AUTOMATIC CHAIN-CLEANING DEVICE FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 602,000, dated April 5, 1 898. Application filed November 5, 1896. $erial No. 611,181. (No model.)

To aZZ whom it may concern..-

Be it known that I, EUGENE FAY, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Automatic Chain- Oleaning Devices for Bicycles; and I do declare the following to be a full, clear, and exact description of the invent-ion,such as will en able others skilled in the art to which it ap pertains to make and use the same, reference being had to the accompanying drawings, and

to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements for keeping the chains of bicycles clean during use.

My improved device is adapted to be attached to the frame of the bicycle and may be made to engage either the upper or lower part of the chain, preferably the latter, as shown in the drawings.

The device consists of a stem, to which are attached two shoes adapted to receive blocks carrying brushes. I

The device is so located that the two brushes engage the chain on opposite sides. One of these brushes is fast and the otherven tically adjustable on the stem. To this stem is secured a clamp adapted to' surround one of the lower frame-bars of the machine.

The device will now be described in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation of a bicycle equipped with my improvements. Figs. 2 and 3 are detail views.

Similar reference characters indicating corresponding parts in the views, let the numeral 5 designate a stem having a clamp 6, secured by means of nuts 7, screwed on the threaded extremity of the stem, one nut engaging the clamp on each side. Below the clamp and applied to the threaded portion of the stem is a shoe 8, having flanges 8*, bent to form a dovetailed receptacle in which is located a block 9, carrying a brush 10. The shoe 8 is provided with a projection 8 through which the stem 5 passes. The shoe is secured in place by means of nuts 7, applied to each surface of the projection 8. To the opposite extremity of the stem is attached another shoe 8 of the same construction as thatalready described. This last-named shoe is made fast to the stem, and its brush projects toward the brush of the opposite shoe.

When the device is in use, the clamp is applied to the frame-bar 12 of the bicycle, the clamp being adjusted on the stem to bring the lower brush in contact with the lower surface of the chain 20. The opposite brush is then so adj usted. on the stem as to cause it to engage the upper surface of the chain. Hence when the bicycle is in use the lower part of the chain runs' between and in contact with the two brushes.

The brush-blocks 9 are preferably composed of wood. They are forced tightly into the shoes. When abrush is worn out or becomes useless, the block is removed from the shoe and another block with a new brush put in its place. As the brushes become worn they may be kept in contact with the shoe by the adjustment of the clamp and one of the shoes.

Having thus described my invention, what I claim is As an improved article of manufacture, a chain-cleaning device for bicycles comprising a vertical stem having its upper extremity threaded, a clamp attached to the upper extremity of the stem, a horizontal shoe or holder whose body part is composed of flanges bent to form an open-ended, dovetailed receptacle, said shoe having a projection apertured to re ceive the threaded portion of the stem, locknuts applied to the stem and engaging the apertured projection of the shoe on opposite surfaces, whereby the said shoe is vertically adjustable on the stem, a block inserted in the dovetailed receptacle of the shoe and having a depending brush, said block being detachable, a similar shoe made fast to the lower extremity of the stem, a detachable block inserted in said shoe and provided with an upwardly-projectin g brush, the two brushes being adapted to engage the opposite surfaces of the chain when the device is in place on the bicycle, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

. EUGENE FAY.
