snoasn n. wmm HISON, F JERSEY CITY, NEWJERSEY. rov.v i To all whom it may concern: Be it known that I, GEORGE H. WILLIAM- SON, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in Toys, of which the following is a specification. This invention relates to toys and has for its principal object the provision of a device of this character which will be instructive, educational and amusing; one which may be readily converted from a portable wheeled structure of one design to other portable structures: of many designs, each of a mechanical formation which will permit of its sustaining the weight of a child and capable of being propelled over the surface of the ground. With the above and other objects in view which will appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out in the claims. In the accompanying drawings, has been illustrated, a single and preferred form of the invention, it being, however, understood, that no limitations are necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired. ' In the drawings Figure 1, is a side view of the device set up in the form of a two wheeled cart. Fig. 2, is a bottom plan view of a portion thereof. Fig. 3, is a side view of the device show ing the same set up in the form of a four wheeled wagon. Fig. 4, is a bottom plan view of the forward portion thereof.

Fig. 15, is a perspective view of one of the end boar is. as used in Fig. 3. r In carrying the invention into practice, use is made of a number of stock mechanical elements all or a part of which constituting one of the many portable structures to be hereinafter specifically referred to. These elements are simple in design and are adapted to be assembled with one another for the completion of the object to be formed without requiring any extended skill of mechanics. Therefore, the device may be set up and knocked down and converted from a structure of one design to a structure of a totally different design by the inexperienced mind of a child. The device nevertheless, contains many educational features in that the various elements constituting the same may be technically catalogued and the trainin afforded a child in setting up the many di erent objects is quite material and beneficial, saying nothing-0f the enjoyment and pleasure which may be had'through the use of the different forms of structures as they are set up by the child. I have as far as is practicable, used a set of mechanical elements in which almost the same elements will be employed when changing the device from a structure of one type to a structure of a different type. In the form shown 1n Fig. 1, the same being a two wheeled cart, use is made of a platform 1, two diverging reach bars 2-2, an axle 3, having wheels 4.--4, and a pole 5. At the front end, where the reach bars come together, a small clip 6, is used which is as shown, said pole is extendedthrough the eye 8, of the clip and the rear end which is provided with spaced plates 9-9, is arranged over a removable block l0, under the reach bars and a bolt 11, is then passed through the platform 1, and through the block 10, and a small metal cross piece 12, which extends over the plates 9-9. In ad bolted at 7 beneath the said reach bars and Yo aK. - OTTO WINKLER, 0F Ci'lPE-NIGK, AND RUDGLF URTEL, OF NIEDER CI-INEVIEIBR GEE MANY, ASSIGNORS TO GENERAL ELECTRIC COMPANY, .5L CORPORATION or VALVE-GEAR FOR INTERNAL-COIJIBUSTTGN ENGINES. retail-9o. Specification of Letters Patent. Patented To all whom it may concern: Be it known that we, OTTO NINKLER, a sub ect of the King of Prussia, residing at Copenick, Germany, and RUooLr Uurnn, a, subject of the King of Prussia, residing at N ieder-Schoneweide, Germany, have invented certain new and useful Improvements in Valve-Gears. for Internal-Combustion Englnes, of which the following is a specification. This invention relates to internal combustion engines, and its object is to utilize the pressure of the expanding gases in the cylinder to assist in the movements of the valve gear. The operation of opening the outlet passage in such engines must be effected very rapidly, necessitating extreme acceleration in the movement of the valve and its gearing. By causing the pressure of the exploding charge to act upon this valve, the mechanism Which operates it is assisted and greater promptness of operation is secured. To this end we use an annular valve located inside the cylinder and actuated by a rod or stem passing out through a stuffing box in the head of the cylinder. The inlet and outlet ports or passages are both controlled by this one valve, the arrangement being such that the outlet passage is opened when the valve stem moves outwardly from the interior of the cylinder and the inlet port when the valve moves inwardly. The accompanying drawing is a diagrammatic section of a cylinder of an internal combustion engine, showing our improved construction of the valve. The cylinder 1 has an-outlet or exhaust port 2 located below the plane of the inlet or fuel admission port 3. The annular slide valve 4 controls both ports, and is actuated by the stem 5 which passes out through an opening in the head 6 of the cylinder. In practice, this opening is of course provided with a suitable stutfi'ng box or packing. When the charge has been: fired, the pressure in the combustion chamber between the head 6 and the piston 7 acts upon the cross sectional area of the stem 5 and tends to lift the valve thereby assisting the valve mechanism in effecting a quick uncovering of the outlet port 2. Moreover, when the suction stroke of the piston occurs, the atmospheric pressure on the outer end of the stem aids the valve mechanism in opening the inlet port. To state the matter in anbustion engine, of a valve locat l ins in rt 3 and later in open)- opening the fuel po ing the exhaust port With this arrangement, therefore, the movements of the valve in each direction are ed'oeted in part positively by the valve mechanism and in part automatiealtv b the unbalanced lluid. pressures on the valve and its stein. \Ve have not illustrated the means for moving the valve since able mechanism for the purpose in ployed and further because it seems unneeessary to an understanding of the invention. 'T() e able the invention be more readily understood. the moving and st. ary parts have been separated by relatively fill large clearances. In practice these make, of course, a good working in accordance with the provisions of patent statutes. we have described the principle of operation of our invention, together with the apparatus which we now consider to represent the best embodiment thereof; but we desire to have it under apparaus shown is only illustr" l the invention can lie carried means. Whatwe claim as no '7 and desire to cure by Letters Patent oi the United States, is 1. The combination with an internal core cylinder thereof and control inlet and outlet ports, and mes sting said valve both posit unbalanced fluid pressures on the viii" eluding a part eiiteiu'ling out thron end oi the c i'lindertoward which moves to open the outlet port from which end it moves to opei port.
