5 Claims.

This invention relates to fastening devices,

especially to looks, and more particularly to a proved hasp-lock fastening devices for use as standard equipment upon aseries of cabinets installed along the right-of-way of a railroad and intended for containing operating relays, tools and supplies, etc.

It isdesi-rablethat such cabinets be secured against accessto their interior by unauthorized persons, but readily accessible to numerous in dividual operatives each provided with a master key adapted to lock andunlock. all the padlocks by which term the fastening devices for such cabinets are known generally to such operators, whether or not they include aconventional padlock orany suitable locking device not operable by hand without some form of key or actuating member.

Other objects and advantages will appear as the" description" of" the particular physical. embodiment selected to illustrate the invention progresses, and the, novel features will be particularly pointed out in the appended claims.-

In describing the invention in detail and the particular physical-embodiment selected to illustratetheinvention, reference will be had to the accompanying drawing and the several views thereon; in which like characters of reference designate like parts throughout; the several views, andtin which:

Figure 1 is a view in horizontal section of a hasp-lock fastening deviee',1in the construction of which the invention has been" embodied, and shown in position upon the associated parts of a cabinet to whichit is applied including portions of the door-frameandswinging door; Fig. 2 is a front elevational view of the device as shown by Fig; 1, with some parts broken away to more clearly show the construction; Fig. 3 is a View inside elevation'of the device shown" in Figs. 1 and r 2; Fig; 41s a detail view like Fig. 3, but showing the keeper member separately; Fig. 5- is a plan view of the mounting pivot memberfor the hasp, taken separately; Fig. 6 is a fragmentary, detail view like Fig. 1, but showing a modification.

Inth'e-now preferred embodiment of the invention selected for illustration, and referring first to Figs. 1 to 5 inclusive, the reference character ll designates generally a swinging door, such as the door of a cabinet of the type known as a relay cabinet, being one of a series installed along the right-of-way' of a railroad, the door frame being designated generally as l2, while [3 designates an inner panel, adapted to. be engagedv with a rabbetedportion I4 of the: upright free edgeofthedoor,.which it is desired to bring into firm, snug'contact therewith.

In pursuance of the invention, 1. provide a hasp lock fastening comprising a hasp-element 15 mounted pivotally near the upright edge of the door, and carriedv bodily by the door, being also adapted. to swing about its pivot into juxtaposition with a keeper element I6- when the door is.

closed.

The hasp element: includes amounting plate or. member. I! of. asize and: shape suitableto fitwithin a yoke l8 formed at the pivot end of the hasp' member, this mounting. plate being; secured to the door by abolt lfltransfixing the door and mounting. plate, the latter having an opening. 2!}v throughv which the: bolt passes, and wings 21 so" spaced as to accommodate the squared head 22 of the bolt, preventing it from being'turned from the outside of thedoor. The inside" end of the bolt 23 is provided with theusual nut and washer securement.

The outer faces of the wings and adjoining part of the mounting plate l1 are shown as provided with open sockets 24- to receive the pivot posts 25- with which theJyoke: l 8is furnished, and spurs" 26: may be provided to prevent turning movements of the mounting plate, so that: when the hasp member i5 is swung out of engagement with the keeper [6 it: will: be maintainediin its horizontal plane.

The shank ii! ofthe hasp member may desirably be trough-shaped in. cross-section for the sake of strength with lightnessandat'itsfree end the hasp has a head. 28 in. which is. fitted=a setscrew'29which is provided witha part 30'designedi to serve as means'to permit the screw to be operated readily by hand, f-or lockingpurposes.

In the form of construction shown in Figs. 1 to 4 inclusive, the manual: operating means takes the: form'sof a wing-nut, fixed by a pin 3| to the shank of set-screw 29, and either'wing, or both wings. 32' of this nut may be desirably pierced, as at 33, to receivetheloop 3'4 of aconventional pad lock 35.

When the padlock is in. place,.its loop 34 hangsbetween the flanges 36 at each sideof thetrou'gh shaped portion 21 of the hasp member, so that the wing nut cannot be turned until an operator provided with a key opens and removes the lock 35.

The keeper element I6 is of improved construction especially designed to cooperate efliciently with the hasp element, to hold the latter in its adjusted position securing the door H snugly against the frame members l2 and I3.

5 For this purpose, the keeper element has a ridge 3! around the seat 38 against which the nose of the set-screw 29 bears, and this ridge prevents any chance of a. lateral escape by slipping of the set screw when the latter has been firmly driven in home.

The preferred shape and extent of this ridge 3'! is best shown in Fig. 4, from which it will be clear that the part 3'! constitutes a substantial barrier against the introduction of a tool, such as a screw-driver, in an effort to reach and displace the set screw 29.

Such tampering is further prevented by a high wall part 39 of semicircular contour, reinforced at its rear by a buttress 40. The keeper also is made with a stout L-shaped base having a lug 4| secured to the door-jamb l2 by screw 42 which is protected by the hasp member 21 from being withdrawn when the door is closed; and the base plate lug 43 may be desirably secured firmly to a 25 square headed wood screw 44, or other suitable securement, according to the character of the cabinet to which the device is applied.

It will be readily understood from the foregoing disclosure that the hasp-lock-fastening 'device is very strong, sturdy, economical to manufacture and to install; cannot be readily removed, and is proof against tampering unless the latter be studied and carried to a destructive extent, and even such malicious interference will be at least discouraged if not prevented to a large extent.

The same is true of the modification illustrated in Fig. 6, which is merely illustrative of a considerable range of diverse forms in which the into vention may be embodied by those skilled in the art, upon the basis of the disclosure found herein.

Fig. 6 shows a set screw which has a noncircular head 45 adapted to receive a removable operating key 47 in place of the wing nut 30 shown 45 in Fig. 1, but otherwise operating in the same manner.

It will be noted that the head of the hasp element is provided at 48 with a protective wall which extends to a distance sufiioient to prevent 50 easy operation of the set-screw 45 when the key 41 is not in place. This form of device is available for many applications of the device where the risk of interference is less than warrants the provision of a conventional padlock, and in fact the form of lock shown in Fig. 6 may be, and is, regarded as a padlock in the terminology of railroad equipment.

Although I have particularly described one particular physical embodiment of my invention and explained the operation, construction and principle thereof, nevertheless, I desire to have it understood that the form selected is merely illustrative, but does not exhaust the possible physical embodiments of the idea of means underlying my invention.

What I claim as new and desire to secure by Letters Patent of the United States, is:
