FEEDING MECHANISM FOR ICE-SI'IAVING MACHINES.

Specicaton of Letters Patent.

Patented Dec. 31,1912.

Application filed July 24, 1911. Serial No. 640,272.

To all 'whom t may concern.'

Be it known that I, Hanny SMITH, a citi- Zen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented a new and useful Feeding Mechanism for lee-Shaving Machines, of which the following is a specification.

The present invention relates to improvements in a feeding mechanism for ice shaving machines, the primary object. of the invention being the provision of a novelI forni of mechanical movement, whereby the ice retaining disk is properly rotated and fed to exert the desired pressure upon the ice during the shaving thereof and whereby the said disk after having reached its lowernlost position willbe readily released from the operating mechanism so as to be lifted or have imparted thereto, a sliding movement so that the disk may be lifted away from the cutting knives and a block of ice inserted therebetween.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood th-at changes in the precise embodiment of the invent-ion herein disclosed can be made within the scope of what is claimed without depart-ing fro-m the spirit of the invention.

In the drawings z-Figure 1 is a side elevation of the machine in operable positioii. Fig. 2 is a vertical section taken o n line 2 2 of Fig. 1. Fig. 3 is a top plan view of the machine. Figs. 1 and 5 are detail views of various elements of the machine on an enlarged scale.

Referring to the drawings, the numeral. 1 designates the supporting plate having an integral arm or bracket 2, whereby the cylindrical ice receptacle or hopper 3 may be properly attached for operation. In the wall of the receptacle is provided an ice inserting opening 1, which is closed by the door or closure 5, the eyed lugs G and 7 of the receptacle and the pin 8, forming a hinged connection between the door and receptacle, while the slotted lug 9, at the other side of the door 5, is adapted to register with the clamping screw 10, pivoted to the lug 11 of the receptacle to clamp the door in closed position.

The bottom 12 of the ice receptacle is provided with a slot or aperture 13, which acts as a shaved ice discharge for the receptacle, and although only one is here illustrated, it is understood that any uumber may be employed, and may be arranged diametrically, or radially, as desired. At the far side of the outlet is a shouldered rib 14 whose face inclines and has removably attached thereto the shaving blade 15, whose cutting edge 1G is disposed to project within the receptacle slightly above the bottom thereof into ice engaging position. so that as the block of ice is rotated, as will presently appear, the blade 15 will shave ine same and conduct the shavings through the outlet.

Formed integral. with the top 3 of the icc hopper or receptacle is an arm or lug 17, carrying the journal box 18, for the reception of the horizontal spindle or operating shaft 18, which carries upon its outer end the balance wheel 20 and the operating crank handle 21. If so desired, a fast and a loose pulley may be mounted upon the sha ft 19, so that the machine may be operated by power'.

Upon the inner end of the Shaft 19, is keyed the small pinion 22, which meshes with the large bevel pinion 23, which is rotatably mounted upon the vertically disposed main spindle or shaft 24, the bevel pinion and shaft being provided with cooperating key and key-way 25, by means of which the rotation of the bevel pinion 2S will impart to the spindle or shaft 2-1 a rotary movement, so that the circular disk or follower 26, carried upon the lower cud of the spindle of shaft 21 within the receptacle 3, and havingthe ice engaging prongs or teeth 27 upon its underface will impart to the block of ice therebelow a rotary ac tion, so that the lower surface thereof in engagement with the blade 15 will be shaved.

