10 Claims.

The invention concerns a miniature form of apparatus for picking up stones, nuts, marbles or other objects to be employed as a toy for the amusement and training of children.

One object of the invention is to embody in the form of a toy some of the principles involved in full size or standard apparatus, while at the same time simplifying the construction and rendering possible its manufacture at a low cost.

The invention is illustrated in the accompanying drawings in which Figure 1 is a side elevation of the invention.

Fig. 1a is a detail view of a part of the frame and a hanger attached thereto.

Fig. 2 is a vertical sectional view on the line 2-2 of 1. r

Fig. 3 is a vertical sectional view on line 3-3 of Fig- 2.

Fig. 4 is a plan view of the machine.

Fig. 5 is a vertical sectional view through the hopper on the line 5-5 of Fig. 3.

Fig. 6 is a detail view in section on line 66 Fig. 2 of a part of the connection between the main carrying wheels or discs.

Fig. 7 is a detail view of a part of the hopper and a dumping door therefor.

Fig. 8 is a perspective view of part of the hopper, dumping door and operating connection.

In these drawings I indicates a. horizontally disposed frame member made of a strip of flat sheet metal, set up on edge, the ends of said metal strip being brought together at the rear left hand corner of the frame work and secured together by bracket 2, Fig. 4 of metal arranged on the inner side of the metal strip l and secured thereto by the nuts and bolts 3. This main frame member I is in one piece including side bars, a rear cross bar lb and a front cross bar Ic which latter is of curved formation.

The main frame member is bent into the form just mentioned.

A hanger a is secured by screws 4 to the outer sides of the side bars of the main frame and these hangers support a cross bar or shaft 5 which has a head 6 on one end. Its other end is screw threaded and receives a nut I by which the said cross bar is held in place in the hangers a. This cross rod or shaftafiords a bearing for the wheels 8 which are preferably of metal in disc form, each provided with a flange 9 forming the tread of the wheel which bears upon the ground. These discs or wheels are made of sheet metal and they may be stamped to suitable shape. These wheels are spaced from the main frame bars I by sleeves or cylindrical tubular members i0, Fig. 2 loosely threaded on the cross rod or shaft 5. Said sleeves bear on the wheels at one end and at their other ends upon the side bars of the main frame I.

The carrying wheels 8 are connected with each between these conveyor bars.

other to rotate in unison as one body by stone lifting members consisting of sheet metal pieces I3 in the form of flat bars extending from one wheel to the other. The ends 43a of these flat bars enter slots M Fig. 2 formed through the disc body portions of the carrying wheels, the fit between the bar ends I31: and the walls of the slots H or openings I 4 being such that the flat bars of sheet metal will be held against play or displacement. Augmenting the holding of these cross b'ars immovably in relation to the discs or wheels are brackets consisting of pieces of flat metal bent substantially at right angles so that onepart l5 of the brackets can be attached by screws or bolts Hi to the face of the crossplates I3, Fig. 6 and the other part 15a of the bracket can be attached to the web or disc of the carrying wheel by the screws or bolts ll.

These cross plates or bars attached to the carrying wheels or discs make them move in unison. The plates or bars have each a series of stone lifting arms l8 which are spaced apart from each other so as to pass between track or stone conveyor or directing bars l9. These conveyor bars is are each in the form of a loop encircling the cross shaft or bolt '5 and having its forward ends secured to-a cross bar 20 of strap metal which extends between the'side bars Ia of the frame. The connection between these side bars and the cross bar 20 consists of the foot portions 20a of the cross bar bolted or screwed to the side bars on the inner side thereof.

These spaced apart conveyor bars form a grid. The stone lifting arms have travelling movement The stone lifting arms describe a circular path which carries the ends of the stone lifting arms close to the ground so that any stone or similar object which lies in the path of these arms will be picked up and moved along the conveyor bars towards the front of the machine where they are discharged in a forward direction into a suitable hopper. The

stone lifting arms register with and travel along 1 the spaces between the conveyor bars.

These conveyor bars are supported by the means above described substantially fixedly to.

the cross bar of the frame. The stone lifting arms are fiat and may be stamped or cut out of the sheet metal piece which furnishes the sheet metal connecting plates between the discs of the carrying wheels.

The stone lifting arms participate in the revolution of the carrying discs or wheels but have no independent movement relative to the carrying wheels. They have no individual pivotal or other movement, but revolve as integral parts of the carrying wheel organization. The stone lifting arms are long enough to describe paths that reach near to the ground so as to contact any stones or like objects that'lay in their paths.

These stone lifting arms cooperate with a plate lifting arms.

