SPIEIT LEVEL.
. Application filed November 6, 1928.
My said invention relates to spirit levels and it is an object of the invention to provide an improved level of light weight, strong and durable construction all as will be hereinafter more fully described and claimed. Y
Referring to the accompanying drawings which are made a part hereof and on which similar refe i ence characters indicate similar parts,
Figure 1 is a side elevation,
Figure 2, a section on line 22 of Figure 1, and
Figure 3, a section on the line 3-3 of Figure 1. p
In the drawings reference-character 10 indicates a level body or stock of narrow vconstruction provided with oval openings having integrally formed inwardly projecting vial holding lugs. The body 10 is preferably 0 rectangular in shape formed of four flat sides having three oval openings 11 therebetween with an annular wall 12 surrounding the openings and joining the sides of the level. Such oval openings are preferably spaced one at the center of the level and one adjacent each end. The portion of the level between each end andthe adjacent oval opening'is provided with a centrally disposed inwardly extending strengthening" web or flange 13 while between the center and end oval openings a solid centrally disposed strengthening web or partition 1% is provided.
One edge of the level is preferably pro vided with a V-shaped groove 15 adapted to fit onto shafts or pipes for leveling the same, and in order to provide a. level of the requisite strength 1 provide the oval vial receiving openings with inwardlyextending opposed lugs 16. Each lug is provided with a central aperture 17 7 into which one end of a vial 18 is adapted to be inserted. This structure permits the insertion of the spirit vials without weakening the level stock by providing receiving openings in the level stock proper whereby the vials are not susceptible to injury in use. The lugs and vials in the end openings extend transversely ofthe level while those in the center opening extend longitudinally of the level, the former being adapted for determining whether an object is perpendicular and the latter .for whether an object is horizontal. By providing the center lugs as shown the length of determining Serial No. 146,775.
The vials are preferably curved as shown in order that the globuleof one of each pair of vials may be out of the way when the device is being used. I
The vials may be secured in the apertures in the lugs in any appropriate manner and the walls around the oval opening for each pair of vials is provided with a groove or channel for the reception of a cover glass 19 held in place by retaining means, as for example putty or the like. Also if desired, cushioning material QO may be placed within the apertures in the lugs to prevent injury to the vials by contact with the metal at the bottom of the apertures in the lugs.
It will-be obvious to those skilled in the art that various changes may be made in my device without departingfrom the spirit of my invention, and I, therefore, do not limit myself to what is shown in the drawings and described in the specification, but only as set stock, inwardly projecting opposed l'ongitudinally disposed vial holding lugs formed at the ends of the central oval shaped wall. a cent-rallv disposed relatively thin strengthening web between the central oval shaped wall and the oval shaped wall adjacent each end of the stock and connecting the same, and an inwardly extending strengthening web between the oval shaped walls adjacent the endsof the stock and the adjacent end of the stock defining a substantially rectangular handle opening. H
In witness whereof, I have hereunto set my hand at Port Austin, Michigan, this 3d day of November, A. D. nineteen hundred and twenty-six.
JOHN MAYES.
