' Application filed June29,19 03. Serial No. 163,661. (No model.) I
To all whom it may concern."
Be it known that we, CHARLES F. LANCASTER and JAMES D. ANDREWS, citizens of the'United States, residing at Petoskey, in the county of Emmet and State of Michigan, have invented fication.
This invention provides a peculiar form of Vent for revolving churns, having for its essential object to so dispose the vent as to prevent the formation of gas within the churn .due to the constant agitation of the fluid' which is received therein. It iswell known that in this construction of churn the revolution of thebody after the cream is placed therein causes the formation of no small amount of gas, which when the churn is opened preparatory to removing the contents after operation of the Same forces out the liquid contents of the receptacle under great pressure, and this is the cause of great inconvenience at times, as will be readily apparent to those cognizant with this art.
For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.
away, showing more particularly the peculiar,
construction of the vent. Fig. 3 is a detail perspective view of the vent-tube and the securing-collar cooperating therewith.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The invention is adapted for application to any ordinary structure of revolving churn,-
that illustrated in the drawings'consisting of the churn-body l, mounted for revolution upon suitable supports 2, which are projected from a base 3. The churn is operated by a crank 4, disposed upon one of the journals 5 and provided with a crank-handle 6'. It will be understood that any suitable construction may be utilized within the contemplation of our invention as regards the structure of the parts hereinbefore described.
The vital feature of the invention, as before premised, lies in the peculiar form of vent utilized. The vent consists of a tube 7, which is disposed upon the-hollow journal 8 of the.
churn-body 1, extending through the said journal in a manner readily seen. The tube 7 is providedwith the inner curved end 'portion 7 the special advantage of which is to prevent escape of the contents of the churnbody through the vent-tube, at the same time permitting, however, escape of any gas which may be formed during the agitation of the conthe element 9 as far as utility of the same is concerned, since the latter would answer the purpose as well as the collar illustrated. In'
order to hold the vent-tube in position and to maintain the curved end portion 7 thereof in its relative position with the open end of the tube downward, a set-collar lO'is removably disposed upon the outer end portion of the tube. The set-collar 10 maybe held in the position shown by any suitable means, such as a setscrew or the like. In the drawings a weight 11 depends from the vent-tube, which weight normally holds the curved end portion 7 thereof in its proper position, and this weight 11 is connected to the set-collar 10 by means of a rod 12,.whicl1 rod may be permanently formed withthe weight. upon its upper end, and this threaded end The rod is threaded portion of the same is adapted to be screwed into an opening in the set-collar 10 and into contact with the vent-tube 7 to secure the seteollar 10 to the vent-tube, as wellas to support the weight upon the set-collar. It will thus be seen that during the revolution of the churn-body l, which is actuated by the crankhandle or other equivalent device, the venttube is normally held in position with the curved end portion thereof in an uppermost position. During the revolution of the churn the gas which is formed by the agitation of the contents of the receptacle is allowed to escape through the vent-tube, thus preventing the resulting inconvenience described above.
The device embodies a high degree of simplicity, and consequent cheapness relative to the cost of construction, this being quite an essential advantage thereof. The device is also susceptible of a broad application in that it may be disposed upon churn-bodies with but a slight modification, if any, relative to the construction thereof.
Having thus described the invention, what is claimed as new is In a churn, the combination with a body, a hollow journal disposed upon the said body and having a portion passed through an opening in the body, an annular flange disposed upon the journal and adapted to abut against the outer side of the body ad jaeent the opening aforesaid, securing means passed through the flange to secure the journal to the body, a vent-tube passing through the said hollow journal having its inner end curved within the churn-body and its outer end projected beyond the journal, a stop-collar disposed upon the inner portion of the vent-tube to limit the outward movement thereof, a setcollar mounted upon the outer end of the venttube to limit the inward movement thereof and provided with a threaded opening, a rod having a threaded end to be screwed in the threaded opening of the set-collar to secure the same to the vent-tube, and a weight disposed'upon the rod and adapted to hold the curved inner end of the 'e1it-tube at an ascertained position.
In testimony whereof we aiiix our signatures in presence of two witnesses.
