Appli-cation filed January 29, 1917. Serial No. 145,297.

.To all whom t may concern:

Be it known that I, ALEXANDER CHRISTIE, citizen of the United States, residing at Seattle, in the county of King and State of Vashington, have invented a certain new and useful Improvement in Hasp-Fasteners, of which the following is a specification.

My invention relates to hasp fasteners for doors, and the object ofmy inventionv is to l rovide a hasp fastener which shall be-r adapted to be associated with a single door and its door frame, or to be associated with a pair of doors disposed in a' single door frame there to operate releasably and rigidly to lock .said door or said doors in a closed position. A further object of my invention is to provide a hasp fastener sok constructed that it will be particularly adapted to be associated with a pair of doors that is employed to close the rear entrance to a covered delivery'wagon, such as is employed by mercantile houses for delivery of merchandise, whereby said pair of doors may be releasably held in such tightly closed position as will effectively prevent a rattling or vibral tion of the doors of said pair irrespective of any ,wearv of the parts of said hasp fastener.

I accomplish .these objects by devices illustrated inthe accompanying `drawings wherein Figure 1 is a view in front elevation of a hasp fastener embodying my invention; Fig. 2` is a view in longitudinal section on broken line 2, 2 of Fig. 1, showing the same associated with a pair of doors. in their closed positions;

v Fig. 3 is a fragmentary view in front elevation of parts ofthe same, showing one part in vertical cross-section on broken line 3, 3 of Fig. 2; l

Fig. 4 is a planrview of the same, in association with a pair of doors, showing relative operative positions of the parts thereof; and f Fig. 5 is a fragmentary plan view of the same showing a modified arrangement of its parts.

Referring to the drawings, throughout which like reference numerals designate like parts, 5 and 6 represent a pair of doors which may be hinged at their outer side edges and adapted to close as illustrated in Figs. 2 and 4, against any suitable stop, as a door frame or stud 7.

A spring-like bar 8 of suitable metal, as

spring steel, is slightly curved to dispose its two end portions normally in planes that areat a slight angle to each other, as shown in Figs. 2 and 4, one of said end portions being providedv with holes 9, 10 :and 11, as indicated by dotted circular lines in Fig. 3, through which holes 9. 1() and 11 extend bolts, as bolts 13, whereby said springlike b'ar'S may be bolted to a door, as the door 5 in the manner shown in Fig.

Secured to the bar 8, between the heads of two of the bolts 13 and 14 and its outer side surface, is the base of a catch'12, of the form shown in Fig. 2. y

Bolted to the front side of the door 6, by bolts 14, is a bracket 15 to which is hinged one end of a straight latch bar 1G that is adapted to engage its inner'side surface, at avpoint near its hinged end, with the outwardly curved end portion of the bar 8 when it is actuated to swing to the position parallel with the front surfaces of thedoors 5 and 6, as shown in Fig. 2, whereby said end portion ofthe bar 8. will be pressed toward the door 6 and whereby the spring-like action of said bar will tend to press the latch bar 16 outwardly from its said parallel position adjacent to the doors 5 and 6. y

' Extending'through the latch bar 16, near its free end, is a slotted hole 17 through which ther catch 12 may project outwardly when said latch bar 16 is pressed toward the door 5to its position shown in Fig. 2; and the outwardly projecting portion of said catch 12 is provided with a hole 18 in which the loop of a padflock may be disposed, if

it be vdesired to lc'ck the doors 5 and 6.

y Fixed in the free end portion of the latch bar 16 is a rivet whose head 19 projects .from the outer side surface of saidlatch `bar 16 lto form afdetent,fand between said rivet and the slotted hole 17 isa hole through which extends the shank 20 of locking member 21 that is provided with a knob 22 and two lugs 23 and 24 which extend radially from said locking member 21.

The shank 2O of the locking member 21 is longer than the thickness of the latch bar 16 and its inner end is provided with a washer 25 that is fastened to said inner end by a screw 26; thus the locking mmber 20 may be drawn outwardly for the distance limited by said washer 25 so that, when required, the locking member 20 may be rotated without causing the lugs 23 and 24 to engage with the rivet head 19 thereby to obstruct the rotative movement of said locking member 20, as indicated in Fig.V 4.

If, however, the locking member 20 is locking member 20, while the l lug 24 is' adapted to engage with the catching surface of said catch 12 in response to a contraclockwise rotative movement of said locking member 20. VBut, such rotative movements can take place only Vwhen the locking member 20 is drawn outwardly to the point where the washer 25 will engage with the inner side surface of the latch bar 16, and, therefore in the operation of disposing the parts, as shown in Fig. 3, to lock the doors 5 and 6 it is necessary, first, to close the door 6 and then to close the door 5, whereupon the latch bar 16 may be swingingly moved to force inwardly the curved end portion of the bar 3 until the catch 12 projects through the slotted hole 17 for such distance that one of the lugs 23 and 24 can be moved to its lockingposition under said catch 12 while the locking member 20 is drawn outwardly to its fullest extent, and when if said lugs as, for instance, the lug 23, is in its locking engagement with the catch 12 then the pressure againstthe bar 16 is discontinued whereupon the force of the bar 8 will press the bar v16 outwardly to the position shown in Fig. 2 so that the rivet head 19 will engage with the lug 24 to prevent further rotation of the Vlocking member 20 until the latch bar 16 is again pressed inwardly.

' To unlock the doors the bar 16 is first pressed inwardly to permit the locking member 20 to be drawn outwardly till it can be turned without being obstructed by the rivet head 19 whereupon the lug 23 may be disengaged from thecatch 12 in an obvious manner to permit said latch bar 16 to swing outwardly from said doors 5 and 6.

side of the latch bar 16 in a position to en-V gage its other end portion with the outer surface of the door 5 when said latch bar 1 6 is in a position to lock the doors 5 andy 6;

said spring-like bar 28 thus taking the place of the bar 8 of Figs. '2, 3 and 4 to perform the same function by the same mode of operation.

AIf my hasp fastener is to be used in con- 'nection with a single door then the bracket 15 is fastened tothe door frame of such single door inV the same ymanner that it is fastened tothe door 6 of Figs. 2 and 4.

Obviously, `changes may be made in the forms, dimensions and arrangement of parts v of my invention without ydeparting 'from the spirit thereof. Y Y

What I claim is: A hasp fastener comprising a provided with Ya hinge on one of itsl end portions to adapt it to vbe hinged toa door frame, and provided with two holes disposed to extend through its other end portion; a locking member provided with a Vcylindrical shank and a radially projecting locking'lug7 said shank being rotatably disposed within one of said holes and being adapted tol be moved in endwise'directions therein; adetent fixed on said latch bar and disposed tov adapt it to engage with said locking lug in response to a rotative movement of said locking member when said locking lug is in engagement with the adjacent side surface of said latchbar; a catch adapted to Lproject through the otherl of said holes to make locking engagementv with said locking lug; and a spring associatedl with said latch bar in a position to adapt it to .exert a pressure against said latch bar when said locking lug is in engagementwith said catch.l Y v Y In witness whereof, I hereunto subscribe myname this 17th day' of .Ianuary'A D.,

ALEXANDER cHRisTIF...
