LAMP-Haltern;

Application led April 22, 1909. i Serial No. 491,478.

To `all whom may' concern:

Be it knownv that I, Libri) B. HORNBECK,

` of Minneapolis, Hennepin county, Minnesota,

have invented certain new and-useful linprovements in Lamp-Hangers. of which the following is a specification.

The object ofmy invention is to provide a Support or hanger for' an incandescent light, which will take up the jar or shock incidentalv to the moving of furniture around a house, Athe passing of street carsy or any jar that would produce vibration ot" the lamp suilicientito cause breakage of the filament. l

A further obj-eetof the invention is to provide a lamp hanger havin means to pre vent the `transmission of vi )ration to the lamp and hence'adapt-y it for use on railway cars.

The inventlon consists generally in various constructions and combinations, all as hereinafter describedand partlcularly pointed -out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a ver-' tical, sectional view of anineandescent lamp holder, embodying my invention, Fig. 2 is a sectional view' illustrating the construction shown in Fig. 1 taken on a section line at an, angle to the section line of Fig. 1.

Fig. 3 is a sectional View on the line X-X of Fig. 1, Fig.` 4 is a sectional view on the "Inihe drawing, 2 represents a d omc or casing and 3 a ppe or hangerin which the Wires' 4 are con ucted to the lamp. The dome 2 has an opening 5 in its to in which a shell 6 is fitted and supported y a sleeve.

7 onthe lower end of the pipe 3. The dome closes the top of theshell and forms there'k with a Casin inelosing the lamp socket and supporting t e globe. The dome 2 is adapted to slide on the shell 6 tol allow the lamp to adjust itself at an angle tothe vertical,

for the convenience" of the user, or to permit swaying of the lamp when it is used on moving car. Below the dome 2 is a cylindrical shell'8 having its upper end teleseop ingwith the lower portion of the dome 2 and provided at its lower end with a spring device 9, which engages and supports a shade or globe 10. Within the dome 2, a' block 11 of insulating material is arranged. A bushingbfinsulatin material is provided within the sleeve 7 -an a bar 12, also of insulating v material has its ends supported in the sleeve Specification of Letters Patent,

Patented May 3G), 1911.

7 'anu carries an insulating yoke' 13, which is attached at its ends to eye bolts 14,.'secured to the block 11. ,l prefer to' provide this insulating bar and yoke to'prevent short circuiting, in case the insulationisworn oit the wires #1. The bushing also prevents the wires from contacting with the metallic sleeve. The wires 4 are attached to bolts 15, which 'pass through the block l1l and conductors 16 lead from the bolts 15 to a lamp socket 17. This socket is carried by a.4 block 18. also otuinsulating material, and comparatively light coil springs 19 are interposed hetween the blocks 11 and 18 and support the lamp, forming a yielding carrying means therefor. The socket 17 is adapted to receive an ordinary incandescent light 2O arranged within the globe 10. Beneath the block- 18 is a butter plate 21, having an opening 22 to receive the lampvsocket-.-lhe butter pla-te is supported by rods 23 on the block 11, said rods passing through holes 24 in the block 18 and through brackets 25, which are lscoured to the block 11 andA to the cylindrical shell 8, which in turn, supports the globe '10. l am thus able to suspend thp globe and the shell, by which it is carried from the pipe 3, and relieve the lamp socket entirely of the weight of these parts, which are usually connected with'the socket and render it impracticable to employ light sup-V porting springs to take vup the vibration and prevent damage to the lamp filament. Seats 26 are formed in the butter plate 21, to reive balls 27 of yielding material, such as rubber. These balls are adapted to Contact with theconeave surfaces28 provided in the under siderofthe block 18 and cushion the said block. The distance between the block 18 and the plate 21 can be regulated by the adjustment of the rods 23.

' It will be not-ed that an important feature f of this inventionisthe manner of supporting the lamp socket and the lamp independently ofthe globe, and at the same time proy viding means whereby the angle of the fixture can be varied to compensate for swaying or rocking of the car, in which the lamp may be mounted. It will also be noted that the dome can he raised to expose the blocks 11 and 18 and allow access to the connections without the necessity ture 'from the hanger;

I claim as my invention. 1. The combination, th ajcasing and a1 globe carried thereby, block yieldingly" .i

suspended within said casing and having a lamp socket and a lamp fitting therein, said socketand. lamp being supported independently of said casing and globe, the yielding support ot' lsaid block allowing it to swing laterally and move vertically to take up shock or vibrationsubstantiall \7 as decoil springs, and a lamp socket depending i from said Second block.

4. The combination, with a hanger, of a casing, a block vicldlngly suspended therein 2l\,anfl having a lamp socket, and means below said block for vieldingly resisting its downbaard movement. Y

' The eornlnnation, with a lamp hanger,

Y `of a casing, a block Within said casing havin;r a lamp socket, a buffer arranged below said block and balls of yielding material carried by said buffer in the path ot' said lilOtl-C.

6. The combination, with a pipe, of a shell supported thereon, a dome having an Opening to receivesaid shell and adapted to? slide thereon, a block inclosed by said dome l and having an independentsupport from said pipe, a lamp socket carried by said block and said dome being,r capable of sliding vertically on said pipe to expose said block and socket.

7.The combination, with a pipe, of a casing` supported thereon, aflamp globe carried b v'said casing, an'd a lamp socketdepending Within said casing and yieldingly supported independently of said casing and globe, for the 'purpose specified.

8. The combination, with a hanger, of a..

. block. a yoke mounted onsaid block, a bar supported in said hanger and carrying said yoke, and a Vplate having a lamp socket yieldingly suspended beneath said block, substantially as described.

9. A device of the class described, eomprising a casing, a block therein having a lamp socket, a serles of sprlngs yieldi-ngly .supporting said block within said casing,

means in the path of said block for yieldingly resisting downward movement thereof, and a globe.

l0. The combination, with a hanger, of a yieldingly supported lamp socket pivotally connected therewith,- a casing inclosing said socket and said pivotaluconncction, a shell having a sliding Contact with said casing and permitting the'tilting` thereof with respect to said hanger without exposing said pivotal connection.'

11. The combination, with. a hanger, of a casing supported thereon, a lamp globe carried by said casing, a lamp socket, a spring supported block whereonsaid lamp socket is mounted, and a guide permitting a limited lateral oscillation of said block and socket.

l2. The combination of a hanger, a lamp socket pivotally connected therewith, a casing inclosing said socket, a shell having a sliding contact with said casing and permitting the tilting thereof with respect .to said hanger, for the purpose specified.

ln witness whereof, I haye'hereunto set my hand this 17th day of'April 1909.
