To all whom it may concern: 7

Be it known that I, BENJAMIN F. BAIN, a resident of Pittsburgh, in the county of 1 11- legheny and State of Pennsylvania, have 1nvented a new and useful Improvement 1n Mechanical Toys, of which the following is a specification. v

This invention relates to mechanical toys, and particularly gravity operated toys.

The object of the invention is, to provide a new and. improved toy which simulates the action of a crane or derrick such as is used for transporting buckets of dirt or rock in excavating for buildings, and which requires some attention on the part of the operator so that it stimulates and holds the interest of theaverage child.

A further object of the invention is to provide a new and improved toy of this class embodying a car or bucket which is filled at one point with sand or other operatlng medium and is thereby moved by gravity in a plurality of planes and discharges its load at a distance from the place where it is filled.

A funther object of theinvention is to provide a new and improved toy of this class in which the bucket carrying member is moved in one direction by-the weight of the load placed in the bucket and is returned to initial position after the bucket is discharged, by gravity.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

In the drawings, which represent one {embodiment of the invention, Figure l is a front elevation, showing the bucket being loaded; Fig. 2 is a similar view, parts being omitted, and showing the bucket being dumped; Fig. 3 is a plan view-corresponding to Fig. 1, the hopper being omitted; Fig. 4 is a perspective view of the lower portion of the hopper and a part of the support therefor; Fig. 5 is a similar view of the lower portion of the bucket carrying frame; and Figs, 6, 7, 8 and 9 are detail views of various parts of the mechanism, Fig. 9 being a view of a bracket as seen from the' right in Fig. 1.

The toy shown in the drawings comprises a suitable base, shown as a sheet metal tray 1, having, its edges turned up to form shallow side Walls therefor. At one end of said tray is an upright frame for supporting the sand hopper and at the other a similar frame for supporting the movable bucket carrying member. The hopper supporting frame is shown asv formed of two strong bent wire members 2 attached at their upper ends to the hopper or bin 3 and connected intermediate their ends by a rigid crossarm 4. The

lower ends of said members are bent laterally to form feet 5. The. cross arm 4 is its opposite end is then connected in a similar manner with an apertured portion of the front wall of the tray 1. The lower ends of the two wires 2 of the frame are then pressed together and their feet 5 allowed to spring into openings, one in an end wall of the tray 1 and the other in an opening in an ear 8 cut out of the bottom of the tray and bent into vertical position.

The hopper 3 is funnel-shaped with its lower end open and arranged to discharge into a scoop-shaped delivery member 9, which is pivotally connected at 10 to the lower end of the hopper. Said delivery member hangs just below the opening in the hopper in a position to receive the operating medium contained therein, which may be sand, marbles, fine shot or any other suitable substance. The delivering scoop 9 is provided with a depending bent arm 11, so

located as to be engaged by the movable bucket or the support therefor as it approaches the hopper to turn the delivery member to discharge positiomas shown in Fig. 1, in which position the operating me: dium passes out of the hopper andmember 9 into the car. When the car leaves the filling position shown in Fig. 1 the scoop 9 swings to the position shown in F' 4, in which position the operating medium, if

sand, piles up in said scoop under-the opening in the hopper until the natural angle of the material cuts ofi' further flow of the sand, and the position ofsaid scoop prevents the sand from escaping therefrom. The

cross arm 4 also has rigidly attached thereto a bent metal stop 12 on the side of the standard occupied by the bucket when being filled, and which is arranged to holdthe bucket 36 until it receives a full or operating load and then release the same, as more fully hereinafter described.

