, 2. The table and clamp are mounted to carry the plate to be operated upon into and out of engagement with the beveling cutters 3 fixed in a head 4 mounted on a spindle '5 journaled in a bearing 6 anddriven by means of a band pulley l from a suitable source of power (not shown). A

bracket 8 is secured to the bearing 6 by'bolts 9 and serves as a support for a turret having a plurality of lining cutters mounted on the bracket in rotary adjustment, so as to bring any one of the several cutters into operative position at pleasure.

The turret consists in the present instance of a hub Ill provided with a plurality of arms ii, iii, I3 radiating therefrom, the outer ends of the arms being turned at an angle to their inner portions so as to occupy positions substantially at right angles to the radii of their mounting.

The hub II) is positioned to rotate on a vertically disposed stud I l fixed in the bracket 8. The outer end of each of the arms ll, I2, I3 is provided with a socket I5 within which is fixed a sleeve I6 by means of a set screw H (see Fig. 2).

This sleeve I6 is exteriorly screw threaded at 17' to receive one end of a micrometer gauge I8,

while the other end of 'the gauge has a screw threaded engagement at I9 with a conical bushing 20, in which is journaled a spindle 2| of a swinging cutter support 22.

The spindle 2| has a conical surface it which coacts with a correspondingly interiorly tapered seat 24 in one end of the bushing 28. The other or outer end of the bushing is provided with a tapered interior seat 25 disposed in the opposite direction from the seat 24 and arranged to receive a conical follower 26 keyed at 21 to rotate with the spindle 2 I This follower 26 is yieldingly held in position by means of a spring 28 housed in a cap 29 having a screw threadedengagement with the outer end of a bolt 30 longitudinally disposed in the spindle M. This cap 29 is locked in its position on the bolt 30 by a nut 3| The bushing 20 is mounted to slide longitudinally in the sleeve I6 and is prevented from turning therein by a tongue and groove connection therebetween, of which the tongue 32 is fixed in the sleeve I6 and the longitudinal grooveSS is formed in the bushing 20. Thus; it will be seen that, while the bushing 20 may be moved 10ngitudinally by the rotation of the micrometer gauge 18 on the sleeve I6 to give lateral adjustment to the cutter support 22, the swinging movement is controlled by the frictional contact of the coni oeive an offset 4'? on the cutter.

cal interior seats of the bushing and the tapered portion of the spindle 2i and conical follower keyed on the spindle.

This construction of the cutter support and mounting insures the steadiness of the cutter when in action and conveniently retains the support in such swinging adjustment as it may be placed in by the operator when the cutter is out" of engagement with the plate. v p

In order to register the lateral movement of the cutter support 22 by means of the micrometer gauge I8, I provide a collar 3&- having a is provided with a thumb piece 14 for the con venience of the operator in pressing down the cutter to its work. I

The cutter 45 is secured to its support by means of a slanting groove 46 arranged to re- This offset 41 extends longitudinally along one side of the cutter and permits the cutter to slide longitudinally along the groove in the support 22 in an oblique direction toward and away from the plate 48 to be operated upon so as to bring the point only. of the cutter into engagement with the plate.

The cutter is held in its position on the support by means of a cheek piece 49, the upper end of which has an offset 50 on its inner face to hold the body of the cheek pie ce away from the adjacent portion of the support 22, and at its lower end the cheek piece is provided with a V-shaped groove 51 adapted to engage the outer face of the cutter 45 and a portion of the back of the cutter. The check piece 49 is clamped to the support 22 by means of a stud 52 fixed therein and having its outer end screw threaded to receive a nut 53. Y

The depth of the cut is regulated to the greatest degree of accuracy by means of a presser foot 54 disposed in close proximity to the cutting point of the cutter 45. This presser foot 54 is fixed to a plunger 55 arranged to slide vertically in the support 22 and is prevented from turning by means of a guide pin 55 mounted to slide in a hole 51 in the bottom of the support 22. The presser foot Ed is yieldingly held at the limitof its upward movement by a spring 58, one end of which rests on the bottom wall of a recess 59 formed in the support, while the upper end engages a collar 60 pinned to the plunger 55.

The position of the presser foot 54 with respect to the plate 48 is controlled by a member 6| having a screw threaded engagement with a rotatable shaft 62, one end 53 of which. is mounted in the support 22 and the other end 64 journaled in an arm 65 extending upwardly from the support 22. i

A thumb nut 66 is pinned at 61 to the end 54 of the shaft 62 so that by rotating the thumb nut the shaft will move the member Bl longitudinally thereon. This member is provided on its lower face with a longitudinal channel 68, the bottom 59 of which is inclined throughout its length, and arranged tov receive the upper end of the plunger 55 of the presser foot 54 so that the longitudinal movement of the member on the shaft will move the plunger and presser foot in a vertical direction against the tension of the spring 58.

The member 6| has scribed on its outer surface a zero point 10 which may be secured in position on its shaft 62 by means of a thumb screw H having a screw threaded engagement with the arm 55 and arranged to impinge against the portion of the shaft which is journaled in the arm.

