Letters Patent No. 93,279, dated August 3, 1869.
The Schedule referred to :in these Letters Patent making part of the same.
To all whom it may concern Be it'known that we, GUs'rAv CRAMER and J ULIUs Gnoss, of St. Louis, in the county of St. Louis, and State of Missouri, have made certain new and useful Improvements in Head-Rests for Photographers and other artists; and we do hereby declare that the following is a full and clear description thereof, reference being had io the accompanying drawings, and to the letters of reference marked thereon.
The nature of this invention is in the peculiar c on-v struct-ion and adaptation of rest-prongs, in such wise that the length thereof' from their Fulcrum-pivot may he varied, and thus various positions may be achieved, in all of which the head is properly supported, whilst the parts of said. rest-device are concealed from the camera or other instrument in which the picture is being taken.
To enable those herein skilled to make and use our said invention, we will now fully describe the construction, use, and operation thereof, referring to the accompanying Figure l as a plan, and to Figure 2 as a side elevation of the said head-rest, in its usual form.
Ihc rest will be supported on a stand of the usual form, with a slido-socket und proper set-screw, for
Aholding the fulcrum-arni A, this arm being permitted to slide in or out of the socket, as may be required.
The arm A may be made of a circular or rectangular section, when it moves in the socket in accordance with the peculiar motion which it is desired to allow the arm to make.
The arm A, at its forward ends, has the blades a',
and a set-screw, b, arranged to be operated by the fingers. Between said blades a, we arrange the restprongs B. The said prongs, at their forward end, are shaped in the usual manner, to give an easy and secure support to the head of the person. At the rear end of said prongs they have the slots B', through which the set-screw l) passes.
Said slots B enable the prongs to he drawn forward, as well as turned about the pivot l), and whenever the requisite position screw b, being drawn tight, clamps the part-- securely.
In supporting the head, owing to the various styles of head-dresses, it is important to brin g one rest-prong' forward to the support of the forward part of the skull, while the other prong reoedes, and supports the rear part. Said adjustment, and similar adjustments, which, with the usualv head-rests, are difficult and often impossible, proved rest.
Having thus fully described our said invention,
What weelaim, is-
The rest-prongs B, arranged with the slots B', and combined with the fulcrum-arm A, substantially as herein set forth, to form a head-rest, the prongs whereof havea longitudinal as well as lateral movement, independent of each other.
In witness of said invention,
our hands, in the presence of- GUSTAV GRANIER.
