2 Claims.

This invention relates to a machine for reducing pieces of ice to small particles or chips, one of the objects being to provide a simple and compact structure of this type which can be manufactured at low cost, and when operated will quickly comminute the ice fed thereto.

A further object is to provide the machine with a chipping cylinder utilizing picks spirally arranged whereby the ice, while being subjected to the action thereof, will be shifted from one end toward the other of the cylinder so that different portions of the piece of ice are constantly being presented to the action of the picks.

Another object is to provide a machine which will produc chips of uniform size.

With the foregoing and other objects in View whichwill appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a central vertical section through the machine taken from front to rear.

Figure 2 is a section on line 2Z, Fig. 1.

Figure 3 is a front elevation of the machine.

Figure 4 is a perspective view of a portion of the chipping cylinder and adjacent parts.

Figure 5 is an end elevation of the chipping cylinder, a portion of one of the end guards being shown in elevation and a portion of the feed board being illustrated in section.

Referring to the figures by characters of reference, l designates an inclined feed board having upstanding parallel side boards 2 all of which cooperate to form a chute. A housing including a top 3, and end wall 4 and side pieces 5 is erected over a portion of the chute and is fixedly joined thereto and to a supporting frame 5 which can be suitably braced as indicated at 6.

A table I is pivotally mounted at one end between the side boards 2 as shown at 8 and normally bears downwardly on the upper end of the feed board I.

The lower or outlet end of the chute 9 formed by the feed board I and side boards 2 has a hinged cover it), while secured to the inner sides of the side boards 2 directly opposite each other are arcuate guard strips II which are concentric A cylinder I3 is mounted on the shaft 1-2 and its ends are lapped by the guard strips II which thus serve to prevent particles of ice or the like from becoming lodged between the side boards and the ends of the cylinder. In order that these guards may serve as deflectors they are tapered in the direction of the upper end of the chute, gradually increasing in thickness toward the cylinder. They can be formed of wood or any other suitable material and can be of any size desired.

An annular groove M is formed in the periphery of the cylinder close to one end thereof and receives an endless belt l5 which extends through openings l6 in the top of the housing, the upper portion of this belt being engaged and driven by a pulley IT on, the shaft l8 of a motor 19 supported on the top 3.

The cylinder I3 is sheathed preferably with sheet metal as indicated at 20 and extending through this sheathing and into the cylinder are picks 2! in the form of short spikes each of which is pitched at an angle to that radius of the drum extending therethrough, all of the picks thus being inclined in the direction of rotation of the drum as clearly indicated in Fig. 5. The picks are arranged in spiral rows extending around the drum as shown in Fig, 2 and all of them are adapted to move close to the upper surface of the feed board I. In practice the cylinder is rotated at a high speed in the direction indicated by the arrow in Fig. 5 so that the picks will plow downwardly through any material brought thereagainst. The block of ice to be chipped is placed on the table 1 and is there broken into pieces substantially of a predetermined size. These pieces are then placed in the chute 9 and will move by gravity along the feed board l until they come into the paths of the rotating picks. The picks of each row will successively plow through and chip the ice, sweeping these chips downwardly through the pass between the cylinder and the feed board so that the particles delivered from the lower or outlet end of the chute will be substantially of uniform size. As the picks are spirally arranged, they will engage the ice at different points and will tend to shift the ice from one end to the other of the cylinder during the chipping operation.

The size of the chips produced can be regulated by increasing or reducing the size of the pieces of ice supplied to the cylinder.

ice every one-half inch transversely of the'chute and by making the pass beneath the cylinder not more than nine-sixteenths of an inch at'its more restricted points, approximately twoand one half gallons of chipped ice can be produced per minute.

The motor can be plugged into any convenient electric service outlet and as the entire apparatus is very simple in construction there are no parts which can readily get out of order. The driving belt is protected at all times from the action of the ice because of the location-of the guard in irontthereof.

What is'olaimed is:

1. An ice chipping machine including an includingan inclined trough having-an upper inlet and a lower outlet, a transverse :shaft journaled in the trough, a rotatable cylinder mounted on the shaft and extending transverselywithin the trough,spirally arranged series of picks embedded in and projecting from the cylinder, said picks being pitched in the direction of rotation of the cylinder and beingproportioned and positioned to move close to the bottom of the trough, a motor, a driving beltoperatively connecting the motorrto the cylinder, said cylinder having a groove in one end for the reception of the belt arcuate guard strips disposed adjacent to' the ends of the cylinder, within the trough, one of the guards being positioned in front of the belt and groove.

2. An ice chipping machine including an inclined trough having an upper inlet and a lower outlet, a transverse cylinder in the trough, a protecting sheathing extending around the cylinder,

spirally arranged series of picks extending through the sheathingand into the cylinder, allof the picks being pitchedin the direction of rotation of the cylinder, said cylinder having an annular groove in one end, and said trough con- :stitutingmeans for feeding ice by gravity into the paths of the picks, said picks being positioned tosuccessivelymove into position close to the-bottom of the trough, a motor, a belt connectionbetween themotor and the cylinder, said "belt connection being seated in the groove, and

arcuate deflecting guards in the side portions of v the trough and lapping those portions of the cylinder nearest the inlet, said guards constituting ice deflectors and. one of the :guards. constituting ashield for the-belt connection.
