Application May 1, 1937, Serial No. 140,259 1 Claim. (01.240-1015) This invention appertains to new and useful improvements in flashlights and more particularly to a flashlight adapted to be carried by a person.

The principal object'of the present invention is to provide a flashlight which can be strapped to the body of the user so that the user will have both hands free.

Another important object of the invention is to provide a flashlight constructed in such a manner that it can be carried conveniently on a person's body and be available for use at all times. I

These and. various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a top plan view of the device.

Figure 2 is a horizontal sectional view through the device.

Figure 3 is a rear elevational view.

Figure 4 is a vertical sectional view on the line 4-4 of Figure 2.

Figure 5 is an enlarged fragmentary detailed sectional view through the switch.

Figure 6 is an enlarged side elevational view of one of the shells of the device with certain parts broken away.

Figure 7 is a fragmentary front elevational view of the device.

Figure 8 is an end elevational view showing the inner end of one of the shells.

Figure 9 isa fragmentary plan view of the blank from which the shell is constructed.

Figure 10 is a diagrammatic view disclosing the electrical connection between the electrical devices involved.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1 that numerals 5--8 represent cylindricalshaped shells angularly disposed with respect to each other as converging toward the rearwardly tapering case I which houses the reflector 8 and which has at its front side the removable rim 9 for holding the lens iii in place.

The reflector 8 carries the socket structure il in which the bulb i2 is disposed.

As is suggested in Figure 9, each of these shells 5--6 is constructed of a sheet of sheet metal having its inner end slit at the points i3 to define lugs l4, and further formed to provide outstanding lugs i5 for attachment to the case I.

Mounted upon the case I is the small switch box IE having the slot I1 in the top thereof through which the handle portion I8 01 the contactor operating arm. I! extends, this arm being on the fulcrum 20 and having its lower tapered end operative against the spring contactor 2|.

A binding post 22 secures one end of the con- 6 tactor 2| to the insulation plate 23 while the opposite end of the contactor 2| is operative against the contact forming binding post 24. A spring contact finger 25 extends from the post 24 and bears against the center contact of the 10 bulb l2. It will be observed in Figure 4 that the socket H is in the form of an arm which has direct contact with the metal of the case I. I

' An arcuate-shaped member 23 has portions adjacent its ends secured to the shells 5-6 and 15 this arcuate member 26 is provided with slots 21 at its ends for receiving a strap member whereby the device can be strapped to the user.

The shell 6 is provided with the hinged closure 28 carrying the spring contact 28 bearing against 20 the side of the battery cell 30.

The shell 5 is provided with an elongated passageway 3| containing a strip of insulation 32 through which the conductor 3| is longitudinally disposed, one end being connected to the hinge 26 35 of the closure 36 of the shell 5 and its opposite ends having the connection 31 to the contact lid engaging the carbon terminal of battery cell 30.

The outer end of the shell 5 is provided with 30 the aforementioned closure 36 having an insert 36a of insulation to which aspring 38 is secured by=securing elements 38a, which also serve to secure the closure 36 to the-hinge 35, and these securing elements act as an electrical connection 35 between the battery engaging spring 38 and the hinge 35 and conductor 34.

As can be seen in Figures 6 and 8, the inner end of each of the shells 5-8 has its lug por-. tion, I bent against the inner and outer sides 40 of the closure disks 40 in alternate disposition and a contact extending through each of these disks 40 and denoted by the numeral 4| engages the carbon post of the corresponding battery cell 33 or 30.

.The circuit connections, as shown diagrammaticaly in Fig. 10, are as follows: carbon post of battery cell 30 to contact a, which is connected by a suitable lead 31 to the conductor strip 34, hinge 35, elements 38a, spring 38, cell 39 50 which is insulated from the casing by the usual cardboard wrapper, carbon post of cell 39 to contact 4|, and by a suitable connector from the contact I to the binding post 22 ofthe switch element 23, lamp l2 and socket i I to the u casing 1, 6, which is connected by the spring 29 to the zinc element of the cell 30.

While the foregoing specification sets forth the invention in specific terms, it is to be understood thatnumerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

What is claimed as new is:

A lamp structure comprising an arcuate-shaped n, BURGESS. 1o
