CHAIN LINK SHAGKLE.
APPLICATION rILBD DEc.1o, 1903A OUSTAV ADOLF HEINRICH DRESLER, OF KIEL, GERMANY.
CHAIN-LINK SHACKLE.
Speeeaton of Letters'Patent.
Patented Api-n 24, 1906.
Application filed December l0. 1903. Serial No. 184.584.
To (r//Z 7071/0110 if Hm/.lj concern.'
Be it known that I, GUsTAv Anoia@ .HEIN- niCn DnnsLEn, draftsman, a subject of the King of Prussia, German Emperor, residing at Kiel, Germany, Province of Schleswig-Holstein, Karlstrasse 25, have invented certain new and useful Improvements in (hain-Link Shackles, of which the following is a specification.
This invention has for its object a connecting-shackle for chain-links in which the ends of the open link are held together by means of a closing member. The arrangement is such that this closing member is provided with re esses directed toward the interior of the chain-link and covers the connectingstuds of the link in the manner of a cap. The web or shank portion of the closing member is surrounded by a box or sleeve, which serves to reinforce the pin of the link by taking the strain.
Various advantages are attained by means of this invention. The studs of the chainlink are secured in position in such a manner that they cannot be displaced or move on any siie. The traction strains on the chain-link are taken by this reinforcing-sleeve and are not transmitted to the closing member. As a result of this the means for Vfastening the closing part to the link are subjected to but little strain, so that a comparatively weak pin is sull icient fastening means.
A further important feature is that with this novel shackle speedy release and opening is possible.
Another point is that shocks exerted upon the closing member Vfrom outside are kept from the stud ends by the sleeve-that is to say, they are uniformly distributed throughout all parts of the shackle-link.
In the accompanying drawings, Figure l shows the shackle partly in side elevation and partly in section. Fig. 2 is a section on the line A B of Fig. 1. Fig. 3 is a plan view, and Fig. el is a section on the line C D of Fig. I.
The open cham-link a is provided in the known manner with connecting-studs l) l). Over the studs b l) engages the closing member c. In this latter recesses e e are provided, so that ca p-like portions d d are formed, the recesses opening toward the interior of the chain-link u. In the constructional form here represented in cross-section, Fig. 2, these recesses present a bow shape corresponding with the studs b Obviously thestuds b bare inclosed on three sid es by the cap-like covering.
The closing member c is provided on its web portionf with a conical pin 7i, which engages in an opening in the chain-link (i. This pin 71 is secured in the link by means of a pin fi. This pin /i may advantageously be secured from falling out by means ol' a lead filling in a recess by a plug, or the like. The thickness of the web portionf is depen-'dent upon the interval ;r, Fig. 3, separating the studs l) b ofthe link a.. In oreer to permit of the introduction of the closing member c, the thickness of this part f must beI smaller, although not much smaller, than this interval '.1.
In order that a sullieiently wide chain-stay of the usual dimensions may be obtained, however, the partfof the closing member cis surrounifeil by the reinforcing-sleeve g. One end 11 of this sleeve bears against the inner side of the link (l. Its other end o serves to support the studs l) b of the link d. By means of this sleeve, therefore, the side of the connecting-studs l) l), directed toward the interior of the link, which are left exposed. by the cap-like cover, are wholly or at least partially covered. The sleeve g serves to support the studs l) b, and thereby prevents any contraction of the shackle-link in the transverse direction. The shackle-link therefore still'- ened by the sleeve g. This sleeve g also relieves the connecting pin or bolt i, which consequently may be readily and speedily withdrawn.
An important feature insuring the strength of the shackle-link is that shocks or pressures exerted on the outer side of the cap-like part c of the closing member may be directly taken by the reinforcing-sleeve g, as this part c of the closing member may likewise be supported on this sleeve, as shown in Fig. l. Consequently all strains exerted on the shackle-link, whether tractive strains in the longitudinal direction of the chain or shocks coming Vfrom outside, are distributed by .means of the reinforcing-sleeve to all Aparts of the shackle-link, thereby obviating excessive strains on any particular part. In this way the strength of the shackle-link is greatly increased.
As a result 0f its special construction great resistance is obtained in this novel shackle because it is possible to use the most suitable material both for the closing member' c and IOO for the sleeve g for supporting the strains to which these parts are liable. The independent interchangeability of the two parts must also not be underrated from the practical point of view.
The various details of the invention may be varied. Thus, for example, the connecting studs b l) may be made four sided. They may also be provided with several fillets. The recesses e in the cap-like portion d Will of course be made so as to correspond with the form of the studs b. The stay or web portion f may be of elliptical or circular cross-section. The pin h instead of being angular may, for example, be circular or oval.
' The essential features in all cases are the caplike covering of the studs b by the closing member c and the support oi the studs l) by the sleeve g.
Vhat I claim, and desire to secure by Letters Patent of the United States, is-
l. vA chain-connecting shackle comprising a link having an open section at one side, studs on the ends ofthe link at opposite sides of said open section, a closing member extending transversely across the link and at one end having a cap-like portion engaging said opposing studs and at its other end in engagement with the opposite side of the link, and a collar surrounding said connecting member and projecting outwardly in engagement with the sides of said studs and extending from said studs into engagement with the opposite side of the link.
2. A chain-connecting shackle comprising a link having an open section at one side and an opening in its opposite side, studs on the link at opposite sides of said open section, a closing member extending transversely across the link and at one end having a cap-like portion engaging said opposing studs, and at its other end received into the opening in the opposite side of the link, a collar surrounding said connecting member and projecting outwardly in engagement with the sides of said studs and extending from said studs into engagement with the opposite side of the link, said latter side of the link and the end of the closing member received therein having a registering transverse opening, and a pin received into said transverse opening to hold the closing member in operative position in the link.
3. A chain-connecting shackle comprising a link open at one side, studs on the ends of the link at opposite sides of the said opening, a closing member having a cap-like portion provided with recesses opening on its inner sides for engaging said opposing studs and a shank portion extending from the cap-like portion and terminating in a pin engaging a corresponding opening in the link, a sleeve surrounding the shank portion of the closing member between the cap-like portion and the said pin and bearing at one end against the inner side of the link and at its opposite end against the inner sides of the said studs and the cap-like portion of the closing member, and means for fastening the closing member in position on the link.
4. A chain-connecting shackle comprising a link having an open section at one side and an opening in its opposite side, studs on the link at opposite sides of said open section, a closing member extending transversely across the link, and at one end having a cap-like portion engaging said opposing studs, and at its other end having an integral portion received into the opening in the opposite side of the link, means engaging said latter portion to hold the transverse member in operative position, and means connected with the transverse member and engaging the inner sides of said studs to form a support for the same. l
In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 27 th day of November, 1903.
