This invention relates to a machine adapted primarily for loading or milling and loading purposes.

The machine forming the subject matter of my present invention is of the general type. disclosed in my prior application. filed January 17th, 1910. Serial No. 538,408. and it in ludes in romhination with some suitahle form of eonvever or material coi'iveyiug means. an operative member in the form of a ram or beam suitably mounted so that it may he given a variety of movements required to convey material expeditiously to the conveying means and suitably constructeu not only-to farl'litate the handling of the material but to adapt this ram fora variety of other purposes incidental to the collection, moving and loading of the Ina-- terial. Further. the invention aims to provide in a maehine of thiseharacter a. ram

Fig. 9 is a side elevation of the outer end of the ram with the tool holder equipped with a relatively fixed hoe or scraper. Fig. 10 is a top plan view of the outer end of the ram showing the tool holder equipped with a modified form of picking tool. Fig. 11 is a side elevation of the outer end of the ram with the tool holder equipped with a shovel, the dotted lines showing the different positions of the shovel and showing a conveyor is also provided with some form of conveyor for conveying material rearwardly from the front end of the machine; and in the drawings I have shown arr-endless belt-conveyor 13 which extends from the front of the mac nerea rweydly. At the-forward end of t go'nveyef'lfi I have provided an in- (dined apron .14, along.-'which themeiyeriel and deposited into a uitagle hopp lfiv arranged-over the forward o t e 3); .w ,Ii h. a" i I Q con-q veyer so that material de osited in the hopper will drop immediate y on the conveyor belt and be carried rearwardly. I have not considered it necessary to show the entire frame or the entire conve er, or more of the details of the apron an parts may have any suitable construction which answers the requirements of such a machine.

The machine is provided at its forward end and above the conveyor with a substantially horizontal supporting member 16 which is supported from both sides of the frame 11, as est shown in F1 3, so as to leave suilicient space between t e support 16 and the upper run of thebelt of the conveyr to permit large lumps of material, such as coal or rock, to be andled by the conveyor without interference by and without engagin this superstructure. Swiveled by a centra king bolt 17 (see Fig. 2), to the horizontal support 16, androtatably supported thereon through the medium of a series of rollers 18 which engage a circu lar track of the support 16 is a turn table 19 upon which is directly or indirectly supported much of the apparatus of the machine, and which is rotated by means hereinafter described about the vertical axis of the king bolt to impart a certain horizontal swinging movement to the ram and to the tool carried thereby.

' provided Extending upwardly from the turn table 19 are suitable brackets and bearings 20 which support a horizontal shaft 20, see Figs. 1 and 3), to which is secured for rocking movement about the horizontal axis of said shaft, a cradle or housing 21. This housing supports a reciprocating telescopic ram 22 composed in this case of an outer box-like member 22 adapted to slide backwardly and forwardly through the housing, and an inner ram member} 22* adapted to telescope with 'or to move in or out of the member 22 as the latter is moved in or out with respect to the housing. The outer member of the ram is sup orted from the housing througn a series at rollers 23 which bear against t e top and Bottom sides of the outer ram member,

with guide rollers 24 which engage the sides of the member22. The outer ram member 22" is provided with a series of rollers 25 which engage the top and bottom sides of'tlte inner ram member 22" and support the same, and also with guide rollcrsi26 which engage the sides of the inner ram member 22 The housi g 21 has a forwardl projecting arm 27', plivided on its lower si c with a rack 28. otatably supported in the upper part of the outer ram member 22 beneath the rack 28 is a inion 29 which engages the rack 28 and a so engages a rack 30 mounted upon the top of the inner ram member 22 below said pinhopper, as these.

' 20' upon which the housin For reciprocating the to escopic ramrel-i. V i

and thehonsing is also ion. By reason of this construction,'when the outer ram member is reciprocated in the housing the pinion is rotated because of its engagement/with the relatively fixed rack 28, and as the rotation of this pinion is transmitted to the rack 30, the inner ram member is at. the same time reciprocated with respect to the outer ram member and the telescoping action is obtained.

