MAGAZINE PLATE-HOLDER FOR CAMERAS.

Specification of Letters Patent. Patented July 6, 1909.

Application filed April 15, 1908. Seriai No. 427,113.

illustrated a suitable embodiment of my invention without special regard to correct proportions, certain parts being shown relatively large and exaggeration being generally indulged in for purposes of clarity.

The device comprises a relatively flat rectangular box 1- equipped substantially midway between its ends with a partition wall 2- of less width. than the depth of said box to provide slots 3 and 4 bordering said. partition wall on either side. Adjacent one side wall 5 of said box is a longitudinally disposed partition wall 6 which is cut away on opposite sides and at respectively opposite end portions to provide longitudinal slots -7 am. -8 establishing communication between the plate comartments -9 and -10- relatively and the compartment -1 1 in which the plate transferring mechanism is disposed. Said slots 7 and 3- are disposed adjacent the front and rear walls of the box 1-, said front wall plate 12 being provided with the exposure opening 13- controlled by the slide -14 movable in guide grooves in the side walls of the box in the customary manner. The rear wall '15 of the box is preferably hinged to afford convenience of access to the compartment -10 for the insertion ofplates. Each of the plates -16 is disposed in a plate holder 17 preferably of sheet metal, said plate holders eonforming in construction as closely as possible with the plate holders generally employed as far as the means for maintaining the plates in proper position are concerned. and each receiving only one plate instead of two. Said plate holders are equipped at opposite ends with inclined ton ues 18 disposed substantially paralleI with each other, said tongues being adapted to serve as deflecting means or wedges whereby choking of the device is obviated as will hereinafter appear. The plate holders -17- contained 1n the lower compartment -9- are passed forward by To all whom it may concern:

Be it known that I, EDWARD L. C. MORSE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Magazine Plate-Holders for Cameras; and I do hereb r declare the following to be a full, clear, and exact descri tion of the invention, such as will enabIe others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel constructiori in a magazine plate holder for cameras, the object being to provide a device of this character which will admit of the insertion and consecutive exposure of a relatively large number of plates and which is simple, easily operated, durable and efficient, and consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings illustrating my invention: Figure -1 is a vertical section of plate holder constructed-in accordance with my invention on the line 11 of Fig. -4. Fig. -2- is a plan section of the same on the line 2-2 of Fig. -1. Fig. 3 is a vertical section on the line of Fig. 1. Fig. -4 is a vertical section on the line 44 of Fig. 1. Fig. 5 is a longitudinal section of a small plate holder employed. Fig. -6- is a fragmentary front elevation of the small plate holder. Fig. 7- is a fragmentary detail perspec tive view of a guide employed. Fig. -8- is a fragmentary detail vertical section of the small plate holder.

The main object of my invention is to provide a magazine plate holder of maximum capacity in roportion to its size and which is very simp e and easily operated.

Similarly to other magazine plate holders my device is equipped with two compartments from each of which plates are transferred to the other by externally actuated means, the main feature of novelty embodied in my invention residing in the construction whereby exposed plates are consecutively transferred from one compartment to the other and are replaced consecutively by unexposed plates transferred from the last named compartment to the first named, each compartment primarily receiving an equal number of plates.

In the accompanying a flat spring 19- secured to the rear wall 1 5 and which preferably bears upon the middle of the rear wall of the last named plate holders, thus maintaining the foremost plate in position to be exposed when said slide 14 is raiser. It is, of course, essenti( 1 that the device be so constructed that the plate to be exposed shall register with the normal position of the ground or focusing drawings I have glass in the usual manner, but I have made no attempt to of accomplishing this end. The opening -13 is of less width than the plate holders -l7. The box 1 is also provided with a supporting plate disposed parallel with and above the bottom wall thereof, upon which the plate-holders 17 are supported and. is likewise provided with a plate 21 disposed parallel with and below the top wall, said plates being termed, for purposes of convenience, false bottom and false top respectively and serving to enable the plate shifting device to be moved to engage the plates to transfer the same. The foremost plate holder 17 in the compartment ---10- is borne upon at its side edge portions by flat springs -23- thus maintaining all of said plate holders and plates at the rearward limit of movement in said compartment. In the drawings the depth of the box is greatly exaggerated, showing too much free space. In practice the free space should not exceed in depth the space occupied by two plate holders l7-.

