HOWARD HENRY, OF KIRKSVILLE, MISSOURI.

MEASURING INSTRUMENT.

To all whom it may concern Be it known that I, HOWARD HENRY, a citizen of the United States, residing at Kirksville, in the county of Adair and State of Missouri, have invented certain new and useful Improvements in Measuring Instruments, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in measuring instruments and more particularly to a combined miter and try square, the object of the invention.

being to provide a tool of this character for making right and left miters and which at the same time will square the work without removing the tool therefrom.

Another object of the invention is the provision of a measuring instrument of the above character which will possess advantages in points of efficiency' and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

WVith the above and other objects in view, this invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claim and shown in the accompanying drawings, in which Figure 1 is a top plan view of a measuring instrument constructed in accordance with my invention. Fig. 2 is a side elevation illustrating the device applied. Fig. 3 is an end elevation, parts being broken away.

Referring more particularly to the drawings, l and 2 indicate two parallel side members which are integrally connected at one end by means of the transverse member 3, the edges of which are tapering, as shown at 4, and terminate in an'outwardly extending end member 5 which is adapted to engage over the edge of a board or other work to which the device is to be ap lied so as to prevent lateral movement of the tool when in operation. Formed at the outer end of the member 5 is an outstanding flange 6 which rests upon a platform or other surface upon which the board or work may be rested to steady the outer end of the tool and retain the same against lateral rocking movement when the device is applied to work, the thickness of which is less than the transverse member 3. It will be Specification of Letters Patent.

Application filed August 6, 1913.

Patented June 15, 1915.

Serial No. 788,372.

noted that when the member or flange 6 is placed upon a level surface, it will prevent upon their inner longitudinal edges with,

the V-shaped recesses 8 which are arranged in alinement with the larger of the graduations 7 whereby a pencil point may be arranged within these recesses to correctly mark the work to which the instrument is applied. Thus, as illustrated in Fi 1, the two positions of the pencil point a show that any desirable angle may be readily obtained by the use of my improved instrument, the line of the angle being drawn along the intersection of the two pencil polnts.

The spaced ends of the side members 1 and 2 are connected by means of a bar 9, the ends of which are secured, as shown at 10, to the ends of the side members to prevent the outerrends of said members from spreading should they be placed under strain. From this it will be seen that in applying my improved instrument to a board or other similar piece of work, the vertically disposed end 5 is arranged over the edge of the board so that the graduations 7 will begin at the edge thereof whereby the person desiring to obtain the width of the board may readily do so. Should it be desired to cut the work at an angle, the instrument will be laid upon the work as before and a pencil or other marking device will be arranged in any manner within the recesses 8 according to the angle to be cut. The device is shifted to a diagonal angle across the work so that one of the longitudinal edges of one of the side members intersects the two pencil points so that a line may be readily drawn between the two marks, indicating the angle upon which the work is to be out.

It will be understood that the device may be used for marking blank boards longitudinally, when it is desired to rip the same by engaging the transverse member 3 with one side edge of the object and inserting a pencil point in any one of the notches 8. The side members are then moved along the board, the pencil points passing over the upper face of the board and leaving a mark,

a predetermined width from either side .of the board, whereby the object may be ripped along this line.

From the above description taken-inconnection with the accompanying drawings, it will be readily apparent that I have'pro- Vided a simple and durable measuring instrument whereby right and left miters may be quickly and readily obtained by the tapering edges 4. It will also be apparent that the device, which is preferably constructed of sheet metal, is extremely simple in construction and can be manufactured at a comparatively low cost.

While I have shown and described the preferred form of my invention, itwill be obvious that various changes inthe details of construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claim.

l/Vhat I claim is A. device of the class described including a pair of parallel side members having their outer edges provided with graduations, a transverse outstanding piece integrally connecting the side members at one end, said transverse member extending the entire width of the side members, an outstanding flange formed integral with the transverse member, and a bar having its ends secured to the opposite ends of the side members.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

HOWARD HENRY.
