DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first to FIGS. 1 through 8, an ice shaving device, embodying the invention, comprises an assembly A including a receptacle or body member 1 and a cover 2, with body member 1 being fixedly secured to a support base 3. Base 3 has a general conical shape with a hollow interior, and is formed with a bottom opening in which there is positioned a suction plate 4 formed of a soft elastic material, such-as rubber. A pull rod 4-2 is fixedly secured to the upper central portion of section plate 4, and is reciprocal vertically by virtue of its coupling to a crank and cam member 4-1.'Upward and downward movement of crank 4-1, which has a portion projecting outwardly through a lateral aperture in base 3, causes the upper central portion of suction plate 4 to move down and up. Thus, when the projecting portion of crank 4-l is pushed downwardly, the upper central portion of suction plate 4 is lifted and a vacuum is created between its under surface and a surface on which base 3 is supported. Thus, suction plate 4 can be made to adhere to the. top of the table so that assembly A is fixed in position on the table.

Receptacle or body portion 1 is relatively elongated and is semi-cylindrical for a major portion of its length. I

mounted an ice shaving blade 5. Adjacent the upper end of the body member 1, there is mounted an internally threaded bushing 7 which supports a rotatable shaft 16, in a manner to be described. The function of end wall 6 is to engage, during shaving, the surface of a block of ice a contained in body member 1. Block a is revolved along the interior surface of end wall 6.

Blade is secured by a bolt 8 to end wall 6 to project through an aperture 9, in this end wall, in accordance with the adjustment of bolt 8. Blade 5 is formed of a metallic material and shaves the block of ice a slidingly revolved along the inner surface of end wall 6. By adjustment of bolt 8, the amount of projection of blade 5 into body member or receptacle 1 can be adjusted, and the larger the inward projection, the coarser is the shaving of the ice.

Body member 1 has guide grooves 32 extending along the upper edges of the semi-cylindrical portion and continued into its cylindrical lower or inner end portion. As best seen in FIG. 3, the lower longitudinal edges of cover 2 are slidingly engaged in grooves 32. Cover 2 is formed of a suitable material, such as a transparent synthetic resin, and is relatively elongated with a substantially semi-cylindrical cross section roughly corresponding to that of the major portion of body member 1. The lower or inner end of cover 2 is open, and a circular end wall 10 integral with cover 2 is arranged to close the upper end of assembly A. For charging the ice shaver, cover 2 is moved upwardly along slots 32 to provide an opening and, when cover 2 closes body member 1, the lower open end of cover 2 engages end wall 6 and end wall 10 of cover 2 engages and seats in the open end of body member or receptacle 1. Cover 2 and receptacle or body member 1 are so formed as to conjointly define an ice containing space which is circular in cross section.

Circular end wall 10 of cover 2 is formed with an opening 11 through which there extend a rotating shaft 16 and an externally threaded tube 14, the opening 11 being reinforced by an annular rib 12. Bushing 7, in receptacle or body member 1, is formed with an internal thread 13 threadedly engaging the external thread on tube 14. The upper end of tube 14 extends into opening 11 of end wall 10, and rotatable shaft 16, having handle 15 fixedly secured to its outer end, is movably telescoped into threaded tube 14. The thread 17 of tube 14 is a multiple thread and, in the particular embodiment illustrated, is a triple thread.

A substantially circular ice gripping plate 18 is secured to the lower or inner end of rotatable shaft 16 and retains threaded tube 14 against displacement. The handle 15 is fixedly secured to the upper or outer end of shaft 16 so as to rotate the shaft. A movable flange member 19 and a spring 20 are positioned between the outer end of threaded tube 14 and handle 15, and embrace the upper end of rotatable shaft 16. Flange member 19 slidingly engages shaft 16, and a flange surface 19' of flange 19 engages end 14' of externally threaded tube 14.

Spring 20, interposed between handle 15 and flange 19, presses flange surface 19 against tube end 14', so that the lower end of tube 14 presses ice gripping plate 18. Ice gripping plate 18 is fixedly secured to the lower end of shaft 16, and rotates with shaft 16 upon operation of handle 15.

Referring particularly to FIGS. 1, 2, 5, and 6, toothed metallic means 21, arranged at angular spacings of 90 degrees, are mounted in the outer face of ice gripping plate 18 to cut into a block of ice a, so that the ice block is rotated securely with plate 18.

In the operation of the ice shaving device shown in FIGS. 1 through 8, threaded tube 14, pressed between flange member 19 and ice gripping plate 18, generally follows the rotation of shaft 16. As tube 14 advances through bushing 7, upon rotation of handle 15, shaft 16 is also advanced. When the shaving is initiated as a block or cube of ice is engaged by the outer surface of holding plate 18 and pressed against ice shaver blade 5, rotating shaft 16 rotates in tube 14 to effect the shaving. During the shaving, tube 14 advances the shaft 16 by advancing itself in proportion to the decrease in the quantity of ice between plate 18 and blade 5. In other words, shaft 16 advances with a wider pitch before plate 18 engages the ice, and then moves forwardly, in accordance with the volume of ice remaining to be shaved after initiation of the shaving.

