Absolute Control Clutch and Brake 



PATENTED 



This exclusive James feature makes possible the quick lowering of the tub by its own 

 weight, thus saving time in doing the chores — yet keeping the speed of descent under the 

 absolute control ol the operator. 



The Iriction brake enables the operator to lower the tub slowly — a sixteenth of an 

 inch, or the entire length ot the chain — or drop it quickly to within a few inches of the 

 floor, and stop it almost instantly. 



The empty tub can be dropped from an eight-foot track to the floor in fi\e seconds; 

 the "Big Boy," tilled, can be raised to an eightToot track in from 20 to 25 seconds. The 

 first time you have a chance, compare this record with other carriers, and then figure out 

 for yourself how much time this one leature will save you in a year. 



The Iriction brake and the clutch are both controlled by the one lever, hence both are 

 operated with the one hand. It is not necessary to touch the hand chain when lowering 

 the tub — the one hand and the one lever starts, controls and stops it. 



When ready to lower the tub, a quick, strong pull on the control lever will release the 

 clutch and set the friction brake; the pressure on the lever then controls. Release the 

 pressure somewhat and the tub begins to descend; a slight pull slackens the speed regard- 

 less of the weight in the tub; a stronger pull stops the descent. 



The lever may then be released entirely, setting the clutch instantly, holding the tub 

 firmly at that exact point; the clutch never slips. 



This clutch IS also a time saver when raising the tub, because it; prevents any slipping 

 back, a thing that is so annoying when raising a loaded tub with a hoist using dog and 

 ratchet. The James clutch takes hold so quickly and firmly that, no matter how heavy the 

 load, the James Carrier cannot slip back a fraction of an inch, even though it be raised an 

 inch at a time. 1 here is no lost motion. 



There are no ratchet teeth on the James Carrier, nothing to break or get out of order. 

 The X-ray picture on the opposite page shows the simplicity of the mechanism and how 

 it operates. In the picture the clutch is set. 



"Big Boy" Hoist 



Even a boy can operate the "Big Boy" carrier. The hoist is so geared as to make 

 possible raising a heavy load in the shortest time without undue effort. 



The chain and sprocket type of hoist is used, the chain being the same size as that used 

 to drive most grain binders. Every mechanic knows that this type of hoist has the least 

 friction, excepting only the direct hoist which, however, requires more power. 



The worm gear hoists so often used are extremely wasteful of power because of 

 a loss of power through friction; this may be verified by any textbook on the subject, 

 or by any engineer. The mere fact that with worm gear type of carriers the tub will 

 not lower of its own weight, but must be pulled down as well as up, shows how great 

 the friction must be in the worm gear hoist. When the brake and clutch on the James 

 Carrier are both released, the tub drops almost instantly, running free, proving how little 

 the friction is. 



The frame carrying the lower sprocket of (he "Big Boy" hoist is adjustable to take up 

 any slack in the chain, thus making it possible to overcome the effect of any wear in the 

 lifting apparatus. Hoist is constructed throughout of the best iron and steel. All bear- 

 ings are machined — not merely cored.
