To aZZ whom, it may concern:

Be it known that 1, ANDREW A. SMITH, a citizen of the United States, residing at Crested Butte, in the county of Gunnison and State of Colorado, have invented a new and improved Spraying Gar-\Vheel and Spraying-Bar, of which the following, in connection with the annexed drawings and the letters of reference thereon, is a specification.

My invention is intended to overcome the inconvenience, avoid the frequent loss of life or limb, and save much of the expense now experienced with the use of ordinary spraying-pins on coal-cars running over inclined planes or downgrade roads. \Vith the old mode of spraying a coal-car on aninelined or downgrade road it is customary to provide a number of strong wooden pins sharpened at both ends, and the sprayman or person who attends to the running out of the cars runs alongside the train and places a spraypin between the spokes of each of the wheels of a car,-and said pins lock or arrest the revolution of the wheels, and thereby cause the speed of the train to be slackened, the pins by thus locking the wheels causing them to slide with great friction upon the track; and in case it is not desired to stop the train entirely, the sprayman runs alongside the same and at the desired moment pulls out the spray-pins, which operation is often attended with loss of life or limb, it requiring to be performed while the train is moving, and there being a liability of hisslipping and falling in a position where the train may run over him, a casualty which has often occurred. The expense for the wooden spray-pins, owing to their rapid wearing out or frequent breakage and getting lost, is very considerable, it rising as high as from three dollars to three dollars and fifty cents for one carin a year, and the demand for these spraypins is so extensive in coal-region sections of the country that they are shipped as an artiele of trade by the car-load to the consumers.

My invention consists, first, in the combination, with a spraying car-wheel provided with spraying teeth or pins, of a vibrating spraybar applied upon a car, and adapted for working in connection with the teeth or pins formed on the spraying car-wheels, whereby the can wheels can be stopped or started in their revelution in an instant, and the speed of the car caused to be either slackened or accelerated without using ordinary spray-pins or endangering the life of the attendant.

It consists, second, in a vibrating spray-bar applied upon a car, in combination with two pairs of spraying car-wheels, each pair being provided with spraying-teeth of reverse con- 6 struction, whereby a front wheel on either side of a car and a rear wheel on either side thereof, accordingly as the car may be turned around, can be simultaneously sprayed, and thus both the front and rear pairs of wheels 6 locked simultaneously by the attendant from either side of the car.

It consists, third, in a-vibrating spray bar provided with stop-lugs and an extension handle or handles,whereby the bar can be readily 7c operated by an attendant from a position on the ground.

In the accompanying drawings, Figure 1 is a perspective view of a coal-car body provided with my new spraying car-wheels and new 7 5 spray-bar. Fig. 2 is an inverted plan view of the same. Fig. 3 is a perspective view of a modified form ofthe spraying car-wheel. Fig.

4 is an inverted plan of a coal-car, spray-bar, and another modified form of car-wheel; and Fig. 5 is an elevation of one of the ear-wheels shown in Fig. 4:.

In the drawings above described, A is a coalcar body, B B its axles, and O 0 front and rear car-wheels, and D the spray-bar, pivoted at a to the under side of the car-body, as shown. The car-wheels are formed with either a ratchet-toothed tread portion, 0, as in Fig.

1, or with a ratchet-toothed flanged portion, as in Fig. 3, or with strong pins projecting 0 from their inner faces, as shown in Figs. at and 5. The spray-bar at each of its ends is formed with front and rear spraying-lugs, d, and handle-extensions d, which latter extend out beyond the outer faces of the wheels, so that 5 they may be grasped by the attendant without endangering his life or limbs. The lugs d are situated so as to stand between front and rear wheels when the spray-bar lies at right angles to the sides of the ear-body, and so as too to come under the shoulders of the ratchet when such bar lies slightly diagonal with respect to the bottom of the car-body, as illustratedin Figs. 1 and 2 of the drawings.

In order that the ratchet-toothed car-wheels may be locked on either side of the car, and that the wheels of the front and rear axles may be locked simultaneously by the one spraybar, the ratchet-teeth on one of the rear wheels are constructed just the reverse of those on the other, and the same reverse construction is adopted with respect to the front wheels as is illustrated in the drawings.

Beneath the bar D friction-springs f may be applied for the purpose of retaining the bar in its locked or unlocked position.

Instead of the springs, the guide-bars f may be bowed slightly,so as to act bindingly upon the bar D, or other suitable detents may be provided for the like purpose.

In Fi 3 the ratchet-teeth are shown formed on the flange of the car-wheel, and this construction may answer a good purpose; but the construction'shown in Figs. 1 and 2 is far preferable; and, in Figs. a and 5, pins are shown projecting from the inner faces of the carwheels, and this construction may be found preferable to either of the other constructions, as there will be great strength secured, and the pins can be cheaply applied to or cast upon the wheels.

In operating with the invention, the attendant lays hold of one or the other handle of the .spray-bar and moves the bar horizontally on its pivot until the lugs come under the teeth shown in Figs. 1 and 2, or in contact with the teeth shown in Fig. 3, or between the pins shown in Figs. 1 and 5. This adjustment of the spray-bar instantly stops the revoluthe attendant moves the spray-bar at the proper time out of locking relation with the teeth or pins, which adjustment frees the wheels and allows them to revolve, whereupon the speed of the train will become accelerated.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of a horizontally-vibrating spray-bar provided with stop-lugs and applied upon a car,with car-wheels provided with spraying teeth or pins, substantially as and for the purpose described.

2. A vibrating spray-bar, in combination with two pairs of car-wheels, each pair providcd with rcversely constructed spraying teeth, substantially as and for the purpose described.

3. The vibrating spray-bar provided with stop-lugs and an extension handle or handles, substantially as and for the purpose described.
