SCRAPER.

applicati@ med June 2,

T o all whom t may concern.' y

Be it known that I, JOSEPH S'. REYNOLDS,

a citizen of the; United States. residing at Los Angeles, in the county of Los Angeles, State of California, have invented anew' and useful Scraper, of which the following is a specification.

' which the inventor is familiar is socon;

This invention relatesl to Scrapers and relates particularly to a scoop control mechfanism therefor. 1

A type of scraper to which my invention.l

is especially applicable consistsjementially cfa scoop member havin-g la means pivoted thereto by which it may' be drawn. The

sc'o0p`is drawn over the ground to be levelled by a suitable tractive means sol that it scrapes the surface thereof and the removed earth accumulatesinthe scoop.l When the scoop is full, the cutting edge` theref is removed from engagement with the ground by the actuation of a. scoop'control mechanism. When it 'is desired to dump .thepload of dirt,1the control mechanism is further actuated in a manner such as 1will allow thesco'op tobe rotated into dumping posi- The general type ofscoop mechanism with structed and arranged as to-be engageably associated with the scoop at two places;

namely', near .each end thereof. It is in-fV .tended `that whenthe mechanism is actuated,

forl dumping, the engagements thereof with the scoop will be simultaneously released. -lt is found, however, that in 'actual practice they do not always 4release at the same time; Releasing of one engager prior .to the re- -leasing ofthe other allowsone -endof the scoop- .`to"`partially rotate. This vincurs a considerable strain in. the scoop and its associated parts, distortin the 4different parts .vide a control means which will overcome and maklngthe life o the-scraper much shorter than it 'would -be if this did not occur.

It is an object of this invention to, prothe above expressedV disadvantage. I do this by providing only Vone','engagement bevtween the control mechanismand the scoop. My inventionconsists essentially of stop members which are secured to or associated with the scoop and which rest in substantially the same circumferential plane. The

stop members are arrangedto be--enga d I position of the eng .line 5- -5 (if-Fig. 1.

Fig.- 6 is a perspective view vshowing the particulantype of fstop members whlch Iv 1924. Serial No. 717,273.

sired to dump a` manner' as to release the engagement between oneof. thestop members and the engager. This allows the scoop to rotate and the earth tn .loe dumped therefrom.

VIt isalso an object of this invention to i' provide a means for adjusting'the various positions which the scoop isI arranged to assume..4 1 provide the above mentioned fadi justability by adj ustably members with the scoop.

It isa further object of my invention to provide a means for regulatin the depth Iac complish this by mounting the releasing member on 'a swingable lever, which lever ."w

ofjcut, which the scoop will ta e.

mayl be swung from the drivers seat of the tractive vehicle pulling the scraper.. -A

swinging of the release arm will vary-thel the position ofthe stop. It is also an object of theinvention to provide a control ,mechanism which ma associating the stop"A ger and" thereby adjust A l sov very facilely be actuated from the drivers seatfof the traction vehicle.

` Further objects of the invention and the l I l specific advantages thereof will be made 8.5

evident hereinafter.

' Referring to the drawings Whichiare for` illustrative purposes only,

Flgxl l1s a side view of a scraper 4'embodying a control mechanism which 'resents the various features of my invention,

thescoop thereof being `shown 4in cutting .v

position in this view.

, Ffig. 2 is a plan view of Fig. 1.

Fig. 3 is a sect-ion taken on a plane as indicated by the line 3 8 of Fig. 2, this my control mechanism.

Fig. 4 `is a'fragmentary side view show# ing the relative position of the different parts when the scoop is in dumping and levelling position."

