UNITED STATES PATENT OFFICE.

CHARLES L. BELLAMY, OF ARLINGTON, NEW JERSEY.

CARRIAG E -JAC K.

SPECIFICATION forming part of Letters Patent No. 425,?28, dated April 15, 1890.

Application filed November 13, 1889. Serial No. 330,112. (No model.)

employed for removing wheels from the axles of carriages and buggies, and supporting the same while applying oil or grease, and has for its object the provision of a jack simple and cheap to construct and effective in operation.

To attain the desired end, my invention consists, essentially, in a tube or bar having an opening in the extremity for passing over or engaging with the screw-threaded end of an axle and in certain novel and useful combinations or arrangements of parts, and peculiarities of construction and operation, all of which will be hereinafter first fully described, and then pointed out in the claims.

.In the drawings, Fig. 1 is a view of my improved jack, illustrating the use of the same. Fig. 2 is a longitudinal sectional view. Fig. 3 is a face View of the wrench.

Like letters of referencewherever they occur indicate corresponding parts in all the figures.

A is the tube or barpreferably a tube, as the same will be found sufficiently strong and much lighter than a bar. The end of tube A is open at B, and may be screw-threaded or made smooth within to pass over the screwthreaded projection upon the extremity of an axle C.

D is a rotatable handle provided with a screw-threaded projection E, engaging-with the extremity of the tube opposite to B and carrying an adjustable jaw F.

G is a jaw fixed upon tube A.

When constructed and arranged in accordance with the foregoing description, my improved jack will be found admirably adapted to the uses and purposes for which it is intended. The wrench may be employed for removing the nut from the axle, and after this is done the end B of tube A is passed over the projection from which the nut has been removed, and by lifting slightly upon the handle D the wheel may be moved along tube A to the position shown by the dotted lines in Fig. 1. The axle may be oiled and the wheel pushed back to place with the greatest ease and expedition, while there is no danger of dropping of the axle.

If desired, the wrench portions of the device might be dispensed with and the handle D applied directly to tube A, making a very cheap, simple, and compact jack.

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

1. As a new article of manufacture, a carriage-jack in which is comprised a tube having an opening in the extremity for engaging with the screw-threaded end of an axle, substantially as shown and described.

2. As a new article of manufacture, a carriage-jack in which is comprised a tube having an opening in one extremity for passing over the screw-threaded end of an axle, and a lifting-handle at the other extremity, substan tially as shown and described.

3. As a new article of manufacture, a carriage-jack in which is comprised a tube having an opening in one extremity for engaging with the screw-threaded end of an axle, and a wrench at the other extremity, substantially as shown and described.

4. As a new article of manufacture, a carriage-jack in which is comprised a tube arranged to engage with the screw-threaded extremity of an axle, an adjustable wrench, and

a lifting-handle, all arranged substantially as shown and described.

5. The combination, with the tube, of .the fixed jaw, the movable jaw, and the rotatable handle .en gaging with the screw-thread in the tube and carrying the movable jaw, substantially as shown and described.

Signed at New York, in the county of New York and State of New York, this 8th day of November, A. D. 1889.

CHARLES L. BELLAMY.
