BENG'I. M. W. HANSON, 0F HARTFORD, CONNECTICUT, ASSIGNOR TO PRATT & WHITNEY COMPANY, OF HARTFORE CONNECTICUT, A CORPORATION OF NEW JERSEY.

TOOL-HOLDER.

To all whom it may concern;

Be it known that I, BENer M. W. HAN- soN, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Tool- Holders, of which the following is a specification.

This invention relates to tool-holders the object of the invention being to provide an effective device of this character capable of rigidly and adjustably holding one or more tools.

A tool-holder comprising my invention is adapted for advantageous use in many different connections being especially adapted however for application to fiat-top turretlathes.

In the drawings accompanying and forming part of the present specification I have represented in detail one convenientform of embodiment of the invention which to enable those skilled in the art to practice the same will be fully set forth in the following description while the novelty of the invention will be included in the claims suc ceeding said description. From the statement just made it will be apparent that I do not restrict myself to the disclosure made by said drawings and description for certain variations may be adopted within the spirit of my invention as expressed in said claims.

Referring to said drawings, Figure 1 is a top plan view of a tool-holder embodying my invention, and, Figs. 2 and 3 are sectional views on the lines 2-2 and 33 respectively of Fig. 1 looking in the direction of the arrows in the latter.

Like characters refer to like throughout the several figures.

It is my custom to make the tool holder in the form of a lower section or portion and an upper section or portion the space between the two sections being intended for the reception and adjustment thereinof one or more tools of suitable nature. Said lower and upper portions may consist of plates as 2 and 3 disposed in superposed relation. The lower or base plate 2 of the tool-holder parts Specification of Letters Patent.

may be connected with the turret-top in any suitable manner for example by the row of clamping screws 4: passed through countersunk holes therein and tapped into said top. (Not shown.) It might be stated that for convenience the heads of said screws fit in the countersunk portions of said holes.

.The two plates 2 and 3 may be maintained at the desired distance from each other in any suitable manner; for this purpose I have shown spacers consisting of sleeves 5 of which in the present instance there are fourone at each corner of the device. In like manner any suitable means may be provided for holding the two plates 2 and 3 in clamped relation although bolts as 6 answer satisfactorily my purpose in this respect, the shanks of said bolts being extended through said spacing sleeves 5 while the heads 7 thereof bear against the upper surface of the upper plate 8. The nuts 8 of said bolts fit and slide in tee grooves 9 extending uninterruptedly from one side of the base plate 2 to the other at the front and rear thereof. The shanks of said bolts also pass through slots 10 at the front and rear of-the upper plate said slots extending as nearly as practicable from one side to the other side of said upper plate so as to insure a wide range of lateral adjustment of the two pairs of bolts 6. One pair of bolts 6 can be adjusted toward and from the other or vice versa and during the adjustment of said bolts the shanks thereof more along the elongated slots 10 while the nuts 8 thereof slide along the grooves 9.

As indicated the space or interval between the two plates 2 and 3 provides a passage or chamber for receiving the tools of which there may be any suitable number or only one while owing to the construction hereinafter described said tools can be adjusted freely laterally of the device and rigidly held in their adjusted positions.

I have shown a tool 11 in Fig. 2 as held in an adjusted position and at this time it is preferably borne by the base plate 2 and is substantially clamped thereto by front and rear binding screws as 12, there being as will be evident on inspection of Fig. 1 three section so as to prevent the same turning in said slots when said binding screws are run either in or out. Said nut-sleeves are shown as provided with base or foot-flanges 14 adapted to bear against the under face of the upper plate 3. The lower ends of each pair of screws 12 therefore engage a tool 11 to clamp the same firmly against the base plate 2 as shown both in Figs. 2 and 3 in full and dotted lines respectively. By backing out a pair of cooperating screws 12 the tool 11 held thereby will be freed so that the tool and the cooperating screws and nutsleeves 13 can be moved laterally of the toolholder for adjusting purposes and when the adjustment is secured the screws 12 will. be run down to again clamp the tool to the base-plate 2. The heads of the screws 12 are made large enough to prevent their passage through the slots 10 so that when a tool is released from the influence of a pair of holding screws there is no possibility of the said screws and the cooperating nuts or sleeves l3 dropping all the way from the slots 10 onto the base plate 2 although they may descend a short distance or until said heads strike the upper plate.

Initially the lower and upper plates 2 and 3 are rigidly associated with each other and this of course is done by turning the corner bolts hen this takes place the plates are drawn together and at the same time are caused solidly to abut against the intermediate spacing sleeves 5, the nuts 8 bearing solidly against the upper part of the wide portion of the grooves 9 and the heads 7 of the said bolts bearing equally so against the upper surface of the upper plate by virtue of which the two plates will be as rigidly tied together or connected as though they were integral. It should be stated at this point that to prevent said nuts 8 from turning I provide the same with rectangular portions 8 which fit somewhat closely the narrow parts of the tee grooves 9. After the plates are thus connected the tools 11 can be freely adjusted. The manner in which the tools are adjusted and that in which the bolts 6 are adjusted are so obvious that it is not deemed necessary to specifically describe this any more than has already been done. The screws 4t can be removed to change an adjustment of the tool-holder as a unit or whole by passing the hand into the space between the lower and upper plate or the upper plate can be removed to get at said screws 41-.

eaaeee By virtue of the construction set forth I am enabled to position a tool at practically any point between the sides of the toolholder; that is I can position said tool at any point in the length of the parallel slots 10. For example the two series of corner bolts 6 are shown as being at'the' outer extremes of their adjustments. I might move two front and rear alined bolts side-wise and place exactly where they are the nutsleeves 13, and the screws 12 in which event the tool held thereby would be precisely where the spacing sleeves 5 of said bolts are shown. By this organization therefore I can get not only maximum sidewise adjustment but can locate a tool to operate upon any portion of the work.

What I claim is:

1. A tool-holder comprising a lower plate, an upper plate having an elongated laterally extending slot, and clamping bolts connecting the plates, extending through said slot and provided with spacing devices for sepa rating the plates.

2. A tool-holder comprising a lower plate, an upper plate having an elongated laterally-extending slot, clamping bolts for connecting the plates, extending through said slot and provided with spacing devices for separating the plates, and a nut-sleeve adjustable in said slot.

3. A tool-holder comprising a lower plate having a tee-groove therein, an upper plate having an elongated laterally-extending slot, bolts extending through the said slot and adjustable therein and having each a part slidable in said groove, and means for spacing the plates from each other.

4:. A tool-holder comprising a lower plate, an upper plate having an elongated laterally-extending slot, bolts connecting the plates in clamped relation, extending through and adjustable in said slot, and means for spacing the plates.

A tool-holder comprising a lower plate having a tee groove, an upper plate having an elongated laterally extending slot, bolts extending through and adjustable in said slot, having nuts slidable in said groove, and spacing sleeves encircling the respective bolts and bearing against the plates.

6. A tool-holder comprising a lower plate, an upper plate having an elongated laterally-extending slot, bolts for connecting said plates in rigid relation, extending through and adjustable in said slot, means for spacing the plates from each other, and a nut-sleeve adjustable and non-rotatively fitted in said slot and said nut-sleeve being adapted to receive a binding-screw to engage the work between said plates.

7. A tool-holder comprising a lower plate having a tee-groove therein, an upper plate having an elongated laterally-extending With said nut-sleeve.
