PAU 'L, MINNESOTA,- ASSIGNOR '10' HERNTSCHFEGER CORPO- RATIQN, F MILWAUKEE; WISCUNSIEN' A CORPORATION 031" WISCONSIN EXGAVA-TING Macaw-Elm Original applicationfiled: September 18-, 1929', Serial No. 393,562. Dividedand this application filed January 12, 1931.
This invention relates to amethod ofloading heavyjex'cavating machines on railway cars for shipment and for unloading such excavating machinery from railway cars at a 5 the point of use.
The present application is a division of my pending application for excavat1ng'"machinery, filed September 18, 1929; Serial No. f
In excavating machinery ofthi'skin'd' dequired, the machine, as a whole as well as its signed to handle a three cubic yard shovel dipper or a three and a half cubic yard dragline bucket or larger or smaller buckets depending upon the length of the boom recomponent parts, is of such unusually large size as to present a serious and diiticult problem-inconnection with the shipping of the machine from the place ofits manufacture'to the: place of its use or in the shipping ofthe machine from one place of use to another.
7 In fact, heretofore, it has been necessary to ship such a machine disassembled and then set it up or assemble it at the place of use.
" "20 t i as to appreciate that these practically complete assembly and disassembly operations which are incident to each shipping'jresult in considerable expense as well as the L; vexpenditure ofa great deal of labor'andithe loss of. time.
The type of excavating machineryto which the present method is applicable'usu'ally' include a main frame, traction devices and a drive for the traction ClGVlCQS and has these instrumentalit-ies so organized that the traction devices at both sidesof' the machine may be easily removed as units to permit the main frame and all of the parts carried thereby except the boom to be shipped on alfl'at car. Booms: in this type of machine are already easily removed and with the presentinvention the boom; and the traction devices are shipped on a separate flat-car. All that is required for removing or replacing the traction devices is-the r'emovalof a few'bolts'and nuts, the traction devices and main frame and elements of the drive of the traction devices being engageable and disengageable from each other by a. relatively lateral shifting' movement. Laborious' and d'ifiicultf astion is, in its broader aspects, directed to the application and removal of separate traction devices to the main frame of an excavating machine and consists insupporting the main rams independently of the traction devices,
supporting the tra cti'ondevices at either side of the' machine, shifting the traction devices laterally toengage them with or disengage them from the main frame and applying or removing the fastening devices utilized for seci'iring the traction devices to the main frame. In: carrying out the loading of the machine onto'a car for shipment the method involves-running the excavating machine up lntop'osition wherein its traction-devices are supported partly on the car and" partly on temporary supports provided along the car, supporting the main frame independently of the traction devices, disconnecting the tractipn devic'es' from the main frame and shift ing th m over? onto the temporary supports and then loweringthe main frame onto the Call.
In carrying out the unloading operation the method involves providing temporary supportsalong the sid'e' ofthe car, elevating! themain frame, placing the traction devices onthe temporary supports, then securing them" to the elevated" main frame and then runnin'g'the machine ofi? of the car on its traction devices;
Referring now to the drawings:
Figure l" is a diagrammatic view in'e'levation showing how acomplete excavating machine is first brought into position withthe frame of the machine and the parts carried-thereb properly overlying a flat car;
Figure 2 is aview similar to Figure 1' but showing the traction devices removed andthe main frame lowered. into position on the flat car;
Figure 3 is a view very similar to'Fignre Qb'ut showing the traction devices entirely removed;-
Figure 4 shows the traction devices mounted on a Hat car;
Figure 5 isa view partly in top plan and partly in horizontal section illustrating the main frame and the tractiondevices and the drive therefor and showing how these parts i are assembled and disassembled; and
' of the mainframe from which the traction Figure 6 is a view in elevation of that side devices have been removed. Referrmg to the drawings, the numeral 1 designates generally the main frame of. a? machine whichis supported, as willbe here'-.
inafter more fully described, on traction devices 2 of the type having endless flexible treads or self-laying tracks. A revolving platform '3 is supported on themain frame 1 for rotation in the usual manner and this revolving platformcarries the boom, the power.
plant and the other instrumentalities of the machine which are well known and widely used and are therefore not shown. 7
Referring now especially to Figures 5 and otherwise suitably connected'to the body of the main frame. The outer face 5", of each lug 5 ismachined to a flat plane, surface and the under surface of the outer end portion of each lug-is similarly machined to present a jdownwardly facing shoulder 6. .In the as sembly; the lugs-5 engage and are supported H I onbrackets designated generally at-7, and
[to "the frames 8 of the traction devices 2. 7 Each bracket 7 has amachined face 7 adaptintegral with or otherwise fixedly connected 5- of its lug 5 ,and'the lower "portion of each bracket 7 is formed with a machined seat or shoulder 9 upon which th-e correspondingly er assembled relation, bolt holes 10, 11 and 12 on each lug are alined with correspondlngly positioned bolt holes 13, 14' and 15 formed in the associated brackets 7 and ad jacent portion of the traction frame .8. The bolt holes 11 and 14 are recessed or countersunk as indicated at 11 and14 respectively,
to define a pocket for the reception of a key or washer 16 so that the bolts and nuts 18 extendlng through the bolt holes 10, 11, 12,
13, 14 and 15 need only take the strain of.
