`Unloading Apparatus, of'which the following is a full, clear, and exact description, reference being hady to the accompanying drawings.
This invention relates to loading and unloading apparatus, and has for its general object to provide an apparatus of this character having a wide range of operation and one which will render more positive and direct the control of the load carrying device. A further object of the invention is to enable the apparatus to be operated in an extremely efficient and convenient manner. Further and more limited objects of the invention will appear hereinafter.
In the drawings forming part hereof, Fig. 1 represents a side elevation of my apparatus showing the parts in the positions assumed when the load carrying device is taking its load; Fig. 2 a similar view showing the positions of the parts when the said device is in its unloading` position; and Fig. 3 a detail in section of the connections for operating the rigid members to which the load carrying device is connected.
Describing by reference characters the various parts illustrated herein, 1 denotes thc decl-z or platform of a carriage of the steamshovel type. This carriage is shown as provided with wheels 2 and a turn table 3 mounted on a truck 41. 5 denotes a boom on the deck or platform, which is rotatably mounted on the turn table by means of the wheels 6, in theusual manner. 'T denotes an engine which, through standard suitable connections (not-illustrated) is adapted to rotate the pinion 8 meshing with the gear 9 on the platform 3, therebyto rotate the deck or platform 1; 10 denotes a'druni ou the platform 1 driven by the engine 7 in any suitable manner, and 11i and 12 denote the geared heads of two other drums mounted on said platform. 13 denotes a lifting line for the boom 5, said line being wound upon the drum 10 and extending over a sheave 14, thence around a sheave 15 near the outer end of the boom. The end of this line is shown as fastened to a bail 16, which mayV Specification of Letters Patent.

Asuitable strut 17 having a guy 18 secured at one end thereto, the opposite end being led and secured to the carriage.
19 represents a crowding engine on the boom 5, said engine being adapted, bv suitable standard driving connections (not shown) to operate a pinion 20. The boom 5 is preferably of forked construction and is adapted to receive between the side members `thereof a longitudinally adjustable rigid `is ypivotally suspended by a chain sling 24 fromlthe end of the clipper stick, as by means of a bail or clevis 25. To the front Y or load receiving portion of the drag-line bu'cket is attached a chain bridle 26. The br1dle26 is connected at its forward end to a pulling or loading'line 27 which extends substantially parallel `with the dipper stick 21 around a sheave 28 carried by a bracket 28a above the side members of the boom 5 and thence'to oneofthe winding drums on the carriage platform, the drum shown herein being provided with the geared head 12. Connected to the outer end of the clipper stick is alifting line 29 which passes over a. sheave 30 on the end of the boom 5 and thence to another winding drum on the can riage, the drum shown being the one provided withthe geared'head 11. In Fig. 3 there is shown the pivotal driving connection between the member 21 and the boom 5. This connection includes the racks-22 and the'pinions 20. lA saddle block 22'EL having va central-projection 22" extending between the sides of the' member 21 and pivoted on the pinion shaft 2On vserves to maintain a driving connection between theracks and the pinions notwithstanding the swinging of the member 21 about such shaft.
In operation, the boom 5 may be set at any desired vertical angle by operating the drum 1.0. The dipper stick may be moved inwardly and outwardly, as desired, by operating the drum 20 through the crowding engine 19 and may be quickly and conveniently placed in operative relation to the work by reason of such adjustment and by means of the line 29. In the drawing, the bucket is it has the advantagesover leading the liner Y Vdirectly to the drum on'the carriage platform Vaction'may, if desirable, be furtherV facilitated by elevating the boom 5. Furthermore, in practice, I will make the rigid member much longer than that employed for the or- Y dinary dippcr stick, whereby the range of aetion may be correspondingly increased.
The bucket 23 having been placed in operative relation to the work by means of the member 2-1, the loading line 27 is wound upon a suitable drum and the crowding engine is operated at the same time to move the member -21 so that the bucket 23 is free to be dragged along the ground and to take its' load inthe usual manner. When the member 21 and the line 27 have been taken in to the desired extent, the crowding engine may be lstopped and thepull upon the line 27 will then tilt the. bucket to its load-carrying position, this tilting being accomplished through the dumping line 31. This line is fastened at one end 'toy the line 27, 'or the bridle 26, and extends about a sheave 32 ont-heend of the member 21'and is `connected at its fixed end to 'the front of the bucket. With lthis arrangement it'will be evident that, by` tauteni'ng the lin'e 27 ,with reference to the memp ber 21, the bucket 23 will'be caused to Vassume Van'upright or load-retaining position. The` member 21` may then beswung'i-na vertical plane about its pivot by means of the line 29. The boom 5 may then be rotated Vin the usual manner until the. memberv 21 andbueket23 -areat the desired unloading station, whereupon the bucketmay be dumped by slacking' off the line 27, allowing the bucket to pivot upon the slings 24E to dumping position.
. It will be noted that the loading line 27 cxtends substantially parallel to the member 21. This'enables me to handle the bucketin an extremely efficient manner.v Furthermore,
in that the line operates more nearly parallel to the lifting Vline 29 and that it does'not Vform an appreciable angle with the member :21 whereby there willxbeany tendency to buckle orbreak the said member. through set- "fting up onthe line." A' further and importantadvantage of my invent-ionresides in the fact that, by the construction shown, the
vbucket may be quickly and positively 'placedv v Vinrboth. its loading and unloading position,

raise and lower the boom 5, and the adjusting of the .dipper stick will be Vsufiicient to accommodateall ordinary ranges of operation; However, should it be desirable to increase somewhat the outer limit of such operation, vthe boomV 5 may be lowered, Vthus bringing the pivotal point forthe member 21 further away from the carriage. Also-,j by elevating the boom 5 to a nearly vertical position, this pivotal point may bev brought nearer to the carriage, and the dipper stick or 'member 21 may operate close to the platform without requiring its lower end to be swung Yinwardly beyond a vertical line. ecause ofY the length of the member 21 and the convenience of operating the same, vertical adjustment of the boom 5 will Yordinarily beV un- The member21 may be run inwardly by operating t-he pinions 20 in the appropriate direction from the crowding engine 19. The 'operation in the reverse directionV may be accomplished either by reversing the crowd- `ing engine orby the employment of a clutch whereby the driving connection between the pinion 20 and the engine may be broken, thereby to enable the said member andthe bucket or other load-carrying device supported therefrom to be run .outwardly by gravity, merely slacking olf the lines 27 and 29.

Forthe purpose of guiding the lines'27 and 29, sheaves are preferably employed; but I do not contemplate limitingthe guiding means 'to the particular elements Vshown herein or otherwise to limit Vthe scope of the invention except as such limitationfniay be rendered necessary by the'state of the prior art.:
Having thus describcdmy invention what YI claim is direction of its length, a drag line bucket, a
sling suspending said buek'etrfrom the Vouter endof said member, a loadingline connected to said bucket .and extendingover a'sheave located adjacent toV thepivotal Vconnection between said member` andsaid boom, a
dumpingline connected at one end Vto the loading line and atlits opposite end tothe bucket and extending around `a sheave on said member, a lifting line connectedwith said memberand guided byY said boom, and means for taking in and slacking off the loading and lifting lines,
