Description
Patented June 23, 1936 UNITED STATES PATENT OFFICE 1 Claim.
The invention relates to churns, and particularly to the churn dasher mechanism as used in churns, and has for its principal object the provision of an improved construction of driving mechanism for the dasher, and also to an improved construction of a churn dasher.
A further object of the invention is the provision of a churn dasher, consisting of a sleeve member adapted to be secured to the dasher shaft, and having blades extending radially thereof, said blades being curved and inclined, the curvature of the blades being substantially that of degrees, or a quadrant, the forward edge of the blade being nearer to one end of the shaft than the following edge of the blade, so that the material operated on will be given a swirling motion as the dasher is actuated.
The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawing, in which Figure l is a side view in elevation of a churn pump showing the improved churn dasher mechanism mounted thereon,
Figure 2 is a fragmentary top plan view,
Figure 3 is a sectional view on plane indicated by line 3 3 of Figure 2,
Figure 4 is a transverse sectional view of the churn shaft and showing the dasher, on a plane indicated by line 4-4 of Figure 1, and
Figure 5 is a transverse sectional view of one of the dasher blades taken on the plane indicated by line 5-5 of Figure l.
Referring to the drawing, in which similar reference characters are used to designate corresponding parts in all the views, a churn dasher top or lid is shown at I0, and has mounted thereon a pedestal Il, provided with a bearing I2 in which is journaled a drive shaft I3, said drive shaft being adapted to be driven by any suitable power, a belt pulley I4 being shown as a selective means of driving the shaft I3, and obviously may be connected up with any suitable motor or other means of propulsion. Secured to the shaft I3 is a beveled gear I5.
Mounted also on the lid or cover I0 is a vertical tubular bearing I6, in which is journaled a driven shaft I'I, having keyed or otherwise secured thereto at its upper end a beveled gear I8 that is enmeshed with the beveled gear I 5. The lower end of the driven shaft I1 has an integral socket member I9 thereon to receive one end of a dasher shaft 20, 2| designating a set kscrew threaded into an opening in the wall of the socket I9 and adapted to engage one or the other of a series of recesses 22 in the shaft 20.
The parts II and I6 may be formed integral with the cover or lid I0, or may, as shown in the drawing, be mounted on a plate 23 secured to the cover or lid II) by means of screws or other driven fastenings 24. Lubricating ducts 25 are also shown for the shaft I3, and a lubricating duct 26 for the shaft I'I and it is apparent that any means for applying lubricant to said ducts may be provided.
The churn dasher consists of a sleeve member 2l secured to the shaft 20 by means of a set screw 28, or any analogous method, and said sleeve may obviously be adjusted on said shaft to any position that is desired for the most successful operation of the dasher and of the churn. The dasher is provided with two blades that-extend radially from the sleeve 21, from opposite sides thereof, and the blades are preferably integral with the sleeve 21. The blades are concaved, as shown, the blade being indicated at 29, and the concavity at 30, the blades being inclined, as shown best in Figure 5, and the arc described by the blade in the cross section being substantially 90 degrees or a quadrant. The leading edge of the blade 3l will therefore be nearer to the selected end ofthe shaft 2G than the following edge 32, and the concavity in the blade will have the effect to drive the milk or other material through which the blade is actuated downwardly and cause the material to swirl, and thereby thoroughly agitate it so as to quickly separate the butter fat therefrom in the operation of churning.
As shown in the drawing the dasher structure is mounted on the shaft so that the swirling action will be downwardly, as above stated, and obviously by reversing the dasher so that the leading edge is closer to the lower end of the shaft than the following edge, the opposite effect will be the result, and furthermore, it will be obvious that two or more dashers may be mounted on the same shaft and arranged in different positions so as to more thoroughly agitate the milk or other material.
I claim as my invention: In a churn dasher, a base plate, a pedestal on the base plate having spaced apart upwardly ex- Vbearing. member, gearing between said shafts,
and a socket member on the second mentioned shaft to hold a dasher, said socket member being inset into said base and intimately engaged and braced by the latter and extending a distance below the base whereby it will pass through a top v or lid of a churn, said pedestal bearing arms and bearing member being integral with the base plate, and that portion of the first mentioned shaft between the spaced partsA of the pedestal constituting a handle.
