,QTTORNEY United States Patent Office 2,723,343 Patented Nov. 8, 1955 This invention relates to a combined lamp bulb guard and reflector of the type adapted to be utilized in conjunction with a portable lamp bulb holder for directing light to a selected location, such as a part of a mechanism being worked upon, and at the same time protect the bulb from damage.

It is a primary object of this invention to provide a unitary guard and reflector structure, thus obviating the necessity for separate guards and reflectors, such as heretofore has been the case and wherein the guard assembly need not be disassembled or removed from the holder or handle to remove or replace the lamp bulb.

7 It is another object of the invention to provide such a device which may be readily applied to and removed from a light bulb as desired.

It is still another object of the invention to provide an integral structure of this nature which has a hook, whereby the same may be suspended in any desired location.

It is still another object of the invention to provide such a device which requires a minimum of parts, and which may be assembled and manufactured with a minimum of expense and difliculty.

It is a further object of the invention to provide such a device which may be readily utilized with a variety of sizes and shapes of light bulbs.

It is still a further object of the invention to provide such a device which will serve effectively to protect the lamp bulb against damage, and which will at the same time serve eifectively to direct the lightin the desired direction in accordance with the relative position of the reflector member.

It is still another object of the present invention to provide a lamp bulb guard of the type described which is simple in construction, durable, which is effective for its intended purposes, and whichcan be manufactured and sold at a reasonable cost.

Referring now to the drawings in detail, the combined bulb reflector and guard of the instant invention, generally indicated at 10, is comprised of a reflector half 11 and a guard half generally indicated at 12. Referring first to the reflector half 11, the same is comprised of a shell of generally elongated semi-spheroidal shape, including at its top portion a recessed rim 13, terminating in a flat circular plate or tab 14, in the center of which is swivelably mounted a hook 15 of conventional type for the suitable suspension of the device and its associated bulb from a suport. Extending peripherally about a por ,tion of the rim of circular plate or tab 14 opposite reflector shell 11 are a plurality of holes or apertures 16, the

purpose of which will be more fully pointed out hereinafter.

The lower portion of reflector half 11 is externally indented or recessed as at 17 to form a semicircular band or locking collar portion or member 18, provided on the ends thereof withoppositely projectinglugs 19, which in turn are provided with suitably threaded bores for the reception of screws 20. The lower portion of reflector half 11 has turned inwardly and upwardly two

resilient tabs

17 and 17 adapted to engage a shoulder of the handle or holder to align and retain the device 10 against outward axial displacement from the handle or holder.

The screws 20 are adapted to engage corresponding threaded bores in lugs 21, which comprise the extremities of a semicircular band or locking collar member 22, that is a portion of guard half 12 of the device. Guard half 12 is comprised of any suitable number of vertically extending wires 25, in the illustrative embodiment there being shown only four of these wires. The guard 12 is generally of the same elongated semi-spheroidal shape as the reflector and will close into opposing relationship thereupon. Vertical wires 25 are suitably secured in any desired manner, as by welding 26 at their lower ends to semi-circular locking collar member 22 and extend upwardly and outwardly in order to embrace a lamp bulb 31, and thence inwardly as at 27. The upper extremities terminate in relatively loose loop portions 28, that are passed through the apertures 16 in circular plate or tab 14, in such manner as to form a hinged connection thereto, and in a manner and for a purpose to be more fully described hereinafter.

Any suitable number of arcuate horizontal or cross guard wires 30 may be secured in any desired manner, as by welding or the like, at spaced intervals upon vertical guard wires 25.

band 18 is provided with outwardly extending lugs or extensions 41. 42 and turned outwardly at 43, to provide a free end or lip 44. -On the opposite endsof collar 22 are outstanding lugs or extensions 45 which are bent outwardly at 46 adjacent to and spaced from the end 47. The lugs 41 are fabricated of resilientor springable material and provided with an aperture 48 intermediate the

bends

42 and 43 for receiving therethrough the free end 43 of lugs 41. For inter-engaging the lugs 41 and45, a screw driver or other elongated implement 50 or hand pressure, may be used to urge the lug 45 against the lug 41, so that the lug 41 will spring over the free end 47 of the lug 45 and so that the lug 45 will be received in aperture 48. It will be apparent that no screws are necessary for assembling this form of the device upon the handle-orholder.

