.7 claims( (o1. 214-110) This invention relates to loading machines and l more particularly to machines for loading coal A into mine cars within the mine.

Anf object of the present invention is to provide a loading machine which will facilitate to a great degree the loading of coal into mine cars and lwhich embodies an improved shovel construction, means for feeding the shovel, elevat ing the shovel, and retracting the shovel, together with means for guiding the Yshovel toV a position to discharge the load thereof into the car being loaded as well as improved means for discharging the contents of the shovel therefrom; and the invention together with its objects and advanf tages will be best understood from a studyof lll' the following description taken in connection Withthe accompanying drawings wherein1` Y Figure 1 is a top plan Vview showing the loading machine and with theshovel retracted and in a lowered position, Y Y Y Y Figure 2 isa side elevational View of the machine,

Y Figure 12 is a wiring diagram, and

Figure 13 is a plan View illustrating the manner of using the device when loading coal at a corner of the tunnel. l

Referring to A the drawings by reference numerals it will be seen that in accordance with the present invention there is provided a carriage 5 suitably equipped with wheels 6 to ride on the usual mine track rails 1. Mounted on the carriage 5 is a super-structure 8 which supports a pair of opposed parallel angle iron rails II. Y

Hinged to the forward end of the rails Il are plates I2 equipped, as shown in Figure 11, Vwith 55,. clamps I3 for securing thereto at the desired position, of adjustment substantially I-beamelevator rails I4. I s

Movablealong the elevator rails I4 are elevator blocks I5 equipped with rollers IB; as shown in Figure 9, and -which rollers operate in slots I1 Y providedV therefor in the railsy I4 whereby to guide theI blocks I5 in their movement lengthwise of the railsAY E4 and also to retain the blocks I5 in. sliding Vengagement with the rails I4.

` Carried bythe elevatorV slide blocks I5 is an elevator platform Irthat adjacent one end thereof is swivelly connected with the blocks I5 as at I9,- (See Figuref4.)-

Manifestly the blocks I''will move downwardly along the rails I4 by gravity and under their own weight'.Y For moving the blocks I5 upwardly onthe rails I4Hthere is provided a cable 20 an intermediate portion of'which is suitably windableonfadrum 2|, mounted onthe truck 5 and opposite'end'portions of which are suitably journaled over suitably positioned sheaths or pulleys 22 provided at the upper ends of the elevator rails` I4 and at? their terminals are secured to the blocks I5'as at-23.` The ends of the cables are also jourvnaled over suitable pulleys 274 suitably provided therefor as suggested in Figure 5. It will thus be seen that when the cable 20 is caused to wind on the drum 2l blocks I5 will move upwardly on the rails I4 carrying with them the elevator I8 and the shovel hereinafter more fully mentioned, restingjon the elevator platform4 I8'- Also, and as best shown in Figure 1, the elevator platform I8-`is retained in a'substantially horizontal position at' all times through the medium of exible elements 25 secured atV one end to the blocks I5 andat a relatively opposite end to the sides of the platformY I8 intermediate the front and rear ends oftheplatform.

Thej shovel is indicated by the reference numeral 26V and atits rear end is provided Vwith crossed 'bars 21 to which is secured as at 28 one end of afcable 29;

Y Cable 2.9 istramedfover rollers' 30, 3l provided on the ,supergstructure 870i the truck 5, and is alsotrained over pulleys 32, 33, hereinafter more fullyjreferred to, as well as over a pulley 34 suitably mounted at oneside of the ktruck 5; the cable 2,9 being windable on a drum 35. f

1 For supportingrthe cables 32, 33 there is provided, asbest shown in Figure 6, a cross-bar 36 that is supported between a' pair of mine jacks 31 suitably Vpositioned within the minerearwardly `of the innermost ends of the mine track rails 1 and(r these pulleys 32, 33 are i suitably mounted, one "at about the center, and one adjaf form I8 has been raised to the mine car III to be filled.

'Ihe shovel 26 is also equipped with a follower or ejector 49 that is constrained to move longitudinally of the shovel through the medium o'f'a. xed guide rib 4I on the bottomof the shovel and a complementarily formed notch 42 provided in the lower edge of the follower 40 as will be clear from a study of Figure 8.

Secured to the rear side of the follower 4U is onewend of a cable 43 that Jentends `laterally therefrom and is trained over suitable pulleys 44, 45. The cable 43 is windable'on a drum 46. In this connection, it will be understood that cable 43 willl be free to payout from the drum 46 while the shovel 26 isbeing moved to a dischargingu position ontoV the platform 39. However, when the VAshovel 26mis in such a position on the platform 39a braking action will be applied to the rdrum 46 preventing further paying out of the cable 43. At the same time the shovel cable 29 will continue tol wind on its drum 35 so that the shovel 26 will move rearwardly relative to the follower 40 as a ,consequence of which the coal willbe forced frein the shovel through the opening in the platform 39 and into the mine car I9. 1

