ANDERS C. TERSLOSE, OF ST. PAUL, MINNESOTA, ASSIGNOR OF ONE-HALF TO JOSEPH W. SKINNER, OF LA GROSSE, WVISOONSIN.

EASEL.

SPECIFICATION forming part of Letters Patent No. 486,549, dated November 22, 1892.

Application filed February 23, 1892. Serial No. 422,695. (No model.)

T0 all whom t Wwty concern.-

Be it known that I, ANDERS C. TERsLosE, a subject ot the King of Denmark, but hav- -ing declared my intention kto become a citizen of the UnitedStates of America, and residing at St. Paul, in 'the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Easels'and Easel Attachments, of which the following is a speciiication, reference being had therein to the accompanying drawings.

My invention relates to easels; and it consists in certain novel means of connecting and adj usting the several parts and in means for supporting the canvas or p icture.

The object of my invention is to providea simple and convenient device for the use of artists in doing iield work, but which may be used for other purposes to which it may be found adapted.

In the accompanying drawings,which form a part of this specification, Figure l is a perspective view showing one of my improved easels as it will appear when ready for use. Fig. 2 is a perspective view showing the canvas support and clamp when disconnected from the tripod. Fig. 3 is a detail in crosssection of the tripod, showing the manner of attaching the brace. Fig. 4 is a detail in vertical section of the upper portion of the tripod, showing how the parts are connected. Fig. 5 is a detail with one leg of the tripod removed, showing the head-piece in cross-section and the pivoting of the central leg. Fig. 6 is a perspective view of the head-piece. Fig. 7 is a modified form of the canvas-clamp, shown in perspective; and Fig. 8 is a side view of the same.

In the drawings, a c a? indicate the legs of the tripod, and b a spring-brace by which the legs are held extended.

c indicates a spring-clasp for holdinga canvas or picture frame to prevent its displacement or to adjust it to suit the light.

d indicates a rod for attaching the clasp to the tripod by means of the hooked end CZ', the adjustable spring-clamp e, the rod g, and the wire loops f f', the legs of the tripod being secured at the top by the head-piece h.

The legs d a are provided with a series of holes, into which are titted pins t' which support a grooved board r, upon which the lower A part of the picture or canvas frame rests. It will be seen that if a picture or canvas frame is made to rest in the groove r of the board r and the upper edge be pressed between the lingers t t of the clasp c it can be easily adjusted to any position the artist may desire by drawing the rod gback and forth through loops ff', or by giving the rod g a rotary movement around the rod d it will also be observed that the groove r is adapted to prevent the base of the picture or canvas frame from slipping after being inserted therein by being formed with one sloping and one vertical side.

To adj ust the holder c to frames of variable height, the rod d is made with one of its attachingclamps adj ustably connected therewith by making it of spring-wire and bending it in such a manner as to cause it to hug the rod d closely. The clasp is shown in the drawings as being made of a single piece of wire, one end of which is formed into an eye,which the rod d passes through. The wire is then passed along the rod for two or three inches and again formed into an eye, which fits the rod closely. It is then extended at right angles from the roda distance corresponding to the thickness of the leg of the tripod to which it is to be attached, when it is again bent back nearly parallel with the rod d, the arm formed by this last bend being given a bend first in the direction of the rod d and then from it, so as to adaptit to bind the tripod when attached to it. It will be observed that by adjusting the clamp e along the rod d the whole device may be moved up or down the tripod and be made to conform to the widening or the divergent lines formed by the legs, as the case may be. pod is made rigid when set up is also formed, as shown in Fig. 3, of a single piece of springwire bent to form an eye and two outwardlyextending arms. The eye is to secure it to the leg a? of the tripod by a` staple or in any suitable manner. The arms extend outwardly, so that it is necessary to compress them before they can be inserted between the legs a a of the tripod, the legs being limited in their outward movement by the central part of the head-piece 72, as shown in Fig. 4. It will thus The spring-brace by which the tri-l IOO be seen that if the legs of the tripod be separated as far as the hinge will permit and the arms of the brace b be contracted and inserted inthe holes on the inside of the legs, as shown in Fig. 3, the tripod will be rigidly secured in its extended form, as illustrated in Fig. 1. The part h, in which the legs of the tripod are pivoted, is formed of an integrai piece consisting of the front plate h and two Vangular wings h2 h3. Between the front plate and the sides of the wings parallel thereto the legs a a of the tripod are pivoted, the leg a2 being pivoted between the wings as they extend at right angles from the main plate, the inner surface being formed smooth for this purpose and the opposite sides being beveled, as shown in Fig. 4, to accommodate the movement of the legs a a.

Figs. 4 and 5 illustrate the method of pivotin g the legs of the tripod to the head-piece 7L.

Figs. 7 and 8 show a modified form of the clasp c, that may be used instead of the one above described, which is made of spring-wire. In the last-named figures, k indicates a plate having a central slot, through which passes the shank of a thumb-screw n. The plate k has a downwardly-extending jaws, which cooperates with a movable jaw m to hold the picture or canvas frame when placed between them, the jawm being made to close upon the frame byineans of the thumb-screw, said jaw being provided with an inwardly-extending lug m', which iits the slot in plate 7c, the lug being perforated and provided with a thread, which takes the shank of the thumb-screw n, by means of which the jaw can be made to traverse the plate 7c in the direction of the slot.

p p are two oppositely-disposed posts attached to or formed integral with the plate 7c, having their upper ends perforated to receive the rod g, as in the case of the wire clasp.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An easel consisting of the legs a a a2, head-piece h, and brace b, the legs a a being provided with holes and iitted with pins t' i, iu combination with a board r, provided with a groove 1", one side of which is inclined and the other vertical, substantially as described.

2. In an easel, a tripod consisting ot' the parts a a a2, connecting head piece h, and spring-brace b, substantially as described.

The combination of the tripod and rod d, adjustably connected thereto, with the clasp c and rod g, the rod g being adjustably connected to the rod d and to the clasp, substantially as described.

4.-. The combination of the rod d with the adjustable attaching device e, consisting of a wire bent so as to form two eyes and aspring by which it is secured to said rod, substantially as described.

5. The combination of the rod d with the clamping device e, provided with the arm e', the device being adj ustably connected to the rod, adapting it to adjustment upon the easel, substantially as described.

In testimony whereofI afiix my signature in presence of two witnesses.
