UNITED STATES PATENT OFFICE.

PER AUGUST ANDERSON AND E IULIUS B. vPETERSON, OF CHICAGO, ILLINOIS.

COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 556,297', dated March 10, 1896. Application filed July 23, 1895. Serial No. 556,907. (No model.)

To all whom, it may concern:

Be it known that we, PER AUGUST ANDER- soN and J ULIUs B. PETERSON, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Combination-Tools, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a View of the obverse side of our improved combination-tool; Fig. 2, a view of one of the edges of the same; Fig. 3, a perspective view of the reverse side, showing the miter and square lying in their respective recesses; Fig. 4,' a detail view, partly in section, showing the manner of utilizing the miter and square; and Fig. 5, a view of the device mounted on removable feet and arranged in the form of a surveyors level.

Our invention relates to sundry improvements in combination-tools, and its object is to provide a novel, convenient, and practical device comprising a level and plummet, a miter, a square, and other useful adjuncts, all of which are arranged and united in a compact and portable form.

The peculiar advantages of the invention will be apparent by reference to the accompanying drawings, in which- A represents the body or stock of the device, which should be made of hard wood, having its ends and edges protected from wear by plates ofA suitable metal. For general purposes the tool is preferablyone foot in length andv is provided on one or both sides with a scale of inches and fractions. A circular recess 2 is formed centrally in the obverse side of the stock and contains a gravitating triplepointed index 3, which swings freely within the circle on a pivot-4 and indicates the eX- act position of the instrument on a graduated stock. When not in use the bar is retained in the groove by a screw 7 and aspiral spring 8, as shown in Fig. 4.

It will be observed that the head of the screw and the outer side of the bar are normally flush with the surfaces of the stock. Vhen it is desired to form a square the operator grasps` the stock and presses the screw inwardly with his foren ger. The bar 6 is thus forced out of its groove, and being at right angles with the stock forms a square therewith. Then the pressure is removed the spring reacts and the bar is drawn back into the groove. The miter occupies the opposite end of the stock and consists of an angle-bar 9, which engages a corresponding groove. It is adjusted and manipulated in the same manner as the square.

The device may be easily converted into a substitute for a surveyors level by mounting it upon an adjustable support formed by two pairs of folding legs l0, which are removablyattached to the ends of the stock by screws. Slotted plates 1l, provided with graduated scales, are attached to the side of the stock near its ends and form slides for adjustable sights or indexes l2,which are hinged to sliding bases 13, so that when not in use they may be folded fiat upon the surface of the stock.

If it be desired to increase the length of the device and thereby facilitate the finding of the level or inclination of an object, the buttons 14 may be turned up and temporarily fastened to a straight-edged bar by screws.`

Vhat we claim as new isl. In a combination-tool, the combination with the body or stock, having a transverse groove on one side near the end thereof, of the rectangular bar seated in said groove, the headed screw connected with said bar and the spiral spring, substantially as described.

2. In a combination-tool, the combination withthe body or stock having a groove near each end on one side, the bar and miter seated in said grooves, respectively, and flush with surface of the body or stock, the headed pin and coiled spring, substantially as described.

3. The combination with the body or stock of the tool provided with a circular recess in We have hereunto set our hands, this 5th day the obverse side containing t gravtating of July, 1895, in the presence of witnesses. triple-pointed index, of the outwardly-mov- H 1 T able bar, and the outwardly-movable mitol 5 seated in grooves in said body, the headed J l pins connected With said bar and mter and Vtnesses: the coiled springs, substantially as described. HARVEY S. AMERSON,

In testimony that We claim the foregoing ED. J. AMERSON.
