DROP-S EAT.

SPECIFICATION forming part of Letters Patent No. 674,688, dated May 21, 1901.

Application iiled March 22, 1901. Serial No. 52,292. (No model.) l

T0 a/ZZ whom, it may concern.-

Be it known that I, J AMES PHILIP STEVEN- SON, a citizen of the United States of America, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Drop-Seats,of which the following is a specication.

My invention consists of improvements in automatically-adj ustable supports to a hinged seat for allowing the seat to fold down readily for economizing space and being especially adaptable to use in state-rooms on shipboard and in other rooms where space is limited, as hereinafter described, reference being made to the accompanying drawings, in which- Figure l is a side elevation of a drop-seat with supports contrived in accordance with myinvention, the seat being shown set up for use in solid lines and represented in dotted lines as folded or dropped down. Fig. 2 is a front elevation of part of the seat, represented same as in Fig. l. Fig. 3 is an enlarged detail in side elevation, showing the essential feature of the invention more clearly.

The line a, indicates the side wall of a room, and b the floor-line. The seat-body c is hinged to the side wall at d, so as to drop readily into the position indicated by the dotted lines c', two or more hinges being used, according to the breadth of the seat. Intermediately of the back and front of the seat-body and preferably nearer the latter a stud-pin c projects from each side of said body.

To each side of the seat there is a supporting-leg f, jointed at g to a bracket h, attached to the wall close to the floor, or it may be attached to the door close to the wall, said legs being slotted for the most part of their length, as shown at h, but having at their upper ends a lateral rearward turn t, terminating at j, a little lower than the uppermost extremityc of the substance of the leg, between said terminal j and the part of the slot below the lateral turn. The stud-pins are engaged in these slots,respectively,and spring-keys Zand washers fm are employed to prevent escape of the legs. The lateral partz'of the slot is widened a little at the turn from the part h, and the upper wall is in the form of anarch, so that upthrusting the studs against it from either extremity tends to center the studs in the parts t' of the slots. It will be seen that when the studs e are lodged in the extremities j of the slots i below extremities k the weight of the seat and the gravitating action of the legs keep the legs in position.

Lifting the front of the seat raises the studs e out of their seats in the lateral slots i and against the upper Walls of said slots, tending to thrust the upper ends of the legs back, so that by quickly dropping the seat the studs fall into the parts h of the slots, permitting the seat to drop, and at the same time they swing the legs up close to the wall, and by the inertia of the seat they hold the legs in the folded position. If the seat is not quickly dropped after lifting the studs above the extremities k, it may be necessary to press the upper ends of the legs back by hand.

When lifting the dropped seat up into the position for use, the studs striking the upper curved walls of slots i and the gravitating action of the legs automatically lodge the studs in theends of slots t'.

What I claim as my invention is- The combination with the seat-body hinged to its back support suitably for dropping when unsupported at the front, and having a projecting stud-pin at each side, of supportinglegs for the front jointed at their lower ends in the vertical plane of the seat-hinges or thereabout and having the slots for the studpins backwardly and downwardly turned at. the upper ends of the legs to form seats for the studs lower than the extremities lo, between said seats and the parts h of the slots, and said studs engaged in said slots.

Signed at New York cit-y, New York, this 20th day of March, 1901.

JAMES PHILIP STEVENSON.
