Application-tiled August 5, 1912. Serial No. 713,278.

To cLZZ.whom it may concern:

Be it known that I, ALBERT SncHnIs'r,

citizen of the United States, residing in the city land county of Denver and State of Colorado, have invented certain new and useful Improvements in Chandeliers; and I do'declare the following to bea full, clear, and exact description of the invention, such as will enable 'others skilled. in vthe art to which it appert'ains to make and use the same, reference being/had tothe accompanyingdrawings, and to the characters of reference marked thereon, which form a part of y invention 'relates to improvements in general character set fort-h in previous patents issued to me, and numbered 1,017,694, dated February 20, 1912; 1,024,369, dated April 23, i912, and 1,024,809, datedApril 30, 1912. A

My present invent-ion relates to certain improvements over the constructions disclcsedv n 1n the aforesaid patents,

whereby the variousv parts of the chandelier structure are more securely connected, and danger of dainaging insulation -of Wires located in the chandelier is made practically negligible.

Having -out-lined in a gene 1al way my present improvement, I will proceed to describe the same in detail, reference being made to the accompanying drawingin which is illustrated an embodiment thereof.

In this drawing: Figure 1 is a section taken through a'chandelier embodying my F ig. 2 is a fragmentary detail view illustrating the manner of connecting one of the end ittings, shown on a lei-ger scale. Fig. 3 is a sectional view on the line 3-3 of the same. Fig. 4-

a detail View of a screw-pin, constituting an inimy improvement. Fig. is a View similar to Fig. 2, but showing a slightly modified form 6 is a fragmentary view of the inner extremity of one`of the tube arms, shown on a larger scale than in Fig. l.

The same reference charactersl indicate same parts in all the views.

`Let the numeral 5 designate a. fixture body in which is located a tube connector 6, which is supported in the said body and connected with tube arms 7 which enter the iixture body through openings '8 inopposite sides thereof, the inner extremities of the of construction. Fig.

the tube arms being fitted over nipples 9, screw-pins 10 being employed to connect the tube arms with the nipples of the tube connector. This screw-pin has an enlarged threaded part 12 adjacent its head extremity, while the remaining portidn 13 of the pin isof less diameter and unthreaded. In applylng these pins the` enlarged threaded parts l2 engage slots 4 formed in the tube arms and threaded openings formed in the nipples 9 on one side. The extremities of the plain portions of the screw-pins enter registering openings formed in thetubes and nippleslon the opposite side from' the said vslots and threaded openings` the said4 registering openings being plain or nn'- threaded. In making this connection, it is only necessary to apply the screw-pins to the nipples 9, care being taken not to insert the said pins far enough to cause their plain or unthreaded extremities to extend beyond the nipplefUnder these circumstances the headsv of the screw-pins will extend above the nipples to permit the connection ot' the tube arms with the nipples, the tubes being so arranged that the mouths of the slots et are in alineinent with the threaded portions of the screw-pins. The tubes are then moved toward the shoulders of the tube coni'iector whereby thetlireaded portions oi the screw pins are caused to engage the slots 4.-

As soon as the adjacent extremities not the t-iibe arms are in engagement with the .shoulders ofthe tube connector, the tube arms are given a partial rotation to cause the screiv-pins to enter the otlset portions oit' the slots 4, thereby Jformingij bayonety joint connections. The screw-pins are then inserted to their limit of movement whereby their headsv are caused to engage the tube arms, While their opposite extremities are iiassed through the registering 'openings formed in the nipples and tube arms on the opposite side troni the slots and threaded. openings in the saine parte. 1df'here the angular slot ilis employed, it will be seen that the tube arms are t. ubi); locked to the tube connector, .since thc tube arms cannot be removed without 'iiist unscrewing the screw-pins tar enough to lisci'igage their plain extremities from the openings in the tube arms, and then giving the tube arms a partial rotation to bring the screw-pins into aiineinent with the portions of the slots' 4;

extending parallely with the axes of the tubes. For this reason it i'. ill be understood that the angular slots may be dispensed with and straight slots employed if desired. By virtue of this peculiar construction ot the screw-pins and thev arrangement of the perforations the assembled parte may be' quickly connected and disconnected, as compared with cases where screws whose shanks are threads ed their entire length, are employed.

To the tube connector 6 is further applied a lower spacing sleeve 1 and an upper spacing sleeve 2. The inner extremities ot these-sleeves engage the connector 6. A rod 3 is` passed through the central opening 14 formed in the tube connector and through theupper and lower sleeves of the structure. The upper extremity of this` rod -isvtl'ireaded into a joint '15, a lock-mit 16 being applied to the upper extremity offthe rod and interposed between the upper extremity of the spacing sleeve 2 and the lower end ot the joint 1 5. The lower end otrthe spacing sleeve 1 engages the bottom ofv the fixture body 5 surrounding the opening in the bottoni of the said body, throng-li which the rod 3 extends. Applied to thc lower threaded extremity oit this rod, and fitted against the bottoml of the canopy on the outside, is a nut- 17 which is countersunk in a recess 1S formed in the bottom knob 19 whose perforation 2() is threaded to receive the rod. The upper extremity of this bottom knob is fitted closely against the bottom of the canopy on the outside.

To the outer extremities of the tube arms are applied end fittings 21 upon iwhich are formed nipples 22 which are inserted in the outer extremities Vof the tube arms and secured thereto by screw-pins 10 of the con-4 heretofore described. These screw-pins, by virtue of the 'facttliat they pass entirely through the nipples and the tubular parts with which the nipples are connected, make it impossible for the. connected parts to become loose, consequentlyY there is no tendency for one part to inove or rock upon the other in such a manner struction that the insulation on the electrical con` ductors which must pass through the connected .part-s, might become worn or destroyed.

