In order to incorporate. n. he pre s. al oi the eoodfeatu es h re nabove set fo h and eliminat s l f. the undes rabl feature al o. et rth. above e ch u in h s at n inner corner there: ofa basic alignment face 8 which extendsver-y tically and longitudinally of the press and. is carefully and accurately machined'because this face on each housing forms the basic plane to which all other surfaces hereinafter referred to, are relative. Suitably mounted upon ea h basic alignment face is a liner 9 primarily designed ofa predetermined thickness of bronze preferably to function as a replaceable wear plate. Each housing also carries an inward facing face I!!! which need not necessarilybe machined to a'great degree of accuracy other than it is important that this face ID present an accurate and true plane face extending vertically and transversely of the. press. This latter face Ill is substantially a. continuation of its related basic face and is disposed desir b y a nine de ree or a a. true ri ht angle thereto. The face I0; is further provided with a removably secured, vertically extending inwardly facing Wear plate H preier-ably formed of bronzefor purposes which are apparent.

Outstanding from the platen at a predeter mined portion spaced outwardly of the press from a related housing is a wall, barrier, lug or abutment 12 which may or may not be formed integrally with the platen. Each wall extends vertically and is substantially parallel with a related inwardly facing face 10. Intermediate each abutment and its associated end of the platen there is provided an outwardly exposed, vertically directed face l3 desirably formed or machined true so that it is perpendicular to an adjacent face ill on the housing and its related bronze wear plate. This outwardly exposed face is desirably coextensive with a related abutment but need not necessarily be made so. Positioned between each abutment and its related housing corner is a rear shoe or guiding gib l4 having 1 an inwardly exposed face it arranged to bear 13. Main holding bolts or anchor means [6 are spaced in vertical alignment along each guiding gibto hold the latter in a predetermined or fixed position. Assisting the anchor means are a series of aligned auxiliary holding bolts I! also functioning as a means by which the related guiding gib is retained in fixed position on the platen. The main holding bolts and auxiliary holding bolts extend through suitable apertures lBa. and Ha respectively in a related guiding gib and which are desirably made greater in diameter than that necessary for the accommodation' of the occupying bolts so that while the bolts remain fixed relative to the platen the guilding gib is thus arranged preferably to be shifted in one plane only toward or away from the next or adjacent housing or the adjacent abutment for the purpose to be hereinafter made apparent. Each rear shoe is provided with a vertically extending horizontally disposed, inwardly exposed surface l8 which is machined true and smooth and is desirably disposed in a plane parallel to and at a predetermined exact distance from a companion inwardly exposed face l5. This surface 18 is so arranged and disposed to bear against and be in sliding engagement with a correspondingly disposed surface or rubbing surface 9a on a related liner 9. In other words, the surface 18 is in sliding contact with the'liner 9 when the shoe face 15 and platen face 13 are in bearing relation with one another and thus aplurality of longitudinally spaced surfaces are arranged to assist in guiding the platen along a fixed vertical path and assist in preventing the platen from shifting, wabbling or moving transversely of the press from a true vertical path.

Forming in substance a continuation of the surface l8 of each rear shoe or guiding gib is a vertically extending, transversely disposed, out-' wardly exposed surface 19 which upon certain adjustment being made is arranged to slidingly engage a contiguous liner ii to assist in preventing a longitudinal shifting action of the platen. Extending through suitably drilled vertically aligned holes 20 in each abutment are a series of, pulling or drawing set screws 2| which extend into suitably tapped openings in a related guiding gib so that any manipulation of the drawing set screws will move the affected guiding gib toward the companion abutment. Each guiding gib or rear shoe is also provided with a'plurality of pushing set screws 22 with desirably a pair spaced about or in vertical alignment with eachdrawing set screw. The heads 23 of the intimately against a companion or coplanar face 4 pushing set screws are arranged in abutting relation with a companion abutment so that, the pulling set screws permitting, a proper manipulation of the pushing set screws will result in a related rear guiding gib being urged toward an associated housing.

A mechanic unskilled in the art of properly adjusting a press may easily adjust a rear side of a press embodying that portion of the invention hereinabove described by simply letting up on the main and'auxiliar holding bolts 16 and I1. This being done the pushing set screws or pulling set screws are then manipulated so that the distance between a butt of one rear guiding gib and its related barrier indicated by the character X is equal to the distance between a butt of the other rear guiding gib and its companion barrier indicated by the character W (see Figure 2). When these distances are equal and the surfaces iii are in sliding contact with their liners, the main and auxiliary holding bolts are tightened to lock the rear guiding gibsin their thus set locations. The pulling set screws are then properly tightened to relieve the holding bolts of any sheer stresses to which they might be subjected in service.

Referring now to what might properly be considered as the front of the press each front inner corner of each housing is provided with a diag+- Outstanding from the platen in a direction opposed to the direction of the abutments 12 but preferably in transverse alignment therewith are a pair of longitudinally spaced, vertically extend-- ing shoulders, partitions or abutments 2E. The shoulders may be made or formed integral with the platen or, if desired, may be made asseparate components and firmly secured to the platen. Interposed between each shoulder and its adjacent inclined surface is an outwardly exposed vertically extending face 2! which isdesirably machined or formed true and smooth and parallel with the face 13. Arranged in intimate contact with and surface bearing relation with each face 21 is a front shoe or guiding gib 28 held in a predetermined or fixed position on the platen by means of main tie bolts 29 arranged in. vertical alignment intermediate the transverse limitsof a related guiding gib. Spaced from the main tie bolts toward an associated shoulder is a. series of aligned auxiliary tie bolts 30 which assist in maintaining a gib in a fixed position against stresses to which it will be subjected in service.

The main and auxiliary tie bolts extend through.

suitable apertures 29a and 30a respectively which are of greater diameter than the related. tie

bolts so as to incorporate in the structure adegree of adjustability which will be brought out morev clearly hereinafter. Each front guiding gib is provided with an inclined somewhat inwardly exliner 25. Spaced at predetermined intervals and vertically along each shoulder is a series of draw ing screws 32 which extend freely through the related shoulder and are in threaded engagement screw 33 in threaded engagement with the front shoe and having-a-head fld bearing'against a related shoulder. With the rear guiding gibs-adjusted as previously set forth the tie bolts are loosenedand the screwsiz' and 33 are manipulated sothatthe distance between the butts ofthe front; guiding Ribs n Shoulders e a ,asind t vth h r t sri n -i Th n ra nee ia nl equalize the dimensions Y and"Z and observe that the front guiding gib inclined surfaces 3| are in intimate contact with the brushing liner surfaces 25a and further observing that the rear shoe surface 18 is in sliding contact with a related liner rubbing surface Be. It will be here noted that a proper manipulation of the

screws

32 and 33 will not only cause the platen to be centered properly between the housings longitudinally of the press but will also cause the platen to be centered properly transversely of the press. Having accomplished the above settings the main and auxiliary bolts are tightened and so far as the proper positioning of the platen is concerned the press is ready to be operated with assurance that the platen will move only along a true predetermined vertical axis.

From the above it will be noted that various changes and alterations may be made to the illustrated and described specie of the invention without departing from the spirit of the invention and scope of the appended claims.
