These devices will, howand then specifically pointed out in the claims ever, be so constructed that they may be dis- 5 hereunto appended. connected from the cover, so as to permit the In the accompanying drawings, in which same when desired to be moved from its fixed 5 like characters of reference indicate the same position before referred to--that is, for inparts, Figure 1 is a side elevation of the imstance, from the position shown in Figs. 1 to proved casting-box with the parts in position 3 to the position shown in Fig. I. In the particular form of the devices illustrated they include two radius-bars 16, which are pivoted on the cross-bar 12. These bars 16 carry at their forward ends latches, which may be also widely varied in construction. As shown, (see more particularly Figs. 5 and 6,) these latches consists of stationary jaws 17, which are secured on the end of the bars 16, this screw construction enabling the latches to be exactly adjusted. Set-nuts 26 may be provided to maintain the jaws 17 in adjustment. Cooperating with each jaw 17 is a hook 19, these hooks being located between prongs on the upper part of the jaws 17 and being mounted on short shafts or rods 20. The hooks 19 are arranged to embrace a rod 18, which is secured to the back of the cover, the latches being thrown forward by means of suitable coiled springs 21. (See Fig. 6.) In the normal position of the cover, therefore, it is firmly connected to the radius-bars 16 by means of the latches, the bars and latches serving to maintain it in the substantially vertical position before referred to. hen it is desired, however, to swing the cover from the position shown in Fig. 1 to the position shown in Fig. 4, the latches are disconnected, after which the cover may be swung forward. The latches are preferably so arranged that they will automatically reengage when the cover is swung back to its normal position. In order to effect this, in the preferred form of the construction supports 25 are provided, which are secured to the shaft 12, the ends of these supports taking under and supporting the radius-bars 16. These supports are so positioned that when the cover is swung from the position shown in Fig. 4 into the position shown in Fig. 1 the rod 18 will strike the ends of the hooks 19, said ends being beveled, so that the pressure of the bar 18 thereagainst turns them on their pivots and allows the bar to pass under them, after which they are thrown down into operative position by means of the springs 21. Coiled springs 23 are or may be provided to ease the downward movement of the radiusbars and latches when the cover is disconnected.

Means are preferably provided for locking the jaws of the latches. These means may be of any suitable description. As shown, each latch is provided with a pivoted dog 22, which is arranged to engage a suitable groove or notch in the rear end of each jaw 17. These dogs 22 may be arranged so that they will rest upon the top of the latches, as shown in Fig. 4, when the latches are disconnected from the cover, their weight, however, not being sufficient to raise the latches. hen, however, the latches are raised by the impact of the rod 18, the dogs will be automatically thrown down into the position shown in Fig. 5, thus preventing any accidental disengagement of the jaws from the rod 18.

Means are preferably provided for controlling the movement of the cover, which means may be of any desired construction. As shown, a counterbalance 27 is provided, said counterbalance being connected to a lever 28, which passes through a fulcrum-block 29, pivoted on the cross-bar 12. The upper end of this lever 28 is connected by a chain 30 to a projecting piece 31, secured to the upper part of the cover, preferably by attaching it to a bar 32, which crosses the cover. The cover may also be provided, as shown, with handles 33, which assist in raising and lowering the same.

In order to insure that the cover when lowered, as shown in Fig. at, into the concavity of the body is in close operative contact there'- with, an additional clamping device may be provided which forces the two parts together. This clamping device may be of any suitable form; but, as shown, it consists of a pair of swinging clamps 34, provided with the usual wing-nuts, such clamps engaging, when they are in use, with slots in the ends of the crossbar 32 before referred to.

hen the invention is embodied in the type of box illustrated in the Hall and Hall application before referred to, a brace 40 may be provided for supporting the box in its hori- Zontal position, said brace being thrown into and out of operation by means of a handle 35, operating through a cross-shaft 36. Similarly, also a toggle mechanism. part of which is indicated at 37, may be used for forcing the parts of the box together. Furthermore, if desired, water maybe caused to circulate through the cover of the box by means of inlet and outlet pipes 50 and swinging pipes 17. So, also, the parts of the box may be moved away from each other by means of cams 13, the movement of which is effected by means of sprocket-wheels 4C5 and a chain 541, rotated by a crank 46.

The constructions here referredto are fully described in the pending application above identified, and reference is made thereto for a full description thereof, it being unnecessary, so far as the understanding of the present invention is concerned, to fully describe these features in this application.

Changes and variations may be made in the details of construction herein shown and described without departing from the invention. The invention is not, therefore, to be limited to the specific details of construction shown and described.
