Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed October 22, 1912. Serial No. 727,237.

To all whom it may concern:

Be it known that I, FRANK W. CHAFFEE,

a citizen of the United States, and a resident of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Car-Door Fasteners, of which the following is a specification.

The invention pertains more particularly to fastenings for the doors of freight cars, and it is applicable to cars having a single sliding door and also to cars having two sliding doors and ordinarily called automobile cars.

I present my invention herein as applied to the doors of an automobile carrying railway car, without however intending to con fine the invention in all its parts to any special character of freight car.

The object of the invention is to produce a very durable and highly efiicient means for locking the hasp commonly employed on freight cars in securing the doors thereof, and in carrying out my invention I provide a suitable casing containing a vertically slidable bolt and carrying a staple over which the hasp may be placed andwhich staple contains a vertical opening to receive the said bolt, said casing being of the speciafi construction hereinafter described claimed. The casing referred to will be secured to the door-stop when employed in connection with a car having a single sliding door and W111 be secured to the edge of one of the two doors when employed on auto mobile cars, and in the latter case said cas ing will not only be bolted to the door but' additionally secured and the door strength ened by a suitable bar secured thereto'and extendlng over and engaging the base por-' tion of the casing about the staple-thereon. The means for properly holding the hasp, which is employed in connection with my new locking devices, may be of any suitable construction, but .I recommend for this purpose the construction presented herein and described in Letters Patent of the United States No. 1,017,136, granted to me February 13, 1912.

The invention will be fully understood from the detailed description hereinafter presented, reference being hadtothe accompanying drawings, in which:

Figure 1 is a side elevation, on a reduced scale, of a portion of an automobile freight car having doors equipped with the fasten.

ing devices of my invention, the doors being shown in their closed pos1t1on; Fig. 2 is a detached face view 011 a larger scale, of the door fastening devices embodying my invention; Fig. 3 is a horizontal longitudinal section through the same and a portion of the car doors taken on the dotted line 3-3 of Fig. 2; Fig. 4 is a vertical transverse section through a portion of the same on the dotted line 44 of Fig. 3, and Fig. 5 is a vertical transverse section through a portion of the same on the dotted line 5-5 of Fig. 3.

In the drawings, 10 designates a portion of the side of a freight car, and 11, 12 denote two corresponding sliding doors mounted thereon, said car and said doors being of any suitable or of the well known general construction. I apply to one of the doors, say the door 11, the features constituting my invention, and to the door 12 I apply the means disclosed in my aforesaid Letters Patent dated February 18, 1912 for securing the hasp 13 thereto, said means, generally speaking, comprising a bar 14 secured to the door, a pin 15 extending through an eye in the shank end of the hasp and a plate 16 secured to the bar 14 and engaging the outer bent end of the pin 15 and therewith serving to confine the hasp 13 and permit the same to have the usual movements required in applying it to or removing it from the staple.

The special features constituting my invention comprise a casing 17 secured to the door 11, a vertically slidable bolt 18 carried thereby and a bar 19 secured to the door 11 and engaging said casing 17, said casing 17 being preferably in one integral casting and comprising a base plate 20, a staple 21 projecting laterally therefrom and an outwardly projecting shell 22 having a closed outer face portion 23, a bottom 24 which is closed except for the presence therein of a vertical guiding aperture 25 for the bolt, a closed upper end, and plate sides 26 which are formed near the outer face portion of the shell with guiding and confining slots 27 which commence suitably above the bottom 24 and extend upwardly and then inwardly and are open at their upper inner ends, except as the material of the car door closes the same when the devices are applied thereto. \Vithin the outline defined by the top, bottom and sides of the shell 22 the base plate of the casing is open and said opening base plate 20 which is entirely open at its 'back, except when 011 the car.

The bolt 18 is adapted to have a vertical movement within the shell 22 of the casing '17 and is formed at its upper end with a' transverse member or bar 28, whose end portions extend within the slots 27 and are provided with knobs or handles 29 to be manually grasped when the bolt 18 is to be moved upwardly. The knobs or handles 29 are exposed outwardly beyond the sides 26 of the shell 22, as shown in Fig. 2, and at the back of the shell 22 the upper inner ends of the slots 27 are open so as to permit of the introduction of the bolt 18 through the back of said shell, the base plate 20 being recessed in line with the upper end of the slots 27, as at 30. The upper ends of the slots 27 turn rearwardly 011 an elbow curve and thereby permit of the convenient introduction of the bolt through the back of the shell 23 and the passage of the transverse bar 28 into the vertical portions of the slots 27, and in addition this formation of the upper ends of the slots 27 creates on the upper ends of the sides 26 of the shell 22 shoulders upon which the bar 28 may be rested when the bolt 18 is in its upper position and from which said bar may readily be arred so as to permit the bolt to descend in the event that the bolt should be left in its upper position and the car started in motion, the motion of the car being suiiicient to cause the bar 28 to leave said shoulders.

