Application led September 21, 1914, Serial No. 862,801. Renewed March 2, 1920. Serial No. 362,743.
a plate holder into vwhich said plates arey charged and which holds them in the camera during exposure.
These devices are all made light-proof and are so adapted vto each other that the plates may be passed from one to the other in daylight so that the complete operation of Ytaking a plate from the container into the plate holder, and exposing it in the camera, may all be performed `in daylight and without actual handling of the plate.
The invention may be best understood by describing a specific form of it and illustrating the same with drawings wlthout attempting to makev a general description, 1t being understood, of course, that such drawings and descriptions are illustrative merely, andthe invention is not to be limited thereto, except as recited in the claims at the end hereof. v
In the accompanying drawings p have illustrated in perspective the various lnstruinentalities which go to make up the invention. i
In the drawings;
Figure l is a sectionalV view showing a plate container with a series of plates therein and with a closing slide withdrawn tol more perfectly show the. interior arrangement thereof. y* v Y Fig. 2 is a sectional view of the lower part yof the container.
Fig. 3 is a longitudinal sectional view of a plate holder adapted for use with the container shown in the two previous figures.
Fig. 4 is a view of a similar plate holder with one of the covers partly withdrawn to show the sensitive plate therein. i
VFig-7.5 isa partial view, partly in section,
showing a plate holder inverted to give a view of the lower end of the same. 0 Fig. 6 is a view showing the discharge f. end of a container and showing a modified form of valve for closing the same or opening it to discharge a plate, and
Fig. 7 is a longitudinal sectional view of a plate container similar to the one illustrated in Figs. l and 2, but showing a modified arrangement thereof.
'In these figures, and referring first to Figs. 1 and 2, which show the dry plate container, l represents the outer frame of the device which is in the form of a box with its sides closed in by the side-pieces, 2. The upper part of the box has an opening l5 through which plates may be inserted, which is closed by a slide, 3, moving in grooves 4L. The inside of the box is divided into two chambers by a skeleton partition 5, and the dry plates 6, are packed in these chambers, one set facing one way and one the other, so that a plate holder may receive a plate from each chamber and have it in the proper position for exposure in the camera.
The plates, when in the container, run upon a ledge at 7 of the solid end, l, and their upper ends are held away from the center of the container by such skeleton flange or piece as 8.r
lIn the solid end of the container at each side of the partition, 5, are grooves, 9, each of which contain a false bottom, l0, pushed up by a spring 11. Eachof these false bottoms has side pieces, l2, extending up into a circular notch, 13, in the edge of the boxv and open to the outside so that the operator can, with his fingers, depress these sidepieces, l2, thus forcing `the false bottoni down against the action of the spring, 1l. When the false bottoni i0, is thus depressed the container may be tilted and the innermost of the plates, 6, will slide over onto the false bottoni. then be further kdepressed and a further tilting of the container cause the upper edge of the plate to pass under the piece, 8, to the center of the box, at which time the false bottom is released and pushed up by the spring, raising a plate upon the inner side of the pieces, 8, when it is in position to be discharged into the plate holder as hereinafter described. This operation is repeated with the other side of the container to get the second plate into position for discharge into the plate holder. One of these plates 6,
is shown in Figs. l, 2 and 7 in such posi- The false bottom may tion. In the upper part of the container, at the ends of the opening, 15, lwhich is closed by the slide, 3, there is a notch, 16, at each end of the opening. This notch receives a projecting flange, 17, shown in Figs. 3 and 5, upon a plat'e holder and serves to register the latter with the container for the reception of a charge of plates.
It will be readily seen that the above described container can also be used for carrying away the sensitive plates after being exposed.
