James Speed Reducer The D . O. James Mfg. Co.. 1120 West Monroe St., Chicago. 111.» has a n nounced an improved vertical-type, heavy-duty, worm gear a^eeô reducer, made to allow for vertical driving with the drive shaft projecting at either t o p or bottom. The housing is of high-grade gray iron, of ample size, provided with a large oil-cooling and h e a t - r a d i a t i n g chamber. Timken bearings support both sides of the gear shaft. The worm shaft is mounted on double Timken bearings on one side and Norma Hoffman roller bearings on the other. This bearing arrangement i n s u r e s proper operation and the a b s o r p t i o n o f radial and end thrust loads, eliminates excessive heating, and reduces wear of both worm and gear. Gear s h a f t s are 0.40 carbon steel, carefully ground t o size, and made oversize t o withstand emergency strains and starting loads. Worms are made integral with worm shafts of S. A . E . J a m e s Speed Reducer chrome nickel steel, g e n erated, h e a t - t r e a t e d , ground, and fully relieved. Gears are made of high-grade phosphor bronze, the larger sizes being made of a bronze ring, shrunk on, and keyed to a cast-iron spider.

The D . O. James Mfg. Co., 1126 West Monroe St., Chicago, 111., h a s designed a combination automatic backstop and flexible coupling for use on elevators, conveyors, and process equipment drives, where there is a likelihood of reversal of travel when equipment is standing idle, when the motor has been shut off after a* day's run, or in case of motor failure. The unit, consists of a drum-shaped housing, on the back of which is integrally made one-half of a flexible coupling, which contains free flexing· live rubber bumpers, and in which are cemented bound brook oilless bushings. A one-half coupling fitted with hardened and ground steel pins which float inside of the graphite-impregnated bronze bushings, a ratchet plate, three pawls with studs, sprines. and fastening bolts, and a two-oiece cover plate complete the unit. There are no friction surfaces or wearing parts, and t h e unit requires no care, attention, or maintenance. The backstop is applied on the drive shaft between a speed reducer and motor. A flange, attached t o the speed-reducer housing, is cast integral with a ratchet. This ratchet operates within the drum housing, which in turn is connected to the motor shaft through a flexible rubber bumper-type coupling. On the inner face of the housing three pawls are secured by the médium of studs, which engage with the ratchet the moment the housing stops revolving. One flange of t h e flexible coupling is cast integral with the drum housing, lending compactness and strength. Centrifugal force keeps the pawls out of engagement with t h e ratchet during operation, but should anything happen t o the shaft or motor, or should the motor be shut off, the pawls engage with the ratchet through gravity and provide a complete brake against reversal of travel of the elevator or driven machine. The unit finds ideal application a s a brake against heavy loads on all driven machinery where there is danger from loads running backwards and causing damage.

Exhibit of Norblo Air Filter The Northern Blower Co., Cleveland, Ohio, exhibited at the All-Ohio Safety Congress a specially constructed model of the latest type of Norblo air filter.
Air-Cleaning Although the cleaning of air for hygienic or industrial purposes is still a comparatively new science, little known except t o a few engineers w h o have specialized in air-conditioning, development has been rapid during t h e past few years. Many industries are just awakening to the damage wrought by atmospheric dust and the possibilities of better production and more sanitary working conditions with the use of air filters. The Midwest Air Filters, Inc., Bradford, Pa., since 1922 has been developing centrifugal air filters and now ofTers a "sinuous type" filter medium, which is said to c u t down the cost of filtered air considerably and to make air-filtering more widely applicable in industry.
