SERVICE-BOX COVER.
SPECIFICATION forming part of Letters Patent No. 748,394, dated December 29, 1903. Application filed April 20, 1903. Serial No. 153 ,496. (No model.)
To aZZ whom it may concern:
Be it known that I, HENRY PHILIPP MAR- TIN, a citizen of the United States, residing lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in stop or service box covers; and its object is to provide automatic locking means for said covers.
Another object of the invention is to provide means whereby a cover cannot be removed except when a specially-constructed key is employed.
The invention'furthe-r consists in the construction of a cover which shall entirely inclose the top of the box and yet be accessible when it is desired to examine the interior thereof.
With these and other objects in view the invention consists in the construction of a cover having means secured thereto whereby the cover when placed upon the box is automatically locked thereon.
The invention further'consists in the construction of a locking member whereby it would be impossible to release the same except by employing a specially-constructed key.
The invention further consistsin the novel construction of the parts, as is hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.
In the drawings, Figure 1 represents a side elevation of the device, showing the cover and box partially in cross-section. Fig. 2 is a plan view of the bottom of the cover. Fig. 3 is a detailed perspective view of the pawl. Fig. 4 is a detailed perspective view of a specially-constructed key which I employ in the operation of my device.
Like numerals of reference designate corresponding parts in all the figures of the accompanying drawings.
In the drawings, 1 designates a service-box casing, and 2 a cover therefor.
3 designates a depending bracket formed integral with the cover 2. The bracket 3 is conical-shaped,-so as to permit key-grooves 13 to terminate near an extension 50f a pawl when the same is mounted on said bracket 3. The pawl 4 is preferably constructed from a single piece of sheet metal and has a bottom extension 5 and bifurcated extensions 6, which are adapted to partially encircle the bracket 3 when said cover 2 is removed from the service-box 1. The service-box 1 is provided with inwardly-extending flanges 7, and an annular rim 8 is formed upon the cover 2, adapted to engage the inner edge of the flange 7 when the cover is placed upon the box 1. Lugs or prongs 9 are formed integral with the cover 2, and they are adapted to engage the flange 7 upon its curved inner surface 10. The pawl4 is provided with a curved surface 19 and is adapted to engage the corresponding surfaces 10 upon the boxwhen the said cover is in a locked position upon the same. Formed integral with the depending bracket 3 is a ridge 11 and flanges 12, said ridge and flanges forming deflectinggrooves 13 upon the said bracket 3. The slotted boss or nut 14 is removably secured to the cover 2. It will be seen that the projection 5 of the pawl 4 protrudes beyond the ridge 11 when the said pawl is in a locked position.
Inthe drawings, Fig. 4 illustrates a specially-constructed key comprising a blank sheetof metal 15, twisted at 16 and having a notched end 17. A cut-out portion 18 is formed upon the key, said portion preventing the insertion of the key into the box to a distance greater than is necessary for the operation of the pawl. The twisting of the end 16 provides a flat surface having a notch 17 thereon at right angles to the blank portion 15. The convex surface of the boss 14 prevents water or any foreign substance from entering the box, but permits of the operating-key being inserted into the same.
It will be seen by examining the drawings that if it were desired to remove the cover from the box the key is inserted in the slot of the boss 14 and pressed forward. The notch Y other end, said projection extending beyond 17 engages the ridge 11 and is guided into contact with the projection 5 of the pawl 4.
It will be apparent from the foregoing description that a key not specially constructed if inserted into the box will be deflected by the ridge 11 and will pass the extension 5 of the pawl 4E.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
