. Z BY l I I adwvyfim Patented May 3, 1949 UNITED STATES PATENT OFFICE JUMP MEASURING DEVICE Doyle D. Baliif, East Gary, Ind. Application August 19, 1948, Serial No. 45,106 I 4 Claims.

My invention relates to improvements in jump measuring devices for determining the height to which persons are capable of jumping upwardly ofi a floor, or the like, in either a standing or a running jump.

The primary object of the invention is to provide a simply constructed, inexpensive device for the purpose indicated which is adapted for installation on a wall, or the like, to be swung horizontally flat against the Wall when not in use, or, swung into outstanding projecting relation to the wall for use when desired.

Another object is to provide a device of the character and for the purpose above set forth which will not get out of order or become broken as a result of rough usage to which such devices are usually subjected.

Other and subordinate objects, within the purview of my invention, together with the precise nature of my improvements will be readily understood when the succeeding description and claims are read with reference to the drawing accompanying and forming part of this specification.

In said drawing:

Figure 1 is a view in perspective of my improved jump measuring device in a preferred embodiment thereof swung into position for use;

Figure 2 is a fragmentary view in vertical section taken on line 2-2 of Figure 1 and drawn to a larger scale;

Figure 3 is a View in perspective of a modified embodiment of my improved jump measuring device swung into a position for use;

Figure 4 is a fragmentary view partly in side elevation and partly in vertical section and drawn to a larger scale to illustrate in detail the manner in which the bars of the modified embodiment are suspended.

Referring to the drawing by numerals, and first to Figures 1 and 2, according to my invention, in the preferred embodiment thereof, a series of foot and inch indicating, fiat bars are provided, the foot indicating bars being designated by the numeral I and the inch indicatin bars by the numeral 2. The bars of the series, I, 2 are graduated in length throughout the series.

Means are provided for swingably suspending said bars I, 2 by corresponding ends thereof in edge to edge spaced apart relation with lower ends stepped upwardly from the longest bar, for a purpose presently seen. The suspending means preferably takes the form of hinges 3 at upper ends of said bars I, 2 and on one and the same side of said bars, said hinges being suitably attached, as by screws 4, to a hanger arm 5, the arrangement being such that the foot and inch indicating bars I, 2 may be swung away from the hanger bar 5 in one in the same direction only, the upper ends of said bars I, 2 abutting the lower edge of the hanger bar 5 to prevent swinging of said bars I, 2 in the opposite direction from normal vertical position.

The hanger bar 5 is hinged at one end thereof, as at 6, to a bracket plate 1 adapted to be fastened to a wall 8, or other upright support, as

by screws 9 so that said arm 5 is swingable about a vertical axis, the arrangement being such that the hanger arm 5 may be swung toward the wall 8, as indicated by dotted lines in Figure 1, to position the same together with the foot and inch indicating bars I, 2 substantially fiat against the wall 8 in an out of the way position when not in use and, when it is desired to use the device, said arm 5 together with said bars I, 2 may be swung away from the wall 8 to dispose the arm in outstanding position relative to the wall 8 with the foot and inch indicating bars I, 2 disposed substantially in acommon vertical plane at a right angle to said wall.

A turnbuckle rod I0 braces the hanger arm 5 against sagging on the hinge B. For this purpose, one end of the turnbuckle rod I0 is suitably secured, as at II, to the hanger arm 5 adjacent to the free end of said arm and inclines upwardly along the hanger arm 5 to the attaching bracket 1 with its other end swivelled, as at I2 in said bracket I for swinging of the turnbuckle arm I0 with the hanger arm 5.

As will be seen, the foot indicating bars I comprise the longest end bar of the series and intermediate shorter bars of the series and these foot indicating bars are designated on one side, as at I3 to indicate in numbers of feet different heights from the floor, orthe like, not shown, in consecutively numbered ascending order beginning with the longest bar of the series.

The inch indicating bars 2 are designated on the same side thereof as the foot indicating bars I to indicate in numbers, as at I4, multiples of inches in a foot arranged in ascending order from the foot indicating bars I to supplement in inch measurements the designations I3 on the foot indicating bars.

As will be obvious, from the drawing, the foot and inch indicating bars I, 2 are swingable sidewise from normal vertical position, in the direction previously indicated, with the designations the hanger arm l8 and through which said rod 58 is extended supports said rod I'Lintermediate.
