Fig. 17 is a plan view of the control valves shown in Fig. 16.

Fig. 18 is a horizontal section of the control valve for the vertical jack whereby the free or delivery end of the conveyer is raised and lowered.

The construction shown in said drawings is substantially as follows The frame of the conveyer comprises two sections,namely, a rigid section 1 which may be mounted upon any suitable stationary or movable support, and a horizontally swinging section 2. Each of said sections is a box like structure; said section 1 has a floor 3 and a deck 4 which are united at their ed es by means of the side channels 5, 5; side anges 6, 6 are also supplied. Section 2 comprises a floor 7 and a deck 8 which deck and floor are united at their lateral edges by means of the side channels 9, 9; side flanges 10, 10 are also supplied, all of said members being structural steel elements.

Said sections 1 and 2 are united by means of articulations consisting of the two hinge structures shown in Figs. 8 and 9, 10 and 11 respectively.

The Fig. 8 structure is attached to the under side of and unites the deck plates 4 and 8'; the base member 11 is secured to the deck plate 4 and the wing member 12 is attached to the deck plate 8; the pivotal point and member of said two members 11 and 12 is indicated by the ordinal 13.

' the wing member 15 is attached to floor plate 7 the pivotal point and member of said Fig.

- 10 structure is indicated by the ordinal 16.

' Said tpivotal points 13 and 16 are accurately vertically as shownand indicated in grooved pulle sections, about which pass the actuating cab es whereby section 2 of the elevator frame is caused to swing radially; the junctional or abutting ends of the deck and floor plates 3 and 4 are laterally widened to conform to the area that is swe t over by the flexible flan es 19 and 20 w en section 2 is caused to swlng laterally to its respective limits of travel.

Said section 2 is actuated to its various positions of radial swing by means of the following described equipment and in the following manner:

Upon each side of said section 1 is mounted a hydraulic ' ack 21 and 22 each of which is provided with a plunger 23, 24 respectively, also a breech 25, 26; a alloy 27 and 28 is mounted in the respective reaches; pulleys 29, 30 are also mounted in the outer end of the respective plungers 23 and 24; the breech blocks 25 and 26 are each provided with a cable eye 31, 32 respectively, for the attachmentofthe respective actuating cables 33 34. One end of each cable 33, 34 is attached to the eye of its respective jack and from thence it is passed around the plunger pulley 29, 30, thence around the guide pulley 27, 28 of said jack, thence around its respective pulley sector 18, 18 of the hinge member 12 and firmly secured to said member 12.

For the purpose of actuating said jacks a pump and fluid control organization is provided comprising the following members .which are shown especiall in Figs. 15 to 18.

A supply of fluid-pre erably oil -is carried in a tank or reservoir 35 into which is connected the suction ipe 36 of any suitable pressure pump 37. he discharge pipe of said )ump is referably divided into two branc es 38 an 39; branch 38 leads to a control valve 40 whereby the fluid is controlled and selectively directed to and released from. From an inspection cither jack 21 or 22. of Fig. 15 it will be noted that said valve 40 is supplied with two outlet pipes one of which, 44, leads into jack 21, and the other pipe leads into jack 22. In said Fig. 15 the plug 43 of said valve is shown as being set for the direction of fluid through theflexible pipe 44 into the jack cylinder 21, and for the discharge of fluid from the jack cylinder 22 through the flexible pipe 45 mto valve 40 and from thence into the by-pass pipe 46 which communicates with the suction pipe 36 of the pump. By imparting to said. lug 43 substantially a quarter of a turn the uid.

directing conditions above set forth ma be relatively reversed as to the jacks 21 an 22, whereby the sweep of section 2 of the conveyer may be caused and determined both as to direction and extent, at will. By placing said plug 43 in a position intermediate the two positions just specified, or so that the duct 46 will be in registry with duct 48, the pump 37 may operate continuously and the actuatedfluid Wlll be by-passed through the by-pass 46 and pipe 46 into the suction pipe 36.

A description of the valve 47 and its function will be presently given.

Referring now to the scraper chain which actuates material along the decks -4 and 8, the members which make up an assembly unit of said chain are shown in the assembled relation in Fig. 12 and separately in Figs. 13. and 14.

Said chain comprises a sprocket link 48 having laterally extendingarms or scrapers 49, also a sprocket link 50 which does not have the scrapers; said links 48 and 50 are provided at each end and upon each side with hooks 51, 51, for engagement with the eyes 52 of the connecting plates 53: Said arms 49 have an over-all length which is substantially equal to the Width between the flanges 6-6 or 10-10 of the conveyer, and they are pro vided at their outer extremities with a roller 54 which may contact with the inner, adjacent, vertical face of the respective flange at the side of the deck, and when the conveyer is in the flexed position at either side of the longitudinal center line said rollers upon the corresponding ends of scrapers 49 bear heavily upon the inner face of the right hand flange 19 if the conveyer is flexed toward the right, or the inner face of the left hand flange 20 if the conveyer is flexed toward the left, as shown in Fig. 1. The flanges 19 and 20 are, as previously stated, laterally flexible and are rigidly secured to the flanges 6 at the points 55, but the other end of said flanges 19 and 20 are provided at 56 with aslip joint for the-par ose of providing for the difference in lengt caused by the longer and shorter radii of the respective sides in various conditions of flexure.

The conveyer chain is driven by the sprocket 57 Fig. 3, which is keyed to the shaft 58; said shaft 58 is directly connected and driven'by the shaft 59 of the speed reducing unit 60; said unit 60 is driven by an electric motor 61; the shaft of pump 37 is directly connected to the shaft of said motor.

As shown in Fig. 4 a plain roller or pulley 62 is provided at the free end of the conveyer ably over which the conveyer chain travels; said roller 62 is loosely, revolubly mounted upon a shaft 63 which is adapted to have motion longitudinally of the frame 2- and in such a manner that it may not only have a ,considerable degree of flexibility and movement responsive to severe tension upon the conveyer chain, but may also automatically act as a take-up whereby said chain may be kept.

taut in case of wear between the members of the links thereof. Said flexibility and auto.- matic take-up action is secured in the following manner: a shaft 64 has an end which is reduced in diameter, and this shaft is introduced through an adjusting screw 65 and through a compression spring 66 with its reduced end occupying an eye 67 in the outer.

- desired amount of pressure upon said shaft 67 and at the same time said shaft is yieldresponsive to undue tension upon the chain;

The receiving end of the conveyer is hung upon shaft 58, the outer end of which shaft is provided with an outboard bearing 69. A hydraulic jack 70 also supports section 1 of said conveyer, whereby the free end of said conveyer may be adjusted vertically.

The breech of said jack is provided with a fluid inlet 71, to which is attached a flexible pipe leading from the outlet 72 of the control valve 47. This valve is shown in transverse section in Fig. 18 and from an inspection of said figure the operation of said valve will be readily understood; its principle of operation is substantially the same as that of valve 40.

Many modifications of most of the details described in the foregoing specification may be made as desired, and as illustrations of such modifications, the conveyer chain may consist of links as 48 and plates 53; .the jack 70 may ormay not be employed; a sector shaped rack and a cooperating pinion provided with suitable manually operative means may be substituted for the jacks 21 and 22. i
