COMPLETE SPECIFICATION.
An Improved Construction of Wheel Naves.
I, EUGENE DE JORDAN, of the Town of Wojnitz, in the Austro-Hungarian Empire,
Engineer, do hereby declare the nature of my said 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 to an improved construction of the naves of wheels, the
object of the saine being to reduce the contact surfaces of the carriage or other
vehicle axle and the nave, to thus reduce the quantity of lubricant required and
to render the necessity of lubricating the carriage or other vehicle more seldom. In
order to attain my object the axle and nave are constructed as represented in the
accompanying drawing and described in the following specification, in which
Figure 1 is the section of the nave of a wheel constructed on my improved system,
and
Figure 2 is a part elevation and part vertical section of the same.
The journal of the axle a is made in the form of a flat threaded screw, onto which
the nut like bearings b and c are so screwed that a small space remains between the
same, the nearest edges of which are bevelled off so that the said edges form a
wedge like channel. The journal box e is screwed into the nave d and is provided
with a dovetailed groove, into which a wedge-like ring fis inserted. This ring fits into
the corresponding channel in the nut like bearings b, c, of the journal of the axle a
and consists of six or more sections. In this manner the friction between the nave
and the axle is reduced to a minimum. It will be evident that steel of best quality
ought to be employed for making the ring f and the nut like bearings b, c.
account of the axle being supported in this manner a larger space remains between
the nave and the axle, and when the caps g and are screwed onto the journal
box e a space is attained which is capable of receiving a considerable quantity of
lubricant.
On
The reduction of the frictional surfaces will alone produce a considerable saving
of lubricant, and when the space which is suited for receiving a large quantity of
lubricant is also taken into account it will be evident that the wheels will very
seldom require lubricating. A further advantage attained by my construction of
nave and axle is that the separate parts are connected by means of screws and that
the parts subjected to the most wear and tear are composed of several pieces so that
should the same become worn and broken the parts can be readily and rapidly
replaced at a trifling expense and with little trouble.
Having now particularly described and ascertained the nature of my said inven-
ion, and in what manner the same is to be performed, 1 declare that what I
laim is :-
My improved construction of the naves of wheels, according to which a ring f
of wedge-like section composed of several parts is arranged in the journal box e
nd rests against the bevelled edges of bearings h, c, screwed onto the journal of the
xle, whilst in the interior of the nave and around the nut-like bearings b, c, a
ufficiently large space is attained for receiving a considerable quantity of lubricant,
ubstantially as and for the purpose specified, and shown.
Dated this 30th day of January 1800.
