SPECIFICATION forming part of Letters Patent No. 427,457, dated May 6, 1890.
Application filed February 6, 1890. Serial No. 339,392. (No model.)
T0 all whom it may concern.-
Be it known that I, HARVEY BROKAW, a citizen of the United States of America, residing at \Vapakon eta, in the county of Auglaize and State of Ohio, have invented certain new and useful Improvements in Churn-Closures; and I do herebydeelare 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 letters of reference marked thereon, which form a part of this specification.
My invention relates to closures for churns; and it consists in the improved construction hereinafter described and set forth, whereby a simple an d efficient closure is provided that may readily and conveniently be locked and unlocked, the several metal parts being so disposed that they are of simple form and can be severally produced in the form of inexpensive castings.
In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of a churn-closure and its devices in a locked position and constructed in accordance with my improvements, and Fig. 2 is a vertical sectional View.
Internally and near the edge of the bodyA is a metal ring B, upon the upper side of which vertical lugs 04 are cast, said lugs having a horizontally-extending head I), the adjacent faces of therunder side and adjacent edge of the lug being plane-faced to forman abrupt portion. ring B is turned to form a shoulder c, as shown in Fig. 2.
A circular disk C, of wood, has attached thereto an annular ring D, the horizontal portion of which is provided with ears (Z, through which screws pass to attach it to the wooden disk, an annular gasket 6, of cork, being clamped between the disk and ring, so that its under channel will receive the shoulder a to present an air-tight bearing thereat. On
the upper side of the ring at equidistant points are projections cl, each of which has a radial channel increasing in depth toward the outside. A vertical loop 6 spans the channel of each projection.
The inner edge of the metal An arched bar or casting E has its lower ends bent horizontally and perforated for the passage of screws to secure said bar centrally to the wooden disk, and the central part of said bar is enlarged and perforated to form a bearing f, the perforation in which is internally threaded for the passage of a screwthreaded spindle F, the upper end of which carries a handle g, while the lower end is connected to but turns in the casting G, having four lateral ears h, each of which is bifurcated and carries a pin 1', with which engages the inner hooked end j of one of a series of four radial arms, the inner end of each arm adjacent to its hookbeing provided with a shoulder 7t, located adjacent to the outer ends of the ears to brace the connections relative to each other and prevent unnecessary vibration of the parts, and also enable the ears to bear directly upon and operate the arms when said casting has arrived at its lowest point of descent. The outer portions of the arms are seated in the channels of the projections of the ring and play through the loops of the same.
In practice the closure with its parts is placed in position on the ring A so that the inner shoulder of the latter will enter and bear in the recess of the gasket. The casting G is meanwhile at its highest point of movement, and hence the arms are so inclined that their outer ends are at their lower point. The closure can be rotated to a limited extent to bring the outer ends of the arms in contact with the lug a beneath the heads of the same. The threaded spindle can then be revolved, so as to effect the descent of the casting G, which in turn depresses the inner ends of the arms, and, inasmuch as the upper ends of the channels in the projections d serve as fulcrums for said arms, the outer ends of said arms will be elevated, so as to bind against the under faces of the heads of said projections. The slight movement of the spindle in a reverse direction will release the parts sufficiently to admit of the reverse movement of the closure and the disengagement of its arms. It will therefore be seen that the several parts constituting my improvement are but few and simple and that they may be readily produced in the form of castings. 3y ein i loying the central frame G I not only avoid a multiplicity of connections and parts to secure the same end, but reduce the number of sections heretofore necessary to secure similar results and positively etfect the movement of the arms.
I am aware that prior to my invention it has been proposed in a construction somewhat similar to have a vertical threaded spindle attached to the top of the disk and a nut and casting playing upon the same, the casting havin arms pivotally connected thereto at their inner ends. I am also aware of a proposed prior construction wherein the disk carries a threaded socket at its upper side, in which a threaded spindle plays vertically, a castin being supported on said spindle and adapted to be locked and depressed by a camlcver. My invention will be principally distinguished from such constructions in that the screw travels in the arched bar and permanently carries a casting G at its lower end, the arrangement bein such that the said cast-in G and its arms are positively operated, and the arched bar will relieve the top and. other parts from considerable of the strain.
I claim- 1. The combination, in a closure for churns, of the bodyhavin hooked lugs a, a disk provided with an arched bar, a threaded spindle seated therein and carrying a frame at its lower end, and arms pivotally connected to said frame, fulcrumed on the disk, as de scribed, and adapted to have their outer ends elevated to engage the lugs when the frame is depressed, substantially as set forth.
2. The combination, in a closure for churns, of the body having hooked lugs (I, a circular disk having projections (1, provided with outwardly-inclined channels, an arched bar secured on said disk, a threaded spindle hearing therein and carrying a frame at its lower end, and arms pivotally secured to said frame, fulcrumcd on the disk, as described, and bearing in said channels, and adapted to have their outer ends elevated to engage the lugs when said frame is depressed, substantially as set forth.
3. The con'ibination, in a ehurn-body and closure therefor, of a ringA,internally seated in the body, as described, and ljiaving hooked lugs a, a disk provided with an arched bar, a threaded spindle bearing therein and carrying a frame at its lower end, and arms pivotally connected to said frame and engaging fulcrums on the covendisk, and adapted to have their outer ends elevated to engage the lugs when the frame is depressed, substantially as set forth.
4. The combination, in a churn-body and closure therefor, of the hooked lugs a, a disk having an annular ring provided with projections (1, having channels inclining outwardly, and loops spanning the same, ail-arched bar seated on the said disk, having a threaded spindle carrying a frame at its lower end,and arms pivotally connected to said frame and bearing in said channels to engage said lugs, and adapted to have t-heirouter ends elevated to lock the parts when the frame is depressed, substantially as set forth.
5. The combination, in a-churn-body and closure therefor, of the hooked lugs (1,, a circular disk having an annular ring of larger dimension secured marginally thereto to confine a gasket, and having projections on its upper side provided with channels inclining outward, and an arched barseated on the said disk, having a spindle carrying a frame at its lower end, and arms pivotally connected to the frame and bearing in said channels to engage said lugs, substantially as set forth.
' (3. The combination, in a churn-body and closure therefor, of the hooked lugs (0,, carried by thebody,acovendisk havingchanneled projections d adjacent to its margin, an arched bar seated centrally on said disk, a threaded spindle bearing in said bar and frame carried by said spindle, and the arms pivotally connected to the frame and shouldered adjacent thereto and bearing in said channels to engage said lugs a, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
