JOHN THEODORE URBACH, OF WVESTON, WEST VIRGINIA, ASSIGNOR OF ONE-HALF TO HARRY W. LIGHTBURN, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 496374, dated May 2, 1893.
Application filed February 6,189& Serial No. 4:6l,240 (No model.)
To all whom it may concern:
Be it known that I, JOHN THEODORE UR BACH, a citizen of the United States, residing at Weston, in the county of Lewis and State of West Virginia, have invented certain new and useful Improvements in Churns; and I do hereby declare the following to be afull, 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 has relation to improvements in churns and it consists in the Construction and novel combination of parts all as will be hereinafter more f ully explained and more particularly pointed out in the appended claims.
The annexed drawings to which reference is made, fully illustrates my invention, in which Fi gure 1, represents a vertical sectional view of my improved churn. Fig. 2, is an enlarged detail view of the vertical bars, taken on tra ns verse line w, w, Fg. l. Fig. 3 is a detail view showing the rack and bar 13, and Fig. 4 is a face View, in detail of the stationary bar.
Referring by letter to the accompanyng drawings A, designates the churn body, having the lid or cover a provided with the usual central perforation, through which the dasher rods pass. y i
B, B', indicate two vertical rods which slide one upon the other; the rod B, is fixed or stationary to the churn by and adjustable by means of the bracket b, hereinafter explained. This rod B, extends from the bottom of the churn, as at c upwardly and is bent at its upper'end, the downwardly projecting end dserving as a bearing for the shafts e andf. and said bent portion serves as a handle for lifting the dashers and rods from the churn body.
e represents a shaft which has its hearing in the rod B the outer end of which is provided with a gear wheel g having a handle h and f indicates a crank shaft; one end of which is provided with a fly wheel i, and the opposite end thereof has secured to it a pinion j which en gages the gear wheel g aforesaid. Connected to the crank of this shaft f is a pitman K, the lower end thereof is pivoted to the upper end of the vertically movable bar B', as at Z.
On top of the cover of the churn body is secured a bracket b, the vertical portion of which partly surronnds the two rods, as shown' in dotted lines as at m while the lower portion, grasps the rod B, and by means of the thumb screw n, which is screwed up, binds or secures said rod to the bracket and holds the same firmly in place. The lower end of the movable rod is bent at right angles and fiattened as at o, forning a dasher, having perforations and said rod is provided with a rack or teeth p on its inner face, which engage a pinion q, seated in bearing 1' in the stationary rod B. This pinion is arranged on a shaft, having its bearing in said rod, is provided with two dasher blades s, s, which are preferably perforated and a loop t, on the rod B, and surrounding the rod B' serves to keep the two rods in close relation to one another. Thus it will be seen from the above description, that the dasher, rods and Operating mechanism can be readily adjusted to different sized churn bodies, simply by the operator loosening the thumb screw and adj usting the rods thereto when the thumb screw is again tightened, thereby holding said rod B in a fixed position and the extended ends of the bracket as shown in dotted lines serve to guide and hold the movable bar or rod in place in its up and down movement. It will be further observed that when the operator turns the crank handle, motion is given to the crank shaft through the medium of the pinion meshing with the gear wheel, and through the medium of the pitman the movable rod is given a vertical sliding movement, and by means of the rack thereon, causing the pinion to revolve, first in one direction, in its upward movement and in a reverse direction in its downward movement, thereby causing the dasher blades to revolve first in one direction and again in the opposite direction, at the sane time, the lower blade on the end of the movable bar has an up and down motion, and is agitating the Cream in the body and assisting the two revolving blades, in churning, and a churn as herein described is easily taken apart for cleaning, can be adjusted to difierent sized churns, and is durable, easilyoperated and at the same time cheap to manufac ture.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In combination with the churn body of the stationary and movable rods. the stationary rod held in the churn by means of the bracket b, the upper end of said rod being bent to form a loop and adapted to form bearings for the Operating meehanisn, the bracket b Secured to the churn cover, and provided with a thumb screw whereby the stationary rod is securely held in place. I
2. The combination With the stationary rod having the gear or pinion and blades on its shaft and Operating mechanisn described of the movable bar having the teeth or 'ack and a dasher blade at its lower end, bent at right angles and forned integral therewith, substantially as described.
JOHN THEODORE URBACH.
