SPECIFICATION forming peut of Letters Patent No. 360,184, dated March 29, 1887.

Application filed June 13. 1886.

Serial No. 206,001. (No modul.)

Texas, have invented a new and Improved Motor for Ghurns, of which the following is a full, clear, and exact description.

My invention relates to the construction of a cheap, durable, and efficient churn-power which may be placed in any convenient posivtion and used in connection with the ordinary form of vertically-reciprocating dasherchurn.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the figures.

Figure 1 is a"front view of my improved form of churn-power, and Fig. 2is aside view of the same, in partial section, parts being broken awayto disclose the construction. Fig. 3 is a horizontal section taken on line x a" of Fig. 2.

In building such a churn-power as the one illustrated in the drawings above referred to, I provide a main frame, 10, that is preferably about twelve feet in height, and provided with a centrally-arranged toothed rack, 1l., and a grooved sheave or pulley, 12, said shcave or pulley being mounted above the upper crosspiece of the frame 10. A sliding frame, 13, provided with a platform, 14, is guided by ways formed in the main frame 10 by parallel strips 15, that are secured to the inner faces of the vertical posts of the said main frame, the vertical posts of the sliding frame 13 riding between said strips 15, a rope or chain, 16, extending upward from the frame and over the sheave 12, and a connterbalancing-weight, 17, being suspended from the chain or rope 16.

A number of shafts, preferably four, as shown at 20, 21, 22, and 23, are mounted in proper bearings carried by the frame 13, the shaft 20 being provided with a pinion, 24, that is mounted upon said shaft, and held from turning thereon by a feather; or the shaft may be squared and the socket in the pinion correspondingly formed, this construction being adopted in order that the pinion may be moved into and out of engagement with the rack 11.

In addition to the pinion 24, the shaft 20 carries a large gear, 25, which gear is fixed to the shaft 20 and meshes with a pinion, 26,

carried by the shaft 2l, said shaft also carrying a fixed gear, 27, which meshes with apinion, 2S, that is carried by the shaft 22, upon the opposite end of which shaft 22 there is a large gear, 29, engaging with` a pinion, 30, on the shaft 23. The shaft 23, as shown, is mounted in forwardly-extending arms 3l, and upon one end carries a bevel-gear, 32, which meshes with a corresponding` bevel-gear, 33, carried by a vertical shaft, 3l, that is mounted iu proper bearings that arccarricd by the platform 14 and one of the arms 31.

' Upon the shaft 34 there are arranged fans or' wings 35, that are carried by a sleeve, 36, which sleeve is held to the shaft by a setscrew, 37. The shaft 23 is a crank-shaft, and to its crank 38 there is connected a connecting-rod, 39,'which extends upward to engage with the upwardly-extending arms 40 of a divided rock-shaft, 41; or, if preferred, the rockshaft 41 could be made in a single length and be provided with a single forwardly-extending slotted arm. The arms 40 are provided with a number of apertures, 2, and the shaft 41 is provided with a rearwardly-extendiug lever, 43, which carries an adjustable weight, 44.

From the construction described it will be seen that if the frame 13 is moved upward, and its pinion 24 brought into engagement with the rack 11 of the stationary frame, in descending the crank-shaft 23 will be rotated through the medium of the gearing intervening between the pinion 24 and the said crankshaft, and it will also be secu that-as the crankshaft is revolved motion will be imparted to the shaft 41.

In practice the dasher-shaft of a churn, 51, is secured between the arms 40 of the shaft 41, the throw of the dasher being lengthened or shortened to suit the peculiar requirements of the case by connecting the flasher-shaft to the arms 40 at varying distances from the shaft 41, it being of course understood th at this connection is made by a pin passed through some particular pair of the apertures 2, and that the farther the aperture is from the shaft 41 the greater will be the throw of the dasher. After the proper adjustment has been secured the frame 13 is raised to the top of the frame 10, the pinion 24 being at this time disconnected from the rack; but when the frame 13 has been moved to the top of the frame 10 IOO the pinion 2l is brought into engagement with d the rack 11,'aud the frame I8 is allowed to move slowly downward, the force ofthe fall being controlled and governed by varying the Weight of the counter-balance 17. As the frame 13 descends the dasher will be vertically reciprocated and the cream or milk will be churned.

The fans 35 are designed to prevent the accumulation of ilies upon the top of the churn, and should be adjusted so that in revolving they will create a current of air in a plane parallel with the said churn-top.

Although I have described a specific construction of gearing, it will of course be understood that the number of shafts and wheels could be varied, and that any other proper form ot' auxiliary gearing could be employed instead of the form which I have specifically described.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is- 1 The combination, with a Inain frame provided With a rack, of a sliding frame, a counter-balance connected to the sliding frame by a rope or chain which passes over a sheave`
