WITNESSES INVENTOR- UNITED STATES PATENT/OFFICE,
canwanriazonn EVANS, an, or rrrrseune, rnnNsYLva-nr 1 T(i 'qlt'whom"it may concern: fi'e tnown that I, GADWALLADER EvANs, J' a itiz'en of the Unitedfitates, and resis dent-, of l?ittsburg, Allegheny county, Penn- 5 syl a 'a, "have ;invented a. l l wf'and useful Math (l'iof 'Snow Disposal, 0 f, which the fol-- lowing is aspec'ification, a W invention rel tes principally to a rhethodpfremoving snow from the streets of 'la'i'gefcitie'sto avoid interference with traffic thereon.
I have discovered that freshly fallensnow may be reduced by agitation alone, to a sufliciently fluid condition to be forced through 5 a pipe by any convenient means as for instance fluid pressure used directly such as air, steam, or water or by any suitable mechanical device such as a centrifugal pump, and that snow which has been subjected to the compressive actionof street traflic, even when it has reached a condition bordering on the hardness of ice, or when mixed with actual ice, may bereduced to a similar condition by agitatiomand the addition of a slight amount of water. It is not necessary in either case to reduce the mixture to a real fluid, which will flow of its own accord, nor if ice be present is it necessary to reducethe ice to a finely subdivided state. Lumps of ice of several inches diameter may be car-' ried when in a semi-fluid slush, such as is used by my improved method.
The removal of snow in American cities costs a vast amount of money annually,'andthe present process takes further toll on the health and lives of the laborers employed, as the work must of necessity be done in. in- "clement weather and under conditions inimical to-health.
40 The present method of removing snow from streets is very crude, and is accomlished usually by men with shovels, who oad the snow into wagons, from whence it is hauled tothe nearest sewer opening, and
- discharged therein. This process is necessarily slow, and consequently expensive, as a large force of men and teams must be employed to cover any considerable'area, it being usually nece'ssaryto completely'remove the snow within a few hours time. I am .aware that various methods have been sugested to facilitate the handling of this probi em. For instance, it hasbeen proposed-by several inventorsto melt the snow by the METHOD or snow nisrosA'L. H

By my improved method the snow and ice mixed therewith may be expeditiousl removed at small cost, and at great spee and conveyed directly to the nearest sewer without being a second time in contact with the street.
My im roved method is independent of any speclfic a paratus, and may be performed manua but greater s eed may. be. obtained by the use of suitabe apparatussur-h-as-will now be described. a
-The truck A, mounted on the wheels B, carries a hopper O, to which the snow may.
be delivered manually, or by suitable mechanism. The hopper C discharges into-an agitator D, whose principal function is to reduce the fine snow to slush by agitation thereof,-and to break up masses of'caked ice or snow, into lumps small enough to enter the pump F. If necessary water may be en plied to agitator D, through ipe E. The pJump F, receives the mixture rom agitator and forces the same under pressure through the large hose H, to the nearest seweiz. Pump F, and agitator D, are driven by a motor G, herein represented as a gas engine. The hose H maybe of any desired length, as for instance equal .to one or two city blocks, and the truck may therefore move forward continuously toward the snow to be removed, at the same timebeing all times. in direct connection with the sewer.
