MAGAZIN E-CAM ERA.

SPECIFICATION forming part of Letters Patent No. 472,442, dated April 5, 1892.

Application iiled December 29, 1890. Serial No. 376,153. (No model.)

To all whom, t may concern:

Be it known that I, ARNOLD LEPLATTE- NIER, of Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Magazine-Oamera, of which the following is a full, clear, and exact description.

The objects of this invention are to provide an improved magazine-camera which will afford means to retain a series of sensitized plates or hns in a safe condition, expose them one at a time, remove the photographed plate by gravity to a dark-chamber, move another plate of the series into focus registered correctly, and simultaneously indicate the serial number of the impressed plate or film.

To these ends my invention consists in the provision of a simple, compact, and inexpensive camera-box and parts within, which will retain in series securely separated a number of sensitized plates or iilms, and further be adapted by a rapid single movement of one part of the operating` mechanism of the instrument to remove a plate or ilm that has been exposed before the uncapped lens and simultaneouslymove another plate to take its place, the exposed but untixed negative being conveyed by gravity to a dark-box, where it is perfectly protected from light or contact with other objects.

My invention further consists in the construction and combination of parts as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a portion of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of the device closed. Fig. 2 is a plan in section taken on the line 2 2 in Fig. 3. Fig. 3 is a longitudinal section on the line 3 3 in Fig. 2. Fig. l is a transverse section of the preferred form of the plate-holder. Fig. 5 is a cross-section of a modilied form for constructing the plateholder. Fig. G is a plan in section of a portion of the plate-containing drawer, showing a friction -spring enlarged and in position thereon. Fig. 7 represents the plate-containing drawer detached and in perspective, concealed parts being indicated by dotted lines. Fig. S is a detached view in perspective of a bracket-shelf whereon the plates in series are supported before and while exposed to receive a photographic impression. Fig. 9 is a broken enlarged plan view of the inner or top surface of the lower wall of the camerabox, showing the actuating-gear for the sliding drawer which holds the sensitized and impressed plates. Fig. lO is a detached view of the thumb-piece used to manipulate the gear shown in the previous ligure, which piece and its supporting-plate are located on the lower side of the bottom wall of the camerabox; and Fig. il is a broken enlarged view of a portion of'the box side wall, showing the sight-hole for the plate-register and a recorded number exposed therein.

The outer casing or camera-box A is made in the usual elongated rectangular form, preferably of hard wood not liable to warp, dovetailed together to insure stability, and of a size proportioned to the dimensions of the plates to be contained in it.

lVithin the box A a rectangular exposurecase B is secured, which occupies the upper portion forwardly. Said case is of less dimensions, transversely considered, than the interior of the box it is placed within, and, being centered therein, affords two channels d of equal width, which extend to the lower wall b of the case, that terminates said case near the vertical center of the box A. A partitionwall c is erected across the forward portion of the exposure-case B, which extends throughout its transverse area, joining the sides and bottom of the same with the top wall of the box A.

Aligning apertures are formed ator near the center of the wall c and upper portion of the front wall of the box, or rather in a laterallyremovable sliding panel A of the box A, as at d d', which circular orifices are designed to accommodate the fieldlens O, which may be of any approved form. The finder D (shown partly in Fig. l) may also be of any preferred make. These features, which are necessary portions of the instrument as an entirety, are not part of this invention, and therefore need buta cursory mention.

The lower wall b of the exposure-case B is not extended to have contact with the panel A but terminates a short distance therefrom. A vertical diaphragm e, that is erected from the bottom wall A2 of the box A across said IOO box, joins the front edge of the wall b,.as at e in Fig. 3, thereby cutting off all light from the opening d in the panel A and producing a dark box or chamber B below the wall b when the rear side is closed, as will appear. The side walls a of the exposure-case B are terminated in vertical alignment w-ith the diaphragm e by lateral wings a2, formed thereon, which extend to join the side walls of the box A, as shown in Fig. 2, thus defining the forward extent of the channels a.

The height of the box A and width. considered internally, should be equal to the exterior height and width of the plate-containing drawer E, which must slide therein without looseness.

