Specification of Letters Patent.

-Application filed September 4, 1914. Serial 0. 880,306.

To all whom it may concern:

Be it known that I, NAMAKA L. FAUFATA,

a citizen of the United States, residing at Paia, in the county of Maui and Territory of Hawaii, have invented certain new and useful Improvements in Railroad Applh ances, of which the followingis a specification, reference being had to the accompanying drawings.

This invention relates to certain improve- .ments in railroad appliances and has relaacter wherein the operating circuits therefor are under control of a semaphore or the like and whereby said operating circuits can be closed only when thelsemaphore or the like is at a predetermined adpistment.

It is also a further object to providean appliance of this general character having novel and improved means whereby the operation of the brakes of a train may be automatically set upon the train passing beyond a given point and whereby such means may be substantially automatically reset upon the release of the brake.

The invention consists in the details of construction and in the combination and arrangement or the several parts of my improved railroad appliance whereby certain important advantagesare attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all aswill be hereinafter more fully set forth. c

The novel features of the invention will be carefully defined in the appended claim.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying d1 awings, wherein--.

Figure 1 is a diagrammatic view oi an ap pliance constructed in accordance with an embodiment of my invention; Fig. 2v is an elevational view, illustratin the means herein embodied for operating t e brake controlling means; Fig. 3 is a view in elevationof the mechanism herein embodied for controlling the brake mechanism. a

As'disclosed in the accompanying -draw ings, 2 denotes a rail of a trackstructure, and 3 a semaphore disclosed in the accom v panying drawings as adjusted into a posi-" tion indicative o danger. The operation of this semaphore forms no part ofmy present Patented July e, 1915.

invention and for this reason it is thought I that a detailed description thereof is unnec essary, other than to state that it is under control ofthe semaphore rod 4 disposed upwardly within the standard 5 and has afiixed thereto the contact 7 adapted to be in en-' gag'ement with the stationary contact 9, supported by the standard 5 when the semaphore is in its tinned.

70, position hereinbefore men- The contacts 7 and 9- are electrically connected, as herein disclosed, through the medium of the conductor h and 2', respectively, with the brush 10 and the rail 2, the brush 10 being positioned in close proximity to said rail 2 of the track-way. The brush l0 is adapted to be engaged by the shoe 11 carried by the locomotive L and of a construc-.

tion and arrangement substantially identical as the shoe 11, hereinbe'fore referred to, and said shoe is electrically connected through the medium of the conductor j with theelectromagnet E mounted upon the base 72, said base in actual practice being preferably positioned within the cab of the locomotive.

The electromagnet E is also electrically connected with the rail 2 through the mediumor" the conductor [a in a conventional man-' ner, and, as herein embodied, the conductor is has interposed therein the source S or electrical energy. By this arrangement, it

will be seen that with the semaphore a position indicative of danger and the s 00 11 in contact with the brush 10', the circuit thus closed will impart movement to the armature A, said armature being herein disclosed as pivotally supported by the up standing arm 73 carried by the base 72 and provided with the rock arm 7i which is operatively connected, as at 75, with the 5 latch bar 76, the free extremity whereoi being adapted to coact wit; the latch 7? carriedby the vertically movable member 78 to normally hold such member 78 in an elevated position. As herein disclosed, the

10 member 78 is slidably supported within the guide 79 carried by a standard 80 projecting upwardly from the base 72, and said upright 80 is also provided with the upstanding arm Sl provided with a suitable opening 82 5 through which projects the bar 76 whereby said lever is maintained in proper position.

The lower extremity of the arm 78 is operatively engaged with the movable contact I 83, and upon release of the member 78 such contact 83 is caused to engage the stationary contact 84, and said contacts 83 and 84 are electrically connected through the medium of the conductors Z and m, respectively, with the winding or coil JV, and the conductor m has interposed therein the source S of electrical energy, and when the winding or coil circuitis closed, the core or solenoid 85 is caused to engage the pivoted latch member 86, carried by the handle 96, and disengage the same from the handle lever 87, herein disclosed as pivotally engaged intermediate 'its'length with the standard 88 projecting upwardly from the base 89, on which base the standard 90 of the coil or winding d is also secured; The outer extremity of the handle lever 87 has operatively engaged therewith through the medium of the adjustable hook member 91, one extremity of the retractable member 92 herein shown as a 0 coil spring, the opposite or lower extremity of such member 92 being connected with the hook member 93 projecting upwardly from the base 90. 'l he member 92 possesses such tension as to rock the lever 87 when released and cause the same to engage the upper extremity of the stem 94 of the check valve 95, whereby air is caused to discharge from the main line of the brake system and the brakes caused to be set. its the particular construction of the brake system forms no part o'fmy invention, a detailed description or disclosure thereof is believed to be unnecessary. I

. The handle 96 is pivotally engaged with the standard 88 and is normally maintained in a horizontal position through the medium of the spring latch 97 operatively supported by the standard 98, and in order to release the brakes, the latch 97 is disengaged (so through the medium of the push rod 99 and the handle 96 moved upwardly until the latch 86 engages "helever 87 and. whereupon the handle returned to its normal post upward movement imparted to posed therein, a lev 2E Ur) through the stander l 88 and the conductor n with the stationary contact 196 with which is adapted to coact the movable co m tact 101 also carried by the member The movable contact 1.01 is electrically nected with the electromagnet E thro" the medium of conductor o, magnet E is also electrically cc in through the medium of th cond and (1 with the contact 1612 gaged by the 163 the handle 96, and the co results in movement herein disclosed as pivotal termediate its length b t. projecting upwardly having its rear end provided L standing projection 10o to the projection 196 by t e 78 whereby said memb engage the contacts 83, h

the member 78 th be operatt the bar 76, as believed to o parent to those skilled in my present invention appertainsa find it of advantage to have con provided with the peripher i so that normally the circ magnet E is broken. lntcrgiosed ductor n is the source S electrical on 78 being sufiicient cause From the foregoing" descripti 00 thought to be obvious ti Zr ance constructed in accor H. vention is of an extremely simple paratively inexpensive nature ticularly well adanted .05

the convenience and faci may be assembled, it vious that my invention is so some change and modification rial departure from the pririci spirit thereof and for this reason do wish to be understood as limiting my the precise arrangement and form. the'several parts herein shown in car out my invention in practice.

I claim:

' In combination with an air bra including a main line having e vs supported for iior lo movement,'a handle .11 17:: l ho- Mn i said nan e or or anc be c inst named one to the other wh reby the sam caused to move in unison and 1 general direction, mean ir pendent movement when the locking ie-ewe said first named lever may engage and force the valve into open adjustment, electrically controlled means for releasing the locking means, said electric means including a circuit closer, separate electrically controlled.

means for operating the circuit closer, and an additional electrically controlled means for returning the second named electrically controlled means to normal position, said last named electric means including a cir- 1o cuit closer wherein one of the contacts is carried by the handle lever.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses. NAMAKA L. FAUFATA. Witnesses:
