JOHN .B. ZORN, OF KANSAS CITY, MISSOURI.
ICE SHAVER Ann GRAGKER.
Specification of Letters Patent.
Patented July 19, 1921.
Application filed May 31, 1921. SeriaI No. 473,581.
To all whom it may concern:
Be it known that I, J GEN 13. ZORN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Ice Shavers and Crackers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
Thisinvention relates to a combined ice shaver and cracker and the invention is particularly designed for domestic purposes. One of the objects of the invention is to provide a novel construction of ice shaver and cracker provided with a blade or pick a which may serve for planing or shaving the ice, there being a guard or gage for the blade which will permit it to be utilized as a pick or cracker to break off the ice in larger pieces suitable for iced drinks and the like.
The device is provided with a container or receptacle to receive the shaved or cracked ice which may be subsequently released therefrom after an appropriate amount of shaved or cracked ice has been accumulated.
The preferred construction of my invention has the advantage that it can be oper ated by one hand, the impelling force and the pressure requisite to either shave or crack the ice being imparted to it by one hand in contra-distinction to those forms of ice shavers in which the ice is scraped by pulling the device across the surface of the ice with one hand and applying pressure with the other.
The novel construction of the invention will be apparent by reference to the following description in connection with the accompany ng drawings, in which Figure 1 is a perspective view of an ice shaver and cracker constructed in accordance with my invention, parts being broken away to show the method of adjustably securing the gage and gate partially closing the entrance end of the rece tacle.
Fig. 2 is a vertical, ongitudinal, sectional view showing the position of the gage and gate when the devlce is to be used as a scraper, the open position of the pivoted .cover for the exit end of the device being shown in dotted lines.
Fig. 3 is a vertical, longitudinal, sectional View through the device showing the gage and gate adjusted to permit the blade to be used as a pick for cracking the ice into larger particles than when in the position shown in Fig. 2, and
Fig. 1 is a fragmentary sectional view through one side portion of the gage or gate and one side wall. of the receptacle to illustrate the means for frictionally holding the gage or gate in an adjusted position. i
The receptacle is shown as consisting of a floor portion 1 and two upstanding side walls 2 and 3, the forward portions of the side walls 2 and 3 being inclined clownwardly as at l and 5. The upper and rear portion of the receptacle is closed by a pivoted cover 6 pivoted to the walls 2 and 3 at 7 and 8 and the cover 6 has a downwardly extending portion 9 which closes the rear end of the receptacle. The cover 6 is also provided with flanges lO and 11, which overlap the free edges of the side walls 2 and 3 so as to effect an efficient closer for the top and rear end of the receptacle formed by the bottom 1, sides 2 and 3 and the cover 6.
Fastened to the floor 1 of the receptacle is a blade 12, which may consist of spring metal, preferably spring steel, anchored to the floor 1 at a point distant from the inlet end 13 by the fastening device 14:. The blade lies against the floor 14-. for a portion of its length and it is then curved luoivardly and downwardly, as at 15, the extreme forward cutting edge 16 of the blade being slightly concave transversely, as clearly indicated in Fig. 2, to make it slightly troughshaped, so that it can penetrate beyond the surfaceof the ice cake.
The blade 16 extends slightly beyond the forward end of the floor 1 and through the inlet opening 17, which is partially closed by the gage and gate 18, having downwardly extending flanges 19 and 20, which are pivoted to the side walls 2 and 3, as at 21 and 22. The rear end of the gate 18 has a rearwardly extending lip 23, which underlies the cover 6 so that the joint between the cover and the gate can be sealed su'liiciently to prevent ice from escaping therebetween.
The forward end of the gate is provided with a downwardlyprojecting lip 24 disposed toward the blade and this lip determines the effective area of the opening 17 and serves as a to determine the penetrability of the blade 12; that is, the position of the gage and gate determines whether the blade will shave the ice or crack it. If the' parts are .in the position shown in Fig. 2
J the blade will shave the ice but it the guard lip 24 is moved away therefrom by swinging the rear end of the gage or gate 18 clownwardly, as shown in Fig. 3, then the forward end 16 of the blade 12 can penetrate the ice to a greater depth and remove larger portions in the form of cracked ice.
The lip 24,- also serves as a guard to prevent the ice from receding out 01" the inlet I opening 17 as the device is moved back and forth during the operation thereof.
In order to hold the gage or gate in either of its adjusted positions, I have provided friction latching means, which is shown as consisting of a pressedout boss or projection.
25 on the flange 19, which is adapted to eneither of two pressed-out recessed portions or socket portions 26 and 27 on the side wall 2'sothat if the boss 25 is in the socket 26, the gate or gage 18 will be. in the position shown in Figs. 1 and 2 to permit the device to be used as an ice shaver, but if the boss or projection 25 is in the notch 27, then the gage or gate 18 will be in the position shown in Fig. 3 so that the larger pieces of ice can be removed from the ice cake.
The cover 6 will normally be closed so that as the ice is shaved or cracked from the ice cake and-receivedinto the receptacle formed by the bottom 1, side walls 2 and 3 and cover 6, it may accumulate until an appropriate amount has been received within the re ceptacle or until the receptacle is full, then the operator will swing the cover 6 to open position, as shown in dotted lines in Fig.
so that the contents may be discharged from the rear of the receptacle.
The proportion of the receptacle can be varied but in actual practice the device will be about the size shown in the drawings since the drawings indicate approximately the actual size and the rear end will lit in the handofthe operator so that the thumb will grasp one side and the third and little fingers on the opposite side with the index and second fingers over the top; therefore, the palm of the hand will press the device forwardly into operation and the index and second fingers, lyingon the inclined portion of the gage or gate 18, will assist in retractmg the device.
In actual practicethe device will be tilted on end at an angle of about 415 so that the end of the blade can bite into the ice cake and inasmuch as the blade is resilient, it will spring back toward the end oi the floor 1 when it is shaving or cutting the ice from the cake, thus increasing the opening to pcrinit the shaved or cracked ice to enter the receptacle. On the recovery stroke, however, the blade will sprii'ig into normal position, closing the gap between it and the end of the lip 2%, thereby eliminating the liability of the ice to pass from the receptacle through. the opening 17.
