ILLUMINATOR FOR WRITING ELEMENTS.
Specification of Letters Patent.
Patented Mar. 25, 1919.
Application filed I My 18, 1916. Serial No. 109,930.
To all whom it may concern:
Be it known that I, BYRON L. S. PERRIN, a subject of the King of Great Britain, residing at Ottawa, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Illuminators for Writing Elements, of which the following is a specification.
This invention relates to illuminators for fountain pens, etc., an object of which is to facilitate writing in the dark with writing elements of various types.
Another object of the invention is to provide an incandescent lamp and a source of energy in a writing element of the fountain pen type whereby the lamp may be illuminated by replacing the cap upon the rear end of the element, the lamp being extinguished when the cap is removed from said rear end.
Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and 'pointed out in the claims forming a part of this specification.
Referring to the drawings Figure 1 is a longitudinal sectional view of anilluminator constructed in accordance with my invention, and shown in an operative position, dotted lines being used to indicate an inoperative position of the illuminator closure.
Fig. 2, is an end view of the device.
In the drawings, a housing or casing 1 is provided, which in this instance is shown to be of a cylindrical configuration and is made of any suitable insulated material. One end of said housing is open to permit the insertion of a writing agent 2 thcreinto, the writing agent in this instance being a fountain pen, although it is to be understood that a pencil or the like may be advantageously used, if desired. The opposite end of the housing, as indicated at 3. is closed.
A source of energy is mounted in the housing 1 which in this instance comprises a pair of dry cells 4, arranged in longitudinal alinement and being electrically connected in series in the usual manner. An angle iron 5 is detachably mounted on the inner periphery of said housing adjacent the open end of the latter, and slightly in advance of the batteries 4, the free margin thereof engaging the fountain pen 2. A screw-threaded socket 6 is carried by said angle iron and has mounted therein an incandescent lamp 7. As shown to advantage in Fig. 1, one end of a circuit wire 8 is connected in the socket 6 to one terminal of the lamp, while the opposite end is connected to aninsulated contact 11 which is mounted in the outer periphery of the housing 1 adjacent the closed end 3- thereof. A wire 9 has one end thereof connected in said socket 6 to the other terminal of the lamp and the opposite end connected to the inner electrode of the foremost cell of the batteries 4. A wire 10 has one end thereof connected to a plate 12 carried on the inner face of the closed end 3 and contacted with the outer electrode of the rear cell, while the opposite end thereof is connected to a contact 13 which is mounted in the outer periphery of the housing 1, diametrically to the contact 11.
A closure 15 is provided for the housing 1, which is associated with the latter in the same manner as the cap of a fountain pen is engaged with its barrel, said closure being provided therein with an annular metallic band 16. Therefore when said closure is slidinto engagement with the closed end of the housing 1, the band 16 will connect the contacts 11 and 13, thereby completing an electrical circuit and causing the incandeScent lamp 7 to' be illuminated. Of course, just as soon as the closure 15 is removed from the closed end of the housing, the circuit is automatically broken.
It will be understood that the above description and accompanying drawings comthe casing, a pair of spaced contacts on the g exterior surface of the casing, a connection between one contact and one terminal of the lamp, a connection between one electrpde of the batterv and the other lamp terminal, a connection between the other electrode of the battery and the other contact, a sl p cap to be embraced about either end of the tubular casing, and a band of conducting material mounted interiorly within the cap to connect the spaced contacts when the cap is applied to the end of the tubular casing bearing the contact whereby to illuminate the lamp.
2. A self contained illuminator for writin elements including a tubular housing, a cy indrical writing element located therein approximately one-half the diameter of the internal diameter of the tubular casing, a pair of alined dry cells, in said tubular casing connected in series, a plate at the inner end of the tubular casing making contact with one of the electrodes of the rearmost cell, an angular bracket located'at the open end of the casing, bearing a socket, a lamp mounted in said socket, said angular bracket engaging the writing element to retain the same in place, a pair of spaced contacts at the rear end of the casing externally thereof, a connection between one contact and one terminal of the lamp, a connection between the other terminal of the lamp and one electrode of the foremost cell, a connectionv between the plate and the other contact, a slip cap to engage either end of the tubular casing, and an annular band of conducting material mounted internally in the cap to connect the contacts to illuminate the lamp when the cap is applied to the rear end of the casing.
In testimony whereof I afiix my signature in presence of two witnesses.
