TRIPOD OR STAND.

SPECIFICATION forming part of Letters Patent No. 697,147, dated April 8, 1902.

Application filed August 9,1901. Serial No. 71,453. (No model.)

To (bi/Z whom, it may con-007%:

Beitknown that I, CLARENCE W. HOWARD, a citizen of the United States,residing at Kirkwood, in the county of \Varren and State of Illinois, have invented a new and useful Tripod or Stand, of which the following is a clear, full, and exact description.

My invention relates to tripods or stands adapted to serve as supports for photographic cameras,snrveyinginstruments,and otherapparatus, and has for its object to provide a simple construction by which the tripod-legs when spread maybe securely braced and when folded may be securely fastened together. The mechanism in which I embody my invention and by whichI accomplish these purposes will be hereinafterfully described and the features of novelty pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of my tripod supporting a photographic camera, the dotted lines showing the tripod-legs partly closed together. Fig. 2 is an elevation of my tripod, showing the legs folded together, the camera being removed and a cap or handle placed on the head of the tripod. Fig. 3 is a detail of part of the tripod-leg G, showing the connection of the leg-bracin g device therewith. Fig. 4: is a longitudinal section of partof the tripod-leg G, showing the wedge V, which binds the loose sleeve J tightly on the leg. Fig. 5 is a cross-section of the leg G, taken on line 5 5 of Fig. 3. Fig. 6 is a cross-section of the leg I, taken on line 6 6 of Fig. 1.

In my tripod the legs G, H, and I are preferably made of round metaltubing and preferably attached to the tripod-head A by spring members F. The head A has, preferably, the ordinary socket and ball B, carrying the shank O, to which the camera D is attached in the ordinary manner. The head may also be f urnished with a cap or handle W to be attached to the head when the tripod is not in use, as shown in Fig. 2, preferably by being screwed on the head A. The legs G, H, and I are hollow and contain extension legs or rods U, which may be drawn out or in and are preferably held in place by loose sleeves Q, which when slid down on the legs compress the split lower ends thereof tightly on the extensionrods.

My improved spreading-brace for the legs consists of a loose sleeve J on one of the legs G, to which sleeve are pivoted at K K the rods or arms L and X. The arm L is pivoted at its other end to the leg I at Y, and the arm X is pivoted at its other end to the leg II at Z. The arm M is pivoted at either end to the legs II and I, respectively, at N and N and is joint-' erably formed in the shape of the wedge V,

which binds the sleeve tightly in position.

One of the extension-rods U has attached thereto and near its lower end a binding de vice R for securely holding the legs together when the tripod is folded, having the rings S and T, each ring adapted to tightly hold the lower end of one of the extension-rods of the other legs. When the legs are folded together, the extension-rods U in the legs G and H are pushed in and the extension-rod carrying the device R is drawn out of leg I sufiiciently to throw the device R farther from the head A than the ends of the extension-rods in legs G and H. Then the extensionrod U being pushed in the leg I the rings S and T pass over and around the lower ends of the extension-rods of the other legs G and H, and thus all the legs are tightly held together.

I have given the preferred form of construction of my invention; but it will be understood that I do not confine myself to such specific construction above detailed, and shown in the drawings, but reserve the right to use any suitable construction to carry out my invention, particularly pointed out in the claims.

I clain1 1. A tripod or stand consisting of a head, legs, and a device for bracing the legs when spread which consists of a rod or arm pivoted Ice sleeve and at itsother end to one of the other legs.

3. A tripod or stand consisting of a head, legs, and a device for bracing the legs when spread, which comprises a loose sleeve adaptedto slide .up and down 011 one of the legs, and rods or arms each pivoted at one end to the sleeve, one of the rods or arms pivoted at its other end to a second leg of the tripod,

, and the other arm or rod pivoted at its other end to the third leg of the tripod.

4. A tripod or stand consisting of a head, legs, and a device for bracing the legs when spread, which comprises a loose sleeve adapted to slide up and down on one of the legs, and rods or arms each pivoted at one end to the sleeve, one of the arms or rods pivoted at 5. A tripod or stand comprising ahead;

legs G, H, I; the leg I having the extension rod or member U telescoped in said legIand slidable longitudinally therein; and on said extension-rod near its lower end a member comprising the rings S and T, said rings adapted to tightly inclose or enclasp the lower ends of the other legs G, H, when the legs are folded together and said extension-rod is pushed in, and adapted to release said legs G, H, when said extension-rod is drawn outward, substantially as and for the purpose described.

In testimony whereof I have signed my name in the presence of two subscribing Witnesses.

CLARENCE W. HOVARD.
