' I. F. HDYT.
Shipper-Levers. N0.'149,l29, PatentedMarch 31,1874.
UNITED STATES ISAAC F. HOYT, GLENVILLE, CONNECTICUT, ASSIGNOR TO HIMSELF AND- J. R. BILLING, OF SAME PLACE.
IMPROVEMENT IN SHIPPER-LEVERS.
Specitication forming part of Letters Patent No. 149,129, dated March 31, 1874; application filed March 7, 1874.
To all whom it may concern:
Be it known that I, ISAAC F. HOYT, of Glenville, inthe county of Fairfield and State of Connecticut, have invented a new and Improved Shipper-Lever, of which the following is a specication:
My invention consists of the handle portion ofthe lever jointed to the main portion, and provided with a curved extension beyond the joint in a slot in the other portion, which raises the spring-catch out of the notches of the quadrant-bar, when the handle, after being taken in hand by the operator, is turned into line with the principal part of the lever for handling it.
Figure l is partly a plan view and partly a horizontal section of my improved shipperlever, and Fig. 2 is a side elevation.
Similar letters of vreference indicate corresponding parts.
A is the principal portion of the shipperlever. B is the handle portion; C, the springcatch, and D the notched quadrant-bar for holding the lever by the spring-catch. The handle portion B of the lever is pivoted to the end of part A, in a slot, E, and has a curved projection, F, extending a short distance along said slot under the end of the spring C, which is attached to the side of the part A of the lever, and at its end bends into the slot a little.
The spring presses on the point F, and throws handle B a little out of line With part A, when it is free to press the bit C into the notches. When the shipper is to be moved, the handle is turned into line with part A, and thereby it disconnects the spring-catch from the bar D.
This is a cheaper and simpler arrangement than the ordinary catch and trip-lever attachment to shipper-levers.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The handle portion B of a shipper-lever, constructed and jointed to the portion A, in combination with the spring-catch C, substantially as speciiied.
ISAAC F. HOYT.
