JOINTER-GAGE- Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed December 20, 1904. Serial No. 237,630.

To all whom, it may concern:

Be it known that I, RoY (JARsoN, a citizen of the United States, residing at Pasadena, in the county of Los Angeles, State of California, have invented certain new and useful Improvements in J ointer-Gages, of which thefollowing is a specification.

The main object of this invention is to provide a device which is adapted to be readily applied to a jointer or jointing plane and to serve when so applied as a gage for guiding the plane in its longitudinal movement in such manner that the plane will cut or operate at a definite angle with respect to the side of the piece which is being planed.

Another object of the invention is to provide a device of this character which is readily removable, so as to enable it to be dispensed with when not needed and also to enable gages of different angles to be substituted at will, according to the work in hand.

Another object of the invention is to provide a device of this character which is applicable both to metal and to wooden planes.

The accompanying drawings illustrate the invention.

Figure 1 is a perspective of the gage. Fig. 2 is a side elevation of a metal plane, showing the gage thereon. Fig. 3 is a section on the X X in Fig. 2. Fig. 4 is a perspective of a wooden plane, showing the gage applied thereto. Fig. 5 is an end view of the gage having a different angle to the gage shown in Fig. 3 and showing also in dotted lines a strip or board against which the gage works.

The gage consists of a metallic plate bent to form two offset wings 1 2 with an intermediate shoulder portion 3, said wings being oppositely directed and extending from opposite edges of the said shoulder portion, the wing and oifset portions of the plate forming a substantially rigid integral body, so that said portions are held permanently at definite angular positions relatively to one another. The wing 1 is intended for attachment to a side of the plane and for this purpose may be provided with inturned ears or lugs 4 5, which are preferably resilient and bent to extend in proximity to the inner face of saidspring-clips and the shoulder portion. The shoulder portion 3 extends under the bottom of the plane, preferably slightly below the same, so as to be free of the bit. For this purpose said shoulder portion may have an upturned lip or raised portion 7 at one end to engage the bottom of the plane. The ears 4 5 spring or are bent from points at different distances from the shoulder portion, so that when the device is applied to a metal plane with the shoulder beneath the bottom of the plane and the ears 1 5 extending over the side member of flange 6 of the plane the seats or bends 8 at the base of said ears will ride onto and tightly engage the top of said sidemember, which is inclined in the wellknown manner, the said side member being gripped or wedged between the upturned lip 7 and the seats 8.

The wing 2 of the gage acts as a guidewing and extends from the shoulder 3 in a direction opposite to the member 1, either parallel to said member 1 or at an angle thereto, as may be desired.

For right-angle or square planing, which is most common, the wing 2 will be parallel to the wing 1, or substantially so, so that when the gage is adjusted on the plane, as stated, and the plane is held with the said wing 2 against the side of the board or timber 9, as shown in Fig. 3, the bottom and bit of the plane will extend at right angles to the side of the board or timber. The gage may, however, have any other angle desired. Thus for mitering it may have an angle of fortyfive degrees, as indicated in Fig. 5, where 10 indicates in dotted lines the position of the board or where the gage rests, showing how the gage in this case gives a bevel position to the plane. It is desirable to make the wing 2 with a slight outward bow or bend, as shown in Fig. 5, so that it will not be thrown out of correct angle by slight irregularities in the side of the plane.

In practice it will be desirable to provide a set or plurality of these gages with wings 2 at difierent angles, according to the usual angles required in practice.

These gages are sufliciently small and light to be carried in the pocket, and it is but the work of a moment to apply or remove the same or to substitute a gage of a ditferent angle, as may be required.

The same gage can be applied in connection with a wooden plane by providing openings 11 in the wing 2 for the reception of fastening-screws, as shown at 12 in Fig. 4, whereby the said Wing can be fastened to the side of the Wooden plane, (indicated at 13.) In this case the Wing 1 acts as a guide-Wing, said Wing 1 engaging with the side of the board being planed. The device can be made of any suitable material-for example, sheet-steel of sufficient thickness and resiliency to give the requisite stiffness to the Wings and gripping force of the spring-clips.

What I claim is 1. A gage for plane's consisting of a plate bent to form two offset Wings and an intermediate shoulder portion rigidly connecting the Wings, one of said wings having lugs extending therefrom and bent over to form spring-clips facing the shoulder portion.

2. A gage for planes consisting of a plate having an intermediate shoulder portion and 20 Wings extending rigidly and oppositely therefrom in definite angular relation, one of said wings being v provided with a plurality of spring-clips facing the shoulder portion arranged at different distances from the shoulder portion.

3. A gage for planes consisting of a plate having an intermediate shoulder portion and Wings extending rigidly and oppositely therefrom in definite angular relation, one of said wings being provided With spring-clips facing the shoulder portion and the other having fastening means for the purpose set forth.

In testimony whereof I have hereunto set my hand, at Los Angeles, California this 3d day of December, 1904.

ROY CARSON.

In presence of- ARTHUR P. KNIGHT, JULIA TOWNSEND.
