RATGHET TAP AND NUT WRENCH.

To all whom, it may concern:

Be it known that I, FRANKG. MARBACH, a citizen of the United States, residing at Medina, in the county of Medina and State of Ohio, have invented certain new and useful Improvements in Ratchet Tap and Nut Wrenches and I do declare kthat the following is a full, clear-,fand exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in ratchet-wrenches and other tools; and the invention consists in the construction and coinbination of parts, substantially as shown arid described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l shows a longitudinal elevation of wrench with the ends in section and the middle broken away, but in whole lines otherwise. Fig. 2 is a perspective view, partially in plan, of the ratchet-head in the top of thetool. Fig. 3 isy a bottom or lower' end view of the tool, and Fig. 4 a perspective view of the connecting member for the tool with the wrench proper. l? ig. 5 is a view of a modification of-the tool as a whole, and' Fig. 6 is a vertical section ol' Fig. .3 at right angles to Fig. 5.

In the device as thus shown, A represents the barrel of the tool, which is tubular or cylindrical and provided with a solid lower end having an angular and preferably square hole c through the same, by means of which engagement is made with the wrenchB by the intermediate part C. The' said wrench in this instance is shown as having a socket end b for engagement by part (l and constructed at its opposite end to seat over or upon a nut to rotate the same, and part (l is a rigid reetangular connectis'g-piece which serves to operatively unite wrench B with the body A through hole a, a spring c on the side of said connecting-piece serving to hold the piece in the saidbody and to engage tool B therewith. I might ol" course engage the wrench or other tool directly in hole a oi.' the barrel or body; but the present arrangement is deemed best, for the reason that the tools used such as are found in the market Awith secluded. shanks, as iu this case, and by .the useoll union-pieceC, l. am enabled to employ 'any and all tools having such sockets and which are .id aptcdsto be used by rotation, Whether for one purpose or another, the use Specification of Letters Patent.

itself` not being'material.' However, the tool as thus shown and constructed is more espeeially designed for use in laces whch'are wholly inaccessible to wrenc es as ordinarily made and" which require room roundabout the nut to rotate them.v I

By my present construction a nut can be reached at any point however encumbered its surroundings may be, if the tool can be projected thereto. Of course in its broadest f sense I do not claim a tool having such capabilities to be wholly new.; but I am not'aware that the present construction as claimed herein has ever before been known or used. Referring now to the ratchet portion of the tool I show two separate and distinct members D and E, associated with the upper end of tube A. Thus the member` D is essentially the ratchet member, having a ratchethead cl, with right-angled channels 2 on its top and locked in main tube A b transverse' pin 3, which fixes said parts rigi( ly together. The said member D projects above or beyond the end of tube A and has a 'reduced portion or neck' 4 next beneath head d of suilicient depth to give sleeve or cap E longitudinal movement to effect engagement and disengagement of the ratchet mechanism. To ei'lect said engagen'ient, the cap E is provided with cross rod or bar 5 beneath its own'head 6, which is adapted to engage in either of the transverse channels 2 in ratchet-head d, according to its position and relation to said head, and engagement is made by pressing cap E inward and disengagement by drawing it outward, and a short set-screw 7 in the cap enters the annular channel or groove 4, forming the neck of member D, and limits the movements of` cap E in respect to said member.

An operating-handle Il is slidably engaged h head 6 ofthe ratchetcontrolling cap and as a reduced stem pored to confine the stem in said cap, but leaving it free to -be moved back and forth therein within the limits el its own length; This gives the operator full control of the tool and more or less Yrotary leverage, as he may need, and the tool is so constructed in point of length that it can be inserted and used in otherwise wholly inaccessible places. l` o this end the body or tube A may have a greater or less lengthand may also be made in dillerr'mt lengths.

vln Fig. 5 a chuck is shown which involves roo IIO

the same principle `of construction in the main, having a body A, a threaded or screwen a ing ratchet member D therein, provided with a ratchet-head d yas in Fig. 2, and channels therein adapted to be engaged by handle H through its flat-sided central portion h. The cap or sleeve E is slidable up and down Within limits determined by setscrew 9 extending into the annular s ace beneath ratchet-head d', as with screw gin Fig. 1. In this case the handle H is not movable lengthwise, thou h it might be, and it takes the place of bot handle H and fixed cross -rod or bar 5 in Fig. l.

What I claim isl. In ratchet-tools, a barrel and a ratchethead at the upper end of said barrel, and a cap sleeved over said head and the end of the barrel and provided with a cross-piece internally adapted to engage said head. l

2. A ratchet-tool having a suitable barrel,

, a ratchet member fixed in said barrel and extending above the same, a cap slidably and and provided wit rotatably engaged with said ratchet member, a cross part in said cap adapted to engage said ratchet member and means. to rotate said parts fixed in said cap.

3. A ratchet-tool havin a body and ratchet mechanism connecte therewith, said mechanism comprising a ratchet-head having open slots at right an les across its top, a slidable sleeve on said bo y and means to engage said ratchet projecting through said sleeve.

4. A ratchet-tool having a body and a ratchet connected with the top thereof, a sleeve slidably en aged over the said ratchet a handle at its top and a device in said sleeve to engage said ratchet.

In testimony whereof I sign this specification in the presence of two witnesses.
