ing diagonal braces37fand 38,'and Irfpro'vide` a special joint for connecting these diagonals to-the' upper end'of the post 35. Thi'sconstruction 3 includes two brackets, l39V and 40'Y comprisingvtwo superposed plates connected Y tothe upper end of the post "bya center p in 41 passing down through' aligning lopenings in the plates; this pinfits into the upper end of the tubularpost 35. The plates 39 and 40 are provided with integralsleeves' 42 at their edges and these sleeves receive lateral shanks 43, respectively, formed on the ends of the ldiagonal braces 37 and 38. The body of the diagonal brace 37 is of tubular type, its upper end receiving a shank or arm 44 that projects at right angles to the arm 43. If desired, such a diagonal brace can be made of a solid bar 38, as illustrated in Figure l, the upper end of which is provided with a sleeve 45, the upper end of which connects to an arm 46-similar to the arm 44; At the lower end of the post 35 the same type of joint is employed (see Figure 5).
This elemental joint is illustrated'in Fi ures 6 and 6a, although in Figure 6 te brackets are represented ina slightly different position with the sleeves located on opposite sides of a supporting post 47.
I shall now describe this'elemental joint illustrated in` Figure 6. This joint comprisestwo brackets 48 and 49, the body of each bracket being formed of a plate and each plate having an integral roll at its edge forming a sleeve 50. yEach of these sleeves has a gap 5l so that it constitutesV a split sleeve. In order to increase the gripping force of this sleeve on a shank or pin thrust into it, I prefer to form the metal of the middie of the sleeve with an inwardly pressed waist 52 of reduced internal diameter. `With this construction of the sleeve it will be evident that a shank 53 can be readily in-.` troduced into the enlarged mouth 'of' the sleeve at the end, but will become tight when the pin or shank 53 reaches the middle of the sleeve. If desired, the shank 53 can be covered with an inner metal split sleeve 54, so
that it would enable the shank to have ar good bearing in case it is necessary to rotate the member carrying the shank on the aXls of the shank. The bracket plate may be provided with a similar sleeveconstruction.
to that just described.
In order to enable these brackets to maintain any angular .position with respect to each other, one ofthe edges of one of the plates may be crimped toward the opposite plate and one of the plates may be formed with an integral-eyelet 56 which pivotallyA connects the platesy together but enables themy to be shifted on the aXis of their' connecting.
dle portion offset inwardly, as indicated at v 61, to form a' constricted `clamping point'in the sleeve into which the ends of the rods 60i can be forced so as to be clamped frictiontsht. .l My plate form bracket elements carrying a pivot hole and a'sleeveare useful for con structing theltruck `frame as illustrated in Figure 9, inwhichgure'62 illustrates one of the tubular axles of the truck; The truck wheel 68 is mounted ona pin 64V thrust friction-tightinto the end of the split tube 62 and the outer end of the Apin is provided with? a head 65 that seats against the outer side of a vertical, plate-form bracket 66, the lower end of said bracket plate having an integral sleeve 67 to clamp over horizontal split tube 68 that forms a longitudinal side frame bar of the truck. (See Figure 2.) The ends ofl these bars 68 are connected bysuitablecross bars 70 constructed with corner angles7l having legs received in the Open ends ofthe'.
tubular bars.
e A- bracket plate of the general 'type' described above may be used in va waypto enable rods to be inserted in the sleeves by a lateral movement and then locked in the sleeves by a slight rotation of the brackets: Thisis s accomplished by having the plates of an-gu'-` larform so that when rotated, the corner 73 will project across the sleeve (see Figure 5 in connection with Figure 13)'. Iny this type of construction just referred to the sleevev 74 is open on the side toward the opposite bracket plate (see Figure 13).