In order to accurately predetermine the position of the presser foot with respect to the point of the cutter, I provide a gauge 12 in the form of a flat plate having a series of graduations I3,

T4, l5, l6 scribed on its faces, which graduations are designed to register with the zeropoint 10 on the member 6|. 7

This gauge 12 is removably mounted in vertically disposed recesses 11, i8 formed. in a carrier 19 mounted to slide on a rod having one end 8| fixed in the support 22 and the other end 82 carried by the arm 65. The carrier 19 islocked in position on the rod 88 by means of a thumb screw 83 having a threaded engagement with the carrier and arranged to impingeupon the rod 80. Thegauge I2 is frictionally held in the recesses TI, 78 of the carrier lilby means of a flat spring 84 housed in the recess H and arranged to frictionally contact with one edge of the gauge.

The cutter 45 is designed to cut a groove in the plate, which groove will have a flat bottom and outwardly inclined side walls. The cutting point of the cutter has a horizontally straight bottom cutting edge 85 and

side cutting edges

86, 81 inclined upwardly and outwardly from the bottom cutting edge. The side cutting edges 86, 81 are formed with substantially the same degree or angle of inclination with respect to the bottom cutting edge, so that in operation the width of the groove is governed by the depth the plished when the cutter has reached a depth of one sixty-fourth of an inch in the surface of the plate.

The cutting faces of the series of cutters are shown on an enlarged scale in Figs. 11 to 19 inclusive, and are inscribed with the legends particular widths of grooves the cutters will cut in the plate.

The cutter having the legend 1, shown in Fig. 11, may be operated to cut grooves having itsinitial cut in the form of a scratch of very narrow width and slight depth to a groove havinga' depth of at least one sixty-fourth of an inch and a width substantially equal to the depth.

The cutter'l shown in Fig. 12, is designed to cut an initial groove equal to the maximum width of groove cut by the cutter 1 and may be operated to cut grooves increasing in width until the cutter has reached its maximum depth of one sixty-fourth of an inch.

likewise, the cutter I shown in Fig. 13, has

an initial. cut equal to the maximum cut of the cutter I and the maximum width cut is controlled by the depth of the cutter entering the surface of the plate to the limit of one sixtyfourth of an inch.

The cutter I also follows the cutter I to increase the width of groove, while the cutters I --I --I -I' --I follow consecutively to provide cutters for progressively wider grooves than that cut by the cutters II I I but all the cutters are limited to the same uniform depth to produce its maximum width of groove.

To facilitate ease in operation and to indicate to the operator the cutter in use, as well as to position the presser foot with respect to the cutter, provide the gauge plate 12 above the graduations, with the characters corresponding to the characters on the cutters.

In the present instance, the series of graduations "It on the gauge plate it are numbered 0, l5, 3d, and t5 and the characters II --I I disposed, respectively, above the numerals. The series of graduatiens M are designated by the numerals d5, 65, E5, and 90 and register with the characters I -I -I -I respectively. The series of graduations '55 are inscribed with the numerals at, H55, H28, and i3 5, and the characters I -J I register with the numerals 90, N35, and 520 respectively. The series of graduations iii carry the numerals 935, 2553, N36, and 88d and may be used to register the cut of any one of the cutters shown and described or any similar lining cutter.

As previously described, the zero point it on the member 6! registers with the graduaticns on the gauge plate 12, and by reason of the inclined bottom 6% of the channel 68 in the member and its coaction with the plunger of the presser root, any longitudinal movement of the member 6! on its shaft 62 will cause the zero point it to change its position with respect to the gradu ations and also control the position of the presser foot with respect to the point of the cutter.

Assuming that the cutter I is disposed in the support 2?, as shown in Fig. 3, and it is desired to increase the width of the groove to be cut, the shaft 62 is manipulated by the thumb nut til, so that the member 6! will be moved to the right. In this movement the inclined bottom 6-? was brought to another position with respect to the plunger, and the plunger urged upwardly by the tension of the spring 58 between the collar 5% and arm 2'2. This upward movement of the plunger carried the presser foot 54 away from the point of the cutter, thereby allowing the cutter to out deeper into the surface of the plate. By the cutter entering further into the surface of the plate, larger cutting surfaces with the inclined side cutting edges 86, iii, in addition to the bottom cutting edge were brought into use, thus widening the distance across the groove.

To reduce the width of groove to be cut in the plate, the thumb nut 66 is manipulated to move the member 6! to the left, so that the inclined bottom 69 of the channel 68 will press the plunger 55 downwardly against the tension of the spring 58 and the presser foot E3 closer to the point of th cutter, thereby limiting the depth the fiat bottom cutting edge 35 and the inclined side outtingedges 88, ill may pierce the surface of the plate. Thus, the movement of the member 6i regulates the width and depth of the groove to be cut, and the position of the member with respect to the gauge is readily visible to the operator so that he may accurately determine the position of the presser foot with respect to the cutter so as to cut a Wider or narrower groove.

From the foregoingit will be seen that any number of grooves of a predetermined width or of different widths may be cut on a plate or a number of plates more accurately with a single cutter, and the pressure applied by the operator on the thumb piece 44 to rock .the lever 38 and the supporting arm 22 to actuate the cutter to cut the grooves cannot cause the cutter to pierce the surface of the plate any deeper than the presser foot will allow by its contact with the plate.

By this construction, the cutter may be brought intoand out of operation by a short oscillating movement of the lever, and the cutter, when disposed in its operative position, is located almost beneath its center of oscillation so that any liability of the cutter to chatter is obviated.

It will be understood that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; and hence I do not intend to be limited to the details herein shown and described, except as they may be included in the claims.
