Application ledfJuly 30,

The primary object of thisinvention isto providek a mowing machine for use onra1l- Ways for mowing the grass' andweeds from between the rails of a track and from a.V strip along each side of the track.- z

Another object of the invention is to pro- `vide a truck for carrying the mowing attachment and which is arranged to engage the rails of the track and which is provided with amotor for propelling the sameandfor actuating the cutting knife or knives.

A further object of the invention is to provide means for raising the knife carrying part when the mower is not tobe used.

Thisinvention also consists in certain other features of construction and in the coinbinaf' tion and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed Aout inthe appended claims.

` In describing ray-invention in detail, refer ence will be had to the accompanying drawings wherein like characters denote like or corresponding parts .throughout the several views, and in which Figure l is an elevation of the invention.

Figure 2 is a plan view.

Figure 3 'is a plan view of the tiltable frame which carries the mower mechanism.

Figure 4 is an enlarged plan view showing a portion of the cutting means and the cylindrical cam for operating the same. K

Figure 5 is a section on line 5 5 of Figure 4. y

.Figure 6 is a Section on line 6 6 of Figure 5. l

Figure 7 is a sectional view through the combined pulley and clutch.

Figure 8 is aview of the driving means from the motor to the rear shaft. v

Figure 9 is a view of the means for shifting the clutch member of said driving means.

In these views, 1 indicates a wheeled truck,` the wheels of which are designed to engage f the rails 2 of a track so that the device can be used on railroad tracks, electric car tracks and the like. A motor 3 is carried by the truck and the shaft of the motor is connected by the gears 4 with avertie-al shaft 5, which has a beveled pinion 6 at its lower end for engaging either one of a pair of beveled gears 7 which are slidably mounted on the rear axle of the truck and which are movable lby the links 8 which arel connected with the hand lever 9. Thus the truck can be driven in either direction by the motor or by moving i924. sensi No. 729,157. l

the gears 7 to a neutral positionthe truck can be freed from the motor. A shaft 10 is l-horizontally arranged adjacent'the front end of the truck and a framing consisting of the arms V11 is pivotallymounted on said shaft.

Tlieaprms are spaced. apart. by the sleeves 12 r and a combined pulley and friction clutch 13 with which is associated the sprocket 14 is mounted on said shaft, ball .bearings 15,

being arranged between the .sprocket andthe small sleeve to take upthrust. A belt 16 passes over the pulley andover-a pulley y1 7 on the motor shaft. A hand lever 18 is connected with the pulley by meansof the links 19 so that said pulley can be shifted into and Vont of `fngagement with the clutch part to which the sprocket is connected. Y The rod 20 i to whichthc levers l9 and 18 are pivoted has arms 21 thereonl which engage grooves 22 in the extended part of the outer arms 11 so that when the shaft is-rocked by means of the hand lever 23 the frame formed by the arms 11 will be tilted so as .to place the mower parts in operative or y inoperative position, as shown in full or dotted lines in Figure 1. An L-Shaped supporting member 24 is bolted to the fianges 25 on the outer ends of the arms 11 and this member' forms. a support for a T-bar 26, blades 27 to which the cutter bar 28V is fasten-ed anda driving bar 29 which is fastened to the cutter bar. The supporting member also carries the wear plate 30 for the n blade. and a plate 31 is fastened to the pro-` jecting part of the T-bar and extends down close to the blade for acting as a shield for the cutter bar and rear part of the blade. The usual plate guide and cutter bar protectorv 32 are fastened to the T bar and the outer edge of the. support-ing member. The

blade is' reciprocated by means of a cylinder movement to the driving bar which in turn moves the cutter bar and the knife blades so that the cutting edges of the knives cooperating with thel fingers formed on the supporting member will cut the weeds and grass between the rails and in a strip at the From the foregoingl it will be seen that I'V have provided a simple arrangement of parts for cutting the Weeds and grass between the rails and at each side of a track. rI`he apparatus is mainly intended for use in tropical countries where the weeds grow abundantly and considerable labor is required to keep them out. The stubble left by the machine acts to prevent the ballast from being washed out by heavy rains and by cutting the weeds the decay of the track parts is checked as they can quickly dry out after rains.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the sever-al parts, provided that such changes fall Within the scope of the appended claims.

Ihat I claim is l. A mowing apparatus, comprising a truck having its `wheels arranged to engage the rails of a track, a frame pivoted at the front of the truck and extending downwardly,

a supporting bar at the front of the frame formed in sections, with one section between the rails and the others at the outer sides of the rails, cutting means carried by each sec tion of the bar, rollers on the frame for engaging the rails, a motor on the truck, means for propelling the truck from the motor, means for actuating the cutting means from the motor and manually operated means for tilting the frame.

2. An apparatus of the class described comp'rising a truck, a motor thereon, meansV for propelling the tru-ck from the motor, a shaft carried by the truck, a combined clutch and pulley on the shaft, a belt for connecting the motor with the pulley, manually operated means for shifting the clutch parts, a sprocket connected with a clutch part, a. frame pivotally mounted on the shaft, and having rear eX- l tensions thereon, cutting means at the front end of the frame, an actuating member for the same, al sprocket associated with the actuating member, a chain connecting the sprockets, track engaging wheels carried by the frame, a shaft, arms thereon engaging the rear extensions of the frame and a hand lever connected with the shaft for tilting the same.

f In testimony whereof I aiiix my signature.

MARIANO SALAS.