The spindle or shaft 24 is provided with the screw threads 28 intermediate of its ends, and at its upper end with the loop or eye 29, by means of which the spindle and follower may be manually raised, instead of necessitating the reversalof the rotation of the shaft 19 to lift the follower. To accomplish this, and also to cause the spindle 24|: to be fed or moved downwardly and carry the follower therewith to compensate for thc shavingl taken from the ice, and to thereby at all times hold the block of ice in proper frictional contact with the blade15,

a split interiorly threaded boss 30 is mounted above the bevel gear 23, and normally has its threads in mesh with the threads 28 of the spindle 24, the rotation o-f the said spindle, causing the threads 28 to turn within the stationary boss 30, so that the spindle 2li and follower are moved downwardly gradually during the shaving operation. As above stated this boss is split and formed into sections a and '6, each one of which is provided with a pin 3l, slidably mo-unted in its respective cam slot 32, formed in the frame or cap 33, having the handle 34 and fitting loosely about the spindle 24, whereby the manipulation of said handle will actuate the pins to cause the said sections a and I) to separate to disengage the threads 28 of the spindle 24, to permit the operator to grip the loop 29 and lift the spindle 24 and the follower to allow the ice to be inserted into the hopper through the opening t. As shown in Figs. l and 5, the lower rim c of the cap is turned in to iit in the circumferential recess or groove Z formed in the sections a and Z), so that the said cap is held by and relatively holds said sections in operable position. In order to adjust the locking device a set screw 35 is employed. The combined casing and frame 37 supports the split locking device or boss 30, and protects the working parts, being carried by the top of the receptacle.

F rom the foregoing description taken in connection with the drawings, it is evident that a machine which retains the block of ice resting upon the cutter or shaver is provided, and that by reason of the peculiar construction of operating mechanism the follower is actuated to rotate the ice during the shaving thereof, and at the same time be given a downward movement to valways retain the block of ice at the desired pressure upon the shaving blade, a locking device being provided to permit the follower to be slid to its upmost position and held there byl said device while the receptacle is being relled with ice.

Vhat is claimed, is:-

l. In a mechanism of this character, a support, a vertically disposed rotatable eX- teriorly threaded spindle mounted in the support and provided with a longitudinal groove throughout the length of the threaded portion thereof, a rotatable gear provided with a smooth bore mounted upon the spindle and having a key entering the groove thereof to impart rotation to the spindle, means for rotating the gear, a sectional disk surrounding the stem above the gear and provided with threaded portions to coact with the threads of the spindle to impart to the spindle a downward motion during the rotation thereof, said disk being provided with a circumferential groove, a cap surrounding said disk and having an inturned rim mounted in the groove of the disk, means for oscillating said cap, and c0- acting means carried by the sections of the disk and the cap for imparting to said sections movements into and out of engagement with the threaded portion of the spindle when said cap is oscillated.

2. In a mechanism of this character, a support and a vertically disposed rotatable eXteriorly threaded spindle slidable in the support and provided with a longitudinal groove throughout the length of the threaded portion thereof, a rotatable gear provided with a smooth bore mounted upon the spindle above the support and having a key entering t-he groove thereof to impart rotation to the spindle, a casing carried by the support and covering the gear, means for rotating the gear, a sectional disk surrounding the stem and carried by the casing above the gear, said sectional disk being provided with threaded portions to coact with the threads of the spindle to impart to the spindle a downward motion during the rotation of the spindle, said disk being provided with a circumferential groove, a cap of greater diameter than the disk surrounding said disk and having an inturned rim mounted in the groove of the disk, means for oscillating said cap, said cap being provided with two cam slots through the top thereof, and a pin connectedto each section of the disk and passing through its respective slot of the cap whereby when the cap is oscillated the sections are moved to and from the spindle within the cap.

3. yIn a mechanism of this character, a support, a horizontal bearing carried by the support, a power shaft journaled therein, a casing carried by the support and about the inner end of the shaft, a vertical shaft projecting through said casing and support, said shaft being eXteriorly threaded and having a key way longitudinally thereof, a gear mounted in the casing above the sup'- port and about theV vertical shaft, said gear having a key to fit in the key way of the vertical shaft, said gear being operably connected to the horizontal shaft, a pair of separable thread engaging members carried by the casing and about the shaft, and means for moving said sections into and out of engagement with the threads of the shaft.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
