Application filed August 5, 1910. Serial No. 575,839.

.eras; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the reference-numerals marked thereon.

The present invention relates raphy and more particularly to graphic cameras and ithas for its ob ectto provide a simple, cheap and convenient instrument of this character which will be light and compact, the improvements being of such a nature as to commend themselves for use more particularly in folding .and pocket cameras.

Another specific object of the invention is to provide a construction ofiering improved means for adjusting the camera front on the bed for photographing at dif ferent focal distances.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features beii'ig pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a front elevat-ion of a folding pocket camera constructed in accordance with and illustrating one embodiment of my invention, the same being shown in extended position; Fig. 2 is a central vertical section taken therethrough substantially on the line 22 of Fig. 1 from front to rear, but with the parts in folded position taken on the same line 22 of Fig. 1. Fig. 3 is a detail section taken substantially on the line 3-3 of Fig. 1 showing the bed supporting arrangements; Fig. t is a section corresponding to Fig. 2 but with the parts in extended posito photog tion; Fig. 5 is a detail perspective view of the stem for supporting the front on the bed, and Fig. 6 IS a detail plan view of a portion of the bed showing the focusing scale.

Similar reference numerals throughout the several figures indicate the same parts.

As before indicated, the camera of the present embodiment of the invention is of the folding type and comprises a box or body portion 1, a back 2, through which access is obtained to a chamber 3 for the sensitized material and a door or cover 4 at the front, hinged at 5, and serving, when extended, as the camera bed, this part being held in closed position by a suitable catch 6. A tapered, collapsible bellows 7' is connected at its rear or larger end 8 to the body 1 to fold withi rthe latter, as shown in Fig. 2, when the camera is shut and connected at its outer or reduced end, as at 9, to a front 10 that folds against. the bellows, as shown in Patented May 6,1913.

bed or cover is closed the projection 15 oc cupies the lower extremity of the slot, as

shown in Fig. 3, but when the bed is 6X? tended the projection is moved to the head of the slot, as shown in Fig. 4, with the link in a braced position under the influence of a leaf spring 17 carried on the bed and en gaging the link. The link is arranged to support the bed in a forwardly inclined position relatively to the general vertical plane of extent of the body for a purpose that will be hereinafter explained.

At its forward end, just in rear of the lip 18, whichcooperates with the catch 6, the thickness of the bed (that can beotherwise made of relatively thin material) is in creased, as by the superposition of a block 19, and this thickened portion is pierced by a plurality of slots or transversely extending openings 20 forming sockets extending through the bed from side to side. The front 10 is preferably composed of a relatively thin metal plate that of itself conbe released ity of converging leader lines stitutes a lens board to which the lens may be conveniently fitted and which has an ex tension 21 lying in the same plane and forming a stem adapted to fit the sockets 20, selectively, and to thus support the front in an erect position on the bed substantially parallel or in its usual position with regard to the body 1. Inasmuch as the bed has an inclined position, it lies parallel with an ad jacent face of the bellows 7 when the parts are thus assembled and this feature is of great utility both because of the fact that it reduces the bulk of the camera as a whole and because it considerably reduces the height of the front, or at least the distance from the bed to the axis of the lens. F or instance, the same front may be used no matter how extreme the taper of the bellows or the taper of the cone of light projected from the lens which latter governs the shape of the bellows in this respect.

In the present instance, the extension or stem 21 is divided into a pair of relatively rigid tongues 22 and an intermediate resilient tongue 23 slightly less in thickness and provided with a locking shoulder 24:. The stem projects all the way through the bed and when thus inserted in one of the sockets 20, the shoulder 24 on the tongue 23 automatically snaps into cooperation with a locking shoulder 25 formed, in the present instance, by the edge of the socket but may by the fingers of the operator for detaching the front as the tongue is readily accessible for this purpose from the under side of the bed.

The purposein providing a plurality of sockets is, of course, to permit changes in the position of the front for altering the focus of the camera according to the distance of the object from the lens. The sockets 20 are necessarily rather close together and I therefore provide a focusing scale for indicating the particular socket into which the stem should be. inserted for an object at a given distance in which scale, indicated by numeral 26 in Fig. 6, the characters 27 may be spaced a greater distance apart than the sockets to which they refer, such reference being established by a plural- 28, one of which is extended from each character to its respective socket, as shown. This isof advantage both in laying out and manufacturing the scale and in rendering the readiiig thereof more convenient.

It is pointed, out that by constructing the front in the manner shown and described the supporting stem 21 thereof may be made substantially flat to lie in a general plane with the front as a whole and thus when the camera is folded, very little space between the folded bellows and the bed or closure 4 of the bellows when the latter is extended,

a front independent of said supporting means connected to the other end of the bellows and cooperating devices for detachably mounting the front in any of a 'plu rality of upright positions on the bed substantially parallel with the body, comprising a plurality of sockets extending diagonally hrough the bed and a stem, on the front adapted to be inserted within the sockets, selectively.
