EDWARD S. SAVAGE, OF ROCHESTER, NEW YORK.

CHANGEABLE ASSEMBLY SET FOR AJKIUSEIVIENI AND EDUCATIONAL PURPOSES.

Application filed January 20, 1925.

My invention relates to that class of merchandise which is usually sold in sets of disassembled parts designed to be repeatedly used in the construction of various objects, structures and designs. It is particularly applicable to toy assembly sets commonly known as building blocks or construction toys.

One object of the invention is to provide assembly sets the parts of which can be easily and quickly assembled in any desired relationship and will retain their positions with out the use of fastening devices.

Another object of the invention is to pro vide assembly parts having surfaces which will adhere to each other when placed in contact but will permit of being pulled apart without great effort.

A further object is to provide assembly parts which will adhere to each other but will not adhere to a persons hands or to other ordinary surfaces such as cloth or wood.

Still further objects are to provide assembly sets inexpensive in construction and attractive in appearance which can be manufactured in a great variety of shapes and with which structures may be built of interesting and unusual design, with overhanging parts, the completed structures having such rigidity that they may be lifted and moved about without falling apart.

With the foregoing and other objects in view the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. 4

in the accompanying drawings Figures l, J and 3 are sections of individual parts each representing a different ei'nbodiment of my invention. Figure 4: shows a structure built with one of these assembly sets the parts of which are in the form of buiding blocks.

Figure 1 is a section of a piece of fibrous material such as felt, the outer fibers of which are coated with an adhesive material such as unvulcanized rubber. I prefer to apply the adhesive, not as a mass covering the fibers and closing the space between them, but as a coating for the individual fibers leaving some open spaces between them. This is accomplished by dipping the felt piece in a solution of rubber and allowing it to dry.

erial No. 3,625.

Figure 2 is a section of a part, the body 1 of which is preferably made of some rigid material such as wood and the surfaces of which are covered with a fibrous material 2 such as cloth or felt permanently glued to the surface. The outer surfaces of the cloth are coated with some adhesive 3 as described in connection with F igure l. This construc tion has the advantage. of producing a resilient surface similar to that of solid felt and also the advantage of being more rigid.

In Figure 3 is shown a section of a part. the body 1 of which is made of some rigid material such as wood and is surfaced with an unwoven fibrous material 2 known as flock which is held in place by a binder 4, preferably a hard varnish or glue. The flock fibers are coated with an adhesive 3 such as unvulcanized rubber applied as previously described.

lVhen two surfaces prepared as herein described are pressed together the projecting adhesive coated fibers which are presented to each other tend to overlap and interlock, thus the area of adhesive surface making contactis much greater than it would be with nonfibrous surfaces. The fibrous surface also furnishes increased gripping area for the adhesive so thatthe adhesive will not be pulled away when two assembly parts are separated after being pressed together. The fibrous surface also provides a certain amount of resiliency which permits each surface to adapt itself to inequalities of the other.

I prefer to use unvulcanized rubber as the adhesive because of its: cohesive quality and because it has very little afiinity for other materials, and objects coated with it do not tend to adhere to other surfaces not so coat-- ed. It also has the desirable quality of retaining its cohesiveness for a long time.

Figure 4 represents a structure built with a set of building blocks embodying my invention and illustrates the unique adaptability of this invention for making comparatively rigid structures, with overhanging portions, without the use of special fastening devices, a feature which adds greatly to the pleasure and interest of those using an assembly set of this kind.

My invention is not limited to the em bodirnent thereof hereinbefore described and illustrated in the accompanying drawings,

but may be embodied in various other forms Within the nature of the invention as it is' defined in the following claims.

I claim as my invention:

1. A changeable assembly set for amuse ment and educational purposes formed of a plurality of different elements shaped to be combined to provide a variety of structures and each having a yielding roughened surface coated With an adhesive material 'rvhich will cause the elements to adhere to each other When placed in contact and xvhi ch Will maintain its adhesive property, at the :same time permitting the ready separation of the elements for reassenibling to produce other figures.

2. A changeable assembly set for 'amu'sement and educational purposes formed of a plurality of different elements shaped "to be combined to provide a variety of structures and each having a rigid body portion, a yielding roughened s'urfaceap 'jlied.to such body portion and an adhesive coating; applied. 'to said yielding iii-oughened 'sdrface which will cause the elements to adhere to each other when placed in contactand ivhich will maintain its adhesiye property, atthe same time permitting the ready separation of the elements for reassembling to 'prdduce other "figures.

3. A changeable assembly set for amusement and educational purposes "formed of a 'p1u'ral1ty ofd ifereiitelements shaped to be combined {to provide a variety of s'tru tu'res and each a rigid body, a 'sui faceo f fibrous mater al on the body and an adhesive coating" covering the individual strand but "not entirely filling the spaces betiveen the strands, Which will cause the elements to adhere to each ether When placed in contact and which will maintain its adhesive property, at the same time permitting the ie'a d'y separation "of the elements for reasseinbling to produce ether figures.

7. A changeable assembly set for amusement and educational purposes, the parts thereof composed of a rigid material, and surfaced "with a fibrmns material, the outer fibers of the fibrous material being coated with unvulcaniz'ed rubber.

8. A changeable assembly set for amuse nient and educatienal purposes, the parts thereof composed of a rigid 'inaterial, and surfaced 'vv'ith an unwev'en fibrous material, said fibrous material bein'g'co'ated with un- "vulcan'ized rubber.
