CAR-DOOR FASTENER AND SEAL Application filed February 27,1939. Serial No. 431,780.

This invention relates broadly to car door fasteners, and more particularly. to a com bined fastener and seal for the doors of railway cars, the seal being of that type designed to indicate whether or not the door has been opened or tampered with following its application to the door.

The primary object of the invention is to provide a novel and ellicient car door fastener embodying a seal of the character mentioned which shall at all times truly indicate to an inspector or others the condition of the car to which it is applied; that is to say, plainly indicate that the door has been, or has not been, tampered with, as the case may be.

A. further object is to provide a car-door fastener embodying a plate or disk which, in the act of unfastening to permit opening of the door, becomes mutilated or deformed to the extent that it clearly presents visual indication of the fact.

With these and other objects in view, the invention resides in the features of construc-v tion, arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a portion of a car illustrating my invention applied thereto; 1

Figure 6 is an enlargedsection on line 66, Fig. 2, with pants shown broken away to illustrate features of the mechanism;

Figure 7 is a section on line 7-7, Fig. 6, showing the latch members occupying their closed, .or door-fastening, positions;

Figure "8 is a similar view showing said members shifted to door-releasing positions; and

Figure 9 is a detail section on line 99, F i g. .3.

Referring to said drawings, 1 designates a base plate adapted to be ri 'idly mounted upon the outer face of a car door 2 adjacent to the forward lateral edge of the latter. Rigidly mounted on said 1 is a casing 8, shown herein as cylindrical in form, iaving a fixed outer face portion 4. Secured within opposite sides of said casing so as to form therebetween a vertically extending open space 5 are segment-like blocks 6 which have formed in the confronting faces thereof recesses 7 in the upper portions of which are vertically slidable the opposite ends of a crossbar 8. Said crossbar constitutes a vertically shiftable member of a latch by means of which an arm 9 is normally held in seated overlying relation to the face l of the casing 3. Said arm has pivoted or hinge-like connection with the base 1 adjacent to the upper end of the latter, having its upperend rigidly carried by a crossbar 10 having trunnion-like mounted for rotary movement in suitable hearings or mountings 11 carried by said base.

The vertically shiftable latch member, or bar, 8 rests upon the upper ends of a pair of compression springs 12 which have their H lower ends supported by the upwardly facing shoulders 13 formed on the blocks 6 by the provision of the recesses 7 hereinbefore referred to. A companion latch member 14 of l1oolrfo1m is rigidly carried by, or formed integral with, the arm 9, being directed inwardly from the rear face of said arm, as shown. In the normal lowered position of said arm, said latch member 14 projects through an opening 15 provided therefor in the face 4: of the casiin and has the hook end thereof engaged with the upper edge of the bar 8, is clearly shown in Figs. 6 and 7.

A function of the hinged arm 9 is to coopcrate with a laterally slidable bar 16 to secure 9 the car door 2 against movement from its closed position. Said bar 16, which i as an outwardly directed hook-like front end 17, is designed to underlie said arm 9 at a point above the casing 3 when said arm occupies its seated operative position and to be retained by said arm against shifting movement from its said underlying position, the hook-end 17 thereof being engaged with the said arm at the side opposite that toward which said her ends is shiftable in withdrawing movement thereof. Said bar is mounted for longitudinal sliding movements in a suitable keeper plate 18 which is rigidly mounted on the side of the car body 19 adjacent to the door 2, as shown.

A second function of arm 6 is normally to retain in position a clestructible or defo mable member 20 which is insertable and removable with respect to a countersunl: seat 21 provided therefor in the face of the casing Said deformable member, preferably provided in the form of a heavy paper or rardboard disk, is held lirmly upon its seat 21 by a rearwardly directed boss "22 formed on the rear face of said arm 9 in encircling relation to a circular sight opening 23 provided in the latter. or covering 2 for said opening 23 is prei ably provided, as shown, for preventing access to the disk through said opening.

Journaled for rotary movements in the opposite blocks 6 and crossing the intermediate open space 5 is a shaft which has one end hereof projecting outwardly through the casing wall. Fixed on said projecting end of said shaft at a right angle thereto is an operating lever 26 which is normally maintained inoperative for rotating the shaft by a movement-preventing plate 27 which is mounted upon an adjacent portion of the base 1. Said plate 2?, herein show. as pr vided with a vertical slot 28 through which project the headed ends of belts or screws fixed in the base 1, is vertically shiftable to and from a positionwherein its lower edge portion underlies the upper end, or nose portion, 30 of the operating lever 26, as shown in Figs. 2 and 3. A knob or other suitable prejecting member 31 carried by said shiftahle plate 27 provides means whereby the latter maybe manually grasped for effecting the required shifting movements thereof.

