a ii'catip fiiea-ma si, 1921. "Serial No. 473,763.
To all whom it may concern- Be itknown that I, JAsoN, C. STEARNs,;a citizen of the United States, residing at Worcester, in the county ofWorcester'a'nd State of Massachusetts, have invented'a new and useful Spotlight Support, ofwhich'the following is a specification. I p v This invention relates to a "bracketand other supporting elements, for ajspotlight. The principal objects of the invention are to provide a simple and inexpensive device for .carrying an adjustable spotlightand' attaching it to the wind shieldfra'me of the'vehicle, preferably, and especially to provide A an improved bracket and improved means by which the spotlight is'detachably'a'nd yet "firmly mounted on "said bracl zetfand con nected' therewith. j 7
Further objects and advantagesof the'invention will appear hereinafter.
Reference is to be had to theacconipanyo ordinary structure;
Fig. 2 is' a sectional view on an enlarged tion showin it as supporting'a spotlightof scale on the line-2+2of'Fig. 1; I
Fig. 3 is a front elevation of the bracket; Fig. 1 is a plano'nian enlargedf'scale'of a modified form of bracket and supporting 1 same on the line 55 of Fig. Land Fig. 6 is an elevation ofthe pivot pin therefor. p
In the form shown in the firstthree figures a spotlight 10 of ordinary construction, having anoperating handle 11 is shownand, as usual, provided with a hub 12' which has means by which the lampis pivoted on'the vertical frame 25 of the wind shield. In the present case this hub has two ears 13 spaced apart for receiving a bolt or screw 14 through them. This bolt also passes through a flat end 16 of a pivot pin 17. Thus the lamp'is pivotally mounted on the end of this pinto swing on a transverse axis the pin being Fig. 5 is an enlarged sectionalview or the end a pair of spacedclawsor j aws QLQ On this platejismountedja clamping plate 22 'havinga corresponding pair of cflaws'23. Screws'24 are provided for attaching the two plates together and clamping the twosetsof claws "on a] verticalrodj 25 orthe flikefon "which the wholede'vice is supported. The plate*22 is p cua1 1 pivotea to the plate 20 on the screws2lsothat by tghtening them up the bracket becomes a fixed structure.
at 26. This"perforation;extends through the end; of the plate 22. The plate 120] isjprovided with a third plate 27"secure'd to it "by screws'28 and having a flexible "steel bar 29 under the heads" of thesetwo screws to; p reis substantially circular mpress-section in the form shown but on account er its'being length of the passagefor receiving the proections 19-when thela'mp is turnedto' the ri 'ht position. Only one 'of thesegrooves is "necessary it only one pro ection'l9 is used and I have shown'one' of them as formed too small to allow the? projection to "pass through it. y I
In this construction *the' screws' 24 are tightened up .toclamp the claws21and"23 against the opposite sides ofthe fixed rod 25. l
The lamp withthe pin l'zprojecting from it is usi1ally**used*and* the projection 1 9 can be inserted in-its gro'ovebO. *T-hen the 3 lamp is pushed in nntil; the collar 18 rests on end of the bracket and the'projection 19 is in the space 26. Then the lamp is turned quarter way around and the long dimension of the pin 17 just fits frictionally in the passage formed between the two plates 20 and 27. Thus the pin is held frictionally either in position exactly forward or backward or at any angle except a vertical position substantially at right angles thereto. The projections 19 furnish positive means for preventing the removal of the lamp. \Vhen it is to be removed it is turned to the position at right angles and it can then be drawn out without trouble.
In the form shown in Figs. 5 and 6 acircular pin 17 is shown having a longitudinal depression 32 throughout its length "for receiving a wedge as on the bracket. The pin has a reduced end 3 which is widened out on the opposite sides to form two projec tions 89 having flat surfaces. T his forms a convenient way of making these projections without changing the shape of the main portion and it can be made to lit trictionally in all positions.
It will be seen that in either form the lamp is not only capable of turning on horizontal axis, but is also arranged to turn on a vertical axis and be held locked in position so that it cannot be drawn out ol? the bracket as long as it is being used for the ordinary purposes of a spotlight. The (on struction of the bracket and pin in either case is simple and inexpensive.
Although I have illustrated. and (lSC]llJGfl only two forms of the invention I am aware of the fact that other modifications can be made therein by any person skilled in the art without departing from the scope of the invention as set forth in the claims.
Therefore, I do not wish to be limited to all the details of construction herein shown and described but what I do claim is 1. In a spot light bracket, the comliiimition with two sheet metal plates each having a pair of curved claws for clamping the bracket on a rod, of means arranged with their centers in a plane parallel to the axis oi the rod for holding the plates and the claws together, one of said plates terminating short of the other at the other end, and. a third plate removal'ily attached to the longer plate beyond the shorter one. the third plate and the longer one ha; L cylindrical passages const-itidinp; meam ,l'or pivotally supporting a spotlight on an transverse to the axis of said rod.
2. In a spotlight support, the combination of a bracket in two parts, each having;- a set oi jaws, means for clamping said jaws on opposite sides ot. a supporting' element to hold. the bracket, said bracket having j sage therein of a general circular shape and a groove along one side thereof, and a pin fitting in said passage for supporting the spotlight, said pin having a radial projection at its end adapted to enter said groove and extend under the end of the part of the bracket in which said passage is located.
3. In a spotlight support, the combination oi a bracket having a passage therein of a general circular shape and a groove along one side thereof, and a pin fitting in said passage for supporting the spotlight, said pin having a radial projection at its end adapted to enter said groove and extend under the end of the part of the bracket in which said passage is located, said pin and passage fitting each other ti-ictiouall' when the lamp is turned to longitudinal position and loosely when the lamp is turned to a transvene position.
4:. The combination with a spotlight, o'l a pin to the end of which the spotlight is pivoted, said pin having its front and rear surfaces formed on the arc of a circle and its side surfaces at a shorter distance apart and provided with a radial projectioiii at its end, a b 'acket having a D2151. ige open at the end for said pin and having a groo 'a along the passage for said projection which extends into the opening at the end ol said passage, and means l'or clam ping the brai'ket in fixed position.
5. The combination with a spotlight, of a pin through the end oi which the spotlight is pivoted. on an axis transverse to ti 2 axis of the pin, said pin being of an. approximately round shape but having a longer diameter in one direction than in the transverse direction and provided with a radial projection at its e'r-itreme end. with a bracket having a passage as long as said pin back of said projection and open at the end to receive the pin and haying a groove on it through which said projection is adapted to pass when the pin is lILBQT'lJUl, whereby the projection will be received beyond the end ol? the passage and in'evenl, the removal of the pin when the pin is turned after being inserted.
In testimony whereof I have hereunto al fixed my signature.
