Application led September 9, 1921. Serial No. 499,476.

' To all who/122er may con cern Be it known that l, Henson M. Jnnovrn, a citizen of the United States of America, and a resident of Davenport, county of `Scott., and State of Iowa, have invented certain new and useful improvements in Ice-Shavof which the following` is a full and clear specification.

The object of this invention is to provide a simple. inexpensive apparatus for reducins ice tosmall particles by the sh aving method vand the invention consists of certain novel features of construction hereinafter described and Claimed.

In the drawing- Fig. 1 is a side elevation of my machine;

Fig. 2 is a front elevation thereof;

Fig. 3 isa vertical section of the machine;

Figs. l to 7, inclusive, are views of details hereinafter described.

Referring to the drawi reference-numerals, 10 de upon which is supported a casing 11 consisting of two circular halves one of which. is bolted to the base and the other is secured to the former by bolts 12. W'ithin this casing is mounted to rotate a disk 18, which is aiiixed to a shaft lll journaled in bosses formed integrally with the walls of the casing members and provided at one end with a hand-wheel 15 for rotating it, it being obvious, however, that a small electric motor or other power may be used instead of this hand-wheel, The disk is provided with a series of radial slots or openings, and in each one of these openings is mounted a sliavingblade, every alternate blade having serrated teeth; the plane-edged blades are designated 16, while the serrated-edged blades are designated 17. Ars shown clearly in Figs. 5, 6 and 7, the shaving-blades are formed with bevelled cutting-edges, and the serrations or teeth on the blades 17 are formed by grooving the blade transversely entirely across its underside (as indicated by the closely-spaced lines in Fig. 6), said grooves cutting through the thin bevelled edges of the blades and thereby forming the teeth.

At the rear side of the knife-casing is arranged a hopper 18 adapted to receive the lumps of ice to be shaved. FThis hopper is desirably cast integral with the rear plate of the casing 11 and is located at the left of the center of rotation of the knife-disk. its botannexed by tom wall 19 curves backwardly and upfor the ice-lumps. The front sideof the hopper opens into the casing 11 its full height, so that the ice-lumps may be pressed directly against the `downwardly-moving edges of the yknife-bla .lcs, to thus shave oil the ice and deliver it through the slots in the disk into achute 2O integral with the front-plate of the casing 11, this chute widening downwardlyfto an open lowerend, where the shaved ice will be delivered. a suitable receptacle being arranged `below the top plate of the base 10 to receive the shaved ice.

To press the ice-lumps against the shaving-knives and thus automatically feed the lumps to the knives, 1 arrange a gravityfecd device consisting of a head-plate 21 pivoted at 22 on the upper edges of the sidewalls ofthe hopper 18, at a point near the casing 11, This pressure-head 21 is approximately the width of the hopper 18 and, by reason of the fact that it is pivoted near the casing, at 22, it tends to normally swing toward the casing. An arm 22 is rigidly aflined adjacent. to the lower edge of the pressure-plate 21 for the urpose of conveniently lifting it out of tie hopper to replenish the ice-supply therein. This arm is enlarged near its lower end at 28 to form a weight which is sufficiently heavy to force the pressure-plate 21 against the ice with the desired pressure, thereby eliminating t-he necessity of manually forcing the ice against the knives. The arm being rigidly affixed to the plate, it supports the weight clear of the bottom wall 19 and thus prevents frictional resistance. To prevent the pressureplate contacting with the knives after eX- haustion of the ice, l provide the armv22 with a stop-lug 24, which is so located as to strike against the rear edge of the hopper 18 when said pressure-plate nears the knives.

at will be observed that my apparatus is simple and is capable of being inexpensively made, and, further, that the feeding of t-he ice to the knives is accomplished without manual pressure. A further feature of importance is the alternate arrangement of serrated and plane shaving-knives, whereby the serrated edges score the ice ahead of each plane-edged knife7 thereby reducing the power required for cutting the ice to a minimum and making the machine very easy `to run.

It will be observed further that the casing l1 covers the cutter-wheel closely on both sides except at the places where the delivery and discharge chutes are located,

vand both of these are positioned wholly to one side of the driving-shaft, which permits the shaft to be mounted in suitable bearings formed on the outside of the inner side-wall of both the delivery and discharge chutes.

The nature and scope of the invention `having` been thus indicated and its preferred .cutter-wheel mounted to rotate in said casing, said feed-hopper and delivery-chute be* ing positioned directlyv opposite to each other and entirely to one side oi the center of rotation of the cutter-wheel, whereby `both sides of the cutter-wheel are closely confined in the casing except at the points where the feed-hopper and delivery-chute are positioned.

- 2. An ice-shaving machine embodying a Hat-faced cutterwheel, a guard-casing surrounding said cutter-wheel and having flat 'inner-faces which lie closely. adjacent tothe Hat faces of the cutter-wheel, a feed-hopper and a delivery-chute forming part of the 'facingand being located on opposite sides thereof in alinement with each other and opening to said cutter-wheel, supporting bearings for the cutter-wheel formed on the side-walls and outsidevof'the feed-hopper and delivery-chute, and Jfeeding means on the feed-hopper for automatically forcing the ice against the cuttin0'wheel.

3. An ice-shaving machine embodying a fiat-faced cutter-wheel provided with alternately-arranged serrated and plain-edged ciutters to produce inely-shaved ice, a guard-casing surrounding said cutter-wheel and having fiat inner-faces which lie closely adjacent to the flat faces of the cutter-wheel7 a feed-hopper and a delivery-chute forming part of the casing and located on opposite sides thereof in alinement with each other and opening to the cutter-wheel wholly to one side of the axis thereof, said fiat inner` 'faces of the casing in their close relation to they cutter-wheel :forming strippers for the cutter-wheel at the edges of the casing adjacent the feed-hopper and` discharge chute to prevent the yfinely-shaved ice passing into the bodyvoiA the casing, and means in the eedfhopper for feeding the vice against the cutters.

In testimony whereof I hereunto affix my signature. 1

yHORACE M. JEROME.
