,To @ZZ whom t may concern.-
Beit known that we, WILLIAM F. CARLTON and HARVEY WV. LOCKE,citizens of the United States, and residents of the city of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Photographic Cameras, of which the following is a specification, reference bein ghad to the accompanying drawings, in which- Figure l is a side elevation of one of our cameras fully extended and with the swinging back inclined with reference to the base, a part being removed to show construction. Fig. 2 is a top plan of the swinging back, showing it inclined in a vertical plane. Fig. 3 is a top plan view of the adjusting devices of the lens-support, parts being removed to show construction. Fig. 4 is a top plan view of a portion of the swinging back, showing the means for engaging and disengaging the plateholder or roll-holder, parts being removed to exhibit construction. Fig. 5 is a vertical section on the line 5 5 of Fig. 3. Fig. 6 is avertical section of the clamping device on the line G 6 of Fig. 8. Fig. 7 is an elevation of the cam and its handle of the clamping device for the lens-support. Fig. 8 is a vertical section of the swinging and clamping devices on the line S S of Fig. 2, and Fig. 9 is a bottom plan view of the same devices removed from the falling back of the camera.
rlhe object of our invention is to provide a camera having a long range by extending the bellows to the utmost extent which the construction permits, and having various adj ustments hereinafter set forth, and also having simple and effective clamping means for various parts.
Our invention consists in the mechanisms and combinations hereinafter set forth and claimed.
In the drawings, A is a hand-camera box of suitable size, preferably having a side door A and a handle A3.
A3 is the falling front of the camera, hinged to the box A and supported by slotted links a3, one on each side, and having also a medial longitudinal guideway d3. In line with the guideway d3 and within the box A is a similar guideway a', which permits the lens-support B to be moved from the falling front A3 into the interior of the box A and to be capa* ble of direct movement from the guideway a within the box to the guideway a2 on the falling front. The engaging-guides h4 of the lens-support B are so long as to be capable of passing from the guideway a3 to the guideway a' without sidewise displacement and without disengaging from one guideway before fully engaging with the other.
A lens In|- and its attachments are supported by the frame B and may be of any suitable construction. The frame B is suitably arranged for change of the lens. The frame B is supported by means of side posts B2 (see Fig. 3) upon a base B3. This base rests upon a plate B4and is capable of transverse movement thereon by means of a slot in the plate, in which slides a guide-piece h, held therein and to the base B3 by means of a screw h', fastened in a plug b3, which plug is bored transversely and parallel to the line of said slot for the insertion of a cam b4, provided with a handle b5. On turning the handle h5 the cam raises or lowers the plug b3 and presses the plate l) in its slot, whereby the base B3 and the supporting-plate B4 are clamped together.
On turning the handle b5 from the position shown in Fig. 5 the base B3 and plate B4 are loosened with respect to each other, and the base B3 may be moved transversely of the camera, as indicated in dotted lines in Fig. 3, in order to change the transverse alinement of the lens with reference to the sensitiveplate. To the plate B4 is also fastened a bar B3, (see Figs. 5 and 6,) against which, in the form shown, the base B3 moves, as shown in Fig. 3. We provide the following means of clamping the plate B4 longitudinally of the machine. Upon the guides a3 slides a plate a. On the under side of the plates B4 are a pair of clamping-jaws b4 b3, (see Fig. 6,) one of which, as b4, may be stationary and the other of which is movable to and from the edge of the plate d to clamp the same. In a suitable recess in the under side of the bar B3 slides a plate b3, capable of transverse Inovement in the recess. A pin 197 extends upwardly from the movable jaw h5 through a hole in the plate h, and through another perforation in the plate h3 extends the cam B3,
IOO
provided with the handle B7. The lower end of the cam B8 is cut away, as shown in Fig. 7, so that on turning the handle the plate BG may move into the notch bs to unclamp the jaw b5. The turning of the handle Bin either direction into the position shown in Fig. 3, or in line with said position, clamps the bar B5 and also the plate B4 to the sliding plate a, while a position between these two permits a sidewise movement of the bar b and allows the jaw b5 to unclamp. An adjusting-screw b9 passes through an upturned edge of the plate h6 and presses against the pin bi in order to adjust the clamping action of the jaw b5 with reference to the edge of the plate a and the movement of the handle B7 and in order to take up wear. If the handle B7 is turned to loosen the jaw b5, the lens-support B may be freely moved backward and forward upon the plate a or into the box A and upon the guide a. OE course either or both of said jaws may be operated by the plate b by providing pins for either or both jaws and connecting either or both with the plate.
On the under side of the plate a is a longitudinal rack a4, Fig. 5, with which meshes a pinion a5 for slowly focusing the lens when its support is clamped to the plate ce. The pinion ai is long and is set in suitable bearings to be movable transversely of the rack without disengaging therefrom and is connected to a milled head a7, Fig. 3, which is capable of being pushed into a cavity a2 in the edge of the falling front A3, Figs. l and 3, whenever the front A3 is to be closed, but is capable of being pulled out therefrom in order that the head a7 may be properly grasped in order to focus the camera. The length of the pinion a5 permits the latter to remain in engagement with the rack a4 in either position of the head a7, as shown in dotted and full lines in Fig. 3. Te thus provide simple and ei'iicient means of moving and clamping the lens-support B either longitudinally or transversely of the camera for quick adjustment thereof, and we also provide simple means for the slow adjustment or accurate focusing thereof, all of which devices are so constructed that the device is capable of being compactly packed in a hand-ease.
