LAMP-MOUNTING.

T0 all whom it may concern Be it known that I, ELLswoRTH A. Haw- 'rrioRNn a citizen of the United States, and a resident of Bridgeport, county of Faireld, and State of Connecticut, have invented an Improvement in Lamp-Mountings, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to lamp mountings, and more especially to a universally adjustable mounting, or bracket, for supporting a lamp upon the steering structure of a cycle.

My invention will be best understood by reference to the following speciiication, when taken in connection with the accompanying drawings of several specific embodiments thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings: Figure 1 is a plan of one form of lamp mounting embodying my invention; Fig. 2 is a side elevation of the same; Fig. 3 is a front elevation of the samej Fig. 4 is an enlarged detail side elevation, partly in section, of a modication in which the lamp mounting is secured to the handle bar only; Fig. 5 is an elevation of the parts shown in Fig. 4, viewed from the right side; Fig. 6 is a side elevation of another form of mounting, in which an acetylene gas generator for the lamp is also mounted on the lamp mounting; Fig. 7 is a side elevation of the mounting' shown in Fig. 6, as adapted for a battery to supply current to an electric lamp mounted on the mounting; Fig. 8 is a side elevation of still another mounting adapted for an acetylene gas tank at the rear of the lamp; Fig. 9 is a side elevation of the mounting shown in Fig. 8, adapted to support the battery for supplying current to the lamp; and Fig. l0 is a side elevation of another form of lamp mounting embodying my invention, in which the brace rods eX- tend from the lamp supporting arms downwardly to the front axle of the cycle.

Referring to the drawings, and more especially to Figs. 1, 2 and 3, 11 is a lamp, which may be of any suitable type, which it is desired to support on the steering structure of a cycle. The latter comprises a fixed head 12, and a swiveled steering head 13, having a usual handle bar 14 and a pair Specification of Letters Patent.

Application filed March 24, 1913.

Patented Mar. 24, 1914. serial No. 756,492.

of fork braces 15-15 of common form, which serve in the case of a motor cycle to brace the front fork. These fork braces are usually inclined forwardly and downwardly from their point of attachment to the steering head, and in some cases diverge downwardly, while in other cases, they are parallel.

In the construction shown in Figs. 1, 2

l and 8, the fork braces 15-15 serve as supports for a pair of lamp-supporting arms 16-16, the latter being provided with vertical studs 17-17 passing upwardly through and secured to lugs 18-18 of the lamp, by means of nuts 19*19. In order to provide for the angular adjustment of the lamp in a vertical plane, as well as to provide for an adjustment of its mounting t0 suit supports of different dimensions, the lamp supporting arms 16 are mounted on the supports 15 by suitable universal connections and suitable clamps. Any other suitably adjustable connections may be provided, but herein each of the arms 16 is mounted on a pivot 20 on substantially horizontal axes A-A, so as to permit the lamp to be angularly adjusted in a vertical plane. The pivots 20, in turn, are mounted on swivel members 21, which latter are swiveled on pairs of suitable clamps 22 secured to the supports 15. Each pivot 2O may be in form of a bolt passing through the arm 16, and swivel member 21, and if desired, t-he latter may be provided with suitable means interengaging with the arm to lock the latter in the desired position of adjustment. Such locking means may be in the form of two sets of interengaging teeth 23 and 24 (see Fig. 3), which may be disengaged by simply loosening the bolt, then adjusted to the proper angle, and afterward locked in the new position of adjustment by tightening up the bolt in an obvious manner. The swivel members 21 are mounted on the clamps 22 to turn about axes B-B, preferably .at right angles to the axes rfi- A of the pivots 20. By this means, the arms 16 may be adjusted not only about the axes A-A of the pivots 20, but also about the axes B-B of the swivels 21. Ars a means for securing the swivels 21 to the clamps 22 and securing the latter to the supports 15, the swivels may be provided with screw-threaded Shanks 25 passing through the clamps, and provided with nuts 26.

Each of the clamps 22 is herein composed` of two

clainp members

27 and 28, the latter being provided with one or more slots 29 adapted to receive tongues 30 provided on the clamping members 27, respectively. By

this means, the clamp 22 may be adjusted to lit the supports 15 of various diameters within their range of adjustment, and said clamps may be adjusted about the axes C-C of said supports. As a further means for securing the lamp supporting arms 1G in the selected position of adjustment, and bracing said arms to prevent the lamp from vibrating, I may employ braces extending from said arms to some suitable part of the supporting structure. In the form shown in Figs. 1, 2 and 3, I have shown a pair of braces 31 extending from the forward end of the lamp supporting arms 16' to the handle bar 14. As a means for securing each of the braces 31 to its respective lamp supporting arm 16, a clamping collar 32 encircling the forward end of such arm is provided with a pair of ears 33 embracing the forward end of the brace rod, and provided with a clamping screw 34, which latter also serves as a pivot about which the brace rod may be swung in a vertical plane. It will now be understood that the brace rods 31 may be adjusted about the vertical axes D-D of the forward ends of the lamp supporting arms, and about the horizontal axes E-E of the pivots 34. It will be evident, also, that the lamp supporting arms may be adjusted about the axes D-D, by swiveling the studs 17 in the lugs 18.

