COMBINATION-TOOL FOR' SQUARING, LEVELING, 80G.

SPECIFICATION forming part of Letters Patent No. 359,372, dated March 15, 1887.

Application filed February 18, 1886. Serial No.192,349. (No model.)

'To all whom it may concern.-

Be it known that I, DAVID WEsLEY WAR- NOOK, of Lexington, in the county of Fayette and State of Kentucky, have invented a new ings, forming a part thereof, in which Figure l is a side elevation. Fig. 2 is aside elevation with the side of the body of the tool removed. Fig. 3 is a detail view showing the compasses in position for use. Fig. 4 is a transverse section taken on line or w in Fig. 1. Fig. 5 is a section taken on line y y in Fig. 4.

Similar letters of reference indicate corresponding parts in the different figures of the drawings. a

The object of my invention is to provide a combination-tool for squaring,leveling,plumbing, centering cylinders, laying off angles, starting a saw-kerf for cutting a key-hole, and for cutting lace-leathers for belting.

My invention consists in various instrumentalities by which these objects are attained, as hereinafter more fully described.

The body A of the combinationtool is provided with a longitudinal groove,a,in one edge thereof, and to one end of the body and in the longitudinal groove is secured the square blade B, which is cut away at an angle of forty-five degrees upon its inner edge near the body A, forming a beveled shoulder, a, for receiving and supporting the end of a slotted bar, 0, when in the position shown in dotted lines, Fig. 1. The bar 0 is fitted to the slot of the body and is provided with a pivotal pin, b, which projects through a slot, 0, formed in the side of the body, and retains the bar Gin the body A, while admitting of adjusting it in position for use, or folding it into the body A when not in use. The end of the slot 0 nearest the blade B is curved toward the blade, and the opposite end of the slot is provided with a branch, d. p

In the groove a of the body of the instrument is placed a thin pair of compasses, D, with a pivotal pin, 6, projecting through the slot 0 in the side of the body A. When it is desired to use the bar 0, the compassesD are drawn forward in the slot into the branch d and the pivotal pin of the bar 0 is moved forward to the extremity of the slot 0, beyond the branch d, when the pivot of the compasses may be moved back intothe slot 0 and the compasses may-be pushed back entirely within the body A.

When the bar 0 is folded over upon the shoulder a, as shown in dotted lines 1, Fig. 1, a left miter can be obtained; and when the bar has been pushed back in the slot 0 to the angle of the body and blade and then inclined outward at an angle of forty-fivedegrees, as shown in dotted lines 2, said figure, a right miter can be obtained. By this construction both right and left miters can be obtained without reversing or turning the square over.

In the body Ais formed a cavity,into which the protractor E may be turned when not in use. The outer edge of the body A is provided with a slot, 0, for receiving a key-hole saw, F, which is provided with a slot, in the wider end to receive a pin, h, passing through the body A, and at one end of the slot 9 is formed a notch, i, in which the pin h is received when the saw-blade is opened.

To facilitate the opening of the saw-blade, the back thereof is provided with a nick, j, for receiving the thumb-nail for lifting it out of'the handle of the body A. In one side of the body, near the middle thereof, is secured a spirit-level bulb, G, and to the end of the body A, at oneside of the blade B, is secured a spirit-level bulb, H. The bulbs G H are employed for leveling and plumbing in the usual way.

' The body A of the square also forms the body of the plumb and level.

In a transverse groove, is, formed in one side of the body A, is placed a steel bar, Z, which is bent at right angles at its extremity toward the blade B, and is formed into a knife, m, having a shank, a, which projects through a slot, 0, in the blade 13, and is provided with a nut, 10, for clamping the barl and knife min any desired position along the length of the slot 0.

The knife m is designed for cutting lacestrings for belting, and is made adjustable to admit of cutting laces of different widths. When the knife m is not in use, it is moved forward into a notch, q, in the edge of the body A.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp 1. lhe combination of the body A,having slots a a, the blade B, provided with the beveled shoulder a, and the slotted bar 0, provided with the pivot'b, substantially as herein shown and described.

2. A. combination-tool consisting of the bod y A, having slots at c, the blade B, having the beveled shoulder a, the slotted bar (1, providedwith the pivotal pin 1), the compasses 1), provided with the pivotal pin e, the protractor E, the spirit-level bulbs H G, and the bar Z, carrying the lace-cutting knife m, sub stantially as herein shown and described.
