Application April 23, 1953, Serial No. 350,557

11 Claims. (Cl. 61-45) This invention relates to a pre-fabricated, telescoping, and easily installed stopping and has for its particular object the provision of salvageable means for use as an air stop in mines.

The construction of this invention features the use of a plurality of telescoping panels of variable widths and lengths adapted to be resiliently secured to Whalers an chored in the rib of coal or material being mined in such manner that when the mine bottom is subject to a squeeze the resulting displacement of various portions of the bottom will not buckle the stopping but the panels will telescope to maintain a satisfactory air stop.

Stopping now used in mines is for the most part constructed of cement blocks permanently secured in place. This is unsatisfactory due to the fact that this installation is very costly and completely unsalvageable even when there is no longer any purpose for the stopping. Furthermore this masonry stopping may crumble when the mine is subject to an upheaval or squeeze Accordingly, it is the primary object of the invention to provide a readily salvageable mine stopping capable of being speedily erected at a comparatively low cost.

Still further objects and features of the invention reside in the provision of a mine stopping that is strong and durable, capable of being installed by even semi-skilled labor, constructed from a minimum number of parts, which is easily caulked for complete prevention of ow of air, yet which may be easily disassembled.

These, together with the various ancillary objects which will become apparent as the following description pro-I ceeds, are attained by this stopping, a preferred embodiment of which hasbeen illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is an elevational view showing the stopping comprising the present invention as installed;

`Figure 2 is an enlarged horizontal sectional view as taken along the plane of line 2 2 in Figure l;

Figure 3 is a vertical sectional view in an enlarged scale as taken along the plane of line 3--3 in Figure l;

Figure 4 is an enlarged sectional detail view illustrating the use of an overlapping panel used to complete the Stopping;

Figure 5 is a sectional view illustrating the construction of the clamping means used to resiliently hold the panels against the horizontal support bars or whalers;

Figure 6 is a perspective view of the clamp used in holding the overlapping panel in position;

Figure 7 is an exploded perspective view illustrating the configuration of the telescoping portions of a panel;

Figure 8 is a perspective View of the clamping means used in holding the panels to the whalers; and

Figure 9 is a perspective view of a spring plate used in holding the panels in abutting engagement with each other.

With continuing reference to each other wherein like reference numerals designate similar parts throughout the various views reference numeral 10 is used to generally indicate the stopping comprising the present invention and adapted to be used in an air stop in a mine having a top ICC 12, a bottom 14 and ribs 16. The stopping 10 includes angle shaped Whalers or support bars 18 and 20 the ends of which are embedded in the rib 16. The support bars are preferably each formed out of three sections which overlap each other, the sections being designated 18a, 18h and 18e, and 20a, 20h and 20c respectively. The intermediate sections 18b and 20b overlap the end sections permitting use for various sizes of stopping.

The Whalers 18 and 20 are substantially horizontal and are positioned in parallel relationship to each other and are adapted to provide means for supporting the plurality of pairs of telescoping outer and inner panels 22 and 24 respectively. It is to be noted that the pairs of panels are arranged in side by side abutting relationship and alternately the inner panel is the upper and lower panel. This because this arrangement permits the panels to intermesh to the greatest extent decreasing the air space therebetween thus reducing the amount of caulking 25 necessary. Each of the panels 22 and 24 are substantially channel-shape having fr ont walls 26 and 28, rearwardly ,z extending portions 30, 32 and 34, 36 and inwardly converging L-shaped flanges 38, 40 and 42, 44 respectively.. As best seen in Figures 2 and 9, there are provided arcuate spring-like plates 46 of somewhat greater length than the width of the front Walls 26 and 28 which are adapted to resiliently urge the sheet metal rearwardly extending portions into intimate engagement with each other.

in order to hold the panels 22 and 24 against the whalers 18 and 23 there are provided clamping means comprising substantially U-shaped plates 48 having threaded rods 50 press fitted therein. The rods 50 extend through the whalers 18 and 2i? and the U-shaped plates 48 engage the LShaped anges in such manner as to resiliently hold the panels 22 and 24 in engagement with the Whalers 18 and 2th The rods 5t) have thereadedly secured thereon nuts 52 which engage the whalers 18 and 20. The precise by suitable wires 60 or any other type of fastening means.-

This permits the sealing of the top and bottom of the stopping 10 especially since the panels will telescope to conform to the contours of the top 12 and bottom 14.

In the process of assembling the stopping 10 the panels are preferably erected starting at one side or rib' 16.

v The panels are, as heretobefore defined, arranged in abutting relationship. However, due to the irregularities in the dimensions of the mine, the panels can seldom be positioned so as to complete the structure without neces; sitating the use of overlapping pairs of panels 22p and 24p. Actually the panel at the other side is placed in position and the penultimate panel 22p and 24p is then placed in position with the outer surfaces of the flanges 38p, 46p and 42p, 44p abutting the two spaced panels as can be best seen in Figure 4. The clamp having central connecting portions 62 interconnecting legs 64 and 66 is positioned with a threaded shaft portion 68 extending through the whalers 18 and 20 and with the legs 64 and 66 engaging the inner surfaces of the L-shaped anges 38p, 40p and 42p, 44p. Clamp fixtures 70 engageable However, should an explosion occur in the mine, the door formed by the plate I6 will open permitting equalization of pressure.

For further rigidifying the structure, braces 8G are bolted to the whaler 18 at one end thereof. The other end of the braces 80 are secured by expansion fasteners 32 to the top i2, the braces extending angularly upwardly from the Whaler 18.

Since from the foregoing, the construction and advantages of this mine stopping is readily apparent, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modincations and equivalents 'may be readily resorted to which fait within the scope ofthe appended claims.
