JULIUS GROSSIVIANN, OF VVE STCHES'JER, NEW YORK.
LOCK.
To all whom it may concern Be it known that I, JULiUs GRossMANN, a citizen of the United States,"and resident of Westchester, borough of the Bronx, city, county, and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.
My invention relates to locks and has for its object to provide a lock which is reliable in action and not easily tampered with by unauthorized persons and which is simple in construction and readily operated under intended conditions.
My improvement further contemplates the provision of a lock which will afford a protection against the door on which it is used being accidentally left unlocked, and
which will further practically eliminate the possibility of the leaving behind of the key necessary to operate the said lock.
Other objects of my invention will appear from the description hereinafter and the features of novelty will be pointed out in the appended claims.
- Reference is to be had to, accompanying drawings which illustrateone specific example of my'idea and in which Figurel is a face -view of my improved lock and" ooperating parts in position on the door and door frame; Fig. 2 is a plan view thereof showing the door and frame in section; Fig. 3 is a horizontal section on the line 33 of Fig. 1; Fig. 4 is an inside face view of the lock with the cover-plate removed; Fig. 5 is a section on the line 5-5 of Fig. 1. and Fig. 6 is a detail face View of one of the parts of said lock. 7
In the drawings 10 represents a door and 11 the door jamb, said door being provided with a suitable opening 12 for the accommodation of a tumbler barrel or cylinder 13 which may be of any suitable construction and which may contain tumbler mechanism of any known type. The said cylinder 13 is secured in operative position in any convenient way as for instance by means of screws 14 cooperating with a plate 15 and lugs 16, the latter being secured to or forming part of the cylinder or barrel 13. The lock further comprises the usual casing 17 secured in proper position on the inside of the door in any suitable manner as by screws 18 and having the usual removable cover plate 19 n best in Fig. 3. The one end portion o of the said casing is extended so as to Specification of Letters Patent. I ym m A1110, 9 1 914 Application near/ra 20, 1912.. Serial No. 768,718.
project over the free edge of the door for a considerable distance from the inside, the said portion 20-being countersunk so as to be flush with the edge surface of said door and being suitably secured thereto. With casing 17 is provided with a suitable aperture for the accommodation of a latch 21 rigidly carried by rods 22 slidably mounted in a plate'23 which is preferably loosely positioned between grooved stationary lugs 24 forming part of or secured tothe casing 17. The said plate 23 also forms a bearing for one end of springs 25 which surround the rods 22 and also bear against the latch 21 and serve to maintain and return the same to its operativeor shot position and at the same time maintain said plate against said lugs 24 as will be apparent from an inspection of Fig. 4. The rods 22 are further provided with projections 26 which in the assembled condition of the lockare engaged by preferably T- shaped plates 27 and 28 located respectively on opposite sides of said rods 22-as shown best in Fig. 3. The plate 27 is secured to a member 29 rotatably mounted in the casing 17 and held against axial movement in one direction by means of a flange 30, the said member 29 having an angular portion 31 and a screw-threaded end 32 the purpose of which will be'described more fully later on. The plate 28 forms part of a sleeve 33 rotatablymounted in the cover-plate 19 and providedwith an axial opening 34 of angular cross-section through which proadapted to fit into a similarly formed aperture in a bolt section 38, a nut 39 cooperating with the screw-threaded end 32 to secure said bolt-section 33 in position on the portion 32. The said section 38 is pivotally connected at 40 with another section 41 preferably L-shaped as shown in Figs. 1 and 6, said sections 38 and 41 together forming a bolt 41 andbeingcut away so as to overlap at their adjacent ends and form shoulders,
movement relatively thereto in a downward direction by means of the squared end '43 abutting against the shoulder 42 of the section 38. The section 41 is also preferably provided with a knob or handle 44 for 1113. nipulating the same relatively to the section 38, both sections when in their extended or operative condition resting in a bracket shown in Figs. 1', 2, 3 and 5.
forming part of or secured to the casing- 17 and located adjacent to the overlapping ends or pivot of the sections 38 and41, said bracket 45 preferably being ofsuch'width as to extend completely over said overlapping ends.
A keeper 46, has a plate 47 projecting for a considerable distance over the door jamb l1 from'the inside and countersunk therein so as tobe flush with said jamb, said plate 47 being secured in position on the amb' 11 in any suitable .manner as by screws 48, this construction servingto secure the keeper firmly in position-and preventing ready dislocation thereof. This keeper 46 is provided with an aperture 49 for the accommodation of the latch 21 and is furtherformed with an upwardly open recess 50 into which the bolt section 41 is adapted to fit when the door 10 is looked as The said keeper 46 is provided with a lug 51, the
. purpose of which will appear more fully farther on in the description, and is further provided with alining apertures 52. into which a pin 53 is adapted to'be inserted to prevent an actuation of the b olt 41 as will be more fully brought out hereinafter, the latch 21 being formed with an aperture 21, arranged to be brought into registry with a similar opening 17 in the casing for the' accommodation, of said pin 53 under certain conditions. The said pin 53 is preferably secured tothe casing 17 by means ofa suitable flexible connection as a chain 54 in v desired. In addition to this, one of the rods 22 may be extended beyond the one end of the casing 17 and connected with a handle I 22 for manually retracting the latch 21, the
connection between said rod 22 and handle- 22= being preferably,such as to make said handle detachable.
