COTTER KEY FULLER Filed July 11, 1929 0. H. pwm; GENT/1M.
alike 1mm Patented June 30, 1931 UNITED STATES PATENT OFFICE CARL H. BUCKLE AND GUS R. MCPI-IAIL, OF IVIAGNOLIA, TEXAS COTTER KEY PULLER Application filed July 11,
This invention relates to a cotter key puller and aims to provide a novel, simple and highly efiicient device of this kind which may be carried in and actuated by one hand to effect engagement with and the withdrawal of a cotter key.
Another object is to provide a puller of this character in which the parts are compactly arranged in order to permit the withdrawal of cotter keys located in confined places and usually difficult of access.
Another object is toprovide a novel construction whereby improved levers for eifective operation of the puller is attained and wherein the parts may be readily disassembled for inspection, repair or the like.
Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.
In said drawings Figure 1 is a view in elevation of the invention,
Figure 2 is a side elevation of the same,
Figure 3 is a longitudinal sectional view taken on the line 3-3 of Figure 1,
Figure 4 is a cross sectional view taken on the line 44 of Figure 1, and V Figure 5 is a cross sectional view taken on the line 55 of Figure 1.
Referring specifically to the drawings, the extractor comprises a tube 10, from the inner end of which arms 11 rigidly extend. The forward end of the tube is notched as at 12. Slidably mounted within the tube is an extracting rod 13 provided with a hook 14 to coact with the end 12 of the tube. In order to provide for steady and eflicient operation of the extractor rod 18, the same has a central enlargement or guide construction 15, intimately fitting the bore of the tube 10.
Pivoted to the ends of the arms 11 as at 16, are handles or levers 17. These handles or levers 17 have links 18 pivoted thereto at 19 1929. Serial No. 377,492.
and which are pivotally connected by a bolt at 20 and which also connect them to the inner end of the extractor rod 13. A latch 21 is provided on the extractor rod 13 and a lug 22 is formed on the tube 10. A contractile 550 spring 23 is attached to the lugs 20 and 22, serving to normally hold the parts in and restore them to the position shown in Figure 1.
In using the invention, both elements 17 are gripped in one hand and the hook 14 is engaged with the cotter key or object to be extracted, whereupon the arms 17 are pressed together at their free ends, resulting in relative movement of the hook 14 and end 12 whereby the cotter key is gripped and may be pulled, since the links 18 tend to move rearwardly at the center and the extractor 13 to correspondingly be moved thereby against the tension of the spring 23, such spring 23 55 restoring the parts to the position in Figure 1 after an operation. 7
Various changes may be resorted to provided they fall within the spirit and scope of the invention.
We claim as our invention 1. An extractor of the class described comprising a tube, levers pivoted to the tube, an extractor member slidable in the tube and jointly with the tube adapted to directly engage a cotter, links pivoted to the levers and to said member, the pivotal connection with said member being normally rearwardly of a line passing through their pivotal connections with the handles, said extractor having a hook at the forward end, an enlargement on the extractor withinthe bore of the tube, and a contractile spring connecting the tube and said extractor.
2. A tool olthe class described having a tube, arms extending laterally therefrom, an extractor hook slidably mounted in the tube, said tube and extractor hook being jointly and directly engageable with a cotter, said hook having an enlargement engaging thew bore thereof, a contractile spring connected to the extractor member and to the tube, levers pivotally connected to the ends of said arms, said levers extending rearwardly, links pivoted to the levers, said links being pivoted together rearwardly of their connection to the levers.
In testimony whereof We aflix our signatures.