holding theparts assembled and are relieved of all shearing stresses; ,In other words, the
. coacting shouldersvof the lugs and brackets take thevertical' load and the keys 16 vtake the stresses set up by the tendency of the wheels 23 which mesh with the pins 24 of the links 25 ofthe endless flexible treads, The
formed shoulder 6 of the associated lug, 5 rests, When the lugs 5 at either si'de of the 1 mainframe and the brackets7 of the associ- I .ated traction devices are brought into propends of the shaft 22 project beyond the sprocket wheels 23 and are receivedin the openings of I-bolts 26. Nuts 27 and 28 are threaded on the I-bolt 26v and engage the opposite sides of apertured bearing wings or 'abutments 29 cast'integral with the traction frame 8 or otherwise suitably fixedthereto' and through the openings of which the end of each'traction frameS, hasa bearing shanksof the I-bolts extend; :The opposite 7 for the reception of a drive shaft 30 on which a N drivingsprockets 31 are keyed, the driv ng sprockets 31 coacting with the pins 24 of the links 25 to positively drive the 'flexibletreads. Q 3
On eachshaft30 adjacent the inner driving sprocket 31, a driven gear wheel 32 is fixed and is enclosed in a gear casing 33. Each shaft 30 extends inwardly beyond its driven gear wheel 32 and gear casing 33 and has its inner portion 34adapted tobe journaled in a bearing 35 provided in the main frame. A" removable lock collar '36is provided for the inner end of each shaft'34 and when theshaft 34 is received'in its bearing 35 in the main frame the collar 36 is releasably'secured in position by a set screw or look screw 37 and" coacts with the adj acentjsurfaceof the main frame to'hold the shaft'34 againstioutward v displacement; Each gear casing33 has an opening 38 in its inner face'to permit of the passage into and outof the casing of adrive 7 t-ioned just alongside of the adjacent outer signed to intermesh withthe driven gear 32, when the machine is assembled. These drive" pinions 39 are preferably fixed on the outer ends of sleeves 42 and the sleeves 42 are rotatably mounted on a transverse drives'haft 43 driven from the power plant of the machine by means of the usual gearing 41. Clutches 40 serve to clutch the sleeve'shafts 42 to the drive shaft 43' when desired. The ends of the drive shaft 43 project beyond the drive pinions 39 and are adapted to be received in flanged bearing openings 45 in the gear casing'33. 7
A machine so constructed and organized may be conveniently disassembled and assembled for shipment in accordance with the pinion 39. ';Each ,drivingpin'ion' 39 is posifollowing novel method. The machine is completely assembled'at the place of its manufacture and may be run under its own power Figure l. The main frame is then jacked up, jacks J being'positioned below portions 50 of the'main frame. The traction devices are then removed, by taking out the bolts 18, removing the set collars 36 and shifting the traction devices laterally away from the I main frame. Such lateral shifting of. the traction devices disengages-the gears 32 from their a driving pinions and theshafts 34 out of their bearings as well as disengages the coacting lugs 5 and brackets 7. The jacks J are then manipulated to lower the main frame down onto the fiat car, as illustrated in Figures 2 and 3. The traction devices may be shipped separately on a flat'car as shown in Figure 4 and usually the boom is also mounted on the flat car with the traction devices. Assembly of the traction devices with the main frame may be carried out on the flat car by jacking up the main frame, placing the traction devices on suitable supporting structure S built up alongside of the flat car, shifting the traction devices laterally to bring the shafts 34: into the bearings 35, the gears 32 and 39 into mesh, and the brackets 7 into engagement with the lugs 5, and then assembling and securing the bolts and nuts 18 and the set collars 36. The
traction devices are complete self-contained units carrying the adjustment for the idle sprockets and the driven gearing for the driving sprockets and are assembled and disassembled as units.
The invention claimed is:
1. The hereindescribed method of loadin on to a'car for shipment an excavating machine of the type having a main frame and traction devices removahly secured thereto which consists in providing temporary supports along the sides of the car, running the excavating machine up into position wherein its traction devices are supported partly on the car and partly on said temporary supports, supporting the main frame independently of the traction devices, disconnecting the traction devices from the main frame and shifting them over on to the temporary supports, and then lowering the main frame on to the car.
2. The hereindescribed method of unloading an excavating machine of the type having a main frame and separate traction devices adapted to be removably secured to the main frame and in which the main frame is supported directly upon the car during shipment and which consists of providing temporary supports along the side of the car, elevating the main frame, placing the traction devices on the temporary supports, then securing them to the elevated main frame and then running the machine 05 of the car on its traction devices.
In witness whereof, I hereto aflix my signature.