The joint element illustrated in Figure l5 is useful in constructing a wagon or a truck having a superstructure above the aXle. This is illustrated in Figure 10,- in which 82a indicates a joint having a vertical arm 83 and a horizontal arm 84, in the angle of rwhich a bar 85'is rigidy secured, the inner end of' said bar being received in the end oa tubu lar axle 86 and the vouter end carrying-Q av wheel 87. j j Y This` wheel means of a coillspring 88,the coilsof which yieldingly` clutch: the side vface offthe bar. @ne end ofthis coil may be providedwith a.
may be held on theV axle by 1:60 These swivel bracket plates ofthis typer` N substantially lateraly extension 89. In putting this keeper coily 88 in position it may be rotatedl bythe handle 89 in a directiontending O llllcoil; the coil. This will enable-they j@ coil to go on the bar in a substantially loose mannerfbutassoon as the handle is released thecoil will clasp the-bai.
' The swivelV bracket unit is also very useful in".constructing a tripod of the, typeillus? trated in Figure 17.' In this view 90 indicates abottoni bracket plate having an integral sleeve91 at one edge and connected by a swivelpin 92- to an intermediate bracket platev 93 having an integral sleeve 94 atv an edge.y The two sleeves 91 and 94 are disposed one of my swivel brackets, as'indicated atV n 102embodying a plate 103 with an integral j sleeve 104 at a vertical edge seated on the pin 92 and having a back plate with an integral sleeve 105v extending at right angles to the sleeve 104 and carrying a bar 106. The two bracket plates that form thisv swivel bracket are connected together on a horizontal pivot or swivel 107. V Y v In Figure .I illustrate the preferred construction for mounting the windlass drum 5.
This drum -is mounted ona horizontal threaded shaft 108, the threads ofvwhich receive a nut 109 that can clamp against the adjacenthead 110 of thedrum. This nut109 has ahandle 111 for rotating it. By tightening up on the nut 109 by means of the lhandle llluthe drum canbeheld more or less frictionftight lbetween vthe nut` and the headV 112 on the outerv end of the l.drum shaft. This will` enable the child to givey a yielding resistance to the rotation of the drum in using the cord or cable 113 that issupported by the boom and provided with a hook 114 for handling a load such as illustrated on the truck in'Figure 1./
It is understood that the embodimentof the invention described herein is only one ofthe many embodiments this invention may take, and I do not wish to be limited in the practice'of the invention, nor in the claims, 59; to the'particular embodiment set forth.
` I claim: Y
Lesa-eos yielding resistance to the rotation of the plates on their pivotalv axis.
2. In a knockdown structural toy, a jointY having a pair of superposed plates pivoted together on an axis at' right angles lto the plane of theA plates, each of said plates hav- VVing an integral sleeve formed at anedge thereof to receive a structural rod, said plates being angularingform, and said sleeves being offset away from the plane of the plates and having anopensidetoward the plane of thel plates tolenable a rod to be inserted in each sleeve by a lateral movement, said plates operating when rotated on thepivotal axis, to project over the open side of the sleeve and lock the rods in them.
3. In a knockdown structural toy,\a joint consisting of a .pair of superposed pivoted plates, each plate having an integralsplit sleeve formed at one edge thereof, a structural rod having a shank with a taperedV tip fitting into saidsleeve, and means on the piv.-y
etal` axis of theplates for attaching a rod to the same to extend at right angles vto the plane of the plates. Y
4. A joint for a knock-down structural toy having a pair of plates pivotally connected together, said platesV being superposed and lying substantially in the same plane andv each plate'rhaving an integralsleeveformed at its edge toreceive a rodA held between the sleeve and the opposite plate and pressed therebetween. 1 f- 5. A joint for a knock-down structural toy having a plate with an integral sleeve formed at one edge of the plate, said sleeve being offset fromY the plane of the plate and open on the side toward the Vplane ofthe plate and capable of being snapped over a rod by a lateral movement of the plateV and sleeve to-Yl ward the rod. y
6. A joint for a knock-down toy comprisingfa pair of superposed plates Vhaving. a sleeve pivotally connecting the same'and capable of receiving a central pin, said plates lying in a single plane at right angles to the aXis rofthe sleeve and having integral sleeves A formed at their edges to recelve a rod corresponding toffeach sleeve.
