`.To all wl/om'z'zi may Concern:

iUNrre Strains arentrtree,



Specilication forming part of Letters lfatent No. 42,279, dated April 172, 1864.

Be it known that I, R. vll. ])OU(.LAS, ol' lleveland, in the county ot' Cuyahoga and State of Ohio, have invented new and useful Improvements in Camera-Stands; and 1 do hereby declare that the following; is a i'ull and eomplete description oi' the construction and operation ofthe saine, refe: ence being;` had to lthe aeconi anine drawin s nlakiiw' wartI of this specification, in Which- Figure lis a side view. Figz is an end View, and Fig.- 3 vis adetaehed part.

Like letters denote like parts in the ditlerent views:

The frame or legs Whiehsupport the table and its attachments are shown at A A A", There are three in number, and are connected at the bottom by bars A and atthe top by the platform O.

The table uponI which the camera. is placed yin takin g the picture is shown at B and is hinged to theupper end ot' the standards 4F F',

which are united at the bottoni, and to' those shown at D G; The standard G is hinged at.

upon the outside of vthe platform O, and the standards D and G pass through niortises in the platform O. The standard l) passes freely through a mortise in the Gross-bar H, and to which it is hinged at b. rlhe lever C is hinged to the arm E at a, and to the standard Dat n'.

The l'iinges that unite the several standards tothe table are shown at el.

In the standard D area seriesofholes. (Shown at J,Fig. 2.) A pi1'1,K,Workingin guides upon the top of theplatforni O, is shoved into either of these holes, in order to secure the table at any desired height. The springL is for keep ine` the pin in place. A brace, M, one end of which is secured to the end of the table-leaf and the other to the upper end ofthe standard F' by means of a slot and thumb screw., (show-n at 'N,) serves to secure the table at. any desired angle, as indicated by the dotted lines I I. By loosening' the thumb-screw N, the table B can be set at any desired angle andthere secured,

and when thus' set can be elevated or depressed .by raisin g o r lowering the levert); and secured by shoving in the pin K. Either or both. adjustments can. be made at the same time. These 'ariousmovements are readily madeby theV operator while adjusting;` the foeusfof the l do not broadly claim the use ot a hinged.;

lever for adjusting,r the table, but contine my claim to such arrangement of the lever as will give the table a Vertical and not an obliqne'ly upward and'doivnvvard motion.

Having' thus full y described my iuvjention,

what] elaim, and' desire to vsecure by Letters Patent of the United States, is y I1.- 'lhe tablel3, standards F, F', D,end Gr, and

cross-bars"..ll, when hinged together, as and l for the purpose specified.

2. The use of the hinged lever C, for giving the table a vertical motion, substantially as described.
