  • Figs. 7 and 8 indicate how the parts I of the body and the contact means carried by them may be modified and arranged so that a series connection of the arms can be obtained. It will be understood, however, that the form of the parts I shown in Fig. 7 is equally adapted for a parallel connection of all the arms by the form of contact means just described.

Specification of Letters Patent.
Patented Nov. 26, 1912.
Application filed January 6, 1912. Serial No. 669,777.
To all wlwm it may concern:
Be it known'that I, WILBUR H. FISHER, a citizen of the United States, residing at Conneaut, county of Ashtabula, State of Ohio, have invented certain new and useful Improvements in Chandeliers and Fixtures, of which the following is a specification.
My invention relates to chandeliers and fixtures intended to carry electric lights, and its object is a novel fixture possessing various advantages.
Fixtures of the general type with which my invention is specially concerned comprise a body or junction part intended to be supported from a ceiling or a wall and a plurality of arms or branches extending from said body part and supporting electric lamps.
My invention comprises various features of construction and various combinations and arrangements of parts, etc., which can best be disclosed through the description of a fixture embodying it.
While the chandelier hereinafter described represents the bestform or embodiment of my invention at present known to me, so that many of its specific details are important on account of their specific advantages, yet the invention is not confined to such details, but presents features of a more broadly novel character which will appear hereinafter and will be particularly indicated in my claims.
Although my invention can be embodied and applied in electrical fixtures of various sorts, I have herein shown and described an electrical fixture designed for the use of electricity only.
In the accompanying drawings, Figure 1 is an elevation of one style of chandelier, one of the arms being shown as withdrawn therefrom, and several of the other parts being shown as displaced from their ordinary positions or broken away in order t( make apparent features which would other wise not appear. Fig. 2 is an elevation of a somewhat different style of chandelier, various parts being broken away to show the interior construction, and a part A associated with one of the arms bein shown as withdrawn from its ordinary position. This style of chandelier differs from that shown in Fig. 1 as re rds features connected with its support,-t e differences being such as specially adapt it to be arranged close to the ceiling. Fig. 3 is a view of the junction part or body B of the chandelier shown in Fig. 1 as seen from beneath when the part L shown in Fig. 1 is out of the way, the fixture being turned 30 degrees counter-clockw se from the position shown in Fig. 1. Fig. 4 1s a perspective view from above, partly in section at a plane corresponding to the line 44 in Fig. 3, showing various parts comprised in the body, some of the parts being separated from one another in order that the interior conformation and arrangement may be visible, and the parts S and I being shown as cut or broken away for a like purpose. Fig. 5 is a plan view showing the lower of the parts I appearing in Fig. 4 wholly removed from most of the other parts there associated with it, and in its entirety. Fig. 6 is a fragmentary section at a plane corresponding, say, to the line 66 in Fig. 3, showing an arm in position in one of the arm-holes in the body, certain of the parts shown in Fig. 3 being omitted. Fig. 7 is a plan view illustrating a modification of the parts shown in Fig. 5; and Fig. 8 is a diagram illustrating the arrangement of electrical parts according to this modification. Fig. 9 is a perspective view of certain of its parts removed from an arm; Fig. 10 is a perspective view of some of the same parts when removed from a sleeve in which they are inclosed in Fig. 9;'Fig. 11 is a section through the part A on a plane just above the upper edges of the parts A in Fig. 10 illustrating the form and arrangement of the parts shown in Fig. 10; and Fig. 12 is an enlarged detail view showing the manner in which a wire may be attached to one of the parts A shown in Figs. 9, 10 and 11.
