PARASOL ATTACHMENT FOR BICYQLES.

SPECIFICATION forming part of Letters Patent No. 617,096, dated January 3, 1899'.

Application filed January 18, 1898. Serial No. 667,075. (No model.)

To ctZZ whom it may concern:

Be it known that we, JAMES H. HARRISON and WVALLACE BROWN, citizens of the United States, residing at Lapeer, in the county of 5 Lapeer and State of Michigan, have invented a new and useful Parasol Attachment for Bicycles, of which the following is a specification.

Our invention relates to a bicycle-canopy,

lo and particularly to a device attachable to a bicycle-frame for supporting a parasol, umbrella, or equivalent device, the specific construction of the parasol forming no part of our present invention.

: 5 The objects in view are to provide a simple, strong, and efficient construction and arrangement of parts whereby the support is secured in the desired position to a bicycleframe, the parts of the support being adjust- 2o able to vary the position of the parasol without necessitating the detachment thereof.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be 2 5 particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view of the attachment applied in the operative position to a bicycle-frame. Fig. 2 is a detail view in perspective of the attachment. Fig. 3 is a detail View, inverted, of one of the clamps.

for engaging a tube of the bicycle-frame. Fig. 4 is a detail section of the connection between the bracket-arms and the socket-tube.

5 Fig. 5 is a similar view of one of the socketclamps.

Similar numerals of reference indicate corresponding parts in all the figures of the drawlugs.

0 The support embodying our invention consists, essentially, of a socket-arm 1, preferably of tubular construction and curved to arrange its upper portion parallel with and out of alinement with its lower portion, and bracket- 4 5 arms 2 and 3, provided with means for attachment to abicycle-fraine. The socket-arm is provided at its upper end, which forms a socket for the lower end of a parasol stem or handle 4, with clamping devices, consisting of rings 5, encircling the arm and having thumb-screws 6, which extend through perforations in the tube to bear terminally against the handle 4. The bracket-arms are provided at their outer extremities with frame-tube-em gaging clamps 7, corresponding in construction, each clamp having a fixed jaw '7 and a pivoted jaw 7", terminally connected by a screw-bolt S, which is fitted with a nut. The object in using the pivotal jaw in connection with the clamp is to avoid marring the bicy- 6o ole-frame in changing the adjustment of the clamps, and the pivotal jaw of the clamp is provided with an extension-ear 9, which acts as a trip to close the movable jaw as the clamp is applied to the frame.

The connection between each bracket-arm and the socket-arm consists of a-bifurcation 10 of the bracket-arm, pivotally connected with a clamp consisting, in the construction illustrated, of a ring 11, which is fitted for sliding adjustment upon the socket-arm, and a friction-block 12, through a central opening in which extends a stem or bolt 13 of the ring, said stem or bolt being fitted with a nut 14, which bears against the outer surface of the friction-block and is adapted to move said ring and block in opposite directions to firmly clamp the socket-arm. In the construction illustrated the friction-block is provided with lateral trunnions 15, upon which the bifnrcation of the bracket-arm is mounted,and by reason of this pivotal connection with the clamping device the bracket-arms may be adjusted to any desired points upon the socket-arm and have their frame-engaging clamps engaged with frame-tubes arranged at different inclinations without straining or otherwise afiecting the connection between the bracket-arms and the socket-arm. As a further means of maintaining the desired adjustment of the socket-arm with relation to the frame of the vehicle, we preferably employ an extensible construction of the upper bracket-arm 2, the construction illustrated in the drawings involving parallel relatively-movable sections 5 2 2 the former carrying a guide 16 and the latter a set-screw 17, which extends through a slot 18 in the section 2.

While in the drawings we have shown the support embodying our invention applied to the rear of the machine-frame by the engagement of the clamps with the seat-post tube, it will be understood that by reason of the peculiar construction and relative arrangement of the parts the same can be applied to the head-tube, the latter arrangement being preferable when the device is applied to a diamond-frame or other wheel designed for male use.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention. 7

Having described our invention, what we claim isl. A canopy-support for bicycles having a socket-arm, a plurality of bracket-arms having terminal clamps for engaging a frametube, the bracket arms projecting rigidly from said clamps, and one of them being of extensible construction and provided with means for securing its members at the desired adjustment, and socket-arm clamps mounted for vertical adjustment upon the socket-arm and pivotally mounted upon the bracketarms, substantially as specified.

2. A canopy-support for bicycles having a socket-arm, terminally-bifurcated arms pro vided with means for engagement with a bicycle-frame tube, and clamps having rings fitted to slide upon the socket-arm and pro vided with stems, friction-blocks for contact with the socket-arm, and means for impartin g motion in opposite directions to said rings and friction-blocks, the bifurcations of the bracket-arms being pivotally mounted upon said clamps, substantially as specified.

3. A canopy-support for bicycles having a socket-arm, bracket-arms having terminal bifurcations and provided with means for engagement with a bicycle-frame tube, and clamps consisting of rings fitted to slide upon the socket arm and provided with stems, friction-blocks mounted upon said stems for frictional engagement with the socket-arm, and provided with lateral trunnions upon which the bifurcations of the bracket-arms are mounted, and nuts threaded upon the stems of said rings, substantially as specified.

In testimony that we claim the foregoing as our own We have hereto affixed our signatures in the presence of two witnesses.
