2 Claims.

This invention relates tobobs for fish lines and has as its object the provision of a bob equipped with means whereby the bob will be automatically illuminated.

A still further object of the invention is to provide a bob designed to fulfill all the requirements of night fishing.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure l is a side elevational view of the bob.

Figures 2, 3 and 6 are sectional views taken substantially on the lines 2-2, 3-3 and 66 respectively of Figure 1.

Figure 4 is an enlarged sectional view through the bob and Figure 5 is an enlarged fragmentary sectional view showing the means of securing the line accommodating tube to the body of the bob.

Referring to the drawings by reference numerals it will be seen that the bob comprises a cylindrical body 5 of any suitable light and durable material. Screwed on to the ends of the body 5 arehollow substantially, dome- shaped caps 6 and 7 respectively. The cap 6 is provided with a threaded neck 8 forming a socket for the threaded reception of the stem of a conventional electric bulb 9. The cap '7 is provided with an opening through which ballast material may be introduced into the cap '7, and for this opening there is provided a suitable plug 10. Disposed across the cap '7 adjacent the threaded end thereof is a disk or partition 11 secured in place by solder or as found desirable and as indicated generally at 12.

Threaded in the end of the body 5 opposite to the cap 7 is a plug 13 of insulation material and of disk form. Thus the partition 11 and disk 13 provides for positively closing the ends of the body 5, and clamped between the end of the body 5 and the cap '7 is a gasket 14 that provides a watertight joint between said body and cap.

Arranged within the body 5 is a' suitable battery 15 and the same is secured in position through the medium of any suitable spaced supporting brackets 16. Preferably the brackets are of the two-part clamp type shown in Figure 3, and are of such a construction as to support the battery 15 substantially centered within the body 5.

Supported by the partition 13 is a contact stem 17 that has an end thereof extending through an opening in the partition 13, and at said end is provided with a head 17a that is engaged with the contact of the battery 15 as shown in Figure 4. At its bottom end the battery 15 is grounded through the partition 11 by a spring 18 of conductive material.

Operating within the cap 6 is a float 19 of cork or other suitable material and extending through the center of the cork 19 is a metallic sleeve 20 of conductive material, which sleeve it will be noted is in intimate sliding contact at one end with the contact member 1'7, and at a relatively opposite end is provided with a head 20a adapted to be moved into engagement with the contact on the stem of the bulb 9 for completing the circuit through the bulb. In this connection it will be noted that the cap 6 is provided with a series of openings 21 for the admission and egress of water. It will thus be apparent that by reason of the water entering the cap 6 through the apertures 21 the float 19 will be caused to raise upwardly (see Figure 4) causing the head 20a of the contact sleeve 20 to engage the contact of the bulb 9 and thereby complete the circuit to the bulb for illuminating the bob. The passage of water into the cap 6 will take place when the bob is drawn under the surface of the water by the pull of the fish on the line as is thought apparent.

For attaching the bob to the fish line 22 there is provided an elongated tube 23 through which the line 22 is passed, and the line is provided with knots or otherwise as indicated at 24 to engage the ends of the tube 23 in a manner to hold the bob at the desired position in the length of the line. The tube 23 is secured to the body 5 of the bob through the medium of sleeves or collars 25 that are in turn secured to the body 5 in any suitable manner.

Having thus described my invention, what I claim as new is:

1. A fish bob comprising a hollow body having at one end a float chamber, and a socket, an electric light bulb arranged in the socket and having its stem extending into said float chamber,

a battery confined within the bob, a fixed con- 4 tact member having an end in electrical engagement with the battery, a float arranged in the float chamber, and a sleeve extending through the float having sliding electrical contact with said fixed contact, and also having an end adapted to move into electrical engagement with the contact of the light bulb for completing the circuit through the bulb, said float chamber being provided with openings for the ingress and egress of water.

2. A bob for fish line comprising a hollow body having a plug in one end, a battery arranged within the body, a fixed contact member extending through the plug and having an end in electrical contact with the battery, a hollow cap for the plug equipped end of the body, said cap being provided with a lamp socket, a lamp engaged in the socket, a float arranged in the cap and having a bridging contact in sliding engagement with the first named contact and adapted to engage the contact of the lamp for comp1eting the circuit through the lamp, said cap being pro vided with apertures for the circulation of water therethrough.
