This invention. relatesto a dust/barrier and it is an object of the. invention to provide: a device of this. kind adapted "tor'usev within a mine and which operates automatically to createa dust cloud to prevent thepropagas tion of an explosion. i a
The invention also hasiiior an .objec'tto ro vide an apparatus of this kind which autcv matically becomes effective. upon am explosion within a mine passage and which-.appar ratus when. efiective creates; a.-clo.ud. of dust of shale or other inert material to prevent propagation of such explosion.
An additional. object. of the: invention is to provide an apparatus of thist.-inclsuding a plurality of suitably positioned ireceptacl'es containing a supply of inert dust, such as shale, together withmeans associated with saidreceptacles. op eratingautomatically as a result of an explosion to re' easeg said dust.
The invention consists :in the detailsaoii con:- struction and in the combination and arrangement of the several parts-of: my improved dust. barrier whereby certain portant advantages are attainedwand-the device rendered simpler, less expensive and Y otherwise more convenient:andadvantageous for use, as will be hereinafter more: .ful'ly'set forth. 7
The novel features of my invention will hereinafter be definitely claimed.v
In order that my invention may be; the better understood, I will now proceed to describe the same with reference-to the 31660111: panying drawing, wherein r Figure 1 is a view in side eleva-tion: of somewhat a diagrammatic character illustrating barriers constructed in accordance with an embodiment of my invention: ill-up:- plied position;
Figure 2 's a fragmentary view in: top plan of one of the devices as herein disclosedigf Figure 3 is a sectional view taken substantially on the line 33 of Figure 2'; Figure 4 is a sectional ew taken substantially on the line- 4.4: of Figure 2:; Figure 5 is a sectional view taken substantially on the line 5-5 of Figure 2; Figure 6 is an enlarged fragmentaryfsectional view taken on the same line as-3'--3-; Figure: .7 is; a iiragmentary View in bottom plan of the cylinder .QiECl pQRfSBd-lIXQI-Ztly associated. therewith.
- Figure 8-is an -enlarged fragmentaryeleva as ti'onal View takenat one. end portion of one of the apparatus, as herein disclosed Figure 9 'is a fira'gmentary View at top I plan of the structure illustrated in EigurerSi;
' Figure; 10-isa sectional view taken-issaibs no stantiail'ly on the line l0-,10-of.Figure"8. f
. As illustrated. inv Figure 1:, two apparatus A and "constructed accordance with an embodimentv of "my invention are suitably positioned within the passageway of mine,
the apparatus B being termed whatis known as a"repea ter and is positioned preferably at aapoint within: the passagewayh igher-than thatoithe apparatus r,
These two apparatus are duplicate in? construetion but reversely' arranged, the-apparatus B intending to become effective in th'e .e-Ivent ot a second explosion or: itlareeha'ck. Each ofthewapparatusA andB-isoiiazny preferred: dimensions and includes; as man dust receptacles as the requirements of practice 'maydictatez a As disclosed in the accompanying draw .izngsi, each of. the apparatus. A. and conip-rises: side members which, at predeterrmined points. spaced? l'ongitudinallythereot, are connected. by" the "cross. members 2 each disposed on a lateral incline with respectht'o the vertical. or the plane occupiedhy the side members: .11. 'Each of these "crossmembers 2 constitutes a wall for a dust receptacle and enacting with each .ofthese'cross members or wallsfizis a swingingwal-l3iwhiclnwhieni closed with respect to the member or Qt is Ein clined upwardly from" the lower end oith'e member or wall 25in a direction therefrom. Withxthe-wafillg closed areceptacleisprovided adapted to contain a supplyiofsuitableuinert dust; such as dust? J I The upper marginal} portion oi? eaehofi the walls or plates; 3-:is provided withhook-il-i l're members 5 whereby'the :maybepitotal- 1y suspendedtrom across bar or rodifiibridgiii-1g the. space between the side. members 1 and resting thereonv from above. The upper rto.
surfaces of the members 1 are provided with transversely disposed grooves or channels 7 which receive the end portions of the bars or rods 6. Coacting with such end portions of the rods or bars 6 are the retaining or holding latches 8 herein disclosed as pivotally connected intermediate their ends, as at 9, to the upper edgeface of the side members 1.
The lower longitudinal margins of all of the walls or plate 3 are operatively connected, as at 10, with the transversely spaced parallel bars 11, said bars being connected by an end cross members 12. Substantially midway its ends the cross member 12has secured thereto an extremity of a coil spring 14 of desired tension, the opposite end portion of which being operatively connected to an end portion of an'elongated arm 15.
The end portion of the arm 15 remote from the end member 12 terminates in a lateral'e-xtension or lip 16 which, when the walls 8 are in their closed or normal positions, is inserted from below up within a holding cylinder 17. This cylinder 17 is operatively supported by alower cross member 18 suitably secured to 21 slidably placed within the cylinder 17.
The upper end of the cylinder 17 is provided with a cross bar 22 and interposed between this bar 22 and the inner end of the plunger 21 is an expansible member 23 of desired tension and which is herein disclosed as a coil spring. When the plunger 21 is retracted within the cylinder 17, the member or spring 23 is placed under tension and the plunger 21 is maintainedin such retracted position by a rock arm or trigger 24 engaging the lug'20 from below. This rock arm or trigger 24 is carried by a shaft 25 rotatably supported between the side members 1.
The shaft 25 also carries a depending wing 26 which, under the force of an'explosion', will swing in a direction to release the trigger 24 from the lug 20 whereupon the plunger 21 will be forced downwardly for contact with the extension or lip 16 free of the cylinder 17 whereupon the weight of the dust within each of the receptacles will swingithe wall 3 of'such receptacleinto open position to permit-release of the' dust therein. 1
As the dust drops it passes through a screen fabric 27 underlying the various receptacles andwhich serves to assure an effective distribution of the dust to create a cloud which will resist propagation of an explosion.
The repeater apparatus B, as before stated, is positioned above or higher than the appainafter' claimed.
.ratus A and the apparatus B is intended to be effective upon a second explosion or flareback or return of the force of the first explosion. By the use of the two apparatus the force of the explosion is caught on both sides, that is to say, going up the passage and coming back.
Each of the wings 26 has connected thereto as at 28 the extremity of a flexible member or chain 29 which is also secured as at 80 to the member 31 depending from the apparatus. These chains or flexible members 29 coacting with the wing 26 in the apparatus B are two in number, while in connection with the wing 26 in the apparatus, only one is used,
and provide effective means for limiting the also be obvious that my invention is susceptible of some change and modification without departingfrom the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying practice except'as hereout my invention in I claim 1. A dust barrier apparatus comprising a dust receptacle having a movable Wall movable intodust releasing position,amember operatively engaged with the movable wall and engaging the cylinder to hold the movable wall in closed position, a plunger working within the cylinder, means for holding the plunger retracted,said holding means ineluding means operating-under force ofan explosion in one direction to release the plunger and preventing release of the plung er under force of an explosion in the opposite direction, the plunger when released disengaging the member from the cylinder, and means for normally urging said plunger toward said member.
2. A dust barrier apparatus comprising a dust receptacle having a movable wallmovable into dust releasingposition,a member operatively engaged with the wall and engaging the cylinder to hold the movable wall in closed position, a plunger working within the cylinder, means for holdingthe plunger retracted, means for normally urgcarried by the shaft and coacting with the plunger for holding the same retracted, an operating wing carried by the shaft, and means for holding said operating Wing against movement in one direction, movement of the Wing in the opposite direction effecting release of said holding means, release of said holding means permitting movement of the plunger toward the member to release the member from the cylinder.
