To all whom a may concern-.-

Be it known'thatfl, Gnoncn D. PARKER,

a citizen of the United States, residing at Riverside, in the county of Riverside and State of California, have invented certain new and usefullmprovements in Conveyers, of which the following is a specification, reference being had therein to the accompanying drawing. i

My invention relates to conveyers of the class in which distinct articles are carried forward in succession by belts,gohanged in direction, transit,-and still, further advanced, all in an approximately horizontal plane.

The apparatus is especially intended for conveying a series of boxes, for example, filled fruit boxes such as are used in packi ing oranges, lemons, apples or the like, but obviously its use is not restricted to this field.

In the accompanying drawings, Figure 1 is a plan view of so much of the apparatus as is necessary to an understanding of the invention. Fig. 2 is aside elevation of th devices shown in Fig; l.

In these views, A represents an endless approximately horizontal belt driven by any suit-able means, a pulley B and belt C being shown as driving a shaft D and 'a conveyer carrying drum E thereon. The eonveyer belt runs between parallel frame bars F,

v pfeferably of angle iron, in which the shaft and the shafts of belt supporting rollers G are mounted. A second endless, approximately horizontal belt H runs at an angle with the first and with its upper fold preferably slightly below the corresponding fold of the belt A. This belt H, like the other, is supported. by rollers G mounted in frame bars F to which the ends of the bars F are secured. The second belt lies at a suitable short distancefrom the drum E, so that the articles conveyed may not fall between the two belts, the distance usually varying with the character of the articles conveyed. Above the angular space between the belts and upon that side of the first belt from which the second belt advances is arranged a fulcrum-like body lying very near the margin of each belt. Preferably this body is a drum or roller I, rotatable about a vertical axis.

Above the plane of the belt H and upon that side of the same opposite the belt A is placed a yielding bufi'er J, shown as sup- Specification of Letters Patent. Application filed February 3, i912.

ported from the corresponding frameibar F by spring members J. This buffer is curved outward beyond the margin of the adjacent belt to allow the corner of the box to swing through- :an angle-of about 90 without pressing the box backward too far, andyalso,

swung around in its own plane and its forward end portion is moved on with the second belt before the other portion has left the first belt, and the box is thus thrown against the drum I which acts as a sort of fulcrum for the article the forward end of which is urged on transversely by the second belt. Thus the rear end is swung toward the second belt and finally crowded fully thereupon, as the article finally passes the drum, in moving on toward its destination.

It is to be noted that the apparatus occupies practically no more space than the simplest conveyer, that it is inexpensive in construction and installation, and that it handles articles for which it is adapted in the most satisfactory manner and at any desirable speed. Obviously, the articles may be repeatedly changed in direction by duplicating the apparatus, and as clearly the apparatus is adapted for combination with ordinary elevating or lowering devices whenever the desired change in level is greater than that which may be readily attained by inclining the two belt conveyers above described.

Vhat I claim is:

1. The combination with an approximately horizontal conveyer for moving distinct articles, of a second conveyor moving transversely to the first and in position.to

receive articles directly therefrom, and a,

single fulcrum-like body in the angle made by the two conveyors to serve as a pivotabout which the second conveyor may swing articles passing to it from the first conveyer.

2. The combination with an endless con- Veyer belt, of a second transversely moving similar belt approximately in the plane of the first and in position to receive articles directly therefrom, and a fulcrum-like part arranged in and near the vertex of the angle made by the lateral margins of the two belts said belts forming the only support for the articles While changing direct-ion, substantially as set forth.

8. The combination with two endless belt conveyors in approximately the same plane one being arranged to deliver directly upon the side of the other,'0f a bufi'er to prevent articles from being thrown beyond the receiving belt, and a vertical roller mounted closely adjacent to both belts in the angle between them and serving as a fulcrum about which each article swings through the whole angle made by the belts.

4:. The combination with a power driven endless belt conveyer, of a second similar conveyer transverse to 'the first, closely adjacent to its end and slightly below its plane, a vertical rotary drum mounted in butter in position to the angle between the jacent to the edge of each, and a yielding articles thrown by the first conveyer to the farside of the second.

5. .The combination with two beltconveyers in approximately the same plane, form ing the only support for articles carried, one of said belts being arranged to deliver-articles transversely upon the other, of a vertical pivotal post closely adjacent to both belts and in the angle between them, and a buffer in position to prevent articles delivcred from passing transversely off the belt receiving them, said bulfer being centrally curved outward beyondthe receiving belt to permit rectangular articles to turn without belts and closely adreceive the impact ofbeing pushed too far back upon the rece1v= ing belt. a

In testimony whereof I afiix my signature in presence of: two Witnesses.
