CHURN.

SPECIFICATION forming part of Letters Patent No. 561,131, dated June 2, 1896.

Application filed November 15 1894. Serial No. 528,858. (No model.)

To all whom t may concern.-

Be it known that I, JOSEPH F. RICHARDSON. a citizen of the'United States, residing at Birks City, in the county of Daviess and State of Kentucky, have invented a new and useful Churn, of which the following is a specification.

This invention relates to an improvement in that class of churns wherein a body portion or receptacle is mounted for rocking movement, whereby the cream to be churned will be dashed from one end of the body to the other at each operation thereof.

My invention resides in certain peculiar features of construction connected with the lid for closing an opening in the top of the body portion and in the means for mounting said lid and securing it in place. The obj ect contemplated is to provide a lid which may be readily and quickly removed, and which may be secured in place with all necessary efficiency to prevent the escape of cream from the body portion.

To this end the invention consists in forming in the top of the body portion a rectangular opening and in providing flanges projectin g inwardly in the plane of the top. Upon these flanges a rectangular frame is removably seated, said frame carrying a glass plate and being held in place at one edge by means of an additional flange extending inwardly from one side of the opening above and parallel with the plane of the top of the body. On the side opposite to this additional flange an inwardly-proj ecting lug is arranged,which lug is adapted to coact with a ring or link pivoted to the frame of the glass plate and capable of swinging under the lug to positively engage it and hold the frame of the glass plate in place. v

The invention further consists in a peculiar manner of forming the opening in the body portion, whereby the material removed to form the opening serves to form a series of flanges integral with the sheet metal composing the body portion. This is accomplished by first forming two intersecting slots extending diagonally across the proposed opening and by subsequently bending the free ends of 5o the triangular tongues formed by these slots back upon the main Yor body portions of the same to provide reinforcement, as more fully described hereinafter.

In' the drawings, Figure l is a perspective View of a churn embodying the essential features of my invention. Fig. 2 is avertical longitudinal section thereof. Fig. 3 is a plan view of the opening in the body portion, showingthe arrangement of the flanges thereof. Fig. 4 is a detail perspective of the lid of the body portion. Fig. 5 is a plan View illustrating the slots which are formed in the body portion in the process of forming the opening therein.

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

1 indicates a churn-body, preferably constructed of sheet metal and shaped as a parallelogram, it being elongated longitudinally and provided at its sides and at its lower portion with the anges 2,which project horizontally therefrom, and which are securely fastened to the board 3 of the parallel rockers 4, a brace 5 being providedvhereby the rigidity of the rockers is insured.

6 indicates a handle, which is rigidly secured to one of the rockers 4, and which projects upwardly therefrom, its purpose being to furnish means for imparting motion to the churn-body.

Located within the churn-body and projecting upwardly from the bottom thereof is a transverse rib 7, provided to break the cream as it is forced back and forth through the bodyand accelerate the churning operation. Formed in the upper side of the body l and at the middle thereof is an opening 8, apapproximately square in plan, which extends from one side of the body portion to the other, and rising vertically from the sides of the opening 8 is the flange 9, which extends continuously around the opening and is adapted to form a guard therefor.

10 indicates inwardly-extending horizontal tongues or flanges equal in number to the sides of the opening and approximately triangular in plan, the same being formed and separated by the diagonally-disposed intersecting slots a, (shown in Fig. 5,) the extremities of which are located at the four corners of the opening. After thus separating the IOO tongues the points thereof are folded or doubled back to forni thickened flanges or rolls adapted te support a lid l2 for the churnbody, said lid fitting within the upstanding flange 9. The tongues are preferably doubled to forni three folds, whereby the points are covered or rolled in between the remaining folds.

ll indicates an additional flange secured to the inside of the flange 9 at one end thereof and proj ecting inwardly and horizontally above the adjacent flange l and parallel therewith. The purpose of this flange is to confine one side of the lid or frame 12 in place. The lid or frame l2 is composed of metal suitably constructed and provided with a glass plate One side of the traine or lid l2 has secured thereto an eye 14, carrying the ring l5, and by these means the ring l5 is mounted to swing freely in a vertical plane. By reierence to Fig. 2 it will be seen that the lid or fralne l2 is seated within the flange 9 and that it rests upon the flanges l0. Rigidly secured to the flange fl and directly opposite the point carrying the flange 1l is an inwardly-projectinglug 16, under which the ring l5 is adapted to be forced, whereby the lid or traine .l2 'is forced down upon the flanges 10, which will effectively close the opening 8 and make the escape of air or crea-ni impossible. The rolling` of the triangular tongues to forni the flanges l0 produces a cushion havin g a yielding quality,\vliieh provides for forlnin g an airtight joint.

Formed in one end of the body portion 1 and at the lower side thereof is a dischargeopening 17, surrounded by a nozzle 18 and provided with a plug 1f). The purpose of this arrangement is to permit the withdrawal of.' the residue left by the churning operation, as is eolninon in all such apparatus.

Changes in the form, proportion, and the ininor details of construction may be resorted to without departing from the spirit or sacrificin g any of the advantages of this invention.

Having described iny invention7 what I claim isr A churn having a rockin g body con structed of sheet metal and provided in its upper side with an opening S surrounded by an upstanding flange 9, horizontal resilient or compressible supporting-flanges l() arranged wit-hin the flange f) and forming a cushion, the flangesI lf) being constructed of triangular tongues struck from the churn-bod y and folded or rolled outwardly or toward the flange J to forni said opening S, a lid fitted within the flange 9 and resting upon the flanges 10, and means for forcibly depressing the lid upon the flanges l0 to forni an air-tight joint, sub stantially as specified.

In testimony that I clainl the foregoing as my own I have hereto affixed ni y signature in the presence of two witnesses.
