LOCK.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed January 13, 1920. Serial No. 351,209.

Io all 222 mm it may (7071 cam Be it known that 1. JABIEIS E. PrrrnLirs, a citizen of the United States, and a resident of the city of New York, borough of Manhattan. in the county and State of New York; have inventec. a new and useful Look. of which the following is a full, clear, and exact description.

This invention relates to looks, and particularly to what may be termed a burglarprooi lock. and has "for an object to pro vide a construction which may be applied to any kind of a door, or in fact any kind oi: a device and at the sa. e time present a construction which will resist opening and being tampered with.

nothcr object or the invention is to provine lock rhich is especially des gned to successfully resist the action of rying instrument. as for instance jimmy. the lock including not only a bolt which may be projected and retracted at will, but a brace co-acting with the bolt tor resisting the pr in implement. I

r1 further object oi the invention is to provide a lock of a simple strong construction using a retractile bolt and one or more auxiliary catches which will resist any spreading of the door and jamb.

in the accompanying drawings:

Figure 1 is a rear elevation of the lock and brace embodying the invention, the same being shown applied to a door and jamb.

Fig. 2 is a sectional view through Fig. 1 on line 2-2.

Fig. 3 is airagmentary edge view of the upper part. of the bracing bar shown in Fig. 1.

Fig. i is a view of the look similar to that shown in Fig. 1. but with the front plate removed and part of the keeper shown in section. I

Fig. 5 is a sectional view through Fig. at approximately on line 55.

Fig. 6 is a transverse sectional view through Fig. d approximately on line (3-6.

Fig. 7 is aview similar to Fig. ti: except the parts are shown in retracted position.

Fig. 8 is a view similar to Fig. 7, but showing the roll back finishing the unlocking operation.

Fig. 9 is a fragmentary view similar to Fig. 1, but showing a pair of locking catches embodying certain features of the invention.

Fig. 1.0 is an edge view oi the bolt shown in Fig. at.

Referring to the accompanying drawings by nume ale 1 indicates a door of any desired kind and 2 a door jamb, door 1 carrying a lock 3 which is secured in place in any desired manner, as for instance by screws 4C. The jamb 2 carries a keeper 5 held in place by any suitable means, as for instance screws 6, said keeper being provided with an opening 8 for accommodating a bolt 9 and an opening 10 for accommodating the shank 11 of the catch 12, screwed or otherwise rigidly secured to the lock 3. The shank 11 is provided with a read 18 which overlaps the keeper 5 and positively prevents any appreciable spreading of the door and jamb. The keeper 5 is substantially L-shaped and arranged so that the body 14: acts as an ordinary keeper while an upstanding flange 15 is presented which will resist the entrance of prying tool, as for instance a jimmy.

Associated with the lock 3 and keeper 5 and coacting with the bolt 8 is a bracing bar 16, which at the lower end is provided with a hook 17 adapted to extend through an opening lS in the floor plate 19 as shown in the lower part of-Fig. 2. The upper part of the bar 16 is formed as shown in Fig. 8,

namely, with a notched out portion 20 accommodating the bolt 8, said notched out portion being inclosed partially by the projection 21 which fits in back of the bolt. A notch 22 is provided at the upper part of the bar 16 merging into the notch 20 and designed to accommodate a pin 23 rigidly secured to the keeper 5, said pin being formed with a head 24:. A second pin 25 having a head 26 is provided on the keeper 5 below the bolt 8 overlapping the bar 16 a short distance beneath the projection 21. This arrangement oi headed pins overlapping the upper end of bar 16 positively locks the bar against displacement, or against any removal except in the proper manner.

The lock 3 is formed with a casing 27 which may be cast, or made in any desired manner. A plurality of guiding projections or blocks 28 29 and 30 are provided for guiding the bolt 8 in its back and forth movement. The posts 29 and 30 and the enlargements 31 and projections or pins 33 which center the covering plate 34 when casing 27. This covering plate is provided with an arc-shaped tender or guard 35 arranged immediately above a substantially inverted U-shaped opening 36 (Fig. 1) said opening accommodating the pin or knob 3? adapted to be worked from theinterior of the door for actuating the locking mechanism. The bolt 8 is provided with a depression or cutout portion 38 for accommodating what may be termed a locking tumbler 39 which is pivotally mounted at 40 and is normally held depressed by spring il. The locking tumbler 39 is provided with notches 42 and 43 which accommodates at different times the stop 44. extending upwardly from the bottom of casing 27, said stop, if desired, being integral with said casing, positioned to positively prevent any reciprocation of the bolt 8 when the locking pawl is interlocked therewith. When the parts are in the position shown in Fig. 7 the bolt is positively locked in a retracted position and when in the position shown in Fig. 4: the bolt is positively locked in a projected position. The locking pawl 39 is provided with a bent over end 45 which is adapted to be engaged by the lever or roll back 46 rigidly secured to the shaft 47. Shaft 4;? fits into a bearing member 48 (Fig. 5) which is rotatably mounted in the covering plate 34 so that there may be a free turning action of the shaft and yet the shaft held in proper position. The outer or free end of the shaft is retained by bolts 49 which also act as locking means for holding barrel 50 in place. The shaft 47 is pinned or otherwise rigidly secured to the rotatable tumbler carrying tube 51 so as to rotate therewith when a proper key is used for raising the tumblers.

he look or locking mechanism 52 may be,

I if desired, of the cylinder type, a special type, or in fact any desired type which has a rotatable member and tumblers for looking the rotatable member against movement when the key is removed. This rotatable member, as just stated, is rigidly secured to the shaft 47 so that when the key is inserted and the rotatable member is actuated the shaft 47 will be rotated and the roll back 46 will be operated properly for either moving the lock to the position shown in Fig. 4 or to the position shown in Fig. 7. It will be noted from Fig. 5 that the bolt 8 is cut away at 53 for preventing a free movement of the roll back 46 so that it will first engage the projection 45 on the locking tumbler 39 and force said projection int the notch 54 in bolt 8, and then shift the bolt either to an openor closed position as the case may be. It will, of course, be understood that the bolt 32 all carry upstanding placed in position on 8 at notch 54 is suiiiciently thick for engaging the roll back 46 as it moves in either direction. It will be noted from Fig. 1 that in addition to member ll actingas a positive lock for preventing shifting of the bolt 8 the knob or pin 37 when arranged in either of the depressions 36 or 36 will also act as a lock for preventing shitting or the bolt. From the interior face of the door the looking bolt may be easily shifted by grasping the pin 37 and shifting the same from one notch 36 to the next notch 36", or in the other direction. To shift the bolt 8 from the outside of the door it will be necessary to insert a key and rotate the same to the desired extent.

In Fig. 9 will be seen a slightly modified form of the invention in which instead of having a single locking catch 12 two catches are provided, namely catch 12 anda similar catch 12 along the lower edge of the lock 3. Catch '12 is constructed identical with catch 12 and merely adds an additional reinforcement for preventing the separation of the keeper from the lock in case a prying instrument is being used. It will be noted that the lock 3 may be used so oarately, with one or both oi the catches 12 or 12 and it desired with the locking bar 16.

In applying the lock the plate 19 is arranged as shown in Figs. 1 and 2 and then the keeper 5 together with lock 3 mounted as shown in Figs. 1 and 2 and held in place by screws or other desired means; In order to mount the barrel 50 in proper place a round hole 55 is bored of the proper size to receive this barrel, after which a slot 56 is formed so as to receive the web 57 of the barrel 50. It will be noted that the barrel 50 and associate parts are held in position only by the nuts 49, but are prevented from rotation by the radiating web 57 fitting into the slot or notch 56.
