OF CHICAGO, ILLINOIS.

Application. filed: August 6,

Tamil. whom it may concern Be it known that. 1, JOHN Enanin, citizen of the United States, residing at Minneapolis, in the county of Hennepin. and

State o'li Minnesota, have invented certain new and useful Improvements in Convertible Stock and Freight Cars; and I do hereby declare the following to: be a full, clear,

and exactdescription of the invention, such as will enable others skilled in the. art to which. it appertains to make and use the same.

My present invention relates to box cars and is directed to the improvement of the side door structures. Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined inthe claims.

Box cars for .hipping various kinds of.

goods or materials must be completely closedstructures, while for the shipping of live stock, they should be more than well venti lated, that is, should have large openings or air passages through the side door openings through which light, as well as airmay pass in a very free manner.

My invention combines sliding gate bars with the sliding side doors of box cars in a novel manner, hereinafter described, and

whereby the side door openings may be entirely closed, entirely opened, or closed by moreor less of the gate bars, at will, and whereby the desired. results above indicated may be accomplished.

The invention is illustrated in: the accompanying drawings wherein like characters indicate like parts throughout the several views.

Referring to the drawings:

ing a portion of the door and means for locking the same tothe car body".

The body of the box car is indicated by the numeral (3 and its side door openings by the numeral 7'.

Each door opening 7 is adapt-ed to be opened and closed bya sliding side door 8 secured to horizontal upper and lower sliding bars 9 and- 10 arranged to move, respectively, above and below the door opening 7. T he upper bar 9 is arranged to slide through guide brackets 11 fixed to the side of the car, while the lower bar 10 is shown as arranged to slide through a guide bracket 12 and guide lug 13 securedon the side of the car body. The upper bar 9 is about three times as long as the door 8 is wide, and the said door is secured to the intermediate portion thereof. The lower bar 10 is a little more than twice as long as the door 8 is wide and the said door is secured to the right hand portionv thereof, directions being taken in respect tov Figs. 1 and 2.

The door 8, at its left hand edge, as viewed in Fig. 1, is provided with a laterally inwardly projecting flange allorded by an angle iron 171i riveted, bolt-ed, or otherwise rigidly secured thereto in such manner that the flange oi? said angle will engage the door post 15 when the door is moved outward, or to an extreme open position.

Mounted to slide through openings in the door post 16 that is opposite to the door post 15, and to move within the side of the car between the inner and outer sheathing, is a plurality of horizontally disposed vertically spaced gate bars. 17. At their outer ends, these gate bars are provided with latch plates 18 formed on their under edges with lock notches 19, and, at their outer ends, with undercut cam surfaces 20.

The door posts 15 are provided with pockets- 21 with which the beveled, or undercut, ends of the latch plates 18 of gate bars 17, engage. The inwardly projecting flange of the angle bar 1 1 is provided with slots 22 through. which the outer end of the latch plates'18 may be projected, so as to engage their notches 19 with the said flange, and thereby interlock the gate bars to said angle 14: for sliding movements with the door 8.

The pockets 21 in the post. 15 are so located that when the ends of the latch plates 18 are, by opening movement of the door 8,

y when free, will moved into the pockets 21, the latter will hold the same down and positively interlocked to the flange of the angle bar 14, so that it will be impossible to disconnect the gate bars from the door, or from thepost- 15, when the door is in extreme open position.-

The gate bars are adapted to be slid back into the wall of the the door passage completely open, or entirely free for passage therethrough. lVhen the door is slid to the left, or slightly toward a closed position, the outer ends of the gate bars may be raisedso that their latch plates may be freely moved endwise, either into or out of interlocking engagement with the flange of the angle bar 14. It therefore follows that all or any desired number of the gate bars may be interlocked to the door. Obviously, for keeping hogs in a car, more of the gate bars will be required than for keeping cattle, for example, within the car. The above arrangement provides for such, and other adjustments. Obviously, when the gate bars are locked to the door flange and the door is secured in its extreme open position, as above described, there is no possibility of animals within the car disconnecting the gate bars from the door and door post.

lVhen the door 8 is slid, .its guide bars 9 and 10 move with it through the guiding devices described. F or looking the door, at will, either in a closed position, or in an extreme open posit-ion, I provide a lock device which comprises an upright rock shaft 23 mounted in bearings 24;, and 25 secured on the outer side of the car body, preferably to the door post 16, bymeans of screws, bolts, or other suit-able devices, Rock shaft 23 is capable of slight vertical, as well as oscillatory movements, and it is provided at its upper and lower ends witheccentric lock lugs 26 that are engageable -with lock notches, or

detents

27 and 28 formed in the door carrying and guiding

bars

8 and 9. When lock lugs 26 are engaged with notches 27, the door 8 will be locked in its extreme open position, but when said lugs 26 are en gaged with notches 28, the door will be locked in its closed position.

Rock shaft 23 is provided with an arm 29. the hub of which is rigidly secured to said rock shaft and is provided with a beveled undersurface 30. that is engageable with av correspondingly beveled upper surface of the shaft bearing 25. The arrangement of the said beveled surfaces is such. that, under the action of gravity, the rock shaft 23,

swing into a position to engage its eccentric lock lugs 26 with the

notches

27 or 28, according to which are aligned therewith. In its free end, arm 29 has a slot 31 that adapts it to be passed over a perforated lug 32 secured on the outer surface of the door 8, when the said door is in car body, so as to leave a closed position, and lugs 26 are engaged with notches 28. Either a padlock or a seal passed. through the lug 32 when'it is projected through the arm 29 will serve to lock the latter and thelugs 26 in position to positivelynlock orholdthe door in its closed position.

Itwill be'noted that, in view of the above described tendency of the rock shaft 23 to swinginto a door closing position, it will hold the lock lugs 26 against the bars 9 and 10 when the door '8 is in an intermediate position, and will automatically swing its lugs into the aligned

notches

27 and 28, so that the door will be automatically latched or locked in either extreme position to which it is moved.

lVhat I claim is:

1.. The combination with a. car body having a door opening, of a door mounted to slide on said car body to open and close said door opening, and a plurality of gate bars slidably mounted in the car body for movements across said door opening and having separate detachable interlocking engagementwith said door, and whereby they may be slid with the door or disconnected therefrom.
