, To, all whom it may concern:

Be it known that I, DANIEL L; HOLDEN, a citizen of the United States, residing at New York, in the borough of Manhattan, county of New York, and Stte of New York, have invented ,certainnew and useful Improvements 1n Vertical Ice-Machines; and I do hereb declare the following to be a full, clear, an' exact descri tion of the invention, such as will enable ot are skilled in the art to which it appertains to make and use the same. 1 Y This invention relates to. improvements in ice manufacturing machines for the prorapid rate, and w erein are introduced the necessar means to promote rapid freezing, and rapid and thorough removal of the ice coating in small particles which are floated above the clear water,for removal to ice presses where the particles are consolidated into convenient sized merchantable blocks. a

The invention is illustrated in the accompanying drawings, in which Flgure 1 is a general vertical central section, although some of the minor parts are not in section Fig. 2 isa to view, the hood and cover being removed; ig. 3 is a plan of one'of the drivingarms showing the man-.

ner of attachinv the arms to the hollow vertical driving shaft, and the guide attachments; Fig; 4 is an elevation of Fig. 3; Fig. 5 is a fragmentary elevation of a guide, its

, holder, cutter-bar and cutter holder; Fig. 6

holder; Fig. 7 is a plan of a cutter holder, and cutter with a cutter bar in section, and a section of the freezing cylinder, showing their relative positions; F1 8 is a plan of the guide and cutter barho der; Fig. 9 is a fragmentary elevation of a cutter bar showing a cutter seat. I I 7 Similar characters of reference indicatethc same parts wherever used. I I I Upon a suitable foundation 1 are'erected columns 2 whichsupport a bed plate 3, at sufficient height to ermit convenient entrance thereunder. Kiouhted upon and secured to the bed plate is a central or clear water tank 4, shown as made in two parts, as

a mere matter of convenience in manufacturing, and when somade the separable parts clear of the guides 40, 4h.

are tightly secured together asone entire'tank. Bed plate 3 has a central raised hub 5 above a recess 6, and on, the hubs upper end is carried a hollow vertical driving shaft 7.

which passesupward to near the top of tank 4 4, and downward through and guided by hub 5to some distance below bed late 3, a

stuffing box 8 being formed aroun shaft 7 in hub 5 and provided'with a follower or gland 9 to prevent any leakage from tank 4 at the 'unction of the hub and shaft.- An upper ui e has a series of legs 10 joined to a central ub 11, and it guides the top of shaft 7.

Shaft 7 has a bevel gear. 12 secured .to its lower end, and it is driven by a bevel pinion 13 on a horizontal shaft 14 carried in hangers 15, 16, secured to the bed late 3, and the shaft'has a pulley 17 throng 1 which 'the power is transmitted to the shaft.

the outer end of each arm a guide seat 30 is formed and a cap 31 is attached to close the outer side andsecure the guide.

Opposite the outer ends of horizontal arms 20 to23 and 24 to 27 are square depending cutter bars 32, 33,34, 35, placed to have two corners of the square on a radial line of the tank, and two corners on a circumferential lineythus putting the bar in position for the most effective resistance to the pressure brought to'bear against it, and atthe same "time presenting a section easily secured from turning. 'Cutter bars 32 to 35 have secured thereto cutter holders 36, 37 38, 39 and to 40, 41, and the bars have also securedthereto intermediate cutter holders 42, 43 which are Each holder has a cap 44 to secure a cutter 45 to the holder and notches 46 are also formed in each cutter 100 bar wherein the cutters are inserted to secure the cutters, their holders and caps in vertical position (see Figs. 5 to 9 ine. The cutter ars are free to move up and down in tank 'these cutter holders are also secured guides I 4, by means of the guides 40, 41, and are suspended by links 47, 48, 49, 50 to leverarms '51, 52, 53, 54 fulcrumed on arms 55,