The staple 21 is in the form of a flat horizontal plate projecting outwardly from the base plate 20, and said staple is formed with a vertical hole 32 to receive the lower portion of the bolt 18 when the latter is in its lower position. The bolt 18 is formed with transverse openings 33 adapted to come one below and the other above the staple 21 to receive the wire or sheet metal of the seal 34, whereby the bolt is locked in its lower position and confines the hasp 13 upon the staple 21. I regard it as of particular importance that the openings 33 in the bolt 18 are so disposed as to come above and below the staple 21, since thereby without weakening the staple I am enabled to securely seal the bolt by a rod of wire or strip of metal engaging the bolt only. A special advantage of the upper and lower openings 33 in the bolt 18 over the use of a single opening in the lower end of the bolt, resides in the fact that when the sealing wire is placed through both said openings and sealed the .bolt cannot be opened without breaking the attention to the fact that the car has been entered.

The casing 17 will be secured to the door by means of bolts 35 and also by means of the bar 19, which near the inner edge of the door is recessed to receive the cross-section of the base plate 20, as shown in Fig. 3, and is also apertured to pass over the staple 21, and in addition the inner end of said bar 19 is formed with the right angular inwardly extending flange 36 to engage the inner edge of the door 11 and form an abutting surface to cooperate with a similar flange 37 on the inner end of the bar 14 secured to the door 12. I indicate at the reference numeral 38 the offset portion of the bar 19 affording a recess to snugly receive or fit transversely upon the base-plate 20. The bar 19 strengthens the door and aids in securing the casing 17 securely in place. The bars 19, 14 add greatly to the life of the doors in that they resist the wrenching action to which the doors are subjected tending to separate their parts during the travel of the cars.

In assembling the parts of the fastener for application to the car door, the bolt 18 is i inserted through the back of the base plate 20 and the cross-bar or head 28 atthe upper end of the bolt is entered into the guiding and confining slots 27 and thereupon the casing carrying the staple 21 will be bolted to i the door and then further secured by the application of the bar 19. i

The method of employing the fastening devices will be understood without detailed explanation. The staple 21 is in position to receive the hasp 13 and when it is desired to apply the hasp upon said staple the attendant will take hold of the knobs 19 and raise the bolt 18 sufficiently to allow the hasp to pass over the staple and thereupon .j

the bolt will be dropped so that its lower portion may pass through the staple and confine the hasp thereon. The seal 34 will then be applied and this will conclude the locking of the door.

The casing 17 is of particular importance in the details of its construction in that its shell 22 projects outwardly from the base plate and affords the guiding slots 27 in its sides for the cross-bar 28 on the bolt 18, said sides also aliording shoulders at their upper ends from which the cross-bar may be readily arred by the motion of the car should the bolt be inadvertently left in its upper position and on said shoulders. The open back of the casing is also of importance in that the bolt may be readily inserted through the same into the shell 22 and that whenever required the casing may be removed from the car door and a broken bolt be readily withdrawn and a new bolt substituted for it. The exposed knobs 29 on the ends of the cross-bar 28 of the bolt serve as convenient means for the manual handling of the bolt and also, being greater in diameter than the width of the slots 27, act to aid in guiding the bolt and in preventing sidewise tilting of the bolt at its upper end. The outer portions of the shell 22 being closed, the interior chamber of said shell is protected as far as may be possible from the entrance of dust, snow and the like.

The devices constituting my invention are durable and may be readily and securely applied to the door and conveniently manipulated in locking and unlocking the door.

What I claim as my invention and desire to secure by Letters-Patent, is:

1. In a car-door fastening, a hasp and cooperating means therefor comprising a casing having a base-plate, a staple to receive the free end of the hasp and a shell ofi'set from said base-plate, and a vertically slidable bolt mounted in said shell and adapted when in its lower position to extend through said staple and confine the hasp thereon, combined with a bar (19) secured to the dOOr having an offset recessed portion transversely crossing and receiving said baseplate and apertured to pass over said staple.
