Specification of Letters Patent.

Paeeneeanec. 2e, 190e.

Application filed AOctober 9, 1908. Serial No. 457,020.

Be it known that I, JOHN F. WING, a citizen of the United States, and a resident of Maywood, county of Cook, and State of Illinois, have invented certain new and useul AImprovements in Car-Seals, of which the iollowing is a specification, and which are"illustrated in the accompanying drawings, forming a part thereof. I

The invention relates to sealing devices for hasps to prevent or detect unauthorized opening, and take their name `from the fact that they are ordinarily used in connection with railway cars.

The object vof the invention is to provide a seal which while being simple of construe! tion and easy of manipulation for effecting its closure, will be secure against tampering.

4The seal comprises an apertured sheet metal head and a shackle member, also of sheet metal, adapted to be inserted within the head, there being a tongue located within the vhead for engaging an aperture in the shackle to prevent its withdrawal.

v More speciiically the invention consists of the structure hereinafter described,v and which is illustrated in the accompanying drawings, in which- Figure 1 is a perspective of the device unsettled; Fig. 2 is a longitudinal section of the same revealingy the flat face of vthe shackle and showing theA engagement of the latter with the tongue of the head; Fig.A 3 is a detail longitudinal section through the head of the device, in a plane perpendicular to that of Fig. 2 and showin one form of construction; Fig. 4 is a blan from which the head of Fig. 3 is formed; F ig'. 5- is a longitudinal section of the device in a plane perpendicular to the flat face of the shackle, showing a modified form of construction; and Fig. 6 is a detail of the blank from which the strueln the form of construction illustrated in the first iour'iigures, the head and. shackle are of separate ieces. The head'is formed of a blank 10, aving a pair of projecting tongues 11, 12, which are barbed, as shown at 13. In forming u` the head the tongues 11, 12, are folded bac to the position shown in Fig. 3, their tips being directed obliquely away from the'body portion of the blank. The blank is folded along its median line between the two tongues, its side edges-being crimped or seamed together.

Lips 14, 1,5, project from the end ol' the blank opposite the tongues 11, 12, and are folded down to close the rear end of the chamber of the head.

The shackle may consist of a separate strip lof sheet metal 16, both ends of which are to be inserted within the head, as shown in Figs. 1', 2 and 3; or it may consist of a'strip of sheet metal 17 integral with the head, aS shown in Figs. 5 and 6, one end only being free. Adjacent the free end or each end ofthe shackle there is struck u a tapering tongue 18, the narrower end o which is directed away from the shackle end. In` triking up this tongue there is, of course, le t an aper ture 19 of corresponding sha e.` The base of this aperture is of such wi th as to permit. the entry ofthe barbs ofthe tongue 11'.or 12. The tongue 18 is struck up soas to project from the 'outer face of the shackle. 4When the shackle end is inserted into the throat of the head 20, it encounters and deilects the tongue, as 11,. of' the-head, with which it c0- operates, the tongue 18 being also deflected sufficiently to pass the former tongue. The shackle being now partially withdrawn, the tongue 1S having assumed its normal position bears u on the opposite face of the tongue 11 an forces it into the aperture 19. The parts are now locked against disengagement without mutilation. The shackle cannot, of course, be further withdrawn, nor can' it be disengaged from the tongue 11 by inward movement, as the'barbs 13 will slide along the lower surface (reference being had to Fig. 3 of the drawings) ofthe shackle to or towards the contracted end of the aperture 19. This action is to be depended upon because of theoblique position of the tongue 11, but any possible uncertainty of it can be removed by bonding the tips of the barbs 13 slightlyto cause them to incline away from the face of the shackle with which they are intended to vcooperate in this movement. The action is the same Whether one or both ends of the shackle be insertible. The throat of the head is so constructed that no space is left for the insertion of a blade, and

even if inserted it could not control theengagingelements. There is shown the usual telltale mark or aperture 21 in the shackle to indicate that the seal has not beentampered with by cutting the shackle and then insert- Jwyriafoco of being directed backwardy therefrom, providing on oporturoof simar shape, the base oi which is of sufcient Width' to receive th barbed o., a, ohoml tongue, X' oat and a 3. 1n a om* seal, in combination, a, chama-:cdly from bored head having an. open' throat and atnc chamber barbed tongue projecting backwardy from che throat and obquely across the Chamber head and having an end adapted to enter ho i throat thereof and having a barb-cceivng c of suaperture adjacent cud, such opomc ooo of mo ing tapered, the 'oase of the aperture being a cham Width to permit the passage of the barbed 1 aff, :md o tongue.