For controlling the movements of the ram, I prefer to employ for reasons hereinafter referred to, three separate fluid-pressure reciprocating motors. For swinging the ram horizontally about the vertical axis of the turn table, 1. cm loy a fluid pressure motor 31, which inc udes a cylinder 31 mounted on the turn table and containing a piston (not shown). connectedto a plunger 31". This plunger is attached to a rack 32 (see Figs. 1 and 2) which enga a pinion 33 secured to a short vertical 5 aft, to the lower end of which is secured a larger pinion 34, which engages a section of, a circular rack 35 fixed to the base or so port 16.

or swinging the ram in a vertical plane,

I emplo a motor 36 which includes a cylinder 3d supported upon brackets 37 extendin upwardly from the turn table" 19 (see ig. 3), and a piston (not shown) which is connected to a plunger 36 having at its outer end a. journal box which'receives a wrist pin connected to a air of crank arms 38, (see Fig. 3), secur to the shaft 21 is mounted.

ative to the housing I employ a sure motor 39 comprising a c which is supported upon the and a piston (not shown) co to plunger 39, the'forward end. of which isconnected to the'forwa'rd end of the outer ram member 22'. The motors 31:; 86, and 39 are preferably and exhaust of air from which may controlledby suitable valves properly located with reference to the operator 5 (see Fig. 2), as will fulllyl in connection with Fig. 12. 1

air motors the an 1 to,

i P y 1 station 4 0, .be explained more scribed, the chief of which are speed of ram operation, reversibility, ability to give to the ram reci roosting, horizontally swinging or vertica ly swinging or rockin movements so arately, or a combination 0 movements s multaneous] flexibility in speed and owcr, by whic I am enabled to in) art to t 0 ram through the proper con- I no of the valves fast or slow movements 'short or long strokes and powerful or light i strokes. These advantages enable me to utilize the ram not only for material scrap- 'iiig or collecting purposes, but also for a variety of other purposes, including chipping, picking, hammering or shoveling;-

' all of which functions are of utility, espec- 7 keyed in the socket 4;

. ially for mining purposes, wherein the machine can be utilized for loosening the ma terial, for leveling and truing the floor and walls, for driving wedges and other devices, and for similar pur 0305.

To adapt the mac line for these numerous functions, I provide on the outcr cud of the ram what may be termed a. universal tool head or holder 41, which preferably embodies a forwardly projecting boss ll" and in cylindrical socket or passageway 41" extending through the end of the tool head at right angles to the boss, and provided with a key way 41". This construction is shown mostclearlyjn Figs. 4, 5 and (i.

In Fig. 7 the tool holder is providedwith a picking or ramming tool 42 which is secured to the boss 41 and which is adapted when the rain is thrust forwardly to loosen material.

In Fig. 8, the tool holder is provided with a hammer 43 which is secured in a suitable manner to the boss 41".

In Fi 10, the ram is provided with a pick which is secured to the boss 41 so that the material may be loosened as it would be by an ordinary manually handled pick.

. This pick can be fixed in any angle so as to loosen the matcria'l when the ram is swung vertically, horizontally, or is given a combination of the two movements.

In Fig. 11, the ram is provided with a scoop shovel 45 which is filled by moving the rain forwardly, or simultaneously forwardly and upwardly, and is dum icd by moving the bucket rearwardly. This bucket has digging teeth 45*, at its forward end and is provided with a swinging bottom 45", adapt ed to be dropped or released by a latch 45" operated in any suitable manner. This bucket is held to the tool head of the rain by a U-sha ed device 45 secured to the bucket and liaving an opening for the boss 41' of the head; and having rearwardly extending ears through which and through the 0 iening 41" of the tool head a b'oltor stud 5 passes. p

i In Figs. 1' and 9, I have shown, however, the'principal tool intended to be employed with the ram, this tool consisting of a hoe 46, the function of the hoe being to scrape the material rearwardlv to the conveyor. The hoe 46 may be fixed i'n osition on the end of the rannas shown in *ig. 9, wherein the hoe is secured to a casting 47, which in turn is secured to the tool head by means ,of a bolt 47 which passes through and is of the tool head, and ,is provided at its upper end with a. tightening nut 47". When the ram is provided 1w th at hoe, as shown in Fig. 9, the

.mounted on cylinder 39 of motor 35) and purposes. I th material is scrapcd back onto lhc convcycr by reciprocating tbc hoc shank. and by gii ing it othcr ncccssary mmcmcnts. \\'hcn tin matcrial is located at. one sidc ol' lhc plane of thc-aj'u'on, thc mnlcl'iul may bc inovcd onto the convcycr by filllltlllullt'ulls'l t' moving thc hoc and rain (al'tcr thc lmc llil\ becn sunk into the lllilll'llill) latcrally or tn ward the cculcr line of thc machinc. as wcll as rcaruurdly.

