(Cl. i-394) f 13 Claims.

This invention relates to a make-up gauge for use in squaring, sizing and justifying typepage forms under lock-up pressure prior to assembling of the forms for transmission to the printing press.

More particularly, my invention is directed to novel means for independently and rapidly advancing and retracting two adjacent lpressure bars which are part of the adjustable form clamping frame embodied in the make-up gauge of my invention.

Reference is made to United States Patents Nos. 2,065,253 and 2,114,946 which disclose make-up gauges of the character to which my invention has been applied; As shown in said patents, the gauge .comprises a base plateior supporting a type-page forml a frame hingedly secured to the base plate, a pair of cross bars havingV separable intertting connection with the frame whereby they may be xedly positioned relatively to the frame acco-rding to the required size of the type-page form to be justiled, and a pair of retractible pressure bars mounted in the frame and adapted to cooperate withrthe said cross bars to produce form justification under lock-up pressure.

The means heretofore known for actuating the said retractible pressure bars in make-up gauges of the character described have not proven entirely lsatisfactory and efficient, and it is the object of my invention to provide means for actuating the pressure bars whereby said bars can be operated rapidly and independently of each other, and whereby said bars will exert uniform pressure throughout their lengths on the form against which they bear, and whereby said bars will remain square and parallel to opposite bars even when meeting unequal resistance from certain lines of a type form which may be longer than others.

Another object is to provide pressure bar actuating means including a longitudinally movable member adjacent the pressure bar which when moved a very short distance in the direction of its longitudinal dimension will impart to the pressure bar a relatively long movement transversely oi the pressure bar. A Y Y The pressure bar actuating means hereinafter more fully described comprises an actuating bar parallel with the pressure bar, provided with a series of dou le angle, short wedgel surfaces adapted to coact with a series of double angle, short wedge surfaces on the rproximate edge of the pressure bar. The double `angles of the coacting wedge surfaces and their disposition on or to the frame members;

Y in the following specication.

Fig. 5 is a plan view of one end of the pressure bar, detached.

Figs. 6 and 7 are transverse vertical sectional views taken in the planes ofthe lines E-B and 1-1 of Figs. 4 and 5, respectively.

Figs. 8 and 9 are transverse vertical sectional views taken in the planes of the lines 8--8Y and 9-9 of Fig. 3, respectively.

In that embodiment of my invention shown in the drawings,the make-up gauge' comprises a base plate I, which supports the type-page form (not shown), the plate I0 being provided with lugs II, I I, through which extend pins I2, I2,V whereby aV rigid frame I3 is hingedly mounted on the plate I0. The frame VI3( isI rectangular and its four side members have top plates I4, I5, I6 and I'I which denne a rectangular opening in the frame. The inner edges of the four frame members are toothed as indicated at I8, and adjacent the teeth said frame members carry numerical scales indicating pica measurements.

A pair of abutment or cross bars I9, 20 are interleaved so as to be movable relatively to each other, at right'angles to each other, and they have toothed ends 2l and 22, respectively, adapted to engage the teeth I8 on the frame members I5-I'I and I4-I6, respectively. TheY positions of the Aabutment bars may be adjusted with the aid of the numerical scales on the frame members, to provide a rectangular space of the desired size to receive a type-page form. When the cross bars |9 and 29 have been positioned in teeth-meshing relation in the frame, they will be held stationary until removed.

Mounted in the frame opposite the abutment bar |9 is a pressure bar 23 and opposite the abutment bar 29 is a pressure bar 24. Said

pressure bars

23 and 24 lie under the frame plates I6 and l1, respectively, and on the horizontal portion 25 of an L-shaped bottom frame plate 26 secured to the top frame plates by screws 21 as best shown in Figs. 3 and 8.

Between the vertical or thicker outer portion of the L-shaped bottom plate 25 and the

pressure bars

23 and 24 are actuating

bars

23 and 29, respectively, which, like the pressure bars, are located between the frame top plates and the horizontal or thin portion 25 of the L-shapedbottom plate 23. The actuating bar 28 is parallel with the pressure bar 23 and the actuating bar 29 is parallel with the pressure bar 24. The construction and operation of the two sets of actuating and pressure bars are identical and therefore the following description of the coacting

bars

24 and 29 will be applicable also to the

barsI

23 and 28. Y

The pressure bar 24 has a straight edge 35, cut away at one end at 3| to accommodate the pressure bar 23 when said bars are in advanced po- 1 sitions. Inwardly of the edge 33, the thickness of the portion 32 of the pressure bar 24 is decreased, the thinner portion 32 lying in the plane of the lower portion of the thicker part of the pressure bar. The edge 33 of the thicker portion of the pressure bar 24 is perpendicular to said part 32 and is located about midway between the

longitudinal edges

33 and 34 of the pressure bar. Said edge 33 is provided with a series of double angle short wedge members 35, the wedge surface 36 being disposed at an angle of approximately and the wedge surface 31 being disposed at an angle of approximately 14, the latter being connected to the edge 33 by a right angle surface 38. The thinner part 32 of the pressure bar is provided witha slot 39 near each end for a purpose tobe explained. y

