UNITED STATES PATENT GEEICE- y LOUIS G. CHAPUT, OF NEW YORIL-N. Y.

IMPROVEMENT 1N PRINTERS cHAsEs.

Specification forming part of Letters Patent No. 139, 542, dated June 3, 1873; application ed May 13, 1873.

To all whom it may concern:

Be it known that I, LoUIs GEORGE OHAPUT, of the city, county, and State of New York, have invented a new and useful Improvement in Printers Chase; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming a part of this specification, in which drawingv Figure 1 is a plan view of my improvement. Fig. 2 is a section in the lineman of Fig. 1, showing a modification in the form of the joint `between the outer cha-se and the frame of the inner chase.

.Similarletters indicate corresponding parts.

This invention relates to av printers chase; and consists in an inner chase adapted and arranged to be placed inside of an ordinary chase, so that the latter can be used, when combined with the inner chase, for printing' cards and doing other small Work, and most of the furniture and quoins heretofore required in using au ordinary chase for small work are dispensed with. My invention is meant to gain economy in printing by enabling one to dispense with most of the furniture and quoins now required, and yet use a chase of the full capacity of whatever press rone is working, without changing the press or the chase when printing from small forms. My improvement accomplishes this result in a simple and inexpensive manner by supplying a supplemental inside chase which is provided with arms that are fitted within the main chase in such a manner as substantially to form therewith a single structure, the ends `of the arms interlocking with the angles of the main chase, so that the inner or supplemental chase is both centered and rigidly held in the main chase.

The letter A designates au ordinary chase, and B the inner or supplemental chase above mentioned. The chase B is provided at its corners with arms U C C G, which interlock with the angles D D D D of the chase A, as shown in the drawing, so that the combined apparatus is substantially united in one, so far as is necessary for the printing process. The joint, at the points of contact between the arms C and the anglesof the main chase, is so made as to allow the main chase A to be lifted and removed without .disturbing the shown in the drawing, the angles ofthe main .i chase being beveled on the under side to correspond thereto, or the arms can be provided with rabbets which shall tit into suitable recesses made on the under side of the main chase in its angles, or the parts may be interlocked or connected in. any other convenient manner. The supplementary chase can be provided with permanent wedge-shaped strips of furniture, E, as here shown, when iirst made, or can, if preferred, be left with straight sides.

Supplementary chases B, for forms of different sizes and shapes, can be provided according to my invention, their arms being arranged in each case to tit within the anglesof the main chase, so that a job printer having a chase, A, of full size for the capacity of his press, can, with the aid of my invention.l make use of such press and chase for small forms, and forms of various sizes and shapes, with only such furniture andquoins as are necessary to lock up the form in the inner chase B, thereby saving much` expense and outlay of capital, as well as time, and increas ing the capa-city of his office.

What I claim as new, and desire to secure by Letters Patent, is-

The supplementary or inner chase B provided with arms C, arranged to interlock with the angles or sides of the main chase A, substantially as described. Y

This specification signed by me this 21st day of April, 1873.
