PATENT IVILLIAM A. NEVEL AND GEORGE W. FISHER, OF VVILLS POINT, TEXAS.

CHURN-MOTOR.

SPECIFICATION forming part of Letters Patent No. 294,064, dated February 26, 1884.

Application filed March 6, 18E3. (No model.)

.To all whom it may concern.:

lle it known that we, WILLIAM A. NnvnI. and GEORGE W. FISHER, citizens of the United States, residing at VVills Point, in the county of Van Zandt and State of TeXas,have invented certain new and useful Improvements inChurn- Motors; and we 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 the letters and iigures of reference marked thereon, which form a part oll this specication.

Our invention relates to improvements in churn-motors; and it consists in the novel construction and arrangement of parts, as hereinafter described. The machine shown is so constructed that it gives to the dasher a perpendicular long or short stroke, and that it maybe sunk deep or shallow in the milk; and the machine may be run at the greatest speed with but little friction, and without the danger of its parts becoming loosened, and by means of its apron and attachment, hereinafter described, it holds the churn in place.

A, Figure 1, represents an ordinary frame made of wood, about thirty-two inches long and four inches wide,mounted on four legs. In this frame we place two wheels, mounted on proper shafts and working in suitable bearings. The driving-wheel B is about twenty inches in diameter, and the pulley C (hidden from view by the balance-wheel F, but representedl by the circular dotted line) about six inches in diameter. This machinery has a handle, D, and band E, and may be driven by hand or other power.

On the end of the shaft of pulley C, and on the outside of frame A, we rigidly and securely fix a balance-wheel, F, -about eighteen inches in diameter. In this wheel we make three or more screw-holes, 1, 2, and 3. (These holes are distributed over the face of the wheel, because if placed in row the wheel would be weakened, but they are equal distances apart.) Hole lis about two inches from the center, hole 2 about four inches, and hole 3 about six inches, and when the lever is geared to hole 1 it will give the dasher about four inches stroke, at hole 2 about eight inches stroke, and at hole 3 about twelve inches stroke. These holes may be ar- 'firmly to head a".

ranged to give any length of stroke desired. The lever G is about thirty-six inches long, having thumb-screw hole a, rectangular slot b, and square hole c, into which rectangular slot b extends, and in the front end of the lever is 'a perpendicular slit, d, for holding the rod e of the churn-dasherj. llhe upper end, e', of this rod e is flat, and small enough to play freely in slit d, and we make in it a number of holes above each other, so we may regulate its depth into the churn. To secure this lever G in place, we use thumb-screw H and stud I. II is an ordinary thumb-screw, I, Fig. 2, is a double-headed screw, having threaded end i, circular head i', wrist '52, and square head '53. The threads on this screw are cut against the motion of the balance-wheel, F, so that the motion of the same has a tendency to screw down or tighten the screw, rather than loosen it. The motion of the balance-wheel in this machine is forward, and consequently the threads on the screw'are cut right-handed. If the band should be crossed or the gearing cogged, so as to run the balance-wheel back, the threads in the thunib-sc1ew \voi1ld be cut lefthanded. On putting on this lever G, we rst insert the thumb-screw I into hole 1, 2, or 3, according to the length of the stroke we wish the dasher to make, and screw it down This head answers the double purpose of a washer, preventing the side of the balance-wheel from rubbing against the side of the lever, and of giving a rm base for the wrist i2 to rest on, keeping it steady and from wabbling. IVhen this thumb-screw is screwed down, the lever is put on, passing the square hole c over the head i, then drawing the lever back until the wrist i2 is brought into slot b. The rear end ofthe lever is then secured to the rear end of the fra-nie A by means of a thumb-screw, H, first putting a washer between the frame and lever. To this frame Awe attach a removable apron, J, Fig. 3, and chine-brace K,l for the purpose of holding the churn in place. The apron J is attached thus: IVe cnt grooves l Z on the inside of the front legs, opposite each other, and about four or five inches from the feet.- Into these grooves we fit a piece of plank, allowing its front end to extend far enough for the churn to rest on, and we place a leg under this apron, to keep it from sagging. On this apron we IOO secure our chinebrace K. It is made thus: XVe take a piece of plank about an inch thick, make it circular, then saw off a segment of about one-fourth of its circle, which, for the purpose of description, we mark M. In the larger piece we make a socket, and place therein a spiral spring, 7c, and bore two threefourths-inch holes into the block at the dotted lines k, for the insertion of pins k2. rlhese pins, Fig. i, are about one-half inch in diameter, and have heads three-fourths of an inch in diameter. XVe insert these pins k2, head down, into holes 7c. IVe make pieces k3, with holes one-half inch in diameter, and put over the pins and secure them on the plane of the large piece of the chine-brace K. In the smaller piece, M, we have two corresponding holes, and firmly secure the small ends ofthe pins therein. XVhen the churn is placed over this chine-brace, the spiral spring k presses out piece M against the chine of the churn and holds it in place, and when the churn .is removed the heads on the ends ofthe pins keep them from being withdrawn by the pressure of the spring. By making the spring and pins long` enough this chine-brace will brace itself against the chine of any sized churn, and hold it firmly in place.

Having thus described our invention, what we claim as new, and desire to secure by Let? ters Patent, is

l. In combination with the churnmotor, as above described, removable apron J, fitting into grooves on the inside of the front legs of .the frame A, and chine-brace K, consisting VILLIAM A. NEVE-L. GEORGE lV. FISHER. Witu esses:
