REVOLVING TYPE-BED.

SPECIFICATION forming part of Letters Patent No. 228,680, dated June 8, 1880. Application ined April 21, Isn.

To all whom t may concern:

Be it known that I, JOHN W. RICHARDS, of the city of Newark, county of Essex, State of New Jersey, have invented an Improvement in Revolving TypeBeds, of which the following is a specification.

The said invention is illustrated in the accompanying drawings, which represent, in-

Figure l, a plan view ofthe type-bed; Fig.

1o 2, a transverse sectional elevation of the same on line y of Fig. l; Fig. 3, a transverse sectional elevation of the same on linez of Fig. 1, showing the lconstruction of one of the ends; Fig. 4L, a longitudinal section of one end` of the type-bed on line x of Fig. 2, showing the bottom pieces and column-rulesin elevation; Fig. 5, an end view ofthe locking-bar, and Fig. 6 plan view of one of the bottom pieces.

Heretofore the column rules of revolving 2o type-beds have been provided with feet adapted to enter transverse holdin g-grooves sunk in the face of the bed, the said grooves being filled with sliding blocks between the points occupied by the rules, so as to provide a comparaz 5 tively smooth surface for the columns of type to rest upon; but in such construction it is found, in practice, that the loose type at the sides ofthe columns sometimes slip down between a foot of the column-rule and the sliding piece in the groove, and thus prevent the type from being moved up and drawn in the space between two column-rules in making up the form, and also prevent the body of types between the column-rules from being locked up lirmly.

The object of the presentiuvention is to avoid the joint at the Sides of the columns, where, especially in curved forms, the type are apt to be loose, and thus easily drop down; and the 4o invention consists in a construction of parts which brings the joint between the bottom pieces which separate the column-rules at a point between the same where the type are more firmly held.

Rotary type-beds are constructed of a segment of metal, whose base-plate 7 is curved transversely on its outer face to an arc a little less than the diameter of' the type-cylinder which is to receive it, and provided with 5o flanged ends ll and sides 20 l2.

Each column-rule 2 is fiXedly held in a bottom piece, 3, which extends the whole length of the bed, and is curved to correspond with the face of the base plate 7. These bottom pieces, 3, are of such width that when two are brought together the space between the rules they support is just equal to the width of a column of type. In order to hold them in place firmly upon the base-plate 7, they are provided with feet 4, projecting from their under 6o surfaces, which feet, having lateral projections l l, are adapted to enter rabbeted transverse grooves in the base-plate 7 of the bed and slide therein. There may be two or more of these feet 4, according to the length of the column, and in order that their extreme ends may be secure they are provided with tenons 13, which enter rabbeted grooves 8 in the ends of the type-bed. Two of these tenons are provided (see Fig. 6) in order that a recess may 7o be formed between them to permit the said bottom pieces to pass the jaws 17, which project from the end plates, for a purpose to be explained, and enter the grooves 8.

The bottom piece, 10, which supports the column farthest from, and the bottom piece, 5, nearest to, the locking side of the type-bed, are so constructed that they may provide on one side of the rule they carry a surface suflicient to support the entire width of a column ot' 8o type-while on the other side they furnish a support for but one half of the width of a column of type, the other halt' of said column being supported by the next adjacent bottom piece. Between these bottom pieces 5 l() the 8 5 columns (to any number) are supported vby bottom pieces whose surfaces each side of the rules they support are equal to one-half' the width of a column of type.

In making up a form in this improved type- 9o bed, we will suppose the first or inside column is set up O11 the bottom piece, l0, between its rule 2 and the side l2 of the bed. A second column of type may be then placed between the rule carried by the bottom piece, l0, and that carried by the bottom piece, 3, and so O11 until the type-bed is lled, except with its last or outside column of type, the intermediate columns of type, or those between the inside and outside columns, being supported on bot- Ioo tom plates whose joining-seam is midway, or nearly so, between the column-rules. rlhese bottom plates are entered vertically past the jaws 17, andare slid laterally in the rabbeted grooves S, their feet 4t passing into the transverse groove 6 in the bottom plate, 7, of the type-bed. To provide for their thus being entered, the end plates, l11, are cut away or recessed, as at 15, and the overhanging edges ot' the transverse orooves 6 are cut awav see dotted lines, Fig. 1) for a distance at the entrance side which is equal to the length ofthe l'eet el. of the said bottom plates.

The ledge necessary to support one side of the outside column of type resting on the bottom plate, 5, is at'torded by one side ot'- th'e locking-bar 9, which is ot' such a thickness as to extend upward nearly type-height. rllhis locking-bar is provided with tenons 14, the bottoms ol" which are extended by projections 1S (see Fig. 5) ot' a thickness adapted to iit into the groove 8 and under thejaw 17. The length of the projections 1S is such as will )erniit them to enter the recesses 15.

The various parts having been placedin position with the columns ot' type supported by them, lateral pressure is applied to the locking-bar 9, which forces the bottom pieces, 5 3 1U, tightly together and toward the side plate, 12, thus compressing the columns of types between the rules and side supports and holding them rmly in place.

In this invention the column-rules areneither provided with 'li'eet entering' the transverse grooves in the bottom ot' the bed nor with tenons entering the grooves in the ends of the bed, which construction has heretofore been given them, so that they would perform the double 4function oi' aiding-in holding their place in the bed and of clamping the types in place. ln

the present construction they are subjected to no strain save that of holding the types in place. l

The means herein illustrated for applying the pressure to the side bar, 9, necessary to lock up the 'form is sct-screws 19, tapped through the side plate, 20; but, as will readily be understood, the common means for effecting the locking up ot forms may be used. Among these means may be enumerated quoins and wedged faced side-sticks, one of which is driven longitudinally upon the other by a screw or rack and pinion.

Each separate column may be adjusted longitudinally by pressure applied to its end either by screws or wedges.

It is not essential that the line of division between the bottom plates shall be centrally between the column-rules, so long as it is far enough from the edge of the column of type as to support the types where, being a compact mass, they are supported on all sides, and therefore lack the tendency to slip one away from the other, as is the case with the types at the edge of a column of types.

The type-bed thus constructed may be xed upon the type-cylinder in any approved manner.

WV hat therefore is claimed is 1. A type-bed the bottom plates whereof support fxedlythe column-rules at a distance from their edges, substantially as described.

2. rlhe combination of the bottom plates, having column-rules attached to their faces and provided with Han ged feet, with the baseplate having rabbeted grooves 6, substantially as described.

3. The combination of the bottom'plates, having column-rules attached to their faces and provided with hanged feet 4 and tenons 13, with the base-plate having rabbeted transverse grooves (3 and rabbeted grooves 8, substantially as described.

In testimony whereof I have signed my name to this specification in the presence ot' two subscribing witnesses.

JOHN W. RlCHARDS.
