PANTOGR-APHEC APPARATUS.

Applicationjled January 21, 1228. Serial No. 248,444;

This invention relates to theatrical appa-ratus and more particularly to the construction and control of an animated dummy to permit duplication of certainoperations performed by a concealed operator. i

An important object of the invention is to provide an apparatus whereby a dummy may duplicate cartoons or other drawings delineated by the concealed operator.

A still further object of the invention `is to produce mechanism for accomplishing these objects whicli'is extremely simple in both its construction and operation, which is readily manipulated andwhich will be durable and These and other objects I attain by the construction shown inthe accompanying drawings, wherein for the purpose of illustration is shown a preferredembooliment of my invention and wherein v Figurel is a side elevation partially in section showing theatrical apparatus constructed in accordance with niy invention; Y

Figure 2 is a section on'the line 2- 2 of Figure 1, the-dummy being illustrated in dotted lines;

Figure 3 is a. section on the line 3-*3 of Figure 1;' Y y Figure l isV a plan `view of the operators arm mechanism showing the coaction with the pattern; l,

Figure 5 is a'detail section-al view through one end of the control mechanism;

Referring nowv more particularly to the drawings, the numerals 10 and 11 indicate operators and dummys easels, of which the operators easel has clips 11 for interchangeably supporting panels 12 upon which patterns 13 are producedk for the guidance of the operator. Below the panel, the easel 10 has secured to one leg thereofa guide element 14,' the puipose of which will presently appear.'

The easel 11 has mounted thereon a transparent panel 15 and has secured thereto at its upperend and at its rear face a rotatable roller 16 supporting al paper roll 17, the web from which is passed overthe upper 'end ofthe easel and downwardly over the front face thereof and thence beneath the lower end of the panel 15 to afwindingroller 18. This winding roller has at oneend thereof a worm gear 19. Secured to the easel 11 ata point corresponding to the position of the guide lll of the easel 1() is a container 2O7 for the reception of ink or paint;

The easels 10 and 11 are preferably ai'- ranged adjacent opposite ends of a platform 21 and arising from this platform are Astandards-22 suitably bracedV to oneanother and to the platform. These supports are arranged adjacent the easels 10 and 11 and the support adjacent the easel 10 has secured thereto a bracket 23, through which is rotatably directed a shaft2t having at its rear end a. crank .25, and at its forward end, 'whichis rotatably directed vthrough a bracket 26 carried by the easel 11, a worin 27 for engagement with the` worm gear 19`of the winding roll 18, so that this winding roll may be rotatedto draw palper from the paper roll 17. The roll 16 supporting the paper roll has at its end a ratchet disk28 and the adjacent bracket 29 by means of which this roll issupported from the easel llmo-unts a pawl 30 releasable by a string 31 extended adjacentvtheeasel 10, by means of which the roll maybe locked against rotation. Ars the worm gearing employed for the operation of the winding roll likewise serves to lock this roll, itywill be obvious that the paper l may be drawn tightly across the face ofthe easelv and secured in this position. j

The upper ends of the supports 22 have' eX` tending upwardly therefrom spaced guides 32 between which ata point spaced below the lupper ends thereof are rollers 38. Mounted upon these rollerslbetween the guides 32 is an assemblage'comprising inner and outer tubular .shafts 341 and 35, of which the inner shaft 34; is of greater length than theshaft and has its ends` 'extended beyondthe ends there-- of. The outer shaft 35 has secured thereto spaced stop collars coacting with one of lthe pairs of .guides to limit longitudinal movement of the assemblage overy the rollers. Y lt will beobvious that this assemblage may be either rotated jvithin thelimits defined by these stop colars.

between the inner and outer shafts 34 and 35, the shaft Salis preferably'of less external diameter than theA internal diameter of the shaft 35 and the shaft 35 has mounted iii-itsV or longitudinally Vshifted In order to reduce frictional 'contact i ends bushings 37 in' which the shaftfl may be rotated. The outerends ofthe shaft 34 l have secured thereto an V.upper arm element 38, to the lower end of which isvpivotally connected,l as at 39, a forearm structure 40j both the upper arm and forearm elements prefer# ably consisting of flat plates. Theouter ends of the shaft 35 havesecured'thereto .short arms 41 connected by links42 to the forearm structure at a point spaced from the pivot 39 thereof, so that rotation of the shaft 35, While the shaft 34 is stationary, Will result in an oscillation of the forearm elements 40 about their pivots 39. It Will, of course, be obvious that. movement of the forearm or upper arm elements 38 or 40 at either end of the structure will be duplicated at the-opposite end of the structur. The arm structure at the forward end of the easel 11 is incorporated in and concealed by the clothing of a dummy 4,3., The end of the forearm structure is formed as the hand of the dummy and constructed to support a brush or stylus 44. The forearm element adjacent the easel 1()V is provided Wi th a stylus 45 constructed to co-operate with the pattern 13.` The pattern 13 employed is preferably provided by a groove or rib formed upon the panel 12 in the desired shape. The easel 10 and the associated arm mechanism may be concealedl tainer. 20. yThe stylus is then moved to the pattern and passed thereovei'. The operator through a suitably foi'med opening in the booth Wall and through the transparent panel 15 may observe the progress of the reproduction and in event of failure of the fluid of the stylus 44, may again dip this `stylus into the container 9.() to replenish the same. The pattern completed, the web may be` shifted to present aclean surface by manipulation of the crank.

It will be obvious that in moving the stylus 44 from the container 2() to the sheet, the entire mechanism should be shifted outwardly,

so that this stylus Will not contact the sheet until it arrives at the proper point.

Since theV construction hereinbefore set forth is capable of a certain range of change and modification Without materially departone of said tubes, forearm elements pivoted to the ends of said arms, respectively, rela-f tively short arms secured to the respective ends of the other of said tubes, links connecting the ends of each short arm toits adjacent forearm element whereby similar movements ving the ends of each short arm to its adjacent forearm 'element whereby similar movements are transmitted to said forearm elements, styli carriedby said elements for movement over the respective panels, acabinet enclosd ing the panel bearing the pattern `and the associated arm mechanisms of the-tubes and a dummy in an arm of which the `arm mechanism at the opposite ends of the tubes is included.
