Application filed May 12, 1919. Serial No. 296,375.

To all whom 'it may concern.' i Be it known that I, JOHN lVoLF, a citize of the United States, residing at Topeka, in the county of Shawnee andState of Kansas, have invented certain new and useful Improvements in Locks, ofA which the following is a-full, clear, and exact description,- reference being had to the accompanyin drawings,forming a part hereof.` f

. .Thepresentrinventionlis directed to improvements inl lid fasteners, and particulai-ly! to trunk-lidfasteners usually employed in conjunction with the-lock Aby whichxthe lid is locked to the bodyfof vthe-trunk. The object of the invention is to construct a fastener that is simple, durable, effective, cheap, and quickly manipulated, and one possessing further-'and other advantages better apparent from? the following detailed description in connection with the accompanying drawingsin which-.- Y Y g `FigureVl'represents atop plan of. a wardrobetrunk showing my invention.: applied thereto; Fig. 2 isl a front elevationof the upper end of the trunk with `my fastener in place; ,'Fig. 3 is a top plan of the fastener, partV of the upperwall being broken away; Fig. 4 isla middle'longitudinal section on the-line 4--4V of FigA 3 with trunk and lid walls'i-nsection;` Fig. 5 `is a"bottom plan of the fastener showing the operating parts ex'posedyFig. 6 is a-transverse section'on the lined-Gef Figf4 ;4 Fig. '7 isa detached per-Y spective of the locking bolt;` and Fig. 8 is a side elevation of the fastener.

r .Referring to the drawings, T, represents themain section of the trunk, T the horifzontally -swinging vertical section hinged thereto, 1L, the lid hinged to the section Tf, and A: the Ilockbywhichtheilid is lockedto the sectionf-T, theusual valance b being secured to the section v"l" and lid L 'as' well understood in the art, the sections parting along theseam a' covered by the valance. The. fastener comprises a keeper 1 in the rform of van oblong. shell or casing, preferably secured by means of-two prongs ornails 2, 2, formed integrally with the longitudinal wall of the shell and driven through the plate or fitting 3 and. valance b secured` to thewall ofy the lid L as shown. The keeper lwhen the lid L is-closed forms a continuation or extension of the shell or casing 4 secured to the trunk section T, said casingbeing open at one end andmcunted onthe plate Aor fitting 5 to which and to the trunk section T the same is secured by means of the teeth or prongs 6 disposed on the edges ofthe end and side walls of the casing, said teeth being driven through the fitting well into thel wall of the trunk Fig. 4). Vhen thelid L is closed the shells 1 and 4 constitute in effect a single casing forthe inner operating parts of the fastener. Formed at intermediate points along the edges of the side wallsof thecasing 4 are U-shaped depressions ci, said depressions serving as bearings for the trunnions 7, 7 of an oscillating frame or yoke 8 spanning the casings 1 and 4, the outer cross member of the yoke being formed with a finger hold or lip 9 by which thesame may be manipulated. The inner ends of the trunnions are formed with arms oroffsets 10 which are in turn connected by a cam member 11, the general appearance of the parts 7, 10, 11, resembling a double crank shaft, the parts 10 corresponding to the crank arms andthe part 11 to the crank pin. The cross-section of the cam is substantially as shown ,in Fig. 4, the same having a decided nose or protuberance n at the point of maximum sweep of the cam, the purpose of which will presently appear.

