Description

E. GLENDILLEN. Dog-Power.
No. 220,603. Patented Oct. 14, 1879.

IMPROVEMENT lN DOG-POWERS.
Specification forming part of Letters Patent No. 220,603, dated October 14, 1879; application filed May 31, 1879.
reference marked thereon.
Figure l of the drawings is a representation of a side elevation of my dog-power. Fig. 2 is a detail view of the lever and bar by which the dasher-rod is connected to the power, and Fig. 3 is a detail view of the upper end of the 'dasher-rod.
This invention has relation to dog-powers, and consists in the improvements in the construction of the same hereinafter fully described and particularly pointed out in the claim.
A represents belts or chains of suitable form and tensile strength, which pass aroundthe pulleys B and (J. D are round pieces of wood properly attached to these belts or chains by screws or bolts, in such a manner that they will be in contact on their adjacent sides, and by thus impinging against each other hold the endless-belt structure in a slightly convex position in that part intended for the tread of the animal at the point designated by the letter E.
His a bar attached to the lever K by the slot k and between the rollers of the dasher K. The dasher is provided with the anti-friction rollers 70 which work upon the upper and lower sides of the reduced portion of theleverK.
M is a brake which is applied to the flywheel and retained in any desired position by the button m, which works lightly and has the notch m, in which the handle of the brakelever rests, and which serves to retain the brake-lever at any part of the sweep of the button.
By my invention I avoid all friction which has attended the former construction, as the tread is self-supporting, having no bearings between the end rollers.
I do not wish to confine myself to round pieces, as flat square-edged pieces, slightly chamfered to receive the animals feet, would clearly do as well, and be no departure from my invention.
Also, by means of the bar H, I provide for a vertical upward and downward motion for the dasher, and avoid the horizontal motion attending the common form of attaching dash ers and similar devices to a working -lever or walking-beam.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a dog-power for a churn, the lever K, pro vided with the pivot k, in combination with the bar H, pitman l, and dasher K, provided with the anti-friction rollers W, as and for the purposes substantially as set forth.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
ELIJAH GLENDILLEN.
