uw i me sgi-e s f y toen keeper,

To all whom t may concern.' Be it'known that I, RICHARD WoooFINE, a citizen of the United States, residi'nglat Mimet ilthe County of shbshon andere@ of `ldalio, i haveminvented new and Im royements in Locks, of 4which thffflolloyvinglis a Specification.

A`This"inventionn relates to improvements in theI construction of'locks, and ali/object ,of thefinvention is to"constructl a lock, p rimarily intended ,for employment upon warehouses orthe like, which, while of asimple and" comparatively'cheap construction, includesnsubstantially heavy bolts so arranged as Ato be simultaneously moved in a longitudinal direction toward ior awaylfrom the and whereinv both the` boltsfniist have` their ends entirely withdrawnfromu'the keeper before the door can beopen'e'd."

Another object ofthe invention lis to construct a lock including double b oltshaving teeth or rack bars thereon and whi'chare engaged by a pinion lhav'ing a nbarrel',thereon for the receptionof a key whereby both of the bolts Will be simultaneously moyed in opposite directions toward or away .from the keeper, and also whereby both of the bolts cannot be readily brought into unlocking position except by persons familiar with the working of the device.

With the above and other objects in view,y the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawings: Figure lv is a front ele vation illustrating the application of a lock and keeper constructed in accordance with the present invention. Fig. 2 is a sectional view approximately on the line 2-2 of Fig. 1, Fig. 3 is a sectional view approximately on the line 3 3 of Fig. 2. Figfil is a perspective view of the bolt or tumbler for the keeper casing, and Fig. 5 is a similar view of the bolt or tumbler for the lock casing.

ln the drawing the stationary member is indicated by the numeral 22 and the movable member by the numeral 23. The keeper 24 is secured upon the stationary member, while the lock casing 2,5 is secured upon the movable member.

Both the lock and keeper are of a substantially similar formation, the Side plates of which may be substantially rectangular, but one of each of said plates is formed with Specication of Letters Patent. z ma. il. v.

an approximately semi-circular vflange 26, andfeach ofmaidiplat'es is formed with a peripherally'integralblock 27 spaced from the flange'tprpvide' a semi-cylindrical passage 2S 'etw'eejntlieblockand thelflangeQ. v,This pa a e 2,8 'c' mm'unicatfes with suitable openf; snin the fae plats, and arranged withinL ea'ehtif tliel'passages is )a semi-circular boltnie 'i ber Each ofthe bolt members 30 is', formed upon its opposite sidesor faces rib's'llf-fwhich' are received in suitable grooves upon the Arespective flanges", 26 4andblocks 'i271' The grooves4 32 afe arranged'longitudinally upon Ithe flange 2G and't'he'rblockffor the major portion ofthe le'figthjof saidfflange and blo'ck, and the 1of'the Vgrooves provide abutments1 fr'fthewribsf to prevent the bolts 30 beijfg entirely moved out ofthe passages 28.

si'h"34"wliich communicates with the passage28 and which is adapted to serve as a pocket for a toothed wheel 35 which meshes with the teeth 33 of the lock bolt 29. The toothed wheel 35 is provided with a stem 36 that has a transverse kerf 37 and which extends through the removable side plate of the lock and which is adapted to receive a suitable key whereby the bolt of the lock may be actuated to contact with and revolve the bolt of the keeper so that one of the ends of the keeper bolt will be received in the groove of the lock casing and one of the ends of the lock bolt will be .received in the keeper casing. The bolt members, it is to be understood, are adapted when in unlocking position to be arranged flush with the face plates 29 of the lock/and of the keeper, and it is only when the said bolts are brought to this position that the movable element can be disengaged from the stationary member as will` it is thought. be perfectly understood.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without .further detailed description.

Having thus described the invention, what ,l claim is:

' l. In combination with a lock casing and a keeper easing, of a bolt in each of the casings, means for actuating the bolt in the lock casing to bring the ends of the bolt flush with the face plate of the lock casing or to cause the bolt to enter the keeper casing to contact with the bolt therein to bring one end of the last mentioned bolt out of the keeper casing and to within the lock casing.

2. The combination with a look casing and a keeper casing, of a bolt arranged in each of the casings, each of said casings having their bolt openings arranged to aline When the face plate of the lock casing is brought against the face plate of the keeper casing, the bolt in the lock casing being formed With teethI` a toothed Wheel in the said casing engaging with the teeth, a kerfed stem connected with the toothed Wheel and projecting through the lock casing whereby W'hen turned to revolve the toothed Wheel to bring the ends of the bolt flush with the face plate of the lock casing or to move the bolt to within the keeper casing to cause the same to Contact with the bolt in the said keeper i casing and to move one end thereof out of the keeper casing into the lock casing.

3. A lock casing and a keeper casing each having a semi-circular passage and the said passages adapted to aline when the lock easing and keeper casing are brought together, a semi-circular bolt in the passage of the lock casing and in the passage of the keeper casing, and means for actuating the bolt in the look casing to bring the ends thereof flush with the entrance to the passage or to project one of the ends thereof through the said passage to Within the passage in the keeper casing to cause the said bolt to contact with the bolt in the keeper casing and force one end of the last mentioned bolt through the passage of the keeper casing into the passage of the lock Casing.

4. A lock casing and a keeper casing each provided with a semi-circular passage which communicate when the casings are brought together. the opposite Walls of the passage being formed with central grooves, approximately semi-circular bolts one for the passage of the lock and. the other for the keeper casing. each of said bolts having its opposite edges ribbed to be received in the inentioned grooves of the passages, the ribs o-n one of the bolts being slotted to provide teeth, a toothed wheel in one of the casings engaging with the said teeth, and a stem upon the wheel projecting through the casing.

In testimony whereof I affix my signature in presence of two witnesses.
