JAMES E. GIBBS, OF BRIDGEWATER, VIRGINIA.

CHURN-DASHER.

SPECIFICATION formingpart of Letters Patent No. 568,086, dated September 22, 1896. Application filed July 11, 1896. Serial No. 598,823. (No model.)

To all whom it may concern.-

Be it known that I, JAMES E. GIBBS, a citizen of the United States, and a resident of Bridgewater, in the county of Rockingham and State of Virginia, have invented certain new and useful Improvements in Ohurn- Dashers and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a central vertical section through churn. Fig. 2 is a section on line 00 m, Fig. 1; and Figs. 3 and 4 are plan views of the two ratchetrings E and F, respectively.

This invention has relation to that class of churn-dashers which are provided with oblique blades adapted to rotate as they are reciprocated, means being provided forsecuring them against rotation 011 the downstroke, While permitting them to turn freely on the upstroke.

The object of the present invention is, mainly, to obviate the use of metal bearings or fittings for the dasher or its blades, such use being objectionable for the reason that unless the greatest care is exercised in keeping them clean the cream is discolored by contact therewith.

With this and other minor objects in view the invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A indicates a churn-body, andB the cover thereof, which is formed with the usual central circular aperture for the dasher-rod O. Said dasher-rod, with the exception of its handle portion Q, is of squared form in cross-section, its lower end portion being formed with a tenon c, to which is fitted the oblique radial blades D. Secured to the outside of the cover around the central aperture is a ratchet-ring E, having a circular opening coincident with the said aperture and designed to permit the dasher-rod to play freely therethrough.

F is a second ratchet-ring of complementary form, but which has therein a squared opening which receives the dasher-rod.

. F is a cap or casing which is placed over and around the ratchets, being secured to the fixed ratchet or to the cover. The purpose of this cap or casing is to permit the upper ratchet from moving too far upward when the dasher is raised.

The handle portion C of the dasher-rod is made in a separate piece, and is connected to the rod proper by means of a swivel-coupling, which may be of the character shown in the drawings; that is to say, the lower end of said portion is provided with a sleeve G, which is arranged to rotate on a headed pin or screw 9, secured in the upper end of the rod proper.

The two ratchet-rings are to be made of hard wood, and the cap or casing F may also be of wood. The top of the cover 13 is preferably cupped out, as indicated at b, around the said rings.

The operation is as follows Upon the downstroke of the dasher the ratchet F looks with the ratchet It and the dasher is held from rotation. Upon the upstroke the ratchets disengage and the dasher, dasher-rod, and ratchet F all rotate. The handle portion 0, however, which is held by the handles does not rotate. Usually heretofore the blades were made to rotate on a suitable bearing carried by the rod, which did not itself turn. This bearing, however, must be of metal to secure proper action, and is obviated by the construction and arrangement described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a churn-body and its cover, and with a ratchet-ring fixed to the outside of the latter aroundits central opening, of the dasher having the oblique blades fixed to its lower end, and formed with a squared portion, which works loosely through the said ratchet-ring and cover, a second and complementary ratchet-ring on the said rod, and having a squared opening through which said rod works, and means for limiting the vertical movement of said second ring, substantially as specified.

2. The combination with a dasher-rod of squared form, having a dasher composed of oblique radial blades fixed thereto, of a said rod by a rotary or swivel coupling, subratchet-ring having a squared opening for stantially as specified. 10 said rod, a second ratchet-ring designed to In testimony whereof I afiix my signature be fixed to the churn-cover and to lock with in presence of two witnesses.
