PATNT oFFlcE MOTORIZED CONSTRUCTION- TOY Henry Pelton, New Britain, Conn., assignor to The Stanley Works,-New Britain, Conn, a corporation of Connecticut Application January 25, 1935, Serial No. 3,516 12 Claims. (01. 45-31) This invention relates to construction toys of the type having a plurality of. plate elements adapted to be interchangeably assembled in edge to edge relation and secured together by pins or the like and providing the opportunity of building structures of indefinite varieties and designs such as, for example, bridges, boats, automobiles,

etc. a l

The aim of the present invention is to provide ina construction toy of this sort an improved;

novel, andsimple arrangement for driving assembled toys (such as vehicles) or operating parts thereof (such as the boom of a crane, the

leaves of drawbridges, etc.) I

More particularly, an aim of the invention is to provide an improved driving arrangement which is characterized by its extreme simplicity and cheapness in construction, the ease with which the parts of the unit may be assembled, and the facility with which the driving mechanism may be controlled so as to operate at any desired speed and in the desired direction.

A further particular aim of the invention is to provide an improved arrangement wherein the driving elements may be suitably supported by the plates of which the toy may be in part formed.

Other objects will be in part obvious, and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawings wherein is shown for illustrative purposes several applications of my improved arrangement.

Fig. 1 is a perspective view of aportion of a drawbridge in which my improvements are incorporated; e e V Fig. 2 is a side view of a vehicle in which'is incorporated my improved motor unit;

Fig. 3 is a side view of the assembledmotor unit; 4 V V Fig. 4 is a horizontal sectional view of the unit on a larger scale; and 1 Fig. 5 is a detail view in section through the driving mechanism, this view being taken substantially 'on line 5-5 of Fig. 4.

Referring to the drawings in detail, I have shown the toys as comprising a plurality of metal plates l0 each having a flat form of polygonal shape and each provided on each of its edges with a plurality of spaced apart knuckles H prefv erably offset out of the plane of'the plate. The

dimensions of the plates and the arrangement of the knuckles are such that the plates may be interchangeably and universally assembled edge to edge with the knuckles thereof in intervening relation. The plates are preferably formed of metal by stamping out a blank of desired configuration with projecting ears, and then curling the ears into the form of cylinders. The plates are held in assembled relation by pins IZ extending through the aligned ears.

In Fig. l, I have shown these plates as being assembled to form a portion of a drawbridge having a suitable pivoted leaf I5 and. towers It. In Fig. 2 I have shown the plates as forming a vehicle l1. 'It will be understood, of course, that these disclosures are by way of illustration only, as obviously my improved driving mechanism may be used in connection with other structures.

In accordance with the present invention, I provide a driving arrangement the parts of which are supported by a box made up of the interchangeable plates which form parts of the assembled toy. This box may include an .end wall 20 made up of two plates 28 constructed similarly to to the other plates and adapted to be interchangeably and universally matched and assembled therewith. In the present illustrative disclosure, these plates 20 are positioned back to back to provide two sets of spaced knuckles, one set of knuckles 2! being offset to one side and the other set 22 of the other side so that the end Wall may beused as a partition. Secured by the pins l2 to opposite side edges of the end wall 20 are side plates 24 which are similar to the other plates of the toy in that they are provided with knuckles similarly positioned and they are adapted to be interchangeably matched with any of the other plates. The plates 24 may be maintained-in parallelposition and at right angles to the plane of the end wall 28 by a top plate 25 of the same construction as the side plates and having its knuckles at its respective edges intervening with the knuckles on the top edges of the side plates and one of the plates 20'. The top plate is held in place by the pins l2 passing through theregistering knuckles. Obviously, if desired, the box may have a bottom and a top plate. .In the event that it is desired to operate or drive a part of the toy through a jackshaft,

' the arrangement shown in Figs. 3 and 4 may be used. In this case, the supporting box may include additional side plates 26 connected to the edges of the plates 24 and an end plate 21 between the rear edges of the plates 26 and also an additional top plate 28, all of these plates being of the same construction and arrangement as the plates employed for making the toy.

