HASP-LOCK.

Specification of Letters Patent.

Patented May 28, 1907.

Application led August 5, 1905. Serial NO- 272,835.

To LZZ whom it may concer-71,:

Be it known that I, WARREN K. BLODGETT, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Hasp-Locks, of which the following is a specification.

This invention relates to hasp-locks for use in securing transportation companies against the unauthorized opening of doors of freight-cars and other receptacles; and particularly to Lthat class of hasp-locks employing a hasp retaining member, a lock-casing, and a seal-strip of resilient material such as sheet metal, the hasp-retaining member and lock-casing having each a passage for the seal-strip which extends through both and unites them, when properly assembled, and the lock-casing and seal-strip being provided with locking members which are caused to automatically interlock by the operation of inserting the strip into the lock-casing. It is to be understood, however, that I do not limit myself to the particular use referred to in connection with doors, since the parts may be employed to lock or secure other relatively movable structures. l

One of the objects ofmy invention is to provide a hasp-lock, of the character mentioned, so constructed or arranged that access to the seal-strip at or adjacent to the point where the strip joins the two membersv will be prevented, so that it would be impossible for an unauthorized person to break or cut the seal-strip at this point and then conceal the tampering by soldering the two parts of the severed strip together.

Another object is to provide a construction in which the mouth of the seal-lock is clutched in position to relieve the neck of the seal from undue strain.

Another object of the invention is to provide a structure in which the hasp-retaining member and the lock-casing, each having a passage for a seal-strip, can readily be brought into alinement and contact for the proper insertion of the seal-strip, but cannot e improperlyl connected so that a seal-strip can be inserted in an incorrect way.

Another object of the invention is to combine the hasp-retaining and locking members as inseparable parts of a single structure which will be'interchangeable on all car doors, whether rights or lefts; making unnecessary the construction or installation of the lock-casings as rights and lefts; which will allow the seal-strip to be always inserted (whether on right or left hand doors) with the right hand if desired; and which will make unnecessary the printing of the seal-strip on both sides in order to accommodate it to opposite positions on different car-doors. 4

To these ends the invention consists in the construction and combination of parts substantially as hereinafter described and claimed.

Of the accompanying drawin s:-Figure 1 represents a front elevation o a door and casing with devices including one embodiment of my invention attached thereto, the parts being represented in unlocked osition. Fig. 2 represents a side elevation from the left of Fig. 1, omitting the hasp and its supporting member. Fig. 3 is a view similar to Fig. 1, with the parts in locked position. Fig. 4 represents a Section on line 4 4 of Fig. 3. Fig. 5 represents a section on line 5 5 of Fig. 3. Figs. 6, 7, 9, 10 and ,12 are views similar to Fig. 3, but illustrating modified arrangements or different constructions of the device. In Figs. 9, 10 and 12, the drawing of the hasp has, to economize space, been omitted. Fig. 8 represents a side elevation of the hasp-retaining and locking member shown in Fig. 7. Fig. 11 represents a section on line 11-11 of Figs. 9 and 10. Fig. 13 represents a section on llne 13-13 of Fig. 12. Fig. 14 re resents the bolt or pin shown in Fig. 12, etached from the lockcasing.

The same reference characters indicate the same or similar parts throughout the several views. A

Referring first to Figs. 1 to 5, inclusive, portions of a door and a casing therefor are indicated res ectively at 20 and 21. These parts, 20 an 21, however, may be understood to represent other relatively movable parts which are to be locked together. For convenience of description, however, I shall hereafter refer to them as the door and casing respectively.

The hasp or shackle 22, which may be of an ordinary kind having an eye-hole or slot 23, is connected to the door 20 by a suitable eye or staple 24, so that said hasp or shackle may be conveniently shifted from the position shown in Fig. 1 to that indicated in Fig. 3. It is obvious that on left-hand doors, the

ICO

IIO

hasp will be on the left side of the casing, and on right-hand doors on the right-hand side of the casing.