When the door 10 is locked the parts of the lock are in theposition shown best in Fig. 3 .in which condition the latch 21 is positioned in the opening 49 and the bolt 41 is located in the recess 50. A double lock is thus secured so that even if an effort is successfully exerted from the outside to force the latch 21 backward out of the opening .49 the bolt 41 would still eflectively secure the door against opening. It will be' noted that the pivot 40 is in close proximity to the. free edge .of the door so that any instrument which might be in- 11 for the purpose of swinging the section '41 out of the recess 50 would engage said section in close proximity to said pivot 40. A considerable leverage or force would thus be requiredto swing the said section 41 on its pivot. 40 with v the result 'that an effort to thus actuate the bolt to open the door would in most cases be unsuccessful. -H0wever,'to absolutely prevent such unauthorized actuation ofsaid bolt section 41. from the outside, the .pin 53 is inserted into the openings 52 'asshown in Figs. -2 and 5 in which position the said pin 53 bridges the recess 50 andextends above. said bolt and prevents any movement thereof.
It will of course be understood that it is impossible to swing the bolt sections 38' and insertedinto the barrel or cylinder 13 as the usual tumbler mechanism therein will pre- 41: as a unit unless a proper key is first venta rotation of the menrber 29,"ste1'n 35'" and collar 37 when the properkey' is. not in the lock and thus prevent an actuation of the bolt 41 as a whole. By providing the bracket 45 in the neighborhood of, the pivot 40 the saidbolt 41 is firmly secured against fractureat its weakest point if an attempt to jimmy or otherwise force the door should be made. That is the force exerted on said bolt 41 in-such an attempt would be taken up by the bracket 45 and the keeper 4G and would prevent breakage of the bolt The door may, therefore, be effectively locked during the nightor such other times as unauthorized entrance is to be prevented and the occupants of the particular room orro oms are therein. Assuming that person actuating the lock as described, the
the bolt section 41 hasbeen released by the said section will immediately drop back into I alinement with the section 38 into the position shown in Fig. 6 it being preferably (iverbalanced slightly to insure this result." In other words the normal position of the menace bolt 41% is as shown in solid lines in Fig. 6, with the sections 38 and 41 in al-incnient. 1f the person leavesthe said room and swings the door 10 toward its close position, the said bolt 41*" will bebrought into engagement with the lug 51 on the keeper 46. This leg is of such dimensions as to prevent the latch 21 from snapping into the recess 50 and thus prematurely locking the door and preventing a reopenin thereof if the necessary keyshcaid accidentally have been left behind.
In order to properly lock the door itis' necessary to insert the proper key into' the barrel 13 and rotate the connected collar 3%,
to allow for any sagging of the door which may take place. This stop 17' also revents the bolt 41 from being forced completely back and thus protects thetumbler mechanism against injury which might result from such movement. Should it be desired to use only the latch- 21 withoutthebolt 41*, i
the section 41 may simply be swung-ion the pivot 40 to the dotted position shown'ia 6 and the hook 57 brought into engagement with the knob 44 to maintain saidsectiou 41 in this position. In this condition the latch 21 is free to snap into the opening 49 and may be opened by the proper key in the usual manner as the position of the bolt section 41 will not interfere therewith. If the entire lock is to be rendered inoperativeso that the door may. beclosed without being locked the latch 21 is also simply drawn back by the handle 22*? until the openings 17 and 21 are in registry and the pin 53 then inserted therein. In this condition of the parts, the door may be closed Without being locked as will be readily apparent.
My improvement it will be seen provides an efi'ectlve lock which is substantially incapable of being operated excepting in the intended manner and which is practically incapable of being dislocated or pried from the door from the outside, this latter being also true of the keeper plate. In addition to this, my improvedlock also firmly locks the door in its closed position and prevents the same from being jim'mied or otherwise forced open. The opening 49 for the latch 21 is prefer-ably made somewhat larger in a vertical direction than the said latch so as to allow for any sagging or dropping of the I door, such change in the positions of the door thus having no efiect on the operativene'ss of said latch.
"Various changes in the specific form shown and described may be made Within the scope of the vclaims without departing from the spirit of my invention.
