6 Claims.

This invention relates to newand useful improvements in ice slingers.

The primary object of this invention is to provide a single unit ice slinger adapted for crushing large lumps or cakes of ice to form small ice cubes, fine ice particles or vsnow ice which is directly dropped into a mechanical conveyor that positively feeds the crushed ice to an impeller which in turn forces or throws it through a flexible tube', orthe like, for spraying the ice over the material to be iced. Obviously, the assembling of mechanism for crushing ice, positively conveying it and delivering the ice to the point of use in a single unit has the decided advantage of causing the mechanism to occupy a minimum amount of space and permitting the weight to be reduced to a minimum with the result that the unit may be made portable as well as stationary. 'A further important object of the invention is to provide a single unit of the above men tioned type which has the driven members of its mechanism so arranged relative to each other that a single prime mover may be employed for driving the same with a minimum of transmission equipment and loss of power.

A still further important `object is to provide a screw form of conveyor for feeding the ice from the crusher to the impeller.

Other objects and advantages of the invention will be apparent as the description proceeds.

Figure 2 is a vertical sectional view of the mechanism disclosed in Fig. 1,

Figure 3 is a vertical sectional view of the mechanism embodying this invention and taken at right angles to the sectional view disclosed in Fig. 2, l

Figure 4 is a side elevational view viewed from the opposite side to that disclosed in Fig. 1,

Figure 5 is a top plan view of the mechanism disclosed in the preceding flgures,-

Figure 6 ls a modified form of screw conveyor and impeller mechanism mbodying this invention, and

Figure 'l is a transverse nal view of the mechanism disclosed in Fig. .6.

In the drawings, wherein for the purpose of illustration are shown the preferred embodiments of this invention, and particularly referring to (c1. ss-ss) Figs. 2 and 3, the main housing of the ice slinger unit includes a pair of parallel, substantially rectangularly shaped side plates I II and II. These plates are held in ilxed relation to each other by an end plate I2 which is connected in any suitable manner at its vertical edges to the side plates. A relatively small section I3 of a bottom wall also is xed and is connected at its ends to the vertical' side walls II) and II for assisting in bracing and spacing these latter walls.

The main housing further includes a breaker plate I4 which is pivoted at its upper edge to 1a transversely extending shaft I5 which in turn is carried by brackets I6 on the side plates I0 and VI I. Figs. 2 and 3 best illustrate this manner of mounting the breaker plate I4. It will be appreciated by inspecting Fig. 3 that the plate I4 is arranged in opposition to the xed wall I2 for completing the upper portion of the hous- Figs. 2 and 3 disclose the lower edge portion of the breaker plate I6 as having `pivotally connected thereto a forked member I1 which terminates in a stem I8 intended to pass through an aperture I9 formed in the lower portion of the end wall I2. A stop collar 20 is fitted on the stem I9 to limit pivotal movement of the breaker plate I4 in one direction. outwardly o f the collar 2 0, the stem Iis threaded at 2l and adjustably passes through an aperture in the outer wall of a box-like formation 22 carried by the wall I2. A nut 23 is threaded on the portion 2| of the stem I8. 'Ihis nut has keyed thereto an adjusting wheel 24. By inspecting this mechanism in connection 'with Fig.

, 3, it will be appreciated that the breaker plate I4 maybe adjusted inwardly of the position disclosediin this figure, which position is determined by the stop collar 20. n

Figs. 3 and 5 disclose the-lower edge portion of the breaker plate Il as being provided with breaker teeth 25 which cooperate with the picks 26; carried by the periphery of the roll 21. This roll is keyed to a transversely extending shaft 28 which is iournaled in bearings 29 mounted in any desired manner on the plates Ill and II of the housing. The roll 21 with the picks 26 cooperate with the adjustable breaker plate Il and its breaker teeth 25 for forming ice crushing mechanism. By employing rolls 2l of different diameters and picks 26 of different sizes, and also by adjusting the breaker plate I4 which 'carries the breaker teeth 25, the ice lumps or cakes to be crushedby this mechanism may be wall section ishinged at 3i to the fixed bottom crushed into small ice cubes, line ice particles or snow ice.-i

As the crushed ice is formed by the mechanism Just described, it falls directly into the troughshaped bottom wall section 30. This bottom wall section I3. The remaining side edge of the l bottom Wall is hanged at 32 for being detachably clamped to the bottom of the box-shaped portion 22 by means of the screw and wing nut fastening mechanism I3. The -side wall plate Il is provided with a crushed ice discharge opening 34 arranged in alinement with and corresponding in shape to the trough portion 30 of the bottom wall of the housing. l

suitably bolted, or otherwise fastened. to the outside of the wall I is an impeller housingji. A bearing le is suitably mounted on the outer wall of the impeller housing 3i. In" alinement with the bearing 3B is a second bearing I1 which is suitably secured to the outer side of the wall Il. 'Ihese bearings support a transversely extending shaft l which is of suilicient length t0 project appreciably outwardly of the bearing l1 to provide an end portion 38a to which a prime mover may be drivingly connected in any desired' manner.

