Specification of Letters Patent.

Patented Nov. 25, 1919.

Application filed March 28, 1919. Serial No. 285,846.

To all whom it may concern:

Be it known that I, ERNEST O. CART- wnieirr, a citizen of the United States, residing at Springfield, in thecounty of Clark and State of Ohio, have invented certain new and useful Improvements in Grapples, of which the following is a specification.

My invention has for its object to provide a grapplewhich is especially useful in removing refuse from sewersfsumps and catch basins and depositing the same in a tank wagon or other conveyance for removal to a suitable dump.

It frequently occurs that refuse of various kinds, such as bottles, parts of metal frames, rods, pieces of wood, tubing or other waste material find their Way into sewers, catch basins and sumps. It is difficult to remove such articles from deep catch basins with the ordinary fork or scoop now in common use and it is therefore one of the objects of the present invention to provide a grapple fork device which will grasp the articles regardless of their shape and which has provisions whereby the grapple fork proper may be locked or held in its grasping condition while the refuse is being lifted out of the catch basin and placed over the collection tank wagon into which it can be readily released by the user.

Generally speaking, the device comprises a handle or pole, on one end of which isfixed a fork, and to that fork a second fork is pivoted, the second fork being provided with a lever portion to which is connected an operating rod that runs along parallel and in close juxtaposition to the handle to near its upper or outer end at which deposit in the receptacle.

The invention further includesthose novel features of construction and arrangement of parts which will be first fully described and then be specifically pointed out in the claims and illustrated in the accompanying drawing, in which plement. s V

Fig. 2 is a side elevation ofthe same.

Fig. 3 is an enlarged detail perspective view of the toggle grapple lever.

In the drawing, in which like numerals of reference indicate likeparts in all of' the figures, 1 is the handle which is made of a suitable length and to which the fixed fork 2 is secured by having its tine 3 fitted into the end of the handle, the handle being protected at this place by the usual ferrule 4. The fork 2 preferably has its tines curved to one side as at 5 and the pivoted fork 6 is similarly curved at 9 in the opposite direction, the fork 6 having its fingers deslgned to lie between the fingers of the fork 2 when the parts are positioned as shown in Fig. 2 of the drawing. The fork 6 has a lever portion 8 which is pivoted at 7 to the fork 2. The fork 6 is operated from adjacent the opposite end of the handle 1 by a device consisting of a rod 10 which connects to the lever 8 and extends along the handle to near the opposite end ofthe same, at which place the rod 10 is connected to the end 15 of a handle 13, the handle 13 having aneye portion 14 to fit overthe lugs 12 of the bracket 11 and is connected with the bracket by a link 17 that is pivoted at 18 to the catch lever 13 and at 19 to the lugs 12, the lever 13 being slotted at 16 to receive the link 17. The arrangement is such that when the lever 13 lies as shown in Fig. 2, the center 18 is closer to the handle than the center 19 and hence any pull on the rod 10 serves to hold the lever 13 tighter against thehandle and thus looks, as itwere, the fork 6 in fixed relation to the fork 2 so as to hold the matter grasped between the forks without the necessity of the operator holding the lever 13while he is manipulating the load.

When the lever 13 is moved away fromthe handle, the fork 6 can be rocked on its pivot to open the same, thus positioning the forks Figure 1 is a front elevation of the construction of the lever 13 and its cooperaa tive connections, the operator can manipulate the device in the sam manner as if there were a simple rod-like handle provided as he does not have to hold the lever 13 in place.

What I claim is l, A grapple comprising a handle, afork fixed in one end of the handle, a second fork cooperating with the first fork and pivoted thereto, a rod for operating said pivoted fork that extends along the handle, and a toggle lever device mounted on the handle and connected with the rod adjacent .to the end'of the handle which isopposite the fork.

2, A grapple comprising a handle, ;a f ork fixed to one end of said handle, a second fork cooperating with the first fork and pivoted thereto, a rod for operating said pivoted fork, a collar on the handle adjacent totheend farthest from the fork,;a f handle member connected with the rod and including a yoke portion, saidcollar having lugs adapted to project tlriroughv said yoke portion, and a link connection between said lugs, and said handle member, all being arranged whereby when said handle inember lies against said handle. the point of connection of said link with said lugs will lie in a different plane than that containing said yoke portion to thereby lock the'p'arts substantially as shown and described; a