The driving mechanism preferably includes a small electric motor secured to, so as to be carried by, the end wall 20. In the present instance, the motor is secured to this wall by screws 3|, and the plates have a central hole for accommodating the boss on the adjacent end of the motor casing. The motor shaft is indicated by the numeral 33. Mounted on this shaft, as hereinafter described more in detail, is a friction drive disk 35. The side plates 24 are provided with aligned and centrally disposed apertures 36 which more or less closely and slidably receive a shifting rod 31 which extends transversely through the box. Rotatably mounted upon, but held against axial movement relative to, the rod 31 is a sleeve 38 having a grooved portion 39 which forms a pulley. Carried by this sleeve is a leather wheel 40 the periphery of which is adapted to engage the face of the disk 35.

For the purpose of holding the rod in any longitudinal position of adjustment, a very simple and economical arrangement is provided. To this end, the rod 31, which is resilient, has one end turned back upon itself so as to provide a U- shaped handle 4|, and the short arm 42 of the handle is engaged in an aperture 43' in one of the side plates 24. This aperture is so located relative to the aperture 36 of that plate that the distance therebetween is less than the distance between the main length of the rod and the free end of the arm 42 when the latter is not engaged in the aperture 43', as shown most clearly by broken lines in Fig. 4. With this arrangement, when the arm 42 is engaged in the aperture 43', the handle is placed under compression so that the main portion of the rod and the arm 42 thereof will be pressed against and frictionally engage the edges of the apertures 36 and 43', respectively, Thus the rod will be frictionally held in any position of adjustment. The speed and the direction of rotation of the driven member will depend, of course, upon the position of the wheel with respect to the axis of the driving member 35. When the wheel engages the face of that driving member adjacent the periphery of the latter, the wheel is rotated at maximum speed, and as the wheel approaches the center of the disk, the speed is gradually reduced until when the wheel engages the exact center of the disk no rotation will be imparted to the wheel. When it is desired to reverse the direction of rotation of the drive member, it is merely necessary to move the wheel from one side to the other side of the axis of rotation of the disk. Thus it will be seen that the speed of the driven member may be very nicely and easily controlled, and its direction of rotation may be changed at will.

By preference, the drive disk is resiliently urged into engagement with the periphery of the driven wheel 40 in order to avoid close tolerances, to take up wear, and to obtain the desired frictional driving engagement. In the present instance, there is provided a very simple, economical and effective arrangement wherein the spring 43 for urging the disk against the wheel, also serves the function of forming a driving connection between the motor shaft and the disk. As shown most clearly in Figs. 4 and 5, the shaft 33 has secured to it, as by means of a screw 44, a flanged collar 45, and the disk has a cylindrical collar or boss 46 which slidably receives the outer end of the motor shaft 33. The spring 43 is in the form of a coil into the opposite ends of which the collars 45 and 46 frictionally fit. With this arrangement, when the shaft 33 is rotated, the collar 45, due to its frictional engagement with the spring, will tend to wind up the spring, thereby causing the convolutions about the collar to securely grip the latter; likewise, the convolutions encircling the hub or boss 46 of the disk will grip that boss, and thus the disk will be driven.

The driven member, which includes the sleeve 38 and the Wheel 40, may be very simply and conveniently held against sliding movement relative to the rod 31 by providing grooves 41 in the rod and clips 43 engaging in these grooves. The clips are preferably made of spring wire cut to lengths and bent into U shape. The arms of the clip have humps 49 which form registering recesses adapted to receive the reduced portions formed by grooving the rod. The end portions of the arms are flared outwardly so as to facilitate positiomng of the clips.

In the embodiment shown in Figs. 1, 3, and 4, the part to be operated, in the present instance the leaf of the drawbridge, is operated through a jackshaft 50 which is journaled in centrally disposed apertures 5| provided in the side plates 26 of the supporting box. Secured to this jackshaft and located Within the box is a pulley 52 having a hub 53 fixed to the jackshaft as by a set screw 54. A belt in the form of an endless string 55 passes about the pulleys 39 and 52 so that rotation of the wheel is imparted to the jackshaft. The string 56 (or strings) which represent a cable associated with the part to be operated is connected to the jackshaft so as to be wound upthereon and played off therefrom as the same is rotated. In the embodiment shown in Fig. 1, two such cables are illustrated.

In the embodiment shown in Fig. 2, my improved arrangements are shown incorporated in a vehicle. In this case, the motorized unit forms a part of the body of the vehicle. The rear axle of the vehicle is provided with a pulley 60 about which passes the belt 55, the jackshaft in this instance being omitted.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