Within the trough-shaped bottom wall ll. the shaft 3l is provided with a flight i! that forms a screw conveyor for feeding the crushed ice deposited in the trough-shaped bottom Il of the housing to and through the opening Il in the housing wall Il. This conveyor fed crushed ice is delivered to the center of the centrifugal impeller 4l which is suitably keyed to the shaft 3l. The impeller 40 is formed of end walls Ila and 40h with an axial inlet opening c formed in the wall llb. 'Blades d extend radially and are joined to the end walls at their longitudinal edges.'

with the exception of the axial inlet and radial outlet openings.

This design of impeller has been found to be very desirable for handling ice particles as it maintains the ice out of contact with the walls of the stationary housing to the greatest extent possible, .thereby preventing formation of ice on the inner surfaces of the housing walls and the drag of the blades'lld and the ice particles being impelled over thev housing walls which would retard rotation of the impeller and cause breakage of the ice particles.

It will be appreciated that the impeller must ro- The housing 2S is provided with an outlet 4|.' (see Figs. l and 5). A flexible tube, or the like,

is intended to be connected to the outlet 4I so that'the cnished ice thrown through the outlet of the impeller housing may be controllably delivered to iced.

The shaft 28 is disclosed in Figs. 2 and 4 as having mounted thereon a sprocket 42 over which is trained a sprocket chain 'This chain also is trained over a sprocket M suitably keyed to the shaft 38. It will be appreciated that by. applying power from a single prime mover to the end Ila of the shaft 38, the icecru'sher rollv 21, the screw conveyor night 39, andthe centrifugal impeller '40 will be directly driven thereby..

A suitable housing Il is connected to the 'aide wall plate Ii of the main housing for and sprayed upon the material to be a main drive shaftfor all theton mechanism employed for driving the shaft 28 from the main shaft 38.

When desired, a shelf as shown best in Figs. 3 and 5, may be employed for supporting large lumps or cakes of ice'prior to; feeding the same into theopen upper end of the main housing where they are operated upon by the picks 2l ofthe crusher roll 21. l

Figs. 6 and 7 disclose a modified form of screw conveyor and centrifugal impeller. This modification consists of two screw conveyor flights 41 which are suitably fastened to a main drive shaft Il which corresponds to the shaft n of the preceding iigures. The impeller unit 49 has surfaces or blades 5I which are suitably connected to or formed integral with the flights 41 of the screw conveyor so that continuous surfaces will connect the conveyor flights and the impeller blades. 'This modified form of combined screw conveyor and impeller are housed in the same members as that disclosed in and described in connection with the preceding figures. The same reference characters, therefore, will be applied. It will be un'- derstood that the number of nights 41 carried by meshes; n may be varied as desired and that the use of two in these gures is merely illustrative.

It will be appreciated that the single unit ice slinger embodying this invention is capable of handling large lumps or cakesof ice for crushing the same and that'the crushed ice will be uniformly and quickly delivered from the unit to the point of use where it` may be sprayed upon the material to be iced. The compact arrangement of the various elements of the unit enables the same to be made portable by mounting upon any form of conveyance and also permits large lumps or cakes of ice to be delivered to the same without being eleva.' to a considerable height. The compactness oi the' device, ofcourse, will cause it to occupy a minimum-'amount of space and have a minimum weight.

The use of a mechanical conveyor for feeding the crushed ice formed by the cooperating picks 28- and breaker teeth 25 quickly and uniformly t'o the impeller mechanism has numerous advantages which will be set forth as follows:

(a)v It permits the use of wide crushing rolls and avoids the necessity of placing the crusher 'aconsiderable distance above the center of the' impeller which would be necessaryl if a chute, or

other form of gravity feed were used for delivering the crushed ice.

(b) -It feeds the .ice to thevcenter of the impeller and thus the breakage of the ice cubes is less with this amusement than would loccur if -a gravity form of'feed were employed. (c) It eliminates thetendency of the crushed ice to choke at any point between the crusher and the impeller and provides a more uniform feed of the crushed ice with the result that maximum. eiiiciency is obtained. (d) It also enables a *single shaft to be used Ifor the screw conveyor and the impeller and as of the rotating parts oftheentlreunit. f

It is believed .that the inode of operation of the ice slinger unit embodying this invention will be readily understood fromv the preceding descrip?- tioxr and that no further explanation will be vItzis'to be understood thatv the forms of this invention herewith shown 'and described arev to be taken as preferred examples ofthe same, and
