ALFRED P. ALDRICH AND GEORGE BARKSDALE, OE GBEENWOOD, SOUTH CAROLINA.
SELF-LOCKING BOLT FOR EASZPS.
Application filed October 18, 1921. Serial No. 508,479.
To all whom z'zfilmag concern Be it known that we, Arrival) iiL-nnrorr and GEORGE E. BARKSDALE, both citizens of the United States of America, and residents of Greenwood, 1n the county of Greenwood. and State of South Carolina, have invented a new and useful Self-Locking Bolt ior Hasps, of which the following is a speciiication, v
-Our invention relates to improvements in fastening or locking means for hasps used on barn-doors, gates, cribs, and the like, and consists essentially of a bar which is adapted to be introduced into a staple after a hasp has been placed over or caused to engage the same, supporting means for said bar, and a gravity locking member adapted normally to prevent the withdrawal of the bar from the staple, together with such other parts and members as may be required or desired in order to render the device complete in every particular, all as hereinafter set forth.
Urdinarily a hasp of the class mentioned abovefis fastened in place, after being engaged with its staple, by means of a wooden pin or the like, that can be easily raised out of the staple so as to release the hasp, by a thrust from the nose of an animal, and the primary object of our invention is to produce a bolt which, while serving the same purpose as a pin, can not be removed by an animal inithe manner just explained, but can only be removed by a certain man ual operation such as no animal ordinarily A further object is to provide a bolt of this character which is not only strong and durable, but inexpensive, simple in construction and operation, convenient, and not likely to become impaired by exposure to the elements. i l
Other objects and advantages will appear in the course of the following description We attain the objects and secure the advantages of our invention by the "means illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a self-locking bolt for hasps which embodies a practical form of our invention; Fig. 2, an enlarged, left-hand edge elevation of the bolt shown in the first view; 3, a sideelevation of a bolt which is provided with two locking members, and, Fig. 4,. a front eles :vation of a modified construction.
latch is located.
lVhen the hasp 4- .is engaged with the staple and member is inserted in said staple in front of said hasp to prevent said hasp from becoming disengaged. from said staple, the door 1 is securely fastened to the frame 2. Upon removing the con-fining memberfrom the staple the hasp can be disconnected from said staple and the door opened. There is,
of course, nothingnew so far as themembers thus far described are concerned.
Referring first to the bolt illustrated in the first two views, it will be observed that the same comprises a bar 7, and a locking member or latch 8, and that said bar is suspended from a staple 9 set in the frame 2 above the staple 3, by means of a ring 10 and a cord 11. Any flexible supporting means may be substituted for the ring 10 and the cord 11, such as a chain. The lower terminal of the cord 11 passes through an opening 12 in the upper part of the bar 7. I The latch 8 is preferably in the shape of a channel-iron in cross section, of an interior width suiiicient to receive the lower terminal portion of the bar 7. The latch is connected with the bar by means of a pivot 13 which passes through the sides of said latch near the bottom and through said bar also near the bottom. The pivot 13 is so inserted in the latch 8 as to provide an axis for said latch which is offset relative to the longitudinal central plane transversely of said latch. on the sideof such plane that is opposite to that where the closed edge of the Thus it is seen that the latch will normally assume by the force of gravity an angular position relative to the liar 7 so that the upper corner, of said latch which includes the top of the closed edge thereof extends beyond the adjacent edge of said bar. substantially as shown infull lines in Fig. 1. This is the looking or open position of the latch. and the latter projects sufi'iciently to underlie thearm of the-staple 3 *8. '1 he parts are now disposed as shown in whichjisabove, consequently, if the bar 7 be raised while the latch is in such position, the projectingpart en counters said arm and prevents said bar from being Withdrawn from the staple 3. The bar 7 can, however, be made free for withdrawal li'om the staple 3, by rocking the latch S on the pivot 18, inwardly into closed position, so that it will not encounter or be interfered with by the staple when said bar is raised and drawn out of said staple. When the latch S is in the closed or unlocked position just described, it is disposed as indicated by dotted lines in Fig. 1.
