FASTENING DEVICE FOR CAR-DOORS, 800.

SPECIFICATION forming part of Letters Patent No. 613,013, dated October 25, 1898.

Application filed March 21, 1898. Serial No. 674,672. (No model.)

T0 at whom it may concern.-

Be it known that I, GEORGE LIGHTHISER, a citizen of the United Sta-tes,residin g at Toled o, in the county of Lucas and State of Ohio, have invented a new and useful Fastening Device, of which the following is a specification.

My invention relates to looks and latches, and particularly to a fastening device adapted for use in connection with car-doors, barndoors, gates, &c.,the same beingconstructed for the use in connection therewith of a seal or a padlock; and the object in view is to provide a simple, efficient, and durable construction and arrangement of parts whereby qhe operations of lockin g and unlocking a door or gate are facilitated.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View of a locking device constructed in accordance with my invention applied in the operative position to a car-door, the parts of the lock being shown in their operative positions. Fig. 2 is a similar view showing the latch displaced and supported by one of the rests. Fig. 3 is a detail viewof the latch and swivel, showing the rear side of the former and indicating in dotted lines the contiguous portion of the securing-plate.

Similar numerals of reference indicate corresponding partsin all the figures of the drawings.

1 designates a hasp which is loosely mounted for universal swinging movement upon a staple 2, which. is preferably provided with a securing-plate 3, said hasp being provided in its edges with transversely opposite notches 4 and 4, and any desired number of sets or pairs of notches may be employed to suit the conditions under which the lock is to be used.

The other member of the lock consists, essen plate 9, which is common to and preferably carries the post 5, the swivel 10, to which the latch is connected by a transverse pivot 11, being mounted for revoluble movement on the securing-plate, whereby the latch is capable of universal swinging movement parallel with and perpendicular to the plane of the securing-plate.

Any suitable means may be employed for maintaining the latch in engagement with the fixed post 5, such as a seal 11*, for which purpose the said post is extended to form a perforated car 12, while the hasp is provided witha perforation 13, through which the sealwire may be threaded. It will be understood, however, that a padlock may be engaged with the perforated ear of the post 5 when the device is used in connection with barn-doors, gates, &c.

From the above description it will be seen that the opposite notches of the hasp are engaged, respectively, with a fixed projection on the securing or base plate (such fixed projection consisting of the post 5, having a notch or seat forming a shoulder behind which the contiguous portion of the hasp is fitted) and a movable projection on the latch; but in order that the said movable projection may be further braced than by the terminal engagement of the latch respectively with the swivel and the post 5 1 preferably provide the securing or base plate with a seat 14, into which the rear end of the lug 8 extends when engaged with the notch 4 of the hasp. This forms an interlocking connection between the parts, which insures the fastening of a door 15 or other sliding object in its closed position or in its adjusted position, as when, par

ticularly in connection with car-doors, it is desired to secure the same in a partly-open position to give ventilation to the contentsof the car. The lug 8*, however, performs an additional function which is desirable in this class of devices as facilitating the operation of releasing and opening a door to which the lock is attached. This additional function is performed in connection with rests 16, located, respectively, contiguous to the side edges of the securingplate or base-plate 9 and approximately in the horizontal plane of the swivel, said lug being engaged with one of these rests, as shown in Fig. 2, to maintain the latch in its inoperative or disengaged position, whereby the hasp may be readily disvan engaged from the fixed projection and used as a handle by which the door may be moved to its open position.

From the above description it will be seen that the device as constructed is simple and compact and the parts are so interlocked and braced to give the necessary strength to insure efficiency under such strains as those to which devices of this class are frequently subjected. Furthermore, it will be seen that the free end of the hasp 1 is tapered at both edges, or toward a central line, and that the post 5, with which the lower notch of the hasp engages, is beveled at its upper side or at the upper edge of the ear 12, and in connection with the hasp I preferably employ a guide or keeper 17 of such a length as to allow swinging movement of the hasp parallel with the planes of the base-plate 9 a sufficient distance to secure the proper engagement of the hasp with the post 5. Thus whether the lock em bodying my invention is used in connection with a sliding or a swinging door the hasp may be engaged with the stationary member or the post 5 without manual intervention. For instance, if the device is used in connection with the sliding door, such as a car-door, the tapered extremity of the hasp Will ride over the post 5 until the notch thereof drops into engagement, and if the lock is applied to a swinging door the lower edge of the hasp will ride upon the beveled upper edge of the ear 12 until it reaches the plane of the notch 6. It will also be seen that the hasp being reversible adapts the lock, which is otherwise .of reversible construction, to be applied to either a right or a left hand door, and a plurality of notches may be provided in each edge of the hasp to compensate for shrinkage or to enable the door to be secured in a partlyopen position.

Various changes in the form, proportion,

. and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is- 1. In a lock of the class described, the combination of a hasp provided in its side edges with opposite notches, a base-plate having a fixed projection for engagement by one of the notches of the hasp, and provided with a seat in registration with the other notch of the hasp, and a swinging latch having an opening to receive the fixed projection and carrying a rearwardly-extending lug to engage said registering notch and seat, substantially as specified.

2. In a lock of the class described, the combination of a hasp having opposite notches, a fixed projection with which one of said notches of the hasp is engaged, a swiveled latch, mounted for universal swinging movement, and provided with means for engaging said fixed projection, and with a rearwardlyextending lug to engage the other notch of the hasp, and a fixed rest arranged contiguous to the swiveled extremity of the latch, for engagement by said lug to support the latch in its inoperative position, substantially as specified.

3. In a lock of the class described, the combination of a hasp provided in its opposite edges with notches, a securing-plate carrying a fixed projection terminating in a perforated ear and adapted for engagement by one of the notches of the hasp, said fixed projection having a notch or seat to interlock with that of the hasp, and said securing-plate also having a seat in registration with the other notch of the hasp, a swivel mounted upon the securing-plate above said seat, a latch pivotally mounted upon said swivel, and having a slot to engage the fixed projection, and a rear- Wardly-extending lug to engage said registering notch and seat, respectively, in the hasp and securing-plate, and fixed rests carried by the securing-plate contiguous to and upon opposite sides of the swivel for engagement by said ing of the latch, to maintain the latter in its inoperative position ,substantially as specified.

, 4. In a lock of the class described, the combination of a hasp mounted for swinging movement and provided with a tapered free end and in its edges with opposite notches, means for limiting the swinging movement of the hasp, a fixed post having a beveled upper edge and cut away at the rear end of the beveled edge to form a notch for the reception of the lower edge of the hasp, and a swinging latch and securing devices for engaging the hasp and holding it in engagement with said post, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

GEORGE LIGHTHISER.
