LAMP-BRACKET.

Specification of Letters Patent.

Patented Dec. 23, 1913.

T0 all whom itmay concern.'

Be it known that I, HENRY ALEXANDER GOFF, a subject of the King of Great Britain, residing at `Middle Iill, Englefield Green, in the county of Surrey, England, have invented certain new and useful Lamp-Brackets, of which the following 1s a specification.

This invention relates to improvements 1n lamp supports or brackets for use on motor cars and in other situations in which provision is made for effecting the angular displacement of the lamp in a horizontal and vertical plane relatively to the vertical center line of the lamp and horizontal center line of the bracket or support.

For the purpose of the present invention the support consists of a hollow carrier of approximately L formation. The extremity of one portion is provided with notches or indentations to engage with a spring controlled bolt or ball carried in the lamp casing. The extremity of the other portion is adapted to work in a sleeve forming part of a bracket which is capable of attachment to the dash board or other desired surface. The last mentioned extremity may be capable of moving telescopically in the sleeve and of assuming various angular positions relatively thereto the parts being secured by means of a nut device. The said extremity may however carry a spring and be formed or provided with rojections or notches whereby engagement 1s eected with corresponding notches or projections formed in or on the bracket or on a bushing associated therewith.

In order that the said invention may be clearly understood and readily carried into effect, I will describe the same more fully with reference to the accompanying drawings, in which Figure 1 is a side elevation of a lamp and bracket embodying the features of the invention, the parts in dotted lines indicating some of the various positions into Vwhich the lamp may be put. Fig. 2 is a view in section, 'with certain parts in elevation Showing the construction of the vlamp and its socket or bracket joint. Fig. 3 is a view partly in elevation and partly in sect'wn ithistrating a method of constructing the socketer bracket joint when it is not desired to embody therewith the means t packing away the supplemental length of conductor. Fig. 4 is a vertical sectionl of a modified form ofthe lamp and support or bracket. Fig. 5 is an end view thereof indicating` in broken lines angular displacement of the lamp about the horizontal center line of the support. Fig. 6 is a view partly in section and partly in elevation showing a 4further modified form of the support and bracket. Fig. 7 is a transverse section taken along the line 7 7 in Fig. 6. Figs. 8 and 9 are `-views illustrating a simplified construction of the locking means for insuring the angular disposition of the lamp and support.

The bracket A which is adapted for attachment to the dash board or elsewhere is tubular and is arranged telescopically, the outer end B being formed or provided with a spigot or seating device for entering a socket c carried by the lamp C. The two parts of the telescopic bracket may be adjusted as regards their length by means of a locking ring or nut a or other suitable device. The said spigot or seating device b is formed with a groove b1 and a notched or toothed ring or the like b2, the former being provided for the reception of a projection Z13 carried in the socket c of the lamp C, and which engages in the groove b1 and prevents the withdrawal of the lamp from the bracket, except when the projection b3 coincides with the groove b* which also permits of the lamp being placed in position on the seating. The lamp as aforesaid is capable of angular movement, around the bracket, but in order that the lamp may be locked, at any angle around the bracket, a spring controlled pawl device b5 or the like mounted in the socket c is provided for engagement with notches formed in the aforesaid ring b2. The aforesaid bracket A, B is hollow and the necessary conductors E are threaded through the same while the seating Z) contains a suitable contact device e from whence a yielding metal leaf or blade c1 or other convenient device may be arranged to convey the current to the lamp c2.

In order that the lamp may be employed at a distance from the bracket, the usual 'form of su ilernental lead consistinfr of a suitable length of conductor c3 may be connected with the main conductor in the bracket, and with the aforesaid contact dcvice eso that the said lamp may be removed from its socket and utilized at any diswhich is adapted to engage with notches or teeth 1X formed at the upperend of the spigot 1. 4The current is conveyed to the lamp 5 by Vmeans of the leaf'llor blade 6, similarly to the method described with reference to Figs. 1 and 2. The socket 7 for the lamp maybe carried by a-disk or partition 8 or be mounted separately as shownv and the space between the said partition and the'back 9 of the lamp may be utilized for containing the aforesaid supplemental lead or conductor; same being provided with suitable adapters if required whereby connection may be made with the spigot 1 and leaf or-blade 6. The supplemental leadmay be simply'placed in the holder therefor or be arranged therein in an orderly manner. The spring controlled bolt 4 may .bewithdrawn from engagement with the teeth 1x of the spigot 1 by meansof the stud pin or holdfast 4".

