i To all whom it may concern.'

Be it known that l, HERBERT L. Ginza, a

citizen o'f the United States, residing at Los Angeles, in the county of4 Los Angeles and State of California,have invented certain' new and useful Improvements in Scraper- Buckets,.of which thefollowing is a specification.

This invention relates to improvements in scraping buckets and particularly to that -class of buckets which is capable of automatic. control .in the scraping and dumping .dykes of the material to beoperated upon,

so as, to sc oop up'sucli'material andcarry to any point where 1t is desired to deposit it. It is the object of the invention to so cony y struct such a scraping bucket that it canbe made to scrape .or o dump at any pointV within the range of its movement.

, With these -and other objects in view, the invention consists in certain novel constructions, combinations and arrangements of parts, as will be hereinafter fully described and claimed.l

showing the bucketwhen it 1s being drawnback to its initial position bythe tail line so as to'be in readiness for the next scraping operation.

The scraper of this invention-is adapted for having a sliding action upon the' ground 4 'Orthematerial to `be moved and is thus capable of scooping upA or .scraping such material and conveying itto any desired point-.where it. can be dumped, relayed,

, packed or otherwise arranged as desired, at

W1ll.

In the drawings 1 indicates the scraper it to collect or scrape the material that is to beoperated upon.' To this end, the forward scraping edge of the bucket is bent in- 'wardly a little, as shown at 4.

5 indicates a bail which is pivoted at 6 near the front end of the bucket for pulling the bucket forward when scraping. A head line or cable 7 is connected with the bail and extends to any suitable source of ower, as for instance a power driven winding drum as at 8.

In order to effectthe dumping of the bucket and also to retract or draw back the bucket in readiness forthe next scraping operation, a tail 'line or cable 9 -is pivotally secured to the closed end 3 of the bucket, as at 10. This tail line is also extended,in practice to a power drum as l1. The cooperation of the head and tail lines 7 and 9, in producing the various actions of the bucket 1"is secured by the use of an intermediate connecting member or bar 12. The member 12 is pivotedat 13 to the bail 5 at one of its ends,.while the other end of said bar or member carries a pulley 14 through which the tail line 9 is passed. The member 12 is made of such a length that when the tail line is drawn tight, the swinging vend of the bail 5 will be lbrought quite close to the rear closed end ofthe bucket 1, as shown in Figs. 3 and 4. v

The action of the bucket in accomplish- .ing its purposes, is best secured when the4 headand tail lines are passed through pull leys that are quite widely separatedas illuse ltrated in Fig. 1 of the drawing, where the head line 7 is shown as passing around a Specification of Letters Fatent. Patented N075, 22, 1910,

pulley 15 and thence backwardly toward a point to the rear of the hoisting drum 8 -where it passes over another pulley 16 and thence downwardly to the said drum 8. The

p tail 'line 9, on the other hand, extends from the bucket in the opposite. direction and is passed around a pulley 17 and thence to the winding drum 11. vThe .pulleys 15 and 17 may be arranged at various distances from each other, from timeto time, as found most suitable for the work in hand, but their particular manner of mounting forms no part TWith the bucket l in its initial position, say

near the actuating drums of the head and tail lines, the drum is caused to pull upon the head lines 7, the drumll at the same ftber line so as to run thereon, whereby the time, being permitted to run free so as to allow of plenty- 'Ihe parts will immediately assume the por sition shown in full lines in Fig. l and also -is empty,

as shown in Fig: 2 and a continued pulling,` upon the head line 7 will cause the bucket to scrape up the material that is tobe moved, and after the bucket is full, it will continue to slide until the point for dumping is reached. The drum ll is next operated to exerta pull upon the tail line 9, which will draw the rear end of the bucket toward the pulley lll and thus lift it so as to permit the contents of the bucket to slide out at the fon ward end, as clearly illustrated in Fig. of the drawing. In this operation a sutli cient pull is maintained upon both the head and tail lines to slightly lift the whole bucket and to raise it sufficiently to enable'it to clear itselfof the load. Then the bucket the head line 7 is allowed to run slack and the drinn ll is caused to wind in the tail line 9 and thus return the bucket to a proper position for scraping` a new load, the parts assuming' the position shown in Fig. et of the drawing. The operations just described are repeated Vas often as desired and as shown in dotted lines in Fig. l, the 'scraped material can be deposited at any point along the line of movement of the bucket so that, the said material can be piled up, packed and arranged in mounds or dykes or in any other desired manner at the will of the operator of the mechanism.

It will-be seen that the bail 5 is made of a good length and preferably long enough to reach slightly beyond the rear end of the bucket when the tail line is pulled upon, asl

illustrated in Figs. 3 and 4. On the other hand the intermediate member or bar 12 is made comparatively short and preferably somewhat shorter than the length of the bucket, so as to insure the drawing of the real-,end of the bucket quite close to the swinging end of the bail 5 when thebucket is being dumped. I wish it understood, however, that I can vary the proportions ofthe pt 'ts or employ mechanical equivalents thereof without departing .in the least from the spirit of the invention.

Having now described my inventionl what of slack in the tail line 9.-

I claim as new and desire to secure by Letters Patent.y is l l. fr scraper bucket comprising,` a scraper, a head line connected to one end thereof. a tail line connected to the other end thereof, a movable member interposed between the two lines, and haring a pivotal connection with one of said lines and engaging the said running; end of the movable member,

.may move close to the scraper te effect the dumping thereof and mayinove away therefrom to permit of the scraping,` operation.

2. .A scraper bucket comprising a scraper open at one end, a head line connected with the open end of said scraper, a tail line connected with the closed end of the scraper, and a connecting bar having, a pivotal connection with the head line and a traveling engagement with the tail line to secure cooperating movements in the said lines for operating the bucket.

3. A, scraper bucket comprising a scraper open atone end, a bail connected with tie open end of the srraper, a head line connected with the bail, a tail line connected with the closed end of the scraper, and a pivoted bar member carried by the Ibail and movably engaging the tail line for maintaining given relations between the said head and tail lines. v

4L. fr bucket scraper comprising a bucket proper pulling said bucket and connected with a pulling line, a tail line connected with the closed end of the bucket, and a movable member carried by the bail and engaging the tail line, the said member' being` shorter than the bucket, so as to effect the dumping of the bucket when both lines arev pulled upon simultaneously.

5. A scaper bucket comprising a scraper open at one end and slightlyT rounded upon the bottom, a bail pivoted to the open end of the scraper and connected with a head line, a tail line connected with the closed end of the scraper, a movable member pivoted to the swinging end of the bail and a pulley carried by said member and engaging said tail line, the said'member being short enough to effect the dumping,` of the bucket when both linesv are pulled upon simultaneously,

In testimonywhereof, I have hereunto set my hand, in presence of'two witnesses.
