HOLDER FOR ELECTRIC LAMPSAND HOODS.

SPECIFICATION forming part of Letters Patent No. 442,472,dated December 9, 1890.

Application filed May 5,1890. Serial No. 350,666. lNo model.) i

To all whom it may concern:

Be it known that I, GEORGE L. BATCHELDER, of Bloomington,in the county of McLean and State of Illinois, have invented anew and Improved Holder for Electric Lamps and Hoods, of which the following is a full,clear, and exact description. 1

My invention relates to improvements in devices for suspending electric lamps and hoods; and the object of the invention is to provide a device by means of which the lamp and hood may be securely suspended and by means of which the lamp or the hood, or both together, may be eonvenientiy lowered by a single rope.

To this end myinvention consists in certain features of construction and combinations of part-s, which will be hereinafter more fully described, and then pointed out in the claims.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the igures.

Figure! is a vertical section showing the suspending mechanism in front elevation and with the lamp and hood in an elevated position. Fig. 2 is a broken vertical section through the hood, showing the lamp partially lowered from the hood. Fig. 3 is a vertical section through the hood, showing the lamp raised in the hood and with the lamp-hooks about to engage the suspending-hooks. Fig. 4 is a side elevationV of the suspending mechanism with the hood removed. Fig. 5 is a detail view, partially in section, of the hoodhook and the slide upon which the hook may rest.l Fig. 6 is a det-ail perspective view of the device for detaching the lamp-hooks, and Fig. 7 is a detail view showing the detachng device for the hood-hook.

The, hollow block A is provided with suitable suspending-eyes a, with an opening A at one end and an opening A2 upon the bottorn, a grooved pulley B, pivoied centrally in the block over which runs the cord C, by which the hood and lamp are suspended and operated, as described' below, and a guard (I, suspended by a spring d', to limit the npward movement otf the rod il. The block is also provided with a hook a upon one side near the bottom opening to engage the hoodhook, as hereinafter described, and a spring b, tixed to the wallet' the block above said hook, to hold the hood-hook in engagement therewith, and to also serve as a detaching device, as described below. The spring b is composed of two similar parallel members having inwardly-projecting beveled portions band an enlarged opening b2 above the said beveled portions, so that when the hood-hook H is raised through the opening b2 and then lowered said hook will strike upon the beveled portions b and be guided through the lower opening of the block A.

The hood D is of the usual construction` and has fixed in its upper portion a vertical hang-board D', to which the lamp-hanging mechanism is aixed. Supported above the hood D is a cross-bar E,upon which the linewires are supported in the usual manner,`and projecting through said cross-bar and into the hood is a tube F, which vertically aligns with a sleeve F below the same. lThe sleeve F is provided upon its front side with a vertical slot F2, extending from the bottom of the Sleeve about half-way up the same, said slot being wider near the bottom, and the lower end ofthe sleeve l1" being beveled upon each side, so that the sleeve terminates in a point F3 upon the back portion of the sleeve.

The suspending-rod G is vertically movable in the sleeve F, the upperend of said rodbeing attached to the cord C, so that by pulling upon the cord C the rod will be raised and by loosening the same it will be lowered. The rod G is provided near its upper end with a laterally-projeeting lug G', which engages the slot FTl ot' the sleeve F and guides the rod sothat the lampyc'onnections will assume their proper polarity when the rod is elevated, as hereinafter described. The rod G has fixed to its lower end a socket Gr2 of the usual forni and adapted lo hold an incandescent lamp; but it is obvious that inf stead of providing au incandescent -lamp socket any form of are lamp may be attached to the rod.

Extending through the top of the hood D and through the cross-bar E parallel with the tube F is a tube c, in which the suspendingbar ll is vertically movable, both of said tubes` being formed in the case lli". The suspending-bar ll is formed at its upper end into a hook ll', said hook being provided with side IOl ' and sleeve K in a vertical lugs h', extending laterally from the body of the hook so as to engage the spring members b', as above described, and said bar is provided with an angular bend H2 below the lowerend of the sleeve e, which limits the upward movement ofthe bar and enables the hood to be suspended thereby. A slide J is suspended in a sleeve K immediately below the end of the bar H, said slide being vertically movable in the sleeve K and having an enlarged upper end J,`suitably insulated from the bar H to limit its downward movement in the sleeve, an enlarged lower end J2 to limit its upward movement in the sleeve, and a depending lip J3 to engage the end of the lamphook rods M, as hereinafter described. The sleeve K is provided near the top with a flat plate K', which is pivoted upon the hangboardD, and suspended above the plate K is an inverted-U-shaped spring K2, the members of which. press against the sides of the plate K', and so normally hold the plate K position.

