seria No. 392,317. N0 moan.)

To all whom/ i may concern,.-

Be it known that I, DUNCAN A. MCTAVISH, a citizen of the United States, residing at fest Bay City, in the county of Bay and State ofMichigan, have invented certain new and useful Improvements in lVagon-Jacks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in wagon-jacks; and it consists in the combination, arrangement, and construction of the parts 'with the object of producing a-device for lifting wagons which can be used by a per1 son standing at the outer side of the wheel, whereby the trouble of passing behind the wheel for adjusting' and operating the jack is avoided.

Another object of the invention is to construct a light and durable wagon-j ack which, while being effective and easy of operation, is at the same time cheap and simple in its adjustment and operation.

My improved wagon-jack is illustrated in the accompanying drawings, in which the same letters of reference will be found indicating the same parts or elements throughout the several views.

Figure l represents a lateral side View in elevation of my improved wagon-jack, showing the parts in position when lifting a wheel and with the axle in transverse section. Fig. 2 isa rear side View of the same. Fig. 3 is a top or plan view of the same. Fig. 4: is a section of Fig. l, taken at 0c.

a represents a foot-piece which rests upon the floor or ground, and b is avertical standard with its lower end permanently secured to the foot-piece and to the upper end of the standard is permanently securedthe front and rearwardly-extending arms c and CZ, the outer portions of the arms being also curved upwardly. The arm c is provided upon one side with ratchet teeth or notches e.

fis a lever with one end g pivoted to the upper end of the arm d by a bolt h, the end being provided with a fork which extends on both sides of the arm, while the opposite end of the lever, extending to a suitable distance beyond and beside the arm c, is provided with a handle t', while the portion j, passing the arm c, is arranged to engage with the teeth e, and this part y' is provided with a guard-piece 7c, which extends across the opposite side of the arm, leaving a sufficient opening Z between the arm and the guard to allow the lever to pass the notches or teeth e, when required. The central portion of the lever between the arms c and d is provided with an elongated vertical opening n, and through this opening 6o is passed the upper end portieri of a vertical bar o, which is provided with a series of openings p, and a pin q is passed through suitable openings in the lever, and also through one of the openingsp for retaining the parts in position. The lower portion r of the bar is extended downwardly beside the standard b, and is providedon its lower end with a transverse lifting-piece s, having a vertical opening t, through which passes the 'stand- 7o ard, the opening being arranged so that the piece will easily move upon the standard, but still be retained against lateral movement.

In operating the device the lever is released from the notches e and allowed to move down-` ward until the inner side of the guard lc rests upon the curve of the arm. The vertical bar 0 is then adjusted to bring the lifting-pieces beneath the axle carrying the Wheel to be removed or operated upon. The pin q is then 8o passed through the required opening p, and the handlet is then raised, which also lifts the vertical bar and the piece s and the axle to the requiredA height. The lever is then moved laterally andrthe portion j engaged with the proper notch e, and the parts will then be retained for manipulating the wheel, as desired.

It will be noticed that the construction shown allows the parts to be operated by 9ol reaching over the wheel, as the adjustingpin q may be manipulated for adjusting the lifting-piece, as also may the lever be operated by raising or lowering the axle with great ease and rapidity by the workman standing upon the front side of the wheel, so that n it is not necessary to pass behind the wheel in order to operate the jack, and, also, the jaclrmay be placed between the axles, and

then after operating upon one axle the jack roe` may be moved directly back and engaged with the other ax'lewithout removing the j ack from behind the Wheels, whereby a great saving of time and laboris accomplished, besides making a device which is light and easily operated and which can be sold for a loW price.

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

The combination, in a Wagon-jack, of the vertical standard having upon its lower end a foot-piece and provided upon its upper end with outwardly and upwardly extending arms c and d, the arm c being provided with ratchetteeth e on its side face, a lever with one end pivoted to the said arm d and with its opposite end extending beyond the arm c and en-
