Application filed June 25, 1925. Serial No. 39,469.

The present invention relates to toys of various types such as trucks, excavators and extension ladders wherein two parts are arranged to have relative movement more or less in imitation of mechanical devices in common use, its object being to provide in such devices apparatus which may quickly and at a single operation be set in initial position by the relative movement of said parts in one direction, and thereafter so operate, when released, as to cause the toy to perform its other or reverse phase of movement in slow-motion fashion. More especially it is a purpose of the invention to provide actuating mechanism of the class stated above which shall be inexpensive and not liable to get out of order, and which in its operation shall appeal to the natural curiosity of the child.

In the drawings, which show the invention applied to a toy truck,-

Fig. 1 is a side view, parts being broken away, showing the parts in normal or loaded position; Fig. 2 is a side view, the body being elevated;

Fig. 3 is a plan view, parts being broken away; Fig. 4 is a longitudinal vertical section through the actuating or body-dumping motor I Fig. 5 is a front elevation of the follower for the sealing means of the piston;

Fig. 6 is a part section corresponding to Fig. 4: but showing a modification.

In the particular embodiment of the invention shown, one of the relatively movable parts is the truck chassis which may be of conventional construction such as is ordinarily found in toys, including the side bars 1, rear crossbar 2, intermediate crossbar 3, wheels 4 and 5, and cab 6.

At their rear ends the side bars carry depending brackets 7 on which the body, the other relatively movable member,-is mounted to tilt by means of the deep bracketsS, which extend downwardly from the body structure, and pivots 9. The

' frontend of the body, when in lowered position, rests on a chair or chairs which may be formed from a sheet metal Z-bar arranged to rest on and extend across from side bar to side bar to thus brace the chassis. When the body is in loweredposition it is retained and held from tilting by a latch 10 which is mounted on a pin 11 the axis of which extends longitudinally. of the vehicle, said latch being preferably of spring metal and having its upper end bent considerably therefrom and which may be bent from a strip of metal as shown soldered or otherwise secured in position. These brackets receive and form bearingsfor the corresponding ends of a cross-bar 20 upon which is mounted, midway of the side bars, mot'or} mechanism comprising a cylinder and piston, the latter being pi'votally connected I at 21 to abracket 22 fixed to the lower side of the body. It will be apparent that the parts might be reversed so that the cylinder would be connected to the bracket 22 and the piston to the cross-bar 20, but the arrangement shown is preferable. S5

The barrel of the cylinder is preferably from a piece of tubing 23 having its lower end closed by ahead 24 soldered or otherwise secured. thereto and apertured to receive the cross-bar 20, although other constructions such as the sheet metal head 24- and clip 24" (Fig. 6) maybe used. The upper end of the barrel is provided with the head 26 preferably soldered thereto and perforated for the passage of the piston rod 27 to the inner end of which is attached by means of the screw 28 a piston consisting of the metal plates 29 and 30 between which arearranged a cup-shaped leather or other sealing element 31 and a metal pressure plate 32 whoseouter edge is notched as indicated at 33 to form a resilient follower. for the flange" portion of the leather whereby the latter is held closely to the cylinder wall in the outward movement. and permitted to collapse inwardly during the reverse stroke. The piston is provided with a small perforation or passage 34, and between the plate 29 and the head 24 is in serted a helical spring 35 of considerable tension and of such length as to tend to push the piston to the limit of its outward stroke. Preterably both the head 24- and the plate 29 are flanged to receive the ends of the spring to prevent the latter from contacting" directly with the cylinder wall. The

head 26 has an inward extension 36 thelength of which is greater than the depth of the piston cup so that the leather is precluded from coming in contact with the head when the piston reaches its outermost posi tion,

The space ctwoen the head 24: and when in the position shown, is e or other suitable d necess ily comes i,- -iston rod l have provided a wiper the torin of fiber or leather washer 4-0 which is inserted between an outwardly fins; seat in the head 26 and a cap *ufllCll is scr w threaded thereon. Preferably the was is formed initially with a cross section of the same shape as the space between the cap and 1 seat so that there is substantially no l tortion of the washer as the cap is adjusted thereaginst, which allows an e ctive wiper act'on without ca a friction sutl' 'ent to interfere meter 1 with the movement of the piston For nailing purposes either the head 24 or the head 26 or both is perforated and provided with a threaded removable plug i3d l.

found that there was a ten 1e truck body was in its A and left idle for a consider a ole time, i0: o'l to escape through the piston d gland, this being caused apparently by compression, of air in the upper part of the cylinder when the piston rod was fully received therein. This ditliculty I have overcome preferably by making the piston rod hollow and by perforating it at the point 41-5 (Fig. l), which is so positioned as to be just at the left or inside of the extension 86 and at the upper side of the piston rod when the latter is at the innermost limit of its movement. Pressure within the cylinder thus freely relieved without causing loss of liquid inasmuch as the inclined cylinder is preferably tilled so that the level of the liquid is then below the point 4-5, and the outside air is i mwhen follower then holding the leather closely against the cylinder.

it is desirable, as heretofore pointed out, that the axis about which the cylinder swings, well as that about which the body tilts, be arranged appreciably below the side bars in that there is thus permitted the use of a cylinder of length suiilicient to insure a long stroke t-c ether with an effective levere of the power arm or motor about the ivots 9,. The connections nay be arranged ortl'ierwise,
