To form the blade seat 21 the cutter head is illustrated as provided with radial ribs 40 adjacent slots 18 to 20. The knife or blade seat 21 provided on the rearward wall of slot 18 supports a knife or blade 22 having a cutting portion 23 extending from the periphery of the cutter head radially inward for substantially'one-third of the radiusof the cutter head. The cutting portion 23 in use is adapted to sweep over an annular area bounded by circumferential lines, the larger of which hasa radius equal to that of the cutter head and the smaller of which has a radius equal to substantially two-thirds of the radius of-the cutterhead.

shown in Fig. 3.
It will thus be noted, with the screws 30 and move the blades so that the knife edges of the cutting portions 23, 25 and 2'7 are positioned further from the working face 28 of the cutter head. The working face 28 is divided into three sectors by the slots 18 to 20 and each of these sectors is cut away on small arcs 32 adjacent the centerv of the cutter head, to enable a more ready. flow of ice shavings through slots The cutter head together with the knives 22, 24 and 26 mounted thereon provide a cutting unit which in practice shaves ice with great rapidity.
The ice shaver is provided with a plunger 33 having a shank 34 formed thereon, which shank terminates in a'yoke 35 that has its legs pivotally mounted upon the casing 2 as by bolts 36. Shank 34 is formed to provide a tapered aperture 37 for receiving a plunger handle 38 to be used in operating'the plunger 33. A rubber stop 39 is provided upon the plunger handle 38 for cushioning the movement of this handle when the same strikes the rim of easing 2, as especially illustrated in Fig.1. Plunger 33 is provided on its inner surface with an arcuate, inwardly directed flange 42 which cooperates with the inner wall of easing 3 2 to guide the ice blocks 43 onto the working face 28 of the cutter head as the plunger is moved The inner surface of plunger 33 is also provided with a plurality of pointed prongs 44 which grip the ice and aid in directing the same toward the working face 28 of the cutter head.
I The ice shaver is illustrated in Figs. 1 and 2 as provided with removable legs 45 which are secured at their upper ends to the casing 2 by screws 46. With the legs45 attached to the easing 2, the machine may be used as illustrated in Fig. 1, wherein the pan 9 is employed for collecting the ice shavings, or, if the base 5 is removed from casing 2, a larger container, such as a barrel,
may be placed below the casing 2 for collecting the ice shavings discharged from the machine. If the legs'45 are removed from the casing 2, the machine may be placed upon a table or other support for use, as illustrated in Fig. 4.
In operation, to put ice into the machine, the plunger handle 38 is turned outwardly sothat the plunger 33 moves to its outermost position Blocks of ice 43' are then inserted through opening 3 of the casing 2 and allowed to collect in'the bottom of the casing. The plunger is now moved inwardly of the casing 2, causing the inner surface thereof to contact with and grip the ice blocks 43 and to press these blockstowar'd the working face 28 of the cutter head. The operator now turns the hand wheel 16 to cause the cutter unit to revolve in the direction of the arrows indicated in Figs. 4, 5 and 6,
thereby causing the cutting portions 23, 25 and 27 of the outer, middle and inner knives to cut the ice pressed against the working face 28. The cutter depth at which the knives are set will determine the size of the ice shavings produced, which shavings after being cut from the ice blocks fall through the slots 18 to 20 and through cutter head and facilitates the manual operating of the machine with a minimum of effort. The use of three knives, each having cutting portions sweeping over independent cutting areas results in each one of these cutting portions operating at a maximum efficiency to effect a full depth of cut as measured by the extent of projection of the respective cutting portion beyond the working face 28 of the cutter head. Thus, each cutting portion in sweeping over its independent area is unaffected by the action of the remaining cutting portions, so that uniform ice shavings are obtained.
Each of the knives will cut at all times to the depth determined by the setting of the knife, regardless of the depth setting of the other two knives. If it is desired to produce'a variety of ice shavings or ice shavings of varying thickness, the respective knives may be set at varying cutting depths. In use, it is found that the novel ice shaver of this invention has a greatly increased capacity over the old type of ice shavers, wherein the cutting blades swept over common cutting areas and wherein constant interference of one knife blade with another resulted in one blade doing practically all of the cutting, whereas the remaining blade or blades merely followed along without exerting any cutting action, but
nevertheless tending to throw the ice away from the cutting edge of the working blade, thereby reducing the output of the machine.
As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
What is claimed is:- v
1. In an ice shaver, a cutting unit comprising a cutter head having a forward circular working face, said cutter head being provided with three relatively wide radial slots therein disposed in Y formation, the point of juncture of said slots being at the center of said working face, said cutter head being cut away along small arcs adjoining the point of juncture of said slots in order to facilitate the flow of ice shavings through said radial slots, three knife blades, each of said knife blades being adjustab-ly attached to a wall of a respective one of said radial slots, each of said of said cutter head, whereby the cutting portions of each of said knives sweeps. over an annular cutting area in use that is different from the annular cutting areas of the remaining cutting portions, so that the ice shavings produced by each cutting portion are of uniform quality owing to the independent cutting action of each cutting portion. p
2. An ice shaver comprising a casing having an ice receiving aperture at its top and an ice shaving discharge mouth at its bottom, a rotary cutting unit positioned within said casing adjacent said discharge mouth for shaving ice deposited within said casing and for'passing the shavings to said discharge mouth, said cutting unit being of disc shape and having three radial slots'arranged in Y formation therein, each of said slots having a knife mounted on the side wall thereof, said cutting unit being cut away along small arcs adjoining the juncture of said slots in order to facilitate the flow of ice shavings through said radial slots, said knives having cutting portions projecting forwardly of the front face of said cutting unit, the cutting portion of each of said knives having a length substantially equal to onethird of the length of one of said slots and being disposed at a radial distance from the center of said cutting unit that is unequal to the radial distances of the remaining cutting portions, whereby each of said cutting portions sweeps over an independent annular cutting area in use, a plunger pivotally mounted at the upper portion of said casing, and a handle secured to said plunger for use in moving said plunger into said casing for pressing ice toward said cutting unit, said plunger having pointed projections and an arcuate flange on the inner surface thereof for gripping the ice and for cooperating with the wall of said casing to urge ice into operative engagement with the knives of said cutting unit, said arouate flange and the wall of said casing conforming to the perimeter of the said cutting unit, thereby preventing the discharge of unshaven ice from said ice shaver.
