COLLAPSIBLE TRIPOD.

mam/2e.

Application filed December 2, 1914. Serial No. 875,074.

To all whom it may concern Be it known that we, ARTHUR D. ROBIN- SON and ALFRED P. BOLLER, Jr., citizens of the United States, and residents, respectively, of the borough of Manhattan, city, county, and State of New York, and of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Collapsible Tripods, of which the following is a specification.

The present invention relates generally to tripods and has more particularly reference to tripods which may be used in connection with moving picture machines.

The main object of the invention is to produce a very substantial and rigid structure which is readily collapsible so as to render it easily portable.

With these and other objects in view the invention consists of the features of con.- struction, combination of parts and arrangement of elements as pointed out in the claims appended hereto, a preferred embodiment of which is disclosed in the accompanying specification and drawings.

In said drawings: Figure 1 is a vertical sectional view, with parts removed and broken away, through the standard showing the device collapsed and the legs nested within the standard. Fig. 2 is a fragmentary view, partly broken away, of the stand ard in its working position with the legs in place. Fig. 3 is a sectionalplan view with parts broken away, taken on the line 33 of Fig. 2.

1 indicates a hollow standard for suitably supporting a member such as indicated by 2. At the lower end of said standard there is a collar 3 provided with a plurality of abutment members 4 having saddle portions 5 angularly disposed with respect to the standard. The said collar 3 is provided with ears 6 for the reception of the pivoted clamping means 7 a pivot 8 connecting the ears 6 and the members 7 This pin 8 may be rather loosely fitting if desired. 9 indicate the legs which are adapted to be inserted in the sockets 10 of the clamping members, said legs being held in position in said sockets by means of the clamping screw 11. In use the leg 9 is inserted in the socket portion 10 and secured thereto by means of the member 11 and said clamping means 7 is thereafter swung outwardly until the up- Specification of Letters Patent.

per portion of the leg 9 rests in the saddle portion 5 of the abutment member 4:, at which time the said socket member 10 will be substantially in alinement with the saddle portion 5. It will be observed that said abutment member 4 is under compression and said clamping member 7 is under tension and that the parts are so arranged that the three points of support, consisting of the saddle portion 5, the pivot 8 and the socket portion 10, form the corners of a triangle which may be drawn between said points, as indicated in dotted lines, thereby obtaining a very rigid and substantial support.

When the device is collapsed the legs 9 are nested within the hollow standard 1 and for the purpose of more readily holding said legs in position within the standard, the clamping member 7 may be provided with a projection 12 which serves to confine said legs within the standard when the clamping means are folded back into position as indicated in Fig. 1.

What is claimed is:

1. A collapsible tripod comprising: a hollow standard, removable legs adapted to be clamped to the exterior of the standard when in use and to be nested within the hollow standard when not in use, collapsible clamping means exterior to said standard for removably securing the legs in position for use, and a projection on said clamping means adapted when the latter are collapsed to confine the legs nested within the standard.

2. A collapsible tripod comprising: a standard, a plurality of angularly disposed abutment members on said standard, pivotally supported clamping members on said standard below said abutment members, and legs adapted to be supported by said abutment and clamping members.

3. A collapsible tripod comprising: a standard, a plurality of abutment members each having a saddle angularly disposed with relation to said standard, pivotally supported clamping members on said standard below said abutment members each having a socket angularly disposed with respect to the standard and in alinement with the saddle portion of the abutment members, and legs adapted to be supported by said abutment and clamping members.

4. A collapsible tripod comprising: a standard, a plurality of angularly disposed abutment members on said standard, pivotally supported clamping members on said standard having sockets for the reception of legs below said abutment members, and legs adapted to be supported by said abutment and clamping members, the abutment member, the socket of the clamping member and the pivotal support of the clamping member forming substantially a triangular support.

Signed at New York city, in the county of 10 New York and State of New York, this l ith day of November, A. D. 1914.
