TO THE A. C. GILBERT COMPANY, OF NEW HAVFN, CONNECTICUT, A. CORPORATION OF MARYLAND TOY BUILDING CONSTRUCTION Application filed February 23, 1927. Serial No. 170,259.

This invention relates to toy building construction, and more particularly to toy con- .struction of fairly light sheet metal which simulates in appearance the modern struc- B tural steel used in building bridges, skyscrapers, towers, cranes and the like. Furthermore, my invention pertains especially to toy building construction which can be used to build various models where a hollow box column or girder simulating a commercial lattice girder is required.

()ne of the primary objects of my invention is to provide an improved form of strip which is adapted to be combined with a plurality of like strips in such'a manner that a very close simulation of box girders, angle beams and other shapes and structures used in commercial steel work may be readily obtained. v Another object of this invention is to provide an improved form of strip or toy building element, which is adapted to be joined lengthwise to another similar one to form an extension thereof, and whereby an extended element may readily be provided of various lengths, as required by the toy model to be constructed.

Still another object of this invention is to provide an improved form of toy building element which is adapted to be associated with another element of similar form, whereby a sturdy, rigid angle piece or beam may readily be formed for use in various toy models.

Still another object of the invention is to furnish an improved construction of hollow box girder or column.

To these and other ends the invention con sists in the novel features and combinations of parts to be hereinafter described and claimed.

The building element shown in detall in Figs. 1, 2 and 3, is constituted by a strip of sheet metal comprising a body portion 10, and a side flange portion 11. The flan e 11 is provided with perforations 12, whic are equally spaced apartlengthwise of the same and intermediate the strip ends. An additional perforation 13 is provided at each end. Each .of the perforations 13 is preferably spaced from the adjacent end an amount substantially equal to the amount it is spaced from the edges of the flange 11, and further, is in alignment with and spaced from the adjacent perforation12 an amount substantially equal to one-half the distance between any two of the perforations 12. The perforations 12 and 13 are preferably elongated transversely of the flange 11, and with respect to the strip, for a purpose which will be hereinafter described.

The body portion is provided with a plurality of series of aligned perforations 14, e ually s aced apart lengthwise thereof and ispose one series alon each edge of the body 10. Additional per orations are provided in alignment with and spaced from the perforations 14, in the ends of the body 10, in a manner similar to that of the promsion of the perforations 13 in the flange 11. The perforations 14 and 15 in the body 10 correspond in spacing to the perforations 12 and 13 in the flange 11, and are in alignment therewith transversely with respect to the strip. The perforations 15 provided in the body 10 are preferably. elongated transversely thereof.

Spaced from each edge an amount substantially equal to the width of the flange 11, the

. body 10 is offset out of the plane thereof by being bent inwardly in the direction taken by t e flange 11. This forms an offset portion 16. The portion 16, in this instance, is cut awayat 17 and 18 to form cross bars 19 and 20, which intersect along the medial line of the body 10. At each of the intersecting points of the bars 19 and 20., the body is provided with a perforation 21. The perforations 21 are in alignment and are spaced apart an amount equal to substantially twice the amount of the spacing between the perforations 12 and 14, and correspond to every other one of the same. An additional perforation 22 in alignment with the series of perforations 21, is provided at each end of the strip, and corresponds with the perforations 13 and 15 of the flange and body respectively, being in alignment therewith transversel with respect to the strip.

The angle piece or beam shown in Figs. 4, 5 and 6, is constructed by the use of two of the elements, as above described. These elements are arranged with the end edge 23 of one abutting against the flan e 11 at the end of the other element, with both flanges outermost and extending in the same direction. Fastening means, such as bolts 24, pass through registering perforations 14 and 15 of these elements. An especially rigid and sturdy structure is thus formed, which will resist lateral bending and twisting or other distortion due partly to the reinforcing action of the flange 11 upon the body 10. partly to the bracing action due to abutting the end of one element against the flange of the other, and partly due to the stiffening action of the offset portion 16.

The box-like girders or columns shown in Figs. 9, 10, 14, 15 and 16, are composed of four elements formed as above described. In these figures, two of the strips or elements are disposed in opposed relation, with the flange 11 of each directed toward the unflanged edge 25 of the body 10 of the other element. By this arrangement, the flanges 11 of each are diagonally opposed. Another pair of strips dis osed in like position with respect to each ot er, are arranged in respect to the first two strips in such a manner that the unflangled edge of one stri overlaps the flange of t e adjacent strip. n Figs. 9 and 10, the unflanged edge 25 of each strip over-,

laps the flange 11 on the interior surface,

Securing 13 in the flange 11 of one strip, permits these perforations to register with perforations of the unflanged portions 25 of another strip. This feature also permits the lateral expansion of a box girder section, formed as above described, whereby another girder section may be secured thereto at an end thereof by interposing a similarly formed one in between the members of the elements of the first, as shown in Figs. 14 and 16. As either end of the girder may be expanded independently of the other a long extended girder may be constructed by joining together a pluralit of girder sections, formed as above describe which due to the light gauge of the material used, will still maintain an apparent symmetry of form.

An elongated girder constructed of aplurality of sections as above described, will be of particularly rigid construction, due to the cooperation of the flan e 11 of each element or strip with the edge of the other strip which it engages. Due to the rigidity of each strip, occasioned by the effect of the flange 11 being at an angle to the bod 10 thereof, no substan tial overlapping of t e girder sections is required. It is only necessary to overlap the end of one section over the end of the other an amount suflicient to register the perforations 13 in the flange 11 with the perforations 15 in the body 10. No additional plates or other parts are required to insure a rigid joint between the sections, when elements or strips of the above form are used.

- Figs. 7, 11, 12 and 13 show four different arrangements which are possible when it is desired to use one strip to form an extension of another, and to thereby construct an elongated element or strip. In Figs. 7 and 11 the elements or strips are overlapped with the flange 11 of each at the same side and directed in the same direction, with bolts 24 passing through registering perforations 14, in Fig. 11 the cross bars 19 and 20 of each strip registering, due to the use of certain of perforations 14 in each strip. In Figs. 12 and 13, the bolts 24 ss through perforations 14 of one strip, an perforations 15 of another. By proper arrangement of the strips and the use of certain perforations, an extended strip of be only limited in that no variation in length may be obtained smaller than the spacing between the perforations 14 and 15 of these strips,

From the above, it will be seen that the provision of a toy building element or strip, constructed'according to the above description,

)ermits the joining of one strip to a part havlhg equally spaced and similarly arranged perforations to form a variety of structures. It will be further noted that the structures formed will be of rigid construction, while being composed of a minimum number of prarts, due to the form of the element used.

arious changes may be made in the details of the construction without departing from the spirit of the invention 'and the scope of the appended claims.
