WRITING AND?DRAW-ING DEVICE.
SPECIFICATION forming part of Letters Patent No. 478,129, dated July 5, 1892. Application filed February 9, 1892. Serial No. 420,900- (No model.)
To all whom it may concern.-
Be it known that 1, JOHN JAOOB PAULS, a citizen ofthe United States, residing at Lyons, in the county of Clinton and State of Iowa, have invented a new and useful WVriting and Drawing Device, of which the following is a specification.
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 persons hand to move readily and easily over the surface of paper in writing and drawing, and thereby avoid stiffnessandcrampsincidentto rapid,strained, and continuous writing.
The invention consists in the construction and novel combination and arrangementofv parts hereinafter fully described, illustrated trally-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 interposedbetween 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 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 theforgoing that asimple 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.
What I-claim is 1. Adevice of the class described, comprising a body adapted to be secured to the hand, atube depending from the body, a ball arranged within the tube and projecting from the lower end of the same, anda spiral spring arranged within the tube and interposed between 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, acentrally-depending tube having its upper end closed and provided at its lower endwith 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. In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses. 1 a
