CHARLES L. MERRILL, OF INDIANAPOLIS, INDIANA.
JOURNAL-BEARING AND DOG FOR CHAIN-PUMPS.
SPECIFIGATION forming part of Letters Patent No. 278,992, dated June Applio ation filed April 19, 1883. (No model.)
To all whom; it may concern.-
Be it known that I, O. L. MERRILL, of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and use ful Improvements in Journal Bearings and Dogs for Chain-Pumps; and I do hereby declare 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in journal-bearings and dogs for chain-pumps; and it consists in combining a. casting formed in two pieces,which combines a journal-bearing and pivotal ears, with a pawl that is adapted to be pivoted between the ears and engage with the ratchet-wheel used in chain-pumps for preventing rearward motion of the hoisting-buckets, as will 'be more fully described hereinafter.
In the accompanying drawings, Figure l is a side elevation of my invention complete, showing the ratchet-wheel in dotted lines. Fig. 2 is a top plan viewof my invention. Fig. 3 is a detail perspective, showing the parts detached. Fig. 4 is a top plan view of a modification.
A represents a casting, which forms the un-, der plate or base of my invention, which is provided at one end with the half of a journal-bearing, B, and at its rear end with the ear C and the ear D, which latter ear is cut off at the point intersecting the center of the bearing E for the pivoted pawl F, which is pivoted between it and the upper half of the bearing G, made in the rear end of the upper plate, H, the forward end of which has formed integrally with it the upper half of the journalhearing I. These plates have their portions of journal-bearings cast so as to register the one with the other, and form complete bearings when put together, as shown at Fig. 1, and are further provided with the holes K, registering with each other, through which screws are passed in order to secure the plates in position.
In Fig. 4 I have shown a modification in which the pawl has formed on one of its bearing ends the flanged head M, the under plate being provided with an ear, N,havingase1ni'- circular bearing, 0.
The object of my invention is to provide a bearing for the pawl which will always hold it in direct line with the ratchet-wheel, and thus prevent it from having a lateral play at its free en' d in such a manner as to allow its end to b come disengaged from the wheel, and thus allow the handle to fly back. Another object is that the pawl can be readily removed in case its free end should become injured or broken.
Having thus described my invention, I claim The journal-bearings composed of a baseof a journal-bearing formed integrally therewith, and an upper section made to register with the under section, and having the upper half of the journal-bearing and of the pawl.- bearing formed therewith, in combination with a pawl that is adapted to be pivoted between the two castings, the said castings being further provided with holes registering with each other, through which screws may be inserted for securing them in position on the pump curb, substantially as shown and described.
In testimony whereof I affixmy signature in presence of two witnesses.
. CHARLES LEE MERRILL.
