Specification of Letters Patent.
Patented Sept. 16, 1913.
application filed March 15,1912. Serial no. 684,052.
To all whom it may com of Texas, have invented certain new and useful Improvements in SewenClean-Out Covers, of which the following is a specification.
My invention relates to new and useful improvements in sewer clean out covers,
and its object is to provide a cover for the.
clean out pipes of sewers, which cover will be securely held in place under ordinary circumstances and cannot be removed except by "authorized "parties carrying "a certain mechanism.
A further object of the invention is to provide a device of the character described that will embody an inexpensive and simple construction and that will be correlated with a fastening means, but may be released without difiiculty by a person provided with the proper key.
With these objects in view, my invention has relation to certain novel features of the construction and operation, an example of which is described in the following specification and illustrated in the accompanying drawing, wherein:
Figure 1 is a plan view of a sewer pipe clean out provided with the herein described cover, the pipe being shown embedded in the earth in the usual manner. Fig. 2 is a transverse, vertical, sectional elevation taken upon the line A-A of Fig. 1. Fig. 3 is an underside view of the cover. Fig. 4: is a transverse, vertical, sectional elevation, showing the outlet endof the clean out cas: ing, the cover being removed therefrom. The section in this case is taken upon the line 13-13 of Fig. 1. Fig. 5 is plan'view showing the outlet of the sewer clean out casing, the cover thereof being removed. Fig. 6 is a perspective detail view of the key form of key, adapted to release the fastening by which the lock or fastening means of the cover may be released.
Referrlng now more particularly to the drawings whereln l1ke numerals of reference designate similar parts in all figures, the
numeral 1 denotes a metal casing adapted to be embedded in the ground and to communicate at its lower end with a sewer, the upper end of said casing being provided with an aperture flush with the level of the street or road beneath which the sewer runs. A collar 2 formed integral with the casing 1 collar 2.
encircles the aperture in the top of said casinga The interior surfaceof the collar 2 is provided with a flange 3 forming a seat for the circular cover 4., which may be given any of the many designs in common use.
At one point a break is provided in the seat 3, as indicated at 5," the aperture forming said break being extended slightly into the At a point removed substantially 90 degrees from the opening 5 a channel 6 substantially vertical is provided in the interior surface of the collar 2. Upon the under surface of the cover 4 adjacent to the edge thereof, a pair of apertured lugs 7 are provided between which lugs a hook member 8 is pivoted. The upper edge of the hook member 8 is provided with a transverse slot 9,-which slot is adapted to engage a lip 10 projecting slightly dow ward from theseat 3 adjacent to said hook. When the hook is in a substantially horizontal position, as shown in dotted lines in Fig. 2, lip 10 is disengaged from the slot 9, and the cover may be raised.
In order to prevent any possibility of the cover being removed by first raising a point thereof diametrically opposite to the hook, a curved finger 11 is integrally provided upon the under surface of the cover at the point specified, and the extremity of said finger is made to project beneath the outstanding flange formed by the seat 3. Owing to this construction, the cover 4: can be removed only by first raising that portion of its edge beneath which the hook 8 is mounted. In order to free the hook 8 from engaging with the lip 10 and raise it from the position which it normally occupies, due to its own weight, a key 13 is employed having a pronounced bend at its middle portion and provided at one extremity with a hook 14. This key is adapted to conform to the slot 5 formed between the cover and the neck portion of casing. By passing the hook end of said key through the slot 5, the hook member 8 may be engaged by the hook 14, and the hook may thus be drawn to the position indicatedin dotted lines in Fig. 2. By then exerting a downward pressure upon the upper end of the key, the middle portion thereof is made to form a fulcrum, resting upon the outer ed 'e of the slot 5, and the key acts as a lever to raise the hook supporting edge of the cover. In order to guide the key 13 in the proper direction when it 1s passed through the slot 5, a panof lugs 15 are extended downwardly from the under surface of the cover at a pointadjacent to decrease the possibility of their being broken off. The channel 6 is provided in order to permit a chisel or some other form of lever to be driven in between the cover and its seat, in order to pry the cover loose in case it becomes rusted or frozen into place.
The. invention is presented as including all such changes and modifications as come Within the scope of the following claim:
What I claim is: p
The combination With a sewer clean out casing having a key receiving recess, of a diametrically opposite to the guide projections and normally. engaging the flanged PIOJBCUOD. of the casing, said hook having n dependlng key recelving portion.
In testimony whereof I have slgned my name to this specification in the presence of two subscribing Witnesses. v
