or support for the blade 2. The blade of the conveyer is formed by a plurality of pipes 3 radially disposed upon the shaft l and communicating with the duct or bore 4 of the tubular shaft. In fact, the conveyerblade is preferably formed out of a plurality of pipes 3 arranged in helical formation, each pipe or tube being' closed at its outer vend 5 and provided with openings 6 for the egress of steam or the heated medium. As shown in Fig. 1 the shaft 1 is closed at one end, as at Ga, and has communication, at the other end 7 with a duct 8 for steam or other heating medium. The heating medium which is introduced into the duct or bore 4 finds its way into the pipes 3 and out through the openings 6. The passage of the heating medium heats the conveyer, the degree of heat depending upon the temperature of the heating' medium, that is to say, the conveyer can be kept warm or rendered very hot. F or melting snow, for instance, the snow would be introduced into the casing 9, at 10 for instance (the conve-yer being rotated as per the arrow 11) and delivered to the outlet 12. During the passage from the inlet to the outlet the snow would be melted by the heat of the steam (for instance) passing through the conveyer and out through the openings 6. The conveyer would not only drive the snow from the in- ,let to the outlet, but it would also mix it. To increase the mixing or stirring` effect of the conveyor the outer end of each tubular element 3 can be bent or hooked as at 3a, Fig. 5. My improved conveyer is not limited to he melting of snow, but can be used for treating' grains, or mixing purposes where heat is used.
Instead of forming the blade 2 out of a plurality of tubular elements, I may form the said blade out of two plates 13 and 14 spaced to form a channel (Figs. 6 the said plates being' closed as at 15 a duct 16 and secured to the tubular shaft 1, as at 17. As in the first described form, the plates 13 and 14 are provided with openings 18 for a similar purpose.

To all whom t may concern Be it known that I, GEORGE SoHULnR, a citizen of the United States of America, re siding at Woodside, Queens county, State of New York, have invented certain new and useful Improvements in Conveyors, of which the following is a full, clear, and exact description.
This invention relates in conveyers, the object device of this character more particularly adapted for use in connection with material to be heated, kept warm or melted during the transportation thereof from one point to another. For instance in combination with a snow-gathering machine, my improved conveyer is adapted to move the gathered snow from the hopper to the outlet and at the same time melt or assist in the melting of the snow during the moving thereof. To carry out the object of my invention, I design the conveyor in such manner as to adapt it to be heated during its operation.
I will now proceed to describe my invention in detail, the essential features of which will be summarized in the appended claims, reference being had to the accompanying drawing, forming part hereof, wherein z* Figure 1 is a side elevation of my improved conveyer; Fig. 2 is an enlarged crosssectional view thereof, the section being taken on a line 2`2 in Fig. 1; Figs. 3 and 4 are detail sectional views of the conveyersupport.- Fig. 5 is a detail view of a modified form of conveyer-blade tube; Fig. 6 is a side elevation of a modified form of my improvement; and Fig. 7 is an enlarged crosssectional view, the section being taken on a line 7 7 in Fig. 6.
As has been stated, my improvement is intended to be utilized for the purpose of heating' or melting or keeping heated any material adapted for such treatment during the passage of the material from one point to another. To carry out my invention, I construct the conveyer in the form of a pipe or duct 1 which constitutes a tubular shaft to an improvement being to provide a Y. VLetters Patent, is:
