To all 'whom t may concern.'

Be it known that l, 'WILLIAM T. EnronsoN, a citizen 'of the United States, and a resident of New Yorlr cit in the county of New York and State o New York, have invented certain new and useful improvements in Snow-Melters, of which the iollowing is a specification.

My invention relates to snow melting device and has for its particular object a device whereby the snow is subjected to the direct heater" combustion in a combustion chamber itself.

Another object ol:q my invention is a device in which the snow is introduced into and melted within a combustion chamber practically free from loss ci heat hy radiation or direct exit.

Another object of my invention is a power driven machine in which the power may loe employed either for the propulsion oi" the machine or for the operation of the snow handling mechanism.

Another object or" my invention is a device in which the passage 'of the snow through the combustion chamber may be so regulated as to insure complete conversion into water.

Another object oi my invention is a device in which the snow is automatically lifted and deposited upon a movable distributing member for subjection to heat.

Another object of my invention is a device in which the separation of stones, wood, etc., from the melted snow may be readily accomplished.

Other objects will be in part olovious and in part pointed out hereinafter.

The invention accordingly consists in the :Features of construction, Vcombination of elements and arrangement oi parts which will he exemplied in the construction hereinafter set forth, and the scope or" the application which will be indicated in the following claims.

it is generally admitted that the lmoet edective work of disposing oi snow is hy an ecient melting thereof and numerous methods have been proposed for the accomplishment oi this result.

lt has been suggested that the snow he melted by means of hot air, hot water, steam, lissage over heated surfaces, andothersimiar methods but their practicability has been of little value as in none of the devices has use been made of the double heat units of the combustible material. Loss of heat due to its absorption bythe intermediary substances, to radiation, to the handling of the snow or to other causes, has proven them to he of no practical value, on account of the expense incident to their use or to their ineectiveness upon the snow.

it is evident that the most edective and eoient method of melting snow is one in which the snow is subjected to the direct heat of combustion and in which practically all of the heat units are utilized for the desired purpose, without loss due to radiation and in which all ofthe heat is absorbed hy the snow for its conversion into water.

My device overcomes all of the objections incident to the prior pro osed methods and presents a method where y the snow is continuously and automatically handled with a minimum of labor and expense, in which it is directly subjected to the intense heat of a combustion under pressure and in which the melted snow in the form of water is practically separated from the impurities not adected by the heat.

ln'the accompanying drawings in which is shown one or various possible embodiments of my invention similar reference characters reier to similar parts throughout the diderent views of the drawings.

ln the accompanying drawings:

Figure l illustrates a longitudinal crosssection of the device.

Fi 2 illustrates a cross-section through the line Qr-Q or Fig. l.

Fi 3 illustrates a cross-section through the line 8-3 oit Fig. 1l.

Fig. 4 illustrates a top view partially broken away to show the heating device.

Fig. 5 is an enlarged view vof the igniting means shown in Fig. 4. l

Fig. 6 is a side plan view showing the means of connecting the power from the motor to the mechanically moving parts of the device.

Fig. 7 is a view through the line 7 7? of he particular form of my device as shown in the accompanying drawings comprises a truck composed of the two sections 8 and 9 pivotally connected at l() and mounted upon wheels lll-11', 12-12,

13-13. The truck section 8 carries a cylindrical snow melting chamber 14 which is entirely inclosed except at the points indicated in the further description. This snow melting chamber 14 is made preferably of iron or steel and covered with asbestos or other non-conductor of heat 15. Within the snow melting chamber 14 is a movable endless linked belt 16 capable of moving lengthwise of the chamber and composed of a series of linked tray shaped receptacles 17-17 each comprised oi a perforated bottom 18, side walls 19-19 and a rear wall 20, the top and forward end of,

the trays being open. These tray members are so formed and situated with respect to each other that during the movement of the linked series the upper row will form a se ries of receptacles for receiving and carrying the snow, the unmelted snow, dirt, stones etc. being dropped from the trays through their open ends as they pass over the hexagonal wheel 21. Movement is imparted to the series o1 linked trays forming the movable belt by means of the revolving hexagonal wheel 21 which in turn receives its power from a motor source explained later. The rearward end of the linked belt is supported by and revoluble with the hexagonal wheel 22. The wheel 21 is supported by and revoluble with the shaft 23 carrying a fixed attached spur wheel 25 exterior to the snow melting chamber 14. The wheel 22 is similarly supported. ln order that the water resulting from the snow melted in the upper portion of the linked snow carrying/belt shall not fall through the perforations thereof upon the lower portion of the belt and cool the latter unnecessarily, an angular bevel plate 26 is introduced between the upper and lower portions of the linked belt in such a manner that the water will be diverted from contact with the lower series of the linked belt. 7Nithin the snow melting chamber 14 is a series of properly disposed burners 27-27 capable of producing intense heat from vaporized combustible liquids under pressure. rlhese burners are so situated as to impinge their heat upon the snow carrying belt 16 and especially upon the snow carried therein, the object being to melt the snow in the upper series of linked trays during its passage through the chamber 14. The size, number and position of these burners may be varied but in the accompanying drawings they form three series of burners longitudinal of the chamber 14 above the snow melting belt 16 and three series below said belt. The means of operation of these burners is as follows: A tank 28 is devised to carry a vaporizable inflammable liquid, such as gasolene, kerosene, etc. The top of the' tank 28 is connected by means of the pipe 29 with a compression pump 30, the meansof operation of which will be explained later.

