Specification of Letters Patent.
Patented Apr. 26, 1921.
Application filed April 17, 1919. Serial No. 290,753.
To all to [won it may concern:
Be it known that I, WALTER R. GREEN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bicycle Luggage'Carriers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.
This invention relates to cycle carriers of the type adapted to extend backward from the rear fork over the rear wheel. Hitherto carriers of this type have been connected at the front ends by clamps to the rear fork at a point intermediate the seat supporting column and the mud guard and have been held in position thereon solely by the friction of the clamp with the fork.
Further, in such clamps there has been no support for the platform intermediate its front and rear connections to the cycle frame.
One of the principal objects of the invention is to provide means for securing the front end. of the carrier not only to the vertical member of the rear fork, but also to the cross member extending therebetween which carries the mud guard thereby preventing any side sway or tipping movement of the carrier as well as any vertical movement of the carrier relatively to the rear fork.
A further object of the invention is to provide a more rigid form of carrier than has been possible hitherto without increasing the weight to an excessive extent.
It is also an object of the invention to provide a tubular form of construction for carriers.
Another object of the invention is to provide a carrier supported throughout a part of its length by the mud guard.
The invention also has other important objects which will be apparent from the disclosures in the specification and drawings.
The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

r s shown on the drawings:
The carrier comprises a platform generally designated as 1, secured at its front edge to the rear fork 2 of the cycle frame 3. The rear end of the carrier platform is supported by arms 4, directly connected at their lower ends to the axle 5, of the rear wheel. The platform may be conveniently formed of metal tubes 6, flattened at each end for attachment to cross pieces 7 and 8. Intermediate these cross pieces are arranged braces 9, each prefera ly formed as shown in Fig. 4, of a single strip of metal folded around the tubes with its ends meeting in the middle of the platform. The portions of these strips between the tubes 6, are riveted together so that the latter are firmly held together by the two parts of the bracing strips.
The forward cross piece preferably consists of angle-iron having one flange 10 riveted to the ends of the pipes 6, while the other flange 11 abuts against the fork 2.
To stiffen the carrier so that it can sustain a very heavy weight without bending or. distortion the carrier is given an arched form. This is preferably carried out by bending the forward portions of the tubes 6 to fit the adjacent curved surface of the mud guard 14:, so that the platform may rest thereon for additional support. In view of this curvature the forward edge of the platform is substantially perpendicular to the fork 2, so that the flange 11, of the angle-iron is adapted to lie flush against the fork 2.
This flange is held in contact with the fork 2 by means of a channel bar 12, ar; ranged on the opposite side of the fork and c innected to the flange 11 by bolts 13.
The curving of the forward part of the platform not only enables the mud guard to support the platform throughout a portion of its length but in addition aids in the connection of theforward end of the carrier not only to the side members of the fork 2, but also to the cross connecting tube 15 therebetween which carries the mud guard. For this purpose a plate 16 is secured to the outer face of the flange 11. This plate is provided with forwardly extending projections 17, at its lower edge adapted to extend under the cross tube 15, on either side of the point of connection of the mud guard to the latter. These projections 17 contact with the lower part of the cross tube 15 and as the bolts 13 pass immediately above the latter as shown in Fig. 6, any tipping movement of the forward part of the carrier is prevented as well. as upward or downward movement of the carrier along the forks.
The rear part of the platform is provided with a bracket 18, to the depending parts 19, of which are connected. the arms These arms are convenientl 1 formed from tubes with each end flattened and. apertured for connection with the parts 19 and the rear axle 5 respectively.
The platform is given its desired lateral stiffness by forming the rear cross-piece 7 of the angle-iron, one flange being secured to the ends of the tubes 6, while the other flange projects vertically downward.
I am aware that numerous details of construction may be varied through wide range without departing from the principles of this invention and l therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
I claim as invention:
1. A cycle carrier comprising in combination a platform having its forward part curved to substantially the same extent as the mud guard an angle member on the forward edge of the platform adapted to be secured to the rear fork, projections secured to said edge adapted to extend under the cross member of said fork to which the mud guard is connected, a cross piece adapted to rest against the front face of the rear fork, and means for clamping said angle member and said cross piece together to grip the rear fork therebetween, said means being adapted to extend through the fork immediately above the said cross member.
2. A cycle carrier comprising in combination a platform curved throughout its forward part to fit the mud guard of a cycle, means for securing the front end of the platform to the rear fork of the cycle and also to the cross member of said fork to whiclrthe mud guard is connected, and means for supporting the rear portion of the platform from another part of the frame of the cycle.
3. A cycle carrier comprising in combination a carrier platform, means for securing the front end of the platform to the rear fork of the cycle, a cross member between the arms of the fork, a mud guard secured thereto at its mid point, and projections on the front end of the platform extending beneath the cross member on either side of the point of connection of the mud guard to the latter.
a. it cycle carrier comprising in combination a platform comprising a plurality of longitudinal tubular members flattened at each end, transverse angle bars secured to the ends of said members, the front angle bar having one flange directed upwardly and the rear angle bar having one flange directed downwardly and means for connecting said angle bars to the frame of a cycle.
5. A cycle carrier comprising in combination a platform having its forward part curved to substantially the same extent. as the mud guard, an angle member on the forward edge of the platform, means for securing the angle member to the rear fork and to the cross member of said fork to which themud guard is secured including members projecting immediate above and below the cross member thereby positively preventing tipping or vertical movement of the front end of the platform relatively to the frame.
6. The combination with the rear forks and cross bar of a bicycle, of a platform comprising a plurality of hollow tubular members arched at their forward ends to lit the rear mud guard of a cycle, means to rigidly unite the same in spaced relation comprising a vertical flanged member having projections extending beneath said cross bar, and means extending above said cross bar and in front of said forks for securing said platform to said cycle.
In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses. V
