Specification of Letters Patent.

Patented Feb. 2, 1915.

Application filed May 24, 1913, Serial No. 769,582. Renewed June 9, 1914. Serial No. 844,082.

T all whom it may concern.

Be it known that I, TIMOTHY FRANKLIN Prmno, a citizen of the United States, and a resident of Tuckerton, in the county of Ocean and State of New Jersey, have invented a new and Improved Ice-Making Apparatus, of which the following is a full, clear, and exact description.

This invention relates to ice making machinery and has particular reference to apparatus employed in connection with the manufacture of ice by freezing the same in cans plunged into a tank of brine, the type of devices to which this invention relates being set forth in my previous Patent, No. 1,055,980, issued to me on the 11th of March, 1913.

Among the special. objects of this invention is to provide an apparatus involving the use of a pump or an analogous means in connection with each can of water for the purpose of agitating the water in the can during the process of freezing so as to prevent the incarceration of air bubbles which cause the ice to have a snowy appearance and hence render the ice less salable. I have discovered and have proved in practice that the cloudy or snowy appearance of the ice due to the inclosed air bubbles may be obviated by keeping the surface of the water in the can open and causing the water to be circulated more or less while the freezing is taking place at the bottom of the can upwardly toward the top.

A further object of the invention is to so arrange the several agitating pumps with respect to the brine tank as to simplify the manipulation of the pump connections and nor .zles with reference to the introduction and withdrawal of the cans into and from said tank without the necessity of making any disconnections of the devices.

A still further object of the invention is to simplify and improve the various details of mechanical devices.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a plan view showing the re-. lation of the pump mechanism to the ice cans and framework at the top of the brine tank; Fig. 2 is a side elevation of the same,

parts being in section; Fig. 3 is a plan view of a larger portion of the brine tank and in dicatmg the relation thereto of the agitatmg mechanism; Fig. 4 is a plan view of a section of a pump rod, a clamp secured thereto, and a pair of pistons connected to sa d clamp; Fig. 5 is a vertical sectional cletail on the line 55 of Fig. 3, indicating the means for varying the stroke of the pump pistons; Fig. 6 is a view angles to Fig. 5 from the plane indicated by the line 66 of Fig. 3; Fig. 7 is a detail of the pump piston packing; Fig. 8 is a detail of the agitator nozzle; Fig. 9 is a plan View of the upper end of the nozzle connection described below, and Fig. 10 is a detail of the connection between a driving eccentric and a pump rod. 1

The several parts of the device may be made of any suitable materials and the relative sizes and proportions as well as the general layout of the device may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed.

I show at 10 a brine tank having any suitable number or size of compartments 11 formed therein by means of the rectangular framework 12, each of said compartments being designed to accommodate a well known form of freezing can 13. The cans 13 are intended to be inserted into the brine through the rectangular spaces of the framework and there held in place during the freezing operation according to the well known process.

Extending longitudinally of the brine tank framework 12 are rails 14. Each of these rails extends along the longitudinal rib separating one longitudinal row of compartments 11 from the next. In other words, the number of rails 14 is preferably just one half of the number of longitudinal rows of compartments. These rails 14 are fixed in position with respect to the frame 12 in any suitable manner and are strong and rigid enough to withstand not only the trafiic above the brine tank due to the manipulation of the cans of water and ice, but also are intended to carry on their under surface the pump portions of the agitator mechanism. As shown in Figs. 1, 2 and 3, that portion of the rail 14L between each two adjacent compartments 11 is fitted with a pair of pump cylinders 15 extending longitudinally of the rail in alineat right" inders are secured permanently and rigidly in position by means of clamps 16 and- 17 secured to the under surface of said rail. Each cylinder is provided with a piston'lS connected to and operated by a piston rod 19. The piston rods 19 of each pair of pumps terminate adjacent each other and are connected detachably to a clamp 20 in the space, above referred to, between the cylinders. Said clamp is shown provided with a pair of spaced jaws 21, each having an open side. Each piston rod is fitted at its end with a fixed head '22 which may be in the form of a nut upset or riveted in place and adapted to lie upon the inner face of one of said jaws 21, the rod being adapted to slip in or out of said open side of the jaw. WVhen the piston rod is put in place as just by means of

nuts

23 and 24. The piston is so made as to include a flexible bucket 25 adapted to be connected to the end of the pistonirod 19' and provided on its inner surface with an annular seat or groove 26 into which is adapted to be sprung a split ring 27 which serves to keep the outer edge of. the bucket spread"outwardlyinto close fitting engagement with the inner surface of the cylinder.

