HINGE LOCK.

Application filed May 26,

T all whom it may concern: Be it known, that I, LUDWIG Scorn, a citizen of the Republic of Switzerland, residing at Edgewater, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Hinge Locks, of which the following is a speolhcation.

This invention relates to nnprovements 1n hinge locks, particularly locks for the hinges of step v ladders, when these ladders are to be used as straight wall ladders with their uprights locked in alignment.

Another object of the invention is the pro- I vision of a hinge lock for the locking of sliding doors or hinged doors for preventing the entrance of burglars, etc., who may be successful in opening the customary door locks.

These and other like objects, which will become more fully apparent as the description progresses, are attained by the novel construction, and combination of partshereinafter described, and shown in the accompanying drawings, forming a material part of this disclosure, and in which- Figure 1 -is a top plan view of a hinge lock constructed according to the present invention, particularly adapted to lock the hinges connecting the uprights of a step 13d. der.

Figure 2 is a side view thereof.

Figure 3 is a detail side elevation of the locking member of the lock.

Figure 4; is'a detail side elevation of the keeper member of the lock.

Figure 5 is a fragmentary top plan view of the locking member. s

Figure 6 is a top plan view of the keeper member of thelock.

Figure 7 is a top plan view of a modified form of hinge lock constructed accordin to my invention and adapted forlocking s iding doors. I

Figure 8 is a top plan view of another modified form of my invention adapted for use with the customary hinged doors.

Figure 9 is a sectional side elevation of the keeper member of the hinge lock, Fig. 8.

Figure 10 is a view similar toFigure 9 of, the locking member, and

Figure 11 is a sectional side view of both members in engagement, the section being taken along line 1111 of Figure 8.

To the upper edges of the uprights 10 and 11 of a step ladder or the like are secured by means of the screws 12 or the like,

1921. Serial No. 472,841.

the foot plate 13 of the locking member, and the foot plate'l l of the keeper member.

The plate 14 is provided with longitudinal slots 15 forallowing an adjustment of the plate 14' of the keeper member by a correspondingadjustment of the screws 12 with respect to the upright 11 for a purpose which will be hereafter more fully explained.

The uprights 10 and 11 of a step ladder are connected at their lower edges by the customary hinges'16, and the plate 13 of the locking member is provided at its inner upper end with an upstanding lug 17pr0- jecting somewhat over theouter upper end of the upright 10 to engage in' a recess 17 of the upright 11 and having a central bore for the reception of the pintle 18 to the ends of which at both sides of the lug 17 the

ears

19 and 20 at one end of the locking element or 'hasp 21 are secured. Said hasp 21, is provided near its other end with-a longitudinal slot for the passage of the car 22 on the plate 14"through which in thelocked position of theparts the shackle of a padlock 23 may be guided, as indicated in dotted lines in Figure 1.

The inner end of the plate 1 1 is provided with two hook shaped projections 24' and 25,

adapted to be engaged, when the parts are in their engaged locking position by lugs 26 at the end of locking member or hasp 21 laterally disposed to the

ears

19 and 20.

It will be clear that in place of the padlock an ordinary plug may be used and passed through the ear 22 of the. keeper member above the locking member when it has been passed through the slot of said member in order to lock the uprights or bars 10 and 11 of a step ladder in alignment when the ladder is to be used as an ordinary straight wall ladder.

In the modified form of hinge look illus trated in Figure 7, which is preferably to be used for the locking of sliding doors, the base plate 27 of the locking member 27 is attached to one part 28 of a sliding door by means of screws 29 or the like, while the keeper member 30 has longitudinal slots 31 and is attached to the other part 32 of a sliding door by means of the screws 33 allowing an adjustment of the keeper member with respect to the door part 32. c I

The lock'ng member 27' has earsor perforated lugs 34: at the side edges of its inner end through which are passed pintles 35 around the inner ends of which are guided the forked ends 36 of the locking member 27.