Fig. 5 is' a View taken -as indicated bythe em loy.'

ig. 7 -fis 'si-view showing `a reversible type of stop member. 1

As4 shown in the drawings, numeral 11 View clearly depicting the construction of 'i represents a scoop having a bottom 12 which is directed upwardly at the rear to form a back 13. Side members 14 are'secured to the bottom 12 and the back 13 in any'suitable manner, such asby angle irons. An angle iron 15 is riveted to the upper edge of the back 13 in order to prevent any distortion in the scraper. Runner bars 17 which may be in the form of angle irons, as shown, are l secured to the side 14 `by suitable rivets 18, the runner bar 17 having 4the shape substantially as shown in Fig. 1.' Runner shoes 19 are lsecured to'each of the runner bars 17 in any suitable manner, such as by rivets.v 20. vStub shaft blocks 22A are secured, as

shown, to the sides 14 by rivets 23, the blocks 22 presenting stub shafts 24 on which side `bars are rotatably disposed. The side bars 25 extend forwardly from the stub shaft 24 and are converged at the extreme forward end thereof, as clearly shown in Fig. 2, in a.`manner to meet the central bar 26. y

The side bars 25 and the central bar 26 are secured together in any suitable lmanner and have a link 27 secured thereto, which, as shown in Fig. 1, may extend into a clevice 28 provided on a tractor vehicle 29. A pin 30 s extendedthrough the legs of the clevice to retain the link 27 therein.

The central bar 26 atl its rearward endabuts against a cross bar 32. This cross bar 32 is bent rearwardly at each end thereof and is secured 'to the side bars by suitable rivets 33. Angle plates 34-are provided for the purpose of -rigidly securing the central bar 26 to the cross bar 32, there being rivets linto a shape similar to the runner bars 17.

Stops 47 are secured to the bar 44,1as clearly shown in Fig. 6. The stops "47 are preferably formed from a plate member which is .bent into a 'U-shape so as to form a pair of parallelv extending legs 48 which, when the stops are in place, extend to either side of the bary 44. Bolts 49 are provided for securing the stops 47 rigidly in place. The bar 44 is provided with a number of holes 51 adjacent' to each stop 47 so as to provide an A-adji'i/stabilityl of the stops l47,/these stops beingmoved in either direction as desired.

ivo't brackets 5,3 are secured, as clearly Vshown in Fig. 2to each side of the angle plates34 and extend downwardly as shown.

.forward end 61 of the lever 55.

A pivot pin 54 extends between the brackets 53 and an adjusting member or lever 55 is pivoted thereon. As shown in Fig. 2, the lever 55ha`s a member 56 secured thereto by rivets'l 57 at the rearward end thereof in a manner to provide a pair of parallel legs 59,-

these legs extending vto each side of the brackets 53. vThe adjusting member 55 is curved upwardly at and extends forwardly'so that the extreme forward end 61 thereof is in a position adjacent to the driversseat 62 ofthe tractor 29, the lever being offset as shown in Fig. 2 so asA to extend to one side thereof,l o

A toothed bar 64 is secured to the central bar 26, having teeth 65 formed on `the forward edge thereof. The lever 55 has an engaging pawl 67 arranged thereon, which is adapted to engage between the teeth 65 of the bar 64. Extending from the pawl 67 is a wire or connecting member 68, whichv at its forward endA attaches to a hand lever 470, this hand lever being secured at the extreme By de pressing the lever 7 O movement is imparted to thejwire 68 'in a manner to remove the 65 so that the lever 55 may be swung into any desired position, a springrbeing provided to return the pawl into engagement with the teeth 65 when the hand lever 70 is released. v

To the rearward side of the pivot 54 and at the extreme rearward end of the legs 59, a ,releasing member 0r arm 73 is pivoted, as shown, by a suitable pin or rivet 74. The arm 73 is preferably formed from a fiat steel bar which is bent into U-shape so as to provide a -pair of parallel extending legs or arms 76, as clearly shown in Fig. 5. An engager or roller 78 is secured by means of a pin 79 between the legs 76 ofthe releas- `pawl 67 from engagement between the teeth ico ing member 73. As shown inFig; 3..the engager 78 is arranged to enage an adjacent stop 47. Al means for holding the engager normally in engaging position, or, in other .-words, the arm 73 in its rearward position, is shown in the form of a rod 80 which has its forward end bent at 81 so as to extend through the central bar 26 for securing it Aat one end. Theother end of the rod 80 extends through a plate 83 which is' secured to the member 73. A collar 84 is placed on the rod 80 and a spring 84a is compressed between the collar 84 and-the plate 83 in a manner to yieldingly force the lever 73 into its rearward position. A nut 85 is screwed Aonto therearward end of the rod 80 to adjust the rearward position of the arm 7 3. A ring 86 is secured to the upper end of the arm 73 and has secured thereto an actuating member in the form of a rope 87 which extends forwardly and may be tied, as shown in Fig.' 1 at a suitable place 89 to the tractor 29.

