To aZZ whom, L' may concern.'

Be it known that we, JOSEPH TURNBULL and EDWIN W. FARWELL, citizens Yof the Unit-ed States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have jointly invented certain new and useful Improvements in Snow-Road Machines, of which the following is a specification.

Our invention relates to apparatus for sprinkling roads to cause smooth road-beds to be produced by freezing. Great difficulty is experienced among the lumbermen in providing good roads for hauling logs from the differentplaceswheretrees arefelled toacommon depository. As is well known, the cutting of logs in northern regions is done mostly in the winter, for thereason that it is difficult to transport them except upon sled's, and to use these to advantage smooth road-beds, either of snow or ice, are necessary. And as it frequently happens that there is too little or too much snow to form the desired roadways, it is found necessary to make roads by sprinkling a course and allowing a subsequent freezing to produce the smooth surfaces required. Furthermore, it is found that the roadways so formed are smoother and better for the purpose of hauling logs than when the road-bed is formed merely by beaten snow. Ordinary sprinklers are not adapted to the purpose, because the cold is often sufficient to freeze the water in the apparatus and thus end itsusefulness. In addition to the formation of a smooth track for sleds it is frequently found necessary to remove deep snow from the roadbed and from its sides to facilitate transportation.

It is the object of ourinvention to produce an apparatus adapted to warm water sufiiciently to prevent it from freezing while the apparatus is being operated and also to produce steam when d esired, suitable appliances being provided whereby the road-bed may be sprinkled with the warm water, and when occasion demands jets of steam may be thrown into .the road and to its sides for melting away snow.

Our improvements are illustrated in the accompanying drawings, in whichm Figure lis a plan view of the apparatus; Fig. 2, a side elevatiompartly in section; Fig.

3, a rear elevation; Fig. .4, a top view of the funnel for conducting water into the boiler; and Fig. 5 is a detail of one of the sprinklingnozzles.

In said drawings l designates a boiler, having a semi-cylindrical top and vertical sides 2. A passage-way 3, for the products of combustion, is formed by vertical sides et, separated from but connected at the bottom 'with the outer sides 2 of the boiler, and the s'des 4. are connected at the top by a crown-sheet 5. A continuous water-chamber is thus formed at the sides and over the combustion-chamber. A suitable grate 6 near the rear end is pro-l vided, and also a door 7 for closing the firechamber. At the forward end is connected a smoke-stack 8, having a hinge 9, by means of which its upper portion can be swung rearward. The boiler is supported upon bobsleds 10, or runners of any desired character. Short pipes l1 are connected to the boiler near its middle, and valves l2 are provided for regulating or cutting od the flow of water. From the pipes 11, which may have T-shaped connections 13, there extend downward and rearward pipes 14., which may be provided at their lower extremities with any suitable character 0f nozzles or sprinklers for directing the water downward or laterally.

At the top of the boiler is connected a pipe 15, controlled by a valve 16, for using steam when desired. This pipe has connections 17, extending to the pipes 14, so that steam can be carried to the lower end of the latter pipes.

In using steam for removing snow or other purposes the lower ends of the pipe 14. may be connected by a transverse pipe 18, having suitable perforations for ejecting steam in the directions desired. The pipe 1S and the nozzles 19 may be used interchangeably by coupling them to the pipes 14.- by any of the usual forms of couplings.

The boiler is supplied with water through the funnel 20 in the top.

Devices are shown by means of which a barrel of water can be hoisted and emptied into the funnel. These devices consist of a post 2l, having lateral braces 22, and provided with a pulley 23 at its top, through which a rope or chain may be run for hoisting abarrel to the funnel. A man-hole 24.,

IOO

with which the funnel connects, is closed by a removable plate'25 and secured by any suitable clamping devices 26.

In use Water can be easily kept from freezing While the apparatus is in operation, and in case of the obstruction of the road by snow steam can be readily utilized for removing so much of it as may be an obstruction.

Practical use has demonstrated that the apparatus is highly successful and useful for the purpose for Which it is intended.

Having described our invention, what We claim, and desire to secure by Letters Patent, 1s-

In an apparatus of the character set forth, a portable horizontal boiler having a tine at its base extending from end to end, and
