CAMERA.
SPECIFICATION forming part of Letters Patent No. 619,792, dated February 21, 1899.
' Application filed August 3, 1897. Serial No. 646,883. (No model.)
To all whom it may concern.-
Be it known that I, EDWARD O. SoHAAF, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Cameras; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon,which form a part of this specification.
The objects of this invention are more particularly to enable photographs of the interior of the stomach or other organs of human or other animals to be taken with greater ease and convenience and with greater perfection of detail and truth to nature than heretofore, to enable physicians to prescribe for abnormal conditions found therein more intelligently and with better results, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.
The invention consists in the improved electrophotographic apparatus and in the arrangements and combinations of parts thereof, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.
Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the views, Figure 1 is a perspective view of the improved apparatus; and Fig. 2 is a longitudinal section showing the photographic portions of the same adapted to be introduced into the said stomach or other organs, as above referred to.
'be employed.
cuit to produce the desired light. In connection with said battery and magnets are arranged circuit-wires d d for the induced current, to which are applied a suitable circuitcloser e of any ordinary construction, adapted to effect a closure of the said current to produce the desired light. graphic apparatus the said wires are inclosed in a rubber tube f,whereby they are protected from engagement with the walls and tissues of the mouth, pharynx, esophagus, stomach, &c. At the end of the said rubber tube f I provide a metallic coupling-piece g, which is suitably socketed to receive and hold the said tube, and is provided with a block h, of in- Near the photo sulation, to receive the terminals of the wires cl. Said socketed coupling g is interiorly threaded to receive a threaded sleeve 11, which holds the glass globe or tube j by which the filament is inclosed. At the back end of said sleeve 1' is a second block Z to receive one terminal of the filament k at a point opposite the terminal of one of the wires d to efiect a contact when the parts are screwed together. The end of the other wire is connected to the other end of the filament through the metallic sleeve 9 or in any other suitable manner. Any other means of electrical connection to produce an incandescent filament capable of producing a photographic impression upon the sensitive plate or pellicle may be employed. The coupling-piece 9 also provides bearings and a glass tube m,which serves as an inclosing case for the lamp. At the op-' posite end of the said glass tube m is arranged a second couplingn, having asocket to receive said tube at and having a reduced threaded extension 0, to which is fastened a second flexible tube or piece go. At the forward end of said tube 19 is a coupling-piece 4", adapted to be firmly attached to the flexible piece p, the said coupling having a reduced portion 1', on which is secured the rear section r of the camera. The said rear section is made removable from the coupling-piece r, and a disk 3, of sensitized paper, celluloid, or other suitable pellicular matter, may be inserted and held in place against the flat seat portion of the said coupling-piece, the said disk being thus positively and securely held at right angles to the central longitudinal axis of the camera. Upon said back section 'r",of the camera is telescopically arranged a forward section 1, which is adjustable in its relation to the back section, so as to change the focus of the camera at will. lVithin the forward section r is arranged a lens-carrying section 4, in which is seated the lens 2i.v
The construction thus provided is adapted to be inserted in the channels, ducts, or tubes of the body and finally to be entered into the stomach or other organ without injury or inconvenience to the patient. When thus in place, the lamp-circuit is closed and the lamp lighted. After an exposure of seven or eight seconds is made the circuit is again broken,
although the said exposure may be varied at f willin accordance with the variations in the photographically-sensitive pellicle or other conditions.
The telescopic sections of the camera are impervious to Water at their joints, so the fluids of the stomach are prevented from gaining access to the sensitive pellicle or otherwise interfering with the photographic portions.
Inoperating I ordinarily fill the stomach with water or other transparent fluid to thoroughly distend the same or separate the walls thereof and thus bring them in a condition to be photographedf Preliminary to thus introducing the transparent fluids to the stomach'I of course cleanse out the stomach or remove therefrom any foreign substances by means of an ordinary stomach-tube. The apparatus is then introduced, and because of the flexible tube 0 the electric lamp may be turned to lie at an angle to the camera, so that the light-rays are directed against the tissues in front of the lens. The picture is then taken, as above indicated.
I may enlarge the picture first taken by any suitable photographic means to bring it to a scale more convenient for examination.
The pictures are taken and the plates developed in a dark room or closet in any ordinary manner.
Having thus described the invention, What I claim as new is 1. The combination with a flexible tube adapted to be inserted into the passages of the body and circuit-wires within said tube, of a transparent section inserted into the length of the tube by means of connectingpieces one of which has meansfor supporting an electric lamp, said lamp, lying in the transparent section, an exteriorly-threadedconnecting-piece at the end of the flexible tube, and a camera comprising telescopic sections, the rear one being screwed to said connecting-piece and supporting the sensitive plate and the forward section supporting the lens, the distance between the lamp and camera being sufficient to allow a bending of the flexible tube to bring the lamp into position to throw light in front of the camera, substantially as set forth.
2. The combination with the wires d, d, and flexible covering therefor, of a piece of transparent tubing connected to the end of said flexible covering, an electric lamp lying in said transparent tubing and in circuit with the wires d, d, a telescopic camera, and a flexible connection joining said camera to said transparent tubing and capable of bending to bring the camera into such position that the light from the lamp will fall on objects in front of the camera, substantially as set forth.
3. The combination of the connecting-piece 'r, and camera secured thereto, transparent inclosing tube m, having the coupling 71, at
its forward end, flexible connection 19, extending from connecting-piece r, to coupling n, and permitting a bending of the camera and transparent tube out of their normal position in one straight line with the other parts of the apparatus, coupling g, an electric lamp supported by said coupling g, and lying in the transparent tube 4%, circuit-wires d, d,
