ERICK VON MEI-IREN, OF DULU'IH, MINNESTA, ASSIGNOR T0 HOAR SI-IOVEL COM-' I'AN'Y, OF DULUTH MINNESOTA,
A CORPOBATION OF MINNESO'I'A.
MEGI-IANICAL SHO'VEL.
Application flled October 12, 1925. Serial N0. 62,005.
T0 a]? w/wm it ma concern:
Be ioknown that I, E1TICK VON MEHREN, a subject 015 vthe King of Denmark, residing at Duluth, in the conty 0f St. Louis und State of' Minnesota have invented cerbain new and useful Improv emeqts in Mechanical Shovels, of Whi0h the following is a specification, reference bei1'1g hacl therein t0 the accompanying dmwing.
This invention relates 130 mechanical shovels-and has special reference t0 specific means for the manipulation thereof, and th'e shoyel here illustrated and described is especially designe;d f01' tunnelling purposes where room for operating the device 1nay be considerably restricted such as experiencec]. in 002ml, iron, 01 other mines.
The principal object of the invention is,
to provide a, shovel ofthis type having the maxinnim of efficiency both in digging zmd mani ulating its 10a Oter objects and advantages will appear in the furtherdescription 0:E the invention;
' Referring DOW to the accompanying drawing forming part of this application and in which like reference eharacters indicate 1 like 'parts F igure l is a side elevation 0f one of the improved shovels with the dipper fully advanced in position for digging, anc1 Figure 2 is a slightly enlargediear elevation shovving the dipper in its fully retarded position, such position being indicated in dotted lines in Figure 1.
The shovel, as before stated, is of the tunnelling type, and comprises the tram ear l, carrying the turntable 2 01: any well known construction, upon which is pivotally mounted the superstructure 3, this latter being preferably considerably narrower in construction than the tram car, providing 1oom ab 0ne side thereof and above the car for convenient seating of the operator; such seat being illustrated ab 4.
The superstructure 3 carries the operating motor 01' motors, which may be either air, electric, 01' gas, as desired, and, in Figure l, one 0f the air motors is illustrated at 5 and the controlling va1ves of the twoothers are shown ab 6 and 7 they being controlled by the levers illustrated at 8. By these motors the superstructure may be rotated in either direction, and the shovel reciprocated, their connections and operation not being here illustrated as they are well known in the art WVithin the upper side Walls 9 of the superstructure 3 is a track in which is reoiprocably mounted the carriage 10, it having a sei: of eight rollers 01 wheels 11 f0r nonfrictional engagemnt with the side walls 9.
The crowding motor, controlled by the va l ve 6, operates the carfiage operating outboard 0f the end 0f the carriage as at- 19, the dipper stick 20, having upon its forward end the dipper 21. T0 the opposite end 0f the dipper stick as at .22 is attached the operating 1ine 23, which inay be either a 1ine or chain as desired. This leads ove r the roller 24 upon the free end 01: the auxiliary dipper stick down t0 and about, the sheave 25, pivotally mountecl as at 26within b1"ckets 27 upon the upper end of the eat'- riage 10, thence to .and about the sheave 28,-
Which is pivoted as ab 29 in the rear up: per end of the superstructure 3, thence to a drum, operated by either one 'of the other two motors in the superstructure, said drum not being shown. By this means the dipper and operating sticks am controlled independently 0f the operation of the carriage, and the dipper controlling line 23, passing about the end of the auxiliary dipper stick 18 and directly down to and about the sheave 25 m0unted upon the carriage, at all times pulls directly downwardly in respect to the free end 0f the auxiliary dipper stick; this being true irrespective of the longitudinal position 0f the carriage upon the superstructure 3; Whereas, in previously constructed shovels of this type, where the line 23 leads directly from the free end of the dip er stick 20 over the auxiliary di per st1c to and about the sheave 28, txe downward stress upon the free end of the auxiliary dipper st1ck was considerably greater, and the benefits de- 11V8d froin the auxiliary stick much lass a preciated in the digging manipulation of tle dipper.
The rearmost end of the dipper stick 18 has depending fiherefrom a leg 29 from either side thereoi, which, when the dipper stick is lowered in t'he position shown in dotted 1ines Fig. l, rast qpon the laterally extending webs 30 of the carriage 10, 2nd the upwud travel of tha free end 0f the auxiliary ippar stick is limited by the chain 31, one end 0f which is attached to the dipper stick und the other end t0 the carriage.
The shmel here illus'trated is shown with the tran1 car haflng wheelsof greater diameter ab 0ne end than a't the other, so as to gi*ve the superstructure an inclined osition at all ti1nes which is 110t only bemfiial in the position '0'f the shovel f01 digging purposes but also has 21 tendency to elevate same for loading into a tram car when the superstructure is rotated to a positionopposite to tha;t shown in Figure 1 of the drawing, this however, being 0'1d in .1jhe art.
It is obviou-s that if a forward thrust 01 the carriage is desirabl'e when the dipper is digging, the 1ine 23 may be roven upon the opposite 01 realmost side 0'f h@ sheav'e 25 and about a sheav'e not shown 0n the shaft upon wh-ich the sheave 15 is 1nounted, and thence to the Power n1e'chanism.
Hav-ing Chns described my invention, what I claim and desire t0 secure by Letters Pat ent, is:
l. In con1bination u tram car having a turntab1e thereupon, a ower containing superstmcwe pivotally carried u13011 the turntable, a carriage reciprocably carried within the superstructure, an auxiliary dipper stick plv0tally carried up0n the carriage, a (lippe1 and dipper stick proper pivotally carried upon t-he auxiliary dipper stick, a dipper manip'ulatin5; line attached to the free end 0f the dipper leading over the dipper stick, downwztrdly abou-t a sheave in the rear end 0f ehe eatriage and thence to the power mechanism within the superstructure.
2. In 'a mechanical shovel ehe combination With a vehicle a Superstructure supported toturn upon the vehic1e, a track car ried by the superstructure, a reciprocable carriage carried by the superstructure, an auxiliary dipper stick pivotally carried upon 0ne end 0f the carriage, a dipper stick und dipper carried upon the auxiliary stick, a sheave in the oppsite end 0f the carriage, and a single line for operating both f the sticks and in con'sjtant engagement Wi h the sheave in the carriage.
3. A mchanical shovel co mprisit1g a 1'0- tatable structur6, a travelling Carriage': mounted in said structure, an auxilia1f31 stick pivotally supported upon 0na end o'i ahe ca 1- riage, a stick oarrying a dipper pivotalljr supported on the 2Luxi'liary stick, and a flexible dipper operating means connected t0 the dipper carrying stick, bearing upoh the fiee en'd of the auxiliary stick, and passing t-hrough the opposite end 0f the carriage, substantial'ly ms und, for the purpose descri bed.
4. The combination with a mechanicul shovel comprising a vehicle hzwing a turntable thereupon, a s .1perstructure supportecl upon the turntable, an inclined track carried by the sup'erstructure a reciproca] c-arriage carried. by the superstruc'ture, an auxiliar'y dipper stick pivotally carried np0n the car riage, a dipper stik und dipper cgu1ied pon t-he ziuxiliary stick, and (L single line f0r simultaneously operating; both dipper sticks, 0f mean-s whereby the o'perating line is in constanc engagement with the IG2II" end 01 the carriage.
In testimony whereof I hereunto afiix my signature.
