i Letters Patent No. 109,422, dated November 22, 1870.

IMPROVEMENT IN COAL-HOLE COVERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all/whom it may concern:

Be it known that I, LEWIS A. Kumkum', of New Haven, in the count-y of ,New Haven and State of Connecticut, have invented anew and useful Improvement in Covers for Coal-Holes and Fastenings; and I do hereby declare that the following is a full 'and exact description of the same, reference being hadto the accompanying drawing and to the letters of reference marked thereon.

Figure 1 is a section of my improvement, showing the legs thrown outward operating upon the wall.

Figurcf.. is a section, showing the legs held together ymy inyention, I will proceed to describe the construction andoperation ot' the same with reference to the accompanying drawing and the letters of reference marked thereon. i

A represents the cover made to lit over the aperture in the sidewalk, wit-l1 a flange, B, upon the under side., to prevent the said cover from being displaced byany lateral pressure that may he brought to bear upon it.

C and D are two spring bars or legs extending downward from the center of the cover, to which they are held in any convenient way, so that they be firmly fastened to the same. p The legs C and I) are provided with feet E, placed at their lower extremities and turned outward, either at right angles or slightly hook-shaped, as may be found most effectual inv grasping the wall.

Upon the inner portion ot' the-leg C, lnear the foot E, I place a hasp,F, and correspondingly situated upon the leg l) I placel a hook or staple, G. The object of this is that, when the two legs C and D are drawn together so that the feet E will not strike the unison-work, they may be hooked together by means of the said hasp and staple, and held as shown in fig. 2, so that the cover may be removed.

When the cover is replaced the hasp is forced out of the staple, and the spring of the legs .forces them outward until the feet E strike the lower side of the wall, as shown in iig. and, when thus fastened, the cover cannot bev pried olf from without; for whether the feet are curved 'or made at right angles with the leg, theirextremities will hear first upon the wall, and thus prevent them from slipping.

The advantage which my improvement has `over others of this class is that it may be adapted to any common cover now used without` altering or making any change-inthe position or size of the hole.

Having thus fully described my invention,

What I claim as new and useful, aud desire to secure by Letters Patent, s The spring bars C and I), when applied t0 a coa-lhole cover, and provided with a hasp and staple, F G, in the manner and for the purpose substantially as herein specified. v

This specification signed and witnessed this 8th day of June, 1870.
