Be it known that I *Warren Tueur, a citizen of the Uniteil States, resicling at Reno, in the county of 'Washoe and State of V da, hay@ invented, certain newanfl useful linproveniente in llfueking rpparatus, of which the following is a specification.

The present invention relates to en ai paratus :for following `the drilling or blasting operation in, the driving of a gninevor railway tuxlnel, the purpose thereof being to "remove the debris or loose soil broken down within the tunnel by the operators in advance thereof; the object of the invention being the oreduetie of a Simple, efficient? en@ durable meehil. fer suessfully removipg the soil an4 rook displaced by the drilling and blasting operation, a machine which will' handle a' large tonnage per day, and one which will dispense with the einployment olf a large force or 'Working crew of mee et' Present l'eeure 'be' remi/ine such material from within the tunnel as the work therein. progresses, the machine beieg 'of suoli e obere-eter es. not .only to remore the loose or ellingmaterial, but at the same time leave the .interior Well sei'- faee of the tunnel-in a substantially lin ishecl eoinltiogi.

In general, the apparatus. comprises a suitable supporting structure, a rotatable leliyjery cylinder or tube mounted thereon, a spiral scoop for elevating the loosened material and discharging' the saine into.tbe

deliyery cylinder, mechanism for propelling the supporting structure and, imparting rotation "no, the delivery Icyli2 yder or tube, and Ineansfor controlling `the Ilongitudinal feed of the seid cylinder or tube.

Fig'. 5 is an enlarged detail View of the look nut for enraging 'with the threads of the rotatable cylinder or 'tube for lcausing.T longitudinal travel thereof relativo to tlie'supporting structure, said nut being' illustrated in e11- genienb with the outer threads of the Cylin- :eler or tube, which is partly broken away.v

ln the'lrewings7V the vnumeral l. is used to designate any suitable form of a supporting raineoapable of sustaining the working parte of the apparatus, the saine being supported by the forward Whees` and, the rear wheels 2', mounted respectively on the forward axle 3 and rear axle 3. From the supporting frame or bed l upwardly springs or feed opening B. The scoopl 7 which' is fastened to the forward end of the cylinder or lube serves as a laterally promoted auger yfor cutting, oleif'ating'and discharging the material to be removed from within the tunnel into the cylinder or tube 5, the size of the soooy; from the airis oil' the said oyliniler or tube 5 to its exirei'lie cutting or shovel elige of its shovel extension S being ap iroximately one-hall the diameter of the iunufel lo be formed, so that with eaoh revolution of the .cylinder or tube 5 the scoop 7 Wil] travel approximately the oirmunferenoe of the tunnel, the cutting or shovel edge of its shoyel extension acting close to the oom- ,pleteyvall' of the tunnel. As ,rotation is imparterl to the eylinderor tube 5, the spiral scoop or shovel?" picks up the vloosened material in aduanas thereof and discharges the saine into the cylinder or tube 5, Where the material is acted on by the spiral rib 9 therein which seryes as worm. for forcing the reoeiyeei materiel through the 4cylinder or Alube and clisehar .ing the same at the rear thereof, delivers the material into .ce e Seeed e e@ wir en@ eee apeeielue le .receive ilie'eelel 'lhe apyaratus' as a Whole moves within .the teveel ee Sile-porties tracks 1'0 Placed lrierem to ;eoeiy e"the saine; which tracks or rails are extended 'Wit iin the tunnel as the work therein advances, and the ap paratus is held securely in place within the tunnel duringjY the longitudinal or feed movement of the rotating` eylinder or tube 5 by means of the -jaelts 11 and 1l which are supported b y the pillar bloelts -l and 4 and adjusted to bear against the root. of the tunnel beingy formed. .lt may be desirable at times to throw the nut out oll engagement with the spiral serew threads, aml rotate tbe. cylinder or tube 5 independently of any longitudinal movement thereot' rela- 'tivewtoy the frame, and as the material is removed Vto advance the entire machine as t'ar as the tracks extend and when this point is raehed to tln'ow the nut into e|. ,'a ;'e ment wit-h the spiral serew threads and advance the tube simultaneously with the rotation thereot. ll'hen it is desired to l'orwardly advance the supporting frame or structure after the rotatable cylinder or tube has` moved forwardly its t'ull distant-e in advance thereof, and then screwed bark to its normal starting' position, in order to position the spiralshovel t'or a new aretion ol work, the jaelts ll and llI are .serewed down and the entire apparatuf.- moyed tor- `wardly within the tuum-l a dishuieeietpial to the projectionI of the rotatableA u vlinder or tube beyond the same. the 'iai-lts being; then screwed up to hold the z`|pp.\ratu:-l loelied in said posit ion.

