8 Claims.

This invention relates to a lining and beveling machine, primarily designed for the use of engravers, and has for an object to provide a machine in which the work clamp is arranged to be bodily adjusted across the table so that work having a substantially large area may be clamped throughout its length.

Another, object consists in providing such a machine in which the alining gauge may be extended and adjusted across the table in position to coact with the work clamp.

.A further 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.

Fig. 6 represents a detail plan View of the alining gauge and adjacent parts; and

Fig. 7 represents a detail elevation of the same. This application is a division of my copending application filed May 29, 1929, Serial No. 367,008.

The machine includes a base I arranged to be held in position by suitable lag screws, or the like, 2. From the base uprises a pedestal 3 to which is pivotally secured, as at 4, a motor support 5, on which is mounted a motor 6 by means of bolts 1. This motor receives a belt 8 which is designed to actuate parts hereinafter described.

A bracket arm H is fixed to the side of the pedestal 3 projects upwardly therefrom in two angular directions, as clearly shown in Figs. 1 and 2. The upper end of the arm ll carries a cross head I3 which is provided with two wheels l6 and serves as an anti-friction support for one side of a carriage l8 which is reciprocated during the operation of the machine. The other side of the carriage is supported by a V-shaped rail l9 that is secured to the pedestal by bolts 20. -The means for reciprocating the carriage I8 55 includes a hand wheel 2| which is fixed to a rod 22 that is journaled in a swinging bearing 23 which is carried by a bracket 24 fixed to the side of the carriage. The construction and operation of the parts thus set forth is clearly shown, described and claimed in the application above mentioned and further description is not deemed necessary since it forms no part of the present invention.

The table which directly carries the work is denoted by 49, and is secured to the carriage l8 by screws 50.

The clamp for securing the work to the table consists of a clamping member 60 which is substaritially the same length as the table, and is mounted for vertical adjustment in ways GI, 62 that are disposed to slide on and project upwardly from the opposite ends of the table. The lower portion of the ways BI and 62 are arranged to overhang the opposite edges of the table 49 and are provided with inwardly projecting tongues 6l* and 62* respectively, of which the tongue 6|* is arranged to slide in a groove 6l** in one edge of the table, while the tongue 62* slides in a groove 52 in the other edge of the table. A spacing bar 63 connects the ways BI and 62 and gives rigidity thereto while the tongues 6I*, 62* are slidably held in their respective grooves in the opposite edges of the table. The face of the clamping member 60 is provided with a pair of racks 64 that are designed to mate with gears E fixed on a shaft at that is mounted in the ways 6! and 62. This shaft 66 has one end furnished with a worm gear 61 that meshes with a worm 08 fast on a shaft 69 that is vertically journaled in a lateral projection on the way 62 and is operable by a hand wheel M.

It will thus be seen that the clamping member is raised or lowered in a perpendicular straight line movement by turning the hand wheel 10 in one direction or the other, and it may be added that the under face of said clamping member is preferably fitted with a pad of leather, or the like, in order to avoid injury to the work, since the clamping member is adapted to engage the entire length of the work on the table.

The machine also includes means for bodily moving the ways 6!, 62 carrying the clamping member 60 laterally across the table, and this means consists of a pair of threaded rods ll, each of which has one end mounted in bearings 12 fixed to opposite portions of the table 49. The threads on the said rods mesh with interiorly threaded sleeves 13 that are bolted to ways BI, 62. In order to actuate the rods "H, a shaft 14 .is mounted in bearings 15 which depend from bearings I2. Each end of the shaft 14 has a spiral gear 16 fixed thereto and said gears mesh with spiral gears TI that are fixed on rods II. A crank handle I8 is secured to an end of shaft "I4, and it will be seen that the turning of the said crank handle will correspondingly turn rods 'II in the threaded sleeves I3 so as to feed the ways 6|, 62 and connected parts, laterally across the top of the table and hold the ways in their adjusted position, as shown in dotted outline in Figs. 2, 3, and 5.

This means for thus moving the clamp laterally and holding the same with respect to the table facilitates the use of the machine on various occasions, particularly where a single plate containing a group of pictures'is being worked upon and it is, for instance, desired to line the boundaries of the individual pictures disposed throughout the area of the plate.

It is desirable that there be provision for a slight vertical adjustment of the table with respect to the carriage in order to provide for variation in depth of cut accomplished by the tools, and this is satisfied by a wedge-shaped slide 79 that intervenes between an inclined ledge 80 at the rear of the carriage and the adjacent horizontal under surface of the table 49. The slide has a pair of slots 8| formed therein to accommodate screws 82 that are threaded into the carriage, and these slots permit longitudinal movement of the slide by means of a nut 83 that is threaded on a stud 84 which projects from the carriage. A rim 85 on the hub of said nut rides in a kerf formed in the side of the slide 19, whereby turning movement of the nut 83 will move the slide in one direction or the other with respect to the carriage and table fixed thereto, with the result that the table may be given a slight vertical adjustment in relation to the carriage. This adjustment is permitted by springs 53 which are arranged on screws 50 that secure the table to the carriage as hereinbefore described.