i and to'be carried up and down by a vertically actuated and non-revolving sleeve 61 which at its lower end is inserted within the up end of shaft 7, and at its'upper end is gu1 ed freely up and down throughhubf'll of the upper guide but is prevented from rotary movementby a spline 62. Astuffing box 63 is formed in the upper end of shaft 7, and is provided with a gland 64, to revent water en-terin the interior of sha t 7 Within shaft 7 18 another shaft 65 having a collar 66 at its lower end which rests upon a nut 67 screwed into shaft 7 and having a hole therethrough for the passing of {shaft 65 and below the nut is a gear 68 on the shaft driven by a gear 69 on a horizontal shaft 70 supported in hangers 71, 72 and provided with tight pulleys 73, 74 and a "loose pulley. 75. At the upperv end of shaft 65 it is provided with a screw 95 ntering sleeve 61, which acts as a non-rotdtable nut, and moves up and down as the screw is turned to the right or left. -Means for the spiral movement of cutters 45 within tank 4 are provided, as follows, to enable the narrow cutters to traversetheentire inner surface of the tank, upward and downward and thereby cleanioff the ice coating, in alternate courses. The shaft 70 Y is provide 'with a screw 76 on which is a back and forth.

traveler which is moved back and forth by the screw, and is itself reventc'dfrom rotary movement. .Sccured to traveler 77 is a lifting loop 83. which surrounds a lever 82 and is the means by which the lever is thrown Lever 82 has a counterweight 84 at itstop, and at its bottom end it is bifurcated, with each jaw 85 circular sha ed at the edge, and passing by the sides of s lifter rod-86 which is su ortcd in pendants from hangers171, 72. ilpon rod 86' are adjustable collars 88,89 against which jaws -85 alternately abut, and also shifter fingers 90 which extend upwardly and guide strai ht belt 91 and crossed belt 92 whichpass e-.

tween them from the source of power. Collars 93, 94, adjustablealong rod 86 limit its movement.

The reversing means hereindescribed is the subject ofa separate application, but its description is deemed necessary at this point to give a clearunderstanding of'the operation of the machine.

A conical dome97 surmoun'ts tank 4, and at its apex is attached a delivery pipe 98' leading to a pump (not shown) by which the ice-particles 99'are passed to the presses (not shown). A sweep 100 is, mounted above minute.

arm 55 and is supported by a rod 100' to remove adhering. ice particles which maylodge under arms 10. A sweep 101 is attached to rod 102 secured in '-screw,95 and passing outward and upward through cap 96 which closes the top of shaft 7 and is provided with a stufling box, and is the meansto remove.

ice particles which may adhere to the inside of dome 97. A float trap 103 of any suitable;

construction is mounted on standards 10 4,

inlet ipe 106 is attached, it being opened and c osed by. float 107, the trap having a.

. '75 above dome 97, and thereto a clear water pipe 108 in communication with the top, of

dome 97 and 1pi )e.1 ()9 in communication with tank 4. ater will enter trap 103 by pipe 106 and flow to tank4 by pipe 109, but

raise float the inflow.

Surrounding tank 4 is a'freezing tank 1'10,

.in which are introduced a series ,of coil pipes 1 11, 112, 1 13, 114, encircling tank 4 fromtop to bottom, they are charged with anhydrous ammonia from an inlet pipe 115, and valves 116, 117, 118, 119 are provided to regulate the. supply. The'supports for these coils are not shown, asany form, that is suitable may a be used, and their showing would tend to obscure the other parts sho.wn. The outlet of the coils is at one side of the bottom of tank 110, preferably at the side opposite to the inlet, and the passage therefrom to an ammonia pump is not illustrated, as it can readily be understood. Tank has a covering 120 and is filled with chlorid-calciumsohtion, except for a space 121. at the bottom which is filled with an insulating material to prevent freezing at the bottom of tank'4.v A pump-122 rests onloundation 1, has suitable means for its driving, and therefrom 123 communicates with one side of the ot tom of the tank 110,-and a pipe 124 communic'ates with the opposite side, so that by neansof the pump there is a continuous circulation of I the material surrounding the coils. A pipe 125 is attached to bed latev 3,

and is controlled by any suitable va ve 126 and is the means for discharging the water from tank 4 whenever it, is necessary to make repairs, to adjust cutters, or an entrance to the tank is necessary. Shields 127 arc'attachcd tocuttcr holders36, 37, 38,. 39, 42,

43, and are curved to thcta'pcr end of cut:

ters 45 (see Fig.2) and are employed to prevent the lodging of the ice particles against" the cutter holders.

