C H U R N SPECIFICATION forming part of Letters Patent No. 452,251, dated May 12, 1891.

Application filed August '7. 1890. Serial No. 361,244. (No model.)

To all whom it may concern:

Be it known that I, OLLIE E. BELL, a citizen of the United States, residing at Derby, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Motors; and I do hereby declare the following to be a full, clear, and eX- act 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 churns; and it consists more particularly in means for supporting the same while being revolved, as will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a sectional elevation of my new and improved churn-motor. Fig. 2 is a perspective View of the same. Fig. 3 is an end view.

The same letters of reference indicate corresponding parts in all the figures.

Referring to the several parts of the invention by letter, A indicates the main supporting-frame of the motor, upon one end of which is mounted in a frame A the three transverse shafts B O D, carrying upon them the train of intermeshing wheels and pinions B O O" and D D" D. I employ no springs whatever in connection with this train of intermeshing wheels and pinions; but upon the main wheel of the shaft B is secured a drum E, around which is wound a rope F, the other end of which is permanently secured to the frame A, as shown. On this rope is suspended a weight G, the rope passing through a ring H at the top of the weight; and it will be seen that when the rope has been wound upon the drum E by turning the axle B that the Weight of the weight G will unwind the rope, thereby turning the drum E and with it the shaft B and the train of intermeshing wheels and pinions withoutthe use of springs, and as the large main wheel 13 meshes with the pinion G on the second shaft 0, and the wheel C" on this shaft in turn meshes with the pinion D on the third shaft, it will be seen that the third shaft D will be revolved rapidly for a great number of revolutions for each single revolution of the outer shaft B.

H indicates my cylindrical churn, which is formed with the bottom flange 7t and the In operation a strainer is first placed in the churn, consisting of a circular plate L, formed with apertures Z and having a long flattened handle L, the hooked upper end L of which fits over the upper edge of the churn-body. The cream is placed in the churn and the cover H fitted on,when the end spindles are placed in the bearings of the supportingbrackets and the spring-arms K" are caught over the bottom flange of the churn. WVhen the churn is placed in this position, its end pinion I will mesh with the pinion D on the shaft D. The rope is now wound upon the drum, as before described, when the weight will unwind the rope, thus revolving the train of wheels, and through the pinion D" revolving the churn with great rapidity. When the churning is completed, the churn is lifted off from the supporting-brackets, the spring-arms K permitting of its ready removal, and the cover is then removed from the top of the churn and the strainer lifted out by its handle, raising the butter with 1t and leaving the buttermilk in the lower part of the churn.

In order to cause the churn to be revolved at a uniform rate of speed I employ the following devices: In vertical bearings A" of the frame A is supported a governor-rod 0, having upon its upper end the usual governor-arms 0', weighted at their ends. The lower end of this rod is squared and passes through the squared central aperture of pinion P. Upon the shaft D is secured the crown-wheel D the teeth of which mesh with the pinion P. It will now be seen that in operation as the shaft D revolves the governorrod will be caused to revolve with it, and when an unusually high rate of speed is reached the weight-arms of the governor, rising as they revolve, will raise the governorshaft. Thelower end of this shaft ispivoted to the inner end of a brake-lever Q. This brake-lever is centrally pivoted, and its outer end passes immediately above the main shaft 13. \Vhen the speed of the mechanism be come too great and the governor-shaft is raised, itwill press the free end of the brakelever down upon the outer shaft 13. The lever, thus operating as a brake, will retard the movement of the main shaft and thus reduce the speed to its normal limits. As the speed decreases, the governor-arms will, of course, fall, lowering the governor-shaft and raising the outer end of the brake-lever.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood.

It will be seen that my motor is simple, strong, and very durable in construction, as I dispense entirely with all springs for operating it.

The motor can be used for many other purposes besides churning, to which l do not, of course, limit myself.

llavingthus described my invention, \vhatl elaim,and desire to secure by Letters Patent, 1s-

The combination, with a chnrn-h0dy,of the end spindles secured thereto, one of said spindles having an ordinary cog-Wheel, the supporting-frame having the recessed vertical standards adapted to receive the end spindles of the churn, one of the said standards having the curved spring-arms adapted to lit over the end of the churn-body, and a suitable motor having a gear-wheel meshing with the cog-Wheel on the ehurn-spimlle,substantially as set forth.

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

()L'LIE 1C. HELL.
