To all whom, it nuty concern.-

Be it known that we, JOHN LINDALL, residing in Boston, county of Suffolk, and PAUL efficient apparatus especially applicable forremoving snow and ice from the rails of railvways employing electricity as the motive power, and particularly from the third-rail conductor of elevated electric railways. For this purpose a device which is designed to engage the upper surface of the third rail is provided with a handle having cooperating with it means under the control of the operator for elevating the said handle, with which the liftin means may and preferably will be adjustably secured to ermit the cleaning device which engages tlie third rail to be pro erly positioned with relation thereto. T e device which engages the third rail may be held in yielding engagement therewith by suitable means, as will be described. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a side elevation of a' portion of a railway-car provided with an apparatus embodying this invention, the apparatus being shown in its operative position; Fig. 2, a like view with the apparatus in its raised or inoperative position; Fig. 3, an enlarged detail of the apparatus in its operative position; Fig. 4, an enlarged detail of the apparatus in its raised position; Fig. 5, a section on the line 5 5, Fig. 3; and Figs. 6, 7, and 8 details to be referred to.

In the present instance the invention is shown as embodied in an apparatus especially designed for removing ice and sleet from the upper or contact surface of the third rail of an electric railway. For this purpose provision is made for cutting the ice and sleet, and to this end we employ a device herein shown as a brush comprising a body or back piece a, to which is secured a plurality of cutters or clearing members I), preferably thin pieces or bristles of spring-steel, (shown separately in Figs. 7 and 8,) which are of sufficient rigidity to effect a cutting action upon the ice and sleet and yet are sufficiently flexible to permit them to bend or spring under pressure, so as to enable the said cutters to conform to irregularities in the surface of the third rail or conductor.

The body or back piece a has secured to it, as by bolts 0, a reinforcing-piece d, which is electrically separated from the cutters by a layer e of rubber or other suitable insulating material. v

The cleaning device or brush has secured to its back piece d a barf, constituting a handle for the same. The barf is provided at its lower end, as herein shown, with a flange g, which is fastened to the back piece of the brush, as by the bolt h, and the said flange is preferably provided with a groove 0 in its upper surface for a purpose as will be described.

The brush or cleaning device and its attached handle or barf are bodily movable in a vertical direction toward and from the third rail or conductor, (not herein shown,) and the said bar or handle may be guided in its movement by a hollow casting k of substantially the same shape as the bar in crosssection and which is provided with a lip or flange m (see Fig. 5) at its upper end to rest upon a support, which may be the shoe-beam a now employed on the cars of elevated-railway systems for carrying the contact-shoe. (Not shown.)

In the ipresent instance the hollow casting or guide is shown as extended down into a suitable slot or opening 0, formed in the shoebeam, and the flange or lip m is secured to the upper surface of said beam, as by screws p, (see Fig. 5;) but it is evident other forms of support may be used and the casting or guide may be located at one side of said support. The bar or handle f is extended above the support 1?. and has secured to it an operating device, herein shown as a lever g, which is pivotally connected to the bar or handle f of the brush. The operating device or lever 9 may be adjustably secured to the handle f by means of a bolt 10, extended through the operatin device 9 and through one of a series of ho es 12 in the handle The holes 12,

as shown in Fig. 6, are arranged. in two substantially vertical rows, with the holes in one row staggered with relation to the holes of the other row, so that substantially close adjustments of the brush may be made as the bristles or cutting members of the same are worn away.

The operating device or lever may be made substantially oblong in shape, as herein shown, and the pivot 10 located at a greater distance from the bottom of the lever than from the sides of the same, so that said lever when turned into a substantially vertical po sition (shown in Fig. 4) acts as a cam to elevate the cleaning device against the action of a spring 15, which is employed to keep the cleaning device in firm yet yielding engagement with the third rail or conductor. The spring 15 may be made as herein shown and consists of a piece of steel-wire rod having one end secured to the support a, as by the staples 16, and preferably, also, by bending the end of the wire rod and driving the same into the support, as represented in Figs. 3 and 4. The wire rod 15 may be provided with one or more coils 17, and its free end 18 is designed to rest upon the flange g of the handle or barf and to be guided by the groove iwhen the free end of said spring is moved toward or away from the support a under the influence of the brush.

In Figs. 1 and 3 the cleaning apparatus is shown in its lowered or operative position and in Figs. 2 and 4 in its raised or inoperative position.

In practice the brush is adjusted withErelation to the third rail, so that the lower ends of the bristles will exert a cutting action upon the ice or sleet, and the said bristles are made substantially stiff to perform the cutting action desired, yet are of sufficient flexibility to permit them to bend under pressure, so that when the third rail is worn and uneven the bristles brought in contact with the high points of the rail may yield or bend sufficiently to enable other bristles to be brought in contact with the lower points of the contact-surface of the rail, thereby insuring effective cleaning of the contact-surface of the rail.

The cleaning device is herein shown as a brush provided with bristles or wires, and

while this construction may be preferred we do not desire to limit ourselves to this particular construction of cleaning device, as the other parts of the apparatus may be used to advantage with other forms of cleaning devices.

In Fig. 3 the lever g is extended transversely of the handle f and its flat under face engages the upper surface of the shoe-beam or more properly the'flange or lip ra thereby retaining the said lever in this position until positively moved.

In Fig. 4 the lever 9 extends longitudinally of the handle f, and its flat end engages the lip or flange m and retains the said lever in this position until positively moved.

In both instances the lever q acts to limit the downward movement of the brush by the spring, yet permits the brush to be moved upward by elevations in the third rail. The lever g practically forms a cam having two substantially flat faces to engage the upper surface of the support, and in order to prevent the cam from being automatically turned from its horizontal position (shown in Fig. 3) into its vertical position (shown in Fig. 4) by the weight of the cam in case the brush should be elevated sufficiently to permit such movement by an elevation in the third rail a counterbalance or weight for said cam is provided, which counterweight is shown as the handle or prolongation of the lever q.
