Toall whom it my concerns Be it known that I, Fnmonron Anew Rrcn'rnn, a sub'ect of the German Emperor, andresident 0 Rudolst'adt, Germany, have useful Improvementsin .Toy Bridges. of which; the following is a s 'ecification;

My 'inventlon relates to toybridges and has for its object to provide a bridge composed of several parts which may be readily assembled andput together in a simple manner without the aid of screws, splints, pegs m invention,=Fig. 3 is asimilar view of view of a bridge section ,'and Figs struction shown in still another form, Fig. 4. is a perspective 5 and 6 are perspective views of two additional forms of my invention.

In the drawin s a represents preferably U-shaged bows o angular cross section arrange as to form substantially a foundation on which the bridge isconstructed and supported. In the lparticular forin of conig. 1, the bridge girders c are formed with angular flanges which ex:

tend. lengthwise thereof at opposite edges and each of which is provided with an aperture located nearits' opposite ends it being understood that the apertures p of each flange at each end, are" m alinement with each other." These apertures 2 are of a size and shape to be readily slipped over the upwardly extendingmembers of the how a, as clearly shown 1n Fig.1. "Each of said, 'rders-c is further provided near its oppos1te'ends with lugs engageithe upwardly extending members of thebows a, when the parts are assembled and revent accidental displacement thereof. bridge section 0 is supported on the horizontal members of the bows a. in the finished structure. 'To assemble this form a of bridge the of the girders be connected and asv be had to the accompanyb v 'the girders 0 are slip improved bridge construction,

said girders may be the lugs q or supporting "said g which fr'ictionally -tion on' the bows the bows a and the bri ge section '0 is set u on he honzontal portion of said bows a. T e' apertures p cooperating with the up.--'

'ght members of the bows prevent any ative a vertical one.

are slipped over the 'right me'iilbers of} movement of the girders other than In the f rm of my invention shown Fig. 2,'each bow a is provided with resilient members I) suitably secured .in' position thereon and extending parallel with and a'd jacent to the upright members of said bow.

In this illustration, the girders c are formed with flanges similar to the longitudinal flanges on the girders shown in Fi 1, with the exception t at said flanges in ig. 2 ter minate short of the ends of said irders.

The said girders further have their endspre'ferably turned or bent to form-vertical flanges f, which,

In assemblingthisform of my invention,

ed bet-weenthe right members on the ws a and the resilit with the horizontal flanges hereinbefore referred to, form recesses --e'.

ent members b in, which position they are firmly held a ainst displacement by the pressure of'sai resilient members. Lengthwise movement of said girders c, is prevented through the medium of the flange fund the horizontal flanges'which engage'opposite edges of. the upright -members of the.

bowsa. In, other words the said upright members extend between the flanges f and the ends of the respective horizontal flanges into the recesses e and secure the said g1r-' ders in position. In. this form'the bridge section 0 maybe supported directly on the horizontal members of'the bows a which in this caseare' provided with a reinforcing piece as shown in Fig.-

rovided with lugs similar to bridge section'o. r

In Fig. 3 the girders c' are constructed in thesaine manner as the girders c in Fig. 2 and are secured 'to the bows'a. by means 0 A similar'resilient devices b.-' The bows a in 2', or if desired; the

this form, however, are made with upright members of increased len h and are-,pro-

vided with additional resi ient holding devices b for the accommodation of railings d. The said railings are secured in ime'mbersb' and the uprightmembers of the.

between the res: ientbows a and set upon theupper edgeof the t of these girders c'. Lengthwise movem tier railings is also prevented by means of es words the recesses e, in the same manner as described with regard to the girders 0 in Fig.

the girders '0 near the upper edges necessary thereof and serve to support the bridge sec tion 0. i

The construction shown in Fig. 5 differs from those already described inv that the u pr ght members of the bows a are provided with spaced projections g which cooperate been substituted for the projections g of Fig. 5 and slots is have been substituted for he slots 2', otherwise this form of my invenion is-the same as thegt shown m Fig. 5.

In Fig. 5 the girders and'reilings are prevented from slippin from the projections c v by means of the heads thereof, the shanks of said projections extending through the reduced portions 1 6 the upwardly of said slots, while in Fig. extendi. 5 portions of the such di p :icement of the girders and railin s. it is to be understood that-the heads of the pro-' 'ections c are of size to easily slipped through theenlarged pins h prevent portions of. the slots i but are too large to pass throughthe reduced portion thereof. films to said rders it is first to raise 1 to ing the enlarged portions ofthe slots 11 and the heads of the lugs lo into registry with each other sitter t willthus be that in the forms of my invention, the scverelpar'ts constituting the finished, structure, are all easily and f and horizontal flanges or in other 2. Pins or projections m are located.

3 tending flanges at opposite edges.

flanges terminate short of the ends of the lich said girders may be removed by a smple lateral movement.

quickly assembled without the aid of screws i or other similar fastening devices,'and when so assembled, are firmly held in position against accidental displacement or dislocation. ,In order to prevent the bridge section 0 from slipping from the-various supporting mediums, that isthe lugs g and projections m and n the said bridge section 0 is formed with longitudinal downwardlyex- These bridge section 0 and the ends thereof abut against the said lugs g and projections m I and n so that lengthwise movement of the bridge section 0 is absolutely prevented.

' Variousfchanges the specific constructlonsshown and described may be made.

withinthe scope of the volaims without departing from the spirit of my invention.

I claim:

1. A toybridge comprising supporting end members, removable side members slidably mounted thereon and a bridge section removably connected therewith. I

2. A toy bridge comprising U-shaped end. members, removable sidemembers slidably mounted on the upright portion of said end members and a bridge section removably connected therewith.

3. A toy bridge comprising side members provided with openings, U-shaped' end mem bers adapted to extend into said openings and a bridge section connected with said end members. y

4. A to'y'bridge comprising side members,

flanges extending lengthwiseof-said side members and each. rovided with openings,

U-shaped end mem ers ,sdapted to extend into seid openings, projections on said side members adapted to frictionallyengage said end members and a bridge section removably connect-ed with sai-d endmembers,