In the first view a portion of the latch S is broken out to show at A the closed edge of which mention has been made, and to disclose the manner in which the outward moyement of the latch on its pivot 13 is limited. From the drawing it will be seen that, when the latch swings outwardly, the base of the member 14 comes into contact with the adjacent corner of the bar 7 and thus prevents the latch from moving outwardly at the top beyond a. predetermined distance.
'Pre' ferably the opening 12 in the bar 7 is located at one side of the longitudinal central plane transversely of said bar, with such plane between the center of said opening and the member 14 of the latch 8. The purpose of this is to cause the bar 7 to be suspended from the cord 11 in an oblique latch '8 to be closed in such a manner as to,
position the outer surface or face of said part in the same plane with the edge of "said bar above.
{In practice, after the hasp 4- has been placed over the staple 3, the bar 7 is. in-
fserted therein from above in front of said hasp, the latch then offering no resistance,
but rocking inwardly and outwardly on its pivot 13 at this time, and said bar is left suspended fromthe staple 9 by thering 10 and the cord 11, with said latch in open 'ppsitionbeneath said staple As prev ously explained, any effort to push the bar "(from below up out of engagement with the staple 3 is" frustrated by the latch full lines in Fig. 1. To unlock the hasp thelat'ch 8' with the thumb and fi ger '1I1 i}0 closed position, and push or avvthebar 7 upwardlyout of the staple 3. The hasp 4 can now be disengaged from looking position.
to close the latch 8.
the staple 3. The bar '7 is left suspended until it is required for use again. Thus it is plain that the device is ready at all times for use, can be placed in locking position instantly, automatically assume such position, and can readily be removed with the hand at any time.
Should occasion require, two latches in place of one may be employed, as illustrated in Fig. 3. in this example the latches are similar, but it is necessary, of course, to provide one, as 8, with an in terior width suiiicient to accommodate the other as well. as the'bar. In this construction two projections are pl'GVlflBCl forengagement with the two arms or the staple 3 in the event ar eiiort be made to raise the bar 7 out of said staple from below,.it be ing necessary to close both latches by hand before the device can be. withdrawn from In the double-latch construction the pivot 13is 'ofi' center relative to the latches, as in the first example, but ,7
the opening 12 is preferably in the longitudinal center of the bar, and said bar may have both eiilges cut away and shouldered as at 1515. 1
in the event it be preferred to incorporate the bolt with the hasp, rather than have the same suspended from a flexible member, we provide the construction illustrated in Fig. 1. Here the bar, as 7, isbent to provide an arm 16 that is pivotally connected at 17 with the hasp at, so that the bolt par-takes of the nature of a hook. The bar 7 is provided with a latch 8 as in the firstconstruc' tion, and the operation of the device is substantially the same except that it swings on the pivot 17 into and out of locking and un locking positions, instead of being lowered into and raised from such positions vertically. When the Fig. 4 bolt is in looking position it is supported by the arm 16 which then rests on one of the-arms of the staple 3. Before this bolt can be withdrawn from the staple 8, it is necessary, as in all cases, first As soon as the hasp 4'is engaged with the staple 3 the bolt can be permitted to drop into locking position relative to said staple and hasp, whichis the position shown in the view. Obviously the bolt must be swung upwardly on the pivot 17 far enough to clear the slot 6 in; the hasp 4 before the latter is placed over the staple 3.
More or less change in the size, shape, construction, and arrangement of some or all of the parts in this device,-in addition to those herein specifically shown and described, may be made. without departing from the spirit of our invention or exceeding the scope of what is claimed.
What we claim as our invention, and desire to secure by Letters Patent, is
1. As animprovedarticleof manufacture a bolt, of the class described, comprising a bar, and a latch, consisting of side and edge members, pivotally connected at the bottom end with said bar, and adapted to assume by gravity a projected position relative to said bar, the edge member of said latch being in {)uxtaposition to one longitudinal edge of the 2.
