CO., OF SAME PLAGE.
IMPROVBD 'BREAD-POWER.
The Schedule referred to in these Letters Patent and making part of the same..
To all whom it may concern:
Be it known that I, Josurn II. D ULL, of Mansfield, in the county of Richland and State of Ohio,'have in- Yrented certain new and useful Improvements in Tread- Powers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, and to the letters of reference marked thereon, likelettcrs indicating like parts wherever they occur. l
'lo enable others skilled in the art to construct and use my invention, I will proceed to describe it.
My invention relates to tread-powers, and
The invention consists in a novel construction and arrangement of the gearing, and also in a device for taking up the slack in the endless belt, thus compensating for the wear in the same. A
Figure l is a perspective view of the tread-power complete;
Figure 2 is a transverse vertical section ofthe same, through the center ofthe gearing; and
Figures 3, 4, 5, and (i, are views of portions, shown in detail.
In constructing my improved tread-power, I provide a frame, A, of the usual style, with an endless belt, U, mounted therein, as is customaryin this class of machines.
At the front end of the machine I locate a transverseshaft, B, having secured rigidly to it two sprocket-wheels, D, as represented in tig. .l.
'lhe form of these wheels is shown clearly'in tig. 5, they being provided with sprockets or projections, '11, veach having a notch, l, in its outer end, into which the joint-rods (t of the endless belt C lit, these sprockcts being located at distances from each other exactly equal to the distances apart of the rods of.
This shaft B, with its wheels D, is so located that the endless belt, at 'the front end of the machine, will bear upon and pass around the wheels D, so that, as the belt O'is moved, it will impart motion to the wheels D, and'theiebyto the shaft B. Y v
Upon this shaft B, just outside of the frame, I secure a cross-bar, F, which `is madc strong and rigid on the shaft, this bar thus forming two radial arms, as shown in iig. 2.
Each of the arms, near its outer end, has a journal, o, projecting from its outer face; and on each of these journals I mount loosely a spur-wheel, I, these latter gearing into an internallygeared or toothed circular rack, E, which is bolted firmly to the side of the frame A, so as to be fixed and stationary.
Upon the outer end of the shaft B I then mount loosely a band-wheel or pulley, L, this wheel il having its hub made to project inwardly between thc wheels I, there being a pinion, H, formed on or attached to this inner cud of the hub, into which the wheels I gear, as shown in ligs. l and 2.
By this construction and arrangement of parts it follows that, as the belt C is moved, the shaft B, with its arm F and the wheels I, are made to revolve; and the latter, by gearingr into the circular fixed rack E, are made to rotate ou their journals o, and they, in turn, impari'. motion tothe pinion H, which, being fast to the baud-wheel L, causes it to rotate also, the direction in which the various parts move being indicated by the arrows in fig. 1.
The belt C is`monutcd on small wheels er rollers, n, secured to the ends of the joint-rods a, and these rollers travel on a rail at each side ofthe frame, both above and below, as is usual in this class of machines.
At the rear end of the machine I provide a segmental or curved iron rail, T, of the form shown in iig. 6, for the wheels a to run on, this curved rail being formed with slotted anges, tand my, by which it is bolted fast to the frame, in such a manner as to form ya continuation ofthe track from the upper to the lower rail, as shown in iig. l.
By means of these slots, which may be made either in the part I or in the frame to which it is attached, the pieces 'l may be adjusted, to compensate for any wear in the joints of the belt C, and keep it at'the proper tension. v
By this method of constructing and arranging the various parts ofthe machine, I am enabled to produce a very eiiicieut and complete tread-power, adapted to all the purposes and uses for'which such machines are. used.
By the use of the planet-wheels I, and the circular raclcE, the shaft B and the pinion H are relieved of the radial thrust or pressure, and, consequently', of the friction which exists with ordinary spur-gearing where the wheels have a bearing on one side only, and thus the power is applied to a better' advantage, and more efiieiently utilized.
Having thus described my invention,
. Xilhnt I claim isyl. A tread-power, having two or more planet-wheels, I, secured to its driving-shaft, and arranged to operate substantially as described.
2. The combination ofthe shaft 1S with the planettrack T, arranged to
