. siicl'i mbiii'itiiiglfineans is of'the same-construcof aiding in further destriptioiifha've been niii'n includes an outer wall 42, a relatively long edge wall 43 and a shorter edge wall 44.

The lower ends of the edge walls of the guides are disposed on the outwardly directed portions 36 and 31 of the mounting means and rivets 'or other securing means 45 serve to secure such walls to the upstanding portions 38 and 39 of said mounting means. Wall 42' of'each guide has a slot 46 opening through the lower or inner edge thereof. Mounted in the guides 40 and 4| are carrier 41 and 48 respectively (of identical construction but separately numbered for the purpose of further description).

Carrier 41 is shown alone in Fig. 10 and there it will be noted that the same includes a bottom wall 49, an outer or'rear wall 50 and side walls A perforated ear 52 is secured to the underside of the carrier in any suitable manner and may infact be formed'by lancing and pressing a piece from the bottom wall 49 of the carrier.

The carriers 4'! and 48 are 'shiftable in the guides toward and from the open outer or upper ends of the latter. Edge walls 43 and 44 of the guides have their forward edges bent inwardly to provide flanges 53. located parallel with the rear walls 42 of the respective guides. Thus when the carriers are located in the guides their movements toward and from the open upper ends of the guides are controlled and guided by the side walls 43 and 44, rear walls 42 and the flanges 53.

Toggle means are provided for shifting the carriers in their respective guides. 54 is associated with carrier 41 and a similar or identical toggle 55 is associated with carrier 48. Each toggle includes a lower link 56 having its lower end located between the arms of the bent portion 32 of its mounting means and anchored by a pivot pin 51. Upper link 58 of each toggle is' pivoted at its upper end to the car 52 of its carrier as by a pin 59.

An operating link 60 of each toggle is pivotally connected at its outer end'with the upper end of link 56 and the lower end'of link 58 by a pin 6|.

Slots 62 and 63 may be provided in the end portions of the bar 24 through the upper and lower portions thereof for the accommodation of the various links of the toggles. A spring 64 is associated with each toggle 54 and 55 and'each such spring has an arm 65 bearing against a toggle link 56 and an arm portion 66 hooked over the- Thus toggle 10. When the arrangements are as described there is a slight reserve motion available to give the lamp and its end socket portions an extra movement when such may be made necessary by and 68 respectively carried toward one another through the tubularbar 24 and after passing over pulleys 30 and 29 respectively passing downwardly through the handle 23 and out through the lower end thereof. These ropes provide means for operating the toggles to straighten their normal positions.

While the arrangements may be such that the ropes operate the toggles to or even through a dead-center position it is preferred that the movement stop short of dead-center when the device'is being used to mount lamp 1'! on fixture a variation in the size of any parts employed.

Further when the toggles are not actuated to a dead-center position the springs 64 may function to return the toggles and the carriers to their normal position.

Carried by the bar 24 and fixed in predetermined relation thereto and to the guides 40 and 4| are a pair of locating or aligning pins 69 and 70. These pins are mounted as by straps H bent about the bar and having their end portions 12 perforated and arranged in close parallel relation. Screws 'l3 passing through such perforated end portions are threaded into the lower ends of the pins and on being tightened cause the strap to grip the bar and in addition attach the pins to the straps and thus the bar. Preferably each pin 69 and 70 toward its outer end is pointed or bullet-shaped as a 14 and inwardly of such and is notched to provide an inwardly facing shoulder '15.

Socket bases H and I2 are mounted on the bottom or inner wall of the fixture l0 and each base includes a neck portion I6 passing through such wall and having openings therein for the reception of the contact prongs l8 and [9 of the plugs l5 and Hi. The mentioned wall of the fixture is designated' 1'! and in such wall are a pair of holes "18 spaced apart as are the pins 63 and 10 and bearing approximately the same relation to the entrances to the bases H and 12 as do the pins 69 and 10 to the prongs l8 and I9 of the plugs 15 and 16 when the latter are located in the carriers 41 and 48.

Thus when lamp H is to be mounted on fixture It the plugs l5 and 16 are mounted on the respective ends of the lamp. Thereafter such plugs are disposed in the carriers 41 and 48 with the lamp now supported by the plugs and carriers as shown in Fig. 1. At this time the carriers are in their lower or retracted positions. Now the extension means is raised and the ends of the pins 69 and 10 introduced through the holes 18 in wall ll of the fixture. A slight lateral movement of the extension hooks the shoulders 15 on the pins over the edges of the holes as shown in Fig. 5. Now the prongs l8 and I9 are aligned with the entrance openings to the bases H and I2.

The operator straightens the toggles, as by pulling the ropes 61 and 68, and the carriers 41 and 48 are shifted upwardly in the guides causing the prongs of the plugs to enter the bases II and I2. The shoulders 15 of the pins 69 and 10 being hooked over the bottom wall of the fixture the parts do not move downwardly as the ropes are pulled and so the carriers are moved upwardly moving the contact prongs into the bases of the sockets. Only a simple rectilinear movement of the carriers and the socketed lamp is involved.

When the prongs are home the extension means is given a slight lateral movement to take pin shoulders 15 off the wall ll of the fixture whereupon the entire extension means may be lowered leaving the lamp mounted on the fixture. The described lateral movement of the extension means would be toward the right as the device is viewed in Fig. 5 although at the de scribed time the parts would have been moved to the positions of Fig. 6 and thereafter the caraaaman r riers-wouldhaveibeen moved7back.to:theinnormal positionby thespringsrfl. Thus-Zatthatime: of. therdescribed lateraln'oove-- ment of: the: extension. means the carriers are in their. lower. or. retracted positions. and the open upper side edges of the guides 40 and 4|, thespor tions above the short. walls 44 comprising such openupper side edges, are" opposite the edges.-

of the plugs-.- Thus' the extension-'may be'shifted. laterally; leaving. the plugs connected with the bases andisupporting the lamp.

It will be: understood that, the device of:the' invention may; be-provided'in various sizes to re- I ceive the. variouslengths: off fluorescent? lamps,

The relationship; of the; parts is such that when the-plugs: are on; the ends. of alamp such plugs may bereceivedin the carriers-41 and of the. device.