Further in accordance with the present invention there are provided, to be laid in advance ofthe forward ends of the mine track rails 1 a pair `of opposed parallel shovel feeding arms 41 that are adapted to slide through guides- 48, of any suitable construction. anchorednin position within" the mine through the medium of mine jacks 49. The guides 4B areconnected Ywith thejacks 4,9,atat 50. V For `feeding the shovel 2 6 forwardly there .is provided a pair of cables 50, 5I.` Thereis one cable 56, 5I for each arm. 41 and a description ofthe manner in which one cable 50, 5I is asscented with the shovel,A 26 ,and arm '41 win teach' the manner 'of associating the cable with the shovel and its arm 41. Thus, referring, for example, to cable 50, ity will be seen that the same at one end thereof is suitably secured to one side of the shovel 26 through the medium of an eye 52. Cable 59 is trained over a pulley 53 mounted adjacent the forward end of an arm 41 as shown in Figure 7, and as alsov shown in said figure 'cable 50 `is trained `rearwardly over a p pulley 54 'mounted adjacent the rear end of the arm 41 and thenextended forwardly where it is trained over an eccentrically mounted pulley 55 the rshaft 56 for which is suitably journaled vertically in a guide 4 From the pulley 56 the cable 50 rextends rearwardly through a guide 51 provided laterally of the arm 41 adjacent the rear end of said arm and then is trained over a pulley 58 mounted 'at one side of the truck 5, cable 50 being windable on a drum 59i In this connection it will be noted 'that cable 5I is trained'over a pulley 60 suitably mounted on the truck 5 at the side thereofy opposite 'to the pulley 58 and is windable on a um 6I..vv It will thus be seen that by simultaneously winding the cable The guides 48 are,

5| on drum 6I and cable 50 on drum 59 shovel 26 will be forced forwardly to a position between the forwardmost ends of the arms 41, the shovel 26 moving to this position relative to the arms 41.

At the forwardmost ends thereof, arms 41 are provided with electro-magnets 62 which attract and hold the shovel 26 at this position so that, as the cables 50, 5I continue to wind on their respective drums 59, 6I arms 41 together with the 1 shovel 26 move forwardly, arms 41 passing through the guides 48 and the shovel 26 being in this manner forced into the pile of coal.

In retracting the shovel 26 after coal has been loaded thereon the operation is substantially the reverse of that just described.

With the coal-loaded shovel 26 on the platform I8 cable 22 then winds on its drum 2I to raisethe platform I8 to a position aligning with the rails I I. When this has been accomplished cable 29 again goes into operation, that is to say is again further wound on its drum for drawing the coal-loaded shovel from off of the elevator platform I8 onto the rails II and from the rails II onto the loading platform 39.

As before set out when the coal-loaded shovel 26 is properly positioned on the platform 39 further paying out of the follower cable 43 is stopped by applying a braking action to the drum 46 while cable 29 will continue to wind on its drum 35 thus causing the shovel 26 to move rearwardly relative to the follower 49 with the result that the coal will be forced from the shovel through the opening in the platform 38 and into the mine car IIJ. n

The beforementioned drums 2I, 35, 46, 59 and 6I form part of a well-known type of a multipledrum electric hoist which embodies in addition to these drums an electric motor 62 that drives the shaft on which these drums, together with suitable clutches and brake mechanisms, are mounted.

Sincesuch a device is no part of my invention and is of a type clearly disclosed in a 1937 catalogue published by the Ingersoll-Rand Company, further detailed description thereof is deemed unnecessary.

Further in accordance with the present invention there is connected with the shaft 56 of becomes difficult to force the shovel into the coal pile motors 13 may be set in operation. The resultant hammer effect of the sheavewheels or pulleys 55 on the respective cables 5I), 5I vwill finally result in the shovel being forced into the 'coal pile.

'In Figure 12 there 'are shcwn the electromagnets '62 previously referred to, as well as the motor 13, and the power motor 12. The control switches for the magnets '62 are also shown in Figure l2 and indicated by the reference numeral 14 wrm@ the switch for the motors '1a is indicated by the reference numeral 15 and the switch 'for the motor 12 is indicated by the reference numeral 16. It will vthus be lseen that whenever it is desired, as ofcourse will be the case each time the shovel 26 moves Youtwardly to a position between vthe magnet 62, to complete the circuit through the magnets -62, switches 14 will be moved to a closed position. Upon retraction of the arms '41 and to release shovel 26 to "permit Ythellatter to further retract relative to the arms 41 switches 14 are moved to open position whereby the vmagnets 6 2 will become de-energized.

Wheneverit is desired to bring the motors 13 in operation switch 15 isclosed; while when it is rdesiredtobring tle motor 12 -in operation, switch V1B is closed. s

,In Figure 13 is illustrated the manner in which the device may be usedwhen it is necessary, for the purpose of loading coal into mine cars, to cause the shovel to move around or negotiate a corner in the mine tunnel.v Where such is necessary guides 48, arms 41, and associated parts are placed in the arm of the'tunnel in which the pile of coal is located; and at the corner of the tunnel, for the purpose of accom- Inodating the cables 50, 5l there are suitably mounted pulleys 11, 18, respectively. When retracting the shovel 26 the cable43 connected with the follower lill, and trained over a suitably arranged pulley 19, is made use of to draw the shovel from the coal pile, to approximately the rcorner of the tunnel after which the pull of cable #i3 is released and cable 29 is then made use of for turning the shovelintoI a position substantially aligning with the elevator platform i8 and also for drawing the shovel onto the elevator platform as'clearly suggested in Figure 13.. Obviously, after-the shovelhas once been p-lacedron the platform I8 the operation of'un loading the shovel is identical with that herein'- before fully described.v

It is thought that a clear understanding -of theconstruction, utility, operation and advantages of a loading machine of this character will be had without a more detailed description.
