N. Perms. Vhowmhcgnphen warm! m c :EPECEFICATION forming part of Letters Patent No. 378,144, dated February 21, 1888.
Application filed December 16, 1887. Serial No. 255,015. (No model.)
To aZZ whom it may concern:
Be it known that I, SAMUEL D. PALMER, a citizen of the United States, residing in the city of Rockford, in the county of W'innebago and State of Illinois, have invented certain new and useful Improvements in Ohurns, of which the following is a specification.
The object of this invention is to produce a churndid fastening simple in construction, easy of application, and not liable to become uufastened when in use.
This invention consists of a ringhead with uprising ears, hails pivoted to the ears, a removable head with a cam-fastening to engage the free center portion of the bails to press the head to the ring-head, and in the various combinations of these parts.
In the accompanying drawings, Figure 1 is a plan view of a churn-head embodying my invention. Fig. 2 is a vertical central section of the same. Fig. 3 is a representation of the cam-fastening in isometrical perspective.
A ring-head, 1, has its outer edge fitted to enter the croze of the barrel forming the churn, and is provided with a central circular opening. A circular rib, 3, rises from the in ner edge of the ringhead. Ears 4 rise from its upper face and stud-journals 5, projecting laterally therefrom. The ends of the bails 6 are made in I form to receive the stud-journals 5 on the ears 1, which forms apivotal connection of the bails with the ears.
The removable head consists of an annular ring, 7, of angle-iron form in section, which receives the main portion 8 of the head. The under face of the head is recessed, and an annular packing-ring, 9, of cork or other suitable material, is placed within the recess. The annular ring 7 is provided with a transverse center brace, 10, from the center of which rises a tubular stud, 11. This stud has a shoulder, 12, for a purpose to appear hereinafter.
The double cam represented in Fig. 3 and alt-13, Figs. 1 and 2, is of circular dish form with a central tubular hub, 14, rising from its upper face. The periphery is divided into two equal flanged cams, 15, having their highest points opposite. The highest points of the cam-flanges are cut away to admit the bails to pass under the cams, and the lower end portions of the respective cam-flanges extend under the cut-away portion to receive the bail in position to be operated upon by the cam when rotated.
A hand-hold is formed by a transverse vertical web, 16, connecting the central hub, 13, with the outer edge, and by means of which the cam may be oscillated.
A double cam constructed as above described is so placed upon the removable head that the reduced portion of the stud 11 en ters the opening in the hub 14 and projects through sutliciently to permit the easy oscillatory movement of the double cam. The cam proper rests upon the shoulder 12 of the stud 11, upon which it oscillates.
Abolt, 17, is passed through the removable head and tubular stud 11. A thumb-nut, 18, is then turned down to firmly clamp the parts together, but leaving the cam free to oscillate.
\Vhen it is desired to fasten the lid in position, the bails are turned inward, and will rest upon the upper face of the cams. By then turning the cams the bails will descend through the cut-away portion, and will rest upon the lower portion of the cam, after which, by a continued movement of the cam in a direction to cause its cam-flanges to override the free portion of the bails, the bails will opcrate to clamp and hold the removable lid in position on the head. A reverse movement of the cam will release the bails and permit them to swing outward and the head to be removed from the churn.
I claim as my invention- 1. The combination, with a churn having bails pivoted thereto, of a removable head, and a cam secured to the said head to engage the free portions of the bails, substantially as set forth.
2. The combination, with a churn provided with a ring-head fixed thereto, the said ringhead having ears rising therefrom, of bails pivoted to the said cars, a removable head, 9
and a cam secured to the removable head to engage the free portion of the bails, substantially as set forth.
3. In a churn-head in combination with bails, an oscillating cam-fastening having independent inclines, the upper portion of the transverse vertical web, forming a hand-hold, lower end portions of said inclines forming substantially as set forth. rests to receive the bails, substantially as set forth SAMUEL D. PALMER. 5 4. In combination with a churn provided Witnesses:
With bails, an oscillating cam-fastening for the A. O. BEHEL,
bails, the said cam-fastening provided with a E. BEHEL.
