. TO' ALL WHOM IT MAY CONCERN:

Beit known that L'Gnoncn W, PnELPs, ofiOonneant, in the county of Ashtabula, and State of Ohio, have invented new and useful Improvements in Bolt-Holders; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

'This invention consists in an improved device orholding bolts rmly, for the purpose of turning the` nut on or oil. I

The construction and manner of operation will be fully described hereinafter.

Figure 1 represents a. perspective view of myimproved device, and

Figures 2 and 3 views of parts detached.

In the drawings- A represents a lever, provided with the square head al, in which is inserted the shank b, of the steel wedge b', which latter rests upon the head ofthe bolt when in operation.

e represents a catch or button, pivoted at "c1,`the free end of which fits into a notch in the upper 4end ofthe shank of the 'wedge b. This catch is arranged so as to swing aside, when desired, and permit the shank b to drop out. l

, a2 a3 represent slots in the lever A, -ih the former of which is placed the transversepin a4, as shown. In tlie latter is pivpted the notched har E.

D represents a lever, which terminates at one end in the handle cl, and at the other in the half circle oZ.

D represents a bar, rigidly attached to one side of lever D, which bar is provided at regular intervals with the hooked notches d2. When in place, the end of the bar D is passed through the slota, of lever A, and is secured therein by means of the pin cl3. i

E represents a notched bar, one end of which is pivoted in the slot a3, of the leverA, the other of which moves freely up anddown in the slot oZ, of bar D. This slot is inclined upon ehe side, for the purpose of holding the teeth of the bar E.

From this description, the operation of my invention will be readily understood. s p

The levers AD having been set at the proper distance apart to take in the bolt readily, which adjustnient is easily made, by hooking any one of the notches d2 over the pin a4, of the slot a2, the sharp wedge of the lever A is placed upon the head et the bolt, and the handles of the levers drawn apart. When the bolt is rmly clamped, the proper tooth of the bar E is allowed to engage with the side of the slot cZ, by which means the levers are securely retained in the desired pos'ition.` .The nut is then turned on or olf, as may be desired,

the seuiicircle'cl1 permitting awrench or other instrument to be readily used. By the arrangement of the button c, the wedge may be easily changed for one of a different size, or it may be removed for the purposes of sharpening, Sie. I t

This device may be usedlfor holding bolts of any kind, but it is especially useful in cases where round bolts are used, as in fastening wagon-tires.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The holt-holder, consisting of the lever A, wedge b', button c, lever D, bar D', and bar E, constructed and arranged as herein described. i

This specification signed and witnessed, this eleventh day of May, 18.68.
