Patented Oct. 29, 1940 UNI-TED STATES Par- ENT; caries TOY". V MahlonAili Vinter, Chambersburg, Fa. -Appli cation February 10, 1940, Serial No. 318,349 n 3Glai-ms. .(o1.46-13o) 7 This invention-relates to improvements in toys orv animated objects and more particularly to toys of the type adapted to travel along an inclined cord or wire. V V
The primary purpose of the invention is to improve toys of this type so as to multiply interest in the movement of the toy.
Another object is to lsupplyatoy-of this'char- L acter-apparently having a willof its own and which will perform'spontaneously instead of proceeding with a purely mechanical regularity throughout the length of its journey.
With the foregoing and other objects in view, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.
In the drawing:
Fig. 1 is a side elevation of one form of the toy (simulating a monkey) shown suspended from the inclined string and with dotted lines indicating the movement of the device.
Fig. 2 is an edge view of the toy partly in longitudinal section.
Referring to the embodiment of the invention illustrated in Figs. 1 and 2, reference numeral 4 designates the body of the object having an integral upwardly extending arm or member 5 terminating in a supporting guide or hook 6 adapted to be hooked over a sloping supporting string 1.
The other arm or element 8 of the object also extends upwardly from the body but instead of being stationary relatively to the latter, it is pivotally connected to the body at 9 for movement about a horizontal axis. The arm 8 also terminates in a supporting guide or hook I0, which slidably engages the string 1.
In this form of the invention, the entire object is arranged below the string and in action the hooks 6 and ID will alternately move away from one another and then toward one another, so that the object will appear to descend the string with a very realistic step by step movement. To
increase interest in the toy, one of the legs II is pivotally connected at I2 to the lower portion of the body so as to swing about a horizontal axis as the toy proceeds down the string, and this leg is connected to the arm 8 by a link [3 so that the parts 8 and l I move in unison.
The other leg I4 is also pivotally suspended at l2 but there is a friction member [5 (Fig. 2) interposed between the parts 4 and Hi to normally prevent the leg M from moving relatively to the 55 body. Hence, this leg will function as an adjustable elementtobe-positioned by the operator to govern the weight distribution of the toy. In other-words, by swinging the leg l4 into a position' toward or away-from an-imaginary vertical line drawn through the center of gravity of .the 5 body of theztoy, the .pivot point 9 of the arm 8 will be moved toward'or awayfrom said imaginarytline', :therebyva'rying the speed of the toy andi the length of the stride. it takes as itgravitates down: the cordl. If'desired, the length of 16 each stride may also be varied by moving the pivotal connection 9 on the-body toward or away from the imaginary line drawn through the center of gravity of the body.
In operation, it will be understood that the 15 only necessary element required in the useof the object, is a sloping string or the like, and that sufficient tension must be maintained thereon to support the weight of the toy at the proper slope. After the string has been properly ar-- ranged, the hooks 6 and ID are caused to engage the string. The toy is then given a gentle swinging motion to cause the same to oscillate relatively to vertical lines which will pass, between the hooks as the toy moves along the string. In 25 other words, the toy willmove like a pendulum and the object will proceed down the string with a realistic step by step movement.
As before stated, adjustment of the leg M will vary the action of the toy. If this leg is moved 30 from a rearwardly position to' one more forward, this will result in an increase in speed and other interesting variations. As the slope and tension of the string also bear on the operation, interesting competitions can be run between different op- 35 erators to determine who can rig up the fastest toy and also who can make the longest endurance run.
For the scientific mind, the antics of the toy provide an interesting study. Basically, the toy operates as a pendulum with a different time period determined by its weight distribution to one side or the other of an imaginary vertical line drawn through the center of gravity of the body, which can be varied by manipulation of the frictionally pivoted leg M. The swinging toy sets up vibrations in the string and the latter obeys certain laws of vibration and has a definite period of its own depending on the tension, length, and position of the toy in this length. There are certain combinations of the above factors in which I the period of the toy and the string are such that mutual reinforcements of the two motions occur. At other times a dampening effect will be found. This alternate reinforcing and dama pening produces variations in the action of the toy that add to its life-like characteristics. Sometimes the toy will actually stop in its path and wait for more favorable vibratory conditions before proceeding. In other words, the toy will apparently have a will of its own and perform spontaneously instead of progressing with a simple mechanical regularity throughout the length of its journey.
It will be apparent to those familiar with the scientific principle underlying the invention that the toy may assume various forms, and it is not confined to the shapes disclosed herein.
While I have disclosed what I now consider to be preferred embodiments of the invention in such manner that the same may be readily understood by those skilled in the art, I am aware that changes may be made in the details disclosed without departing from the spiritof the invention as expressed in the claims.
What I claim and desire to secure by Letters Patent is:
1. A toy adapted to be used in conjunction with an inclined string and comprising a body, an arm rigidly united with and extending upwardly from the body, a string engaging guide connected to the arm above the body, another upwardly extending arm pivotally connected to the body, another string engaging guide connected to the pivoted arm above the body, a leg pivotally connected to the lower portion of the body, a link connecting the pivoted arm and pivoted leg to cause them to move in unison, and manually adjustable means pivotally mounted on the body for use in governing the weight distribution of the body, said means including a friction leg.
2. A toy adapted to be used in conjunction with an inclined string, and comprising a body member, a second member connected with the body and having a string engaging guide, an element pivotally connected to the body, another string engaging guide operatively connected with said element, and manually adjustable means pivotally mounted on one of said members and arranged mainly below the body member for use drawn through the center of gravity of said memher, and manually adjustable means on said memberfor varying the position of said pivotal pointwith-respect to said imaginary vertical line.
