JOHN I-I. MORSE, OF EVANSTON, ILLINOIS.

SAFETY-GATE.

SPECIFICATION forming part of Letters Patent No. 417,740, dated December 24, 1889.

Application iiled March l2, 1889. Serial No. 308,001. (No model.)

.To all whom it may con/cern:

Be it known that I, JOHN H. MORSE, of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety-Gates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a longitudinal sectional view of a railway road-bed, showing the gates upon one side embodying my improvements. Fig. 2 is a sectional plan View in detail taken upon the line 0o x, Fig. l; and Fig. 3 isa transversef sectional View ot' a railway# crossing, showing double gates and a raised platform for use in operating said gates in unison.

Like letters of reference in the different figures indicate like parts.

The object of my invention is so to construct railway safetyegates that all their working parts may be above ground and so simplified and arranged that they may be cheap and durable and not liable to be obstructed by accumulations of ice or snow.

IVith this end in view my invention consists in the combination of elements heremore particularly described and and are provided with iianges Cl, d., which are' bolted to sills B, embedded in the ground.

Each gate consists of two metallic bars C C, which are trunnioned to the posts A A at or near the top, by means of trunnions c c, said bars being arranged to move in planes parallel to those of the posts A A, and being connected to each other by means of a crossbar C, long enough to extend across the street, which forms the gate proper. One or more additional bars may, if desired, be placed across parallel with or in other positions with relation to the bar C to render the gate more noticeable. Oblique braces c2 c2 are also employed to impart to it the required stiffness. The posts A are made of a sufficient length and the gates trunnioned therein at points suliiciently high to permit all ordinary vehicles or objects to pass beneath the gate when elevated, as shown in Fig. 3. The shafts or trunnions c c are attached rigidly to the bar C and are journaled in bearings formed in plates c3, Fig. 2, which are riveted to the posts A A.

To enable said gates to be operated with ease, I prefer to attach counterpoise weights c4 c4 to the protruding ends of the bars C. Preferably midway between the posts A VA, which are upon opposite sides of the railway-tracks, I place a post E, to which may be attached a platform FV for the gate-keeper. The post E is connected with the posts A A by means of bars e e. Loosely mounted upon a bearing secured to the post E is a gear e', into which meshes a pinion e2, operated by means of a crank dil. Upon the gate-trunnions o c are attached pinions c4 o, which mesh into segmental gears g g, mounted upon the posts A A. Vrist-pins g lg upon the the gears g g are connected, respectively, with like wrist-pins e2 e3 upon the gear-wheel e by means of rods h h. Thus it will be seen that upon turning the crank d4 the gates are simultaneously moved in opposite directions through said gears and rods. Springs d3 d3, Figsl and 2, are preferably interposed between the bars C C and the posts A.

The advantages of my improved gate are that it is simple, strong, and durable, easily constructed and operated, and is capable of being repaired, if necessary, without in any way interfering with the railway-tracks. It is, moreover, applicable for use at bridge-approaches, or wherever it is necessary to impede temporarily the passage of persons or vehicles.

Having thus described my inventiom I claim- The combination, with the trunniened counterpoised gates mounted upon the posts A A, of the gears c c g g, gear e', mounted upon an intermediate elevated support, bars 7L h, In testimony whereof I have .signed this connected at one end with the gears g g, as speeiiieation, in the presence of two Subsorib- 1o showgn, and Connected with tille gear one ing Witnesses, this 7th day of Maroh,1889.

at e and the other at e anc a eran c an( i i gear in operative connection with the gear e', JOHN H' MORSE' whereby upon the turning of said crank said WVitnesses:

gates ina-y be rotated in opposite directions, D. H. FLETCHER,

substantially as shown and described. J. HALPENNY.
