WILLIAM E. PENN, OF LAKE MILLS, WISCONSIN, ASSIGNOR TO' CREAMERY PACKAGE MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A. CORPORATION OF ILLINOIS.

non-BREAKER.

Patented Julyfi, 1912.

To all whom it may concern Be it known that I, WILLIAM E. PENN, a

,citizen of the United States, residing at Lake Mills, in the county of Jefferson and State of Wisconsin, have inventedv certain new and useful Improvements in Ice-Breakers, of which the following is a specification.

This invention relates to machines for breaking or chipping ice, of the type in which a plurality of picks are mounted in the periphery of. a drum which Is adapted to be rotated to carry the picks into engage.- ment with a block of ice, for the purpose of breaking the block into fragments of a size suitable for use in ice cream freezers and various other places.

One of the objects of the invention is to improve the manner of mounting the picks in the drum.

Another objectis to provide an improved adjustable mounting for the stationary comb.

A further object is to produce an 1mproved sectional casing, the parts of which are separable so that the drum mounted therein may be easily removed to permit repairs or renewal of the picks.

The invention also relates to the further features of improvement in ice breaking machines hereinafter set forth.

In the accompanying drawings, Figure 1 is a sectional view of an ice breaker embodying the features of my invention, the view being taken in the plane of line ll of Fig. 2. Fig. 2 is a front. elevation of the machine. Fig. 3 is a section on line 33 of Fig. 2. Fig. 4 is a perspective view of one of the picks. Fig. 5 is a fragmental section through the drum showing a pick in place therein. Fig. 6 is a fragmental plan view of the drum showing one ofthe pickreceiving openings. Fig. 7 is a section on line 7'7 of Fig. 5. Fig. 8 is a detail View of a washer used in the machine.

The embodiment of my invention herein shown comprises a casing having side walls 1 and 2, and a curved wall 3 extending be tween said side walls, said curved wall having flanges 4; at its side edges adapted. to be bolted to the walls 1 and 2. The curved wall 3 terminates short of the forward and lower sides ofthe side walls 1 and 2 to provide a feeding opening 5 and a discharge opening 6.

A drum 7 is rotatably mounted in bearupper and lower edges.

ings 8 in the side walls 1 and 2, said drum carrying a plurality of picks 9 upon its peripher The side walls 1 and 2 are preferably divided on lines 1 extending vertically ;upward and horizontally to the right (Fig; 1.) from the bearings 8, to form a movable casing section 10 which is hinged at 11 upon the stationary portion of the casing, saidmovable section being arranged to swingupwardly topermit the drum 7 to be removed for the purpose of repairs or for renewal of the picks 9. The bearings 8 for the drum 7 are split diagonally as shown in Fig. 3, one half of each of the bearings preferably being formed integral with the stationary portion of the casing, and the other half 8 being detachably connected to the. fixed bearing sections. By this manner of dividing the bearings 8 all stress is thrown against thafl half of the bearing which is carried by the stationary portion of the casing. Flanges 12 on the bearing sectionsare arranged to receive bolts 13 for clamping said bearing sections together.

The picks 9 may be of any suitable numher and are preferably staggered upon the periphery of the drum 7. The rear portion of each pick is of I form and comprises a web 14. having flanges at its The web 14: is adapted to be inserted into an opening or slot 16 formed in the wall of the drum 7, the flanges 15 on said web contacting faces 17 formed on the inner and outer sides of the drum. The pick is wedged firmly in its slot 16 and is thus held firmly in its place in the drum. In. the present instance, I have provided for this wedging effect by forming the faces 17 at the outer anti inner sides, respectively, of the drum 7 in planes which converge in the direction of rotation of the drum, and by making the flanges 15 on opposite sides of the pick 9 converging toward the point of the pick, as clearly shown in Fig. 5. The slot 16 is somewhat widened at its entrance 16, to permit the lower flanges 15 to pass to the inner side of the drum. It will be noted that the engagement of the picks 9 with the ice will not tend to loosen or dislodge the picks from the drum 7 ,-but on the contrary, will drive said picks more securely into the drum. This manner of mounting the picks obviates the necessity for using screws or other fastenings which might work loose,

' upper edge,

therein, said openings the steps 21 are the pair of steps in 22, said washers having or become rusty so that they could. not be removed when it became necessary to re- The picks 9 are arranged to coiiperate with a stationary comb 18 having, 1n this,

instance, a dove-tail connection with aplate 19 which ,forms a portion of the front wall of the casing. Sa1dplate is pivoted at its as at 19*, to the side walls 1 and 2 and is adapted to be swung towar and away from the drum 7 to adjust the comb 18 with relation to said drum. The side walls 1 and 2 may have openings 20 formed in one edge thereof in which steps a rod 22 is adapted to lie. The lower end of the plate 19 is adapted to rest against the rod 22. .As will be'seen from Fig. 1,

located at successively greater distances from the drum 7 'so that the comb 18 may sired distance from said drum.

Washers 23 may be placed on the rod projections 23 thereona'dapted to fit in the openings 20 alongside the rod in any of the three positions of the latter so as to hold the rod in which it has been placed. The washers 23 are held in place by a head 22 and nut 22 on the rod 22. (Fig. 2.)

In practice, several of the combs 18 will be provided, the teeth of the different combs varying in their spacing so that the ice may be broken into grades varying in-size.

When it is desired to change the comb 18, the rod 22 is removed and the plate 19 swung outwardly. The comb 18 may then be slid longitudinally out of its dovetail recess and another one substituted.

the lower portion of the casing directs the broken ice falling between the drum 7 and comb .8 into the lower portion of the casing. Said plate forms the lower portion of the forward wall of the casing.

The drum 7 may be driven in any suitable way. I have herein shown a tight pulley 25 and loose pulley 26 fixed on the drum shaft so that the drum may be driven by power if desired. A hand wheel 27 may also be fixed upon the other end of the drum shaft to permit of turning the drum manually.

In operation, a cake of ice is placed in the feeding opening 5 of the casing, the cake resting against the drum 7 and the plate 19. The drum is then rotated to carry the picks 9 successively into engagement with the cake of ice to break up the ice into smaller pieces. In passing downwardly between the picks 9 and the comb 18 these pieces are broken up into fragments of the having steps 21 be positioned at'the de-- of the drum.

.ing a desired size. A suitable instrument such as a shovel may be inserted through the discharge opening 6 for withdrawing the chi edice from: the casing. V
