HENRY P. FEISTER, OF PHILADELPHIA, PENNSYLVANIA.

PRINTERS CHASE.

SPECIFICATION forming part of Letters Patent No. 451,923, dated May 12, 1891.

Application filed July 2, 1889. Serial No. 316,347. (No model.)

To all whom, it may concern:

Be it known that I, HENRY P. FEIsTER, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Printers Chases, of which the following is a specification.

My invention has reference to printers chases; and it consists of certain improvements which are fully set. forth in the following specification and shown in the accompanying drawings, which form a part thereof.

My object is to form 'a chase of, a series of pieces, which are united together in such a manner that While imparting all the neces sary strength they can be readily and cheaply repaired in case of breakage, and the repaired chase is in all respects as strong and perfect as in its original condition. lVith my improveinent a repaired chase would not be discernible from one which never required repairing.

In carry-'ing out my invention I forni the chase of Wrought-iron or steel bars and corner-pieces, the latter being so shaped and locked or secured to the ends of the bars that a perfect, strong, and yet replaceable corner is obtained. In constructing such a chase the invention.

joints should be made so that the bars forming the rectangle cannot shift in any direction, and it is most preferable to form the inter-right-angled corner in the corner-piece, as this is the place where the rupture usually occurs in practice in most chases. Furthermore, by putting the right-angled corner in the removable corner-piece the same may be cheaply formed. I prefer to form the cornerpieces of phosphorbronze because of its great strength.

Referring now to the drawings, Figure 1 is a plan view of a chase embodying my invention in its preferred form with a portion of one corner broken away. Fig. 2 is a sectional elevation of same on line :n 00. Fig. 3 is a perspective view of one of the corner-pieces removed. Fig. 4 is a plan view of a corner of a chase embodying a modified form of my Fig. 5 is a cross-section of same on line 'y y. Fig. 6 is a plan view of acorner of a chase, illustrating still another modification of my invention, and Fig. 7 is a side elevation of the same.

A are the side and end barsv of the chase, I

formed with transverse grooves f on each face.,

The line of juncture of the webs F with the corner portion B forms oblique shoulders G G,

'and leaves the right-angled corner-notch b, as

shown.

In the constructions of chase shown in Figs. l to 5 the side and end bars A are made in pairs, and are preferably riveted together at K. These bars on their ends are beveled off ontheir outer edges to t against t-he oblique shoulders G, and are also shaped upon their adjacent surfaces at the ends withtransverse notches to receive the webs F and fit into the notches f thereof. (See Fig. 2.) When the side'and end bars are secured to the cornerpieces, screws or rivets H are passed through the said pieces and bars on the line of juncture at the shoulders G, and these screws or rivets perform the duty of holding the parts together in the length of the screws or rivets, and also of preventing any shifting of the bars on the corner-pieces along the line of the shoulders G. 1n large chases it is desirable to strengthen them by cross-bars, and also provide means for properly clamping or Wedging the type in place by the oluoins, which require a support against which to press. In adapting such cross-bar to my chase I make the bar C with tenons c on the ends, which are received in slots c in the side bars A, Figs. l and 2. rlhe ends of the cross-bar C are received in notches E on the inner faces of the side bars, and this with the tenons prevent any displacement of the cross-bar. The side bars A are also tied to the cross-bar C by riv ets D.

In the modification shown in Figs. 4 and 5 I have the same construction as shown -in Figs. l, 2, and 3, except that the grooves fin IOO the eorner-pieees are omitted und rivets I substituted in lieu thereof. It is elem' that in these various Constructions the bars A may be in single thickness in place of being formed of two flat bars riveted or serewed together; but that would be more expensive to oonstruet. In either oase the ends of the bars are formed with recesses extending laterally into them and adapted to receive the laterally-projecting webs of the corner-pieces. The Obliquity of the shoulder G makes it eet as a looking-joint. The Corner-pieces are preferably of phosphor-bronze.

In the inodiieetion of myinvention shown in Figs G and 7 the webs having the notches f are formed upon the bars A, and the Cornerpieee B is inadein halves or two parts formed to receive the web F and fit into the notches f, and the two parts of the corner-piece are clamped together by screws or rivets Il over the web F.

Vhile Iprefer to make the chase of the general construction herein set out I do not limit myself to the details, as they may be l Chase, Consisting of the part B, having two webs F, arranged et an angle to each other and formed with transverse grooves f, and the oblique shoulders G.

In testimony of which invention I have hereunto set my hand.
