KNOGKDOWN TOY Filed June 14, 1946 1 INVENTOR.

Lou/s eya/ Y ATTORNEY- Patented Nov. 12, 1946 UNITED STATES- PATENT OFFICE KNOCKDOWN TOY Louis Segal, New York, N. Y. Application June 14, 1946, Serial No. 676,6774 'i 18 Claims.

This invention has to do with knockdown and erector toys especially adapted for convenient assembly of miniature structures to simulate automotive vehicles and certain types of buildings, bridges, .and parts thereof although other structures than those referred to may be constructed with the invention herein disclosed. The invention has as an important object the provision of a support having spaced clamping members embodying arcuate track means removably and slidably kdisposed in arcuately alined slots of laterally extending wings of complementary depending sectionsadapted to removably clamp rod or brace means insertible in guide means common to and bridging the complementary sections. The invention has as a further object the provision of spaced clamping means for arcuately and slidably guiding a rod holder or nipple of relatively thin sheet metal stock adapted to be progressively and automatically formed in a conventional punch press. Another object is to provide a simplied nipple or rod holder which may be quickly formed and produced in large quantities at a relatively low cost. Another object resides in the provision of a split bushing or bearing for positioning the spaced clamping members for the nipple or rod holder a predetermined distance apart and for appropriately clamping a shaft against dislodgement relative to the spaced clamping members. Another object is realized in the provision of means for actuating the spaced clamping members to tighten or loosen the latter against or from the split bushing and against or from the laterally extending wings of the nipple. Another object is to maintain the spaced clamping members which may be in the form of partial discs or segments in yieldable engagement with the winged and complementary sections of the rod or brace sustaining nipple when the latter is in an unclamped relation with the spaced segments. Another object is to provide a one piece sheet metal nipple having annular guide means for receiving a rod or a brace to be clamped and having depending complementa-ry sections carried by and depending from the annular guide means for straddling and removably embracing the rod or brace inserted into the guide means, the complementary sections being provided with notched wings adapted to be actuated to lmove the sections towards each other to removably clamp or embrace these sections against the rod or brace. Specifically another object of the invention is concerned with a serviceable nipple wherein the head thereof is characterized by an annular guard or guide and depending and inwardly offset and resilient limbs, and wherein the lower portion of the nipple is characterized by companion or complementary contiguously disposed but separable rectilinear and tapered sides having laterally extending and spaced wings provided with spaced slots disposed on an imaginary arc having a common origin for receiving spaced arcuate track means or flanges of spaced segments orsupporting members for movably guiding arcuate displacement of the nipple about the spaced segments. Other objects, advantages, and functional and structural features of the invention will appear from the following detailed specification taken with the accompanying drawing wherein: v

Illustrative of the embodiment disclosed, connectors each generally denoted C adjustably sustain nipples or holders each broadly designated N adapted to removably clamp and support the tie rods or braces I@ against removal.

Each nipple or holder N embodies an annular guard or guide Il from which depends the separable complementary sections comprising the diametrically disposed arms or limbs VI2 having the inwardly and downwardly projecting or offset portions I3. Also forming a part of the comp-ementary sections I9 are the substantially trapezoidal and downwardly converging sides- S each having spaced and inclined or biased but laterally extending anges or wings W each interrupted by a notch or slot I4, these wings being normal to the plane of the rectilinear portions of the complementary clamping sides. Each side S of a nipple or holder N comprises an arcuate or substantially semi-circular bearing portion I6 each having at its bottom portion an inwardly turned lip or stop Il.

The complementary clamping sides S are rectilinear but are interrupted by the semi-circular bearing portions I6 each characterizing an internally arranged groove i5 and the latter in fact may be said to constitute a bore for closely receiving a rod or brace IIJ. The annulus or guide, Il,

3 the depending offset limbs I2 and the depending sides S are formed out of a single piece of sheet material. For purposes of specification the head of a nipple may be said t be formed by the annulus or guard I I and its depending and offset resilient limbs I2. The inside rectilinear faces of the companion sides S are normally disposed in juxtaposition and are separated or diverged from each other upon the insertion of a rod I0 into the complementary bearing portions I6 or in other words in the bore defined by the grooves I 6', and of course this bore is in alinement with opening I8 of the ring or annulus I I. Thus a rod Il! if inserted into the spaced sides S of the complementary sections I9 spread the nipple that is the sides S thereof and if removed from the latter the resilient limbs I2 automatically retract the complementary sections I9 to again arrange the sides S in close juxtaposition. If rod I0 be inserted into the guide opening I8 of the guard or annulus II and into the complementary grooves I6', eventually the diametrically alined lips or stops I1 limit such insertion.

