STANDARD MOUNTING SOCKET AND CHAIN GRIP;

Application filed January 30, 1928. SerialNo. 250,599.

- This present invention relates to new and useful improvements in a standard mounting socket and chain grip of the type especially designed for sleighs, wagons, trucks and the like, and has for its primary object, the provision of a device of the character stated which be readily secured on the bolster or standard supporting beam beneath the body of the sleigh, wagon or truck and the chain extended across the load, firmly secured to the device and held thereby against movement. e

The invention has for another object, the provision of a device of the character stated,

" which is of simpleand inexpensive construction, composed of the minimum number of parts and highly efficient in usev A still further object of the invention resides in the production of a device of the character stated in which the socket is formed of a single blank with integral attaching arms andbearing lugs for the pivots of the bifurcated or bail-like chain holding member.

A still further object of the invention resides in the provision of a device of the character stated, in which the chain holding member is pivotally mounted at the lower inner corners of the socket receiving the standard and swings over the socket and the lower end of the standard therein, to hold the end of thechain back of the standard.

To the accomplishment of these -andrelated objects, as shall become apparent as the description proceeds, my inventionjresides in the construction, combination and arrangement of parts as shall be hereinafter more fully described, illustrated in the accompanying drawings andpointed out 'in' the claims hereunto appended.

The invention will be bestunderstood' and can be more clearly described when reference is had to the drawings forming a part of this disclosure, wherein like characters indicate like parts throughout the several views.

In the drawings Figure 1 is a plan of the blank from which i the mounting socket is formed.

Figure 2 is a perspective ofthe mounting socket and a portionof the chain grip carried thereon. a

Figure 3 is a detail section through the ing a slightly modified form of the invention.

Referring more in detail to the drawings,- it is to be noted that the device includes a socket 11 of rectangular form in cross section or plan produced "from the blank 12,

shown in Figure 1, and which is bent along I the parallel lines 13 with the vertical side portions 14 of the blank overlapping to form the outer side ofthe socket 11 and secured together by appropriate means such as the, rivets 15 as illustrated in Figures 2 and 3. The vertical side portions 14 of the blankare extended above the remainder of the body of the blank to increase slightly the outer side ofthe socket 11, as will be readily understood by referring to the drawings and thus serve as a better receiving and suppor ing socket for the standard 16; The blank 12 also has extended from its upper, and lower edges the gradually tapering extension arms 17which are secured over the upper and lower faces of the transverse supporting" beam 18 beneath the body 19 of the sleigh, wagon, truck or the like, and which is illustrated in Figure 5 as asleigh, the beam 18 being located above the sleigh runners 20. Appropriate fastening members21 such as bolts or the rivets shown in Figure 3, are em ployed for attaching the socket 11 to the beam 1.8 and are illustrated as extending through the beam 18 and the extension arms 17 of the socket blank 12. Adjacent one of the extension arms 17, preferably the lower one, are a pair of bearing lugs 22 extended from the main portion of the blank12 and adapted to be bent at'an angle to the main portion of the blank 12 and serve as bearing brackets 24, between the heads thereof and the spacing collars or sleeves 25. Thechain holding member 26 swings on thebolt, 2a over the socket 11, and the standard 16 mounted therein and the chain 27 passed over the load in: the body 119, is brought over the edge of the body 19 back of the standard 16 and passed through the chain holding member 26. The retaining or locking staple 28 ispassed transversely over one link of the chain 27,

after the latterQhasthendrawnthrough the chain holding member 26: and tightened therein, the legs ofthe staple 28 extending transversely across the chain holding member 26 and binding against the outer face of the bight portionthereofito hold and lock the chain firmly in position and prevent loosening of the chain 27 .by sliding of the latter out ofgadjustedposition in the chain holding member 26. p

In !the modifiedxform of the invention .Shownin .Figure6,the members 26 and 28 :are dispensed with'and, in place thereof there is provideda crotched chain 29 mounted by opposite ends on the bolt 24. and carrying at itscentral' portion the ring through which tll6 chain 27 is extended and held in adjusted position. therein by appropriate. means such :asa hook 31. carrie'deither bythe ring 30,-as

.shown in Figure 6, or by the chain 27. It'

is alsotobe seen that the chain-29 is illustrated as being :formed of twosections .con-

vnected bythe ringBO, although this'may be "altered as desired. An advantage of the form shown in-Figure '6; over the first form resides in the fiexibilityof the crotchedv chain 29. which may operatemore freely over the socket 11 and the'end; of the beam .18 or thunk when the device is in use. Furthermore theorotched chain 29 will rest'more easily on the socketll, instead of swinging clown- .wardly when not iniuse ,or when-,notheld :up by the chain 27. secured thereto.

As the construction of the device has thus been described inrdetail, brief.--reference is now had toits useandinodus operandi: The

device is secured on the-beam 18, as illus- =trated, and thestandard l6mounted in the socketll. After the-chain 27 is extended 1 over the load,the end of the cl1ain 27is ex-- tended through 'the chain holding member =26,.in the preferred 'form of the invention,

and thestaple 28 engaged over the chain link passing through the member 26, to bind .againstthe big-ht portion, of the latter, and

thus grip the chain 27 in its tightened position over the load, and back of the standard 16, as clearly shown in Figures 3 and 5 of the drawings. Beforethe chain can be released and removed from the load, the staple 28 must be withdrawn from over the chain 27( It may also be stated at this time that the standard 16 is firmly supported in position, owing to the construction and mounting of the socket structure. Furthermore, the socket structure alsoserves to provide a firm and strong support for the chain holding member 26 working thereover, on the bolt 24.

In the modified form of the invention shown in Figure 6, the chain 27 is passed through :the ring 30 and secured in its adjusted positiontherein by the hook 31 or other appropriate means as previously stated. This is the main difference between the modus operandi of the second form. am

the first form of the invention.

' appended claims without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specifications and drawings, shall be interpreted as illustrative and not in a limited sense.

Having. thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. A standard mountingsocket formed of and bearing'lugs provided on said blank at the lower inner corners of the socket to support a bail-like chain holding. member working over the said socket. V

3. As a new article ofmanufacture, a standardmounting socket formed from a rectangular blank withcentral tapering extensionsalong its longitudinal wide edges andadaptedtobe bent at right angles to. the body of the blank in parallel relation for mounting on opposite faces of a beam end; said blank alschaving-a pair of bearing lugs projecting from one ofitslongitudinal wide ROBERT A.
