SNOW-COMPRES SING MACHINE.
SPECIFICATION forming part of Letters Patent No. 698,566, dated April 29, 1902.
Application filed February 23, 1901. Serial No. 48,491. (No model.)
T0 at whom it may concern:
Be it known that I, REUBEN SHIRREFFS, a
citizen of the United States, residing at Rich-- mond, in the county of Henrico and State of Virginia, have invented new and useful Improvements in Snow-Compressing Machines, of which the following is a specification.
My invention relates to improvements in snow-compressing machines, and has for its objects, first, to provide a novel compressing mechanism and mode of operation, and, secondly, to provide in connection therewith a breaking-up device.
T0 the ends stated my invention results in a machine embodying the features and mode of operation hereinafter described, and illustrated in the drawings.
That which I regard as new will be set forth" away to show the interior construction; and
t Fig. 2, a transverse section.
In the said drawings the reference-numeral 1 indicates a suitable frame, in which axles 2, carrying ground or traveling wheels 3, are supported. I have shown this frame as of skeleton formation in the drawings, although it may be of any suitable formation and material. Supported by this frame-=for instance, in the manner 4, shown at the left of Fig. 1 of the drawings-are stationary thrustresisting elements 5, which conform to the shape of the cylindrical carrier hereinafter referred to. These thrust-resisting elements are preferably in the form of hollow plates; into which steam or other heat may be introduced from any suitable source, (not shown,) an inlet, such as 6, and an outlet, as 7, being provided therefor, as illustrated in the drawings. The said elements 5'support in a suitable manner platforms 8, to which are secured guides or deflectors 9 for directing the snow into the path of the snow gathering and carrying apparatus, and to said platforms are secured snow-levelers 10 for the purpose of partially packing the snow before it reaches such snow gathering and carrying mechanism.
The snow gathering and carrying arrangement consists of a drum-like structure rotating upon a shaft S, and comprises circular side plates 11, between which, at their peripheries, extend partitions 12, forming a series of peripheral snow gathering and carry- :ing chambers 13, the walls of which are mounted on cross-arms 15, which are adapted to play within slots 16 provided therefor in the side plates 11 of the drum-like structure, the ends of said cross-arms projecting outside of the side plates 11, and preferably provided with antifriction-rolls 15, entering cam-races 17, with which the frame 1 is provided, whereby during the rotation of the drum the said plungers are forced outwardly in their respective chambers 13, compressing or densifying the snow contained therein while said chambers are passing in front of the thrust resisting or receiving elements 5, as graphically pictured at the right hand of Fig. 1 of the drawings. The form and arrangement of the cam-races 17 may be varied, as may be desired; but I prefer to use a form such as shown, so that the initial action of the plungers shall be rapid, or, in other words, the stroke comparatively long, as the snow contained in the chambers prior to the action of the plungers is comparatively loose and may be compressed or densified to a considerable extent by the initial stroke of the plungers. The eccentricity of the cam-races decreases after the initial stroke has been com pleted and as the compression or densification of the snow increases, ofi'ering greater resistance. Furthermore, the cam-races are preferably formed with an abrupt eccentricity, as shown at 17 at the point in the travel of the plungers where the snow has been compressed or densified to the maximum capac- Ice ity of the machine, so that the plunger carrying a compressed or densified'qua'ntity of snow is thrown quickly outward to its limit, presenting the densified mass to the action of the breaking-up or disintegrating device, which will now be described. This device in the form in the drawingsconsists of ad-' justable spaced-apart rings 18, mounted upon a shaft 19, supported in'extensions 1 of the frame 1 and provided with a series of teeth with spikes or sharp points 20, which act to break up or disintegrate the compressed masses of snow as the same are presented thereto in the operation of the machine. This breaking-up device or disintegrator is a desirable auxiliary of the machine, whereby the compressed snow is delivered in small dense quantities,which maybe handled with greater facility than a single large mass of the densified or compacted snow. The disintegrated or broken-up densified or compacted snow is delivered onto shelves or chutes 21, which may deliver the same at any suitable point,as at the side of the machine or into accompanying depositories, by which it may be carried away.
The snow gathering and carrying arrangement is journaled in the frame 1 by means of an axle S and may be driven or rotated in any suitable manner. In the example shown in the drawings it is driven by an electric motor, (shown conventionally at 23,) which drives a shaft 24, carrying a pinion 25, in mesh with a bevel-wheel 26, carried by the axle of the drum-like structure.
The disintegrator or breaking-up device, as shown, rotates at a greater surface speed than that of the snow gathering and carrying mechanism, as obviouslyit must in the illustrated example, in order to disintegrate or break up the snow. In addition to its breaking-up function the disintegrator throws the snow out upon the chutes 21. It maybe differently arranged and may be driven in any suitable manner, a convenient means being that illustrated in the drawings, wherein it is rotated by means of a crossed belt from the shaft S.
The machine illustrated in the drawings is arranged with similar snow guides and levelers at each end, and the two thrust resisting or receiving elements are provided, so that the machine will work equally well when moving in one or other direction, as will be apparent; but I do not restrict my invention to a double-header machine. 7
Many changes in construction and arrangement may be made within the scope of the following claims without departing from my in vention.
The operation of a machine embodying my invention will be readily understood from the drawings and description.
When the machine is moving in the direction indicated by the arrows, Fig. 1, the snow is guided into the path of the gathering and carrying arrangement, being packed somewhat by the leveler, and is gathered in by the rotating chambers and carried therein across the face of the thrust resisting or receiving element, during which the plungers act in the manner described to compress or density the snow. When a gentle heat is imparted to the thrust-resisting plate, the contacting snow is softened, enabling it to slip easily. After compression the snow is subjected to the supplementary action of the disintegrator, which breaks or tears it into small dense lumps or masses and throws it out onto the shelves or chutes, which drop it, as convenience or conditions dictate.
By properly regulating the speed of the m0- tor 23 the machine may be controlled so thatthe gathering-chambers shall take in a full measure or only a partial charge of snow, according to the lightness or heaviness of the fall of snow. It may be desirable to have the snow delivered by the machines of a given uniform density, in which case if the snow is light the revolution of the snow-gathering chambers will be made slow and the chambers takein a full charge. On the other hand, if the snow be of a heavy nature the speed of revolution maybe suitably increased, so that a partial charge only will be taken by said chambers.
