ICE-SHAVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 753,161, dated February 23, 1904.

Application filed May 12, 1902. Serial No. 106,906. (No model.)

To all whmn it may concern.-

Be it known that I, FRANK J. REINHOLD, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Ice-Shaving Machines; and I declare the following tobe a full, clear, and ex.- act description of the invention, such as will enable others skilled in the art to which it pertains to make use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to ice-shaving machines, and has for its objectan improved machine intended to cut or shave ice into small pieces.

In the drawings, Figure l is a front elevation of a machine embodying the invention. Fig. 2 is a longitudinal vertical section of such a machine. Fig. 3 is a front elevation of a machine arranged to be attached to a wall. Fig. 4 is a detail of the knife on an enlarged scale. Fig. 5 is a front elevation of the detail shown in Fig. 4:.

In the machine shown in Figs. 1 and 9/ the shaving-knife is given a vertical reciprooatory motion.

In the machine shown in Fig. 3 the knife is given an oscillatory or swinging motion.

A indicates the framework, supporting an oblique table 2, on which the ice block 3 rests. At the bottom end of the oblique table and at the front part of the frame are vertical posts 4: and 5, in which engages a vertically-sliding plate 6, preferably formed as a grating or grid-plate. This is held by guides in the posts 4: and 5 and is actuated by a lever 7, that is pivoted on the journal 8 and supported on the post 5. Thelever 7 is a bent lever, and from its angle 9 extends a link 10, that is pivoted to the lever 7 and to the sliding plate 6. The oscillation of the lever 7 reciprocates the plate 6 vertically in its ways onthe posts 4 and 5. The plate 6 prevents the ice block 3 from escaping from the table 2; but the block slides down on the surface of the table 2. with its advancing face in contact with the plate 6. On the plate 6 are two brackets 11, in which are screwed holding-bolts 12, and these bolts hold an adjustable plate 13 to the brackets. The plate 13 is made with oblong holes through it, and bolts 12 engage through the holes.

The plate is provided with a flange 14, that overhangs the upper side of the brackets 11, and through the flange 14 are adjusting-screws 15, arranged to regulate the position of the plate 13 on the brackets. To the front or lower edge of the plate 13, underneath an overhanging flange 16, is secured a serrated or many-pointed knife 17. The knife is held on pins 18, and there is a spring 19 interposed between the back of the knife and the flange 16. The points of the knife extend through a throat20 in the plate 6, and the distance to which they extend may be adjusted by the screw 15. The throat is wide enough to allow the points of the knife 17 to swing outward, so that the extreme points are substantially in that surface of the plate 6 which lies toward the ice block. Normally the springs hold the knife with its points lying some distance inside toward the ice from the face of the plate 6, and on the downstroke the pressure against the knife or the resistance to the downward travel of the knife caused by the engagement of the point of the knife with the ice tends to force the point of the knife upward and inward, causing it to out to the full depth to which it is adjusted. On the upstroke, however, the knife yields and is easily lifted above the ice. In action the ice is carried by gravity downward, resting always against the plate 6 in position to furnish the full feed for the cut of the knife. A counterweight 21 aids the operator in lifting the plate 6.

In the form shown in Fig. 3 the ice is fed to the knife down a trough-shaped receptacle 22, and the plate 60 in this case instead of engaging in vertical ways swings on the pivot 23, which is holder and guide for both the plate 60 and the lever 0. 4

The entire device is secured by bracket 25 to the wall; but the action is similar in all respects to that of themachine shown in Figs. 1 and 2.

What I claim is 1. In an ice-shaving machine in combination with a table arranged to hold a block of ice and to cause the same to feed by gravity, a plate arranged to engage against the front of the ice and provided with an opening for of ice thereon by gravity, a reciprocatory knife-carrying plate arranged as a stop to the ice block and provided with an opening for the reception of a knife, a knife, and means for supporting said -knife yieldingly in a position slanting to the direction of movement of the plate, with the cutting edge of said knife protruding through said opening.

In testimony whereof I sign this specification in the presence of two witnesses.

FRANK J. REINHOLD.
