Application filed August 18, I911. florlal No. 644,767.

. To all whom it may concern:

Be it known that I, DANIEL L. HoLunN a 'citizen of the United States, residing at t e borough of Manhattan, in the city, county, and ,State of New York, have invented a new and useful Improvement in Ice-Machines, of which the following is a specification.

My invention relates to a means and method for making artificial ice quickly and chea and .in a machine that is smaller, and by a method more quickly carried out than by the machinery and the method emloyed for making artificial ice in cakes of arge size and appreciable wei ht.

The object of my invention sing to produce ice quickly, continuously and in a mass that can, as roduced or formed, be cut up into blocks 0 the desired sizes-within prescribed limits-for immediate consumptlon.

In the machine of my invention I employ a hollow. cylindrical vessel, preferablv ver-' tically disposed and contalmng a refrigerant. The ice is formed on one or both surfaces of this vessel-the inner and outer--as the result of spraying water thereon, preferably by a revolving sprayer. The ice, as formed, is loosened b scoring or crushing, or both, is removed y a suitable scraper, and descends by gravity into a conical hopper in which are revo ving scraper plates that work the fine ice downward in the hopper. This hopper is formed with a sur rounding water jacket to drain off the water from the ice, the water being delivered into a tank. The ice falls into an ice compressor and former, preferably contracted at the delivery end. A piston in this ice compressor-actuated by suitable 'devices keeps constantly and progressively forcing the ice particles to the delivery end of the compressor and former, simultaneously packing the ice into a solid mass of progressing length, in which the ice freezes solid and any free water flows away-by suitable means-into the same tank from which the water is preferably pumped up to be sprayed in the continuous 1ce forming process, all of which is hereinafter more particularly set forth.

In the drawings, Figure 1 represents a vertical central section and elevation of substantially the complete device of my invention. Fig. 2 is a section on a horizontal line at the upper part of Fig. 1, and in the same proportion. Fig. 3 is a vertical section 0 operative devices which are placed on top of the machine, as shown in Fig. 1, and have been drawn separate because the sheet holding Fig. 1 lacked the room. Fig. 4 is a side elevation of the ice com ressor and former on a smaller scale from ig. 1. Fig. 5 1s a cross section of the ice compressor an former, and on the same scale at about the dotted line a: w of Fig. 1. 1 Fig.6 is an inverted plan of the lower edge of the throat, connecting the ice making device of the lee compressor and former. Fig. 7 is a cross section, in larger size, of one form of cfi'hndrlcal ice breaker. Fig. 8 is a plan, at t e upper end, of the cylinder containing the refrigerant, showin the u per end of one of'the scraping devlces, an the devices for supportin and adjusting the same. Fig. 9 1s a vertical section through the parts shown in Fig. 8, and Fig. 10 is an elevation and partial section at the lower end of the cylinder containing the refrigerant and lower end of one of the cylindrical breakers.

Similar letters of reference and numerals, throughout the drawings, indicate similar parts.

The foundation and sup ort of the ice making devices comprises a xed ring a and a second fixed ring a, in a higher plane, the ring a being supported by columns b upon any suitable foundation, and the rings a and a connected together, and the ring a supported by columns b These columns are generally shown in Fig. 2 and may occupy a'staggered relation to one another.

0 represents a cylindrical casing secured to both, rings a and a), and adjacent to the inner edges of said rm The ring -a is provided, as a wheel, wit spokes and a central hub a. The cylindrical vessel, vertically disposed and containin a refrigerant, comprises the spaced cylindrical walls d al These walls are held together by connecting rivets 2, and are held apart by the annuli 3, 4; certain of the connecting rivets 2 also passing through said annuli. These cylindrical walls 11 d are flanged at their upper ends, and the upper ring a is provided wlth arms as spokes with a central neck piece a and ring a, and it is to this ring a that the walls of the cylindrical vessel, containing the refrigerant, are secured by suitable bolts or rivets, said vessel being thus suspended .from the parts of the upper ring. I provide suitable plpes for conveying the refrigerant into this cylindrical vessel and for the exit also of the said material so as to establish a circulation. Therefrigerant is preferably the usual anhydrous-ammonia. At the center of the aforesaid rings and the "c lindri- The lower part is also contracted at 6 and asses through the hub a. The lower ring orms a support and. guide and the upper ring'a guide for the hollow, cylindrical axis e and the parts connected therewith.