The drawerE constitutes one of the important features of the invention and is constructed as follows: A rectangular base-board g is provided, which is about'equal in length. to that of the sides ct of the exposure-case B, and in width is adapted to slide freely within the boxAand nearly touch its side walls. The height of the drawer sides g is such as will allow them to move in the box A without obstruction, closely fitting therein to avoid rattling. A front wall g2 is erected at the Jforward end of the base-board g, which is of a ,for removal by the provision of a sliding door height that will permit it to slide closely beneath the lower wall b of the exposure-case B, and, as shown in Fig. 2, the sides g of the drawer loosely fit within the channels ct, so

that the upper portion of the drawer slides a wall g3 is extended 'from the top edges of the side walls g', which it joins, downwardly one-half of the distance from said edges to the inner surface of the base-board g of the drawer, leaving a space below the end wall equal to its height, the lower edge of said end wall gs lying in the same horizontal plane with the top edge of the front wall g2. The opposite walls of the drawer are parallel,

respectively,thusproducing a rectangular structure. As shown in Figs. 2 and 7, the side walls g of the drawer E are oppositely grooved in series, said parallel grooves g4 extending from the upper edges to the baseboard g, thus affording slideways for the reception of the plate-holders F. (Shown in position in Figs. 2 and 3 and detached in Figs. 4 and 5.) The plate-holders are shown in two forms, which are essentially alike so far as their office is concerned, the dierence in the two styles represented in the detached views consisting in the minor details of construction, which in the preferred form shown in Fig. 4 is more simple, and consists in a plate of sheet metal or other material'of proper size, rectangular. in form, and folded on two side edges and the-bottom edge toaiford border-fianges, as at h, these flanges being adapted to receive a glass plate or other prepared material which is to be photographically impressed and embrace three edges of such a rectangular plate,leaving one face practically uncovered, the holder covering the otherside to completely exclude light, there being integral guide-fianges hformed on the side edges of the holder to engage the grooves of the drawer E. The holder shown in Fig. 5 has its guide-flanges h formed from detached strips, which are soldered or otherwise secured to the back plate of the holder, so as to receive glass plates or films which have been sensitized and are ready to receive impressions. p

There are friction-springs G preferably employed to give the drawer E an equal move- `ment in the box A when it is slid therein,

which springs are elastic plates suitably bent to give them a bowed projection. These are seated and secured in a rabbet-channel on the lower outer surface of one of the side lwalls g aligning with the lower edge of the same, whereby the yielding action of the springs assures a regular progressive movement of the drawer and compensates for any slight imperfections of construction that might cause the drawer to move unevenly.

The entire rear end of the box Ais adapted A3, which is furnished with tongues, as at 1',

,on each side edge that slide freely in grooves produced in the side walls of the box on their inner surfaces near the rear vertical edge,

said door being also formed to interlock with the top and bottom sides of the camera-box,

4as shown inFig. 3, so as to afford a finished exterior, the door being retained in place by a turn-button t or other means.

There are two spaced parallel vertical strips 7o secured upon the inner surface of the door A3 near the transverse center, these being designed to receive and retain in removably secured connection a bracket-shelf G ,which IOC) is another important portion of the invention.

Said shelf is shown in Fig. 8 to consist of a platform m, which is of a sufficient width proportional to the breadth of the drawer E to slide therein freely/,and as a support for the platform it is secured yupon the upper edge of a vertical rectangular piece fm', which is made to slide in the longitudinal groove 1h12, formedin the top face of the base-board `g of the drawer E, a vertical piece m3 being attached to the 4front edge of the support m and the platform m also, whereby the bracket- :shelf is essentially completed.- There are two parallel strips ofl metal m4 attached to the upper surface of the platform m of the bracket-shelf G, properly spaced to permit the plate-holders F to rest upon them and reduce friction when these holders are slid upon the platform, as will be further explained. The

.bracket-shelf G is removably attached to the door A3, as before mentioned, by the tongueplate la', which engages the rabbet edges of the strips k on the door when the latter is Zslid from above downwardlyin contact there- IIR with, thus making a iixture of the shelf G', there being` a hook k2 formed on the lower end of plate 7J to prevent any upward movement of the shelf by its abutment on the lower side of the drawer E.'

Upon the lower surface of the drawer E a rack I is attached, which is longitudinally extended from end to end of the drawer, as shown in Fig. 2 in dotted lines, an enlarged portion of said rack being also shown imposed loosely upon a portion of the lower wall of the box A in Fig. 9. rlhe rack I is placed at such a distance from one side edge of the drawer E that its ratchet-toothed edge will be properly located to be engaged bythe teeth of theratchet-wheel J, which is seated upon the bottom wall of the box A near its transverse center and pivoted thereon.