The stone lifting arms push the stones upwardly along this guide plate which acts to direct the stones and prevents them from flying 03 at a tangent. This guide plate is long enough to insure the lodgment of the stones onto the conveyor or director bars l9 and their movement forwardly and downwardly along said conveyor bars to be deposited in the hopper designated generally by the reference character A. In other words, the guard plate 2i reaches over the grid made up of the spaced apart conveyor bars it far enough (see Fig. 3) vthat there will be no danger of the stones flying off at a tangent. This guard plate is imperforate. It is of sheet metal and its curvature corresponds closely to the curved paths described by the stone lifting arms.

The conveyor bars are supported only at their front ends for which purpose one end No of each bar bears against the rear face of the cross bar 20 and the other end of the conveyor bars contact the front face of the cross bar 20 and a bolt or screw 22 passes through the ends of the conveyor bars and through the cross bar 25. The curved guard plate 2| is held in fixedrelation to the organization by bolts or screws 23 connecting said plate to a metal member or strap 26, which is hung from the main cross bolt or shaft 5.

The apparatus being in miniature or in toy form is not intended to be operated under adverse conditions and therefore there will be little or no need for self adjustment or a yieldable quality in certain of theparts. Thus the con-- veyor bars i9 need not have yielding capacity but may be substantially rigidly mounted instead of being constructed and arranged to yield to prevent clogging of the material passingthrough the stone picking and conveyor means.

The hopper A is mounted within the forward part of the main frame. This hopper is mounted within the strap of metal comprising the main frame by bolts or screws 25. The wall of the hopper increases in height towards the front of the apparatus, the cross wall 26 being the highest so that it will prevent any stone or other object escaping over it to the front of the machine.

The hopper has a bottom wall 21, Fig. 5, which inclines from the central portion to each side so that when the side doors 28 are opened, the contents of the hopper will be discharged by gravity off to one side of the path of travel of the machine. Each of the side walls is pivotally mounted at its lower portion by fixing it to a rock shaft 29 suitably mounted in the hopper structure, said rock shaft having an arm 30 from which a flexible connection 3i extends through a guide to a point where the user may operate it for dumping the hopper by opening the door or doors.

The side doors are under pressure of spring means 35 by which said doors are closed automatically.

The forward end of the main frame is mounted on caster wheel 32. For mounting these casters they each have a stem or shaft 33 mounted to turn in an elongated bearing 34 secured to the main frame bar on the inner side of the same. The shaft is held in the bearing by any suitable split pin or other fastening.

The toy is adapted to be propelled by means of a handle. This consists of the handle 36 proper and a piece of strap metal 31 secured to each side of the handle 38 and extending respectively to the opposite ends of the main cross rod or shaft on which the strap metal member '31 is mountedso as to turn thereon. The parts mounted on the shaft or bolt 5 will retain their positions so long as the bolt 5 remains in the position it is intended to occupy, and for maintaining it in said position a nut I is employed.

The flexible connection or cord 3i used for operating the dumping doors of the hopper extends through the guide eyes 39 to a point within easy reach of the user for manipulation of the hopper doors. a

It will be noticed that the construction is simple. The main frame is composed of a single piece of strap metal bent into the desired shape, and having its ends brought together and fastened by a suitable coupling piece or bracket 2. This single strap of metal is set up on edge and affords bearings for the main carrying wheel organization, for forward caster wheels or other guiding means at the front of the toy. It also furnishes support for hopper means as well. as for a handle for propelling the appliance and for a support for a guard or shield which cooperates with the stone lifting arms in directing the stones upwardly and forwardly onto the conveyor bars it.

The carrying wheel structure and the stone lifting arms and the carrying bar or plate therefore are built into an organization whereby economy of manufacture is enhanced.

The main frame member of strap metal provides the spaced apart side bars which are arranged parallel with each other and this single strip of comparatively thin and light sheet metal also provides the cross bar at the rear and the cross bar at the front. Being set up on edge this frame bar though thin is strong and durable and affords ample support for the hopper at the front of the appliance.

- The main carrying wheels instead of being stamped out can be formed by forming the flange 9 separately from the discs 8 and then uniting these parts in any suitable manner including a driving fit.

The cross bar 20 to which the forward ends of the conveyor bars is are attached is provided with forwardly bent end portions fitting against the inner sides of the side bars of the main frame and bolted as at 20a to said side bars.

By fitting portions of the plates which carry the stone lifting arms in slots of the carrying wheels the driving of the stone lifting arms can be accomplished without straining the connections between the plates i3 and the carrying wheels.

The guide plate H is made of one piece of sheet metal which is imperforate and presents a smooth unbroken surface upon which the stones will pass as they are lifted by the lifting arms. This form of plate will guide the stones, and being imperforate there willbe no openings in which a stone may lodge and cause a jam and damage..

This guide plate besides being supported at its lower front end by the sheet metal strap 2 is also supported from the rear cross bar of the frame I as shown in Figs. 3 and 4 by the bolts Ila.

The carrying wheels 8 are provided with hubs 8a preferably made hollow and of sheet metal pressed into the shape shown and fastened to the sheet metal discs 8 by projections 8b.
