BOLT LOCK Joseph R. Grifi'ith,,Lynwood,-Calif.
Application May-5, 1955, Serial-No. 506,289
8 Claims. (CL'29-2- 148) Generally speaking, the present invention relates to the latch and lock arts and, more particularly, pertains to a bolt lock attachable to a door, cooper-able with 'a padlock to lock said door to a jamb, and selectively unlockable from one side of said door and relockable from the other side of said door independently of said padlock.
It is an object of the present invention to provide a bolt lock adapted to cooperate with a padlock to elfectively lock a door from 'a first side thereof and serve as a manually openable latch from a second side thereof.
It is also my object to provide a bolt lock, of the sort described in the preceding object, which is of an especially simple, rugge efiective and novel construction, especially suited for use on heavy exterior doors.
Other and allied objects of the present invention will occur to those skilled in the art after a careful study of the present specification, the accompanying illustrations, and the appended claims.
To facilitate understanding, reference will be made to the hereinbslow-described drawings, in which:
Fig. l is a perspective view of a preferred embodiment of the bolt lock of the present invention, locked with a padlock and with bolt means in extended, locked position; the padlock and certain invisible elements are indicated by dashed lines;
Fig. 2 is a perspective view of the device of Fig. 1 after it has had the bolt means unlocked from theinside (second side)the parts shown solidly have moved from the posi 'ons they occupied in Fig. -1, all stationary parts being indicated by dashed lines;
Fig. 3 is a perspective view of the device of Fig. 1 after it has been unlocked, by removing the padlock, from the outside (first side), only parts which have been moved from the positions of Fig. 1 being shown solidly;
Pig. 4 shows a section through the device of Fig. 1, taken along the plane, and in the direction, indicated by the line and arrows 44 of Fig. 2; a second position of the handle and control means is shown in dashed lines;
Fig. 5 is an elevation of the device of Fig. 1 as seen, installed in a door,from the second side thereof; and
Fig. 6 shows a section, from the position shown in Fig. 4, of an embodiment of the present invention in which the control means is of different construction from that shown in Figs. 1-4; parts similar to those of the device of Figs. 1-4 are numbered similarly, but with primed numerals.
In the bolt lock illustrated in Figs. thebody means is a semi-cylindrical shell with closed ends, as indicated at 1. The open diametral plane of the body means-is in use against the surface of the first side (left side in the figures) of a door A in which an aperture B has been provided as shown in Fig. 4. The body means has mounting flanges 2 which connect it to the door through the use of rivets or bolts (not shown) of a type non-removable from the first side and cooperable with mounting holes 3. On a portion 4 of the lower mounting flange this portion .4 maybe mounted separately 'on -thedor if 2,78 1,215 Patented Feb. 12, 195.7
-desiredstaple 5 is held. Apadlock'C is linked through it in Figs. 1 and 2 to lock ha'sp 6 '(whose aperture fits over the staple) on the staple. Ha'sp 6 passes through a slot 7 in the semicylindrical shell 1. Through an aperture 3 in the first end 1a of the shell 1, passes longitudinally slideable bolt 9, which is rotatable about its lo'ngitudinal axis. To lock the door the bolt end engages a bolt receptacle on a door jamb, which structures are well-known in the art and hence are deemed not to require illustration. Projecting from bolt 9 are pin 10, handle 11 which extends throughsaperture B to the second side of door A, and flange 12. A collar portion 6b of hasp 6 is slideable along the bolt 9 and defines'an aperture whose ends are eugageable by pin 10. The aperture B in the door is virtually rectangular: its length should allow the travel of handle -11 from the position of Fig. l to the position of Fig. 2 or Fig. 3. As shown in Fig. 4, on the left side the wood of the door is further cut away below aperture B to allow the flange 12 to travel freely between the two positions of Fig. 1 and Fig. 2.
Support piece 13, a portion of the body means, has a hole 13a through which the bolt is movable. A compression pring 14 is held, between piece 13 and the flange 1-2, around the bolt, biasing the flange and bolt away from piece 13 in the outward direction of bolt movement. In Figs. 2 and 3 the spring is compressed, the bolt being unlocked; in Fig. 1 the spring has pushed the bolt out to the extended locked position, the :movement between Fig. 2 and Fig. 1 being in said outward direction.
By comparing Fig. l with Fig. '3 it may be seen that to unlock the bolt from the first side one removes the padlock C, removes hasp '6 from staple 5, and by moving the hasp along slot '7 withdraws the bolt (its inward direction of movement), compressing spring 14 in the process; the collar portion 6b of the hasp engages the pin 19 to move the bolt.
A second support piece 15 of the body means has a bearing hole through which pin 16 passes rotatably, being held in place by a cotter pin and a washer. Pin 16 is a part of the catch 17, the detent region of whose cam surface is indicated at 18. The weight of the catch biases it against flange 12; when the bolt is withdrmvn the dctent region engages the flange to maintain the bolt in an unlocked position. The bolt may be relocked from the first side by raising (in aperture 20) external graspable control 19-allowing the flange to leave the detent region, so that the spring forces the bolt in its outward direction. From the second side, the bolt being unlocked (by handle 11) one can raise the catch to relock the bolt by swinging handle 11 up against internal control 21 as show'n in dashed lines at 11a, 17a, 19a and 21a in Fig. 4. Or, internal control 21 may be raised manually.
In Fig. 6 an embodiment is shown in which internal control means 21 is somewhat longer than that used in the form of the other Figs. so as to permit ease of man ual operation of the catch from the second side of the door; the catch is biased against the flange by a leaf spring 22 attached to the body shall 1'; and the external control 19' has a stud portion 23 which covers aperture 20 to prevent the entry of injurious materials into the bolt lock and which allows effective manual operation of control 19. in this form of the bolt lock-although it is shown, like the preceding form, in a horizontal position-the device may be used with the bolt lying in a non-horizontal or effectively vertical position: the catch does not depend on gravity to bias it against the flange. The outward direction of the bolt movement couldb'e either a wamor, preferably, downward (as infuse' on a dutch doerf), M k r The embodiment of the -present invention specifically 3 described, illustrated and claimed herein is exemplary only, and is not intended to limit the scope of the present invention, which is intended to be interpreted in the light of the prior art-and the appended claimsonly, with due considerationlfor the doctrine of equivalents.
