I tion' is the provision of feeding means for use with a feeding conveyer, whereby a conveyer may automatically feed itself or pick up the material to be conveyed. Another object is the provision of a combined excavating and conveying member whereby material may be fed to a reciprocating conveyer in response to the reciprocation of the convey'er. Another object is the provision of means for extending such a conveyor and feed member, in order to permit prolonged feeding without frequent adjustment. Another object is the provision of articulating means for permitting lateral movement of the feeder and conveyer and of relative movement, lateral and otherwise, of the feeder and the various sections of the conveyer. I

Other objects will appear from timeto time in the course of the specification and claims We illustrate our invention more or' less diagrammatically in the accompanying drawings, wherein- Figure 1 is a vertical longitudinal section of a typical conveyor;

Figure 2 is a similar section, in cont-1nua-. ac tion of. Figure 1, illustrating the feeding member as applied to the conveying member;

Figure 3 is a plan view, Figure 4 is a bottom plan view, with'parts' cut away, showing the intersection between the conveyer section and thefeeding member; Figure 5 is a section on the line 5-5 of Figure 4;

Figure 6 is a Figure-5; v 40 Figure 7 is an enlarged detail view of the feeding mechanism; and

Figure 8 is section taken on the line 8-8 of Figure 2.

Like parts are indicated by like characters throughout the specification and drawings.-

Whereas we do not wish-to limit ourselves to the particular employment of the feeding member herein shown, or to any particular conveyer, it is herein illustrated as employed so with a reciprocating or shaking conveyor of the type wherein theconveyer is reciprocated in opposite directions at different speeds, for example, with a slow forward movement and a rapid rearward movement.- 'Referring for example to Figures 1 and 2, A indicates the section on the line 6-6 of 1826. I sem 170. 121,795.;

floor and A the roof of a minetunnel or I passage. A is a transverse passage contain mg for example the tracks A adapted to guide any suitable conveying member or car A". 1

, B is a conveyor trough or chute which mav be reci ers B, which rest upon track members 13 and support the upper track members B upon the trough B.

C diagrammatically illustrates any suitable reciprocating means for said trough, includmg the crank arm C Referring to Figures 2 and 3, we illustrate the trou h B as having secured to the forward en of the forward section of the feeder member be understood that we may employ any suitable number of trough sections 'B, additional. sections being inserted as the work progresses.

The securing means between the feeding member andthe end of the trough B shown in detail in Figures 4, 5 and 6, are asfollows: Secured tothe bottom of the trough B is a reinforcing plate D which terminates at the ends in eye ets or expanded portions D apertured as at D to receive the members D. The members D are shouldered as at D and continue as reduced portions D screw threaded as at D. D are lock nuts, which serve to draw the members D against the rear face or edge of the eyelet D. A

- The feeder member, generally indicated as includes a lower trough E. The feeding member consists preferably of two separate troughs E and E the upper trough E being in slidable relation with the lower trough E, there being-no fixed connection between the trough E plate E sEaced beneath which is the bottom plate Between E- andE may be any suitable spacer or, filler E the assembly and the conveyer section B. At the rear end of the trough Eis a reinforcing procated for example upon the rollgenerally indicated as X. It will be ng bolted together for example by the bolts or rivets E P tom of the trough E and E is any suitable pivot member or pin E- provided with a washer E and a securing pin E Pivotd for rotation about'itin a horizontal plane, andin part contained between the plates E assing through the hotand through the plates E and E is the armfE having at its ends shoulders E be 0nd which outwardly project the cylindrica tions E Pivotedupon each such cylindrical member E is the connecting member D por- 1 which is confined for example by the washer E and the securin pin -E As regards the dc vancing the upper trough E in relation to the lower trough E. We may employ any suitable rack and pinion connection between the two including for example the rack G on one member and the pinion G on the other member and the lever Gr .adapted to control them.

The lower trough E of the feeder is supported upon the ground in the following manner: The member J is a transverse slide or runner which engages the ground and permits easy lateral movement of the feeding member. The trou h E is supported thereupon for example y means of the downwardlv depending members J which are in slidable engagement with the'shoe J. When the feeding member is in anygivenfired po-.. sition the member J serves as a stationary support across which slide the members J Articulating means as employed between the conveyer B and'feeder member X may'be used between the trough sections B as shown 1* in Figure 3.

It will be realized that whereaswe have-described and shown a practical and operative device that nevertheless many changes might be made in the size, shape, number and dispositionof parts without departing from the spirit of our invention. We therefore wish our description and drawings to be 'taken as in a broad sense illustrative and diagramma'tic rather than as limiting us to our spe-- cific showing.

"The use and operation of ourinvention are as follows:

' Reciprocating conveyers of the type herein shown are already known in the art, namely, conveyers which may be reciprocated at different velocities in oppositedirections. in order to cfonvey material fed to them: Such conveyors may be employed for many .pur-

poses and may for example be employed in mining. Such a conveyer when so employed may be advanced from a given location by the insertion of additionalconveyer sections as the shaft is lengthened, all such sections formmg'a single conveyer, reciprocated from a single power source. The material to be conveyed may be shot down from the end of the shaft or otherwise accumulated and is generally divided into lumps and particles of varying size. Upon the forward end of the conveyer is mounted a feeding member which is adapted to be thrust by the forward movement of the conveyer into the pile of material to. be conveyed. The'slow rearward movement of the feeding member conveys away the material received upon it as a result of the rapid forward thrust.

As the face of the material bein fed re- K oedes, the upper trough is advance in relaedi g member" 'roper we may provideany suitable means or ad vertical axes.

tion to the lower, until it has advanced to such a. distance that it is necessary to withdraw it and to insert a new section of the conveyer B. In operating against a laterally extended face, or along a tortuous passage it isimportant that the conveyer as a whole be articulated, and even more important that the feeding member at the end of the conveyer be articulated for free ,lateral movement as well as for movement about a vertical pivot. Thus the entire assembly may be advanced along a crooked passage and up and down various floor levels and the feeding member at the end of the conveyer may be swung laterally to feed from a face of considerable width. We have provided a peculiarly flexible and robust articulating means for the feeder and conveyer assembly herein described and shown. In order to permit the'easy lateral movement of the feeding section we rovide a supporting ground contacting shoe which serves as a runner to support the feeder and to permitit to be swung about a vertical pivot. During the normal operation of conveyer and feeder the feeder, can reciprocate freely in relation to the runner'J, with which it is placed in slidable engagement by means of the downwardly extending -supporting members J We claim: 1., In a self feeding conveyer, a conveyer trough and means for imparting to it a conveying reciprocation, a-feeding member at the end of said trough, an arm. pivoted to said "trough, intermediate its endS for rotation about a generally vertical axis, connectingmembers extending from the ends of said arm to said feeding member'and rotatable about the endsof said arm.

feeding member secured thereto and adapted to move in unison with it and to deliver material direct-1y thereto, said digging member be ing mounted, in relation to said trough, to permit its rotation about both horizontal and 3. Ina- 'self-feedin conveyer, an articulated conveyer troug and means for imparting to it a conveying reciprocation, a feeding member at the receiving end of said trough, an arm (pivoted to said trough, intermediate the en 5 of such arm, for rotation about a generally vertical axis, connecting members extending from the ends of said arm and rotatable thereabout, and afeeding member associated with said connecting members.