Suitably secured to the casing 2l is a baseplate 25, having upper and lower eye- lugs 26 and 27 respectively, the eyes of said lugs being adapted to carry the bolt or hasp-retaining member 28. As best shown in Fig. 4, the eye of the upper lug 26 is larger than the eye ot the lower lug 27.

The hasp 22 is adapted to be engaged with the upper lug 26 by being slipped thereover to the position shown in Figs. 3 and 4, said upper lug 26 being preferably provided with a notch or recess 39 in its upper surface near the base-plate, so that the hasp when swung to will be positively held in the position where it will not interfere with the movements of the bolt or hasp-retaining member 28 and will leave the door 'fastened even when unlocked.

i@ The bolt 28 is formed with a head 29 suiriciently large to prevent its passage through the eye of the lower lug 27, said head, however, being adapted to freely enter the eye of the upper lug 26. Said head 29 prevents the bolt from dropping entirely away from the lower lug, as shown in Fig. 2. The bolt, 28, is limited to a vertical movement and prevented from any sidewise or turning movement, preferably by making the eyes of the lugs 26 and 27, Oval in shape, and that portion of the bolt which plays through them, a similar oval, one diameter being sulliciently larger than the other to prevent turning the bolt in the eyes. The same result may be accomplished in other ways, as by making the bolt and the eyes rectangular or other- Wise irregular inform, or by placing stops on the surface of the lug which engage suitable projections on the bolt. One side of the bolt 28 is formed with a recess 30, of such size and shape as will admit the entrance of the end of the lock-casing 34, from the bottom of which recess slot 3l extends through to the opposite side of the bolt, so as to form a passage for the seal-strip. The bolt 28 is formed with a hole 32 from which a link 33 depends loosely, absolutely preventing the removal of the bolt upward Jfrom the lugs, and said link being pivotally connected, also, with the lock-casing 34 makes both bolt and lockcasing permanent or inseparable parts of the whole fixture. The mutual adjustment of said boltfhole, link, and lock-casing is such as4 to enable the lock-casing to move only (except for a little necessary play) in the circumference of a circle whose radius is just su'llicient to let the entrance tip or mouth of the lock-casing. reach into the recess 30 against the seal-slot 31, and in combination with the immobility of the bolt horizontally, to prevent the entrance tip of the lock-casing from being brought up against the seal-slot on its back side or in any other incorrect way; and also to prevent the. wrong or exit end of the lock-casing Vfrom heilig brought up to the recess 3() in locking position under any circumstances. ln order, turther, to prevent the wrong or exit end ol? the lockcasing from being carried to a position on the back of the bolt where the lock might be imperfectly sealed by a reverse motion, the link may be wholly prevented from swinging on the wrong side of the bolt, it desired, by a suitable enlargement or stop on the bolt; but l prefer to construct the lock-easing itself in such a way as te prevent the \\rong end from reaching the seal-slot by providing a toe 38 projecting from the rear end ol" the casing, or to so construct the loelvcasing internally that a seal-strip cannot be passed through it which enters at its exit end.

lt is not necessary to illustrate or describe the details of the internal structure oll the lock mechanism cmlnaced. in the easing IH., since devices are well known in which a easing and a resilient seal-strip are provided with locking members which automatieally interengage when the strip is moved in one direction into or through the. easing, but which prevent the strip from being removed from the casing in the return direction. l have represented the passage l'or such strip as at 35 and the strip itsell at S6, the said strip having a widened portion or head $37. As will be readily understood, the strip 36 is designed to be introduced through the. slot 31 of thebolt and thenv into and through the passage 3.5 in the lock-casing SH until the head 37 reaches the outer surface, ol. the bolt 28, as indicated in Fig. I3. At this point the interengaging members (not shown) olI the lock and seal-strip will hold the seal-strip so that it cannot be witlulrawn, thereby necessitating the breaking or tearing ot the head 37 to-enable the bolt to be withdrawn l'rom its hasp-retaining position. (lt course, when the parts are to be changed from the position shown in Fig. l to that shown in Fig. 3, the hasp or shackle 22 is irst engaged with the upper lug 26, as liercinbel'me described, the bolt 28 is moved upward to the. position shown in Fig. 4 and then the lock-easing IH is swung around so that its tip enters the recess 30 in the bolt. This results in bring ing the passage 35 of the lock into alinement with the slot 31 of the bolt, so that the sealstrip may be readily inserted as described.

