'CHARLES L.`ALExANnER.
Compositors Arm-Rest.
N0.127,208. Patented May 28,1872.
' InVe-ri UNITED 'STATES CHARLES L. ALEXANDER, OF WASHINGTON, DISTRICT OF COLUMBIA.
IMPROVEMENT IN COMPOSITORS ARM-RESTS.
Specification forming part of Letters Patent No. 127,208, dated May 28, 1872.
Specication describing certain Improvements in Compositors Arm-Supports, invented by CHARLES L. ALEXANDER, of the city of Vashington, iu the District of Columbia.
In the drawing forming part of this specification, a is an arm-rest; b, a horizontal support; c, an elastic or nonelastic cord; d, a coiled spring or elastic cord; e, a non-elastic cord or Wire, to modify the extensibility of the part 5 f, a Work-stand; g g, uprights from the ii'oor orstand; h, a set-screw.
This invention is intended to aid compositors in their labors, both in setting and distributing types; and is especially advantageous where small types are set in narrow measures.
This rest, marked a in the drawing, is to be fashioned after the shape of the arm, and should be soft and yielding on the'inside, and reticulated for the passage of air through it. It ml y be made of Wood, of metal, of vulcanized rubber, of leather, or of any desired material, and may open and close Wholly or partially by a spring or catch. It should be suspended from the ceiling or from a horizontal bar proceeding from the Wall, orfroma crosshead, b, supported by an upright or uprights secured to the stand or to the floor. A cord or strap of leather, or stra-p of rubber, as shown at c, will serve to sustain it; but as extensibility under light strain is important, When the cord7 rope, or strap is not Y elastic it is essential that one or more springs shall be used at the end of orintermediately in the cord or its equivalent, as shown at d. A long cord is requisite, that the hand may not vary appreciably from its vertical relation to the point of suspension. But'as the degree of extensibility must be variable, according to the choice of each compositor, and according to the varying Weight of the stick or handful of matter, adj ustingarrangementsbecomenecessary; and hence the stiffeners e are provided; but it is obvious that other means of equivalent effect may be used.
The object of this device may be attained by a string, pulley, and counterpoise, but in a less efcient manner. Other discretionary means may also be employed. l
This invention Will doubtless be found useful in assisting the left hand in several arts, as in sewing, in Watch-makin g, and in artistic painting; and in assisting the right lia-nd, as in writin g, and in cutting With scissors o1' shears.
I am awa-re that weighty tools and parts of machines have often been suspended; but I do not contemplate such purpose, my invention relating entirely to the relief of the arm in its labors, and the improvement of its capabilities for better and more facile manipulations.
I hence claim- Sustaining the hand, wrist, or arm in its labors, by a yielding suspended support, sub stantially as described.
CHAS. L. ALEXANDER.
