Ion-SHAVING MACHINE.

Application filed June 22j, 1925. Serial No. 38,670.

This invention relates to ice shaving or grinding machines adapted for use by confecioners in making iced confections.

A confection consisting of ground or shaved ice placed in a paper cone and then flavored by saturating the ice with a flavoring syrup has been favorably received by the public. Prior to my invention the ground ice for these cones was obtained by scraping a small toothed device over a block of ice until a suicient quantity of shavings was accumulated to lill a cone. This process necessitating considerable labor and time wasdeemed unsatisfactory. Therefore, it is the principal object of the present invention to provide agenerally improved machine capable of operation to reduce ice to finely divided particles and to dispense the same in desired quantities into cones.

In carrying out this object, I provide a feed hopper which is contiguous to a grinding cyllnder wherein blades and a feeding device cooperate to reduce pieces of ice into finely divided particles. These particles are discharged into a dispenser which is adapted to receive the end of a cone. A plunger operates in the dispenser to transfer particles of ice from the dispenser to the cone.

One form which the invention may assume is exemplified in the following description and illustrated by wayof example in the accompanying drawings, in which:

Fig. 1 is a view in central vertical section of a device embodying the present forml of the invention.

Fig. 2 is an end elevation of the same.

Fig. 3 is a fragmentary view in plan section taken on line 3-3 of Fig. l.

Referring more particularly to the accompanying drawings, 10 indicates a supporting base which is adapted to be secured to a p counter or the like for supporting the machine in an operative position Bolted or otherwise secured to the base 10 is the body p portion 11 of the machine.

This body portion 11 includes a hopper 12 which is formed with an open mouth 14 and a concave wall 15 that constitutes both the rear and bottom wall of the hopper. Adjacent the hopper a grinding or shaving chamber 16 is formed. This chamber 16 is cylindrical and horizontally disposed in a plane relative to the hopper so that ice fed into the hopper w1ll be directed by its concave wall 15 into the grinding chamber 16.

As it will be noticed in the drawings the plates 19 are secured to the end of the' cylinder 1.6 and abut against the outer end of the grinding, disk to removably hold it 1n place.

The grinding disk is formed with dia.- metrically opposed radial slots 20 which are vertically disposed. Contiguous to one edge 'of each slot, at the outer face of the disk, an oblique surface 21 is formed for recelvmg cutting or shaving blades 22.` Screws 23 are projected through slotted openmgs 24 in the bladesand threaded into the disk to secure the blades against the oblique surfaces referred to, with the cutting edges of the blades projecting inwardly from the inner face of the disk. As `the openings 24 in the blades are slotted, the distance with which the blades project from the inner face of the disk may be adjusted. As the surfaces upon which the blades `are secured are Oblique and oppositely disposed, the cutting edges of the blades will be directed at opposite angles. Therefore when pieces of ice to be ground are force 1n a circular path over the face of the disk, both blades will be effective in shaving or cutting the ice. The shavings or cuttings will be dire'cted by the obliquely disposed blades through the slots 20 into a disenser 26. Y

the disk and cause it to move in a circular ath thereo'ver, I provide a helical feeding blade 27 which is disposed concentrically within the chamber 16 and which is of a diameter but slightly less than this chamber. This helical feeding blade 27 is secured on' a shaft 28 which is horizontally disposed and journalled at its opposite ends in the hopper 12 and in the cutting disk 17. This shaft 28 is collared to prevent it from moving axially.

To revolve the shaft 28 and consequently the feed blade 27, the outer end of the shaft is fitted with a fly wheel 29 having a handle To force the ice against the inner face of l a circular path over Ithe cutting edges of the4 blades. During such movement thecutting e edges of the blades will shave cuttings from the ice and cause them to discharge through the slots 20 into the dis enser 26.

The dispenser 26 is cy indrical end vertically disposed and centrally located with respect to the vertical axis of the disk 17, and is secured to the outer face thereof by screws. The wall of the dispenser which abuts against the cuttin disk is formed with a vertical opening w ich is in alignment with the slots 20 formed in the disk so' that the cuttings passing through the slots 20 will discharge into the dispenser 26. The lower end of the dispenser 1s open and flared so that a cone may be yieldingly held therein as shown in dotted lines in Fig. 1. The upper end of the dis enser 26 is fitted with a frusto-conical p unger 31 having a vertical rod 32 which projects upwardl through and is guided into the upper end o the dispenser 26. The outer end of the plunger rod 32 is formed with a knob 33 by which the plunger may be actuated. A compression spring 34 I of ice is broken u is interposed between the under side of this knob and the upper end of the dispenser 26 and normally tends to maintain the plunger 31 in its u permost position.

It is o vious that by depressing the plunger 31 through the medium of the rod 32 and the knob 33, the plunger will move downwardly in the chamber 25 and discharge an ice cuttings therein through its lower In actual operation of the device, a block into small pieces which are deposited in t e hopper 12. A cone is then inserted into the lower end of the dispensing device 26. By revolving the ily wheel 29 by means-of the handle 30 the helical feeding blade 27 will be revolved and will feed the pieces of ice fed into the ho r toward the blades. This will cause t e ltter to shave or grind the ice and to deliver the ground particles or shavings into the dispenser 26.

When suilicient shavin or ground particles have been accumu ated in the dispenser, the plunger 31 is depressed to force the ground particles or shavings into the cone held at the lower end of the dispenser. As the plunger 31 is frusto-conical the upper end of the ice packed in the cone will be conical and of neat appearance. The cone of the round ice therein may then be removed rom the dispenser and impregnated with a avoring syrup.

It should be stated that a gauge slot 35 is When. it is desired to cleanse the machine,

it is only necessary to remove the small locking plates and remove the disk 17 and the dispenser 26. All the parts of the machine willttshen be exposed for cleansing or adjustmen From the foregoing it is obvious that a very simple and eicient machine is provided by which ice may be rapidly ground to provide so-called snow for ice confections of all descriptions.

While I haveA shown the preferred form of my invention, it is to be understood that various changes in 'its construction may be made by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.