I will first describe in a brief way some of the general features which are common to the chandeliers shown in Figs. 1 and 2. It is to be understood, however, that except as indicated the whole of the following description applies to both these styles offixture. As shown in Figs. 1 and 2, a chandelier of either of the styles illustrated comprises a junction part or body proper B, removable arms A, and additional parts by which the chandelier is supported. The junction part or body B has holes or sockets 6 adapted to receive and support-the arms A; and the body and the arms comprise electrical circuits, and also contact means for combining these several circuits so as to form electrical connections for the lamps when the arms ml in )lace intli'e arm-ho es; and. provision is ma e so thatwhen'inserted binthebody fluthe case accidental disp acement of the arms. may be prevented by suitable engagement of the arms in the arm-holes to keep them from turning and suitable locking means adapted to secure them against-being withdrawn. lVliile the arm contacts may serve for the engagement of thearms in the body to prevent them from turning, or as a looking means to prevent their withdrawab'or both, it-is pre erable' to make other or additional provisions for this purpose, articnlarly if the arm contacts have the iighly advantageous form of yielding metallic members a projecting from the ends of the arms as shown at the right in Fig. 1.
I will now describe how the body B may be constructed for both the illustrated styles of chandelier, and the manner in which it is mounted and supported in each of them. As will be seen from Fi s. 1 and 2 the body It comprises a part I w iich carries contact means with which the contact means on the arms are engaged when the latter are inarms are received and engaged so as to pre-" vent the arms from turning. The necessary insulation of the contacts and other electrical parts is best secured by making the part. I itself of insulating material, in which case it may be desirable to secure it to a metallic member Y. As shown, the part I is in closed by a shellor shrouding S, so that/ since the term body alone may be under f stood as referring either to this mnerjunc tion part. I or to the junction part or body B as a whole-the part I may be distinguished as the inner body. The shroudin S not only forms an ornamental easing junction part I, but also comprises outer portions s of the arm-holes or sockets b,- whieh portions may serve in the securing of the arms against withdrawal and may be internally threaded (as shown) for this purpose. The holes a may be made relatively argc so as to allow the projections a on the arms to pass them lliie easily. As shown, the interior )art has eight converging sockets i whic i are arranged with 30 and degree spacing (see Figs. 4 and 6), so that by the use of the )roper ones a chandelier having two, three, our, or six equally spaced arms can be constructed; but for the sake of uniformity of ap earance the'shrouding is nevertheless 'ma e with" twelve "equally As shown, the 'arins-,-are-- not.
or thespaced holes a and the four blind ones closed byornamental screw. plugs 13 (see Figs l,
'2and 3),.as also the others at any time not in us'e.'
.,The-.meinber Y to which the insulating inner body I is secured (see Figs. 1, 3 and 4) is preferably not. a portion of the casing or shrouding S, but a separate part (made, for exam le, of cast iron). The part S, however ias an inwardly extending flange s (see Fii. 4) which is clamped between the parts i and the lower side of the part I. The part S is definitely alined in proper position with respect to the other parts by the screws-or bolts Y which serve'to secure the part- I to the part Y, these screws passing'through holes in the flange a and extending on up through holes i in I to engage nuts (not shown) which rest in an ular dcpressions in the upper side of I. 'ashers z of any suitable material (as card board, for exam le) may be placed between the inner body 'and the flange 8'. -\Vhen the part I is made of porcelain or any other more or less frangible material, the member Y is useful to-reinforce and brace it, as well as in other ways which will presently a )pear.
Inthe style of chandelier and the construction shown in Fig. 1, there is afoot F (of cast iron, for example) which is adapted to'be "secured to the'ceiling, this foot having a portion which fits into the hollow part f and is secured therein by a cotter pin f", and
the part in turn fitting into thehollow stem .or standard X and being likewise secured therein by a cotter pin The current supplywires 10 which pass down from the ceilmg through the standard X'enter throii h a ole'in the side of the part f. lVhen-t e chandelier is fully assembled, the foot. and
the associated parts are covered by the threepart cam py C, which is held in place on themember by a set screw 0. There are also a part I) (held in place on the standard X by set screw (1) and a bottom shell part I (held in place by screws Z that. enter holes yin a rim 3 on the part Y) which serve a purpose similar to t wt of the cano y The standard X extends down through the hole 1" in the inner body I (see Fig. 4), and
its lower end fits into the hub of the part Y and is secured therein by the cotter pin (see Figs. 1 and 3). When the part D is brought down so as to fit over the rim 3 on the upper edge of the shrouding S and secured in place, it helps to make the body ll firm and rigid with respect to the standard. In the construction shown in Fig. 2, there are'lilt'ewise a foot F and a stem X; but the stem X'is threaded directly into the foot and the wires 10 are arranged outside of the stem, and both the stem and the foot. are in closed by the two-part canopy C and the part D, which fit directly together as shown.
