COMPOSING-BQOMGAW MITERL'NCT ARRANGEIYIENT.

Application filed March 6, 1922.

To all whom it may concern.

Be it known that I, Fan-wane Crrnsriinn, a citizen of the United States, residing at Berlin Township, in the county of W aukesha and State of \Visconsin, have invented certain new and useful Improvements in Composing-RoonrSaw Mitering Arrangements, ofwhich the following is a specification.

This invention relates to a composing room saw mitering arrangement.

It is found that borders cast in. type casting machines at times vary in thickness from 1/1000 to 5/1000 of an inch from the standard. Accordingly, standard gauges do not always give a setting for accurately initering.

One object of my invention is to provide simple and reliable means for making an accurate setting for borders and the like so that same may be accurately mitered.

Another object is to provide a simple and efficient composing room saw mitering arrangement which may be quickly 1nanipulated and which is adapted to meet the various requirements for successful commercial use.

These and other objects are accomplished by means of the arrangements disclosed by the accompanying sheets of drawings, in which Figure 1 is a top plan view of a composing room saw in combination with my improved means for accurately setting borders and the like to be mitered;

Figure 2 is a fragmentary front elevation of the same;

Figure 12 is a detail sectional view taken, in the plane of line 1212 of Figure 1; and

Figure 18 is a sectional view taken in the plane of line 13-13 of Figure 12.

The various novel features of my invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims.

The invention is illustrated in connection with a composing room saw, including a table 20 mounted upon a pedestal 21, there, being a saw associated with the table in a manner such that material carried by the table and properly positioned may be cut by the saw. The saw may be driven from any suitable source through a belt .3 which passes around a pulley 2i mounted on a shaft which carries the saw Material to be cut is pressed into engagement directly or indirectly with a front retaining gauge 20, the upper surface of which is provided with a graduated scale in order to accurately gauge the length of the linotype slugs or other material to be cut. (lo-acting with the front retaining gauge is a side gauge including an arm 27. It will be understood that the front retaining gauge 26 also forms a relatively fixed jaw which cooperates with a r latively movable jaw 28 between which material to be cut is clamped.

