LATCH.
SPECIFICATION forming part of Letters Patent No. 389,390, dated September 11, 1888.
Application filed August 16, 1887. Serial No. 247,087.
T0 all whom it may concern:
Be it known that I, ELMER E. KNoWLEs, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvementsin Latches, and I do hereby declare the follow-ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to mortise latches of the class which are inserted in the door by rstboringthemortise withabit5anditconsists in a certain combination and arrangement of parts, which will be hereinafter more fully described.
The object of my invention is to simplify the construction of such latches and render the same more durable and effective, and to cheapen the cost of the same.
In the accompanying drawings I haveillustrated one form in which I have contemplated applying my invention, and I have fully disclosed the same in the following specification and claim.
In the drawings, Figure l is a top view of the latch. Fig. 2 is a side view of the same. Fig. 3 is a similar view with the cap-plate of thclatch removed. Fig. 4- is a longitudinal section of the latch,showing the operative positions ofthe parts. Fig. 5 is atop view ofthe latch having the cap-plate bolt and spring rcrnoved. Fig. 6 is a similar view of the body of the latch having a modified construction. Fig. 7 is a view of the latch-bolt. Fig. 8 represents the tumbler or spindle-barrel.
The body of the latch is composed of two parts, A and A,the part A being the cap-plate or cover. The part A is provided with two recesses, c and c', the recess a containing the spring I),which presses against the partition d and keeps the bolt in its forward position. The part A is also provided with the opening a2 for the reception of the spindlebarrel C and with the boss or raised portion E, which is formed with smooth parallel edges lengthwise of the latch.
Thelatch-bolt consists of aflat piece of metal, and is provided with the usual beveled head fitting in an opening in the face-plate, which is constructed so as to offer a flat bearing sur- (No model.)
face at bto one end of the spring D. The opposite end of the bolt is provided with two projections or flanges, b b', for engaging the boss E of the body of the latch, said boss thereby forming a guide for the rear end of the bolt, preventing any lateral movement. This bolt B may be cast all in one piece; but I prefer to make the main portion of a flat piece of metal and attach the head to the same.
rlhe projections or flanges b b are in this case made by bending the side of the flat metal body-piece to form the same.
The spindle-barrel is formed, in the usual way of a cylindrical piece of metal having a central polygonal aperture for the reception of the spindle or shaft of the knob, and also with the ears or projections c c. These projections or ears engage the forward ends of the projections or flanges b b of the bolt,and give longitudinal motion to the bolt when the spindlebarrel is rotated by its shaft. The forward corners of the boss E are so arranged that when the spindle-barrel is rotated the projections c e form astop for the ears c c of the barrel and prevent the bolt 4from being drawn backward beyond a certain point. It also prevents a complete revolution of the spindlebarrel in either direction. In Fig. 6 I have shown, instead of the boss, two projections, E' E', which serve as guides for the bolt, and also as stops for the barrel,in much the same manner as above described. This boss or the projections may be cast with the part A or attached in any preferred way.
The cap-plate A is provided at one end with the projections e', which engage the boss E, thereby holding the cap-plate in position, and the two parts A and A are held in close engagement by means of a single screw, F. If preferred, the projections c may be made to serve as the stop for the bolt by making the projections b b of the bolt so that they will touch the projections e of the cap-plate when the bolt is in its retracted position.
Vith my construction a very durable and effective latch can be made very cheaply, as the parts are simple; hence easily made and combined. By means of the boss on the part A and projections b bof the bolt B, I obtain a guide for the rear end of the bolt, and also a stop for the same and for the spindle-barrel,
IOO
whereby the strain,after the bolt isin its most plane,engaging the projections of the bolt, the retracted position, is upon the boss and the projections of the bolt, the gnide,and the tumbarrel, instead of upon the bolt or its connecbier all lying in thesame plane,`u bstantially tions. as described. 5 What l claim, and desire to secure by Letters In testimony whereof I affix my signature in i 5 Patent, is presence of two witnesses. The combination, with a. latch-body pro ELMER E. KNOWLES. vided with a bolt-guide, of a bolt provided Witnesses: f with. projections engaging the guide and a FRANK A. HOLLENBECK,
