To all whom it may concern:

Be it known that I, WILLIAM CLARK, a citizen of the United States, and a resident of the city of New York, Long Island City, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Plane, of which the following is a full, clear, and exact description.

This invention relates to wood working implements and particularly to a plane capable of a plurality of adjustments to accomplish different purposes, and has for an object the provision of such a structure as to be quickly and easily adjusted to respond to the different requirements.

Another object of the invention is to provide a plane in which the main cutting blade is held in runways while other implements may be clamped on different sides provided therefor so as to coact with the central blade, or act independently thereof.

A further object of the invention is the provision of a plane having a central guide for a central blade, a pair of side guides for cutting tools of different kinds, a front guide and offset portions on the sides for allowing the side implements to act as beading tools, grooving tools, and the like.

A still further object, more specifically is the provision of a single skeleton or frame and a plurality of tools and clamps associated therewith whereby a single frame can be used with the different tools necessary for substantially all requirements of a carpenter.

In the accompanying drawing:

Figure 1 is a top plan view of a plane disclosing an embodiment of the invention.

Fig. 2 is a side view of the plane shown in Fig. 1.

Fig, 3 is a bottom plan view of the plane shown in Fig. 1.

Fig. 4 is a longitudinal vertical section through the plane shown in Fig. 1, same being taken on line 4–4.

Fig. 5 is a transverse sectional view through Fig. 1 on line 5–5.

Fig. 6 is a fragmentary detail sectional view through Fig. 4 on line 6–6.

Referring to the accompanying drawing by numerals, 1 indicates a frame or skeleton of a plane, which plane is provided with a smooth bottom 2 and offset portions 3 and 4, said offset portions being utilized when one of the side tools is being used as a beading tool, or when a piece of material is being specially formed. The body 1 is provided with a pair of grooves 5 and 6 in which the blade 7 is slidingly positioned, said blade being clamped in any desired adjusted position by a thumb screw 8 which extends through a transverse bar 9 connected at the ends to the body 1 or formed integral therewith. The blade 7 extends for almost the full width of the bottom 2 and projects through a comparatively large opening 10, and the grooves 5 and 6 causing the blade to extend through the opening in such a manner, as there will be provided a passageway 11 in front of the cutting edge 12 of the blade and a passageway 13 at the rear of the blade. The side walls of frame 1 are cut away at 14 which is opposite the cutting edge 12 whereby chips, shavings and the like cannot become wedged beneath the blade or between the blade and the side walls. As the blade 7 moves upwardly and downwardly in the guiding grooves 5 and 6 the cutting edge is always true in respect to the bottom 2 so that a proper shaving will be produced when this blade is in use.

At the front part of the frame 1 a transverse plate or section 15 is provided which may be independent of the frame or formed integral therewith, said section having a slot 16 extending transversely of the body 1 as shown more particularly in Fig. 1. A thumb screw 17 extends through this slot and also through the slot 18 in the tool 19, slot 18 extending at right angles to slot 16. A nut 20 is normally positioned on the end of screw 17 so that when the tool 19 has been properly adjusted vertically and also horizontally thumb screw 17 may be tightened and tool 19 clamped in place. The nut 20 may be of the ordinary type, but is preferably provided with overhangin shoulders 21 projecting on each side of the tool 20. The tool 19 may be used for providing a central bead, rabbit, or any other desired structure and preferably extends through an aperture in the bottom 2 centrally thereof as shown in Fig. 4 so that there will be a passageway both in front and back of the tool as well as on both sides, as the aperture 22 usually extends for the full width of the section 15 though the tool may be positioned so as to operate substantially at any point in front of the blade 7. On one side of the frame 1 is positioned the offset 3 which merges into an opening 23 whereby there is provided a shoulder 24 for receiving a tool 25. Tool 25 may be an ordinary blade with a straight edge or may be a beading tool, or a tool of any preferred kind. Regardless of the form of the cutting edge 26 on tool 25 said tool is held in place by a thumb screw 27 threaded into the side wall 28 of frame 1, said thumb screw having a thumb engaging member and a flange 29 overlapping the tool 25, but preferably not overlapping shoulder 24 whereby the tool is pressed tightly against the wall 28 and held in position while in operation. Wall 28 is provided with a boss 30 spaced a short distance above the shoulder 24, said shoulder being spaced a sufficient distance for allowing the tool 25 to freely slide, but will prevent any twisting motion thereof.

On the opposite side of the frame 1 and associated with the wall 31 and the offset 4 is a tool 32 and associate parts of identical construction with tool 25 and associate parts so that no additional description will be necessary.

What I claim is:

1. A plane comprising a frame having a pair of upstanding side members, said side members having facing guideways for receiving a planing tool, means for holding said planing tool in said guideways, each of said side members being provided with a shoulder for receiving auxiliary tools, and a threaded lug, a clamping screw threaded into each of said threaded lugs, each of said clamping screws having an enlargement overlapping the tools supported by said shoulders for clamping the tools in place.

2. A plane comprising a frame having a smooth bottom and a pair of upstanding sides, said sides having facing inclined grooves for receiving a planing tool, said bottom having a notch at the base of said grooves merging into said grooves, and means for locking a planing tool in said inclined grooves.

3. A plane comprising a frame formed with a smooth bottom and a pair of upstanding sides, the juncture of said sides and said bottom being formed with offsets or shouldered portions, the outer surface of said shouldered portions being parallel with said bottom, means for clamping a cutting tool so as to extend through said bottom and operate as an ordinary plane, and means for clamping a tool against each of said sides so as to project through the outer surface of said shouldered portions.

