I "MICHAEL MULLINS, OF NEW YORK, N. Y.
. LATCH.
' SPECIFICATION' forming part of Letters Patent No. 244,921, dated July 26, 1881.
nppncnnonied Aprile, 1881. (Modeif To all whom t'tmay concern:
Beit known that I, MicHAEL J. MULLINs, of the city and county of New York, in the State of New York, have invented certain new and useful Improvements in Mortise- Locks or Knob-Latches, of which the following is a specification. v
The objects o f my invention are to providea novel construction and arrangement of devices for transmitting motion from the spindle boss or hub to the latch-bolt, and to provide means for securely attaching the roses. These objects are accomplish ed by the construction and arrangement of parts illustrated-in the accompanying drawings, in which- Figure 1 represents a section of aportion of a door and a side view ofra mortise-latoh embodying my invention, and inserted therein, the side plate of the case being removed; and Fig. 2 represents a transverse section upon the irregular dotted line no x, Fig. l.
Similar letters of reference designate ,corresponding parts in both the iigures.
A designates the mortise in the door, in which the latch is fitted; and B designates the case of the latch, which has one side plate, B', re movable, as is common.
U designates the spindle boss or hub, which its in holes in the two side plates ot' the case; and D D designate the two roses, which are secured to opposite sides of the door. As clearly seen in Fig. 2, the wood upon the sides ot' the mortise A is quite thin, and if the roses D were secured by ordinary wood-screws in the, usual way, the screws would not have a good hold in the wood and would be apt to work loose. In order to obviate this difficulty, I form upon the inner side of the back plate of the case aprojection or hub, B2, which is of circun lar or semicircular form, and is ot a thickness nearly equal to the internal width of the case. The hub or projection B2is not acomplete circle, but is open on one side, and the spindle hub or boss ts loosely within it. In the projection or hub B2 are holes a, which correspond in position with the holes in the roses D, and are screw-threaded to receive screws b, by which the roses are secured. The screws of one rose pass directly into the case upon whichY the projection or hub is cast, while the screws ofthe other rose pass loosely through the re movable side plate, B', and into the projection or hub B2. If rivets are employed in place of screws, the holes in the projection or hub should be coincident with the holes in the roses, and then the rivets may be inserted directly through the door and lockcase and through both roses.v
In lieu of being made continuous from one end to the other, the projection or hub might be sectional-that is, composed of isolated hubs or sections arranged in a circular form.
It will be seen the form of the projection or hub B2 precludes making the spindle boss or hub() in the usual way, with toes upon opposite sides, and I will now describe the mechanism of thelatch.
E designates the ordinary'latch-bolt, and F designates a lever-piece pivoted to the bolt at c and fulcrumed at d. The head of the lever F has two opposite ears or lugs, c c,in the former of which one end of the spring G is fixed, and the latter of which is acted upon by a toe, f, upon the spindle boss or hub C. The boss or hub G has also a long toe or arm, g, which engages with a lug or projection, h, upon the bolt E. When the spindle-boss or hub C is turned in one direction the toe or arm g, acting on the projection h, draws in the bolt E, the spring Gbeing deflected by the connection of the lever F with the bolt E, and when turned in the opposite direction the toe f acts upon thelug or ear e and draws the bolt in by moving the lever F. It will also be observed that when the holt is out, as in Fig. l, the lug orear e bears upon the projection or hub B2 at t', and thereby forms a stop to preventundue outward movement of the bolt E.
In lien ot' the roses being separately secured by screws secured into the projection or hub B2 from opposite sides, longer screws might be inserted loosely through one rose, the lockcase, and the door, and screwed into the opposite rose; but in this case, as well as where rivets are used, no projection or hub B2 would be necessary. In any case, however, the screws or rivets, if inserted directly thrgugh the lockcase, would interfere with the working of the ordinary spindle boss or hub and lever, and therefore the bolt-actuatingdevices previously described are necessary.
What I claim as my invention, and desire to secure by Letters Patent, is-
IOO
1. In n. mortise lock or latch, the combinetion, with the rotating spindle boss or hub C, tted in the sides of the lock or latch casing and constructed with the dependin gtoes f and g, of the bolt or lntch E, having the lug inthe nprightleverF, connected atits lower end with the bolt or latch, the upper end of said lever being connected at one side with the spring G, and operated at the other side by the toes f and g of the rotating spindle boss or hub, substantielly as described.
2. A nlortise lock or latch casing having on the interior of one of its sides a laterally-projectinghnb, B2, provided with transverse epee tures c a for receiving the screws or rivets b b, I 5 which ettachthe rosesin piaee,in 'combination with the rotating spindle boss or hub C, hevng the depending toes fand g, and the upright lever F, connected with the bolt or latch E, thc upper portion of the said lever being connected zo at one side with a. spring and operated at the other side by the toes on the rotating spindle boss or hub, substantially as described.