The movable bucket 36 is supported by a suitable frame shown as formed of thin strips or bars 13 riveted or otherwise rigidly secured together, one of said bars having a hinged brace 11 secured thereto. This frame is attached to the base 1 in" the same manner as the hopper supporting frame, by

first engaging a laterally extending foot 15 on the lower end of the brace 14 with an aperture in the back wall of the tray 1 and then pressing together the lower ends of the frame members and allowing the laterally projecting feet 15 on the lower ends thereof to enter apertures, one in the back wall of the tray and the other in an ear 16 bent up from the bottom surface thereof. At its upper end this frame is provided with one or more stationary sheaves or drums 17 (one being shown) formed of two sheet metal disks riveted together and having their peripheral portions bent to form an annular groove or channel 18 therebetween. A part of the periphery of the disks is cutaway on one side, as at 19, and one end edge of the bent peripheral portion of each disk is provided with a notch, marked 20 and 21 respectively, for a purpose which will hereinafter appear. A cross member at the bottom of the frame is provided with an outwardly extending arm 22 whose extreme end is bent back upon itself to form a horizontal ear 23 having a small aperture therein and lying directly below an aperture at the cen-- ter of the drum 17. These two apertures form bearings for the swinging bucket carrying frame 24, which consists of a bent strip or bar having parallel arms 26 attached toits top and bottom, said arms being provided with pins or trunnions 27 entering said bearings. The swinging frame is assembled in the stationary ilpright frame by first inserting the upper pin in the hole in the drum 17 and then inserting the lower pin in the opening in the car 23. The frame drops to a position in which the pin con-- tacts with the body of the arm 22, as shown in Fig. 1, which prevents it from dropping farther, and in which position the upper pin is still fully engaged with the opening in the drum 17.

The swinging frame turns about a vertical axis and carries two pivoted members, both of which turn about horizontal axes thereon. One of said members is an arm 28, shown as formed of two narrow metal strips riveted together andhaving their lower ends spread apart to form a yoke embracing and pivotally connected at 30 to a similar sheet" metal yoke 29 rigidly secured to the lower end of the frame 24. The arms of the yoke on the pivoted arm 28 are provided with a plurality of oppositely disposed openings 31, any pair of which may be used for the pivot pin, in order to adjust the length of the arm 28, when desired. The upper ends of the bars forming'the swinging arm 28 are alsospread apart to form a yoke 32, whose arms are-provided with inwardly extending projections 33 which enter openings in the side walls 34 of a car or bucket 35, so that said bucket or car is pivotally mounted on the end of the arm'28. This bucket is formed of sheet metalwith side walls 34, an end wall 36 and a bottom 37, and the openings in the side walls are so located that said bucket normally hangs in aposition with its bottom inclined downwardly away from the discharging end, as shown in Fig. 1, so that a load deposited in said car beneath or behind said pivots will be held therein by gravity. Said bucket is provided with a depending arm 38 located in a position to strike the-front inclined portion 39 of the stop 12 as the bucket approaches the hopper 3 and cause the bucket to tilt until it reaches its final filling position when said arm drops in behind a more abrupt portion 10 of the stop 12, with the car in its normal position.

Preferably, the weight of the empty car and its supporting arm, balance the counterweight when the car is in a position intermediate its limits of travel in both directions, so that the last portion of its movement in each direction is due to momentum. When the car moves to filling position the momentum is sufiicient to oscillate it on its carrying arm and move the arm 38 in behind the stop 12, in which position the car is temporarily held or retained by said stop until it receives a full operating load, both by reason of the friction between arm 38 and stop 12 and also because the car must be tilted on its pivots 33 to disengage the arm .38 from behind the stop. The load is deposited in the car. behind its pivots 33, or the car-bottom is inclined, as in Fig. 1, so that the load collects at the back of the car. A full operating load is the quantity of the operating medium required to overcome any friction between the arm 38 and stop 12, tilt the car about its pivots 33 until the arm 38 is released or disengaged from behind the stop 12, and also produce sufficient momentum to carry the car to discharging osition. The abrupt portion 40 of the sto 12 is preferably slightly inclined, as shown, to increase the width of the opening toreceive the arm 38 and also to decrease the friction and enable the car to leave the stop with a minimum operating load.

