TOY OR WORKING MODEL.

Specification of Letters Patent.

Patented Oct. 24, 1916.

Application filed April 12, 1915. Serial No. 20,719.

- set forth in the following specification.

The present invention relates to games and toys, and particularly is an improvement in that class of devices by which small engineering models are made up from standard separate parts, which parts are capable of being taken apart and remade into other toys or models.

Many of the models which it is possible to build by the use of these perforated plates, strips and other elements simulate devices having moving parts, such as windmills, merry-go-rounds, ferris-wheels, etc, which it is sometimes desired to operate continuously. It is also frequently desirable to have available a relatively large amount of power, as where it is desired to run a model lathe or a number of models at the same time.

Heretofore spring motors have been employed to supply the power for working models of the character described, but these require rewinding at frequent intervals and do not, to'that extent, answer the purpose where continuous motion or considerable power is desired. of these motors is a rather laborious and trying operation, especially for small children. Electric motors have also been heretofore employed, but those available have been very expensive; and water motors have also been used, but the field of their 'OPBIMSIOII has been limited. In addition, neither the electric nor the water motors have been constructed compactly enough so that they could be effectively built into the models for which they furnished the motive power.

VVit-h these considerations in mind the objects of the present invention are to provide a unitary electric motor structure, which is cheap, simple and compact in construction,

which is so designed as to cooperate with the perforated plates and strips of the constructional model system, which can be readily and effectively built into the same, and which supplies a. large amount of continuously Further, the rewindingavailable power that can be applied, shut off and reversed by operating a switch.

The invention will be better understood by reference to the accompanying drawings, illustrating one expression of the inventive idea, and wherein Figure 1 is a perspective view of a windmill made up of perforated strips and plates in combination with the unitary structure forming part of the present invention; Fig. 2 is a plan view of the unitary structure of which an electric motor constitutes a component part; Fig. 3 is a perspective view of the structure shown in Fig. 2; Fig. L is a side elevation corresponding to Fig. 3, the flanges shown along the top edges of the side perforated plates in Fig. 3 being shown in full lines in Fig. at; Fig. 5 is a plan view of the structure shown in Fig. at; Fig. 6 is a drawn-out or extended view of the switch mechanism employed; and Fig. 7 is a diagrammatic view showing the circuit connections.

Referring to the drawings wherein like reference numerals indicate like parts, 10 and 11 are side plates which are preferably permanently securedv in spaced relation to each other by upper tie-rods l2 and 13 and lower tie-rods l4 and 15 to form part of a motor unit. Side plate 11 is provided along its lower longitudinal edge with a flange 16, preferably formed integrally therewith, which flange is uniformly perforated at 17. The side plate 10 is similarly constructed, perforations 18 being provided in a flange 19 corresponding to flange 16. Each side plate is provided at its right hand end (Fig. 3) with a number of series of vertically disposed perforations, the perforations of the first series being indicated by the numeral 20, that of the second series by the numeral 21, and that of the third series by'the numeral 22. The perforations of each series are spaced apart the same distance as perforations 17 and 18 in flanges 16 and 19, and this spacing is the standard uniform spacing which is employed throughout the system of units of which the models are con structed. Each series is spaced apart the same distance as the distance between the holes of any one series, or spaced apart a distance corresponding to any multiple of the distance between any two of the holes. \Vhile threeseriesof perforations 20,21 and 22 are-herein shown-at the "righltiof Fig. 3,

it will be understood that any desired numat their extreme left with a series of spaced perforations 23, uniformly ar a support for a disk 45 of suitable insulating material, on which disk are mountedfourranged in accordance with the system fol.- lo-wed. If desired, the side plates 10. and 11 may be, and preferably are, provided along their upper longitudinal edgeswith flanges 24 and 25 (Fig. 5), the former being provided with uniformly spaced perforations 26, and the latter with similar perforations '27. The provision of the flanges 16, 19, 24

and 25, perforated according to the system fo-11owe'd,-enables the structure'to be readily used in combination with other plates, strips and elements which are perforated according "to the same system and all of which are used inthe building of constructional models, as will be more fully set forth hereinafter.

From the foregoing description, it wil be understood that the side plates and the flanges thereof are provided with perfora- ,tions which are spaced to a standardization that is common not only to the plates themselves but to the other elements with which "-the plates are intended to be combined. The

plates are provided with a plurality of rows of perforations spaced as aforesaid, and the several rows are arranged angularly with relation" to each other so that the perforations of the plates can register with the perforations of the other elements in any of a Variety of Ways.

The principal elements of an electric motor aremounted between said side plates 10 "and 11. As herein shown, the tie-rods 12 and 13 support an upper, laminated steel pole-piece 28, and the lower tie-rods 14 and 15 support a corresponding pole piece. Be-

tween these pole-pieces is mounted a suit- ""ably wound electromagnet 29, and rotating between said pole-pieces is a suitably wound armature 30 mounted on a shaft 31, which latter projects through side plate 10. A commutator 32 of any suitable construction is electrically connected to said armature 30,

brushes, which springs hold the brushes continuouslye in contact with the commutator segments, I In the manner here described, the principal elements of an electric motor are separatelythat is independently of each othermounted on the plates 10 and 11.

