IMPROVEMENT IN TRIPOD-HEADS FOR CAMERA-STANDS.
Specification forming part of Letters Patent No. 176,692, dated April 25, 1876 application filed I March 22, 1876.
To all whoma't may concern Be it known that I, ANDREW J. RUssELL, of the city and Stateof New York, have invented an Improvement in-Tripod-Heads for Camera-Stands, &c., of which the following is a specification Circular and triangular tripod-heads have been made use of for camerarstands for traveling photographers, &c., and to these heads the threelegs are pivoted so as to be swung more or less apart and accommodate the surface of the ground. These legs are usually each made so as to be disconnected at the upper end from the tripod-head either by withdrawing a pin, or by pressing together the two parts composing the forked upper end of the leg.
My tripod head is adapted to be used with the ordinary legs, but it is made to fold so that'it may occupy very little space in transportation, and may be as firm and rigid as though it were made in one piece.
111 the drawing, Figure 1 is an inverted plan of the'tripod-head as open. Fig. 2 is a similar view of the parts as folded into a small parallel with the bar a, so as to occupy but little space intransportation, as in Fig. 2.
- The bars 0 0, when in the position shown in Fig. 1, occupy a position at right angles to the bar a, and there is a pin 6,- upon one of the bars, entering a hole in the other bar, so as to connect the parts firmly together, but not to interfere with the folding of the bars, as aforesaid.
The pivot-pins f f project from plates 9 that are attached to the outer ends of the bars 0, and the pivot-pins h it upon the plates 70 k at the ends of a are in line with these pivot-pins f, so that two of the legs will be' received between these pins f and h, and the third leg will be received between the pins l I, that project toward each other at the edge of the bar a. These pins 1 Z are upon the plates is, and are the same distance apart, or nearly so, as the pins f and h.
The wood of the bars a and e is removed contiguous to the pins f, h, and I, so as toallow the eyes at the upper ends of the tripodlegs to be sprung over such pins in connecting the legs to the tripod-head.
There is a hole, 0, through the plates I) b for the screw or pin, by which the camera-stand is attached to the tripod-head in any usual manner. V
I claim as my invention- The tripod-head, made of the bar a, plates b b, swinging bars 0, and pivot-pinsf, h, and l, substantially as set forth. v Signedby me this 20th day of March, A. D. 1876.
