To all avhomia't may Be it knowm that we, Fmn Brnmn'os and Rmarzrr P. Gnnnmr, citizens of the Unied Stwtm, and residents, respectively, I of Cleveland, in the county of Cuyaboga and State of Ohio, and Cleveland, in the county of Gnyahoga and State oi Ohio, have invented a certain new and useful Implacement in Loadi Machines, of which 10 tollowing' a 111 clear, and exact deso w 1011.

i invention relates to a loading maoh'ne adapted particularly ior use in mines wine --the head room is limited.

)5 The principal object of the invention is to provide an improved type ot machine which is'cfieient for loeding loosened material into dump cars.

More specifically considered, the inven- 20 tionmims to provide a machine of the type wherein a ial moving or conveying element such BS a shovel or hawlmt is filled by 'ining thrust forwandly into the material andis then elevated and swung rearmdly 35 so that the mutants may be dumped into can or other receivin means at the near of {he-machine, and it is one of the particular objects toaccomplish this by a machine whlreiu the shovel or conveying element .is

an filled by direct forwardthrust, and when swung rearwardly over the machine to discharge meter-ill at the rear theneof, it will not at guy point of its cycle of movement extend above the mine floor a suflicient dis- 85 tome to strike the overhead walls or timbering.

These results are accomplished by the present invention which may be briefly sumas consisting in certain novel details of construction and combinations and arts of parts whch -will be described .4. specification and set forth in the ac- W avin claims.

- In the mom nying sheets of drawings, Figure'l is e si e e ovation of the improved machine with the shovel shown by full lines at-the beginning of its toward stroke, and by dotted lines at the endo'f its rearward strdke;Fig: 2 is a plan view of the same; Fig; 8 is a transverse sectional view substentially aleng the line 3-3 of Fi 1; Fig. 1"is a transverse sectional view the h urge! art of the machine substantially a gthe Pine 4--4 of Fig. 1; Fig. 5isasi elevation similarto Fig. (1 one reduced Emile but with the ram extended, end with the bucket at the end of. its. forward dimltepand Fig. 6 is a side view of a portion of the machine showing a slight modification.

Referring now to the drawing, 10 nepresents a wheeled frame or truck adapted to run along a track indicotedat 14L truck 10 18 mounted a platform or turntable 12 whiehcan be turned horizontally through a predetermined are about a vertical Amie, the truck in this case having ensued. men which are engaged by a. front nnller b3 and rear rollers 14.

)n this turntable 12 iswppontedthelmenhamsm for handling materiel, that is, for shoveling it up within a given angle in front of and to both a'dos oitheanachineand conveyin it rem'wairdly over the and final y discharging it into suitableoum', n portion ofione ofwhich isindimted-It 15 in Fig. 1. This mechanism in this ease includes a single motor, a telescopic ram adapted to bereeiprocated or slidfonnqrdky and real-weirdly, a material moving clement preferably a shovel, and telescopic armsconnecting the shovel to the outer or more mp- 1dly moving pazt of the ranyto her devices so arranged that the vel while passing through a complete cycle of J1mement is thrnstiorwardly the gonad level so as'to'he filled with ll h land-is then retracted and when brought up to a point near the front end of themmhine is swung upwardly and. manwamdly so that the material will be discharged. into the at at the rear and then will he again swung forwardly and downwardly to its position. 1

Inthe embodimentof our invention hone shown, we employ for the purpose above stated, a horizontal motoriof the reciprocating fluid pressure type, air being I eferably employed as the motive flui this motor including a e linder 16, with a piston or plunger indicated at '17, (,see particularly Fig. 2). At end this plunger is connected to one 18 of the mm, which as here shown is :U shaped and includes a front emespieoe or cross head 19 endtwo side members .90, 20, which extend rmrwardzly alongide the motor cylinder-'16, This rem member re mcafes in suitable supporting and tgu' log members comprising forward and rear rollers 21, which engage the top and bottom sides of the rearwardly extending ram members 20. .The ram includes in addition to the inner ram member 18, an outer ram member consisting of two straight bars 22,

which are parallel to and are on the outside of the members 20 of ram member 18. The bars composing "the outer ram member are supported and ided for reciprocating movement by rollers 23 which engage the top and bottom sides 'ofthe bars 22, these rollers being journaled on castings 24 which are secured to the side bars 20 of the inner ram member. 'It might be here mentioned ing of pinions 25 carried by the side bars of the inner ram member, each of these pinions engaging a fixed rack 26 carried by the cylinder of the motor, and a movable rack 27 carried by one of the side bars of the outer ram member. 1

