\ 3 Claims. 1

The invention aims to provide a simple, yet entertaining toy with which a child may pretend to be threshing grain,filling a silo, etc.

In carrying out the above end, a blower casing is provided containing a motor-driven fan, said casing having an inlet for chaff, dry bits of grass or paper, bran, or other loose material, and being provided with a discharge pipe through which the material will be blown to simulate the discharge from a threshing machine or that from a silo filling machine. As the chances are great that the child will endeavor to insert sticks and the like into the blower casing, afurther object of the invention is to make novel provision whereby danger of injury to the toy will be minimized.

Another object is to provide anovel feed means including a horizontal plate or table from which the child feeds the loosematerial into the blower casing, with his fingers. I

Figure 1 of the accompanying drawing isa top plan view partly broken away and in horizontal section. v

Fig. 2 isa side elevation partly broken away and in section.

Fig. 3 is an enlarged detail vertical sectional view on line 33 of Fig. 2.

Fig. 4 is a side elevation of a different discharge pipe section which may be substituted for that shown in Fig. 2.

The general construction shown and described, may be considered as preferred, with the understanding, however, that variations may be made within the scope of the invention as claimed.

Upon a suitable horizontal base 5, a blower casing 6 and an electric motor I are fixedly mounted in axial alinement, the motor shaft 8 being provided with a fan 9 in said casing. One side wall In of the casing 6 is fixedly and permanently mounted while the other side wall I I is readily removable. This side wall II fits within the peripheral wall I2 of the casing 6, as shown at I3 in Fig. 1, and is provided with a circumferential rib I4 which abuts the adjacent edge of said wall I2. It will be noted that the casing of the blower is of cylindrical shape, the peripheral wall I2 being a cylinder, the rear of which is closed by the circular wall I9 integrally secured to the wall I2. The front end of the peripheral wall I2 is closed by the front wall I I. Two spring arms I are secured to the outer side of the wall I2 and are provided at their free ends with substantially V-shaped detents I6 which yieldably engage the rib l4 so as to normally hold the casing wall I I in place, yet to permit removal of this wall II by means of outward pressure exerted thereon. Thus, if the fan 9 crowds a stick or the like against the side wall II, this wall will" simply be forced off, minimizing danger ofinjury to the toy.

The casing wall I I is formed with. an inlet opening I! having a straight lower edge I81 and straight vertical edges I9, and preferably a straight upper edge 20. Opposite theopening I1; at the outer side of the wall II, is asteeply1inclined plate 2|, the lower end of whichis suitably secured at 22. tosaidwall H, at the edge I3 of said opening H. The plate 21 diverges upwardly from the wall II andv is provided with triangular side flanges 231 which are secured to the wall II along the vertical edges I 9v ofthe opening H. The inner edges of these flanges. 23 may well be flanged at 24' to. be fastened at 25' to the wall I I, to secure said flanges 23 to said wall. A horizontal plate or table 26 is secured tothe upper end of the inclined plate 21 and projects outwardly therefrom, said, plate or table 26 having upwardly diverging side flanges" 21 which extend from its outer end' to the wall I I', the inner portions of said flanges 2 1 being disposed at the upper ends of the aforesaid flanges 23. This structure provides for the support ofloose material to be fed into the casing by the child, and he may readily push such material from the plate or table 26 into the chute formed by the plate 2I and its flanges 23, so that the material will be readily guided into the casing. The lower edge I8 of the opening H, in this regard, is preferably transversely inclined as shown in Fig. 3. Also to prohibit the child from inserting his fingers through the upper portion of the opening H, a barrier 28 may well project downwardly from the upper edge wall 20 of said opening.

The peripheral casing wall I2 is preferably provided with a laterally projecting stud 29 receivable in an opening 3!] in the rib I4 of the wall I I, to properly position this wall and hold it against rotation.

An outlet opening 3| is formed in the casing Wall I2 and communicates with a lower fixed pipe section 32 which is secured to said wall. An in- .clined pipe section 33 (Fig. 2), or a vertical pipe section 34 (Fig. 4), may be engaged with the section 32. Pipe section 33 is formed with a cowl 35 for so directing the material discharged through the pipe as to simulate the straw discharge from a threshing machine. Pipe section 34 has a cowl 3B which will downwardly direct the discharged material to simulate a silo filling operation.

From the foregoing taken in connection with the accompanying drawing, it will be seen that novel and desirable provision has been made for carrying out the objects of the invention. Chaff or any other loose material fed into the casing will be discharged through the delivery pipe in a manner to simulate the discharge from a large machine and will be very pleasing to children. If the child endeavors to insert a stick or the like, it may be struck by the fan and immediately ejected, but if it should be crowded forcibly against the wall II by said fan, this wall will simply be forced off and no injury to the toy will be caused. This wall is also readily removable to permit cleaning of any accumulated matter from the interior of the casing 6.

It is preferable to provide the wall I! with air inlet openings 31 for admitting more air to the casing than that which can enter through the opening [1 which may be more or less filled at times with the material being fed into the toy.

Attention is again invited tothe possibility of making variations within the scope of the invention as claimed.

I claim:

1. A toy. comprising a base, a substantially cylindrical blower casing mounted on said base and comprisingan upright back wall and a peripheral wall projecting therefrom and formed with an outlet, a discharge pipe extending from said outlet, a bladed centrifugal fan in said casing having its axis concentric with an opening in said back wall, means for supporting and rotating said fan, areadily removable front wall for said casing having a peripheral portion to engage and seat on the entire front edge of said peripheral wall of the casing, said front wall having an inlet positioned to one side of the axis of rotation of said fan, a feed chute secured to said front wall and communicating with said inlet, and yieldable spring catches normally holding said front wall on said peripheral Wall, said catches being yieldable to release said front wall by excessive outward pressure upon it, whereby a stick or the like inserted through said inlet and crowded by said fan against said removable front wall, may

4 force it off of said peripheral wall instead of causing damage.

2. A toy comprising a substantially cylindrical blower casing having a peripheral wall formed with an outlet, said casing including a fixed side wall rigidly secured to said peripheral wall and a readily removable side wall provided with an inlet to one side of its center and having its peripheral portion seated on one edge of said peripheral wall, a rotary fan in said casing having blades to move past and close to said inlet, and yieldable means normally securing said removable side wall in place, said yieldable means being releasable by outward pressure on said removable side wall, whereby a stick or the like inserted through said inletand crowed by said fan against said removable side wall, may force this wall ofi instead of causing damage.

3. A toy comprising a base, a blower casing mounted thereon and comprising a cylindrical wall forming the periphery of the casing and provided with an outlet, an apertured rear wall secured to one edge of said peripheral wall and a readily removable front Wall to telescope within the other edge of said peripheral wall and formed with a circumferential rib abutting said other edge, said rib having an opening. a positioning stud on said peripheral wall to enter said opening, said front wall having an inlet to one side of its center, an inclined feeding chute secured to said front Wall at its inlet and formed withxa horizontal feeding table at its upperfront edge, the top of said table being positioned in a plane below the top of said'inlet, a downwardly projecting barrier in the top of said inlet terminating adjacent to the plane of said table, a centrifugal fan in said casing having its axis concentric with the aperture in said rear wall and provided with blades to rotate past and close to said inlet, means for supporting and rotating said fan, and yieldable catch springs secured at one end to said peripheral wall and having their other ends formed with V-shaped detents to yieldablyengage said rib to releasably hold said front wall of the casing.
