:PRINTER/S REDUCING-G'AGE,

To all whom it may concern:

Be it known that I, CLOYDE H. SMITH, a citizen of the United States, residing at San Jose, in the county of Santa Clara and State of California, haveinvented certain new and useful Improvements in Printers @Reducing-Gages, of which the following is a specification.

in performing the work, and in which the width 'and depth of the illustration will Itemain constant.

With the foregoing andother objects in view, which will appear as the description proceeds, the invention resides inthe combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings 1- Figure 1 representsa front elevation of a gage constructed in accordance with this invention,

Fig. 2 represents a transverse section taken on the line 2-2 of Fig. 1, and

Fig. `3 is a detail sectional'view through 4the frame and clip 11.`

In the embodiment illustrated, the device constituting this invention isshown inthe formof a rectangular frame 1 constructed' of any suitable material, preferably of fiat metal'strips and which maybe finished in any suitable or` desired manner; This frame has its top bar' 2 and one side bar thereof provided with in'dicia'at one. edgel v is designed to enter the recess 6 5o`f the bar'2l rated on' each bar by arecess l`6', one of whlchI Specification of Letters CPatent. Patented Feb, 10, 1920, Applicationled September 12, 1917. Serial No. 191,087. l i

extends longitudinally on the upper face of each of the bars 2 and 3. It is well known that substantially fourteen agate lines are longitudinally yieldable divider being employed. This divider is composed of wire 7 having a helical spring 10 connected with one end' thereof.

The other `end of this Y wire is connected with the upper left hand f corner of the frame 1 by means of an eye 8 attached to said corner and which is coni ,nected with a Dcoperating eye 9 carried by the wire. The end of this wire 7 Yconnected with spring 10 also has an eye 9 with which is connected one end of the helical spring 10, the other end of said spring carrying a spring clip 11 of any suitable construction,

which is adapted to be slid along the outer edge of the lower bar 12 of the frame nand also along the outer edge ofthe right hand side bar 13 so as to divide diagonally any rectangular figures constructed upon the frame by means now to be described. ,e

Two strips 14 and 15 are provided which are designed to intersect each other at right angles and to have their opposed ends hookedvover the opposed bars of frame 1 as is shown clearly in Fig. 1. These strips 14 and 15 are alike except that the markings are reversed, Ieach being provided along its side edgeswith indicia to indicate agate and pica lines as shown at 18 and 19, respectively, approximately fourteen vagate lines being used to an inch and about six picas. These indicia are separated by any suitable means, longitudinally extending llaterally spaced lines 20 being here shown.

The strip 14 hasl its opposite ends folded as shown in'Fig. `2 to'provide hooks as 16,` the memberL 14 being designed to lhookover the'outer edge" of the top bar 2 and the bot'-v tom bar 12 and to be `moved along said bars of which is shown in Figl 2 and which pin The `lever'17"which carriespin 17is` de pressed to 'release'thepin andsaid in snaps lnt engagemel'itk with the frame w 'en pressure von the'lever is relieved.. .By so constructing this connector for strip 14 1t wlll ybe obvious that the strip may loe operated toadjust it to the desired position with the least possible eXertion'on the part ofthe operator .and with a minimum consumption of time, it being understood that .speedy operation of thevdevice is of utmost importance. The strip 15 correspondingly hooks over the outer edges of theside bars 3 and 13 and issimilarly provided with a spring pressed pin 17, which operates in the same manner that the pin 17 does, for securing strip 15 in adjusted position. :It

willthus be seen that these two stripsmay be `moved on the bars with which they are engaged and positioned to intersect at right angles at any desired point, according to the size ofv the picture to be reduced or enlarged. The wire 7 must overlie the strips' 1,4'and 15 in order that said wire may be shifted in the manner above set forth.

In the operation of this device, when it is desired to reduce a drawing, say, of a size twelve inches long by six inches wide, to occupy a space not more than four inches long, it would be necessary to determine how wide proportionately in agate lines the reduced drawing should be. In order to determine this with this gage, the drawing `to be reduced should he placed beneath the gage so that its upper left hand corner lwould line up exactly with the upper left hand corner of the gage at a point where wire 7 is fastened to thei'gage. Then this wire 7 is laid across the drawing, passing directly from the upper left hand corner of the drawing to the lower right hand cor-` ner thereof, thereby dividing the drawing into two equal parts or angles. When this has been done, the strip 14 of the gage is moved over until the four inch point on the scale of the gage is reached. Then the strip 15 of vthe gage is moved until it intersects the strip14`with wire 7 at the point of intersection. Then all that is necessary to ascertain how many agate lines long the drawing should be is to glance at the left hand scale of the gage, which will show the exactfnumber of lines which are necessary to be used and a glance to the top scale will disclose the width.

It. will thus be seen that the use of this device saves all mathematical calculations as pertaining to printin will be clear to those versed in matters apand that a drawing may be reduced in vsize foryuse as a cut,

with the sides `having the same proportions to each 5other as the sides of the drawing have to .each other. This is accomplished by measuring ofi" on the side bars 2 and 3 of frame 1 the lengths of two sides ofthe drawing to be reduced and then arranging the wire 7 so that it will extend across the pointof' intersection of' the bars 14 and 15.

`varying in size from that of a newspaper sheet to one of verysmall size.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while have described the principle of operation of the invention together .with the device which In this manner a rectangle is ob 1 now consider to be the best embodiment thereof, l5 desire to have it understood that the device shown is merely illustrative and that such changes may loe-made as are within the scope of the claimed invention.
