Application April 7, 1950, Serial N 0. 154,556

2 Claims. 29-227) This invention relates to means for releasing a spring, such for example as the spring associated with an automobile hood, and has for its principal object the provision of a spring handling tool which can readily and easily be in serted in the spring when the hood is raised so that when the hood is lowered the tension of the spring is released on both sides of the tool and with perfect safety as the spring is locked to the tool, thus permitting the workman to reach under the hood and unfasten the spring from either end, either the hood end or the body end.

In the drawings:

Fig. 1 is a side view.

Fig. 2 is a front view.

Fig. 3 is a top plan view.

Fig. 4 is a detail.

The body of the tool is a sheet of number 16 gage steel bent to form a semi-cylinder I0 having four integral guiding portions ll, slightly flared outwardly as at l2 and sloping centrally toward the main body portion ID by the angular edges l4. For a 1%" diameter spring the inside diameter of the body would be 1%" and the flared portion would be a half inch beyond the axial plane, the more readily to guide the spring into the body cavity.

At each end -of the body [0 there is a head It tilted at an angle of 5 and brazed in place to leave a space ll of about a quarter inch at top and bottom. These two heads [6 project beyond the axial plane by therefore extending beyond the central vertical edge I8 of the tool.

A spring clip 20, having a finger piece 2| and a free end 22 oscillates about the central section of the body, being held in place by a pair of flat head rivets 23 carried by the body l0 and received in the slot 25, starting 40 from the end 22 at the point 26 and extending 186 to the point 21. When the spring 30 is within the body [0 as in Fig. 2 and engaging the two heads It, the clip 20 is closed on the spring by moving the finger piece 2| away from the open side, or counterclockwise as seen in Fig. 3.

What I claim is:

1. A spring handling tool including a semicylindrical body having four integral guiding portions, each guiding portion having a sloping edge extending outwardly from the central portion of the body to a point short of the proximate end of the tool, a head spaced inward from the two opposite ends of the body and extending partly into the guiding portions, a spring clip extending around the central portion of the body inside of the four extended portions, said clip having a central slot therein, and securing means, carried by the body, extending within the slot to guide and limit the movement of the clip so as to look a spring in place when the clip is revolved to close the open side of the body.

2. A spring handling tool including a body curved to semi-cylindrical shape with an open side to receive in the body a helical spring of about the same diameter as the inside of the tool, a head near each end of the body, a slotted clip centrally surrounding the body, and securing means, carried by the body, extending within the slot to guide and limit the movement of the clip so as to look a spring in place when the clip is revolved to close the open side of the body.
