CARDOOR FASTENING.

To all whom it may concern:

lie it known that we. PAUL P. Panties and Pizucr M. llanmx, citizens of the United States. residing at Mile, in the county of l-iscataquis and State of Maine, have invented certain new" and useful Improvements in Car-Door Fastenings, of which the following is a specificatitm.

This invention rclatest'o certain new and useful ii'nprovements in car door fastenings.

The invention has 'mrticular reference to that class of seal fastenings or locks employed on sliding freight-car doors.

Reference will be had to the accompanyingdrau-ing forming a part of this specification and -w,he rein like nmnerals of referignated respectively by numerals and 6,

These walls are shaped to closely fit the carside 2 and the door step 3, as illustrated in Fig. 2., lVithin the casing 4 .is pivoted a latch 7,by means of a vertical pin 8 passing through the top and bottom walls 5 and (S ofthe casing, the pin being secured by its head and by a cotter pin 9 concealed within the casing.

The latch is normally pressed toward the car door and side by means of a spring 1-0, the free end thereof engaging thefront wall of the casing and the intermediate portion 10 bearing against and straddling the latch,

'the portions of the spring above and below the latchcoiling around the pivot pin 9.

Midway of its length, the latch is bent outwardly thereby providing a substantially right angular portion 11 which oftsets the pivoted and free ends 12 and -12 respectively of the latch so that the latch will straddle the door stop 3, said'stop beingslightly cut away as at 14. to accommodate the latch. The extreme free end of the latch, on the. side or edge adjacent the car, is provided with a lug or hook 15, which serves to secure the car doorclosed,

. The car doorl, is'e nipped with a strike- 3 corner of which is Specification of Letters Patent. Application filed October 5, 1909. Serial No. 521,127.

' ation of the latch,,and tl Patented Feb. 1, 1910.

rounded to present a beveled face 1" for the. purpose of engaging the rounded nose 1? of the latch to raise the latter upon closure of the door. The strike-plate 1G is provided with an aperture 18 for the reception of the hooked end of the latclr,v said hooked end also extending into a recess 19 formed in the car door.

llxtending outwardly from 'the' ortion 12 of the latch and substantially mi way at a point adjacent the in lermediate portion 10 is an integral arm 20; which projects through an openingQl in the front wall ofit-he casing, and extending outwardly from the centralportion of the front wall of the casing are a pair of cars 21, integral with'the said casing. Pivoted to the said ears ill by means of a pin 22 is a hasp 2&, said hasp being also pivotally connected midway of its. length and by meansof a pin 25'to the extreme freeend of the said latch arm 20. The free end of the hasp is provided with the usual slot 26 for the reception of the staple or other member 27 which is integral with the front wall of the casing 4. n

It will be noted that the latch and hasp swing in arcs of different radii, and inasmuch as the saidlatch and hasp are connected together by arm 20 for simultaneous movement and cooperation, it is necessary to compensate 'for such difference in movement, hence the pivoted end of the hasp is slotted as at 28 and it is through this slot; that the said pivot pin 22 passes.

To secure the hasp in its loc ring position, a. hook-shaped locking pin 30 is provided, the free-end of which passes through the eye of the staple member 27. The hooked .portion of the locking pin is provid d with apertures 31 through which the s al wire 32 passes to close the open end of said hooked portion. The opposite end of the lot-kingpin 30 passes through an opening 33 in the said strike-plate l5 and is provided with a ball 34; of greater diameter than that of the opening33, said ball being received in a socket 35 formed in the car door. By

means of this ball and socket mounting-for the locking pin, a free swiveling movement of the latter is permitted to facilitate its being properly and easily ins'erted'through the eye of the staple member 27.

It will be observed that ample space is provided within the casing for proper opercnsin adjacent the do l the pening -hasp, and such moveinent will be impossible then pull on the'hasp, which; latter movement will disengage the latch.

slightly therebeyond' to conceal the securing end of; the latch and the cooperating portion of the strike-plate. To revent access into the casing at this end: itis closed by an'end wall 36. e

The operation of the device is as. follows: Upon closing the door the rounded corner 16 of the strike-plate will engage the rounded nose 1? of the latch and elevate the latch. Vihen the door has been completely closed, I the hooked end 15 of the latch will enter the aperture 18 in the strike-plate due to the pressure of the sprin and-thereby secure the door closed. As T18 latch is lifted, the hasp 24: is' correspondingly lifted and when the latch returns to its locking position, the hasp also returns to itsp sition' against the casingas illustrated in Fig. 2. The locking pin 30 is then assed tliroiiglrthe eye ofthestaple mem er 27 and sealed, thereby securing the hasp against the casing and likewise the latch in looking engagement with the door. By thisconstruction it will be impossible for the latch 'to be disengaged from the door without movement of the without detection, ow'in to the sealed locking pin." To unlock/the .door, it is only necessary to rcmove t h'eflocking pin and to Having fully-described the invention, what is claimedas newand useful'and desired to be secured by Letters Patent, is': A
