To all tf1/1,0m, t may concern.'

-Be it known that I, HERMAN AHEEND, a citizen of the United States, residing at Newark, in the county of Essex New Jersey, have invented certain new and useful Improvements in Locks; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had .to the accompanying drawings, and to letters of reference marked thereon., which form a part of this specification.

The present invention relates generally to improvements in locks which are especially adapted for use with trunks, coat-cases, and the like, and the invention refers more particularly to a novel construction of lock for trunks and the like, comprising a lower faceplate and main boX or casing containing the lock mechanism and an upper plate, which is separable from the lower plate and is provided with a spring-actuated hasp or catch adapted to be brought in locked engagement with the lock mechanism automatically without the use of a key, but being disengaged therefrom only by means of a key.

My present invention has for its principal object to provide a lock, knownas a tumbler-lock, of the character and operating in the manner hereinafter more fully set forth, which shall be neat, strong, and durable and shall be self-locking, whereby the lock is especially adapted for use with trunks. Thus with trunks when the tumbler mechanism of the lock is actuated by means of a key the spring hasp or catch is released from engagement with a slide-bolt, its spring automatically forcing the hasp outwardly to permit the lid of the trunk to be raised. At the same time the tumbler mechanism and slidebolt are held in their fully-operated and unlocked position by the action of a springplate. As soon as the lid is again closed the spring-actuated hasp or holding-catch can be pushed in engagement with said spring-plate, thereby releasing the tumbler mechanism and slide-bolt, which are thus automatically brought in their self-locking relation with the hasp or holding-catch.

rlh'e invention is clearly illustrated in the accompanying drawings, in which Figure l is a front face view of the lock, showing in connection therewith a portion of a trunk-body, a portion of its lid, and a part and Stateof scale.

of the valance arranged about the lower marginal edge portion of the lid ,and Fig. 2 is a rear view of the lock. Fig. 3 is a transverse vertical section of the parts of the lock, showing the lower face-plate with its boX and the lock mechanism therein and the upper face or hasp plate with its spring-controlled hasp shown in locked engagement with the slidebolt of the lock mechanism; and Fig. 4 is a similar section of the same parts, showing the hasp in its disengaged relation. Fig. 5 is a plan view of the boX or casing detached from the back of the main face-plate, showing the parts of the lock mechanism in their normal initial positions, with the key, represented in cross-section, shown arranged upon the key post or stud Fig. 6 is a similar view of the same parts, ,with the key partly turned to' show the positions of the tumblers and the slide-bolt intermediate of their normal initial positions and their fully-operated positions; and Fig. 7 is a similar view of the same parts, showing the fully-operated positions of the tumblers and the slide-bolt, said views showing in connection therewith the various relative positions of a retaining lor holding spring-plate. Fig. 8 is a vertical cross-section taken on line 8 8 in said Fig. 5, Fig. 9 is a similar section taken on line 9 9 in said Fig. 5, Fig. 10 is a similar section taken on line l0 l0 in Fig. 6, and Fig. l1 is a similar section taken on line l1 11 in Fig. 7, all of said sections being made on an enlarged Fig. l2 is a horizontal section taken on line 12 l2 in Fig. 5, and Fig. 13 is a similar section taken on line 13 13 in Fig. 7, both of said sections being made on an enlarged scale and looking in the direction of the arrows shown in said Figs. 5 and 7 Similar characters of reference are employed in all of the above-described views to indicate corresponding parts.

Referring now to the several figures of the drawings, tliefreference character 1 indicates a portion of the box or body of a trunk or the IOO like, 2 a portion of its lid, and 3 is a part of the usual valance which is secured about the marginal edge portion of the lid.

The reference character 5 indicates the lower face-plate of the lock, the same being provided with perforations for fasteningscrews 4 or other means, such as rivets, for securing the face-plate upon the front of the trunk box or body. The said lower faceplate is provided with a keyhole 6 and a receiving-opening 7 for the reception of the IIO holding or retaining portion of the hasp, which is connected with an upper face or hasp plate 8 in the manner to be presently described. Connected with said face or hasp plate 8 is an outwardly-extending member or element 9, forming, with said face-plate 8, a chamber 10, provided in the bottom with an opening 11.

The tace or hasp plate 8 and its parts is secured in its operative position by means of screws 12 or any other suitable fastening devices.

Movably connected with the ,upper faceplate is a hasp 13, the same consisting of a cross-bar 14, having a cam-shaped portion 15, said bar 14 extending across the chamber 10 and having its opposite ends projecting from suitable openings 16 in the opposite side walls of the member or element 9.

Connected with each tree end portion of the bar 14 are arms or members 17, formed with a connecting portion 18, which provides a suitable iinger-piece and is made upon its back with a holding or retaining portion 19, adapted to enter the receiving-opening 7 in the lower face-plate 5.