The operation of my mechanism is as follows: Power is applied to the pulley 17 and thereby its shaft 14, gears 12, 13 and shaft 7' are rotated at aspced of about four turns per then be rotated .as' will also cutter bars 32 to Arms 20 to 23 and 24 to 27 will been filled with purified water, an tank 110 with chlorid calciumsolution and the coils 111 to 114 with anhydrous ammonia.

By reference to-Fig. 1 it will be seen that the depending arms or cutter bars 32 and 34 are at different distances or elevations above bed plate 3, and it must also be understood that cutter bar 33 between 32 and 34, (not shown in Fig. 1 but seen in the background in Fig. 2) is elevated at a distaneemidway between cutter bars 32, 34, and that'cutter bar 35 between 34 and 32 (not shown inTig. 1 but seen in-the foreground inFig. 2) is also elevated as much above bar 34 as bar 33 is above 32 and as'much as bar '34 is above 33.

Another way to understand the relative elevations of the depending-arms or cutter bars to each other, and to the bed plate 3,

, edges and there wouldbe anintervening belt plied to and the cutters and their holders on each vbar, relative to the cutters on every other cutter bar, will be to commence at cutter;

bar 3 2- and go around the tank 4 until we again come to bar 32. Bar 32 (and every otherbar) has a lower cutter holder 36, and

all of the cutters and holders on each bar are arranged alike, as seen in Fig. 1 at equal dis tances apart; there are four cutter bars, and holder 36 and its cutter other 33 are above holder 36 of bar 32 one fourth of the distance between holders 36, 42 of bar 32; bar34 and its holders one fourth above bar 33 and. its holdersjbar 35 one fourth above bar 34 and its holders, andwhen reaching bar 32 again its holder 42 is one fourth above holder 36 of bar 35, so that the bars with their holders and cutters are relatively in successive steps of elevation equal to one fourth of the (11stance between the cutters and holders of an adjacent bar. This different elevation of the bars is done hy fnaking links 47 to 50 of different and suitable lengths for the pur w pose.

If as now described thebars and cutters are rotated within the tank 4 the.cutters would each chip off the ice ina horizontal plane and of a width equal to their cutting of unchipped ice between each cutter, as the cutters to be effective for the most perfect work must be quite narrow at their cutting edge. To overcome this defect and clean off every particle of the ice it is essential that Wl11l6 the cutters pass around the tank they must also be caused to traverse up and down to clean off the: intervening belts, and means are provided for this purpose. hen pulley 17 commences to move and to move all its attached parts,-the power is also ap- 68, 69, s aft and. its screw 95 in direction to pull down sleeve 61 which will be seen in Fig. 1 by means of collar 60, links 47. to 50 and levers :51 to 54 elevate cutter bars 32 to 35 and 'theirattached cutters 45 which will w out an upwardly tending spiral path,

alternately.-

pulley 73 and rotates shaft gears and as the screw 95 gains one thread for each complete rotation of the cutters within tank 4 it will be evident that'when they have passed. around the tank enough times to remove the intervening belts of ice that the whole interior coating of ice will have been removed in. broken particles and have floated to dome 97 for removal .to the presses.

While the above operation was in progress thescrew 76 was moving traveler 77 and its loop83 to elevate lever 82 and its counterweight84, so that when the cutters 45 had completed their spiral courses the lever 82 and its counterweight passed the perpendicular line and /fell -by gravitation to the opposite end of loo 83 and in doing so automatically abutte collar 88 moved rod 86 and. fingers 90 to shift crossed belt 92 to pulley 74, and straight belt 91 to loose pulley 75, thus reversing screw 95 and allattached parts and --carrying cutters 45 downward over the space heretofore upwardly traversed, and which -nieantime has become freshly coated with ice. So the operation goes on, the cutters traveling in spiral courses-alternately upward and downward. The mechanism can readily be constructed to other proportions so that the number of upward and downward courses of the cutters may be increased or diminished, as well as the number of cutters in use on each arm, or

the number 'of arms.
