JOHN C. BACKERT, F LYNBROOK, NEW YORK, ASSIGIIOR T0 MILLER SAW-TRIMMER COMPANY, OF PITTSBURGH, PENNSYLVANIA, A COBIPORATIQN 013 PENNSYLVANIA.
Application filed April 14, 1921. Serial No. 461,23.
To all whom it may concern:
Be it known that 1, JOHN C. BACKERT, a citizen of the United States, residing at Lynbrook, in the county of Nassau and State of K New York, have invented certain new and useful Improvements in Gauging Devices, of which the following is a specification.
My invention pertains to gauging devices for use in cutting the ends of type slugs, brass 1 rule or the like to a bevel.
In the patent granted July 26, 1921, to William M. Garwood, and numbered 1,385,- 782, for bevelling devices, there is described a device for use in bevelling type slugs, brass rule or the like, by means of which the slugs, or the like, to be bevelled may be made to project beyond the line of cut of the cutter just a sufiicient distance to permit the corners to be removed without interiering with the length of the slug, the device including means for thus spacing the corners of the slugs beyond the line of cut. The object of my invention is generally to improve upon devices of this character, and to provide such a device which can be especially quickly-and easily operated, which will be of a simple and strong construction, and which can be attached-to preexisting slug-cutting machines. Other special objects of my invention will appear from the following description, taken in connection with the claims annexed thereto.
By way of example, I have described one lib form of device in which my invention may be embodied in the following specification,
and shown such embodiment in the accompanying drawings, in which:
Fig. 1 is a plan oi a cutting machine for type slugs and the like, having applied thereto a gauging device constructed in accordance with my invention, the gauging device and the end gaugeoi the cutting machine being shown in the position which they occupy when the gauging device is being set to position for bevelling slugs two points in thickness;
Fig. 2 is a artial plan, of a diagrammatic nature, s owina the manner of using the gauging device for positioning the slugs priorto the bevelling cut;
Fig. v3 is a plan of the gauging device; Fig. 4 is a partial plan showing the bevelling device with the index head and index finger removed, to disclose the spacing meme her and the cam for operating the same; and
Fig. 5 is a longitudinal section, taken on the line 55 of Fig. 3, looking in. the direction of the arrows.
The gauging device of my invention is well adapted for use inconnection with a slugcutting machine such as is described in Harry G. Miller Patent No. 986, i85, granted March 14:, 1911, for Vises. Such a slug-cutting machine comprises a support carrying a fixed table 10 and a movable table 11, the latter being capable of being slid'to and fro to enable thework thereon to be operated on by a rotary saw 12 Mounted upon the sliding table 11 is a rest consisting of a side gauge 13, which is graduated pioas, and an end gauge 14 extending at right angles to the side gauge and slidable thereon, said end gauge carrying an adjusting worm 15, graduated to points engaging corresponding worm grooves in the side gauge 13,. The side gauge 13 is normally positioned at right angles to the cutting plane of the'saw 19f, but it may be swung so as to assume various other angles with such plane, the most frequently used angle, after the right angle, being that at which the side gauge extends at degrees from the line of the out oithe saw. To permit this swinging, the side gauge 13 has extending therethrough a follwer pin 13 having an arc-shaped extension rigid relative to the side gauge and adapted to extend into an arcshaped groove 13 formed in the. table 11, this groove being so arranged that when the side gauge is swung around, it will be moved in the arc of a circle having its center on the line of out of the saw 12*. A1001:- ing pin 13, inserted through the side gauge, fits in openings on the sliding table to lock the side gauge in the position to which it may be moved. A. vise co-operates with the side gauge and includes a vise bar 16, operated by handle 17. The end of the side gauge is squared so as to provide a surface 18 at right angles to the main slug-engaging surface 1.9 of the side gauge, againstwhioh surface 18 the slugs may be held when being bevelled for the second time, thereby obviating the necessity of turning them over and cutting them with the printing faces downward. On the fixed table 10 is mounted an abutment member 20 havinca slug engaging face 21 parallel the cutting plane of the saw, and having a shank 22 extending at right angles to said plane, the bottom of said shank being formed with a tongue 23 which slidably engages a groove 24 formed in the top of the fixed table 10, whereby the member 20 may be slid forward and backward with its face 21 maintained parallel with the cutting plane. A cap screw 25, passing through a slot 26 extending lengthwise of the shank 22, and entering one or the other of two holes in the fixed table 10, serves to hold the member 20 in any position to which it may be adjusted. The machine, as thus far described, is old and well known in the art.
