Description
Patented Oct. 21, 1941 Leslie G. Ehmann, Portland, Oreg., asslgnor to Electric Steel Foundry, Portlan'dyOreg a, corporation of Oregon Application August 11, 1939, Serial No. 289,545
2 Claims. (01. 59-86) This invention relates to a securing means, and has special reference to a shackle and pin type of securing means, being particularly directed to an improved locking arrangement for securing a pin against casual displacement from a shackle when in working position. i
An object of the invention is to provide a pin for a shackle and the like having mutual interlocking engagement therewith when the pin is in working position.
A further object of the invention is to provide a shackle and the like having a pin readily insertable into working position and readily removable therefrom.
A further object is to provide a shackle and the like having a pin readily inserted or removed by 7 simple manual manipulation without the use of tools and which is secure against casual and accidental displacement.
A further object is to provide a shackle and the like having a readily removable pin, the parts being of rugged construction and designed to operate satisfactorily in the presence of sand, grease, mud, or other foreign materials.
Additional objects and advantages of the invention will become apparent as the description proceeds in connection with the accompanying drawing, it being understood that the drawing is illustrative only and that various changes and modifications may be resorted to without departing from the spirit or scope of the invention; and I deem myself entitled to all such changes and modifications as fall within the scope of the claims hereto appended.
In the drawing:
Figure l is a perspective view of a shackle embodying the principles of the invention.
Figure 2 is a fragmentary end elevation of the shackle, taken from the left of Figure 1.
Figure 3 is a perspective view of the pin to be used with the shackle.
Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure 2, showing the manner of inserting the pin.
Figure 5 is a fragmentary sectional view similar to Figure 4, showing the pin inserted and rotated into working position.
Figure 6 is a fragmentary sectional view therewith and in working position.
Figure 7 is a fragmentary sectional view through the shackle, showing an eye of a cable assembled therewith and in working position.
The invention is herein illustrated as applied their extremities with aligned openings 4 and 5. The opening 4 is of generally circular form and is enlarged at its outer end as shown at 6. A
groove or slot 1 extends the length of the opening 4, and opens at its'end into the enlargement 6, the radial depth of the bottom of the slot being the same as the radius of the enlargement 6. It will be noted in Figure 2'that'slot I is angularly displaced from alignment with the arms 2 and 3 of the Shackle, for reasons presently to be described. a a
The opening 5 is also generally circular in form, but contains the inwardly-directed arcuate fin 8 extendingsubstantially 180 degrees therearound. In the embodiment illustrated, the fin 8 is axiallyspacedfrom the ends of the-opening 5, and hence from theopposite faces of the arm 3, as will be seen in Figures 1, 4 and 5. Also, it will be noted that the fin 8 in the opening 5 is disposed angularly opposite the slot 1 in the opening], This relationship is best illustrated in Figure 2, and its purpose will be presently described. a M j V Apin, such as illustrated generally at I0, is designed for use with the shackle l. The pin ID has a generally cylindrical shank H with an enlarged head I2 on one endthereof. Extending along the cylindrical surface of shank II is the projection or rib l3, said rib being of such a length, and so located on the shank thatfwhen the pin I 0 is assembled in working position in the shackle the projection 13 will be disposed between the arms 2 and 3 with suitable clearance, as best shown in Figure 5. {The width and height of the projection I3 are such as will facilitate a loose, sliding fit within the slot 7 when the pin I0 is inserted through the opening 4.
The end of the pin opposite the head l2 is formed to theshape of acylinder of reduced diameter, as shown at 14. Formed integrally .with the reduced cylindrical, portion 14 is the outwardly-directed arcuate fin or lip I5, extending substantially 180 degrees therearound, and
being in angular alignment with the projection to a shackle I having arms 2 and 3 provided at 55 1, 4 and 5, until head l2 seats in the enlarged said arm, the other of said openings containing.
an inwardly-directed, arcuate fin extending partially therearound, and a pin adapted to fit in said openings, said pin having a projection on the shank thereof insertable through said slot, said pin having a head thereon adapted to fit in said recess so as to close said slot and form substantially a smooth surface continuous with said slot extending through said one opening and opening into said recess, the radial depth of said slot not exceeding the boundary of said recess, the other of said openings containing an inwardly-directed, arcuate fin extending partially therearound, and a pin adapted to fit in said openings, said pin having a projection on the shank thereof insertable through said slot, said pin having a head thereon adapted to fit in said recess soas to close said slot and form substantially a smooth surface continuous with said outer surface of said one arm, said pin terminating in a reduced portion having an arcuate fin extending partially therearound and adapted to form substantially a smooth surface continuous with the outer surface of the other arm, said shank extending into and being of a size to fill the other of said openings.
