UNITED STATES WILLIAM KIRN, OF SOLOMON, KANSAS.
. nooR-sAsH LATCH.
Application led April 9,
To all whom it 712m/ concern:
Be it known that I, WILLIAM Kinn, a citizen of the United States,y and resident ot Solomon, county of Dickinson, State of Kansas, have invented a certain new and useful Improvement in Door-Sash Latches, .of which the following is a completespeciication. c L
This invention relates to locks for sliding doors and more especially a lock of this characterwhich does not employ springs or other relatively delicate or light parts which readily break or get out of order whenexposed to the weather and subjectedto rough usage. 1
One object is to produce a ,lock which. peculiarly appropriate for use in securing` the sliding doors ,of freight and otherrailroad cars'y'and warehouses where a simple, I
sturdy and eiiicient.` latch is desirable.
A further object is to producer` a lock ot` the character described which is strong,- durable, efficient and inexpensive, and in order" that it may be fully understood, reference is to be had to the accompanying drawing,
in whichz f i v y Figure 1 is a face view of a lock embodying the invention as it will appear when in use with abarn or other door, where it is desirable to .provide unlocking means acces`v sible from the interior as well as the exterior of `the building;
Figure 2 is a section on the lineII-LII of Figure 1;
Figure 3 is a face view of alock embodying the invention as it willappearjwhen in use for locking a freight cardoor or the like; Figure 4 is a section on the line IV-IV of Figure 3; il
y Figure 5 isa side elevation of a modified form of the latch of the lock.; and
Figure 6 is a perspective view of amoditiedV form of keeper Jr'orcthe fulcruming of the latch.. i i c j' In the said drawing, where like reference characters identify corresponding parts in all of the figures, lpindicates a building wall adjacent a door opening, and 2 a sliding door for such opening. Securedvertically to the l wall of the building Aadjacent the door opening is an abutment or stiffening jbar 3, to which is secured by means of .bolts 4 ata suitable height Vfrom the ground, a keeper plate 5 formed with a right-angle shaped keeper, 6 terminating in an inclined face 7 for guiding aflatch hereinafter referred to.
192s. serial No'. 630,850.
`The catch .6 projects inwardly beyondv theV edgeof the door jamb opposite the door 'opening and is adapted to overlap the edge of the door 2 when the latter is in its closed position. On Aits inner face the catch 6 is formed with a locking lng 8 providing a y and one portion 11 intermediate the ends of the bar is bent into contact with'the end 12 to form a resilient hinge and then is bent to L-form as at 13 to provide an operating handle, although it may be further bent as at 14, in dotted lines Figure 5. to provide a second rectangular portion, both constructions, however, operating the same.
The portions 11 and 12 which are in contact with each other are retained against a face plate 15 of metal to .decrease the vfrictional resistance of the parts, byV means of a bearing` member 16 bolted to the door and formed with a recess 17 for the reception of said portions 11 and 12 of the latch. In this connection it will be noted thatthe plate 15 n is bent back on itself'as at 15a, to fill the vmember 16 will be resisted by the resilience of the latch bar, as its pivotal action will be aroundtwo points which are off-center or eccentric with respect to each other, and such pivotal movement will tend to subjectthe resilient bar to a twisting strain. In this connection, it yis* desirable to pointv out that the latch portion 10and the handle 13 are bent outwardly away from the door to provide for* the necessary .limited pivoting action of the ylatch inward over the lug 8 preliminary to' snapping into the recess 9 and engaging .the rearV end of the lug to maintain the Ydoor in latched position.
In order to provide means whereby the lock may be `operated 'from the inside of a building, the inner Jface of the door, in line with the handle 13is recessed'` as at 18 and is formed with an opening 19 for sliding engagement with a rod 2() terminating at its outer end in ani eye 21 ted on the handle 13. The inner end of the rod may be provided `recess 9 for thereception of the latch, as
with a Yhead u22 for 'the 4convenience of the movement, as' will be, readily understood.
