CHARLES H. SHAV, OF NEV YORK, N. Y.

PANoRAMlo CAMERA.

SPECIFICATION forming part of Letters Patent No. 624,553, dated May 9, 1899.

Application filed December 16, 1893. Serial No. 699,431. A(Nornoclel.)

TovctZZ wiz/0m, it' may concern,.-

Beit known that I, CHARLES H. SHAW, a citizen of the United States, residing in the borough of Brooklyn', city and State of New York, have invented certain new and useful Improvements in Cameras, of which the following is a specification.

My invention relates to cameras, and more particularly to that class of cameras known as panoramic cameras.

I will describe a camera embodying my invention and then point out the -novel features in the claims.

In the accompanying drawings, Figure l is a horizontal sectional view of a camera embodying my invention. Fig. 2 is a vertical sectional view of the casing and showing a rear elevation of the camera parts. Fig. 3 is a vertical sectional View. Fig. 4 is a detail cross-sectional View of a lens-cylinder and a light-shaft. Fig. 5 is aperspective view ofthe camera.

Similar letters of reference refer to correspond ing parts in all of the figures. A

A represents a suitable casing for containing the several parts of the camera. its walls-as, for instance, the wall A-is detachable from the remainder of the casing, and it is to this wall that I connect two plates, between which plates several parts of the camera mechanism are located and held. This arrangement permits of the working parts of the camera being removed from the casing for examination and the substituting of one film for another.

B B represent the two plates that are connected to the wall A and which extend outwardly therefrom. These plates are detachably connected to protruding -parts a of the wall A. The parts a may be integral with the wall' A' or separate therefrom, in which case they are held by screws a. Between the two plates B B and at the sides thereof I locate walls Z9. These walls may be supported by standards b, to which they are secured,

and the standards may be held at their ends between the two plates. These standards also serve to support the plates B B and to space them apart. The purpose of these walls b is to exclude light from that part of the film not within the path of movement of a lightshaft that is employed in the camera.

One of C represents a cylinder placed vertically in an opening provided in the wall A. Itis preferably arranged to have a portion pro jecting beyond the outer surface of the wall A'. It is arranged to oscillate in the opening'on journals that are provided inthe ends of the cylinder. These journals may conveniently consist of circular plates o, that fit in the ends of the cylinder C. These plates may be carried by the plates B and B', being secured thereto by anydesired means-as, for example, by solder. The cylinder is provided with an opening c in that portion of its wall projecting` beyond the wall A, and dia metrically opposite this opening is a second opening, into which one end of the light-shaft c2 is secured. The light-shaft is preferably rectangular in cross-section and is adapted to move with the cylinder, and it is of such a length as to have its free end move in a plane that is parallel with and adjacent the Viilm or other sensitized surface used in the camera.

c3 represents a lens that is carried by a suits ableholder c4. The holder c4 is inserted in an opening provided in a wood or other block c5, that is held Within the cylinder C. The lens is placed in the line of the openings in the cylinder C, so as to project the light-rays through' the light-shaft onto the sensitized surface. When the cylinder C, carrying the lens, is oscillated with the lens exposed, the light-rays from the different parts of the View being photographed will be projected by the lens through the light-shaft onto successive portions of the film or plate in the camera as the light-shaft is moved in front thereof. The cylinder may be oscillated in one direction by means of a coiled spring c6,that is preferably located within the cylinder. One end of the spring is secured to a stationary part* as, for example, to a pin c7, carried by one of the plates c-while the other end of the spring may be secured to the cylinder. The cylinder and light-shaft may be moved in the other and opposite direction for the purpose of setting the lens and light-shaft by hand. When the cylinder is moved in this direction, the spring is placed under tension to move the cylinder and light-shaft in the first-mentioned direction-that is, in the direction to expose the film.

