lllllll l l ll wedge, may then be locked in the desired position of adjustment by means of the lock nut 21. In the event of fire, the effect of the heat will cause the fiber washer 17 and the fiber wedge '18 to burnout or become disintegrated, thereby releasing the metal bearing block and thus preventing bindin of the door when thent-he metal parts of the door or door guides expand due to the heat of the fire.

It is noted that any desired number of guide shoes may be secured to the side rail of the door, two shoes being ordinarily used on each side of the door.

The hereinbefore described arrangement admits of considerable modification, and I do not wish to be limited to the precise arrangements shown and described.

What- I claim is:

1. The combination with a frame member and a sliding closure member therefor, of a guide for the sliding closure member, said guide being secured to one of said members in position to cooperate with the adjacent edge of the other of said members, a bearing block mounted on said guide bet-ween the op posing faces of said members, and means for adjusting said block towards and away from said opposing faces to take up wear and to obtain the desired play therebetween.

2. The combination with a frame member and a sliding closure member therefor, of a guide for the sliding closure member, said guide being secured to one of said members in position to cooperate with the adjacent edge of the other of said members, a bearing block mounted on said guide between the opposing faces of said members, means for adjusting said block towards and away from said opposing faces to take up wear and to obtain the desired p'lay therebetween, and means for securing said block in the desired position of adjustment.

3. The combination with a frame member and a sliding closure member therefor, of a guide for the sliding closure member, said guide being secured to one of said members in position to cooperate with the adjacent edge of the other of said membens, a bearing block mounted on sa d guide between the opposing faces of said members, means for adjusting said block towards and away from said opposing faces to take up wear and to obtain, the desired play tiherebet-ween.

means for securing said block in the desired position of adjustment, and means whereby the securing means for said bearing block is adapted to be released by exposure to fire.

4. The combination with a frame member and a sliding closure member therefor, of a guide for the sliding closure member, said guide being secured to one of said members in position to cooperate with the adjacent edge of the other of said members, a bearing block mounted on said guide between the opposing faces of said members, means for adjusting said block towards and away from said opposing faces to take up wear and to obtain the desired play thcrebelween, means for securing said block in the desired position of adjustment, and means whereby the securing means for said bearing block is adapted to be released by exposure to fire, said block adjusting means being combustib'le, whereby it is adapted to become disintegrated by exposure to fire.

The combination with a frame member and a sliding closure mcn'ibcr therefor, of a guide for the sliding closure memlua', said guide being secured to one of said mcn'ibers in position to cooperate with the adjacent edge of the other of said members, a bearing block mounted on said guide between the opposing faces of said members, and means for adjusting said block towards and away from said opposing faces to take up wear and to obtain the desired play thcrcl ctwccn, said block adjustingmeans being combustible. whereby it is adapted to become disintegrated by exposure to fire.

6. A guide shoe for vertically slidable lire doors comprising a bracket member adapted to be secured to the side edge of-the door and having spaced guide flanges adapted to straddle a guide rail for said door, a. bearing block supported between said guide flanges for sliding movement towards and away from said guide rail, and a wedge for forcing said block in the direction of said guide rail.

7. A guide shoe for vertically slidable lire eoors comprising a bracket member adapted to be mounted between the side edge of the door and a guide rail for said door, a hearing block mounted on said bracket member for sliding movement towards and. away from said guide rail, and a wedge for forcing said block in the direction of said guide rail. 7

8. A guide shoe for vertically slidable fire doors comprising a bracket member adapted to be secured to the side edge of the door and having spaced guide flanges adapted to straddle a guide rail for said door. a bearing block supported between said, guide flanges for sliding movement towards and away from said guide rail, a wedge for forcing said block in the direction of said guide angle, and means for locking said block in the desired adjusted position.

A guide shoefor vertically slidable fire doors comprising a bracket member adapted to be secured to the side edge of the door and having spaced guide flanges adapted to straddle a guide rail for said door, a bearing block supported between said guide flanges for sliding movement towards and away from said guide rail, a wedge for fore ing said block in the direction of said guide angle, and means for locking said wedge in the desired adjusted positioln 10. A guide shoe for vertically slidable tire doors comprising a bracket member adapted to be secured to the side edge of the door and having spaced guide flanges adapt ed to straddle a guide rail for said door, and bearing block supported between said guide flanges for sliding movement towards and away from said guide rail, a wedge for forc ing said block in the direction of said guide angle, means for locking said block in the desired adjusted position, and means where by the securing means for said bearing block is adapted to be released by exposure to fire.

11. A guide shoe for vertically slidable lire doors comprising a bracket: member adapted to be secured to the side edge of the door and having spaced guide flanges adapted to straddle a guide rail for said door, and bearing block supported between said guide flanges for sliding movement towards and away from said guide rail, a wedge for forc ing said block in the direction of said guide angle, means for locking said block in the desired adjusted position, and means whereby the securing means for said bearing block is adapted to be released by exposure to fire, said wedge being combustible, whereby it is adapted to become disintegrated when ex posed to the action of fire.

12. A guide shoe for vertically slidable fire doors comprising a bracket member adapted to be secured to the side edge of the door and having spaced vertical guide flanges adapted to straddle a guide rail for said door, a bearing block disposed between said guide flanges with one edge in coopera tive relation to said guide rail, a bolt extending through said bearing block and said flanges for clamping said block between said flanges, said flanges being provided with horizontal slots adapted to slidably support said bolt, a nut on said bolt, a combustible washer between said nut and the flange adj acent thereto, a combustible wedge extending between said flanges in position to engage said bearing block to force the same in the direction of the guide rail, and an ad justing screw mounted on said guide shoe in position to move said wedge into engagement with said block.