Mounted slidably and .reciprocably in the casing 4 is the bolt 12 the sides of which are provided with guides or runners 13, 13, eX- tending a suitable distance beyond the rear edge ofthe bolt, one of the runners terminating at the rearend in a foot 14 of the same width as the runner, the corresponding end of the opposite runner terminating in a foot 14 extending laterally and inwardly and forming an offset or shoulder t with the inner face of the runner. The inner edge of the bolt 12 is formed with a central lug 15, the feet 14, 14', being spaced sufficiently from the free end of the lug 15 to accommodate between them the trunnions 7, 7, with their offsets 10, 10, and connecting cam 11. In other words, when the trunnions 7 ofthe yoke 8 are deposited in their depressions or bearings (Z, and the bolt 12 with its runners is properly placed in the casing 4, the yoke is free to oscillate about the common axis of the trunnions 7, 7, the cam 11 engaging the lug 15 and forcing the bolt outwardly or into the keeper 1 with a downward or forward throw or oscillation of the yoke; and engaging the shoulder t of the foot 14 and forcing the bolt inwardly or ico out of the keeper with a complete upward or. rearward throw of the yoke. In Fig. 4 the yoke is shown dotted at the middle of its stroke (upward or downward). Formed in the roof of the casing 4 is a slight depression 71, in which is secured one end of a fiexed spring 16, the free end of which constantly bears and rides over the surface of the cam 11, the purpose of the spring being to hold the yoke S locked when it reaches the end of either of its strokes or throws. Thus, in F ig. 4 the spring bears against the concave side of the cam to one side of the rotation axis of the trunnions 7 7, the pressure exerted by the spring on the cam holding the yoke to its locking position. wWhen the yoke is swung one hundred and eighty (180) degrees to the left the spring will obviously bear against the diametrically opposite face of the cam and hold the yoke to its unlocking or releasing position, the depression 71. accommodating the spring when the nose a of the cam forces it against the roof of the casing 4. The nose amay be considered as the most active part of the cam, the saine rubbing against the end of the lug 15 of the bolt with a forward or locking stroke of the yoke thereby driving the bolt across the seam vl between the plates 5 and 3 well into or-under the keeper 1, the said nose rubbing against the shoulder t of the foot 14 of the runner 13 with a rearward or releasing stroke of the yoke, and thereby forcing the bolt away from the keeper 1 and permitting the lid L to be swung open after the lock A is unlocked. The casing 4 is preferably provided with a cross-strip 17 projecting inwardly along the free edge ofthe roof thereof, said strip being of a length to freely admit the runners 13 between the ends of the strip and Vthe inner faces of the side walls of the casing, but being of suficient length to foul the shoulder t of the foot 14', thereby preventing the bolt from dropping out of the casing with an assembling of the parts. This strip 17 is however not indispensable. The fixed end of the spring 1G terminates at this strip. The feet 14, 14 obviously serve to guide the bolt, bearing as they do on the plate 5 to which the casing 4 is secured, said feet being disposed at right angles to the runners 13, that is to say, at right angles to the plane of movement of the bolt. Obvi: ously, I may change the construction in many particulars without departing from the nature or spirit of the invention. Again, the valance Z) herein shown` as secured to the trunk section T may be shifted to the trunk section T. Likewise may the positions of the members 4 and 1 of the fastener be reversed, that is to say the keeper 1 may be on the trunk section T and the casing 4 may be placed on the lid L. The fastener is of course not limited in its application to trunks or trunk lids but may be used in any art wherever the same is applicable.

Having described my invention what I claim is:

1. In a fastener of the character described, a casing, a'sliding bolt in the casing, an

oscillating member operable from a point outside the casing, a cam on the member disposed about the axis of oscillation of the member, and suitable formations on the bolt engaging the cam on opposite sides of said axis, whereby the bolt may be actuated in either direction depending on the direction of throw of the oscillating member.

2. In a lid fastener of the character described, a casing open at one end, a keeper cooperating therewith and forming an extension thereof with a bringing together of the parts, an oscillating yoke spanning the casing and provided with a pair of trunnions mounted rotatably in the side walls of the casing, a central cam connected to the trunnions and offset from the axis of the trunnions, a sliding bolt in the casing, guide members or runners carried by the bolt and extending beyond the inner edge of the same, a lug projecting inwardly from said edge, feet projecting at an angle from the inner free ends of the runners, one of the feet being formed with an offset facing the opposite runner, said feet being spaced from the lug sufficiently to admit the cam of the yoke between them and the lug, the cam being provided with a formation bearing against the lug of the bolt with a sweep of theyoke in one direction to drive the bolt toward the keeper, and bearing `against the offset aforesaid to drive the bolt away from the keeper with a sweep of the yoke in the opposite direction.

3. In a lid fastener of the character described, a bolt-actuating yoke comprising an open frame having `trunnions vat one end thereof directed inwardly toward the axis of the yoke, offsets or arms leading from the trunnions at an angle to the axis of the trunnions, a cam connecting the sweep endsof the offsets, and a sliding bolt having formations coperating with the cam for driving the bolt first in one direction and then the other dependingon the direction of throw of the yoke. .i .f
