sTEREoTYPE-Box.
SPECIFICATION forming part of Letters Patent No. 466,366, dated Januaryv 5, 1892.
Application filed September 7, 1891E Serial 110.404,945. (No model.)
To all whom it vmay concern:
Be it known that I, CHARLES S. PARTRIDGE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Stereotype-Boxes, of which the following is a specification.
This invention relates to devices for automatically locking the cover of a swinging stereotype-box when the box is turned into the vertical position ready for pouring and for automatically unlocking the same when the box is turned into thehorizontal position. The nature of the devices which I employ for this purpose is fully shown in the accompanying drawings, and they consist of segments pivoted to the box, catches or projections upon the box-cover, adapted to be engaged by hooks carried by the segments when the box is moved into the verticalposition, and a stationary segment-rack with which the swinging segments intermesh andV by which they are actuated in locking and unlocking the box.
In the drawings, I show, at Figures l and 2,
side elevations of a casting-box provided with my improved locking devices, Fig. 1 showing the box in the horizontal and Fig. 2 ,in the vertical position. Fig. 3 is a detail section of one of the locking projections upon the cover.
In the drawings, A represents the supportingframe; a, the trunnionsupon which the box swings; B,the support for the cover when open; C, the stationary rest supporting the box at one end when' in the horizontal position, and D d the vpivoted elbow 'tripping-lever for releasing the box when it is to'be tipped up for pouring and for supporting its end when lowered.
E is the box, and F its cover, hinged together with hooks J, which, when the box is tipped,
are moved into locking position, with the laterally-extended ends of the catches K secured in the cover of the box and extended so as to lap over the side of the box and into position where they can be caught by the hooks J. Duplicates of the rack, the segments, the hooks, and the catches are provided upon'the farther side of the box, or, in lieu of duplicating the segments and rack,
there may be provided upon the farther side the pivots should extend across the box and the segments shown, and likewise the hooks at the farther side must be made fast thereto, so that the power derived from one setof seg- `only the hooks and catches; but in such case 6o ments and the rack can be used to operate the hooks at both sides of the box. The catches K are adj ustably secured in dovetails in the side frame of the box-cover and may be adj usted by the screws m', bearing upon the cover andheld'in the adjusted position by 7o the set-screws m.
The operation of the devices is as follows: Supposing the cover F to have been lowered preparatory to the making of a cast, thelever D is raised, thus removing from under the box the support cl, which maintains it in its horizontal position. The box now tips from the position shown at Fig. 1 to that shown at Fig. 2, and in this operation the segments H are moved to the position shown at Fig. 2. 8o
This movement brings the hooks J into a locking engagement with the catchesK, as plainly appears from Fig. 2. After the metal has been poured into the box and has cooled, it
is returned to the horizontal position, and
in this return movement the segments H are so actuated as to dissolve the locking engagement between the hooks and catches. The box is now free to be opened for the re` moving of the cast. The operation of locking 9o an d unlocking Yis entirely automatic and saves all necessity for the use of hand-operated clamps. Should the locking-surfaces of the hooks and catches become Worn, the wear may be taken up at any time by adjusting the s IOC type-box, of the segment-rack, the swinging segments meshing with said rack and pivotcd upon the box, the hooks joined to said segments, and the catches upon thc boX-covei` interlocking with the hooks, substantially as set forth.
2. The combination, with the tipping stereotype-box, of the segment-rack, the swinging segments meshingr with said rack and pivoted upon the box, the hooks joined to said segments, and the adjustable catches upon Io the box-covel` interlocking with the hooks, substantially as set forth.
