Improvements in Means for Mounting the Wheels of Vehioles.
I, ROBERT HÖFER, of the Firm of Robert Höfer & Co., of Nordhausen am
Harz, Germany, Manufacturer, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to provide a detachable axle-holding device for
vehicles which will enable the corresponding wheel-axle to be disconnected from
the frame of the vehicle without, as has hitherto been usual, removing the axle-
nut and dismounting the axle, whereby, as is well known, the exact re-adjustment
of the axle is often rendered difficult.
In the accompanying drawings,
Fig. 1 is a side view of a detachable axle-holding device according to this
invention as applied to a cycle, and
Fig. 2 is a similar view showing the device detached from the frame of the
vehicle.
Fig. 3 is an end view of part of the frame of a cycle with a pair of the
detachable axle holding devices.
The axle a with axle-nuts b is held on each side by a rectangularly headed pin o,
the shank d of which is screw-threaded. On the end of the vehicle-frame e thero
is fixed a fork or bracket, which is cut out or recessed correspondingly to the
square form of the head of the pin c, which it receives. To this fork the pin o
fastened by means of its shank d and a nut g; the pin may be fastened to the
frame either above or below the axle a according to the form of the fork-end. In
order to loosen the whool from its frame e, it is moraly necessary to unscrew the
nuts g to enable the pius c with wheel axle to be removed.
This mounting-device presents the advantage that the pressure during travelling
or pedalling is received by mutually perpendicular faces of the fork
against which lie the faces cc of the pin c, which are also mutually perpendicular,
so that there is no tendency whatever to break off the pin c. The loosening of the
axle-nut b is not necessary in disconnecting the wheel-axle from the vehicle-
frame.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
1. The combination with an axle a aud the fork or bracket of the frame of a
vehicle, of detachable axle holding devices each consisting of a pin c the head of
which is adapted to receive and form a bearing for one end of the axle and to
engage in a recess in the said fork or bracket in which it is prevented from turning,
and the shank of which pin is adapted to be secured to tho said fork or bracket so
that it can be released therefrom in a vertical direction, either upwardly or
downwardly, substantially as herein before described.
2. Axle-mounting devices of the kind specified in the preceding claim, in which
the head of each pine is provided with mutually perpendicular faces c' d' arranged
to bear against mutually perpendicular faces of the corresponding fork or
bracket in order to transfer the pressure of the axle direct to the frame,
substantially as hereinbefore desoribed.

page_text: 3. The combination and arrangemont of parts constituting the improved menns
hereinbelore described with reference to and shown in the drawings annexed for
detachably mounting an axle in the frame of a vehicle for the purpose specified.
