COMPLETE SPECIFICATION.
Improvements in Writing and Drawing Devices.
I, JOHN JACOB PAULS, of Lyons, in the County of Clinton, and State of Iowa,
United States of America, Gentleman, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The invention relates to improvements in devices for assisting in writing and
drawing.
The object of the present invention is to provide a simple and inexpensive device
adapted to be readily applied to the hand to assist a person in writing and drawing
and capable of enabling a person's hand to move readily and easily over the surface
of paper in writing and drawing, and thereby avoid stiffness and cramps incident to
rapid, strained, and continuous writing.
The invention consists in the construction and novel combination and arrangement
of parts hereinafter fully described, illustrated in the accompanying drawings and
pointed out in the claims hereto appended.
In the drawings,
Figure 1 is a perspective view of a device constructed in accordance with this
invention and applied to a hand.
Figure 2 is a similar view of the device detached.
Figure 3 is a vertical sectional view.
Like numerals of reference indicate like parts in all the figures of the
drawings.
1 designates a curved body having a concaved upper face and provided with
a centrally-arranged sleeve 2, depending from the lower face of the body and
adapted to contain balls 3, one of which protrudes slightly and is adapted to
rest upon the supporting surface to enable the hand in writing and drawing to
move freely and steadily. The third and fourth fingers are placed in the concaved
upper face of the body, which is retained to the hand by an elastic band 4 secured
to the body. The sleeve 2 has its upper end closed and is provided at its lower
end with an inwardly-extending flange 5, which prevents the displacement of the
balls.
A spiral spring 6 is interposed between the inner ball and the upper end of
the tube to form a yielding elastic cushion whereby the device will readily give
to the pressure of the hand and will not seem hard and stiff. By this arrangement,
the lower ball, which rolls on the supporting surface, has very little friction and the
device is adapted to move freely.
By using the lower ball as a center or pivot a perfect curve may be drawn, and
by rotating the paper beneath the pencil and holding the latter rigid circles may
be accurately drawn with a little practice.
It will be seen from the foregoing that a simple and inexpensive device is provided,
that the same may be readily attached to the hand and will greatly facilitate free
and easy movement in writing and drawing and that all cramps and stiffness incident
to continuous and strained writing will be avoided.
The device may be advantageously employed for erasing pencil-marks by placing
an ordinary pencil rubber eraser on the tube.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A device of the class described, comprising a body adapted to be secured to
1

the body and the ball and forming an elastic cushion, substantially as described.
2. A device of the class described, comprising a curved body having a concaved
upper face, a centrally-depending tube having its upper end closed and provided
at its lower end with a flange, balls arranged in the tube, one of the balls protruding
through the lower end of the tube, a spring interposed between the balls and the
upper end of the tube, and an elastic band extending across the upper face of the
body, substantially as described.
Dated this 28th day of September 1892.
