LEVEL.

AppIication filed February 17, 191.5.

To all 10 ham it may concern Be it known that I, FRANK B. MILLER, a citizen of. the United States, and a resident of Unionville, in the county of" Hartford and State of Connecticut, have invented a new and Improved Level. of which the following is a specification.

My invention relates to the class of implements that are commonly used for the purpose of determining horizontal planes or levels, and an object of my invention, among others, is to provide a device of this class that shall be durable and eliicient in oper ation, neat and attractive appearance and inexpensive in construction.

One form of device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is aperspective view of a leve Fig. 2 is adetail view in cross section through the same on plane denoted by dotted line 2-2 of Fig. 1. Fig. 3' is a perspectiveview of a level embodying my invention and of slightly different construction from that shown in Fig. 1. Fig. 4 is a view in cross section on plane denoted by dotted line 44 of Fig. 3. Fig. 5 is a perspective view of a level of still another slightly different form.

It is the purpose of the present invention to produce a level from thin sheet metal, and one that while light and attractive in appearance shall at the same time possess sufficient strength and rigidity to render it eiiicient and accurate in use.

My invention also contemplates the formation of the entire device with the exception of the bubble glass of a single piece of sheet metal.

In the devices shown in the accompanying drawings each structure comprises a stock or beam having a flange or rest at the bottom edge and a socket for a bubble glass at the upper edge. These parts are all formed of a single piece of metal stamped to proper form and then bent to shape suitable for a level.

In the form of device shown in Fig. 1 the flange or rest 7 is formed by bending the metal backward upon itself from opposite edges and then upturning the metal at the center of the flange and at right angles Specification of Letters Patent.

thereto to form the stock or beam 6, said upturned parts resting snugly one against the other. When the blank is stamped out a projection is formed near the lengthwise center at one edge and in forming the level this projection, extending from the upturned side 8, is bent to form a socket 9 for the bubble glass 10. the latter being secured within this socket in any suitable manner. The formation of the base by bending the metal backward upon itself from opposite edges provides the bottom for the rest. without seam or projection and upon which the instrument is supported, so that there is little liability of the implement becoming uneven or bent out of shape. In bending the projection to form the sock t the edge 11 of this projection is set down close against the upper edge of the side 19 of the stock or beam, thus securing the sides firmly in contact onewith the other and providing a structure that is extremely rigid. and particularly free from liability to distortion.

In the form of device shown in Fig. 3 the stock or beam 13 is formed of a single piece of metal and the socket 1 is made in the same manner as that herein above set out with respect to Fig 1. In the form of the device shown in this figure the flanges constituting the rest are composed of tabs 15 which are formed on the bottom edge of the stock or beam and are bent out alternately in opposite directions.

In the structure shown in Fig. 5 the flanges constituting the rest 16 are bent outwardly in opposite directions from the stock or beam 17, the latter being composed of two side parts resting one against the other. as in the device shown in Fig. 1, and the socket 18 for the bubble glass is formed from a narrow piece connecting the two side parts 17 when the blank that this form of the device is made from, is stamped out, this narrow piece being bent into socket form, as will be readily understood by an examination of Fig. 5 of the drawings.

In all of the structures herein shown and described a proper opening is made in the socket through which the bubble may be observed for the purpose of operating the implement.

While I have shown and described herein satisfactory constructions of implements embodying my ideas, these may be departed I extending in opposite directions to form a rest, the sheet metal having the portion near its upper edge bent into socket form to receive a bubble glass, such edge resting against the upper edge of the stock proper.

3. A level body formed from a single piece of sheet metal and comprising a stock having at its lower edge flanges extending in opposite directions from the stock to form a rest, the bottom of which is smooth and Without seam, and the sheet metal near the upper edge of the stock being bent into socket form to receive a bubble glass.

4. A level body formed from a single piece of sheet metal comprising a stock,'a rest comprising two thicknesses of sheet metal, one thickness consisting of such metal bent in opposite directions from the lower edge of the stock, and a socket formed by bending the metal above the upper edge of I the stock into tubular form to receive a bubble glass. v

5. A level body formed from a single piece of sheet metal comprising a stock of two thicknesses of such sheet metal extending in opposite directions near their lower edges to form a rest, and a part of which rest is bent to comprise two thicknesses of metal, and the portion of the metal near the upper edge of the stock being bent into socket form to receive a bubble glass. 7

6. A level body formed from a single piece of sheet metal comprising a. stock of two thicknesses of such sheet metal extending in opposite directions near their lower edges'to form a rest, and a part of which is bent to comprise two thicknesses of metal, and a portion of one thickness of the metal near theupper edge of the stock being bent into socket form to receive a bubble glass,

the free edge of such sheet metal comprising said socket resting against the upper edge of the other thickness of the metal comprising the stock. r

7 A level body formed from a single piece of sheet metal and comprising a stock of tWo thicknesses of such metal resting firmly against one another, a rest comprising flanges extending in opposite directions from the lower edge of'the stock, and a,

socket piece formed from a projection of one thickness of the stock, such projection being bent intotubular form with its edge resting against the upper edge of the other side piece of the stock.