Current for the energiz ation of the electromagnet is supplied by one or more bat teries 39 (Fig, 7) the terminals of which battery or batteries are electrically con- 48 by conductor 55.

nected to binding screws 40 and 41 mounted,

,respecti-vely on side plates 10 and 11 A suitable switch mechanism is employed for turning on, shutting off, and reversing the current, and, as here shown, this switch mechanism is mounted on a bracket 42 which is secured in'place between plates 10 and 11 by screws 43. A stud or screw 44 provides binding screws to which are secured terminals 46, 47, 48 'and'49. This disk is maintained in a fixed and stationary position, but the terminals thereon engage arc-shaped contact members 50 and 51, carried by a rotatable member 52, also mounted on stud 44, which member is rotated by handle 53.

For the sake of clearness, none of the circuit connections are shown in Figs. 1-6 inclusive, but such connections are graphically illustrated in Fig. 7 Preferably a series wound motor is employed for the reason that such a motor gives greater starting torque. As will be observed from an inspection of Fig. 7, binding post 41 is connected to commutator brush 35 by conductor 54, and commutator brush 3.6 is connected to terminal v Terminal 49 is, connected to one end of the winding of electromagnet 29 by conductor 56, and the other, end of this winding is connected to terminal 46 by conductor 57. Terminal 4'? is connected to binding screw 40 by conductor 58.

It will be observed that when the rotating switch element 52 is moved to the position indicated in Fig. 7, that is, with the segment 50 connecting terminals 46 and 47, and the segment 51 connecting terminals 48 and 49, the current will pass in one direction through the magnet 29. On the other hand, if the switch element 52 is rotated so that segment- 50 ngages terminals 46 and 48, and segment 51 engages terminals 47 and 49, the current will pass through the magnet 29 in the opposite direction, and the direction of rotation of the armature shaft 31 will be reversed. If the switch element 52 is moved to an intermediate position, that is, when each segment only contacts with one terminal, the circuit will be opened, and the armatureshaft 31 will cease rotating.

Referring particularly to Figs. 2 and 3, it will be observed that the end of armature shaft 31 projects through side plate l0, ashereinbefore stated, and that a collared pulley 59 is secured .to said shaft in any suitable manner, as by a set-screw 60. If desired, the power of'the motor can be taken off of the armature shaft 31 directly, through the intermediary of this pulley 59, or in any other desired manner. As shown. in Fig. 5, acord 62 passes about said pulley to transmit motion to any desired point.

which belt rotates the windmill arms 62 in the desired direction, dependent upon the position of switch element 52. It is not, however, always desirable to take the power directly from the armature shaft 31 and hence, according to the present invention, means are provided for introducing between the armature shaft and the point of application of the power, a train of gears. These gears may be mounted on shafts such as 63 and 6 1. These shafts are adapted to have bearings in any of the holes of series 20, 21 and 22, and the number of the holes of these series, and their uniform and standard spacing, enables one or more of such shafts 63 and 64 to be placed in any desired position, with the result that, by the introduction between said counter shaft or counter shafts and the armature shaft 31 of the desired gearing, any increase or decrease of speed of rotation of the'driven shaft can be secured.

As shown in Fig. 3, a pinion 65 is mounted on the projecting end of armature shaft 31, which pinion meshes with a gear 66 carried on counter shaft 63, which counter shaft 0 projects through the top hole of each of the two series of perforations 22 in the side plates 10 and 11. The other projecting end of counter shaft 63 carries a pinion 67,

which meshes with a gear 68 carried by counter shaft 64, which latter is shown projecting through the top holes of the series of perforations 20. Shaft 63 and the gearing carried thereby are held in place by screws and collars 69 and 70, and shaft 64 is similarly secured in position by collars and set-screws 71 and 72. In the construction illustrated in Fig. 5, a rope 73 is' wound on said counter shaft 64:, and said rope is wound and unwound on said shaft, according to the direction of rotation of the armature shaft, at the desired speed.

As will be observed by an inspection of Fig. 1, illustrating, as an example, a windmill, the side plates 10 and 11 are mounted on a perforated rectangular shaped flanged plate 74:, the perforations in the plates 10, 11 and 14 being uniformly spaced according to the standard adopted. Plates 10 and 11 are secured in place by suitable retaining means 7 Perforated strips 76 support shaft 7 6 on which are mounted the windmill arms 62. The perforations in the rec tangularly flanged plate 74, exactly correspond with the perforations in the strips 76 and these parts are secured together by any suitable/retaining means passing through the alined perforations. The perforations 17 and 18 in flanges 16 and 19, exactly correspond, in turn, to the perforations not only in the rectangular shaped plate 74, but also to thosein the strips 76. It is obvious that numerous models may be constructed by the use of the present invention.

While for the purpose of illustration one expression of the inventive idea has been shown and described in detail, it is to be understood that the invention is not limited to the construction shown, but that the inventive idea is susceptible of various mechanical expressions within the limits of the appended claims.
