Specification of Letters Patent.
Application filed August 31, 1912. Serial No. 718,088.
Toall whom it may concern:
Be it known that I, KNUT :RUDY, a subject of the Kingof Norway, residing at New York city, in the county of New York and State of New York,:have invented new and useful Improvements inLamp-Brackets, of which the following is a specification.
This invention relates to electric .light brackets and more particularly to an adjustable bracket of this sort used by dentists and others, requiringa lamp to be held in a certain adjusted position.
The object of the invention is to provide a simple and cheap device of this character that may be readily attached to a wall or support and capable of wide adjustnientto yarious degrees of angles.
To these ends the invention consists in the novel details of construction and combination of parts more fully hereinafter described and particularly pointed out in the claims.
Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all the views :Figure 1 is a side elevational view of my improved bracket secured to a wall or other support. Fig. 2 is a cross sectional view taken on the line 22 of Fig. 1, and Fig.3 is a cross sectional view taken on the line 3-3 of Fig. 1.
Secured to a wall 1 or other support, are two oppositely disposed brackets 2 provided with bearing portions 3, within which are adapted to be secured trunnions 4 ifor supporting a fitting 5, Whichfitting is provided with a segmental portion 6 having a segmental rack 7. Pivotally connected by a pin 8 to the segment 6, is an arm 9, which arm is provided at its inner end with a pawl 10 normally held in; engagement with the segmental rack 7 by means of a spring 11, which spring bears at one end against a shoulder 12 on the pawl 10 and at. its other end against a shoulder 13 on the arm 9.
This arm9 is adapted to beheld and locked by means of the pawl10,in.various adjusted angular positions on the segment 6. j
The pawl is released by means of a rod 14; pivotally connected as. at 15, to a trigger 16, which trigger is pivotally connected as at 17 to the arm 9 and is adapted to be operated within the slot 181cut on the lower portion of the arm 9. Afitting 19 is secured to the outer end of the arm 9iand is provided with opposedbearings 20 within which is pivotally held a tapering pin. 21, provided at its lower end with a screw threaded portion 22 and at its upper end with an enlarged head or bearing portion 23.
Fitted in this head or hearing portion 23 and adapted to beheld at right an les to the tapering pin 21, is a pin 24 provicl ed on one end with a socket 25 and on its other end with a screw threaded portion 26 on which is secured a claim screw 27 provided with a handle 28, which screw is adapted to securely hold the tube 29 in any adjustedangular or universal position. The tube is also slidably mounted within the socket 25. 'Onthe electric lamp socket 32. The lamp cords or wires extend through the tube 29 and are connected to any suitable source of electric supply (notishown).
spr1ng33 mounted within the tubular portion 34 of the vertical adjusting nut 35, is
adapted tonormally hold the tapering pin 21 carrying the lamp tube 39, in any ad justed horizontal position. Thetension :on this spring 33 is normally increased and diminished by the adjusting nut 35, as is clearly shown in Fig. 2.
From the foregoing it will be seen that by the construction of a lamp bracket in accordance With my invention, persons such as a dentist or others, may be able to adjust features except as may be required by the.
What is claimed as new is:
1. In an adjustable lamp bracket, the combinationof a suppcrt, a segment pivotally mountedlon the support and capable of horizontal: adjustment, an arm plvotally connected at its inner end. to the segment and capable of angular adjustment and a tube pivotally connected. to the outer end of the arm .andarranged for universal adjustment.
2. In an adjustable lamp bracket, the combination of .a support, a segment pivotall mountedlon the support and capable of hor1-.
Patented Apr. 15,1913.
outer end of the tube 29 is held a bushin 30 to the reduced end 31 of which is secured an nected at its inner end to the segment and capable of angular adjustment,
mounted on the arm and coacting with the segment forlocking the said arm in anadjusted position, and a tube pivotally connected'to the outer end of the arm and arranged for universal adjustment,
3. In an adjustable lamp bracket, the combinationof a support, a segment pivotally mounted on the support and capable of horizontal adjustment, an arm pivotally connected at its inner end to the segment-and capable of angular, adjustment, means mounted on the arm andcoacting with the segment for locking the said arm in an adjusted position, a tubepivotally connected to the outer end of the arm and arranged for universal adjustment, and means mounted Copies of this patent maybe obtained for means I on the arm for holding the tube in an adjusted position substantially as described.
4. In an adjustable lamp bracket, the combination of a support, asegment mounted on the support, a segmental rack mounted on the segment, an arm pivotally connected at its inner end to the segment, a pawlm'ounted 0n the arm and arranged for coacting with the rack for holding the arm in an elevated position, a tube pivotally connected to" the outer end of the arm, and meansfor holding,
the tube in any adjusted position. In testimony whereof; affix my signature in presence of two witnesses.
