UNITED STATES PATENT OFFICE.
FRANK o. nEcK, or MILWAUKEE, WISCONSIN.
Specification of Letters Patent.
Patented Aug. 2, 1921.
Application filed February '14, 1920. Serial No. 358,728.
To all whom itmay concern:
Be it known that I, FRANK O. DECK, a citizen of'the United States, residing at Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Im rovements in Luminous Attachments for lectric- Switch Controllers, of which the following is a specification.
My invention relates to improvements in luminous attachments for electric switch controllers and has for its primary object to provide a device of this character which when connected with the switch button or key will clearly and readily indicate the location of the switch in a dark room without the assistance of other illuminating means.
A further object of the invention resides in. the provision of an attachment of the above character which is simple and practical in construction, capable of being attached to any electric switch controller without altering the same, and which is inexpensive to manufacture.
A Sun further object of the invention lies in providing an attachment of the above character which is detachably associated with the push-button or key, to permit. re-
' moval thereof when its use is not desired.
swit c h Other objects and advantages of the in vention will be a parent during the course of the following escription.
In the accompanying drawingsformlng a "part of this specification and in which like numerals are employed to designate like parts throughout thesame, V r
Figure 1 is a, side elevation of:v a wall 5 is a side elevation of a. socket. showing a modified formof my in-' ven'tion applied thereto; I
-.Fig. 6 is a plan view of the modified form;
1 Fig. 7 isa side-view of the samepartly in section; I g 4 Flg. 8 is a fra 'mentary side elevation of a socket switch s owing another modification of the invention appliedfthereto;
' illuminating means.
material is covered with a. piece of isinglass or transparent material 8 for the purpose of protecting the radium material and thus prolong its usefulness. -A clamping plate or annular ring 9 surrounds the outer edge of the isinglass 8 vand is provided with a plurality of tabs 10 which are arranged at equal distances around its circumference and project radially therefrom. These tabs are bent beneath the plate 5, as clearly shown in F 1g. 4, thus securely clamping together the parts of the attachment. Thls form of my attachment is adapted for use in connection with wall switches of the push-bub ton type,-as shown-in Fig. 1 and desi ated by the numeral 11. The plate 5 being of the same circumference as that of the pushbutton is placed over the end thereof and the arms 6 are bent downwardly along the side of the push-button, so as to. resiliently grasp theperipheral surface of the'button and thus securely'hold the attachment in place. This attachment will illuminate the push-button in the dark, so that it may be easily located without the use of other modification 'of the invention is shown lai'ly adapted-for. usein connection with socket S itches IQ' 'having-a key 13 for con I I t olling-rthsigmakmg and breaking of the circuit. In? order- .for. the attachment to be 5, 6, andfi, and thisform is .p'articui. 7 7
'capable of'use in connection with switches of this type itis necessary to provide an additional plate jli'which is 'of an elongated shape being enlarged at its center. Formed integral and extending radially from both sides at the ends of this plate are strips 15 which-are bent at substantially rlght angles to the said plate. As stated the plate 14 is of an elongated shape which conforms ,some- 51g. 9 1s a plan view of the modified form, an
what to the shape of ,the face of the key 13 over which it is placed. The strips 15 extend down along the sides of the key and are bent around the lower shoulders holdin the plate firmly in place. A luminous dis 16 constructed in accordance with the preferred form of my invention, is placed upon the plate 14 centrally thereof, having the arms 17 arranged so that they will overlap the longitudinal edges of the plate 14 for securely holding the disk in place. Inasmuch '7 as the disk 16 is of identically the same constantially rectangular-shaped metallic plate 20 with a transversely extending slot 21 at one end and a tongue 22 extending from the opposite end, adapted to be inserted through t c said slot. A portion of the plate 20 is covered with any suitable luminous material 23, which is covered and protected by the strip of isinglass or transparent material 24, said isinglass being held in place by the rectangular shaped frame 25 which surrounds its outer edges. Each side of the frame. 25 is provided with a pair of tabs 26 which project therefrom and are adapted to underla the bottom of the plate 20 to securely hold the frame in ,osition. The
It is to be understood that the preferred forms of my invention have been shown and described herein, and that certain changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.
Having thus fully described my invention, what I claim is In combination with an electric switch of the push button type, a circular plate having a luminous face, transparent material covering the plate, a clamping ring having a series of tabs bent to engage the underside of the plate, and a plurality of resilient arms extending at right angles from the plate forming means for attaching-it to the end of the push button.
In testimony whereof, I have afiixed my signature in the presence of two witnesses.
