Application filed October 5, 1914. Serial No. 865,170.

To all whom it may concern: V

Be it known that I, ALFONS MosoA, a citi- Zen of the United States, residing at Norfolk, in the county of Norfolk, State of Virginia, have invented certain new and useful Improvements in Ice-Shaving Machines; and I do hereby 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;

This invention relates to ice shaving inachines and particularly to a type adapted for finely shaving ice for use at soda fountains andthe like.

The object of the invention resides in the provision of a machine of the character named embodying improved constructionwhereby the operation of same is rendered rapid and effective and machines of this 7 type simplified.

lvith the above and other objects in view the invention consists in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in 'which Figure 1 is a plan view of an ice shaving machine constructed in accordance with the invention;

Fig. 2, a side'view of what is shown Fig. 1;

Fig. 3, a section on the line 3-3 of Fig. 2;

Fig. 4, an end view ofthe machine;

Fig. 5, a partial longitudinal section;

Fig. 6, a section on the line 66 of Fig.

Fig. 7, a section on the line 77 of Fig. 2;

Fig. 8, a section on the line 8-8 of Fig. 1, and

- Fig. 9, a view in elevation of the thread block.

Referring to the drawings the improved ice shaving machine is shown as comprising a casing A formed of a bottom section 10 supported upon legs 11 and a top sect1on 12 hinged to the bottom section at one side edgeand provided with ahandle 13 whereby said top section may-be raised to afford ac- "cess to the interior of the casing for the purpose of filling the latter with ice. One end a of the casing A is closed by ahead 14 having a depending discharge mouth 15 through which latter the shaved ice is delivered into a suitable receptacle. The outer side of the lower end of said discharge spout embodies a separate plate 15 hinged at 16 and de tachably fastened at 17 whereby access to the interior of the spout may be readily had for adjustment of the knives to be presently referred to.-

Rotatably mounted in the center of the head 14 is a shaft 16 which has fixed on the inner end thereof a knife disk B upon which is mounted ina suitable manner a plurality ofradially disposed knives 17, the disk B being provided with openings 18 through which the knives 18' project respectively. The disk B is further provided with an extended hub portion 19 having arms 20 and secured to the disk B in radial alinement with one or" the arms 20 is a wing 21 adapted to sweep the interior of the head 14 during the rotation of the disk B. The periphery of the disk B is provided with teeth 22 for a purpose that will presently appear, the casing A being provided with an opening in its side wallat a given point through which a gear 23 projects, the teeth of the latter meshing with the teeth 22. The gear 23 is'fiXed upon a shaft 24 journaled in a bearing 25 formed integral with the head 14. Also fixed uponthe shaft 24 at the end thereofopposite the gear 23 is a gear 26which meshes with a gear 27 attached to a spindle 28 which latter is rotatably mounted upon a. stub shaft 29 carried by the head 14. The spindle 28 is adapted to be rotated in any suitable manner, either by hand or by suit- I able connection with a source of power.

Projecting laterally from the head 14 is a bearing 30, while another bearing 31 pro-. jects laterallyfrom the opposite end of the casing A and alines with the bearingv 30. These

bearings

30 and 31 support the terminals of a tubular member32 which is provided on its under side .with a longitudinal slot 33. Disposed within the tubular member 32 and rotatably mounted in the

bearings

30 and 31 is a screw 34 the purpose of which will presently appear. Fixed on the end of the screw' 34 adjacent the head 14 is a sprocket wheel 35 which alines with a sprocket wheel 36 fixed on the shaft 16, and traveling on the