The back D of the camera-box is hinged thereto and is arranged to drop to a position in line with the bottom of said box, being guided and supported by the links D/, one on each side. The falling back D is provided with recessed longitudinal guideways D2, (see Fig. 8,) in which slides a bar D3, which supports the frame D4 for the swinging back, as herein after described. Corresponding guideways D20 in the box A permit the swinging back 1o be slid from the falling back D into the camera-box and to be fastened therein. \Vhen the swinging back isinside the camerabox and the falling back is closed, the device becomes an ordinary hand-camera, and the door Al is used to obtain access to the swinging back. The bottom rail of the frame D4 is fastened to the bar D2 by the screw or pin CZ, upon which the frame D4 is capable of turning as a vertical pivot. (See Fig. 9.) The bellows C extends from the lens-support B to the swinging back, and, by means of the slides or guides D2and a2 for the swinging back and for the lens-support, these two parts are separable to the utmost extent which the extreme length of the falling front A3 and the falling back D can permit. Our camera is therefore capable of great range on account of this great extensibilityof the bellows C, and at the same time is capable of being packed Very compactly into the box A, and may be used as a hand-camera or as a tripod-camera, and with a long-focus or a short-focus lens.
To the frame D4 is fastened a pair of arms DI", one of which is shown in dotted lines in Fig. l, one arm being on each side of the frame, and to these arms are pivoted by horizontal pivots LZ the supplementaryframe D6, which is therefore capable of swinging on a horizontal axis formed by the pivots CZ', which is at right angles to the axis (Z on which the frame D4 turns. This gives a universal adjustment to the focusing-plate, plate-holder, or rollerholder, which are attached to and supported by the frame D6. The frame DG has a curved rack d6 thereon, and curved upon a radius drawn from the pivot (Zv. A spring (Z5, provided with a suitable handle, is attached to the frame D4 and is provided with a tooth (Z4, which engages with the rack (ZG. By pressing the spring Z5 away from the rack the tooth (Z4 is disengaged therefrom, the frame D6 may be turned upon its pivots (Z, and on releasing the spring (Z5 may be locked in any suitable angle to the horizontal.
rlhe frame D4 has a supplementary rearward extension consisting of the frame (Z2, (see Fig. 8,) to which are connected the devices for locking the frame D4 in various positions when turned upon the vertical pivot (Z. These devices are shown in Figs. 8 and 9. A movable plate Eis set under the extension-frame (Z2, provided with the handle or finger-plate E', the upwardly-extending pin E2, and the downwardly-extending pin E2. A plate E4 is fixed to the frame Z2 and is interposed between the frame and the plate E and has a curved slot c, Fig. 9, drawn from the pivot (Z as a radius, and is also provided on its forward edge with a series of teeth or notches c' capable of engagement with the pin E2.
A spring e2 is attached to the frame (Z2 and is capable of slight movement to and from the same, and the pin E2 is normally held in engagement with the teeth c by the pressure of the spring c2. The plate E, being capable of slight lon gitudinal movement when pressed longitudinally in the direction of the arrow in Fig. 9, presses the spring c2 away from the plate E4, and the pin E2 is thereby released from the teeth d, whereupon the frame D4 may be swung about its pivot CZ to the extent permitted by the curved slot e. A pin CZ'- extends through the plate E and into the slot c IOO IIO
in the bar D2, which last runs in the guides D2. This pin, therefore, retains the sliding plate E stationary and forms the stop which, moving in the slot e, limits the movement of the frame D2l and retains the sliding plate E in a fixed position, while permitting the extended portion d2 of the frame to swing about the pivot d as a center. The downward-ex tending pin E3 of the plate E slides in a slot d0 in the bar D3. The bar DS is clamped to the guides D2 by a handle D7, which actuates a screw D0, engaging the bar D3 and clamping the guides D2 between the bar D3 and a washer D0.
The swinging back is provided with means for attaching the focusing plate, a plateholder, or a roll-holder for iilms. The supplementary frame D0 is provided with four pivoted levers F, (see Figs. l, 2, and 4,) two of these levers being on the lower side of the frame D0 and two being on the upper side thereof. Each lever F is pivoted near the middle of the frame D0 at f. The upper and lower levers on each side are connected together by means of the bent wires F', which are attached to the free ends of the levers and extend therefrom around the frame D0, (see Fig. 4,) being normally pressed by springs f', so that the springs tend to bring the levers into the position shown in Fig. 2. Each lever is slotted at the end, as at f2 f3, for engagement with pins f4 upon the upper and lower sides of the focusing-plate F2, Figs. l and 4, or upon the plate-holder or a roller-holder. The slots have ends open in the same direction, so that the pins f4 may enter the slots by movement in the same direction. The action of the springs F2 brings the focusing-plate, plateholder, or roller-holder closely against the back end of the supplementary frame D0. XVe thus provide means for attaching plate-holders or roller-holders of varying thicknesses to our camera.
In order to hold the levers F in a suitable position for the insertion of the focusing plate, plate-holder, or roller-holder, we provide a stationary guide-plate G, Fig. 4, upon the inside of the swinging back. In Fig. 4 it is shown attached to the inner side of the frame D4. The connecting-wire F slides over the plate G, and being somewhat elastic slips over the corner of the plate and engages it, as shown in Fig. 4, whereby the levers F, connected to that wire, are held away from thel frame D0, and in order to disengage the wire F from the plate G we provide a push-button g, which is normally pressed outward by a spring g. When the push-button g is pushed inward, it presses the wire F inward and away from engagement with the edge of the plate G, so that the action of the spring f immediately moves the levers F back to press the plate-holder or roller-holder against the frame D6 from the position shown in Fig. 4 to that shown in Fig. 2.
