TO ALL WHOM IT MAY UONGERN:

Bc it known that I, F. E.`WILKE, of Brooklyn, Kings. county, New York, have invented a new' and improved Photographic Camera-Stand; and I do hereby declare. that the following is' a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the snme,'refcrence being had to the accompanyingfdrawings, forming part of this specification, in which Figure 1 represents a vertical longitudinal section of my improved camera-stand, the plane of section being indicated by the line :v x, fig. 2.

Figure 2 is a vertical cross-section oi' the same, the plane of section being indicated by the line y y, iig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to a new device or support for photographic cameras, which is so constructed that the camera can be raised or lowered and set at any desired angle with the greatest facility and accuracy.

It consists, first, in the use of a' vertical screw, the head of which supports the upper or sliding portion of the support, and which passes through a nut that is arranged in the lowor stationary portion of the support. By turning 'the screw, the upper` portion can be raised or lowered to any desired height, and with it the camera which rests thereon.

My invention consists, second, in the construction and arrangement of the device for setting the camera at an incline. In this a horizontal screw is swivelled into the sliding-frame, and operates a sliding-nut, by which one or more arms which are hinged to the said sliding-frame, and the free endsvof which rest upon said nuts, are moved, so that their free ends are raised and lowered as far as desired. These barsare arranged under the hinged pla-te upon which the camera stands, and the latter is thus operated as desired.

A represents the stationary frame or support of a camera-stand, made of wood or other suitable material in the usual manner. On its inside are arranged vertical grooved or other guides B, in which corresponding tongued or other guides C slide, which are part of the sliding-frame D. Ilin the upper part of the frame A i secured u. crossbar, E, in which a nut, F, is firmly and stationarily secured. G is a vertical screw, made of wood or other suitable material, and is swivelled or'hun'g in a. cross-bar, n, of the sliding-frame, and which its through the nut F, as is clearlyshown in the drawings. On the screw G is mounted a pinion, H, which meshes into a. gear-wheel, I, which is mounted on a'. shaft, J, as shown, The latter-has its bearings in the sliding-frame, and is provided with a crank, b, or other suitable device, whereby it may be easily revolved. Thereby the screw G is turned in the nut, and the distance between the cross-bars E and t can thus be increased or diminished, or the sliding-frame A raised or lowered with ease.

It will `be understood, from the following description, that thc sliding-frame rests upon and is supported only by the screw Gr, and as shoulders c c are formed on the screw above and below .the cross-bar a, it is clear that, as the screw is turned, the sliding-frame must be raised or lowered. By the use of 'the screw, .the camera, which stands upon the-sliding-frame, can be accurately adjusted to any desired height, whilein thel usual camera stands ratchet-wheels are employed, whereby no very great accuracy of adjustment can be obtained. 0n tcp of the. frame D is arranged a horizontal screw, K, which is swivclled to the same in the manner shown in fig. 1,

and which can be turned by a crankior handle, d. L is aslidingnnt,which is fitted around the screw K', and

which is guidedbetwecn grooved pieces e e, which are arranged stationary on the sliding-frame, as is clearly shown in iig. 2, and whichprevent the said nut from revolving, but not frox'nsliding. M.M are bars, which are.

pivoted or hinged hear that end of the frame D in which the screw K is swivelled, their pivotingpoints being at about the same height with theV axis of the screw K. Their free ends rest, upon the nut L, as is clearly'shown Lin iig. 1. N is a plate, which is hinged to the top of the frame 'D on that side which is opposite to that 0n i I which the bars M are pivotcd. The free end of this plate rests upon that of the bars M, as shown in iig. 1. It

will be seen that'lby turning the screw K, so that thc nut L is moved towards the handle of the screw, the free ends of thebars M must be raised, as the nut moves below them towards their pivoting points, increasing their angle of inclination the nearer it approaches the latter. K The free end of the plate N is thus also raised, and its inclination increased, and with it that 'of the camera, which stands upon theplate N. By turning the screw ,K in the opposite direction, the uut will move towards 'the hinges of the plate N, and the latter will thus bebrought nearer' to a. level position.

Having thus described my invention, I claim' as' new, and desire to secure by Letters Patent- 1. The device for raising and lowering the sliding-frameot` a cnmera-sta.nd, which consists of a. vertical 1 screw, G, which is held between theV cross-bends E and a, which are part of the stationary and sliding-frames respectively, said screw being operated by means of gear-Wheels H and. I, and bv c handle, b, on a shaft, J, all v ns sot forth.

2. The `device for placing the plete N, and the camera which is supported by it, into an inclined position, scid device *consisting of the arrangement' und combination with each other of thc screw K, sliding-nut L, pivoted arms M, and hinged plate N, all made and operating substantially as herein shown and described.

3. The raising and lowering device of a camera-stand, in combination with the device for inclining the camera, when the same are made substantially as herein shown an described, and when operated by means of the screws G and K, respectively, as set forth. i WILKE. l
