LOCK AND LATCH COMBINED.
ESPECIFIGATION forming part of Letters Patent No. 660,061, dated October 16, 1900. Application filed November 4,1899. Serial No. 735,829. (No model.)
To all whom, it may concern: ished portion of the bolt projects rearwardly Beitknownthatl, JOHNB.E.lVIAONAMARA, through the plate A In the center of the of the city and county of San Francisco, State bolt Gis provided an aperture having con- 55 of California, have invented a new and usevergent inclined sides 0 C and off the adja- 5 ful Lock and Latch Combined, of which the cent ends of said aperture is a slot C within following is a specification. which the bolt is formed into a wedge 0 .This invention relates to a combined lock Fis the lock-spindle,which is provided with and latchthat is to say, a door-fastening the knobs F F on opposite sides of the door 60 whose bolt is controlled by a key and can B. As shown in Fig. 1, this spindle passes 10 be worked by a knob from either side of the through the flanged plates G G screwed to door. the door B on opposite sides thereof, through The object of the invention is to provide a the openings B and A respectively provided door-fastening thatis simpler, less expensive, in the said door and in the tube A therein, and 6; more convenient and eifective, and of easier through the central aperture 0 of the bolt (1 application than either the common lock or aforesaid. It is loose and therefore longitulatch. dinally movable across the door B and rota- My improved lock and latch requires no table upon its own axis. The middle portion mortising, but only a small hole made in of it is cut away to forma pointed or angular 70 the edge of the door with an ordinary brace segment F, the sides of which are arranged and bit. to meet the inclined sides 0 O of the aper- Referenceis had to the drawings heretoanture G which are carried against them by nexed for a detailed description of the inventhe spring E. tiou. Running across the door B, between the 7:
In the said drawings, Figure 1 shows a horishanks of the knobs F F, Within the flanged zontal section of an ordinary hinged door proplates G G and through the caseAand bolt 0, vided with my combined lock and latch. Fig. is a double wedge H, the two points of which 2 is a front elevation, partly in section, of the are made to engage the two sides of the wedge construction shown in Fig. 1. Fig. 3 is a de- 0 hereinbefore referred to as being protailed view of the lock-bolt with the lock-spinvided on said bolt within the slot 0 thereof.

Fig. 5 is a deinto the cut-away portion of the lock-spindle tailed view in perspective of a double wedge F, bearing at opposite ends on the uncut round used in connection with the lock-bolt and lockportions of said spindle.

In the tube A is placed the bolt 0, the spindle if the latter is pushed or pulled,

Slots are probolt is pressed outward normally by means of vided in the tube A and door B at A A a spiral spring E, coiled around adiminished and B B to allow the wedge H to be moved 10o portion 0 of said bolt and bearing at one end longitudinally with the spindle F in either 50 against the shoulder (J thereof and at the direction. The e'li'ect of this longitudinal other end on a small perforated plate A runmovement either way of the double wedge ning across the tube A. The said diminwhen taking place is to force back the single turning the same in eithcrdirecti on.
- e oei 'wedge C of the spring-pressed bolt 0 and consequently'to retract said bolt andipermit the door to be opened, as will be readily understood.
Besides being adapted to withdraw the bolt. C'through the wedges H and O by a sliding movement across the door in the manner above indicated, the lock-spindle F is also capable of exerting a direct action. on said bolt, as may have been observed, owing to the connection of its segment F with theinclined sides 0 O? of the bolt-aperture 0 Such action will result from the rotary movement of the spindle F on its axis in eitlierdirection, as then either edge of the segment F will press against one of the inclined sides 0 or C of the bolt-aperture andpush the bolt backagainst its spring. E, thereby leav ing the door free to open again. The double wedge H remains at rest during therotatiotn of the spindle eitherway, as abovenote'd.
It will now be seen=that myinven-tion provides four different ways of retracting the fastening bolt of a door-to wit, by either" pushing or pulling. on the'l'ook rspindleor by The movement in each instance-is positive and cannot fail to bring. aboutt'he result sought to be accomplished.
In order to keep the bolt G retractedwhem ever it is desired to leave the door open, I provide a pin J, which passesthrough anextension of the plate Gand thedoor B and can be inserted in a. hole C", drilled for'it across the bolt C. Other means'of'kemoing the bolt withdrawn may, however, be adopted, if preferred, as this is not an'ess-cntial or important feature of my invention.
To look thedoo'r and prevent it't'ro'm being opened'from either side except by a key, I place at the bottom or inner end of theJtube- A; a rotary stop K opposite the inner e-n'dof the bolt 0 therein. As will be seen by reference toFig. 2, the stop K is made witha cavity or hole K in one side-,.which the inner end of the bolt 0 will enter'whe'nthe sam'eis facing it; but-the remainder of said step is solid, so that when the ca vi ty'or hole is out of line with the bolt the latter cannot be withdrawn. ing through a slotrA in the tube A, guides and limits the movement of the-stop'K. Thisstop is given a quarter-turn at the inner end It could be given ahalf-turn either Way and operate to lock and unlock the bolt in the samemanner I of the bolt to lock or unlock it.-
A small pin or screw K pass 1 if the perforation were carried through. It be reached from either side of the door by a suitable key-such, for example, as is shown in Fig. 6.
Having now described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
1. A combined lock and latch comprising an apertured bolt formed with an inside wedge, a non-rotating double wedge passed through the aperture in said bolt and engaging the sides of said first-named wedge, and a rotary spindle also passed through said aperture and longitudinally slidable through the bolt with said double wedge, substantially as set forth. 2. latch comprising a-bolt provided with awed ge, a n-o-n"-rot;atablewed ge engaging said first-mentionedwedge, and a rotary spindle longit'u'dinally slidable with said non-rotatable wedge, substantially as described.
3. A latch comprising-a bolt having an inclined face; arotat'able spindlehaving a seg- .ment -s'haped portion adapted upon the rotation of the spindle, to engage said inclined face and operate the bolt, and a non-rotat'a blewedge adaptedupon a longitudinal moveinent-of the spindle, to engage an inclined face on the belt and operate the same, substantiallyas described.
4. A combined look and. latch comprising a tube inserted in a suitable hole or recess in the edge of a door, a spring-pressed bolt therein, said bolt having-a central aperture and slot with a wedge in said slot, a non-rota-ting long itudinally slidable double wedge passi'ng'throughsaid aperture and slot and Lthrough corresponding openings in said tube and door'and engagingthe sides of said firstnamedwedge; a spindle also-passing through tlieapertured bolt,- tube, and door, and congtrollingt'h'e longitudinal movements of said doublewedge, sa-idspindle having its middle portion for-med intoa segment the edges of g'ture; and suitable kn'obsor handles whereby said spindlecan either be pushed or pulled or turned in either direction, substantially as set forth.
