appiication vinea Juiy 16,

This invention relates to toys and more particularly to toys adapted ,to vsimulate Such a mechanical operation as that of pumping although not in reality performing such a function. y

An object of this invention is to provide a toy of the type set forth of such .construction'and arrangement as to give the effect of a pump when operated.

A further object is to provide a device of the type described which will be simple in construction, easy and cheap to manufacture and assemble and `effective in operation.

These and other objects which-will be apparent to those skilled in rthis particular' art are accomplished by means ofthe invention illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a'n apparatus provided with one form of this invention. Fig. 2 is a plan view partly in section on the line 2M2 of Fig. 1. Fig. 3 isi a vertical sectional view showing certain of the details of theV present invention. Fig. 4 is a sectional view on the line 4-4 of Fig. 3. Fig. 5 is a horizontal section on the line 5-5 of Fig. 3 and Figs. 6 and 7 are elevational views of certain details.

The particular embodiment of this iiivention which has been chosen for the purposes of illustration includes a storage bin or hopper having an outlet orifice through which material placed therein is adapted to flow. A chute which is preferably enclosed is positioned in operative relation to the outlet orifice of the hopper so that material flowing from the hopper descends along the chute. A Suitable mechanism is employed in connection with the outlet orifice for permitting only an intermittent iiow down the chute. This mechanism is adapted to be opera-ted by any well known form of pump structure such as the walking beam illustrated and the latter is operated by any suitable mechanism. The effect of the operationof such a mechanism as the walking beam `in conjunction with the intermittent discharge of material from the end of the chute gives the beholder the impression that the material is actually being pumped.

As illustrated7 the invention includes a storage bin or hopper 10 which is placed in :in elevated position as, for example, at the top of a suitable tower 11 which may be so formed as to resemble oil or gas well derricks or the like, as illustrated. A tubeor 1926. Serial No. 122,842.

enclosed chute 12 is provided with a flaring mouth 13 which is so positioned beneath the outlet orifice 14 of the hopper that material flowing therethrough will fallin the mouth of the tube and flow downwardly there'- tlirough. The tube is secured in position by means of a curved strap 15 secured at opposite lends to the derrick or tower and secured to the mouth 13 intermediate its ends.

A suitable mechanism is employed for intermittently cutting off the flow of material through the hopper orifice.. As illustrated,

this mechanism includes a tiltable tray 16Y having vertical sides 17 formedl with'outwardly extending'ingers 18 by means of which the ytray is supported for rocking or tilting movement in diametrically opposed tray supporting brackets 19 secured to opposite sides of the hopper. The tray is adapted to be tilted by means of a connecting link 2O extending downwardly and secured to one end of a walking beam 21 pivoted to an upright 22V and adapted to be rocked by a crank 23 connected to the opposite end of the walking beam by connecting link 24 and driven by any suitable means such, for example, as the spring vmotor 25. For assembling` and packing purposes the lower end of the tray operating connecting rod is detachably secured to the associated end of the walking beam. As illustrated, this is accomplished by providing the link with a slot 26 for engaging the stem of a headed pin 27 on the walking beam. A locking lever 28 having a finger piece 29 is pivoted to the walking beam in such relation to the pin 27 that when in one position, see Fig. 7 the link' 2() is lockedagainst removal from engagement with the pin 27 while inthe other position, see Fig. 6, the link 2O is allowed sufficient movement to permit removal from the pin 27.

The hopper can be most conveniently and separately mounted upon the tower 11 by means of slots 30 formed in the walls kof the hopper for the purpose of receiving securing ears or lugs 31 formed on the tower and adapted to extend through the slots and be bent over so as to hold the hopper in place. i' f Y As will be noted from Fig. 2, one side of the base of the tower is open and the towerfis removably secured to the base member 32 by ears 33 which are struckup from the metal of the base member and bent horizontally so as to form a slot for receiving the flangesBeton Vthe base of the tower;` A similar ear 35 constitutes a stop for properly positioning `the tower on the base and-V Vertically extending lugs 36 hold the side flanges 34 in position under the securing ears 33. Any form of' receptacle 37 may be em-.

ployed for collectingr the materialdescendyingrr the tube orchute 12.

In operation, suitable material such, tor

example, as sand is placed in the `storage binV or hopperwlO. Thepmotor is startedancl the Walking beam 2l is `oscillated thereby. This causesthe cut-off tray 1G tobe tilted or rocked in its supportingbrackets in such a Way as toiintermittently cut off the flow of sand through the outlet orifice of the hopper and down the tube, as shown in Fig. 3. The

result is that the sand intermittently emerges from the lower end of the tube inV successive V separate batches which flowvthercfrom in timed relation `to the operation of the Walku ing beam. This results in the impression' that the Walking beam is. actually pumpingV material through the chute or tube 12.1 Ifdesired a toy figureSS having a movable arm 39 or the like may be positioned on the base memberwith its movable part connected vto the walking beamlby a connecting link 40's'0`as to increase the attrac-V tiveness-of the toy.
