PUMP-ROD COUPLING-PIN.
SPECIFICATION forming part of Letters Patent No. 775,200, dated November 15, 1904.
Application filed March 19, 1904. Serial No. 199,032. No model.)
To (11/ 117mm 1'2 may concern:
Be it known that I, FRANK Isaac \VEBBER, a citizen of the United States, residing at Oxford, in the county of Furnas and State of Nebraska. have invented a new and useful Pump- Rod Coupling-Pin, of which the following is a specification.
My invention relates to coupling-pins, being especially designed for use in connecting pump-rods to windmills, and has for its objects to produce a simple inexpensive device of this character which when inserted to position will automatically lock against accidental removal and one in which the pivotal axis of the key may be readily changed to accommodate the pin for use in either a horizontal or vertical position.
\Vith these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.
In the accompanying drawings, Figure 1 is a sectional elevation illustrating the pin applied in use. Fig. 2 is a perspective view of the pin. Figs. 3 and A are detail views illustrating the locking-key pivoted in ditferent positions. Fig. 5 is a detail transverse section.
Referring to the drawings, 1 designates a pump-rod, 2 the cross-head to which the same is coupled, and 3 my improved coupling pin or bolt by which said parts are connected, the parts I and 2, which are conventionally shown herein. being of the usual or any preferred construction.
The pin or bolt 3, which is of circular form in cross-section, is provided adjacent to its front rounded end with a central longitudinal 510m. and has formed at its rear end a shouldered head 5, in which is formed a substantially crescent-shape opening or slot 6 for the reception of an elongated metal link 7, attention being especially directed to the fact that the head 5 is flattened in rear of the shoulder in a plane coincident with the transverse axis of the slot 4 for a purpose which will hereinafter appear. Pivoted within the slotat by means of a pintle 8 is a locking member or key 9, formed, preferably, from galvanized l sheet-steel or other suitable non-corrosive metal. This key,which is cccentrically pivoted and adapted to swing freely upon its pivot by gravity, is slightly rounded at its ends and is perforated, as at 10, through its shorter end for the twofold purpose of rendering the longer end or portion of the key heavier, thus adapting it to swing more readily by gravity and for the reception of a supplemental locking member or pin 11, whereby the key may in someinstances be secured in its locking position.
Formed transversely through the bolt 3 and within the longitudinal scope of the slot i is a pair of perforations 12, either of which may receive the pintle 8, whereby the pivotal point of the key 9 may be shifted toward either end of the slot i to adapt the key for operation, according to the use of the bolt, in either a horizontal or a vertical position, it being ap parent that when the bolt is to be used in the latter position the pivoting-pin should be inserted through the perforation 12 nearest to the forward end of the slot, thereby bringing the longer arm of the key uppermost and adapting it to swing readily downward by gravity.
It is to be particularly noted that the walls of the slot 4: are oppositely beveled transversely of the bolt, as at 13, thus obviating liability of the key 9 becoming cramped or bound between said edges and further permitting the key to assume a slight transverse inclination in the slot, whereby its movement to locking position when the bolt is horizontal will be assisted.
In practice the link 7 will assume a position and be retained at one end or the other of a slot 6, and will thereby serve as a weight tending to rotate the bolt in a direction corresponding to the position of the link, whereby when the bolt is inserted to coupling position it will turn automatically sul'iiciently to initiate the swinging movement of the key 9, which of course will move automatically to a position transversely of the bolt and with the longer or weighted end of the key downward a similar automatic movement of the key following upon the insertion of the-bolt in avertical position, as heretofore explained.
From the foregoing it is apparent that I produce a simple inexpensive device admirably adapted for the attainment of the ends in view, it being understood that minor changes in the details herein set forth may be resorted to without departing from the spirit of the invention.
Having thus described the invention, what is claimed is- 1. The combination with a bolt provided with ahead and a longitudinal slot,of a locking member eccentrically pivoted in said slot and adapted to swing automatically in either direction to a position transversely of the bolt.
2. The combination with a bolt provided with a head and having a longitudinal slot, of a locking member eccentrically pivoted in said slot and adapted to swing automatically in either direction to a position transversely of the bolt, said bolt being provided with a pair of perforations, and a pivotal axle for the locking-key designed for engagement with either of the perforations for shifting the pivotal pointof the latter toward either end of the slot.
3. The combination with a bolt having a longitudinal slot and a head provided with aslot, of a link engaged with the latter and movable toward opposite sides of the head, and alocking member pivoted in the longitudinal slot to swing in either direction transversely of the bolt.
i. The combination with a bolt havinga longitudinal slot, of a locking member pivoted therein to swing in either direction transversely of the bolt, a head associated with the latter, and a weight connected with the head and movable toward either side of the latter for initiating the direction of movement of the locking member.
In testimony that I claim the foregoing as my own I have hereto aifixed my signature in the presence of two witnesses.
