ICE CRUSHER Filed Deo. 8, 1944 A Trams/5% a f the size desired.
Patented Apr. 23, 1946 UNITED, s'rA'rss PATENT I'orricis:
assassz This invention relates to improvements in ice crushers and refers more particularly to an ice crusher in which the crusher members are adjustable to produce ice particles or pieces of ice The crusher is adapted for the preparation of crushed ice for all sorts of cold beverages, ice
packs or wherever crushed ice is needed.
One object of the invention is to provide an ice crusher which is small, compact and rugged in construction and completely enclosed to prefvent| ice particles from being scattered during the ice crushing operation.
Another object is to provide a crusher construction which is portable and may be easily moved from place to place convenient to the person who is serving the beverage and at th same time offering a crusher which is attractive in appearance.
Other and further objects of the invention will appear from the following decription.
In the accompanying drawing which forms a part of the specication and is to be read in conjunction therewith, and in which like reference numerals are used to indicate like par-ts in the various views,
Fig. 1 is a front sectional view of an ice crusher embodying the invention taken along the line I-I in Fig. 2 in the directionof the arrows,
Fig. 2 is a. side sectional View taken along the line 2-2 in Fig. 1 in the direction of the arrows,
Fig. 3 is a detail of a modified type of link for adjusting the position of the hopper.
The crusher comprises an upright standard iIl in the upper portion of which is pivoted on trunnions II an ice hopper I2. Within the hopper and on opposite sides thereof are a plurality of ns I3 which extend from the sides of the hopper in the path of crusher members or'claws Il. The crusher members are mounted upon a rotating shaft I5 which shaft extends with clearance through the hopper. Shaft I5 has` bearings I5a and I5b in the standard and is rotated by means of a handle I8 attached to the shaft on the outside of the standard. The bottom of the hopper is open and beneath it pivoted at I1 is a dump receptacle I8. Below the open bottom of the hopper and tted into the side oi" the standard is a. cup I9. The front lip of the cup as itis slid into the standard contacts the lip lila ofthe pivoted receptacle, raising it to full line position as shown in Fig. 2 so that the crushed ice will fail directly into the cup. When the cup is removed from the standard the weight of the receptacle rotates it into the dotted line position beneath the hopper and prevents ice particles or water from dripping into the bottom of the standard.
In operation the lid Ida pivotedjt lb on the standard -is opened and chunks of ice placed in 5 the open top of the hopper I2. The thumb screw 2l which is threaded into a link member 2| pivoted at 22 to the hopper is adjusted to obtain proper spacing of the ns Il with respect to crusher. members Il. By advancing or retarding l l0 the screw 20a the hopper is moved upon its pivot Il. Between the link 2l and a washer 23 against the standard is a buffer spring 24. Adjustment of the screw 20a as suggested positions the fins I3 and crushers Il to crush the ice into proper size. In the modined form of construction shown in Fig. 3 screw 20a is replaced by a notched link 25 which hooks into the lower edge of an aperture in the standard in any desired position, the lengthening or shortening of the link moves the hopper and adjusts the distance between the cutters or fins I3 and crushers Il.
After the ice is placed in the hopper and the hopper adjusted the handle I 8 is rotated. Rotation of the crusher members coacting with the uns on the sides of the hopper crushes the ice which falls into\cup I9. When the cup is lled it is withdrawn from the standard and dumped into the container iniwhich it is to be used. When the cup is withdrawn from the standard the dump receptacle I 8 moves omits pivot into the dotted line position and catches\ small ice particles or water which drips from the hopper or crushing members. When the cup is reinserted the front lip of the cup engages the lip Ita on the pivoted From the foregoing it will be seen further that the invention is one well adapted to attain the ends and objects herein set forth together with other advantages which are obvious and which are inherent to the structure. It will be understood that certain features and subcombinations are of utility Aand. may be employed without referdump receptacle and moves it from below the 2 h ence to other features and subcombinations. This is contemplated by and. ist-within Ithe scopev of the As many possible embodiments may be made oi.' the invention without departing from the scope thereof it is to be understood that all matter herein set forth or showniin the accompanying drawing is-to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention, I claim:
1. An ice crusher comprising in vcoxnli'ination a standard, an open bottom hopper pivoted adjacent its top in the upper portion vof the standard, fixed crushing fins in the hopper. a shaft bearing in the standard and extending through the hopper. rotatable crushing elements mounted on the shaft and coactiml.r with the iins in assenso the hopper to crush ice, a substantially horizontal adjustable link between the standard and the lower open end of the hopper for shifting the hopper on its pivot to vary the relationship between the crushing elements and ns.
2. An ice crusher as in claim 1, including a removable cup beneath the hopper. a gravity dump receptacle within the standard and pivoted on the hopper beneath the hopper pivot, said'receptacle having means engageable by the lip of the cup to rotate the receptacle from the bottom of the hopper when the cup is below the hopper and permit rotation of the receptacle upon its pivot-to cover the bottom of the hopper when the cup is removed. v
