PATENT OFFICE ASSIGNOR TO THE INTERNATIONAIJ SEAL & Know ifno'rno'ron (10., on NEWHYORK, N. Y., A CORPORATION OF EW Yonn" sEAL;
Refiled for abandoned application Serial No. 318,475, filed NovemberlO, 1928. This application filed January 11, 1932.
This application is a substitute for applicants prior abandoned application, Serial No. 318,475, filed November 10, 1928. This invention relates to meansfor sealing the ends of a string, cord, or small wire to prevent the separation of the ends. The character of the device which is held by such a string, cord or wire (hereinafter referred to as a cord) is not material in this case. It is common practice to attach tags to various devices and to seal the ends of the cord u hich connect the tag to the article so that the tag cannot be removed.
In many industries it is important that the seal be of such a character that it may be very easily applied and of such design that it may be made at very slight expense.
The main object of my invention is to provide a sealing device in which the movable parts are permanently connected so that the user does not have to assemble them at the time they are applied.
A further object is to provide a simple design which may be made by the minimum number of stamping operations.
A further object is to provide a device which may be sealed without the need for any special tools or appliances.
In the accompanying drawing I have illustrated merely one embodiment of my invention. It will be apparent that various changes may be made within the scope of the appended claims without departing from the spirit of my invention.
In the drawing:
Fi 1 is a perspective view of the device in clb sed position; Fig. 2 is a top plan View; Fig. 3 is a central longitudinal section on the line 33 of Fig. 2;
Fig. 4 is a view showing the outer or casing member in open position, but showing the inner member in closed or locked position; 7 Fig. 5 is a central longitudinal section on the line 55 of Fig. 4E, and Fig. 6 is a perspective view of the inner member.
In my improved construction I provide an open-ended casing with a slide movable longitudinally thereof. The parts are so designed Serial No. 585,971.
that the slide cannot be removed from the casing and has limited longitudinal movement. The parts are also so designed that when the slide is moved inwardly to its innermost position it is locked against return movement and will look a loop of the cord inside of the easing.
In the specific form illustrated the casing is formed of a single piece of sheet metal having two plate portions 10 and 11 connected by a neck'12. The plate portion 10 has comparatively narrow upstanding sidev flanges 13, while the plate portion 11 is slightly larger and has higher side flanges 14. 7
To form the casing the neck portion 12 is bent until the plate portions 10 and 11 are in superposed parallel relationship and spaced by the flanges13. The flanges 14 which extend below or beyond the plate 10 are then folded over onto the outer surface of the plate as shown in Figs. 1 and 2. The neck thus forms one end of the casing, while the other end is open.
Within the casing there is provided a slide 15 whichis of a width substantially equal to the openend of the casing. The flanges 13 and 14 curve inwardly at the open end of the casing so that the body of the casing is wider than the open end. The slide 15 has a head 16 wider than the body portion and this is provided with a pair of resilient tongues 17. In the flanges or inner side walls 13 I provide short slots or notches and the portions adjacent to said notches are bent inwardly to form resilient tongues 18. The outer end of the slideis provided with a lateral flange or thumbpiecev 19. The slide 15 also has a notch 20 in one side thereof and which is preferably a V notch with the inner end inclined toward the thumb piece. L
In assembling the two parts of the device the slide is placed in the casing, but not in the position shownin Fig. 4. It is placed wise through a limited distance and to permit the notch 20 to come outside of the open end of the casing. The two plates 10 and 11 of the casing are then bent to parallel position and the parts locked together by bending over the edges of the flange 14: as shown in Figs. 1 and 2.
In using the device the slide 15 is pulled out until the notch 20 is outside of the casing. The two ends of the cord are then laid in the notch and the slide is forced inendwise until the tongues 17 snap past the tongues 18, and interlock therewith as shown in Fig. 4-. The two lengths of cord will thus extend into the casing along one surface of the slide through the notch 20 and back out the open end of the. casing at the other side of the slide. It will be noted that the cords turn a sharp angle in the notch 20. Thus any pulling of either end of either cord will draw the cords down into the V of the notch where they will wedge in place, and neither cord can be pulled out by pulling upon either end.
It will be evident that the device might be opened by prying up the side edges of the flanges 14, but to avoid this the parts are'made of comparatively brittle metal so that they will not stand much bending, and in any event they are made very small so that any tampering with the seal would leave telltale evidence unless extreme caution be employed. For the purposes for which this seal is primarily intended the opening of the seal is very diflicult and adequately serves its purpose.
The resilient flanges 17 and 18 cannot be tampered with as they are concealed and protected by the side walls or flanges 14.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A seal including a casing formed of a single piece of metal including two plate portions and a connecting wall, said plate portions being in superposed spaced relationship and the connecting wall forming one end of the casing, one of said plate portions having side flanges for spacing the plate portions and the other having side flanges for receiving therebetween the first mentioned side flanges and bent into engagement with the first mentioned plate port-ion to permanently hold the plate portions in predetermined relationship, a slide movable within said casing and projecting out through the side thereof opposite to said connecting wall and having a notch therein for carrying cord ends into said casing, said slide having a shoulder, and one of said first mentioned flanges having a portion bent inwardly and forming a resilient tongue for engagement with said shoulder to prevent the outward movement of said slide.
2. A seal including a casing, formed of a single piece of metal including two plate portions and a connecting wall, said plate portions being in superposed spaced relationship with the connecting wall forming one end of the casing, one of said plate portions having side flanges for spacing the plate portions and the other having side flanges for receiving therebetween the first mentioned side flanges and bent into engagement with the first mentioned plate portion to permanently hold the plate portions in predetermined relationship, a. slide movable within said casing and projecting out through the side thereof opposite to said connecting wall and having a notch therein for carrying cord ends into said casing, said first mentioned flanges and said slide having formed integral therewith interengaging parts to prevent outward movement of said slide from its innermost position.
