OPEN-TYPE BUCKET r03 nxcAvA'rrNe-MiicrirNEs.
. Patented Ma 9, 1915.
Application filed November 5, 1913.- Serial No. 799,281).
To all whom it may concern:
Be it known that I, FRANK J. MONAHAN, citizen of the United States, residing at J oliet, in the county of Will and State of Illinois, have invented certain'new and useful Improvements in Open-Type Buckets for Excavating-Machines, of which the following is a specification.
My invention relates to improvements in trench digging machines, and especially to a form of a so-called open type bucket adapted to be used in connection with said machines, and has for its chief object, the provision of a bucket that will be capable of digging itself free in case of a cave-1n, and that will be automatically disconnected from the conveyer chain to which it is connected if a rock bed is struck, thus eliminating the damage that would otherwise be caused to the engine'driving the mechanism.
Another object of my invention is the provision of digging teeth for the bucket, that 1 are extremely strong and that can easily be replaced in case of their being broken or dulled.
Other objects and advantages of my invention will be apparent to those skilled in the art and need not be specifically set forth herein.
In the accompanying drawing forming a part of this application, I have illustrated a preferred form of my invention 1n the following views:
Figure l is a top plan view partlally 1n section on line 11 Fig. 3, a portion of the top wall of my'bucket being broken-away so as to disclose the various transverse parsame consisting of a casting having the horizontal tapering and pointed front edge or nose 5*, and the two sides or vertlcally d1s.
posed cutting edges 5 which rise above the main portion of the bucket. The rear edge is recessed at 5, so as to make a clearance for the. conveyer chains (not shown) when the bucket is rounding the ends of its course. Back a short distance from the front edge 5, and'extending downwardly, is a front vertical-wall{5 and. spaced from that is a rear wall 5 both .of whichextendlongitudie nally the length of the bucket and parallel to the front edge of same. Transversewalls 5, divide the area between said walls 5 and 5, and at thetwo extreme ends are similar walls 5 at a slight angle to said walls 5 and 5", for the purpose hereafter to be described.
I 6 represents teeth substantially rectangular in cross-section, the upper and forward edges 6 of whicharetapered and sharpened. Said teeth areinserted through inclined recesses 5 in the body of the bucket5, their lower ends resting upon the shoulders 5 on the wall 5 as clearly shown in Fig. 4, and between the walls 5, and are secured in place by cotter pins 7, passing through said walls 5, and the pins 6. At the two ends, where the walls 5 are inclined as described, the teeth 6 are held at an angle, and protrude slightly beyond the sides of the bucket.
Spaced apart, one near each end of the bucket, as clearly shown in Fig. 1, are two circular apertures surrounded by a raised boss 5 respectively, on the under side ofthe bucket, and through which are adaptedto extend lugs 8 of arms 8, respectively. Said arms 8 extend upwardly and are formed with bosses 8", which are adapted to register with the extensions 9*, of the chain link 9, to which they are secured by the rivets 10. Cotter pins 11 passthrough the rear walls 5 and then through the :lugs 8", thus rigidly securing said arms 8 to said bucket 5.
The bucket just described is adapted to be Z used in connection with the endless chains now commonly used, only instead of the bucket doing the digging, the teeth 6 accomplish this work.' Said buckets are spaced substantially two or three feet apart on said chains, and in case a very wide trench or ditch is being excavated, the end teeth-6 can be removed, and several buckets may be hooked up abreast one another on their respective chains- In 'case a bed of impenetrable rock is struck during the operation of digging, the cotter pins 11 will be sheared off, thus relieving any sudden shockor strain on the engine used to drive thechain, which might result in serious damage to the entire machine if means such as the cotter pins were not provided.
Having thus described my invention, What nally the length of said bucket, and below or under said 'face, a series of transverse walls dividingthe space between said front and rearwalls intocompartments, a series of teeth sharpened at their outer ends;
, adapted to pass through apertures in the face of saidbucket and protrude forwardly therefrom, the lower ends of said teeth abut ting against shoulders in said rear .wall, cot- I ter pins passing through. said a transverse walls and said teeth,: and arms having lugsu which pass through said bucket, and .cotten pins passing throughlsaid lugs, said *arms being adapted to be secured to the chainof:
said machine.
In testimony-whereof I aifix my signature in the presence of two witnesses. FRANK J MONAHANL Witnesses: 1
