intersecting paths by providing improved resilient clamping means which is adapted to :maintain frictional engagement between the fixture andthemounting therefore so .asto enable said vfixture to be positioned at any convenient location along its path.

Another object of my present invention is to provide a shiftable electrical lighting fixture in which the electricalvcircuit'may be maintained during the shifting of a light withoutnecessitating the use of flexible conductors and the like, and to'this endT propose to provide a'contact element along which the lighting fixture may be moved.

. Referring to the drawings more particularly, I have? illustrated and described my invention as adapted to a cabinet 7 of the bathroomtype provided with a hinged'door carrying a mirror. I It will beapparent that-the mounting ofthisinvention might be adapted nto: various other purposes. This cabinet 7 is provided with the usual body having shelves LStherein and a door 9 mounted on hinges "11 ;;to swing to: open and closed'position; The

rear of the cabinet is provided with an open- :ingi1l2ithrough. WhlCli passes electric WlIlIlg 13 connected to a source (not shown), of electrical current. This wiring 13 is led through a tubular guard 14 to a compartment 15 formed between the front of the door 9 and a partiti on 16 carried thereby in inwardly spaced relation. This guard is pivotally mounted for horizontal swinging movement on a vertical pin 17 attached to the door within the compartment 15 and extends through the front wall 18 of a small compartment 19 in the upper end of the cabinet and the partition 16, suitable openings being provided therefor in said wall and partition. The wiring 13 after passing through the tubular guard 14 passes outof an opening 19 for connection to a movable fixture 21, suflicient slack being provided in said wiring within the compartment 15sothat said fixture may be moved, as will be hereinafter described,without impairing the connection. The guard 14 acts to protect the wiring during the opening and closing movements of the door to thereby prevent the wiring from being caught or pinched during such movements.

The door of the cabinet is provided with'a 'mirror 22 and the fixture 21 includes an electric lamp 23 adapted to illuminate the face of a person before the-mirrorand enable the mirror to reflect an image of the face thus illuminated. The lamp is mounted so that it can be conveniently shifted along the margin of theinirror into various positions of adj ustment to facilitate persons of various heights seeing themselves in the mirror and to facilitate a person seeing any desired'portion of lllS face more clearly. In this embodiment the lamp may be shifted vertically along the margin of the mirror frame on either side thereof or horizontally along the margin at the bottom of the mirror frame, the vertical axis of the lamp being rigidly maintained at all times. i

To that end I provide a slotted track24 extending from a position midway up on the margin of the mirror frame at one side thereof downwardly to a lower corner of said frame horizontally across the lower margin of said frame to the opposite lower corner and upwardly to a corresponding position on the other side of said frame. This track 24 includes vertical guide- ways 25 and 26 which intersect a horizontal guide-Way 27 at its respective opposite ends. The guide- ways 25 and 26 are provided with a vertically elongated slidable carriage 28 and 29 respectively.

slidable carriage 31 is capable of sliding directly in the guide-way27 and of being car ried by the carriages 28 or 29 in their respec-' tive guide-ways. The carriage 31 rigidly supports the fixture 21 including the lamp 23 and comprises an integral outwardly extending sleeve 32, the outer end of which is screwed in. an, angular'ly disposed lamp fitting 33 which together with the lamp 23 and a socket 34 at the upper end of said fitting forms the fixture 21. The wiring 13 passes from the compartment 15 through the sleeve 32 and the fitting 33 to the socket 34.

As the fixture 21 is moved horizontally in the guide-way 27 the upper and lower sides of the carriage 31 co-operating with said guideway will maintain the axis of the lamp 33 vertically. The lower portion of each of the carriages 28 and 29 is cut away to receive the carriage 31 which is of considerably less thickness than either of said first mentioned carriages. The carriages 28 and 29 are each provided with a horizontal guide 35 adapted to extend into a co-operating groove 36 in the carriage 31 to maintain the latter in horizontal position at the intersections of the horizontalguide-way with either of the vertical guide-ways to thereby maintain the vertical axis of the lamp at this intersection and assure alignment of the carriage 31 with the carriage 31 iscarried by either of said first mentioned carriages. Without the vertically reciprocablecarriages 28 or 2 9 the carriage 31 when at either end of the guideway 27 preliminarily tobeing moved up- Wardly in one of the vertical guide-ways'or preliminarily to being moved from one of said vertical guide-ways into the'horizontal guide-way would not be rigidly held'in horizontal position to thereby rigidly maintain a vertical axis of the lamp and assure alignment of the carriage 31 withjthe guide-way in which'it is desired to moveita For this reason the carriages 28 and 29 greatly facilitate the transfer of:the carriage 31 from the horizontal guide-way to either of the vertical guide-ways or vice versa and thereby enable the lamp fixture to be more conveniently adjusted.

Surrounding the sleeve 32 is a coiled spring 39, the inner end of which engages a circular shoe 41 also surrounding said sleeve and disposed between the fitting 33 and the track 24. The outer end of this spring 39 engages the bottom of a recess 42 formed within the fitting 33 for the reception of said spring and the inner end'of said spring yieldingly holds the shoe 41 against the track to thereby automatically maintain the lamp fixture 21 in adjusted position.

Referring now to Figure 7. it will be seen bushing 44 is a yieldablecontact finger 46 which is yieldably maintained in contact with a suitable contact strip or bus bar 48 through the agency 7 of a suitable coiled spring 50. The contact finger 4:6 is electrically connected with and housed within a metallic sleeve 52 which is connected to the terminal of a conductor 5a, which conductor is connected with the lamp proper. For purposes of more clearly 'llustrating the arrangement of the device, the lamp 23 is shown diagrammatically. is grounded through the lamp frame 33 and the door frame 9 as clearly shown in Figure 7. It will thus be apparent that the lamp fixture may be moved from one position to another within the passageways without disrupting the contact between the finger 46 and the contact strip 48. I

It will be apparent that my invention is applicable to mountings other than the specific cabinet mounting also be understood that my improved mounting enables a lighting fixture to be adjusted from one position to another through an angular path of movement with a minimum amount of effort and there will be no tendency for the fixture to wabble. In other words, the fixture in moving from one path to another, cannot oscillate about its axis and the carriage members also assure the proper alignment of the fixture when shifting from one guide-way to the other. In my co-pending application Serial No. 190,538, filed May 11, 1927, relating to wall cabinet,I have disclosed a shiftable lighting fixtureofthe type which may be readily equipped with carriage devices of the design disclosed in the present application.
