SFECIFICATION forming part of Letters Patent No. 552,259, dated December 31, 1895.

Application filed May 20, 1895. Serial No, 549,959. (No model() To all. whom it may concern.-

Be it known that we, SEBASTIAN S. PEcK- TNPAUGH and GEORGE M. OTTO, citizens of the United States, residing' at Oentralia, in

the county of XVood and State of vWisconsin,

have invented certain new and useful Improvements in Camera Boxes or Apparatus; and we do hereby declare that the following is a full, clear, and exact description of the 1o invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to camera boxes or apparatus for enlarging, reducing, and copying pictures; and it has for its object to provide a simple and improved apparatus of this character which will possess advantages in the point of convenience, ease of operation, accuracy, adjustment, effectiveness, and general 2o efficiency, and which can be readily closed or iolded into compact form.

In the drawings, Figure l is a perspective view showing our apparatus in extended position. 2 is a perspective view showing the apparatus partly extended. Eig. 3 is a perspective view showing the apparatus in closed or folded position. Fig. ais a vertical longitudinal sectional view. Figs. 5 and 6 are vert-ical detail transverse sectional views 3o taken, respectively, on the lines l l and 2 2, Eig. at. Eig. 7 is a detail perspective view showing the extension mechanism for the focusing portion of the apparatus. Figs. S, El, and lO are detail sectional views.

Referring' to the drawings, A designates a front extension portion, which carries the ocusing-bellows B, and which is also intended to carry the negative or picture to be enlarged 0r copied.

O designates the negative-holder, which slides vertically within the rim I) oi' the bellows B, and in front of this holder, at a suitable distance thereiroin, is provided a Vfinelyground glass E to insure the transmission of a soit even light upon the negative.

I-Setween the negative-holder C and the front glass E a slot F provided in the top ol' the rim of the bellows I5, in which is set a ground glass G to prevent any shadow from falling upon the negative. These front glasses are adapted to slide or are removable, as desired.

The extension A embodies a horizontal ta ble II, upon which the focusing-bellows is set, and at the front of this table are provided 5 5 two slots or openings I I, adapted to receive the ends of the side bars of a removable horizontal copying extension or table J ,which carries a vertical board K, upon which the small picture to be enlarged or copied is placed. 6o The board K is adjustable longitudinally upon the extension .I with relation to the focusing`- bellows, this adjustment being preferably ixed by means ot' a transverse base-board L, sliding upon the extension J and held in place by spring-clasps M on the under side.

The extension A embodies an upright or standard N, carrying the bellows-table H and resting upon a track O, arranged centrally in the bottoni or base-frame I) of the apparatus. 7o For this purpose the upright N is mounted upon a wheel or roller Q.

The extension A is operated to carry it rearwardly or 'forwardly upon the track by means of a rearwardly extending revoluble lazy- 7 5 tongs connection R, having its front end connected to a wheel or pulley S, mounted upon a frame T, arranged within a carriage-box U, the adjusting mechanism for the extension A being also inclosed within said box. Pro- 8o 'ject-ing from the frame T is a suitable bracket V, within which bears a longitudinally-arranged rotary screw or worin IV, passing through a bracket X at the end of a rearwardly-projecting arm Y, running from the upright N. Fixed upon. the screw is a wheel or pulley Z, connected by cord or band Al with the pulley S. The extension A and its adjusting mechanism are thus carried forwardly and rearwardly with the carriage-box 9o U, and the said extension A is also independentl y adjustable forwardly and rearwardly by the revolution of the lazy-tongs connection R and through the operation of the intervening pulleys and the screw or worm. 9 5

In Fig. 2 of the drawings the focusing-bellows B is shown detached from the connecting-rim R, projecting from the front frame or rim C of the large or main bellows D. This disconnection is made to enable the adroo justment of the lens E of the main bellows, and when the focusing-bellows is connected to the rim B', as shown in Fig. l of the drawings, it is adapted to be fastened in position by means of a clasp. or catch F upon the top of the rim B'.

