BARN CLEANER CHAIN Filed Sept. 8, 1955 INVENTOR WERNER E.JOHNSON I siz/lggfW gh ATTORNEYS United States Patent BARN CLEANER CHAIN Werner E. Johnson, Lena, Wis.
Application September 8, 1955, Serial No. 533,052
1 Claim. (Cl. 74-250) This invention appertains to chains and more particularly to conveyor chains of the type used in barn cleaners and driven from a sprocket wheel.
It has been proposed to form the links of the chain in such a manner that a link can be removed and replaced when worn or broken without dismantling the entire conveyor and in such chains, the danger of the links being accidentally disconnected is always present.
One of the primary objects of my invention is the provision of a chain link which can be easily and quickly connected with or disconnected from a like link, with means whereby when the links are connected accidental disconnection thereof is precluded irrespective of the position of the links relative to one another and whether or not the chain is loose or taut.
Another salient object of my invention is the provision of a chain link having a hook for receiving the body portion of an adjacent link and having a seat formed in the entrance throat thereof for detachably receiving a wedge pin, whereby when said pin is driven in place in the seat accidental movement of a link out of the throat is eliminated.
A further important object of my invention is to provide a chain link of the above character which will be durable and efficient in use, one that will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.
With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described and claimed, and illustrated in the accompanying drawing, in which drawing,
Figure 1 is a fragmentary side elevational view of a chain showing the use of my novel links, parts of the chain being shown in longitudinal section, with the section taken on the line 11 of Figure 2, looking in the direction of the arrows;
Figure 2 is a fragmentary top plan view of a chain constructed in accordance with my invention, and
Figure 3 is an enlarged fragmentary detail transverse sectional view, taken on the line 3-3 of Figure 1, looking in the direction of the arrows.
Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter C generally indicates a chain including a plurality of like links 5 constnlcted in accordance with the invention. Each link includes a substantially flat main body portion 6 having a longitudinally extending opening 7 therein for receiving the teeth of a sprocket wheel (not shown). Formed on one end of the body portion 6 is a book 8, which is adapted to be inserted through the opening 7 of an adjacent link for operatively connecting the links together to form a chain. The book 8 includes a rearwardly curved hill 9 terminating in spaced relation to the body portion 6 to define an entrance throat 10 for the body portion of an adjacent link. In accordance with my invention, the free end of the hill 9 is curved, as at 11, on an arc of a circle and the body portion 6 of the link adjacent to the bill 9 is provided with a like curved surface 12. The
From the foregoing description, it can be seen that I have provided an exceptionally simple form of chain link in which the entrance throat for an adjacent link is positively closed so as to prevent the accidental displacement of connected links.
Changes in details may be made without departing from the spirit or the scope of this invention, but what i claim as new is:
A power driven conveyor chain compn'sing a plurality of connected like links, each of said links including a body portion having a longitudinally extending opening and a hook on one end of the body portion for receiving the body portion of an adjacent link, said book including a curved bill extending back toward the body portion and terminating in spaced relation to said body portion defining an entrance throat into said hook, adjacent facing surfaces of said bill and body portion being provided with curved seats formed on the same are of a circle and having the same axis, and a wedge pin extending transversely of the body driven into said throat into frictional engagement with the seats for closing said throat, said pin being tapered toward its opposite ends, whereby the same can be driven into the throat from either side thereof.