Directed radially through and lined in the shaft midway between the blocks (3 is a pin 32 which, in rotary movements of said shaft effected by raising and lowering the operating lever 26, is designed to have its pointed end penetrate or puncture and to elfect mutilation of the disk 20, a vertically disposed incision 3?; of more or less irregular or raggec form, and, consequently, of read f noticeable appearance, being produced in said disk by said pin as rotation of the l tter is continued following the puncturing of said disk.

The opposite end of the pin 32 projects in a rearward direction from the shaft 25 and is adapted, as said shaft is rotated by elevating of the lever 26, aforesaid, to engage and carry downwa d therewith a forwardly directed lug 34: formed on the lower end of a metal tongue 35 which is fixed to and depends from the rear face of the latch bar 8. This movement, through the intermediacy of said tongue 35, serves to retract said latclrbar A transparent glass face in a downward direction and against the tension of its supporting springs 12, el'l'ecting disengagement of said bar from its companion member 14. ith said lever 26 held in its elevated position, the arm 9 is released and may freely be swung outwardly and upwardly, or toward the elevated position shown in Figs. ii: and In such position of said arm, not only may the door securing bar 16 be freely shifted to a position permitting opening of the car door, but a so free access is ali'orded for the removal of the mutilated disk and for the introduction of a new disk, 't being understood that the operating lever is dropped to its normal. position prior to the insertion of the new disk.

To render futile attempts of persons to introduce substitute or duplicate disks for genuine disks which have been mutilated, the genuine disks may have printed thereon data or information (not herein shown) which is not readily accessible to, or not readily applicable by, unauthorized persons.

In practice, wit i the arm 9 occupying elevated position, a disk 20 is introduced in proper position upon the seat 21, and the door securing bar 16 is shifted to its extended position wherein it overlies the base 1, whereupon said arm is lowered and forced inward to its seated position with respect to the casing 3. In approaching said position the curved nose portion 36 of the hook end of the latch member A carried by said arm 9 engages and rides over a corresponding nose curvature 37 formed on the upper edge portion of the vertically movable latch member, or bar, 8 and acts to thrust the lat-- ter downward against the tension of the springs 12. lVhen said hook-end of the member 1% has passed over the bar 8, said sprin s 12 return said bar to its normal elevated position wherein it interlocks with said men'iber i l, as shown in Figs. (5 and T. In its said seated position, the arm 9 not only retains the disk Ll) in place, but also secures the door-securing bar against shifting movement to the position in which the car door is released. Finally, the plate 27 is shifted to its lowered position wherein it partially underlies the nose of the operating lever 26 for preventing elevation of the latte In this connection it is to be understood that the plate 27 may be omitted without in any way affecting the function of any other parts of the structure, its purpose being merely to deter tampering with said lever by rendering the elevation of the latter to disk-puncturing position slightly more dillicult, in that the use of both hands and consequent stopping alongside the car is re quired to elfect elevation.

To effect opening of the car, the plate 27, vhen such is employed, must be elevated to permit initiation of elevating movement of the operating lever 26. Such movement of fit said lever actuates' rotary traveling movement of the shaft-carriedpin 32wherein the pointed end of the latter is carried into puncturing and incision-producing relation to the rigidly held disk 20, thus to presentpositive visual proof of the fact of said lever movement when the disk is ,inspected through the sight opening 23. Additionally, and at the same time, said lever movement causes the opposite end of said pin 32, acting through the intermediacy of the tongue 35, to retract the latch bar 8 from interlocking relation to the latch member 14, whereupon the arm 9. becomes released and may be swung to its elevated position, releasing the door-securing bar 16, which latter is then ihkeely shiftable within its ke 21' 18 to its withdrawn position with respect to the door.

It will be noted that, whereas the casing and the therewith associated mechanism are herein shown, described and claimed as mounted on the car door, and the door-se- .curin bar and its lree Jer are described and claimed as mounted on the car body, this arrangement may be reversed. Therefore, the appended claims are to be understood as applying to either of the two arrangements noted.
