OPERATING MECHANISM FOR wHIsTLns.

Specification of Letters Patent. Patented J 311.13, 1920.

Application filed April 9, 1919. Serial No. 288,697.

To all whom it may concern:

Be it known that I. DUANE P. FULLER, a citizen of the United States, residing at Carlisle, in the county of Grays Harbor and State of Washington, have invented certain new and useful Improvements in Operating Mechanism for Whistles, of which the following is a specification.

This invention relates to an improvement in an operating mechanism for whistles, whereby the whistle may be operated from a remote point with a certainty of control and operation substantially equal to that of a short whistle cord.

It is particularly desirable in some operations, as in logging, that means be provided to permit the remote workman to signal to the engineer of the stationary engine employed as to what action is desired. This is usually done by providing an ordinary type of whistle, or other manually operable alarm. on or adjacent the engine,-with the operating means thereof extending a considerable distance. It has heretofore been proposed to connect a whistle cord to a spring post. and also to connect the operating cord to said post. The pull on the operating cord is designed to move the upper end of the post to thereby actuate the whistle cord and thereby sound a whistle. This can be readily accomplished by the operating cord extending in line with the whistle cord. but even then the vibration of the post will materially interfere with, if not preclude.a series of whistle signals in rapid succession, as may be necessary. Furthermore unless the operating cord extends in a direct line with the whistle cord. as for example if it should extend at right angles thereto, the device described would be practically inoperative.

The present invention overcomes these objectio s by providing means to eliminate the vib ation of the post. and to permit the operating cord to extend in any direction, from, and with the respect to, the whistle cord.

Tn the drawings Figure 1 is a side elevation illustrating the invention. Fig. 2 is a side elevation of the upper en of the movable post.

Fig. 3 is a plan of the same.

Fig. 4 is a side elevation. and Fig. 5 a front elevation of the operating cord guidlng means. I

For-convenience and illustration the im- 'proved alarm is here shown as a whistle 2,

mounted upon an ordinary type of donkey or other engine 1, such illustration of course indicating any type of manually operable signal and any power plant.

Whistle 2 is of any usual or preferred type, here shown as a steam whistle, normally held closed in any appropriate manner and opened for alarm sounding purposes'in the operation of lever 3.

A post 10 is pivotally mounted at 11, on the engine base, or other support adjacent the engine. The upper end of the post 10 is provided with a casting having a pair of horizontally disposed spaced parallel guide rollers 5 notatively mounted in such casting.

A second post 13 .is rigidly mounted on the engine, base or other support, and is provided at the upper end with a bracket carrying vertically arranged spaced parallel guide rollers 9.

The whistle cord 4 is connected at one end to the whistle lever 3, passes over one of the rollers5 from above. and downwardly to a point in advance of the post 10. and terminally fixed at 6. The operating cord 8 is terminally wound about a drum as 7, mounted upon a support between the posts 10 and 13. The drum is provided with an operating handle whereby the cord 8 may be wound thereon when not required for use and may have an ordinary dog and ratchet to prevent unwinding of the drum after a suflicient le gth of cord 8 has been unwound from the drum to extend such cord to the point required. The cord 8 extends from the drum forwardly and over the remaining roller 5 from beneath. being then passed between the rollers 9, and led therefrom in any desired direction.

A pull on the cord 8. no matter in what direction it may exte d from the post 13. will move the up er end of the post 10 from the whistle. pulling upon lever 3 through the whistle cord 4 and soundin the whistle. Upon release of the pull on cord 8 the spring of the whistle returns the post 10 to normal position. through the whistle cord. the depending portion of such cord preventing any vibratory movement of such post. The whistle may be thus sounded in ouick succession b proper operation of theoord 8. substantiall the same as it the whistle cord was being directly operated.

What is claimed, is:-

1. Means for transmitting motion comprising a pivoted post, a cord fastened at one end and having a sliding cooperation with the post, the other end of the cord extending away from said post, and an operating 'cord having a fixed terminal and an operating terminal, said operating cord having sliding connection with the post between its terminals.

2. Means for transmitting motion comprising a pivoted post, a cord having a sliding cooperation with the post, one terminal of the cord being fixed and the other terminal extending from the post and an operating cord having a fixed terminal and an operating terminal, said operating cord having sliding connection With the post between its terminals, and a drum about which the operating cord may be Wound to serve as the fixed terminal of such cord.

In testimony whereof I afiix my signature.

DUANE P. FULLER.
