SCHOOL-SEAT.

SPECIFICATION forming part of Letters Patent No. 424,713, dated April 1, 1890.

Application filed May 13, 1889. Sen'al No. 310,564.. (No model.)

T 0 on whom it may concern.-

Be it known that I, JOSEPH R. JOHNSON, of the city and State of New York, haveinvented an Improvement in School-Seats, of which the following is a specification.

School-seats have been extensively manufactured in which the back of the seat forms the front and the support for a desk and the seat itself has been hinged, so as to swing up into a vertical position to give the necessary space for the scholars to pass from between the desks into the respective aisles.

My present invention has reference to supporting the intermediate portions of the seats in a row adapted to two or more scholars, and I provide a peculiar]y-constructed bracket for supporting the seats from the back portions thereof and for forming the pivots upon which the seats can be swung up into a vertical position or swung down horizontally, or nearly so.

In the drawings, Figure 1 is a vertical section representing the improved central support at the line y 3 Fig. 2. Fig. 2 is a front elevation with the central support and part of the seats in section at the line at at, Fig. 1. Fig. 3 is an elevation of one of the seat-supports at the side next the seat, and Fig. 4 is a section of a modification. u

At the ends of the seat there are frames A A, usually of metal and having arms or bearings B, to the upper ends of which are provided the metallic supports G of the seat D. These parts are of any usual or desired character, and between the end frames A A and attached to them are the slats E E, forming the back of the seat, and there is a longitudinal rail F between the end frames A, which serves to strengthen and stiffen the seat, and Where there is a desk supported by the same end frames A this longitudinal rail F forms one part of the box beneath the desk, into which books or slates maybe placed. I have represented in the cross-section a desk at G and a top ledge or support H. for the pens and inkstand. These parts, however, being of ordinary character, do not form a necessary portion of my improvement.

The bracket K is adapted to rest against the front of the longitudinal rail F and passes up between. the same and the slats E, and such bracket is permanently screwed to the rail F,

and also to the slats E; hence the vertical por-- tion of this bracket forms a connection between the slats and the longitudinal rail, and the bracket itself is firmly supported by these parts, and such bracket extends downward and forward and terminates in the sockets L. These sockets are adapted to receive the circular portions 2 of the seat-supports M, and in the sockets L are stops i for the stops 5, that project from the circular portions 2 of the supports M, and these stops bear such a relation to each other that when the seat is turned down for use the stop 5, eomingagainst the stop 4, arrests the further downward movement of the seat, and upon the upward movement of the seat the support M is arrested in nearly a vertical position, and these seat-supports M are similar, but in reverse, the projections 2 extending toward each other, so that one is adapted to one side of the socket L and the other to the other side of such socket, and the seats themselves are secured to these supports M; but the ends of the seat are sufficiently distant one from the other to prevent injury to the hands of the scholars as they may be turned up or down.

here but two seats are made use of be tween the end frames there will only be one bracket; but where three seats are employed there will be two brackets, and so on. This construction allows for obtaining the neces sary strength, and any intermediate supports upon the floor are avoided.

Where the brackets are used with a single seat, the two sockets will not both be required on the brackets and the socket at one side can be out off at the line 2; 2, Fig. 1, as illustrated in Fig. 4..

lVhere desired, the seats D D maybe in one length, as shown by dotted lines 10, instead of being in two parts.

I claim as my invention- 1. The combination, with the end frames A,

rail F, and slats E, forming the seat-back, of

IOO

therewith and having the projection 2 and 10 stop 5, entering the socket L, substantially as specified.

Signed by me this 11th day of May, 1889.

JOSEPH R. JOHNSON.
