' SPECIFICATION forming part of Letters Patent No. 531,204, dated December 18, 18x94.

Application filed August 14, 1894. Serial No. 520,317. (No model.)

To all whom it may concern:

Be it known that I, JOHN A. MADDOX, a citizen of the United States, residing at West Union, in the countyrof Adams and State of Ohio, have invented a new and useful Ohurn,

of which the following is a specification.

The invention relates to improvements `in l churns.

The object of the present invention is to 1o improve the construction of churns, and to provide a simple and comparatively inexpen sive one, capable of rapidly producing butter, and adapted, after the operation of churning is completed, to separate the butter, and to elevate the same to the top of the churn, to facilitate its ready removal from the churn body.

The invention consists in the construction and novel combination and arrangement of zo parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended. In the drawings: Figure 1 is a perspective view ofa churn constructed in accordance z 5 with this invention, the dasher and the butter lifting receptacle being elevated. Fig. 2 is a central vertical sectional view of the same, the parts being in position for churning. Fig. 3 is a detail perspective view illus- 3o trating the manner of detachably swiveling the butter lifting receptacle to the lower end of the dasher shaft. Fig. 4 is a detail' sectional view of one side of the churn, illustrating the construction of the slides and the Ways Like numeralsjof reference indicate corresponding parts in all the figures of the drawings.

1 designates a rectangular churn body, pro- 4o vided with legs 2 and having a cover 3, connected with the body by opposite `depending slides 4 arranged in'vertical ways 5 of the body. The ways 5 are preferably formed by vertical grooves covered by strips 6 of sheet metal,- or the like; and when the churn is open the cover is elevated, and the slides are moved vertically in their ways, by means hereinafter described.

The cover 3 is provided with a hinged section 7 to permit access to the interior of the 5o churn without elevating the cover; vand it has a central opening in which is -journaled avertically disposed dasher shaft 8, depending from the cover and carried by the same and provided with oppositely disposed vertically arranged perforated dasher blades 9. The dasher blades 9 are rotated in the body to effect the operation of churning; and the dasher shaft is extended upward through the cover 3, and is'provided with a collar 10, located 6o upon the upper face of the cover. The upper end of the dasher shaft is provided with a horizontally disposed bevel pinion 1l, which meshes with a bevel gear wheel 12,carried by a swinging frame 13and adapted 6 5 to mesh with the bevel pinion, as illustrated in Fig. 2 of the accompanying drawings, when the swinging frame is in a vertical position. The swinging frame is hinged at its bottom to one side of the churn body. It may be of 7o any desired construction; and it is provided at its top with a bearing 14, in which is journaled a drive shaft 15, carrying a crank wheel 16 at one end and having the beveled gear wheel 12 at its other. This frame 13, which 75 may be provided with arms 17 is connected at opposite sides by cords 18, or the like, which are arranged in horizontal grooves 19 at the upper ledges of the churn body, and which pass over the pulleys 2O at the irner termi- `30 nals of the grooves, and are secured at their lower or inner ends to the bottoms of the vertical slides 4. When the frame 13 is swung downward, it draws the cords,which are attached to the ends of the arms 17, outward, and thereby carries the slides upward and elevates the cover and the dasher mechanism carriedyby the same. As the swinging frame is moved upward and inward toits normal vertical position, the cover andthe dasher 9o mechanism descend within the churn body.

A rectangular receptacle or strainer 21 is detachably swiveled to the lower end of the dasher rod, and is carried by the cover 3 in its upward movement; and itconforms to the configuration of the churn body, and strains and collects the butter, and conveys the same to the top of the churn body. The receptacle or strainer is provided at its bottom with perforations, and has sides or llanges; and it is provided with a centrally arranged vertically disposed sleeve 22, receiving the lower por tion of the dasher shaft and provided at its top with an annular flange. The lower end of the dasher shaftis reduced to form a shoulder 24, against which the flange 23 bears; and the sleeve is detachably swiveled to the shaft by a pivoted catch 25. The pivoted catch 25 consists of a stem and a horizontal arm 26, arranged at the bottom of the stem, and provided intermediate of its ends with a semicircular bend, which engages the sleeve below the ilange thereof, and thereby holds the sleeve on the shaft. The adjacent inner edges of the blades are recessed to clear the pivoted catch and the stem of the latter is provided intermediate of its ends with an eye to receive the pivot 27. After the butter has been separated and strained, it is conveyed to the top of the churn body by the rectangular receptacle or strainer, from which the butter may be readily removed; and the butter lifting receptacle or strainer may be detached if desired.

The slides 4 are provided at one edge, adj acent to the cord, with a groove 2S to receive the same, and to prevent the cord from being unnecessarily worn by friction. The churn body is provided at one side, near its bottom, with a discharge opening 29, and it has a spout 30; and during the operation of churning a plug 31 is fitted in the discharge open- 1n g.

The legs 2 may consist of strips of metal secured to the bottom of the churn body and having their terminals bent downward and outward at a slight inclination, as shown. The swinging frame is provided at its bottom with a hinge leaf secured to the churn body and connected with the upper portion of the frame by a pintle.

It willbe seen that. the churn is simple and comparatively inexpensive in construction, that it is adapted to produce butter rapidly, and that after the operation of churning has been completed, the butter is readily separated, strained, and conveyed to the top of the churn body to facilitate its removal.

Changes in the form, proportion, and the minor details ot construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

l.
