SLOPE INDICATOR Filed Oct. 2, 1940 I M F/U/ 20 I E\% ll J es carfle I r I I k A By A iiorney Inventor Patented Nov. 18, 1941 SLOPE INDICATOR James 0. Cornell, Falmouth, Ky.

Application October 2, 1940, Serial No. 359,422

, 1 Claim.

The present invention relatesto new and useful improvements in indicators designed for use by grading contractors and others in building uniform slopes on embankments, excavations and the like and has for its primary object to provide a spirit level attachable to a string that may be extended along the slopeline during construction, at intervals, tokeep the line of slope within the desired predetermined slope limit. The spirit level has an elongated arm at one end with notches at intervals for the purpose of finding the predetermined slope or grade.

A further object is, to provide a device of this character which may be easily and quickly set up in the desired position with respect to the slope and which at the same time is simple and practical in construction, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing'forming part hereof wherein like numerals refer to like parts throughout, and in which- Figure 1 is a sectional view through a bank showing the indicator mounted in position relative thereto,

Figure 2 is a side elevational view of the indicator,

Figure 3 is an Figure 4 is a sectional view taken substantially on a line 4-4 of Figure 2.

Referring now to the drawing in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a bank which it is desired to grade and the numeral 6 designates the grade or slope indicator generally which is supported on astring 1 extending from a lower post 8 and upper post 9.

The indicator comprises a spirit level II] mounted in an elongated base II and at one end of which rises a short hanger member 12 having an upwardly inclined slotted opening [3 formed in one edge thereof for hanging on the string 1 and at the opposite end of which is a similar hanger designated at M. At the bottom end of end elevational View thereof, and

the hanger I4 is a hinge member I5 to which is hingedly attached a relatively long upstanding hanger member l6. One edge of the hanger member I6 is provided with vertically spaced upwardly inclined slotted openings l1 adjacent to each of which the slope scale designated at! is displayed.

The slotted openings I! arelikewise adapted.

to receive the string 1 at a point above the lower hanger, I2, as illustrated in Figure 1 of the drawing. In the operation of the device, presuming there is a fill to be made adjacent the bank to level the same to a predetermined slope from the shoulder to the original ground at a ratio of 2 to 1, the string is inserted in the proper slotted openings indicated on the hanger I6 and the stake 8 set in the proper position so that the spirit level will be supported in a true horizontal plane. The position of the string will thenindicate the extent of fill to be made.

A spring clip 19 secured to the fixed member l4 engages one edge of the pivoted hanger l6 tosecure the latter in an upright position.

When the indicator is not in use the hanger member l6 may be swung under the base ll of the spirit level into the dotted line position as shown in Figure 2 of the drawing, and secured by a second spring clip 26 attached to the base ll, whereby the same may be conveniently carried in the pocket of a person.

It is believed the details of construction, manner of use and advantages of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention, what I claim is-- A slope indicator comprising a spirit level, an elongated base for the level, a pair of substantially fixed hangers secured to the ends of the base in upstanding parallel relation, a pivoted hanger attached to one of said fixed hangers and rising above the latter, and adapted for swinging into a position flatwise against the base, each of said hangers having upwardly inclined notches in an edge thereof adapted to receive a supporting rope, and said notches of the pivoted hanger having indicating indicia adjacent thereto.
