timeon a large sheet which, after the printing is folded to form a folio. It is important that all of the headings shall be lined up accurately, that is, there shall be the same distance from the bottom of the sheet to the top line of each printed page of the folio so that when the printed sheet is folded the top of the printed pages of the folios will be eX- actly in line and have the same head margin, that is the top printed lines of the pages will all be in the same horizontal line and at the same distance from the top.

It is also important where a line runs across two pages to form a double page that there shall be perfect alinement of the lines in the two pages.

In making up the form the type setter usually first sets itas nearly correct'as he can while working rapidly and guiding only by his eye leaving it to be trued or lined up afterwards by a line-up device of some sort as there are usually more or less slight inaccuracies in the first setting up.

The object of the present invention. is to provide a line-up gauge whereby the forms may be quickly and accurately lined up and whereby any inaccuracy in the preliminary setting up may be corrected. 7

The invention will be fully understood from the following description when taken in connectionwith the accompanying drawings,and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings:

Fig. 1 is a plan view of a tool embodying the invention.

Fig. 2 is a side elevation of the device shown in Fig. 1.

Fig. 3 is a section on line 3-3 of Fig. 2.

Fig. 4 is a section on line 44 of Fig. 3.

Fig. 5 is a plan view of a form as first made up and showing the gauge in position for the lining up.

Fig. 6 is a plan view showing the form after it has been lined up the use of the gauge.

Fig. 7 is a plan View showing the gauge in inverted position in the form as used in lining'up a double page.

The line-up gauge will be first described by itself and then its application to use in lining up the form will be described.

The device is substantially a T-square with an adjustable split leg, that is, theleg of the T comprises two parall l straight-edge members adjustably connected with the head bar of theT and movabletoward and from each other so that they may be adjusted to vary the distance apart from each other as well as to vary the distances from the ends of the head bar and having means for clamping them in theiradjusted positions. Their outer edges are straight and parallel with each other and perpendicular to the straight-edge of the head bar.

Referring to the drawings the head of the gauge comprises a straight-edge bar 10 hav ing in its upper face a dove-tail groove 11.

The legs of the gauge consist of two parallel members 12, 12" having their outer side edges straight and parallel with each other. Their upper ends have respectively arms 13, 13 extending at right angles to the leg portions 12, 12, said members 13, 13 extending in opposite directions to each other and having respectively tongues 14, 14 which are. slidable 18, 13. are provided respectively with clamp ing screws 15, 15 for clamping them in their adjusted position on the head bar to hold the legs 12, 12 also in their adjusted position.

The gauge thus far described is all that is necessary for using the device for a head gauge and a side gauge will be hereinafter described except where used in lining up doublepages. I V

For use inlining up for a double page there are provided additional attachments. Near the ends of the bar 10 there are provided pins in the groove 11 of the head bar 10. The'arms up for a double page. Preferably the pins 16 are headed screw pins which can be ad justed to vary the elevation of the gauge above the bottom of the gutter when the device is inverted as above described for use with a double page. The leg members 12, 12' are also provided with screw pins 17, 17 so that the pins 16 and 17 serve together as legs to support the gauge in its mverted position. 7

Each leg member 12, 12 has adjustable straight-edge members 18, preferably two on each leg member and sliclable thereon, said members 18 each having a straight side edge adapted to engage with one of side walls of i the gutter of the form as will be hereinafter described. Each of said members 18 has a slot 19 to permit it to be slidably mounted on the legs 12, 12. I

Referring to Figs. 5, 6 and 7 there is shown the manner-in which the device is used in lining up the form.

At 20 is shown the chase which with the enclosed type comprises a form, said form having the central horizontal gutter 21 within which the type setter places the spacer blocks 27 which space the type for the upper series of pages from the type for the lower series of pages. Thereare also gutters 22, 23, 24 which extend at right angles to the gutter 21 and space the pages laterally. For convenience these gutters 22, 23, 24 will be referred to as vertical gutters and the gutter 21 as the horizontal gutter.

There is shown the usual furniture or wooden blocks 25 and quoins 26 for support- 7 ing the type and holding it firmly in place in the chase. At 28 are shown the lines of type.

The form is usually first made up with the lines of'type in as nearly the correct position for the spacing and line up as the type setter can judgebv his eye without the use of the gauge.

After the form is thus made up in the approximately correct line-up the gauge should be applied by setting the head bar portion 10 in the horizontal gutter 21 and by setting the leg members 12, 12 in the upper part of the vertical main gutter 23 as shown in Fig. 5. By loosening the thumb screws 15 he can then adjust the members 12, 12' with relation to each other so that their outer straight edges will engage the-inner ends of the type which form the pages a, b at the two sides of the gutter. The set screws 15, 15 are then screwed down to hold the leg members 12,

r12'in proper spaced relation .so that their outer straight edgesare in contact with the opposite sides of said gutter.

inner ends of the type of the'pages on the two The bottom lines of the two adjacent pages will be in line with the straight edge bar 10 so that the side edge and the bottom edge of the pages a, b will be at right angles to each other. These two pages will be in correct position without further adjustment. It may be however that one or both of the two outer pages 0, (Z will be so set that there is a space 29 between their lower edges and the upper edge of the bar 10 so that those two pages are out of alinement with the pages a, b. In such case the type setter will take a lead or slug 30 of the right thickness and which for convenience may be in the page below in the same column of the form as shown in Fig. 5, and he will insert the lead in the pages 0 and (Z so as to bring all of the pages a, b, 0, (Z in the same line.

In order to line up. the headings 32 of a double page the type setter will then lift out the gauge and turn it face down with the leg members 12, 12 extending toward the lower edge of the form as shown in Fig. 7 instead of extending toward the top of the. form as shown in Fig. 6,

'He will then adjust the leg members 12, 12 into a position relative to the side edges of the gutter 23 wherein the outer edges of the slidable members 18 will contact with the sides of the gutter formed by the inner ends of the type as shown in Fig. 7.

He will then move the gauge into a position so that the straight edge of the head bar 10 can be used as a guide to line up the top linesof type if previously out of alinement.

What I claim is:

1. Aline-up gauge for proving type forms, having the general shape of a T-square having a straight-edge head bar and two straight-edge members parallel with each other and extending at right angles to the head bar, each of said parallel members having an adjustable connection with the head bar whereby they are adjustable longitudinally of the head bar and laterally with re lation to each other, and means for clamping the said parallel members in their adjusted positions, said head bar and parallel members having legs to support the gauge in the gutter of a type form, straight-edge members mounted on each of said parallel members and adjustable longitudinally thereof, said movable straight-edge members being adapted to serve as spacers to engage the sides of the gutter.

' 2. A line-up gauge for proving type forms, consisting of a straight-edge head bar and two L-shaped members adjustably connected therewith, one arm of each of said L-shaped members having atongue and groove connection with said head bar whereby the other arms of said L-shaped members are maintained parallel with each other and at right angles to said'head bar, the said arms of the L-shaped members which have the tongue and groove connection with the head bar being individually adjustable longitudinally of the head bar and with relation to each other, said head member and said parallel arms of the k right-angled members having adjustable members which serve as legs to support the gauge in the gutters, each of said parallel arms of the right-angled members having additional straight-edge members slidably mounted thereon and adapted to engage with the side walls of the gutter.

In testimony whereof I afiix my signature.
