This invention relates to improvements in of a single line or bridle line to form the two excavating shovels and, more especially, imhorizontal extensions 6, 6 that lead from the proved means for connecting the hauling line, hauling line to the sides of the bucket. It is bridle line and holding line thereto. The necessary that these two lines be of the same features of my improved connecting means length. Heretofore it has been considered are simplicity of design, strength and duranecessary or advisable to use chains for these bility. lines so that they could be made of exactly Other features and advantages of my inthe same length by providing each one with vention will appear more fully as I proceed the same number of links.

By the the line 33 of Fig. 2. use of my invention herein described, I can The present invention is an improvement employ a single cable or bridle cable and 2 on the invention shown in my prior Patent, attach the bight thereof to the connecting o No. 1,37 9,311, issued May 24, 1921. means. In case of any unevenstretching of i The present invention comp-rises a device the two sides of the bridle, it is very easy to for firmly and satisfactorily securing toshift the bight in the connector so that equalgether the loading or hauling line, its bridle ization is again established. lines or two horizontal extensions which run My improved connector includes a first I to the sides of the bucket, and the upwardly body 8 having hauling line attaching means extending holding line which is employed in therein and a pair of arms 9, .9 extending connection with the Page bucket, which is rearwardly. As here shown, the hauling line now thoroughly known to and in common use attaching means includes a tapered opening among engineers. 11 in the body and a wedge 12 co-operating As shown in the drawings, 10 indicates with said opening to hold the end of the a Page bucket, as above referred to, 5 is the hauling line 5. This holding is accomplished hauling line, 6 is the bridle line forming the by bending the line 5 back on itself around two horizontal continuations of the hauling the wedge 12 and letting the wedge withthe line which are attached to the two vertical line about it seatinthe tapered opening 11 5 side walls of the bucket at their front edges, in the body 8. and 7 is the holding line which runs diagonal- I provide a second body 13 for holding the ly upward around a sheave and down to a bight 6 of the bridle line 6. For this at- I point on the bucket in front of its center of tachment, I provide thesecond body with a gravity. It is of importance in the practical tapered opening 14 in which is a wedge 15 use of excavating buckets of this character co-operating with the said opening. The that the hauling line, holding line and two bight 6? of the bridle line is passed around horizontal extensions of the hauling line be the wedge 15 and such wedge with the line securely attached together by means which about it is then jammed or wedged in the the strains of use not only are unlikely to opening 14 to hold the bridle line. In the destroy, but which are but slightly afi'ected event that the two extensions 6, 6 at any time by wear. Flexibility in the connecting means, become uneven, it is a very simple matter to permitting relative movements of the various loosen the wedge 15, shift the bight around lines, is also of importance. the wedge to equalize the ends 6, 6 and again 7 Another feature of my invention is the proseat the wedge; The rear end of the body 13 vision of connecting means permitting the use is flared somewhat, as indicated by 13*, so 10 that the lines 6, 6 emerging therefrom will not cut over the edges. The body 13 has two forwardly projecting arms 20, 20.

I provide a third body 16 for holding the end of the holding line. This body likewise has a tapered opening 17 and is provided with a wedge 18 adapted to be seated therein. The end of' the holding line 7 is bent around this wedge and the wedge and line seated in the opening 17 in the body 16. This body 16 has a forwardly and downwardly projecting, arm 19.

The arms 9, 9; 20, 20; and 19 are all pro vided with pivot holes adapted to be alined to receivethe horizontal pivot pin 21 which is adaptedto be held in place by cotter pins. 22 22. j

While I haveshown and described certain embodiments of my invention, it is to be understood that-it is capable of many modificationsi Changes, therefore, in the construction and, arrangement may be 7 made without departing from the spirit and scope ofthe invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as permissible, in view of the prior art.

What I regard as new, and desire to secure .1 by LettersPatent, is :o

1;. In combination; a first body having hauling; line attaching. means therein, and an arm extending rearwardly therefrom; a second body having a tapered opening therein, and a wedge co-operating with said tapered opening to hold the bight of a bridle line therein, said second body having an arm extending forwardly therefrom; a third body having holding line attaching means therein, and an armextending, forwardly and downwardly therefrom; and means for pivotally connecting the arms of said three bodies- Apparatus as claimed claim 1, in which the arms mentioned are provided with :pivot pin openings and in which the pivotal connection includes a pivot pin extending through said openings.

3. Apparatus as claimed in claim 1, in. which the first body is provided with a pair- 1 of arms, the second body with a pair of arms and thefthll'd body with a single arm In combination; a hauling line; a first body-havingsaidhauling line attached thereto, and providedwith an arm extending rearwardly therefrom; a second body having a tapered opening therein; and a wedge 00- operating with said tapered opening to hold the bight. of a bridle line therein, said second body having an arm extending forwardly therefrom; means for pivotally connecting the arms of said two bodies; and means for attaching a holding line to the hauling line.

In witness whereof, I have hereunto set my hand this 19th day of January, 1931.

JOHN W. PAGE.
