SPECIFICATION forming part of Letters Patent N o. 642,888, dated February 6, 1900.

Application filed October 16, 1899. Serial No. 733,709. (No modali) To all 't0/"c0711, t may concern,.-

Beit known that I, ARIE VAN VLIET, a citizen of the United States, residin gin Paterson, county of Passaic, and State otNew Jersey,

have invented certain Improvements in Gombination-Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a combination-tool suitable for the use of architects, masons, dre. and so constructed as to be carried in the pocket, and thus be convenient for immediate and more or less constant use.

The invention consists in the improved combination-tool and in the combination and arrangement of its various parts,substantially as will be hereinafter pointed out and inally embodied in the clauses of the claim. n

The invention is fully illustrated in the accompanying drawings, wherein Figure l is a plan view of my invention. Fig. 2 is a view in elevation presenting one side of the tool. Fig. 3 is a view in elevation presenting another side of the tool. ,Figa et is a sectional view on the line 4 et inFig. 1, and Fig. 5 is a Sectional view on the line 5 5 in Fig. l.

The frame of the tool consists of a substantially triangular and continuous metallic strip a, having the shape of an isosceles triangle. In the two angles b c of this triangle are secured in any desired manner triangular blocks d, and connecting these triangular blocks is a pair of metallic plates e, which are formed to exactly fit in the third angle f of the triangular frame and between the sides of said angle and the hypotenuse side of said frame. The edges of the two plates c are set in recesses along the edges of the blocks d, so that their exterior faces are iiush with the exterior faces of said blocks. The plates are preferably secured to the blocks by means of screws g. It will be seen that a space or inclosure is thus formed between the two plates,

measure i, passing over a roller j, also inp closed and suitably journaled in said compartment, a plumb-bob 7c being attached to the free end of said tape-measure. In the right-angular corner of the compartment is disposed a casing Z, one wall of which consists of one side of the triangular frame and has an opening m therein, said opening being controlled by a slide n, having a thumb-piece o for manipulating it and said thumb-piece projecting through a slot 19, formed in one of the plates e. The case is adapted to receive the plumb-bob, and its opposite wall is provided with a small opening q, through which the tape-measure extends. The reel is preferably provided with the usual folding handle r, whereby it is rotated.

In the above-mentioned compartment is disposed another block s, said block being secured against the hypotenuse side of the triangular frame and between the other two blocks d. In said block is arranged a spiritlevel t, disposed .parallel to the hypotenuse side of the triangular frame, said block having a convenient opening u, exposing the spirit-level. In the triangular block d in angle b is also arranged another spirit-level z5, the same being disposed parallel to the side of the frame which is nearest the observer in Fig. 2, and also being exposed by an opening u, formed in the block. In the block d in angle c is set a third spirit-level t, arranged at right-angles to the hypotenuse side of the frame. Like the other spirit levels, this spirit-level is also exposed by an opening u, formed in the block. Y

Near the outer corner of one of the blocks d is pivoted a plate o, said plate being set in a recess w, formed in the block and having its free end beveled oit, as at x,.and adapted to engage a corresponding groove y, provided in i the end of the recess. Said plate being movable about its securing-point, therefore is adapted to be used in connection with the triangular frame to form a bevel-gage or bevel-square. One of the short sides of the triangular frame maybe projected above the faces of the plate e and one of the blocks d for a portion of its length, as at a', so as to form a flange whereby the triangular frame may be used as a try-square.

It will be observed that the triangular frame with the triangular blocks d and the plates e together form a case wherein the other parts of the device are arranged so as to be protected when not in use. Both of the faces of this case may be marked off in any desired manner to indicate lineal measurement, as indicated in Fig. 1.

The three spirit-levels are provided for individual purposes. The spirit-level adjacent the hypotenuse side of the triangular frame is useful where it is desired to determine with accuracy whether or not any two or more points are in a given horizontal plane. The spirit-level nearest the plate 2J is adapted for use when the device is used in connection with said plate, as a bevelgage or bevelsquare, and the third spirit-level is designed for use in connection with the hypotenuse side of the triangular frame, so as to ascertain whether or not two or more points are perpendicularly disposed. Of course each of these spirit-levels is useful in various other adaptations.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a combination-tool, a case comprising a triangular band constituting the frame, spaced triangular blocks secured in two of the angles of said frame, and a pair of plates spanning said blocks and forming therewith and with the frame a compartment, substan- October, 1899.
