6 Claims. (Cl.' 83-63) This invention relates to implements for crushing ice, particularly ice cubes such as are made for table use in automatic domestic refrigerators.

The object of my invention is to provide a simple, reliable and inexpensive hand operable def vice whereby a number of ice cubes may be crushed at one time without splash or spill, and the crushings discharged, finely divided, into a tumbler or other receiver.

In the drawing, Fig. I is a perspective View of my improved ice crusher.

Fig. II is a longitudinal sectional view of the device with its opposing jaw members in the normal open position.

Fig. 111 is a view like Fig. II with the jaw members in crushing position; and,

Fig. IV is a cross sectional view taken as indicated by the arrows IV-IV in Fig. II.

As depicted in these illustrations, the ice crushing device of my invention comprises a pair of opposing jaw members l, 2 which jointly form an open ended tapering holder 3 capable of accommodating, at one time, a number of ice cubes C (Fig. II) inserted through its larger or receiving end. By means of a pair of pivot links 4, one end of the top jaw member 2 is suspended from a cross rod 5 which is supported by a pair of integral upward lug projections 6 of the side walls 7 of the bottom jaw member 1 at the corresponding end of the device. Fulcrumed between another pair of upstanding lugs 8 at the opposite end of the bottom jaw member 1, is an operating handle 9 of suitable form and length to be conveniently grasped in one hand, together with a similar companion handle 10 forming an integral extension centrally of one end of the cross web 11 oi' said bottom jaw member. A pair of complementary longitudinal links 12 connect a cross rod 13, journaled in bearer projections 2' on the jaw member 2, between the swinging ends of the suspension links 4, with upward crank projections 14 oi' the operating handle 9; and a helical spring 15 serves to normally hold the free end of the top jaw member 2 against the pivot lugs 16 of the operating handle 9. As shown, the spring 15 is attached at one end to the cross rod 5, and at the other end to a central lug 17 on the top of the top jaw member 2; and said spring passes over a roller 18 mounted in the interval between the spaced portions of the links 12. The jaw members 1 and 2 are respectively provided with tooth-like ice gripping projections 19, 20 which are inclined away from the larger or receiving end of the holder 3.

In use, the device or holder 3 is held substantially in vertical position with the jaw members 1, 2 separated, as in Figs. I and II, when the icecubes C, are insertedtlnough the larger end of the holder 3. Incident to depression of the Voperating handle 9 relative to the companion han- 60 diev 10, it will be seen that the top jaw member 2 is moved longitudinally in a direction away from the smaller or mouth end of the holder 3.` and at the same time toward the bottom jaw member 1 through the action, on the one hand, of the links 4, and on `the other hand, through downward pressureof the operating: handle 9 upon the .free end of the said jaw 2, after the mannershown in Fig. III. As a consequence of' the approach of the top jaw member2 to the bottom jaw mem- 70 ber 1, the'ice cubes C between the two are crushed. Uponrreleas of the operating handle 9, the spring 15 becomesY effective in drawing the upper jaw member 2 upwardand forward to the normal position illustrated in Figs. I and II, whereby, with the assistance of the projections 19, 20, the crushed ice particles are fed forward toward the smaller or discharge end of the holder 3. From the foregoing it follows that by repeated depressions of the handle 9, the ice cubes C will be progressively broken up and the crushings ejected, without spill or splash from the smaller end oi.' the holder 3.

As shown in Figs. I-III, the upward lugs 6 of the bottom jaw member 1 are pierced with holes 851 21 at intervals vertically. Accordingly, the position of the rod 5 may be changed to predeterminea smaller outlet for the holder and crushings of correspondingly smaller size. For convenience in making such changes, the rod 5 is provided at 90, one end with an easily removable cotter pin 22, see Fig. IV.

Having thus described my invention, I claim:

1, An ice Crusher comprising a pair of opposing jaw members with ice gripping projections, means at one end of the crusher pivotally-supporting one of the jaw members relative to the other, crank-actuated linkage operatively-coordinated to the pivotal means and engaging the free end of the supported jaw to longitudinally move the latter in one direction angularly toward the other jaw member to crush the ice, and means normally holding the jaws apart effective to retract the pivotally supported jaw in the opposite direction whereby the projections afore-v said eject the crushings.

2. An ice Crusher comprising a pair of opposing jaw members embodying inclined projections and jointly forming a tapering holder for ice cubes, a pivot linkage at one end of the Crusher Il 2'Yfl" supporting one of the jaws relative to the other, a crank and connecting links operatively-coordinated to the pivot linkage and coacting with the free end of the supported jaw member to move the latter longitudinally in a direction away from the smaller end of the holder and at the same time angularly toward the other jaw member to crush the ice, and retractile means normally holding the jaws apart effective to automatically draw the supported jaw reversely whereby the inclined projections aforesaid eject the crushings from the smaller end of the holder.

3. An ice crusher comprising opposed stationary and movable jaw members embodying inclined teeth and jointly forming a tapering holder for ice cubes, pivoted links and a cross rod supporting the movable jaw at one end relative to the stationary jaw, a cranked operating handle engageable with the free end of the movable jaw and fulcrumed to the stationary jaw at the other end of the Crusher, and means operatively connecting the pivoted links to said handle whereby the suspended jaw is movable longitudinally of the stationary `jaw in a direction away from thesmaller end of the holder and simultaneously angularly toward said stationary jaw to crush the ice cubes. A

4. An ice crusher comprising a pair of opposed upper and lower jaw members jointly forming a tapering holder for ice cubes, said jaw members each embodying ice gripping teeth on their opposing faces inclined away from the larger end of the holder, links` suspending the upper jaw relative to the lower jaw at one end of the crushf er, an operating handle fulcrumed to the lower jaw remote from the suspension links with complemental links operatively connected to the sus' pension links, spring'means normally holding the free end of the suspended jaw in kcontact with the handle fulcrum, and said handle serving to move the suspended jaw member in a direction longitudinally away from the smaller end of the holder and at the same time angularly toward the lower jaw member to crush the ice, and then under the spring influence reversely to thereby cause the inclined teeth aforesaid to eject the crushings from the smaller end of the holder.

5. An ice Crusher comprising opposing top and bottom jaw members, one end of the top jaw member being suspended, by means of pivot links, from lugs upstanding from the bottom jaw at the corresponding end; an operating handle pivoted between upstanding lugs at the opposite end of the lower jaw member; longitudinal links connecting the suspension links with a crank center on the operating handle; and a spring holding the free end of the upper jaw member in contact with the handle at the region of its pivot, whereby, as the handle is depressed, the upper jaw is moved longitudinally of the lower jaw and at the same time toward it to crush the ice inserted between the two jaws, and, as the handle is released, the action is reversed under the pull of the spring to discharge the crushings.

6.` An ice Crusher comprising opposing jaws,

jointly forming a tapering holder for ice cubes,- one end of the top jaw member 4being suspended,-

by means of pivot links, from lugs on upward side walls of the lower jaw member at the corresponding end of the latter; an operating handle pivoted between the side walls of the lower jaw member at the opposite'end; longitudinal links connecting the suspension links aforesaid with a crank center on the operating handle; and a spring holding the free end of the upper jaw member in contact with the handle at the region of its pivot, whereby, as the handle is depressed, the said upper jaw member is moved longitudinally of the lower jaw member in the direction away from the smaller end of the hold-- er and at the same time toward the lower jaw to crush ice placed within the holder, and, as the handle is released, the movement of the upper jaw is reversed under the pull of the spring to eiect discharge of the crushings from the smaller end of the holder. f
