IMPROVEMENT IN SCHOOL-DESKS AND SEATS.

The Schedule zeferxed to in these Letters Patent and making part of the same. 7

To whom. 'it 17mg concern:

Be it known that I, HENRY G. SELLMAN, .of North Newburg, in the county of Shiawassee and State of Michigan, have invented a new and useful Improvement in Folding School-Seats and Desks; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which Figure 1 is a side elevation of my improved hinged school-seat frame in its normal position, and

Figure is a similar view of the same, showing the desk and seat raised.

Like letters indicate like parts in each figure.

This invention has for its object the construction of combined school-desks and seats in such a manner that the desk as well as the seat maybe tilted up to give additional room between desks when required.

The invention consists in making the iron standards with a hinge below the desk portion, and in connectthe tiltingdeskwill also be tilted up; and in the 'noveland peculiar arrangement of its various parts, as more fully hereinafter set forth.

In the drawing- A A represent the main end standards of a schooldesk, forming theends-thereof, usually cast in one piece; but in the present case the standards are made in two sections hinged together at a, just below the hook-shelf, under the desk top.

At the lower end of the standard is a leg, I), which, Bvith the lower end of the standard, is secured to the cor. 1

c is the ledge or bracket which supports one end of the desk top, and

d is a similar flange orledge below it, which supports the end of a book-shelf below the desk top.

B is a bracket on the front side of the standard, in which, is pivoted the seat-arm 0, so arranged as to foldup against the front of the'desk, which forms its back.

0n the front edge of each standard is a boss, 0, against the under side of which the rear end, of the seat-arm bears when lowered to a horizontal position and shelf, will be tilted up, as shown in fig. 2, which gives ample room to the scholar to practice class calisthenics, as well as to afford superior facilities for sweeping and-cleaning the floor under the desks.

In order to relieve the seat-arms from the weight of the desk top I forge or cast the radius-bars with a lug, n, which bears upon a stud, h, on thestandard when the desk top is lowered. I

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

arm 0 and the ledge (l of the'upper section A of the standard, being pivoted thereto, as and for the purposes herein set forth.
