T 0 all whom it may concern:
Be it known that I, JOHN M, Rononn, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Power- Operated churns, of which the following is a fu l, clear, concise, and exact description, refer ence being had to the accompanying drawings, forming a part of this specification.
My invention relates to churns and more especially to power driven operated churns which are adapted to be used in the home, at the dairies or in creameries. My invention is applicable to agitating devices in gen eral and the mechanically operated portions of my machine may be used in other relations than that here shown.
It is an object of my invention to provide a device of the character described which is adapted tov be manufactured in various sizes so that it may be installed at any desired place without the expenditure of a great sum of money.
Another object of my invention is to provide a churn of the dash type, and suitable power operated mechanism to effect vertical reciprocatory motions of the dash. hen the power operated mechanism is arranged in a slightly different position as shown in Fig. 4 it is adapted to be used with a churn or other agitating device having an agitating member which rotates in a horizontal plane.
Devices of the kind above referred to are usually operated by unskilled persons and are very often operated by women and children. It is, therefore, very desirable that all gearing and other machine parts be completely enclosed so that there will be no danger of the operator getting his or her fingers caught in the gearing. It is, therefore a further object of my invention to design a small and compact gearing which is readily adapted to be enclosed in a small casing wherein all moving parts of the device are encased. When enclosed the gear ing will be kept free from all dirt or other foreign substances which might contaminate the material worked upon.
It is a further object of the invention to provide an electrically operated churn or agitating device of the character set forth wherein all parts are arranged in compact relation and are assembled as a single unit Specification of Letters Patent.

which may be readily moved around and placed in a desired location.
Other objects of the invention will be apparent from the following detailed description of the device disclosed in the drawings accompanying this specification. In this specification and in the accompanying drawings I have disclosed one form which my invention may take which form is the best known to me at the present time. However, it is to be understood that by this specification and the accompanying drawings I do not intend to limit myself to the specific construction disclosed, as modifications of the specific construction may be required in the manufacture thereof or may occur to those skilled in this art. The real nature and scope of the invention disclosed is to be determined from the claims appended to this specification.
In the drawings I have disclosed two forms which my invention may take. The same reference numerals have been used to indicate the same parts throughout the sev oral views of the drawings in which- Fig. 1 is a vertical view partly in section of my complete device;
Fig. 2 is a horizontal section taken on line 22 of Fig. 1;
Fig. 3 is a top plan view with the casing shown in section in order to disclose the arrangement of the gearing within the casing;
Fig. 4 is a vertical view partly in section showing a slight modification of my improved. device. Fig. 4k is taken approxi- V. lately on line a a. of Fig. 5, and
Fig. 5 is a horizontal section taken approximately on line 55 of Fig. 4.
My device comprises a base member 1 which is preferably formed of planking, although it may be formed of metal, stone, or concrete, if so desired. The base member supports three standards 2 which are adapted to support, in the, manner shown, the driving mechanism of my device. These standards are secured to the base member in any desired manner. If the base member is of wood as is usual the standards will be secured thereto by means of bolts or screws.
Suitably located on the base member 1 are a plurality of pins 3, three being shown in the present instance. These pins are-adapted to position the container 4 of my agitating device, on the base member 1. In the preferred embodiment of my invention the container t is an earthenware vessel which is provided with a suitable cover member 5 provided with a central opening 6 as shown in Fig. 1. Through the opening 6 is adapted to pass the stem 7 which has secured to its lower end a dash member 8 constructed as shown more clearly in Fig. 2 of the drawings. Each of the blades of the dash member 8 is provided with an opening 9, which openings are adapted to assist in agitating the material in the container as the dash member is reciprocated vertically by means of the mechanism later to be described.
The upper end of the stem 7 is formed with an opening adapted to receive the lower end of a rack member 10 and a suitable clamping screw 11 is used to secure the stem 7 and rack 10 in rigid relation.
The three standards support a T-shaped base plate 12 which is adapted to support the motor and the gearing driven thereby.
