Patented Dec. 5, `1944 UNITED STATES PATENT QFFICE sNoW MELTING' DEVICE Ernest S. Powell, St. Paul, Minn. Application March 5, 1941, serial No. 381,771
(ox. 12e-343.5)
` 3 Claims. My invention relates to a snow melting device, wherein it is desired to provide a device found necessaryto remove the snow from the streets so that travel may proceed in an orderly `manner and Vehicles may park along the curbs in the usual manner.
In most cities it. is common practice to lift the snow, either manually or by conveyer belts and to dump the snow into trucks and to haul the snow to a dumping ground. Not only is this hauling of the snow a costly operation, but it is also diflicult to dispose of the snow in the vicinity where it is removed, often making long hauls necessary, and therefore requiring considerable equipment. Attempts have been made to melt the snow `and to allow the water to drain into the gutters of the street or into the sewer system. Because of the low temperature which usually prevails after a snow storm, this method of disposal is often inconvenient, as the water freezes as quickly as it is released from the heatlng chamber. As the water is hauled to sewers considerable time is wasted and .considerable eX- pense is involved in hauling the water and in maintaining the same heated `until it canbe drained into the sewer. I
It isthe object of the present invention to provide a device for melting snow and ice, which not only melts the snow andice, but transforms the same into steam and Water vapor which is dispelled into the air. This device not only disposes of the snow and ice, `but renders unnecessary the problem of disposing of the water thus formed. I have found that while considerable heat is necessary to transform snow into Water vapor and steam, this` cost is'often times not as great as the cost of hauling or otherwise disposing of the snow.
. It is a feature of my invention to provide a container which may be self-propelled, or it may be drawn through the streets of a city, and in general is in the form of a tank to receivethe snow and ice. This snow and ice is inserted into the tank at one end thereof, and the tank is provided with a series of bailies which direct the movement of the water moving from one end of the tank toward the other. As thetank' is heated to a high temperature, this long period of time, during which the water contacts the heated surface of the tank, transforms the water into steam and water vapor. l
' It is a further feature of my invention to provide a tank or container for receiving snow and ice to be melted, which includes a series of outwardly extending pipes or tubes through which heated air may pass. These tubes are positioned in the path of movement of the liquid and greatly increase the area of metal with which the snow, ice, and water contact during their movement from one yend of the tank to the other.
It is a further feature of my invention to provide atankfor melting snow and the like, the base of which is preferably ona slight angle to the horizontalV so that the snow and Water will travel slowly from one end to the other. The upper end of the tank is designed to be the inlet end thereof, while the lowerend of the tank is thev outlet end thereof. The `inlet to the tank is through the top of the tank so thatsnow and ice may be placed therein. Most of the tank is cov` ered and the outlet end of the tank is provided with a stack or vent through which the steam and Water vapor together with the heated air issuing from the heating elements is dispelled.
These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification and claims.
,In the drawing forming a part of my specification:
Figure 1 is a top plan view of my snow melting device.
Figure 2 is a sectional View through my snow melting device longitudinally of its axis.
Figure 3 is a transverse section through the body of the snow melting device, the position of the section being indicated by the line 3-3 of Figure 2.
The snow removing device A comprises a tank B which preferably rests upon a supporting frame C, which in turn is mounted upon wheels or other suitable means, so that the tank maybe which in the form illustrated, comprises a series of parallel pipes I6 having perforations therein to act as gas burners. Suitable openings I1 are formed in the bottom Wall I5 to admit air between the bottom walls I4 and I5, and to support combustion of gas flowing through the gas pipes I6.
The gas pipes I6 are illustrated as connected by a supply manifold I9, which is connected by a pipe line to any one of a series of gas supply tanks 2|. A valve 22 may control the ow of gas to the gas pipes I6, which when ignited heat the false bottom I4 to a high temperature.
A baille 23 extends transversely or substantially parallel to the end walls -I2 and I3 from the side wall I0 to a point spaced from the side wall I I allowing a passage 24 through which liquid may flow. A baille 25 `extends substantially parallel to the end Walls I2 and I3 from the side wall I I to a point spaced from the side Wall I0 to provide a passage 26 through which liquid may flow. An'additional baille 21 extends substantially parallel to the previous baille from the side wall I0 to a point spaced from the side wall Il to provide a passage 29 through which liquid may flow.A Thus as the liquid travels down the inclined bottomk I4, it must flow from one side of the side of the tank B to the other so that the distance of travel of the flow of liquid is greatly increased.
Extending upwardly from the false bottom I4, I provide a series of pipes or tubes 3U which are open at both ends and which preferably terminate short of the upper extremity of the side and end walls of the tank B. ,These pipes 30 are positioned between the baffles 23 and 25, between the baffles 25 and 21, and Ithe end wall I3. As the liquid ows over the surface-of the false bottom I4 it comes in contact with these pipes or tubes 3U, which arev formed of metal in preferred form, and which are heated by the connection With thefalse bottom I4` and also by the passage of heated air passing therethrough.
A series of inclined pipes or tubes 3| is positioned between the end wall I2 and the baffle 23. The tubes 3| are open at both ends and extend through the false bottom I4 and through the baffle 23 to conduct heated air from the compartment 32 between the bottom I5 and the false bottom I4 into the body of the tank to prevent Waste of the heated air. l
A top 33 extends over the tank B. The top 33 extends between the side Walls I0 and II and from the baille 23 to the end wall I3. The baie 23 extends to the full height of the side walls I0 and II and forms a closure for the tank, except through the passage 24. The baiiles 25 and 21 terminate short of the cover or top 33 permitting air to ow above these bailies toward the end I3 of the tank.
The top 33 preferably slopes upwardly from the bale 23 toward the end wall I3 and a stack or vent 34 is positioned in the top 33 near the end wall I3.
The frame C is illustrated as supported by springs 35 and l36 connecting the frame vlC to the axles 31 and 39 of the wheels 40. Thus the device A may be moved about from place to place.
In operation, the gas supplied from one or more of the tanks 2I is fed through the valve 22 and the manifold pipe I9 to the gas pipes I6 and the gas issuing from these pipes is ignited. The false bottom I4 is heated to a high temperature and the gas or air heated by the flame passes through the tubes 30 and 3I heating these pipes and with the surrounding air.
maintaining the interior of the tank B at a higher temperature.
Snow and ice are shoveled into the tank I0 between the side walls I0 and II, the end wall I2 and the baiile 23. This snow and ice falls upon the false bottom I4 and on the pipes 3I causing most of the snow and ice to melt and the remainder thereof, to be carried by the water through the passage 24 to the surface between the bailles 23 and 25. f
Passage of the water over the false bottom and in contact with the pipes 30 tends to vaporize the water and change the same into steam. This steam and Water vapor is expelled together with the hot air and gas through the stack 34 mingling Thus all of the ice and snow is disposed o'f before the 4same is expelled from the tank B.
The tank B may be insulated in any suitable manner if it is so desired and the number and position of the pipes 30 may be changed if it is so desired. l r
'I'he means of placing the snow and ice into the tank is not important as the snow and ice may be shoveled into the tank manually 'or may be fed into the same by a mechanical elevatoror conveyer belt designed for this purpose.
In accordance with the patent statutes I have described the principles of construction and oper-v ation of my snow melting device, and while I have endeavored to set forth the bestl embodiments thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
