DYNAMOMETER.
No.187,0-88. Patented Feb. 6, 18771 $6M JZAMW UNITED STATES A PATENT QFFIGE.
JESSE BLACKINTON, OF R OSOOE, ILLINOIS, ASSIGNOR TO WILLIAM M. RICHARDSON AND F. W. WARNER, OF SAME PLACE.
IMPROVEMENT IN DVNAMOMETERS.
Specification forming partof Letters Patent No. 187,088, dated February 6, 1877 application filed October 15, 1875.
dynam'ometers; andconsists in the employment of abent spring, to the lower ends of which the draft-connection is attached, and provided also at its lower ends with slots, through which pass a bar having one end rigidly secured to the spring, and the other end sliding in a slot in connection with a second notched bar, passing through a slot in the bent spring, the opposite end of the notched bar being pivotally connected with a pointer, which indicates, on a graduated arc, the draft force, as hereinafter more fully set forth.
In the accompanying drawings, A represents a spring preferably made of cast-steel of suitable length and stiffness, rounded at its upper end to form the loop H, by means of which it may be attached to the plowclevis, or other implement, the draft power of which is to be tested. a a are eyes in the opposite or front ends of the spring, which receive the links E E and ring F forming the draft-connection. B is a bar passing through slots b b, near the outer ends of the springs, one end being rigidly secured by a bolt, or otherwise to the spring, and the opposite end sliding in the slot b in the outer end of the spring. I is a bar notched at n, passing through the slot b, the notch engaging in the edge of the slot. To the opposite end of the bar I is pivoted the pointer D. G is an arm attached to the bar B, curved at its upper end, and carrying the indicator 0.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is'
1. A bent spring, A, in combination with the sliding bar B, notched bar I, pointer D, and indicator 0, substantially as and for the purpose set forth. 2. The bent spring A, provided with slots b b, in combination with the sliding bar B, notched bar I, and pointer D, substantially as and for the purpose set forth.
