Specificationforn-iing part ofLettersPatent No. 194,000g1dated August 7, 1877; application'filed'.
. lJuly12, 1877. 1 v i f To all whom it may concern:
Be itknown that I, JAMEs SARGENT, oi"
Rochester, in the county of Monroe and State of New York have invented certain new and useful Improvements in` Door-Bolts, of which thefollowing is a specification;
This invention relates to an improved fastening device for doors and other `like purposes, in which the bolt is projected and re; tracted: by means of a pinioned key-spindle, operating upon aseriesof ratchet-teeth formed in a recess.` in the-bolt, the bolt being arranged to reciprocate ina tubular barrel or suitable guide, with apertures onopposite sides forming lbearings for the spindle-key.V
The inventionhas for its object to provide for the locking of the bolt either in aY projected or retracted4 position, so that it cannot be shifted; by` any pressureapplied directly to theside or end of said bolt; to provide for securing thehandle to the 'spindle-key,and, y incidentally, for the convenient attachment of the tubular barrel or guide to the Vplate or fastening attachment, by means of which the device is secured in the door.
To these ends theinvention consists,flrst, in providing the bolt with a ratchet or series of teeth formed in a recess therein, either one or both of the terminal teeth of said ratchet or series of teeth beingcut away in such man,- ner as to cause one of the teeth of the pinioned spindle to bear-against the next succeeding tooth of the ratchet or seriesof teeth when the bolt is fully projected, said terminal teeth being Varranged at such an angle as to prevent thebolt from being retracted by any direct pressure upon the side or end ci' the same; and, second, in constructing the spindle or key with pinion-teethv extending from one extremity to the other, wherebya pinioned spindle isformed for engaging with the rack of the bolt for projecting and retracting it; and a keyed bearing is likewise formed for the handle, which is thereby secured to the spindle, so as to prevent said handle from turning thereon, all as hereinafter more fully l described and claimed. 4
In the drawings, Figure l represents an elevation of a portion of a door with my improved bolt attached thereto. Fig. 2 represents an elevation of a portion of the edge of a door,

FiguS represents Aa detached vievvl of the spindle-key and theescutcheon. Fig. 9` represents an elevation of the bolt and spindle-key, showing the bolt in a retracted position. Fig. l() represents: a detached elevation and longitudinalsection of theiescutcheon and spindle. v j
rThe letter A represents,v a ,tubular barrel, guide, or support, constructed of metal or other suitable material; and B a bo1t,con structed with cylindrical ends, adapted to resaid tubular barrel, guide, or support. i c
The bolt is provided with a recess, C, formed, preferably,at therear end of the same, alsOme other por tion, said recess being provided withta ratchet The letter D represents a pinioned.` spindle or key, by means of which the. bolt is pro- 'jected andretracted.
The recess G is of a depth equal to the diameter of the spindle or key D, in order to enable the spindle to be journaled in the apertures b b, formed directly in the sides of the tubular barrel or guide A, in such position as to properly gear with the ratchet or series-of teeth in the bolt.
One or both of the terminal teeth of the ratchet are cut 'away on one side, or constructed of such relative size or shape to the other teeth,rand to the teeth of' the pinion key or spindle, as to throw the said terminal teeth out ofV bearing against the pinion formed on the spindle or key when said bolt is fully retracted, and cause the next succeeding tooth of the ratchet to bear the teeth ofthe pinioned Qkey or spindle, which lies at such an angle in relation to the said tooth of the bolt as to hold said bolt either in its projected or retracted position, asthe case 4 may be, and lock or dog it when projected directly against one of the tubular barrel, guide,
i collar, I, by means against any strain or pressure applied to the side or end of that portion of the bolt which projects from the case.
The letter E represents a spring secured to the bolt, which bears against the interior of or support A, and aids -in regulating, by frictional contact, the movement of the bolt therein.
The tubular barrel, guide, or support A is constructed with an external male screw, a, at its forward end, which engages in a similar female screw-thread, e, in the plate E', which is `provided with countersunk apertures e' for the insertion of screws, by means of which the tubular barrel or support is secured in a mortise in the edge of thedoor.
The spindle or key D is constructed in the form of a pinion., the teeth of which extend from end to end, and the knob or handle G is formed with a recesscorresponding to the shape of the teeth, and is forced upon said spindle, the teeth of the same serving to key it securely thereon, and prevent it' from becoming loose, without the aid of other fastening devices. The teeth of said spindle, just inside ot the escutcheon, are recessed, as shown at h, and in said recesses is secured a of which the spindle is coniined in the handle, and held in its bearingswhen the device is secured to a door.
Thedevice is secured in the edge of a door, in a suitable mortise or recess formed therein, by means of the screws inserted through the plate F, a proper recess being formed in the frame of the door over which is secureda keeper, K, Fig. 3. The spindle is inserted through'an aperture in the face of the door Aformed directly opposite the position of the apertures b when the tubular barrel, guide, or support is in position, and is held in its bearings by means of the escutcheon, which is secured to the door in the usual manner.
The operation of my invention will be readily understood in connection with the above description. The bolt is projected and retracted by simply turning the pinioned spindle in the proper direction. When fully projected the terminal teeth of the ratchet, which are cut away, are thrown out of bearing with the teeth of the spindle, bringing the succeeding tooth against the end of one of the teeth of the spindle, be in such position in relation to said tooth as to lock and hold the bolt against any strain or pressure brought directly upon the same, so as to prevent it from being retracted except through the medium of the spindle.
In order to provide for greater security against opening from the outside, the tubular barrel may be provided with but one aperture b for the pinioned spindle, thus making it impossible to project or elevate the bolt from the outside by means of pliers or any other similar instrument.
What I claim, and desire to secure by Letters Patent, is
1'. A lock-bolt provided with a ratchet or series of teeth, c, in combination with a pinion,
' spindle, or key, D, one or `both of the terminal teeth of said ratchet or series of teeth being cut away, so as to throw said terminal teeth out of bearing against the teeth of the spindle, and cause the succeeding tooth of the ratchet to bear against one of the spindleteeth, substantially as described, whereby the bolt is held in a locked or dogged position against any pressure or strain applied directly thereto through means other than the spindle, as set forth.
2. In combination with the bolt B, having y a rack arranged within a suitable casing, the spindle or key D, formed with pinion-teeth extending from end to end of the same, for receiving the knob or handle -G attached thereto, and to operate the bolt, substantially as described.
In testimony that I claim the foregoing I have hereunto setmy hand in the presence of the subscribing witnesses.
JAMES SARGENT.
