Patented Mar. 14, 19331 UNITED STATES PATENT OFFICE HARRY'T. HIPWELL AND HARRY H. HIPWELL, OF PITTSBURGH, PENNSYLVANIA FLASH-LAMP Application filed March 19, 1930. Serial N 437,074.
' mounted in a casing-together with suitable circuit-controlling means.
One object of our invention is to provide a flash lamp having an improved form of cover or cap for the casing which contains the dry cells.
Another object of our invention is to provide a lamp structure wherein the retaining spring for grounding the electrical circuit Serves also to yieldably maintain the hanger or sus ending ring in retracted position.
Stil another object of our invention is to provide an improved form of suspending device on the cap wherebythe lamp may be conveniently hung upon a hook or other sup- 0 port.
a One of the forms which our invention may take is shown in the accompanying drawing, wherein Figure 1 is a'perspcctive view of a lamp, with the suspending device in upright 5 open position; Fig. 2 is a plan view of the structure showing the suspending device in horizontally-disposed open position; Fig. 3 is a view showing the suspending device in retracted or closed position; Fig. 4: is a sec- 330 tional view of the structure of Fig. 3; Fig. 5
is a fragmentary sectional view of the structure of Fig. 1, and Fig. 6 shows the lamp suspended from a vertical wall in substantially a horizontal position.
The lamp casing 7 and its nose or lens carrying portion 8, together with the cells 9 contained therein, may be of conventional form. A cap 10 is shown as having screwthreaded connection with the casing and contains a spring 11 that is compressed against the outermost cell 9, when the cap is screwed in place, and serves as a ground connection between the cell and the cap, thus constituting a portion of the electrical circuit, in a manner well-known in the art.
The enlarged end portion of the spring 11 fits snugly within the cap so that it will not fall from the cap when the cap is unscrewed. A metal disc 12 is interposed between the bottom wall of the p and the Spring so that the spring will hold such disc in place with a yielding force when theparts are assembled.
The bottom wall of the cap is pressed outwardly to form a pocket 13 which has two holes for the reception of the leg portions of a hanger or suspending member 14, the inner ends of these leg portions being turned outwardly as indicated at 15, so that they will engage with the end wall of the slot as shown in Fig. 2, to prevent complete withdrawal of the hanger from the cap. The hanger may be made of spring wireif desired, to cause the ends of the leg portions to frictionally engage the sides of the pocket. The thickness of the hanger relative to the pocket 13 is such that the disc 12 will have frictional engagement with the hanger, to retain it in the position shown in Fig. 3. On the other hand, this force is not sufiicient to prevent sliding of" 0 the hanger 14 from the position shown in Fig. 3, to that shown in Fig. 2.
When it is desired to suspend the lamp in a generally horizontal position from a support such as anail 16, the user will slide the hanger from its retracted position at Fig.
3 to the position shown in Figs. 2 and 6, for example, so that it can be hung upon a hook or other support. It is possible to turn the hanger from the position shown in Fig; 2, to that shown in Figs. 1 and 5, if it is desired to suspend the lamp in a vertical position, the ends 15 engaging the end wall of the recess 13 to hingedly support the member 14 s for limited turning or swinging movement rearwardly toward .the axis of the casing 7 as shown in Fig. 5.
From the foregoing, it will be seen that we provide a suspending member that is more easily operated than are various hangers or suspending rings of the prior art, because it can be readily engaged by the operator to slideit from the retracted position of Fig.
ccurs d flicult gra psuch slnallri g 00 3 to its open position, whereas in various n5 e claim as our invention 1. The combination with a flash lamp casing and a cap therefor, of a suspending member of generally U shape, a recess in said cap having holes through one wall, the legs of said member extending through said holes, and having the inner ends thereof bent outwardly to engage the adjacent walls of the recess, and a disc-like member positioned. over said recess to support the inner ends of said suspending member against movements in a lateral direction.
2. The combination with a flash lamp casing and a cap therefor, of a suspending member of generally U shape, a recess in said cap having holes through one wall, the legs of said member extending through said holes. and having the inner ends thereof bent outwardly to engage the adjacent walls of the recess, and a disc-like member secured to said cap in position over said recess, the said outwardly bent ends of the said member serving to hingedly support the member in its operative position for limited pivotal movements.
3. The combination with a flash lamp casing, of a cap for the casing. a suspending member extending into the cap adjacent to the bottom wall thereof, and being slidably movable cross-wise thereof to and from operative positions, and means on the inner end of said member for engaging the side of said cap to hingedly support said member in its advanced position for swinging movement, and means on said cap for engaging the said member to limit swinging movement thereof in a rearward direction.
4:. In a flash lamp, a battery casing having a depression formed in one end face thereof to serve as a slideway, and a suspending member extended into said depression through an end wall thereof, for movement cross-wise of said casing to and from operative posit-ions, the inner end of said suspending member being turned outwardly for en gaging the end wall of the depression, to hingedly support said member in its operative position for limited pivotal movement rearwardly toward the axis of said casing, the said member engaging the bottom wall of the cap to limit swinging movement thereof in a rearward direction.
5. The combination with a flash lamp casing. of a cap therefor having a recess formed in the inner side of the bottom wall thereof to serve as a slideway, a suspending member slidably extended into said recess, for movement crosswise of the cap to and from operative positions, a disc-like member positioned to close said recess, and means on the inner end of said suspending member for engaging an end wall of said recess to hingedly support said member in its operative position for limited turning movement rearwardly toward the axis of said casing, the said member engaging the bottom wall of the cap to limit swinging movement thereof in a rear ard direction.
6. In a flash lamp, a battery casing having a depression formed in one end face within the marginal edge thereof, to serve as a slideway, and a suspending member extended into said depression through an end wall thereof, for movement cross-wise of said casing to and from operative positions, the inner end of said suspending member being turned outwardly for engaging the end all of the depression, to hingedly support said member in its operative position for limited pivotal movement rearwardly toward the axis of said casing, the outer end of said suspend ing member being positioned inwardly of the marginal edge of said casing when in retracted position.
7. The con'ibination with a flash lamp casing, of a cap for the casing having a recess formed in the inner side of the bottom wall thereof, said recess having holes through an end wall thereof, and a substantially U-shape suspending member having its le s slidably extending through said holes, the inner ends of said legs being bent outwardly for engaging said end wall of the cap to hingedly support said member in its operative position for turning movement rearwardly toward the axis of said casing, the legs of said member engaging the walls of said holes to limit swinging movement of the suspending memher.
In testimony whereof we, the said HARRY T. HIPWELL and IIARRY H. HIrwnLL have hereunto set our hands.