The extending arms 13 of the base plate 12 are seeuredto the upper ends of the side standards 2 in the manner shown in Fig. 3. The motor 14 is of ordinary construction and may be adapted for use with direct or alternatingeurrent as the conditions of the case require. Suitable conducting wires 15 lead to a source of electrical supply which may be an ordinary lamp socket or any other electric plug. The motor is secured to the base plate 1 in any suitable manner. In Fig. 3 I have shown it secured thereto by means of screw headed bolts which engage threaded openings in the base plate 12. This base plate is usually made of iron, but may be constructed of wood or any other suitable material. Adjacent the motor and positioned on the base plate 12 I provide a c: sing 16. which casing is adapted to completely enclosethe moving parts of my device. This casing may be made of any desirable material and in any manner desired. It may even be formed integral with the base plate 12 providing one side is made removable in order to gain access to the gearing mechanism contained therein. As shown in the drawings, this casing comprises suitable side walls which are enclosed along their top edges by means of a cover plate 17 and along their front edge by means of a side plate 18. The cover plate 17 and side plate 18 are made removable and are secured to the side walls of the casing by means of set screws as shown. Projecting upwardly from the cover plate 17 is a hollow tube or extension 19 which-is adapted to provide the necessary verticalspace forthe rack 10 during its vertica lzreciproc'ation. If the casing is cast as a single unit the tube 19 will be formed integral-with the remaining portions of the easmg. 1 v
The shaft 20 of the motor is extended as shown-in Fig. 1 and secured to the shaft 20 is aworm 21'.- This-worm is adapted to en gage a worm wheel 22 which is mounted on a suitable shaft supported by the side walls of the casing 16.; The worm wheel carries a bearing pin 23 to which is connected one end of a link 'The other end of the link engages a bearing pin 25 rigidly, secured to a sector gear 26. The diameter of-the sector gear is greater than the diameter of the worm wheel With this construction it will be apparent that when the worm wheel 22 is rotated by means of the motor 1 1 back and forth movements will be imparted to the sect-or gear 26. The sector gear is supported on a suitable axis 27 carried by the side walls of the casing. Located forwardly of the shaft 2'? is a second shaft 28 which is likewise carried by the side walls of the casing. This shaf t supports a double pinion which is more clearly disclosed in Fig. 3 of the drawings. This double pinion includes a smaller pinion 29 which meshes directly'with the section gear 26 and is rotated through an angle of about 540 during the movement of the sector gear 26. The double pinion includes a larger pinion 30 which is adapted to mesh with the teeth on rack 10. The pinions 29 and are" formedintegral with or are rigidly secured to the hub 81 so that any motion imparted to pinion 29 will be immediately transmitted to pinion 30. Inasmuch as the pinion 30 is of larger diameter it will (a use an appreciable up and down movement of the rack 10 and the dash member 8 during the back and forth movements of the sector gear 26. The smooth side of the rack 10 bears against the side plate 18' and is guided in its vertical movements by any suitable guiding means which may be secured to the plate 18 or may project from the side walls of the casing 16.
From what has been described above it will be apparent that when the motor is running worm wheel, 22 will be rotated. This rotation etlccts back and forth movements of the serter gear 26 and the pinions 29 and 10 with the consequent reciprocations of the rack 10 and the dash member 8. This will result in the agitating of the material within the container at. If cream is placed within the container butter will be churned in the usual manner.
I will now describe theslight modifications of my device which are disclosed in Figs. at and 5 of the drawings. In these Figures the base member .1, the standards 2, the container. 4: and its cover member 5 remain the same as in the first modification described. The base plate is slightly modified in that it is provided with a suitable bearing 36 in which is mounted a vertical shaft 87 This shaft extends beneaththe base plate 35 and its lower end is provided with a socket member 38 and a clamping screw 39. :The socket member is adapted to receive tlie'squared'upper end of the shaft 40 which has secured to its lower end the agitating member 41.
The agitating member comprises four paddles, two of which, designated 42 in the drawings, are inclined in one direction and the other two of which, designated 43 in the drawings, are inclined in the other direction. lVith this construction it will be apparent that as the agitating member 41 is rotated back and forth in a horizontal plane the paddles will cause rapid agitation of the contents of the container. The upper end of the shaft 37 turns in a bearing 44 in the upper wall of the enclosing casing 45. This casing may be formed in any desirable manner as set forth above and is provided with a removable side wall 46 through which access may be had to the gearing contained in the casing. The motor is provided as in the first modification described with a worm 21 which engages worm wheel 47. This worm wheel carries a bearing pin 48 to which is connected one end of link 49. The other end of link 49 is connected to a bearing pin 5 rigidly secured to sector gear 51. This sector gear meshes directly with pinion 52 which is keyed to shaft 37. lVith this construction it will be apparent that as the motor rotates sector gear 51 will be moved back and forth as in the previously described modification and this back and forth movement of the sector gear 51 will cause back and forth rotation of the agitating member 41.
It will be apparent from the above description that in both modifications of my device I use a motor, a worm secured to the shaft of the motor, a worm wheel, a connecting link, a sector gear and a driving pinion which is adapted to drive the agitating device. The parts operate in the same manner and the only difference is that the parts are placed in a horizontal position in the second modification.
From the above description taken with the accompanying drawings the construction and operation of my device will be clear to those skilled in this art.
hat I claim as new and desire to secure by United States Letters Patent is:
extending upwardly from said base member, a base plate supported by said standards, a motor secured to said base plate, a worm driven by said motor, a worm wheel meshing with said worm, a sector gear, a link connecting said worm wheel to said sector gear, a double pinion having two pinions of different diameters, the pinion of smaller diameter meshing with said sector gear, an operated member, and a rack carried by said operated member and meshing with the larger pinion of said double pinion.
2. An agitating device of the character described comprising a base member, standards supported thereby, a base plate removably secured on said standards, a motor positioned on said base plate, an enclosed casing supported by said base plate, said casing having a removable cover plate whereby access may be obtained to said gearing, an operated member and a train of gearing entirely within said casing for connecting the motor to said operated member.
3. A power operated churn of the char acter described comprising a reciprocating driven member, a casing for slidably supporting said member, a motor, a train of gearing within said casing for operatively connecting the motor to said member, a removable base plate for said casing permitting removal of said operated member and a removable cover plateifor said casing permitting access to said gearing.
4. device of the character described comprising an operated member, a driving member and a train of gearing connecting the driving member to the operated member so that rotation of said driving member will cause straight line reciprocation of said operated member, said train of gearing comprising a worm on the shaft of said driving member, a worm wheel driven by said worm, a sector gear having a radius longer than the radius of the worm wheel, a link connecting the worm wheel to the sector gear and a double pinion connecting the sector gear to said operated member.
In witness whereof I hereunto subscribe my name this 23rd day of September, A. D., 1919.
