For the driving connection of, these four shafts in the manner shown in of the drawings, four casing heads are' providedto protect the gears and 2G I mayv rotate bodily together with its bevel gears hold them in engagement. The outer sides of the blocks 25 which in a horizontal plane, are rectangular in form, are provided with vertically extending flanges 27 upon which the upper casing heads 28' are mounted. 'Within the lower portion of each casing 28 are, located the beveled gears 29 carried by said vertical, telescopic shafts 30.

In the lower casings 28, the inner faces" of the same 'engage'the peripheral flanges '41 of the casing 42 which protects 'the shaftr83, as

shown in Fig. 5. From this description, it will be seen that each of the telescopic shafts 3O 29 without interrupting movement of the boom lengthwise of'the machine. The shafts 30 are shown in'their closed relation in Figs. 1, 3 and .5; 'while'theyare shown in'their extended relation in Fig. 2 while the boomis raised and I shifted forwardly. The icasing 42 is divided into two tubes, two .cup members 43 being riveted to the-casing sections and to each other. Within this intermediate casing 43 a worm gear 45 is mounted on the shaft 38 for rotation therewith, and a worm shaft "46 enters the casing and engages the gear 45] for driving the excavating chains, and is itself driven from; the main powershaft 47 by gear 48. 'A very important feature of my combined'ma chine is the provision of a conveyor just underneath the upper endof the excavating or digger unit,.and so mounted that it may be .swung about avertical axis by power means, material at different positions to deliver the desired.

7 It is characteristic of the conveyer mechanism disclosed in this application that'such conveyer 68 may be swung outside the outline of the ma-'- chine, and in an'arc'extending over l8il degrees or somewhat more, depending upon thecharac ter. of the surface of the ground where the conveyer may deposit such material. Such mounting of the conveyer comprises actuating means for the movement of the conveyer unit about its vertical and, further, power-driven means for actuating the conveyer belt itself, and suchmounting will nowbe described.

Within a fixed casing '58, suitable to enclose a cylindrical hollow casing 59, I enclose driving Worm gearing, and shown in vertical section in Fig. '6. The said verticalcasing 59 may rotate upon suitable bearings 60, and has mounted thereon for its actuation a worm gear 61 engaged by the driving worm 62 mounted on the horizontal drive shaft 63 which protrudes through the casing 58 .and is slidably and non-rotatably en'- gaged with the worm 62 by polygonal form of the shaft in cross-section or by keying, to prevent relative rotation of the shaft and worm. Integral with the casing :59 is anupper enlarged hollow gear casing64, preferably rectangularin outline in cross section but somewhat elongated fin a direction lengthwise, of the belt.

Mounted on said casing 64 and rising "there-1:

from in-an upward andrearward di'rectionare provided frame arms 65jwhose upperends are widely spaced and have bearings thereon66 for receiving therein a horizontal drive shaft 67 members 71 are pivoted to the casing 64 in suit-- able manner with the upper ends'thereof 'positioned just outside of the frame 680:1 either side thereof, and adapted to engage, interchangeably,

' a bolt or pin on the members 68 to adjust the desired height of the conveyer on its pivot 67.

Suitable means may be provided for locking the brace members in. their adjusted inclination.

The belt element 69 is driven from the roll '70 carried on the shaft 67, the latter having on-its ends outside the arms 65, suitable sprockets-.72.

A driving shaft 73 passesthrough the gear 'c'asing 64 parallellto'shaft 67 and mounted upon the side walls 74 of casing 64 in bearings therein. Sprockets '72 similar to those on shaft 67 are mounted in alinement with their corresponding gears and sprocket chains 75 at either side engage the respective sprockets.

By the structure above described, the rotation of shaft 63 may drive the casings 59-and 64 together with their supported conveyer structure 68, about the axis of the vertical casing 59, while the. conveyer belt .69'may be actuated from shaft '73 while the conveyer is in any position upon said axis. For driving the shaft 73, a vertical shaft 76 is'mounted within and longitudinally of the casing 59, being provided with sleevemembers 7'7 engaging the ends 78 interiorly of the casing 59, to make proper rotation therein. Both ends of the shaft '76 are provided with bevel gears '79, the upper one of which engages a bevel gear 80 secured to the shaftf'ZB within the gear cas ing 64. A similar bevelgear 80 is mounted upon a horizontal shaft 81 for engaging. ear 79 below the casing 59, so that rotationof shaft-81j will drive theconveyer belt 69.- g

The sleeves'7'7 of the shaft '76 rotate upon suitable bearings 82 upon the ends of the casing 59, so that the parts 59 and 76 are independently V rotatable, the latter driving the conveyer belt," while the former adjusts the conveyer in its relative position about the axis of the shaft'76. The shaft 63 is elongated for quite an extent and is slidably movable through the worm 62- whereby the shaft is immovable lengthwise of the frame, but rotatable to drive the worm-, while the entire conveyer mechanism with its gearing and casings 58, 59 and 64,, are movable longtiudinally of the machine as the-worm '62 slides along the fixed shaft 63, these arrangements of relative parts serving an important function to be described now in further detail.