The arm 28 and the bucket carried there.-. by are supported by a suitable flexible mmber, shown as a cord 41, having one end attached to the arm 28 intermediate its ends, and which cord passes over an idle pulley or sheave 42 carried by the frame 24 and then around the groove or channel 18 in the drum 17. The opposite end of the cord is knotted and is passed through the notch 20 in the lower disk of the drum 17 -so that it is fixedly and removably attached thereto.

Intermediate its upper and lower ends the frame 24 is provided with a yoke 43 to which is pivotally connected an arm 44 having a suitable counterweight 45 secured to its opposite end. Said arm and the counterv'eiglit are supported by a flexible member,

shown as a cord 46, one end of which is attached to the arm 44, and which cord passes over an idle sheave or pulley 47 car- I ried by brackets on the frame 24 and-thence around the groove or channel 18 in the drum 17. The opposite end of the cord is knotted and is passed through the notch 21 in the upper disk of the drum, so that it is fixedly connected to said drum, but is removable therefrom.

Suitable means is also provided for tilting the bucket. when it reaches discharging position for dumping the load therein. In the form shown this comprises a flexible operating member, shown as a cord or cable- 48, one end of which is attached to a fixed portion, shown as a depending arm 49, on the car, and the opposite end of which may be attached to a suitable part of either of the

frames

13 or 24, but is shown as at-- tached to the hands 50 of a manikin or figure 51. Said manikin is fastened to a sheet metal frame 52 having upper and lower pins or trunnions 53 which turn in apertures in the arms 54 of a bracket attached to the stationary frame 13. The upper of said apertures is to one side and in front of the lower aperture, so that the axis about which they manikin swings is inclined toward the front of the machine and also toward the hopper. This causes the manikin to always tend to swing by gravity to a position facing the hopper, as shown in Fig. 1. With the manikin in this position. and the bucket under the hopper, the cord 48 is slack, but as the bucket leaves the hopper the cord becomes taut and after turning the manikin away from the hopper actuates the bucket to dump its contents.

The toy operates partly by gravity and partly by momentum. When the bucket is in filling position,'as shown in Fig. 1, the arm 28 is in its highest position, due to the fact that a greater length of the cord 41 is in contact with the drum 17, so that the effective portion of said cable extending from the drum to the arm is shorter.. The

from its pivots, due to the fact that only a small portlon of the cord 46 is in contact In filling position, one of the yoke arms 32 contacts with the arm 11 and holds the delivery memberin discharging position, so that the sand flows into the bucket. The bucket is retained in filling position by the stop 12 and when it has received a full operating load the arm 38 on the car moves out from behind the stop 12 and releases the car. Said bucket is released suddenly and the frame 24 begins to swing around its vertical axis. The bucket gathers momentum and its speed increases as the frame swings. During the swinging movement of the frame the arm 28 carrying the car swings downwardly about its pivotal connection with the frame 24, while the counterweight-carrying arm 44 swings upwardly, due to the fact that the cord 41 supporting the one arm is unwinding from and the cord 46 supporting the other arm is winding up upon the drum 17. As the latter arm 44 rises the effect of the counterweight increases, due to the fact that it swings outwardly and upwardly and its effective lever arm increases in length. The momentum of the bucket carries it somewhat beyond a position in which the gravity effects of the loaded bucket and counterweight are equal and to a point where the cord 48 becomes taut. When the manikin 51 is used it has been swung to a position facing the bucket. Slight further movement of-the bucket, due to its momentum, produces a pull on the cord 48, which tilts the bucket and discharges the load. The load may be deposited upon a pile 0211 the floor, or if desired, in a suitable'receptacle 55 placed in the proper position to receive it.

