SPECIFICATION forming part of Letters Patent No. 424,572, dated April 1, 1890.

Application filed November 25, 1889. Serial No. 331,537. (No model.)

To aZZ whom it may concern:

Be it known that I, ROBERT F. PAINTER, a citizen of the United States, residing at Greenfield, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Canopy-Holders, of which the following is a specification.

My invention relates to canopydiolders, and has reference more particularly to that class of devices in which a divided hollow sphere or ball is mounted in a divided holder orsupport, a single clamping device being used to clamp the two parts of the sphere upon the canopy-rod and the holder or support upon the sphere.

In the drawings, Figure l is a perspective View of my improved holder; Fig. 2, a horizontal sectional view; Fig. 3, a vertical sectional view from front to rear on the line 93x, Fig. 2, Fig. 4, a vertical sectional View on the line y y, Fig. 2; and Fig. 5, a perspective view of the parts separated.

The holder comprises a horizontallydisposed band or ring A and suitable attachingarms B, which latter are cast integral with that part of the ring to be secured to the vehicle. The ring or band is divided transversely at its middle to forni two clampingsections a and Z7, whose inner faces conform to the outer face of the divided sphere or ball C, carrying the rod D. The section a, to which the attaching-arms are secured, is provided with teats c to engage corresponding sockets or depressions CZ in the section b at their point of meeting, in order to assist in maintaining the two sections of the ring or band in the same horizontal plane, the section b being also provided with a short tubular neck or extension e axially in line with the band.

The divided sphere or ball C is hollow and is made up of two semi-spherical sections f and g, which are duplicates of each other, the

-two sections being each provided on their meeting edges with semicircular notches 7i to receive and seat the rod D. Each section f and g is further provided with an elongated slot t', through which passes the bolt or stem E, forming a part of the clamping devices, and with a teatj and socket or depression lo, which serve to keep the two sections in such position that the notch h of one section shall be opposite the corresponding notch of the other section. Bolt E is provided with a T-shaped head Z, which bears against the outer face of ring-section a, and with a stem m, which passes freely through the tubular extension or neck e of ring-section b, the said stem being threaded outside of or beyond the neck to receive a thumb-nut F. It will be noted that the bolt E passes around the canopy-rod D, and in order to permit the insertion of the bolt through the ringsection a the latter is made with an opening or slot n in its rear face.

With the parts thus constructed and arranged it will be seen that by loosening the thumb-screw the parts a ZJ of the band or ring are released, as are also the parts f g of the ball. After the rod D is inserted the thumbscrew is turned, so as to tighten or draw the two part-s of the band or ring together upon the sphere or ball, this action also forcing the two parts-of the sphere or ball together upon the rod, thereby effectually clamping not only the rod in the sphere, but also clamping the sphere in position. The sphere or ball projects above and below the band or ring, thereby permitting the rod carried by the ball to be given any desired inclination backward or forward, sidewise, or in any intermediate direction, the slots t' in the ball-sections allowing of this freedom of motion when the thumb screw is released. It will also be noted that the rod D is capable of a vertical adjustment relatively to or through the ball or sphere independently of its inclination.

By making the two ball-sections duplicates of each other the cost of the fixture is material] y lessened.

No broad claim is made herein to a divided sphere nor to a divided support, as these fea- IOO a clamping device serving to bind the parts of the bail upon the rod and the ring or band upon the bail.

3. In combination with a divided ring` or band and a divided bali7 a bolt passing th rough the ball and ring` and serving to clamp the parts together.

4. In combination with band-sections ce and b, the former having` a yslot n, bali-seciionsf and g, each provided with a slot i, a boit E,

passing; through the slots n and 1l z' and provided With a head l, and a nut F, applied to the threaded end of the boit.

5. In combination with a divided supported ring or band and a clamping device, the ball 0r sphere comprising two parts f and g, each of said parts f g being' provided with a teatj, sockets 7i and k, and a slot fi.

6. In combination with a divided bali or spherevand a clamping' device, a divided ring or band comprising,1 tWo sections a and b, one of said sections being provided with a teat c and the other with socket d.

In Witness whereof I hereunto set my hand in the presence of tWo Witnesses.
