JOSEPH .STEGER, OF NEW YOR-K,N. Y.
Letters Patent No. 88,990, dated April 13, 1869.
IMPROVED METHOD OF TRANSMITTING MOTION IN CAR-BRAKES AND OTHER MA- CHINERY.
The Schedule referred to in these Letters Patent and making part of the name- To all whom it may concern Be it known that I, JosEPH STEGER, of the city, county, and State of New York, have invented a new and useful Improvement in Transmitting Motion, for Oar-Brakes and other Machinery; and I do hereby declare the followingto be a full, clear, and exact de scription thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which drawing- Figure 1 represents a longitudinal vertical section of this invention.
Figure 2 is a plan or top view of the same.
Similar letters indicate corresponding parts.
This invention relates to a device or mechanism by means of which the rotary motion of one shaft can be transmitted to another shaft, at the will of the operator, and independent of the direction in which the moving shaft revolves.
This invention consists in the arrangement of two roller-j aws, which are hinged together, and one of which extends across one side of the moving shaft, and carries one roller, while the other jaw extends across the opposite side of said shaft, and carries one or more rollers, and also the shaft or drum to which the motion is to be transmitted, said shaft or drum being geared together with the'last-named roller or rollers, in combination with a Windlass, lever-cam, or other mechanism capable of closing up the roller-jaws against the periphery of the moving shaft, in such a manner that,
when the jaws are closed, said moving shaft is firmly clamped between the rollers in the jaws, and the shaft or drum to be moved is caused to revolve with more or less velocity,'according to the proportion between the gear-wheels connecting said shaft or drum with the roller or rollers in the second jaw; and, by releasing the roller-jaws, the motion of the shaft or drum ceases.
In the drawing- The letter A represents a shaft or axle, from which motion is'to be transmitted to the shaft or drum B.
This shaft or drum has its hearings in 'a lever, G,
which has its fulcrum in a pivot, a, and which forms one of my roller-jaws, being armed with two rollers,'b
b, which connect with the shaft or drum B, by pinions c o, and a cog-wheel, d, as shown in the drawing.
The second jaw, D, is connected to the jaw G, by
a pivot, e; and this jaw carries a roller, j; which is situated on the side of the shaft A, opposite to the rollers b b, in the jaw O.
From the loose end of the jaw 1.) extends a rope or chain, g, over a roller, 71, in the end of the jawG, and thence to a Windlass, B, so that, by turning this windlass, the two jaws are closed, and the rollers b b are brought to bear on opposite sides of the shaft A.
By these means, the shaft A is firmly clamped between the roller-jaws, and its motion is transmitted to the rollers bl) without fail, since theshaft, even if it should be uneven, or run out of truth, will, at all times, and in every position, remain clamped between the roller-jaws, which is not the case if the rollers are brought to bear on the shaft only from one side, or if the bearing-point of the rope or chain, drawing the rollers up against the shaft, is rigid, and unable to accommodate itself to any unevenness or untruth in the shaft.
A spring, I, acting on the jaw 0, serves to open the jaw as soon as the strain on the rope or chain 9 ceases.
The mechanism for closing up the roller-jaws may, however, be changed in many different ways; for instance, a lever or cam may be substituted for the windlass; and I do not wish to confine myself, in this respect, to the precise 'arrangement shown.
It must also be remarked that only one roller might be placedinto the jaw 0; but, by. having two rollers, as shown, a more powerful motion is imparted to the drum B.
If the shaft A revolve in the direction of arrow 1, fig. 1, and the roller-jaws O D are caused to close, the roller 1) revolves in the direction of arrow 2, and the roller 1) in the direction of arrow 3; and both these motions are transmitted to the drum B by the pinions c c and gear-wheel d, causing said drum to revolve in the direction of arrow 4.
The speed with which the drum revolves can be increased or diminished, by changing the proportions between the pinions c c and cog-wheel (l,- and it will be readily seen that a very powerful motion can be imparted to said drum, enabling the same to resist a strain of a very great force.
If the motion of the shaft A is reversed, the motion of the drum B-is also reversed; but, otherwise, the effect of my device will be the same, in whatever direction the shaft A revolves.
In the drawing, I have represented my device for transmitting motion as, applied to the axle of a railroad-car; and, in this case, I intend to run a rope or chain from the drum B to the brake-levers, so that, when the drum B is caused to revolve, by closing the roller-jaws, said rope or chain will wind up thereon, and the brakes will be applied. v
If desired, the same device can be applied to one of the axles of the tender in a train of cars, and the rope, connected to the drum B, can be made to extend throughout the entire train, and made to act upon the roller-jaws, or other devices, under the several cars, so that the'engineer is enabled to apply the brakes on the entire train.
My device for transmitting motion may, however, be applied with advantage to a hoisting-apparatus, or to any other mechanism where it is desirable to transmit a rotary motion from a moving shaft or axle to another shaft or drum, at the will of the operator.
Having thus described my invention,
What I claim as new, and desire to secure by Letrollers in one of the jaws being made to actuate a ters Patent, isshaft or drum, B, substantially in the 'mannerherein The arrangement of two hinged jaws, G D, each shown and described. earryingone'or more rollers, which, when the jaws are JOSEPH STEGER. closed, bear on the shaft A from opposite sides, and Witnesses: are capable of accommodating themselves to any e'e- W. HAUFF, centricity or unevenness in said shaft, the roller or O. WAHLERS.
