HOOK Filed Au 10, 193

Inventor Patented June 2a, 1938 PATENT OFFICE HOOK Erick Erickson, Astoria, Oreg. 7 Application August 10, 1937, Serial No. 158,438

2 Claims.

This inventionrelates to hooks, and the present invention is concerned with a hookof the type disclosed in Patent No. 1,237,885, granted to ,me under date of August 21, 1917.

The present invention involves certain new and useful improvements over the type of hook aforesaid, and has particular reference to improved means for securing the hook closed and from becoming accidentally detached from the work with which it may be engaged.

The invention together with its objects and advantages will be'best understoodfrom a study of the following description taken in connection with the accompanyingdrawing, wherein:

Figure 1 is a side view of the hook with certain parts broken away and shown in section.

Figure 2 is a top plan view of the hook. Figure 3 is a sectional view taken substantially on'the line 33 of Figure 2, and 20 Figure 4 is a fragmentary view of thesheath and sleeve constituting the free end construction of a keeper unit. 7

Referring to the drawing by reference numerals it will be seen that in the preferred embodiment thereof the hook comprises a body I having an integral bill 2. A clevis 3 is connected with the body I through the medium of a bolt and nut 4.

Further there is provided a keeper unit 5 which at one end is notched or recessed as at 6 to receive the end of the body 1. remote from the bill 2, and the keeper unit 5 is pivoted to the body I.

through the medium ofY the' aforementioned bolt At said slotted end the keeper 5 is provided with a peripheral groove I I which accommodates a looking or retaining sleeve I2.

Sleeve l2 is'of a length slightly less than the length of the groove II and is rotatable about the keeper 5 as an axis.

Sleeve I2 is provided with a notch I3 that is adapted to aline with the underside of the slot -'1 in the keeper 5 so as to permit free passage of the bill 2 into and out of the slot 1.

With the bill 2 arranged in the slot 1 the same 7 is retained in said slot against casual displacement by rotating the sleeve, 12' for positioning the notch 13 in the sleeve out of alinement with the bottom side of the slot 1 or to the position shown in the drawing.

It is believed to be clearly apparent that with the sleeve in the mentioned position a separation of the bill 2 and keeper 5 is positively precluded.

To disengage the hook and keeper, it is only necessary to rotate the sleeve 12 to aline the notch 5 7 13 therein with the bottom of the slot 1. This leaves the bill 2 free to pass out of the slot throug the bottom side of the latter.

In conclusion and briefly stated, the hook embodying my invention comprises a body and a 10 belt. A keeper is pivoted to the body of a hook at one end of the hook remote from the bill, and is provided at its free end with a sheath for receiving the bill of the hook. Mounted on the keeper, and rotatable about the axis of the keeper 15 is a sleeve adapted to retain the cell in the sheath. The sleeve is provided with a notch which is adapted to align with the open side of the sheath to permit movement of the bill into and out of the sheath.

It will thus be seen that I have provided a hook 'which is so equipped as to positively retain the hook engaged with the work such as the link of .a chain, or the like, and that the means for re:

' taining the hook 'so positively engaged with the work has numerous advantages over the hook shown in my aforementioned patent,'as will be clearly appreciated by those skilled in the art.

Having thus described the invention what is F claimed as new is:

V 1. A hook comprising a body and a bill, a keeper pivoted to the body of the hook at the end of the hook body remote from the bill, and said keeper at thefree end thereof being provided witha sheath for receiving the bill, and a sleeve on said end of thekeeper and rotatable about the keeper as an axis, said sleeve being engageable with the bill for retaining the latter within said i sheath, andsaid sleeve beingv also provided with a notch adapted to aline with the open side of said sheath to. permit movement of the bill into and out of said sheath.

2. A hook comprising a body and a bill, a keeper pivoted to the body of'a hook at the end of the body'remote from the bill, and said keeper at 45 the free end thereof being provided'with a sheath 7 i ERICK ERICKSEN.
