BICYCLE-SUPPORT.

i SPEQIFIGATJLON forming part of Letters Patent No. 669,538, dated March 12, 1901.

Application filed April 28. 1900 To (tZZ whom it may concern:

Be it known that I, EBEN MILLER, a subject of the Queen of Great Britain, and a resident of Fredericton, in the county of York and Province of New Brunswick, Dominion of Canada, have invented a new and Improved Bicycle-Support, of which the following is a full, clear, and exact description.

This invention relates to improvementsin devices for supporting or holding bicycles in a vertical position when not in use; and the object is to providefa supporting device of simple construction that may be quickly adjusted to either of its positions and having a means to hold the front wheel from rotary and lateral or swinging motion.

1 will describe a bicyclesupport embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi cate corresponding parts in all the figures.

Figure 1 is a side view of a bicycle, showing a supporting device embodying my invention as applied thereto. Fig. 2 is a side view of the device, and Fig. 3 is a frontview thereof.

The device comprises a supporting-frame consisting of an angle-iron having a vertical portion 1 and a rearwardly-extended portion 2. The ends of these portions are rigidly attached to the bottom brace 3 of the bicycleframe. The two connecting devices for the ends of this frame are similarin construction, and one of them, as shown clearly in Figs. 2 and 3, has a fastening device consisting of a flexible strap 4, engaging around the bracebar, and arranged within this strap are two clamping-blocks 5 and 6. The clamping-block 5 has its upper edge concaved to receive the brace-bar, while the lower edge of the block 6 is conformed to the shape of the strap 4, as clearly indicated in Fig. 3.

The upper end of the vertical portion 1 of the frame is turned forward and upward and inserted in an opening in the block 6, and it is held rigidly in connection with the block 6 by means of a set-screw 7, passing through the strap 4 and through a tapped hole in the block 6 and engaging with the frame. When it is desired to tighten the frame on the brace- Serial No. 14,712. \No model.)

bar, wedges S are driven between the two clamping-blocks 5 and 6, thus spreading the blocks apart and causing the strap 4 to engage tightly with the hiflOQlOd.

Movable on the vertical portion 1 of the frame is a rack-bar 9, having racks 10 11 on its opposite sides, there being a space 12 between the two racks. Gear-wheels 13 and 14 engage, respectively, with the racks 10 and 11. These gear-wheels are mounted to rotate on studs attached to a bracket 15, secured by means of a bolt 16 to the lower portion of the upright l of the frame. The bolt 16 passes through the slot or opening 12 and engages with a plate 17, which connects with two lugs forward of the gear-wheels 13 and 14. At the upper portion the rack-bar has a rearwardly-extended lug 18, provided with an opening through which the vertical member of the frame passes, and extended upward from the rear end of this log 18 are straps 19, which at their upper ends connect with a slide or loop 20, designed to slide on the vertical portion 1 of the frame. Pivoted between the straps 19 is a lever 21, designed to engage its head portion with a spring 22, attached at its lower end to the lug 18 and adapted to bear friction-tight at its upper end against the rear side of the vertical portion 1 of the supporting-frame.

Extended outward from the upper portion of the frame-section 1 are plates 23, in which a roller 24 has a rocking motion, and extended outward from the lower end of the rack-bar are plates 25, in which a roller 26 has a rocking motion. Plate-springs 27 and 28 connect at their upper ends with the outer ends of the shaft 24, and at their lower ends they connect with the shaft 26. Supporting-legs 29 30 are connected, respectively, to the gear-wheels 13 and 14. I have here shown them as having their ends engaged in sockets 31, which are rigidly attached to the wheels. The space between the springplates 27 and 28 is substantially equal to the cross-section of the wheel-tire, so that they may engage with the opposite sides thereof.

In operation when the device is in supporting position the ends of the legs 29 and 30 will. engage with the ground in a divergent manner, as indicated in Fig. 1, and at this time the spring-plates 27 and 28 will be forced outward to engage against the sides of the front-wheel tire, as also indicated in Fig. 1, forming a brake to prevent a rotary movement of the wheel and also forming stops to prevent lateral or swinging movement thereof. Thus the wheel will be held rigidly in a vertical position.

Upon drawing the lever 21 outward to the position indicated in dotted lines in Fig. 2 the pressure of the spring 22 on the frame will be relieved, so that the rack-bar may be moved downward, imparting a rotary motion to the gear-wheels 13 and 14, which will swing the supporting-legs upward to the position indicated in dotted lines in Fig. 1. This downward movement of the rack-bar by moving the spring-plates 27 28 to cause them to approach the rack-bar will disengage thein from the tire of the wheel. The spring-plates 27 and 28 not only serve for the purposes above described,'but when in their retracted position they will also serve as mud-guards.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. Abicycle-s11pport,comprisingasupporting-frame, a rack-bar movable on said frame, gear-wheels for engaging with the rack-bar, supporting-legs carried by the gear-wheels, and a wheel-engaging device operated by movemen ts of the legs, substantially as specified.

2. A bicycle-support,comprising a supporting-frame, a rack-bar movable on said frame and having two racks, gear-wheels engaging with said racks, supporting-legs carried by the gear-wheels and a wheel-engaging device operated by movements of the legs, substantially as specified.

3. A bicycle-support, comprising a frame adapted to be secured to a bicycle-frame, a rack-bar adjustable on said frame, means for locking the rack-bar as adjusted, two racks on said bar, gear-wheels engaging with the racks, supporting-legs carried by the gearwheels, and spring-plates supported at the upper end by the frame and at the lower end by the rack-bar, the said plates being adapted to move into engagement with the front wheel of the bicycle when the supporting-legs are moved to their lower position, substantially as specified. v

4. In a bicycle-s11 pport, a frame consisting of an angle-bar, clampingdevices for said angle-bar, consisting of straps for engaging around a bar of the bicycle-frame, clampingblocks arranged in said strap, means for moving said blocks away from each other, the ends of the supporting-frame being removably secured to the lower clamping-blocks of the clamping devices, and supporting-legs adjustable on the supporting-frame, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EBEN MILLER.