Very ol'tcn. lHHVlYLl'. this construction will not answcr all thc rcquircmcnts l'or otl'ective work, cspccially whcu the machine is intcndcd to work through a wide anglc. and material must bc brought into linc with the machine from the sidestlu-rcol'. lu such event, it may be desirable to scrape a considerable quantity of material from the sidcs of the passagcway madc or clcnrcd by tho loading machine, latcrully to or toward thc center line of tbc machine bct'orc such material is moved rcarwnrdly onto the conveyer, 'l'he cdgc of thc hoe it lived on the end of the ram would not be entirely suitable for this purpose. 1 have thcrcforc provided ac'onstruction which is shown in Figs. 1, 2 and 3 wherein the operator may turn the hoe so as to present substantially the flat. face of the hon tothe matcrial whcn the material is moved laterally toward thc ccntcr line of the machine by swinging the ram laterally. For the purpose of turning thc hoe I provide, reasonably close to the open ators sent; a hand whet-l or cquivalcut turning device 50, conncctcd by a splinc lo a scctional tclcscoping rod or shaft 51 which is supported by suitablc brackets from the ram and housing. The outer end of this shaft is providcd with a worm 522. which cngagcs a worm wheel 53 fixed to thcbolt or spindle 54 to which the casting -li' carrying tho low 46 is fixed. The worm whccl and worm may be supported from the outci' cud of thc rum in any suitable inanncr, but in thiscusl'. I have secured by bolts 55 to thc top face of the universal tool head 41, a standard ms, through which the spindle 54 passes.

Instead of turning the bee by hand 1 may employ a suitably controlled motor for this purpose. In Fig. 3" this is shown in plan view-wherein I employ for adjusting the hoe a fluid pressure motor 50 which is shaft 51 which to the outer rod of the igs. 1 and 2.

connected by gearing 50" to extends forwardlrain as shown in In some instances, it; may be desirable when the hoe is extended a certain distance to hold the reciprocating mechanism against. movement while other movcments are impa t-ted to the ram such as when the rain is used for digging, picking or hammering refore provide a lock for the reoiprocatii g mechanism consisting of a sliding locking bolt 58 upon the top of.

the outer ram section 22' and adapted to be extended between the teeth of the pinion 29 and to lock the same, and hence the entire reciprocating mechanism against movement.

Likewise it may be desirable when the ram has been tilted vertically to a certain,

angle with respect to a horizontal plane to look the tilting mechanism so as to maintain the ram at that angle while other movements may be imparted thereto. I therefore provide a lock for the tilting mechanism, which consists in this case of a toothed so out 57 secured to the shaft 21 upon w ieh the housing is supported, and about which the hammer is tilted, and a pivoted locking arm 58 having a locking nose adapted to be inserted between two adjacent teeth of this segment.

Inasmuehas i-tma be also desirable to swing the ram lateral v to a certain angular position with reference to the vertical plane passing' through the axis of horizontal swinging movement of the ram, and to lock the ram against further lateral swinging movement, I have provided for this purpose a locking means which inthis case consists of a pair of arms or latches 60, (best shown 2), which latches are suitably sup-' in Fi parted with reference to the rack 32 so that the nose of one or the other of said latches may be inserted between any two of the teeth of the rack to hold the rack against further reciprocating movement, and to prevent rotation of the pinion 33. I have provided two such latches so that the rack may belocked movement regardless of its position with reference to the cylinder of the corresponding motor.

In order that the machine may be utili red for the various purposes referred to, and in orderthatthe ram may have the functions above described, it is of course essential til at the ram be capable not 0111 of being thrust laterally outwardly, inwa l downwardly, or upwardly b the several motors, but the ram must stresses,

in horizontal and vertical planes, incident to the shocks which would result from hammering, picking and other operation, and from drivngg or sinking the 1100 into amass ofmateri preparatory to uioving it onto the conveyor. This is provided b oonstru'ting and supporting the a tram so at it will be capable of successively it {resisting any of the stresses, to which the be subjected in the use of the ram. may

machine. I

I have previously mentioned the fact that the machmeior successfully performing the funotionidor which it is intended. should he so constructed and operated that a combiha'tio'n "of separate movements could be imparted to the ram sultaneously. That this characteristic is esirable if speed of operation and good results are to be obbe capable of successfully resist,