.The stem X extends through the hub 7 as well as through the inner body I, and on its lower end is threaded a nut N which clamps the part C and D between the body roper and the ceiling. The bottom shell is arranged and secured just as in Fig. 1.
I will now proceed to describe in detail a construction and arrangement of the inner body I and the electrical parts and connections associated with it which are e ually adapted for both the styles of chan elier shown, also indicating the particular arrangement of the inner body I with respect to other parts that may be preferred in each style. As will be seen from Figs. 1 and 6, there are at the inner end of each of the sockets 2' in the inner body I two inwardly extending chambers i which are in effect prolongations or extensions of the socket and serve to receive the contacts a which project from the ends of the arms A. In the arrangement shown, (see Figs. 4, 5, and 6) the contact means carried by the inner body I are arranged centrally with reference to the sockets i and are completely inclosed in it and when an arm is in place in a socket they lie between the arm contacts a and. are engaged with them at 2" in the chambers i, opposite or adjacent the inner end of the socket proper,--preferably in a manner hereinafter described. For the sake of combining strength, simplicity, and the best insulation, it is preferable that both the outer portion of the body I which contains the converging sockets z' and the central part which contains the contact means be of insulating material, and that the outer and central portions be integral. The body I may, however. advantageously comprise parts separable through the center where the contacts are arranged and the chambers 2'' located in a direction transverse with respect to the sockets. As shown (see Figs. 4 and 5) the body is made in two parts I each of which contains part of each socket i and its grooves 2" together with one of the chambers 2" opening into the socket, and also accommodates the contact means exposed at 2' in the chambers i lying in it; and the two parts are exact duplicates of one another. The wall or partition 11" by which the chambers 2" associated with each socket are separated may consist of insulating means interposed between the halves I of the body, and, in particular, of a portion of a flat annular member I of vulcanite, fiber, or any suitable insulating material, (see Figs. 4 and 6) inclosed between the halves, the abutting faces of the two halves having broad, shallow annular depressions or grooves i to accommodate it. The contact means exposed at i in the chambers i in the several halves may advantageously be arranged between their juxtaposed faces in passages, depressions, or recesses at the bottom of the grooves 2'. As
shown in these figures, the depressions have themselves the form of annular grooves 1'. each made up of a number of short curved grooves, and two annular members or rings I constitute the contact means: thus when the arms are put in place in the sockets they will all be connected in parallel between these two contact members whose engaging portions i associated with each socket he in the path of the contact means on an arm as it enters the socket. Each of the members I may be formed of a piece of fairly large copper wire bent to shape, and its current connection may consist of a portion of the wire bent so as to extend radially outward from the ring in an extension of the groove 11 to the hole 17 just beyond the edge of the shallow annular depression i Here the wire is bent at right angles to the plane of the ring and attached to one of the supplv wires w referred to above. In the case of the contact member I lying in the lower half of the body I, this portion extending at right angles to the plane of the ring or annular portion and the attached supply wire w pass down through the hole 1' in the same half. In the case of the contact member I lying in the upper half, this portion and the attached supply wire 10 do not pass through the hole 2' in the upper half at all. but instead pass down throu h the heel i in the lower half, this hole lying 120 degrees from the hole 2' in the lower half. The fitting together of the two halves I in any but the proper manner with the holes 2' in them 120 degrees apart is insured against by two dowels 1' and two corresponding holes 2' with which each half is provided.