When the bucket is emptied the gravity effect of the counterweight 45 is much. greater than that of the'empty car, so that said counterweight swings the frame 24 in the opposite or return direction about its vertical axis, thereby returning the car to loading position. As the bucket moves' back the arm supporting the same rises and the arm carrying the counterweight drops,

due to the winding'up of the cord 41 upon and the unwinding of the cord 46 from the drum 17. The car finally reaches its initial position with its arm 38 behind the stop 12, whereupon another load of sand is deposited therein and the operations are repeated.

In order to adjust the several parts of the mechanism to operate most efi'ectively it is sometimes desirable to adjust the lengths of the several supporting or operatin cords or cables. This may be done by tying aknot therein or attaching a new cord of the proper length. Preferably, however, each of the cords is provided with an adjusting member, shown as a turn buckle consisting of a bent thin sheet metal member 56 'which are bent into spiral form'to form a thread for receiving a common screw eye 57,

which is'attached to the member to-be supported or the support therefor. This is a simple construction which permits of ready adjustment of the length of the cord to either increase or diminish the same, but it is not essential and anyother suitable adjusting means may be employed.

The partsshould be so adjusted in assembling that the load is deposited in the car from the hopper just under or slightly back of the pivotal connection between the bucket and the arm carrying the same so that the bucket will not be tilted by the load and deliver the same before it reaches final delivery position. One way of doing this is by shifting the pivot 30 between the lower end of the arm 28 and the frame 24 to a new set of'holes 31 in said arm. This changes the length of the arm 28 and adjusts the location of the bucket 35 beneath the hopper.

A more convenient adjustment, however, is

afforded by the turn buckle in the cord 41,

whose members can be relatively rotated toincrease or diminish-the length of said cord -to thereby adjust the arm 28 about its pivotal connections with the frame24. This adjustment may also be resorted to for correcting the operation of the toy in case the surface of the abrupt portion 40 of the stop 12 becomes corroded, so that friction between said stop and the depending arm 38 on the bucket is increased. If this happens the car will take a heavier load before it is released from the stop 12, and if the load is too heavy the increased momentum of the bucket moves it too rapidly and with too much force toward discharging position. By slightly increasing the length of the cord 41 the arm 28 is lowered and the pivotal connection between the arm 28 and bucket 35 is moved to one side of the delivery member 9 beneath the hopper, that is, to the left in Fig. 1. The load is consequently delivered to said bucket behind the pivotal support therefor, so that theweight of the load is exerted,through a longer lever arm and has a greater tendency to tilt the bucket about its pivots and swing the arm 38 from behind the stop 12. Consequently, although the friction between the arm 38 and stop 12 may be greater, the normal operating load will release the bucket from the stop. On the other hand, adjustment of the turn buckle to shorten the cord 41 will increase 1 48 is attached, should preferably be located between the pivots on the bucket and the dumping end of the car, and also beneath said pivots. As'shown, said arm and the arm 38 are integral portions of a bent metal member riveted to the bottom of the bucket.

While the toy shown is arranged to be operated by sand, fine shot or other similar substance, it will of course be understood that it may also be operated by ponderous bodies of definite weight, such as marbles or the like. In this case the hopper or bin carrying the supply of marbles will be arranged to deliver a single marble or load to the bucket each time it reaches the hopper, and which will be sufficient to swing it to discharging position in' the manner-before described. Any suitable arrangement can be utilized for controlling the delivery of the loads from the bin to the bucket and for discharging them from the bucket, such, for

example, as that shown and described in my prior Patent No. 1,113,945., dated October 20, 1914.

The toy described simulates the action of a crane or derrick such as is used in excavating for buildings. It operates continuously and is automatic as long as a sufiicient supply of the operating medium is in the hopper. The necessity of returning the sand from the delivery point to the hopper requires the atten tion of the operator, so that the toy interests him for this reason as Well as by its own movements. It isso constructed that it can be readily taken apart or assembled by any one without the use of any special tools or appliances. It can be shipped in knock down condition and requires only a small amountof space so that it can be packed in a small package.
