TOY AIRPLANE Filed July 7, 1931 ,ululnnn/ Patented Apr. 26, 1932 Miran fs'rA ANTON r. women, or ennnsnn, I'DAHO TOY AIRPLANE Application filed July 7, 1931. Seria1 No. 549,250.

This invention relates to toys of the aerial type and of the character supported by a stand and around which the toyaircraf ts are adapted to travel and also ascend and dek'i scend during their travel, and has for the primary object, the provision of an improved operating medium for imparting movements to the toy aircrafts without the danger of said operating medium becoming tangled with the stand and which includes a novel type of weight adapted to automatically disconnect itself from the device when reaching its lowermost position so that the toy aircrafts may continue their travel by gravitation having first been elevated by the descent of the weight.

With this and other objects in view, this invention consists in certain novel features of construction,combination and arrange ment of parts to be hereinafter more described and claimed.

For a complete understanding of my invent-ion, reference is to be had to the following description and accompanyingdrawings, in which- Figure 1 is a side elevation illustrating a toy constructed in accordance with my invention.

Figure 2 is a fragmentary vertical sectional view illustrating the same.

Figure 3 is a fragmentary side elevation illustrating the'weight in theact of disconnectingitself from the operating'medium.

Figure 4 is a fragmentary perspective'view 7 fully of the weight and a portion of the operating medium.

Referring in detail to the drawings, the numeral 1 indicates a pedestal carrying a vertically disposed shaft or stand 2 to which is secured at the upper end thereof a shaft 3 provided with a squared portion 4 on which is secured a drum 5. A similar drum 6 is journalled on the shaft 3 below the drum 5 and the lower end bears against the upper end of the stand 2. A substantially arcuate shaped arm 7 is provided with the bearing opening intermediate its ends to receive and is non-rotatably secured to the upper end of the stand 2. The ends of the arm 7 are bifurcated and have journalled therebetween grobvd P 1 8 over which aretrained cables or flexible elements 9.- The elements 9 are wound upon the drum 6 and havetheir free ends connected by a weight bar 10 provided with a laterally disposed offset portion;

11 adaptedto, partially receive the stand' 2. A weight 12 consisting of elements'13 relatively spaced and connected by-an'arcuate shaped portion 14 are detachably secured to the bar 10 by hooks 15.

An arm 16 is journalled on'the shaft 3 intermediate the ends thereof and is secured like fasteners v1 7 the ends of the arm 16 ha'v ing journalled thereto grooved pulleys 18 a;

over which aretrained cables or flexibleelements 19;" The elements 19 are woundupon the dru'm5with their free ends attached-to toy aircrafts'20. I a 1 In operation, when the toy aircrafts 20 are in their lowermost position the weight'l2' is manually applied to the bar 10 which is then to the upper end of the drumb by bolts or in its vuppermostposition and due to-the -in+ fiuence of the weight, the bar lom'oves toward the pedestal 1 imparting rotation to the drum 6 which rotates the'arm 16 and winds the elements 19 aboutthe drumti imparting to the toy aircrafts a movement in a circular path -and in an upward direction. Asthe" bevelled ends of the weight 12 strike thesun face of the: pedestal 1, the -weight r ocks"and disengages thehooks '15' from the bar 10.

The weight of the toy aircrafts is then sufih cient to. cause them to gravitate'and (this movement causes a rotation of the arm'16 in a reverse direction unwinding the elements 19 from the drum 5 and winding the elements 9 onto the drum 6 sojthat torepeat the-operation of the device, the weight 12'is again man ually applied to'the bar 10, thus it will be seen that the toy 'aircrafts both travelin-a circular pathand descend'and ascend. Dur-' ing the movement of the bar 10- upwardly or downwardly relative to the stand 2, it is 'pre-f ventedfroin becoming tangled therewith due to the arcuate shaped portion 11 engaging one side of the stand 'whilevthe arcuate'shaped ferred embodiment of my invention, it will 7.

becoming tangled in their movements is entirely obviated either with the stand or with the toy aircrafts during their rotation either when ascending or descending.

Vhile I have shown and described the prebe understood that minor changes in construction, combination and arrangement of parts may be made'without departing from the spirit and scope of my invention, as claimed.

Having thus described my invention, what I claim is 1. A toy comprising a vertical stand, a shaft fixed to said stand and disposed vertically, a rotatable drum on said shaft, a fixed drum on said shaft, an arm j ournalled on the shaft and-secured to the rotatable drum, a second arm fixed to the stand, flexible elements wound on the fixed drum and trained over the ends of the. first arm and attached to toy ai rcra-fts, a second flexible element wound on the rotatable drum and trained over the ends of the second arm, a; bar connecting the free ends of the second named flexible element and adapted to have sliding relation to the stand,

and aself removable weight attached to the bar and adaptedto automatically disconnect itself from said bar when engaged with the base of the stand.

. 2.. A toy comprising a vertical stand, an

arm fixed, to the stand, a shaft fixed to the stand, rotating and non-rotating drums carried by said shaft, a second arm journalled on the shaft and secured to the rotating drum,

pulleys at the end of the arms, a flexible ele- V ment wound on the fixed drum and passed over said pulleys ofthe second named arm andhavi-ng its ends connected to toys, a second flexible element wound on the rotatable drum and passed over the pulleys of the first arm, a bar connected to the ends of the last named flexible element and having a curved portion disposed at one side of the stand, a. weight having an arcuate shaped portion stand, a pair of weights connected by an arcuate shaped portion disposed at the opposite side of the stand from the bar, hooks cardisposed at'the opposite side of the'stand v over-the bar and detachably connected to said bar, and'having rounded shaped portions adapted when engaging the base of the stand to automatically disconnect the weight from the bar.

v 3-. A'toy comprising a base, a stand carried by said base, a shaft fixed to the stand,

arm fixedto the stand, rotatable and nonrotatable drums carried by the shaft, a second arm journalled on the shaft and secured to= the rotatable drum, a flexible element wound on said fixed drum and trained. over the ends ,of the second named arm and hav: ing its'ends connected to toy aircrafts, a secondfiexible. element wound on the rotatable drum and trained over the ends of'the first named: arm, a bar' connected to the ends of the last named flexible element and having a curved portion engaging one side of the
