Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed January 23,1906. Serial No. 297,443.

To all 1012,0171, it may con/007%:

Be it known that I, GOLLADAY LAKE, a citizen of the United States, and a resident of Memphis, in the county of Shelby and State of Tennessee, have invented an Improvement in Churns, of which the following is a specification.

My invention is an improvement in that class of churns which are provided with vertical rotary dashers that are operated by a horizontal shaft arranged above the churnbody and suitably geared with the dasher.

The details of construction, arrangement, and operation of parts are as hereinafter described, the features of novelty being specifically indicated in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my improved churn, a portion being broken away to show the construction of the dasher. Fig. 2 is a central vertical section of the churn. Fig. 3 is a perspective view of means for detachably securing the driving-shaft to the supportingstand ards.

The body A of the churn is a cylinder constructed of sheet metal. The conical cover B is provided with a pendent flange b, which embraces the upper end of the body A, and is provided with a central opening for reception of the upper journal of the dasher rod or shaft C. The lower end of the shaft is stepped in a block a, secured to the bottom of the churn-body. The dashers D, of which there may be one or more, are formed of blades set at an inclination similar to the blades of a marine propeller and forming integral attachments of hubs cl, that are adapted to slide easily on the dasher-shaft C.

The dashers D are clamped to the shaft at any desired pointthat is to say, any desired distance from the top or bottom of the churnbody or from each other-by means of clamp-screws (1, whose points enter a longitudinal groove 0, formed in the dasher-shaft. It will be seen that the dashers are not only adapted for vertical adjustment, but may be removed from the shaft C without difficulty.

Upon the upper end of the dasher-shaft C is mounted a bevel-pinion E, the same being detachably secured by a nut c. This pinion meshes with a small bevel-gear F, which is clamped on a horizontal rotatable drivingshaft G, the same having its bearings in the upper ends of vertical standards H and H. These standards are supported upon the body A of the churn, but adapted to be easily detached therefrom when required. They enter keepers a and 0. that are secured to the sides of the churn-body at diametrically opposite points. To each of the lower keepers a is secured a spring-hook I, the same projecting upward and the shoulder of the hook being turned inward and adapted to engage shoulders h, formed in the outer sides of the standards H H. It will be seen that the keepers a and a of each pair being in vertical alinement with each other and with notches 1), formed in the radial flange of the cover B, the standards H and H may be readily inserted therein and will automatically engage the hooks 1, whereby they will be held firmly in place while in use; also, that they may be readily detached by springing the heads of the hooks I outward, as indicated by dotted lines, Fig. 2.

One end of the driving-shaft G is journaled in the standard H, and the other is journaled in the standard H and extended beyond the same, where it is provided with a hand-crank J. To provide for convenient detachment of the shaft G from the standards, the standard H is provided at the top with abearing, the upper portion of which is formed by a block h, (see Fig. 3,) the block having a flange adapted to enter the circumferential groove in the shaft, as indicated in Fig. 2. The block is pivoted at 72/ and its free end provided with a shoulder h, adapted to engage a spring-hook h, that is secured to the standard and arranged in vertical position. It is obvious that by springing back the head of the hook h the block it may be raised for disengaging the shaft and its gear F when required.

One end of the shaft G enters a socket in the standard H and may be readily withdrawn therefrom. It will be noted that the large bevel-gear F is between the bevel-pinion C and the right-hand standard H. Consequently when the block it is released from the catch it the shaft, with the gear F,may be readily removed, since the location of the said gear F permits it to move away from the pinion.

The apparatus is applicable not only for churning, but for mixing various materials, such as paint, cream, paste, powders, and drugs.

a What I claim is- 1. The combination, with a churn-cover, a

body having'guides at opposite points and spring-catches attached to such guides, of a vertical rotatable da'sher-shaft journaled in the cover, vertical standards adapted to enter said guides and automatically engage the said catches, a horizontal driving-shaftjour: naled in the upper ends of'the standards, and bevel-gears applied to the dasher and driving-shaft and meshing in the manner described.

2. The combination, with a churn-body having side keepers and sprin hooks arranged as described, of vertica' standards provided with shoulders adapted to engage the said hooks when the standards are inserted in the keepers, a cover having its rim provided with notches for reception of the standards, a horizontal shaft arranged and held detachably in the upper ends of the standards, a rotatable dasher-shaft whose upper end is journaled in the cover of the churn, and bevel-gearing for operatively con- .device applied to the last-named standard and comprising a pivoted block and a spring-hook adapted to engage its free end, and bevelgearing comprising a wheel and pinion applied to the respective shafts, the wheel being arranged on the side of the pinion farthest from the standard having the socket, as and for the purpose specified.
