(01. tar-92) 2 Claims.
My invention is a rotor of an improved, type for ice shaving machines. I
The principal object of the invention is to provide a rotor wherein heat insulating material is packed to reduce to a minimum the melting of the ice coming in contact therewith, and wherein the ice collecting pockets are of such size, shape and location as to reduce melting of the ice by providing quick discharge of the shaved ice from the rotor pockets into the discharge chute.
Another object of the invention is to provide access to the interior of the rotor drum for packing of the heat insulating material, such access means, however, excluding the entry of water or ice into the heat insulation during normal use and operation of the device.
Still another object is to provide a rotor of the hollow drum type which is internally strengthened by webbing extending outwardly from the hub.
A further object of the invention is to provide means for breaking up ice jams in the ice approaching the shaving rotor to insure continuous feeding of ice thereto.
Other objects and advantages of my invention will become apparent. in the discussion of the drawing wherein:
Figure 1 is a cut-away view of the ice shaving rotor mounted in a machine.
Fig. 2 is a plan view of the rotor.
Fig. 3 is a side elevation of the rotor.
Figure 1 shows an ice shaving machine of typical design having an ice hopper A with heat insulating material B in its walls. The hopper A is supported on a frame C which supports a motor M having a shaft S. Near the bottom of the hopper A is a chute D adapted to dispense the ice as it is shaved. The present invention, however, is not concerned with the structur of the machine, but relates entirely to the rotor l shown in all three figures of the drawing.
The rotor l comprises a cylindrical outer surface la, an upper surface lb, and a lower surface lc so that the general contour is that of a closed cylindrical drum. Through the center of the rotor I is a hub ld having a bore le to receive th motor shaft S. Radial webs If are pro vided to strengthen the assembly. An annular downwardly extending flange lg is attached to the lower rotor surface lo, the latter being open within the flange lg to allow access to the interior of the rotor for the purpose of packing the interior with heat insulating material 2, Figure 3.
Around the cylindrical outer surface Id of the rotor l are a plurality of outwardly opening pockets lh, the leading edges l m of the pockets lh being substantially radial while the trailing dges l'o are angled so as to assist centrifugal force to throw the shaved ice outwardly. The upper surface lb, near the leading edge lm of each pocket in is slotted as at lp and also carries a lug lq inclined upwardly in the direction of rotation of the rotor, Fig. 3. The lugs lq are for the purpose of supporting in operative position the ice shaving blades 3 held in place on the lugs by screws 4.
On the top surface lb of the rotor l is a vertically disposed eccentrically located cutter ls adapted to break up ice jams above the rotor l to assist the smooth and continuous feeding of ice to the blades 3.
In operation, the motor M turns the rotor l on the shaft S and the ice is fed downwardly to contact the upper surface lb of the rotor. The blades 3 extend above the surface lb and shave the ice, depositing the shavings into the pockets lh where the shavings are thrown outwardly by centrifugal force into the chute D for delivery. Note that the blades 3 and the lugs l q are cut diagonally downwardly on their leading edges to eliminate resistance to the downward flow of ice, and that the trailing surfaces lo of the pockets lh are angled to eliminate the collecting of ice which might remain and melt after th shaving operation is completed. The size of the pockets is purposely held to a minimum to decrease the amount of rotor area contacted by the shaved ice and to hold the shavings near the outer periphery of the rotor to insure the maximum effect of centrifugal force thereon. The heat insulating material 2 tends to isolate the heat of the motor from the ice in the hopper A and to augment the effect of the insulation B.
I do not limit my invention to the exact form shown in the drawing, for obviously changes may be made within the scope of the claims.
I claim:
1. In an ice shaving machin having a cylindrical ice hopper and having a chute extending outwardly and downwardly from the side of the hopper near the bottom and having power driven shaft disposed axially of the hopper and extending upwardly thereinto; an ice shaving rotor comprising a hollow cylindrical drum closed at each end and having a bore through its center for mounting the drum on said shaft opposite the chute; a plurality of outwardly opening pockets recessed in the outer cylindrical surface and uniformly spaced therearound, the upper end of the drum being substantially radially slotted above each pocket; an ice shaving blade extending upwardly through each slot disposed at an inclined angle in the direction of rotation; heat insulating material packed into and filling said drum; a concentric annular flange extending downwardly from the lower end of the drum, the drum being open within the flange to allow access for packing the drum with heat insulating material.
2. In an ice shaving machine having a cylindrical ice hopper and having a chute extending outwardly and downwardly from the sid of the hopper near the bottom, and having a power driven shaft disposed axially of the hopper and extending upwardly thereinto; an ice shaving rotor comprising a hollow cylindrical drum closed at each end and having a bore through its center for mounting the drum on said shaft opposite the chute; a plurality of outwardly opening pockets recessed in the outer cylindrical surface and uniformly spaced therearound, the upper end of the drum being substantially radially slotted above the pockets at the leading edge of each pocket,
4 and the trailing face of each pocket being angled so as to throw the shaved ice outwardly; an ice shaving blade extending upwardly through each slot disposed at an inclined angle in the direction of rotation; heat insulating material packed into and filling said drum; a concentric annular flange extending downwardly from the lower end of the drum, the drum being open within the flange to allow access for packing the drum with heat insulating material.