The large or main extension of the apparatus, which is designated in its entirety by G', comprises the front carriage-box U, upon which is mounted the front rim or bellowsframe C', an upright rear rim or frame Il', and an intervening middle rim or frame l'. The large or main bellows D passes through the middle rim or frame and is secured to each of the end rims or frames C' and lvl', respectively. The middle frame I' is carried upon a carriage J', and the carriages J' and U travel upon tracks K' K', forming the longitudinal side bars of the bottom frame or base P of the apparatus. These side bars or tracks are preferably grooved, as at L', to accommodate the corresponding bottom edge M' of the sliding carriages. The rear rim or frame H' is stationary and is secured to a rear upright frame N.

O' O' designate large vertically-arranged lazy-tongs extensions, which are located under the main bellows D' and are preferably arranged one at each side of the apparatus. The rear ends of the lazy-tongs O' O' are fastened to the rear upright frame N', while their front ends are fastened to the carriage-box U. At about their middle portions these main lazy-tongs are pivotall y connected to the middle carriage J'. This construction and arrangement insures an even and level movement of the several main parts of the apparatus' as the latter is extended during the opening of the lazy-tongs. P' designates a similar horiZontally-arranged lazy-tongs eX- tension, which is provided over the main. bellows D'. The lazy-tongs P' are fastened at their rear ends te the rear rim or frame ll' and at their front ends to the front rim or frame C'. These lazy-tongs are also pivotally connected to the middle frame l'. The top lazy-tongs extension P' thus insures an even and level movement of the apparatus, prevents the middle rim l' and its carriage J' from falling in either direction, and also retains the front rim C' in proper position.

At the rear end of the revoluble lazy-tongs connection R is connected a crank Q', mounted in a suitable bearing-box R', provided in the rear upright frame N'. By operation of this crank the lazy-tongs R may be revolved to adjust the front extension A, as hereinbefore described.

The crank Q' and lazy-tongs R are preferably arranged at one side the center of the apparatus, and centrally mounted in the rear upright frame N is a segmental boXin g S', having a slot or opening T', in which is accommodated awheel or pulley U'. The slot T' opens at the periphery of the box S' to provide for projecting thumb-knobs or handles V' on the periphery of the wheel U', by which knobs the whe'el may be operated. From the wheel U' extends downwardly a rope or cord lV', which runs under a stay-block pulley X', mounted at the base of the frame and near the rear end thereof, and thence the cord or rope runs forwardly and horizontally above the central track O to a wheel or pulley Y', mounted upon the front cross-bar Z' of the bottom frame or base of the apparatus. From this front-end pulley Y' the cord or rope extends rearwardly back to the carriage-box U and is there fastened to a bottom cross-bar or portion of the frame T arranged within the latter. Thus by operating the main wheel or pulley U', which latter serves as a drum for the rope or cord, the large or main extension G' of the apparatus, comprising the large or main bellows and framework and the carriages J and U, which carriage U carries the front extension A, may be thrown out or closed to effect the desired adjustment. ln this operation or adjustment the apparatus is guided or braced by the large lazy-tongs before described, and the front eX- tension A may then be independently adjusted by the operation of the revoluble lazytongs connection R and the intervening screw or worm mechanism, as hereinbefore set forth. The carriage-box U is preferably provided in its top portion with a slotAZ, for the accommodation and guidance of the rearwardly-projecting arm or platform y of the front extension A.

The table ll maybe arranged to slide horizontally and laterally either to the right or left, as the operator may desire, a thumbscrew 312 being provided at the bottom to retain it in adjusted position.

The operation and advantages of our invention will be readily understood by those skilled in the art to which it pertains.

The apparatus is simple and effective in construction and may be conveniently and accurately adjusted as desired to adapt the machine for the different uses and offices for which it is designed..

lWhen the various extensible parts of the appara-tus are folded or contracted into the minimum space which they are designed to occupy, the apparatus may then be folded into compact form, as shown in Fig. 3, by raising the rear portion of the bottom or ba-seframe to the vertical position shown, the side bars or tracks K' K and the central track O being provided with a hinged connection at the points B2 and C2, respectively, to provide for this adjustment. Then the bottom or base-frame is thus folded up, the apparatus is retained in folded position by pivoted side bars or latches D2 .D2 at the top, these latches extending from the side bars K K' to the rear upright frame il'.
