This invention relates to toy? lie detectors;

The primary object of the" invention is topro vide a toy having an indicator hand or needle with which a heat and moisture-responsive de?` Vice is associated to effect operation of the irl-- dicator hand or needle, the position of the indicator hand or needle at thefextreme left Asignifying truth and the shift of the indicator :hand or l needle to the extreme right indicatingfth'atf'a question asked has beenl answeredialsely;v f

A further object of the inventionzis to provide a toy lie detector wherein-there is provided a casing of a size to be convenientlyfheld airrthe hand of the user. with a window openingin lthe top wall of the casing throughwhich; apilvotally vmounted indicator handv or needle is visible; An operating strip within-thecasingfor,the1inf dicator hand or needle may vbeconstructedbf any material desired, such as.Cellopl'Iane;Cel-y luloid, cellulose acetate, or a.Y combination of such materials, so that when a portion of the: handiof the user, such as a thumb, `is placed" in proximity of said strip, the heat and moistureV of, thefhand will be transmitted through .a seriesfof perfora` tions in the casing toact yuponthe--strip and leffect movement thereof for theA operation lofthe indicator hand or needle. With the above and other objects-gin view that will become apparent as the naturejof-therzinvvention is better understood, the samec'onsi'sts in general of certainnovel details of: ,construc-t tion and combination of parts hereinaftery, more fully described, illustrated in :the accompanying drawing and claimed.

The toy lie detector comprises -a casingof aj I size tojbe conveniently gripped in thehand vand isof elongated formation, the bottom portion'ofY 10? the casing-comprising a bottom wall I0, side walls IIl and I2, respectively, and end walls'l3." The `cover for the casing comprisesaltopwali IA having a depending marginal' flange I5 overlying the upper'edge of they side and end walls yof 15'- the-bottom section of the casing. An arcuate window openingv I 6 extends transversely -ofl one end of the top wall I4, and as shownv in Figures land; fingers Il' 'bent' from the edge walls of said window opening IIz pass through a.\Cello-. 20 t phane ,or4v like sheet I8 at the underside -of the topvwall AI4to be bent into grippingengagement withYY saidV transparent sheet for retaining the lattergin position as-illustrated.

g The, mechanism within thecasing includes an 2,5 indicatorhand or needle and mounting there-V forfthe latter comprising-a base plate vI9 secured at opposite side edges thereof to the bottom wall IIU- by-Welded soldered or like strips 20 extending transversely of the bottom wall I0 of-'the 30, casingas clearly shown in Figures 2, 3` and- 6.

AA pairof opposedupstanding guidelflanges 2I riseirom -the base plate I9 adjacent the side wall` I2of`the casing, the base plate I9 being cut-v away between said yflanges 2l as shown vin Figures 3,5' andgfi. A U'shaped support comprising upper and lower

horizontal legs

22 and 23 connected by 'a yerticalleg 24 has the lower leg 23 slid into positionbeneath theguide anges 2i and into the cutg-away'portion in th-e base plate II) between 40 said flanges 2|.

*The 'U-shaped support constitutes ra lbearing for vthe'indi'cator hand or needle,`the latter cornprisingfa centralv plate portion'ZS carrying at one sidethereof 'between the upper and lower "ends 45 an 'offset cylindrical barrel 26 in which'a vertical. bearing pinvr 21 is xed, the upper and lowerprojectingy ends of the bearing pin respectivelyhaving ,freei bearingmountings in the upper and

lowerhorizontal legs

22 and 23`of the `U-shaped 50 support. `One side of the central platev 25 at the upper edge thereof .carries an elongated indicator hand or finger 28, while the other side of said plate 25 intermediate -the upper and lower ends,thereofr carries an arcuate arm 29, the bear-4v 55 ing for the indicator handl or needle being adjacent the side wall I2 of the casing While the outside arc of the arm 29 is adjacent the side wall I2 of said casing. 'Ihe mounting for the indicator hand or needle and the construction of the latter are such as to cause the arcuate arm 29 to normally lie adjacent the side wall I2 of the casing while the arrow head 28a of the indicator hand or finger normally lies adjacent the side Wall II of the casing and at the left-hand side T of the window opening I6.

The operating means for the indicator hand or finger comprises a strip formed of any :plastic material desired that is capable of transmitting heat and moisture, `and such material may comprise Cellophane, Celluloid, cellulose acetate, or a combination of these materials, such a strip of material being indicated by the reference` character 3D underlying the arcuate arm 2,9 of the indicator hand or needle. The holding means for the heat and moisture-responsive strip 30 comprises a metallic plate 3| slidably anchored to the side wall I2 of the casing by means of flanges 32 overlying opposite side edges of the plate 3| with the anges carried by a base plate' 33 secured as by solder at 34 to the side wall I2. The upper side edge of thevplate 3| has a notch 35 cut therein into which `the depressed end 36 of the adiiacent flange 32 ispressed to hold the plate 3| against longitudinal sliding movement. The end of the plate 3| overlying the baseplate 33 is bent at right angles as at 31 to"provide an abutment or stop for the indicator handle or needle 28 that is shown in its dotted linelposition in Figure 2 las engaged with said 'stop 31. The other end of the metallic plate 3| overlying the adjacent end of the heat and moisture-re? sponsive strip 38, together with the adjacent portion of the side wall I2, as shown inFigure 7, has coacting dents or depressions `V3Ia-fo`rnied therein for gripping the adjacent end 'of the heat and moisture-responsive strip 30. The free projecting end of the heat and moisture-responsive strip 30 is reinforced and inclosed by a folded ply oi light material 38. As shown in Figures 1 and 3, the side wall I2 of the casing in line with the heat-responsive strip 38 is provided with a plurality of perforations 39 to facilitate the passage ofvheat and moisture from the hand of the user.

The normal positions of the indicator hand or needle 28 and; arm 29 are shown by full lines in Figure 2, the arrow head 28*1 of the indicator hand or needle being at the 'end of thefwindow opening I'I indicated at T'in Figurel to signify truthJ In the use of the toy the casing is gripped in the hand' anda question isasked,the thumb of the user overlying the series of openings `39 in the sidewall, heat `and moisture of the thumb are transmitted through said openings to the heat and moisture-responsive strip 30, the latter inthe presence of heat and moisture flexing or bending to assume the dotted liner-position shown at 3|)a in Figure 2, movement of the strip Sil moving the arcuate arm 29 ofthe indicator hand or needle to shift the `sameto `the dotted line position shown in Figure 2, the. indicator hand `or finger moving on its pivot'pin 2T to the dotted line position shown in Figure'z "to the right-hand end of the slot indicated at"L in Figurei to signify the telling Ora fanehoed; of course, the indicator hand or llinger always moves 'to the righthand side of the window opening I6, the device being a toy and notin any man'- ner being operative as a scientiilc device or mechanism to indicate the telling of a truth or lie.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, and while there is herein shown and described the preferred embodiment thereof, it is to be understood that minor changes may be made in the details of construction, such as will fall Within the scope of the invention as claimed.