In the case of the construction shown in Fig. 1, the part I from which the wires 1/ issue will preferably lie next the part Y and form the lower half of the body I, as just described, and the wires 11: will be bent upward through the hole 6 so as to pass up through the standard X. \Vith the construction shown in F ig. 2, however, the inner body I will preferably be secured to the part Y in a manner just the reverse of the above, so that the part I from which the wires issue will lie away from the part Y and form the upper half of the body I, and the wires w will not be bent to pass through the hole 2, but will extend directly upward to the ceiling.
I will now describe the construction shown in Figs. 7 and 8, which indicate how the parts I of the body and the contact means carried by them may be modified and arranged so that a series connection of the arms can be obtained. It will be understood, however, that the form of the parts I shown in Fig. 7 is equally adapted for a parallel connection of all the arms by the form of contact means just described. As shown in Fig. 7, the holes i and i in each half of the body are replaced by a pair of holes 2' and i" and corresponding approximately radial grooves, and there are also two additional pairs of such holes and grooves. There are also a lurality of notches i in the outer edges ot the grooves i. The contact means in the grooves i consist of a plurality of electrically isolated sections or seg ments, the ends of these contact sections being bent outward so as to lie in the notches 5" or in radial grooves not otherwise'occupied and keep the sections in their proper places. Insulating pieces may, if desired, be placed in the groove 2' between the contact sections. As shown, the sections are ar ranged to produce a series connection of the arms in the sockets marked I, II, III, and IV. Of course only the contact sections 1", I and I in the lower half of the body appear in Fig. 7; but in Fig. 8 the contact sections I and I in the upper half and their arrangement with reference to the chambers i and the sections I", I, and I in the lower half are diagrammatically indicated. (It will be understood that where the upper contact sections overlap the lower ones cir' cumferentially they will most naturally be arranged directly above them instead of in the relative radial positions which for clearness of illustration the lines representing them occupy in Fig. 8). At each arm current passes from an upper contact section to a lower contact section, or vice versa, as will be readily understood; and in each of the contact sections except the two terminal sections I and I the current passes from one arm to the next arm. By a slightly different arrangement of contact sections it is easy to adapt the fixture for two, three, or six serially connected arms; and it is also easy to obtain a connection of various arms in series parallel or parallel series. Of course not all the holes 2' and 2' or their radial grooves are needed for the four-arm series arrangement illustrated, nor all the notches z' those not shown as in use being intended to provide for other arrangements and connections of the arms.
I will now, finally, describe the chandelier arms A, first setting forth their external features and the manner of their insertion in the bodv, and then their internal features and construction. Reference has already been made to the projections a which prevent the arms A from turning in the sockets, and it will readily be observed (see Figs. 1, 5. and 6) that in consequence of the proportions and arrangement of the parts these projections make it impossible to insert an arm very far in a socket except in one or two POSltlUlS 180 degrees apart. It will also be observed that before the contacts a on an arm can approach the portions i of the confacts I which they engage in a socket the projections a must be in the grooves 2" and the insulating partition 2" must be between the contacts a, so that the short circuiting of the fixture or injury of the contacts that might otherwise result from the careless introduction of an arm askew is safeguarded against. As it is advantageous that the yielding contacts a be not merely pressed against the contacts I (with which, as shown, they engage laterally) when the arms are in place in the sockets but rather in definite gripping or interlocking engagement with them, these contacts a may be made quite resilient and may have the bent form shown in Figs. 6, t), 10, and 11. Then as an arm is pushed into a socket the diverging ends of these contact springs will first be forced apart by the 0011- tacts I and then come together of themselves so that the contacts I will rest inthe sharp angles of the springs just beyond their diverging portions, and the parts will thus be retained and locked in the relative positions shown in Fig. (3. Of course the engagement of the contacts a and I in this manner of itself tends to prevent the arms fromturning; but it is obviously preferable not to subject the contacts to strain of this kind, but rather to provide the projections a and grooves 1" already described. It is preferable also not to rely entirely upon the spring contacts a as cure the arm against withdrawal from the socket, but to provide additional locking means. For this purpose an externally threaded collar .A' may be screwed into the outer portion a of the arm-hole after the arm has been pushed home so as to engage the projections a on the arm and thus positively prevent its withdrawal (Figs. 1 and 6).
