Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed February 28, 1913. Serial N 0. 751,387.

To all whom it may concern:

Be it known that I, FREDERICK SonwAN- imussnn, a citizen of the United States, and a resident of Jersey City, New Jersey, have invented a new and useful Improvement in Stereomotographs, of which the following is a specification.

My invention relates to stereopticon devices and particularly to that class of machines wherein the plates or things to be projected by the stereopticon are mechanically and automatically presented and removed therefrom.

The invention may be contained in a great variety of constructions. For the purpose of showing that a construction embodying the invention is operative, I shall illustrate one of such constructions and 1 shall hereinafter fully describe the same.

The invention consists, in the main, in providing a movable holder, support or container for plates, sheets or objects, images of which are to be projected and which will move in the vicinity of the lenses of the stereopticon, that is, in the vicinity of the position of exposure.

It also consists in a means for automatically. inserting the plates, sheets or other objects in the path of the projecting rays of the stcreopticon.

It also consists in means for removing the plates, sheets or other objects from the line of the projective rays.

It also consists in providing an intercontmlhng mechanism whereby a series of plates sheets or objects may be successively and intermittently presented and removed from the stcreopticon.

It also consists in providing a means whereby a plurality of plates, sheets or objects may be projected in rotation.

llifl'ercnt views of the particular construction selected for illustrative purposes are shown in the figures on the drawings forming a part hereof.

. Figure l, is a view of one side of the construction showing the container therefor in section. Fig. 2, is a plan view of the cons'truction. Fig. 3, is another side View. Fig.

4, illustrates some of the details for operating the slide used in connection with the particular construct-ion shown. Fig. 5, is a plate holder partly in section.

1, Fig. 1 is a container or cover for closing the parts embodying the invention. It is ported in any other thus be easily placed on the base 2'wh'ich supports the elements containing the invention. The base may be supported by legs 3. It may be supsuitable way. A proecting tube 4, containing projecting lenses is adjuslably supported on an adjustable pedestal 5 which is also adjustably sup ported on a standard 6. The standard 6 is secured to the base 2. A condensing lens 7 is also adjustably supported on the pedestal 8 which is in turn secured to the base 2. A Nernst glower 9 or other light giving body is supported in line with the lenses which are used for projecting images of objects when inserted in position of exposure. The glower and its regulating parts are contained in a'tube or cylinder 10. The cylinder is supported on a pedestal 11.

A means is provided for conventionally assembling a plurality of objects in order that they may be easily manipulated and brought consecutively in position for presentation to the rays of light of the stereoplicon. In the particular construction here selected the holder consists of a circular plate 20 which supports the views of the stereopticon. The plate 20, is composed of two parts, an annular plate 21 and a smaller circular concentric plate 22. The parts are secured together by means of the spokes 23. The annular plate is provided with a groove 24; and a plurality of radial recesses 25. Frames 26 shown in Fig. 5, in perspective are supported in the recesses 25 and in the groove Each frame 26 consists of a solid strip 27 made or bent in the form of a U. To the legs of the U are secured clips or channels 28 in which are inserted the stere 'opticon plates 29. The legs of the U-shaped strip arc of unequal length and one leg 30 is provided with an enlarged portion 31. There is inserted in the portion 31, a pin 32 which forms a pivot pin about which the plate frame may be turned. The pivot pins of the frames 26 are inserted in the channel 24 when the frame is placed in position on the annular plate 21. Springs 33 are inountw ed on the annular plate 21 and are located on opposite sides of each plate frame 26. The springs press upon the ends of the pins 32 and hold them in the channel 24. The plates and theirsupporting frames may inserted in position by merely pressing the pivot pins 32 underneath the upturned lips of the free ends of the springs and standard 48 located on the base 2.

. Fig. 1.

33. By the pressure of the springs 33 upon the pins 32 the plate frames are held in position in the radial recesses 25 in the plate 21.

The shorter leg of the U-shaped strip or plate supporting base 27 rests upon a circular pad or cushion 40 which is located on the disk or inner plate 22. Also a strip of leather or other elastic or flexible material 1.1 i supported on an inverted U-shaped piece 4-2. The-leather a1 is stretched across the free ends of the legs of the U. The Llshaped piece 42 is supported on an adjustable pedestal 47 which is supported in a cushion pad 40 and the elastic strip 41 form cushions for the plates as they are swung back and forth about the pivot pins 3:2. A spring so is also secured to the center of the U-shaped piece 42 and serves the double function of breaking the fall of the plate 29 and also holding the plate 29 in the plate frame and in alinement with the projecting rays of the stereopticon.