As exemplied by the

bars

28 and 29, Veach actuating bar has a toothed end 4i), a straight edge 4|, and a series of wedge members 42 opposite the edge 4|. The wedge members 42 have wedge surfaces 43 disposed at an angle of approximately 45 and Wedge surfaces 44 disposed at an angle of approximately 14 relatively to the edge 45.

The wedge surface 44 merges with an edge portion 4B substantially parallel with the edge 45, said portion 4S being connected to the edge 45 by a right angle surface 41.

Each actuating bar has a longitudinally extending groove 48 in its upper surface adapted to receive a guide tongue 49 secured by pins 49 to the frame top plate I6 or i1, as best shown in Fig. 8, to guide the actuating bar in moving 1ongitudinally adjacent the member 2S. The bottom of the wedge shaped portion of the actuating bar is cut away as indicated at ^5|? (Figs. 6 and 8) to allow the wedge members 42 of the actuating bar to rest and slide on the thin portion 32 of the pressure bar 24.

The actuating and pressure bars are loosely connected together by pins 5| fixed in the bottom of the actuating bar and extending into the slot 39 in the thin portion of the pressure bar when theyare assembled as shown in Figs. l, 2, 3 and 8.

The actuating

bars

28 and 29 are actuated by means of

pinions

52 and 53, respectively, which engage the toothed ends 43 of said actuating bars. A pinion 54 in mesh with the pinion 52 is shown in the present embodiment. The purpose of these pinions is to impart their intended movements to the actuating bars by rotating the pinions 54 and 53 in opposite directions, so that the power being applied to said pinions will be counterbalanced, and shifting of the device as a whole on its support will be avoided.

The pinions 54 and 53 are rotated by the operator by means of a wrench called a quoin key in the printing industry, whereby the actuating

bars

28 and 29 are moved in the direction of their longitudinal dimensions, and the pressure bars 23 Fand 24 are moved transversely. The

wide angles

35 and 43 of the coacting pressure and actuating bars produce rapid movement of the pressure bars. The

low angles

31 and 44 of said coacting pressure and actuating bars produce the lock-up movement. The working range of these

wedge surfaces

31 and 44 is equal to the altitude of the low angles,-in the case shown, about 332-. Thus forms which are oversize more than g3g cannot be locked up.

rIhe pressure bars are retracted by rotating the pinions in directions opposite those used in advancing the pressure bars. As the actuating bars move from the positions shown in l to those of Fig. 2, the pinsI 5| on the actuating bars, engaged in the slots 39 in the pressure bars, retract said pressure bars as shown.

While the type-page form is being placed on the base plate I0, the pressure barsl are retracted as shown in Fig. 2, and the working space is defined by the abutment bars I9 and 20 and the frame members I3 and |1 under which the pressure bars 23 and 24 lie when retracted. In this position there is provided a rectangular space 1/2 to iiwider and longer than the type-page form t0 be justied. When the operator is ready to lock up the form, the pinions 52-54 and 53 are rotated and the actuating bars 28 and 23 are thereby actuated. The wedge surfaces 43 of the actuating barsl then engage the wedge surfaces 36 of the pressure bars and rapidly move the pressure bars into advanced position, about 1/2" beyond the frame members I6 and |1, and then the wedge surfaces 44 and 31 come into coacting relation to effect lock-up of the form.A The wedge surfaces 44 and 31 may move into fully contacting positions as shown in Figs. 1 and 3, or into positions where they are only partially in contact or overlapping relation depending on the form to be locked. l

To facilitate lifting of the frame relatively to the base plate I3, I provide a lever 55 at the side opposite the hinge pins I2, |2. The frame may be propped up by the props 56, 5S.

After the form has been justified and locked, the type page may be tied and after the pressure bar s have been retracted, the tied type-page form may be transmitted to a printing press, as is well understood in the art.

Changes may be made in details of construction without departing fromthe scope of my invention. Y Y