Referring now tothe construction and internal features of the arms, the projections 0 which co-act with the collar A as above described may conveniently consist of tongue-like portions punched from the metal of the arm and bent out-ward as shown in Figs. 5 and 6. The projections a next the end of the arm may consist of the protruding ends of a pin A (Fig. 5) which extends through the arm and serves to hold certain parts in place within it. As shown in Figs. 9, 10, and 11, the parts within the arm comprise an insulating sleeve A (of vulcanite or insulating fiber, for example) pierced with two holes a (one not shown) which serves as an insulative lining in the end of the arm, a pair of metal strips A whose free ends form the spring contacts a, two wires A which are attached to the other ends of the strips A and conduct the current to the lamps carried by the arm, and a a locking means to seflat-sided insulating part A (of porcelain or other suitable material) laterally recessed at one end and having a shallow groove a across the other end, and also pierced with a hole a. The strips A are bent to conmums form to the sides of the insulatin piece A and overlap its end somewhat in t e groove a", so that when these parts are assembled (Fig. 10) and inserted in the rather tightfitting sleeve A till the end of the insulating piece A is about flush with the end of the sleeve (Fig. 9) they are firmly held in proper position, and it only remains to insert the sleeve in the arm so that the hole a and the holes a in the sleeve register with the holes in the arm and to secure all the parts in place by means of the tight-fitting pin A The wires A may be secured to the ends of the strips A which lie in the recesses in the part A in various Ways, that illustrated in Figs. 10, 11, and 12 being very simple and efi'ectlve. As here shown, the end of each strip somewhat resembles a fishs tail. The extreme end has a fork-like form and is bent up, as shown, and two fins which project from the narrow portion of the strip near the extreme end are also bent up to form a trough in alinement with the fork. The wire is laid in the trough and extends through the fork, and the sides of the trough are squeezed together upon it. If desired, the joint may be made still more secure by the application of solder.
The lamp sockets may be attached to the arms in any preferred or approved manner.
The advantages of the chandelier construction which I have described are numerous. In the case of the style of fixture shown in Fig. 1, the body B with the stem X attached and the arms A can be wired in the factory and sent out as individually complete and independent standard parts in substantially the condition in which they are shown in that figure,-the part D being of course fastened down in its normal position against the body,and the canopy C and the bottom shell L can likewise be manufactured as independent standard parts. In order to assemble and install this style of fixture, it is then only necessary toattach the foot F to the ceiling and set the canopy C in the usual manner, to fasten the bottom shell L in place with its two screws l, and to insert the arms in the body and lock them with their screw collars A. In the case of the style of fixture shown in Fig. 2, the body B can be sent out with the part D very much in the shape in which it appears in Fig. 2. In order to assemble this style of fixture, it will then only be necessary to attach the foot F to the ceiling, put the body B and the part D in place with the canopy C above them, screw the nut N on the standard X beneath the hub y of the part Y until the parts are firmly clamped between the top of the body and the ceiling, and fasten on the bottom shell L and insert and secure the arms as before. None of the parts of either style of fixture require much space; and any of them can be packed for shipment :in very small bulk, either together or separately. Again, a fixture of any desired number of arms,-two, three, four, or six,-can be built up by simply unscrewing the proper plugs B from the body and inserting the arms, and the number of arms can be altered with equal facility after the fixture has been installed for years. From a very small number of different standard parts of each kind a great variety of designs can be produced, and fixtures already installed can easily be altered in design as desired. The fixture is simple and strong in construction, and its parts are likewise few and simple, so that they can be very easily and cheaply manufactured. All the parts comprised in the arms and in the body B can be assembled expeditiously and cheaply. When the arms and the body have once been made up and tested in the factory, it will hardly ever be necessary to take them to pieces, for there is nothing about them to reak or get out of order; and if after a fixture has been installed and in use one of its arms should need repair, it can be sent back to the factory for this purpose without removing or dismantling the fixture, or even rendering it unsightly.