After completion of the shaving, the shaft 14 may be retracted by simply reversing the direction of rotation of handle 15. Another way of retracting shaft 14 is to slide cover 2 backwardly against the bias of spring 19, by pulling back on rib 12 of end wall tube 10 of cover 2, thus to disengage flange surface 19 from the end surface 14' of tube 14. As a result, retraction of cover 2 causes the now rotatable tube 14 to rotate backwardly through bushing 7 without accompanying rotation for shaft 16, as best seen in FIG. 8. Thus, there is no difficulty with retracting the shaft means responsive to retraction or opening of cover 2.

Referring now to FIGS. 9 and 10, in the embodiment of the invention illustrated therein the shaft rotating mechanism is essentially similar to that already described. An internally threaded bushing 23 is rotatably mounted in a bushing portion 31 of the body member, and is restrained against axial displacement in bushing portion 31. In this embodiment of the invention, rotating shaft 24 is formed with external threads 25 and is threaded through bushing 23. That is, bushing 23 can be freely rotated as an unit with shaft 24, so that the rotating movement is effected in the same way as with the previously shaft or rotating mechanism.

In the embodiment of the invention shown in FIGS. 9 and 10, bushing portion 31 is provided with an aperture or bore 33 into which there are inserted a friction piece 27 engaged by a spring 26. After insertion of piece 27 and spring 26,an adjusting screw 30 is threaded into bushing portion 31 to project upwardly therefrom. Friction piece 27 is engaged with the outer surface of rotatable bushing 23, and spring 26 is interposed between piece 27 and screw 30 and seated on both of these elements. By adjusting screw 30, both the friction resistance produced responsive to friction piece 27 engaging bushing 23, and the rotating force of bushing 23, can be adjusted.

Thus, when adjustment screw 30 is tightened, the friction resistance of friction piece 27 against bushing 23 increases and the slidingly rotating force of bushing 23 decreases. As adjustment screw 30 is loosened, the frictional resistance of bushing 23 becomesless. When the frictional resistance becomes negligible, bushing 23 is rotated as a unit with shaft 24.

Thus, by rotating handle 28, shaft 24 is rotated together with bushing 23. When frictional resistance is provided by compressing friction piece 27 against bushing 23 by tightening adjustment screw 20, rotation of bushing 23 is retarded and shaft 24 advances forwardly through the bushing. When a piece of ice engaged with ice gripping plate 29, engages ice shaver blade 5, shaft 24 effects shaving of the ice while bushing 23 rotates. The difference in the speed of rotation between shaft 24 and bushing 23 enables shaft 24 to advance in proportion to the decrease in the volume of the ice mass being shaved. In other words, shaft 24 advances with a pitch adjusted by rotating bushing 23, and not with the fixed pitch of its external thread 25.

In the present invention, the movement of the threaded tube, which advances in proportion to the volume of already shaved ice blocks or cubes, is transmitted to the rotating shaft during the shaving, so that the ice gripping plate advances with a pitch corresponding to the ice volume being shaved. As a result, ice shaving can be effected with a minimum of effort, contrary to the case with conventional devices operated by rotating a handle and pushing a shaft forwardly. In addition, after shaving is completed, the shaft means of the present invention can easily be rotated rearwardly by pulling back on the handle.

Furthermore, during opening of the cover, the shaft means is rotated backwardly in correspondence with the opening movement of the cover. In the position where the shaft means has been retracted, the threaded tube and the bushing are engaged with each other. Thus, the ice gripping plate is held in its retracted position and iceblocks or cubes can be placed in the device without manually holding the handle in the retracted position. Consequently, the new device is capable of very convenient operation. As mentioned, the increase of the tube pitch assures proper functioning of the de- 1 vice, so that the ice gripping plate can be retracted by fewer reverse rotations of the handle. An important feature of the invention is that the threaded tube and the bushing arrangement can be manufactured easily and economically.

The container of the device comprises the receptacle or body member and cover, both of which are elongated and substantially semi-circular in section, the body portion and the cover being slidably engaged with each other. The ends of the body portion or receptacle and of the cover are so formed as to define an ice containing space which is circular-in cross-section and in the interior of which are located the rotating shaft means, the ice gripping plate and the shaving plate. Consequently, the device of the invention is capable of shaving not only ice blocks, but also ice chips.

The invention device facilitates clean shaving without entry of foreign matter into the ice containing space, and is very attractive in external design. In addition, the device of the invention can effect shaving of ice blocks in a variety of sizes of shaved ice, inasmuch as the ice shaver blade is easily adjustable with respect to its projection into the ice containing space by simply adjusting the holding bolt therefor.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
