WRENCH-TONGS.

SPECIFICATION forming part of Letters Patent No. 612,982, dated October 25, 1898.

Application iiled July 7, 1898 Serial No. 685,312. (No model.)

To @ZZ whom it may concern.-

Be it known that we, FRANK V. WHITMAN, residing at Walkerville, in the county of Silver Bow, State of Montana, and JOHN W. JAMES, residing at Duncan, in the Chickasaw Nation,- Indian Territory, citizens of the United States, have invented certain new and useful Improvements in Wrench-Tongs; and

we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to carriage-Wrenches, and more particularly to that class of wrenches which are designed to grasp the nut and retain it between the jaws after it has been detached from the axle-spindle; and the object is to provide a simple, practical, and effective device for this purpose.

To this end the invention consists in certain features of construction and combination of parts, which will be hereinafter .fully described and claimed.

The accompanying drawings show our invention in the best form now known to us; but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of our invention as set forth in the claim at the end of this specification.

In the drawings, Figure 1 is a side elevation of our improved wrench-tongs. Fig. 2 is a transverse section through the dotted line 2 2. Fig. 3 is a detail section of one of the jaws. Fig. 4 is a similar View of the lockingbolt. Fig. 5 is a horizontal section on the dotted line 5 5 of Fig. 1. Fig. 6 is another form of lock for retaining the levers in a locked position.

1 denotes the handle, and its outer end is formed with a transverse socket 2 to receive the grip-rod 3, while its opposite end is provided with a transverse orifice 4 to receive the fulcrum-bolt 5, and its immediate end terminates in an enlarged boss 6, which is provided with a transverse orifice 7, through which the rivet 8 of the encompassing jaw 9 passes.

10 represents the hand lever, which is formed with a transverse rectangular orifice 5o 12 to receive the rectangular shank 13 of the fulcru1n-bolt 5,Which is formed with a ianged head 14 to retain the lever in place.

15 represents a th Limb-screw Working in the lever, and its lower cylindrical end extends through an orifice in the shank 13 of the bolt 5, and it is prevented from Working out by a suitable nut and pin', as shown, While the fulcrum-bolt is also provided with a nut 14 for the same purpose.

The outer end of the hand-lever 10 is also provided with a swiveled jaw 15, corresponding to the jaw 9 on the handle 1, and the opposed faces of these jaws are serrated or checked to insure a firm grip on the nut when clamped between them. The longer arm of the lever 10 is provided with a transverse oriiice 16, through which a ratchet-toothed bar 17, xed on the handle 1, extends.

`18 denotes a cylindrical sleeve fixed on the handle 1, and 19 a bolt reciprocating Within said sleeve, its toe 2O projecting into the path of the teeth on the bar 17.

21 denotes the shank of the bolt 19, its outer end terminating in a handle 22 with which to manipulate the bolt. This shank is rectangular in form, and it passes through a correspondingly-shaped orifice in the outer end of the sleeve to retain the bolt in Working position. compasses the shank, and it serves to hold the toe of the bolt in engagement with the teeth on the bar.

The manner of using the wrench is as follows: The jaws are adjusted to the nut while the lever 10 is raised, and the thumb-screw 15 turned down to clamp the jaws on the nut. The hand-lever 10 is now forced toward the handle 1, so as to"tirmly grip the nut between the jaws, and the parts are rigidly locked in this position by the lockingbolt engaging'the toothed rack, and by means of the grip-rod 3 the wrench is turned to remove the nut from the spindle. The axle having been properly oiled or greased, thenut is replaced and the Wrench removed, the entire operation being performed without soiling the hands.

Having thus fully described the invention, what we claim, and desire to secure by Letters Patent, is-a `The combination with the handle 1 formed 23 represents a spiral spring which enwith the orifice 12 and the rack-bar 17, and In testimony whereof we have hereunto set provided With a swiveled jaw, of the handour hands in presence of the subscribing Witlever 10 formed with the orifice 4 and pronesses. vided with a Corresponding swiveled jaw, the FRANK V.
