DAVID EMORY PANGBURN,.OF UTIOA, NEW YORK.
IMPROVEMENT IN DOG-POWERS.
Specification forming part of Letters Patent No. 154,075, dated August 11, 1874; application filed July 2 0, 1872.
exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 is a side elevation embodying my improvement. Fig. 2 is a side elevation of the same.
This invention has relation to dog-powers; and the novelty consists in the tread-wheel, made in two parts, and hinged together to form a perfect wheel.
In the annexed drawings, A represents a frame, which is firmly connectedtogether by means of cross-bars and brace-rods. M N represent the posts and guard-rails attached to one side of this frame to prevent the animal that drives the wheel from stepping off while operating the machine. K represents the horizontal bar, upon which the journalboxes J are attached in the usual way, to support and hold the shaft B in its relative position. To this shaft B the crank-wheel I is keyed, at its outer end, as shown in Fig. 2. This crank-wheel, with its shaft, is arranged on a parallel line with the tread-wheel, as will be hereinafter described. 0 D represent the horizontal dividing-arms, the length of the wheel, less the width of the dividing-band. G G are the frame-arms, extending from the periphery to the center of the wheel, and secured to their respective half-wheels by means of screws, or bolts, and metal plates. On the upper surface of these arms G G is laid the animal-track or foot-boards H H. F F represent arms, rigidly secured to the upper side of one of the sectional wheels, and to that section that is designed to be folded, and connected to the arms 0 G by means of hinges 3 3, so that by putting the sections of the wheel together and arranging them in the same plane a complete circle is formed for use. The lower ends 0 of the arms F F are intended to come 'up to a level with their opposite ends, and are prevented from passing beyond, and too far, by metal stop-plates secured to the arms G. To the under side of thefoot-boards, and to the outer ends of the frame-arms Gr, is secured a circumferential band, E, which is designed to come in contact with, and to rest upon, the crank-pulley I. This band is to be of a corresponding width to the pulley. L represents the spindIebracket, pivoted near its upper end to the upper end of the inner support of the frame A. This spindle-bracket consists of three journal-bearings, a a a with a notched ratchet-lever attached thereto. The vertical shaft 6 of the tread-wheel passes down through the journal-bearing a and c and is stepped into the lower bearing 0. The adjustable notched ratchet'bar m is pivoted to the lower end of the bracket L, between the bearings 01. and a and works in conjunction with the stop 0, attached to diagonal brace O of the frame A, as fully shown in Fig. 1. By this means the desired angle is given to the tread-wheel.
The manner of operating my machine is as follows: After the wheel is properly set and in position, the spindle-bracket is set to the desired angle to secure such motion and power as may be required; the wheel is driven by the movement and weight of the animal, and if the wheel runs too slow or too fast a change can readily be effected by moving the ratchetbar m either up or down, as may be required, without stopping the machine. To the crankwheel a pitman can be attached in the ordinary manuer for the purpose required.
It will be seen from the above description that I am able to adjust the tread-wheel without stopping the animal-by adjusting the notched lever working in conjunction with the stop on the diagonal bar. Also, I am able, by constructing the wheel in two sections, to fold it in a compact small form for storing away and transportation.
I claim as my invention- The sectional hingedtread-wheel, consist-
