LOCK-UP Fon PRINTERS foams.

SPECIFICATION forming part of Letters Patent No. 380,597, dated April 3, 1888.

Application lcd November l, 1G87. Serial No. 253,952. (No model.)

To alZ whom, it may concern:

Be it known that I, JACOB Bonson, of Milwaukee, in the county of Milwaukee, and in the State of Visconsin, have invented certain new and useful Improvements in Lock-Ups for Printers Forms 5 and I do hereby declare that the following is afnll, clear, and exact description thereof.

My invention relates to devices for locking up forms in type-beds or chases; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure l represents a plan View of my invention partly broken away and in operative position; Figs. 2, 3, and 4, sections, respectively, taken on lines 22, 33, and 4 et of Fig. 1. Fig. 5 is an elevation of a key employed in connection with my device.

. Referring by letter to the drawings, A represents a printers chase, and B a form of type contained in said chase. Between one side of the form and the chase is arranged my locking device, the latter consisting of two parallel bars, C D, flanged upon their inner sides and united by peculiar toggle-joints, that will be hereinafter described.

Pivot-ally connected to the dange c of the bar G, on each side thereof eqnidistant from its center, are the inner ends of plates E E F F, oppositely arranged in pairs, each pair constituting one section of a toggle-joint.

Pivoted between the plates E E and F F, at their outer ends, are the rightangular ears g on the adjacent ends of bifurcated arms G, and the outer ends of these arms are in turn pivoted to the flange d of the bar D, each of said arms constituting another section of a toggle- The plates E E are provided with circular openings, in which fit the flanges h of an eccentric disk, H, the latter being loosely tted in the head of a rack, I, and provided with a seat or opening, j, to receive a suitable key. The plates F F are also provided with circular openings, and in these openings is litted a round hollow casting, K, through which passes the free end of the rack I. Integral with the casting K are arms M N, respectively arranged adjacent to the edges of the rack, the arm M being provided with teeth m to engage said rack, and the arm N has a lateral liange, n, that serves as a grip for the operator when it is desired to actuate said casting to ed'cct an engagement of said teeth.

Vhen a form B is placed in a type-bed or chase, my device is placed so that whenspread apart the arm G thereof will bear against a side-stick, b, of the form and the arm D against one'side of the bed or chase. The operator now takes hold of the grip n on the arm N, and by a slight movement of the same in an ontward direction causes a partial revolution of the casting K to bring the teeth m. on the arm M into engagement with the rack I, and thereby form a lock. A key, J, is now insertedin the seat or opening j in the disk H, and by a slight turn of this key in either direction the rack I is actuated to canse a further spreading of the toggle-joints, whereby the bars G D are firmly bound against the chase or bed and typei'orm, and the latter thus locked up ready for the operation of a press.

One or more of my locking-np devices may be employed, according to thesize of the chase and that of the form, and when aform islocked up in a chase and the latteris smaller than the type-bed of the press on which it is desired to work said form one or more of my devices can be employed to secure said chase and its contents on the type-bed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A device for locking up forms in typebeds or chases,that comprises two parallel bars, toggle-joints uniting the bars, a rack eccentrically connected to one of the joints, a cast ing pivoted to another of the joints and pro-'- vided with a passage for the rack, an arm on the casting for engagement with the rack, and suitable means for actuating this rack when engaged by the arm, substantially as set forth.

2. A device for locking up forms in typebeds or chases, that comprises two parallel bars, toggle-joints uniting the bars, a rack eccentrically connected to one of the joints, a hollow casting pivoted to another of the joints and provided with two arms, one of which constitutes a dog to engage the rack and the other a lever for actuating the casting to cause said engagement, and suitable means for operating IOO ing K, having the arms M N, substantially as. set forth. I

In testimony that I claim the forego1ng I have hereunto set my hand, at Milwaukee, 1n I5 the county of Milwaukee and State of Wisc0n sin, in the presence of two witnesses.

3. A device for locking up formsin typebeds or chases, that comprises the parallel bars C D, plates E E F F, pivoted in pairs to the bar C and provided with circular openings,- bfurcated arms G, pivoted to the bar D and having ears g, pvoted in turn to the platesE E F F, the eccentric disk H, provided with an opening, j, and flanges h, the rack I, havingits head 'L' loosely fitted on the disk, and the cast- Wi tn esses:
