JAMES 1t. HOLDER, OF CLAYTON, TEXAS.

CHURN.

Specification of Letters Patent.

Patented May 25, 1909.

Application filed November 11, 1908. Serial No. 462,087.

T all whom it may concern:

Be it known that 1, James R. HOLDER, citizen of the United States, residing at Clayton, in the county of Panola and State of Texas, have invented certain new and useful Improvements in Churns, of which th following is a specification.

The object of my invention is to provide a simple and efficient power mechanism for churns and is more particularly adapted for use in connection with that type of churn wherein a vertically reciprocating dasher is employed.

The invention comprises essentially a frame provided with suitably arranged sections in which a power wheel is mounted, and pulleys also mounted in the frame driven by belts and connected to the power wheel for imparting reciprocating movement to a slide head operating in guides carried by the frame and to which a dasher is connected, the pulley also imparting rotary motion to a fan suitably located and mounted in the frame and adapted to temper the contents of the churn and promote the churning efliciency of the power mechanism.

The frame is constructed and arranged to permit the removal of any of the several sections comprising the power mechanism, also to permit the churn receptacle to be readily introduced or withdrawn at any stage of the churning operation and to ascertain at intervals the condition of the contents of the receptacle without the removal or disconnection of the power mechanism.

For a. full uinlerstanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of the frame and power mechanism; Fig. 2 is a vertical sectional view on the line of Fig. 1; Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 1; and, Figs. 4 and 5 are eI1 larged detail illustrations of the dasher and fan wheel casing.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates a frame structure comprising upper and lower sections 1 and 1 respectively secured to standards or uprights 2 and l l l provided with suitably located cross braces, the power mechanism being mounted in said frame. A driving shaft 3 is journaled in the upper portion of the frame at one end as shown at 4 and operated by ower from any convenient source as by a beTt, (not shown), connected with a pulley 5 carried by the shaft or by hand power applied to the handle 6.

The numeral 7 designates a power wheel carried by the shaft 8 and constitutes that portion of the churning mechanism from which power is transmitted to the crank shaft 8, said crank being journaled in the upper portion of the frame as shown at 9 and connected. to said power wheel by means of a pulley 10 carried by said shaft and a belt 11 passing over said pulley and power wheel. The oppositely arranged vertical guides 12 are secured to the frame 1 in alinement with the crank shaft 8 and connected at both ends by horizontal frame members 18 in which. oppositely arranged vertical guide rods 14 are secured. These guide rods are in the form of straight bars circular or non-circular in cross section, arranged in parallel relation respectively and are designed to form guiding means for the reciprocating cross head 15. Said rods extend through openings in the upper and lower sections of the cross head and by reason of such. an arrangement said cross head in its reciprocating n'iovement during the churning operation is maintained in a fixed vertical plane. The reciprocating cross head may be of any desired construction or formation and as shown preferably consists of upper and lower spaced members to which an operating pitman 16 is pivotally secured at the upper end as shown at 17 and connected to the crank 18 on the crank shaft 8 as indicated at 19. The reciprocating cross head constitutes the carrying member for the reciproeating dasher rod 20, one extremity of which is secured to the lower end of said cross head as shown at 21, and a dasher 22 comprising overlapped dasher sections of cross formation is rigidly secured to the opposite extremity. The lower end of the dasher rod carrying the dasher is designed to extend within a churn receptacle 23 and upon reciprocatory movement of said rod occasioned by motion transmitted to the cross head, the contents of the receptacle is agitated thus effecting the churning operation. To increase the elliciency of dasher or ag1- tator 22 and to secure the desired effect upon than the contents of the receptacle,-the sections are overlapped to form a cross (Fig. 4:) and provided with notches or slots 24 at their opposite extremities.

The numeral 25 designates a fan shaft journaled in the frame 1 as indicated at 26 and a fan wheel 27 carried by said shaft is rotated by a belt 28 operating over pulleys 29 and 30 carried by the shaft 25 and driving shaft 8 respectively. The fan is designed to regulate the tem erature of the contents within the receptac e 23 and is operated in connection with the ower mechanism continuously or at interva s, its use being determined by the conditions under which the churning operation is conducted and controlled by the manipulation of the belt 28 operating over the pulleys 29 and 30. A fan casing 31 secured to the frame 1 and surrounding said fan Wheel is provided with a flared mouth portion 32 positioned in such manner as to direct the force of the fan wheel when operated against the side of the receptacle and secure the desired effect upon the churning material as may be expedient to secure the best results in cooperation with the reciprocatory churning operation of the power mechanism. Oppositely arranged vertical supports or standards 33 inortised in the upper frame section 1 and adjustably secured therein by set screws 34, are located on said frame intermediate of the drive wheel 7 and pulley 10, and an idler 35 journaled in said supports is designed to regulate the tension of the belt 11 upon proper manipulation of said supports to move the idler into or out of an operative position.

With the arrangement of the several parts as shown, the operation is as follows :-The driving shaft 3 is o aerated by the handle 6 or from any source of power transmitted to the pulley 5 by a belt (not shown), and when so I operated the crank shaft 8 having a belt connection with the drive wheel 7 is caused to revolve and the reciprocating cross head 15 carrying the dasher rod and dasher is given the necessary reciprocatory movement to agitate and churn the contents of the receptacle to the desired consistency. The fan wheel 25 also having a belt connection with the driving shaft is simultaneously operated with the power mechanism when it is desired to temper the contents of the receptacle 23, and as before stated, the fan is designed to overcome certain atmospheric or other temperamental conditions detrimental to the speedy coagulation of the material under operation.

The simplicity of construction of the cooperating sections and the practical merit of the power mechanism will be manifest, and as will be understood a plurality of churns may be operated by increasing the frame dimensions to accommodate a series of reciproeating cross heads operated from a crank shaft common to all, and properly spaced to permit the receptacles to be introduced and withdrawn from the frame.

Having thus described the invention, what is claimed as new is:

A churn of the character described, comprising a churn receptacle and frame, a driving shaft journaled in the frame, a belt wheel mounted thereon, a crank pulley ournaled in said frame and driven by a belt from the driving shaft, vertical guides secured to said frame in line with said crank shaft, oppositely arranged guide rods carried by said guides, a reciprocating cross head operating between said guides and guided in its reciprocatory movement by said guide rods, an operating pitman connected to said crank shaft and cross head, a reciprocating dasher rod connected to said cross head and deriving its motion therefrom said dasher rod having a dasher secured to one extremity for agitating the contents of said receptacle, and a fan journaled in said frame and having a belt connection with said driving shaft indepem ent of the connection to the crank shaft and adapted to temper the contents of said receptacl'e during the churning o oration.

In testimony whereof I ai x my signature in presence of two witnesses.
