My invention contemplates and provides a tool especially adapted for use in installing coiled tension springs in meEhanical structures.
One of the primary objects of the invention is to provide a' tool by means of which the hooked end of a coiled spring under tension may be caused toengage around a pin or post. I
Another primary object of the invention is to provide a tool by means of which the hooked end of a coiled spring under tension may be passed into an aperture in a plate, lug, flange or the like.

Serial No. 575,255.
Referring first to Fi s. 1, 2 and 3, the tool of my invention prefera 1y consists of a single piece of initially flat steel stock, the lateral edges of the tool converging from a relatively wide end to a relatively narrow end. One face of the tool has been indicated by reference numeral 10 and the other by reference numeral 11.
In its face 10 the tool is provided with a groove 12 extending from the approximate middle of the tool to the extremity of the narrow end thereof. The tip 13 of the narrow end of the tool is of somewhat less width and thickness than is the proximate portion of such narrow end, to facilitate the insertion of said tip into a spring receiving aperture and to provide a shoulder 14 adapted to engage the edge of a spring receiving aperture,as presently will be explained. That surface of the tip 13 which is visible in Fig. 2 preferably is semi-circular in transverse section, and if desired, may be hollow round, as most clearly appears in Figs. 4 and 5.
The lateral edges of the face 11 preferably are somewhat rounded, as indicated at 15, 15, to facilitate slippage of the hooked end of a spring under tension while being placed into operative relation with its .coo crating post,as presently will be explained Notches 16, 16 are formed in the face 10 at the point where the body of the tool merges into its reduced tip 13 the notches 16, 16 in effect constituting a transverse groove intersecting the longitudinal groove 12.
The wide end of the tool may be notched at 17 to provide a hook 18 laterall beveled to a point 19, the adjacent end 0 the tool being oblique to its lateral edges as illustrated.
At A and B in Fig. 4 I have illustrated pins or posts of a kind found in many types of machines, these pins or posts being adapted to constitute abutments for a coiled tension spring C having the usual hooked end a, c. The posts may or may not be provided with annular grooves constituting seats for the spring ends.
In using my improved tool to apply the spring C to the pins or posts A and B, one hooked end 0 of the spring is engaged around in the tool.
post A, the other end 0 of the spring being hooked over the face 11 of the tool, and the narrow end of the tool being a plied to post B with one or both of the note ies 16, 16 engaging the circular edge of the post. Thereupon, with the parts in the full line positions of Fig. 3 (the post B acting as a fulcrum, and the tension of spring C tending to hold notches 16, 16 in engagement with the circular end edge of post B) the tool is moved to the dotted line position of the same figure. As this occurs, the spring is stretched and the hooked end thereof engaging the tool slips toward and off of the small end of the tool into operative engagement with post B.
At D and E in Fig. 5 I have illustrated what may be regarded as plates, lugs, flanges or the like of a kind frequently provided to receive the ends of tension springs, the said elements D and E being provided with apertures F adapted to receive the hooked ends a, c of the tension spring 0.
In installing the spring C in and between the apertured elements D and E one hooked end of the spring is inserted in the aperture of one of said elements, for instance element D, and the other hooked end of the spring is engaged in groove 12, while the tool tip 13 is inserted in the aperture of element E. Thereupon, with the parts in the full line positions of Fig. 5 (element E acting as a fulcrum and the tension of spring C tending to hold shoulder 14 in engagement with the edge of the aperture into which the tool tip is inserted) the tool is moved to the dotted line position of the same figure. When this occurs, the hooked end of the spring engaging the tool slips along the groove 12 toward and off of the tool tip into the aperture of element E.
Figs. 6 and 7 illustrate how the hook 18 of my improved tool may be employed to remove the hooked end of a tension spring from an apertured machine element D in which it engages. Other uses of the hook 18 will suggest themselves to mechanics usavin thus illustrated and described a preferre embodiment of my invention, what I claim is new and desire to secure by Letters Patent of the United States is:
1. A tool for use in installing tension springs consisting of an elongated member having one end of a size adapted for insertion into the aperture of an apertured spring abutment, said member being provided on one face thereof with a longitudinal groove of substantial length extending to the hereinmentioned end of the tool, the other face of said member being provided adjacent said herein-mentioned end of the tool with a shoulder for engagement with a spring abutment into the aperture of which the said end of the tool is inserted.
, 2. A tool for use in installing tension springs consisting of an elongated member having one end of a size adapted for insertion into the aperture of an apertured spring abutment, said member being provided on one face thereof with a longitudinal groove of substantial length extending to the hereinmentioned end of the tool, the grooved face of the tool being notched adjacent the hereinmcntioned end of the tool.
