SPECIFICATION forming part of Letters Patent No. 540,434, dated June, 4, 1 895.

Application filed Fehrnary 19, 1895 derial No.'538, Q99. (No model-l To all whom it may concern:

Be it known that I, ADAM WILLIAM GIL FILLAN, a citizen of the United States, residing at Ferndale, in the county of Humboldt and State of California, haveinvented a new and useful'Oamera-Stand, of which the following is a specification.

My invention relates to improvements in that class of camera-stands in which weights are used to properly balance the table, supporting a camera, when the same is being adjusted vertically; and the object of my improvement is to provide a weight and so arrange the same that it will always movein a vertical plane when the table is being adjusted up or down. I attain this object by the mechanism illustrated in theiaccompanying drawings, in which-- Figure 1 represents a perspective view of a camera-stand with my improvements applied thereto. Fig. 2 represents a vertical section of the stand. vFig. 3 represents a vertical section on the line y y, Fig. 2.

Similar letters refer to similar parts) A is a hollow cylinder, provided with feet a a at its lower end. Near the upper endare two slots a a, substantially opposite each other, and over these slots are fastened two slotted plates a a the slots in the plates reg istering with those in the cylinder. In the slots of the plates are j ournaled two grooved pulleys a a I The upper end of thecylinder is internally screw-threaded for the. purpose of receiving the externally screw -threaded collar B, provided with the set-screw b.

O is the standard that is vertically adjustable in the cylinder A, and is held at any desired height by means of the set-screw b. The lower end of the standard is upset or plugged thereby forming a flange that extends out beyond the periphery of the standard. In the periphery of the standard, adjacentto the flange, is formed a groove or channel c, and in this groove is loosely mounted a collar 0', provided with upwardly-extending perforated flanges 0 0 The upper end of the standard is provided with a hollow T-head D, and in this hollow head is loosely mounted a rod (1, provided withscrew-threaded ends on which fit the nuts d d.

E is a yoke, provided with downwardlyprojecting perforated ends e c. This yoke is rigidly mounted on the rod d, in order to turn therewith, and. is held in place by means of the nuts d d. To the upper side of the yoke is attached the table F, uponwhich the camera rests. From the under side of the upper end of the table projects a rod f, that extends down through a perforation in the outer end of an arm f, extending out at a right angle to the T-head.

f is aset-screw located in the side of the outer end of the arm f, and engages the rodf.

G is a weighted collar, that loosely encircles the cylinder A, and to this collar is attached one end of each of the cords,'wires, chains or the like g g. The cords are then passed up over ,the pulleys a (1 down on the inside of the cylinder and. the other ends of the cords are attached to the flanges c c of the collar 0'.

It is obvious that minor changes may be made in the'construction of my device without departing from the spirit of my invention; such, for example, as enlarging or making the upper end of the cylinder A thicker, thereby permitting the grooved pulleys a a to be journaled directly in the slots 01, a, instead of in the plates a a thus dispensing with these plates. In case it is desirable or found necessary, by reason of the weight of the camera, additional weights may be added-and removed without alfecting my construction.

The operation ofmy device will be obvious to any one skilled in the art. Vhen it is desired to adjust the camera to the proper height, or to revolve the same either to the right or left, it is only necessary to release the set-screw b, which will permit the standard O to be turned or raised and held at any desired height by the weight, and by reason of the collarc, to which the Weight is attached, being loosely mounted on the standard the latter can turn without turning the collar; and by reason of the weight encircling the cylinder, it is guided thereby in its vertical movement and prevented from wabbling. In order to adjust the camera to any desired angle, it is only necessary to loosen the setscrew f and the nuts (1' d. v

Having described the invention, I claim- 1. In a camera stand, the combination with the hollow cylinder provided with feet at its lower end, of a vertically-adjustable and revoluble standard mounted in the cylinder and provided at its upper end with a hollow T- head in which is loosely journaled a rod provided with nuts on its ends, and a yoke mounted on the rod and carrying a table, an arm projecting at a right angle from the T head and provided with a set-screw, and a rod extending down from the under side of the table and through the arm, all substantiall as described and shown.

2. In a camera stand, the combination with the stand, of a weighted collar surrounding the upright support and'vertically adjustable thereon, the vertically-adjustable standard, and means for attaching the weight to the standard, substantially as described.

3. In a camera stand, the combination with the stand, of a weighted collar surrounding the upright support and vertically adjustable thereon, the vertically-adjustable standard, and means for attaching the weight to the standard, consisting of cords or wires fastened at one end to the weight and extended up over pulleys in the upright, theother ends being attached to a collar on the lower end of the vertically-adjustable standard, substantially as described and shown.

4:. In a camera stand, the combination with the hollow cylinder provided with feet at its lar loosely mounted in the channel and pro vided with upwardly-extending perforated lugs, a hollow T-head at the upper end of the standard, a rod loosely journaled in the hollow head and provided with removable nuts on its ends, a yoke mounted on the rod and carrying a table, an arm extending at a right angle to the T-head in which is adjustably mounted a rod extending from the table, and a vertically-adjustable weighted collar surrounding the upright support, and cords attached to the weight and collar on the lower end of the veriically-adjustable standard, substantiall y as described and shown.

In testimony that I claim the foregoing as my own I have hereto atlixed my signature in the presence of two witnesses.

ADAM \VILLIAM GILFILLAN.
