To all whom it may concern:

Be it known that I Enwm C. MILLER, a citizen of the United States of America, residing at Sabina, in-the county of Clinton and State of Ohio, have invented new and useful Improvements in Ice-Crushers, of which the following is a specification.

This invention relates to ice crushers of that class in which toothed rollers are employed to exercise a crushing action upon a piece or lump of ice supported in a suitable casing for the purpose of reducing'the same to lumps of smaller dimensions without shaving or powdering the same, the special purpose being to supply crushed ice to be used for cooling drinks, the same pre sentinga pleasing and desirable appearance and being less liable to melt rapidly than shaved or powdered ice.

The invention has for its object to simplify and improve the construction of the crushing apparatus, to provide means whereby one of the crushing rollers may be adjusted to re late the size of the product and to provide a casing of simple and improved construction Wl'llCll shall be equipped with an outlet spout beneath which a glass receptacle may be placed to receive the crushed ice.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawings has been illustrateda simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

- In the drawings,Figure 1 is a pers ective view of an ice crusher construete in accordance with the invention. Fig. 2 is a top plan view of the same with the upper portion of the casing removed. Fi 3 is a sectional detail view taken on the hue 3 -3 in Fig. 2. Fig. 4 is a vertical sectional view of the machine showing the parts assembled.

Fig. 5 is a perspective detail view showing the lid or cover inverted. Corresponding parts in the several figures I are denoted by like characters of reference.

cent to its upper edge with flanges 2 and.

upstanding lugs 3 to confine the lower end o a casm 4 which, when mounted in position, may e secured by a spring latch member 5 engaging a lug 6 adjacent to one side of the lower end of the casing; the opposite side of the casing being provided with s urs 7 to engage apertures 8 in the upstan ing lugs 3, thus enabling the parts to be securely connected together when assembled, but in such a manner as to permit the said parts to be readily disassembled when required. The hopper A is provided at its upper edge, adjacent to its front and rear ends, with stationary boxes or bearings 9 wherein a shaft 10 carrying a crushing roller 11 is supported for rotation. Adjacent to the stationary boxes 9 are slidable or movable boves 12 for the adjustment of which"any suitable means may be provided, such as screws 13 operating in threaded sockets in the boxes, said screws being swiveled in the casing and provided with handles 14, whereby they maybe conveniently turned to effect the desired ad- 'ustment of the boxes. The boxes 12 afiord earings for a shaft 15 carrying a crushing roller 16.

The shafts 10 and 15 may be made im tegral with the rollers 11 and 16, and they OO are equipped with intermeshing cog wheels 17, 18, the teeth of which are of sufficient length to intermesh at various adjustments of the boxes or bearings 12 in which the shaft 15 is supported. One of the shafts is also provided with a pinion 19 meshing with a spur wheel 20 which is supported for rotation upon a gudgeon 21 extending from the hopper, said spur wheel being provided with a crank handle 22 whereby it may be conveniently rotated for the purpose of. actuating the shafts carrying the crushing rollers.

The crushing rollers, which may be appropriately made of cast iron, are provided with radially extending teeth 23 which are arranged in such a manner as to break joint or intermesh w! h each other, as shown, thereby seizing upon a lump or lumps of ice supported above said rollers and breaking therefrom pieces which are subsequently fragments of the desired size which may be regulated as herein described by proper adjustment of the bearings whereln one of the rollers is supported for rotation.

The casing 4 which is supported upon the hopper is made to fit snugly within the up-. standing flange 2, the front and rear ends of said casing being slightly recessed at 31 to make room for the adjustable bearings 12. Said movable or adjustable bearings are thus guided between the upper edge of the hopper 1 and the lower edge of the caslng most coil of which is provided with cross bars 27 constituting a frame which is adapted to press downwardly against the contents of the casing.

In the operation of this device, by removing the lid or cover 25, the casing may be filled with ice, one or more lumps of which may be placed within the casing. The cover is then placed in position, and the frame at the lower end of the coiled spring will engage and press downwardly against the ice which is thus forced in the direction of the crushing rollers. When crushed ice is desired, a glass or other receptacle 28 is placed beneath the discharge spout, and the crushing rollers are then rotated by means of the crank or handle 22, thus reducing the ice to fragments of the desired size which are discharged into the glass or receptacle. It will be particularly noticed that the fragments are not in any sense reduced to shavings or to powder which would melt very rapidly, but all said fragments on the contrary will be in the shape of small lumps presenting a very pleasing and attractive appearance when used in the manufacture of cooling drinks or for other purposes.

The hopper of the improved device is preferably provided with legs or support ing members 29, and it may be, in practice, mounted upon a suitable base, as indicated at 30. This improved device may be utilized on a larger scale for the purpose of crushing ice for use in the manufacture of ice cream and for similar purposes. The device may also be used for crushing or comminuting other substances than ice. When thus used, additional rollers may be employed for the .purpose of increasing the capacity of the machine.

Having thus described the invention, what is claimed as new, is

In a device of the character described, a hopper having upstanding flanges, roller carrying bearings supported upon the upper edge of the hopper adjacent to and within the upstanding flanges, a casing mounted upon the hopper within the flange, said casing being recessed to permit adjustment of the roller carrying bearings, means for securing the casing in position, and means for adjusting the roller carrying bearings.

In testimony whereof I aflix mysignature in presence of two witnesses.
