SEAL AND KNOT PROTECTOR.

Application filed April 5, 1924. Serial No. 704,319.

Z '0 all whom it may concern: 1

Be it known that I, SAMUEL BARUGH, a

citizen of the United States, and resident of the city of New York, borough of Manhat tan, in the county of New York and State of New York, have invented certain new and l useful-Improvements in Seal and Knot Protectors, of which the following is a specification.

The present invention relates to improvementsin seal and knot protectors of the general character disclosed in my Patent No. 1,074,7 69 of October 7 1913, in which two telescoping inter-locking members provide a chamber or cavity adapted to receive and protect the knotted or united ends of a cord or wire; a guard member adapted to prevent the insertion of an instrument for effecting dis engagement of the two locking members.

In the device of said patent the bead which connects thetwo sections of one member 1s on the outside where a skilledmechanic pro vided with the proper type of tools might after considerable very careful efi'ort succeed in raising the bead,.reducing the diameter thereof and separating the parts without mutilating the same sufficiently to attract the attention of an ordinary user. Thereafter he might reassemble the parts.

It is an object ofthe present invention to "overcome this possible objection by so designing the parts that the head is within the knot chamberwhereaccess cannot be gainedthereto and I thereby effectively preventthe unauthorized disassembly and reassemblyof the device.

With-my improved device the guard section constitutes a wall of the knot receiving chamber and entirely encloses and conceals one of the interlocking sections and their seam or joint is on the inside instead of on- Fig. 3 is a similar view through the locking section of the other member; and

Fig. 4 is a similar view through the guard section prior to the assembly of the guard section and the locking section with which it is permanently associated.

The patented device also included improved knot protector comprises two inter-engaging or interlocking members 10 and 11, the member 11 being :formed of two sections, '12 and: 13, permanently connected together. The section 12 interlocks with themember 10 and the section 13 constitutes a guard which effectively prevents the insertion-of a tool to effect disengagement of the section 12 with the interlocking member: 10. All. three of the sections are formed of stamped, spun or otherwise fash ioned sheet metal, the character and gauge of which is dependent upon the use for which the completeddevice is designed.

The .member 10 is substantially cup shapechincluding an end wall ltand a peripheral wall 15. At the open end of the cup the peripheral wall 15 is provided with an inwardly and backwardly turned flange 16 adapted for interengagement with a flangeformed on the section 12 of the mem- 1 her 1 1. The section 1.2 is substantially ring shaped and of appreciably less diameter than the cup shaped member 10.. A flange 17 is turned outwardly and backwardlyfrom one edge of the ring shaped member 11 and is a preferably concavely curved, lying substantially flat "against the-outside of the ring adjacentto its point of union with the ring and flaring outwardly therefrom at its free edge. One of these flanges preferably the flange 17 is 1 sub-divided into; a. series of spring fingers. The member 11 at its other edge is formed withan inwardlyj turned annular flange or lip 18 adapted to be engaged by the guard 13.

The guard section 13 of the member is substantially cup "shaped and relatively shallow. It included an end wall 19. anda vnarrow peripheral wall 20' adapted to encircle and embrace the free edge of the peripheral wall 15 of the member 10, when the members 10 and 11 are assembled. f The end wall 19 has a central circular depression 21 of approximately the-same diameter as the 13 and the section 12, the depressed portion 21 of the guard section is spun,.swaged or stamped to flatten it and form a bead and a aperture in the end of the section 12. To"- effect a permanent connection of the guard groove 22.. The latter receives the flange and the forming of the bead firmly clamps the flange between the two walls of the groove.

The centralportion of one of the sections,

as for instance the portion 21 of the guard,

is formed with one or more openings 25 through which maybe passedthef ends of a cord or wire 26 wrapped about a package 27, or passed through any part to be sealed construction is the forming of the bead onthe inside'instead of the outside of the knot chamber sothat the prying up ofthe bead is impossible. I 7 tively rotated *but such rotation is without e'flect'in so far as their continued inter-en- I gagement is concerned." Pressure exerted i'directly' upon the central section 21 ofthe guardseetion will not result in restoring this member tothe shape shown in' Fig. 4. It

will merely result in rupturing the guard two telescoping members, inter-engaging section. The only way in which the guard "section and locking sectionof; the member 11 "can be separated without permanently mu ti la'tingthem' is to exert pressure on the bead oi "the guard section which co-operates with the main body'thereof to form the groove 22. When the "two interlocking members are 'assembled,'however, access cannot be had to the interior of the knot receiving chamber for this purpose. a

It will be obvious that certain changes and 'alterationsniightbe made in the general form and arrangement of the parts'described without departing from the spirit of the invention, or the scopeoi the appended cl'aims.- V

' What I claim 1 as new and desire to secure by Letters Patent is: 1 V

1'1. A'seal'undfknot protector comprising a pair of inter-engag-ing'members forming a knot receiving chamber, one of said members including'a locking section and a guard section permanently connected together, said guard section constituting a wall of the knot receiving chamber, said locking section being of general ri-ng shape and including an internal flange permanently connected to the guard section.

2. Aseal and knot protector comprising a pair of inter-engaging members co-op'erati-ng 'to'form' a knot receiving chamber, one of said members including a ring shaped lock- 'ing section and 1a guard section, said lockingsection having an internal flange'permanently secured to said guard section.

3. Aseal and .knot iprote'ctor comprising a pair of inter-engaging members telescoping to form a knot receiving chamber, one of The two members maybe relasaid members including a ring shaped locking section and a guard section, said locking section having an internal flange and said guard section being formed with an outwardly opening annular groove receivlng said flange.

4-. A knot protector comprising a pair of interlocking members telescoping to form a knot receiving-chamber, one of said members including an annular locking section anda guard section including an offset central portion extending inwardly and permanently secured to the annular locking section '5. A seal and knot protector comprising two telescoping members, inter-engaging locking devices carried by the members-and means concealingthe inter-engaging locking devices. comprising a guard section permanently attached to the interior of one of the telescoping members. s T
