Specification of Letters Patent.

Patented May 2, 19316.

. Application filed August 5, 1915. Serial No. 43,836.

T 0 all whom it may concern v .Be it known that JOHN J. DEYIXE, a c tizen of the t nted States. residing at )liddletown. in the county of Middlesex and upon one end of the barrel, to cause the rays of light from an incandescent lamp contained within the barrel to be directed upon a surface with which the point of the pen is engagech. and illuminate an area eiicircling the point of the pen.

A further object of the invention is to provice the barrel of the pen with means for supporting a pen pointin advance of the barrel in such a manner as to provide a passage wav between the supporting' means and the side wallsrof the barrel. through which the ravs of light from the incandescentlamp within the barrel may pass, when the lamp. is illuminated.

A still further object of the invention is to provide a novel means for attaching the cap which contains the switch for establishing electrical communication between the with the end. ot' the barrel distant from that in which the pen point supporting means is disposed.

A still further object of the invention is to provide a holder for the incandescent lamp which permits batteries of various length to be used in connection with the lamp.

. \Vith these andother objects in view the invention resides 1111 the novel combination and arrangement of parts which will be hereinafter more fully described and particularlv pointed out in the claims. I

The preferred embodiment of the invention has been, illustrated in the accompanying drawing, but no restriction is necessarily sis made to the precise details of construction therein shown, as changes, alterations and modifications within the scope ot the claims n'ay be resorted to when desired.

In the drawingze Figure 1 is a side elevation of the pen constructed in accordance with the invention, partlv in section. I 2 is a longitudinal sectional view of the barrel of the pen. showing the pen supporting means and the illuminating device in elevation. Fig. 3 is a viewsimilar to Fig. '2

showing the pen supporting means, the ink reservoir and cap containing the switch for establishing communication between the lamp and batteries, being shown in SGCllt-Hl. Fig. l is a transverse vertical sectional view on the line l-l of Fig. 2. Fig, 5 a-trans verse vertical sectional view on the line 5--.5 of Fig. 2. Fig. (i is a View looking at the inside of the cap contain ng the switch. Fig. 7 is a v ew showing the mechanism. reverse side of the cap. 7

Like characters of reference denote corresponding parts throughout the several views in the drawing. v The pen, which in this instance is a fountain pen, comprises a barrel La closure member a pen point supporting means 3 and an illuminating device l.

The barrel 1 of the pen is prov ded for a 'portion of its length with an enlargement 5,

said enlargement cooperating with the barrel to provide a longitudinally extend.- ingij ink reservoir 6 which is substantially semi-circular incross section, and is dis posed adjacent the end of the barrel containing the pen point supporting means in.

The remainingend ot' the barrel is provided at diametrically opposite po nts w th a recess '4 and a CllClltlll'Gl'tBlltlzlllf arranged slot 8 the purpose of which will be hereinafter described. a

The 6105111 ca) has a reduced )ortion v a H, i adjacent the opened end thereof, which is adapted to be inserted within the open end of the barrel containing" the pen point supporting means when the closing cap, is applied thereto, the closure member and barrel being formed preferably of somesuitable insulating material siich as hard rubber or the like.

The pen point supporting means coinprisesa tubular member 9,.one end of which rece ves the usual-pen point and maintains the same in advance of the open end ot "the,

barrel 1, while the remaining end of the tubular member is connected with the an; reservoir 6 by a. duct 10. T he member 9 is divided into two sections which are removably secured together aslindicated by the numerals l1 and 12. The section 11 receivmg the pen point is channeled in the usual manner in order that ink from the section 12 which serves as an auxiliary reservoir for the ink may communicate with the pen point. In order to maintain the tubular member 9 in spaced relation with the side Walls of the barrel 1 adjacent the opened end thereof the section 12 of tubular member isprovided with radially extending arms 13, which are connected with the side walls of the barrel 1.

Projecting laterally within the bore of the barrel 1 at opposite sides thereof are pins 14 which serve to limit the forward movement within the barrel 1 of a metallic spring 17 is interposed lamp socket 15 in which is disposed an incandescent lamp 16. A coiled expansion between the lamp socket 15 and the pins 11 in the side walls of the barrel 1, said spring normally tending to maintain the lamp socket in spaced relation in the barrel with the pins 14.

It will be noted by reference to Figs. 2 and 3 in the drawing that the enlargement on the barrel 1 causes the rays of light to converge toward the point of the pen when said lamp is illuminated. A battery 18 is positioned within the bore of the barrel 1 and is provided with a contact plate which is normally in engagement with a contact member on'one'end of the lamp 16, said battery furnishing electricity to illuminate the lamp l6.

