JULIAN R. HARRISON, OF BARNWELL, SOUTH CAROLINA, ASSIGNOR OF ONE-HALFrTO JOHN M. EASTERLING, OF BARNWELL, SOUTH CAROLINA.

BOLT- HOLDING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 735,251, dated August 4, 1903. Application tiled December 10, 1902. Serial No. 134,678. (No model.)

.To all whom it may concern:

Be it known that I, JULIAN. R. HARRISON,

-a citizen of the United States, residing'at Barnwell, in the county of Barnwell and State of South Carolina, have invented a new and useful Bolt-Holding Implement; of which the and is described in the following specification.

The structure is, however, open to various modifications and changes.

In the drawings,-Figure 1 is a perspective view showing theimpleinent applied to a vehicle-wheel and engaged with a tire-nut. Fig. 2 is also a perspective view illustrating the invention in use upon a vehicle-thill.

' Fig. 3 is a transverse sectional view through one endof the lever-arm, and Fig. 4 is a sectional View through an intermediate portion of the arm.

Similar numerals of reference designate corresponding parts in all the figures of the drawings.

In the embodiment shown a lever-arm 10 is employed, which may be of any desirable form, preferably having an ofiset neck 11 at one'end, provided with an enlarged head that has a threaded opening 12. In this opening is threaded a rotatable shank 13, on the ends of which are arranged attaching elements in the form of jaws 14 and 15. .The jaw 14 is preferably formed with a fiat innerface 16 and a terminal lip 17, while the jaw 15 is in the form of a hookthat is, substantially semicircular in shape. The lever-arm'lO is also provided With an intermediate angular opening 18, in which is detachably fitted a reversible holding device comprising, essentially, an angular stem 19, having article-engaging heads at its ends. One of these heads comprises an enlargement 20-, having a cupped terminal 21, the peripheral edge of which is serrated to provide the teeth 22. The inner end of the head constitutes a shoulder 23, which rests against the lever-arm and prevents the movement of the stem through the opening 18. The other end of the stem is sharpened, as shown at 24, to provide a chisel-edge. The holding device is held in place by a set-screw 25, threaded into the lever-arm and arranged to engage in a socket 26, formedin the stem.

The manner of using this implement will be apparent to those skilled in the art by reference to Figs. 1 and 2. If the article to which it is to be attached has a rounded contour-as, for instance, the felly of a wheel the hook 15 is engaged therewith, the shank 13 being first adjusted so that the holding device will be brought into proper relation with the bolt to be held and the chisel edge will engage the same. In case a bolt having a rounded head is to be held and the face engaged by the jaw is fiat the jaw 14 is employed, as shown in Fig. 2. In this instance the cupped head will center itself upon the bolt -head and the teeth will bite into the same, thus insuring the holding of the bolt. If a round-headed bolt is located in an article having a rounded surface, it will be apparent that by reversing the holding device the hook .15 and cupped head will be brought into 00-,

in the lever-arm and also relieves the setscrew 25 of the twisting strain.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art with out further description, and it will be underand an article-holding device carried by the arm.

2. In an implement of the character described, the combination with a lever-arm having a threaded opening through one end, of a shank threaded through the opening and freely rotatable thereon, said shank carrying a terminal attaching element, and an articleholding device secured to the arm intermediate its ends- 3. In an implement of the character described, the combination with a lever-arm having an olfset end provided with a threaded opening, of a shank threaded through the opening and carrying an attaching-jaw, and an article-holding device secured to the arm at one side of the olfset end.

4. In an implement of the class described, the combination with a lever-arm, of attaching-jaws carried by the arm and located on different sides thereof, and article-holding devices also carried by the arm and coacting respectively with the jaws.

5. In animplement of the character described, the combination with a lever-arm, of attaching-jaws carried by the arm and located on difierent sides thereof, and article-holding devices also carried by the arm and coacting respectively with the jaws, said devices being reversible, so that they may be placed in coacting relation with diiferent jaws.

6. In an implement of the character described, the combination with a lever-arm, of spaced attaching-jaws carried by the arm and arranged on different sides thereof, and an article-holding device secured to the arm.

7. In an implement of the character described, the combination with a lever-arm, of spaced differently-shaped attaching-jaws carried by the arm, and an article-holdin g device also carried by the arm.

8. In an implement of the character described, the combination With a lever-arm, of spaced attaching-jawsrevolubly connected to the arm, and an article-holding device carricd by the arm.

9. In an implement of the character described, the combination with a lever-arm, of a shank having a threaded engagement with the arm, differently-shaped jaws secured to the shank on opposite sides of the arm, and an article-holding device secured to the leverarm.

10. In an implement of the character described, the combination with a lever-arm, of a shank having a threaded engagement with the arm, dilferently-shaped jaws secured to the shank on opposite sides of the arms, and a holding device secured to the lever-arm and having oppositely-projecting article-engaging heads.

In testimony that I claim the foregoing as my own I have hereto aifixed my signature inthe presence of two witnesses.
