TRUNK LOCK.

Application filed July 7,1923. Serial No. 65(1188.

To all whom it may concern:

Be it known that I, MARTIN RASMUSSEN, a citizen of the United States, and resident of Racine, in the county of Racine and State of Wisconsin, have invented new and useful Improvements in Trunk Locks, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to trunk locks, and has for one of its objects to provide a lock which is particularly adapted for use with wardrobe trunks.

A further object of the invention is to provide. a lock which is especially adapted for interlocking the wardrobe and drawer sections of a wardrobe trunk.

A still further object of the invention is to provide a lock of the character described which may be semi-automatically operated by the movements of the top cover section of the trunk. i

A still further object of the invention is to provide a lock of the class described which is adapted to engage with a keeper carried by one of the said sections before the sections are completely closed, and to positively draw such section to its fully closed position, and tothere positively lock the same.

A still further object of the invention is to provide a lock of the character last described in which an increased leverage is obtained as the drawing action progresses. A still further object of the invention is to provide a lock of the class described which will be simple in construction, comparatively inexpensive .to manufacture and install and more efficient in operation than those which have been heretofore proposed. With the above and other objects in view which will appear as the description procoeds, the invention consists in the novel details of construction and combinations of ")fl ltfi more fully hereinafter described and particularly pointed out in the appended claims.

Referring to the accompanying drawings in which like reference characters designate like parts in all the views;

Figure 1 is an elevational view of a wardrobe trunk, the three sections being shown in their open positions and providedwith a lock constructed in accordance with the present invention;

F g- 218 a f gm t ry inside elevational view on a larger scale, of a wardrobe sectlon, showlng a lock constructed in accordance with the present lnventlon in place thereon Fig. 3 is a view similar to Fig. 2, showing the lock in its closed position; and,

4 is an edge elevational view of the lock asseen from the left of Fig.2.

Referring more particularly to the said drawings the numeral 5 indicates the wardrobe section of a wardrobe trunk, 6, the drawer section thereof, which may be hinged to the. wardrobe section in the usual well known manner, and 7, the usual top cover section also hinged to the wardrobesection, and adapted to close the normally open end 8 of the said wardrobe section.

-The said top cover section 7 may be provided withv a hasp member 9, pro-vided with.

a suitable Yale or other key lock 10, adaptt ed to co-operate with the lock receiving member 11, carried by the upper portionof the drawer section 6, when "the parts are in closed position, as will be readily understood.

The said drawer section 6 is provided with an escutcheon plate 12, which has rigid therewith a keeper lug or member 13 and the wardrobe section 5 carries the lock assembly 14, suitably positioned thereon'to co-operate with the said keeper member 13, as will presently appear. The said lock assembly preferably comprises a casing 15, adapted to be fitted within a recess 16, provided in the wall of the wardrobe section, which casing includes a pair of transversely extending guide plates 17 fitted adjacent the edges of the said recess 16.

slidably mounted between the said guide members 17 is a reciprocating member 18, which pivotally carries a pair of keeper engaging'dogs or members 19, provided on 7 their outer ends with the keeper engaging toes 20, as will be readily understood from Figs. 2 and 3 of the drawings. The said members 19 are also provided with 'shouL ders 21, provided with inclined cam surfaces adapted to engage and eo-opera'te with the guide members 17 to force the said keeper engaging members 19 inwardly about their pivots 22 when the slide. member 18 is moved to the right, as viewed in Fig; 2, thereby causing the said keeper engaging members 19 to engage the keeper member or lug 13, as will be readily understood.

The said members 19 are also provided with the projections 23, adjacent their pivot members 22, which are adapted to engage and co-act with a lug 24 carried by the casing to move. the said members. 19 to their open positions when the slide member 18 occupies the position illustratedin Fig mQ.

The slide member 18 is preferably provided with an elongated apertrrre; 35, one end of which is provided with suitable rack teeth, adapted to be engaged by the teetlr of a gear or pinion 27, which'is rotatably mounted on the shaft 28 of the said casing or housing 15. One end of the said shaft 28' is squared as indicated 2113-29, and rigidly carries the arm 30', which is provided with an elongated slot or opening 31,- which receives a pin 32', carried by the lower end of the Beck operating rod This said rod 33- is slidabl y mounted in straps 34, se-

cured to the side wall of the wardrobe sec-' from the foregoing, but it may be briefly summarized as follows:

The parts being in the position illustrated in Fig. 1 and it is desired to close and lock the sections, the section 6 is swungupon its hinges toward the section: 5' 1n the well known manner, until the keeper memberor' lug 13 passes between the spaced ends 01 the keeper engaging members 19. The top cover section 7 being new swung downwardily' to close the open top 8 of the wardrobe section 5, its plate or member 37 will engage the head 36 017 the rod and will force the said rod downwardly. This downward movement will be connnunicatedi through the pin and slot connection, and '32, to thearnr shaft 28, pinion 27, and

from the said pinion through the rack teeth 26 to the slotted member 18', which will be moved from its position shown in Fig. to that indicated in 3.

This movement 01 the slide member 18,

with, o f course, carry with it the pivoted keeper engaging members 1 9, the shoulders 21 of which will co-act as cams with the guide member 1 7 to force: the said members 19 toward eaclr otheig tl iereby causing their" shouitlers 20 to engage the keeper member 13; Further movement of the slide member' 18 with the keeper engaging member- 19* such closed position"- will cause the keeper member 13 and: t'l' ie entiredrawer:

section 6- to be positively drawn to the tully closed positions of the sections in which po sition they will be securely locked, due to the fact that reverse movement of the parts may only be effected when the top cover section 7 has been lifted to permit the rod to rise. It will be understood of course, that when the trunk is closed the 100K 10, carried by the hasp 9 of the top cover sec-. tion, will be engaged with its keeper member 11 carried by the drawer section, all three sections thus securely interlocked.

Utenit is desired to open the trunk the lock 1 0 is first unlocked by the use ofa key, or in any other well known manner,- and the top cover: sectionraised to its position ii l 'ustrated in Fig. 1 This will release the rod whereupon the coiled springs will force the slide member 18 toward the left, as viewed in F until the projections 23 of the keeper engaging members 19 contactqwith the lug 2 1-, which contact will have the effect e l spreading the keeper engaging members ld to the positions shown in Fig; 2, thereby permitting the keeper member 13- to be withdrawn as the drawer section 6 is swun'g' outwardly.

It will be noted? that at thestartof the locking operation the pin 32' of the rod: 33 is at the end? of the slot 31% nearest to the shatt 28, see Fig. 2;. However, as; the rod 33 moves downwardly the said. pin. moves outwardly through. the said? slot 31 to the end thereof tarthest iironr the: shaft 28,. thereby securing an increased leverage as the locking: operation progresses.

Whiie one form oi the invention has been illustrated and described it is obvious that those skilled in the art may vary the details of construction as well as the arrange me-nt of parts without departing from the spirit. of the invention, and? therefore it is not wished' to beylimited to the above disclosure" except as may be required by the acconrp anylng claims.