4. A plane comprising a frame having an opening in the bottom, means for holding a planing tool so as to extend through said opening, an upstanding transversely slotted member connected with said frame in front of said opening, and means adjustable along said slot and extending therethrough for clamping a tool against said upstanding member.

5. A plane comprising a frame having a centrally arranged seat for a comparatively large planing tool, side seats adjacent said central seat for side planing tools, a front tool seat arranged centrally, and independent means adjacent each of said seats for clamping tools on the respective seats.

WILLIAM CLARK.

To all whom it may concern:

Be it known that I, JOSEPH O. LANGFORD, a citizen of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Plane Attachments, of which the following is a specification.

This invention relates to planing tools and more particularly to an attachment therefor, in the nature of a guard or fender.

The principal object of the invention is to produce a guard for a plane-stock, whereby the hand of the operator is protected from injury by splinters, etc., during the use of the planing tool.

A further object of the invention is to produce a guard of this character which will prevent splinters and the like from striking the front ends of the side plates, and which may be readily attached to or detached therefrom whenever desired and with no difficulty whatsoever.

With these and other objects in view, my invention consists in the details of construction, arrangement and combination of parts, as will be hereinafter more fully described in the following specification and pointed out in the accompanying drawings, wherein:

Figure 1 is a top plan view of a plane, with my attachment thereon, Fig. 2 is a longitudinal sectional view of the attachment and the end of the plane to which it is secured, Fig. 3 is a side view of the attachment shown detached from the plane, and Fig. 4 is a detail bottom plan view of the same.

Referring now more particularly to the several views of the drawings, it will be noted that my attachment is shown, in several instances, applied to a planing tool known in the art as a block or jack plane, although it is to be understood that the invention can be used equally well with any other type of plane.

In this particular instance, 1 indicates the flat lower surface of the plane stock provided with a cross brace 2 at one end and a handle 3 at the opposite end. This surface is further provided with a transversely extending slot 4 arranged in proximiity to the cross brace 2 and for the purpose of permitting the plane bit or cutting blade of the plane to extend therethrough for engagement with the surface to be planed. A suitable inclined support or rest 5 is arranged adjacent the slot 4 and is of the type usually employed for supporting the plane bit in its various adjustments through the slot 4.

Formed at the forward end of the plane stock and midway between the side walls 6 and 7 thereof, is a raised boss 8 having a threaded bore therein adapted to receive the threaded shank 9 of a knob 10. This knob constitutes a gripping means for the operator to permit him to control the movement of the plane while being used. When using the plane, the operator of course, propels it over the surface of the board, etc., by means of the handle 3, but it is well-known in the art that serious injuries have been occasioned by reason of the fact that large splinters have been forced into the hand which grasps the knob piece 10 during the movement of the plane, besides interfering with the proper manipulation of the planing tool. It is the object of my invention to overcome this objectionable feature and to provide a guard for the operator’s hand, so that the splinters will be deflected from engagement therewith.

In carrying out my invention I provide a shielding plate or guard 11 having an enlarged end 12 and a restricted end 13, the latter being provided with an opening 14 adapted to receive the raised portion 8 of the plane stock after the knob 10 has been unscrewed therefrom and the guard member attached to the plane in the manner illustrated to advantage in Fig. 2 of the drawings. The upper surface of the guard is inclined and projects forwardly beyond the rounded front edge 16 to provide an overhanging flange 17. The marginal edge of the restricted portion 13 is beveled as indicated at 18, said edge terminating abruptly on both side of the plate to provide parallel straight edges 19 for closely engaging the inner faces of the sides 6 and 7 respectively of the plane stock. Shoulders 20 are formed forward of the edges 19 for engagement with the front ends of the side walls 6 and 7 and are undercut as seen in Fig. 3 so as to conform to the curvature of said ends, thus permitting the guard member to be firmly seated in place when attached to the plane. The knob 10 when its shank 9 is screwed into the raised boss 8 will abut against the upper surface of the guard 11 and will securely retain the latter in position.

When using a planing tool with my attachment thereon, it is evident that any splinters which might normally tend to wound the hand of the operator grasping the knob 10, will be deflected therefrom by reason of the forwardly extending and overhanging guard. It will be seen that such splinters must necessarily engage the front edge 16 of the attachment and be turned aside by reason of the overhanging flange 17, consequently prevented from striking the front ends of the side walls or projecting in the direction of the knob, about which the hand is gripped. This attachment may be constructed of any suitable material adequate for the purpose in view, and may of course be so constructed as to be readily attachable to any type of plane in use. It is of most simple construction and can be applied to or removed from the plane without the necessity of changing the plane in any material particular.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is :–

The herein described attachment for a plane whose stock comprises a flat bottom plate and upstanding side walls, the same consisting of a boss rising from said bottom plate and having a threaded cavity, and a knob having a threaded shank for engaging said cavity; combined with a guard plate having a restricted rear end with an opening passing over said boss, straight parallel side edges engaging the inner faces of said side walls, undercut shoulders forward of said edges resting upon the upper edges of the walls at the front ends of the latter, a transversely rounded front end flush with the front end of the bottom plate, and above it an overhanging flange, the whole for use substantially as described.

ln testimony whereof I affix my signature in presence of two witnesses.

JOSEPH O. LANGFORD.
