Description
UNITED STATES PATENT OFFICE.
GEORGE W. KING, OF PERTH AMBOY, NEW JERSEY.
ARTISTS EASEL.
Specification forming part of Letters Patent No. 40,E 7l, dated October 6, 1863.
` to the accompanying` drawing, forming a part of this specification.
This improvement does away with thev clumsy tripod now in use, the picture-frame of which has to be either raised or lowered by a peg and hole process, unnecessary to be described here, and substitutes in its place an instrument convenient in form, artistic in appearance, and desirable in ei'ect.
By means of a horizontal picture frame or stand secured to two perpendicular slides, that work in a vertical frame provided with a groove on either side, said vertical frame having a perpendicular iron rod in its center separating the said grooves, and said rod having attached to it a lever that slides up and down thereon by means of a circular` ring or cylinder at one end of the lever in conjunction with a spring fastened between this lever and said picture-stand, (to be more fully hereinafter described,) I am enabled to elevate the picture to any convenient altitude, as well as to lower it, as the case may be, and I adjust it to any fractional part of an inch, whereas in the easels now in use you are confined to certain spaces, and the picture has to be raised orlowered at least a space each time.
ln the drawings, Figurel is afront elevation of said improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical transverse section of the same. Fig. 4 is a plan or view looking down upon the same.
B B are two perpendicular bars of wood At the top they are joined by the block B, and at their lower end or base they are mortised to the portion F, which forms a part of the triangular base or stand upon which the whole rests. rIhese perpendicular bars B B are each provided with a groove, c, Fig. 2, running the whole length of the frame.
The slides D Dl work in these grooves, and are secured to the picture-stand A. Between the barsB B is the iron rod E, secured at the top to the block B, and at the base it rests on the peg c. This rod E can be taken entirely 'out by pulling the peg c, Fig. 3. Upon this rod E,below the picture stand A, is placed the lever C. The diameter of the cylindrical portion of this lever which slides on the rod E is slightly larger than that of the rod E. This lever is secured to the stand A by the staple g, and is kept hard up against the rod E by the spring h, the staple g acting as the fulcrum. N ow, by raising the leverC the picturestand A can be either raised or lowered at pleasure. The moment the lever O is free there is a friction exerted upon the rod E, which increases with the weight ofthe picture or canvas applied to the stand A, so that there is no possibility of the whole arrangement tumbling down. The stand upon which the whole thing rests is constructed of the portions G G', mitered together as shown at the apex K, and secured by the brace F, to which the superstructure is connected.
What I claim, and desire to secure by Letters Patent of the United States, is-
The application of the lever C, in combination with the grooved bars B B and slides D D', substantially as set forth.
GEORGE W. KING.
