PUMP.
Application filed December 20, 1926. Serial No. 155,932.
The main objects of this invention are:
First, to provide an improved high pres sure pump assembled as a unit whlch 1s very compact and one in. which the most of the moving parts are housed or inclosed and eflectively protected and lubricated.
Second, to provide an improved pump which is Well adapted for use in creamerles and the like where freedom from dirt and grease is highly desirable.
Third, to provide an improved pressure pump embodying these advantages which is comparatively economical and at the same time durable.
Objects pertaining to details and economies of construction and operation of my 1nvention will definitely appear from the detailed description to follow. The invention is clearly defined and pointed out in the claims.
A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:
Fig. 1 is a side elevation of a structure embodying the features of my invention as especially designed by me in an apparatus for treating milk known as a viscolizer.
Fig. 2 is a fragmentary view partially in vertical longitudinal section on a line corresponding to line 2-2 of Fig. 3.
Fig. 3 is a fragmentary view partially in horizontal section on a line corresponding to line 33 of Figs. 2 and 4.
Fig. 4 is a fragmentary perspective view showing the arrangement of the auxiliary housing for the driving connections.
Fig. 5 is a perspective view of the eccentrics and of the driven gear connected thereto.
Fig. 6 is a fragmentary perspective view with the cap or top portion of the housing removed, further illustrating the relation of the parts.
Referring to the drawings, in the embodiment illustrated, I provide a base 1 having a chamber or housing 2 therein for certain of the mechanisms as will be hereinafter described, this housing having a removable top or cap 3.
The structure illustrated is especially designed by me for a milk treating apparatus, known commercially as a viscolizer, this unit being designated generally by the numeral 4. As the details of this unit form no part of my present invention, I do not fully illustrate nor describe the same herein.
This unit includes pumps having plunger rods 5 which are arranged through stuffing boxes 6 carried by a closure plate 7 for the opening 8 at the end of the housing. The mounting of the stuffing box upon the plate 7 instead of Within the wall housing is a matter of manufacturing convenience and also facilitates the assembling and disassembling of the parts.
The housing 2 is adapted as a lubricant receptacle, it having a curved bottom 2 (see Fig. 2), the purpose of which will appear as the description proceeds.
The end walls of the housing are provided with bearing-like bosses 9 and 10 in which the non-rotating shaft 11 is supported, the shaft being held against rotation by the set screw 12. These bosses are open at their ends to permit the introduction and removal of the shaft, the openings being closed by the plates 13.
The end walls of the housing are also provided with bearings not detailed for the driving shaft 14, the outer endof one of the bearings being closed by the plate 15, the shaft projecting through the other bearing to receive the sprocket wheel 16. This sprocket wheel is connected to the motor indicated generally by the numeral 17 mounted on the bracket 18 on the housing. An auxiliary housing 19 is provided for the driving connections of the motor to the shaft 14.
.On the shaft 11, I mount a plurality of eccentrics 20, these eccentrics being, in the embodiment illustrated, formed integrally and lying side by side without space between them and being suitably indexed relative to each other.
The gear 21 is, in the embodiment illustrated, also formed integrally with the eccentrics. The several connected eccentrics, in effect, constitute an eccentric shaft, and for brevity, I have herein designated the same by the broad term cam shaft. The gear 21 meshes with a pinion 22 on the shaft 14 so' that the gear 21 and eccentrics are driven as a unit or single cam shaft.
The pitmen or eccentric rods 23 are provided with suitable straps 30 embracing the eccentrics, these straps lying side b side and in sliding bearing engagement. ne of the outer straps is supported by a shoulder 31 at the inner side of the gear 21 and the other by a flange-like collar 32, the collar being also formed integrally with the eccentries.
The pitmen or eccentric rods 23 are connected to the slides or cross heads 25 by the pins 24. These cross heads are arranged side by side in coacting sliding contact upon the slideway 26, constituting a portion of the bottom of the housing, this part being suitably elevated above the lubricant well portion 2 of the housing bottom. The slide 26 has a flat face which is, asv illustrated, common to all of the cross heads.
Parallel slideway end members 27 project upwardly from the slideway and constitute side members or supports for the outer cross heads. The slideway top member 28 has a flat inner face common to all of the cross heads and is bolted upon the end members 27. This top has an upwardly projecting wall 33 at its rear edge and ends, a portion of its forward edge, at 34, lying close to the periphery of the gear 21 so that a considerable portion of the lubricant picked up by the gear is discharged upon the slideway top member, the gear acting as a pump providing a constant supply of lubricant when the machine is running.
To. make this gearv efficient as a pump, the housing is suitably conformed to the gear, as shown in Fig. 2, that is, the periphery of the gear throughout its greater portion is quite close to the wall or housing.
The bottom of the slideway projects slightly beyond the forward edge of the slideway top so that the lubricant discharged upon the slideway will flow off the front edge of. the top upon the bottom.
To further distribute the lubricant to the cross heads, the top is provided with an opening 29 above the path of each cross head. The result is that a large amount of lubricant is continuously supplied to the cross head. The eccentrics are also kept thoroughly lubricated, the eccentrics dipping into the lubricant on the down-stroke, the lubricant being carried up and delivered between the coacting faces of the eccentric straps, and also the lubricant flows down the connecting rods 23 when the same are forwardly inclined to carry lubricant to the pins 24, and when rearwardly inclined, as on the down-stroke of the eccentrics, the lubricant is directed to the eccentrics. Thus all ofthe parts are very efficiently lubricated, the structure is very compact and the number of parts is minimized.
Further, the moving parts are so encased that the escape of lubricant is effectively prevented, thus well adapting my improvements for such uses as in the viscolizer which is used, as stated, in the treatment of milk where cleanliness is greatly to be desired. H
A further advantage is that the parts are economical to produce and very easily assembled, and the structure is well adapted for high pressure pumps.
