IVIOIOR-DRIVEN PASTEUEIZER.

Application "filed Gctobei 2, 1922. Serial No. 591,710.

T 0 all whom it may concern:

Be it known that 1, Mounts Gonnnnnonn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in lvilotor-Driven Pasteurizers; and I do hereby declare that the following is a full, clear and exact description thereof, reference being had to the ac coinpanying drawings. and. to the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in apparatus for treating milk for pasteurizing the same under the well known batch process of pasteurizing, or for otherwise conditioning milk and other liquids.

lhe invention is herein shown as adapted to the type of apparatus. disclosed in my United States Letters Patent. Number 1,438,594, dated December 12th. 1922. and relates in part to means for quickly converting a motor driven pasteurizing apparatus to an overhead shaft and belt-driven apparatus. and in part to special means in a motor drivenapparatus for supporting. from the vessel or receptacle. the motor and the speed reducing transmission mechanism be tween the motor and agitator.

Other objects of the invention are to produce a structure of this character which simplifies the installation of a pasteurizing apparatus in the space in a dairy reserved therefor. to means for minimizing the transmission of vibration of the driving motor to the receptacle or vessel and to means for adapting the transmission to drive other apparatus used in association with pasteurizing apparatus.

The invention consists in elements. and combination of elements. shown in the drawings and described in the specification, and is pointed out in the appended claims.

As shown in the drawings:

Figure 1 is a side elevation of a pasteurizing apparatus embodying my invention.

Figure 2 is a vertical section on line 2-2 of Figure 3.

Figure 3 is a partial section and partial elevation, the section being indicated. on the line33 in Figure 2. j

As shown in the drawings, 10 designates the pasteurizing receptacle supported on suitable legs 11 and provided centrally with an outlet 12 which, as shown, is connected by a pipe lt with a pump 15 by which the contents of thereceptacle are lifted to a place of disposal of the liquid.

16 designates the upper end of the shaft of the agitator, shown in my aforesaid application, said agitator shaft beingrotatably mounted in avertical bearing 17 that is fixed to a beam 18 which extends diametrically across the top side of the pasteurizing receptacle and may be attached to the wall of the receptacle in the manner shown in my aforesaid application. 19 designates a pulley fixed to the shaft 16. About this pulley is trained a driving belt 20. which belt is also trained about a driving pulley which is fixed to a short upright shaft 22 that is rotatably mounted in an upright bearing sleeve 23, which is made integral with the upper wall of a gear box 2st that is supported at or about the level of the beam 18 of the receptacle 10.

As shown in my prior application. the transmission gear enclosed in the gear box is adapted for driving connection from a shaft. In the present construction. the said shaft 22 is also adapted for driving connec- -tion from a motor 25, preferably an electric motor, which is supported at one side of the receptacle and below the top thereof. .The means for supporting said motor on the receptacle and for connecting its armature shaft.- to the upright shaft 22 of the driving transmission are made as follows:

26 designates a bracket comprising a hori zontal member s7 that lies upon and is bolted or otherwise fixed to the beam 18, a vertical member 28 and connecting web 29, shaped to give general triangular formation to the sai bracket. 30 designates an up right plate which lies with its side face at its upper end face against the outer face of the bracket member 28 and is attached thereto by the same bolts 31 which fix the gear box 24L rigidly in place in a manner to be supported'on the beam 18. its shown 'said bolts extend loosely through openings in the upright member 28 of the bracket and the plate 30, and are threaded intoregister 'ing openings in the adjacent si e wall 32 ofthe gear box. The motor 25 is fixed to said plate 30 in the manner of a wall mounting. the frame of the motor being pro' vided with a bracket through which fastening bolts 84e'extend to hold it in place. Bolted to, orotherwise attached to said a horizontal shaft 36. Fixed to one end of said shaft 36 is a pulley 37 that is connected by a belt 88 to a pulley 39 on the arma ture shaft of the motor 25. Fixed to the other end of the shaft 36 is a smaller pulley 40 that is connected by a belt e1 with a larger pulley d2. The latter pulleyis pinned upon or otherwise secured to a horizontal shaft 43 which is rotatably mounted in suit-,

able bearings hi, il supported by the side walls of the gear box. Fixed to said. shaft 43, within the gear box, is a beveled pinion 45 which meshes with a beveled gear 46 fixed to the lower end of the shaft 22.

With this construction, it will be noted that the ratios of the motor pulley 39 to the transmission pulleys 3?, l0, 21 and 19, and the ratios of the gears 45, 4c are such as to suitably reducethe high speed of an ordinary commercial motor to a relatively slow speed delivered to the agitator shaft through the belt 520 it being understood that the agitator shaft will be operated at a slow speed during the pasteurizing operation. V

' One of the features of the presentinven tion resides in mounting the motor 25 well up towards the level of the beam 18'which carries the agitator shaft and the motor supporting plate 80, as well as the gear box and the transmission associated therewith, and in locating a portion of the speed reducing transmission towards" the lower end of said plate 30. This arrangement has the effect, so to speak, of decreasing the lever arm of the motor with respect to the mechanism which'it drives, and also provides a very convenient and compact means of arranging the speed reducing mechanism between the motor and the driving agitator shaft 19. Therefore, transmissionof vibra tion to the receptacle, due to the high speed of the motor, is greatly minimized.

It is desirable, because of sanitary rules and regulations, that a space shall intervene 7 between the motor mounting plate 30 and the side wall of the pasteurizing receptacle. For this purpose the bracket 26 can be extended slightly beyond the plane of the verti cal side of the receptacle, as shown in Figure'2, to space the upper end of the motor mountin late from the rece )tacle wall h I 7 and the lower end of said plate may be spaced from said wall by a set screw 47 threaded through said plate and bearing at its end against. the outer face of saidreceptacle wall.

It will be observed that by interposing' the motor mounting plate between the upright flange or member 28 of the bracket 26 andth'e adjacent side wall of the gear box, said: plate can be very rigidly connected to the load carrying element of the apparatus,

to-witz the beam 18, and it will be furthermore observed that said construction prorides a very compact and rigid means of joining the. gear box tosaid and to thefangle bracket of saidbegi'rn, i

The construction described enables the pasteur z ng;apparatus to be installed at the most CODVcIHBHt place in a dairy and without reference to overhead driving shafts.

At the same time the construction is such that, with the use of shorter screw bolts 31 the gear box can be-attached directly to the upstanding memberof the angular bracket 26 so as to arrange the transmission gear for connection to a driving shaft when so de sired, in which event the motor and its mounting plate are omitted and driving power can be transmitted by belt to the shaft 43. j Preferably the said motor and a portion of the transmission mechanism is enclosed by a hood 4-8 which can be removably at tached to the motor mounting plate in any suitable manner. 7

By extending the shaft l-B-laterally from the gear box 24, it may be made to receive a pulley 49 by which to-drive, through a suitable belt 50, the pump 15 or other auxiliary device useful about the pasteurizing device, such as a milkforce pump, a: brine pump, etc. I
