provements in Holding Chairs for Rails,

- of which the following is a specification.

It is the purpose of the present invention to provide, in a holding chair for rails particularly in mines, a construction wherein the retaining parts or elements are capable of freedom of movement when it is desired: to remove the rails from their holding po sitions in the chair.

Another purpose is to provide a holding chair for the reception of a track rail, to-

' gether with a rail section disposed on its side and in engagement with the chair with its ball engaging the side of the web under the ball of the-upright rail, together with a wedging key to hold the clamp detachably n place on the'track rail and yet permit free adjustment of the rail section without releasing the clamp from its position on the track rail. i

A still further purpose is to provide a holding chair wherein a rail section may be inverted so that its ball may engage the base of the upright rail instead of the web, there being means provided on the chair for retaining the inverted rail section in an in verted position, while permitting longitudinal adjustment of the same. i i

It is to be understood that the particulars vherein given are in no way limitative and that, while still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to the circumstances.

The invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed. 1

Figure 7 is a detail view of thechair shown in Figures 5 and 6.

Referrlng to the draw1ngs,1 designates a holding chair for the reception of an upright rail-2. The chair, has a seat 3 with which the base of the. upright rail engages, there being a flange 4 rising from the seat and overlying the base 5, of p the :upright rail. 'Tjhe chair opposite the flange 1 has a wall 6 which overhangsthe seat of the chair. The under, surface 7 of this wall isinclined and engaging therewith is a key 8. The under surface 7 ofythe wall is not only in clined toward the bottom of the seat but it is also inclined or angularly disposed rela tively to the base of the upright rail. M

- The key 8 is tapered throughout itsleng th, therefore has a wedging action with the sur face 7. The key 8 also has a shoulder 9 to engage with a portion of the wall 6 to limit the keyin its position when engaged with gagement with the flange 4, to sec-urely'look the chair clamptothe base of the upright or fixed rail. r

An extension rail section 11 is provided and constitutes a guard rail for the upright rail. This rail section is disposed on its side, in fact, so that its ball 12 engages with the web of the uprighttrack rail under the ball. The holdingchair has an upstanding flange 13 withwhich the rail section 11 engages to retain theball of the rail section under the hall of the upright rail and in engagement with its Iweb'and its base. A slight space intervenes between the flange 13 and the base of the rail 11 which permits the rail 11 to he slid longitudinally to project the end of the extensionrail farther from the. fixed rail without releasing the clamp 1 from the fixed rail, the length of the flange 13jbe ing such that whenthe. head 12 of'the rail 11 isag-a inst, the rail 2 thefsidewise move 7 rail.

mentor spreading of the rail 11 is substantially prohibited.

The holding chair is provided with an eye 1% to which a chain15 is'connected, the chain being, inturn, connected to the key so as to prevent loss thereof.

In Figures 5, 6 and 7, the'construction of the holding chair is substantially the same as that in Figures 1 to i, inclusive, with the exception that the rail section 16 is inverted so that its ball 17 may engage with one side of the web or the upright rail 18 adjacent its base. Also inthis construction, the upstanding flange 13 has a lateral part 19 which engages withthe web of the inverted rail and acts to retain the ball 17 of the rail 16in engagement with the base of the up right rail. In this construction, the base of the inverted rail section not onlyacts as a guard but also acts as means to insure against outward deflection of the upright The holding chairin addition to'eonstituting the support to hold a rail sectionfon the side of an upright rail as a guard also constitutes means to support arail section in position (mas side or inverted in order to be convenient at all times for the purpose of temporary or permanent extension of a mine track.

Naturally, as the coal is dug away from the wall of a mine, the space between the end of the mine track and the wall; in

creases and at times it is necessary to provide atemporary extension of the track be fore the extension is made permanent, hence it is necessary tohave rail sections close at hand in order to make a temporary or a permanent extension of the track, so that the mine cars can come closer to the wall from which the coal is removed. I

IVith this idea in view, the presentinventionaims to provide a holding chair which is clamped to the permanent track rails (which are spiked down to the ties). The holding chair is clamped to such upright spiked down track rails by means of the wedge, the wedge engaging on one side of the base of the upright raliland the flange 4 overlying the opposite side. In order that the holding chair may provide a support for a rail section so that it will at all times be close at hand, the chair is provided with an angular extension, the upright wall 13 of which acts to retain the rail section 11 in a position on its side with its ball 12'under the ball of the upright rail and resting upon the base thereof.

It will be noted that there is sufiicient space between the base of the rail section 11 and the wall 13 so that the rail section 111 may have free movement so that it may be easily inserted andremoved or extended by sliding the same the full length of the up right ai 12+ 1 s he n 1 sec-tier;

the rail section 11 is removed 16 is inverted and is looselysupported for free movement between the upright rail and thelateral part19 of the wall 13. When the rail section 16'is so disposed, it may also constitute an abutment for the car wheels.

As previously stated, the upright rail section 2 is designed to be spiked downand stationary to the ties. The holding chair is applied, in fact, two of them may be used on'the upright rail 2, although only one is illustrated. The two chairs are disposed in position on the upright rail a distance approximately equal to the length of the rail section 11 which is to be disposed upon its side. The chair is secured fast to the upright rail 2 by driving the wedge or key 8 between the surface 7 of the overhanging wall 6 and the base of the upright rail, so that the wedge may be clamped upon the upright rail base on one side with the flange 1 on the other side. This holds the chair securely in position.

It is possible to slide or slip the rail section 11 between the web of the upright rail and the wall 13 of-the chair. This rail section 11 may have free movement "back and v forth the length of the upright rail. lVhen or slipped out of its position its full length, the wedge or 'key 8 may be removed, permitting detachment of the chair. The rail section ll'can then be turned to an upright position and spiked down. The holding chair may then be applied to the last spiked down rail section, that is, the rail section which has been removed from theposition on its side to an upright position. Another rail section is then disposed upon its side or inverted, as in Figures 1 and 5, and slipped loosely in the holding chairs, so that this rail section may at all times be close at hand in order toconstitute a part or a section of the track when it is desired'to extend the mine track.

In order that a rail section which is disposed upon its side or inverted can have freedom of movement when supported upon its side, the space between the wall 13 and the upright rail is greater in width than the height of the rail section in order that said rail section may have free movement, whereby it can be slipped from the end of the upright rail to full length of the rail section which is disposed'upon its side withoutremoving thekey.

It is to be borne in mind that the spaces between the ball of the upright rail 18, the part 19 and'the web of the inverted rail and the'space between the base of the rail section 11 and the part 18 are merely illustrative of the fact that the inverted rail sec 151011. 16 a the t il adi s 21. r p e a of freedom of movement and not that-such rail section should not engage the ball of the upright rail and the parts 13 and 19. In other words, the inverted rail section 16 and the rail section 11 should be inserted in positions in actual practice, so as to engage with the upri ht rail and the part 13 and yet be capable of freedom of movement in order to permit the inverted "ail section 16 or the rail section 11 to be easily inserted manually without using any extra power or exertion.
