AUTOMOBILE-CHAIR.

Specification of Letters Patent.

Patented June 27, 1916.

Application filed March 17, 1915. Serial No. 15,009.

To all whom it may concern:

Be it known that I, WILLIAM G. WALL, of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Automobile- Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved motor vehicle seat or chair having simple means whereby it may be bodily shifted in a longitudinal direction and locked in any preferred position, the chair in all positions having a rotary movement.

In the accompanying drawings, Figure 1 is a view in side elevation, and Fig. 2 a top plan view showing a vehicle body of conventional form and chairs arranged in tandem. Fig. 3 is an enlarged view in side elevation of the chair support. Fig. 4 is a top plan view thereof. Fig. 5 is a detail view of one of the clamping arms. Figs. 6 and 7 show, respectively two forms of clamping rails.

Referring to the drawings, the vehicle body 1 is provided with two longitudinally arranged parallel tracks or clamping rails 2 which form guides for chairs 3. These rails are located above and spaced from the floor of the vehicle, and each rail is provided with a flange 4, the lower edge of which forms an engaging surface for clamping arms 5 of each chair.

Thechair support comprises a standard having a central portion 7 and radially disposed supporting legs 8 within the ends of which are mounted bearing rollers 9. Integral with the standard, and at one side of the center thereof, are extensions 10 to which are pivoted the clamping arms 5. Each of the latter is of inverted U-shape, one of its members being elongated and bent back upon itself to form a hook or rail engaging portion 14 to take in the flange 4 of the clamping rail. The lower edge of the latter may be plain, as shown in Fig. 6, or it may be provided with teeth, as indicated in Fig. 7. A stud 15 projecting from the elongated member above'the hook 14 is designed to bear on the upper face of the clamping rail to aid in looking and prevent any accidental disengagement of the hook and rail. The opposite member of each clamp is provided with a swiveled nut 16 with whlch engages a threaded rod 17. The rod has two oppositely threaded portions so that the clamping arms may be turned on their pivots toward and away from each other, longitudinal movement of the rod being prevented by a fixed bearing 18. The rod is shown as provided at one end with a handle 20, and the other end enlarged and of hexagonal form to accommodate a wrench. By turning this rod in one direction the clamping arms will be forced into locking engagement with the edge of the rail and will hold the chair against longitudinal movement. An opposite turn of the rod will free the arms and allow the position of the chair to be altered.

Any preferred form of chair may be used, that shown being of the revolving type, the chair being secured to a plate 25 fitting over the central portion 7 of the chair support, a central post 26 extending through an opening in the support and having a spring 27 interposed between its nutted end and the portion 7 to insure sufficient tension to prevent unnecessary movement of the chair on the support.

It will be apparent that the seating arrangement of an automobile equipped with my improvement may be varied at wild. The chairs may be moved to any predetermined position along the rails and securely held in that position by turning the clutch-controlling rod to lock the clamping arms to the rails. The weight of the chair is taken up wholly by the wheels 10 and there is 11 weight on the rails.

I claim as my invention:

1. The combination with a base having a track, of a chair, a support therefor movable on said base, said support having lateral extensions, clamps pivoted to said extensions and designed to engage said track, and an adjusting rod journaled on said support and engaging said clamps for causing them to bind or release said track.

2. The combination with a base having atrack, said track having a depending flange, of a chair support, a clamping member pivoted to said chair support and formed to engage said track and inclose said flange, and means for turning said clamping member on its pivot to cause it to bind or release said track.

3. The combination with a base having a track, said track having a depending flange,

of a chair support, a clamping member pivclamping members, and an adjusting rod having a fixed bearing in said chair support and also having oppositely threaded portions for engaging said nuts.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

WILLIAM G. WALL. Witnesses:
