COMPLETE SPECIFICATION.
Improvements in Carriage Jacks.
I, CHARLES LUCIUS BELLAMY, of Arlington, in the County of Hudson, in the
State of New Jersey, one of the United States of America, Manufacturer, do hereby
declare the nature of my invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
My invention relates especially to devices employed for removing wheels from the
axles of carriages, and supporting the same while applying oil or grease, and has for
its object the provision of a jack simple and cheap, and effective in operation.
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.
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 of the jack.
Fig. 3 is a face view of the wrench.
Like letters of reference, wherever they occur, indicate corresponding parts in all
the figures.
A is the tube or bar, preferably a tube, as the same will be found sufficiently rigid
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 projection upon the extremity of
axle C.
D is a handle, secured to the outer extremity of the tube A. E is a jaw, fixed to
tube A. F is a movable jaw pivoted in tube A, and thrown forward by a spring, G.
H is a screw projecting from tube A, and bearing a bevelled thumb screw, I, which
impinges against the inner end of the movable jaw, F. By turning the screw toward
the tube the jaw will be thrown inward, and by turning it away from the tube, the
jaw will be thrown outward, thus adjusting the wrench to the nut it is desired to
turn.
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 handle D, the wheel may be
moved along tube A, to the position shown in figure 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 the axle.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A carriage jack, in which is comprised a tube having an opening in the
extremity for engaging with the screwthreaded end of an axle, substantially as shown
and described.
2. A carriage jack in which is comprised a tube having an opening in one extremity
for passing over the screwthreaded end of an axle, and a lifting handle at the other
extremity, substantially as shown and described.
3. A carriage jack in which is comprised a tube having an opening at one extremity

page_text: for engaging with the screwthreaded end of an axle, and a wrench at the other
extremity, substantially as shown and described.
4. A carriage jack in which is comprised a tube arranged to engage with the
screwthreaded end of an axle, an adjustable wrench, and a lifting handle, all combined
and arranged, substantially as shown and described.
Dated this 27th day of May 1890.
