I nUILDING-BLOCK.

To all whom it may concern Be it known that I, IVILLIAM F. 'HAsKiNs,

a citizenof the United States, residing at San Francisco, in the county of San Francisco and State of California, haveinvented new and useful Improvements in Building- Blocks, of which thefollowing is a specifi In the accompanying drawing, Figure 1 is a perspective view of one of my improved building blocks; Figs. 2, 3, land 5 are similar views of other blocks of difierent forms;

ture made by my improved building blocks. Referring to the drawing, 1 indicatesatoy building block formed of wood, and which,

7 to distinguish itfrom other building blocks hereinafter described, I term a tie-bar, since it is generally, although not necessarily, used structure. In form it is rectangular and comparatively thin,and varies in length,'and has a mortise 2 in its edge extending entirely around it. r

V 3- indicates a block of another style, which, because of its general use as .a supporting member, I term a post-block. In cross-section it is of a general rectangular form, but from the center of each of the four, sides .4 of the rectangular projects outwardly a tenon 6 of a thickness to fit snugly in the mortise 2 in the tie-bar 1, either at its. sides or at itsends, a little pressure being required to force it into the mortise, so that, when forced in the tie-bar, it is supported upon the post-block by the friction between its flanged portions, extending beyond themortise, and the sides of the tenon 6 of the postblock. The mortises at the ends of the tiebar are each of depth such that a tenon of the post-block can be pressed into the mortise to its full depth and so that the edges of the flanges of the tie-bar abut against the sides 4 of said post-block.

7 indicates a block of a third style, which, to distinguish it from the others, I term a dowel-block. The dowel-block is simply a piece f Wo d o sq a e cross-section and r to other post-blocks. middle portion of the bridge are connected f f Specification of teti i sratena i aitentedAug lfl 1 915. Application filed April 20, 1915. Serial No. 22,584.

V i the same thickness as the tenons of the postblock.

The above-describedblocks, of different sizes, constitute the main elements of a complete set of toy building blocks, as they 00- operate with each other in a novel manner, but I also provide auxiliary blocks such as the plank block 8, shown in Fig. 4-, which is in the form of an ordinary plank or board, and the finishing block 10 shown in Fig. 5, which is a rectangular block of wood with a wedge-shaped recess at one end, used for representing chimneys in toy building structures, or for other purposes, as may be found convenient. v r

In Fig. 6 is illustrated a bridge constructed of my improved building blocks. It will be seen that two post-blocks 3 are placed horizontally on the ground to represent supports for the bridge, and on these are erected post-blocks, to which are connected, in the manner above-described, ends of tie-bars, the other ends of said tie-bars being connected The posbblocks in the to each other by tie -bars and on three tiebars in the middle of the bridge are supported dowel-blocks, which in turn support tie-bars narrower than thefirst-named, the ends of which are connected in the usual manner to post-blocks of greater or less height. The upper ends of the latter are connected to one another and to the upper ends of the outermost post-blocks by tie-bars some of which are sloping. The post-blocks on opposite sides of the bridge are connected in the usual manner to tie-bars which form supports for planl blocks, constituting the roadway of the'bridge. y 7

The above is only. one of many different ways in which the blocks can be used.

I claim 1. In combination with thin tie-bars, each having a mortise in its edge entirely around its periphery, postblocks each rectangular in cross section and having projecting outwardly from the center of each of its sides a tenon, of the proper thickness to fit in the mortise of each tie-bar just sufficiently tight to firmly support either member upon the other by the friction between the co-engaging parts.

2. In combination with thin tie-bars, each having a mortise in its edge entirely around,

its periphery; post blocks each rectangular in cross section and having projecting outwardly from the center of each of its sides a tenon, of the proper thickness to fit in the mortise of each tie-bar just sufiiciently tight of a piece of wood of square cross section Witnesses.

and of like thickness withthe tenonof each 10 post-block.

In testimony whereof I have hereunto set my hand in the presence of two subscribing WILLIAM "F. HASKINS. Witnesses: o

FRANCIS M. VRIGHT; D. B. RICHARDS.
