PANTOGRAPH ENGRAVING-MACHINE.
SPECIFICATION forming` part of Letters Patent No.. 655,750, dated August 14, 1900. Application iiled January 4, 1900. Serial No. 343. (No model.)
To all whom, t may concern:
Be it known that I, MARK BARR, of The Linotype Vorks, Broadheath, in the county of Chester, England, have invented certain new and useful Improvements in Pantograph Engraving-lvlachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention relates to improvements in pantograph engravingmachines, more especially to those capable of dealing with three dimensions-length, width, and depth-by a swinging and vertically-moving tracer and tool.
r Referring to the accompanying drawings, which are to be taken as part of this specilication and read therewith, Figure 1 is a perspective view of a machine made according to the present invention, but with ordinary vertically-adjustable pattern and work tables. Fig. 2 is a perspective view of the pivotal block between the stem of the tool and the telescopic lever. Fig. 3 is a perspective view of the pivotal block between the tracer-rod on the one hand and the rocking bar and tracer-rod and tool on the other. Fig. et is a perspective View of a machine with swinging pattern and work tables made according to the present invention.
1 is the base of the machine, and 2 is a central standard.
3 is a horizontal rocking bar, supported in bearings 4 4, carried by the standard 2 and In these bearings it is capable of a reciprocating circular motion about its longitudinal axis.
5 is the tracer-rod, and 6 the tracer-point.
7 is the tool, and 8 the tool-spindle.
The tracer-rod 5 is connected to the bar 3 by being led through a block 9. This block is held to the bar; 3 by being pivoted to it within a cavity 10 by pivots 1l, the axial line of which is at right angles with but in the saine horizontal plane as the axis of the rocking bar 3. The tool-spindle 8 is connected to the bar 3 in exactly the same way as the tracer-rod 5-@1 e., by being led through a block 9, held to the bar 3 by being pivoted to it Within a cavity 10a by pivots l1, the
axial line of which is at right angles with but in the same horizontal plane as the axis of the rocking bar 3, and therefore parallel with the axial line of the pivots 11 above mentioned. The lateral motion of the tracerpoint 6 is conveyed to the tool 7 by means of a link 12, the ends of which are shown as forked, to the more conveniently connect with the pivots 13 and 13a of the blocks 9 and 9,
` respectively.
Referring to Fig. 1, 14 is the pattern-table, fast on a bracket l5, capable of vertical adl justment on a slide 16, fast to the base l and the standard 2 by means of a traversing screw 17. 18 is the work-table, fast on a bracket 19, capable of vertical adjustment on a slide 20, fast to the standard 2 by means of a traversing screw 2l.
The construction of pattern and work table just` described does not form any part of the present invention.
The tool-spindle 8 is carried by and turns in a bearing 28 in the end of a bracket 29, standing up from the top of the standard 2.
The vertical motion of the tracer-point 6 and tracer-rod 5 is communicated to the toolspindle 8 by a telescopic lever 22 23. This lever is situated above the rocking bar 3. It
'has its fulcrum 26 in the said bar by being passed through a block 24, which is capable of being slid along the portion 22 of the lever `and of being slid longitudinally along slots 25` 25 in the end of the bar 3, duly forked to receive the said block 24 and slots 25. The position of the fulcrum 26 is adjustable lengthwise of the rocking bar 3 by means of the locking-nut 27 on the trunnions, one on each side of the block 24, which engage in the respective slots 25. The fulcrum 26 above described is always on the side of the tool-spindle S opposite to the tracer-rod 5. The toolspindle 8 is pivotally connected to the portion 22 of the telescopic lever 22 23 by being passed through the block 30, which hangs by pivots 3l down through a hole 32 in the said portion 22 and enters the bore of the block 9a. The block 30 is connected to the toolspindle 8 by any suitable means which will allow of the said spindle 8 turning freely in it and of also holding the spindle 8 to the block 30, so that the up-anddown motion of IOO the latter will take the said spindle' up and down with it. The said means may include a capacity for adjustment along the length of the spindle.
37 is the tool-spindle driving-pulley.
The tracer-rod 5 is pivotally connected to the telescopic lever 22 23 in the following way: The outer end of the portion 23 of the telescopic lever 22 23 has a fork 33. 34 is a sleeve vertically adjustable upon the rod 5 by a set-screw 35 and carrying a trunnion 36 on each side of it, the two pivoting in the respective prongs of the fork 33. The axes of the pivots 36 and 31 are parallel with each other and with those 1l 11a of the blocks 99, already described.
The present invention includes means by which' the pattern-table may be set at any angle with the horizon about a fixed center and means by which that setting will effect the setting of the work-table at a corresponding anglo about a like center.
Referring to Fig. 4, 14 is the pattern-table. It is mounted centrally upon a spindle 37, which is fast to it and which rocks by means of a ball-and-socket joint 3S in a bracket 39, standing up from the base 1. The spindle 37 iits telescopically in a socket 40, standing up vertically from the end of a rod 4l, parallel with the axis of the rocking bar 3 and capable of a to-and-fro sliding motion in guides 42 42, which are fast on a bar 43, adapted to slide at right angles with the length of the rod 4l upon V-guides 44 44, fast on the said base 1. The socket 40 is connected to the respective ends of the rod 41 by a ball-and-socket joint 45. 46 is a spindle centrally fast to and depending from the worktable 1Sa in the same way as the spindle 37 is fast to and depends from the pattern-table 14% lt rocks by means of a ball-and-socket joint 47 in the bracket 48, projecting laterally from the standard 2. The spindle 4G fits telescopically in a socket 49, the bottom end of which is connected by a ball-and-socket joint 50 to the respective ends of the rod 4l in the same way as the socket 40 is connected to the respective ends'of the said rod. 51 51 are set-screws for holding the bar 43 in its adjusted position upon the V-guides 44 44, and 52 5.2 are set-screws for holding the rod 41 in its adjusted position in the guides 42 42.
