SPECIFICATION forming part' or Letters Patent No. 603,381, dated May a, 189s.

' Appncation Elea Juiy 9,1897. sentirme-13.991; (Nomad.)

`Ilo all whom it may concern:

`Be it kn own that I, FLAvIEoUs J. HOGE, a citizen of the United States, residing at Birchwood, in the county of Jamesand 'State of Tennessee, have invented anew and useful4 Churn, of which the following is a specification.

My invention relates to churns, and has for its object to provide asimple, compact, and efiicient construction and arrangement of parts wherein the supporting-frame is adapted to fold when not'in use for compactness in transportation and storing,'and, furthermore, to provide an efficient construction of dasher mechanism whereby the cleansing thereof is facilitated. Y

Further objects and advantages of this in-` vention will appear in the following description, and the novel features thereof will be particularlypointed out in the appended claims.'

In the drawings, Figure 1 is a perspective view of a churn-power constructed in accord-v ance with my invention. Fig. 2 is a longitudinal sectional view of the same with the frame folded. Fig. 3 is a transverse sectional view of the bearing'for the dasher staffs or spindles. Fig. 4 is a detail vertical section ofthe dashers and the contiguous portions of the dasher stads or spindles. Fig. 5 is a plan view of one of the dash'ers, partly in section.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings. l

The frame of the churn-power embodying my invention consists of 'a base having side bars l and cross-bars 2 and 3, a standard 4,` lhingedly connected for swinging movementV to the cross-bar 3 ofthe base, a swinging brace-frame 5, having side bars pivotall'y and said standard preferably consists of al guide-pin 1l, carried by the cross-bar and extending through a slot 12 in the standard, said pin being engaged by a thumb-nut 13, by which the standard and brace-frame may be clamped to prevent independent movement when the parts are in operative position. I also preferably provide detachable brace-rods 14, having a swiveled connection at 15 with the side bars at the base and provided with hooked upper extremities to engage eyes-19 on the side bars of the braceframe. It is obvious that by loosening the clamping device, consisting of the thumb-nut,

'which is threaded upon the guide-pin above described, and disengaging the brace-rods from the side bars ofthe brace-frame, the standard and brace-frame may be folded into the plane of the base, the side bars of the brace-frame lying between the side bars of vthe base and having their swinging movement limited by the cross-bar 3 of the base, and in this position the standard and braceframe may be secured by means of fasteninghooks 20 on the side bars of the base, which engage eyes 21 on the brace-frame. The cross-bar of the brace-frame is located at such av distance from the pivotal points of the side bars of said frame as to fall beyond the ends of the side bars of the base when the parts arefolded, las will be seen by referring to Fig. 2. Upon the upper arms 7 of the standard are arranged alined bearings 22, in which is mounted a driving-shaft 23, provided at one end with a fly-wheel'and pulley 24, which receives motion', through a belt 25, from a driving-wheel 26, which is mounted-upon a stubshaft 27, carried by the standard, said drivingwheel being provided with a suitable handle or crank 28.'

In order" to employ oppositely-revoluble dashers, I provide concentric dasher staffs or spindles 29 and 30, provided at their upper ends with oppositely-disposed 'bevel-pinions 291L and 30a to mesh with a pinion 31 on the driving-shaft, the upper end of the inner dasherl staff or spindle'29 being mounted above the plane of its pinion in a bearing formed in an extension or arm 32'of the contiguous front bearing 22. Said concentric staffs or spindles are also mounted in a bearing 33 on the face of the frame, said bearing being of sectional construction and having a IOO fixed member 33 and a movable member 33, which is preferably hinged to the fixed member and is adapted to be secured in its normal position by means of a catch 3l. In the construction illustrated this catch. consists of a thumb-screw threaded in the fixed member and having an elongated head which is adapted to pass through a slot 35 in the movable member. The turning of the thu mb-screw to arrange its head transversely with relation to the slot in the movable member locks said member in place. The exterior or tubular dashcr staff or spindle is held from downward displacement by the contact of the hub of its pinion 30" with the upper end of said sectional bearing, and the inner spindle is similarly held from downward displacement by the bearing of its pinion 29 upon the pinion 3l, which is carried by the driving-shaft.

The dashers which I prefer to employ in connection with the improved churn mechanism are of simple construction, each embodying simply a body portion or collar 3G and a plurality of looped blades or wings 37, provided with terminal studs 3S, which are threaded into suitable sockets in the edges of the collar. The lower dashcr, which is carried by the inner staff or spindle, has its collar fitted upon said spindle and secured by means of a set-screw 39, whereby it may be readily removed to facilitate cleansing, and the upper dashcr, which is carried bythe tubular staff or spindle, is secured thereto by means of spring-arms Ll-O, carried by said tubular staff or spindle and provided with inturned lower extremities, forming studs L.ll to engage sockets in the opposite side edges of the collar forming the body portion of the dasher. The tendency of the spring-arms is to swing outwardly and thus disengage their terminal studs from the sockets ofthe dashereollar, and in order to maintain them in operative engagement with the collar I employ a slide-ring 42. In other respects the upper dasher is identical in construction with the lower dasher.

The preferred form of dashcr-blade embodies a loop consisting of a single continuous elongated ring, the elongation or major axis being radial with relation to the axis of rotation of the dashcr, said ring having a single integral extension forming a one-ply stem, preferably threaded in a radial socket in the body portion or collar of the dasher,whereby in engaging or disengaging the blade the looped portion thereof serves as a handhold for turning the stem.

From the above description it will be seen that the framework, while adapted to fold to occupy the minimum space when not in use, is simple and strong, and when arranged in operative position it is adapted to be firmly secured against vibration by the holding devices provided for that purpose and ineluding the thumb-nut, by which the brace-frame and standard are locked at the desired relative adjustment, and the brace-rods, which struction of the dashers is such as to enable them to be readily cleansed, and thereby kept in a perfectly clean and hygienic condition. lt will be seen that the dasher-heads may be detached from their staffs or spindles, whereby they may be placed in a vessel and subjected to a boiling operation. The use of the spring-arms for connecting the upper dashcr with its staff or spindle obviates the objectionable features of a tubular staff, the tubular portion of said staff being arranged wholly outside of the churn-receptacle.

It is obvious, furthermore, that the churn mechanism constructed as above described may be used in connection with any churnreceptacle, for the reason that its operation is wholly independent of such receptacle, the dashers having no bearing upon any part thereof.

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

Having described my invention, what I claim is* l. A churn-power having a frame consisting of a base including parallel side bars, a standard hingedlyeonneeted to the base ata point between the side bars of the base and adapted to fold therebetween, a brace-frame pivotally mounted upon the side bars of the base to fold therebetween, and having a sliding connection with the standard, said braceframe being mounted eccentricallywith relation to the hinge of the standard, and means for clamping the standard and brace-frame together, to secure them in their desired relative positions, substantially as specified.
