SAFETY-GUARD.

SPECIFICATION forming part of Letters Patent No. 768,480, dated August 23, 1904.

- Application filed March 23,1904. Serial No, 199,605. (No model.)

To all whom it may concern:

Be it knownthat 1, WILSON KINeMAN PAGE, a

citizen of the United States, residing at Olean,

in the county of Catta'raugus and State of New York, have invented a new and useful Safety- Guard, of which the following is a specification.

This invention relates to safety-guards for" 'ing a novel form of guard to bridge the crossmg, the guard to be of such construction as to constitute a perfect conductor for the current should the trolley-wheel leave the trolley-wire, to reduce the weight of the guard to a minimum, to prevent vibrations due to wind-pressure, thus relieving the trolley and guy wires of dangerous strain, to prevent any accumulation of snow by the guard, which would have a tendency to weaken the poles and guy-wires, to facilitate shipping and handling of theguard, and to reduce to the minimum the noise due to contact between the trolley-wheel andthe guard.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction andcombination of parts of a safety-guard for trolley-wires, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate correspond-- ing parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that various changes as to shape,

Fig. 2 is aview in side elevation of a slightly-modified form of guard.

, Referring to the drawings, 1 designates the body of the guard, the' same being constructed of meshed wire of any required gage, and 2 terminal arches or yokes to which the wires of the body are connected in any preferred manner; The yok'es are by preference made of wrought iron and are arch-shaped in elevation and provided with lateral strengthening-flanges 3 to render thestructures rigid in character. The wire of which'the body is constructed may be of any suitable kindsuch, for instance, as galvanized-iron wire to present a non-rusting structure. The'lower end of each of the yokes-is formed into an eye or keeper 4, in which are held longitu-' dinally disposed brace-wires 5, the ends of which are formed into eyes 6 to provide a means of attachment for guy-wires which are provided for the purpose of holding the guard against longitudinal vibrations in operation. As shown in Fig. 1, but two arches or yokes are employed; but if found necessary to impart additional strength to the guard intermediate yokes may be employed, as shown in Fig. 4, wherein four are exhibited. Through the crests of each of the yokes extends an eyebolt 7, to the lower end of which is connected a hanger 8 for supporting the trolley-wire 9, the eyes being engaged by supporting-wires for holding the guard in proper position. It will be noted that the hanger is in contact with the wires of the body of the guard, and by this means the guard is charged, so that in event of the trolley-wheel jumping from the trolley-wire the current will besupplied as usual, and thus positively obviate any danger of a car becoming stalled on a crossing. As these guards must of necessity be of considerable length wherev employed in bridging, say, two tracks, it follows that they should be made as. light as consistent with the work to be done, not only to relieve the poles, guywires, and trolley wires of objectionable weight, but also to reduce the cost of application of the guard to the line. In addition it is desirable to prevent accumulation of snow or ice upon the guard, which would greatly add to its weight, and a final object is to reduce the vibration to a minimum. All of these results are secured by making the body an open-Work strueture,which will allow wind to pass therethrough, and thus prevent vibrations, and will positively prevent accumulation of snow and ice to such an extent as to be objectionable. Further, by making the body of woven wire space in shipping is saved and handling is facilitated, as the yokes and body portion may be shipped separately and assembled at the place of use. In addition to the brace-wires 6 for engagement by guy-wires to brace the structure the yokes near their terminals are provided with openings 10, with which can be combined other guy-wires, which operate still further to brace the structure against vibration and liability of sagging in use.

As seen by reference to Fig. 2, the structure is arch-shaped in cross-section, and the trolley-Wire is disposed at the crest, and by this arrangement should the trolley Wheel jump the trolley-Wire it will be positively held from becoming disengaged from the guard.

Having thus fully described my invention, what I claim is l. A guard of the class described embody.- ing an open-work body or conducting portion, and trolley-wire hangers combined with the upper portion thereof.

2. A guard of the character described embodying an open-work body or conducting portion, and trolley-wire hangers associated with the crest thereof.

3. A guard of the class described embodying an open-work body or conducting portion, and terminal trolley- Wire hangers associated with the crest thereof.

4. A guard of the class described embodying an open-work or conducting portion, yokes with which the body portion is combined, and trolley-wire hangers carried by the crests of the yokes.

5. A guard of the class described embodying an open-work body or conducting portion, terminal yokes With which the body portion is combined, and trolley-wire hangers carried by the crests of the yokes.

6. A guard of the class described embodying an open-work body or conducting portion, terminal yokes with which the body portion is associated, trolley-wire hangers supported by the yokes, and longitudinallydisposed brace-rods combined with the yokes and provided with means for attaclnnent to guy-wires.

7. A guard of the class described embodying an open-work body or conducting portion, yokes to which the ends of the body portion are associated, the terminals of the yokes being formed into eyes or keepers, and longitudinally-disposed brace-rods engaging the keepers, and provided with means for attachment to guy-wires.

8. A guard of the class described embodying an open-Work body or conducting portion, yokes associated with the ends thereof, the terminals of the yokes being formed into eyes, an eyebolt passed through the crest of each of the yokes, trolley-wire hangers held in place by the eyebolts, and longitudinallydisposed bracerods engaging the yoke-eyes and provided with means for attachment to guywires.

9. A guard of the class described embodying an open-work body or conducting portion, yokes associated with the ends and intermediate portions thereof, the terminals of the yoke being formed into eyes, an eyebolt passed through the crest of the yokes, trolleywire hangers held in place by the cyebolts, and longitudinally-disposed brace-rods engaging the yoke-eyes and provided with means for attachment to guy-wires.

10. A guard of the class described embed ying a plurality of yokes the terminals of each of which are formed into eyes, an eyebelt passed through the crest of each of the yokes an open-work body or conducting portion d isposed on the inner sides of the yokes, trolleywire hangers clamped against the conducting portion by the bolts, and longitudinally-disposed brace-rods engaging the oke-eyes and provided with means for attachment to guywires.

In testimony that 1 claim the foregoing as my own Ihave hereto allixed my signature in the presence of two witnesses.