Extending out from the member e are water pipes 5 and 6, as arms. The pipe 5 terminates in .a spray nozzle 7 within the cylindrical vessel holding the refrigerant, while the pipe 6 extends out from the lower part of the member 6 and passes to the outside of the cylindrical vessel containing the refrigerant, and the pipe itself rises an terminates in a spray nozzle at 7, From both of said nozzles water is discharged against the inner and outer surfaces of this cylindrical vessel containing the refrigerant, and while Ihave thusshown the construction, I do not limit my invention in this respect.

Referring particularly to Fig.3, a stand ard 8 carries a bearing at its upper end for the shaft 9, which is rotated by any suitable power. On this shaft 9 is a bevel wheel 10 which meshes with a large bevel wheel 11, the hub of which surrounds and is keyed to the tubular end 6 of the hollow cylindrical axis. At the upper end of this tubular part e there is a water supply pipe 12, passing through a packing 13, and by this pipe water is introduced into the member or cylinder e from any source of supply, and therefrom through either or both the pipes 5 and 6 to one or more (spraying nozzles 7. In connection with the hollow cylindrical axis e I employ the rings f g.. The ring 7 is provided with arms 7 secured to or formed in one with the hub e and secured thereto and between the lower ring 7 and-upper ring g,

there are a series of columns or supports 14, and I may prefer to connect the upper end of the pipe 6 at its nozzle 7,t o'..,the ringngn for additional support. v p

h and It represent equivalent forms of cylindrical ice breakers. The form h is horizontally scored or grooved,and fthe form k is vertically scoredfor. grooved,-

either form serving for the performance of an equivalent function in cracking and more or less breaking off the ice forming upon the inner or outer surfaces of the cylindrical vessel containing the refrigerant. As a means-providing for the support of the ice breakers h I have shown lugs 15, madepending from the arm f and the other connected to an arm 9 extending-out from the member e. The respective ends of the breaker h are reduced, and eye-bolts receive these reduced ends, and, in turn, pass through the lug 15 and are held in position tion, whereby the periphery of the breakers h maybe adjusted with reference to the inner surface of the cylindrical vessel containing therefrigerant. For the ice breakers h I have shown lugs 18, one extending, below the ring 7, and the other risin 'from the ring 9. The respective ends '0 these breakers are also reduced and are received in eye-bolts 19, passing through the lugs '18 ing from the hollow cylindrical axis e. The

devices as scrapers for removing the ice from the 1nner surface of the cylmdrical vessel contalning the refngerant, are conby clamping nuts 17 in an adjustable relanected to a support from the ends of these arms and consist of scraper bars 6 coming to a sharpened edge at their advancing ortions and, deflector plates 5 the'edges o the bars 6 scraping ofi the ice and the plates i directin the ice away from the center of the mac inc and below the inner surface from which it is removed. Where scraping devices are also em loyed against the outer surface of the cyllndrical vessel containing. the refrigerant, these scraping devices must be carried at their res ctive ends between the rings f and g, and or this pur ose I have shown specially, in Fig. 8, an illustration of a device suitable for such purposeqand comprising brackets of substantially Ulshape 2' with an integral center screw stem 23, which passes through a lug 22 on the ring 9, and is held inposition by clamping nuts at opposite sides of said lug.

The ends ofthe bracket 2' are slotted and receive screw pins upon which are clamping nuts 24:; therefore, to adjust the position of these outside scrapers, various clamping nuts may be loosened and the devices given a slightly radial movement to bring the scrapmg edge nearer to or farther from the- =outer surface of the member d Fig. 9 shows a cross sectionv of this con-.

struction, which is also preferably employed at the lower end of the outer scrapers with reference to the ring f. Below the ice maklng devices, just described, I place a conical hopper k, the upper'flange edge ofwhich is secured to the under-surface of the fixed I ring a, at the inner edge of the ring,and

preferablyin line with the inner surface of the casing a. This hopper is perforated and provided with a conical jacket 70 and a gauze lining m. Into this conical hopper all the ice made in and by the devices in the higher plane,jand just herein described, falls progressively, together with any water into we.