While We have shown a telescopic ram, a straight single member ram may be employed.

a The ram actuates a shovel or bucket 28, here shown as substantially triangular shaped in cross-section and provided with an open front and preferably with a digging portion 29 at its lower front end, as shown in Fig. 1. This shovel is connected to the bars 22 of the outer ram member by two arms, each composed of telescoping parts 30 and 31, the former being connected to the sides of the shoveL and the latter being journaled on studs 32 of castings 33, secured to the bars 22 of the outer ram member. The two parts 30 and 31 of each arm have a sliding connection with each other, the part 31 having a slot 31 and the part 30 having a block which engages in this slot.

After the shovel has been thrust forward and'thus filled with material by the outward movement of the ram, it is moved back over the same path to the position shown by the full lines in Fig. 1, and then while the plunger of the motor and the ram are still moving rearwardly, the shovel is swung up and back over the machine to the dotted line' position. This is accomplished in this case by means of racks 34 which are supported on opposite sides of the platform or turntable 12, and by gear segments 35 at the rear ends of the portions 31 of the arms which support the shovel, the segments being arranged concentrically with respect to the pivot studs or trunnions 32 of the arms. These racks are arranged in the planes of the shovel arms and of the gear segments segments encounter the and are so located with respect to the latter that when the shovel is retracted to substantially the full line position of Fig. 1 the racks so that throughout the remaining rearward movement of the ram the segments roll on these racks, swinging the arms and the shovel about the pivot studs 32, and when the shovel reaches the dotted line position of Fig. l, the material is thrown into the car 15 or other element provided to receive the material. Then as the movement of the plunger of the motor is reversed, the gear segments roll forwardly over the racks carrying the shovel and the supporting arms forwardly and downwardly until the arms encounter the stops or bumpers 36 carried by brackets 37, which are secured to casti-ngs'38 carried by the two members 22 constituting the outer ram section. The arms rest on these stops or bumpers 36 while the shovel is being moved forwardly and rearwardly during the filling and retracting portions of the strokes of the ram and they resist the downward component of the ram thrust. The stops 36 can beadjusted in height by adjusting the positions of the brackets 37 so as to vary the normal position of the shovel and the inclination of the shovel arms during the forward andvrearward movements thereof, and the position of the shovel at the outer end of the arms can be adjusted so that the bottom or dilgging portion of the shovelwill always ma e the desired angle with respect to the material to be scooped up. T 0 permit this last mentioned adjustment, the shovel has a swivel connection shown at 28 with the forward arm members 30, and can be locked in any desired position by bolts 28 engaging in are shaped slots 28 at the outer ends of the arm members 30.

As the shovel is being swung over the machine it is desirable that it have as small a radius of movement as possible, and to that end the shovel arms are made telescopic. Additionally we provide means whereby the arms are automatically shortened as they swing over the machine and this is accomplished by providing at the inner or rear ends of the forward arm members 30, rollers 39 which engage cam surfaces 40 on the castings 38, which as before stated, move with the outer ram members and carryathe brackets 37 upon which the arms norm-ally rest and also the pivot studs 32 about which the arms turn. These cam surfaces are so shaped that as the shovel is swinging upwardly or downwardly past the forward end of the ram the effective length of the arms between the pivot studs 32 and the forward connecting points 2S will be such that the shovel will clear the ram, and to this end the forward portions of the cam surfaces consist substantially of arcs of a circle of pregiving the said elementa forward and rearward movement and aswinging movement over the machine to dumping position comprising forwardly and rearwardly'movable actuating members, one of which is movable forwardly and rearwardly relative to the other, and a pivoted armconnected to said material moving element and to said relatively movable actuatingmember.
