PHOTOPLATE-HOLDER.

a I Specification of Letters Patent.

Patented March 5, 1907.

Application filed Augus 8, 1905. Serial No. 273,258.

To aZZ whom it may concern:

Be it known that I, JOHN R. citizen of the United States, residing at Readstown, in the county of Vernon, State of Wisconsin, have invented certain new and useful Improvements in PhotoplateHolders; 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.

This invention relates to cameras, and more particularly to plate-holders therefor, and has for its object to provide a holder arranged for the reception of supplemental holders of different sizes, the holder being adapted for easy and quick adjustment to receive the different supplemental holders.

Other objects and advantages will be apparent from the following specification, which describes an embodiment of the present invention.

In the drawings, forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a front elevation of the present holder with the slide removed and showing a supplemental holder in position. Fig. 2 is a section on line 2 2 of Fig. 1, the slide being in position. Fig. 3 is a longitudinal section through the slide and adjacent parts. Fig. 4 is a detail view of the slidegrip in perspective. Fig. 5 is a longitudinal section, the slide being partly withdrawn.

Referring now to the drawings, the present invention comprises a rectangular frame 5, having a back 6 and transversely-eXtending supporting-plates 7. Upon the forward face of each of these plates 7 there are pivoted a pair of plates 8, the outer end portions of which are rounded, as shown 'at 9, these rounded portions being directed toward each other and being provided with intermeshing gear-teeth 10, so that movement of one of the plates 8 upon its pivot results in similar movement of the other plate 8 of the same pair.

Strap-springs 11 are secured to the end pieces 12 of the frame 5 at one end and have their other ends engaged in notches 13 in the outer side edges 14 of the plates 8, the arrangement of these springs 11 being such that the plates are held with the outer ends of their areuate portions 9 in engagement with the end pieces 12 of the frame, the inner ends of the plates thus lying'at the limits of GARLICK, a their movements toward each other.

'lhe plates 8 carry arms 14 at their inner ends, which when the plates 8 are in their normal positions extend toward the center of the frame, though it will be understood that when these plates are moved against the action of the springs 11 the arms will be moved away from each other. Each of the arms carries a forwardly-extending pin 15 at its free end, these pins having heads 16, as shown, and it will be seen that these pins occupy the corners of a rectangle, so that a supplemental plate-holder 17 may be disposed in position for engagement by the pins, which will hold the plate-holder 17 at the center of the frame 5. It will also be apparent that the pins 15 may be separated or permitted to move toward each other to receive and hold plate-folders of different sizes.

The frame 5 is grooved, as shown at 18, for the reception of a slide 19 of peculiar con struction. These grooves 18 lie adjacent to the forward open side of the frame, and at one end of the frame the end piece 12 adjacent to the forward side thereof has an opening 22 thercthrough, with which the grooves 18 communicate and through which the slide 19 moves.

The slide 19 consists of a body portion 23, which is hollow and which is open at its inner end, as shown at 2 1, and at the outer end of the slide there are attached thereto guides 25. The body portion of the slide is composed of front and rear plates 26 and 27, respectively, which are held in spaced relation to each other by means of strips 28, secured between the plates at the edges thereof, these strips at their outer ends having rearwardl extending enlargements 30 and being curved at their outer ends, as shown at 29. The forward plate 26 of the slide is curved rearwardly around the curve d ends 29 of the strips and is secured to the rearward edges of the enlargements 30, so that the passage 24 between the plates has a return portion 31, extending toward the free end of the slide. The guides are secured to the extensions 30 and communicate at their outer ends with the return portion 31 of the passage for the reception of a curtain 32, movable upon a roller 33, journaled betwen the outer ends of the strips 28 and extending transversely of the slide. The guides 25 are slidably engaged in passages 341, formed in the end portion 12 of the frame, and when the slide is moved inwardly these guides slide into the holder.

The curtain 32 has at its inner end a grip 35, adapted for engagement with the slide 36 l of the supplemental plateholder 17, engaged by the pins 15, and it will be apparent that the curtain 32, having, as it does, a fingerpiece 38 at its outer end, may be grasped by this finger-piece to move the curtain into the I guides 25, thus bringing the grip 35 and a slide engaged thereby into the space between the plates 26 and 27 of the slide 19.

The grip 35 consists of two pivotally-connected jaws 38 and 39, respectively, and eX- l ten ding inwardly from the strips 28 at the innor ends of these strips there are pins 40, which are so disposed that they enter between flanges Y and Z at the ends of the jaws 38 and l 39 when the grip is moved inwardly with the curtain 32 to separate these jaws for the rel ception of the slide 36 therebetween, and l when the curtain is moved to move the grip outwardly a spring 41 brings the jaws together, they having moved out of engagement with the pins to grip the slide.

It will thus be seen that in use a plateholder may be disposed within the pins 15, the slide 36 of this plate-holder being in operative position and the slide 19 being withdrawn to expose the plate-holder. The frame 5 is then disposed in the camera, and the curtain is moved to open the grip 35. The slide is then moved to bring the jaws 38 and 39 into position to engage the slide 36, after which the curtain is moved to disengage the jaws from. the pins 40, which permits the jaws to engage the slide, when the slide may be withdrawn and picture may be taken. It will be understood that the jaws are disengaged from the pins before they are moved out of position to engage the finger-piece of the slide 36, so that they grip the latter.

It will be seen that the adjacent end 12 of the frame limits the movement of the outer end of the curtain, and the arrangement is such that this limitation prevents entire removal of the slide 36 from the plateholder, so that the slide may be returned to operative position by moving the finger-piece 38 of the curtain away from the frame.

It will be seen that the slide 19 may be moved inwardly to bring the grip 35 into position to engage the slide of the supplemental plate-holder, should this plate-holder be small, and it will also be apparent that this movement of the slide brings the outer end of the curtain nearer to the frame to reduce the possible movement of the curtain, thus preventing the withdrawal of the slide from the plateholder, as described above.

If the present device is to be used as a plate-holder, the plate being engaged within the pins 15, the slide 19 is used as is the usual plate-holder slide, as will be readily underl stood. l

What is claimed is 1. A plateholder comprising a frame, pairs of plates pivoted in the frame adjacent to the ends thereof, the plates of each pair being connected for simultaneous movement, said plates being disposed for engagement of their outer ends with the frame to limit the inward movement of their inner ends, means for holding the plates yieldably with their inner ends at the inward limits of their movement and pins carried by the inner ends of the plates, said pins being adapted for the reception of a supplemental plate-holder therebetween.

2.