The cutter head for the bevelling and, if desired, channeling tool is of a well known and approved form. It is denoted by 86 and is mounted on a spindle 81 which is journaled in a bifurcated standard 88 that is carried on the upper part of pedestal 3. A pulley 89 is fixed to spindle 81 intermediate the arms of the biiurcated standard, and is intended to be embraced by belt 8 which leads from the motor, as hereinabove described. The tools in the cutter head 86 may be of any well known or approved form for the purpose in hand. 7

The machine also includes a head for a variety of lining tools, or the like, which is indicated generally by 94. The detailed construction and operation of this head for the lining tools appears in United States Letters Patent granted to me jointly with Vernon E. Royle, under date of May 22, 1917 and No. 1,226,912, so that the same will not be shown or described herein.

The said head is fixed on a slide 95 and has its side edges beveled, and is mounted in an under cut track 96 that is carried on a support 91, which is rotatably mounted on a stud 98 that projects laterally from the side of standard 88. This rotatable mounting enables the tool head 94 to be swung into operative position or swung upwardly and rearwardly to inoperative position. The top of one side of track 96 is formed by a separate piece marked 99 that is traversed by screw I which is threaded into the body of the track. Thus, the part 99 serves, under the influence of the screw, as a clamp to grip the edge of the slide 95 and hold the tool head 94 in its desired adjusted position. In order to provide for very accurate adjustment of this part, a sleeve IN is adjustably fixed to slide 95 by a screw I02 which is yieldingly held in any desired position by spring I03. The said sleeve I M carries an adjusting screw I04 which is threaded therein and fitted to abut the track 06. A micrometer gauge I05 is provided on screw I04 for precise work.

It will be seen that, when it is desired. to adjust the head 94, the screw I02 may be loosened and the slide 95 moved over the top of the table to approximately the desired position, at which point screw I04 will be in abutment with track 95. Screw I02 is then set, and the precise ad justment of head 94 accomplished by turning screw I04 that is provided with a micrometer gauge. When the exact adjustment is obtained, clamp screw I00 may be tightened to hold the parts firmly in position.

The lining tool, or the like, carried by the head 94 when in operation, is angularly disposed so that the line cutting can be done on the forward stroke of the table at the same time that the beveling is accomplished.

The machine is further equipped with an alining gauge which includes a slide I01. that has beveled side edges which are mounted in an under cut track I08 rotatably mounted on a boss I09 that projects laterally from an arm I I0 which is cast integrally with a support III which is bolted to and projects from the side of pedestal 3. Said rotatable mounting of track I08 enables the gauge to be swung into operative position, as shown in Figs. 6 and 7 and into inoperative position, as shown in Figs. 2 and 3.

The forward end of slide I0! has a T-head I I2, in the ends of which are fitted trunnions I I3 that carry a frame I I4 which supports a gauge proper H5. The latter is provided with the usual serrated edge to facilitate its use in exactly predetermining the line to be cut on the work. A guard H0 is carried on the slide I01 and fitted to receive and cover the serrated edge of the gauge proper when the latter is not in use. This protection is obtained by swinging the frame I I4 on the trunnions II3 until the gauge proper II5 rests in the guard H0.

The construction of the parts for permitting adjustment of the gauge is the same as thatjust described in connection with the cutter head 94 so that it will be sufficient merely to indicate the parts by number. The separate clamping member of the track is marked II! and its screw IIB. The sleeve on the track is denoted by H9, its clamping screw by I20, the spring for the latter by I2I, the micrometer adjusting screw by I22, and the micrometer by I23. It will be understood that these parts are arranged and operated in the same way as the corresponding parts associated with the cutter head 94 and its slide 95. This provision for extensive as well as precise adjustment of the gauge across the top of the table proper oo-operates with the adjustability of the work clamp 00, hereinabove described, to facilitate operation upon plates where it is desired to cut lines at a distance from the edges of the plates as, for instance, when a plate including a group of pictures is being operated upon. In order to prevent the gauge from striking a blow upon the table when it is swung into operative position, I provide a stop I24 which is carried by the track I08 arranged to engage an abutment I25 on the arm IIO when the gauge has reached 15 its operative position immediately above the table.

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 restate 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 efiiciency, accuracy and speed in operation, together with general adaptability for meeting the varying needs of this particular class of work.

It will be evident 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.
