This invention relates to a lining and beveling machine, primarily designed for the use of photoengravers, and has for an object to provide such a machine in which the carriage and table are offset laterally from the pedestal, and the outer longitudinal edges of the carriage and table are rigidly supported throughout the entire length of travel in both directions, thereby permitting the M increase in speed of movement and minimizing the friction of the parts.

Another object consists in providing such a machine in which the support for the outer longitudinal edges of the carriage and table in their traveling movement includes a straight line parallel motion means connected to the pedestal and carriage and movable therewith, whereby greater accessibility of the work on the table is obtained.

Another object consists in providing certain improvements in the form, construction and arrangement of the several parts, whereby the above named and other objects may effectively be attained.

A practical embodiment of my invention is represented in the accompanying drawings, in which Fig. 1 represents a side elevation of the machine;

Fig. 2 represents a front elevation of the same;

Fig. 3 represents a detail vertical section, taken in the plane of the line III--III of Fig. 1, looking in the direction of the arrows;

Figs. 4 to 7 inclusive represent detail vertical sections, on a larger scale, taken in the plane of the lines IV--IV, V-V, VI-VI, and VII-VII of Fig. 1 respectively, looking in the direction of the arrows; and

Figs. 8 to 10 inclusive represent diagrammatic views of the straight line parallel motion means with the carriage shown in diiferent positions throughout its length of travel.

The machine includes a base I, a pedestal 2 uprising therefrom, a carriage 3, one longitudinal side of which is supported by a V-shaped rail 4 secured to the side of the pedestal by bolts 5, and a table ii for receiving the plate to be operated upon, which table is secured to the carriage 3 in any well known or approved manner, so that the carriage and table are reciprocated during the operation of the machine. The other or outer longitudinal side of the carriage 3 is supported by a straight line parallel means which comprises a series of links connected together and arranged to move about two centers of motion. The links l, 8, 9 and in are substantially of equal length and are pivoted together by bolts H, l2, I3 and M, in the form of a rhombus. The pivot bolt I t of the links '1 and I0 is also connected with the upper end of a link l5, while the upper end of a link I6 is connected with the links 8 and 9 by the pivot bolt l2. The links l5, it are substantially equal inlength, and the lower ends of the links are connected by a pivot bolt l! to oscillate in a bracket l8 carried by a plate l9, which is fixed to the side of the pedestal 2 by bolts 20. Thepivot bolt l3 of the links 9 and it connects the upper end of a link iii, the lower end of which is pivoted on a stud bolt 22 fixed on the plate IS. The links I, 8, together with their pivot bolt Ii, are secured in a bracket 23 fixed by the bolts 24, 25 to depend centrally of the longitudinal edge of the carriage 3.

In order to minimize the friction of the pivoted joints of the links, I provide anti-friction bearings of which the upper end of the link I has a ball bearing 26, while the upper end of the link 8 is bifurcated at 2'! (Fig. 4) and frictionally secured to the pivot bolt H, which is journaled in ball bearings 28, 29 carried by the bracket 23. The lower end of the link I is bifurcated at 30 (Fig. 5) and frictionally secured to the pivot bolt M which is journaled in ball bearings 3|, 32 carried by the upper end of the oscillating link IS. The upper end of the link II] which is also pivot-ed on the bolt [4 is provided with ball bearings 33.

Anti-friction bearings associated with the pivot bolt 52 and its coacting lower and upper ends of the links 8 and 9 respectively, and the upper end of the oscillating link !6, are similar to that shown and described with respect to the pivot bolt I4, links 1, l0 and I5, so that further description is therefore deemed unnecessary.- The lower end of the oscillating link E5 is provided with a ball bearing 34 which coacts with the pivot bolt ll, while the lower end of the oscillating link it is bifurcated at 35 and frictionally secured to the pivot bolt IT. The pivot bolt I'l is journaled in

ball bearings

36, 31 carried by the bracket l3, as shown in Fig. 7. The upper end of the oscillating link 2|, which is connected with the lower end of the links 9, I [i by the pivot bolt I3, is also provided with ball bearings (not shown) similar to the ball bearing shown described with respect to the links 1, l0 and pivot M, so that further description is deemed unnecessary. The lower end of the oscillating link 2! is provided with a ball bearing 38 which coacts with the pivot stud bolt 22 carried by the plate I9, as shown in Fig. 6.

