Specification of Letters Patent.

Patented May 1, 1917.

Application filed July 20, 1915. Serial No. 40,841.

To all whom it may concern:

Be it known that I, JOHN H. NIENSTADT, a citizen of the United States, residing at Brooklyn in the county of Kings and State of New York, have invented certain new and useful Improvements in Attachable Automobile-Seats, of which the following is a specification. V

The invention has for an object to provide a seat which may be attached to motor vehicles and detached without marring the finish and without requiring any special permanent fittings or structural elements incorporated on the vehicle. It is an important aim to give such a device which may be located without the body of the vehicle, and is especially adapted to be mounted on the usual running board of such vehicles. A further object is to provide attaching and supporting means for such a seat which will be strong and safe in operation, and which may be quickly attached or detached without the use of tools. It is a purpose also to enable the storage of the appliance in a small space, and to adapt it to convenient use and storage in the body of the usual motor vehicle of the passenger carrying kind.

Additional objects, advantages and features of invention will appear from the construction, arrangement and combination of parts hereinafter described and shown in the drawings, where Figure 1 is a fragmentary side view of one embodiment of my invention attached to a vehicle,

Fig. 2 is a rear view thereof Fig. 3 is a view on the line 3-3 of Fig. 2, looking downwardly.

Fig. 4 is a detail of a modification.

There is illustrated a portion of a motor vehicle including the running board 10 which may be of any customary construction. Engaged upon the running board there is a removable seat 11, comprising a base 12, a leg 13 and the chair portion 14. The base comprises a foot piece 15, having longitudinal forward and rearward extensions 16 engaged upon the upper side of the board 10, and an inwardly extending lateral arm 17, which may also engage the upper side of the board 10, but is also provided with a series of thumb screws 18 to be screwed against the board. From the outer side of the foot piece there is extended a yoke 19, U-shaped and alined with the arm 17 The upper side of the yoke lies on the same level with the arm 17, and its lower arm is spaced therebeneath sufficiently to receive the running board freely therein under the foot piece. The bight of the yoke lies a suflicient distance outwardly of the extensions 16 to per mit the latter to be adjusted well inward of the outer edge of the running board. Centrally of the foot piece an integral upstanding cylindrical stud 20 is formed thereon. The lower arm of the yoke 19 is provided with a number of thumb screws 21 to engage the under side of the running board to securely hold the base in place.

The leg 13 comprises a piece of steel tubing of suitable weight, the inner measurement of which is sufiicient to permit it to engage snugly over the stud 20 so that it may slide down against the foot piece. In its upper part a series of opposed registered openings 22 are formed therein spaced longitudinally of the tube.

The chair comprises a bottom plate 23,

upon which a cushion 24E of any suitable kind is built, having a low side and back rail 25 therearound. To the under side of this plate there is secured a stud 26 having a foot plate portion 27 bolted or riveted to the plate 23, or otherwise connected thereto. The stud 26 fits snugly in the upper end of the leg 13, as will be understood. It is provided with a transverse opening therethrough which may be registered with various openings in the leg, to receive a pin 28 commonly engaged through the leg and stud, by which the chair is detachably secured on the leg and its adjust ment vertically also made possible. The pin is secured to the chair by a small chain 29, to prevent its loss. If considered preferable the leg may be made of a solid bar, and suitable sockets formed in parts on the chair and base, in place of the studs, this being sufficiently obvious to require no illustration. Also, the chair stud may be threaded into the leg as at 30 in Fig. 4, so that the latter may be screwed thereon for retention and adjustment.

The number of thumb screws in the base may be increased as desired, it being possible to provide them in the extensions 16 and upper part of the yoke, so that if a running board has an irregular surface snug engagement of the base thereon may be assured.

Various other modifications of the inven- .tion are possible in the embodiment of the invention Within the scope of the claim, Which I make as follows:

A seat for running boards of motor vehicles for the purposes described, comprising a foot piece having an arm adapted to lie transversely of a foot board, devices carried thereby to impinge upon a board, a member extended from the outer part thereof and spaced therebeloW positioned and shaped for engagement beneath the running board, clamping devices in the last named member, said impinging and clamping devices including members spaced from each other whereby rotation of the foot piece will be prevented, an upstanding member formed on the said arms near its outer part but located to stand a distance Within the edge of an engaged board, extensions on said seat to be disposed longitudinally of an engaged board upon the upper side, a seat, and detachable supporting connections between the seat and said upstanding member.

In testimony whereof I have aflixed my signature in presence of tWo Witnesses.