A stop J4, similar'to the slide J, is fixed to a plate J 5, and said plate is suspended upon the hang-board D opposite the sleeve K and slide J and in horizontal alignment therewith, said stop being held in a vertical position by a spring K2, which is similar to the spring already described, and the members of which press against the sides of the plate J 5.

Fixed to the hang-board D', near the lower edge thereof and upon opposite sides of 'the suspending-rod G, are the plates L, which project below the lower edge of the hang-board D', and which are provided with inwardlyprojecting hooks L', adapted to hold the lamp, as described below.v The said plates are connected Vwith the line-wires L2, and the current passes through the plates and hooks to the lamp.

Pivoted upon the upper ends of the plates L are the angular plates g, said plates being pivoted near their lower ends and having their upper ends provided with spiral springs h, which are fixed to the hang-board D above the ends of the plates g, and which tend to pull the upper ends of the plates into an elevated position. The plates g are provided with laterall y-extendin g portions g', which extend diagonally downward above the hooks L', said portions g having their lower ends formed into two similar members g2, with inwardly-projecting portions g3 beveled upon their upper surface, and a large central opening g5, to permit the passage of the lamphook rods through the same. The plates L and g are connected by suitable shunt-wires fto shunt the current when the lamp is removed. 'lhe plates g are also provided upon their inner upper edges with beveled portions g4, which engage the brushes i', fixed to the plates i", said plates being` attached to the hang-board Dabove theplates g. The plates z' and the plaies i. are connected by wires .12,

thus forming a closed circuit when the lamp is removed.A

The lamp-socket G2 has attached to the upper edge thereof, upon opposite sides, the upwardly-projecting rods M, each rod having upon its outer edge a depending hook M', adapted to engage the hook L' of the plates L when the lamp-socket is raised and be thereby suspended. The sides of the hooks M project laterally beyond the rods M, as shown in Fig. 4. The rods M are pivoted at their lower ends to the bifnrcated frames M2, which are properly insulated upon the socket G2 and project into the interior of the same in the usual manner. The rods Mare pressed outwardly by the 'springs M2, which press against the backs of the rods M. The lower portions of the rods M extend below the -bifurcated frames M3 and are formed into inwardly-extending arms M2, the arms M2 and frames ill being connected by suitable shuntwires m.

The device is operated as follows: The block A is suspended upon a suitable support, as described, and to raise the hood and lamp the operator pulls upon the free end of the cord C, and thus raises the hood: The bar H will enter the lower opening A2 of the block A, and the hook H' will pass between the springs Z) and hook a', and the hook H of said bar will engage the hook a', thussuspending the hood. To release the hood, drop the lamp out of the hood, as described below, then draw it back, keeping the rope tight, which will hold the rod M against the slide J, and raise the suspendingbar H till the hook I-l passes through the opening b2 between the members of the spring b, and the cord C is slackened. The hook H will then drop upon the beveled portions b. of the springs b and will be thereby guided by the lugs hfthrough the lower opening of the block; The hood being heavy, it is necessary to pull harder upon the cord to release the hood than to release the lamp. The hood being suspended, as described, and the lamp being lowered, the lamp is suspended in the hood as follows: By pulling upon the free end of the cord C the rod G, socket G2, and the lamp suspended therein will be raised, as described. The upper end of the rod G will enter the sleeve F and the lug G will enter the slot F2 of the sleeve F', thus `'bringing the lamp -conneetious into their proper positions. As the rod G is raised, the ends of the rods it pass between the members g2 of the plate g and come in contact with the lower ends of the slide J and stop J4, thus preventing the lamp from being raised farther. The cord C is then slackened and the hooks M drop upon the hooks L', thus suspending the lamp. rlhe slide J and stop J* will then resume their normal position, and to release the lamp the operator pulls upon the cord C, as before. The ends of therods M pass upwardly through the opening g of the plate g, and when the operator slaekens the IOO IXO

cord C the laterally-projecting sides of the descending hooks lll strike upon the beveled portions g3 ot the plate g, and the hooks M' are thereby prevented from engaging upon the hooks L', thus allowing the lamp to be lowered.
