MECHANISM DISINTEGEATING DISLODGED MATERIAL.

Application aieasepie'mber ao, i921. serial No. 502,036.

rl`he invention relates to means foi-'disintograting or breaking up material Which after it has been preliminarily dislodged or dejected is still inrtoo compact a mass for power shovel', for instance.

Qbjectsland advantages of' thev invention will beset li'ort-h in part hereinaiiterand in part will be obvious herei'rom, or kmay be learned by practice vvith the invention, the same being realized and attained by means ot' the instrumentalities and combinations pointed out in the appended claims.

Theinvcntion consists in the novel. parts,

constructions, arrangements, combinations and iniproven'ients herein shown and described. v

The accompanying drawings, `referred to herein constituting a part hereof, illus` trate one embodiment of the invention, and together with the description, serve to explain the princililcs ofthe invention.

condition for most eilicient handling. lt is also desirable that 'the preliminary dislodgnient be very gentle so as to avoid breakage, and further Vdisintegration is `required for later eiiicient handling. The present invention is intended to permit the material to` be dislodged under the most favorable'y conditions and to then gradually disintegratethe dislodged material so that it can be handled under Ythe most favorable andeirlcient contion Vvvith the mining of such coal and then acts on the coal toprepare itfor expeditious and eiiicient removal, as by a loading machine or povver Shovel. l, y

When so acted upon, the coal is in favorable condition for being conveyed away for instance, by the loading machine ofrny copending application Ser. No. 247,24),liled July 29, 1918. l Accordingly, the invention is -sliovvn applied to the mining of `coal,althoingh ,it will be understood that the description of this particular application is exemplary and r`latery and is'not restrictive of the invention. l y Y Referring novv to the present preferred embodiment ot the invention, illustrated by Way of example in the accompanying dravvings, a lovT and 'Hat frame is provided, adapt .ed to lie beneath a mass of undermined material. as for examplein van undercutvkerf beneath a mass of coal preparatory to its dislodgment. y

@ne or more projectors are carried either directly or indirectly onsaid frame and means are provided for forcing or projectine. these projectorsupvvardlv into the mass et dislodged inateriahvvhereby it is exten sivelv vet l.f iently further disintegrated asthe vdevice is drawn outwardly and thus'prepa-red hv newer, and pra ctically instantaneously. ter hia'linoj.L A. plurality' ofthe devicesA are preferably employedtogether, and are dra-Wn Y:cattiveria navrs, or' sr.v Bannister, PENNSYLVANIA, assrenon, BY MFSNE Assreivlll feo

out simultaneously, and act together' on the dislodged mass of material in the manner described. Other features of the invention will be first described in connection with the following detailed description.,

Referring now in detail to the embodiment illustrated in the accompanying drawings, the frame of the device consists of a channel 1, which is low, flat and long, and has its back 2adapted to lie on the ground, or on a mine or quarry floor, and the two side fianges 3 and 4; of the channel extend upwardly at either side and are utilized to mount or Support other parts of the device.

A member or plurality of members, which may be conveniently .styled projectors,'are

mountedon the frame in a convenient manner andareadapted to be projected upwardly into the mass of dislodged and dejected ma- Vterial, so that by drawing the device outward ly the mass of material will be further disin tegrated.

As embodied, the projector or projectors are incooperative relation with the means for drawing the device outwardly. A bar 5 lies within the channel 1, resting upon the bottoni 2 thereof audit is preferably considerably narrower than the channel. Movably mounted on the frame are sho-wn two projectors 6. Asingle description will be sufficient.

The j projector is preferably pivo-tally imounted and as embodied consists of a generally U shaped or three-sided member nar rower than, and lying within the channel bar 1, and having apertures near the two open ends, and also near one side thereof, as best appears from Figs. 2, 3 and 5. The projector is pivotally mounted on the frame by means of rod 7 extending between and mounted in the sides-3 and 4 of the channel bar 1 The projector or Vprojectors comprise the two Iside reaches 8 and 9 and the front or cross reach 10. The cross reachv 10 isjpreferably shallower or narrower' than theside reaches, and across the top thereof there is formed an upwardly and -outwardly .extending flange 11, designed to assist in engaging the dislodged mass to lift vor swing the projector upwardly asV the bar 5 is moved during the pulling outwardly of the device. j

Theembodied form of actuator for the projector comprises a cam 15, fastened upon the upper face of the bar 5 in any suitable manner, as by means of screws 16. A stop, .such as a rod or bar 18 mounted in the sides 2 and Stof the channel, is provided against which the front of the cam 15 impinges to stop the forward travel of the bar 5 relatively to the channel, and to thereby cause the pull on the vbar to move the entire device. In addition to the upward impulsion of the flange beyond the front end of the channel and has means for attachment of a drawing cable,

such as the hole 19 formed in the bar.

As embodied, a motor 2() is utilized to draw out the device from beneath the dislodged and dejected mass of material, the motorY being provided with a winding drum 21, upon which is wound ak cable 22, whichhas a hookV 23, hooking into the hole 19. The motor is anchored ina suitable manner, as by being ly to disintegrate an entire large dejected mass at one time. In Fig. 7 all the disintegrators are shown connected to a single winding mechanism, although this may be varied in any convenient or Vdesired manner. A hole 28 is shown in Fig. 6 for blasting powder or other disinte-grating and dejecting means.

In Fig. 8 the mass is shown dejected and preliminar-ily disintegrated, the disintegratingl devices being in the position of Fig. 6, with the projectors 6 lying down within the channels 1.

In Figs. 7 and 9 the pull'hasbeen exerted on the disintegrators. Thereby the bar 5 has moved outwardly, or to the left in Figs. 6 and 8, and the projectors 5 have been' pushed upj wardly into the disintegrated mass fronithe position of Figs. 6 and 8 to that of Fig. 9 by the action of cam 15 on the projector 5 (the two positions being shown in detailin Figs. 3 and 5, respectively). j

The continued pull after the projectors have been forced upwardly will further effect the disintegration of the whole mass, as approximately and somewhat diagrammatically shown in Fig. 9. In coal mining this action will Vleave the coal in condition to be operated on eiliciently bymy loading machine hereinbefore referred to, while permittingY such a gentle dejection and `preliminary disintegrationas will yield a relative maximum Y of large pieces of coal. e Y

The invention in its broader aspectsl is not limited to the specific mechanisms shown and described but departures may be made .theret from within the scopeV of the accompanying claims without departing from they principles of the invention and without sacrificing its chief advantages.
