Patented 0a. is, 931- OTTO I. OPTERIAN, OI SEATTLE, WASHIHGTON GHILDS PQWER BHOVEL Application fled An a: 25, 1930. Serial 1a. 411,551.

This invention relates to toys, and more particularly, to apparatus of this character simulating the construction and operation of a steamshovel, the object, generally stated, being the provision of a strong, inex ensive and attractive device which will a 0rd amusement and exercise to a child.

A particular object is the provision of a device reproducing, both in appearance and activity, the characteristics inherent toa steam shovel as generally used forengineerin excavations.

he invention presents certain combinati0ns of elements adaptable for use as operating mechanisms, both in commercial and in toy sizes, and'for a wide range of tools and other working elements'which are directly applied 'to the desired dut With the above and further objects and advantages in view, such as willappear in the following detailed description and claims, the invention consists in the novel construction of parts, and in the arrange'ment and In the accompanying drawings,--

Figure 1 is a top p an view' of apparatus embodying the present invention, full and broken lines respectively indicating dispositions of associated parts responsive to swivel activity of the frame, the view particularly illustrating the invention as applied to toy excavating ap aratus. Figure 2 is a side elevation thereo the closed osition of apivoted bucket'body being ilustrated by full lines and the open position thereof by broken lines. Figure 3 is an end elevation "with parts broken away andshown in section; and

igure 4 is a longitudinal vertical section, taken substantially on line 44 of Fig. 1 with the bucket shown in its relatively extended dis osition. v

he invention simulates-the construction and operation of a powerv shovel and comprises a. .base or body portion consisting of a pair of laterally spaced skid-runners 6 a transverse bolster member 7 and a j a ck eg 8- su ported by said bolster medially of its width. r 5* A frame is designed to have swivel activity in a horizontal plane upon the aforesaid base,

verse pintle 16 is journaled and to this end a reach 9 is journalled for movement through an arc of substantially 270 about the axis of a-vertically disposed inverted king-bolt 10 which is passed through the bolster 7, jack leg 8 and reach 9, a" nut 11 engaging the king-bolt 10 at the to and securing the several arts together. The relatively movable surihces of the jack leg 8 and reach 9 are spaced by washers 12 which permit the free turning-0f the vreach 9 relative to the. base, the several arts being secured to ethei' with'a non-bin in fit.

he vertical axis aboutw ich the reach 9 swings is disposed adjacent one end of the reach and, as shown in the drawin is adjacent the rear extremity 13 of said reach, a saddle or seat 14 being secured to the latter back of the kin -bolt 10 so as tocounterbalance the weig t of the operator with respect to bucket-actuating construction hereinafter described.

The extended or forward section of said reach is suitably conformed to present a nodular projection 15throu or pivota'lly' supporting the elbow 17 of acrank-configured member 18, saidmember constituting, with lever 19, link 20, and a bucket-arm or dipperstick 21, a jointed control lever for governing the disposition of a bucket or dipper, generally represented b 22.

The crank mem er 18 constitutes a rocker arm which is provided with a rigid handle 25 for manual control at its rear end, said rocker arm being pivoted at its front end to the bucket-arm 21 a distance from but relatively near one end of the the latter, which distance is indicated by the character 21'. The link 20 is pivoted at one end to the extreme end portion of the dipper-stick 21 and at the other end to the'lever 19 intermediate theends of the latter. The lever 19 constitutes a manual control for the link 20 and the bucket-arm 21 and is pivotally connected adjacent its bottom end to the crank lever 18 and to reach 9 by means of the pintle 16. The crank lever 18 and the bucket-arm 21 are thus h which a transadapted to swing in vertical planes collec-' arm 21.

Said crank member preferably comprises two spaced-apart conjointly movable members 23, 24, arranged for straddling engagement over said integlral control lever and over thefulcrum of t e aforesaid bucket- The preferred construction of bucket 22 provides, rigid with the extreme outer end of said arm 21, a back wall 26, pins 28 .pivotally' supporting a scoop 29 by the side walls 30 thereof upon lateral flanges of the back wall. A cord '31 is secured at one end to the control lever 25 and passes through an eyebolt32 secured to the crank lever 18 andis secured' at its other end to one of the side walls 30 of the bucket 22, this cord. 31 being loose, v and thus affording a controlled discharge-of the bucket contents, as represented in dotted lines, Fi 2. v

For e ectingthe swivel activity of the reach 9 and the excavating mechanism abouta vertical axis, by the feet of the .operator.

while sitting u onthe saddle 14, I provide a cross bar 33 crumed intermediate of its ends upon a vertically-disposed bolt 35 mounted in the forward end of the reach 9, this cross bar being formed with foot-engaging recesses 34 upon both sides of its pivotal connection and being pivotally connected ad-' jacent one end to one end of a link 36 which at its other end is pivotally bolster 7. crumed to the bolster member 7 rearwardl of the vertical transverse plane of the reach axis 10 and projected therefrom, in a normal dis osition of the reach medially between the ski e-runners 6, in a manner to afiord an acute angular arrangement in its intersection with the cross-bar 33.- In this particular, attention is directed to the resultant provision for a most extensive field of operation within which the bucket or other suitable toolmay work the free swinging activity interrupted only by contact-of the ink 36 with the jackleg 8 or a swingable arrangement closely approximatin' a 270 arc. v

For facilitating the dumping operation of the bucket contents, a lock is provided for the crank lever 18, 1n various selective positions, through the medium of a lever 37 pivoted at one end in the reach 9 and having one edge formedwith a plurality of slots 39 I adapted selectively to be engaged with an extension 38 of one of the bolts which secures together at one end the two s aced members 23 and 24 forming the crank ever 18. Such engagement of the lever 37 with the crank lever 18 is shown in broken lines in Figure 2.

In operation, the action of the operators feet, 'such engaging recessions 34 of the foot bar, determines the location of the reach frame in the desired performance of a dirt or sand excavation. Pressure outwardly upon lever 19 retracts the bucket 22 into a position, cooperatively with subsequent presconnected to the Said link 36 1s preferably ful-- on the reach vertical plane,

sure outwardly uponlever 25, to disdpose the scoop member 29 adjacent the desire ground excavation. Power application upon the lever 19 effects a movement ofthe bucket about its fulcrum at the outer end of the crank lever 18 to pick up such sand or gravel as constitutes the desired excavation. Subsequent actuation of control levers 25 and .19, cooperating with the foot-actuated horizontal swinging of-the reach frame, disposes the bucket in a suitable position whereby the load, through cord 31, may be dischar ed into a miniature truck, wagon or'such ot er receptacleas may be desired.

The invention will,- it is believed, be evident from the foregoing, and. while I- have illustrated and herein described a preferred embodiment new best seen to attain the objectives contemplated, it is not my intention to particularly confine myself except by the scope of the hereto'annexed claims.
