SNOW MELTEB.

Application filed October 23, 1926. Serial No. 143,552.

Our invention relates to a novel construction of a snow melter, wherein we employ a tractor having a suitable frame mounted thereon, said tractor carrying blowing and heating means, whereby the hot gases and products of combustion after being conducted longitudinally through a suitable upper flue are conducted downwardly to a hood of our novel construction, said hood being composed of a suitable rear stationary or body port-ion and a front section hinged to said body portion, whereby the products of combustion and hot gases can be readily directed to the desired point upon the accumulation of snow or ice which it is desired to melt.

Our invention further consists of novel means for elevating the front or hinged member of the hood and of a novel damper construction, whereby the products of coinbustion can be quickly and instantly deflected to the desired point or points within the hood. I

It further consists of novel means for supporting the hood and its adjuncts.

It further consists of other novel features of construction and advantage all as will be hereinafter fully pointed out in the specification and claims appended thereto.

For the purpose of illustrating our invention we have shown in the accompanying drawings one form thereof which is at present preferred by us, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which our invention consists can be variously arranged and organized and that our invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Figure 1., represents a side elevation of a snow melter embodying our invention, showing in dotted lines one form of a tractor and supporting frame which maybe employed.

Figure 2, represents on an enlarged scale a bottom view of our novel hood.

Figure 3, represents a section on line 33, Figure 2.

Figure 4, represents a top plan View of the hood in detached position.

Figure 5, represents a section on line 55 showing the damper actuating means.

1 designates our novel construction of a hood for a snow melter, the same comprismg the inlet portion 2, having an opening 3 into which the inlet pipe 4 leads, whereby the hot gases and products of combustion are discharged into the interior of the hood. The hood is composed of a stationary body portion comprising the rear wall 5, and the side walls 6, which preferably slope downas will be understood from Figures 1 to 4. In front of the inlet 2, we locate the horizontal transversely extending flange or bar 7, to which is hinged the parallel, horizontally disposed bar 8 by means of the hinges 9, which may be three or more in number as shown in Figure 4. 10 designates the movable front hood section which is se cured to the bar 8 and comprises the downwardly and forwardly sloping body portion 11, which terminates in the front pendant flange 12 which merges into the sides 13 which are positioned outside of the stationary wings 14 which serve as guides for said sides 13 and which tend to prevent sidewise escape of the hot gases and products of combustion from the side of the hood, when the front section 10 thereof is elevated as seen in Fig. 1. 15 designates a vertical internal partition extending transversely of the stationary hood member in proximity to which located the damper 16, which is pivotally mounted in any suitable manner and is actuated by the handle 17 carrying the ratchet 18 which is controlled by the pawl 19. The damper 16 is so located that in one of its extreme positions it will contact with the wall 5 as seen in full lines in Figure 3, and in its other extreme position it will contact withv the transverse partition 15 as seen dotted in Figure 3. V

It will be apparent that the front movable section 10 of the hood can be actuated by any suitable means, and in practice, as said hood section is rather heavy, we employ the raising and lowering'means seen in Fig ure 1, and comprising the chain or connectherebetween.

tion 20, one end of which is fastened to the front of the movable section 10 at the point 21, said chain passing over the pulleys 22 and 23, seen in Figure 1, and having its opposite end fastened to the Windlass or winch 24:, which is operated by the handle 25. able, hood sectio i 10 can be readily raised and lowered according to requirements.

Our novel snow melter can be mounted or transported upon any suitable frame or tractor and in the present instance we have shown in dotted lines a conventional form of tractor26, carrying a suitable frame 27, on the upper portion of which is carried the upper horizontal flue 28 into which the hot gas is introduced at the point 29 through the valved conduit 30. The upper horizontal flue 28 is connected with the vertical line member l and thereby the products of com bustion and the hot gases are conducted to the inlet 3 into the interior of the hood memher 1. 31 designates the accumulation of snow or ice which is to be melted. The

hood can be supported from the front of the frame 27 by any suitable means, and at the lefthand of'Fig. 1, we have shown one form of supporting devices, which may be employed, such as the

rods

32 and 33, the latter being arranged in pairs as will be understood from Figure at and said rods may be further provided with the turnbuckles 34: and 35, the rear ends of said

rods

32 and 33 being pivotally supported at the

points

36 and 37 respectively. V

For the purpose of reinforcing the rear of the front movable hood section 10 we may employ the horizontal strip or bar 37* seen in Figures 2 and 3,said bar 37* being under the strip or bar 8 and being secured thereto by the fastening devices 38 which pass through both bars 8 and 37 and the rear portion of the hood section 10 clamped Underneath the bar 7, we may also employe the bar or strip 39, as seen in Figures 2 and 3, said bars 7 and 39 being secured together by rivets or other fastening devices 40 as seen in Figures 2 and 4.

By this means a rigid and reinforced construction is provided at the points where strength is needed. It will be apparent that by our novel hood structure when the parts are in the position seen in Figure 3 and the damper is in the position seen dotted, the hood can be employed as a pavement heater, and when the damper 16 is moved into the position seen in full lines in Figure 3, and the front hood section l0'is elevated into the position seen at the left of Figure 1, the device can be employed as a snow melter, and it will be apparent that the hot gases and products of' combustion can be discharged so as to impinge directly'upon the accumulation of snow and ice, as indicated By this construction the frontmov at 31 which it is desired to melt, and the same will be instantaneously melted as is evident. If the snow or ice to be melted is not deep, it will be apparent that the front hood section 10 can stand about in the position seen in Figure 3, and as the tractor 26 and its adjuncts aremoved forwardly, the snow and ice under the hood 1 subjected to the intense heat thus applied will be immediately melted. The front hood section 10 can be elevated to any desired height, as

is evident, and the provision of the side wings 14% will prevent the heat from escaping sideways from the hood when the front section thereof is partly elevated.

' It will be apparent that any suitable form of tractor may be employed and that the supporting frame 27 can be differently constructed if desired and the supporting bars or rods 3-2 and 33 can be differently arranged and assembled if desired.

It will now be apparent that we have devised a novel and useful construction of snow melter, which embodies the features of advantages enumerated as desirable in the statement of the invention and the above description and while we have in the pres ent instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrilicingany of its advantages.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is