The screw-pins 10 which connect the end fittings with the tube arms may be einployed in connection with slots 24 of ausrular shape, whereby a bayonet joint is formeck-see Fig. 2,-or with straight slots 2i,-see Fig. 5.

rl.`he lower extremity of a tube stem 2O is connected with a nipple 27 formed on the upper extremity of the joint 15, by means of a screw-pin 10, the said nipple of the joint inserted in the lower end of the said stein. 'This connection is made in the same which the said pins engage,-

manner as the other screw-pin connections heretofore described. The upper portion of this stem extends into a ceiling canopy Q9 which is supported on the tube stem by a set-screw 29 passed vthrough an opening formed in a bead 30 formed on the lower extremity of the ceiling canopy and surrounding the tube stem. The inner extremity of the set-screw engages the tube-stern with sutiicient force to maintain the ceiling canopy iii its proper position of vertical adjustment. i

with tlieuppei` extremity of the tube'stem, is ay fixture stud 3l which is lconnected with the top of the tube stem by means of a'bolt BQ, a nut 33 beingapplied, the connection is snlhciently loose to permit the chandelier to hang in a vertical position.' rlhe upper extremity of the fixture stud is threaded into the lower end of a joint 34, whose upper extremity is connected, as shown at'35, with an insulating joint 36, this insulating joint' being connected with a member 37 located in a ceiling cavity 38 in which is set an inverted cup-shaped member 39 which is surrounded, and normally entirely concealed, by the ceiling canopy. f

i From the foregoing of assembling the various parts thereof, will be readilyunderstood. For instance, 1n applying the their limit of movement thus securely locking the end fittings in place. The other screwpiii connections will be made in substantially the same manner, and need not be described in detail. By virtue of my iinproved screw stem connections heretofore described, the said parts are much more quickly and easily joined than by any of the devices heretofore employed; for instance, referring to the manner of connecting the tube arms 7 with the tube connector 6, it is only necessary to apply the tubes to theiiipples with the screw-pins properly adjusted. The operator. then can pass a screwdriver downwardly from the top of the fiX ture body and readily screw the pin to po- Within the ceiling canopy, andv connected description, my 'im-,I proved construction, as well as the manner causing the being made in such a manner that the joint end fittings to the tube arms, the

shown in Fig. 3, whereby their plain or unj to enter the offset portions of the slots, after I which the screw-pins will be inserted to. Y

' extremities of the rod for vductors which thermore, by virtue of my improved construction, it becomes l'iracticable to shift the tube connectors, the en d fittings and the Joints employed in connection with the lower extremities ot the screw stems, with the4 screw pins `in place, thus greatly facilitating the work of assembling the partsf Attention is called tothe fact that my improved screw-pin connections are equally applicable to parts which are square, or ot other polygonal shape in cross' section.

However, when the parts to be connected are of polygonal shape it will be understood that the straight form of slot 25 will be employed, since the angular form of slot is only practicable where one part can bc rotated upon the other, at least to a limited extent.

Attention is also called to the fact that the .tube connector G, the tube arms 7, the upper and lower spacing sleeves and the rod 3 passing through the said connector and the said sleeves constitute a rigidly assembled structure independently of the fixture body,

the screw-pins being employed to connect the tube arms with the tube connector and the nuts 16 and-17 applied tothe opposite securing tlie spacing sleeves in position, It, therefore. results that if the fixture body were injured or destroyed, the rigidity and security of the structure would not be interfered with. Itshould be stated, further, that the important object of having the portions 'of the screw-pins plain or unthreaded where they pass through the` openings in the nipples, is that there is nddanger of lin'` juring the'insulation 4of the electrical conmust pass through' these openings. In cases where the connecting screws are threaded'throughout their length,

the sharp. edges of the screw threads are liable to destroy the Vinsulation on the conductors, as the latter are drawn therethrough, 'or during use.

Ha ving :thus described invention, what' I claim is:

1. A chandelier having openings on opposite sides, tube arms entering said openings, a tubeconcomprising a fixture body l' nector within the fixture body, the said connector having nipples which enter vthe extremities of the tube arms, and screwpins for attaching the tube arms to the said connector, the said pins having threaded portions adjacent their heads, the connected parts being perforated to receive the screwpins which pass entirely through the same,

.one set of the perforations in the nipples being threaded to receive the threaded portions otthe screw-pin, substantially as described. l

2. A chandelier comprising a fixture body, a tube arm connectorl inclosed within the fixture body, said connector being vertically perforated, a rod passing through said perforation, upper'and lower spacing' sleeves engaging the tubearm connector at opposite ends,tl1e lower spacing sleeve being interposed between the said connector and the bottom' .of the lixture body, the lower extremity of the rod passing through an opening formed in the bottom of the fixture. body and being threadech'a bottom knob applied to the said threaded end, and a nut also applied to said threaded end and countersunk in a recess formed in the top of the knob.

'3. The combinationof a tube,

-a part. equipped with a tubular nipple,

and a 'screw-pin having a threaded part adjacent its head, and a plain or unthreaded part beyond, the tube and nipple having a slot and threaded opening` respectively on one side adapted to receive the threaded part of the screw-pin, and registering perforations on the opposite side to -receive the plain or unthreaded portion of the screwnn. I 4. A chandelier including a tube'connector, radially disposed tube arms applied to the. tube connector and rigidly secured thereto, upper and lower spacing sleeves whose inner extremities engage the tube connector, a rod passed through the spacing sleeves and an opening formed in the .fronnector, the rod having threaded extren'iities extending beyond thesleeves, and nuts applied to the opposite extremities ot the rod.

.in testimony whereof I atiix my signature in presence of two witnesses.
