Specification of Letters Patent.

Patented Oct. 16, 1906.

Application led October 19, 1905. Serial No. 283,507-

To all whom it may concern:

Beit known that we, HANS LraBREIcn and LLEwELLYN D. LoTnRoP, citizens of the United States, residingr at Gloucester, in the county of Essex and Sta-te, of Massachusetts, have invented certain new and useful Inc provements in rToys; and we do hereby declaro the following to be a full, clear, and exact description of' the invention, such as will en able others skilled in the. art to which it apw pertains to make and use the same.

This invention relates to improvements in toys, and particularly to a momentum-actuated device.

One of the objects of the invention is the production of at-oy which is comparatively inexpensive to construct and owing to its peculiar operation is of great amusement and interest to the operator.

Another obj ct of the invention is thev production ot a toy which is gravity-actuated on its downward movement for obtaining suiii cient momentum to reverse and travel upwardly iartly or entirely the distance which it traveled vin the rst inst ance.

A further object is the construction of a toy constituting an exercising` device'whereby the operator thereof will obtain material benefits resulting from exercising of his arms and other members of the body.

A still further object of the invention is the construction of a toy which is suspended from a liexible member-as, for instance, a cord-and owingr to its peculiar construction may be allowed to travel downward the length of the cord and then travel up the cord its entire length or part of its length and subset uently repeat such movement.

Titli these and other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter lrully described, illustrated in the accompanying drawings, and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a view in side elevation of our preferred device constructed in accordance with the present invenrieu. Fig. 2 isa transverse vertical central scci tional view of the structure depicted in 1. Fig. 3 is a. side view of an embodiment similar to the embodiment depicted in Figs. 1 and 2, except the spokesifwheel or toy are curved and positioned tangentially to the hub.

Referring;r tn the drawings by numerals, 1 and 2 designar the sections ofthe toy, which are connected, preferably, by a transverse pin 3. Each section is provided with a laterally-extending hub portion 3a, which portion. is of greater diameter than said pin 3. Each section is provided with substantially straight spokes 4 and with a comparatively thick rim 5. The rims 5 of the, device are of such size as to sullicieutly weight the device, so that the el'liciency of the operation will be materially increased. In one of the sections, preferably l, an aperture 6 is formed in a spoke 4, through which aperture is threaded a flexible member-as, for instance, a cord 7.

The cord or string 7 is preferably wound around the hub et the device before it. is released l'rom the hand of the operator. After the string has been wound arc und the pin or hub 3, Fig. 2, the operator should grasp the free end of the cord 7 and release the device, which will immediately move downward by gravitation. This downward movement will consequent-ly unwind the. cord 7. As the cord 7 unwinds, owing to thc weighted structure of the devicc--to wit, the rims 5-the momentum of the device will increase until the device has traveled the entire length of the cord, and then the momentum will be sufficient to reverse the movement of the device to cause the same to travel upward, finding the cord upon the pin 3. Vhile the upward movement of the toy need not be suiicient to normally wind all of the cord. upon the pin or hub portion 3, if a slight upward jerk or the cord 7 is made at the time the cord has completely unwound the momentum of the device will then be sufficient to travel upward to the hand of the operator, and consequently rewind all the cord upon the hub or pin 3. From practical experience it has been found that this rewinding of the cord can be coutinued for a long period, if desired. However, if the operator only suspends the toy without endeavoring to completely rewind the cord upon the pin or hub 3 the weight of the toy is suflicient to cause a reciprocating vertical movement of the same severai times before the momentum of the device is overcome by `qravitatiom although of course it is gravity that primarily actuates the device IOO on. its downu-nrd movement, hy which it 'f her threaded through said aperture and cagains st :jiieient momentum movement of sind toy, (musing the sinne to to reverse. the

rewind port or :ill oll the cord :il'ter it liasl traveled downward the entire length of the` j cord tions, :is :it (i, :ind threading :he cord through pablo of heiner wound or coiled around Said transverse. ineniher.

'2. In :i device of the. character described, the. coinhiuution of seetioiis, euch sect-ion comprisingr :i huh portion, spokes integral mi to the. :iperturnig of one of the secthis :ipenured portion, thecord een he wound c-:nried hy the huh portions and hxedly seevenhv upon the pin or huh oi the device which would not he the ease if the eord was tied to the huh hetween the sections.

In the embodiment depicted in Fig. :3 subf staintiziily the sinne str" ,nre is involved :is

in the einhodiineut depicted in Figs. l :ind 2,

with. tite exception that each of the sections are pro-vided with the curved spokes Alf,

4 which terminate :it their outer end ii. a spherical portion S, which is not only formed for g ornamental purposes, but also to provide the. device with inore weight for increasing g the. etteieney of the operation, as it wilt he obvious that the heavier the sections the greater the momentum obtained dnilng the downward travel or unwinding of the coiled vided with :in aperture. formed there-iii coittiguous tothe hub portion, a transverse nienz ber positioned within sind huh portionsl find connecting sind sections, and a, flexible nien;-

wir h seid huh port ion, one ol` siiid spokes pro- `vided willi un aperture, :i tire or rim integrati with the outer ends` oi' sind spokes, meains curing the seiztions together, :i lexihle ineinher threaded through said :iperturedspoke and adapted to he coiled between said seotions.

3. In :1 device of the. character described, the. eomhiuiition of sections, each section comprising ii huh portion, spokes integral with the inner ends of each of said huh portions, :i piu extending through sind huh portions, said pin of less diameter than said hub portions, seid huh portions extending?r laterally from the spokes and constituting reinforcingr means, wei ghted tires er rims integral 'ith the outer ends of said spokes, one of said spokes provided with an aperture. formed therein contiguous to the huh portion, sind :i flexible nieinhcr threaded through said aperture. und capable of being coiled around said pin.

In testimony whereof we :iflix our signa.- tures iii presence of two witnesses.
