twee xi mis atc .Q'EQT t w-Y Y;.f er.- t T Y J Application:

'a flashlight cap in which the spring that snaps the cover in both the open. and closed position.

also forms the contact with the battery.

to provide a flashlight cap which is of a simple and economical construction and which is readily assembled.

-, taken in connection with the drawing, l-wh ereinz- With these ends in view the invention em bodies a base plate, a cover, and a spring for holdingthe cover in the base plate. a

Other features and advantages of the invention will appear from the followingdescription Figure l is a view showing an elevation of the flashlight with the cover in the open position.

Figure 2 is a cross section through the upper end of the flashlight also showingthe cover in the openjposition Figure 3 is a plan view showing the base plate with the flashlight casing omitted and the cover broken away.

Figure 4 is a view similar to that shown in Figure 2 with the cover in the closed position; Figure 5 is a detail showing the base plate. Figure 6 is a detail showing the cover. Figure 7 is a detail showing the spring.

In the drawing the device is shown as'it would of the cover through the slot 7 and under lugs 21 which may be provided at theends of the slot,

- and then one end of the spring is placed in the be made wherein numeral I indicates the base 'plate, numeral 2 the cover, and numeral 3 the spring.

The base plate 1 may be made of any suitable material or of anydesired size, or arranged in any suitable manner. In the design shown it is" .made with a lamp opening 4 adjacent one end and a threaded sleeve 5 extending downward from the under side thereof in which a lamp as indicated by the numeral 6 may be held. At the opposite end of the baseis a slot '7 anda rectangular shaped opening 8 with'a raised webv 9 between them, and in the side of the base is spacer to locate the base plate a predetermined await-1.9.3.1"; Jls rl aiNd-p51 x cl im;fftol. 240 10165 r And a still further object of theinventio'n is of the base changed to accommodate the casing I ready to be assembled or installed in the flash- ,I claim as new and desire to secure by Letters distance-from the end of 'the battery in the Catsing: J .1 I The cover 2 as shown inFig'ure 6 formed-in asomewhat semi-circular shape with a small projection 12 at the forward end by which it may the'web 9 as shown in Figures 2 and 4. This extension is formed with an indented rib 14 to add strength thereto and the lower end is provided 55:-

with a notch 15 in which an extension '16 at one end of the spring is held and it will be noted that a similar extension 17 at the opposite end of the tion 18 extending downward from one side which will engage the side of a cell 19when the cover 2 is open as shown in Figure 2 to complete a circuit from'the cell 19 through the spring-3, the

It will be understood that the opposite ends of the two cells are connected. Itwill be understood that changes may be made spirit of theinvention' One of which changes maybe in the use of the cap with any other type of flashlight and with the design or arrangement thereof. Another change maybe in the design or arrangement/of the spring or of the contact point extendi'ng'therefrom, and still another may be inthe arrangement of the cover extension in in the construction without departing from the 80.

relation to, the springand base as this may be changed for different designs. I

.The construction will bereadily understood.

from the foregoing description. In use the cap may be assembled by inserting the extension 13 notch 15 at the end of the extension 13 and the other snapped in the opening 8 as shown in Figure 2. The entire cap is then assembled and light casing. r

It will be notedthat this entire cap is formed with three parts as shown in Figures 5,6, and 7, and each of these parts is very simple, whereas all similar caps require many parts and theparts are very complicated in'construction and also in assembling. V v

Having thus fully described the invention what Patent, is: I

p 1. In a flashlight cap of the type having a ings therein, a cover with an extension atone; end thereof extending through an opening in said base and slidable insaid opening, and a U shaped spring having one side bearing against-the edge of an opening in the base and the other against said extension of the cover, said cover extension and spring being shaped and. arranged'so that the spring snaps and holds the coveraopen :and

also snaps and holds the cover closed 7 3. lnagfiashlightecap, aibase withopenings therein, a cover having an extension at one end,

a spring with a contact point extending therefrom, means for holding a lamp in said base, a downwardly extending spacing member at one end of the base for locating the same, means for fulcruming said cover in said base with the extension engaging one end of the spring the other end of which is positioned in the base, said spring arranged to hold said extension below said fulcrum with the cover closed and above said fulmm ,withlthle cover op n, and a m mb on a base for limiting the upward movement of said cover. r

In a flashlight cap of the type where the cover snaps to both the open and closed positions,

a base, a battery, a lamp held in the said base with one terminal thereof engaging one terminal of the battery, a cover fulcrumed in said base, a spring positioned to snap said coverin both the open and olosed" positions, and a projection on ,saidspring adapted to engage the opposite terminal of said battery when the cover is open to complete 1a,oirouit-thronghjsaid basegand lamp. 1 OTTO C.
