Jamb door stops are seldom required for water-closet doors hung to wooden partitions, but when needed there is to be had a simple stop with a rubber tip that will answer all purposes. Where stops are required for doors hung to marble partitions the type shown in Fig. 131 may be used. This stop has a clamp device that is attached to the marble slab by bolts and it will be observed forms a combination stop and strike for the latch or bolt. [Illustration: FIG. 131] [Illustration: FIG. 132] Other water-closet specialties, which are not illustrated here but which are sometimes specified under hardware, are: Coat-and-hat hooks, cigar holders, cigar and paper holders combined, and toilet-paper holders. Each can be procured to secure to either wood or marble, as required. =92. Screen-Door Latches.=—There is a light latch manufactured, either rim or mortise, for use on screen doors. It consists of a knob latch similar to a mortise latch or cupboard turn, but in addition to a hub, as in the former, it is furnished with a spindle and a pair of knobs, or lever handles. Latches for screen doors are also constructed with “stop-work,” so that they cannot be operated from the outside except by the means of a key. This latter latch is generally of the mortise type, having escutcheons on both sides. =93. Elevator Latches.=—Locks or latches for use on doors of elevator shafts are usually operated by a key from the outside and by a flush lever handle from the inside. The latch illustrated in Fig. 132 consists of a pivoted arm with a hook at its end to engage with a strike on the jamb. This type of latch is the one generally employed. [Illustration: FIG. 133] =94. Secret Gate Latch.=—In Fig. 133 is shown a =secret gate latch=, which is used for office gates. Latches of this kind may be had in either the rim or the mortise type. They usually consist of a spring bolt that cannot be operated except by a concealed button or similar device. In the type of latch shown in the figure, the concealed button that controls the latch is located on the lower edge. The knob shown is fixed and does not operate the latch. =95. Ornamental Nails and Studs.=—Although the constructive necessity for =ornamental studs= and =nail heads= has disappeared under modern methods of wooden construction, they are still used for purposes of decoration, and a great variety may be had. Several stock designs are illustrated in Fig. 134. These nails and studs are made of various metals and in many finishes, having a projecting spur on the back that, when driven into the wood, firmly attaches the ornamental head in place. They contribute effectively to the decoration of important doors, especially extension doors of churches and public buildings.
