LEE P. HYNES, OF CHICAGO, ILLINOIS, AfssIdNon TORAILWAY UTILITY COMPANY, OE
CHICAGO,,'ILLINOIs,vl A CORPORATION on ILLINoIs.- L
'sLILING-nooa FASTENER.
To all whom it may concern:
Be it known that I, LEE P. HYNES, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and4k use' ful Improvements in Sliding-Door yFasteners, of which the following is a specifi.-l cation. I n
My invention'is especially designed and. adapted to meet the requirements Iof locks for the doorsof freight ears, though, "as will be seen from the following description therefof,r it is well adapted-to sliding doors for other purposes. Withthe ordinary haspv andk keeper now in common use for freight, car doors, they latter are apt to be left unsecured and. free to slide by inadfvertence on the part of the*y railway 'employees 'orfreighthandlers, and the doorsare. also frequently left open 'purposely for the sake of ventilation. When the car is moved. with thedoor unsecured, it is driven backward and 'forward by they starting, stoppingjand jerkingr ofthe train and comes violently into contact.y
with the door j-amb at one end of its movements and with the stop which: limits its movements in the other direction, and .is-4
ultimately racked to pieces or injured, to-
such an extent that the car is put out of' commission until repaired. When such/'av door is equipped with one-of. my locks',` how-y ever, or preferably with two of. them, one at either end of its path, .it is automatically caught and held the first time it is driven into engagement with the lock and further shifting prevented. If `but one look is employed of' course it is arranged; upon the jamb or stop bar on the doorway to secure the door in closed position, but where it is desirable to also secure the door in openy position a lock is suitably located to :engage with the lrear edge of the :door when the latter is open.
kIn order to meet thecondjitionsy imposed by freight car construction, it is necessaryy that the catch of thelock yield'readily-under the impact ofthe door to permit the same to come to locking position an-d. withoutundue strain'upon-the parts, and that it shall noti involve any small or delicate partsl which are apt to besheared by the impact of. the door. f It is further necessary., in view`- the partsinterlock notwithstandin'gra .con`- Specification of Letters' Patent.

Applicationfled.J'u1y1',v1912l. SerialNo. 706,885.
guished by the fact ythatgthe parts thereof may be cast in `their ultimate form, thus doing away with any expensive machining or vfinishin In: the accompanying drawing I have illustrated the preferred embodiment of my invention, and in the fol-lowing speoication I have described the. same in detail, but it is to be understood that the disclosure of this specific' form is for the purpose of exempliication only and that my invention is not limited' thereto, but itsscope is defined in the following claims.
In the drawings forming part of the application, F igurel represents a side view of a portion of a freight car, showing so much thereof including a doorway and door, as is necessary to an understanding of my inventionk; Fig. 2 is a front elevation of a portion of a jamb and door respectively having the members of my lock attached thereto; Fig.4 3fisia vertical section upon the line 3 3 of Fig. 2;` Fig. 4 a horizontal section upon the line 4 4 of Fig. 2 and Figs. 5, 6, 7 and 8 are isometric views of details which are `described specifically below. The parts are designated by the same symbols of reference wherever they occur yin the several views.
The freight car 9 and door 10 may be of any usual or approved construction, the latter being suspended by roller brackets 11, 11 upon a track' 12 and retained against the car by guides 13, 13 as usual in such construetion's. I have shown in the drawings a single lock A and keeper B attached to the door jamb' and door respectively, but as stated above, if yit bel desired asimilar lock and keeper may be mounted upon thel stop which limits the opening movementfof the door and upon the other edge of the door respectively, ifit'be desired to lock'the door in open position. l The keeper B consists of a face plate 14 formed withl a pocket 15, the front wall 16 of which is substantially perpendicular to the face plate, the rear wall 17 and side walls 1 8, v19 being inclinedas shown. The specific shape of :thisk pocket is Anot essential hown ever, but that shown is convenient for the reception of the catch of the lock and also for application to the door, it being only necessary in order to accommodate the keeper in position on the door to saw kerfs at the proper distance apart and substantially at the angle of inclination of the end walls of the cavity, and to remove the intermediate block by means of a chisel, the cut being made upon the angle of inclination of the rear wall of the cavity. The face plate is provided at its upper and lower edgesrespectively with cam projections 20, 2l 'for a purpose which will appear, and is secured to the door by bolts 22, 22.
