BICYCLE-LAMP SUPPORT.

SPECIFICATION forming part of Letters Patent No. 842,906, dated February 6, 1900.

Application filed July 31, 1899. $erial No. 725.64% (No model.)

To t whont it may concern.-

Be it known that I, FREDERICK W. HEDGE- LAND, a citizen 0F the United States, residing Illinois, have invented certain new and useful Improvements-in LaInpBracketAttach merits; and I do hereby declare the followingto be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to an attachment for the support and adjustment of lamps on bicycles, and has for its object to provide a device of this character that will permit of the lamp being taken off and replaced without changing the angle of inclination or reflection.

. Under the ordinary arrangement each time that a bicycle-lamp is replaced after having been removed for cleaning or other purposes it must be readjusted to the required angle in reflecting the light in the proper direction,

often the cause of a good deal of annoyance.

The-present invention provides a simple and convenient devicethat may be set to support the lamp at the proper angles and then The lamp may then be removed and replaced as many times as necessary, but 'will alwaysremain at the same-angle without requiring any attention to thead- In the accompanying drawings, Figure 1 is a broken-away elevation of the front frametube, showing a lamp in position. Fig. 2 is a plan of the attachment and connecting parts. Fig. 3 is a broken-away section on line 3, Fig. 2, looking in the direction indicated by the arrow. Fig. 4 is a section on line 4:, Fig. 2. Fig. 5 is a detached view in perspective of the supporting-lug, showing recess for the reception in perspective of a washer, showing the aper-.

A may represent the front frame-tube of a. bicycle, B theusual lamp-bracket-holding ring, and C a lamp. A'lug D is secured to the lamp-bracket ring, as at a. This lug is provided with an annular recess'a, in which is loosely seated a revoluble disk E, as shown in Figs. 3 and 4'. A locking and clamping bolt F is inserted through the lug D and the disk E from one side and projects far enough from the opposite side to receive the threaded wing-nut o The aperture a in. the lug is not threaded, but the aperture of in disk E is threaded, so that the locking-bolt has a threaded engagement with the disk, but not with the lug, as is necessary in the operation of the device.

The disk E is provided on its outer side I with an integral raised guide-plate b, which is formed by thickening the disk at that point, asshown in Figs. 3 and 4.

The supporting-arm (Z of the lamp vided with a slot cl, starting in from the edge at one side, as shown in Figs. 1 and4. When the lamp is attached, the S1 in the supporting-arm straddles the locking-bolt and engages the respective sides of the guide-plate b and holds the lamp firmly in place and at an angle in accordance with the relative position to the stationary'parts of the plate on the disk E. All the parts are shown in their locked and clamped position in Fig. 4.. The lamp is clamped in plae by'the wing nut a is pro-. 1

a washer 9 being inserted between the same 7 and the slotted arm of the lamp.

"By slacking back on. the bolt F from the locking position illustrated in Fig. 4 the disk may be turned so as to bring the plate into any desired position with reference to the Then tighten up the bolt, which has the effect of locking the disk in the position to which it has been adjusted. This feature of getting the angle at which'the lamp is to be carried is independent from the means employed to removabl y clamp the lamp in place. The lampis taken off byturning back on the wingnut, which relaxes the clamping pressure on the slotted arm. This is done without disturbing tho 1 'ition of the disk E or its locking-bolt; so tll t when the lamp is replaced it will be held at the same angle, thus obviating the labor and annoyance attending the adj ustangle at which thelamp is to be supported. 1.

ing ofthe lamp to the desired angle each time it is taken otf. This construction and arrangement forms a combination device, both features of which, that of locking the angleadjusting mechanism and the means for reinovably clamping the lamp in place,being united in the same structure, yet having an independent action from each other, both oplegrations being controlled by one and the same This devicemaybe used on different kinds of vehicles other than bicycles and also for stationary lamps. V

The device as illustrated is in position for supporting the lamp'on the right-hand side. It may be converted into a left-hand attachment by turning the bracket-ring upside down from the position shown and then turning the-revoluble disk E to bring'the guideplate thereon into position to receive the slotted end of the lamp-arm in supporting the lamp at the desired angle of inclination. 0

Having thus described my invention, what I claim as new, add desire tosecune by Letters Patent, isi 1. In a lamp-bracket, the'combination with 'a lamp, of an angle-adjusting means, and a bolt or clamping device for effecting such adjustment, said bolt also mounting the lamp in position and permitting of its being removed and replaced without disturbing the angle at which it is supported, substantially as described.

2. In a lamp-bracket, the combination with a supporting-lug, of angle-adjusting means embraced 'therein, said lug forming the lam psupport and permitting of the removal ofthe 3olamp therefrom without disturbing the angle adjustment, substantially asdescribed.

3. In a lamp-bracket, the combination with a bracket-ring, provided with a lug, of a revolnble disk, provided with-a guide-plate and loosely recessed in said lug, and a locking- A bolt, inserted through the lugand having a threaded engagement with said disk, where by the latter may be turned to bring the guideplate into position to support an object at any 40 desired angleand then locked in place, sub stantially as described.

4. In a lamp-bracket, the combination with nutfor clam ping said lamp-arm, substantially 5o as described. f

In testimony whereof I aflix nay-signature in presence of tvro witnesses.
