f 0 all u-Zzo-m-it may concern p Be it known that I, VVOLF S ITH. a c1ti- Zen of theUnited-States; residing at Philadelphia, in the county of Philadelphia and.

State of Pennsylvania, have invented certain new and useful .lmprovements in 'Littmg Devices, of WlllCllt-llfi follow ng 15 a.

specification. y 1 I I One obJect of my inventionis to. provide an improved lifting device which can be used with safety in connection'withcables, chalns or other-hftmgapparatus and which will include detentlocking means soarranged and constructed that a'ftenconnection ofany looped member, such as an eye or chain link, with-the hook that said looped member during the; lifting operation cannot he accidentally detached from the hook.

Another object is to, so construct my. i1nproved device that certain of the. parts thereof will be'so shapedthatiwhen'engaged bya looped member, ames that above .described in' theattempt to attach said member thereto, said parts will serve tocorrectly deflect and guide said member into the hook.

A further object isto' makethev device of my present invention of a simple and durable construction which can withstand rough i face 22: andjthe arm 15" provides a'wedge' shape space 23 which forms a, continuation usage without getting out of order.

These ob ects "and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which I 1 Figurel'is an elevational viewshowing a device made 1n accordance wlth my present invention, Figure 2 is a side view of the device shown in Figure 1, i V

Figure 3 is a sectional view taken on the line 33 of Figure 1, and g Figure 4 is a view of the same general character as that shown in Figure .1 illusstratinghow an eye or looped member may be quickly and positively connected-thereto. Referring to the drawings, 5 represents a shank eye which has a hook ,6 depending therefrom; said hook being curved to provide a recess 7 which,,at theleft sideof a vertical'plane passing centrally through the eye, is made partially elliptical. Said re cess at its bottom is continued to providea cradle or pocket 8. The end 9 of the hook 6 has a notch 10 therein which provides a ledge llfor the purpose of forming an abutdevice so tending into a slot-14 in a retaining arm 15' which leads downwardly from the shank eye 5.

Apivot pin lGeXtends arm 1 1 5 andthrough the end of said ldetent latch in a convex curve nient for 511 5 12 ofaclete t latch is; .ai'aii detent latch at its end. opposite, the lip12exso as to pivotally connect the detent latch to the arm, .15. The surface 17 ofthejdetent' latoh 131when in the position shown in. Fig;

ure 1 is in. alignment'withtheisur face 18 tends at an incline as clearly illustratedi The'lowenportion of the hookhas a curved:

surface; 19 which leads-upwardly to [the extreme free end of the hook and the lower" end 20 of the arm .15 .is spaced from said'fsurface 19;to.provide a'mouth or en-. trance openingQL, -Theilupper wall ofslot ward movement of thelatchk The dete nt latch 13 .when i its (nae no? sition' as shown inIFigure- I has its bottom surface-22 slantingnpwardlyi from the end 9.61" the hook and the space between this surof the mouth'orentranceopening 21.

Theshank eye 5 forms a means of connection with a cable. OIfiGhiLll'l(IlOlilllllSllI'atetl) for example that Y an eyelet or chain link 24l in Figure 4. It is .merelyfnecessary to move the looped memberor link relatively to the which. partially forms-:saidpocket 8 and exr" ter the 'opening2l but t'o limitfurther up -v V V and during theu'se-of the device, considering v f a that said member-initially engages p the surface 19 and by keepingsaid member in contact with said surface :durlng a relative movement between the device and said member, the member. will be gu ded into the into-the extension 23 whereit will be compelled to swing the detent latch .13 on its 1005 mouth or. entrance opening 21 and upwardly pivot 16 andithe surface 22 of said vdetent latch will guide the member 24 into the cradle or pocket 18 after which the detent latch will automatically move into 1ts closed 'positionan'd thereby lock the looped meniber to the device. Thus considermg that the device isheld stationary andthe looped mem tersPatent is ber 24 is moved upwardly the latter can be attached to the device by a single upward continuous movement after once contacting and holding the member 22 in engagement with the guiding surface 19 and it is not 11615 essary on the part ot'the workman to'diiect his attention to casting or hooking the member 2i over the hook since the deflecting portions provided by the surface 19, the arm 15, and the detent latch 13' Will automatically cause the looped member to be cast upon the hook and rest within the cradle S.

lVhile I have described my invention taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hencel do not limit myselfto the precise constructionzset torth, but consider that I am. at liberty to mako'such changes and alterations asifairly some within the scope of the appended claims. Having thus described my invention, what I claim as new and desire to, secure by Let- 1.- A lifting device including a depend ing hook adaptedto sustain the lozuh d wardly extending rctainii j arni spaced, the hook. and a gravity latch piv Y mounted in the retaining arm and adapted to bridge the space between the hook and the retaining arm. '7 I I x 2 A llftlng-, device including a depending hook adapted to sustain the load, a downwardly extending retainlng arm spaced from I the hookiand provided with. aslot, .a latch pivotally mounted in the slot and adapted bridge the upper part Of; the space between to bridge the gap between the hook and the retaining arnn 1 p g I 1 3. A lifting device including a depending hook, adapted t sustain the load the up- 4 end. said device having a downwardly ex 5 tending ar1n,'t'he lower end. olT-which is spaced from the end of said hook said end of the hook having a deflecting surface leading upwardly and forming a part of the boundary ot' the space between said hook end and the end of said arm; and a detent latch p'votally connected to saidarm at a position above the lower. end of said; arm and adapted "to 7 swing in one direction into a position to said hook end and said-arm said latch being adapted to swing inv anotherdirection. into a. position so as to slant upwardly toward the side of saidhook; substantially as described.
