retaining-spring removed from the box. Fig.V

3 is a longitudinal section through the lid, spring, and portion of the box, showing the lid in closed position. y

A is the axle-box, and B is the lid; C, the spring; D, the pivot-bolt. y

The spring is connected tothe lid at about the middle point of the length of the latter, and is bowed up from its connection thereto until it overhangs the line of the pivot of the lid to the box, so that the pivot-boltD passes through the eye C in the spring and through the eye B in the lid and bindsboth together to the box. The bolt D will be screwed into the box until the spring has the desired tension-thatis, until it holds the lid as rmly as necessary onto the box. In the drawings I have shown my preferred method of connecting the spring to the lid, which consists in making through the lid transversely at about the middle of its length the slot B2 and striking the meta-l at one side of said slot upward and at the other side downward, so that the spring, which is a flat steel bar, may be inserted through the slot, and having the end which has the eye CVcarried down toward the plane of thelid. The spring Willbear against the under side of the lid on the side of the slot remote from the pivot and on the upper side of the lid on the side of the slot toward the pivot, and thereafter during further tilting or bending of the spring toward the plane of the lid it will operate as rigid with the lid to react against such movement.

The connection of the spring to the lid may be varied considerably, and I do not therefore limit myself strictly to the form of connection shown; but the connection should be such as to make it act as if rigid with the lid where it is in contact therewith when its free end is pressed toward the latter-z'. e., for the purpose of reacting against such pressure-and it should also be stopped laterally on the lid, so that the edgewise swinging movement of the lid in uncovering the box shall carry the spring positively with it.

It is of considerable importance that the spring should be of a different pieceof metal from the lid, because the spring should be of steel in order to have the requisite capacity for receiving tension, while the lid is preferably of wrought-iron or rolled-iron plate, so that it may be readily hammered perfectly liat, or so as to seat on the margin of the box .and make a reasonably close tit at such seat.

Steel-plate cannot readily be brought to this condition by hammering while cold, because of its elasticity. y

` The advantages of this lid and spring, therefore, over other forms now in use are that while having only one point of bearing upon or contact with other attachment to the lid,.that point being relatively quite remote from the pivot toward the other end, the tension ofthespring is exerted much more advantageously upon the lid and holds it much more securely than if the pressure were exerted near to the pivot, as in some other forms; and this result is attained as perfectly as if the spring were made to bear upon or be secu red to the lid at two points on opposite sides of the pivot, as in certain' known forms. An advantage of the mode of attaching the spring to the cover over any mode which should constitute a permanent attachment, as riveting, is thatit may be removed and a new spring substituted readily and without taking the lid to the shop for the purpose and without mutilating the lidin any way, and also that the expense of any more permanent attachment is avoided; but a further advantage, which is specially related to the other features of construction and mode lid,'as by rivets or bolts or by any otherV Ioo V v ml methodwhich would absolutely prevent longitudinalmovement at its pointV of attachment, either the cover or the spring would have to have the eye through which the pivotbolt passes elongated, because if the two eyes werein line before the spring had been drawn dow-n at all they vwouldv be out ofi line after the spring had been fiexed, as necessary'for its tension, because in such flexure the eye would advance substantially in an are about the point of attachment of the spring to the lid. This attachment being such that the spring can bedriven longitudinally, even after it is under tension, it' is not necessary t'o elongate either eye, because the spring-would be first inserted in such position as to bring the two eyes- C and Bf properlyl coaxial with. the-bolt, and=asthe bolt is tightened and the' eye-C approaches the lid the spring will at irstby thattightening action be forced longitudinally throughithelid, and after it has become too tight' to receive such motion: vby; the mereftighteningof;` the'bolt-,anocc'asional tap of the hammer on tlre end-ofthespringas the bolt is tighten'edwillcause-ittomove sufiicientiy to'lceep'its'eye C in linewith the eyeD'.