In Fig. 6 I represent practically the same details of construction as in Figs. l to 5, but with the plate 25 and its parts reversed, so that the bolt will be. moved downward instead Of upward when passing to position to cross the hasp or shackle.

It is obvious that in Figs. l to 6 the link instead of being attached to the bolt, might, if desired, be attached to the baseplate itsell', by forming a small extension. or ear projected suitably downward or outward, as in IOO llO

Figs. 7, 9, 10 and 12, but this would require an eXtra fastening to prevent the withdrawal of the bolt from the lugs. It is also obvious that the link might be separated from the structure and attached to the casing immediately below or above the structure, in the same relative position as when attached as herein described; but this has the additional disadvantage of making the lockcasing a separate piece, with an extra cost of attachment, more easily capable of loss, and requiring skill and knowledge in suitably attaching it to the car-casing and adjusting it to the other members.

In Figs. 7 and 8, the bolt or pin is eliminated; the baseplate is formed with a vertical lug 60, which is the hasp-retaining member, and which has at a suitable point in one side, arecess 62 of such size and shape as will admit the entrance of the end of the lock-casing 34,*with a slot or passage 61 extending through from the bottom of the recess to the opposite side of the lug, to form a passage for the seal-strip through said slot and into the lock-casing, when the latter is inserted in the recess. In this form of lock, the hasp or shackle 22 is, ofcourse, formed with a vertical slot 63' to enable it to pass over the vertical lug 60. The baseplate is extended downward and outward in an ear 64 to a point where the connecting Vlink 65 may swing pivotally, carrying the mouth of the lock-casing to the recess in substantially the same manner as described in connection with the forms previously illustrated.

In Figs. 9, 10 and 11 the kconstruction and operation are quite similar to that in Figs. 1 to 6, but the bolt or hasp-retaining member is composed of a strip of sheet metal 40 bent at one end to form a handle 41, by which it may be moved upward or downward but is prevented from being removed from the rixture, and provided with. an offset' portion forming a recess 44, said offset portion being formed with a slot 45, as shown in Fig. 11. The baseplate 25 is formed with a small extension or ear 46, projected downward or sidewise and outward, to which is pivotally connected a link33, the lock-casing being pivoted to the other end of said link. It is obvious that,l if desired, the link may be connected to the handle or head of the bolt as in Figs. 1 to 6. In this form the end of the lock-casing is formed with an extension or yoke 47 forming a recess which will receive the offset portion 44 of the bolt. The passage 85 in the lock-casing will be in alinement with the passage 45 of the offset or recessed portion 44 of the bolt, when the parts are interengaged as shown in Figs. 9, 10 and 11, so that the seal-strip may extend through both to join the two members. In this form it may be said that each member has a recess which receives a portion of the other member, since the onset 44 forms a recess on one side and the yoke 47 of the lock-casing forms a recess which receives a part of the bolt 40.

In Figs. 12, 13 and 14, I have shown the bolt or pin 72 of sheet metal, bent at its head 41 to prevent its removal downward, and twisted below its center to prevent its removal upward through the vertical slot of the upper lug g and I have shown the lockcasing 34 formed with an extension`70 havingv a vertical opening or recess that is substantially rectangular in cross section. The outer wall of said recess is formed with Aa slot 71 in alinement with the seal-strip-passage 35 within the casing. The bolt is adapted to rest and be guided in a vertical slot formed in the lug 26 and an eye in the lug 27 of the baseplate. Said bolt 72 is formed with a slot or passage 74 which, when the parts are in position to receive the seal-strip, will be in alinement with the passages 35 and 71 of the lock. The extension 70, having the vertical recess, has the lower opening partly closed and the portion of the bolt 72 which'projects through said lower opening is narrower than the part above, thus making an enlargement or shoulder 75 serving as a protection for the lower oriiice, and preventing the insertion of a iile or saw from below, for the purpose of severing the seal-strip; a second and similar enlargement 76 is made on the bolt 72 where it emerges from the upper orifice of the recess, and for a similar purpose, as shown in Fig. 14. It is obvious that the vertical opening or recess instead of being rectangular, may adapt itself to any form of bolt desired, whether sheet metal or iron casting, circular, oval or irregular.