It is obvious that the speed of theloo s j l 624,553

lens-cylinder and light-shaft may be regulated by changing the tension of the spring. The joint made by the wall of the cylinder and the walls of the opening in the part A, in which the cylinder is placed, may be made light-proof in any convenient manner, as by felt om or metal, which would conform to the wall of the cylinder. Any desired means may be employed for holding the light-shaft and cylinder in set position and for releasing them from set position. l have shown in the drawings, the following` arrangement of parts for doing this. A lever D is pivoted to the upper plate B, so as to have one of its ends d in the path of lnovement of the light-shaft. As the light-shaft is moved to set position this end d will be made to engage with the light-shaft to hold it against the action of the spring c6. A flat spring d is preferably provided'for holding the end d inthe path of movement'of the light-shaft. The otherend d2 of the lever is so arranged as to be engaged by a button d3, carried by the casing A, which when depressed to engage the end d2 causes the end (l to move out of engagement with the light-shaft. A shutter cs may be provided in the cylinder to cover thelens when desired, a knob or projection o9 being provided for moving it over the lens after the film has been exposed and the cylinder and light-shaft are to be reset. This knob or projection may also be used to move the cylinder and light-shaft to set position.

E E' represent shutters which are provided for the end of the light-shaft. One of the shutters is provided for closing the end of the light-shaft when the camera is in set position, while the other shutter is for closing the endv of the light-shaft after it has been released from set position and it has moved in front of the film to expose it. Vith this arrangement of lthe shutters for the end of the light-shaft all light-rays from the lens are excluded from the camera while the lightshaft is at rest. These sh utters are operated automatically and preferably by the lightshaft coming into engagement with them. Each shutter may conveniently consist of an L-shaped piece of metal that is provided with a pivot e at each end, which pivots have a bearing in the plates B and B'. A spring e2 i is provided for each shutter for the purpose of holding it in such position as to be operated by the light-shaft. These springs are preferably flat ones, andA they are secured at one of their ends to the walls I). The operation of these shutters is as follows: Vhen the light-shaft and cylinder are moved to set position, the li ght-shaft en gages with one arm e3 of the shutter, against which the spring e2 bears, and moves it against the action of the spring so as to bring the other arm e4 of the shutter over the open end of the light-shaft to completely close it. Then the light-shaft is released to expose the iilm, the end of the light-shaft moves away from the arm e4 to vthrow the light-rays onto the film. As it moves in front of the film it comes into engagement with the arm e3 of the shutter E and moves this arm to cause the arm e4 of this shutter to completely close the end of the light-shaft, and thus prevent any more light-rays enteringthe interior of the camera. The shutter c3 is then moved over the lens and the cylinder and light-shaft reset for anotherexposure. Afterthecylinderandlightshaft have been reset the shutter o8 is moved from in front of the lens, thus having the camera ready for another exposure. It will be seen, therefore, that the purpose of lthe shutter cs is merely to cover the lens while the camera is being reset and also to protect the lens from dust, dac., when not in use.

A film is preferably used in the camera, and provision is made for inserting in the camera the spool, on which the film is generally wound, and unwinding the film from the spool as it is needed onto a second spool. F represents the spool carrying the film f, and F the spool onto which the film is wound. The spool F is provided with the usual ratchet and the pawl engaging therewith, and this spool is turned by the usual key f2, carried by the casing A.

The rollers F and F' are removably held in spring-pieces f3, that may be secured to the i plates B and B on the outside thereof' by riv- Q ets, which rivets are located at the middle of l the pieces. A of the casing, sothat the spools will be in These pieces are near the wall the position shown in the drawings. The film from the spool F is passed over a roller f, journaled in the plates B B', andpreferably against curved flanges f4, that are carried by the said plates, and over a roller f5 to the spool F'.

Guide-rods f7 may also be provided to prevent the film moving away from the flanges while being transferred from one spool to the other. The usual opening A3 and its colored covering A4 are provided in the casing A in order that the position of an unexposed part of the film may be gaged through the usual marks or signsprovided on the backing of the film.
