2 Claims.

This invention relates to an attachment for spirit levels and has for its primary object the provision of a magnetic holder which will maintain the spirit level in a fixed position against the face of an upright metallic member.

Another object of the invention is to provide a magnetic level attachment which holds the level against the steel upright without the necessity of supporting such a level by hand.

Yet another object of this invention is to provide a magnetic level attachment which is automatically held against the fac of an upright while the latter is being adjusted to its correct vertical position with respect to the ground surface. Such adjustments may be made by merely referring to the bubble in the spirit level automatically maintained against the upright. As a consequence, a great deal of time a and labor is saved in adjusting the upright to its proper vertical position.

These, together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the device, a preferred em bodiment of which has been illustrated by way of example only in the accompanying drawings,

wherein:

Figure l is a perspective view of the attachment as applied to a vertical steel beam;

Figure 2 is a side elevational-view of one of the complementary members making up th attachment of the instant. invention;

Figure 3 is a top plan view of the device; and

Figure 4 is an end elevaticnal view of one of the devices shown in Figures 2 and 3.

Specific reference is now made to the drawings. In the several views in the accompanying drawings and in the following specification reference characters indicate corresponding elements throughout.

Indicated generally at It is a conventional I steel I-beam which is to be erected and adjusted in a vertical position in any suitable structure.

'To facilitat erection of this I-beam in its proper extend beyond the magnets it themselves to provide bearing surfaces l8 for the I-beam Iii.

The plates it are secured to the magnets I4 by bolts 20 which extend through suitable aligned apertures in the plates and a bore 22 in the magnet. It will of course be understood that the plates It may be removably secured to the magnets !4 by providing external screw threads at the end of the bolt and an internally screw threaded nut 24 to engage such threads.

The opposing plates I6 are further provided with means for detachably securing and retaining thereon a conventional spirit level 20 which, as shown in Figure 1, includes a pair of vertical indicators 28 and a horizontal indicator 30. The level retaining means consists of conventional spring clips 32, and as shown clearly in Figure 4, a pair of such clips is removably secured by means of screws 34 to the longitudinal edges of each of the opposing plates Hi. The spirit level 26 is simply resiliently and frictionally retained in these spring clips.

In practical operation, the spirit level 26 is assembled upon the spaced magnets l4 and simply positioned upon a face 36 of th I-beam ID. The I-beam. is then adjusted to its correct inclination to the ground surface when the spirit level indicators 28 and 30 properly register this inclination.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown, and described a preferred embodiment of the invention th same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appendedclaims.

Having described the invention, what is claimed as new is:

1. Means for suspending a level on a metallic upright comprising a pair of spaced substantially rectangular magnets, a pair of opposingmetallic plates removably secured to opposite faces of and extending beyond said magnets, and means carried by the opposing plates for detachably retaining a level thereon, said level retaining meansincluding a pair of spring clips removably secured to each opposing plate,'the ends of the plates adapted to engage the metallic upright being in the same plane with the straight edge surface of a level.

2. Means for suspending a. level on a metallic upright comprising a pair of spaced substantially rectangular magnets, a pair of metallic plates removably secured to the opposite faces of each of said magnets and extending beyond each of said magnets, and means carried by the adjacent plates of the spaced magnets for detachably retaining a level thereon, said level retaining means including a spring clip removably secured to each cf said adjacent plates, the ends of all of, the plates adapted t0 engage the metallic upright being in the same plane with the straight edgesurface of a level.
