To all whom t may concern:

Be it known that I, AUGUST WV. KURZ, a citizen of the United States, and a resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vault- Heads, which improvements are fully set forth in the following specification.

This invention relates to improvements in structures of that class employed in connection with subterranean vaults for the purpose of controlling, each the entrance to the vault with which it is conjoined, such structures being commonly known as vault heads.7

The objects of this invention are to provide a structure of the character indicated which shall be simple and inexpensive as regards construction; durable, efficient and reliable in practical service; which shall embody features of construction insuring a novel operative relation between the main member of the device and the lid therefor; which shall be attractive in appearance, and which shall possess certain well-defined advantages over prior analogous structures.

The invention consists in the novel dis- I position and relative arrangement of the various coperating parts thereof, whereby the attainment of the above objects is rendered practicable; in certain combinations; and in certain details of construction, all of which will be specifically referred to hereinafter and set forth in the appended claims.

The invention is clearly illustratedin the accompanying drawings, wherein similar reference-numerals denote corresponding parts throughout the several views, and as to said drawings: Figure 1 is a plan view of a vault head embodying my said improvements, a portion of the keeper which I purpose making use of, being broken away to bet-ter disclose certain minor features of the construction, and the lid employed being partially displaced from the position it normally occupies in service. Fig. 2 is a central, vertical, longitudinal section, along the line a-a of Fig. l, the lid aforenamed being seated for service. Fig. 3 is a transverse section along the line b-b of Fig. l, the keeper above referred to being removed.

In a general sense my invention comprises a main member forming a man-hole, and a lid therefor, the latter spanning said man-hole, under normal conditions, and being at all times interlocked with said member, the interlocking relation between said lid and said cover being such as to permit the former to undergo bodily a displacing movement from the position it normally occupies 1n service.

In carrying out my invention, reference being had to the accompanying drawings, I employ a main member 3, forming a manhole for the structure as a whole, said member being provided with opposing, interior ribs 3 3, each formed integral therewith by preference, having a base flange 4, and, in this instance, being extended rearwardly to receive a keeper, 4. These several parts may be each readily produced from metal by the process of casting.

For spanning the man-hole of the device, I employ a lid 5, the same, in this instance, being illustrated as approximating the form of a grate. Under normal conditions the lid 5 seats at its opposite side portions on the ribs 3 3; and in order that its upper surface may register flush, or substantially so, with the upper edges of the member 3, the interior ribs 3 3" are depressed accordingly, each with respect to the upper edge of that portion of the member 3 along which it extends.

The lid 5 is provided at its rear with opposing, depending legs 5 5, which legs terminate, the former in a laterally projecting foot 6, taking under the rib 3', and the latter in a like foot 6', taking under the rib 3 the foot being in effect an outwardly projecting flange, the space between the flange and the side of the lid proper forming a groove for the reception of rib 3". The legs 5 5 are arranged, each at a point somewhat inwardly from the adjacent side of the lid 5, the feet 6 6 are accordingly overhung, each by a portion of said lid, and grooves 5 6, at the opposite sides of said lid, are accordingly 4formed to receive, respectively, the ribs 3 3. The legs 5 5 are respectively of sufficient width, and the portions of the lid 5 which overhang the feet `6 6 are respectively of sufficient extent, to

insure at all times and under all conditions a loosely interlocked relation between the lid 5 and the main member 3. Thus an interlocking effect is secured between the lid 5 and the member 3, and the arrangement and length of the ribs 3 3, respectively, are such as to maintain Athis interlocking relation between said lid and said member, under all displacing movement of the lid, in

the practical operation of the device as a whole.

The rear vertical portions of the member 3, forming the extension thereof which receives the keeper 4f', terminate upwardly at a.plane below the ribs 3 3,l to permit the adjustment for` service of the lid 5 with respect to the said ribs, and such adjustment ofv said Vlid is eected before the keeper 4: is aldjustd and fastened in position on the member 3, as will be clearly apparent from Fig. 2 of the drawings.

For the purpose of preventing full removal of the lid 5 from the device as a whole, as rearwardly along the ribs 3. 3, I employ the keeper t, which may approximate the form of a hood, such as ordinarily used inV this class of devices, and as illustrated in the drawings, or the same may take any other appropriate form rendered advisable bythe conditions involved in the practical installation of the device as a whole. provided with a depending lip 7, which is enlarged at its respective ends to form stops 7 7, (Fig. l), against which'the rear portions of the legs 5 5'abut, respectively, under tendency on the part of the lid 5 to move rearwardly, as from the position it is shown as occupying in Fig. 2V of the drawings.

' When taking the form of Va hood, the

, keeper l is provided, by preference, with the usual intake, as customary in structures of this class; and the same may be firmly fastened to the member 3 in any common and approved manner. In this connection,

, however, I have shown said keeper as being provided with a lateral eye-clip 8, the member 3 with an inverted socket 8, registering with said clip, a headed bolt 8 extending upwardly through the crown of said socket and through said clip, and a nut 9 on said bolt, above said clip and bearing downwardly on the latter. It will be Vunderstood that a plurality of clips 8, sockets 8, bolts 8 and nuts 9, may be employed substantially as indicated in the drawings.

When constructed as herein described, it is essential that provision be m-ade for the adequate lifting, in the irst instance, of the lid 5 bodily, or essentially the forward portion thereof, in order that said lid as a whole,

Vor essentially its forward portion, may

escape the front wall .of the member 3, and admit of being displaced forwardly, as tothe position indicated in dotted lines in Fig. 2; and to the attainment of this end suitable play is left between the feet 6 6 and the ribscoperating therewith, aforenamed, as clearly illustrated in Fig. 3 of the drawings.

While I have in my claims called fora w lid and keeper which together. span the manhole opening, a lid or keeper which should only substantially cover the said vopening would be within the intent of my invention.

The keeper 4 in this instance is It will be seen that the extent to which the free end of therlid may be raised depends upon the breadth of the feet and the width apart of the ribs. If the ribs are broad in comparison with the space between the ribs, then the cover can be tilted but a short distance before the upper andlower diagonal corners of the foot will come in contact with the upper and lower ribs, and prevent further tilting movement, but if the feet are narrow or the legs long, the lid would be free to be tilted to a much greater angle. Care must be taken, however, that if the lid is adapted to be raised to a considerable angle there be means to prevent any liability of the lid being angled out by a turning movement in a horizontal plane.

This will occur if the legs be narrow, henceA it is desirable that the legs have a wide contact surface parallel with the side of the head, if the lid is intended to be opened to a greater degree than just suiiicient to slide it.

Vhile I have shown and preferably use a lid which slides on the head away from the hood, yetI do not wish to be limited to a lid sliding in that direction, as without substantial change, except in proportion, it might slide within the hood, though I do not believe this to be the preferable construction.

Though I have illustrated my improvement in connection with the vault head of a catch-basin manhole it will be understood that the principle of my invention may be as well applied to the openings into other kinds of vaults or conduits, and whether the openings be small or lar e.

It will be seen t at my improved vault head is particularly well adapted for the purposes for which it is intended, andwfurther that the same ma be modified to some extent without materially departing from the spirit and principle of my invention.

Having thus described my invention what I claim and desire to secure by Letters- Patent, is:
