Taal/wimmelt may concern-1 Be it known that* I, EUGENE GEORGE Ummm-NAT, citizen of France, re'sifdmg'g` at Birmingham, England?, have' inventeol` cerl tain new and' useful Improvements ill Means for Supporting Lamps, offWhic-h the* follow'- ing is a specification. Y

This inventibn relates toy lamp brackets for use on motor ,cars and other vehicles, motorlcyoles anfd" the like:

' Th'eobject of the pi'fesent invent-ion' is to enable a standardized forni of'bia'cket te bet readily applied? t-o any type' of vehicle' or machine, while also' adrijdt-'ting4 of adjust'- ment or the lampinl botl'i a horizontal and a' vertical plane. ,y

According tio the invention the; bracket' is hinged" or'jointe'd (so as to'beadjustable in a verticalv plane) to a pillaror' post Whichv .is adaptedto' t intoa socketcarri'ed bythe vehicle ort'helike andto'beadju'stably fiXe'dv therein, With the lamp in any desiredV po'- sition inthe horizontal plane, by means of a clip or other suitable' fasteningV device'.

Figure l of the accompanying" drawings is a side elevation' showing'tlie improved' means for carrying= anl electric ni'otorfcar lamp.

F ig. 2 is a vertical section showingV the' upper portion of thel bracket" adjusted' relatively tothe lowerportio'n.

Fig. 6 shows;` a li-orizo'ritalf4 section'y through the socket and stem, on line x3, rFig. l.

Fig; 7 representsthe various componentJ parts of the fitting separatelydn'f frontend side elevation and partiyfili 'sectin F ig. 8 shows a modification "ofthe" means for locking the knuckle joint.

Referring to Figs. l to 7 the bracket consists of a vertical stem 1, attached at its upper end to the lamp body 2 in the manner hereinafter described, and provided at its lower end with a lug or tongue 3 which engages between the vertical jaws o1 cheeks of a fork 4 carried at the summit of a pillar 5 adapted to enter a socket 6 attached to a suitable part of the vehicle. A screw-pin or bolt 7 fitted With a clamping nut 8 and spring washer 9 is passed transversel)r through the fork and lug s0 as to form a knuckle joint, permitting of the adjustment ot." the lamp inV al Vertical plane, the lampbeing adapted to be iXed in any adjusted position by tightening uptli'e clampingnut'. To insure the joint being more securelyl lecked, however, tivo Washe'ralO, l0, serlatedv on both faces, arey placed recesses 1l, l1, inA opposite faces off the knuckle tongue member 3 so as to engage'V with' thfe plain inner, faces of the of the'V fork" n'ieinber; Thesej 'aref also e'kten'dedvreai'e War'dly into lugs 1'2'Wh'ich are'lpier'ce'd With internally' toothedl holesrt'ov receive a transverse cotter'pin 13 provided xv'ith ln'gitudi'- nail' te'etli adapted to engage with teeth/or serrations lformed around the circular pe'- rphery ofthe inner'ortongue member?) of the knuckle, thus constituting a positive lock'. The cott'er 13 is'fttedi with a nut' 14 at one end- The pillar or post 5 has a stop shoulder l5 at its upper end,an d` below7 this shoulder it' provided With` longitudinal se'rrations. The socket' (3 consists' of a split tube provided at its upper end with lugs 16', onop' ,'osite sides of the slit, tted with a boltv l and' nut 18' with spring'ivasher I9. The mouth of the socketv isy of slightly smaller internal diameter ythan the lower part, and is formed around itsinterior With vertical serration's 20'correspon'dingj to, and adapted to be en'- gagedby, theserratiois of the pillar 5, By tightening up the bolty 17' the serrated part ofthe socket can be contracted" around the pillarso as to hold the latter in position and' positively prevent'rotati'on'there'of. rais# in'gor low'veringthe pillar the height o tth'eL lampcan be adjusted, and by partially" 'rotatingit in the socket (the bolt'lbeig- 's'llackened) the' angle in;y the' horizontal yplan'feat which the light is projected" can likewise be adjusted.

The upper part2l of the bracket stem is externally screw-threaded and is of D-section, or other non-circular section, being adapted to be passed through a correspondingly shaped hole in a socket member 22 attached to the underside of the lamp. .The socket member 22 has a reduced portion which is externally screvv-threaded -and is adapted to be engaged by a union-nut 23 sivivelly attached to the stem by means of an internal flange of the nut 23 engaging beneath a collar 24: secured to the stem. The union-nut 23 can be fixed by means of a stem 1 are drilled aXially at 28, 29, re-

spectively, and upon opposite sides of the knuckle joint are drilled with

lateral holes

30, 31, leading into the axial holes, the conductor being passed, as shown, up the pillar 5, through the lateral hole 30 near the top so as to bridge the joint, and through the lateral'hole 31 at the bottom of the stem l and thus up the aXial hole 29 of the said stem to the lamp. f

In a modification, instead of the knuckle joint being positively locked by a toothed cotter, a plain cotter may be employed adapted to engage either a plain periphery of the knuckle member, or suitable facets on the latter. y

It is to be understood that the knuckle joint may be locked in its adjusted position by any convenient means. For instance, as shown in Fig. 8, the pin 7 may have a serrated, square or other non-circular sectioned middle part 32 engaging a corresponding serrated or non-circular hole in the tongue member 3 of the joint and provided at one end with a head 33 having its inner face serrated to engage serrations on the outside face of the fork el, as at 34, while at the other end a serrated washer 85, feathered to the pin 7 by the key 36, can be taken intoV engagement with serrations 37 on the jaw of the fork 4 by means of the nut 8. Serrated

washers

10, 10, are tted in recesses of the tongue 3 as in the previous form. v

The support or upper part of the bracket may be of any suitable type. It may, for

instance, be of the usual forked type engaging sockets on the sides of the lamp, the stem of the fork being knuckle jointed to the socket pillar.

The invention is equally applicable to motor-cycles, in which case the socket may be formed by the handle-bar stem.

Having lf'ully described my invention, what I desire to claim and secure by Letters Patent 'is l. A lamp bracket for vehicles and the like comprising a stem for attaching to the lamp, a pillar, a knuckle joint comprising fork and tongue members between the lower end of the stem and the upper end of the pillar, the op osite plain faces of the tongue member vaving recesses, friction Washers having both faces serratedlocated in said recesses in the'tongue member and engaging the plain faces ot' the fork member, means for locking the joint in different angular positions, a split socket receiving the pillar, and means for contracting the socket around the pillar to yfix, the latter in different angular positions within the socket.

2. A lamp bracket for vehicles and the like comprising a stein adapted to be attached to the lamp, a pillar, aknuckle joint between the lower end of the stem and the upper end of the pillar comprising fork and tongue members, a clamping nut on the joint pin for tightening the joint, a locking pin passed through the fork niember of the joint so as to engage the periphery of the tongue'member, a socket receiving the pillar, and means for fixing the pillar in different angular positions within the socket.

3. ik lamp bracket for vehicles and the likecomprising a stem adapted to be attached to the lamp, a pillar, a knuckle joint comprising fork and tongue members bei tween the lower end of the stem and the upper end of the pillar, a clamping nut l on the joint pin for tightening the joint, a

locking pin passed through the fork member of the joint and having longitudinal teeth engaging teeth on the periphery of the tongue member, a socket receiving the pillar and means for xing the pillar in different angular positions within the socket.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

. Y EUGENE GEORGE CAMELINA'I.
