THOMAS \V. MORGAN, OF OAKLAND, CALIFORNIA.
VENTlLATING lVlAN=HOLES FOR SEWERS.
SPECIFICATION forming part of Letters Patent No. 388,993, dated September 4, 1888.
(No model.)
To all whom it may concern.-
Be it known that I, Tnonas \V. MORGAN, of Oakland, Alameda county, State of Galil'ornia, have invented an Improvement in Ventilating Man-Holes for Sewers; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to a means for ventilating the manholes of sewers; and it consists of a supplemental line or chimney built in the wall of the vertical manhole and connected therewith at or near the bottom of the flue, and an opening through the side of the manhole curve or cover communicating with the upper part of the flue, together with a lip upon the inside of the curb or cover below this opening, and a pan or cover resting upon the lip and closing the main opening and causing the curreutof air from the sewer to go through the line; also a pan to catch all dirt, sticks, &c., which may fall through the open ings in the top cover.
Referring to the accompanying drawings for a more complete explanation of my inven tion, Figure 1 is a vertical section of the man hole curb and supplemental chimney, taken through A B of Fig. 3. Fig. 2 is a vertical section taken through 0 D of Fig. 3. Fig.3 is a. horizontal section taken through E F of Fig. 1. Fig. 4 is the top view of the curb and extcnsioucovcr ol' the supplemental chimney.
A is avcrtical chimney or man-hole extending from the street-surface down to the sewer B, which passes beneath and in comi'nunicaiion with its lower end. The upper part of the man-hole is finished off by a circular iron curb, 0, having a perforated cover, D, which lies flush with the street-surface.
In my invention I have built a supplementa-l vertical flue or chimney, E, at one side of and parallel with the man-hole. The lower end of this line connects with the man-hole at some convenient or desirable point between the top and bottom, and the opening is covered by a lattice or grating, F, as shown in Fig. 2. The cover D for the man-hole has an extension, D, at one side, which forms a cover for the supplemental flue, and a hole or opening, G, is made in the side of the cylindrical curb or cover, which communicates with the upper end of the supplemental flue.
Around the lower inner edge of the main cylindrical curb is formed a projecting lip, H, upon which the edges of the metal pan or cover I rest. This pan has an eyeholt or haudle, K, by which it may he lifted out when the perforated cover is removed from the curb, and when itis in place it serves to prevent sticks and dirt from falling down into the manhole and clogging thesewer.
The supplemental flue or passage may be filled with charcoal or other disinfectant:- substances, and the gases arising from the sewer passing up the man-hole will enter this fine through the lattice or grating, and thus rising to the top will again return into the curb above the pan I, through the opening G, and from thence will escape into the open air.
By this construction I provide a free escape for the gases arising from the sewer, and, if desired, a means for purifying them before their escape, while by means of the cover with in the curb I prevent everything falling in, to form an obstruct-ion in the man-hole.orscwer.
Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-
1. Thevertieal man-hole having the supplemental flue formed parallel therewith, and the curb 0, having the opening G, said supplemental flue having its lower end leading into the man-hole and its upper end in communication with the passage G, in combination with a close pan or cover'at the bottom of the curb below the opening G, substantially as herein described.
2. Thevertical man-hole,asupplemcntal flue built in the side wall thereof, and the curb C, said suppelmental flue connecting with the man-hole at its lower end and with the space in the cylindrical curb at the upper end and being filled with charcoal or other disinfectant, in combination with the close pan or cup fitting upon the ledge or lip around the bottom of the curb, the perforated cover fitted to the curb, and the extension at the side of the curb with its supplemental cover, substantially as herein described.
In witness whereof I have hereunto set my hand.
THOMAS W. llIORGAN.