As mentioned hereinabove, the borders which are cast in type casting machines at times vary in thickness from 1/1000 to 5/1000of an inch from standard, and, as a result thereof, standard gauges do not always give a setting for accurately mitering the borders and the like. In order to overcome this disadvantageous feature, and to positively insure an accurate setting of the material to be mitered, I have provided simple, efiicient and reliable. means for accurately setting in a minimum amount of time material to be mitered. This setting means includes two cooperating members 29 and 30, probably best shown in Figures 5 and 6 in which the parts are on an enlarged scale. The member 29 has a front face 31 which cooperates with the front retaining gauge 26 in the application shown in Figures 1, 2 and 7 to 10 inclusive. It also has a side face 32 which cooperates with one end of a group of borders or slugs 33 used in determining a proper zero pointor setting. The member 29 also has what I choose to term interior faces, 34: and 35 which are arranged at right angles with respect toeach other and which respectively cooperate with interior faces 36 and 37 respectively, of the member 30. A set screw 38 is threaded into the member 29 and extends through an elongated slot 39 in one side of the triangular shaped member 39, there being a coiled spring 40 surrounding one end of the set screw 38 and being retained thereon whereby the spring 40 tends to yieldably hold the members 29 and 30 in their zero position as shown in Figure 5. It is apparent, how ever, that the members 29 and 30 may be given a sliding movement with respect to each other to accommodate a slug or border member 41, as shown in Figures 1 and 2 for the purpose of giving the proper setting to borders and the like to be mitered. The use of the miter gauge members 29 and 30 can best be illustrated by referring to Figures 7 to 10 inclusive. The miter gauge members 29 and 39 are first set in the corner against the front and side gauge members 26'and 27 respectively, whereupon a plurality of scrap slugs are clamped between the front gauge member or stationary jaw 26 and the movable jaw 28 with associated ends of the slugs 42 abutting and pressed up against the straight surface 32 of gauge member 29, whereupon all of the gauge and clamping members are moved longitudinally of the table 20 for cutting the opposite edges of the scrap slugs 42. This is done for determining the zero position as indicated in Figure 8. Let it be assumed that a plurality of border members of a given thickness are to be mitered. Under such circumstances a slug or border member 41 of the same thickness is inserted between faces 37 and 35 of gauge members 30 and 29 respectively, as shown in Figure 9. Such insertion of the slug or border member 41 rauses a lateral movement of the gauge member 29 and likewise, a lateral movement of the group of trial slugs 42, as inclicated in Figure 9. A guide plate 44 is then moved in a manner such that its guiding surface 45 engages and is made flush with the sawed edges of the slugs 42, as indicated in Figure 10. In said figure it will be noted that the distance between the zero line and the guide face 45 will correspond to the thickness of the border member 41. The trial slugs 42 and the gauge members 29 and 30 have now served their purpose and may be withdrawn from the table 20 and in their place may be substituted the mitering attachment as shown in Figures 3 and 4 and which includes a main bod ortion 46 having an angled face 47 corresponding to the angle of the engaging faces 34 and 36 of the miter gauge members 29 and 30, respectively. This body member 46 is provided with a dowel pin 48 which is received by an opening 49 in the table 20 when the flQIlt body member face 50 of the body member 46 engages the 7 front gauge member 26. A' movable jaw member 51 is pivotally connected to the main body portion 46 and is provided with an angular face 52 corresponding with that of the face 47 and when brought into operative position engages one side of a bundle of borders 53 while the face 47 of the 46 engages the other side of said bundle or border members 53. The border members 53 in. their angular position are then pressed up into engagement with the guiding surface 45 of the side guice member 44, as shown in Figure 3. The border members 53, together with the mitering attachment, are clamped between the stationary and movable jaws 26 and 28 preparatory to mitering the border members 53. With the border members 53 arranged as shown in Figure 3, the ends of the border members 53 will be cut at the proper angle to match each other and at the same time remove the minimum amount of material.

From the above description it is apparent that the gauge members 29 and 39 are used first to establish a zero pointand then to' set one of said gauge members by moving it a predetermined distance corresponding to the thickness of the borders to be mitered, whereupon the side guide member 44 is moved into proper position for subsequent cooperation with the border members clamped in the mitering attachment and to be mitered.

This miter gauge may be used in another manner, as illustrated in Figure 11. In such case the bundle of scrap slugs 54 is pressed up against the front gauge member 26 and the side gauge arm 27 and then cut by the saw to establish the zero point. The gauge members 29 and 30 are then moved into engagement with the sawed edges of the bundle of slugs 54 with a slug or border member 55 inserted therebetween, which slug 55 corresponds to the thickness of the borders to be mitered. The side guide member 44 is then moved into engagement with the gauge member 39 where it is secured by the set. screw 56 whereupon the slug or border member 55 may be withdrawn, permitting the gauge member 29 to move into the dotted line position shown in Figure 11. The bundle of slugs 54 may now be removed and the mitering attachment 46 applied as before,

cut pressed into engagement the with straight guiding surfaces 32 of the gauge member 29, whereupon after the border members are clamped the latter may be cut and trimmed at the proper angle for matching the beveled surfaces and wasting a minimum amount of material.

The side guide member '44 is provided with an elongated slot 57 through. which the with the ends of the borders to be set screw 56 extends and also is provided with a groove 58 which receives a longitudinally extending tongue 59 on the bracketmember 60 which is secured to the table 20 by a set screw 61. A slot 62 in the overhanging end portion 63 or" the bracket tit) receives the stud (51. The stud 56 for clamping the side guide member ll in position extends and is screwed into the bracket The guide member ii and bracket- 60 may be removed as a unit without changing the adjustment by simply loosening the crew 61.

By means of the mechanism hereinabove described border members and the like may be accurately trimmed regardless of their thickness and their variation in thickness from a standard thickness. Furthermore, the standard graduated miter gau s which at times will not give a proper s ting because of the variation in thickncsso't the border members to be cut varying from the standard thickness, can be eliminated.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.
