ROPE LOCK FOR TRUNKS, CRATES, AND THE LIKE.

Specification of Letters Patent.

Patented'Feb. 24, 1914.

Application filed March 24. 1913. Serial No. 756,551.

To all whom it may concern Be it known that I, JOHN J. A. MILLER, a citizen of the United States of America, residing in the city and county of Denver and. State of Colorado, have invented a new and useful Rope-Lock for Trunks, Crates, and the like, of which the following is a specification.

My invention relates to improvements in trunk and box and package holding and locking ropes, and the objects of my invention are: To provide a fastening rope for trunks, crates and the like, to one end of which is secured an improved locking device, by which the rope may be securely clamped and held after being drawn around the sides and ends of the trunk or crate in the usual manner. trunk fastening ropes, comprising a casing having a grooved pulley and a friction clamp adjacent thereto, a rope being fastened in one side of said casing, adapted to be passed around the trunk and into the opposite side of the casing, and out through the adjacent end of the casing, whence it is looped around the trunk at right angles to the first loop, and passed over and around the said pulley, and is held under tension by the friction clamp, which holds the rope between itself and the pulley so as to prevent accidental loosening of the same. v l

I attain these objects by the mechanism illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a trunk showing the same secured by a rope having an improved locking device which forms the subject of the present invention. Fig. 2 is a front view of the lock. Fig. 3 is a central longitudinal sectional view of the same. Fig. 4 is a front view of the lock with the cover removed, and showing the manner in which the rope is clamped and held, after being drawn around the trunk, as shown in Fig. 1. Fig. 5 is a side view of the lock, with the rope clamp removed, and showing the corner folded back in dotted lines. And Fig. 6 is a perspective view of the locking wedge.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings,The numeral 1 designates the lock portion of my trunk, box and package holding and locking rope. This lock portion comprises a casing 3,

Further, to provide a lock for which is which'consists of a back 4, side portions 5 and end portions 6 and 7, each of which, as well as each side, is provided with a projecting lug 8. The back 4 and sides 5 and the two ends 6 and 7 are stamped out in the form of a fiat blank from sheet iron or other suitable metal and then the ends and sides are bent up at right angles to the back. A round pin 9 projects from the inside of the back portion of the back, to whichit is secured and projectsto the top of the sides of thefcasing, and a pulley 10 is mounted rotatively on this pin, which is provided with an enlarged head portion 11,-that holds the pulley on the pin9. The'face of thispulley is concaved to receive a rope andits surface is preferably serratedor knurled to cause the rope to cling to it without slipping thereon, as easily as it would if the face of the pulley was smooth. 'Inone side of the end of the lock, an aperture 13 is formed in which one end of a rope 14, extends, the end of which is tied into a knot 15, which rests insideof the end-and against the inside wall of the lock..- This rope l4is made of any predetermined lengthland it is looped and its opposite end. ispassed through two apertures 16 and '17, on the opposite side of the end 12 of the lock. Between the'pulley and the tail end-18 of the lock a flat pin 19. is formed on the back of the lock and projects therefrom to close to the top edges of the adjacent sides of the lock. This pin forms an abutment for a keeper 21, which forces the rope against its edge as will be presently described. On the open'side of the look I place acover 24. This cover may be mounted on the lock. and be secured thereto if desired, in any suitable manner. I preferably, however, hinge one end oft-he cover to the edge of thehousing that covers the knotted end of the rope and arrange the cover with an overhanging lip 25 which extends over andfits tight enough. closely on the sides of the lock and is secured in place by a lug '26 which is out free from the cover and extends down andiscurved to engage a curved end portion formed on the end of the abutment lug 19, with a sliding and springing fit as the two curved portions engage and the one on, the cover slides on and over the other,

thus forming a spring catch.

The keeper 21 comprises a sliding rope key wedge that is positioned along the inside edge of one side of the lock, and a hand grasping end portion 29 at one end of the key that is bent at substantially right an gles to the rope key and extends through and beyond the side of the lock. The oppositeiend portion of the, keeper is reduced to 5 a neck portion 31, and is bent to one side and extends through an oblong slot 32, in which it is slidably mounted and the terminal'end portion of this end of-the rope key is provided with an enlarged head portion 34, which bears on the outside ofthe adjacent side of the-lock and secures the key slidably in the slot 32 and in the lock. The rope engaging" surface of the key is serrated orotherwise knurled to enable it to grip into the rope. This rope key is slidably mounted opposite to one side of the pulley in such a position that its heel portion85 can be moved inwardly toward the pulley and then slidtoward the pulley and grip in a decreasing wedge-like space the rope both between the pulley and the adjacent edge of the flat spring pin, thus securing -it against slipping backward after it has beentightened around a trunk or box or-a package. ,7 v a r h The operation is as follows: The rope is looped around a trunk or box. or a package and then the cover of thelock isthrown I 1 back'and'the end of the rope is passedin the open side 36 of the lockaround the pulley and then between the pulley and the wedge key and the fixed fiat pin and then the free end ofthe rope is" drawn tight as theoperator can pull it aroundthepulley, then :before the operator releases the rope he grasps the fingergrasping portion of the wedge key with one hand and forces the wedge key against the rope, jamming the rope against the edge of the flat pin and at the same time that he releases the pull on the rope'he pushes the wedge toward the pulley, thus wedging'the rope between the edge of the pin and also the sideof the pulley, and securing it in a tightened position against accidental. slipping movement and loosening of the rope. 7 7 lVhile I have preferably illustrated a rope as thetrunk or other tying member, my invention contemplates the use of a strap also.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is v 1; In a device as specified, the combination of a easing .a pulley therein'and a manually sliding rope wed ing key, an abutment pin mountedin said casing adjacent to said pulley, with a rope secured-at one [end to said casing and arranged to be placed around said pulley and alongside of said fixed pin, and arranged and adapted to be wedged against said abutment pin and said pulley and to be locked thereto against accidental loosening movement.

2. In a device as specified, the combination of a lock casing having a rope secured at one end to one corner of one end of said lock, said casing being provided at the opposite corner of its end where one end of said rope is secured, with a pair of apertures through which the free end of said rope is extended, a pulley in said casing and a fixed pin, with a rope keying wedge comprisin a thin strip of metal having one end slidabIy mounted in said casing, and a finger grasplng portion at its opposite end,

said rope keying wedge being secured to said casing, and arranged to be moved at its finger grasping end toward said fixed pin and pu ley and to stand at a wedging angle thereto and to engage a rope placed between said key and said pulley and said fixed pin and then to be moved toward said pulley to wedge said rope between it and said pin and pulley, and a suitable cover hinged to said casing.

3. In a trunk tying rope lock, the combination with a rope, of a lock comprising a casing having a back and side portions, said rope being secured at one end to one corner of said lock, the said same end of said lock to which said .rope is secured being provided with a pair of apertures spaced a short distance apart, arranged to receive said rope and through which said rope extends thereby forming a loop of rope, said rope having its free end extending from said apertures, a pulley mounted in said casing at a short distance from the end of said lock where said ropes are secured, a fixed pin in said look at a short distance from said pulley, past which said rope extends, and a manually operated wedge shaped key slidably mounted in said lock adjacent to one side of'said pulley and said fixed pin and arranged and adapted to be moved to wedgingly clamp said rope against the adjacent side of said fixed pin and the adjacent side of said pulley, and a cover arranged to house said pulley and rope locking key in said casing.

y In testimony whereof I afiix my signature in presence of two witnesses.
