SAFETY HOOK.
7. Application filed December 30, 1926.. Seria1 No. 157,997.
The invention relates to improvements in hooks provided with guards to prevent them from becoming accidentally disengaged from parts with which they are connected.
The object of the invention is to provide an exceptionally simple and inexpensive device of this class, yet one which will be elli cient' and in every way desirable, and may fulfill any of a number of uses.
lVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.
Fig. 1 is a side elevation showing the manner in which the hook may be used for connecting a transverse tire chain to a spoke of a wheel.
Fig. 2 is a side elevation illustrating the use of the book as a repair, splice or open link.
' Fig. 3 is a side elevation showing the hook connected with a line such as a tow line or a hoisting cable. 9
Fig. i is an enlarged side elevation, partly in section, showing more particularly the construction of the hook.
Fig. 5 is an edge view.
Fig. 6 is a transverse section on line '66 of Fig. 4.
In the drawing above briefly described, the numeral 7 designates a shank having a return bend at one of its ends, providing a hook 8 whose hill 9 may be substantially parallel with the shank. This shank is formed with a longitudinal slot 10 which opens through its other end and extends from the latter to a point opposite the hill 9, at which point, said slot terminates in an end wall 11 which extends obliquely of the shank and faces away from the hook bill.
A second shank 12 has substantially half its length received in the slot 10, said second shank being pivoted between its ends at 13 to the end of the shank 7, remote from the hill 9. This second shank 12 is provided with an oblique inner end 14 which abuts the shoulder or wall 11 when the two shanks are substantially in alinement as seen in a number of the views of thedrawing, and the is provided with. an integral guard finger 16 whose free end abuts the inner edge of the hill 9, the outer edge 17 of said finger extending obliquely to and being substantially flush with the free end of the aforesaid bill 9. This edge 17 is at an obtuse angle to the shank 12 and hence there is no possibility of it catching upon extraneous objects, if the hook be used as in Fig. 3, for hoisting, towing or analogous purposes. Moreover, as the edge 17 is substantially flush with the free end of the hook 9, there .is no'possibility of the latter catching upon anything and interfering with proper operation of the hook.
Preferably, the portion of the bill 9 which is engaged by the finger 16, is V-shaped as illustrated at 18, and the free end of said finger is formed with a V-shaped groove 19 which receives this portion of the finger.
Thus, the finger and the hook bill are held against lateralbending with respect to each other. i
In any of the uses herein illustrated or in analogous uses of the device, the guard is held tightly engaged with-the hook bill by the pull upon the hook. 'Hence, there is no liability of the hook becoming accidentally released. As excellent results are obtainable from the details disclosed, they may well be followed. However, within the scope of the invention as claimed, variations may be made.
I claim 1. A device of the class described comprising a shank having a return bend at one end providing a hook whose bill extends toward the other end of the shank, said shank having a shoulder opposite said bill facing lat-' erally away from the latter, a second shank pivoted between its ends to said other end of the first named shank and normally disposed substantially in alinement therewith, said second shank having an inner end which then abuts said shoulder, and limits the movement of said inner end toward said bill, and a guard finger integral with the inner end portion of the second shank and normally abutting the edge of the aforesaid bill disposed toward the two shanks, the outer end of said second shank having means facilitating its connection with an extraneous member.
2. A device of the class described comprising a shank having a return bend at one end providing a hook whose bill extends toward the other end of the shank said shank having a longitudinal slot which opens tl'irough said other end and eXtendstherefrom to a point opposite the aforesaid. bill, said slot terminating in an oblique end wall facing laterally away from the bill, a second shank having a portion of its length received in said slot, said second shank being pivoted between its ends to said other end of the first named shank and having an oblique inner end normally abutting said oblique end wall of said slot, thereby liniiting the movement of said inner end toward said bill, and a guard finger integral with the inner end portion of the second shank and normally abutting the edge of the aforesaid bill disposed toward the two shanks, the outer end of said second shank having means facilitating its connection with an extraneous ineinber.
3. A structure as specified in claim 1; the outer edge of said finger being at an obtuse angle to the shank and being subslai'itially flush with the free end of the bill to prevent said finger and bill from hooking upon extraneous objects.
In testimony whereof I have hereunto ai'iiaed my signature,
SAMUEL K. TIBBENS.
