CHURN.

SPECIFICATION forming part of Letters Patent No. 502,179, dated July 25, 1893.

application filed April 11 1893.

To all whom it may concern.-

Be it known that I, WORDEN EDMISTER, a citizen of the United States, residing at Mount Vernon, in the county of Knox and State of Ohio, have invented certain new and useful Improvements in Ventilators for Ghurns; and I do declare the following to be a full, clear, and exact description of theinveution, 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 of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in churns, and it has for its object among others to provide an improved churn with asimple and cheap selfoperating or automatic ventilating device whereby the gas may be automatically allowed to escape from the interior of the churn.

. I provide simple mechanism for accomplishing this purpose, still it is positive in its action and not liable to get out of order. The mechanism except I the cock or valve is arranged outside the churn where it will not be afiected by the cream and where it can be readily repaired or replaced by new if necessary. I further provide means for preventing the soiling of the floor by what little froth there may escape through the tube when the valve is open to allow of the escape of the contained gas.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention in this instance resides in the peculiar combinations, and the construction, arrangement and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the lettors of reference marked thereon, form a part of this specification, and in which Figure 1 is a side elevation of a churn provided with my improvements. Fig. 2 is a section through the ventilating mechanism and drip bowl. Fig. 3 is an end view of the churn.

Like letters of reference indicate like parts in all the views where they appear.

Referring now to the details of the drawings by letter, A designates the churn body or cream receptacle which may be of any of the well known forms of revolving churns, either square, round or any other desired shape and mounted to be revolved in any suitable manner on the axis or pintles B sup ported in suitable hearings in suitable supports as A. It should of course be provided with a suitable cover, and in one end is formed a hole in which is fitted a tube D the inner end of which extends within the churn body as shown, and which is adapted to be closed by a plug 01' valve E which is fitted to the inner end of the tube so as to form a tight joint and prevent leakage when the churn is being revolved. Suitable packing may be employed if necessary. This valve or plug is normally held so as to close the end of the tube by the lever E which is pivoted at one end as at e to any suitable device as a lug d on the outer face of the end of the churn through which thetube passes, and this lever has pivotally connected therewith between its ends one end of the rod F the other end of which is connected with the plug or valve E as shown, and the end of the lever opposite that which is pivoted is acted upon byaspring G which is confined between the said end and the end of the churn body so as to press the said end of the lever outward and thus draw on the rod F and keep the valve or plug against or within the end of the tube.

H is a rub block or an abutment arranged in such a position as to be engaged by the free end of the lever at each revolution of the churn, and this block has a beveled portion hover which the end of the lever rubs as the churn is revolved as will be readily understood from Fig. 1, the block being so located with relation to the lever that it acts to operate the lever so as to open the valve when the outlet reaches the uppermost position whereby the valve will be opened when the gas is at the top of the churn and there is the least liability of the cream running out with the gas and air.

The operation will be readily understood from the foregoing description when taken in connection with the annexed drawings. Each time the churn revolves the free end of the lever will ride upon the rub block and as it rides upon the bevel or tapered portion thereof the spring is compressed and the rod connected with the said lever and with the valve is forced inward thus throwing the valve from its seat and admitting of the escape of the air and gas from within the churn. As the churn further revolves the free end of the lever leaves the rub block and the spring returns the parts to their normal position and the valve closes the inner end of the tube.

In order to catch what cream and froth es capes with the gas and prevent its spilling onto the floor I have provided a means for catching the same as it issues from the tube. It consists of a bowl I having a hole fitted over the outer end of the tube so that any cream or froth that comes out of the tube will flow into the bowl.

J is a dish shaped piece secured to the rod F to move therewith and fitted within the bowl, which at its outer face has an opening it as shown. WVhen the frothy substance enters the tube it is carried out of the same with the gas and air and striking against the inner or concave side of the dish-shaped piece will run down the same and into the bowl. It may be removed therefrom in any suitable manner, as for instance, by a suitable cock as shown at K.

The advantages of the construction above described will be readily appreciated by those familiar with this class of devices, and the cost thereof being small will bring the same within the means of any one.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What I claim as new is l. The combination with a revolving churn, of a valve for closing a vent-opening in the end thereof and provided with a stem, a lever pivoted on the churn to normally hold said valve in its closed position, a stationary rubblock having a beveled portion to engage said lever to open the valve and a bowl arranged over the outer end of the vent opening and through which the valve-stem passes, substantially as described.

2. The combination with a revolving churn, of a valve for closing a vent-opening in the end thereof and provided with a stem, a lever pivoted on the churn to normally hold said valve in a closed position, a stationary rubblock having a beveled portion to engage said lever to open the valve, a bowl arranged over the outer end of the vent opening and through which the valve stem passes, and provided with a discharge pipe with cock, substantially as described.

3. The combination with a revolving churn, of a valve for closing a vent opening in the end thereof and provided with a stem, a lever pivoted on the churn to normally hold said valve in a closed position, a stationary rubblock having a beveled portion to engage said lever to open the valve, a bowl arranged over the outer end of the vent opening and through which the valve-stem passes and provided with a discharge pipe with cock, and a dish shaped piece carried by the valve-stem to close an opening in the bowl, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WORDEN EDMISTER.