The keeper member 30 has at its inner end a hook 37 adapted to engage between the forked ends 36 of the locking member and with its front end, when the locking member is in the position illustrated in Figure '7, the inner end wall of the same between said ends 36. It will be clear that this engagement of the hook 37 will prevent an opening of the sliding doors when the parts are in the position shown in Figure 7, while a turning of the locking member 27 upon its base plate 27 will disengage its end wall from said hook so that both parts of the sliding door are free to be opened and closed.

In the modified form of invention illustrated in Figures 811 inclusive, a door 38 is fastened bymeans of the customary hinges 39 to the door frame 40- in the well known manner.

To the door 38 the base plate 41 of the locking member 42 is attached by means of screws 43 or the like, and the inner end of the plate 41 has upstanding lugs 44 perforated in their center for the reception of the pintles 45 around the inner ends of which are rotating the forked ends of the locking member 42 which are shaped into ears 46.

The keeper member comprises a base plate 47 adapted to be secured to the door jamb 48 by means of pins or screws 49. or the like engaging longitudinal slots 50 of the plate 47 and allowing a sliding movement of the same relative to the door jamb. This member 47 has an upstanding ear 51 intermediate it-s ends adapted to be passed through a longitudinal slot in the locking member 42 and to receive the shackle of a padlock 52 as indicated in dotted lines in Figure 8. i

, The outer end of thezkeeper member 47 is adapted to engage within a socket 53 secured to the door jamb 48 by means of a screw 54.

A leaf spring 55 is inserted in the socket 53 in the manner shownin Figure 8 so that the outer end of the keeper member 47 engages with this spring during the sliding movement of the member 47 on'jamb 48 in which it is held by the slot and pin connection 49, 50.

The inner end of the sliding keeper plate 47 has a hook 56 adapted to engage the inner end wall 57 of the locking member 42 when the same is swung around into its locking position in which it engages the up per face of the keeper member 47 as illustrated in Figure 11.v The end wall 57 is formed with a groove in which the hook 56 engages.

While the lugs 44 project somewhat over the inner end of the member 41 the hook projects over the inner end of member 47 and it will be clear that in order to allow an opening of the door after the locking member 42 has been swung around its pivots into the position, Figure 10, the member 47 with its hook must be somewhat withdrawn or moved backward against the action of spring 55 in order to allow a proper disengagement of the parts and an opening of the door 38.

Having thus described my invention, what I claim as new and desire to protect by a United States patent is:

1. A hinge lock of the character described comprising a slotted locking member, a base plate to one end of which said locking member is pivotally secured, and a keeper member, a means for normally pressing said keeper member into locking position, said keeper member adapted to be secured to a door, an eye in said keeper member adapted to be passed through the slot in said looking member and to receive the shackle of a padlock when said members are in alignment for locking them in this position.

2. A hinge lock of the class described comprising a slotted locking member, a base plate to one end of which said locking member is pivotally secured, a keeper member, two hooks atthe inner upper end of said keeper member adapted to engage shoulders of said locking member when the parts are in their locking position, and an eye on said keeper member intermediate the ends thereof adapted to be passed through the slot in said locking member when both members are in alignment and to receive the shackle ofa padlock for keeping the locking member in position in. said keeper member.

3. A hinge look of the class described for doors comprising a slotted locking member, a base plate for said locking member adapted to be secured to a door, a keeper member adapted to be slidably secured to the jamb of a door by a pin and slot connection, a socket on said jamb into which one end of said keeper member engages, a spring in said socket normally pressing said keeper member into its locking position, a hook at the inner end of the keeper member adapted to engage a groove in the end wall of the locking member, and an eye on said keeper member adapted to engage and pass through the slot in said locking member for the reception of a padlock shackle guided through said eye above the locking member, and means for rotatably securing said locking member to the inner end of its base.

In testimony whereof I have aflixed my