The apparatus is operated by any icuii able type of a reversible motor or engintl 12, iu the present ease an eleetrie motor bei e' elnpload, the power ot' which is transmitted to a drive shaftl 12 by a ehain lll Working; over a sprocket wheel 125 on the motor shaft aud a. sproeket wheel l-t on the drive shaft 12. 'lhe rotation ol. theI drive Shaft is transmitted to the rear axle 25 ot' the suliporting structure in any suitable manner, as, for instance, by a drive chain 14 Working over a sprocket. wheel 15 of tlie rear axle 3 and a sprocket Wheel 15 loose on. the drive shaft 12', the said sprocket wheel l5 beinethrown into and out of locked engagement with the drive shaft 12 by means of the aetuating fric tionclutch 16, thrown .into engagement with the hub thereof .by a hand controlled lever 16 extended to a point within con-- venient reaeh of the operator of the machine. y

In addition to the sproehet 15 loose on the drive shaft. IZ, there is loosely mounted thereon a worm t7, in mesh with the, worm gear ring 17 though which the rotatable cylinder or tube 5 extends, being feathered thereto. The hub 1S ol.' the worm 17 is engaged by a t'rietion elnteh IS Secured to the drive shaft for imparting,r motion or rotation thereto :for driving.; the. eylinder or tube 5, the said eluteh being controlled by a hand actuated lever 19 extended to within eonvenient reaeh of the o erator of the machine. ln this manner t e power of the aetnating niotor is transmitted for imparting rotation to the cylinder or tube 5, the direction of its rotation depending u on the fotary motion transmitted to the rive'shaft.

For imparting forward and rearward longitudinal movement to the rotatable cylinder or tube 5, depending upon the direction ot' rotation imparted to the drive shaft 12. the said 4eylinder or tube is provided with the external se1'e\\'-threads 119', for its t'rrll length, whirh are engaged b v the internally threaded segmental nut 20, pivotall v mounted as at 20 between `suitable ears 20;' extending upwardly from one of the pillar blocks` say 4. When the said nut is in mesh with the external threads 0f the cylinder or tube 5, a longitudinal feed move ment is imparted to said cylinder or tube during the. rotary movement thereof, which longitudinal movement ceases the moment the feed nut Q0 is thrown out of engagement with the external threads of the cylinder or tubo 5. 'lhe forward movement of the said erlinder or tube is regulated in aeeordanee with the work of removing.;` the loose soi! or debrisI within the tmmel in advauee thereof, the same being held against t'orward l'eed until the spiral seoop has taken up the dirt to the extent ot its full width and t'ormed a eleau inner wall to the tunnel during the rotary movement thereot'. the eylinder or tube being then ad- \.aueed forward :mother step by throwing the.v l'eed nut into engagementtherewith, sueh istep leed eontinuine' until the cylinder or tube ."1 has moved outwardly its tull dis-laure. and the tunnel cleaned to sut-h a point. ly then reversing' the drive. motor, au inni-rrd longitudinal tred will be transmitted to the cylinder or tube 5, provided the feed nntbe thrown into engagement. with the external threads thereot'` to toreo the sanne itI t'ull inward distanrtnat whieh time the t'eed nut is moved out ot` loehed engagement therewith and the elutrh lo" diseonueettal from the hub 1S of the worm 17. The reversing: eontroller l'or the motor is then thrown to impart forward travel to the structure, the. lever VltS being op erated to place the. eluteh 1G into engagement with the hub of the sproelietwheel 15', thus forwardly ai'lva'neing the strut-ture the desired distance, when the eluteh 16 is thrown out olengagement with the sproeltet wheel 15 and the eluteh vltthrown to eonneet'. the worm 1T to the drive shaft 12 `t'or imparting;` rotation to the Cylinder or tube. 5 and the `spiral shovel 7 carried thereby. l

Il v the use ol' the dteribed apparatus the worh olI removing the loose material from within the tunnel is in keeping with the albanre worh ot' drillingand blasting, leaving the same in-a finished condition. As the car 9 located at the rear end of-f cylinder 5 becomes filled with material, the same is removed and an empty car placed beneath the discharge end of the cylinder 5.

I am aware that various changes may be made in the construction of the various Working parts of the described apparatus without creating a departure from the in-v raising material and dischargino' the same' therein, devices actuated by the rive mechanism for imparting rotation to the rotatable tube and the scoop carried thereby, and independentl operated .means for imparting lon` gitndina movement to the said tube during the rotary motion thereof.
