Accordingly it is necessary that crossing tunnels be closed offone from the other and belt conveyors in such crossing tunnels be enclosed to reduce tire and explosive hazards. Previously. this enclosure usually comprised blocking up with cement blocks the entranceways of one tunnel along the sides of the other. and building with cement blocks a complete housing room or tunnel around the conveyor so that it and its crossing tunnel would be substantially hermetically isolated from the atmosphere in the crossed tunnel. Such housings are very inflexible and expensive. and take time to build and tear down. in that mine conveyors are often moved as mining progresses.
Although conveyors have been installed in tubular housings. such housings were either part of the conveyor itself and helped support the belts or flights of the conveyor. or they were only partial housings and did SUMMARY OF THE INVENTION Generally speaking. the conveyor housing of this invention comprises longitudinally split sheet metal tubular sections having outwardly extending flanges along their splits which cooperate with each other so they may be readily clamped together and released. The housing sections are of such size so that they may be readily portable by not more than two men. and may also contain knockout holes for the chains that suspend the two parallel cables between which a mine belt conveyor is supported. These housing sections generally comprise an upper or semi'cylindrical cover section, and a lower or pan shaped section. and the sheet metal therein may be reinforced with circumferential ribs of channel members welded thereto. The upper and lower sections also maybe split longitudinally along their tops and bottoms. respectively. with such split edges overlapping each other and the ends of their arcuate reinforcing ribs telescoping into each other. The ends of adjacent upper and lower sections overlap each other. and between their overlaps and between their flanges there may be provided sealing means. such as gaskets. to make the housing substantially air tight.
One of the sections. and preferably the upper cover section. has provided on its flanges a plurality of sup porting clips which hook over the flange and extend inwardly to space the cover from the conveyor and terminate in hooks which removably engage the parallel conveyor supporting cables along opposite sides of the belt conveyor. Thus. both the weight and natural bowing or springiness of the semi-cylindrical top sheet metal section tend to spread its outer flanged edges and maintain these supporting hooks in engagement with the cables.
On the flanges of the lower sections there also may be provided clips. which clips have outwardly extending knuckles which align with similar knuckles on the upper section supporting clips. which knuckles when aligned may be pivoted together to form a hinge by an axially slidab le pin having a bent end or lever handle for easy assembly and disassembly. Thus when these pins are removed from the clip hinges on one side only of an upper and lower section. these sections may be opened like a clam shell for access to the conveyor and- /orfor cleaning the inside of the housing.
In order to prevent gapping between the flanges of the upper and lower sections. and particularly in the event no gaskets are used between the flanges. there are provided a plurality of manually operated toggle type releasable C-clamps along the flanges. and/or bolts between the flanges. One jaw of each clamp is preferably permanently attached to the flange of one of the sections, usually the lower section. These toggle clamps also may be used for aligning the knuckles of the clip means for their pivot pins.
Accordingly. it is an object of this invention to pro duce an airtight. tire-resistant. portable. easily installed and removed housing for conveyors, which prevent both contamination of the atmosphere outside of the housing from the material on the conveyor and contamination of the atmosphere and the material on the conveyor inside the housing from dust outside the housing. thereby reducing fire and explosion hazards. particularly in mine tunnels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first to FIG. I, there is shown a cross section of a mine tunnel being crossed by another tunnel 22, the atmosphere in which tunnel 22 is isolated from that in tunnel 20 by means of walls or stoppings 24 which maybe made out ofcement block and a tubular housing according to this invention surrounding a belt conveyor 40. This conveyor may comprise a plurality of frames 42 (see FIG. 3) upon which are mounted three belt grooving rollers 44 for the upper run 46 of a conveyor belt for handling material such as coal. and a lower supporting roller 48 for the return run 47 of the conveyor belt. These frames 42 are supported along two parallel longitudinal supporting members 50 which herein are shown to be parallel cables. that are suspended at intervals from the ceiling of the tunnel 22 by means of chains 52 the upper ends of which are anchored to the ceiling by suitable means 54.
The Housing Sections Referring now to FIGS. I and 2, the tubular housing 30 is shown to comprise a plurality of sheet metal sections which may vary from about 2 to about 12 feet in length. but preferably about 8 feet. each of which is split longitudinally so as to comprise an upper section 32 having a semi-cylindrical or inverted U-shaped cross-section with diametrically outwardly extending edge flanges 34. The lower. bottom. or trough pan. U- shaped cross-sectional section 36 also has diametrically outwardly extending edge flanges 38 which cooperate and co-extend with the flanges 34. Thus when the flanges 34 and 38 are held together. the conveyor 40 and its supporting members 50 are enclosed within the tubular housing 30.
In the event the chain supports 52 for the longitudinal members or cables 50 occur along the housing 30, there may be provided spaced knockout holes 35 in the upper sections 32 so that appropriate ones may be used for the chains 52 to extend through. Similar knock-out holes. however. may be provided in the bottom section. if the longitudinal parallel supporting members 50 for the conveyor are supported on standards from the ground. quadracylindrical Arcuately around the outside of each section 32 and 36 there may be provided stiffening or reinforcing ribs ofchannel members 37 and 39, respectively. preferably located near the ends of each section as shown in FIG. 4 to permit overlap of the ends of the sections without interference with the ribs 37 or 39. Such ribs 37 and 39 also may be provided intermediate of the ends of the sections 32 and 36, as required. and as shown in FIGS. I and 2.
