' Be it known'that I,

Wittmi GATE a citizen of the {United States, resijdin'g at New Haven, Bin the county of N Haven and State" use; Socket. wtfireiiehesgj na do hereby de= of Gonne'ct'icut; have invente'dcertaini new and useful Improvements in Cornbtha clare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

This invention relates to a combination socket wrench, and it consists in connecting a socket ratchet head to the socket handle, and utilizing the ratchet head as a receptacle for interchangeable sockets. It further consists in the novel means for detachably connecting the ratchet head to the handle, and the interchangeable sockets to the ratchet head.

Referring to the accompanying drawing:

Figure 1 represents the combined tool carrying an interchangeable socket;

Figure 2 is a detail view of the inner face of the socket handle looking in the direction of arrow a of Figure 1;

Figure 3 is a detail view of the ratchet head looking in the direction of arrow b, Figure 1;

Figure 4; is a detail View of the opposite face of the ratchet head looking in the direction of arrow 0, Figure 1;

Figure 5 is a detail broken view partly in section of the assembled ratchet head;

Figure 6 is a broken detail view partly in section of the socket handle;

Figure 7 is a broken View partly in section of the assembled tool and an interchangeable socket connected therewith;

Figure 8 is a detail view of the recessed or socket end of the interchangeable socket looking in the direction of arrow d, Figure 7 Figure 9 is an enlarged broken view of the ratchet teeth and broken view of the pawl connected therewith, and

Figure 10 represents a similar view of the ratchet teeth and pawl, but showing the latter reversed.

The combination tool consists of the handle 1 having the hex recess 2, Figures 2, 6, and 7, formed in the face of the head 3, the split spring stud 4, and the ratchet head 5.

The ratchet head 5 has the hex stem 6 adapted to register with the hex recess 2 of relation with the:handle; f The ratchet head? consistsof: two members,

2 the-handle 1: The holeor opening 7,- Figure 1n stem' 6"1s 'a trlfle' smaller thanthe split stud of 'the handle so that'the frictional -"engagement f the s litstud withthe:- sides ofthis opening 'Wlll prevent accidental disi; placement of =t-heratchet head init s workable viz: the knurled rotatable member 8, and the base 9 provided with the hex recess 10, see also Figure 7, and thesplit stud 11. The member 8 is provided with

recesses

12, 13, the former to admit a part of the socket member 9, and the latter to receive the stem 1% of the member 9. The groove 15 of the stem 14:, and the pin 16 maintain the two parts of the ratchet head in workable relation with each other.

The inner surface of the socket member 9 is provided with the teeth 17 adapted to be engaged by the spring actuated pawl 18 whose stem 19 extends through the cap 20 located in the outer surface of the member 8, Figure 3. The cap 20 is forked to receive the pawl retaining pin 21.

22 represents an interchangeable socket. In other words, one of the many different sized sockets adapted to embrace the various sizes of nuts or bolt heads. While the hex recess 23, Figure 8, may vary in size and shape in these interchangeable sockets, they will all have a stem of the same size and shape as the hex stem 2% to register with the hex recess 10 of the ratchet head, and each will be provided with an opening similar to the opening 25, Figure 7, for the split stud 11 The handle rod 26 gives the necessary working leverage for the tool. This rod is longitudinally adjustable so that the tool can engage a bolt head whenever there is room for the tool to rotate.

In operating the tool, the proper interchangeable socket member having been selected and attached thereto, the tool can be rotated right or left by simply changing the position of the pawl 18, Figures 9 and 10. I

The advantage of the split stud connection between the handle and ratchet head, and between the ratchet head and the various in tel-changeable socket members, is that the frictional engagement of these studs will effectually prevent accidental displacement of the several associated members, and they can readily be separated when necessary by an applied force greater than the frictional I engagement of the :said studs. Another ad- ,vantage of these'spring studs is thatit is not necessary to observe a close fit of the several hexagonal parts,'which may hesquare or of any other angular sha Having thus described my 1nvention, what I claimas new is:-- a g 1.
