MERRILL I /I. HUNTING,

OF CHICAGO, ILLINOIS.

EBASER SUPPORT.

Application filed May 18,

To all whom z't may concern:

Be it known that I, MERRILL M. HUNTING, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Eraser Supports, of which the following is a full, clear, and exact description.

My invention relates to improvements in eraser supporting means, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a device of the character described in which means is provided for supporting the eraser in an inoperative position in the palm of the hand, when not in use.

A further object of my invention is to provide a device of the character described in which means is provided for removing the eraser at will and replacing it with a new one when worn down.

A further object of my invention is to provide a device of the character described which is extremely compact in form, cheap to manufacture and which is thoroughly practical for the purpose intended.

Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings, forming part of this ap plication in which-- Figure 1 is a side elevation of an embodiment of my invention.

Figure 2 is a view of the mechanism illustrated in Figure 1 applied to the hand of the user, and

Figure 3 is a view of the eraser in an operative position in the hand of the user.

In carrying out my invention, I make use of a spring metal stirrup 1. The stirrup 1 is provided with inwardly extending indentations 2, adapted to engage with the eyelet portion 3 of the ordinary type of typewriter eraser common in use.

A spiral spring 41 is secured at one end to the upper portion of the stirrup 1, as shown 1922. Serial NO. 561,893.

at 5. The spring 41: is wound closely so as to form a flexible supporting member for the stirrup 1. and to engage a threaded rivet 1 on the stirrup.

A laterally bent threaded metal rod 6 is held at one end in the thread like coils of the upper end of the spring 4, as shown at 7. The opposite end 01 the rod 6 is riveted to a spring metal split ring 8 intermediate the length of its unbroken circumference.

The split ring 8 is adapted to fit the middle finger of the human hand, as shown in Figures 2 and 3, so that the eraser is supported normally in an inoperative position against the palm.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Let us assume that the person using the eraser is a typist. The ring 8 is fitted to the finger, as shown in the drawing in Figure 2 and the spring 4 acts as a means for yieldably holding the eraser up close to the palm. The hand may thereupon be used with perfect freedom as though the eraser were not in position. When it is desired to use the eraser, it is merely necessary to move the thumb so as to engage the eraser and bring the eraser to the position shown in Figure 3. Thisis made possible by the flexible spring 4-.

Obviously this device may be used to advantage by bookkeepers, artists, clerks drattsmen, and the like, since its use does not in any way prevent the ordinary handling 0t pens, pencils, or instruments of any kind. The hand is at all time free to perform whatever duty may be required, yet the eraser may instantly be called to service in the manner heretofore described.

I claim:

A device of the character described com prising a stirrup tor ren'iovably supporting an eraser, a split ring adapted to fit the finger of a human hand, and a flexible stem for movably supporting said stirrup on said ring whereby said stirrup will normally lie in close contact with the palm of said hand.
