Above, focussing straight 

 down. As shown at the 

 right, each foot-member of 

 the tripod is attached to a 

 sleeve, the inner end of w'hich 

 is a swinging cam bearing 

 upon a spring attached to 

 the tripod leg. The spring 

 has a felt pad which locks the 

 tripod members together by 

 friction, the lever system 

 (shown closed and open)

supporting arm the camera automat -

 the lever remains rigidh' in that [)o- 

 sition. Without requiring an\' ])re\'ious 

 adjustment or setting, as is the case 

 with the cameras generally used, it can 

 .be quickly adapted to any kind of 

 panoramic view to be taken. A horizon- 

 tal panoramic adjustment may be readih' 

 changed to a \-ertical adjustment and 

 \icc versa, while by manipulating the 

 finger-piece the direction of rotation 

 anil the speed at which such rotation 

 takes place may be ada[>ted to i)re\ail- 

 ing conditions in a quick and reliable 

 manner. 



The camera can be mounted in the 

 twinkling of an eye for rapid picture- 

 taking. It can be trained in any 

 direction as accurately and as quickly 

 as a cowboy can draw a gun. If a tripod 

 is not at hand a window-sill, a rock, a 

 saddle-horn, a tree-branch, a knee — in 

 fact, an>-thing stationary may serve as 

 a base for operations. 



Where ciiiick action is absolutely 

 imperative, the newspaper photographer 

 can film every stage of an exciting fire 

 rescue, or a riot, or a sinking ship, or 

 an explosion, or a shooting, or, indeed, 

 anything heretofore solely within the 

 compass of the hand or still camera. 



The lens adjustments, instead of being 

 in front, are in the rear, so that focussing 

 through a diaphragm according to light 

 conditions may be carried on while the 

 picture is being taken. By means of 

 an ingenious eye-piece the actual image 

 on the film maybe obser\^ed 

 during the process of ex- 

 posure. To appreciate the 

 importance of this, it may 

 be said that it never has 

 been accomplished before 

 in either still or motion 

 cameras. The eye - piece 

 remains closed until the eye 

 is pressed against a light- 

 proof, black velvet rim; the 

 actual image being record- 

 ed on the negative is seen. 

 It is impossible to turn 

 the camera so rapidly in 

 any direction that a blur 

 is produced. The range 

 of tilting and "panoram- 

 ing"permits the operator to 

 turn his lens straight up or straight 

 down beneath the camera itself. This 

 enables the operator to photograph an 

 ant hill or nest one moment and a 

 Zeppelin the next. .Ml friction danger 

 is eliminated so that the film can not be 

 scratched while taking pictures. The 

 camera complete weighs thirty pounds; 

 the old-style apparatus weighs from fifty 

 to sevent>'-five poimds. 



The film-containing box has verj'^ 

 little in common with the boxes now 

 used. The camera may lie run at the 

 standard speetl of sixteen pictures a 

 second, or the speed may be doubled 

 or trebled, as desired.
