Patented July 20, 1937 UNlTED STAT TYPE BED Edd C. Oliver, Adrian, Mich. Application September 10, 1934, Serial No. 743,424 6 claims. (ci. 10iasm This invention relates to type beds andthe object of the invention is to provide a type bed having spaced parallel grooves and provided with type holding bars insertable in the spaced grooves to hold the type therebetween.

Another object of the invention is to provide a means for holding the type under pressure at Vthe base so that the type will remain in iixed position and cannot be readily moved in the normal printing operations.

A further object of the invention is to provide a type bed having spaced grooves therein into which type holding bars may be inserted to provide spaced parallel ribs between which rubber type may be mounted, the type being slightly Wider at the base than the distance between the adjacent sides of the type holding bars.

Another object of the invention is to provide a type bed in which sheet metal type holding bars may be inserted to hold the type, the sheet metal type holding bars being provided with yieldable flanges in order to rmly hold the type therebetween.

A further object of the invention is to provide a means for yieldably holding solid non-compressible type on a type bed in printing position.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawing in which- Fig. l is a plan view of a type bed embodying my invention.

Fig. 2 is an enlarged section taken on line 2-2 of Fig. 1.

Fig. 3 is a perspective view of the type holding bar which is inserted in the grooves of the type bed.

Fig. 4 is a sectional perspective showing a modied form of type holding bar for holding the type in position.

Fig. 5 is a similar section showing another modified form of type holding bar.

Fig. 6 shows the type holding barof Fig. 5 in inverted position.

Fig. 7 is a section showing the simplest form of type holding bar and groove.

The type bed maybe made of any suitable material, the cheapest form being laminated wood, fibre or solid wood as suggested in Fig. 2. This type bed l is usually rectangular in form and is provided with spaced parallel grooves 2 shown in Figs. l and 2. The type holding bar is shown more particularly in Fig. 3 and comprises a metal bar 3 having sloping sides which slope toward the center as shown. These bars may be equal in length tothe width of the type bedA and are, inserted in the grooves 2 as shown in Fig. 2. The grooves 2 are all equally spaced lengthwise of the type bed and the type holding bars may 5` intervening groove and the next size maybe one'r 1.0l

and one-half inches or two inches wide plus the width of the intervening grooves,` the various type being formed in multiples of the space between the bars plus the width of theintervening grooves. 1 V2in this case, the narrowest type 4, shown. in Fig. 2, is held by the type'bars 3 positionedin two adjacent grooves, while' the type 5 is held in place bypositioning the next type holding bar in the second groove, as shown, while the type 6 is held by placing the type holding bar 3 in the third groove so that the intervening grooves 2 are spanned by the type as shown at the right of Fig. 2. These type holding bars are provided with sloping or under-cut sides as shown andthe type 25; is slightly wider than the distance between :the upper edges of the adjacent type holdingbars so. that it is necessary to press the type into the space between the type holding bars and as the rubber ris under compression the type is firmly o held in place. It will also be vnoted that the rubber type expands beneath the under-cut edges of the type holding bars which prevents the type from being pushed over in the inking or print ing operations. may be also provided with longitudinal grooves 2a as shown in dotted lines in Fig.v2 which are of the same form as the grooves 2 but extend longitudinally of the type bed in case it is desired to reverse the type bed and set the type longitudi nally of the type bed. In this case, the spacing of the grooves would be the same as shown in full lines in Fig. 2.

The portionV Iinay be inserted in the groove 2, as shown in Fig. 5, and the ianges I I will engage in the grooves'S onV opposite sides of the@- `type bases. This form, shown in Fig. 5, maybe also reversed or inverted by inserting the flanges In this rubber'type I2 may beengaged therebetween. The type holdingv bar shown in Fig. 4 Vmay also be inverted in the'sarne manner for holding rubber type andY 'will then haversubstantially the -outer surface `contour of the type` holding bar above. thegroove 2. For holdinggsolid base type,V

such as wood block or solid metal bases, the sheet.

metalv type bars are positioned with the spring flanges extending upwardly so that the solid base K type maybe rmlyren-ffaged therebetween by providing grooves in which the spring flanges engage, while withthe compressible type, .such as rubber base type the type holding bars may be inverted and need'not be compressible. as the type itself may be compressed into Vthe space `between .the

bars.V

vThe simplest. form of type holding bar and groove is Vshown in Fig. 7 in which a `metal bar I5 is kprovided which is rectangular in cross section and fits .in a rectangular. groove I5" in the type bed l.V .This type holding bar win retain the type imposition and may be inserted in the top of the type bed rather than froin'the edge,'if desired,

I and while it may not hold the'type rasiiirmly as the other forms'of type holding bars, it `maybe usedwith good results under normal conditions.

AThe sheet metal form of type holdingbar as suggested in'l'igs. 4, 5', and 6 has a flexiblewall permittingthe type to be `introduced therebetween Vby pressing the side wall of one type bar in a direction away from the adjacent type holdingl bar permitting an insertion of the type there-y between. vEither the rubber forrn'or the solidV unyieldable form may be used. Such latter form is preferably Ygrooved to receive the edge of the sheet metal holding bars as more particularly shown in. Fig. 5. Rubber type may be used with this character of'type holding barand they may be shaped of greater width at the base than' between'the contactingV edgesof the type holding bars. Whenever occurring in the appendedV claims,V the term flexible type holding bars refers to a'forrn of bar such as shown in Figs.

4 to 6 in Ywhich a wall'or ange ofthe type. bar is Y capablejof being'fiexed toward its companion wall.

Frornthe foregoingdescription it becomes evident'that the device is very simple and'efiicient in. operation, will not easily get out of order, provides an easy and simple arrangement for mounting type-on a type bed and provides a device which accomplishes the .objects described.