The plate holder shown in Figs. 3, 11, and 5 may be of any usual form except as now described. The usual plate holder consists of the form, 18, divided by a central partition, 19, into two chambers which are closed by the slides, 20, operated by the hand pieces, 21. To adapt this plate holder for an element of my invention I construct the flange, 17, as already described, to register with notches, 16, in the plate container and I make the end of the plate holder adjacent to the flange, 17, and opposite to the hand pieces, 21, open and close the opening with the slide 22. lVhen it is desired to charge the plate holder, the same is applied to the container by placing its end against the open end of the container and inverting these two devices so that the container is above and the plate holder below, and withdrawing the slides, 3 and 22, so that the two plates in the container which are in position for discharge will drop out therefrom into the plate holder. The slides, 3 and 22, are then closed again and the plate holder may be removed from the container and placed in the camera and the plates exposed in the usual manner. For convenience, the slide, 22, may have a piece of: string, a3, as shown in Fig. 4L, attached to it by which it may be pulled out instead of having a projecting portion to take hold of. Also the sliding covers, 20, may be marked differently upon the two sides, or the hand pieces, 21, may be differently colored upon the two sides as a reminder of whether the respective plate has been exposed or not.
Instead of the slides, 8, 22, etc., which constitute valves for closing the open ends of the several boxes to which they pertain, I may make use of a rotating valve, as shown in Fig. 6, which comprises a cylinder, 39, having a longitudinal slot, l0, through it, such that when the cylinder is rotated on its axis to the position shown in the figure just mentioned, the open end of the box is closed thereby and when it is rotated 90 degrees from that position so that the slot, 40, registers with the opening in the end of the box the plates may beV entered or removed therethrough.
These various instrumentalities are provided with felt, velvet or other flexible means, 41, as shown in Fig. 3 only, for
making the registering parts, slides, etc., light-proof.
The modification shown in Fig. 7 relates particularly to the false bottoms 10 shown in Figs. 1 and 2 and consist in providing the same with a projecting side Z), the object of which isto keep the remaining plates in position upon the ledge 7 of the solid end 1 while discharging one oi the plates G from the container and further relates to the sides of' the container which I provide with the slides 20 shown in Figs. 3, and el, instead of' the side-pieces 2 shown in Figs. 1 and 2 so that the plates can be inserted in the frame through the sides thereof, if desired by removing the slides 2O which are operated and arranged in the manner above described.
Having thus described my invention, and an embodiment of it, in the full, clear and exact terms required by law, and knowing that it comprises novel, useful and valuable improvements in the art to which it pertains, I here state that I do not wish to be limited to the precise construction and arrangement of the several parts, as herein set forth, as the' same may be variously modified by a skilled mechanic without departing from the spirit of the invention.
That I claim and desire to secure by Letters Patent of the United States, is the following, to-wit:
1. A photographic plate holder comprising a container for dry plates having a discharge opening at one end and means for closing the same and provided interiorly with holding flanges and a false bottom whereby the plates may, by gravity, be released from said flanges and brought into position for discharge.
2. A photographic plate holder comprising a container for dry plates having a dischargeopening at one end and means for closing the same provided interiorly with holding flanges and a false bottom whereby the plates may, by gravity, be released from said flanges and brought into position for discharge and spring means for holding said bottom in position.
3. A photographic plate holder comprising a container for dry plates, having a discharge opening at one end and means for closing the same and provided interiorly with holding flanges and a false bottom whereby the plates may., by gravity, be released from said flanges and brought into position for discharge and means for operating said false bottom.
et. A photographic plate holder comprising aframe having removable covers on the sides thereof, a plate chamber between said covers and a central top opening for inserting the plates in said chamber and means to support the plates within said chamber and to remove the same therefrom, and means to close said opening.
5. A photographic plate holder compris- I have hereto set my hand, in the presing 2L frame having e Sliding cover on each ence of tWo Witnesses, the 31st day of Auside thereof, a central partition between said gust, 1914. covers forming two lateral plate chambers, YOSHIMORI YAMADA.
5 and rotating means to hold the plates therein Vtnesses:
and remove the same therefrom. T. OKAWARA,