:incassa The bottom of the tank 28 is connected by means of the pipe 31 with the two sets of burners, one above and one below the snow melting belt. As the means of connection is the same in the two sets, it will be suiicient to explain it as shown with one set, as illustrated in Figs. 4 and 5. The pipe 81 connects with the distributing pipe 32 which in turn is branched into a series of pipes entering the forward ends 3-3--33 and the rearward ends 34--34 of the combustion tubes 35-35 having perforations 36-36 through which the gas escapes and at which it is ignited. As Fig. 4 illustrates the upper se- -ries of burners, the perforations 36-36 are in the under side of the tubes 35-35, while the perforations in the lower series of burners are on the upper sides of the combustion tubes. The two series are connected by the pipe 37, valves 38 and 39, to allow the discontinuance of the liquid into the several series. ln order to allow of the vaporizing and igniting of the liquid a pipe 40- (see Fig. 5) tted with a valve 41 is connected with the tube 42 comprising a chamber 43 connected by means of the perforations 44-44 with a layer of asbestos or similar material 45. ln operation the iniiammable liquid from the tank 28 is forced by means orn the pipe 46, is vaporized, passes through rations 36--36 and is ignited.

.i-orizontal wheel is idxedly ae axle 47 revoluble within ber fupported by the side wall ci@ combusti chamber 14. Upon the outward end of the shaft 47 is tixedly attached a toothed sprocket wheel 50 around which passes a chain belt 51, the chain belt also passing around a sprocket wheel 52 situated to the rearward of and external to the combustion chamber 14. The sprocket wheel 52 carries a linked bucket lift belt 53 carried around a sprocket wheel 54 revoluble within the bearing 55. This entire snow hoisting mechanism is surrounded by a. casing 56 extending upwardly and then diagonally downwardly at 57 to within the combustion chamber 14, the object of the casing being to prevent the escape of the heated air from the chamber 14 and to act as a guiding means for the snow which is thus deposited through the open end 58 of the casing 56-57 upon the linked tray belt 16. A similar hoisting means is similarly attached to the other end 49 of the-shaft 47, thus providing two snow hoisting means for depositing snow upon the linked` tray belt. The power mechanism comprises an ordinary suitable motor, not

shown, whereby a rotation of the shaft 59 f is accomplished through the bevel ars 60--61, and an ordinary power shitting lever 62 and mechanism 63 allows of the shifting of power from the spur gear 64 with the consequent rotation of the chain drive 65 and the rotation of the wheel 12 and resultant motion of the entire device, to the spur gear 66 which operates the pump 30 and to the bevel gears 67 and 68. The bevel gear 68 is iixedly attached to the end of the shaft 69 revoluble in the bearings Z0-71. The worm gear 72 is slidably attached to the shaft 69, the worm thereof operating within the corrugations of the spur gear 25. rlhe worm gear 72 is maintained slidably by means of a projection or ke fixedly attached to the gear 72 and mova le within the longitudinal recess 73 of the shaft 69. Two universal joints Zi-Z5 in the shaft 69 allow ci the revolution of the shaft when the two truck sections 8 and 9 are not in direct line due to their partial revolution upon the pivotal member l0. Suitable doors 767778 are arranged for gaining access to the combustion chamber la, and pipes 79-80 allow of the constant removal ci the water resulting from the melting of the snow.

ln operation the device is moved to its place oi operation by means of the motor operating upon the spur gear 64C, thus moving the vehicle by means of the chain drive 65. When the device has reached the place oi operation the lever 62 is shifted so as to disconnect the motor powerand set in operation the pump, snow melting chain and snow hoisting device. The vaporized combustible gases are then ignited as described above and when the interior of the combustion chamber lll has reached a Sudiciently high temperature the snow is shoveled upon the bottom trays of the snow hoisting apparatus, which raises the snow and deposits it upon the rearward end of the snow melting chain. As this snow melting chain moves forwardly the intense heat of the burning gases melts the snow and allows the water to fall down through the perforated bottoms of the trays upon the 1nadie board 26 into the bottom of the combustion chamber 14 where it runs od through the openings Z9-80. `Unmelted snow, dirt, stones, etc., are carried along by the snow melting trays and dropped oid at the forward end of the combustion chamber 14 and withdrawn when necessary through the door 7 8. l
