Letters Patent No. 101,37 7, dated March 29, 1870.

IMPROVEMENT IN EASELS.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom it may .concer/11 Be it known that we, GEORGE MUs-'GER and J AMES W. SCHERMERHORN, of New York, in the State of New York, have invented a new and useful Improvement in Easels, Blackboards, 8m.; and we do hereby declare that the following is a full, clear, and description of the same, reference being had to the accompanying drawings and letters yof reference marked thereon, making a part of this specification, in which- Figure 1 is a front elevation of the easel.

Figure 2 is a side elevation of the same.

To enable those skilled in the art to make and use this invention, We now proceed to describe its constructionand operation.

Similar letters in the drawings refer to like parts.

This invention consists in joining the upper ends of the legs of a tripod suitable for sustaining blackboards, or, when made smaller, for serving the purpose of a book-rest, in such a manner that the two outer legs may be pivoted in one plane, and the middle leg may be pivoted ina planeat right angles to the former,

and that the three legs may be spread out so as to occupy a tn'angle, or folded together so as to be parallel and in contact.

In the drawingsa a a' represent three wooden bars of suitable dimensions, according to the use required of them, the same being all pivoted at their upper ends to a head, A, of metal or wood, which head has the longitudinal Y libs b l one at each end, to each of which ribs are pivoted the upper ends of the outer legs a a, the said ribs occupying grooves cut in the said legs in the direction of their breadth, and the said ribs being furnished with curved anges b' b' on their upper sides of a width equal to the thickness of the legs c, the upper,

ends of which 'legs the saidianges protect. The legs a a have, therefore, a motion in the same plane, and may be made to approach or recede from each other.

The leg a/ is pivoted in a lug, c, projecting downward from the middle part of the head A, and has a motion in a plane at right angles to the plane of motion of the legs c a.

Hence the three legs a a a may be spread out in tripod form, or the leg a may be turned into the plane of the legs a a, and the latter may be made to approach the leg c' and touch it, and then the three legs will be in a compact form.

B is a shelf for supporting blackboards in the easel or books in tle book-rest, and it is provided at each end with a pin, e e, and in the two outer legs a a are holes e e', dto., similarly placed in each leg, which holes are for the reception of the pins e, yet. so as that the shelfmay be removed at pleasure from the tripod and packed in by itself.

The whole structure may thus be taken apart and made to occupy but little space.

Having thus fully described our invention,

What we claim as new, and desire to secure byLetters Patent, is l As an article of manufacture, the head A provided Wit-h the ribs b b and lugs c, in the manner and for the purpose specified.
