Description
April 9, 1929. F. J. GILROY DEIICE FOR SECURING CAR DOORS Filed Aug. 29, 1924 2 Sheets-Sheet Illa. lll l llllllllllllllllll April 9, 1929.
F. J. GILROY DEVICE FOR SECURING CAR DOORS Filed Aug. 29, 1924 2 Sheets-Sheet till Spring M, and allowing the keeper to engage the loar I in such manner that it can he disengaged only by rising of the piston, that is by air pressure below the latter.
Bolts V pass through the door and the plates T. T, the holts lieing provided with annular shoulders to receive the plate T and with nuts, sunk in depressions in the latter, so that when the door passes to fully open position, the nuts may treely pass the post II, which is recessed to receive the keeper, as shown in Fig. 7. \Vhon an all metal door is used, the plate T is omitted and a keeper V, Fig. 8, is riveted at V directly to the door. The keeper T of the main torn: is provided with a meinhrr X which whin t door is closed covers the end of the inn I and prevents it from heing depressed by one within tho car.
It is to he noted that the liolts V have heads which cannot he engaged tor rotating them, and that even it the heads he out oil h -i one outside the car, they still hold the plate T. It is also true that opening or closin the air valve will he without eti'ect in the al=- emergency application oi the ldahe. as is.
also with other related devices.
It is also of importaure that the lat hing devices are so tar ahove the ground that they cannot roadilyhe reached without a ladder or other devi es tor which the wor am who tampcrs with similar looks has no legitimate use, there hoiug no rea on tor hi:v acting at such height. for any proper purpos Furthor. one inside the latched car mount manually depress the lover and open the car tor escape.
It follows that even it a pore n is well advised of the specitic construction, it is practically impossihle tor him to open the car through tampering witl its tast'enings.
The hook R of tho keeper-engaging end of the har I and the lip R which it engage: are very important, for without them it is possihlo to use a thin wedge gently urging tho door to open, and then lily light han'imering on the lower end or bond of the pipe N, the lever will he slightly tilted and trietionally held against return. Repeated blows may thus progressively depress the engaiziing end of the har until the door is released. lVhou the hook and lip are present, the application of door-opening force, at once engages the hook and lip and such tilting of tho liar or lever is prevented.
\Vhat I claim is:
1. The combination with a vehicle. of a pivoted door holding latch lying inside the outer sheathing ot the vehicle ahove the load line, of a spring normally holding said latch in latching position, a keeper provided with means for interlocking with said lever when moved in an opening direction while said lever is maintained in latching position and a reciprocating lover releasing means adapted for operation only by the sudden supply ot a relatively large volume of compressed air.
2. Tho combination with a door holding latch lying within a car wall ahovo the load lino ot' a keeper carried hy a car door for engaging the latch provided with a guard which when engaged with said latch completos the inaccessihility ot the tastonings from within, or without tho car, said fastenings lioing roloasahle only lay a reciprocating piston adapted tor operation lrv the sudden supply of a relatively large voluszio of compr ssod air.
I). The comhination with an inaceessihlo latch i'or holding a air door closed. oi moans whorchy the latch may oe released by com lil HHt'ti air from a iocomotivo or the like. said latch and keeper hoing proi'idod with a roar "ardly open recess and a rearwardly e. tending hook tor interlocking said latch and its keeper wherehy releasing is prevented hy opening torce applied to the door.
at. The oomhination with a railway carhaving a door trout recessed almve the load line to receive a swinging latch and a door-carried keeper provided with an integral guard to engage the latch a ad render its engaging end p rtion inareessihle. said latch lioing disengagod only h a la ge volume ol' highly compressed air supplied t'rom and controlled h}? devices ot a locomotive or a like distant r-pouroo.
The eomhination with a car having tho usual dooroponing posts, of latch devices carried in a recess in one post. a wood door provided with metal plates holtod to its opposite 'laces in tho horizontal planeor.-- aid ro- ('(1'2 a keeper integral with tho inner of sa d plates and prtyiocting when the door is open into a recess in the taco oi the post past which too door moves in opening, said inner plate and the holts which see 1o it. hoing sunk in the door so that the latter may slide close alongside the post.
6. The combination with a railway car having a sliding door, of a pneumatically released latch having a lever concealing casing, a keeper having an integral protecting shield For the engaging memhors of said latch, said engaging members having interlocking portions which engage when opening force is applied to the door.
7. The combination with a vehicle provided with a door, of a resiliently held pivoted latching lever provided with an integral guard and with means for interlocking with a keeper, a keeper provided with cooperating interlocking means and with a guard for said lever, and means for unlatehing said door only by the sudden supply ot a. large volume of compressed air.
In testimony whereof I hereunto afiix my signature.