The rear ends of the brace rods 31 are herein secured to the handle bar 14, by means of clamps 35 encircling and clamping about the latter, each of these clamps in the present instance comprising two

clamp members

36 and 37 provided respectively with

ears

38 and 39. Each brace rod, where it passes through the

ears

38 and 39 of its respective clamp, is screw-threaded and provided with clamping nuts 40 and 41, which may serve the double purpose of contracting the clamp and adjusting the brace rod longitudinally. Since handle bars vary somewhat in diameter, the clamps 35 are preferably provided with means permitting a considerable range of adjustment. In the present instance, the clamp member 37 is provided with a plurality of slots 42, either of which is adapted to receive a tongue 43 provided on the clamp member 36. The nuts 40 and 41 obviously serve as an additional means of adjustment, as well as serving to contract the clamps about the handle bar 14 to secure them rigidly in place. It will now be evident that since the clamps 35 are swiveled on the handle bar 14, they provide a means for permitting adjustment of the brace rods 31 about axes F-F, while the brace rods are being adjusted about axes E-E. If desired, the brace rods'31 may be made longitudinally adjustable or extensible, by means of sleeve nuts or turnbuckles 44, interposed between, and having right and left screw-threaded engagement with, the .front and rear parts of the brace rods.

If desired, the lamp mounting may also serve as a mounting for the number-plate required by law in some States to be car-v ried on the front part ofthe machine. This may be accomplished very conveniently by providing a pair of uprights 45, having their lower terminal portions bent Vto conform to the shape of the clamp member 37, and pro-vided withsuitable perforations to receive the brace rods 31, while theY nuts 41 serve to vrigidly clamp the uprights in place, thereby forming an eifective and attractive means for supporting a number-plate 4G secured to the uprights.

porting arms upon the handle bar of the In some cases, it. may be desirable tosupport the lamp-supcycle, as shown in Figs.`4.and 5. In such Y casc, no changes inthe construction of the mounting hereinbefore described will be necessary, except the'omission ofthe brace rods, which in the described construction extend from the handle bar to the forward ends of the lamp-supporting arms. In the construction shown in Figs. 4v and 5, however, I have shown a slight modication of the clamp for securing the swivels to the handle bar. In this form, the clamp comprises two

clamp members

47 and 48, which instead of being provided respectively with interlocking tongues and slots, as in the already describedv form, are provided with

ears

49 and 50 to receive the clamping bolt 51. In other respects, the mounting is ex-v actly similar to that illustrated in Figs. 1, 2 and 3. l

If desired, the lamp mounting may also serve as a convenient mounting for an appropriate lamp supply means, as illustrated in Figs. 6, 7 8 and 9. In 'cases where an acetylene gas lamp is employed in connection with the generator, the latter may be conveniently supported at the rear of the lamp upon the lamp mounting, as illustrated in Fig. 6. This may be accomplished by simply 'dispensing with the described turnbuckles or sleeve nuts 44, and mounting a gas generator 52 on the brace rods by means of appropriate clamps 53. If an electriclamp is employed, the brace rods 31 may serve as a support for a lamp supply means in vthe form of a suitable battery, or b-atteries, mounted in ajcase 54, supported on` the brace rods, as shown in Fig. 7, directly at the rear of the lam-p.

In case it is desired to employ a gas storage tank to supply the lamp, I inaysubstitute for the brace rods 31 a pair of brace rods 55, as shown in Fig. 8, appropriately lformed to receive the tank, the latter being securely held in place by means of suitable straps 56, partially encircling the tank, and secured to the brace rods by bolts 57. In other respects, the lamp mounting may be exactly similar to that already described, and shown in Figs. l, 2 and 3. By simply omitting the straps 56, the bolts 57 may serve as a convenient means for mounting a battery, or battery box 5S on the brace rods 55, as illustrated in Fig. 9, without requiring other change in the construction of the mounting. By supporting the lamp supply means upon the lamp mounting in any of the described ways, a short direct connection with the lamp can be made, and the use of long, inconvenient, flexible connections may be avoided, thus obviating the objection .which has heretofore existed, where the lam-p supply means was located on the main frame of the cycle. By placing the lamp supply section directly upon the lamp mounting', moreover, it is out of the way of the rider, and: may be easily controlled by providing a controlling valve or switch, as the case may be, adjacent the handle bar, so that the lamp may be conveniently regulated.

Referring now to Fig. 10, this form of my invention is similar in all respects to that shown and described in connection with Figs. 1, 2 and 3, with the exception t-hat I have substituted for the brace rods 3l and their connections a pair of brace rods 59, extending from the lamp supporting arms to the axle 60 of the cycle, the lower terminal portions of these brace rods being provided for this purpose with ears 61, through which the usual axle 60 extends. If desired, these brace rods may be made longitudinally adjustable or extensible, by means of sleeve nuts or turnbuclrles 62 having screw-threaded engagement with upper and lower sections of the brace rods, as clearly shown in Fig. l0. By this means, lthe angle of inclination of the lamp may be readily adjustable, and the lamp rigidly held in fixed position while in use.

IVhile I have herein shown and described several embodiments of my invention for illustrative purposes, and have discussed and disclosed in detail the construction and arrangement incidental to several applications thereof, it is to be understood that the invention is limited neither to the mere details nor relative arrangement of parts, nor to its specific embodiments herein shown, but that extensive deviations from the illustrated forms or embodiments of the invention may bc made without departing from the principles thereof.
