LAM]? HOLDER.

all whom it may mam.-

Beiti known that I, HERMAN Bmonn, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Lamp Holders, of which the following is specification, the principle I of the inventionbeing herein explained and thegbestmodelinjwhich I have contemplated applying that principle, so as to distinguish 1 it from other inventions.

,Qt/Iydnvention relates to lamp holders and particularlyqto a; device of this character utilized 1 for holding electric lamp bulbs. Particularl my invention relates to a de' yic e oftthis 1 character which enables the user to, support the lampanywher-e and at anyfarigle. Furthermore, the device is one which. is economically manufactured, of neat appearance, and one which requires no tools "I to apply and whoselusefulness it is difficult to impair.

y Thefannexedfdrawings and the following lescriptionset forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

,In said annexed drawings:

Figure 1 is an elevation in which my improved holder is supporting a lamp substantially in vertical position by means of beingclamped to abeam; Figure 2 is an elevation in which my improved holder is supportlng a lamp at substantially an angle of forty-five degrees a portion of the cord and jaws being indicated bydottce lines when the lamp is held at this angle by means of the-holder being clamped to the lamp cord itself; Figure 3 represents a plan view, taken in the plane indicated by the ,line III-III, Figure 5, the lamp being removed Figure 4 represents a bottom plan, taken in the plane indicated by the line IV-IV, Figure 5, the lamp and socket being (removed; Figure 5 represents a vertical section, taken in the plane indicated by the line V V, Figure 4, Figure 6 represents 1 a plan view, taken in the plane indicated by the. line li -IV, Figure 5,'tlie lamp, socket and jaw-actuating finger-pieces being removed; Figure 7,.is adetail of one of the UV-shap.ed finger-pieces; and Figure 8 is an end elevation of .one of the clamping jaws.

" Referring to-the annex drawings, my improved lamp holder is designed to support Application-filed August 20, 1919, Serial No. 318,736. Renewed December 24, 1921; Serial No. 524,744.

a lamp 1 seated ina socket 2 and provided with a cord 3 adapted at its free end (not shown) to be attached to any suitable light circuit. My improved holder is designed to be clamped to or supported by any suitable accessible extraneous supporting means, such as a beam 4, or supported by being clamped to any desired section 5 of the lamp cord 3 itself, Figure 52. The clamping means are a pair of jaws 6 secured in suitable sockets 7 of a two-part body member 7. The actuating members are a pair of U- shaped finger-pieces 8 dctachably connected to the respective parts of the body member 7 by means of sockets 7 Means are provided tending to hold the jaws 6 closed and being mounted in the ears 7 of the body member 7. Upon one part of the body meniber 7 I have provided aseat 10 for the socket 2 of the lamp 1, said seat being provided in its outer wall with an open slot 10' of such a size and construction as conveniently to allow the lamp cord 3 to pass therealong to enable the proper seating of the socket 2, as plainly shown in Figure 2. One pair of sockets 7 are disposed adj acently the baseof said socket seat 10' so that one of the jaw-actuating U-shaped finger-pieces R is disposed in that position relatively to the lamp l and the socket 2. plainly shown in Figures 1 and 2. The lamp cord is adapted to pass through the other fingerpiece 8, as also plainly shown in said Fig ures 1 and 2.

The socket seat 10 is of spring material and is provided with the peripheral shoulder 10", of the construction plainly shown in Figure 5, whereby the socket 2 is firmly held in said seat 10. Other slots 10 are formed in the socket seat 10 for accommodating the socket key, so that the lamp can be turned to any desired convenient position for manipulating the key. For turning the lamp to bring the key into the most conturned, and thenthe socket snapped into the seat, with the key registering in the desired slot 10 It will be noted that the jaws 6 are of such relative sizes as to enable one to just clear v through the latter,as plainly shown infFig.