as surplusage that may not have been turned he water passes through the perforations of the conical hopper and the gauze lining, into the jacket is, and is conveyed away by a vertical pipe 25 into a tank I, the ice passing on down through the I hopper and being constantly agitated by scrapers 28. These scrapers 28 are preferably strips of rubber, with to other lower edges secured to a suitable metal frame, the

ends of-which in turn are secured to horizon-- tal-arms 26 and depending arms 27 The arms 26 are in one wit a hub secured around and at the lower end of the hub a, while the arms 27 are secured to the lower end of the hub e. Said arms and said scrapers rotate together with the hollow cylindrical axis e and parts connected therewith. I also provide a rod 29 secured to the lower end of the hub e, and this rod carries a forked agitator 30,

also rotating with the aforesaid parts at the lower end of the conical hopper and its lace of union with the throat 31. This t roat 31 increases in area from the lower end ofthe hopper to its union with the ice compressor and former. This ice .compressor and former is supported on standards 32. It generally comprises a body rectangular in cross sections, as shown in Fig. 5, in

which the lower part 0 is of substantially U shape in cross section and o is the top or cover, said parts being held together with bolts 33, at suitable intervals.

The body of the ice compressor and former is scored longitudinally so as to produce the longitudinal internal ribs 34. There is, as shown in Figs. 1 and 4 a parallel sided section and a tapering section 0 to the ice compressor and former, the said sections being secured together with the bolts 35. The entire ice compressor and former is interiorly provided with a perforated lining r which backs up against the faces of the ribs 34, the lining extending from one end to the other of the ice compressor and former. As shown in Fig. 1, the left-hand end is provided with a large nut s, and longitudinally the several arts are also securely held to ther by tie ro s 36.

t represents a screw s aft passing through the nut s and 4; represents an electric motor secured upon theice compressor or former;

. o the shaft of the motor and '0 a gear; 37

screw shaft t and meshes with the gear or.

pinion '0 so that the power and rotation of the motor are communicated through its shaft and gear to the large ear w. The screw shaft t is longitudinal y grooved and the fp a hub of thelarge gear w carries a'key or spline secured thereto and moving in a groove of the screw shaft, whereby with'the rotation of the large gear the screw shaft t is also rotated, see Fig. 4.

Within the ice compressor and former is a hollow piston u longitudinally movable within the perforated lining r, and the right-hand end of the screw shaft t is sccured in the left-hand end of the hollow piston between the ball-beari heads 40 and 41, which are held to the piston by the collar 39; consequent] as the screw shaft turns, it reciprocat'es t rou h the nut 41, and moves the piston forwar and backward in the ice compressor. This piston is made.

with a head u connected to the tubular body of the piston by long screws, and this head is perforated so that any water in the ice as compressed may flow through the head and discharge into the scoring of the ice compressor through other holes inside the piston, all the water in the scoring eventually advancing by drain pipes 42 into the common tank I, where the water as it collects is pumped out into the pipe 12, todescend into the cylindrical hollow axis a, to be again sprayed against the surface of the cylindrical vessel containing the refrigerant, in the repeating process of forming ice and removing the same.

In the operation of the ice compressor and former, the ice descends within the same through this throat 31. The stroke of the piston is between the position shown in Fig. 1 and the forward end at the tapering section; consequently, as the ice collects, it is periodically pushed forward bodily and forced up against the ice in the tapering section. The water is squeezed out, the ice so lidifying and the water advancing through the perforated lining r into the scoring and making its way by the drain pipes 42 into the common tank Z. As the ice is forced progressively through the tapering section, it comes into the parallel end of the section back of the weighted cover 0 the ice meantime freezing together into a substantially solid mass. As the ice emerges from the exit or mouth of the ice compressor and former, this weighted cover is lifted and gradually thrown back and remains back during the continuous ice making process. As the solid rectangular mass of ice emerges from the ice compressor, it may be cut up into sizes, as desired, for immediate consumption, and by any suitable cutting means.

have shown in Fig. 10, a scraper 43 as secured to the arm f and coming under the lower edge of the cylindrical vessel containing the refrigerant, for the purpose of scraping off the ice which ma form on the lower edge of said vessel. I ave also shown on the free end of the screw shaft t an upright member or block 44, adapted for employ- 1.