The end of the barrel 1 distant from that containing the pen point supporting means is closed by a cap 19 which is provided adjacent the periphery edge thereof with a laterally extending annular flange 20, said flange being provlded with a cross bar 21 adapted to contact with one end of the battery 18 when the flange 20 is inserted in the end of the barrel. Spaced from the cross bar 21 is a cross bar 22 which divides the cap 19 into two compartments designated by the numerals 23 and '24. Pivotally connected between its ends to ears on the cross bar 22 is a contact member 25, one end of which is provided with an aperture in which is mounted to turn one end of a threaded shank 26, said shank being mounted for rotation in the end wall of the cap 19. The end of the shank 26 which projects beyond the end of the cap 19 is provided with a resilient arm 27, one end of which has secured thereto a knob 28', the arm 27 and knob 28 serving as a handle by 'means of which the shank 26 may be turned to cause the end of the contact member 25 distant from the end The barrel 1 has extending longitudinally thereof a suitable conductor 29, one end of which is arranged to contact withthe lamp socket 15 while the remaining end of the conductor disposed near the end of the barrel closed by the cap 19' in such a manner that when the shank 26 is turned in a direction to cause one end of the contact member to contact with the battery, the other end of the contact member 25 will engage with an end on the conductor 29 and thereby complete an electrical circuit through the battery and lamp. It is, of course, understood that when theshank 26 is rotated in the reverse direction, the circuit is broken and the lamp extinguished.

A latch member 30 is carried by the cap 19 and includes a U-shaped resilient portion 31 one end of which, bears against the cross bar 22 and has connected therewith a rod 32 slidably mounted in an opening in the cross bar 22 and having an end extending through an opening in the flange 20 and beyond the same to be received in the recess 7 in the barrel 1. The other end of the U- shaped portion 31 bears against the flange 20 and has connected therewith a pin 33 passing through an opening in the flange 20 to be received in the recess 8 in the barrel 1, said U-shaped portion 31 normally serving to hold an end on the pin 33 and an end on the rod 32 extending beyond the flange 20.

'hen it is desired to remove the cap 19 from the end of the barrel to obtain access thereto, the extending end of the pin 33 which is received in the recess 8 in the barrel may be forced within the opening in the flange 20 through which it extends by means of the thumb nail and the cap moved to a position which will remove the projecting end of'the rod 32 from within the recess 7 in the end of the barrel.

In practice when it is desired to illuminate a surface upon which'it is intended to write with the pen, the shank 26 is turned by means of the arm 27 to cause the contact member 25 to establish electrical connection between the battery and lamp, to energize the lamp, so that the rays of the lamp will be directed by means of the side walls of the casing through the passage way formed between the pen point supporting means and the side walls of the barrel. f

hen it is desired to extinguish the lamp, the arm 27 is rotated in the reverse direction and electrical connection between the battery and the lamp discontinued, thereby extinguishing the lamp.

From the foregoing statements it is apparent that the spring 17 maintains the socket 15 yieldably engaged with the pin 14 in the barrel and that the spring further serves to permit batteries which vary in size and length to be used in the barrel of the pen.

From the above description taken in con- 1 '1ecti0n with the accompanying drawing it is readily seen that a pen of the class described has been provided whlch 1s inexpensive to manufactriregimple in construction and highly efiicient in use.

Having thus described the invention, what is claimed as new is 1. A pen of the class described having a longitudinally extending bore enlarged for a portion of its length near one end, said pen being chambered beneath said bore to minating the lamp, said bore being enlarged for a portion of its length in advance of the lamp holder, a pen point supporting member mounted within the bore in spaced relation with the inner peripheral wall thereof, pins extending from said wall in the rear of the pen point supporting member, and a coil spring interposed between the lamp holder and pins.

.3. A pen of the class described having a longitudinally extending bore throughout its length, a source of electrical energy disposed within the bore, a lamp in contact with said source of electrical energy, a holder receiving said lamp and slidable in said bore, a cap closing one end of the bore, a contact member pivotally mounted between its ends on the cap, a stem adjustably mounted in the cap and swivelly connected with the contact member to impart swinging movement thereto, and a conductor contacting with the lamp holder and having a portion thereof arranged in the path of move? ment of the contact member.

4:. A pen of the class described having a hollow tubular body provided at diametrically opposite points near one end in its peripheral wall with a recess and a slot, a cap having an annular flange adapted to be received within said body and to cover said slot and recess, a U-shaped resilient member carried by the cap, a rod connected with said member and having an end extending through said flange to be received in said recess, and a pin carried by said member and having an end extending through said flange to be received in said slot.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN J. DEVINE.