It will be seen that I have provided a structure inA which the bolt forms a hasp-retaining member, and the casting 34 and the parts contained therein form a locking member for said hasp-retaining member; these two members having passages for the sealstrip which extends through both, and the two slots or pasages being in alinement when brought to the position which they must occupy Jfor the insertion of the strip the bolt or hasp-retaining member having a recess which receives the tip portion of the other, and thus prevents access to the strip at or adjacent to the point where the strip joins the two members, and also, by clutching the top and bottom and two sides of the lock-casing, when in position, in combination with the link, assists in preventing the swing of, and in carrying the weight of, the lock-casing, and thus in taking a portion of the strain oil the neck of the seal-strip. It will also be seen that I IIO have provid-ed a structure, with the help of f casing to hang, balanced, when not in use, with sufficient movement from the motion of the car to free it from sand or snow, and to yield Without injury if struck; and also in Which the link assists in carrying the Weight of the lock-casing when locked in position. It will further be seen that I have lessened the danger (found in the ordinary method of hanging the lock-casing and bolt each by a separate chain, the lock from the door and the bolt from the casing) of the separation of one or the other from the structure, I have avoided the changes necessary in making the lock casings rights and lefts on account of right-hand and left-hand doors; I have avoided the necessity of sealing one half the locks with the left-hand; and I have avoided the necessity of printing the seal-strip on both sides in order to enable it to be read either in a right-hand or left-hand lock.

I claim:

l.. A hasp-lock comprising a hasp-retaining member having a transverse seal-strip passage, and a movable locking member for said hasp-retaining member, said. locking member having a seal-strip passage extending from end to end thereof, whereby a sealk strip will hold the locking member in endwise position relatively to the hasp-retaining member.

2. A hasp lock comprising a hasp-retaining member and a movable locking member for said hasp-retaining member, said members having each a passage for a seal-strip to extend through both, one of said members having a recess to receive a portion of the other member for the purpose of preventing access to the seal-strip at or adjacent to the point where the seal-strip joins the two members, and by clutching the mouth of the locking member in position, relieving the neck of the seal-strip from undue strain.

3. A hasp lock comprising a hasp-retaining member and a movable locking member for said hasp-retaining member, said. members having each a slot or passage for a ralstrip to extend through both, the passage through the locking member extending longitudinally thereof and one of said members having a recess to receive a portion of the other member, the passages of the two members being in alinement when a portion. of one member is in the recess of the other member.

4. The combination with a hasp, of a retaining member therefor and a locking member for the retaining member, said members being formed with passages for a sal-strip, the passage through the locking member extending longitudinally thereof, the retaining member having a recess to receive the tip or end of the other member when. the two members are assembled with their passages in alinement.

5. A hasp lock comprising a hasp-retaining member andv a movable locking member for said hasp-retaining member, each of said members having a passage for a seal-strip to extend through both, the passage through the locking member extending longitudinally thereof and said members having means to prevent their being incorrectly assembled.

6. A hasp lock comprising a hasp-retaining member and a movable locking member for said hasp-retaining member, each of said members having a passage for a seal-strip to extend through both, the passage through the locking member extending longitiulinally thereof and said. members being formed to permit the hasp to be swung to and. engaged by the hasp-retaining member from the right side or from the left side of the latter.

In testimony whereof I have allixed my signature, in presence of two witnesses.