It should be noted, however, that the shaft 81 is carried lengthwiseo'f the frame togetherwith the bevel gearSG, another portion of theshaft 81 sliding through an element for driving thev same rotatably. I

While the casing 58 has been referred to as fixed, in describing ,the parts mounted within.

the same, suchterm' is intended to'be used in the sense of being fixed relative to the rotating .parts, within. Because of a the arrangement of the boom and its chain digger mechanismltherej onfor movement longitudinal of the machine, ithas been found necessary that the casing 58,

together with allparts carriedpthereby; shall be =.-mounted for corresponding longitudinal i movement in parallelism with thedirection I of a movement in which .theboom travels, to insure vertical Ialinement of the, upper end of the chain digger mechanism for depositing the excavated material, :and the approximate point above the axisofithe parts 59 and 76.; The structure for" causing such movement of the conveyermecha- ;nismwbodilyforward will nowxbe described." Mounted forwardfof the braces and the casingsf58, .59 and 64,; are frame braces5 upon: which'the forward ends of the Ls 50 and plates" 5l; are mounted,=.the rear endsofsuch Us and 5;;plates being ,mounted securely upon, the. long bracesilO, in, thetman'ner indicated i in Fig.

5 of the drawings. Between the rearwardposition of the plate orbar 49which is shown in Fig. 5 of the drawings, andcarries the casing.

43 and drive" gearing forthe shafts 30, and the forward braces ,5, the casing" 58 is mountedupon' said Ls50 and plates 51 forreciprocatingimovee ment, thereon longitudinally of ;.the machine.

The-casing ,58 I is carried by vertical bars-s83 which maybe .L-bars. connected together by flat plates. 84* bolted'or. riveted thereto, the cas-. ing58 being ,directly mounted between saidplates '84 which .are'suitably spaced'to receive it,: as shown' ingFighiln i a v To. the upper ends of the bars 83. are secured outwardly-directed blockscor plates 85,

asshown'inFig. 8 and of proper size and proportions to. fit thespace between the --Ls 50.

whereby the casing58 and its mounting may "readily travel lengthwise of 'the. machine; Suitable inclined braces86 connect the bars83- and thewplates 84 for the .purpose .of. great rigidity.

The casing .58 is provided-at its :lower position witha downwardlyaextending. arm 87 perforated lua'to receive therein .thefshaft 81,' as shown in Fig-n1. To said'arm 87 thereis fixed a link 88- extending1,.rearwardly .andconnected with actuating means for ,reciprocatingthe conveyer in the-track just'described.

lower or operative position in the trench," the 1ink::20 is substantially in horizontal, lposition, asashown in Fig. 1. This. position is' further shown in Fig. 7. Theflink, 88. is then substan 503: tially parallel with link 20.I A lever bar 89: is

pivoted to a part190-of the base, and the upper 'end ,of bar '89 is then pivoted toothe rear end of the actuating, link88; so thatswinging the lever-bar 89'on its pivot'will reciprocate ith'e 5,5xfcasing 58v along the parts 50 and 51, and as a result, when the digger mechanism'lf) moves toward or from the trench being dug, the long.

link 20 will move on its pivot'23,'. and the casing 585964, together with the conveyer supfi i ported thereby, will be moved bodily lengthwise of the machine to cause the position of the conveyer to remain beneath the delivery end of the endless chain digger.

It is to be noted that the parts 20 and 89 are not connected directly together, though the former operates the latter; Instead, an inclined link or brace 91 connects the two, so that 1 the fulcrum of the bar 89 may remain constant in position, while the digger boom is swinging the bar 89 and thence the casing 58. The movement of the latter, which carries with it the conveyer itself as well as its actuating mechanism, is guided positively by the horizontal travel of the blocks in the tracks resulting from the Us 50 and plates 51. j Thetravel is in the apron 69.

This latter actuation of the" conveyer apron 69 may be attained when the conveyerunit is adjusted toany one of its relative positions about theaxis of shaft76.

The connection of the boom 14 withthe conveyer unit 69 by the link system shown in Fig. 7 of the drawings, makes the mutual movement of the tWo elements very positive and certain,

so that the point upon the apron 69 directly' above the shaft '76 will remain substantially beneath the upper end of the digger unit 15 jdur-' ing the position of the lower end of the unit 15 in the trench. Some time after the said lower end of the unit 15 has moved out of the trench, a 'point willbe reached where the shaft 24 has moved forwardin the machine faster than the vertical shaft 76 0f the conveyer mech:

anism has been advanced. by its connection with I position aslshown in Fig. 2 is to provideia practical position which may be used, though not especially over highways, one means for .moving thefboom;

.- downwardly andrearwardly to the operative pomounted longitudinally of'said' main frame, one v the link 26, but it is now immaterial what the relative position of the two units 15 and 69 is, since the unit 15 is no longer carrying material from the trench, and hence is not delivering ,anything at points beneaththe shaft 24. When, .however, the rear end of the digger unit 15 is again lowered as far as or below the ground surface, the shaft 24 will have ,moved back to a position above the conveyer unit 69 as before. a The purpose of holding the boom in horizontal transportation,

essential, for

sition, includes the winding reels 52 which. are

unwound when the unit 15 sinks downwardly. Thus the two units 15 and 69 are actuated to-' gether from a common source of power, but they are adjusted together in proper relative posi% tion while it is essential that they should be, when; the unit 15 is of the structural form shown in these drawings.
