The tire box can be so nicely balanced upon its box-body has its interior of the usual curved 5o trunnions that the operation of swinging it form, and the cover Gfits between the sides of I00 the body, the said cover being hinged to the body by a hinge-rod 7, which passes through ears 8 on the cover and ears 9 on the box. The cover 6 is secured to the hinge-rod 7 by means of set-screws 10 orin any other suit-able manner. The body portion of the box is provided with lugs 11, which are engaged by a sliding bar 12, carried on the cover, the cover being locked to and unlocked from the body portion by sliding the said bar 12. The bar 12 maybe movedin any usual or desired manner. In the present structure it is shown as provided with racks 13, which engage pinions 1i on a shaft 15, suitably mounted in bearings on the cover of the box. The shaft 15 is provided with a handle 16, by which the shaft is rocked to slide the bar 12, and is also provided with handles 17, by which the cover and box may be swung from vertical to horizontal position, or vice versa. The box is also shown as provided with the usual side bars 18, by which the position of the matrix is controlled.

Extending across the frame from side to side is a rod 19, which carries stop-lugs and 21, the stop-1ug 20 serving to limit the movement of the box when it is swung into a hori zontal position and the stop-lug 21 serving to limit the movement of the box when it is swung into a vertical position, as will be apparent by comparing Figs. 2 and 3.

As has been stated, springs are applied to the cover of the box in order to assist in raising the same.

In the preferred form of the construction the hinge-rod is extended on each side of the box. Mounted on the extensions of the hingerod are arms 22, which are secured to the hinge-rod in any suitable manner, as by setscrews 23. The arms 22 preferably have integral with them collars 24, which extend along the extensions of the hinge-rod. The purpose of these collars is to increase the size of the rod, so that the central coil of the spring, to be hereinafter described, may be of larger size, and therefore more efiective. It is obvious that the collars may be independent of the rods or in some cases omitted altogether.

Coiled about the collars 24 are springs 25, said springs having their operating ends 26 connected to the arms 22 in any suitable or desired manner. In the construction shown the arms 22 are provided with screw-eyes 27, said eyes being adj ustably secured in the arms 22, so that the tension of the spring may be readily adj usted. The adjustment of the screw-eyes may be effected in any suitable or desired manner. In the construction shown the adjustment is effected by nuts 28. The other arm 29 of the spring may be secured in any suitable or desired manner. Preferably, however, it will be secured to the frame.

Various means may be used for effecting the connection between the frame and the spring. In the preferred form a plate 30, having a closed eye 31, will be secured to the frame by means of a pivot-bolt 32, which passes through the eyein the frame. By pivoting the plate 30 to the frame it will be seen that as the box swings from the horizontal to the vertical position the plate is free to follow the box and any bending orcrampiug of the arm 29 of the spring is avoided. The plates are preferably located so that the bearing-points of the arms 29 of the springs are opposite the centers of the trunnions on which the box is pivoted, as when the springs bear at these points they do not affect the balancing of the box. If desired, however, the plates 30 may be pivoted off the centers of the trunnions, as indicated in Fig. 7. hen so arranged, the arms 29 of the springs will have a slight tendency to cause the box to swing from its vertical to its horizontal position, or, in other words, will aid in swinging the box into its horizontal position after the casting has been made. Inasmuch, however, as the balancing of the box can be effected with extreme nicety through the trunnions alone, it is preferable to locate the pivot-plates as shown in the figures before referred to.

While it is preferred to secure the arms of the springs to the frame, as has been before de scribed, they may under some circumstances be otherwise secured.

lVhile the arrangement of the spring, which has been heretofore described, is an efficient one, it is to be understood that there are other arrangements and locations of the spring which are possible. The invention is not, therefore, to be limited to the particular construction which has been heretofore described, but embraces such other arrangements as have been referred to. The box is shown as provided with locking-arms 37,which are mounted on a shaft 38, the position of the shaft being controlled by a lever 39, having a handle 40. \Vhen the box is in its horizontal position, the end of the lever takes under a safety-rod 41 and prevents the box from being turned upon its trunnions when the cover is swung up.

What I claim is 1. In a casting-box, the combination with the body portion and cover, of a frame in which said parts are mounted to swing, a hinged rod connecting the cover and body portion and to which the cover is rigidly secured, said rod extending beyond the side of the box, a spring coiled around the rod, an arm rigidly secured to the rod and to which the operating end of the spring is secured, and means for connecting the other end of the spring to the frame.

2. In a casting-box, the combination of a body portion and cover, of a frame in which said parts are mounted to swing, a hinged rod connecting the body portion and cover and to which the cover is rigidly secured, said rod extending beyond the sides of the box, arms rigidly connected to the extending ends of the rods, springs coiled around the rod and having their operating ends connected to the arms and means for connecting the other ends of the springs to the frame.

3. In a casting-box, the combination with a bot y portion, of a cover pivoted thereto, a hinge-rod connecting; the cover to the body portion, the cover being rigidly secured to the hinge-rod, an arm rigidly secured to the hinge-rod, a collar extending from the arm, a spring coiled about the collar and having its v operating end connected to the arm,and means for connecting the other end of the spring to the frame, substantially as described.

4. In a casting-box, the combination with a body portion, of a cover connected thereto, a frame in which said parts are movably supported, a spring having its operating end arranged to exert a lifting moment on the cover and a swinging connection between the other end of the spring and the frame.

5. In a castingbox, the combination with a body portion, of a cover, a frame in which said parts are movably supported, a hinged rod connecting the body portion and the cover, the cover being rigidly secured to said rod, an arm rigidly connected to the rod, a spring coiled around the rod and having its operating end connected to the rod and a swinging connection between the other end of the spring and the frame.

6. In a casting-box, the combination with the body portion, of a cover, a hinged rod connecting the cover and the body portion, the cover being rigidly secured to the rod an arm rigidly secured to the rod, a spring coiled around the rod and means for adj ustably connecting the operating end of the spring to the arm.

7. In a casting-box, the combination with the body portion and a cover, of a frame in which said parts are mounted to swing, a hinged rod connecting the cover and the body portion and to which the cover is rigidly connected, an arm rigidly connected to the arm, a spring coiled around the rod, means for adjustably connecting the operating end of the spring to the arm and the swinging connection between the other end of the spring and the frame.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

LUTHER O. OROWELL.
