Specification of Letters Patent.

Patented Aug. 5, 1919.

Application led September 18, 1914, Serial No. 862,259. Renewed December 14, 1918. Serial No. 266,841.

To all whom it may concern.'

Be it known that L'MoRDUcH L. KAPLAN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain l new and fuseful Improvements in Flashthickness of the material of the vest at the outer side of said pocket, the flash lightbeing thereby held securely; and I associate with the spring clip or member a switch device or mechanism adapted for manual op-v eration for making or breaking the circuit through the lamp.

One very desirable featurefof my invention resides in the fact that a portion of the switch mechanism is located below the spring clip or member in position to engage the upper edge of the vest pocket when the flash light is in such pocket, the edge of the pocket serving as a vmeans for resisting the movement of the switch to make the circuit while the light is being carried in the pocket. The switch mechanism includes a slide or button to be engaged by the finger or thumb in -making or breaking the circuit, and a portion of this slide or button is-below the spring clip to engage the upper edge of the material of the vest pocket when the flash light is placed therein.

In carrying out my invention I preferably construct .the barrel or exterior'ca'sing of the flash light to resemble in appearance a fountain pen, and upon the exterior of this outer shell or casing I secure a spring clip preferably imitating as far as possible the spring clip on the side of the barrel of a fountain pen, and I associate the circuit closing means with this spring clip.

The invention will be fully understood from the detailed description hereinafter presented. reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation of a flash light embodying my invention;

Fig. 2 is a central vertical section on an enlarged scale through the same;

Fig. 3 is a transverse section through one end of the same on the dotted line 3 3 of Fig. 2;

Fig. 1 is a similar section taken on the dotted line 4--4 of Fig. 1, and

Fig. -5 is a central vertical section through the upper section of a modified construction of the flash light, the modification residing in the formation of the slide utilized for making or breaking the circuit through the lamp.

In the drawings, referring more particularly to Figs. 1, 2, 3 and 4, 10 designates the exterior shell or casingl of the flash light, and this shell or casing is of elongated form and meant to imitate as far as convenient the appearance of a fountain pen. The casing 10 will preferably be of metal and at one end carries a lamp 11 and reflector 12 therefor. The casing 10 is shown as made in two sections 13, 14 connected together at their meeting portions by a bayonet joint. The reflector 12 carrying the lamp 11 is secured within the outer end of the casing 10 by means of a bayonet joint. The detailsv of the two bayonet joints will be understood on reference to the drawings and need not be specifically described since the same are not claimed herein. The casing section 14 is of greater diameter than the casing` section 13, andy the latter is of proper diameter to snugly receive the battery 15, one end of which engages a terminal of the lamp and the other end of which is engaged by a coiled spring 16 which is a conductor and at the same time maintains the engagement of the battery with the lamp .terminal in a customary manner. Within the outer end of the casing section 14 is provided a disk or frame 17 of insulating material, and this Adisk is formed with a recess 18. One end of the rod or wire forming the spring 16 is inserted through the disk 17 and bent laterally within the recess 18, as'shown in a plate 21 which is integral with and has projected therefrom in line with the length of said shell or casing, a clip 22 which is of metal and normally separated, except at its outer end, from the side of the shell or casing 10 and has on its outer end a ball or enlargement 23, this ball or enlargement constituting the outer end of the clip.

Within the casing section 14 is arranged a slide 24 having a laterally bent outer end 25 and bein connected at its other end with the shan 26 of a slide or button 27 by means of which the slide 24 may be moved longitudinally 14 to make or break the circuit through the lamp. The end 25 of the slide 24 extends inwardly to lap uponthe end.. 19 of the spring 16, but said end 25 is normally separated from the end 19 of the spring, as shown in Fig. 2. When it is desired to complete the circuit through the lamp the button or slide 27 is manually moved to cause the bent end 25 of the slide 24 to pass into electrical connection with the end 19 of the spring 16, thus closing the circuit through the lam and causing the latter to light. When it 1s desired to break the circuit, the slide or button 27 is moved toward the outer end of the casing section 14 a suiiicient distance to separate the bent end 25 of the slide 24 from the end 19 of the spring 16. The clip 22 is formed near its shank end with a longitudinal slot 28 through which the shank 26 of the button 27 extends and the ends o f which slot limit the movement of the button 27 and slide 24. The edges of the slot 28 by their engagement with the sides of the shank 26 serve to ide the 'button 27 in its movements to actu ate the slide 24 and also to maintain the shank 26 and button or slide 27 in correct position. The button or slide 27 is shown in Figs. `1 and 2 as spherical in form, but the special formation of the slide or button is unimportant. The shank 26 is concealed behind the clip 22 and its inner end extends through a slot 29 in the casing section 14 to receive the inner end of the slide 24, said slot 29 serving to aid in guiding the shank 26 in its movements. The slide 24 is moved in a direction toward the outer end of the clip 22 when it is desired to complete the circuit and light the lamp and in a direction toward the shank end of said clip when it is desired to break the circuit and extinguish the lamp. The flash light shown is meant to be carried in the upper vest pocket or in some pocket of the clothing of the user .ind it is of considerable importance that the switch or circuit closer be guarded against accidental movement whereby the circuit may be closed, and in accordance with my invention this result is very -desirably` and conveniently obtained by the association of the slide or button 27 with the clip 22.