The plate shifting or transferring device consists of the plunger '-24tlongitudinally movable in a guide 25- secured to the outer wall of the compartment l1-, said. plunger being capable of being rocked to a limited extent in said guide. Said plunger projects through the upper wall of said box *1 and is equipped with a knob -26- for convenience. At its lower end and midway between its ends respectively said plunger is provided with oppositely disposed arms 2T/ and -28- each equipped at its free end with a projection 29 adapted to pass through the slots 7 and 8- respectively, said arms being so disposed that when said projection 29- of one thereof projects through one of said slots, the other thereof is withdrawn from the other slot.

Secured to the front and rear walls of the box 1 midway between the side wall -5- and partition wall -6- thereof and at respectively opposi e ends of the compartment -11 are guide strips 30 and --31 terminating at one end flush with the upper and lower faces of the partition wall 2- respectively and terminating at their other ends flush with the false top and bottom of the box l--. Said guide strips are so disposed as to prevent rocking movement of the plunger except when the latter reaches the upper and lower limits of its movement respectively thereby serving to prevent either projection 29 of the arms 27 and -28 from passing out of engagement with a plate holder 17 after the latter has been started from. either compartment into the other. In order to prevent retrograde movement of said plunger until. a plate shall have been moved the entire distance necessary to effect its transfer from one compartment to the other said guide strips are properly illustrate the manner I equipped with yielding ratchet projections 32 relatively oppositely disposed and extending toward said partition wall 6- to engage the free end portions of said arms -27--- and 28 as the projection -29- thereof respectively engages a plate holder 17 to transfer the same.

My device is operated as follows: The )lates are primarily inserted in the plate holders 17- and the latter are then divided into two stacks of equal number and inserted face downward into the compart-- ments -9- and 10-, the rear wall constituting a door being swung open for this purpose. After inserting the plate and closing and locking said rear wall or door (for which purpose the latch 33- is pro vided) the device is ready for use.

The box -1 is inserted in the camera in the same manner as an. ordinary plate holder and after exposing the foremost plate in the compartment-9- the plunger -2-il is rocked to throw the projection -29 of the arm -27 into operative position and said plunger is then pulled upwardly thereby causing the plate holder -17 containing the exposed plate to pass through the slot -3 into the upper compartment --10 where it is forced by the springs against the foremost plate holder contained therein. The said plunger cannot be lowered nor rocked until the movement necessary to fully effect transfer has been completed, thus preventing the operator from only partly transferring a plate and thus upon the next succeeding exposure spreading his picture partially over two plates. After having thus transferred the exposed plate to the compartment lO the operator rocks the plunger to throw the projection 29- of the arm 28- into operative position relatively to the rearmost plate in said compartment 10 and by then returning said plunger to its primary position said plate is transferred to the compartment 9. These operations are repeated after each exposure until all plates have been exposed, it being obvious that thus each compartment always contains the same number of plates and that the possibility of error in operation is entirely obviated.

No part of the operating mechanism can come into contact with the sensitized surfaces of the plates to scratch and mar the same and each. plate is isolated from the other so that the light cannot penetrate more than one of salne at a time.

The means whereby the plate shifting device is maintained in engagement with the plate holder and is prevented from being reversed until transfer is fully effected constitutes the most essential feature of the invention. The said projections or tongues l8 of the plate holders 17 serve to force a plate holder which may accidentally V reciprocally movable 1n guides in said receptacle, and oppositely (l1S posed projections on said plunger adapted when the latter is turned to be respectively thrown into and out of engaging relation to the plates in the respective compartments, as and for the purpose specified.
