SPECIFICATION forming part of Letters Patent No. 285,916, dated October 2, 1883.

Application filed May 21, 1883. (Model.) 4

To @ZZ whom t may concern:

Be it known that I, FRANK XV. MIX, a citizen ofthe United States, residing at New Britain, in the county of Hartford and State of 5 Connecticut, have invented certain new and useful Improvements in lrunk-Locks, ofwhi ch the following is a specification.

My invention relates to improvements in trnnk-loeks of theclass which are known as hasp-locks#7 and the objects of my invention are to simplify the construction of the parts, to

make a device which will not only lock the trunk, but which will firmly connect the trunk cover and body, and to provide a iock which, i 5 although simple in construction-and inexpensive to make, will be very durable andefficient. I attain these objects by the construction illustrated in the accompanying drawings, in

which- 2o Figure l is a front elevation of my improved lock, with the parts slightly separated from each other and represented as unlocked. Fig.

'2 is a side elevation of the saine. Fig. 3 is a rear elevation of one part of my trunk-lock,

the saine being represented with the paris in position for locking. Fig. 4 is a central vertical section online x x ot' Fig. l, but with the parts represented as brought into engagement and locked. Fig. 5 is a transverse section of the lower part of my lock, the plane of section being indicated by line y g/ ofFigxAl. Fig. (i is a front elevation of my lock, with the parts represented in the same position as in Fig. l, but with a slight modification in the engaging parts of the hasp and the keeper.

Fig. 7 is a central vertical section of the keeper and upper end of the hasp, the saine being represented as engaged with each other, as shown in Fig. 6. Fig. 8 is a front elevation of 4o another style of my improved trunk-lock, the parts being represented as unlocked and slightly separated. Fig. 9 is a plan view of the lower member of sa-id lock, with the upper end of the hasp represented in section upon line e z of Fig. 8. Fig. l0 is a front elevation of another style of my improved trunk-lock, a portion of its hasp being broken away upon one side in order to show the part-s behind it, the parts 0f this fastener being represented as 5o unlocked. Fig. 'il is a horizontal section,

with the parts represented as brought into engagement and locked, the plane of section being indicated by the line w w of Fig. l0.

A designates the keeper, which is adapted to be secured to the front of the trunk-cover, and is provided with a dowel-pin, n., immediately above which is the projection b, for the upper end of the hasp to hook over.

c designates a raised ledge, which projects from the front of the keeper-plate A and surrounds the upper end of the hasp to protect it, and also form a better iinish to the article.

B designates t-he hasp plate or frame, which is designed to be secured to the front of the trunk-body, and it has hinged to it the spring- 6 5 pressed hasp C, whose upper end is perforated i o1: provided with an eye for engaging the upper side ofthe projection I) upon the keeperplate A. At the upper end of this plate B is a bridge or cross-piece, d, which hasan open space upon the back side to form a socket for the dowel-pin a. Said bridge d also forms the staple or keeper for the lock-bolt c.

Upon the front of the plate or frame B, I form two outwardly-projeeting ribs, f, which lentend longitudinally with said plate for nearly its whole length, and in between which ribs the hasp C shuts closely, so that said hasp is protected from lateral vibration for nearly its whole length. This frame is provided with a 8O rectangular opening through it, as shown by the rear view, Fig. 3, and by the side of said opening, near the lower end, I form trunnionrecesses g, which are mere open recesses and are formed in the act of casting. l 8 5 A little above the lower end of the hasp C trunnions 71 hare formed, which iit into the recesses g g. (See Fig. S.) The body of the hasp C is cast in box form, so as to form acase for the lock. The lock-bolt e, adapted to be thrown by means of akey, (its lock mechanism being of ordinary construetion,) is placed within this lock-case or hasp, and is covered by the cap-plate D upon its back side, as shown in Figs. 3 and 4. After the lock is 95 properly secured to the under side of the hasp C, the hasp is slipped endwise through the opening in the frame B, and then the trunnions h are dropped into the recesses g, and the hasp is secured in place by mea-ns oi" the spring 7c.V roo The end of this spring is curved, so that it has a constant tendency to throw the hasp outward into the position represented in Figs. 1 and 2. The lower end of the hasp, which projects below the trunnions h h,strikes against the back side of this spring when the lhasp is opened, and limits the outward motion of said hasp. This spring is of sufficient strength to thus act a's a stop for the hasp, to hold the hasp within its bearings during transportation; but when the parts are once secured to the front of' the trunk-body, the spring is supported and. backed by said f'ront, so thata light spring is sufficient for all practical purposes. The space or opening in the lower part of the `bridge or stapled is smaller than it is at the upper part,

and the rear side of t-he dowel-pin a., which depends from the keeper-plate A, is recessed or cut away, so as to allow the lock-bolt to pass upward behind a part of the dowel-pin,

as shown in Fig. 4.

