Specification of Letters Patent.

Application filed August 12, 1914. Serial No. 856,408.

To all whom it may concern:

Be it known that 1, WILLIAM L. LOGAN, a citizen of the United States, residing at Clarendon, in the county of Donley and State of Texas, have invented a new and useful Churn, of which the following'is a specification. I

The present invention appertains to churns, and aims to provide a novel and improved device of'that character.

It is the object of the present invention to provide a dasher staff or stem engaged through the cover of the churn body or receptacle in a peculiar manner, whereby the dasher or agitator carried by staff or stem within the churn body will be simultaneously rotated and reciprocated, the dasher or agitator being of unique construction whereby its rotation and reciprocation .will effectively agitate the contents of th churn for churning the same.

Another object of the present invention is to provide a novel means for 'operatively connecting a non -rotatable reciprocatory handle with the outer or upper end of the dasher staff or stem, in order that the dasher stafi may be effectively and readily operated when the handle is gripped in one orboth hands and reciprocated.

It is also within the scope of this invention, to improve the structure generally, whereby its utility will be enhanced, and whereby the device will be comparatively simple, durable andinexpensive in construction, as well as being convenient, practical, serviceable and efficient in its use.

NVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a longitudinal section of the churn, portions being broken away, and parts being shown in full. Figs. 2 and 3 are cross sections taken on the lines 22 and 38, respectively, of Fig. 1. Fig. 4 is an enlarged sectional detail of the connec- I dished, as seen in Fig. 1, and provided with a peripheral depending flange or rim 1 adapted to be slipped snugly into the upper end or mouth of thebody or receptacle 1. The cover 2 may be held in place by any suitable means to prevent its accidental detachment. A plug 5 of hard metal is Patented Feb.16, 1915.

soldered or otherwise secured through the center of the top 3 of the cover or cap, and is provided with a slot 6 therethrough. the top 3 of the cover being provided with drain apertures 7 adjacent the plug 5 through which the milk and cream may flow back into the churn fbody if it is raised by the I dasher staff.

The dasher staff comprises a twisted bar or strip 8 forming a screw, and which is engaged through the slot 6 of the plug 5,

whereby the vertical reciprocation of the dasher staff will rotate the same.

The dasher or agitator embodies a cruciform or star-shaped plate 9, preferably formed from sheet metal, and having its ends bent angularly upward to provide the ears 10. The lower end of the dasher staff 8 is secured in any suitable manner through the central portion of the dasher or agitator to carry the vsame. j

In order to operatively connect the handle 11 and dasher staff or screw 8, the upper end of the dasher staff is provided with a shank 11 of circular cross section and which is externally threaded. The handle 11 is preferably constructed of wood and may be of any suitable length, the handle and dasher staff being coaxial and arranged in vertical alinement. A pair of disks 12 are mounted upon the shank 11' of the dasher staff, and a pair of clamping nuts 13 are threaded .upon the shank 11 to hold the disks 12 together, the nuts 13 seating or bearing against the remote faces of the disks 12, and the adjacent faces of the disks having annular ball races 14. A ring 15 is disposed between the peripheries of the disks 12, and its inner side is provided with opposite ball cones 16 cooperating with the respective ball races 14, and two annular series of ball bearings 17 are disposed between the complementing ball races 14 and cones 16 to enable the disks 12 and ring 15 to rotate relative to one another.

The ring 15 is secured to the lower end of the handle 11, and to this end, a pair of arcuate plates 19 are secured to opposite sides of the handle 11 adjacent its lower end, by means of a rivet or other securing member 20 engaged through the plates 19 and the lower end portion of the handle, and the plates 19 are provided with depending arms 21 offset away from each other to provide a fork. The lower ends of the arms 21 are bent angularly toward one another, as at 22, and are engaged within slots or recesses 23 provided in diametrically opposite portions of the ring 15. The arms 21 may be soldered or otherwise secured to the ring 15. In this manner, the ring 15 is rigidly secured to the lower end of the handle 11, in spaced relation therewith, and the ring 15 being disposed between the two sets or series of ball bearings 17, will enable the dasher staff to be reciprocated with the handle, although the dasher staff is free to rotate. The nuts 13 hold the disks 12 together, to thereby prevent their excessive separation, except when the device is separated.

The present device may be employed for churning purposes, in the usual mode, it being noted that when the dasher staff is reciprocated, it will be rotated to thereby impart both a reciprocatory and rotatory movement to the dasher or agitator for thoroughly agitating and churning the contents of the body or receptacle 1. Ihe peculiar formation of the dasher or agitator is of advantage in properly agitating and churning the contents of the churn body, and for enabling the butter to be readily lifted from the churn body with the dasher. The plug 5 provides a durable wear member for the dasher staff, it being noted that the cover or cap is provided with the drain apertures 7 adjacent the plug 5 whereby any milk and cream raised through the slot 6 with the dasher staff, may flow back into the 1,12e,ese

dasher staff, to enable the dasher staff to rotate freely as it is reciprocated.

Having thus described the invention, what is claimed as new is 1. In a churn, a churn body, a cover therefor, a twisted dasher staff engaged through the cover, a dasher carried by the dasher staff Within the churn body, a pair of disks mounted upon the upper end portion of the dasher staff and having annular ball races in their adjacent faces, a handle, a fork attached to one end thereof, a ring secured to the ends of the fork arms and disposed between the said disks, the inner side of' the ring being formed with ball cones, and ball bearings disposed between the respective ball cones and ball races.

2. In a churn, a churn body, a cover therefor, a twisted dasher staff engaged through the cover, a dasher carried by the staff within the churn body, the dasher staff having a shank at its upper end, a pair of disks mounted upon the said shank, a pair of nuts threaded upon the shank to hold the disks against separation, a handle, a ring attached to the handle and disposed between the said disks, and anti-frictional bearings disposed between the said ring and disks.

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

WVILLIAM L. LOGAN.
