Not illustrated. 1861 edition. Excerpt: ...arranged, this pressure has been made to act upon the journals, thus causing much loss of power and the rapid wearing away of the journals and their boxes. To obviate this objection, and also to attain to a much greater economy of space necessary for the gearing used, is the purpose of my present invention. In the accompanying drawings, fig. 1 is a side elevation of the contrivance used by me for this purpose. Fig. 2 is a section of the same along the line x y z. Fig. 3 is the same section, showing a difference of form. Fig. 4 is still another variation of the same contrivance. Fig. 5 shows a plan of the contrivance as applied to a blower. For this purpose I construct a driving wheel A, having a strong rim or flange a. Two intermediate pinions b and c, having their tread upon the internal surface of this rim, communicate their motion to the centre pinion d, as shown by the arrows attached to those wheels respectively. This centre pinion will, therefore, move with a rotary speed accelerated over that of the driving wheel in an inverse ratio to the length of their respective diameters. DimpfeVs Improved Friction Gearing for Machinery. The intermediate pinions b c have stud journals, which work in elongated bearings or slots, as shown at /. The journals of the centre pinion work also in slots g, the centre line of each of which bisects the angle x y z. The weight of this centre pinion and of the shaft or other machinery which is supported by it, will generally be sufficient to produce all the pressure upon the intermediate pinions b and c, which will be found necessary. When it is desirable to increase the friction, a spring may be used, as shown at h. The angle x y z being very obtuse, gives to the centre pinion the power of a wedge, and...
