LATCH FOR SERVICE BOXES o i l Filed July 18 925 Patented Nov. 11, 1930 UNITED STATES PATENT I OFFICE JOSEPH c. LEwIs, or MINERVA, OHIO, ASSIGNOR 'ro CHARLES w. KEPLINGER, E
CANTON, OHIO, RECEIVER OF THE AMERICAN ELECTRIC SWITCH CORPORATION, OF
. MINERVA, OHIO, A GORIEORATION or DELAWARE LATCH roe SERVICE BOXES Original application filed July 18, 1925, Serial No. 44,609. Divided and this Serial No. 188,170.
This invention relates to improvements in entrance or service box construction such as is used at the entrance of an electric line into a building; and the object of the improvement is to provide a latch forsealing Figure 1 is a'perspective view of the im-,
proved box, and I Fig. 2, a section through the box, showing the pivoted latch bar in folded position for shipping. I
Similar numerals refer to similar parts throughout the drawing.
The box 1 may be formed of sheet metal,
of a size to accommodate the switch and fuses, which may be of any usual and well known construction.
The hinged door 2 is arranged to be normally closed upon the box and may be pro vided with an opening 3 to permitthe switch handle 4 to protrude therethrough in the event a switch of the general type shown in my co-pending application Serial No.44,609, of whichthis is a division, is used.
As described and illustrated in that application, the handle 4 may be. folded within the box for the purpose of shipping in order that the boxes may be stacked together in a minimum space without any protruding parts. l
The fiat strip latch bar 5 is pivoted, at its lower end, as on the pivot pin 6, extending into the box from the adjacent side wall 7 of the box, the axis of the pivot pin 6-being perpendicular to the side wall 7, the apertured upper end 8 of the latch bar 5 being adapted to extend through a slot 9 inthe door or cover 2 when the box is in locked position.
This position of the latch bar is illustrated in Fig. 1 and'also in broken lines in Fig. 2.
With the latch'bar in this position the door may be sealed against opening by locating the usual seal through the apertured end of .wall to application filed May 2, 1927.
the latch bar, making it; necessary to break 1 this seal in order to obtain access to the in-" terior of the box.
When it is desired to pack the boxfor shipping, this latch bar is swung downward upon its pivot, into the position shown in Fig. 2 of the drawing, permitting the door 2 to be closed tightly uponthe box, enclosing the latch barentir'ely within the box.
This permits the boxes to be stacked together for shipping and since, as above mentioned, the switch handle 4, may be folded within the box, there are no protruding parts to interfere with the close stacking of the boxes. t
From the above it will be obvious that a simple and eifective latch mechanism is provided by means of'which thebox may-be easily and readily sealed to prevent opening j V .70 Y to the folded position within the box to perg '7 of the door, and which may be quickly-moved mitshipm'ent of the same. I claim A fastener fora container closure member,
comprising a flat strip latch bar adapted to be pivoted at one end to aside wall of the container and extending within the container parallel to the side wall, the other end of the latch bar being adapted to extend through a slot in a closure member of the container,
' and the latch bar being further adapted to be swung about its pivot parallel. with said side V tainer. y
In testimony that I claim the above, I have hereunto subscribed my name.
