PANToeRAPH-MACHINE.
SPECIFICATION forming part of LettersPatent N o. 538,776, dated May '7, 1895.
Application led April 25, 1894. l
To all whom t may concern:
Be it known that I, HARRY GRAHAM GRIER, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Pantograph- Machines, of which the following vis a specification. i
The object of my invention is to construct a pantograph machine by which a stone or metal plate can be engraved simultaneously with the tracing of the outline of the drawing, dispensing with the usual intermediate step of drawing upon the stone and engraving by hand or by a separate machine.
My invention also further relates to the arrangement by which a reduced or enlarged drawing can be made simultaneouslywith the engraving.
With these objects in view, myinvention consists in novel combinations of parts and details thereof, as hereinafter described and claimed.
In the accompanying drawings, Figure l is a sectional elevation of my improved panto- Fig. 2 is a front view of the table. Fig. 3 is a plan view. Fig. 4 is a section on the line 4 4, Fig. 3.
In Figs. l and 3, A is the` base of the machine and projecting from this base is a standard A having bearings a of. for the shaft B to which is hung the pantograph frame D. This frame consists of the bar a', which is mounted on and capable of swinging around the shaft B, a bar 0.2 secured to the bar a and parallel to it, and end bars o3, a4 which are parallel with each other. Abar a5 is secured to the bars o', a2 and is parallel with the bars as, a4. This'bar a5 is suitably shaped to carry an electric motor E. This electric motor is constructed in the ordinary manner and has the usual armature shaft e proviided, at its lower end,with a chuck e in which is secured` the cutting tool c. The motor is held securely vin place on the bar a5 by means of clamps e2.
Secured to the bar a5 is a bar f. This bar is hinged at f2 to a bar f which is secured to the bar a2. The barfis mounted on a pin p projecting from a Kblock p which rests in the Serial No. 509,021. (No model.)
slot in the bar d5, as shown clearly in\Fig. 4- and resting on the bar c5 is a p'lateo2 through which passes a clamp screw p3 which clamps the block to the bar of; The barf can be adjusted by inserting the pin p in any one of the openings]03 in the bar and the bar-f can also be adjusted on the bar 0.2.
Extending from the upper portion of the vertical shaft B to the points gg are supporting rods G G. These supporting rods and the main'bars carry the combined weight of the several parts that constitute the pantograph together with the engraving motor pens or tracing pens. I
On the upper end of the shaft B is a hand wheel B. The lo'wer end of the shaft B is screw threaded and adaptedrto pass through a screw threaded lug a on the upright A.
A collar b and a collar b on the shaft B support the pantograph frame so that by turning the hand wheel B the pantograph may be raised or lowered to adjust it in respect to the table. This shaft B can be locked in its adjusted position by a set screw B2, Fig. 1.
The main parallel bars a', a2 extend rearwardly as shown, and in the ends of these bars are holes ,i' so that the pantograph can be extended by removing the vertical shaft B and releasing the supporting' bars G G and moving the frame forward, so that the shaft will pass through the hole e' and the vpin g can be secured in the hole il and the pin g secured inthe hole i2 in the bar a. this arrangement the pantograph can be enlarged considerably.
The cross bar a6 is secured by pins to the main parallel bars a', a2 and serves to stiften the frame. A tracing point al maybe secured to this bar, as shown in Fig.'3, if necessary.
In the base A are two tables T T, and adapted to screw threaded openings in the base are adjusting screws n n so .thattthe table T may be raised or lowered to adjust it in respect to the pantograph. The table T is provided with radial slots tt', through which clamps s mayextend. Thus by this means any stone 6r metal plate can be clamped to sm y v e able parallel with vthe front edge of the base, name to this specification in the Ipresence of and provided with a plurality of thumb screws two subscribing Witnesses.
