COMPLETE SPECIFICATION.
Improvements relating to Supports for Cycles.
;
I, LUCIEN STEPHEN CRANDALL, of 62 Moor Street, in the City of Birmingham,
Engineer, 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:-
a
This invention relates to cycle. mounts and rests, or devices for sustaining
bicycle in its upright position, such as described in the Specifications Nos. 16915
of 1895 and 20812 of 1896 on which Letters Patent have been granted to me.
The object of my present invention is to simplify the construction of the mounts
and rests and render them more convenient and efficient in service.
In the two accompanying sheets of explanatory drawings to be hereinafter
referred to:-
Figure 1 on Sheet 1 is an end elevation, Figure 2 a side elevation, and Figure 3
a plan of my improved mount and rest.
Figures 4 and 5 are detail views illustrating the double action spring for
retaining the rest either in or out of position as required.
On Sheet 2, Figure 6 is an end elevation and Figure 7 a side elevation illustrat-
ing a modified arrangement of the mount and rest; Figure 8 is a detail view of
a double acting spring suited to such an arrangement, and Figure 9 a front
elevation of the pivotted joint.
The same reference letters in the different views indicate the same parts.
Referring to Sheet 1 the body A of the mount or rest consists preferably of an
aluminium casting, with tubular legs as B3 having screwed and flanged terminal
pieces C for more effectually supporting the machine on soft ground and also for
enabling the height of rest to be adjusted to suit different machines. At the upper
part of the body A, I pivot the clip base D to which is attached by the screw or
stud E the clip cap F. The adjacent faces of the clip base and cap are formed
suitably for clamping upon the back stay tubes G of the bicycle frame to which
the mount and rest is to be attached. Such attachment is effected by screwing up
the stud E and thus by drawing the base D and the cap F towards each other to
clamp them.upon the tubes G. One side of the clip cap and base is provided with
an open jaw, as illustrated at the right hand of Figure 1, to enable the rest to be
clamped to stay tubes having a slightly varying pitch or distance between their
centres. One side of the upper face of the cap F is formed to serve as a step, as
illustrated at Figure 3, for convenience in mounting the machine or dismounting
from the same.
When the rest is in service for supporting the machine it occupies the position
shown by the full lines at Figure 2, in relation to the tubes G, but when out of
service it assumes the position shown by the dotted lines. The appliance is
maintained at each of such portions, until forcibly removed therefrom, by the
double acting spring H. When the rest is in its service position, as shown at
Figure 4, its accidental movement in the direction of the arrow is prevented by
the resistance of the spring H, whilst movement in the opposite direction is

page_text: checked by the contact of the stop a (formed on the body A) against the clip
base D. But when not required the rest can be forced against the action of the
spring H, (either by the hand or by the movement of the machine whilst the
terminal pieces are in contact with the ground) to the out-of-service position
shown at Figure 5, and by dotted lines at Figure 2 and the spring H then assumes
such a position as to prevent accidental movement in the direction of the arrow
shown at Figure 5, whilst movement in the opposite direction is prevented by the
contact of the stud a¹ against the clip base D.
With the arrangement shown on Sheet 2 I am enabled to obtain a wide spread
of the tubular legs B, when necessary, without fouling the pedals during their
revolution. The clip base D and the body A¹ are connected to opposite ends of
the tube J instead of directly to each other as in the arrangement hereinbefore
described. The lower end of the tube J has a socket J¹ secured with it, and the
connection between such socket and the body A¹ consists of a pivot joint on which
the lower part of the appliance can be moved to its in or out of service position
as required. The double acting spring H¹ is arranged within the tube J and its
lower end abuts against the internal projection a² from the body A¹. The two
positions of the body part and of the spring are indicated at Figure 7. The
movement in the one direction is limited by the abutment of the projection a³
from the body part against the projection from the socket J, and in the other
direction by the abutment of the part at (Figure 8) of the inner projection a² of
the body A¹ against the inner surface of the tube J.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. Cycle mounts and rests substantially as described and as illustrated.
2. A cycle mount and rest comprising a body part A pivotted to an attachment
upon the cycle frame and having legs B with adjustable terminal pieces C,
substantially as described and as illustrated.
3. A clamping device for cycle mounts and rests comprising a base I) with 3
clip cap F capable of being drawn together by the tightening of a stud E and
clamped upon tubes as G, the base having the mount and rest pivotted to it, and
the cap formed to serve as a step, substantially as described and as illustrated.
4. In combination with a cycle mount or rest having a body part as A¹ with
legs and terminal pieces, a connecting tube J having a socket at its lower or 3
pivotted end and connected at its upper end to a tube clamping device, substantially
as described and as illustrated.
5. The use of a double acting spring for cycle mounts and rests, substantially
as and for the purposes described and as illustrated.
