UNITED S TES PATENT oFFron To all whom t may concern: I

Be it known that I, HENRY .RoBnR'rs, a' citlzen of the United States, residing at 'Pasadena, in the county ofLos Angeles'and State 5 of California, have invented a new. and useful Grapnel, of which the followingis a specificas tion.

It is of the objects of this'invention to provide a load-holding device adapted' to 'be readilyattached toand detached from hay and like coarse bulky material, v whether. baled or loose; to provide a trippingdevice which may be readily operated to trip the load-holding hook at ,a distance therefrom by means ofla rope or other connection, and to provide a hook with lever-operatedmeans whereby said hookimaybe readily operated to drop its load by a slight pull onia trip-rope.

This invention relates to a hoisting and releasing device adapted to be employedinconnection with the hoist and carrier described in another application for patent filed by me in the United States Patent Ofiice contempo raneously herewith, Serial No. 293,218.

Other objects and advantages may appear from the following detailed description, taken 'in connection with the accompanying drawings, illustrative of the invention, in which t Figure 1 is a side elevation of the device in load-holding position, one side of the'frame being broken away to show interior parts. .Fig. 2 is a view similar to Fig. 1, showing parts in position assumed when the hook is to drop its load. Fig. 3 is a front elevation of the device with parts in same position as in Fig. 1.

The grapnel comprises a frame, a hook pivoted thereto, and a toggle connected to lock andto operate the hook.

The frame 1 may be formed of a single piece of metal bent into a shape approximating that of aninverted U, being provided with side pieces 2 and 3 and a uniting-piece 4 at the top, which may be perforated at 4 to receive a swivel 5, having an eye 5.

6 7 8 designate pivot bolts or pins for spacing apart the side pieces 2 and 3 and pivotally supporting parts hereinafter described.

9 designates the load-carrying hook, which is provided at its upper end with a segmental gear 10, the teeth 11 of which engage teeth 12 of another segmental gear 13, having an extension 14, to each side of which is pivoted at 15 a double link 16 which is in turn pivoted at 17 to the short end of a lever 18, having Specification of Letters 'Patent. l Applicationfiled December 26,1905. semi No. 293,217.

' 4 Patented Dec. a 'lso ai i 1 its fulcrum at bolt 6, on which it is pivoted to oppositely-disposed adjacent extensions .19 oftheframelw, w mq Hook 9 is preferably provided at each side with a perforated boss 9" for receivingkbolt .8

and-spacingside pieces 2 and 3 a short distanceaway from gear 10. Gear 13 and lever '18 may likewise be respectively .provided with bosses 13 and=18..

In Fig} 1 the parts are shown in holding positionythe hook 9 being swung forward into position for-carrying a load, an eXtension 20 at theupper endof the hook abutting against extension 14 of gear 13, the pivots 6, 17, and 15 of lever -18 and link 16 being nearly in alinement, the pivot 17 being adapted to stand a'little backof the-line .toward pivot 7 to lock thGhOOk against swinging rearwardlyinto the releasing position. (Shown'in Fig. 2.) 7 Lever-18 may be provided at the upper endawith an eye 21, towhich is attached the trip-rope 22 for operating said lever to throw the hook rearwardly into the releasing position. The hook may be readily grasped by the hand and canted forward from this position for attachment to a new load. A rope or other connection 52 may be attached to eye 5 of swivel 5 for suspending the device from the hoist and carrier described in my aforementioned application 4 for patent or from any other appropriate device. v

From the foregoing description it will be readily understood that in practical operation a pull on trip-rope 22 will operatelever 18, initial gear 13 through link 16, and final gear 10, thereby swinging the point of hook 9 backwardly and releasing the load, which may thus be dropped from the hook when in an elevatedposition. pins for holding the bolts in place.

It is to be noted that the pivoted lever 18, link 16, and gear 13 form a toggle connected with the hook through its gear-teeth 11 to operate and to lock the hook '9.

Link 16 rests against bosses 13 when in 25 designates cotterstruction provides a strong and compact operating device for moving the hookfland for looking it in its holding position. i
