Application med June ao,

To all whom t may concern:

Be it known that I, SYDNEY A. METCALFE, a subject of the King of Great Britain, residing at Chicago,iin the county of Cook and State of Illinois, have invented certain new and useful Improvements yin Toy Building Constructions, of which the following is -a specification. i

My inventionv relates to toy building constructions and has for one of its objects the provision of simple andvellicient blocks and vsary in making toy buildings, and other toys. f-

Other objects will appear hereinafter'.v I

An embodiment of my invention is 4illustrated in the accompanying drawings, forming a part of this specification, and in which- ,f Fig. 1 is a view of a building constructed with my improved blocks and sheets;

Fig.- 2 is a constructionl of a building with mv improved blocks and'sheets with one side of each room open so that access may be obtained to each yof. the rooms of the building;

Fig. 3 is a block shown in perspective em bodving my invention;

Fig.l 4 is a view similar to Fig. `3, but-'showv ing fewer slots in the block;

Fig. 5 lis a piece of sheet material used for trimming around the top of the build. mg;

Fig. 6 is a view of a sheet of material used for making the walls, iioors and roof of the building;

Fig. 7 is a piece of sheet material used for making the foundation of the building; and

Fig. 8 is a view similar to Fig. 6. but showing notches formed in its' edges intermediate its corners.

Referring more particularly to the drawings, I haveindicated in Fig. 3 a block 9, such as I prefer to use. This block is approximately sona-re in transverse section and substantially twice as long as wide. In each end I preferably form two slots 10 and 11 at right angles to each other, whichA 1921. serial No. 481,458.

maybe saw-kerfs, and p'referablyfof depths equal to onesfourth the llength oiffthe block; It will be apparent that the depth of 'these cuts may be altered in accordance withthe utches of the sheet "material to be' described aer. Y yIn Fig. 4 Il have shown the-block 9 as having slots 10 only, and in this construction the eXtra labor' requiredto cut the slots 11 will be saved. In some parts `of i the slotsll will not benecessary. f

In' Fig. 6 I have-indicated azsubstantially square piece of sheet material having indications thereon representing window and wallconstructions. j It willgbe apparent that the indications on the wallv may represent any part of the building it isv desired `to build. At vthe corners yofthe 'sheet 12 I4 have formed notches/13, and each of the notches is substantiallyl as wide and high as the depth of slot l0.

Speccaton ofALetters Patent. i Pgtenfed 15,1922". i

the building In Fig. 5 I have` indicateda narrow strip i '14 of sheet material having twor notches 13 in its lower edge and these notches 'are ot substantially the same shape and sizeas the y notches 13 in sheet 12. When the parts 12 and 14 are arrangedy in abuildinga block 9 will fit intoadjacent'nOtChes 13,`as clearly indicated in Figs. 1 and 2, and'hold the adjacent edges of sheets 12 and 14 tightly ltogether. It is intended that the slots 10 and 11 should have widths so as to'trictionally engage the sheets 12 and 14l to hold the building together and be easilytaken` 4apart when so desired. l

In Fig. 7 VI have indicated a narrow sheet of material 15 wider than sheet 14, but it will be Iapparent that the widths of sheets 14 and 15 may bev varied as desired. The

- Vsheet 15 also has the notchesl?) in certain of its corners, 'suc'has the two upper corners indicated. and thesev notches 13 are also of similarsize to the notches 13 in sheet 12 so that blocks 9 can hold sheet 15 to the under edge ofsheet 12 and so that the adjacent edges kthereof will be substantially together. Where a building construction is to be of one story each side can have a foundation sheet 15, one wall sheet 12, and one trimming sheet 14 to make its height. Where the building is to be more than one story high then additional sheets 12 willk sheets 12, 14 and 15 when so desired so that they can be used for different kind ofsides of a building.

In fitting a block to the sheets the portion of the block between the slots engages the edge portions of the sheets so that the notches must be suificiently large to permit are in the edges intermediate the corners,

the notches in the sheets,

as indicated at 17. In this form of sheet the notches 17 are of substantially the same depth as notches 13, but twice as long so that the slots of a block can engage the `edges of a sheet 16 at the ends of the notch 17 and the portion of the block between the slots engage said notch 17, as clearly indicated in said Fig. 2. With this construction the horizontal walls are held more firmly than with the `construction using sheet 12, as indicated in Fig. 1. However the same blocks are applicable to both constructions, the only diii'erence being in the position of l prefer to Vmake the sheets referred to of cardboard, but any desirable substance may be used.

Fromvthe above it will be apparent that buildings of-various sizes and shapes may be formed by using three sizes of sheets, such as indicated, and one form of block, it being understood 'that the form of Iblo'ck in Fig. '4 may be used some places, as clearly indicated iny Fig. 1, on account of its more economical construction.

l claim: i

1. A toy building construction comprising blocks substantially square `in transverse cross-section and ofsubstantially twice the length of their widths with slots in their ends, and rectangular' sheet material pieces havingnotches in their corners with the edges of said sheets adjacent said notches engaging said slots and held bysaid blocks in building formation.

2. A. toy building construction comprising blocks substantially square in transverse section and substantially twice as long as wide, each block having a slot in its end,

said blocks between said slotsbeing in -engagement with the notches of said sheets.

4l. A toy building construction comprising a plurality of relatively narrow sheets with notches in their upper corners, a plurality of square sheets having notches in all their corners, substantially inarrow sheets having notches in their lower corners, blocks having slots at right angles to each other in each end thereof, said slots engaging edge portions of two adjacent sheets, and two adjacent notches engaging 'each block between the slots of the latter.

A toy building construction comprising upright walls formed of a plurality of rectangular sheets with notches in their edges, and blocks having .slots in their ends with each slot substantially one-fourth the depth of the length? of its block and said blocks engaging said sheets adjacent the notches thereof to lockthe sheets in the form of a building.

6. A toy building construction comprising.

a wall having two'sheets of material in edge to edge relation with registering notches in adjacent edges, and afblock having a slot in each end, the distance between the remote sides of said notches being substantially the same as the vdistancehlaterally through said block.

In testimony whereof 1l have signed my name to this speciiication on this 27th day of June, A. D. 1921.