Referring now to FIGS. 5, 6 and 7, the upper and lower sections of the housing 30 may also be longitudinally'split along their tops and bottoms to form upper quadrant sections 61 and 62 and lower quadrant sections 65 and 66, respectively. The adjacent edges of the upper sections. and of the lower sections. may overlap as shown in these figures. and may be held together by the telescoping ends of the reinforcing ribs 67 as shown in FIG. 7. Thus each upper and/or lower sections may be composed of two quadra-cylindrical portions for more easily manually handling and assembly, particularly for larger housings. These quadra sections also may be advantageous for covering conveyors which are supported from the floor.
Referring now to FIGS. 8, 9 and 10, there are shown enlarged one of the flange clips 70 employed for the support and spacing of the housing sections on and from the longitudinal conveyor supporting members or cables 50, one of the cooperating hinge flange clips 80, and one of the manually operated toggle flange clamping means 90, all of which may be located along the flanges 34 and 38, as required. Although these clips 70 and may be connected to either the upper or lower housing section flanges, herein and preferably the supporting hook clips 70 are attached to the flange 34 of the upper sections so that these flanges 34 rest on these clips 70. Each clip 70 has a corrugated flange clamping hook end 72, which corrugations bite into the top of the flange 34 to prevent the clip 70 from slipping off the flange. Outwardly from the outer edge of the flange 34, the clip 70 has a hinge knuckle portion 74, and inwardly therefrom a flat flange supporting plate portion 76 ending further inwardly in a cable engaging hook portion 78. These clips 70 are preferably made out of steel. so that when they are forced over the flanges 34 they will engage therewith and will be stressed in tension by the bowing of the upper section 32 and its weight. Preferably these clips 70 are located near each end of each housing section 32, and may also be provided intermediate its ends, if necessary. Thus. these clips 70 are the only support for and connection between the housing 30 and the cables 50, in that the lower sections 36 are attached to the upper sections by their respective flanges 34 and 38.
One means for this attachment of the lower sections 36 to the upper sections 32 are the other flange clips 80, which have similar corrugated flange engaging portions 82; outwardly extending hinge knuckles 84 which are alignable with the hinge knuckles 74 on the supporting clips 70 adjacent thereto as shown in FIG. 8, and inwardly extending housing 36 engaging angle portions 86, to further prevent slipping off of these clips from their flanges.
On the upper and lower sections 32 and 36, respectfully. are fastened or clamped together such as by the clamp to be described later, and the hinge knuckles 74 and 84 are aligned. a pivot pin 88, which may have an L-shaped handle end 89 (see FIG. 1) may be manually slid through these knucles 74 and 84 to act as hinges between the upper and lower sections. Then when the pins 88 are removed from the clips 70 and 80 only along one side of the sections 32 and 36, and all the clamps 90 or bolts between the flanges 34 and 38 are disengaged. the lower section 36 may be swung downwardly as shown in one of the dot-dash lines in FIG. 3, so that access can be had into the housing 30 for cleaning thereof. such as with a hose, both the open sections as well as those adjacent thereto. This is particularly the case if the adjacent sections have their flanges bolted together by bolt 100 as shown for the end sections in FIG. I that are also anchored into the stoppings 24.
In addition to the clip means 70 and 80, or bolts 100, there preferably is also provided manually operated toggle type C-clamps 90, shown specifically in FIG. 10. These clamps 90 may be of standard construction each comprising a pair of handle levers 91 and 92 that operate through pivots to link 93 and to clamping arm 94 having a threaded adjustable jaw bolt 95 which clamps the upper flange 34 against the lower flange 38 supported by lower jaw 96 fixed to the handle member 91. This lower jaw 96 may be fixedly attached to the lower flange 38, so that these clamps 90 will not be lost. This attachment may be by welding a flange reinforcing plate 97 to the jaw 96 and then welding this plate 97 to the flange 38 as shown in FIGS. 9 and l0.'A plurality of these toggle clamps 90 may be provided along the flanges 34 and 38 as required to prevent gaps between the flanges.
If the clamping of the flanges 34 and 38 is not sufficiently air-tight, there may be provided a sealing means such as gaskets 105 shown in FIGS. 9 and 10, between these flanges. Similar sealing means also may be provided between the overlapping end edges of the sec tions, if needed.
In the event there are gaps or spaces which permit the escape of too much air, these may be clogged with a foam plastic material, such for example, in the gaps around the knock-out holes 35 provided for the chains 52.
Accordingly it is to be understood that although the particular detachable conveyor housing of this invention is shown adapted to a suspended belt conveyor 40, it also may be employed for covering the other type conveyors supported on the floor or by other means, whether these conveyors are inside or outside of a mine.
While there is described above the principles of this invention in connection with specific apparatus, it is to be clearly understood that this description is only made by way of example and not as a limitation to the scope of this invention.
