The rear edges of the bed f are formed with lateral flanges f1l which will abut against the outer frame when the bed is inserted into the same, `so that the bed is kept in operative position during the printing operationV and an exact adjusting of the type form a is made possible.

The frame also carries such .parts of'the machne which in this specification are not chine in such a manner that it can be adjusted relatively to the type form bed, in that the spindle, on the sideA of the machine opposing the operators side, is connected to a pivot k2, which for instance may be located in a bore-in one of the standards In the constructional form of the invention shown in the drawings the upper end of the spindle is connected in such a manner to a head piece k1, that it can be rotated but not axially'displaced within-the same. `This head piece or Y sleeve 701 is directly connectedto the pivot 7a2.

The upper end of the `spindle 7c carries a bevel gear 7c3 the operation of which willfbe described in thefollowing specification." The spindle further carries a guide sleeve Z which is internally threaded and which is pivotally connected to therupper end of the type form bed, in that the said bed is equipped with a bracket or Varm m and a laterally projecting pivot on the sleeve Z is taken up by a bearing-shaped part m1 ofthis bracket. According to another constructional form of the inventionna pivot on the bracket m projects into a bore in the threaded sleeve Z. A threaded plate m2 keeps the pivot in position in the bearing m1, It will thus be understood that thev sleeve Z is pivotally connected tothe type form bed and forms a threaded guide in which the spindle 7c is rotating during the upward and downward movementsfof theV type form bed f. An inspection of the drawings especially of Fig. l will make it clear thatwhen the spindle 7c is rotated the sleeve Z will ascend or descend on the same in accordance with the directioniin which the rspindle is rotated. Hereby the part of the spindle 7c between the sleeve Z andl the .head piece'lc1 willV be lengthened or shortened and the inclination of the spindle will change according as the pivotof the sleeve Zis turned itsbearing m1. When the spindle 7c is rotated the sleeve Z and the type form bed will lthereupon be swung upward or downward about the shaft g.

n the ccnstructional form of the invention shown in the accompanying drawings the threaded spindle Il: is operated by means of a gear mechanism. The lengthened pivot k2 carries a gear p1 which is rigidly connected to a bevel gear p2, which meshes with the bevel gear on the spindle c. The gear p1 meshes with a spur gear p3 which is fastened to the shaft jv. VrThis shaft is supported by the machine standards ZJ and carries at its free end a hand wheelo or a suitable lever.

When the hand wheel 0 and the shaft p are rotated the rotation is by means ofthe spur gear p1 and p3 transmitted tothe bevel gear p2 and to the bevel gear 7c3 which again transmits the rotation to the spindle 7c,

whereby the sleeve vZ is moved upward or downward on the spindle c and the type form bed is moved into orout of operative position. A

`The bed plate may forrvinstance be locked in operative position at bothv sidesby means of wedge bars 1' (Figs. 7, 8, 9), which can be shifted in vertical direction in the sides of the frame c `and which are formed with alternating projections r1 and gaps or slots r2. `In one position of the said wedge bar thebed 7 will be released `and in another position it will be locked. The wedge bars r are arranged insuch a manner in parallel guide slots c1 in the frame members c onboth sides of the type form bar, that they can be displaced or shifted in. vertical direction. The conical projections r1 project into the bed f,fwhichis formed with corresponding' conical guides and with open intermediate spaces through which the projections r1 are moved (Figs. l, 8, 9, 10). The wedge bars r1 are conlcally widened in upward direction and Vcooperate in such a manner with correspondingly formed conical projections f2 on the type form bed, that the said bed is locked to its frame when the wedge barsr are forced downward. The side of the wedge bars facing the type form bed comprises projections and slots, which are located in such a manner relatively to the corresponding projections f2 in the-bed f, that the projections in the wedge bars will face the intermediate spaces between the projections f2 in' the bed f when the wedge barsare forced upward, i. e. out of locking position, so that the type form bed will be released and can be swung downward.

When the type form bed has been brought into operative position by means of the hand wheel 0 and the spindle 7c the wedge bars are lowered by means Aof a driving mechanism, whereby the conical projections of the bars will slide along the conical projections 'f2 (Fig. 8) and the type form bed will be drawn4 into the frame until the flange f1 abuts against'f vpartly cover the wedge bars 1;

The type form a is fastenedV in a mannerv known per se by means of a closing frame'j asa-Liese the member c. The raising and lowering of the wedge bars is effected by means of a hand wheel g1, which is fixed to the hollow shaft Q, surrounding the shaft p (Fig. 2). On the hollow shaft g toothedsegmentsor wheels g2 are arranged, which cooperate with racklike upwardly directed parts ofthe-wedgev bars 7'. When the gears g2 are rotated .by means of the hand wheel g1 and the shaft` g the wedge bars will be lowered or Yraised whereby the type form bed will be lockedV or released. j

In order to prevent thewedge bars from dropping out oftheir guides c1, retaining plates r3 (Figs. 8, 1l) are provided 8 the upper and'loweredg'es Vof which are inclined in known manner. The loweredge of Y the closing frame rests 1n a Vhet or ledge 15 which is fixed to the bed f by meansy of screws or the like and the upper edge is held in posii tion by means of clasps u, which pressthe type form against thelist z?. The clasps u are arranged on a common shaft u1, which is located in the type form bed and carries'a wormgear u2, which intermeshes with a worm a3.

This worm ua, is arranged perpendicularly to the axis of the shaft u1. The said worm ua can be rotated in the type bar bed'7 but canl not be axially displaced. The adjustment ofv the worm is effected by means of a key or the like (Figs. 5 and 6). v

It will be evident that the'type form can Ybe easily and securely fastened to the type form bed simply by rotating the worm a3 and the shaft u1 in such direction, that clasps 'u A are pressed against the frames. When the said parts are rotated in the opposite direction the type form is again released. l

The type form bed is preferably also,

made adjustable relatively to the vprinting cylinders in such a manner that the type form can be moved nearer to the printing cylinders when the surface atthel type form is worn 01T. This can be elfected by known means, for in stance by arranging the ends of the shaft in blocks which are displaceably arranged in the members c.
