TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, RICHARD F. BRIGGS, of Amesbury, in the county of Essex, and State of Massachusetts, have invented an improved Folding Seat for Carriage Bodies; and I do hereby declare that the same is fully described and represented in the following specification and accompanying drawings, of wh'ich Figure 1 is a side view, with the seat in its upright position.

Figure 2 is a side view with the scat folded against the dasher. V

Figure 3 is a side view, with the scat folded back in the centre of vthe body.

In the drawings I have represented a carriage body such as is ordinarily used on oneseated vehicles, with my improvements applied to it.

The nature of my invention or improvement consists in so supporting the seat that it may be folded against the dasher or back into the centre of the body, or maintain an upright position, by means of two stationary supports extending upright from the sill of the body, one to each end of the back part of the seat, and by two supports attached by movable joints to the front of the seat at suflicient distance apart so they may be enclosed or pass by the above-mentioned upright supports, said front supports being attached to the sill of the body by movable joints at a point to the rear of a. vertical line passing through the centre of the seat when in its upright position, thus enabling the seat to pass over the upright stationary supports at the back thereof, when it is folded back into the centre of the body. The seat is secured in its upright position by means of a frictionplate or laceextending across and under each end of the seat, said plate having a slot out across at the rear cndothcreof, which is received by a corresponding slot in-thc top ofthc upright stationary supports above mentioned The construction, arrangement, and operation of my invention 1 will proceed to explain, reference being had to theaccompanying drawings, in which similar letters represent similar parts.

Letter :1, the seat. Letter 71, one of the front supports of seat a. Letter 0, one of the rear stationary supports of seat a. Letter (1, the slotted friction-plate secured across the'end-of seat a. Letter 0, the pinion by which support I) is attached to seat a. Letter f, the pinion by which support b is attached to the sill of the body. Letter 5 the slot in friction-plate (1. Letter 71, the slot in upright stationary support a, which receives the slot in friction-plate d.

In the construction of my folding seat I attach front support b, by means of pinion e, to the front of seat a, at a point distant from the end thereof, so .s to allow support I; to clear or pass by stationary upright c. I

- also attach'thc lower end of support b to the sill of the body, by means of pinion f, at a point slightly to the rear of a vertical line passing through the centre of seat a, when in its upright position. Pinion e is firmly secured to seat a, and .pinion f to the sill of the body, and they are the points on which support 6 turns when the seat is folded to the front or fear. I secure stationary upright support a to the sill of the body, at a point distant from pinionf slightly less than one-half of the width of seat a, and further from the centre of the body than pinion f, so that when the seat is folded back, support Z; will conic inside of support a. I cut a slot in the. top of' support-c, to receive a slot in friction-plate d, to be hereinafter described. I secure friction-plate d to the end of seat a, said plate being firmly riveted thereto, and containing a slot at the rear end thereof corresponding to the slot in support 0. The slot in friction-plate d, represented in the drawing by letter g, and the slot in upright support 0, represented by letter l1, when pressed together, give firmness and stability to the seat in its upright position. I

In this description of the construction and arrangement of myfolding seat I have confined myself to the mechanism required to operate one end only; the other being the exact duplicate, I have avoided its description as much as possible.

The operation is as follows: The seat being in its upright position, it can be folded against the dasher by slightly elevating thelback part of, theseat sufiicient to disengage the slots g and h, and by its own weight it will fold up against the dasher. The seat can he put in its erect position by raising it until the friction-plates strike the statioiiary uprights, when the slots will readily meet, and secure the seat firmly. To fold the seat I back into the centre of the body, disengage the slots by raising the back of the seat, and throw it back, which will permit a second or back seat to be drawn forward and used as a one-seated carriage.

l: have not dcscribed the second or back seat, as I lay no claim to that; but what I claim, and desire to secure by Letters Patent, is- I v The combination andhrrangement of the support I), slotted friction-plate d, and slotted upright support 0, substantially as described for the purpose herein set forth.

RICHARD F. BRIGGS.
