UN TAT S PATENT OFFICE EVERETT ravine ROGERS, .13., or PROVIDENCE, nnonn ISLAND TOY BUILDING oonsr'mro'rroiv Application filed. April 22,

light metal tubing, such as aluminum.

. My invention includes hollow members preferably tubing preferably provided with an inwardly projecting groove therein and preferably provided with two diametrically .15 opposed grooves o f this'type. The grooves not only assist in binding the various parts of my invention togetherbut they also materiallystrengthen the tubing. I -providemeans to secure the pieces of tubing together .20 at anglesto eachiother preferably substan tially in the same plane comprising clip members each having a'split tubular headadapted to surround one pieceof tubing and attaching prongs projecting outwardly. from the edges of the split in said head having spaced lower portions of substantially hemitubular form registering-within an end of a second piece of tubing abutting an inwardly projecting groove thereof to secure said ..30 tubing to said clip against rotative movement thereon and preferably also inwardly inclined portions above said hemi-tubular portions. With this construction it is pos sible to secure the head of said clip member to the first piece of tubing andby sliding said first piece of tubing within until it is brought to the desired angle with'relation to the desired position of a second piece of 1 tubing and indenting a'portion of said head 40 within saidgroove to secure said head to said tubing against rotative movement thereon. Afterthe second piece of tubinghas been in serted over the prongs it is possible to burnish or turn overthe ends ofsaid second a5 piece of tubing over the inclined portions of 1930. Serial No. 446,371.

ing groove thereon, it, is obvious that said clip member is secured to said second piece of tubing against rotative movementtherein by said groove. Objects of my invention therefore are to provide a toy or model building construction including tubing and hollow members preferably clip members for attaching two pieces of said tubing together at angles to each other. With one type of clip the pieces of tubing are attached approximatelyat right angles to each other. If it is desired to attach said pieces of tubing at other than at right angles to each other the clip members are constructed so as to be piv otable. I also preferably construct the heads of the clip member so that when attached it will be'of slightly smaller periphery than that of thepiece of tubing embraced, thereby to additionally squeezesaid head around the tubing to bind it thereto and in attach ing the second piece of'tubing over the prongs to compress'them so that the expansive action of the prongs will function additionally piece of desired portions of the clip head within the tubing groove. While I preferably employ inwardly grooved round tubing, it is obvioils that the clip members and hollow members may be of any desired shape so as to prevent relative turning movement between the clips and hollow members.

These and such other objects of my invention as may hereinafter appear will be best understood from a description of the accompanying drawings, which illustrate various embodiments thereof employing inwardly grooved tubing.

.size together. In the embodiment shown in Figs. at, and 4 the head 24.- of the clip mem- -'ber is of alarger periphery than the pcriphery ofthe split prongs 26 to attach a smaller piece of tubing to a larger piece of tubing. In the embodiment shown in Figs.

5 and 5 the split head 24 of the clip member is of a smaller periphery than theiperiphery ofthe prongs 26 tl1ereof toattach a larger piece of-tubing to a smaller piece of tubing.

As shown in the drawings the pieces of

tubing

20 and 20" are preferably provided with inwardly projecting grooves 28, preferably two as-shown on diametrically oppositesides of said tubing for a purpose to be described. The clip member 22 is provided with the split tubular head :adapted to surround a piece of tubing-30 and attaching prongs projecting outwardly from theedges 32 of the 'splitportion of'saidhead having spaced lower portions 26 of substantially ihemi-tubular formand of a size to compactly'register within an end of asecond piece of 'tubmg '34 prefer-ably as-shown in Fig'lO between the inwardly projecting grooves 28 thereof to secure said tubing to said clip against rotative Said prongs are also preferably provlded for a purpose to be described with=the inwardly inclined portions 36 above said hemi-tubular portions 26.

=Figs.6'9 Show the steps necessary to attach the second piece of tubing 34 to the first piece of'tuhing 30. The'prongs 26 of the'clip 22 are split apart so that the clip '22 may be spread laterally so that the head 24 thereof may embrace-the first'piece of tubing 30 as shownin Fig. 6 afterwhic'h when the prongs are pinched together so as to compactly fit within the end 38 o'f-the second piece of tubing34. As shown inFig. 7-the end SS o'f said second piece of tubing '34 is placedopposite the prongs 26 and forced upwardly so that the prongs 26 may register within the end "39 of saidsecond piece of tubing preferablyhetween the grooves 28 thereof to secure said second piece of tubing against rotative movement on'said clip. To secure the head .24 of said clip -member 22 against rotative movement on saidfirst piece of tubing 30 portions 40 of the head thereof-are indented inwardly within-the groove'28. To'securethe second 'pieceoftubing 34 against longitudinal movement from said clip 22 the end portion 38 thereof is burnished over said inclined portions 32 as at 42 asshown in 'Fig. 9.

To make the action of the clip also a wedge action the split tubular head 24 of said clip is when the wedge prongs 26 are resiliently retained within said second piece of tubing;

The prongs 26 are also constructed to have a tendency to spread apart when inserted within the end 38, thus also resiliently tending to additionally bind said prongs 26 within said end 38 of said second piece of tubing34.

' In Figs. 13 and'14 I have shown a slightly different embodiment of my improved clip member including a pivotalportion in the prongs thereof. In this'embodiment the head 24 is provided with the flat extensions 44 pro- 1 jecting outwardly from the'edges 32 of thesplit in said head 24 and the prongs 26 are provided with an upwardly projecting flat portion 46 above the inclined portions 36 thereof insertable between the portions 44 projecting from said head 24 and pivotally attachable thereto by means of the pivot pin 48. Said head 24 and prongs 28 are pivotally attached together by said pivot pin so that when relatively tilted they will remain in a set position. This type of clip is employed when it is desired to attach the two pieces of tubing together at angles other than right angles for which the preferred type of clip shown in'Figs. 3-10 is employed.

It is also apparent that if desired the meme bers 30 and 34 may consist of hollow members of any configuration,preferably shaped so as to prevent the clip member fromiturning relative thereto, such as square, triangular, etc.,

and that as the shape of the hollow members are varied so must the shape of the clip members be correspondingly varied. It is apparent that the grooves 28 not only permit the locking action in a manner heretofore described, but that they also strengthen the tubing. I have shown in Fig. 1 an aeroplane fuselage built up of my improved pieces 7 of tubing and clip members. Relatively long pieces of tubing 50 may be employed for the longitudinal ribs of the fuselage and said" longitudinal ribs may be joined together by the horizontal and vertical cross struts 52. In making up the fuselage body it is obvious that the cross struts 52 will be attached to the longitudinal ribs at substantially right angles to each other and therefore that the clip members 22 shown in Figs. 39 may beemployed. The frame 54 for attaching the landing wheels thereto consists of V-shaped pieces of tubing depending from the lower longitudinal ribs and as it in this instance has the upper end of the V portion thereof attached to the lower longitudinal ribs50 at an angle the type of clip member 22' shown in Figs. 13 and 14 may be employed. The tubing and clip members may be constructed of any desired material, such as metal, celluloid, brassQ composition, etc, but in making model aeroplanes of a flying lightness I pref-- erably use the hollow aluminum. tubing shown and so far as I am-aware I am the first to provide an all metal toy aeroplane fuselage. I employthe word toy to include models of any sort, working models or otherwise.

It is thus obvious that I have provided a novel type of toy building construction which may be put together by a boy in relativeeasy fashion and which is particularly desirable for use in building toy aeroplane fuselages. It is understood that my invention is not limited to the specific embodiments shown and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.