NVhen the parts are secured upon a trunk in the manner hereinbefore suggested, and the trunkcover is brought down, the dowelpin a enters the month of' its socket and brings the plates A and B into proper position for engagement of the parts for locking. The dowelpin and socket also prevent the trunk from racking, and thereby causing a strain upon the working partsof the lock. After the trunkfcover has been brought down so as to bring the dowel-pin and socket into engagement, the hasp C is depressed against the power of its spring, so as to bring its upper end into enl gagelnent with the projection b, to hold the trunk down, when by the application of the proper key the lock-bolt .e is thrown into the l position represented in Fig., 4, so as to hold the hasp into engagement with the projection b of the keeper.

, hasp is protected by the flangcsff for nearly its whole lengthso as to make a very firm fastening. The dowel-pin and socket also prevent an undue lateral strain frombein g brought upon this hasp, while at the same time this dowel-pin does not enter the lock proper.

The lock-bolt, instead of being made to take hold of the dowel-pin, merelyengages with the lower side of the bridge d and prevents the hasp from swinging outward, so as to liberate its upper end from the projection b, thus `making avery secure, cheap, and simple lock, so arranged as not to be liable to injury from the usual racking strain and severe usage to which trunks are subjected. Y

The parts represented in Figs. 6 and 7 are the same as those hereinbefore described, with the exceptionthat the keeper is provided with an eyeor opening, and the projection b,:which engages therewith, is formed upon the upper end of the hasp G. All of the other parts in said figures are lettered the same .21s in Figs. 1, 2,-3,'4, and 5. In Figs. 8 and 9 I have represented a lock Yin which the keeper-plate A has three dowelpins, a. Said keeper-plate is also provided \Vhen in this position thev ment with sai d dowelpin.

with the locking projection b for engagement with a recess upon the back side of' the upper end of the hasp C". This hasp Gis secured to the plate or frame B and is thrown outward by a spring; but instead of having the lock secured to the hasp, the hasp is inthe form ofV a frame, and the lock D is secured to the plate B. -This plateB is also provided with' three sockets at its upper end for engagement with .the dowel -pins a', and the hasp is provided with a staple, d', at a point just above the upper end of the lock D. Afterthe parts are brought j into engagement, as before described, and the hasp pressed inward, so as to engage its upper end with the projection b, the lock-bolt e', by the application of' a proper key, is thrown upward and into the staple d, thereby holding the hasp into engagement `-with`the projection b of the keeper A', substantially in the manner 'of the lock herein first described.

\ The lock shown in Figs. 10 and l1 is changed from that shown in the other figures by what may be termed a revers. l or inversion 7 of' the parts. In this lock I intend to apply the keeper-plate E to the front of the trunk-cover. I hinge to the hasp-plate F the hasp G, which is made inloop form, and whichis also pressed outward by means of a spring, as in the other figures. The lower end of this hasp I provide with a loop or staple, m, for engagement wit-h the lock-bolt u. I also provide the lower edge 'of the hasp-plate F with three dowel-pins, o,

and the upper part of the plate E is provided with corresponding sockets to receive said` roo K dowel-pi ns. The middle one of' these sockets is formed in the back side of' the locking projection p, as indicated by the broken lines in Fig. l0. Upon the front of the lower part ot' the plate E, I securethe lock I-I, which may be of' any ordinary construction. After closing the trunk, so as to bring the parts into proper engagement, the lower end of the hasp Gis depressed, so as to bring its staple m directly in front of' the loek-bolt n, after which the lock-bolt may be thrown into the staple, as

shown in lFigli., and thereby 'firmly secure the hasp in its locking position, with its loopshaped lower end engaged with the projection p.

I am aware that trunk-locks have been heretofore provided with a dowel-pin and socket, when the dowel-pin entered a part of the lock and when it was secured thereto by having the lock-bolt brought into locking engage- Such a combination of a dowel-pin and lock I hereby dis- 1f In a trunk-lock, the combination of the K hasp-plate, the hasp hinged thereto, the spri ng arranged to press upon the hasp, with a con-` stant tendency to throw it outward, the keep- `hasp C, bearing a look upon its rear side and trunnions g near its lower end, the frame or plate B, having an opening therein through which to insert the hasp C, and having trunni on -reeesses upon its rear face, andthe spring 71:, for holding the hasp Within the recess, throw-r ing the hasp outward,and for acting as a stop, substantially as described, and for the purpose specied.

4. In a trunk-lock, the combination of the plate A, having the doWel-pin a, the plate or frame B, having the bridge d, and the swinging hasp C, bearing the look and look-bolt e, the parts being combined so that the doWel-pin and plate both engage the bridge 11 subst-antially as described, and for the purpose speciiied.

5. ln a trunk-lock, the combination of 'the hasp -plate, the hasp hinged to said hasp-plate, the keeper-plate, the loek-bolt for locking the hasp into engagement with the keeper, and the doWel-pin and socket at the meeting edges of said two plates, all combined substantially as described, and for. the purpose specified.