'Located at any convenient place in proximity to the brine tank is a power shaft128 supported in bearings 29 substantially par allel to one side of the tank. This shaft is adapted to be driven by a power belt or chain indicated at 30. This shaft has mounted thereon any suitable number of adjustable eccentrics 31, such number preferably coinciding with the number of rails 14 above described. Each eccentric 31 is provided with a strap 32 to which is connected apump rod 33' which extends alongpreferablybeneath the porresponding rail 14, and the pump clamps 20 are securedrigidly to said rod by means of clamps 3 1. The several eccentrics connected to the power shaft 28 are preferably staggered [so that me power required for operating all of the pumps at the same time will be distributed or equalized as much as possible throughout the system. In order to accommodate the apparatus to tanks orsystems of varying sizes and also to vary the operation of some of the pumps without disturbing others and for other reasons, I provide ,means for readily varying the throw of the eccentrics,

and hence the stroke of the pumps without stopping the engine or interfering with the ordinary-or regular speed of the power shaft. As a simple and effective means for accomplishing this result, I connect each eccentric 31 to the power shaft 28 through a block 35 lreyed tojthe shaft and'havingslidas shown in Fig. 5.

described, it will be set and locked able connection with the eccentric disk 31, In other words, the center of the disk or eccentric is adjustable radially toward or from the axis of the shaft and block 35. To this end I provide a screw having threaded engagement in a stationary nut 37 in the end of the slot 31 opposite the block 35. Said screw 36 has connected to it at its inner end a miter gear 38 extending laterally from said block, as shown in Fig. 6, and meshing with a pair of similar gears 39. Each of said gears 39 is sleeved upon the power shaft and has connected to it a hand wheel 4:0 concentric with said shaft. In normal operation said hand wheel and eccentric, and the devices connected between the same, all rotate with the shaft, and the stroke of the pumps corresponds to the eccentricity or throw of the eccentric in any adjustment. In order, therefore, to vary the eccentricity of the eccentric at any station, it is but necessary for the operator to grasp one of the hand wheels 40, and either hold it from rotation while the power shaft is operating, or otherwise manipulate it for the purpose of operatin the screw 36 to cause the radial shifting o the eccentric while the shaft is running. The pump rods 33 are preferably guided and supported in bearings 33 formed in the cross pieces of the frame 12.

Connected to the outer end of each pump cylinder is atubular arm 41, the connection being through a hinge joint 4C2 providing for the swinging of the arm in a horizontal plane beneath the pump and rail thereover; To the opposite end of the arm -11 is connected a nozzle arm 43 having a telescopic section 44 fitted thereon. Said nozzle arm 43 is connected also by a hinge joint 1 .5, as shown in Figs. 1 and 2, adapting it to swing in vertical planes whereby it may not only be adjusted vertically with respect to the depth of the water in the can being treated, but it may be swung upwardly to clear the upper edge of the can and then swung in the horizontal plane with the arm ll out of the vertical range of the can, enabling the can to'be inserted or withdrawn without any danger of interference with the pump arm connections. As one convenient and satisfactory means for connecting the telescopic nozzle 44 to the other portion of the nozzle arm I provide the upper end of said nozzle with a pair of spring fingers 46 formed integral with said nozzle by meanseerie formed adjacent the lower end of the stationary member of the arm 43, formed by a circumferential groove 50. By beveling the free ends of the fingers, as shown at 46, the nozzle may be easily slipped upon the other member, and after being applied thereon, may be slipped along to any desired distance, but the form and arrange ment of the fingers 46 will prevent the accidental removal of the nozzle from the other member by engagement with said shoulder 49. The lower end of the member 48 is preferably flared or spread slightly, as indicated at 43, for the purpose of making a substantially close fit with the inner surface of the nozzle 44 whereby special packing is avoided. The lower end of the nozzle is provided with an elbow 51 for the purpose of directing the currents of water as may be required.

The operation of the device may be briefly described as follows: l/Vith the power shaft in rotation in either direction and the several pump rods 33 being reciprocated thereby through the eccentrics 3l, the pump pistons will all be reciprocated according to the eccentricity or throw of the eccentrics as above described. A can of water may be introduced into any vacant compartment 11 after the arm 41 and its nozzle connection 43 have been swung in a horizontal plane beneath the rail 14. After the can has been set in the brine and secured in any well known manner, said arm 43 is swung outwardly to or toward the position indicated in Fig. 1, and the nozzle arm 43 swung downwardly into or in the position shown in Fig. 2 with the nozzle 44 extended so as to reach beneath the surface of the water which, in practice, must be far enough below the upper edge of the can to provide for the necessary expansion during the freezing. By operating the pumps at a comparatively slow speed, the water at the center of the top of the can will be kept open, preventing the freezing over at this point while the ice is forming at the sides and bottom thereof. Any sediment which may be in the water will collect in the pocket or cap resulting adjacent the top when the freezing is nearly completed, and such dirty water, if desired, may be removed therefrom by any suitable or convenient means (not shown) and the cavity, upon being filled with clear water,

will insure a perfectly clean clear block of ice when finished.
