instan Jiirans Cjrnr'r'rs," or "sCRAN'roN, PESYAMA' CARLDOOR' Loon.

f a'ppneation' flied Aprn s,

of Scranton, in the county of Lackavvanna and State of Pennsylvania, lhave invented a certain new and useful Improvementvin lar-,Dooi-Lockswof which improvement the following isa specification. l v

invention relates to locks for car doors, Tand .moreparticularly for the doors of box yfreight cars. Heretofore it `has been thev practice to lock the, doo-rsl of such` cars byfmeansl of the usual bolt: orpin which'is then, fasteed ,by e wire end 'leedeeatte prevent removal. This means for securing they lockl ha showeven'fproved to be very inadequate, as the wires and sealslare quite easily broken and manypthefts yhave been committed by breakingdthehlocks lin this manner. 'Ihe use of padlocks and keys has also been proposed, but this is inconvenient and unsatisfactory, since the keys are often lost or find their way into the hands of dishonest employees, or other unauthorized persons, who thus obtain access to the cars.

The object of my invention is to provide a car door lock of simple, strong, and durable construction, and having a sliding bolt adapted to be securely fastened by a transverse rivet, with means for preventing the easy removal of said rivet.

The invention claimed is hereinafter fully set forth.

In the accompanying drawings: Figure l is a side elevation of a portion of a box freight car, showing one form of my improved lock, applied thereto; Fig. 2, a side view, in elevation, of the lock upon .a larger scale; Fig. 3, a transverse section through a portion of the car frame and car door, showing the lock partly in end elevation and partly in section; and Figs. e and 5, horizontal sections taken on the lines a a and b b, respectively, of Fig. 3.

In the practice of my invention, referring descriptively to the specific embodiment thereof which is herein exemplified, the lock comprises two portions, the housing portion, adapted to be attached to the door, and the bracket portion, adapted to be fastened to a fixed part of the car body or frame. The housing portion is preferably formed of a casting, 1, provided with lateral flanges, l, for the reception of fastening bolts, 2, and having an opening through the full length of the casting for a sliding isaz. asel-iai No. 550,597.

'b1t,""3; "ne batsman pianta with a transverse. stop pin, 3, in the cored pas- Seae; tvh'eh, sepen ,et the back insertion :of thestop pin, before the housing is belted te the deer, 7- The Steppin lmite the vertical orusliding movement of the bolt Within-.the Casting Forkthe purposefoffastening the bolt in itslower or lockingpositiom I provide a transverse rivet, or locking pin, 5, lextending through openings'in the castingy and in the bolt, which openings register,l with 'njeach other inl thisposition o fthe holt, the riyet being then headedjfoverfat itsend'tolsecurelv fasten vthe bolt and preventnits removal. The rivet is preferably termed. with@ recess in its endto facilitate the operation of head-l ing over the rivet upon the housing.

In order to hold the rivet or locking pin during the riveting operation, I may provide a flange or wall, 1c, formed integrally upon the casing at the outer side of the head of the rivet, whereby a piece of iron 0r other wedge may be inserted between said wall and rivet head to act as a backing Iand permit one man to head the rivet over quickly and efiiciently. As shown in the drawing, the wall, 1, is joined at its outer end with the main body of the casting form-l ing a vertical opening, l0, in which the wedge may be inserted. rI`he .wa-ll, 1c, is also provided with an opening, 11, in line with the rivet for permitting the same to lgeliuserted through the casing and sliding Another feature of my improvement consists in providing means for protecting the headed over end of the rivet, such as the lugs, l", formed upon the casting, both above and below the end of the rivet, whereby it will be diliicult t0 obtain access to the rivet with a tool for the purpose of filing or cutting off the end of the same.

'Ihe bracket portion, 6, of the lock is shown as rigidly secured to the car sill, 8, beneath the car door, by bolts, 9, said. bracket having an opening through which the bolt, 3. extends, when in locking position. The bracket may be formed of acasting of any suitable shape or size. It will be obvious that when the car door is closed and locked, with the bolt securely held in place by the rivet, it will be extremely diiiicult for thieves to break the lock without making considerable noise and disturbance,

,ef the, casting, as shown Lkin Figs. 3` and 4, for the sage, a bracket adapted 'to be secured to the i whiehlvvould betray their operation. `When v it is desired to open the car door'by those If desired, the bolt, 3, inay also be secured vby. a Wire and seal connection passing through suitable holes in the bolt and in `the housing-or bracket. f y
