To all w/"wm it may conceive: hinged to the box, as indicated at F in the Be it known that I, FREDERICK W. InvEi-zdrawings. This lid or cover is provided with MORE, a citizen of the United States, residing the arms G, which at their upper ends are 55 at New York, in the county of New York and connected by pivots II to the lens-frame D. State of New York, have invented certain new By thus connecting the lid or cover to the lensand useful Improvements in Cameras; and I frame the lid is made to serve the purpose of do declare the following to be a full, clear, and a leverby which trie lens-frame may be moved exact description of the invention, such as out and in in the act of opening and closing 6o will enable others skilled in the art to which the lid orcover.

The advantage of for its object to so connect the lens-frame this improvement will be apparent to those with the lid or cover of the box that the lid skilled in the art, and especially so as by it or cover will serve as a lever for throwing the the lens is immediately brought in position 7o lens forward in the operation of opening the as the lid or cover is opened for immediate zo lid or cover. I am thus enabled to dispense use without the delay necessary under other with the rack-and-pinion attachments or the forms, where the lens must be brought in posisliding attachments heretofore employed for tion after the lid or cover is opened. advancing the lens after the lid or cover has For the purpose of limiting the movement 75 been opened. of the lens-frame so as to insure the frame To the accomplishment of the foregoing and standing in an upright position when the lens such other objects as may be made to hereinis thrown forward I provide an appropriate after appear I will now give a detailed destop suitably located, so that in the operation scription of an illustration of the means einof opening the lid or cover the lens-frame 8o ployed for the purpose and willv then particwhen it reaches its proper limit will be caused 3o nlarly define by the claims the parts constito bear against this stop, and thus the frame tuting the invention, reference being had to will be prevented from tiltingor assuming a the accompanying drawings, forming a part position other than the vertical.

This brace is used in connection with the stop before described and serves to hold the frame steady in its vertical position When the lid has been opened and the lens advanced in the manner described.

Under my invention as described I am enabled to dispense with parts which have been heretofore employed for throwing the lens forward, and I am also enabled to bring the lens into position at the same time that the lid or cover is opened, so that the camera is ready for instant use immediately upon opening the lid or cover, and I make use of the lid or cover as the lever by which the lens is thrown forward and by which the lens is moved back into the box when not to be used.

I have illustrated and described what I conside/r to be the preferred means for aecomplishing the purposes in view; but I do not limit myself to the particular construction, as changes may be made therein Without departing from the essential features of my invention.

Having described my invention and set forth its merits, what I claim isl. In a folding camera, the eombinationof the lens-frame, the lid or cover, and a connection between it and the lens-frame, to convert the lid or cover into a lever for throwing forward the lens to a fixed position in the operation of openingl the lid or cover substantially as specified.

2. In a folding camera, the combination of the lens-fra1ne,thelid or cover, a connection between it and the lens-fra1ne to convert the lid or cover into a lever for throwing` forward the lens to a fixed position in the operation of opening the lid or cover, and a stop to limit the movement of the lens-frame to an upright position substantially as and for the purposes described.

3. In acamera, the combination of the lensframe, the lid or cover, a connection between it and the lens-frame to convert the lid or cover into a lever for throwing forward the lens to a fixed position in the operation of opening the lid or cover, stop to limit the movement of the lens-frame to an upright position, and a brace for the lens-frame substantially, as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.
