Lubrication is secured by placing a store of oil, in the chambers F, of the segmental bearings B, from which it is fed, as wanted, through the apertures G, to the bearing surfaces of the spindle and bush. Lastly, the exclusion of dust and grit is secured by forming a chamber H, upon the top plate of the bush, with an annular cap which shuts down over it, and encloses the spindle, in which chamber is placed packing yarn or other suitable material to intercept all extraneous material of this character. The top plate is bolted down to the external portion of the bush, and the whole enclosed, as shown in Fig. 1. All experienced millers are aware that the attainment of the above objects by a simple device is a very desirable achievement. By the use of this improvement the adjustment can be readily and accurately made, and the wear of the spindle is reduced to a minimum. We can fit any size spindle from 3½ to 5 inches diameter, and have three sizes of bushes, 7½, 8½ and 9½ inches square. In ordering bushes, all that is necessary is to state the diameter of neck of spindle and size of eye in bed stone, and the proper size bush will be shipped. Satisfaction guaranteed. We have some half dozen different patterns of bushes ranging in price from $2 to $20--some having three and some four followers for wood or metal. Lighter Screws and Hand Wheels. [Illustration] These engravings illustrate the style of hand wheel and screw with cap and washer that we make and furnish with our combined husk mills, and when ordered we send them with the irons needed with mill stones. The figure on the right shows the hand wheel, screw cap and washer in position when ready for operation. The wrought iron screw is cut in a lathe and is what is termed a square thread. The wheel cap and washer are all turned and polished, making a good looking, durable fixture, as well as an accurate means of adjusting the stone. We sometimes make these of brass. Lighter Levers and Arched Step. [Illustration] This shows our pattern for arched bridge pot and lighter lever for geared mills or when an elevated step is wanted. The part holding the steel on which spindle rests, is contained in a central lifting chamber, which is turned to fit the body of the arch, like a piston, thus allowing a perfect perpendicular movement without any liability to vary from its true position; the heavy set-screw at the rear end of the lever is to admit of more adjustment; the lever can be moved around at most any required angle without interfering with any part of the step. We provide means (not shown in this cut) to tram the spindle by screws placed in the central lift part of the step, when desired. Mill Steps.
