Description

UNITED STATES PATENT EEICE.
IMPROVEMENT IN MECHANICAL MOVEMENTS.
Specication forming part of Letters Patent No. 121,893, dated December 12, 1871.
To all whom it may concern:
Be it known that I, THoMAs H. PERcIvAL, of Harpers Ferry, in the county of Jefferson and State of West Virginia, have invented a newr and Improved Mechanical Movement; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing makin g a part of this specification, in Which- Figure 1 is a plan view of the mechanism With the top of the case removed. Fig. 2 is a longitudinal vertica-l section of the same, and Fig. 3 is a perspective view of the double lantern-wheel.
This invention consists in a device for rotating a shaft by means of a double lantern-Wheel working in connection with a double spur-gear fixed on a shaft, the arrangement being such that the lantern-Wheel also operates as a paWl and prevents any backward rotation of the spur-gear in either direction.
Referring to the drawing, a b are the parts of the double spur-gear, both of them Xed on the shaft c in such relative positions that the teeth of each part are opposite the interdental spaces of the other. d is a shaft placed parallel with the shaft c and bearing a double lantern-Wheel, e, each of the parts of which has two teeth, f, oppositely situated with respect to each other, the teeth of each part being arranged at right angles to those of the other part. The lanternwheel is so placed with reference to the spur- Wheel that the teeth j', when the shaft d is rotated, engage alternately with the parts a b and communicate a constant turning forward to the shaft c. But whenever there is a tendency in the shaft c to turn backward in either direction such tendency is counteracted by that part of the lantern-wheel whose teeth stand in a line tangential to the circumference of one of the parts of the spur-gear. The lantern-wheel is therefore always in a position to prevent the spur-gear from turning in the Wrong direction.
In this instance the mechanism is represented as arranged in a case, g, secured upon a Hoor, la, the shaft c bearing a drum, i, below the Hoor, and the shaft d bearing a hand-wheel, j, above the case. The device can be applied to railroad car-brakes, windlasses, rudders, &c.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination of a double spur-gear, a b, with a double lantern-Wheel, ef, as specified.
