WILLIAM A. STOWELL, OF MONTPELIER, VERMONT.

COMBINED CARRIAGE JACK AND WRENCH.

SPECIFICATION forming part of Letters Patent No. 543,660, dated July 30, 1895.

Application filed January 20, 1894. Serial No. 497,842. g (No model.)

To ail whom it rmay concern:

Be it known that 1, WILLIAM A. STOWELL, a citizen of the United States, residing at Montpelier, in the county of Washington and State of Vermont, have invented a new and useful Improvement in a Combined Carriage Jack and Wrench, of which the following is a specification, accompanied by drawings forming a part of the same, and in which Figure 1 represents an apparatus embodying my invention and represented as applied in the removal of a nut from the axle of a carriage and illustrating its use as a wrench. Fig. 2 represents the apparatus as applied to the axle for the purpose of lifting the wheel from the ground in order to allow the same to be removed from the axle. Fig. 3 represents the axle supported by the apparatus resting upon the wheel which has been removed from the axle. Fig. 4 is a sectional view on line 4 4, Fig. 1. Fig. 5 is a perspective view of the jaws formingthe wrench and the central section of the bar supporting the same. Fig. 6 is a longitudinal sectional view of the movable jaw. Fig. 7 is a detached View of the bent U-shaped elastic wire forming the spring by which the pivoted handle is retained in position. Fig. 8 is a view of the central portion of the lever A with the jaws of the wrench and a pivoted handle which is shown in central sectional view, and Fig. 9 is a detached view of the pivoted handle.

Similar letters refer to similar parts in the different figures.

My invention relates to that class of carriage-jacks which is adapted to support the axle of the carriage and rest upon the wheel after it is removed from the axle; and it consists in the construction and arrangement as hereinafter described, and specifically set forth in the claims, and, also, in the combination, with the jack, of a pair of jaws adapted to engage the carriage-nut, with means for actuating the same, and of a handle coincident with the axis of rotation of the jaws in the operation of unscrewing the nut, whereby the jack is capable of being used as a wrench for the purpose of removing the nut from the axle.

Referring to the accompanying drawings, A denotes a lever curved at its ends and provided with feet A and A each having a dovetailed recess A adapted to receive and hold the. elastic rubber blocks A A Near the central section of the lever A, and preferably integral therewith, is a fixed jaw B, and a movable jaw B, adapted to slide along ways B on the lever A and actuated by a screw B which is held from longitudinal movement by ajournal-bearing B and is provided with a handle B by whichthe screw is rotated.

C denotes a handle having one end bifurcated to inclos'e the lever A, to which it is pivoted by a pin 0'.

The lever A is provided with a mortise D, havingin one side a small notch D to receive a U-shaped spring D bearing against spurs D upon opposite sides of the lever, and with the free ends D D of the spring bearing against the end of the pivoted handle 0.

When the apparatus is used as a wrench, the handle 0 is turned upon its pivot 0 from the position shown in Figs. 2 and 3 to that shown in Fig. 1, the pressure exerted by the spring D upon the bent end of the handle C serving to hold the shoulder 0" against the edge of the lever A and maintain the handle a C in a position at right angles with the lever A, and in a line substantially coincident with the center of a nut held between the jaws B B.

The apparatus held by the handles B and O is applied to the nut E, which is clamped between the jaws B B. A whirling motion is given to the lever, causing it to rotate upon the handle 0, as held in the hand of the op erator, in the proper direction to unscrew the nut E. After the nut E has been removed from the axle it is held between the jaws B B', tl1e handle C isthen turned on its pivot into the position shown in Figs. 2 and 3, in which position it is held by the pressure of the spring B upon the side 0 holding the handle against the edge of the lever A, which enters a groove 0 in the handle. The foot A is placed upon the top of the axle F and the hook G hooked beneath the axle, so that when the lever A is raised by the handle B, as shown in Fig. 2, the wheel F will be lifted so as to clear the ground. The wheel is then removed from the axle, as shown in Fig. 3, and brought into proper position to receive the foot A which rests upon the hub F and supports the weight of the axle, as shown in Fig. 3. The hook G is pivoted to a screwthreaded bolt G, which is screwed into the lever A at G and carries a check-nut G the end of the screw-bolt G being inclosed within the mortise G in the lever A. By loosening the check-nut G the screw-bolt can be rotated half a revolution to bring the hook G upon either side of the axle, thereby making the hook a right or left hand book, as desired; or the screw-bolt G can be raised or lowered within the lever A, so as to adjust the position of the hook.

The spring D consists of a single piece of steel wire bent into a U-shaped piece, which is passed through the mortise D and inserted into the notch D with the free ends bearing upon the end of the handle 0, and with the spring held from rotation in the notch D by the spurs D projecting from the sides of the lever A.

I am aware that a carriage-jack adapted to rest at one end upon the top of the axle and at the opposite end at the hub of the removed wheel and having a hook to engage the axle is not new, and I do not claim such broadly;

but in such a carriage-jack two hooks were used, one of which was rigidly suspended from the lever extending down at one side of the axle and the other was pivoted, so as to move in a plane at right angles to the lever and extending down upon the opposite side of the axle, the axle being inclosed between the two hooks. I employ onehook only, which I pivot to the screw-threaded bolt G, so the hook can move in a plane parallel with the lever, in order to permit a slight swinging motion to the hook parallel with the axle and lover, as the lever is raised by the handle 13, and the screw-threaded bolt G allows the adjustments in the hook, as already described.

I am also aware that carriage-jacks have been provided with means for withdrawing the nut from the axle, or have had a socket attached to the jack adapted to receive the nut; butmy present invention provides means for holding the nut co-operatively combined with the lever of the jack,furnishing a wrench and a carriage-jack in a single tool.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of a lever A having a handle 13 projecting from one end of said lever with its axis parallel with said lever, a pair of jaws carried by said lever midway its length and a handle 0 attached to said lever opposite said jaws and arranged to be held with its axis at right angles to said lever, whereby said lever is rotated about the axis of said handle 0, by means of said handle 13, substantially as described.

2. The combination of a lever A provided with a journal bearing B at oneend of said lever, a fixed jaw B carried by said lever midway its length, a movable jaw capable of sliding along said lever and provided with an internal screw thread, a spindle B journaled in said fixed jaw and in the journal bearing B and provided with a screw thread engaging the screw thread in said movable jaw anda handle attached to said spindle and projecting beyond the endot' said lever, substantially as described.