In order to provide Vmeans for engagement by a padlock (not illustrated) or the like, whereby the door mayrbedsecu'red;` against opening movement, a hasp 23 is Secured tothe door at such a point that it will underlie the lug 8 of the keeper 6, and formed in the catch 6 is a perforation24,
the parts lbeing so located with respect toL each other that the`r keeper lof a' padlock `may be readily engaged` through the-hasp 23 and the opening 2,4 andfretain the door against operation..-
The lock, as illustrated in Figures 3 and 4 is adapted more particularly for use on railroad car doors and is similar in all respects to the lock above-described, except that it willbe noted-'the plate t is provided with a right-angle shaped extension ,25
g adapted to brace the abutment bar The end of extension 25v is securely fastened-to the side of thel car by one or. more bolts 2,6. It will also, be evident that with a freight car doorfit. is unnecessary to make provision for the operation of the latch from the interior ofthe car, asia shipment is usually loaded and then the car sealed until it attains its destination. l
The following mechanism is provided for sealing the latch when utilized with a car door: Projecting from the-keeper 6 and lying. paralleltothe carare a pairof ears 27. and 28, the'former being the` lowermost and having an oblong opening 2,9 and the latter Vbeing formed with a circular opening 3.0; Engaged through openings 2 9 and 30. is an invertedY J-shaped stop member 31, the longleg of, the stop being upset asat 32 to, permit passage: through opening 29 but to. prevent withdrawal through the opening 30 of. theear 26, while the short leg` isl adapted, to pass downwardly through the recess 9 inward of they latch 103 and fill said recess and thus. prevent.V unlatching movement of the latch (see Figure 4g). The lower end of theshort leg of the stop memberprojects belOw the keeper 6 and is v formed witha slQt 33 for engagement with a car vseal 34 of any suitable, character, which -will encircle the long.- leg of the-stop, as illustrated. It will be;J apparent from the construction describedA thatit will be vimpossible tooperate lthe latchY tounfasten the, door as long as the seal 3.4 remains unbroken; i L* As above mentioned, the purpose of the metal strip 15 secured to; ay door onj which it is desirable to employ a lock vembodying the invention7 is to provide a suitable bearing surface for the pivoting action of the latch. It has been found, however, that man?,7 doors are not equipped with a suitable metalstrip andin order to provide a suitable bacl'iing and' at the same time a keeper for the latch members, it has been found desirable to produce the following device: In Figure 6, a metal plate35 is bent to form a channel portion-36 to receive the parts 11 and 12 of the latch, and'said plate Vis provided with a tongue portion 37 projecting' from one edge of the channel.k The tongue portion 37, after the latch members have been engagedV in position, will be hammered or otherwise forced downward until its exteriorf face isiush with t-herear face of the plate 35, as shown by the dotted line, Figure 6, the free edge of said tongue being received in a recess ,384 for its accommodation. It will be evident that with a device of this character the latch members will'be simultaneously retained in position anjduprovided with a suitable metallicv backing.
It will be evident that when a door equipped with a-lock, embodying the, inven-l tion isslid shut, that its latch 1,0, through contact with the inclined face 7' of :the
keeper; 6, will be rocked inwardly against the resistance of its parts 11 and 12 vuntil it has ridden over the lug 8 when it will instantly snap into the recess 9 and be engaged with the rear end of the-lug, and securely holdfthe door in closed position.
It is believed that further recapitulation of the operation of the=lock is unnecessary. From. the abovedescription it will be 4apparent that I have produced' ardevce embodying the features yof advantage setwforth as desirable in the statement of the objects of the invention, and which may be modified in minor particulars. without departing from the principleA of. construction and mode of operation involved. i
I claim:
-k "1. lock structure ycomprising keeper,
.a lath ofloop. form adapted 01* engagement with said keeper; the latch being in the form of a continuousjbar having two portions of its length adjacent and parallel, and a bearing member :encircling said overlapped ellds, said parallel,y portions being adapted toY rotate. on their own axes.;l
2. A lock structurefcomprising a keeper, a` latch, of loop form adapted fon engagement with. said keeper; the latch being in the form of,- a continuous barhaving one end overlapped with fan intermediate portion, and a' bearing mem-bari encircling Said Overlappedv portlets .which are adapted' to, rotateron, theircwn axes.v-
3. A lock. structure: i a. keeper,
r engagea. latch. of loopform adapted ment with said keeper; said loop being pivotally secured at a point intermediate its length, and terminating at one end in an operating handle, the other end of said latch 5 being pivoted eccentric to said intermediate portion.
