F. KUBERKA LIFTING Hoox Dec. 13, 1932.

Filed May 16. 1931 Patented Dec. 13, 1932 UNITED STATES FRANK KUBERKA, OF VIRGINIA, MINNESOTA LIFTING HOOK Application filed May 16,

substantially enclose the chain when in inoperative position but to have such relation with the chain in operative position as to form means for engaging cable reels and the like whereby the same can be lifted.

A further object is to provide a lifting hook which can be readily inserted in an open-A ing in the object such as cable reels when in inoperative position and which will comprise..

an effective engaging means by which the object can be safely lifted.

A further object is to provide a novel andimproved device of this character which will be easy to operate and which will fulfill all. requirements of practical operation.

With these and other objects in view, the invention may consist of certain novel fea. tures of construction and operation as will be more fully described and particularly pointed out in the specification, drawing and claims appended hereto.

In the drawing, which illustrates an embodiment of the device and wherein like reference characters are used to designate like parts- Figure 1 is a sectionalview taken substantially through the center of a cable reel showing the lifting hook of the present invention in position for lifting the same.

Figure 2 is a sectional view of a cable reel showing the lifting hook in position for insertion in the opening of the reel.

Figure 3 is an elevational view, parts being shown in section, of the lifting hook showing the same associated with a hoisting chain.

Figure 4 is a plan view of a lifting hook, and f Figure 5 is an end elevation of the hook shown in Figure 4.

Referring to Figures 3, 4; and 5 of the drawing, the lifting hook is shown as associated with a hoisting chain 10 forming part of a frame or other hoisting mechanism. The hook or cross member 12 is formed in a chan- Y means of a the same and at substantially its mid-portion 1931. Serial N0. 537,945.

nel shape,as shown in Figure 5', and by pin 14 extending transversely of the member is pivotally attached to the chain, since the lower link 16 encircles the pin. For 55 allowing free movement of the member 12 on the chain the bottom surface of the member is recessed as at 18 directly below the location ofthepin. ,Y

Attached to one end of the member 12 `is 60 an operating chain l2O, the link 22 being looped through an opening 24 formed inthe member. rlhe other end of the chain 20 is fastened to the main chain 10 by the engagement of end 26 with link 28.

. In Figures 1 and 2 there is shown a cable .reel of usual construction having a winding drum 30 and side members 32'. Central openings 34 are provided at `substantially the v center of the reel, through which the lifting means of the present invention is adapted to be inserted for engaging the reel, whereby the same may be lifted.

Referring lirst to vFigure 2, the member 12 is shown in vertical position, inwhich posi- 75 tion it can, be considered as forming a continuation of the main chain 10. Due to the channel-shaped cross section given to member 12 one end will enclose the portion of the chain 10 adjacent the pivot pin 14. In thlsxSO position the member 12 can be inserted in an opening, provided the same is just slightly larger than the diameter of the chain 10.

l/Vhen the hoisting mechanism has been lowered to an extent where the member l2 is: 85 located within drum 30 the member can be caused to assume a horizontal position with respect to the hoisting chain by means of the auxiliary operating chain 20. With the parts in this position upward movement can beimparted to the hoisting chain whereby the member 12 forms a lifting hook engaging the side member 32 at points adjacent the opening 34 and thus forms a secure and effective means whereby the cable reel can be safely lifted. fi.

It will be apparent that by a reversal of the operations explained for inserting the member 12 the same can be readily disconnected 4 from the reel and removed through opening 34. Y 10o VIt is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled inthe art without departingfromthe spirit of the invention or the scope of -vthe claims.

I claim: Y

1. A lifting hook, comprising in combination, a chain or the like having connection t'o hoisting mechanism, a member pivotallysecured to the lower end of said chain, said member being channel-shaped and having two operative positions with respect to said chain, 1one position 'with the member at rightangles tothe chain whereby the same forms a hook, fand-theother position with the member eX- itending longitudinally of the chain substanl'ti'ally yenclosing 'the chain.

2. A lifting hook, 'in combinatiomla chain -or "the like having connection to hoisting "'ir'e'oh'anism, a member pivotally securedftothe lower end of said chain, said member being ch'arinelshaped and permitting insertion in objects to be lifted when positioned longitudinallywith respect to the chain and-slibstantially enclosing the same.

i3. A1In combination, a chain or the like,hav ing connection to hoisting mechanism, land a vterminal member secured to the lower end of fsaid `chain forminga hook with 'respect th'ereto, said terminal member when Vpositioned longitudinally ofthe chain `substanfti'alllyencloses the same whereby the member mayfbe inserted and withdrawn from-'openings l*of a diameter 'substantially that of 'the chain.
