123, 124. One of the brackets 121 has adjustably journaled there- 'in the tension roller 125, by means of the threaded spindle 126 and jam nut 127 Bifurcated journal brackets 128, 129 extend from the supporting plate 66. A pin 133 is journaled in the bracket 128 and which supports the film receiving drum 134 having the clamping spring 135 and flanges 136. A clamping sleeve 138 having the disk 139 with the locking pin 140 is fastened to the pin 133. The locking pin 140 looks with an opening in one of the flanges 136. A worm wheel is loosely carried on the pin 133, and a pawl 146 is pinned to said wheel. A ratchet wheel 147 is fastened to the pin 133, and a spring 148 carried on.

the worm wheel 145 bears against the pawl 146.

An auxiliary-bracket 149 extends from the bracket 128 and an auxiliary bracket 150 extends from the supporting plate 66. A worm shaft with the worm 156 is journaled in the brackets 149 and 150. The worm 156 meshes with the worm wheel 145. An operating handle 158 extends from the worm shaft 155. A. pulley 160 is fastened to the pin 133. A pin 163 similar to 133 is journaled in the bracket 129. A feeding drum 164 with the clamping spring 165 and flanges 166'is carried on the pin 163. A splin'e 167 extending from the pin 163 engages a notch in one of the flanges 166. A handle 168 extends from one of the flanges 166. A pulley 170 is fastened to the pin 163 and a spring belt connects the

pulleys

160 and 170.

A sleeve with the

tubular portions

178 and 179 extends from the supporting plate 66. A tubular column 180 extends up from the plate 5.5, whichlatter is supported on the base plate 20. A supporting bar 181 with the curved bracket 182 is adjustably supported in the column 180 by means of the screw 183.

A supporting sleeve 185 is slidably carried in the sleeve 179. A rack 186 is carried on the sleeve 185. 'A bracket 187 is carried on the sleeve 179 and has journalm therein the spindle 188 carrying the pinion 189, which latter meshes with the rack 186. A knurled head 190 is carried on the spindle 188. A lens barrel is fastened in the supporting sleeve 185 and carries the objective lenses 196 and 197.

The film 93 has one end thereof fastened to the feeding drum 164 and is wound around the same. The said film is led from the said drum around the rollers 124 and from t'hence between the guide plates 72 and 75. I The film then is led between the film guides 100 and 101 and between the rollers- 123 and the roller 125 and from thence to the receiving drum 134.

To use the machine as a stereopticon the operator pulls the handle 99 and thereby theslide bar 88 is moved and the gripping finger 91engages the openings 92, one at a time and pulls the film 93 in the direction of the arrow A. The distance traveled by the film is controlled by the stroke of the finger 91 in the opening 65. \Vhen the said finger reaches the end of its stroke a picture on the film is in proper position for the axial center of the lenses of the machine. .The stroke of the slide bar 88 which carries the gripping finger 91 is a little longer than the length of the opening 65. When the slide bar 88 is moved to propel the film it travels the full length of the opening 65 and upon its return stroke, the finger 91 rides on the film 93 until it reaches the other end of the opening, it then rides on the plate 63 during the completion of the return stroke of the slide bar 88. Upon starting another forward stroke, the finger 91 again engages an opening in the film. Upon the return stroke of the slide 88 the finger 91 bears on the film 93 with only very slight pressure. When the film 93 is to be moved continu ously the slide bar 88 is located so that the gripping finger 91 will bear upon the supporting plate 63, a little beyond the edge of theopening 65 which in turn is adjacent to the axial center of the lenses of the machine. The annular frames 116 and-"119 at the same time will be axially in line with each other and in line with axis ofthe lenses of the machine. When the film 93 leaves the drum 164 the latter turns on its axis and thereby rotation is given to the pulley 170. The latter, by means ofthe spring belt 175, transmits rotation to" the pulley 160. The drum 134 turns with the pulley 160 and the film is taken upfpnthe drum 134. The pulley 160 is somewhat'smaller in diameter than the pulley 170- to 'maintain the requisite tensioniy -'on the film 93. The tension on the film can be adjusted by locating the tension roller 125' in different positions, by means of the spindle 126 and the jam nut 127. With thefmovements of the slide bar 88 motion is transmitted to the bands 114.- and 115 through the lug 117 and pin 95. The pin 95 is always looked in the opening of the lug 117. When a picture on the film 93 starts to leave its position from the axial center of the lenses, the annular frames 1'16 and 119 move in opposite direc- 11 tions from the axial center of the lenses to stop offthe light. The frames 116 and 119 with their openings constitute a shutter for the machine. When the handle 99 is moved in a direction opposite to the arrow A, the frames 116, 119 again approach each other and are located in the axial center of the the film. The slide bar 88 with its coacting elements remain stationary and the

bands

114, 115 also remain stationary with the annular frames 116 and 119 in alinement with each other andwith the optical axis of the l/JGIISGS of the apparatus.
