CAMERA-STAN D.

SPECIFICATION forming part of Letters Patent No. 507,807, dated October 31, 1893. Application filed June 24,1893. Serial ITO-478,717. (No model.)

To all whom it may concern:

Be it known that I, JOHN HENRY GREEN, of Ishpeming, in the county of Marquette and State of Michigan, have invented a new and useful Improved Camera-Stand, of which the following is a full, clear, and exact description.

My invention relates to improvements in stands for the support of photographerscameras, and has for its object to provide a novel device of the class mentioned, which will afford means to quickly and conveniently adjust the supported camera, at any desired height or angle of inclination from a horizontal position.

To this end, my invention consists in the construction and combination of parts, as are hereinafter described and claimed.

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

Figure 1 is a perspective viewof the improvement in lowered adjustment. Fig. 2 is a perspective view of the improved camera stand in elevated and inclined adjustment. Fig. 3 is a side View, in section on the line 33 in Fig. 1; and Fig. 4 is a reverse sectional plan view, on the line 4-4: in Fig. 8.

The base piece A of the improved camera stand, is preferably given a triangular form having a suitable area to afford a proper support to parts placed on it. Three stably connected legs a are secured by one end of each to the part A, depending therefrom near its three corners, as represented in Figs. 1' and 2, two of said legs having casters a on their lower terminalsto facilitate the movement of the camera stand; and to further this object, a removable leg a shown by dotted lines in Fig. 2, may be inserted in a socket hole I), that is at an angle of the base piece from which a leg is projected that is not provided with a caster.

From the upper surface of the base piece A, near each of its corners, a tubular standard B is vertically erected, these standards being of equal diameter and length, proportioned to the desired capacity of. the device.

A preferably rectangular carrier frame or plate 0 is provided, from which depends three guide rods B, their upper ends being properly affixed to the carrier plate so as to project therefrom at points which will permit each rod to loosely engage with and reciprocate in one of the hollow standards B.

To insure stability for the parts B, ametal reinforcing frame E is secured on the lower side of the carrier plate 0, at a proper point, as indicated in Fig. 4. Said frame is preferably made triangular in form with cross bars 0, and the guide rods B being firmly attached by their upper ends to the angular corners of the frame E, project downwardly at right angles thereto.

Near the center of the base piece A, a coarse screw cut rod 01, is vertically and rotatably supported, by its journaled engagement with a perforated bracket plate e that is attached to the base piece A, as represented in Fig. 3. Upon the lower portion of the screw rod d, a bevel gear pinion g is secured, and the journal end of said rod projects below the lower face of the pinion, which face is in contact with upper surface of the bracket plate e and serves as a base for the rod d.

There is a guide tube G, secured by its upper end in a perforation centrally formed in the triangular reinforce frame E, where the bars 0 cross each other, as shown in Fig. 4, which tube slides loosely over the screw rod (1 and is provided with a nut h, that is secured in its lower end, and adapted to receive the threaded body of the screw rod that is designed to traverse it,

A shaft 2' is horizontally and rotatably sustained upon the base piece A by the spaced journal boxes is, that are secured on the latter, there being a bevel gear wheel m, of greater diameter than the pinion g, secured on the inner end of shaft 2' and meshed with the pinion. A crank handle '6', is formed on or secured upon the shaft 1', and affords means for the manual rotation of the shaft and the consequent elevation or depression of the carrier plate 0; as the rotation of the screw rod 01 in one direction, will quickly elevate the threaded guide tube Gr and guide rods B, which together maintain the carrier plate in a level condition as it is raised, the reverse movement of said rod lowering the carrier plate, so that by the described mechanism the piece C may be vertically adjusted a height nearly equal to that of the hollow standards B.

On the carrier plate O a rectangular platen I is secured near one of its edges, by the hinges n, that are afiixed by one leaf of each hinge to an edge of the carrier plate, which will permit the free opposite edge of the platen to be elevated and incline its upper surface such a degree as may be necessary.

On the upper surface of the platen I at the edge that is parallel with and near to the hinges n, a ledge 0, is affixed,which is designed to prevent a camera case from slipping 0d of the platen, the ledges 19 along the side edges of the said top surface, being pfovided to retain the camera case from lateral displacement. A coarse threaded adjusting screw 0" is provided which engages a nut block 5, that is secured on the edge portion of the carrier plate 0 which is opposite the hinges it, said screw having a crank handle 1'', for its convenient manipulation.

On the base piece A a locking arm u is pivoted, one end of which may be swung so as to interlock with the teeth of the bevel gear wheel m and prevent its rotation.

The frame pieces '0, w, are secured in proper relative position, on the base piece A and are intended to support in an upright position, the plate-containing box (not shown), while the operator is adjusting the camera and supporting stand for use.

The improved camera stand may be freely moved on the legs at having casters,if elevated slightly at the rear side where the leg that is devoid of a caster is located, and if the entire device is to be moved any distance in a room, the detachable leg a may be inserted in the socket hole b as before mentioned, and thus afford three legs with casters; the length of the leg a being greater than that of the leg without a caster, which Will be elevated so as to avoid touching the floor, when the leg at is in use.

It will be seen that the platen I with a camera on it may be quickly and reliably adjusted for height to suit the height of the person or object to be photographed, and that any desired degree of inclination may be given to the case and its lens, as may be necessary to properly arrange the instrument for use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination in a camera stand, of a base piece A having supporting legs on its lower side, and on its upper side vertical tubular standards B and rotatable screw shaft (1 with a bevel gear at the bottom for turning it; the parallel carrier plate 0, with reinforcing metal frame E on its under side having rigidly attached depending rods B entering the tubular standards and hollow stem or guide tube G with nut encircling the screw shaft, and an adjustable platen I hinged to the plate 0 at one edge and provided with means for adjusting its inclination, substantially as shown and described.
