  • Publication number: 20160023372
    Abstract: A mortising tool or mortiser including a handle having a first longitudinal axis and a head having a second longitudinal axis. The mortiser includes an interchangeable scorer holder that has a first side and a second side. A first scorer is fixedly attached to the first side, and a second scorer different from the first scorer is fixedly attached to the second side. The interchangeable scorer holder is positionable in a first orientation substantially within a chamber to expose the first scorer and positionable in a second orientation substantially within the chamber to expose the second scorer. A guide is received by the mortiser and orients one of the first scorer and the second scorer at a desired distance from a face of a door. The guide is positionable in two orientations to orient one of the scorers at either a first or second distance from the face of the door.

  • Patent number: 5676408
    Abstract: A pocket door latch assembly has a housing with a latch arm pivotally mounted therewithin. The latch arm has a latch nose at one end and an inverted generally V-shaped slot adjacent its other end, and the arm is pivotable between a first position wherein it is entirely within the housing and a second position wherein the latch nose extends outwardly of the housing. An actuator has a portion slidable within the slot between a first position adjacent the one end of the arm and a second position spaced from the one end to pivot the latch arm between its first and second positions. The actuating means is manipulable outwardly of the housing to slide the slidable portion of the actuating means within the slot between its first and second positions, thereby pivoting the latch arm between its positions.

  • Patent number: 5463795
    Abstract: A hinge includes a first hinge leaf with two axially spaced knuckles and a second hinge leaf having a knuckle extending between and axially aligned with the knuckles of the first hinge leaf. The knuckles of the two hinge leaves have bores extending therethrough and that of the second leaf has a counterbore at each end thereof. Seated in the bore at each end of the second leaf knuckle is a bearing assembly including a collar portion seated in the counterbore. The bushing has an axial bore extending therethrough and a counterbore at its outer end. A metallic thrust bearing has a generally axially extending body portion disposed in the counterbore of the bushing, and a peripheral collar at the outer end overlies the outer end of the bushing and provides a thrust bearing surface for the adjacent knuckle of the first hinge leaf. In one embodiment, the bushing bore has channels to allow flow of electroplating solution if the hinge is electroplated after assembly.

  • Patent number: 5193308
    Abstract: A snap-in hinge assembly for mounting doors on door frames comprises a hinge with one of its leaves providing a plurality of spaced recesses, and a hinge leaf receiving receptacle mounted in a recess. The receptacle includes a reinforcing member having mounting portions secured to the frame or door and a seat portion defining a channel of a width dimensioned to receive the length of the hinge leaf. The seat portion has latch receiving recesses therein cooperatively positioned relative to the spaced recesses in the hinge leaf and a plurality of latch elements are disposed in the latch receiving recesses. Biasing elements bias the latch elements outwardly of the latch receiving recesses into the channel and they seat in the hinge leaf recesses when the hinge leaf is inserted thereinto. Thus, the door with one hinge leaf secured thereinto may be mounted on the door frame by inserting and sliding the hinge leaves into the channels of the receptacles to engage the latch elements in their recesses.