Another modified form of collar connecting means is shown in Figs. 9, l and 11. I vided with looped or curled ends 51 for rotatabliy mounting buckle cam latch plates 52. Each of these buckle plates has a wide aperture 53, and bar portion 54 by' Which the buckle latch plate is hinged upon the looped end 51. The outer end 55 of each plate 52 forms a hand tab by which the buckle cam plate is moved. A collar 22" has outwardly-extending lugs or extensions56 which are bent forwardly at 57 and have free ends 58. When the collars 18" and 22" are moved toward each other, and the cam plates 52 are in their outward position as shown in dotted outline in Fig. 10, their apertures 53 will receive the free end '58 of the lugs 56. The cam plates 52 may then be rotated or carnmed over the bends 57 against the frictional resistance thereof and as the lugs 56 are somewhat resilient the cam plates 52 will be frictionally held in their locked positions. This permits easy locking of the device upon the handle with finger tip control and also without the use of screws.

In Figs. 12 and 13, there is shown another modified form of the invention. The reflector half 11:: is formed at its top portion with an extension or tab60-which has its free end 61 looped or coiled to provide a hinge formation. The guard half 12 has a vertically extending wire 25' depressed at its upper end to provide a transverse hinge portion 62 which is rotatably received in the looped end 61 of the extension 60. Thus, the guard half 12a is hingedly connected to the reflector half 11 in such a manner as to restrain the guard half 12a against longitudinal and lateral displacement relative to the reflector half 11a.

Adjacent the lower end of the half 12a and interconnecting the lower extremity of wires 25" is a transverse portion 63. A collar portion or member 22:; is formed intermediate its ends with a catch extension 64 which loosely receives the transverse wire portion 63 and rele'asably connects the collar 22a to the guard half 12a in a hooked locked position under tension. The guard half 12a is pulled down to engage or disengage the portion 6 3frorn the loop extension 64.

On the reflector half 11a are a pair of outstanding slotted extensions 65 at opposite ends of the collar which extensions are provided with vertically-extending slots or apertures 66. The collar 22a is formed with laterally oflset, tangentially-extending lugs 67. The lugs 67 are T-shaped and their cross members 68 are in'sertable through the slots 66. The cross-members 68 are then engaged by pliers 69, shown in dotted outline in Fig. 12, and the lugs twisted to fixedly secure the

collars

18a and 22a together.

From the foregoing the-use and method of application of the device should now be readily understandable. When it is desiredto utilize the same as a guard and reflector' for a lamp bulb 31, the lamp bulb is threaded into the holder 32 that is provided either with .or without a switch 33 and a source of current (not shown). The reflector is placed upon the holder so that the tabs 17' and.17" will engage a shoulder thereof and wire guard These extensions are bent inwardly at Acollar 18'" is prois secured to the reflector and about the holder whereby the tabs upon engaging the shoulder positively lock the reflector and guard against axial displacement therefrom. The relatively loose looped connection of the ends 28 of wires 25 with apertures 16 affords a hinge, whereby the two

halves

11 and 12 may be separated to an extent suflicient to permit the device to be readily slid over the enlarged portion of a lamp bulb. The

separable bands

18 and 22 are then moved downwardly to a position about socket 32, as shown best in Fig. 4, and with the

tabs

17 and 17" providing a sure grip on the handle or holder 32 and suitably secured together by the reinsertion of screws 20 to the desired extent.

In the modification shown in Figs. 6, 7 and 8, it is only necessary to bring the lug 41 over the lug 45 in order to secure together the

collars

18 and 22. The form shown in Figs. 9 and 10 requires the rotation of cam plate 52 to receive the lug 56 and frictionally engage the latter, and the form shown in Figs. 12 and 13 need only be moved toward each other so that the extensions 67 pass through theslots '66 and are then twisted approxirn'atel a quarter or a turn.

It will thus be a parent that the lamp bulb is eiteenvely protected fromaccidental impact or jar from any direetion, on one side by the uarclflz and on the other side by the reflector 11. The device may then be used in conjunction with a hand lamp, the light rays being directed as desired by means of reflector 11 or may be suspended by means of a swivel hook 15' and the direction of the light beam governed in accordance with the positioning of reflector 11. Obviously reflector 11 may be comprised of any desired material, and supplied interiorly with any desired reflecting coating, in accordance with the intensity of reflection desired.

From the foregoing it will now be seen that there is herein provided an improved lamp bulb guard and reflector, which accomplishes the function hitherto accomplished only by separate guards and reflector members, which may be manufactured with a minimum of expense and difliculty, and applied to and removed with minimum eflort.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
