To/ all whom it may concern,.-

-Be it known [that we, WALTER A. GARRI- GUs and ROBERT GOLLING citizens of the United States, residing at St. Elmo, in the county of Hamilton and State of Tennessee, have inventedja lnew and useful Tool-Holder, of which the following is a specification.

The invention relates to improvements 'in tool-holders.

The ob'ect of the present invention is to improve t e construction of tool-holders, and

ner or close to an o to providel a simple and comparatively inexpensive one of great strength and durability designed particularly for holding thread-cutting dies, taps and other tools and adapted to permit the dies or other tools to be quickly changed when desired. v

. A further object of the invention is to provide a tool-holder of this character adapted to be readily arran ed for operation in a corstruction, where there is but little room.

' i Another object of the invention is to arrange. the arts so that` when the tool-holder is operate the means for detachably retaining the dies or other tools in the stock will not be sub'ected to any strain.

Wit these and other objects in view the invention consists in the construction and novel combinationand arrangementof parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawings, Figure 1 is a plan view of atool-holder constructed in accordance with this invention and arranged for cutting threads `on a screw. Fig. 2 is a longitudinal Fig. 3 is a longi# Fig. 7 lis a longitudinal sectional view of the 55 same. Fig. 8 1s a perspective'view of the tap or tool carrying head.

-Like numerals of reference designate corre sponding parts in all the figures of the drawings. f

1 designates a cylindrical cas' forming the central portion of the stock o the toolholder and provided/atliametrically oppoysite points with integral projections 2 an 3.

The projection 2, Which 1s solid, is provided 65 with exterior screw-threads 4 and is ada ted to receive an interiorly-threaded hollow andle 5. The short exteriorly-threaded projection is solid in order to secure the necessary strength, and as it is exceedingly short, particularly when compared' with the other projection 3, which is hollow, it does not interfere with the operation of the tool-holder in a corner or close to an obstruction when the handle 5 is removed, and the tool-holder 75 is arranged as illustrated in Fig. 5 of the drawings. The tool-holder is then adapted to oscillate back and forth as a ratchet wrench or tool, as hereinafter more fully explained. l

The-hollow projection 3 (is providedv at its outer end with interior'scr W-threads 5xi and is adapted to receive an exteriorly-threaded hollow handle 6 of the same diameter as thev said handle 5. Within the hollow projection v is arranged a ratchet-dog 7, having a tooth 8 and adapted to engage a circular rotary head 9, removably arra ed within the cylindricalv casing and provide with peripheral teeth 10.

The tooth of the ratchet-dog is beveled at one 9o face and is provided at the opposite face with a shoulder and is adapted to be reversed for reversing the ratchet actionv of thel tool-` holder. The dog is rovided with an annular groove 11,v and it as diametrically opposite longitudinal grooves 12 and 13, fadapted to receive a projection 14 of a pin or screw 15.

The pin or screw 15, which is mounted in a with an aperture through which the stem 17 passes, and --the stem, which projects beyond LII the ca ,is lprovidedwithathumbiece or'grip" 19, a a ted to be readily aspe by the o erator or drawing the rato et-dog outwar y to bring the annular groove 11 opposite the project1on `14 to permit the d tojbe par-- tially rotated for 'reversing it. y thisv construction the tool-holder `maybe arran ed for rotating -the head 9 in l.e1-ther direction when the said tool-holder is oscillated.

-, Th`e cylindrical casing is provided at the back with an inwardly-extending annular flange` 20, forming a seat for the rotary head 9, and the front slde of the .casing 4is entirely open .the front face or edge vof the casing being flush with the outer or front face of the head 9. The teeth 'of the head extend enj tirely ac ross the periphery thereof, and the intervemn transverse grooves, which receive the. o extendentirely across the per-iphery of t e head, so that the said headi .may be readily removed from the casing.

It is prevented from dropping out of the casing when the tool-holder is not in use by means of a screw 21, having a cam-head) mounted -in a threaded aperture of the casing at one side .of the opening or chamber thereof and ada ted to project inward over .the rotary hea as clearly illustrated 1, 2, and 5 of the drawings. The cam-head is adapted to be turned to release the head 9,

which will drop .out of the casing when Athe tool-holder is inverted. When the toolholder is operated, the ratchetdog and the teeth .of the rotary head sustain all the strain and the cam-screw is not subjected t any strain.l

The rotary head 9 is provided with a central o ening for the reception of thread-cutand t e removal' of t e dies does not tary-head 24, as illustrated in Figs. 6 and 7 of the drawings, having an inner circular por- .o tion adapted to t within the casing and pro- 'vided with teeth 25, extend across the periphery of that portion ofthe head 2 4 lying within vthe casing, and the intervemng grooves extend to the real: face of the head 24, so that the dog not interfere with the removal of the head. The rotary head 24 is provided with an extension -26 and it has an. annular groove 27 to receive the cam-headed screw 21 before described. The

projecting portion or .extension is provided screws 31, mounted in threaded apertures of a rotary head fitte integral projections, the short projection .be-

in its outer face with a dovetailed way 28, 65 extending entirely across t'he head and'having op ositely-inclined walls for retalningl-a air o adjustable jaws 29 and 39 1n the way. he. jaws are adjusted by means of opposite 7o ears or projections 32 of a collet or rim 33. The collet or' rim' 33 is Iarranged on the projecting portion .of the head 24 and 1s secured to the same by screws 34 or other suitable fastening devices. The outer .ends of the jaws are engaged by the adjusting-screws and the inner ends or engaging portions oi the. jaws are adapted to grip a .tap .or .other tool, and the jaw 29-is rovided in its engaginv portion with a'V-s aped recess., Lthe an,

arly-disposed faces of which extend from the median line tothe side edges .of the jaw. The other l'aw-30 has its engaging portion tapered to t `the recess 35 of the'jaw29 #mild is provided with a central V-shaped 11017011.35 for engaging one of the corners `of a s uared tool-shank. The jaws are readiljT adjusted for clampin a. tap, a nut-receivin socket, orother too as will be readily un erstood, and the tool-receiving head 24 maybequickly detached when it is desired to -,use a .die-receiving head. l

Having thus fully 'described our invention, what w claim as new, and desire to secure by Letters Patent, is y 1. A tool-holder, Ycomprising a casilg provided at'opposite points with integr ojections, one of the projections being ho ow, and the other projection being solid .and .the solid projection bein shorter than the .other within the casing and provided with teeth, ratchet mechanism for enga ing the teeth, and hollow handles secure to the said projections, the handle of the solid projection being removable to permit the tool-holder to operate ina .Comer -01 va5r close to an obstruction.

2. A tool-holder, comprisin a casing 1:0- vided at opposite points with ong and ort I IO mg solid, a rotary head mounted 1n the casing, ratchet mechanism for enga .the head, and handles secured to the sai` projections, the handle of the'solid lprojection being, removable to permit the too -holder vto oper- 15 ate in a corner or close t an obstruction.

3. In a tool-holder, the combination .of .a stock having a casing open at one face Bild provided at the opposite face with a` roject- 1n an e forming a seat, aratc et-.dog mounter in the stockat the casing thereof, a removable rotary head fitted inI the casing and provided with ,an intermediate .annular groove andhaving teeth extending inward acrossA its perilphery beyond the dog to the inner face of t e head at the -lange or seat of the casing, so that the head may be with drawn from the casingl Without rst gaging the dog from it, said groove being as our own we have hereto affixed our signaloeated at the open fece of the casing and the tures in-the presence of two witnesses.
