Changing Bag for the Moving 

 Camera Operator 



THE traveling motion-picture camera 

 man must carry his tripod, tilting 

 and panoramic heads, camera, magazines, 

 cranks, masks, dissolvers, fade-outs, filters, 



Holes are cut in the side of the camera box 

 and cloth sleeves provided in the openings 



etc., and in addition to all this, a chang- 

 ing bag. With such an outfit, and often 

 more, he welcomes any scheme to lighten 

 or dispense with any portion of the 

 equipment. One cameraman, a moving 

 picture operator, is not bothered with a 

 changing bag since he has had his camera 

 case altered, as illustrated. 



The case is made light-proof and two 

 round holes are cut in the side of the box. 

 Into these holes are fastened sleeves of 

 heavy black light-proof cloth with elastic 

 bands sewed into the outer extremities. 

 This enables the operator to put both 

 magazines and films in the carrying case, 

 which is then closed and locked to prevent 

 accidental opening. He then inserts his 

 arms in the black sleeves, reaches into the 

 carrying case and changes the film with no 

 danger of its being fogged or light struck. 



When the box is in use as a carrying 

 case the cloth sleeves are tucked inside and 

 serve as a cushion or pad to protect one 

 side of the camera. The holes do not in- 

 terfere with the value of the case, or its 

 appearance, if it is properly made. 



This same general plan can be worked 

 out by anyone in connection with a view- 

 camera and its carrying case. The prac- 

 ticability, however, depends on the size and 

 shape of the case in relation to the size of 

 the plates used, and the ease with which 

 such a case can be made light-proof. In 



most instances of this kind a new case 

 would probably be desirable, if not absolutely 

 necessary. The plan is of little value to 

 anyone but the itinerant photographer. 



Covering an Automobile Torque- 

 Rod Support with Leather Boot 



IT IS necessary to keep all working parts 

 on an automobile covered as far as pos- 

 sible to prevent dirt from entering. One of 

 the parts which can be readily covered is 

 the front support of the torque-rod. The 

 torque-rod serves the purpose of relieving 

 the strain on both the rear axle and the 

 springs when the car is started ; consequent- 

 ly the ultimate result of a faulty torque-rod 

 is a break-down on either axle or springs. 

 Most of the torque-rod trouble may be 

 traced to the dust and grit entering the 

 working parts. 



The illustration shows the shape of a 

 boot for covering this part. It is in the 

 form of a tee, the vertical portion covering 

 the opening in the support-casing and the 

 horizontal part covering the end of the 

 torque-rod. In order to insure the correct 

 cutting of the pattern it is best to cut and 

 fit a paper one for a trial. The leather

should be of very 

 tough quality and 

 well soaked in oil a few hours before being 

 cut. A strong and thoroughly waxed 

 twine is used for making the stitches at the 

 joints. — Adolph Klein.