The lock proper is composed of a pivoted latch member 23, a pivoted dog 24, a face plate 25 and a housing member 26, shown assembled in Figs. 2 and 3 and detached in Figs. 5, 6, 7 and 8. rllhe latch member 23 is preferably cast integral and comprises a barrel 27 which constitutes the pivot thereof, a-
strap 28 projecting from the barrel intermediate its ends and substantially radial thereto, and a cammed catch 29 consisting of a triangular wing extending ina plane substantially at right angles to the strap 28 and offset from the axis of the barrel 27. A lug 30 projects from the face of the catch 29 at right angles thereto and is of such length as to be engaged by the upper cam projection 20 upon the keeper face plate when the latch is rotated or swung to a position in which said lug extends upwardly, asexplained below.
The lock face plate 25 is formed near its upper end with a rectangular pillow block 3l the outer face of which is cylindrically concave, and at its lower end with a transverse corrugation 32 the inner face of which forms a bearing for the pintles of the dog 24 when the parts are assembled. A longitudinal slot 33 formed partly in the plane portion of the face plate and partially in the corrugation, receives and provides. for the pivotal movement of the dog 24. The latter consists of an irregularly shaped plate 34 provided with trunnions 35, 35, a linger hole 36 and a transverse opening or slot 37, which last, when the strap 28 is in engagement with the dog, is in register with a pair of similar slots 39, 39 in the strap 28, which slots may be used for sealing the lock if desired by inserting an ordinary or suitable seal therethrough.
The housing member 26 comprises a plane attaching plate 40 and a semi-cylindrical cover or housing 41, having an end wall 42, and adapted to fit over the pillow block 31 and to constitute with the latter a substantially cylindrical bearing for the barrel 27 o-f the latch. The housing is cut away intermediate its ends as at 43 to provide for the projection therethrough and swinging movement of the strap 28 of the latch.
The lock may be attached to the stop bar 44 without any preliminary preparation of the latter, and is assembled by thrusting the dog 24 through the opening 33 in the lock face plate until the pintles 35 thereof enter the corrugation 32, and projecting the strap 28 of the latch through the opening 43 in the housing until the barrel 27 occupies the concave thereof, the housing member then being applied to the lock face plate over the pillow block 31 and the whole structure attached to the stop bar by bolts driven through the bolt holes 45, 45, 45 of the face plate and the bolt holes 46, 46 of the housing plate.
When the lock has been thus assembled and secured to the stop bar as above described and the keeper plate properly located upon the door to coperate therewith, the latch 23 normally hangs substantially vertical whether the door is open or closed, the dog 24 projecting through the longitudinal slot 47 in the strap with its cammed lip 4S occupying a. position over the lower edge of the slot in the keeper as shown in Fig. 3. The engaging surfaces are such, however, that outward pressure exerted upon the strap readily lifts the dog to permit the strap to swing upward. If the door is closed the catch 29 of course rests within the pocket of the keeper B and the lock may be either secured by a padlock, the bar of which is passed through the finger hole 36 in the dog, or by a seal passed through the transverse registering openings 39, 37 in the strap and dog respectively, or by both if desired. To unlock the door it is only necessary to remove the padlock and seal if such have been attached as described, and swing the strap upward thus withdrawing the catch from engagementwith the keeper. In order to close the door it is only .necessary to throw it to closed position when the lip of the outer wall of the keeper wipes upon and past the carnined edge of the catch, ro tating the latch until the outer wall of the pocket in the keeper passes beyond the nose of the catch, when the latter swings into the pocket, the strap at the same time swinging into vertical position in engagement with the dog as before described. lf by any chance the latch is swung upward so far that it is caught or lodged with the strap and lug extending upwardly from the barrel thereof, movement of the door brings the upper cam 20 into engagement with the lug and dislodges the latch which swings to normal position. rllhe additional cam 21 on the keeper plateperforms no function in the construction when mounted as described but is only provided so that the keeper may be used in a reverse position with a lock of reverse construction, as for example, when a lock is to be applied to the rear edge of the door for holding it open. The pillow block position for cooperation with the keeper,
and the end wall 42 upon the housing mem ber receives the-shock and longitudinal pressure transmitted to the latch barrel permitting the latch to rotate easily under the pressure, `when the door engages the'same.
It will. now be seen that l have provided a lock which is rautomatic in its action and therefore prevents the destructive movements of the car door to which it is attached,
which is readily formed by casting the parts without any machining or other expensive manipulation and which does not depend for eii'fective operation upon nice adjustment oi3 the parts but will act. notwithstanding considerable vertical or lateral variation in the relative positions of the parts. It possesses the further advantages that it holds the door f from lateral swinging when in engagement therewith and projects but slightly from the side of the ear or into the opening therein, thus avoiding to a large extent Contact with passing objects.
