`Implication filed It'ovember 12, v192.5. Serial No. 687,614..

To all whom t may concern.'

.Be it known that we, Grenen l- N. Dow and Grenen J. J. CLARK, citizens of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented a new and useful'Hook, of which the following is a specification.

This invention aims to provide novel means for connecting a pair of chains, lfor connecting-the ends of a chain, or thelike, iu such a way that the aforesaid objects will be prevented from becoming separated accidentally, it being possible to effect ya separation readily, at the will of an operator.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention; Figure 2 is a plan; Figure 8 is a longitudinal section wherein parts reni-ain in elevation; Figure 4 is a fragmental longitudinal section taken in a plane about at right angles to the cuttingplane in Figure 8; Figure 5 is an elevation wherein the seats of thebody and of the disks have been alined for the reception of one link of the.

chain; Figure 6 is a sectional view showing the parts as they will appear after one link of the chain has been pushed into the registering seats of the body and of the disks; Figure 7 is an edge view illustrating a slight modification in one of the disks.

The device forming the subject matter of this application preferably is made of metal throughout and includes a body 1 comprising a shank 2 and spaced arms 3, the shank 2 being supplied with a connector, such as a hook 4, adapted to engage one end of a chain 5. A shaft 6 is mounted in the arms 8 and form part of the body 1. That end of the arms 3 which is` opposite to the con nector 4 is provided with seats 7. Y ,Y Spaced disks 8 are located between the arms 3 and are mounted to rotate on the shaft 6. In their edges, the disks 8 have 60 seats 9 adapted to be brought into registration with each other, andvinto Vregistration with the seats 7 of the body 1.VK In orderto facilitate a rotation of the disks 8, the same may be provided in their edges with depressions 18, although, if desired, the edges of the disks may be milled, as shown at 28 in Figure 7 in connection with the disks 8.

The numeral 10 marks a hook comprising an outer arm 15 and an inner arm 17 con- 70 nected by a bend 16, the inner arm 17 liaving an eye or bearing 12 mounted on the shaft 6, the hook 10 extending between the disks 8. The hook 10 is adapted to receive a chain 11 or the like, `and the end 14fof the 75 outer arm 15 moves close to the periphery of the disks 8. The inner edge of the arm 17 forms a cam 19.

Generally considered, the device forming the subject matter of this application comprises a body 1 provided at one end with a connector 4 and supplied atits opposite end with a seat 7, a disk 8 being provided, the disk having a seat9, and the disk 8 be? ing journaled, at 6, on the body 1, to permit the seat 9 of the disk 8 and theseat 7 of the body 1 to be .brought into registran tion. The hook 10 comprises an inner arm 17 and an outer arm 15, a bend 16 connecting the arms, and a bearing 12 being carried 90 by the inner arm 17, the bearing 12 alfording means whereby the hook 10 isV mounted for swinging movement on the body 1, in a 4 plane parallel to the disk 8. The free end 14 of the outer arm 15 is so located with re- 95 spect to the periphery of the disk 8 that an object 11, carried by the hook, can be disengaged from the hook only when the seats 7-9 are brought into registration, as in Figure 5, and when the hook 10 is swung 100 to open position, to cause the said end 14 ofthe outer arm 15 to clear the seats 7.v As hereinbefore stated, the inner arm 17 is provided with a cam 19, and the inner arm 17 is so inclined, Ifrom the bend 16 to 105 the bearing 12, that the cam 19 is inclined with respect to a straight line passing through the connector 4 and the bend 16. The construction is such that when an object 11, engaged by the bend 16, is moved into the seats 7 9, from the position of Figure 5 to the position of Figure G, the seid object will cooperate with the cem 19 and swing the hook 10, as in Figure 6, toward the eforesaidopen position. It is necessary, then, for the operator to give merely a, slight swinging movement to the hook 10, to cause the end 14 of the arm 15 to clear the registering seats 7-9, whereupon the obje-et 10 may be pulled out of the seats, in u way which will be clearly obvious when Figure is noted, the elements l0 and 5 thus being separated. f

What is claimed is:-

A device of the class described comprising a, body provided et one end with u connector and supplied at its opposite end with e seat, e disk having` a seat, the disk being journaled on the body to permit the .seats of the disk and of the body to be brought into registration; e hook comprising inner and outer arms, u bend connecting the arms. and a bearing carried by the inner arm, the beering affording means whereby the hook is mounted for swinging movement on the body, in e plane parallel to the disk, the free end o thc outer arm being so located with respect t0 the periphery of the disk that an object, carried by the hook, can be disengaged from the hook, only when the sent-s are brought into registration and when the hook is swung to open position to cause seid end of the outer arm to clear the seats, the inner arm being provided with :L eem, and the inner erm being so inclined, from the bend to the bearing, that the cani is inclined with respect to e straight line passing through the connector und the bend, whereby, when an object, engaged by the bend, is moved into the seats, the object will cooperate with the earn to swing the hook toward the aforesaid open position.

in testimony that we claim the foregoing as our1 own, we have hereto znixed our sig"- natures.
