UNITED STATES FRED L. SHAW AND DAVID DUMMER, OF STEUBENVILLE, OHIO.

ICE-SHAV'ING MACHINE.

Application filed November 22, 1922. Serial No. 602,633.

T 0 all whom it may concern Be it known that we, Fnno L. SHAW, and DAVID DUMMER, citizens of the United States of America, and residents of Steuben- Ville, county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Ice-Shaving Machines, of which the following is a specification.

This invention relates specifically to iceshaving apparatus, and it has for its primary object to provide a mechanical ice shaver which is strong and durable in con struction and which is comparatively simple and inexpensive to construct.

A further object is to provide an iceshaving machine which may be made either in large sizes capable of furnishing large quantities of ice in shaved form or in a small size designed for household use.

A still further object is to provide shaving blades which may be conveniently adjusted to cut to any desired depth and which may be readily removed for sharpening.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which Figure 1 is: a substantially central vertical section of the invention;

Figure 2 is a top plan view of the bladecarrying bevel gear;

Figure 3 is a horizontal section of the ice chest; and- Figure 4 is an enlarged detail section on line 44, Fig. 2.

Referring to said drawings, 1 indicates a casing having its upper end cylindrical in form and having its lower end portion 1 contracted into spout shape. Rigidly mounted upon the interior walls of the casing at appropriate points are the arms 2 of a spider which stationarily supports a centrally disposed upright pin or spindle 3. Mounted for rotation upon said spindle is a sleeve-bearing 4: carried centrally upon the under side of a large horizontally disposed bevel gear 5 which has a diameter approximating that of the interior of the upper end of the casing 1, an internal annular ledge 6 formed on said casing being located in underlying relation to the peripheral edge of said bevel gear, as shown.

Disposed in driving relation to said bevel gear 5 is a bevel pinion 7 carried by the inner end of a horizontal shaft 8 which is journaled adjacent. its inner end in an upright wall 9 forming a portion of a gear housing by which said pinion is enclosed, said wall being either integral with or carried by one side of the top portion of the casing l. The outer end of said shaft 8 is journaled in an arm or bracket 10 carried by the casing 1. Said shaft may be rotated either by hand or by mechanical power, a pulley or belt wheel 11 being herein shown as carried by the shaft to permit of the application of mechanical power for driving.

Removably mounted upon the top of the casing l is a top plate or cover 12 which carries or has formed thereon a flanged wall 13 designed to complement the wall 9 in the formation of the gear housing hereinbefore referred to; and surmounting said cover 12 is a casing 14 of box-like form designed as a chest for holding blocks of ice. Said ice chest occupies a centered position on the cover 12, and the latter has therein a large opening 15 registering with the interior walls of the chest. Thus, a block of ice introduced in said chest seats upon the bevel gear 5, or rather upon a plurality of shaving blades 16 which are carried by said gear.

While a less number of blades 16 might be used, it is preferred that four blades, arranged as shown in the drawing, be employed. Said blades are so disposed that the cutting or shaving edges 16 thereof have a truly radial disposition, all having the inner ends of said cutting edges meeting at a central point over said bevel gear. To provide for adjustment so that any desired depth of cut into the under side of the overlying ice block may be made, the blades are made of reverse curve form in cross section and each has therein a pair of transverse slots 17 through which are directed screws 18 by which it is rigidly secured to the bevel gear. The slots 17 are located in an upwardly facing longitudinally extending concavity of the blade, so that by shifting the blade forward or rearwarc with respect to the screws, and then tightening the latter thereon, the elevation of the cutting edge 16 may be increased or decreased, respectively.

Slots 19 provided in the gear 5 beneath the cutting edges of the blades afford passages through which the shaved ice gravitates to the spout portion of the casing,

whence it is discharged to any receptacle located in underlying receiving relation to said portion. Each blade has its inner end spaced a substantial distance from the adjacent blade whose cutting edge is presented in its direction, thereby to avoid interference with the operation of such cutting edge. However, it is to be noted that an acuteangled projection or prolongation 16 is provided at the inner front edge portion so that the cutting" edges will substantially meet at a central point, thus obviating the shaving away of the block in such manner as to leave a central core.

While the ice chest 14 may be of other suitable form or construction, it is at present preferred that the same shall consist of upright angular corner members 14 and panels 14! slidab-le vertically into place be tween adjacent members, said parts having inter-fitting tongues 20 and grooves 21, as shown in F ig. 3.

The casing is supported in any appropriate manner, as by means of legs 22.

\Vhat is claimed is 1. An ice shaving machine comprising a casing having an upper cylindrical portion, a bevel gear disposed horizontally within said cylindrical portion of the casing, means for rotating said gear, a plurality of shaving blades mounted upon the top surface of said gear with their cutting edges occupying substantially radial positions, said blades being of reverse curve form in cross section and having therein transverse slots, screws directed through said slots for securing said blades in adjusted positions, and

means for supporting a block of ice in a position resting upon said blades.

2. An ice shaving machine comprising a casing having an upper cylindrical portion, a bevel gear disposed horizontally within said cylindrical portion of the casing, a drive pinion in operative relation to said gear, means for rotating said pinion, a cover mounted upon the top of said casing and having an opening therein, an ice chest superposed upon said cover in encircling relation to said opening, and a plurality of shaving blades mounted upon the top of said gear with their cuttin edges occupying substantially radial positions, each of said blades being of reverse curve form in cross section and presenting a longitudinally extending upwardly facing concavity, eachblade having plurality of slots transversely crossing said concavitv. and attaching screws directed through said slots, said blades being adapted for forward and rearward adjustment with respect to said screws for elevating and lowering, respectively, the cutting edge of the blade.

In testimony whereof we affix our signatures in presence of two witnesses.
