AUTOCLAMPING LAME GR1} Specification of Letters Patent. Patented 31 21 1922 Application filed July 12, 1920. Serial No.395,773L

'0 aZZ w/zom 2'15 may concern:

Be it known that I, VAL1ER Gr. Womn, a citizen of the United States, residing at San Pedro, in the county of Los Angeles and State of California, have invented a new and useful Autoclamping Lamp Guard, of which the following .is the specification.

My invention relates to combined guard and reflector or shade for eleotric lamps.

An important object of my invention is to provide a combined guard and shade or reflector for electric lamps having improved automatic clamping means to permit of the ready attachment to, or removal from the socket commonly employed with electric lamps.

A further object of the invention is to provide a device of the class described which is simple, neat in appearance and cheap t0 manufacture.

In the aceompanying drawing in which like reference characters indieate like parts thronghout the several views,

Fig. 1, is a front elevation of my device showing the parts in assembled relation.

Fig. 2, is a side elevation of Fig. 1,

Fig. 3, is a front elevation of my shade or reflector with guard or gate removed.

Referring to the drawing in detail, 1, indicates a shade or reflector with the sides, 3, bent at angles terminating at its rear or socket end. in a constrncted curved resilient split neck portion, 2.

The shade or reflector is further provided with perforations, 15.

The neck, 2, of the shade or reflector, is bent at its open ends to form wings, 4, which are provided at diametrically opposite points with bores or holes, A, throngh which bores or holes, a rod or bolt, 5, is inserted, said rod acting, as a pivot on which the semibulbous shaped guard or gate portion, E, is adapted to swing into opened or elosed position. and also aots as a means whereby the device is held together in its entirety.

The neck, 2, is further provided with wedge shaped portions, D, D. plaeed adjacent and in close proximity to the holes, A, the purpose of which will be explained later.

The gnard or swinging gate, E, is bent into a shape. more or less resembling a horse shoe, having the forward portion flattened and the side frames, 7, 8, longitudinally curved, and horizontally curved Wires, 14 spaced equidistant apart.

The longitudinally curved side frames, 7, 8, converge toward the'center terminating 1H enlarged rear end portions, C, C,said portions, C, C, being provided with bores or holes, 12, 12, and said b0res orfiholes being out of line with the radial Center of the szud end portions, C, C. A

The rear endportions, C, C, being en larged and mounted' 'eocentrically, will always present a bearing' surface to wedge shaped portions, D, D,-and the gateis swungto .elosed Or operative position, said ends, C, C, acting on*the'vvedge"shaped port1ons, D, D, will tend to draw the neck, 2, into frietional engagement with the lamp socket.

Up0n'inward movement of the SWinging gnard or 'gate,"E, to locke;d position the enlarged'a'ndecentrically inonnted ends, C, C, of the fra'me members, 7, 8, slideonthe wedg shapedfacs of the portions,'D,D,

traveling toward the higher partofsaid wedge shaped portions, D, D.

This tends to contract the neck, 2, and bring it into frictional engagement with the lamp socket, which engagement looks my device into secnre position.

Upon ontward movement of the guard or gate. E, to open position the ends. C, C, ride toward the smaller parts of wedge shaped portions, D, D. thns allowing the neck t0 sprmg open. and disengage itself from the lztmp socket. Which will permit of the ready removal of the lamp or the device as a whole.

The forward and of the shade or reflector, 1, extends a short distance beyond the upturned sides. 3, and is turned over upon itself. or beaded. as at, 13. thus providing a shoulder over which the forwaid and flattened portion of the hinged guard or gate, E. is snapped when the device is in use.

In the practice and use of my invention the gnard or gate, E. is moved ontwardly on its pivot to permit the socket to be inserted into the neck portion, 2.an electric light bnlb is then screwed, or otherwise fixed into the socket.

The swinging guard or gate, E, is now swung into closed position the eccentrically mounted ends, O, C, pressing against the faces of the wedge shapod portions, D, D, which causes the neck, 2 to oontract and fritionel1y enaa the lampsoclt.

This provides 'a quick and secure means of holding my device in operative position.

When it is desiredtoremovea globe the hinged guard or gate, E, ismerely released from the retaining bead, 13, and plled outwardlythis Will permit of the takin out and the ready insention of a new glo or the removal of the devicea3e wholet In usin the device in connection with dm y cor lighte, extensions or portable cor s employed in shops, garagesand other places, the shade or rflecton, l, serves to otect theey-of the user, and also directs The hinged guard on gate, E, together Withthenkade on reflector, l, serves to protect the .f;onaccidentel fracture.

, Thmpfomtions,,l, provide for ventilatvi0fl'L 4 Hwin flans deaer-ihed my invention, what I o aim is 1. 'Ighe combinatfinnwith a reflector, having wec}fing sunfaces, of mcane pivoted to saut ne octet and forming an actuating engagement with. scid wedging surfaces,

{un oausjng dumping, contraction of said 2. The combination with a rcfiector of a guard pivoted to the same, and means actuatedby said guard for securingthe device in position.

3. The combination with a reflector having a split neck, 0f' Wedging means upon the ends of said neck, a guard adapted to engage said wedging means so as to restrict sid neck and secure the refiector in position.

4. The combination with a refieetor having a split neck,of wcdging members upon said neck, and means eccentricaliy pivoted to said refiector and adapted to engage said x vedging members-so as to restrict said neck and secure the reflector imposition.

5; Thecombination with a reflecto1 having a split neck, of wedging members upon seid neck, and a guard for said refiector havdng arme. eccentrically pivotedt0 the re fiector at snid neck, said arms being adapted to engage seid Wedging members so as to restrict seid neck and secure the reflector in oted to the same at s'aid neck, said guard and neck co-operating toi restrict the. neck by the swinging movement of the guard.

In testimony whereof I have, signed my name.tothis specific&tion in the Presence of two su bscribing witnesses.
