A20, 17938 2,130,986 UNITED STATES PATENT OFFICE 2,130,986 CHAIN CRADLE Thomas Marriott, Fayette City, Pa., assignor to The American Steel and Wire Company of New Jersey, a corporation of New Jersey Application August 22, 1936, Serial No. 97,452 4 Claims. (Cl. 24S-_127) This invention relates to chain cradles, and, more particularly to cradles, or supports, for large hoisting chains. In many industries; such as, the steel industry, large chains are frequently employed in the han dling of heavy loads; as, for instance, where large chains are used as slings adapted to suspend loads from crane hooks, and the like. Due to the ponderous size of each link in such chains, con 10 siderable difñculty is experienced in arranging for their engagement by a crane hook, which arrangement has heretofore been accomplished manually. It is an object of the present invention to pro 15 vide a cradle into which chains may be placed, so that the terminal links thereof are properly positioned for ready engagement by a crane hook, or other hoisting device. ’ Another object is to provide a cradle into which 20 cranes may deposit the terminal links of large chains, and be quickly disengaged therefrom. Other objects and advantages will be apparent after referring to the drawing, in which: Figure 1 is a plan of a preferred form of the 25 invention; Figure 2 is a rear elevation of the device of Figure 1; Figure 3 is a side elevation; Figure 4 is a front elevation; and Figure 5 is a sectional view taken along line 30 V-V of Figure 3. of a terminal link L, when the latter is resting in the socket, as is illustrated in dotted lines in Fig ure 3, may be accommodated. A cut-away por tion 9 may be provided also for the accommoda tion of the links that are disposed crosswise to that seated in the socket. Modifications of the size and shape of the vari ous parts, illustrated herein, may be made in order to accommodate various kinds and sizes of chains or slings. 10 While I have shown and described one specific embodiment of the invention, it will be under stood that I' do not Wish to be limited exactly thereto, since various modifications may be made without departing from the scope of the inven 15 tion as defined by the following claims. I claim: 1. A chain-link holder, of integral construction comprising a base portion, an upright body se cured to said base portion, an inclined rest for 20 receiving the terminal link of a chain supported by said body adjacent the upper extremities thereof, a shelf extending outwardly from the lower extremities of said rest for giving end bear ing to such link, wall portions connecting said 25 rest and said shelf, said wall portions being pro vided With inwardly disposed flanges adjacent the edges thereof remote from said rest for closely embracing such link. 2. A device of the class described, comprising a 30 base portion, an upright body secured to said base Referring more particularly to the drawing, portion, an inclined rest supported by said body in which like reference characters refer to like parts throughout; the cradle of the present in 35 vention is comprised of a base l, of a size suflî adjacent the upper extremities thereof, a shelf cient to give adequate lateral support thereto, extending outwardly from the lower extremities of said rest, Wall portions connecting said rest and said shelf, said wall portions being provided which base is provided with apertures 2 for re with inwardly disposed flanges adjacent the edges ceiving anchor bolts. Extending upwardly from thereof remote from said rest, said shelf having a recess intermediate said flanges. 3. A device of the class described, comprising a base portion, an upright body secured to said base portion, an inclined rest supported by said body adjacent the upper extremities thereof, a shelf extending outwardly from the lower ex the base l is the main body portion 3 of the 40 cradle, which is comprised principally of a plu~ rality of reenforcing webs sloped to provide ex tensive footing upon the base. ` Atop the main body portion 3 is a sloping link rest 4, which is provided with an opening 5 inter 45 mediate its sides to provide clearance for crane hooks, or the like. The lower extremity of the ‘inclined link-rest 4, is provided with portions 6, defining a seat or socket, into which the links are adapted to be placed. The side portions 4a, 50 of the inclined link-rest are turned inwardly ad jacent the front of the cradle to provide socket enclosing flanges 1 extending from the portions 6 thereof upwardly to the plane of the top of the inclined link-rest 4. The bottom portions 6 55 of the socket are so spaced that appended links tremities of said rest, wall portions connecting said rest and said shelf, said wall portions being provided with inwardly disposed flanges adjacent the edges thereof remote from said rest, said shelf having a recess intermediate said flanges, said rest being provided with a cut-away portion at its upper edge between said wall portions, said 50 cut-away portion terminating intermediate said upper edge and said shelf. 4. A chain-link holder comprising a base por.. 55 2 ' ' 2,130,986 tion, a standard mounted thereon, a chain-link socket carried by said standard, the socket hav ing openings adjacent itsbottom to accommo date links depending from a terminal link `seated in the socket, said socket further having open cut-away portions adapted to register at least partially with the eye of a terminal link reposing therein, whereby the link may be readily engaged, lifted, replaced and disengaged Without disturb ing the holder, and Without substantial manipu lation of the link.
