Specification of Letters Patent.

lllatented Mar., 29, 1921i.

Application led July 15, 1920. Serial No. 396,515.

To all fw iwf/n it may concer-n.'

ille it known that I, THOMAS DoLrNAn, a citizen of .lugo-Slavia, residing at Piney Forl, in the county of Jefferson and State of Ohio? have invented certain new and useful improvements in Churns, of which the following is a specification.

rThis invention relates to certain new and useful improvements in churns.

T he primary object of the invention isto provide a manually operable churn embodying a receptacle section and a dasher sec* tion with the latter supported upon a vertically adjustable frame whereby the dasher may be removed from the receptacle by the elevation of the frame.

A further object of the invention residesV in the provision of a vertically adjustable frame for supporting a dasher operatively7 positioned within a churn receptacle, rack and'pinions being associated with each side of the frame for simultaneous operation to elevate the iframe and dasher supported thereby.

lilith the above and other objects in view, the present invention consists in the novel form, combination and arrangement of parts hereinafter more fully described in connection with the accompanying drawings, and in which like reference characters indicate similar parts throughout the several views.

In the drawings,

Figure 1 is a front elevational view of a churn constructed in accordance with the present invention showing the dasher supported on the vertically adjustable frame with the rack and pinion devices for raisingand lowering the frame,

2 is a side elevational view, partly broken away,

Fig. 3 is a horizontal sectional view talren on line llllll of Fig. 1 showing the pin wheel meshing with the lantern gear,

Fig. Al is a cross sectional view talren on line lV-V of 1. showing the radial arms of the dasher within the churn receptacle,

Fig. is a cross sectional view taken on line V-V of Fig. 1, showing` the supporting feet for the churn receptaclea Fig. 6 is a vertical sectional view taken on line VL-Vl of Fig. 17 :showing the lantern gear keyed to the dasher shaft and 7 isa perspective view of one of the cover sections removed from the churn receptacle.

Referring more in detail to the accompanying drawings, there is illustrated a manually operable churn embodying cylindrical receptacle 1 supported at its lower end upon angle feet 2 and 3 and secured thereto by suitable fastening devices. rll`he open upper end of the receptacle 1 is closed by a cover formed of semi-circular sections lhaving registering axial openings 5 cut upon the chordal line thereof to accommodate the passage of the dasher shaft while adjacently positioned handles 6 are carried by the cover sections d to project laterally of the receptacle 1 as shown in Figs. 2 and 7 to facilitate the removal of the cover sections.

The dasher and shaft are supported on a frame that is adjustably mounted upon the receptacle 1, the frame being of inverted U-shaped form embodying side legs 7 and 8 and upper transverse connecting bars 9. Two pairs of guide straps 10 are dian1etrically secured to the upper end of the receptacle 1 in vertical alinement with the supporting feet 3, while spaced bars 11 extend between each pair of straps as shown in Fig. 1. The lower ends of the frame bars 7 and 8 freely extend through the strap guides 1() as shown in Figs. 2 and 3 and are provided upon one face thereof with rack teeth 12 for purposes presently to appear.

To effect a vertical adjustment of the dasher supported frame, a shaft 13 is jour naled beneath the receptacle 1 in the angle feet 3 with a dasher gear 14 upon each end thereof. A vertical shaft 15 is journaled at each side of the receptacle 1 in the horizontal portion of the angle feet 3. rlhese shafts carry bevel gears 16 at their lower ends in constant mesh with the bevel gears 14 while the upper ends of the shafts 15 are g'ournaled in brackets 17 carried by the strap connecting bars i1 and are provided with bevel gears 18 upon the upper ends thereof. A stub shaft 19 is horizontally journaled in each pair of strap bars 11 and is provided with a pinion 20 in mesh with the rack teeth l?. of the bars 7 and 8 while bevel gears 21 upon the shafts 19 mesh with the bevel gears 18 upon the shafts 15. rlhe shaft 19 adjacent the frame bar 8 is provided with a wrench end 19 for rotating all of said gears and pinions in a manner to be later described.

The dasher and mounting therefor are more clearly shown in Figs. 1, 3, 4, and 6,

the dasher comprising a shaft 22 carrying agitating blades 23 upon the lower ends thereof while the upper end of the shaft is journaled within the arms 24 projecting inwardly from the frame arm T and overlying the receptacle l. A nut 25 is secured to the upper end of the shaft 22 to retain the shaft rotatably mounted within the arms 24;. As shown in Fig. 6, that portion of the shaft 22 extending between the arms 24C is rectangular in cross section and extends through the rectangular bore of the lantern gear 26 confined between the arms 24. Apower shaft 27 is journaled in the arms 'T and S at a point above the arms 24 and carries a pin wheel 28 in mesh with the lantern gear 26 and rotated by the crank handle 29 upon the shaft 27.

In order to raise or lower the dasher 22 in the receptacle l, a wrench is applied to the end 19 of the stub shaft 19 and rotation of the shaft 19 adjacent the armS is directly communicated by the pinion 2() to the rack teeth l2. The meshing gears 18-2l and 14-16 communicate motion to the stub shaft 19 adjacent the arm 7 so that the side legs or arms 7 and 8 of the frame are simultaneously raised and lowered. The shaft 27 carrying the pin wheel 28 being rotated by the crank 29, communicates motion to the dasher shaft 22 by meshing with the lantern gear 26. The cover being formed of separable sections, access to the receptacle may be readily obtained While the relative depth of the dasher within the receptacle is also under the control of the operator.

While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed as new is:

A vertically adjustable mechanism supporting member comprising in combination with a base support, a pair of horizontal stub shafts journaled at opposite sides of the support, a pinion fixed on each shaft, a gear on the outer end of each shaft, a pair of vertical shafts journaled at opposite sides of the support, a gear on the upper end of each vertical shaft in mesh with the gear on the end of the adjacent stub shaft, a hor1- zontal shaft journaled in the base support,

.meshing gears on the adjacent ends of the horizontal shaft and the lower ends of the vertical shafts, an inverted U-shaped mechanism supporting member adjustable on the support, rack bars carried by the supporting member engaged by said pinions, and a manually operable mechanism carried by the supporting member, one of the stub shafts being constructed to receive a crank arm for rotating all of the shafts to effect raising andlowering of the mechanism supporting member.

In testimony whereof l afIiX m signature.
