To all whom t may concern.'

Be it known that l, FRANCIS Les STUART, a citizen of the United States, residing at New York city, county and State of ew York, have invented certain new and useful Improvements in Apparatus for Gathering and Conveying Material, of which the following is a specification.

This invention relates to apparatus for gathering material and for conveying it to the desired 'oiilt of delivery. Letters Fatent of the nited States have heretofore been granted to me for apparatus of this general kind.

My U. S. Patent No. 1,271,627 of July 9, 1918 (Case 17) shows apparatus in which the material is gathered by a.- plow and delivered t-o a conveyer belt on a boom, which is pivotally connected, to move about both vertical and horizontal axes, with a truck movable over a main conveyer belt which carries the material to its destination.

' ll/ly' present invention relates particularly to the construction of the plow used in apparatus of this kind, and also involves devices for agitating the pile of material While being gathered.

vAccording to this invention the plow is so constructed as to minimize resistance to the movement of the material onto the conveyer belt of the boom to which the plow delivers, and the boom is provided with rods or arms which serve as agitators for the pile of material in order to preserve a slope in the pile which affords the most easy gathering of material by the plow.

My improvements are illustrated in the accompanying drawings, in which Figure 1 is an elevation of the lower end of a boom conveyer equipped with my improved plow and agitating devices.

boom frame which is lettered A, and in this instance the boom is made in skeleton form, suitably braced or trussed as indicated. T he lower end of the boom conveyer belt is indicated at B, andV C indicates a frame or housing for the auxiliary conveyer belt D, similar to a belt of this kind shown in my prior patent. The skirt boards of the housing ,are indicated at c. rlhe belt D is driven by a motor E, geared as shown at e to said belt D. The housing C' is continued as shown to the outer edge of the plow F and this extension of the housing contains the rollers or sprockets f for supporting and guiding the lower or outer part of the auX- iliary beltA Vlllhe outer portion of the boom is supported by a tractor Gr and said tractor may be used for'swinging the boom conveyer and gathering devices about the pivotal connection of the boom with the truck. All of these parts are shown in my prior patent or other patents granted to me and are not herein claimed as new.

The plow F is of novel construction. The bottom plate m is preferably made straight and flat and the front and rear edge is inclined from its outer end inwardly and these. inclined edges carry teeth m, -which facilitate the entrance of the plow into the pile and the gathering of material.

The front and rear sides, as well as the inner side of the plow, are left open. lt will be observed that the plow is double acting, that is, it is adapted to gather material when swung in either direction. rllhe top plates N, lof the plow are inclined in a novel way. The plate N inclines from its inner portion downwardly toward the lteeth m and it also inclines inwardly and downwardly toward vthe boom. similarly inclined. Fach top plate N and is adapted to receive material from the teeth m and to guide it to the conveyer belt D, in the housing C. lt will be observed by` reference to Figs. 3 and a that by 'this arrangement the distance from the bottom plate m to the top plates and is much shorter at the inner part of the plow than atthe outer part thereof. rThis Vis an improvement of considerable importance, because the inner portion of the plow acts upon material atv The plate U isl conveyer belt l? quichly and with little 4 sistance. The outer portion of plow acts upon the material where the pile is thicker and, furthermore, by having the plates N and 0 at a higher elevation at the outer portion of the plow, space is provided for the roller or sprocket wheels 7.

Experience has demonstrated that a plow constructed in the manner before described operates more efficiently than those heretofore used for a similar purpose.

, lt will be observed b v reference to Fig. 2 that the skirt boards oi the casing C terminate at the inner edge of the plow and from these lower ends of the skirt lboards project plates J which serve to guide or direct the gathered material onto the conveyer belt. These plates are preferably curved in arcs having radii struck from the vertical axis about] which the boom conveyer turns.

Fhave found that material can be gathered with greater facility if the slope of the pile is maintained at a proper angle. ln Fig. 1, X indicates the natural slope of the pile on which the plow is operatingr and Y indicates the slope after the plow has operated. lt sometimes happens, however, that the pile does not maintain the slope indicated at X or Y but the material assumes the conditions shown at Z, and when in this condition the material is not so easily gathered. l have found that this diiiiculty may be overcome by providing agitators which stir or agitato the material in such manner as to cause it to assume or maintain the proper slope. For this purpose ll employ outwardly extending rods P, F', the lower rods P being shorter than the upper ones. These rods may be rigidly attached to the outer end of the boom, but preferably they are made adjustable as shown; As indicated in Fig. 2, the rods P are pivotally mounted at p and each of these rods is connected by a rod Q to adjusting devices g. It will be observed that the inner end of each rod Q, is threaded and a sleeve nut is provided at g which may be operated tol draw the rod inward or force it outward and thus adjust the agitating rod to which it is connected. Any suitable device for this purpose may be employed. Fig. 2 clearly indicates a construction which is suitable and it also indicates how the agitating rods may be adjusted in various ways. rThe lower rods P may be adjusted in a similar way.

in the operation of the plow indicated in Figs. l and 5 when the resistance of the head of the vpile is sufficient the material is pushed up the incline by the plow and falls onto the conveyer belt. it will be observed that the sliding surface N 0 in Fig. 3 is much less tha the sliding surface in Fig. Li. rihere is mulh greater depth of material over the outer portion of the plow .shown in section in Fig. A, as the material ,slides up the incline so that with less depth et ma- Lsaaeeo terial at the outer edge of the pile or the inner edge of the'plow, there is less height and distance for the material to move to reach the conveyer in the central portion of the plow. In this way there is less resistance from the material in front of the plow. lVith regard to the agitating means shown, these are believed to be of importance, but the agitating means may be varied. I have merely shown the preferred way of performing this operation.