As a result of the construction above described, it will be seen that the carriage is held in position and accurately guided by the rail 4, while the link means adequately support the other or outer longitudinal side of the carriage and permit its reciprocating movement with a minimum resistance.

The means for reciprocating the carriage 3 includes a hand wheel 39 which is fixed on a rod til that is journaled in a swinging bearing M which is carried by a bracket 42 fixed to the side of the carriage, as shown in Figs. 1 and 2. A screw bolt 33 serves as a pivot to permit the bearing M to swing in a vertical plane on the bracket 42. The rod 4%) pierces the adjacent side of the carriage 3, as indicated at M, and the inner end is furnished with a helical gear 65 that normally meshes with a rack 48 that is clamped by bolts 5 to the V-shaped rail 4 and hence is fixedly secured to the pedestal 2.

From the foregoing, it will be seen that turning the hand wheel 39 will slide the carriage on its rail and the link motion, by virtue of the engagement of the helical gear 25 with the rack 58 and with the hand wheel 38 and the con nected parts, will travel with the carriage 3 in its movement. This provides a very smooth and positive action because of the character of the intermeshing parts and the traveling movement a s with the table of the actuating gear 45 and connected elements. The helical gear, or the like, will always have at least two teeth in mesh with the rack because of the angularity of the teeth, which effects an even and precise movement;

1 and such an arrangement also allows the shaft which operates the helical gear to be placed at an acute angle to the rack, whereby its operating hand wheel may be convenient to the operator of the machine without being in his way. Furthermore, a gear of the helical type tends to prevent chips from clogging the rack, because the engaging movement of the parts is such as to urge the chips out of the rack instead of to hold them therein and crush them.

When the carriage with the table thereon is reciprocated in the operation of the machine from one position to another, the link motion will assume difierent positions such as that shown diagrammatically in Figs. 8 to 10 inclusive, and the links will move in the direction of travel, as indicated by the several arrows. The actuation of the carriage 3 transmits its motion through. the bracket 23 and its pivot bolt Ii to the links I and 8 which move the links 9 and is through the pivot bolts l2, l3 and 14. This movement of the links '5 to it inclusive and their pivot bolts Ii to M inclusive is transferred to the link 25 which is oscillated on its stud bolt 32 fast on the plate 19 which is fixed to the side of the pedestal 2. Simultaneously the links it and it will be oscillated on the pivot bolt ll journaled in the bracket it on the plate lit by their connections Hi and E2 of the links 1' to ill inclusive. Thus it will be seen that, by

r the co-operation of the several links with their pulley 5!! from a suitable source of power (not shown).

The clamp 5| for securing the work to the table is herein briefly stated as being capable of moving vertically toward and away from the work, the construction and operation of which is well understood by those skilled in the art.

The machine also includes a head for a variety of lining tools or the like, which is indicated generally by 52 (see Fig. '1). The construction and operation of this head for the lining tools is set forth in United States Patent No. 1,226,912, dated May 22, 1917, so that the same will not be detailed herein.

The operation of the various parts of the machine has been described in connection with setting forth their construction, so that it is not regarded as necessary here to re-state the operation of the machine as a whole.

It may, however, be noted that the construction and arrangement well adapts the machine for attaining the objects hereinabove outlined and others inherent in its construction, and that its design contemplates efficiency, accuracy and speed in operation, together with general adaptability for meeting varying needs of this particular class of work.

It will be understood that various changes may be resorted to in the form, construction and arrangement cf 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.
