LOCK.
' Application medium 7, 1915.
To all whom it may concern:
Be it known that I, GUs'rov SoHULz, a citizen of the United States, residing at J ansen, in the county of Jefferson and State of Nebraska, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had to the accompanying drawings.
My present invention relates to new and usefulimprovements in looks .and has particular reference to those of thetype which are essentially adapted for use in connec tion with the doors of barns, sheds and similar out buildings.
Primarily, it is the object of the invention to provide a lock of this character which will, in case the door is violently pushed or struck from the inside, yield to the impact, permitting thedoor toopen, instead ofre-' sisting until the lock is broken.
' Ai'nore specific object of'the lnvention 1s toprovide a lock in which the latch plate carried by the door amb or post is pivotally secured at one terminal and is, therefore, adapted at times, for' swinging movement, butis normally held against such movement and in fixed position to serve as a catch forthe spring pressed bolt of the'door car-' ried portion of the look, by -means of a wooden rod or hinge pin, whlch member 1s adapted to yield in'case an abnormal blow is struck the door from'the inside of the building, as when a horse in a barn kicks the door.- I
The above, and other incidental objects of a similar nature, which will be herein-- after more specifically treated are aocomplished byv such means as are illustrated n the accompanying drawings, described 1n the followingspecification, and then moreparticularly pointed out in the claims which are appended hereto and'form part of this application.
With reference to the drawings, wherein there has been illustrated the preferredembodimentof' this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a front elevationshowing the lock applied to a door, which member together with the adjacent wall of the building, .is 1 fragmentarily shown; Fig. 2 is a vertical longitudinal section taken through the lock casing; Fig.
Specification of Letters Patent. Patentgd D 2 1 1915 Serial No. 32,788.
3 is a section on the line 3-3, of Fig. 1;and Flg. 4 is a section on the line 4.4,of Fig. 1..
As best disclosed in Fig. 1 of the accompanying drawings, the lock of the present invention includes generally, a casing A, wherein is slidably mounted, a spring pressed locking bolt B; and a latch plate C which is adapted to form a catch for the locking bolt. The casing A is secured in the door D in a manner which will be next explained and the latch plate is secured to the door jamb E. i
The lock casing A consists in a preferably rectangular frame 10, and a pair of face plates 11 and 12 which are secured against opposite sides thereof. The frame 10 is seated in an opening 13 formed in thedoor, while the face plates are disposed to form closures for this opening and are seated with their edge portions disposed inshallow recesses 14, in a mannerbestdisclosed in Fig.
' 4. Bolts, indicated at 15 are passed through the corners of the face plates and through the intervening portion of the door, forsecuring the plates and the frame in proper The plate 11 is preferably fixedwith the plate 12, if an additional fastening 1 means is desired.
In the outer vertical end wall of the fram 10, is formed an opening 18 through which the outer end of the lock bolt B is projected. This lock bolt 13 is cut-away at its outer end,
providing the beveled face 19 as in the ordinary lock bolt and is provided at the inner end of this beveled terminal with a transverse stop shoulder 20 which, by engagement with the end wall of the frame 10, is adapted to limit the outward movement of the locking bolt. As a means for normally holding the bolt in projected position, I employ a helical spring 21 which is interposed between the inner end of the lock bolt and the inner end openings 27 formed in' the plates 11- and 12,
wall ofthe frame 10, being wound a-tits one end about a; stud 22formed. on the lockbolt and at its other end about a stud 23 carried by the inner face of the innerend wall of the frame 10.
Upon the upper face of the lock bolt ar a plurality of rack teeth 24 which are en' gagea-ble :by the-teeth of a. mutilated pinion 25. This member 25 is keyed upon or cast integrally-with an axle 26,theter1nina'ls of-' which are journaled in horizontally alined as in Fig. 4. The terminals of the axles project beyond the fixed plates and are provided with transverse bores or openings 28, where in may be secured the trunnions 29 formed on the terminals of the handles 30. A handle 30 is thus provided foreach side of the door. Obviously, as-will be seen upon reference to Fig. 3, either of the handles may beturned to retract the lock-bolt and disenga-ge-thi'smember from the latch plate-which will be next described. I
"Thelatch plate heretofore designated as a-n'-entirety, by the letter C, includes three sections 31, 32" and 33. The member 31 is substantially T-shapedand is arranged with itshead portion 3i in vertical position. In-
tegral sleeves or tubes indicated at 35 and d 'areformed at the ends of the stem portio'ns' 3'7'ofthe member 31 to receivethe pins- 1 3 38l and-39', which members also pass through tubes or-sleeves-40 and 41 formed on the terminalsof the members 32 and 33. The pin 38', which passes through the sleeve .41 is formed preferably of steel, while the pin 39 whichpasses through the sleeve 40 is preferably-formed from wood. The plates 32' and 3 3 areeach provid'ed' 'witha pairoflong-n tudinally extending' slots 42, through which lag; screws are passed and threaded intothe door jamb or post, for holdingthe plates-1n beyond the face ofthe door jamb and in the n so 1916f the lock boltwill ride over the outer. edge of'the member 34, until the bolt is,
path of the projectingterminal of the lock bolt, as in Fig. 4.
The actualfconstruction and arrangement offthe several parts of the invention, being thusldisclosed, it 'now remains to describe" briefly the manner in which the device is operated. Referring,therefore, to Fig. 4' it be seen that'when the door is swung inwardlyto closed position, the beveled face passed inwardly of thismember and has again'been projected by the spring 21 to engage-"against the inner face of the member 34. The door isthus locked against movement until one of the handles isturned to retract the locking bolt. In case the door is kicked from the inside by a horse or through any source subjected to an abnormal blow or impact, it is obvious that the lock embodied 'herein will not resist the blow to the extent that the lock will, itself, be broken, If. the
blow or impact is of sufficient force to break an ordinary lock, the wooden pin 39 will break, allowing the plate 34: to swing outwardly, thereby permitting, the door to open...
In reduction to practice, itha-sbeen found that the form ofthis invention illustrated;- in the accompanying drawings, and referredto in the above description as the preferred embodiment is the mostefficient and practi-' cal; yet realizing that the conditions concurrent with the adoption of this device-will necessarily vary, it is desirable to emphasize the fact that various minor ch'anges inthe details of'construction, proportion andar ra-ngement of parts maybe resortedto,"when required, without sacrificing any-of the a dvantages of this invention, as-defined by the appended claims.
' What is claimed is 1. The combination with alockh-aving a projectable lock bolt, of a latch plate,- sa'id latch plate including abasesection; a' section;
pivotally. attached thereto, an-d -amember normally maintaining the second mentioned section against movement, said second men"- tioned section being engageable by theloc-k: bolt, and being relatively inflexible, butofanatureto break, allowing the'pivoted'endto; '1'
swing outwardly and release the bolt inca ser the door to which the boltissecured i'sisu'b? jected to an abnormal force.-
' 2. A latch plate forlo'cks including a pairof plates fixed adj acent'the door-to; which 3 3 the lock is applied, a T shaped section -pivot-' ally attached to the fixed sections, thei T shaped section being engageable by the-bolt of the lock, and a member connecting-the T-shaped section and the fixed 'sections,
held against movement,said member being adapted to break under a force less thanthe; 7 force required to break the lock. V 3. A latch plate for locks'including two similar plate sections, each provided-'witlr elongated horizontally disposed slots, lag screws passing through the slotsfor securing theplate sections to a supportingstructure,
