BEVELING-VIACHINE.

SPECIFICATION forming part of Letters Patent No. 598,257, dated February 1, 1898.

Application filed August 1 8 94.

To all whom it may concern:

Be it known that I, VERNON ROYLE, of

. Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Beveling-Machines, of which the following is a specification.

My invention relates to an improvement in beveling-machines, and more particularly to that class of bevelers which are employed in connection with half-tone plates, which leave a proving-bearer surrounding the beveled j edge of the engraving, which bearer can be removed at will by hand or by the aid of a pair of pliers, according to the depth of the cut. In plates of this character their thinness renders them peculiarly liable to bow up under the cutter, and the danger of inj uring the engraved surface attendant upon using ordinary forms of clamps has rendered it difficult to produce a satisfactory beveling machine.

The object of the present invention is to provide means for overcoming the difficulties Fig. '3 is a top plan view, the table being re-` moved. Fig. 4 is a top plan view of the table in detail. Fig. 5 is an end view of the table, showing a portion of the carriage in section. Fig. 6 is a partial'view, in front edge elevation, of the table. Fig. 7 is a top plan view of the clamp and portion of the table. Fig. S is a view in vertical transverse section through the clamp, its operating-shaft, and a portion of the table. Fig. 8a is an enlarged View, in end elevation, of the mechanism for supporting and adjusting the gage, which is located on the machine-frame. Fig. 9 is an enlarged view in detail of the gage carried by the table for squarin g the position of the plate. Fig. 10 is a view in face elevation of the gagesupporting plate. Fig. 11 is a view in end elevation of the gage and its supporting-plate. Fig. l2is a partial view, in rear elevation, showing the means for adjusting the table vertically. Fig. 13 is a face view of the cutter-head with cutters in position. Fig. 14: is an edge view of the cutter-head, showing the Serial No. 519,986. (No model.)

means for securing the cutters to the head. 5 5

Figs. 15 and 16 are partial plan and sectional 'views of one of the plates, showing the bev eled grooves cut therein. Fig. 17 is a top planview of the machine with certain of the parts broken away to show more clearly other parts beneath them; and Fig. 18 is an enlarged view in detail, showing a partial vertical section through the table along the central portion of the sliding plate G.

The pedestal on which the working parts of the machine are mounted is denoted by A and is made heavy and rigid to prevent torsional strain and other derangements incidental to uneven and settling floors. It is provided with a door a, opening into its hollow interior, which latter is employed as a store-room for tools. i

The table for supporting the parts to be opn erated upon is denoted by B and is supported 'upon a carriage B, mounted upon the said which intermeshes with a bevelgear c2 on a screw-threaded shaft c3, which engages a nut c4, fixed to travel with the carriage.

,The table B is provided on its under side with an elongated recess b2 for the reception of the head d of an arm projecting froma rock-shaft D, journaled in the carriage, and provided with an operating-arm d', projecting from the shaft at an angle to the arm cZ and under the control of a thumb-screw d2 to rock the shaft and thereby slide the table transversely withrespect to the travel oi' the carriage. A spring d3 is employed to hold the arm d against the end of the adj usting-screw cl2, and the tension of the spring da is intended to be sufficient to rock the shaft D and slide the table in one direction-wiz., the direction opposite that in which it is forced by the turning down of the screw d2.

.The table B has an additional adjustment vertically with respect to the carriage B for IOO the purpose of moving the work toward or away from the cutter, and hence increasing or decreasing the depth of the beveled groove. This adjustment is effected by means of a wedge-shaped bar E, which rests and slides upon a beveled seat e at the rear of the carriage, with its upper horizontal edge engaged with the rear edge of the table. The wedgeshaped bar E is held in position by means of screws e, which pass through elongated slots e2 in the bar and enter the rear of the carriage. The barE is moved longitudinally with the greatest accuracy by means of a thumbnut e3, which engages a fine screw e4, fixed in the end of the sliding bar E. The nut e3 is held againstlongitudinal movement by means of a collar on its hub which loosely engages a support e5, fixed relatively to the bar E, so that the nut e3 may rotate freely in either direction, and hence while held against longitudinal movement itself force the screwe4, and hence the bar E, Ain one direction or the other, as may be desired.

The table B4 is secured to the carriage by means of a single bolt F, which extends through an enlarged opening f in the carriage and thence into the under side of the table, the bolt having inserted between its head and the carriage yielding washers f, so as to permit the swaying movement of the bolt F in the carriage a distance sufficientto permit the transverse adjustment of the table with respect to the carriage and a vertical yielding movement sufficient to permit the vertical movement of the table hereinabove referred to. rlhere is also preferably ametallic washer f2 located between the head of the plate and the yielding washer or washers f to give the bolt-headr a more extended bearing on the yielding washers.

Lost motion due to wear between the head CZ of the double operating-arm and the walls `of the elongated recess b2, in which it engages,

Ymay be taken' up by means of a sliding plate G, located in the under side of the table and under the control of an adj Listing-screw g to move it longitudinally and a clamping-screw g to hold it fast to the table, the end of the plate Gr being located at the wall of the recess in the under side of the table, so that the recess may be narrowed slightly at the point where the head CZ enters it.