sprocket wheels

35 and 36 is a sprocket'chain 37 whereby the rotation i sleeve 43 is a controlling handle 52 end of'which latter is secured to the 3S and the other end thereof to a fixed part 10. The disk 38 is provided with a lateral extension 11 which projects through a slot 42 in the casing A and in which slot the extension i1 travels during movement of the disk ihe free end of the extension n terminates in a sleeve 13 slidable on the tubular member This sleeve 13 has an opening le in the bottom thereof which registers with the slot 33 in the member 32, said opening 1% being surrounded by a skirt t5. h'lovably mounted in the opening 14; is a screw block 16, having a depending portion 17. This depending portion 17 is provided in its'outer face with a groove d7 in which is slidably mounted one arm of an 'L-shaped member 4:8, said arm having threaded therein a bolt 49 which projects through a slot 50 in the depending portion 17. Also threaded on the bolt 19 is a nut 51 which bears against the inner side of the portion at and whereby the L-shaped member 4-8 may be clamped to the portion d7 in a desired adjustment. The other arm of the L-shaped member carries an adjusting screw 52 which is adapted to engage the bottom edge of the portion 47 to limit the upward movement of the L-shaped member during adjustment of the latter relative to the portion $7. The bolt 19 also extends through a slot d9 in a depending arm 50 formed integral with the sleeve d3. The screw block %6 is normally held out of operative relation to the screw 3 1 by means of a spring 51 mounted in the slot 49 and bearing at its lower end against the bolt 4:9 and at its upper end against an end wall of the slot 19. Pivoted against the outer side of the with a bottom extension 53 which overlies the arm 50. This extension 53 is provided with a slot 5 1 through which the bolt 49 also projects. The slot 54 is so shaped that when the upper portion of the handle 52 is moved to its limit away from the head 1% the wall of the slot 5e will coiiperate with the bolt i9 to move the thread block 46 into operative engagement with the screw 34: and

thus connect the sleeve as with said screw 7 so that the rotation of the latter will move the disk 38 toward the disk B and force the ice disposed between said disks against the disk B to be operated upon by the knives 17-; Then the upper portion of the handle 52 is moved a predetermined distance to ward the head 1% the bolt 49, owing to the.

shape of the slot 5%, is released to the indisk 1 In order provided fluence of the spring 51 and the'thread block act and return the disk 38 to the limit of its movement away from the disk B.

.lnorder to automatically effect the disengagement of the screw block 46 from the screw when the disk 38 has moved-apre determined distance toward the disk B there is formed on the bearing 25 an extension 55 in which is adjustablythreaded a tripping member 56 adapted during the forward movement of the disk 38 to engage the .extension 53 of the handle 52 and rock said handle to effect disengagement of the thread block i6 from the screw 34; in the manner previously described.

to hold the disk 38: at the limit of its movement toward the disk 13 against the influence of the spring 39 so that small pieces of ice, if any, can be cleared away there is mounted on the head 14: a spring latch 57 adapted to engage over a nib 58 on the sleeve s3 just as the thread block 16 is disengaged from the screw 3%. By tripping the latch- 57 it will be obvious that the disk 38 can be returned to the limit of its movement away from the disk B under the influence ofthe spring 39, r

In order to hold the ice against the action of the knives 17 there is mounted upon the inner wall of the casing A a longitudinal wing 59 which slides, in a recess 60 formed in the disk-38.

Assuming the disk 38 to be at the limit of its movement away from the disk 13 a desired supply of ice to be shaved is deposited in the casing A between the disks 38 and B. This disk 13 is then rotated'in the manner previously referred to which will result in rotation ofthe screw The handle 52 is then operated to engage the thread block 16 withthe screw 3% when the disk 38 will be fed toward the disk 13 and the ice forced into engagement with the knives 17. hen the disk 38 almost reaches the knives 17 the extension 53 willybe engaged by the member '56 and the' thread block as disengaged from the screw-34:. At

the same time that this takes place the latch 57 will engage over the nib 58. Upon'tripping the latch 57 the disk 38 will be moved wear of the thread block 46.

What is claimed is 1. In a device of the class describedthe combination of a frame, a threaded shaft;

rotatably mounted onv the frame, a member mounted for movement longitudinally-cf the shaft, a thread block slidably mounted onthe member for movementlinto and out of engagement with the threads of the shaft,

it will be apparent that -the bolt,

spring means normally holding the thread block out of engagement with the threads of the shaft, a lever pivoted on the member, connections between the lever and the thread block whereby the movement of said lever in one direction will operate the thread block into engagement with the threads on the shaft to effect movement of the member longitudinally of the shaft, and means on the frame for engaging the lever when the member has moved a predetermined distance to rock said lever in the opposite direction and release the thread block to the influence of said spring means.
