Description
Patented May 2, 1933 UNITED STATES EMANUEL H. BAER, OF ASSOCIATED, CALIFORNIA INSPECTION PERISCOPE Application filed October 13, 1930. Serial No. 488,219.
This. invention is for an inspection periscope and has special reference to a dev ce especially adapted to the inspection of 1naccessible places.
The main object of the invention is to provide a device with which the interior of a barrel, tank or similar container may be illuminated andinspected, the device being inserted through an aperture in the side or head of.the container, and the inspection conducted by means of a mirror adjacent the illuminating means.
Another object of the invention is to pro vide a device as outlined which is self contained, a battery casing forming a handle therefor, a hollow tube forming one electrical conductor and coincidently, a stem, and an insulated wire within the tube forming the other conductor to an electric lamp.
29 A further object of the invention is to provide a device as outlined which is adaptable to use as a flash light, using standard flash light battery cells, and which is economically constructed, easily repaired and conveniently manipulated and in which the reflecting device or mirror is a-ngularly ad justable by means adjacent the handle and operable by means of the finger of the operator.
Other objects and advantages of the invention will become apparent as the following description is read on the drawing forming a part of the specification.
The invention consists primarily of a handle forming a casing for a plurality of flash light cells, a tube with interposed insulated wire having one end aflixed to one end of the handle and extending axially therefrom, the opposite end of the tube being arcuately formed and terminating in a lamp housing with a socket for a miniature electric lamp, the tube and insulated wire forming the conductors from battery to lamp. A mirror is pivotally mounted at one end to a bracket fixed to the tube adjacent the bend in the tube and is provided with a bell crank which is pivotally connected to a rod extending alongside the handle and slidable in bearings fixed to the side of the handle, by which the angle of the mirror may be adjusted. A knob is provided at the end of the rod for convenience in manipulation.
The invention is adequately illustrated in the accompanying drawing in which Fig. is a side view of the invention;
Fig. 2 is a front view thereof;
Fig. 3 is a plan View of the mirror cass;
Fig. 4 is a section taken on line 4-4 of Fig. 3;
Fig. 5 is an end View of the mirror casing showing the open end and mirror retaining finger; and
Fig. 6 is a sectional view of a barrel indicating the invention in use for inspecting the interior thereof.
A flashlight cell housing 10 of insulating material is provided with threaded conduc tive caps 11 and 12 and is internally provided with the usual terminals and resilient retaining means for the usual flashlight battery cells, and a switch, the interior construction not forming a part of the invention, being well known in the art and therefore not described or claimed.
The invention consists of a hollow member or tube 13 having an insulated wire 14 extending therethrough and terminating in a bell shaped lamp housing 15, provided with a socket 16 for cooperation with an electric lamp 17 and a lens 18 retained in position by a screw cap 19, removal of which permits access to the lamp 17 for replacement. One terminal of the lamp 17 is electrically connected to one terminal of the battery in handle 10 by means of tube 13 and the other terminal of lamp 17 is electrically connected to the other terminal of the battery in handle 10 by means of the insulated 9 wire 14.
Fixedly attached to tube 13 is a bracket member 20. Pivotally mounted in bracket member 20, as at 21, is a bell crank lever 9 having a mirror casing 3 aflixed to one arm 23, by welding or soldering, the other arm 24 being pivotally connected as at 25 to a rod 26 by which the angularity of a mirror 27 is adjusted.
The mirror casing 3 consists of=a bottom 28, sides 29 one end wall 30, the other end 31 being open, and, an inturned flange 32 extending about the periphery'as indicated in Fig. 3. A spring member 33 is formed from the bottom 28 and end 31 by slitting, as at 34, and forming the end 35 upwardly as indicated, thus providing a mirror retainin finger.
he mirror 27 is preferabl silvered glass type, althoug ished metal ma be used.
By drawing downwardly on spring finger 33, the mirror 27 may be inserted or removed for cleaning or replacement.
The usual switch 39 as applied to flash lights is provided on the casing 10 whereby the lamp 17 may be lighted at will.
In use, as applied to the inspection of the interior of tanks, barrels, etc. the lamp end of the device is inserted through an opening such as the bung hole 40 to whatever depth is desired, the lamp 17 lighted by means of switch 39 and the angularity of mirror 27 changed to permit viewing different portions of the inside of the container, the view being directed downwardly alongside the handle to the mirror as indicated in Fig. 6, which clearly indicates its use.
Having described an operative method of constructing and operating the device, it will be understood that variations in construction and arrangement of parts which are consistent with the appended claims may be resorted to without detracting from the spirit or scope of the invention or sacrificing any of its advantages.
I claim 1. An inspection periscope comprising a mirror, a tubular member, a collar on said tubular member, a mirror frame pivotally secured at one end to said collar and having a lever extending at right angles thereto, a connecting rod pivotally secured to the end of said lever and extending parallel to said tubular member, said mirror frame being adapted to removably receive said mirror and having a resilient clip formed from the bottom for securing said mirror in said frame.
2. In combination with a tubular support, a mirror frame consisting of a back, sides and one end, the other end being open, and provided with an upwardly projecting spring finger formed from the back, an encompassing flange forming the top and being adapted to slidably receive and retain a mirror therein, said spring finger cooperating with the edge of the mirror, said frame having one end pivotally related to said tubular support, and a right angle lever highly polof the usual signature.