The plate to be operated upon is clamped yto the table by means of a vertically-movable clamp H, mounted at its ends in sliding adjustment in standards Zz, uprising from the table B,and provided with a pair of rackbars Zt which mesh with inions h2 on a ro' tary shaft h3, mounted in said uprising standard 7L and operated by means of a worm i on an operating-shaft I, provided with a handwheel fi', the said worm 'L' engaging a wormwheel h4 on the shaft h3. The lower or operating face of the clamp is preferably made broad to give it an extended bearing upon the plate to be held.

For placing the work in the proper position on the table B With respect to the cutter, to

be hereinafter described, I provide two gages, one of them, K, secured to the supportingframe and the other, L, mounted on the table. The gage K is fixed in the present instance .b f set-screws 7o toa swinging frame Zr )ivotally secured ecceutrically to the ends of a rock shaft or bar 7a2, which latter has adjustably fixed thereon a sleeve k3, provided with a collar 104 for turning the shaft k2 and thereby throwing the gage K a greater or lesser distance over the rear edge of the plate to be operated upon. The sleeve 7a3, which carries the shaft 7a2, is mounted in the upper end of a supporting-standard 705, which standard is split at its upper end and provided with a set-screw k6 for the purpose of clamping the To relieve the concussion when of which is in position to be engaged by a lug 7a, fixed to rock with the swinging frame Zr' `and so located that the said lugk1G will strike the spring k7 just before the gage reaches the limit of itsforward swing.

The gage L is fastened by screws Z to a swinging support Z, fixed to the rock-shaft Z2, provided with an actuating-spring Z3, ,the tension of which tends to keep the gage depressed, With its sharp edge Z4 in the bottom of the beveled groove. The gage Z4 may be lifted from its position in the groove by means of an operating-handle Zw, fixed to either the gage-supporting piece Z/ or to the shaft Z. The rock-shaft Z2 is mounted in the supporting-piece Z5, removably-secured to the face of the adjustable supporting-plate Z6, provided with a dovetailed tongue ZT and a tapered tongue ZS, adapted to fit in corresponding grooves extending lengthwise of the table BC The plate ZG is clamped in the desired adjustment longitudinally along the table B by means of a thumb-nut Z9, which enters a screw secured to the dovetailed tongue Z7, or, as I prefer, the tongue Z7 may be the head of the screw itself, the screw extending from the head or tongue Z7 through the plate Z6 into engagement with the nut Z9. The gage L is used after the first groove has been cut in alinement with the gage K and serves to locate the second cut exactly at right angles to the first eut for the reason that the edge of the gage L is set at right angles to the edge of the gage K, and the gage L is made to follow the vertex of the V-shaped groove rst cut inloeating the plate on the table for the second eut. In the same manner the Vthird and fourth cuts may be squared or located exactly at right angles to the previous cuts by em- IIO adjusting the plate on two cutters and for this purpose is provided with grooves m and m', extending across the face of the disk, for the reception of the cutters lss riage bodily in its own plane, a table mounted O and O, respectively. The cutters are held in position by means of bevel-faced clamps P and P', the faces of the said clamps toward the cutter being straight, while their faces toward the opposite walls of the grooves are beveled, as shown at p and p', to correspond tothe beveled walls of the grooves. The clamping-pieces P and P are forced inwardly to clamp the cutters in position by means of set-screws Q Q', the threaded ends of which engage threaded perforations in the clamping-pieces P P. Y

The plate with its grooves cut therein is denoted by R, its groove in one direction by r, and the groove at right angles thereto by r. The particular form of the groove which I prefer to cut is of a general V shape in crosssection, with a steeper portion r2 at the upper portion of the wall adjacent to the central portion of the plate. groove is not, however, a matter of essential importance, as the cutters may be employed to simply rabbet the edge of aplate or grooves of other forms in cross-section," as may be found desirable.

l. In a beveling-machine, the combination with a cutter-head and cutters carriedthereby, of a carriage, means for moving the Vcaron the carriage in position to support the plate to be operated upon, means for moving the table bodily forward and backward in a direction transverse to that in which the carriage moves and means for raising and lowering the rear edge of the carriage beneath the cutters while the opposite edge retains its position upon the carriage, substantially as set forth.

2. In a lieveling-machine, the combination with the cutter-head and cutters, of a carriage, a table mounted on the carriage in position to support the plate to be operated upon, a tapered adjusting bar or platelocated between the carriage and that portion of the table beneath the cutters, an adjusting device for advancing and withdrawing the tapered adjusting bar or plate for raising or lowering the rear edge of the table beneath the cutters, while the opposite edge retains its position upon the carriage and means for moving the table bodily forward and backward transversely to the movement of the carriage and independently of the said adjusting device, substantially as set forth.

The particular form of 3. The combination with the cutter-head and cutters, of a table for supporting the plate to be operated upon, means for advancing the table, along the path of the cutters, an an gle-lever having one of its arms engaged with the table and an yadjusting device engaged with the opposite arm of the angle-lever for moving the table transversely to its movement along the path of the cutters, substantially as set forth.