Referring to Figs. 4 and 5, 10 is the hollow carrier through which the conducting wire 11 'for supplying the electric current to the `lamp 12 passes, the said wire being led to the contact 13 at the end of the hollow carrier 10. 'lihe lampjs provided with a springcontrolled bolt or stop-1 4 which is adapted to engage by its outerl extremity with holes or indentations 1'5'formed around the upper end of the hollow carrier 10. rllhe socket 16 pertaining to the lam 10 carries a spring contact 17 which norma ly bears on the contact 13 and thereby enables the circuit 4ot' the lamp to be completed. The aforesaid bolt 14 is mounted in a holder or casting 18 which adords a socket 19' for the reception of the upturned end or" the can frier AlO'and whichv is secured to the casing 20 of the lamp. 21 is the retlector and 22 the front glass `which is carried by the ring 23 screwed to the casing 20. The extremity oit the carrier 10 remote from the lamp is mounted in a bracket 24 of hollow section and having ears 25 25 for eiiecting its attachment to the dash board or other surface. The said carrier is provided with a washer or errule 26 whereof the periphery is grooved as at 27 for nearly the entire circurnference, a stop such as a grub screw 28 bein adapted to` work in the said groove and y means oit -jthe ungrooved portions of Loeaova the washer 26 which forms anabutment, the carrier is prevented from making a complete revolution in the hollow portion 24 of the` bracket. Another way of preventing vthe complete revolution whichmay be `found convenient in some cases would be by forming or providing-a projection or extension of the nut 29 as indicated at 30 anda pin or lateral projectionf31 on the carrier 10. When using this latter arrangement the groove 27 may extend for the entire circumference of the washer or ferrule 26. vBetween the latter and the inner end of the nut 29 is a spring 32. The washer or-ferrule 26 is adapted to engage by means of projections and recesses with a' hardened washer 3 3 which is secured in the inner end of the hollow bracket arm 24 by means of a taper pin 34 or other convenient device. The pro- `ections and recesses on the washers 26 and 33 are indicated at 35 and 36 respectively. By means of the bolt 14 and holes or recesses 15 the lamp may be turned to any angle about the upturned part of the carrier 10 and the latter may be turned to any desired angle in the part 24 of the holder or bracket, the washers 26 and 23 by virtue .of the projections and recesses 35 36 enabling' the car-4 rier 10 to be locked or held owing to the ade jacent surfaces of the said washers being held in close contact by the pressure of the spring 32. The groove 27 being wider than the diameter vof the stop or grub screw 28 enables the washer 2'6 on the carrier 10 to move away from the washer 33 to such an extent that the said washer 26` is rendered free to, rotate upon the washer 33 so that the adjustment of the carrier 10 may be eiected. The wire 11 is lechthrou'gh the back of the part of the bracket which is formed or provided with the ears 25 and thence through a hole in the dash board to the source of current.

in Figs. 6 and 7, the carrier 10 is also of hollow 'Y construction but it is vmounted in an elongated lhollow. or tubular bracket piece orfholder 37 formed or provided with lugs 38, 38, whereby attachment is'made to the dash board 39. The holder 37 is formed for action, in edecting the angular adjustment of the carrier- 10 is rendered similar to that pertaining toL the construction described with reference to Figs. 4 and 5. The wire 11 is brought out at the'end of the device and is connected with the'source of current in any convenient manner.

Referring to Figs. 8 and 9 the end of the hollow carrier 10 which enters the tubular part 24 of the bracket, is formed with holes or indentations 41 into which a ball 42 engages when the parts are ,in position, the engagement being maintained by means of the blade or leaf spring 43. 5t-similar ary engagement with the washer 40 whereby the rangement .of leaf spring and ball may be employed in the socket 19 of the lamp.

In the drawings I have illustrated the invention as applied to an electric lamp but it will be obvious that other illuminating devices may be employed. y

What I claim and desire to secure byI Letters Patent of the United States is 1. In a lampsupport or bracket for use on motor cars and in other situations, the combination of a bi-part hollow support for an electrical conductor, said support being adapted for angular displacement in a vertical plane, a lamp socket adapted to rotate around the same, contacts for preserving anl unbroken circuit during rotary movements of the lamp, and means for locking the said socket and the hollow support respectively.
