RFLECTE ATTHIJIENT.

peceaton of Letters Patent.

,To all whom 'it may concern.' I Be it known that l, HENRY DlOLinR, Jr., a l citizen of the United States, residing at,l Rutherford, in the State of New Jersey, beve invented certain new and useful improve` ments in Reflector Attachments, of .which the following is a` specification.

My invention relates to reflector attach- 1nentsan`d particularly for use in connection 'with elect-ric glow or incandescent lamps.

While it has been quite connnon to attach a reflector to an electric incandescent lanip, the attachment hes been made without duo regard for the position of the reflector surface with respect to the light emitting source,

with resultantpoor economy in the distribution of the reflected light. x

it isthe object of Inr invention to provide l a reflector attachment for electric lamps l which shall combine with siniplicity,.chcap ness and durability, the function of adjust` l `ing the reiiector With respect to the source ot' light` so that different distributions of light, Within Wide limits nitty be obtained, and so that it shall be possible, irrespective of differences in dimensions of socket, lamp, reflector,` or other parts, that the reflector may be adjusted after .it has been attached to the lamp fixture to that position with respeel; tothe light eniitting source which shall' l produce the inost ciiicient reflection, either to secure greatest concentrations of reilected light, or desired dispersion. To this end l l provide an attachment for the reflector l which allows the reflector to be adjusted longitudinally with respectto the lamp or l socket. l

My invention resides in the structures hereinafter shown and described.

For an illusration of one el the forms my invention may take,l reference to be l had to the accompanying drawing, in which Figi'ire l is an elevational' View of u lamp l socket with tie relleelor supported thereby and adjustable longitudinally, the reflector :ind theisupporting and adjusting means being shown in vertical section. f3 is an elevational View of one oit" the aduster inenil bers. Fig. 3 is au elevational View of l another of the adjuster members. l

Referring to the drawing, a lamp cord (l, or other suitable flexible or rigid support, disposed vertically, or at any other angle, supports a .lamp socket S, which may have ,I

flange lli', the reflector or shade the usual lrcy K, here shown one of the standard sockets' used at present sind having ai bead Z) approximate its lower end. lnto.

the lump socket may be fitted :in incendes cent lmnp L shown in 'dotted lines to indi.Y cate the position a lamp nia i take. A resilient ring` member E, circuinerentially discontinuous, is provided with e bead c adopted to sprino' over and register with the lamp socket and bead o, and aboveA this heady c the edge :of the ring lt is tin-ned over, as at d, to hold the resilientm'f'ire ring c, also circuinerentially discontinuous. This resilient ri e reinforces or stii't'ens the ri ineniber lt' causing' more secure a technient between :ingl and-the lomo socket. i-it some distancebeloiv thebe shoulder It is pro ided te forni between and the lower lip or flange o' a deep substantially flat sided'groove to receive the turnedin edge of the upper adjuster nienr ber fr. y

rlhe uster member it is preferably cv4 lindrical in forni and is adapted to ht inside of the lower adjuster member, t' having steep shoulder formation j add the lip or niernber n, having the inside reflecting surface n', beine' received and held between the shoulder und the lip On the adjuster inernber it is o. teat or pro jeetion Z adapted to enter end more in the spiral groove or heed m on the inside oit the adjuster ineniber The resilient niember R is snapped .into and eXLnnds/in the upperaperture in the adjuster member/iJ and, 'the ring R inay then the position shown, the bean with the socket bend o,

To raise er lower the rel-lector n, so es to bringsr its reflecting surface ft to critical or desired height with respect to the lighteniitting' source ol `the lmnp L, the lower adjuster member t' is rotatechas by thuinl" and finger, causing,` the member z to nieve upwardly and downwardly upon the inein-` ber le, due to the action of the groove m, upon the projection Z. As shown in the drawing, therellector n, is in its lowerinost position, but it may c registering be raised a considerable ldistance by the action 'Just described.

ad c a steepbe snapped. intr icc lllhile the engagement oi'' the lip upon the lamp L may limit the downward travel of the reflector n, such downward travel .may be limited by a stop 0 on the member t uster memberI 7L.

engaging with the turned-in top of the ad- Aftcr the member 71. has been entered into the member fi, the stop 0 is bent from the straight position shown in Fig. 3 to the position shown in Fig. l.

it will be noted that the adjuster member z' has a relatively large opening at its lower end, thus forming a wide mouth, to permit the parts to assume as low a position as shown with respect to the lainp.

iVhile I have here shown the projection and groove as means for securing longitudinal movement, it is to be understood that any other form of telescopic or longitudinal movement ot the parts la, and z' may be em ployed.

lt is preferred that the ringy member R, the adjuster members L and e', and the reyHector or shade member n, be made of sheet metal, such as brass, iron or steel, being brought to form by spinning, by pressing in dies, or by any other suitable process.

` From the foregfging description, it is apparent that I have provided an attachment for a reflector to an electric lamp fixture which permits thereflector surface to be adjusted within relatively wide limits longitudinally with respect to the lamp or socket.

rThe reflector n .is here represented as being a surface of revolution with its axis substantially coaxial with the socket and lamp axis. It is to be understood, however, that other forms of reiector may be employed, and thatthe adjuster member may be attached to the retiector member at an angle with the axis of the reflector instead of coaxial as shown. In such case, the axis ot the reflector would be at an angle with the socket axis, and the reflector may be rotated around the socket axis, such move ment of rotation occurring either at the groove between the shoulder and the lip c or by the rotation of the member L upon the ring R at the groove between the steep shouldered bead f and the lip g.