The plate frames are located radially upon the support 20. The support 20 is mechanically shifted intermittently so as to bring the frames and their-plates successively in the vicinity of the projecting lenses of the stereopticon by means of a motor 60. The motor is connected by a belt6l to a reducing gear box (32. This may be accomplished by the use of worm gears or by any suitable mechanism well known in the arts. The motor actuates a pinion G3 and gear wheel Get. A vertical rod is supported on the gear wheel 64. The rod 65 is provided with a lip 66. Lugs 67 are located upon thev plate 20 and are operated step by step by the lip '66 which engages with the lugs 67 upon the comple tion of each rotation of the gear wheel 64:. The lugs (37 ride over a bellied spring 68 which is adaptcd'to hold the plate 20 in the position to which it is moved by the operation of the lip (36. The spring 68 is supported 0 a pedestal 69 and a base 70. As the lugs (57 alternate with they plate frames in their positions around the circumference of the plate 20, the plate frames are moved successively intd alinement with the position of exposure of the stcreopticon.

As each plate comes in line with the position of exposure it is tripped over by a mechanism which is also n'ieclianicallv operated by the motor 60. The post 65 supported on the gear wheel G-l operates a lever which is pivoted to the standard 81 located on the base 9.. This is best shown in The lever 80 operates a link 82 which is connected to a bell crank 83. The free end of the link 82 is provided with a lip 84:. The lip 84 is adapted to engage with appendages 85 located on the frames 27 when t we link is operated. The lip 66 located I the post 65 first moves the base Theplate 20 into position and then the p'ost 65 engages the lever 80 which operates the link 82 and pulls the lip 8 1 against one of the appendages 85 which causes a plate frame to turn about its pivot pin 32 and drop upon the elastic cushion 41 and in position of exposure.

A means is provided for operating a shutter mechanism for cutting off the'light when the plates are moved. This is accomplished by the gear wheel 64 which is provided with a lug or facial cam ywhich operates upon the arm 91. The arm 91 is supported on the shaft or rod 92 which is rotatable in bearings 93. The rod 92 is also provided with an arm 94. The arm 94 is connected to a link 95. The free end of the link is connected to a gravity actuated shutter mechanism 96 of the type well known in the art. The link pushes the shutter mechanism and causes the shutter to close. When the cam surface or lug 90 located on the under side of the cog wheel 64: passes the arm 91, the pressure on the link 95 is relieved and the shutter mechanism opens and exposes the plate which has been dropped into alinement with the axes of the lenses. When the cog wheel 64 completes its rotation, the lug or cam surface 90 operates upon the arm 91 and closes the shutter mechanism 96. The lip 66 then engages with one of the lugs 67 and the supporting base plate 20 is rotated another step. The stereopticon plate which has been dropped into position of exposure, is swung a short distance upon the move ment of the base plate 20 and is slid off from the leather strip 11 which forms a smooth nonrcsistant substantially antifric tional surface and permits free movement of the plate about theaxis of the base plate 20 and also forms a reliable cushion for cushioning the fall of the plate when it is dropped into position of exposure. As the plate is moved from the leather strip 41, it passes over and onto the lug or pin 100. The pin 100 is supported on the free arm of the bell crank lever 83. Upon further rotation of the cog-wheel 64 the post 65 engages the lever 80 and operates the bell crank lever 83 whereupon the lip 84 not only engages with the appendage 85 of the succeeding plate frame but also the lug 100 which receives the plate that was dropped during the preceding operation'is raised. upward until the plate falls into posltlon and the short leg of the frame drops upon the mat 40 located on the inner disk 22.

Upon continued'rotation of the gear 84, the shutter mechanism relieved and the shutters are opened and another plate is the post 103 which forms a pivot post about which the base plate 20 may be rotated. A stop 10% having a set screw 105 may be secured to the post 103 for holding the plate 20 in position. The supporting base 20 together with the stereopticon plates may be removed as one piece and may be replaced by merely dropping the base plate onto the stop 104. If desired an adjustable thimble may also be secured to the plate 20, which may be placed over the post 103.