of the shell or casing section When the fiash light is carried in the upper vest pocket or other pocket of the user, the fabric at the front of the pocket is caused to pass between the clip 22 and casing section 14 and the upper edge of the said fabric presses against the shank 26 of the slide, with the result that the cloth of the garment at the front of the pocket will keep the slide 24 in its inoperative or circuit breaking position and resist any tendency of said slide to move to its circuit closing position. The clip 22 serves to retain the Hash light in the pocket and receive behind it a portion of the switch or circuit closing mechanism in position to engage the upper edge of the pocket when the with the clip embracing the fab-ric at the front of such pocket. In the construction shown in Figs. v1 and 2, the clip 22 also serves as a guide for the exterior portion of the switch mechanism.

- My invention resides more particularly in theassociation of the ,switch or circuit closing mechanism with the clip 22 in such manner that'the clip may coperate/ therewith and also receive behind it a portion of such mechanism in position to engage the upper edge ofthe pocket receivingthe flash light. f

In Fig. 5 I show a modifica-tion. f 30 represents the handle or shank section of the exterior casing, and within the outer end of the casing section 30 is provided a disk 31 of insulating material and spring 3,2,saidV disk 31 having a recess 33 and said spring32 having a laterally bent outer4 end 34 within said recess, the disk 31 and spring 32 corresponding exactly with the disk and spring shown at theouter end of theI casing section 14 in Fig. 2. Upon the exterior ofthe casingsection 30'is providedwa yspring clip 35, the shank end or plate portionl 36 of which is secured to the casing section 30 by means of rivets 37. Within the case section 30 in the plane of the plate or shank portion 36 of the clip is provided a slide 38 of conducting material, this slide having at its outer` end a laterally bent portion 39 overlapping the bent end 34 of the spring 32 and normally separated therefrom. The slide 38 is connected by a rivet 40 with an exterior slide 41 which is partly concealed behind the plate 36 and clip member 35 and has behind said clip member 35 a laterally extending flange 42 to engage thel fabric at the front of a pocket when the flash light is inserted therein. The outer end of the slide 41 is formed with a head 43 for convenience in the manual operation of the' slide by means ofthe thumb or finger. The slide is formed with a longitudinal slot 44\'throu'gh which the rivets 37 pass and which rivets in coperation with said slot serve to guide the slide 41 in its movements to make and break the circuitand also to maintain said slide in correct flash light is placed thereiny position on the casing section 30. The rivet by means of which the slide 41 is connected withl the inner slide or switch 38 passes kthrough a slot in the casing section. 30. y l/Vhen the end 39 of the inner slide or swltch` 38 is separated from the bent end 34 of the s ring 32, there will be no circuit throu h l tli exterior sliding member for manual operae lamp, and when it is desired that t e lamp sliall light, the slide 41 will be moved in a' direction toward the outer endof the clip 35 so as to'carry the bent end 39 of the Ainner slide 38 into engagement with the bent end 34 of the spring 32, thereby completing the circuit. When it is desired vthat the light shall be extinguished, the slide 41 will be moved outwardly or toward its normal position, shown in Fig'. 5, to separate the parts 39, 34 and break the circuit.-

In the construction shown in Fig. 5 I attain the result of -preventing the accidental lighting of the lamp while `being carried in the pocket in the same manner that that result is secured in the construction shown in Fig. 2. The flange 42 on the slide 41 will engage the fabric at the front of the pocket and said fabric will prevent the downward movement of the slide 41 to circuit closing position. In the construction shown in Fig. 1 the spring clip acts as a guide for the shank of the exterior slide, and inFig. 5 the rivets securing the clipserve as a guide for the exterior slide 41, the clip or its parts in each instance coperating with the exterior slide and said clip also receivingbehindit a portion of the switch mechanism adapted to engage the upperledge of the pocket inwhich the flash li lit may becarried for preventing the accidental lighting of the lam in each instance also I avoid the use oi) the spring clip itself as a means for making and breaking the lcircuit and allow the clip to ,perform its customary functions in addition to coperating with the exterior or slide portion of the switch or circuit closing mechanism.

In both forms of Kthe invention illustrated in the'drawings, I have associated the switch novelty and is highly desirable in` vie-W of v its efliciency. l
