LAMP-SUPPORTING BRACKET.

SPECIFICATION forming part of Letters Patent No. 764,111, dated July 5, 1904. Application filed March a, 1904. Serial No. 196,386. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK CLARK, a citizen of the United States, residing at Clearlake, in the county of Sherburne and State of Minnesota, have invented certain new and useful Improvements in Lamp-Supporting Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention has for its object to provide a simple and eflicient lamp-supporting bracket adapted for use to support a lamp or bulls-eye from the end of a wagon or carriage pole or from the end of one of a pair of thills.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a view in side elevation showing a bulls-eye lamp supported from the end of a pole by means of one of my improved brackets. Fig. 2 is a detail in side elevation showing the improved bracket removed from working position and showing also the lamplug to which it is to be attached, said lug being broken from the lamp-body. Fig. 3 is a detail in front elevation of the bracket shown in Fig. 2. Fig. 4 is a similar view to Fig. 1, but shows the bracket turned upward to support the lamp in an elevated position; and Fig. 5 is a plan view showing a pair of thills and showing the bulls-eye lamp supported therefrom by a bracket of slightly-modified form.

The numeral 1 indicates a pole, and the numeral 2 a pair of thills.

The numeral 3 indicates a bulls-eye lamp of standard construction, the same having at its rear side a projecting lug 4:, which lug is preferably slotted at 5 and provided with annularly-disposed corrugations 6.

The bracket shown in Figs. 1 to 4:, inclusively, is in the form of an arm 7, having at its base end a split and slightly-tapered clamping sleeve or hub that is. adapted to fit onto the end of the pole. The free edges of this clamping collar or hub 8 are formed with projecting webs 9, that are perforated to pass therethrough a screw 10. One end of a clamping-lever 11 works with screw-threaded engagement on the projecting end of the screw 10. At its free end the arm 7 is bent laterally and forwardly at 12, and it is terminated in prongs 13, that are perforated to pass therethrough a screw 14. The thumb nut 15 works on the projecting threaded end of the screw 14:.

When the thumb-nut 15 is loosened, the lamp-lug 4 may be placed between the jaws 13, with its slot 5 straddling the screw l t, and when the said thumb-nut is tightened the lamp may be supported in any set position and at any desired angle with respect to the ground. The clamping-sleeve 3 may, as is evident, be very rigidly clamped to the pole by turning the clampinglever 11 on the screw 10, so as to draw the webs 9 toward each other. The offset or bent end 12 of the arm 7 permits the lamp to be set in an upright position when the arm? is turned downward, as shown in Fig. 1. Furthermore, by turning the said end of the arm into an approximately horizontal direction it is made easy to apply and remove the lamp-lug 4. to and from Working position between the jaws 13.

Fig. 1, as already indicated, shows how the lamp may be supported in an elevated position above thepole. There are times when it is desirable thus to support the lamp in an elevated position, and there are other times when it is desirable to support the lamp in a position below the pole. As is evident, these changes of position may be easily and quickly accomplished with the device described.

The lamp-supporting bracket illustrated in Fig. 5 is substantially like that above described, except that it is smaller and that its bent end 12 has its jaws 13 located at approximately a right angle to the webs 9 of the clamping-sleeve 8. construction is made desirable because the arm 7 is intended to be located in a horizontal position, whereas in the construction previously described the said arm was intended to stand in a vertical position.

This latter variation in 9 The device described, while extremely simple, convenient, and eflicient in all Ways for the purposes had in view, is of small cost. lts practicability has been thoroughly demonstrated by actual usage.

hat 1 claim, and desire to secure by Letters Patent of the United States, is as follows:

The combination with a lamp having the projecting lug 4;, of the arm 7 formed at one end with the split-spring clamping-sleeve 8, having webs 9, the free end of said arm being bent laterally at 12 and pronged at 13, said prongs adapted to receive between them the said lug 4:, a screw device applied to said prongs 13 to clamp them onto said lug 4, and 5 a screw device, including a lever 11, applied to said webs 9 and serving to draw said clamping-sleeve onto the pole or thill, substantially as described.

In testimony whereof I afiix my signature in 20 presence of two witnesses.

FREDERICK CLARK.
