SPECIFICATION forming part of Letters Patent No. 408,126, dated July 30, 1889,
Application filed July 5, 1888. Serial No. 279,140. (No modell) To aZZ whom it may concern.-
Be it known that I, BETTIE MITcHUi/i, a citizen of the United States,residing at Hammons ville, in the county of Hart and State of Kentucky, have invented certain new and useful Improvements in Churns and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this speciiication.
This invention has relation te churns; and it has for its object the construction of a device of that charact-er which will be capable of accomplishing its purpose in the shortest possible space of time and with the least expense of physical force, and also in which the entrance into the churn-body of any insects, dust, or dirt, and of the escape from said churn-body of its contents in churning, will be prevented.
The invent-ion consists in certain novel fea tures in the construction, arrangement, and combination of parts,substantially as will be hereinafter fully described, and particularly pointed out in' the subjoined claims.
In the accompanying drawings,illustrating my invention, and in which the same parts of the several views are designated by the same letters of reference, Figure l is a vertical section of my invention, showing the relative position of the parts thereof; and Fig. 2 is a side elevatiomand shows the same located in position on the top of the churn-body.
A designates the upper portion of a churnbody, and B the cover for the same, which latter is formed with the usual perforation to permit the dasher-rod C to enter the churnbody. The churn-body, cover, and dasher-rod may each be of the usual and well-known construction, and may be made of any suitable size, form, and material.
Mounted on the top of the churn is a spring F, the uppermost extremity of which is provided with a ring or collar f, of sufficient diameter to receive the dasher-rod C, which latter is formed with a iiange or extension f', adapting it to rest upon the spring F and holding it against vertical displacement. The
spring Fis shown in the drawings as formed of spirally-coiled wire, butit will be quite oby vious that, although such is the preferred form, I do not wish to be understood as limiting myself to it, but reserve the liberty of making the spring of equal diameter throughout its length without departing from the spirit of the invention. This spring F, by reason of its resiliency, serves toautomatically return the dashern'od, and consequently the dasher, to its uppermost or normal position, and it thus, by obviating the necessity for any upward motion on the part of the operator, lessens the manual labor which would otherwise be required, and also renders said operation much more uniform, thereby increasing the supply of butter, and at the same time decreasing the time otherwise required in the production thereof.
Heretofore it was found in the operation of churning that the content-s of the churn was liable to splash out of and beyond the churn, and thus result lin a loss of that quantity of butter. Another disadvantage experienced was in the liability of the entrance into the churn of dust, dirt, insects, the.
In order to obviate these disadvantages, I inclose the spring F in a sack or cover G,which maybe made of leather, water-proof cloth, or paper, or any other suitable material. This sack or cover G is preferably made with a series of folds g, having the angular projections g between each pair thereof, as shown in the drawings. Tithin these angular projections g the coils of the spring F are located. The sack or cover G is provided at its upper extremity with a ring or collar H, which has frictional contact with the ring or collar f of the spring F, and serves to secure said sack or cover and the spring together at their upper extremities. The lower end of this sack or cover is confined between rings or disks D and J. These rings or disks are each formed with holes registering with each other and with the perforation in the churn cover, th ro ugh which the dasher-rod passes. They are respectively formed with depending springarms E and J', adaptedto engage each other and hold the rings or disks in proper position, as clearly shown in the drawings. This means of securing the disks together permits them to be removed and replaced simply by pulling the arms J outwardly and raising or low- ICO ering, as the ease maybe, disk J. The ring D is removable from the churn-cover in the same manner.
It will thus be seen that the sack or cover G can be readily and easily removed from and replaced around the spring F. It will further be seen thatby reason of the fact that the said sack or cover is connected at its upper end with the top of the spring F said sack and spring will move in unison.
Although I have shown the sack or cover G formed with a series of folds with angular projections between them to receive the coils of the spring, it will be quite obvious that, if desired, it may be made of some soft material loosely encircling said spring and still be capable of extension and depression to permit it to move in unison with the spring.
Having now described my invention, what I believe to be new, and desire to secure by Letters Patent, and what I therefore claim, is-
l. In a churn, the combination, with the top thereof and a flasher-rod having a flange or extension, of a spiral spring mounted on said churn-top and having a ring or collar at its upper extremity serving as a rest for said iiange, and a sack or cover having angulaiproj eetions to receive the coils of the spring' and having, also, a ring or collar at its top, for the purpose set forth.
2. In a ehurn,the co1nbination,with the top thereof and a dasher-rod,of a ring or disk D, having depending spring-arms E, and a ring or disk J likewise having springarms J all substantially as and for the purposes herein Set forth.
3. In a churn, the top thereof, a spiral spring mounted on said churn-top, and a flasher-rod, in combination with rings or disks D and J, having depending spring-arms E and J', respectively, and a sack or cover encircling the spiral spring formed to move in unison therewith and having its upper end secured to the flasher-rod and its lower end located between the rings or disks D and J.
4. The combination., with a churn-top, of a spring mounted thereon, a dasher-rod having a iiange adapting it te rest on said spring, and a sack or cover encircling said spring and having its upper extremity secured to said spring, whereby the latter and said cover will move in unison.
In testimony whereof I affix my signature in presence of two witnesses.
