DANIEL GAILEY, OF PHILADELPHIA, PENNSYLVANIA.
SPECIFICATION forming part of Letters Patent No. 786,203, dated March 28, 1905.
' Application filed October 1, 1904. Serial No. 226,823.
To (Ml 111700717 it may concern:
Be it known that I, DANIEL GAILEY, a citizen of the United States, residing in Philadelphia, Pennsylvania,have invented an Improved Cover for Drain's, Vent-Boxes, \Vashpaves, &c., of which the following is a specification.
My invention relates to covers for manholes, drain-boxes, washpaves, vent-boxes, greasetraps, &c.; and it consists in constructing such cover so that mischievously-inclincd persons will be unable to damage or clog the passage or opening closed by said cover or render it unfit for use by passing sticks and other similar articles into the same.
My invention is fully shown in the accompanying drawings, in which Figure 1 is a plan view of one form of cover embodying my invention. Fig. 2 is a sectional view of the same, taken on the line a a, Fig. 1. Fig. 3 is a plan view of anotherform of cover embodying my invention; and Fig. 4 is a sectional view of the same, taken on the line 7) b, Fig. 3.
The cover forming the subject of my invention is more particularly applied to vent-boxes for house-drains in use generally and disposed in the sidewalks of city streets near the curb. These covers are provided With holes for ventilation, which also permit drainage of surface-water, and these holes present to all mischievous children anopportunity rarely neglected of passing sticks and other articles into the boxes guarded by such covers. The extent to which this practice is carried on in some sections of large cities is such as to necessitate the breaking and excavation of the sidewalk and the removal of the box inclosing the trap and the subsequent placing of a new boxin place. In washpaves the drainage-pipe is quickly clogged up, and in all places Where drainage or ventilating covers are employed they are soon clogged up by sticks intentionally placed therein or by debris carried into the same by the natural flow of surface-water. By my invention I propose to overcome this condition and prevent the insertion of sticks and other articles tending to clog the drains and to fill up the gas and water valve-boxes.
In Figs. 1 and 2, 1 represents the metal frame or end for the wooden trunks or boxes placed around vent-boxes, and 2 the cover for such box applied to the frame 1. This cover is supported by the usual ledges 3 and when set in place is secured by the screw 4. It is provided with apertures 5, and depending from the under side of the plate are a series of ribs 6 cast integral therewith. These ribs carry lateral projections 7 and 8, which may extend the full width of the box and are disposed .direetly beneath the apertures, serving as a means of preventing the direct through passage of sticks or similar articles, but ottering no obstruction to the passage of water or air. The projections 7 guard the projections 8 and prevent the passage at an angle of a stick or similar article, and these two sets of projecting portions are so disposed that they form an eifective barrier. The apertures 5 of the structure shown in Figs. 1 and 2 are oblong in shape, and in Figs. 3 and L I have shown a structure having circular apertures 5. The character of the aperture is entirely immaterial, however. In this form of the cover there is a slight difference in the shape of the projections, both sets 7 and 6" having rounded faces. The effect, however, is the same and either cover may be used interchangeably.
Having thus described my invention, I claim and desire to secure by Letters Patent- 1. In a cover for drains, vent-boxes, washpaves and the like, the combination of the up per or main surface-plate having apertures, and reversely-disposed projections arranged beneath the same and forming a zigzag passage.
2. In a cover for drains, vent-boxes, washpaves and the like, the combination of the upper or main surface-plate having apertures, ribs disposed on the under side of said plate, and two sets of lateral projections carried by said ribs and guarding said apertures.
3. In a cover for drains, vent-boxes, washpaves and the like, the combination of the upper or main surface-plate having a series of apertures, and a series of reversely-disposed project-ions arranged beneath said plate and forming zigzag passages with respect to the apertures in the same.
4. In a cover for drains, vent-boxes, washpaves and the like, the combination of the upto this specification in the presence of two subper or mam surface-plate having apertures scribing Witnesses.
depending ribs disposed on the undorsurfaoe of said plate, and lateral projections extend- DANIEL GAILEY' 5 ing on both sides of said ribs and guarding Witnesses: 4 said apertures. MURRAY C. BOYER,
In testimony whereof I have signed my name WILLIAM F. BEATON.
