Abstract: A door spacer adapted for mounting in the space between a sliding door and its top track to prevent vertical motion of the sliding door into the space adjacent its top track member, comprising a base member and first and second legs forming a triangle with an apex which extends vertically into the space between the sliding door and the top track. Means are provided to move the point of attachment of one leg to the base longitudinally along the base to adjust the vertical height of the apex above the base of the door spacer.

Abstract: A Christmas tree stand consisting of a water bowl with a down-turned rim and channel-shaped legs with slots complementary to the lip of the rim and abutments below the slots complementary to an abutment on the rim. A link extends from the end of the leg nearest the center of the bowl downwardly to the bottom of the bowl where it is secured against upward movement by a bracket attached to the bottom of the bowl, the bracket including an up-turned end having a sharp point to penetrate and immobilize the bottom of the tree trunk. The top end of each link and leg are threaded to receive a tree trunk engaging screw. As the trunk engaging screws are tightened to secure the tree trunk in an upright position at the center of the bowl, an outward force is applied to the top end of each link and the inner end of the corresponding leg, making the entire structure rigid.
