CHURN.l

SPECIFICATION forming part of Letters Patent No. 710,436, dated October '7, 1902. Application filed .Tune 26. 1902. vSerial No. 113,346. (No model.)

To (LZZ whom, it may concern,.-

l'e it known that I, ELIAS E. DAIL, a citizen of the United States, residing at Ayden, in the county of Pitt and State of North Oarolina, have invented a new and useful Churn, of which the following is a specication.

My invention'is an improved churn; and it consists in the peculiar construction and combination of devices hereinafter fully set fori-h and claimed.

In' the accompanying drawings1 Figure lis a vertical longitudinal sectional view of a churn embodying my improvements, the flasher-shaft being shown in an elevated position. Fig. 2 is a similar view of the same, the dasher-shaft being shown lowered and in its operative position in the churn vessel. Fig. 3 is a top plan view of the same.

In the embodiment of my invention I provide a longitudinall \7 -movable revoluble lflasher-shaft l. The same is hereshown disposed in a vert-ical position and engages the outer sides of a pair of horizontally-disposed bearings 2, which connect the longitudinal bars 3 of a supporting-frame that are respectively disposed above and below the said bars 3. IThe said bearings are shown as secured to the bars 3 by bolts 4L and as having adjusting-slots 5, in which the said bolts operate, so that the said bearings may be adjusted longitudinally on theY bars 3. The latter are shown as having their ends connected by cross-bars 6. A base 7, which forms the support for the churn vessel 8,is secured between the lower portions ot' legs 9, which support the frame composed of the bars 3 6.

I do not desire to limit ,myself to the construction of the frame herein before described as the same maybe modified without departing vfrom the spirit of my invention.

A crank-shaft 10 is shown as horizontally disposed and supported transversely on the bars 3 by bearings 1l. On the said craukshaft is a pulley l2, which is here shown as disposedbetween the bars 3. An endless` belt 13 passes around the outer sides of'the pulley l2 and shaft 1, and the leads ofthe said belt are oblique to the said dasher-shat't, as shown in Figs. l and 2. The recesses Min the bearings 2, engaged by the dasher-shaft, are in the outer sides of the said bearings andthe said recesses are semicircular in form.

The belt 13` keeps vthe dasher-shaft in engagement with the said bearings and recesses. By shifting the bearings the 'belt maybe maintained at the requisite tension. By moving the bearings 2 toward the pulley l2 the belt 18 may be so slackened as 1o enable the flasher-shaft to be readily removed from the bearings. A direction-roller 15 is journaled in bearings lo on the bars and bears on the upper lead of the said belt.

It will be understood that by turning the pulley l2 by means of its crank-shaft power is com m unicaied to the dasher-shaft through the belt 13 and the dasher-shaft is rotated in the bearings 2. in the direction'indicated inthe arrow in Fig. 2, the oblique dispositionof the leads of the belt with reference to thedasher-shaft and the movement Vof the belt cause the dasher-shaft to move downwardly until it reaches the bottom o't' the churn vessel 8, after which it continues to revolve in a lowered position in the churn vessel long as the pulley l2 is rotated in the sainedirection. When the butter has been churned or formed by the action ot' the revoluble dasher-shaft, the operator turns the pulley l2 in the reverse direction, as indicated bythe arrow in Fig. l, thus causing the belt, owing to the oblique disposition of its leads with reference to the dasher-shaft, to reverse the rotation of the dasher-shaft and move the same upwardly out of the churn vessel. I-Ience by my peculiar construction and arrangement of devices the pulley and beltwhich rotate the dasher-shaft also move the latter longitudinally in either direction,

as may be required to place it in the churn vessel or remove it therefrom. 'lhe bottom of the churn vessel forms a stop to limit the downward movement ofthe (flasher-shaft, and while the same is being revolved in the direction which causes it to move downwardly the said dasher-shaft presses downwardly on the bottomof the churn vessel and holds the same appropriately on the base. Thus the downward axial thrust of the dasher-shaft is utilized to keep the churn vessel from being displaced by the jar incident to the operation of the machine. Moreover, by alternately reversing the direction of movementof the driving-wheel the dasher may be given a combined axial or longitudinal and rotary move- Then the pulley l2 is turned ment in opposite directions, which will assist in causing a thorough agitation of the contents of the churn vessel and will expedite the gathering of the butter. Furthermore, it Will be understood that While the illustrated embodiment of myinventionis preferable as a means for carrying out my invention, be

cause of the simplicity thereof, I do not desire to be limited thereto, as equivalent means may be employed for accomplishing the described operation of the dasher in Which it performs the dual function indicated.

Having thus described my invention, .I claim` l. In a churn, the combination of a longitudinallymovable, revoluble flasher-shaft, bearings therefor, a pulley having its axis at right anglesto the dasher-shaft, and a belt connecting the pulley and dasher-shaft, having its leads oblique to the latter and thereby adapted to rotate and also move said shaft longitudinally, substantially as described.

2. In a churn, the combination of a longitudinally-movable revoluble dasher-shaft,

adjustable bearings therefor open on one side, to adapt the shaft to be removed therefrom, a pulley having its axis at right angles to the dasher-shaft and a belt connecting the pulley and dasher-shaft and having its leads oblique to the latter, substantially as described.

3./ In a churn, the combination of a revoluble vertically-disposed dasher-shaft movable longitudinally in its bearings, a pulley having its axis at right angles to the dashershaft, a belt connecting the pulley and flashershaft having its leads oblique to the latter and thereby adapted to rotate and also move the shaft longitudinally in a Vertical direction, and a churn vessel, the latter and the dasher-shaft having coacting stops.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

ELIAS E. DAII.
