5 Claims.
This invention relates to a portable flashlight which, as shown herein, is designed for combination with another article such as the leather key case illustrated in the drawing. This invenwith a pair of radially projecting flanges, 2, which extend in closely parallel planes from the lower side of the cylinder, I, for attachment of a key case, 3. As shown, this case may consist of a folded piece of sheet material such as leather, or
5 tion, however, is concerned primarily with the structure and operation of the elements of the imitation leather, one leaf, 4, being secured to flashlight itself. One object of the invention is the flanges, 2, by suitable rivets, 5, and the other Ato provide a cushioned mounting for the battery leaf, 6, being secured in closed position by means and lamp in the outer shell; another object is to of a two-part snap fastener having one part, l,
provide switching means for connecting the lamp mounted on the flanges, 2, and the other part, 8, 10 to the battery either momentarily or for a longer secured in the leaf, 6. A suitable pivot, 9, is shown period, at will. Another object is to arrange for for securing the keys in position, one such key means for mounting the lamp in a denite posibeing indicated in dotted ouline at II! in Fig-- tion whenever it is removed and replaced so as ure l.
to insure satisfactory operation of the parts. The A cylindrical battery, II, is carried slidably in 15 invention consists in certain features and elethe cylindrical shell, I, as seen in Figure 2. One ments of construction in combination, as herein end of said shell has an inturned flange, I2, which shown and described and as indicated by the connes a flanged push-button, I3, whose central Claims, Y portion is protruded through the end opening in In the drawing; k the shell bounded by said flange, I2. A spirally 20 Figure 1 is a side elevation showing a flashlight coiled spring, I4, is pocketed at one end in the combined with a keycase in accordance with this push-button, I3, and at the other end bears invention, against the end of thevbattery, II At the oppo- Figure 2 is a longitudinal section taken axially site end the battery is provided with a center conwith respect to the cylindrical shell of the flashtact element, I5, adapted to engage the center 25 light, contact, I6, of the incandescent lamp bulb, I1.

Figure 10 is a detail perspective View showin The lamp is held in position against the reacthe lamp-supporting collar of Figure 8 on a tion of the spring, I9, by a hood or tip, 20, which 45 larger scale. iS preferably of translucent material, such as Figure 11 is adetail section taken at line II-II Catalin, Pyralin, Celluloid or glass. The inner on Figure 10, end of the tip, 20, is externally threaded, and
Figure 12 is a fragmentary detail showing a engages a pressed thread, v2l, in the end portion modied structure of the hood or tip for securing of the shell, I. The outer end of the tip may be of 50 a decorative effectany desired contour to provide an ornamental As shown in Figures l and 2, the flashlight appearance, and is centrally apertured at 22 embodying this invention includes a cylindrical for emission of the direct rays from the lamp, shell 0r Casing, I, which may be made of sheet IT. The lamp is shown as of the type having a metal bent into cylindrical form and provided reduced end portion, with the glass Wall thck- 55 ened at the extreme end forming a lens at 23 serving to concentrate the light emitted through the opening, 22, in the tip or hood, 24. The aperture, 22is smaller than the diameter of the end portion o1' the lamp so that the inner surface of the hood, 20, surrounding the aperture, 22, forms a stop shoulder against which the lamp is pressed by the spring, I9.
The spring, I4, is preferably somewhat stiil'er than the spring, I9, so that inward pressure upon the push-button, I3, is transmitted through the spring, I4, to the battery, Il, and shifts the latter axially to carry its center contact, I5, into engagement with the contact, I6, of the lamp and close the circuit. Instantly upon release of the pressure at I3 the battery will bereturned to its original position by expansion of the spring, I8, and the circuit will be opened. Thus, when the circuit is closed by means of the button, I3, the finger pressure upon the button must be exerted continuously as long as the light is wanted. But, when desired, the tip or hood, 20, may be screwed farther into the shell, I, compressing the spring, I9, so as to bring the lamp contact, I6, into engagement with the battery contact, I5. With the construction shown in Figure 2 the pressure for making this contact is transmitted from the hood or tip, 20, through the reduced end portion of the lamp adjacent the opening, 22, and thence through the lamp body and its base, I8, to the spring, I9. If the tip, 20, should be screwed in farther than necessary-that is, after contact is established between the elements, I5 and IB- the excessive movementv will be absorbed by the slight compression ofthe spring, I4, at the opposite end of the battery, II; thus, there is no serious danger of crushing the lamp, I1, under such circumstances.
