MEANS FOR OPERATING CHURNS.
SPECIFICATION forming part of Letters Patent No. 436,604, dated September 16,1890.
Application filed March 31, 1890.
T0 @ZZ whom it may concern,.-
Be it known that I, LINDOEE H. JAMES, a citizen of the United States, residing at Vanceburg, in the county of Lewis and State of Kentucky, have invented certain new and usefullmrpovements in Means for Operating Churns; and Ido 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.
This invention relates to certain new and useful improvements in single dasher reciprocating-churns; and it consists substantially in such details as will hereinafter be more particularly d escribed,and speci ically pointed out in the claim.
Letters Patent No. 382,163 were granted lne on the 1st day of May, 1888, for an improvement in ch urns, and wherein I resort-ed to the use of a single vertical dasher operated to reciprocate by means of suitable pulleys, belt, and hand-levers. In the practice of the invention covered by said Letters Patent I have found that the belt or band frequently becomes stretched, and occasions the loss of much time and labor in taking up the slack by which to enable the churn to be worked.
The object of the present invention is to provide means for tightening the belt or band which operates the dasher, substantially as will hereinafter be more fully understood when taken in connection with the accompanying drawings, wherein- Figure 1 is a viewin perspective of a churn embodying my improvements, and Fig. 2 is a vertical sectional elevation thereof.
Reference being had to the several parts by the letters marked thereon, A represents a vertical standard supportedV by the base ct, the same having projecting therefrom the two brackets b b, which guide and support the vertical dasher B. The standard is provided with an opening c, in which the pulley d works, and on the dasher is a corresponding pulley e, the operating-band g passing around Serial No. 346,003. (No model.)
these two pulleys, as shown, and having its ends secured to the two vertical operating handlevers. The hand-levers have their working bearings ou the studs h h, which pass through the two diagonal braces t' i, extending from the sides of the vertical standard, down to or near one end of the base, Where they are properly secured.
The devices which I resort to for the purpose of keeping the belt tight or taut consist of a ratchet C secured to the base, as shown, a hinged arm L extending upwardly from the end of the base, and a pawl M pivoted between the sides of an opening o formed in the arm near its upper end. A small band or cord p passes around a pulley q, workin g in the anni, and has its ends secured to the operating hand-levers N, and it will be evident from the construction shown and explained that when the hinged arm is drawn outwardly the hand-levers will be drawn backwardly and thereby tighten the main band which operates the dasher. As the hinged arm is carried 0utward,the pivoted pawl will follow the same and take into the teeth of the ratchet, so as to hold the arm in Whatever position it may be brought.
From the foregoing description it will be seen that I have provided a churn of very simple construction, and one that is both cheap to manufacture and easy to operate.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a churn, the combination, with a vertical dasher and an operating-band and handlevers, of a pawl and ratchet, a hinged arm, and a cord connectingv said arm and handlevers, substantially as shown, and tor the purpose described.
In testimony whereof I affix my signature in presence of two witnesses.
LINDORF H. JAMES.
