PROTECTIVE SWITCH MEMBER Application filed October 14, 1929. Serial No. 399,438.

The above and other objects will become apparent in the description below in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a perspective view of the switch apron as applied to its proper position between parallel rails at a switch location.

Figure 2 is a longitudinal, sectional, side elevational view of Figure 1.

Referring in detail to the drawing, the numeral 10 indicates one of the rails of a track system. This rail is curved at the switching position and branches to another parallel track system adjacent. The numeral 11 inclicates a substantially straight linear rail which forms the companion member of rail 10. These rail members, 10 and 11, are mounted on a plurality of side by side arranged ties 12 which are conventionally set upon a bed of ballast stone. The rail 10, which branches to an adjacent pair of rails, is rigidly mounted upon the ties and the rail 11 is also mounted on these ties in the same condition, that is, rigidly. In switching or shifting railway carriers from one pair of tracks, such as indicated'by the numerals 10 and 11, to an adjacent pair of tracks, movable switching rails are used. rails is indicated by the numeral 13. Said switch rail is connected to a rigid branch rail 14 by straps15 in the conventional manner and is capable of lateral movement. The

tip 16 of the movable switch rail 13 tapers gradually to a point and is adapted, when the switch is set, for shifting, to lie adjacent the side face of the railll. This position is not shown in Figure 1.

The opposing switch rail is indicated by the numeral 17 and is shown in a position lying adjacent the curved stationary rail 10. These One of these movable

switch switch rails

13 and 17 which shift carriers 7 from'one set of rails toan adjacent set are actuated by a switch lever not shown on the drawing. The switch mechanism comprises a strap 18 which is connected by brackets 19 to a connecting rod 20. This connecting rod joins the

switch rails

13 and 17 at the free ends thereof and, being very delicate, is

readily injured or deformed causing open switches.

The invention consists in providing an apron whichrises to the level of the carrying surface of the

rails

10', 11, 13 and 17. The apron comprises a horizontal plate 21 which covers the switch rail operating mechanism and is supported upon high beams 22 and23. This plate is recessed at 24 and 25 on opposing sides thereof in order-to permit the pas- .sage of the tips of the

switch rails

13 and 17 into these recesses alternately according to the direction in which the carriers are to pass. The protective plate 21 is provided with inclined aprons 26 on opposite sides thereof-which have extensions 27 thereon secured in place upon a convenient tie by bolts 28; Ledges 29 are provided at the extremitiesof the aprons which form shoulders .for locating the; protective member supporting ties 30.

t has been established by railway engineers that wrecks and derailments occur through reason-of faulty switch units. The

switch rail operating mechanism is generally rendered faulty by passage of the proceeding carrier or train. It frequently occurs, 'especially on freight trains, that partsof the suspended mechanism, such as brake beams or the'like, will dragat one end and, in pass ing over the switch crossing, comein contact with the .swit h ope'rating mechanism with the consequence that the switch operating mechanism is either badly deformed or fractured. Theltra'in .crew or switch operator who reverses the switch for shifting when using the switch upon an ensuing occasion 'willnotnotice this deformed switch and will shift the

rails

13 and 17, one of which, with the connecting rod 20 deformed, will not come in contact with its cooperating stationary rail, either 11 or 10. When this occurs, one

switch rail will not perform its function with a consequent derailment of the carrier passing through the switch. To prevent this dangerous and property destroying derailment, I provide a raised member 21 from which inclined aprons 26 extend and are mounted upon the ties on both sides of the switch rails. These members completely guard, conceal, cover and protect the switch operating mechanism and, should any dragging'devices on the carrier exist which is be ing drawn over the switch, theywill be lifted by the protectivejmember over the mechanism concealed thereunder and will, therefore, be

prevented from injuring this mechanism.

It is to be noted that certain changes in form and construction may be made wlthout departing from the spirit and scope of the invention.

' I claim: i i

1. A device of the class described comprising in combination a straight linear rail, an adjacent angular movable switch rail, a companion curved stationary rail, and a companion switching rail mechanism for switching'said switching rail, ties supporting said rails, inclined aprons mounted on said ties and a horizontal plate unitary with said apron joining the same and raised above the switch rail operating mechanism for protecting the same, recesses in said plate for receiving the switch rail end therein when said switch rail is in opened position.

2. A device of the class described comprising in combination a straight linear rail, an

, adjacent angularmovable switch rail, a companion curved stationary rail, and a companion switchingrail mechanism for switching said switching rail, ties supporting said rails, inclined aprons mounted on said ties and a horizontal plate unitary with said apron joining the same and raised above the switch rail operating mechanism for protecting the same, a recess on each side of said plate, either of said recesses being adapted to alternately receive one or the other of said switch rails when said switch rail mechanism is operated.

3. A device of the class described compris- .ing in combination a straight linear rail, an

adj acently positioned angular movable switch rail, a companion curved stationary rail and a companion switching rail, ties supporting said rails, inclined aprons mounted on said ties and a horizontal plate unitary with said apron j oining said aprons at their upper ends,

said plate being raised above the switch rail operating mechanism for protectmg the same, a recess on each slde of sald plate extending in the same general direction as the rails, said recesses being adapted to alternately receive one or the other of said switch rails when said switch rail mechanism is operated.

In testimony whereof I afiix my signature.