If a plurality of slugs, previously cut to a predetermined length with their ends square, be placed as indicated in Fig. 2, engaging against the side gauge 13 swung into a 45 degree position, with their rear corners located on the line of the cut of.
the saw, and if a out be then made, it is obvious that the corners 0 of the slugs which project beyond the line of cut dc will be removed, and that the slugs b will thus be mitered without the predetermined lengths of them being changed. By placing the member 2O so that its face 21 is the proper distance from the line of cut d--e, it merely becomes necessary, in order to place theslugs b properly for the mitering out, to hold them against the face 19 of the side gauge 13 and shift them until their front corners engage the face 21 of the member 20*. With the slugs thus placed, and secured in position by the Vise bar 16 preparatory to the out, they will be accurately mitered with out any change length. It will be noted that the position of. the face 21 of the member 20 with respect to the line of cut d-e will vary in accordance with the thickness of the slugs to be cut. I
To provide for the placing of the memher 20 so that its face 21 will be in the proper position, with respect to the line of cut de, for the particular thickness of slug being mitered, I provide. the. member 20 with a plate 28, in Which slides, a spec ing member 29, such spacing member being adapted to extend'beyond the face 21 for a distance which can be made to accord with the thickness of the slugs to be mitered. l'f'the end gauge 14 be set to zero-i. e., to the position in which its face is located on the line of the cut of the saw (Fig. 1)- and-the member 20 be then slid up until the projecting spacing member 29 engages against said end gauge 14, then, if the spacmg member has been adjusted to project the correct distance for the particular thickness of'slugs to be mitered, the face 21 of the member 20?* will be in the correct position for spacing the corners of such slugs, in the manner above referred to, and indicated in Flga I 2.
nears-ea To provide for the required adjustment of the spacing member 29, l mount eccentric 30 in the plate 28, so as to be capable of being rotated on a stem 31 which enters said plate and is secured therein by a nut The reduced end 29"- of the spacing member 29 engages against the eccentric 30, and is held in such engagement by a spring 33, located in a recess 34 of the spacing member, which spring engages against a pin 85 extending upward from the member 20 at the part where the spacing member 29 projects therethrough. It is obvious that the turning of the eccentric 30 will effect an adjustment of the spacing member 29, cans ing it to project to a greater or less ex tent beyond the face 21. A. lmurled knob 36 is provided, by means of which the eccentric 30 may be turned, and beneath this knob 36, to cover the depression 37 of the plate 28 wherein the eccentric 30 lies, there is provided an index plate 38. The plate 38 is marked with a number of index lines denoting various common thicknesses of slug, one or another of which index lines come opposite a pointer 39, carried by the member 20 when the eccentric is turned by means of the knob 36. The index lines on the plate 38 are marked with numbers corresponding with the various thicknesses of slug. Thus, when the eccentric has been turned until the index line marked 2 is opposite the pointer 39, the eccentric will be in such position that the spacing member 29 projects the correct distance to position the member 20 so that its face 21 is properly placed for mitering two-point slugs.
In the use of my improved device-for instance, to miter four two-point slugs to make a square border,the four slugs are first cut at. each end to the predetermined length of he side of the square, the side gauge being in the right-angle position shown in Fig. 1; the end gauge is then moved. down to the zero position, and the member 20 is moved laterally until the spacing member 29, previously set for twopoint slug, engages the said end gauge, 14; the member 20 being thereafter locked by means of the cap screw 25; the end gauge 14 having been moved out of the way. and the side gauge 13 having been swung to the 45 degree position as shown in F ig. 2, the slugs are placed against the face,19 of the side gauge with their corners abutting against the face 21 of the member 20, being secured in such position by the vise and the first mitering cut made; and the slugs are lastly made to engage against the face 18" at the end of the side gauge, with the corners of their uncut ends abutting against the face 21 of the member 20 and the second mitering cut made. In this way, a border may be very easily and quickly made to any desired dimensions. Other very important uses of the device will be apparent to those skilled in this art.
An advantage of the device lies in the ease and speed with which the requisite adjustments may be made, as Well as in the strength and simplicity of the construction. A further advantage of the device is that it may be readily applied to pits-existing machines, without the necessity of any modifications thereof, or of any mechanical work thereon.
Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:
