said flanges having horizontal openings with enlarged ends, a cutter having an irregularly-shaped edge, a sole member for each of said flanges corresponding in shape to said cutter, and screws for removably securing said sole members to said flanges.
2. In a plane the combination of a main body member, a second member slidable laterally relatively thereto, a pair of flanges projecting downwardly from said slidable member and having an opening between the same, a sole portion carried by each of said flanges, and means for adjusting said sole portions, substantially as described.
3. In a plane, the combination of a body member, a second member laterally adjustable with relation thereto and adapted with said first member to support a plane-iron, a pair of flanges carried by said second member, one in front and the other in the rear, each of said flanges having a plurality of openings elongated liorizontally, the openings in said forward flange being enlarged on their forward ends, the openings in the rear flange being enlarged on their rear ends and a pair of removable sole portions with means coacting with said flanges and the elongated openings therein for securing said sole portions to said flanges.
Signed at New Britain, Connecticut, this 25th day of March, 1904.