However, it is preferable that pressure on the glass portion of the bulb, I1, be avoided at all times. This result is accomplished by the construction shown in Figures 4 and 5, in which the threaded base, I8, of the bulb, I1, is screwed into a collar, 30. The collar has an inturned flange, 3|, against which the inner end of the threaded base, I8, abuts, thus definitely positioning the lamp in the collar. The collar also has an outwardly extending ange, 32, which may be slightly concave toward the battery, Il, to serve as a seat-for a coil spring, 33, whose opposite end engages the end of the battery, II, and the inner surface of the shell, I, in the same manner as the spring, I8, in Figure 2. Thus, when the tip or hood, 20, is screwed inwardly into the threaded end of the shell, I, the inner end surface of the hood, 20, at 24, presses against the an'ge, 32, of the collar, and thus carries the lamp bodily toward the battery for engagement of its center contact, I6, with contact, I5, of the battery. With this arrangement the parts may be Soproportioned that the inner surface of the hood, 20, does not touch the lamp, I1, at any point, but affords clearance which insures that the glass portion of the lamp bulb shall not be subjected to pressure or twisting strains in the adjustment of the parts or in use of the flashlight. The lamp is centered in the shell, I, by means of the ange, 32, of the collar, this ange being fitted approximately to the inner diameter of the shell, I, with only suicient clearance to,
permit it to pass the inwardly pressed thread at 2|. It will be understood that with this arrangement the push-button, I3, and its spring, I4, may be employed in the same manner as in the structure of Figure 2. Y
Figures 8 to 11 show a slight modification of the collar for supporting the lamp within the hood or tip, 20, but out of contact therewith. In this construction the collar, 40, is formed with a threaded annular portion to receive the threaded base, I8, of the lamp, I1. At one end the collar is crimped inwardly, as seen at 4I, to form a stop shoulder dening the limiting position of the lamp base when screwed into the collar, and the material then extends outwardly in a ange, 42, which fits the inner diameter of the shell, I, with suilicient accuracy for centering the lamp, but with clearance which permits removal of the collar and lamp from the end of the shell past its thread, 2|, when desired. A coil spring, 43, might be made to react between the end of the battery, Il, and the flange, 42, of the collar, but, as shown, it is spirally coiled so that its largest turn engages the end of the battery, I I, and the inner surface of the shell, I, while its smallest turn presses against the insulated surface, 44, of the lamp base just inside the crimped stop shoulder, 4I thus the coils are adapted to collapse very closely Without interference when the battery, II, is shifted by means of the pushbutton, I3, or the lamp, I1, is shifted by screwing the tip, 20, into the threaded end of the shell, I. With this construction also, the hood, 20, is formed internally to avoid all contact with the lamp, I1, so that it controls the position of the lamp solely by pressure of its end surface, 24, against the outwardly extending flange, 42, of the collar, 40.
For the ornamental effect I prefer to make the hood, 20, of translucent material, as already mentioned, and, preferably, this material may be made in various colors. Without, in any way, decreasing the eil'ciency of the lamp, I1, and its direct rays emitted through the opening, 22, in the hood, the color of the latter gives a very pleasing appearance to the article, whether the lamp is lighted or not. And for further ornamental effect I may have the lamp made with an annular band of color applied either inside the lens element, 23, as indicated at 26, or applied outside the lamp as a coating of color, or else as an inserted ring of transparent colored material, as seen at 21 in Figure 12, so that the circle of light which is projected through the lens, 23, and the opening, 22, is given a margin of color, adding interest and beauty to the effect.
In all three forms of the device the spring, I4, and the push-button, I3, may be removably secured together by forming two or more dents at I3l1 in th annular wall of the push-button,
these dents being positioned to overhang the large coil of the spring, I4, which is pocketed in the recess of the part I3. This adds to the convenience in the handling of these parts whenever the battery, II, is removed and replaced by a fresh battery, or if any other adjustment of the device becomes necessary.
A somewhat similar expedient may be applied to the spring, 33, and collar, 30, of the structure shown in Figure 4. The edge o f the ange, 32, is formed with short prongs 32a, which are bent back slightly to overhang thel rst coil of the spring, 33, which is seated against the flange, 32, thus connecting the spring positively to the flange. The terminal coil at the opposite end of the spring, 33, is a fairly close fit in the casing, I, so as to frictionally engage the casing, although it may be readily withdrawn when the hood or tip, 20, is removed for replacement of the battery. On such ocasions the permanent assembly of the 240. LLiJmnJf-ll fori,
spring, 33, and the collar, 30, facilitates handling of the parts, and prevents the collar and lamp, I1, from being snapped out of the casing by the force of the spring, 33, when the tip, 20, is unscrewed.
While there is shown and described herein certain specic structure embodying the invention, it will be manifest to those skilled in the art that various modifications and re-arrangements of the parts may be made without departing from the spirit and scope of the invention, and that the same is not limited to the particular form herein shown and described, except in so far as indicated by the appended claims.
