R. GUASCO a ELECTRIC WRITER rued Sept. 23. 1924 Ricardo a ATTORNEY WITNESS:
Patented Oct. 20, 1925.
Breanne euasoo, or AGUASCALIENTES, MEXICO.
Applieation filed September 23, 1924. Serial No. 739,409.
To all whom it may concern:
Be it known that I, Rid-moo GUAsoo, a citizen of the Republic of Mexico, residing at Aguascalientes, in Mexico, have inventednew and useful Improvements in Electric riters, of which the following is a specification.
Persons whose duties require the frequent or continuous use of writing pens or pencils find the muscles of their hands and fingers susceptible to distortion, which results in cramps and which is commonly known as writers cramps.
An object of this invention is to produce a rest for the hand of a writer holding a pen, and in which the improvement provides two electrodes suitably wired so that a mild flow of electricity will, at desired intervals be passed through thehand of the penman to alleviate the cramped muscles and thereby overcome writers cramps.
It is a further object to produce a rest for the hand of a penman which includes a semispherical support having spaced depending legs, and adjustable elements for contacting the surface 011 which the writing is made, as well as means for supporting the thumb of the writer, the improvement also contemplating the employment of spaced electrodes wired to a battery and controlled by a switch, and whereby a mild electric current is passed through the thumb, fingers and wrist of the writer for alleviating and preventing the cramping of muscles incident to the distorting position of the writers hand in gripping the pen.
To the attainment of the foregoing and other objects which will appear as the nature of the invention is better understood. reference is to be had to the drawings which accompany and which form part of this application.
In the drawings Figure 1 is a perspective View illustrating the application of my improvement.
Figure 2 is a side elevation of the improvement As disclosed by the drawings, I make use of a semi-spherical metal member 1 that is designed to be received in the palm of the writers hand, and which has its outer rounded surface shaped to conform with the contour of the palm and fingers of the writers hand when the same is in pen gripping position. Depending from the flat base of the rest 1 there are a pair of leg members 2.
Each of these leg members has its end offset respectively. The bracket is in the nature of an arm and has a central threaded opening therethrough. Engaging thethreads of the said opening there is a screw 61 having an outer milled head 7 and its opposite end provided with a rounded headi8. Preferably the head 8 is revolubly associated with the screw.
The outer end of the bracket 4 is rounded and provided with a threaded vertical opening as well as with a transverse opening 9 which intersects the threaded opening. Screwed in the threaded opening. there is a binding post 10 "to engage onewi-re 11' of an electric circuit.
The bracket 5 is centrally formed with a ring portion 12 through which the thumb of the penman is passed. The outer face of the ring has a boss extension 13 provided with a threaded opening through which is passed a screw 14. The upper end of the screw has a milled head 15, and the lower or opposite end of the screw has a ball enlarge ment 16. The ball 16 is preferably revolubly associated with the screw.
The penman is designed to grip between the index, second finger and thumb a metal penholder 17, and to the pen holder there is attached the second wire 18 for the electric circuit. The wires 17 and 18 are connected to a battery (not shown), and the circuit therethrough is controlled by a switch (also not shown).
The improvement is especially adaptable for pupils in penmanship, and others whose duties require a continuous employment of a writing pen or pencil. The pen, with the wire 18 detached therefrom, may be used in the usual manner, but when the writers hand becomes cramped the wire 18 is attached to the pen holder which, of course, is of metal and the writer arranges his hand on the device as disclosed in Figure 1. i The current is then turned on and is caused to flow through the writers fingers, hand and wrist, the current being returned through the wire 11. The pen 17 is thus in the nature of an electrode as is the bracket 4.
When the cramp is relieved by the electric current,the hand of the operator is again detached from the improvement. The legs 2 permit of the tilting of the semi-spherical support 1, while the ball ends 8 and 16 on the screws 6 and 1 k provide supports for the device.
It is believed that the description, when taken in connection with the drawings, will fully disclose my improvement to those skilled in the art to which the same relates, but it is to be stated that I am not to be limited to such disclosure and may mak such changes therefrom as fairly fall within the scope of what I claim. It should be also stated that the electrode 17 is not to be restricted to a pen holder, as the same may be in the nature of a pen, stylus or other marking implement.
Having described claim 1. I11 a rest for the hand of a writer, electrodes, one on which the hand of the writer rests, and the other designed to be gripped between the fingers of the writer, and said electrodes designed to be hitched to a mild source of electricity.
2. In a device for the purpose set forth, a semi-spherical support tor the hand of the writer, legs depending therefrom, adjustable the inventiolr I means outward of the legs for supporting the rest, a ring element associated with the rest for the passage of the writers thumb therethrough, said mentioned device being of electric conductivity and having a conductor connected thereto, an electrode designed to be gripped between the fingers of the writer, a wire connected thereto, and a battery to which both of the mentioned wires are connected.
3. In a device for the purpose set forth,
a semi-spherical metal member providing a rest for a writers hand, oppositely disposed depending legs having oti'set ends on the flat under face of the rest, brackets extending in opposite directions from the ends of the rest, ball carrying adjustable supports on the brackets, a ring for the reception of the writers thumb on one of the brackets, an electric conductor on the other end of the bracket, an electrode designed to be gripped between the thumb and lingers of the writer,
an electric conductor removably associated therewith, and a source of current for both of said conductors.
In testimony whereof I affix my signature.
