rRI'NTnRsQUorN Application filed November 21, 1927. Serial No. 234,727.

The invention relates to what is known in the printerstrade as a printers quoin for securing'a typeform rigidly in position in a 'printers chase preparatory to being used in a printing press." The invention consists of a printers quoin having a suitable body with a. clamping memberitherein which has an outward and downward movement which not only forces thev typertogether in ahorizon? tal plane,but also forces them downwardly against a hard smooth plate so the type will be laid evenly and ma symmetrical manner to prevent workup's.

The invention fur ther consists of special details of construction and will be taken up in detail in the specification and claims.

l a printers quoin having a clamping mem-- The object of the invention is to provide 7 berwith an outwardand downward movement to force the type together and force them downwardly, and atthe same time have vthe various moving parts in relation to each --other and to thezframe that they cannot'be A removed 'or'misplaced thereby making, a printers quoin a complete unit in construe tion, which is simple in construction strong and durable, cannot get out of adjustment and. cheap to manufacture.

-'Referring to-the figures, Fig. 1 is ap'la-n :view of a'printe rs ehase'with a printers type" form and furniture located in such rev lation to the chase that the' type form can be" 'securely fastened in position by the improved printersfquo'in,having one or many clamping members; :Figure 2 1s a front ele- Vation sh'owing the clamping member of the quoin; Figure 8is"a -rea r elevation of the r main bodyshowing the slot in the clamp quoin.- Figure 4 is a plan view'parts broken away and'others in section. Figure 5 is an end view. Figure fi is across-section ofthe support and the screw. in the slot for limiting the movement of the clamping member.

Figure 7 isa cross section through the body and the clamp showing the operating screw "and the inclined slot." ;Figure 8 is a cross section taken in the same place as Figure 7,

exceptthatthe clamping member is in its aw rd i o it s lgEis re 91$ a n r to be used to build detail showing a ledge to prevent the screw from being removed.

. .i Referring to the drawings, 10 represents the body support of aprinters quoin having a suitable clamping member which is used for clamping the type form 11 rigidly in position to the chase 12. r The varying sizes tion the furniture is set into position in such a way that when pressure is brought to bear against the chase in the furniture they will pass each other at right angles. This allows ,the pressure exerted to take place on all four sides, thereby clamping the form rigidly to the chase. r

Single or doublequoins can be used as desiredbut as the invention directly relates to the quoin itself the description of one would be sufficient.

The body of the quoin 10 is provided with an inclined longitudinal slot 14 adapted. to receive the adjustable sliding clamp, having a clamping member15 and'a supporting member 16..

The lower part of the body 10 1s cut away forming two supporting membersl7 and 18 which lessens the friction surface of the quoin body on the table in which the type form is set up and allows the movable parts to be assembled; The supporting member 16 of the clamp is formed at a suitable angle to the clamping member 15 which allows the said clamp 15 when it moves outwardly to also move downwardly. ,These resulting movements exert an outward and downward movement against the printing forms which would otherwise cause the form and the furniture to buckleif the clamp 16 moved outwardlyin a straight line. The

even manner by a continued upward and downward movement form 11 and" the furniture l3 is-clamped V rigidly in position in an of the clamp 15, so that they willnot only be pressed together, but will'be forced down- Wardly anddownwa'rdly for clamping spur v I -nerhaving-all the type in a registeringpo clined supporting member 16 is a SelIll -ClY-h cider and J conical inclined depression 19 which cooperates With the screw QO'for forcing theclemplng members 15 and lfiontposes. p 1 The screw 20 is provided itha ball end 21 which conforms to'the depression "19; The
