HENRY O. MUSTARD, OF WEST POINT, INDIANA.

AUTOMATIC DEVICE FOR OPERATINGVWHISVTLES.

SPECIFICATIN formigpart of Letters Patel lt No. 592,015, dated'october 19, 1897.

Application filed June' 29. 1397.

To all whom 't may conccrm V Be it known that I, HENRY C. MUSTARD, a citizen of the United States, i'esidingat WVest Point, in the county of Tippecanoe and State of Indiana, have invented'certain new and useful Improvements in Automatic Devices i for Operating Whistles, of which thefollowtinue to sound until purposely disengaged by the fireman or engineer, thus insuring that a warning shall be given as long before the locomotive passes such a point as may be deemed proper, and also nsuring a continuous sound as long as may be desired.

An apparatus enbodying my said invention, as applied to locomotive-engines, will be first fully described and the novel features thereof then pointed out in the claim.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters and numerals of reference indicate similar parts, Figure 1 is a side elevation of a loeomotive provided with apparatus embodying my said invention Fig. 2, a detail View, on a considerably enlarged scale, illustrating the Construction more clearly, as seen from the dotted line 2 2 in Fig. 3; Fig. 3, a transverse sectional View showing another View of said apparatus, and Fig. 4 a detail diagrammatic View illustratin g an alternative Construction.

In said drawings. the portions marked A represent the locomotive; B, the railwaytrack; C, a strike located alongside said track; D, a bar or'lever mounted on the locomotive and adapted to be operated bysaid strike;

E, the whistle, and F the rod for Operating said whistle.

The locomotive, track, whistle, and rod for Operating the same of course are or may be of any usual or desired Construction, and, not being peculiar'to my present invention, will not be further described herein, except incidentally in descrbing said invention.

The strike C is of a suitable form to oper- Serial No. 642305. (N model.)

ate the bar or lever D. In order that itshall have a yielding character, so that the jar of the contact shall not be too'violent, I prefer to make it of two parts, the upper or main part being supported on springs s uponthe lower part, which in turn is secured upon the ties'T, as best shown in Fig; 2. The said upper part is preferablyslotted, and the slots pass over pins c upon the sides of the lower part, which sides are inclosed by the edges of the upper part. The pins and slots connect the two parts together, while permitting a vertical movement of the upper part upon the lower part, as will be readily understood.

The bar or lever D is shown in the princi- .pal views as pivoted at d to the side of the fire-boX of the engine. It may be m ounted in any desired manner which will enable it to operate the whistle when properly moved. It has a foot or fioat D which comes in contact with the strike O. This foot or fioat is so connected to the lever proper as to be adjustable in relation thereto, so that exactly' the desired amount of contact between said foot or fioat and the strike O can be secured.

The leverD is returned to position after the strike has been passed by a spring D attached thereto and to some suitable point on the locomotive. There is shown running from the top of this bar or lever a link 1, connected to a lever 2, whose other end is connected to a rod 3, which in turn is connected to a lever 4:, which is connected, through a link or chain 5, to the whistle-actuating rod F. A detent 4: on the same shaft or pivot with the lever 4: is adapted to engage with a catch 6, and said catch is normally held forward by a spring 11. The bell-crank lever is pivoted at 7, the lever et at 8, and 'the catch 6 at 9, as best shown. in Fig. 2. The link 3 has a spring 3 formed therein, and this serves to take up some of the force of the movement and prevent too violent a pull on the whistle-rod. The usual handle F' is connected to the end of the rod F, by which the whistle may be a 'sounded in the usual manner by hand by the fireman or engineer, and also, through the chain or link 10, be used to disconnect the catch 6, said catch being normally held into engagement by the spring 11.

The operation is as follows: When the locomotive in its course has reached the strike IOO C,itope1'ates the bar or lGVGP D,Which,through the various connections, pulls on the Whistlerod F and sounds the whistle. It at the same tine 'aises the end of the detent 4, so that it engages with the catch 0, and thus the whistlc is held open and continues to sound until said catch is drawn out of engagenent With said detent 4. The pivot S to the lever 4 is preferably in the form of a shaft or rod extending entirely through the cab for con- Venience in making the connections, as the 'od 01' lever D should be at the extreme one side of the loconotive, While the rod F and its handle 1 should nost Conveniently be in the center, as shown.

Obviously, many other arrangenents of 'ods, levers, and links might be employed to acconplish the same result and the pivots and connections be located to suit the arrangenent adopted Without departing froni my invention. I have shown one such ar'angenent in Fig. 4, in which bar D is mounted in slides instead of on a pivot, while the level' 2 is straight instead of angular, and the link l is dispensed with.

Having thus fully described my said invention, What I claim as new, and desire to secure by Letters Patent, is

The combination, in an automatic appa'atus for sounding locomotive-whistles, of a strike positioned adjacent to a railWay-track, a rod or lever suitably mounted on the locomotive and adapted to come in contact with and be operated by said strike, the whistle connections running from said rod 01' level' and adapted to operate said whistle, a detent carried upon a rock-shaft or pivot forming part of said connections, and a catch positioned adjacent to said detent and adapted to en gage therewth, Whereby the Whistle may be held continuously open until pu'posely closed, substantially as set fol-th.

In Witness Whereof I have hereunto set my hand and seal, at Test Point, Indiana, this 19th day of June, A. D. 1897.

HENRY C. MUSTARD.
