T a/ZZ wtom it may concer-71,:

Be it known that I, WILLIAM J. Busse, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois have invented certain new and useful Improvements in Printers Quoins, of which the following is a specification.

This invention relates to that type of printers quoins in which the duplicate expandio ing-wedges are inclosed by a laterally-expansible casing or housingconnected together i against independent longitudinal movement, the objects of the present improvement being, first, to provide in the above type of printers quoins a disconnected or independently acting duplicate Wedge formation adapted to move in opposite directions and with which theinclination or slant of the wedge faces can vbe made very slight and yet zo accomplish the usual amount of lateral eX- pansion of the quoin, in consequence whereof, the tendency of the parts to jarring loose in l use is reduced to a minimum and the holding qualities of the quoin correspondingly in z5 creased; second, to provide an improved construction of the laterally-expanding housing or casing of the quoin, whereby the parts are connected together in a laterally-expansible manner only and at the same time afford means whereby the simultaneous movement of the duplicate wedge members can be positively insured. I attain such objects by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure l is a plan view of a printers quoin embodying my presentimprovements; Fig. 2, a horizontal section of the same, illustrating the duplicate Wedge formation; Fig. 3, a side elevation, andFig. t a transverse section.

Similar letters and figures of reference indicate like parts in the several views. i

Referring to the drawings, A A represent l the outer laterally-moving counterpart side pieces or wedges, the inner of faces which are inclined in opposite directions, as shown, so as to form inclined bearing-surfaces for the duplicate Wedges C and C', the inclined faces of which are arranged in opposite directions, 5o so as to correspond withthe inclined faces of the outer pieces A A, as shown, the contactfacesof the wedges being in a plane parallel with that of the outer bearing-faces of the side .pieces l and 2 of t'he quoin. As so constructed a duplicate Wedge construction is pro- 5 5 vided that acts in an independent or disconnected mannerl and in opposite directions, so that each individual wedge mechanism accomplishes one-half of the total expansion of the quoin, and in consequence thereof can be 6o` made with a correspondingly slighter inclination than would be the casein the usual single coactin g wedge mechanismnvhere the whole of the quoin-expansion is accomplished bya pair of contiguous inclined wedge faces. With a `6,5 decrease in the inclination of the wedge snrfaces, as above stated, a corresponding increase in the holding properties of the parts ensues, with a relative decrease in the liability of the parts jarring loose in practical use.

The housing or side pieces AA are connected together against independent longitudinal movement, but capable of a limited lateral expanding movement, by the following improved construction: The side pieces A A are made somewhat deeper than the wedges O and C and are formed with top and bottom flanges that are cut away to form interlocking hook-shaped prongs ct and 01,', that engage together, as shown in Fig. l, to admit 8o of the before-mentioned limited lateral eX- panding movement of the parts in the practical use of the quoin. Another practical advantage 'resulting from the above improved construction is that it affords a simple, ready, 8 5 and perfect means to form a fulcrum for the usual pinion-key or wrench in imparting a simultaneous movement to the wedge-pieces C and C in an endwise direction past eachV other, this being readily provided by an ap- 9o crture or orifice formed in the central part of the upper flange of one of the side pieces, as illustrated in Fig. l.

The duplicate wedges C and O are each connected to its .respective side or housing piece A or A by a guide stud c, passing through a longitudinally-extending slot a2 in the inclined or obliquely-arranged Web CL3 of the housing-pieces and provided with a confining head or washer c', as indicated in Figs. 10o 2, 3, and 4.

In the practical use the wedges O and C may be adjusted by blows, &c., upon their thicker. end. It is preferable, however, to employ the usual Well-known rack-and-pinion movement for effecting an adjustment. For this purpose the meeting faces of the wedges C and C will be recessed out at their top side to form thetoothed racks c2, in which the usual pinion-key will be inserted and by its :rotation impart the required longitudinal movement simultaneously and in opposite directions to said wedges and a corresponding lateral adjustment to the said pieces A, the central flange aperture before described constituting a fulcrum for the pinion-key in effecting the simultaneous movement of the Wedges.

The advantages resulting from my iniproved construction, in addition to those en- Asuing from the slight taper or inclination of the wedge faces, as before stated, are that vthe parts are all connected together and will not accidentally fall apart. An accidental blow upon the projecting'ends of the Wedge-v pieees will only tend to tighten the adjustment of the quoin parts instead of tending to loosen the same, as in some former constructions. It admits of a longitudinal movement of the wedges bodily together in an oblique direction between the housing-pieces without affecting the lateral adjustment of the same, this feature being of especial value in cases where the quoin is used close up to the corner of the type-holding chase.

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

` l. A printers quoin comprising, in co1nbination, an inner expanding wedge mechanism and an outer two-part housing formed withtop and bottom lian ges that are cutaway the top of the wedges and provided with an aperture to form a fulcrum for the pinion-key employed to impart simultaneous movement to the wedges, substantially as set forth.

3. A printers quoin comprising, in combination, a pair .of outer laterally-adjustable side or housing pieces, the inner faces of which are inclined in opposite directions, and a pair of duplicate inner Wedges, the outer faces of which are correspondingly inclined, the parts constituting a quoin having a pair of independent and disconnected wedge constructions, substantially as herein described.

4. A printers quoin comprising a pair of outer laterally-adj ustable side or housing pieces having top and bottom interlocking prongs a and ct and longitudinally-slotted Webs as, in combination with the duplicate inner wedge-pieces having guide-studs c, that pass through the slotted webs CL3 and are provided with confining heads or Washers c 1 substantially as set forth.

In testimony whereof witness my hand this 23d day of September, 1889.
