CREANFTESTNG CHURN.

SPECIFICATION forming part of Letters Patent No. 392,865, dated November 13, 1889e Application filed March 23,1888. Serial No. 208,241. (No model.)

To @ZZ whom it may concern:

Be it known that I, BYRON KANABLE, of Marion. in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Cream-Testing Ghurns; and I do hereby 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.

My invention relates to an improvement inV creau1-testing7 churns.

The object of my present invention is to provide a simple, light, and convenient device which may readily be transported from place to place, and furnish a convenient means for quickly churning a sample of cream taken from a cream-venders pail, preferably at the residence of the cream-producer.

Vith these objects in view my invention consistsiu certain features of construction and combinations of parts, that will be hereinafter described, and pointed out in the claims.

The device which is the subject of this invention is one of the essential mechanical features preferably employed to carry into effect a novel process invented by me and which is the subject of another patent. The process alluded to is an improved method of determining accurately aud speedily the amount of butyric oil contained in a sample of cream, so as to ascertain by its proportionate volume the commercial value as a butter-making material of a body of cream contained in a vessel from which the sample was extracted.

Referring to the drawings making a part of this specification, Figure 1 is a side elevation ofthe cream-testing churn, with a test-tube that holds the cream in place on the churn to be agitated by the action of the churn. Fig. 2 is an end elevation of the churning device.

The frame E of the cream-testing churn cousists of an upright metal bracket which has two limbs, E', formed integral with the upper portion, these limbs being curved away from each other and made parallel, so as'to afford a light and Vstiff column, that is attached to or integrally formed upon the top face of the baseplate EZwhich is of sufficient area to properly support the entire mechanism.

, On the upper end of the frame E a horizon` tal cylindrical hub, E3, is formed,which is perforated axially to receive a shaft, m. In order to take up any lostmction which may result from a rapid motionl of the shaft in the supporting-box E3, the latter is longitudinally and axially slotted, as well as the upper portion of the frame E, as shown atf in Fig. 1, and asetbolt, g, is inserted to clamp the separate portions toward each other.

Upon the right side of the frame E a cylindrical stud, C2, is made to proj ect,which is held in place by its integral collar K, bearing on one side of the frame'and clamped thereto by a nut, C', which engages the other side surface of the frame, as shown in dotted lines in Fig. 2. The stud O2 is intended to revolubly support the spur gear-wheel F, thehub C of which is perforated to engage this stud and is held in place by a washer, w, and pinp, as shown in Fig. 2. On the wheel F a crank-handle, O, is attached to afford means for the revolution of the wheel and operation of attached parts.

Upon a projecting end of the shaft m a small pinion, F', is secured,which is of a proper diameter to mesh with the spur-wheel F, and on the opposite extended end of this shaft m a crank-disk, G, is affixed, which latter is perforated at a proper point to receive the crankpin h. (Shown in dotted lines in Fig. 2.)

A spring-bar, H, which is made of elastic material, either wood or metal, is attached to the base-plate E by secured engagement of its lower end with a projecting lug, lo, that rises from the base-plate at a proper point. The length of the spring-bar H is proportioned to the height of the frame E, so that its upper end will extend above the frame to clear it, and on this upper end two clamping-jaws, P P, are

formed,which are elastic and have a tendency to spring apart when unchecked.

The upper extremities, P', of the jaws P are curved to produce clamps, which together are adapted to embrace the cylindrical body of a test-tube, D, as shown in Fig. l; and to retain the tube in place within the clamping-jaws P a cross-bolt, o, and its nuto are made to engage the two jaws on their outer surfaces by insertion of the bolt through perforations made in the jaws P, as shown in Fig. 2. The crankpin 7L of the disk G is inserted through a lon- IOO gitudinal slot, h, (see Fig. 1,) and is held in sliding contact therein by a plate, h', and cross pin t.

From the foregoing description of parts of this churning device it will be apparent that a revolution of the spur-wheel F will rapidly reciprocate the upper end of the spring-bar H and an attached test-tube, D, and, as this tube is adapted to receive a certain quantity of cream and retain it, the vibration of the tube, when it is charged with cream, will rapidly change the cream into butter and buttermilk by the percussive action of the machine, this being the function of the device herein described.

I do not desire to limit the construction of this cream-testing churn to the exact forms herein shown, as it is evident that the same may be slightly varied without a departure from the spirit of my invention. Neither do I Wish to limit myself to the clamped support and churn-agitation of a single test-tube at one time, as it is readily seen that there may be two or more clamps affixed to the top of the spring-bar H to receive and reciprocate at the same time more than one tube, and thus churn the contents of two or more test-tubes by one operation, if it is desired.

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

1. In a cream-testing churn, the combination,with a frame carrying gearing, of a springbar rigidly secured to the frame at one end and provided at its free end with jaws for clamping a churn, the said bar being connected to the gearing at a point between its ends, substantially as set forth.

2. In a cream-testing churn, the combination, with a base-plate, a frame, and gearing supported to revolve on this frame and adapted to vibrate a spring-bar, of a spring-bar and clamping-jaws formed on this spring-bar, substantially as set forth.

8. In a cream-testing churn, the combination, with a frame, a base-plate, a spur gear- Wheel, a pinion, a shaft, and a crank-disk, of a vertical slotted spring-bar, clamping-jaws for this spring-bar, and a means of rotating the gearing to vibrate the sp ring-bar, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing` witnesses.

BYRON KANABLE.
