SPECIFICATION forming part of Letters Patent No. 371,402, dated October 11, 1887.

I Application filed May 12, 1887. Serial No. 231,943. (No model.)

To all whom it may concern:

Be it known that I, CATHERINE A. WIL- LIAMSON, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Seats, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which Figure I is a front elevation or view of my improved seat, showing two back-supports. Fig. II is a rear view or elevation of same. Fig. III is a side elevation. Fig. IV is a side elevation showing the seat proper turned up into non-using position. Fig. V is a vertical section through one of the back rests or supports. Fig. VI is a transverse section of same. Fig. VII is a perspective view of a seat provided with my improvement.

My invention relates to certain improvements in seats; and it consists in features of noveltyhereinafter fully described,and pointed out in the claims.

Referring to the drawings, 1 represents the frame, to which is pivoted at 2 the seat proper, 3, which may be turned down into using position, as shown in Figs. I, III, and VII, or which may be turned up into non-using position out of the way, as shown in Fig. IV. \Vhen the seat is intended for school purposes, it is provided at its top with a table, 4, having an ink-well, 5, and a leaf, 6, the leaf being hinged at 7 and adapted to fold down into the position shown in Fig. IV,to close the mouth of the book-receptacle S, and may be provided with a lock, 9, by which it may be secured in its lower position, to prevent the removal of books, &c. The book-receptacle is formed by the upper ends of the frame 1, by the top 4, and by a shelf, 10. The leaf is supported in its upper position by notched racks 11, secured to the leaf and engaging lugs 12 on the frame. (See Fig. III.) It will thus be seen that by lifting the outer edge of the leaf it will be automatically supported in its using position, and by simply lifting upwardly on the leaf the notched bars will be disengaged from the teeth 12, and the leaf can then be lowered to close the book-receptacle. To permit of the leaf being raised to disengage the racks from the teeth 12, I slot the frame at 13, in which slots the pivot-pins 7 (that hinge the leaf to the frame) fit. WVhen the leaf is raised, these pins move upwardly in the slots, permitting of the disengagement of the racks from the catches.

14 represents arms or bars pivoted at 15 to the seats-3, and which are connected at their lower ends by a round or bar, 25, forming a foot-rest for the occupant of the seat. The arms 14 are connected by bars 16 to the frame 1 of the seat, the bars 16 being pivoted to the frame at 17 and to the arms 14 at 18. When the seat proper is folded as shown in Fig. IV, thisfoot-rest is likewise folded as shown in Fig. IV, this being permitted by the pivoted connection of the arms 14 with the seat proper and the pivoted connection of the bars 16 with the arms and with the frame 1. The foot-rest is thusfolded up out of the way when the seat is folded up.

To provide each seat with a foot-rest for the occupant of the next seat behind, I pivot arms 20 at their inner ends to the frame 1 at 21, and connect the arms at their outer ends by rounds or bars 22. I have shown two of these rounds 22. One only may be used, if desired. When this foot-rest is in its lower position, the arms 20 rest against pins 23 in the frame 1, as shown in Figs. III and VII, and the foot-rest may be folded up out of the way when it is not in use, as shown in Fig. IV. The seats are thus provided with a rear as well as a front footrest, the rear foot-rest being used, as stated, by the occupant of the scat behind the one having this foot-rest. Y

30 represents a back-support secured immediately in front and to the back proper, 31, of the seat. I have shown the/seat provided with two of these supports; but it is evident that one only could be used, if desired, and that it could be used on any form of seat. Each backrest has a portion, 32, to support the spine of the back and a portion, 33, to support the shoulders. It is secured to the back 31 by means of a spring-plate, 34, and a bolt or rivet, 35. The object of thus securing the support to the back is to allow it to adjust itself to the form of the occupant of the seat, so that if a small person is occupying the seat the lower part of the support will (when pressure is brought upon it) tilt inwardly and the upper part outwardly, as shown by dotted lines, Fig. IV, and if a larger person is occupying the seat it will adjust itself in the other direction.

I have shown the plate 34 and bolt 35 as one means for connecting the support to the back;

but other equivalent means could be used which will allow the support to adjust itself, as stated. The back proper limits the oscillation of the back-support, and thus prevents the latter from being oscillated so far as to weaken the spring and perhaps break it.

I prefer to perforate the back, as shown, to permit the circulation of air. 7

The parts 32 and 33 are connected by an intervening Web, 38. A longitudinal section of one of these supports is shown in Fig. V and a transverse section is shown in Fig. "VI. By the use of this device the entire back of the occupant in the seat is supported at all times, and by making the support adjustable it accommodates itself to occupants of different sizes.

I claim as my invention 1. In a seat, the combination of the frame, table located on top of the frame, shelf located beneath the table, leaf hinged to the frame, whereby it is adapted to be swung up in the same plane as the table, so that it can be used in connection therewith as a writing-desk, and racks for holding the leaf in its upper position, the leaf beingehinged to the frame by means of pins thereon entering slots in the frame to permit of the leaf being raised to disengage the racks from their retaining-notches, whereby the leaf is adapted to close the space between the shelf and table, substantially as set forth. 7

2. In a seat, in combination with a frame, the seat proper, 3, and a foot-rest consisting of depending arms 14, having, hinge-connection with the seat near its front, round or bar 25, connecting them together at their lower ends and affording a rest for the feet, and bars 16, hinged, respectively, to the frame and to the arms 14 near their mid-lengths, the foot-rest being adapted to be folded up with the seat, substantially as set forth.

' 3. The combination, in a seat, of a backsupport consisting of a lower portion, 32, upper ortion, 33, web 38, and an elastic strap, 34., the support being connected to the back proper of the seat by means of a bolt, 35, pass
