DOG-POWER MACHINE.

- SPECIFICATION forming part of Letters Patent No. 233,420, dated October 19, 1880.

Application filed August 16, 1880. (No model.)

for the purpose of driving a churn. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a vertical section through the Fig. 2 is a top view of the machine with a part of the tread-wheel broken out, showing the operation of parts underneath.

Similar letters refer to corresponding parts throughout both figures.

The sill A and the posts 0 and D form the main frame, and together with cross-sill d and posts 6 andf constitute the whole frame-work of the machine.

g is an adjustable bar, with a lever, h, for adjusting the pitch or slope of tread-wheel B, the shaft of which passes down through lugs on the bar g, and about which the tread-wheel rotates.

The lever his secured in place by a pin, r, passing through it into post 0, a number of holes being provided in the same for adjusting the lever in different positions.

The tread-wheel B is constructed with two cross bars or arms, '5, halved together at the center.

The rim j of the tread-wheel is formed of the bent-wood fellies of vehicle-wheels, (wagon, buggy, or sulky fellies,) to which the ends of arms i are secured.

The diagonal pieces are notched into under side of arms 2, and the treadway is formed by nailing on the outer rim and the diagonal pieces tapered slats radiating outward from center of wheel.

A railing is formed around inner edge of treadway by the standards I, with a ring or hoop, m, passing around through holes near their upper ends. This railing is for the purpose of compelling the animal to walk out near the edge of wheel B.

The rim of tread-wheel B is made to rotate the roller and fly-wheel N n by friction produced by the weight of the animal on the treadwheel.

Through the roller and fiy-wheel N n a shaft, E, passes, having its bearings in the posts 6 and f. 0n the inner end of this shaft is a crank, 0. To the wrist or pin of this crank one end of the pitmanp is attached, the other end working in a slot with a pin in the lower end of hanger a, the hanger a and workingarm I) being framed together at c, and secured in the angle with a brace, s.

The working-arm b is pivoted on a pin, t, secured to post 0, the other end having a slot and pin for attaching the churn-dasher to.

It will be seen the bearings of arm I), hanger a, and pitman p are in the same vertical plane with each other and parallel to the side of main frame of machine, thus bringing the principal strains of the working parts of machine on the strongest part of the frame.

Through the slot in the lower end of the hanger a are a number of holes for adjusting the pitman p, in order to give the churndasher a shorter or longer stroke, as may be desired. The numbers in connection with these holes are intended to indicate the number of gallons of milk which (the churn being of a given dimension, and the pitman in a given hole) it would be suitable to churn.

I am aware that horse or dog powers have been made or described having an adjustable rotary tread-wheel. I therefore do not claim such as my invention; but

What I do claim, and desire to secure by Letters Patent, is

1. The arrangement of crank O on the inner end of the shaft E, the wrist or pin of which is brought in the same vertical plane with the working-bearings of the arm I) and the hanger a, and in combination with the side of main frame of the machine, substantially as described.

2. The hanger 0, provided at the extremity with perforations and a graduated scale, substantially as described, for the purpose set forth.

DAVID I. KUHN.
