Specification of Letters Patent.
Patented J an. It, 1911?.
Application filed March 10, 1916. Serial No. 83,431.
To all whom it may concern Be it known that I, WILLIAM A. Ronsnn, a citizen of the United States, residing at McKee City, in the county of Atlantic and State of New Jersey, have invented new and useful Improvements in Levels, of which the following is a specification.
The invention relates to levels, and more particularly to the class of spirit levels.
The primary object of the invention is'the provision of a level of this character wherein the spirit tubes or cylinders are mounted-in the plumb beam in a novel manner so that the same can be firmly secured in place, and in event of either or both of said tubes or cylinders becoming broken the same can be readily removed for the substitution of new tubes or cylinders with despatch.
Another object of the invention is the provision of a plumb level of this character wherein the spirit tubes or cylinders are formed with terminal ears which are clamped between metal strips, the latter being seated and fastened in countersunk portions within the plumb beam to be flush with one face thereof and the spirit tubes or cylinders confined within a hole provided therefor in said beam so that they can be readily inspected for determining accuracy in the work.
A further object of the invention is the provision of a plumb level of this character which is simple in construction, thoroughly reliable and efficient in its purpose, strong, durable and inexpensive in manufacture.
Uther objects will be in part obvious and in part hereinafter set forth.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and the application of which will be defined in the appended claims.
In the accompanying drawings: Figure 1 is a side elevation of a plumb spirit level constructed in accordance with the invention; Fig. 2 is a sectional view on the line 2-2 of Fig. 1; Fig. 3 is a fragmentary vertical longitudinal sectional elevation; and Fig. 4 is a perspective view of one of the spirit tubes or cylinders removed.
Similar reference characters indicate corresponding parts throughout the several views of the drawings.
Referring to the drawings in detail, A designates generally a plumb beam. In
this instance, the same. is made from wood, although it can be made from any other suitable material, and is formed with an elongated opening B for accommodating the spirit levels hereinafter fully described. In opposite faces of the plumb beam A, at the longer edges of the opening 13, are countersunk portions 5, and these portions on one side of the said beam accommodate inner and outer clamping plates or strips 6 and 7 respectively, while in the countersunk portions at the opposite side of the plumb beam are facing strips 8, the outer clamping strips 7 being also designed to serve as facing strips and between the inner and outer clamping strips 6 and 7 are fastened the spirit levels hereinafter fully described. 1
The spirit levels each comprise a metallic tube 9 or cylinder having a peep-opening 10 therein, and at opposite ends of this tube or cylinder are perforated ears 11 which lie between the inner and outer clamping plates 6 and 7 and have passed therethrough fasteners 12 which also secure the said clamping plates to the plumb beam A, while within the tube or cylinder 9 is a glass spirit tube 13 containing fluid constituting the level, which tube is of the ordinary well known construction. The spirit levels are arranged in spaced parallel relation to each other within the opening B to extend transversely thereof and operate in the usual manner for enabling the user of the plumb beam A to determine with accuracy the level of the work or the plumb thereof.
From the foregoing description, taken in connection with the accompanying drawing, the construction and manner of use of my improved spirit level will be readily understood and, therefore, a more extended explanation has been omitted.
Having described my invention, I claim:
1. The combination with a plumb beam having an elongated opening therein and also having countersunk portions at the longer edges of the opening, inner and outer clamping strips secured in the countersunk portions at one side of the plumb beam, and spirit levels having ear extremities engaged between the inner and outer clamping strips.
2. The combination with a plumb beam having an elongated opening therein and also having countersunk portions at the longer edges of the opening, inner and outer clamping strips secured in the countersunk portions at one side of the plumb beam, In testimony whereof I aflix my signature spirit levels having ear extremities engaged in presence of two witnesses.