In a circular aperture formed in the bottom wall A2 of the box A a cupped and radiallyflanged plate n is seated, its iiange n being embedded in the lower surface of the wall A2 and secured to it by any suitable means, the top face of the cupped depression of the plate projecting within the aperture of the bottom wall sufficiently to lie level with the inner surface of said box-wall, as shown in Figs. 3 and il. Upon the top face of the cup-plate n a doul'ile-toothed gear-hub 0 is rotatably supported centrally by the engagement therewith of a screw-th read r, which projects through a perforation in the center of the cupped plate and also through an axial perforation of the same size in the hub, the teeth 0 of the latter being cut with a radial face on each, which lie in the same line with the center of the hub, as shown in Fig. 9, the other edges of the teeth having a curvature of equal degree, as shown at oin said ligure. At a proper point on the top face of the cup-platena pawl p is pivoted, as at p, to permit the concave edge of the pawl to lie in contact with the curved faces o2 of the teeth o and lock them from backlash, which contact is enforced by a platespring p2, which tangentially projects from the convex edge of the pawl and bears against the secured portion of the detent-spring r, which has its resilient portion extended toward the teeth of the ratchet-wheel J, so that its slightly-bent end portion r2 may lie in the space between the points of any two adjacent teeth of said wheel and by pressure of the spring retain the wheel from being moved except by the rotation of the gear-hub 0, the pawl p having a toe o8 formed on its free end, which engages either of the teeth o and prevents a movement of the gear-hub o in the wrong direction. There is a hinged thumbpiece s provided to rotatively move the gearhub 0, the screw-stud r being attached to the piece s, which latter is located in the cupped portion of the plate n and may be folded therein or be turned at a right angle to the bottom of the cup-plate and by a rotatable movement of the same actuate the gear-hub, which will move the ratchet-wheel J and project the drawer E forwardly. The peculiar cut of the rack I and the wheel J, in connection with the parts that move these pieces, prevents a retrograde movement of the drawer until the gear-hub o is removed from meshing contact with the ratchet-wheel, which is effected by turning the thumb-piece Sinto the position shown by dotted lines in Fig. l0, and when the parts are so adjusted the operator, by placing his fingers on the pull-plates u, may withdraw the drawer through the opening afforded by a removal of the door A3.

All interior portions of the box A, drawer E, and other parts of the device within are coated a dead-black color.

There is an aperture cut in the rear wall of the drawer E to permit an inspection of the interior, so as to ascertain if the plates are all dropped, and as a further means for such a purpose there is a scale-plate M secured on one side of the drawer along its upper edge, which scale is numerically graduated in regular order from l upwardly, the number of graduations being equal to the number of grooves g'l in the drawer, and it :'s important that the grad uations on the scale-plate M and spaces between the centers of the grooves g should be equal, and that the distance between the teeth on the ratchet-wheel J and rack I should correspond therewith, so that a halfrevolution of the thumb-piece s will move the drawer and expose one of the numbers on the scale-plate before the sight-hole N, as represented in Fig. 1.

The exterior finish of the box A maybe varied to suit the taste of the manufacturer, and to adapt it for portability a leather-strap handle O is secured to the top side of the box preferably in a manner which will allow itto be attened, and on the lower side of the box at a proper point there is a threaded socketplate P inserted and secured for the reception of the upper end of a tripod or other support for the box when in service.

In operation,the device being charged with sensitized plates, by filling the grooves g4 of the drawer E and raising the plate-holders so as to rest them all on the platform of the bracket-shelf G', the lens being properly focused on the object to be photographed and uncapped, the lst plate in the series will thus be exposed. lNhen the exposure is sufficient, a new view may be adjusted by a change of position of the box A, and a movement of the thumbpiece s will shove the drawer E forwardly, so as to allow the impressed plate to drop off of the platform ot the bracket-shelf down into.

the dark-chamber below, or a series of negatives of one object may be rapidly photographed by a simple manipulation of the thumb-piece .s in the manner stated.

Slight changes may be made in the form of some of the parts, while their essential features are retained and the spirit of the invention embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom. IIaving thus described my invention, what I IOO IIO

claim as new, and desire to secure by Letters Patent, is-