hot

tained is apparent when it'is considered that the operator is thereby enabled to move the hoe outwardly and simultaneously elevate the same or simultaneously outwardly, upwardly and laterally. Thence when the hoe has been Sllillk int? a mass of material by 'ving the as i necemy, a quic sha-r p downward thrust, material can be moved back onto the conveyer by moving the hoe rearwardly or simultaneously rearwardly and laterally (in the event that the material is at one side of the machine) and at the same time force can be exerted downwardly on the use by admittin the -right"pressure of ainii the rear 0' the piston of the motor iitilized in elevatin the hoe, to prevent the lies being elevate or by itself shifting upwardly, as the heavy mass of material is drawn rearwardly. The desirability of simultaneously applying two movements to the hoe, or of applying, power to the ram through two cylinders, is olearlyillustrated while the hoe is in the act of drawing a mass of material to the conveyor. In case a mass of material is being drawn by the hoe, say along the floor of the mine, or along any surface,

one movement could be imparted to the hoe at one time, it would be necessary for the operator to stop the rearward movement before moving t a hoe over the obstruction, then move the hoe rearwardly again, thence stopit, thence lower the hoe, and thence again continue the rearward movement.

At this point it ma be well to describe an important detail 0 my invention, which is ofarticular utility when the machine is use in a mine where it is desirable that the mine floor be left by the hoe in even or flat conditione This feature which I have just referred to consists of an arran ment by which the hoe is caused to trave rearwardly, in inovin material onto the conveyer, in a straig t line, and is prevented from. leaving the floor in an uneven conditlon by being de ressed more than a certain amount and cutting into the floor level. It will be seen by reference particularlyto Ff gs. 1 and 2, that the rear part 6f the outer ram member 22 is provided with a roller 62, and that the hous" is this roller with a eurv 1ngle1nember 63, which serves as a ide'for the roller and as means for control mg the path of movement of the bottom of t e hoe, as the same is provided above her 72 air may be conveyed throu moved rearwardly. The curve of the memher 63 is such that as the hue is mo ed rearwardly, its downward inclination is increased at the proper rate to cause tllia bottom edge of the hoe to move in a straight ine and to pron-ulit from being depressed beyond said straight line. When the hoe reaches the forward end of the apron, the roller passes beyond the member 63 and thence moves in a straight line, inasmuch as the hoe is constrained to thence move in a direction parallel to the and just out of contact therewith, the lee then being tilted downwardly the maximuiii amount in motor. The turn table is also prefera y provided with an L-shaped track 64 which is engaged by the roller (32, when the ram and hoe arm are moved rearward] with the ram elevatml. This guide trac 64 gradually decreases the inclination of the ram as it is moved rearwardly, and thus prevents the rear end of the ram colliding with the turn table.

Reference is now had to Fig. 12, wherein I have illustrated diagrammatically a system ofcontrol by which the variable characteristics of speed, power and length of stroke may be obtained. As before stated, I utilize fluid plressure reciprocating motors, preferably}, owever, air motors. Assuming that air isa motive fluid, the air der s -'table pressure through a su ply pipe W11 ch is connected by piping esignated asa whole by the reference figure 71 to three four-way valves 72, 73 and 74 one of which is associated with each of the three fluid pressure inbtors, 31, 36 and 39, and is adapt ed to control the application of power to that motor, and hence to control the speed, power and length of stroke imparted to the ram by means of such motor. The fourwa valve 72'has an operative handle 72', an in addition to the inlet pipe connection 5 an exhaus pipe 72", and has also connected to it two air conveying pipes 72 and 72 which are connected to the cylinder of motor 31 near the ends of said cylinder. By properly manipulating the valve mall]:- t B pipe 72 to the rear of the iston 0 motor 31, and exhausted or our: away from the forward and of the motor said piston) through the pipe 72, so as to drive the piston. forwardl or air may be supplied through the pipe 2 and exhausted through thopipe 72, and exhaust pipe 72", so as to drive the piston rcarwardly. In a similar manner four-way valve 73 has an operatin'g handle 73*, an exhaust pipe 73 and two air conve. ing pipes 73 and 73 which are connected to the cylinder of motor 36, and four-way valve 7 4 has an operating handle-74 and exhaust pipe 74! and ylng p1peg74" and 74, which face of the apro permitted by the stroke of the tiltis supplied un- (in advance of are connected to the cylinder ol motor 39 near the forward and rear ends thereof.

\Vith this system of control employed in connection with the fluid pressure l((l[)I0 cating motors, not only is there llexihlo speed and power obtainable. and not only can different movements he imparted lo the ram simultaneously, and variable degrees of power applied thereto at one or a plurality, of points, but I am enabled to stop and start any ram movement or reverse the movement of the ram very quickly.