The fingerpiecesS are formed of spring material so that they grip the sockets 7' very firmly and cannot be unintentionally withdrawn therefrom. Their construction is plainly indicated in Figure 7. 7 By means of the provision of the detachable linger-pieces 8, I am enabled to provide tor the intersection. of the finger-[neces 8 the cord 3 without the necessity of having said finger-pieces so large and unsightly j as to enable the passage of the lamp 1 and the socket 2 therethrough. By the proa -vision of the one finger-piece 8 adjacently to the seat 10, I have designed a holder which is more economical, more eiiectivem its operation and more sightly than would be the case if saidfinger-piece were attached to other supporting parts of the body member 7. It is necessary to use no tools whatever in the application and use of the device.

What I clainr is: r V 1. lamp holder comprising a bod'yunember formed of two sections centrally hinged together, each of said sections having sockets formed at its Opposite ends, means carried by oneof said sections for seating the lamp,

' said finger pieces being disposed adjacently clamping meansiitted in the sockets formed at one end of the body portion, and finger pieces fitted in the sockets formed at the opposite end of said body'portion.

2. A lamp holder comprising a body member formed of two sections centrally hinged together, sockets formed at the opposite ends 'ofieach section, means carried by one section for seating the lamp and provided with a plurality of key-receiving slots and an open slot for the lamp cord, clamping jaws secured within the sockets formed at one end of the body member, and finger pieces secured within the sockets at the opposite end of said body member,

3,111 a lamp holder, the combination with a lamp socket and cord; of a body member provided with a seat "for said socket, clamping jaws sup-ported by said body member and means tending to hold the same closed, 'U -shaped finger-pieces detachably connected to said body member, adapted to open said jaws, and through which said cord is adapted to-pass, one of said socket-seat, and said seat being formed with an open slot adapted to receive said cord.

4. In a lamp holder, the combination of a body member means supported thereby for seating the lamp and provided with a plurality of key-receiving slots and a marginal shoulder, clamping jaws supported by said body member and means tending to hold the same closed; and finger-' pieces supported by said body member adapted to open said jaws.

5. In a lamp holder, the combinationof a 7 two-part body member; means supported thereby for seating the lamp; clamping jaws fixedly secured within sockets formed on said body member, one of said jawsbe ing formed so as to pass through the other; means tending to hold said jaws closed; and linger-pieces d'eta'cha'bly secured within sockets formed on said body member and adapted to open said jaws. U V 1 6. In a lamp holder, the combination of a body member; means supported thereby for seating the lamp clamping jawsfl secured within sockets formed at one end of. said body member, one of said jaws being designed just to clear through'the other, said jaws being formed} with curved outer ends providing a four-point contact; means tending to hold said jaws closed; and fingerpieces detachably secured within sockets formed at the opposite end of said body member and adapted to open said jaws.

7. A lamp holder of the character described, comprising a pair of pivotally' con nected body members, forming a pair of forwardly projecting clamping jaws and rearwardly projecting actuating arms; 'a spring for normally holding said jaws in clamping position; alamp' supporting member mounted on one of said actuating. arms and additional clamping members secured tothe ends of said jaws, one of said additional clamping members being formed topass through the other. i

8. A lamp hlder of the character described comprising a pair of pivotally connected members, each having an intermediate portion and end portions disposed at, an angle with respect to the intermediate portion and extending in opposite directionsthere'from, said members being pivoted each to the otherat the bend between the intermediate portion and an end portion, the end portions ofthe two members adjacent the pivot being adapted to' serve as actuating arms and; the opposite end portions of the members being: formed to permit movement s of one past theother and adapted to serve as clamping jaws, a spring for normally forcing the jaws toward clamping position, and a lamp holder carried by one of said members. I

9. A lamp holder of the character described comprising a pair otp-ivotallyconnected members, each having an intermediate portion and end portions disposed at an angle with respect to the intermediate portion and extending in opposite directions therefrom, said members being pivoted each to the other at the bend between the intermediate portion and an end portion, the end portions of the :two members adjacent the pivot being adapted to serve as actuating arms and the opposite end portions of the members being formed to permit one to pass through the other and ada )ted to serve 10 as clamping jaws, a spring or normally forcing the jaws toward clamping position, and a lamp holder carried by one of the end portions serving as an actuating arm.
