SPECIFICATION forming part of Letters Patent No. 471,334, dated March 22, 1892.

Application filed September 11, 1891. Serial No. 405,394. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM E. DEPP, a citizen of the United States, residing at Brookville, in the county of Jefferson and State of Pennsylvania, have invented a new and useful Churn, of which the following is a speciiication.

The invention relates to improvements in churns.

The object of the present invention is to simplify and improve the construction of churns, more especially the means for securing the cover to the body.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a churn' constructed in accordance with this invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a detail perspective view of one of the dasher-blades. Fig. 4 is a detail view of one of the fasteners. Fig. 5 is a detail view of one of the jaws of the same.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a cylindrical churn-body, preferably composed of a barrel and having a cover 2 and provided on its inner face with vertical ribs 3, which act in conjunction with blades 4 of a dasher-shaft 5, whereby cream is thoroughly agitated and quickly converted into butter. The cover 2 is composed of two segmental sections 6 and 7, which are provided in their meeting edges with curved recesses 8 and 9 to form a central bearing-opening for the shaft 5, and the latter has its upper end journaled in the cover, and its lower end is provided with a conical cavity 10, which receives a conical journal 11, extending centrally from the bottom of the churn-body. The section 6 is slightly larger than the section 7, and is provided at diametrically-opposite points on its cur-ved edge with headed lugs 12 and at an intermediate point with a similar lug 13, and these lugs are engaged by an eye 14 and fasteners 15 and are preferably formed by screws. The eye 14 is formed at

cesses

23 and 25.

one end of a plate 16, and it has a curved notch 17 to confine the lug 13, which is inserted in the eye preparatory to manipulating the fasteners. 4

The fasteners 15 are constructed of sheet metal or other suitable material, and each is composed of two

jaws

18 and 19, which are pivoted together by a rivet 20 and are slightly curved throughout their length. The jaw 18 has its end 21 pivoted to the churn-body by a screw or other suitable means, and its other end 22 is formed into a head and is provided with a recess 23. The other jaw 19 has its pivoted end provided with a head 24 and has a similar recess 25, and its other end, which is free, is slightly extended and is curved, and is adapted to be swung over the end 21 of the jaw 18 to confine one of the lugs 12 in the re- The jaws are swung apart to release the lug and allow the section 6 of the cover to be removed.

The sections 6 and 7 iit together to form a central opening for the shaft 5, and the latter is secured to the section 6 by a latch 26, having one end pivoted to the section 6 and its other end formed into a handle and adapted to engage a projection 27, and it is curved intermediate its ends to conform to the shaft and form a bearing for one side of the same. The upper end of the shaft carries a pinion 28, which is arranged to mesh with a drivewheel 29, which is mounted on a standard 30 and is provided with a handle 31, by which the churn is operated. The dasher-blades 4 are gained into the shaft and are arranged on opposite sides of the same and are disposed at an inclination. The blades on one side of the shaft are arranged opposite the intervals of the blades on the opposite side of the shaft, and all the blades have their upper faces corrugated. By this arrangement when the shaft is rotated the lowermost blade tends to raise the cream and throw the same upon the next higher blade, and this blade tends to throw the cream on the one above it, whereby the cream is caused to rise at the center of the churn-body and is thoroughly agitated and butter is quickly produced.

It will be seen that the churn is simple and comparatively inexpensive in construction, is capable of thoroughly agitating cream and IOO quickly producing butter, and that its cover is securely clamped to the body, but may be readily removed when desired.

Froin the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention will be readily understood.

lVhat I claim is- 1. In a churn, the combination of a body provided with a plate having an eye and arranged at the upper edge of the body, a cover having oppositely-disposed lugs 12 and an i11- termediate lug 13 to engage the said eye, and fasteners composed of two jaws pivoted together and arranged to clamp the lug 12 between their pivoted ends, one of said jaws being pivoted to the churn-bod y, substantially as described.

2. In a churn, the combination of a body, a cover provided with oppositely-disposed lugs, and fasteners comprising the jaw 1S, having its end 2l pivoted to the body and provided at its end 22 with a head and with a recess 23, and the jaw 19, having a head 24 and a recess 25 and being pivoted to the end 22 of the jaw 18, said jaws being curved throughout their lengths and being arranged to clamp the lugs in the recesses, substantially as described.

3. In a churn, a dasher provided at opposite sides with blades disposed at an inclination and having their upper faces corrugated, the blades of one side being arranged opposite the intervals of the other blades, substantially as described.

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

lVILLIAM E. DEPP.