j actuation of the mechanismjust dej scribed durin the.l usual operation of the scraper is asu ollows: j l

In Fig. lthefsccop is shown in scraping position, that is, the lforward' cuttingWed-ge 92 of the bottom. 12 ofthe scoop'is posi-j tioned'so as to be in engagement -withthe ound. The .scraper being. pulled (forward- J yover-the ground b the tractor v2,9 removes t e upper surface of7 the ground, illingthe lscoop 11. vVVhe'nthe scoop A11- is illed, it is lmoved from the position s h'own by the full lines inv Fig. 1 and Fig. -3 intocarrying'po-v l Sinon as shown 'by the 10aa-1 unes 94 of Fig. '3. This is'accomplished by the operator swinging ythe lever 55 from the posi? tion shown 'in ulllin'es in Fig. 3 into the dotted lines 96,',it being of'cour'se necessary to release the pawl 67 as described before. It will be seen that .the swing of the lever 55 swings the ,arm 73 upwardly, which moves the engager 78 upwardly, and the engager being' contacted by .a stop 47 will inturn` raise the stop' therewith.: rlhisaction re-ff sults in atilting ofthe scoop 11 in such af manner that the cutting'edge 92 isremoved from engagement with ,the ground, the scoop Athen riding on the rearward portion 98. When it is, desired toA dump the dirt, the

mechanism is actuated' so as to allow. the scoop to rotate in the direction indicated by the arrow100 of Fig. 3. This is accomplished by the o rator pulling forwardly on the ro'pe 87 .w ich swings the arm 73 for- .wardly,thereby removingthe engager 78 from engagement with the adjacent stop 47 v in a manner to allow the scoop torotate. If

the operator desires to dump the earth in a pile, such as for the purpose of forming irrigation ditches orthe like, :he holds 'theengager out of engagin position'until .the

second stop 47, indicate at 101, has passed the engager 78. If -`the operator desiresto spread t e earth over the surface of the ground,- he may do this by'merely holding the arm- 73 forward until the lengaged stop 47v passes the. engager 78. He then releases the arm 73. 'sc that the en ger will engage the second stop `101, whic lwill. retain the scoop in the position shown in Fig. 4. From Fig. 4 it willbe seen that the earth being dumped will be spread: over the surface of the ground by the edge 92 of the scoop. In order to prevent any excess movement in thescoop '11 when in scraping position, `or

carrying position, due4 to engagement of the" scoop with obstructions su'chas rocks, I provide an auxiliary sto 103 which is located tains the scoop in scraping orcarrying'posL tion. It will be seen that the engager, when resting between the stops 47 and 103, will prevent any up and down motion 'in 'fthel scoop. In order t'o assure the engager .en

` gaging the stop 47, I have made the. auxili-f of doubled.

ary .stop 103v slightly shorter, as clearly shown 1n 'F-ig. 4, this auxiliary stop 103 merely. bein long enough/to `engage-with the engager 78 when it isin its extreme rearwardv position. l`

' To ad'ust the amount ordept-h of cut that the; scraper will take, the operatorv merely lowers or raises the engagervby moving the adjusting lever up or down to suit. It:l

lever 55 a short distance in either directionwill be lscenfthat it is possible lto move the by engaging between other teeth on the bar 64.

lFurther adjustments mayi behad by 'changing the position ofthe stop 47 on the mounting `bar 44 by placing the bolts 49 through different holes 51 in the bar. Lilliewise -the levelling position of the scraper mayalso be adjusted vby moving the other stop 47 in a similar manner.

From Fig. 4 it will be seen that the lower stop 47 willengage the groundand may be subjected to attrition. In the event that this'd wear should ,be considerable, the stop 47- would wear'down tothe extent that it would fail to vperform its duty, and replacement would be necessary. In Fig. 7 is shown a 'be'used and wi'llaccomplish the same wor as any-of those Scrapers employing intri- 'cate mechanism. vMy invention provides a control which is very simple in construction, containing few parts, and which is very simple to operate. f