Spaced segments or members 2D and 2l characterize a supportfor a rod holder or nipple N. As illustrated, the segments are partial discs each having a substantially semi-circular portion 22 having an inwardly overhanging circumferentially disposed or semi-annular flange or track 23 adapted to be removably receivable in the alined slots or notches I 4 in the spaced and sloping wings W of the tapered or complementary sides S. The guide notches or slots I4 of each wing W are along an imaginary arcor circumference equidistant from the origin of the latter. Consequently a nipple N may be arcuately and slidably displaced along the spaced guides or track means 23 or the latter may be slidably and arcuately shifted relative to the nipple.

For normally holding a pair of companion segments 20 and 2l in a predetermined spaced relation, a split sleeve or bearing generally denoted 24 is employed. This bearing or bushing 24 is characterized by complementary semi-cylindrical hollow bearing portions 25 provided with reduced and hollow semi-annular ends 26 for closely receiving a shaft 21. Apart from the end portions 26 the remaining portions of the split and cylindrical bushing 24 is enlarged or expanded and is appreciably spaced from but surrounding shaft 21 although its intermediate portion is desirably indented to provide an annular groove 28` in which the split annular and resilient wire or spring 29 is disposed for normally holding the complementary bearing portions or sections 25 yieldingly together. With the rod or shaft 21 inserted inthe split sleeve or bushing 24, the bearing sections 25 thereof are slightly separated against the resistance of the split wire retaining ring 29. However the reduced ends or necks 26 of the sections 25 appropriately clamp the inserted shaft 21.

The ends 30 of the intermediate and expanded portions of sections 25 are rounded and tapered, converging outwardly and characterize stop means for the tapered hubs or annular sockets 3| integral with and overhanging the outer faces of the segments 20 and 2l For effectively maintaining sockets 3I against the tapered ends 30 of the expandible and contractible bushing 24 to sustain the flanges or tracks 23 a predetermined distance apart, clamping means comprising a bolt and nut arrangement broadly designated 32 (Fig. 9) is employed. It will be observed that annular collars or necks 33 arestruck out of the segments or sustaining plates 4 20 and 2 I. These collars slidably receive the partly threaded shank 34.

Surrounding one of the necks 33 and effectively positioned thereby is a normally expanded helicoidal spring 35 which also surrounds a part of shank 34. 'Ihe ends of spring 35 abut the slotted head 36 integral with shank 34 and neck 33 of the sustaining or segmental plate 20. By manipulating the internally threaded nut 31 cooperating with annular neck 33 projecting from the segment or plate 2U, the inwardly overhanging tracks 23 may be securely clamped in the circumferentially alined slots or notches I4 against the wings W, thus precluding their displacement relative to the segments 20 and 2I. By such clampaction the complementary sections I9 of a nipple N are urged towards each other, thus causing the complementary bearing portions I6 thereof to firmly bind or clamp against the rod or brace I0. On tightening of nut 31, the complementary bearing sections 26 more firmly clamp the rod or shaft 21, thus precluding accidental dislodgement thereof from the connector C and more particularly from the spaced segments or members 20 and 2I. On loosening nut 31, nipples N may be slidably displaced along the circumferential tracks or flanges 23 and if desired they may be completely removed from the connector or the spaced segments 20 and 2| may be slidably displaced relative to the nipple for a similar purpose. On such loosening, however, the complementary bearings I6 unclamp rod or brace I0 and consequently the latter may be removed from the unclamped nipple N. Where the nut 31 is loosened but the rod is not removed from the unclamped nipple, the latter of course may be shifted arcuately along the connector and at such time helicoidal spring 25 yieldingly bears against one of the segments or supports and consequently the complementary or companion section maintain their yieldable engagement with the loosened nipple. It is apparent that on tightening of nut 31, a dual function arises, namely, the brace or rod I9 is clamped against removal and shaft 21 is precluded from being Withdrawn from I ent therein.