A spring 20 is arranged within the chamber 10 with its central curved portion 21 bearing, under normal conditions, when the holding or retaining portion 19 is in engagement with the slide-bolt of the lock mechanism, as will hereinafter appear, forcibly against the cam-shaped portion 15 of the bar 14, as indicated in Fig. 3 of the drawings, but said spring 2O automatically forcing or springing the hasp 13 to the position shown in Fig. 4 of the drawings as soon as its holding or retaining portion 19 is released from engagement with the slide-bolt of the lock mechanism, owing to the pressure of the spring upon the cam portion 15 of the bar 14, whereby a slight rotative movement of the hasp is produced.

The lower Jface-plate 5 is formed with an enlargement 22 and an upwardly-extending post or lug 23, which enters the opening 1 1 to prevent distortion of the parts when secured in their respective positions upon the trunkbody and the lid.

Suitably secured upon the back of the lower face-plate 5is a suitably-constructed box or casing 24, preferably by means of perforated ears 25 and screws 26, 'substantially as shown in Fig. 2 of the drawings. The said box or casing 24 is provided upon its back with a key-receiving post 27 in alinement with the keyhole 6 in the plate 5, said back being provided also with

posts

28, 29, 30, and 31.

Slidably arranged between the two posts or

studs

28 and 29 is a slide-bolt 32, having the oppositely-placed and longitudinally-extending slots or

open portions

33 and 34, respectively embracing the

posts

28 and 29. Said slide bolt or plate 32 is recessed, as at 35, for the engagement of the tongue 37 'of a key 36 with the said bolt or plate 32 for moving it in the direction of the arrow i/ in Fig. 6 of the drawings against the action of a spring 38, which has its coils arranged upon the post 31 and its

end portions

39 and 40, respectively, in engagement with an edge 41 of the bolt or plate 32 and the inner wall of the box or casing 24. Near its opposite end and contiguous to its slot or open portion 34 the slide -plate or bolt 32 is provided with an upwardly-projecting stud or lug 42, forming a stop, for the purposes to be presently more Yfully described. Upon its upper edge the said slide plate or bolt 32 has an upwardly and slightly outwardly projecting member 43, which is formed with a forwardly and longitudinally extending linger 44. Under normal conditions the said finger extends over the freely-movable end portion 46 of a flat spring-plate 45, which plate is secured at its opposite end, by means of a rivet 46, to the inner face of the back of the box or casing 24.

Oscillating upon the post or stud 28 is one, two, or more tumblers 47, each tumbler being provided at the end opposite from its point oi' pivotal support with a longitudinally-extending slot or opening 48 and a cutaway or recessed part 49. In a slot 50 or otherwise secured to the opposite end of each tumbler is a spring 51, each spring having its 'liree end portion 52 in engagement with the post or stud 30. rl`he purpose of these springs is to force each tumbler, under normal conditions, in a downward direction, so that the oi'liset formed by the cut-away part 49 of each tumbler will be in engagement with the stud or lug 42 of the slide plate or bolt 32,whereby the parts are held in their normally inoperative positions, as will be clearly evident.

Having thus described the general construction and arrangements of the various parts of my novel construction of self-locking lock, l will now briefly describe the operations of the several parts.

Suppose the holding or retaining portion 19 ot the hasp 13 has entered the receivingopening 7 in the lower face-plate5 and has depressed the free end portion of the springplate 45 to the position indicated in Fig. 3 oi the drawings, at which time the iinger 44 of the slide plate or bolt 32 has entered into its locked or holding engagement with the member 19 of the hasp 13, and it is desired to unlock the parts to bring the hasp into its released position. (Shown in Fig. 4 of the drawings.) As soon as the inserted key is turned from the position shown in Figs. 5 and 9 of the drawings successively to that in Fig. 6 and finally to that illustrated in Fig` 7 of the drawings the tumblers are raised sufficiently to disengage the oiiset of each tumbler free from the stud or lug 42 of the slide plate or IIO ISO

bolt 32. The key thus moves the slide-plate in the direction of the arrow y, thereby withdrawing the finger 44 from its holding engagement with the member 19 and the latter being released is forced outwardly, as shown. At the same time the finger 44 is moved away from over the springplate 45 (shown in Fig. 12) to the position indicated in Fig. 13, the end 53 of the finger being thereuponforced in engagement with the end 54 of the spring-plate 45, which end is preferably bent for strength, as shown, or for the purpose of preventing the finger 44 slipping back over said spring-plate when. the latter is made of thin metal. When the parts are in the positions just described, being retained, as indicated in Fig. 7 of the drawings, the key is removed and the lid of the trunk can be opened. To again close the lid of the trunk, all that is necessary is to bring the lid down so that the parts are in the positions shown in Fig. 4, and as soon as the holding or retaining member 19 is again inserted in the opening 7 of the lower face-plate 5 said member 19 again engages the free end portion of the spring-plate 45 and releases the end of the finger 44 from the end of the plate 45, as will be clearly understood. In this manner all the parts of the lock mechanism return to their normal initial positions (indicated in Fig. self-locking lock has been produced, which is very simple in its construction and most effective in its operation.
