This invention relates to improvements in work piece supporting cradles and it consists of :the

matters hereinafter described and more particu larly pointed out in the appended claims.

One of theobjects of the invention is'to provide a a cradle for supporting a piece of work, such as a die, jig or the like, while drilling, counterboring, tapping, milling or grinding the same and which cradle, though simple in construction, is sturdy andis of such weight that it may be readily handled and moved about from one place of use to another. 3

Another object of the invention is to provide a cradle of this kind, which is rigid in use to assure accuracy of workmanship for the piece,

supported thereon and at the same time-is capable of being readily adjusted intomany difierent positions to meet many requirements as to the work piece to be supported by the cradle.

Also, it is an object of the invention to provide a device of this kind which may be arranged in ,a folded condition so as to occupy but a little space for storage in periods between uses.

Furthermorait is an object ofthe'invention to provide a deviceot this kind, from which chips, filings and small pieces removed from the .supported piece of work, and which maylodgeupon the supporting surface of the cradle, may be readily removed. 7 W l J The above mentionedobjectsof the invention,

Fig. 6 a detail vertical sectional view through a corner part of one 'ofthe framesof the cradle as taken on the line 6-5 of Fig. 1.

In general, the improved 1workgp1ece'supporting cradle includes a plurality ,of's counterpart ,frameswhich generally stand in .a upright posi- In connection with said frames'there is provided tion and each of which has parallel top and bottom rails or members andwposts which=operatively connect the top and bottomrails of each frame together at longitudinally, spaced points.

a rigid barelike means whichv extend between likev members of the frames for holding them rigidly in position. The rigid" bar-like means is of such construction and is so connected to said like members of the frames that the frames maybe readily adjusted into the desiredlaterally spaced and angularly disposed relations. As shown herein; the." frames areall of the same height and 201.

length, but said framesunder certain conditions may have different lengths.

Referring now in detail to thatembodiment o! the invention illustrated in the accompanying drawing, the improved cradle includes a plurality of generally upright, open, rectangular'unit like frames IE-+40 and a horizontally extendingrigid l connecting bar II.

The frames Ill-Illin this instance are counterparts having the same height as well as others, together with the advantages thereof will more fully appear, as the specification proceeds. I 1

In the drawingi Fig. l is a perspective viewof a work piece supporting cradle embodying thepreferred form of the invention, with the parts in one laterally spaced and angularlydisposed position. I I

Fig. 2 is a view of the cradle of Fig. -1 when supporting a piece of work that requires a-difierent spacing and angular disposition between the parts, from that appearing inFig.,1.

Fig. 3, is a perspective view illustrating. certain .ofjthe parts" of the cradle .in' akno'ckeddown condition to accommodate" a pieceof'workrequiring a further differentfiarrangementof the parts from that shown in Figs. ,1 and 2.

and length, it being more important that said units be the same in height rather than in length.

I, Eachunit-like frame in this instancecomprises top and bottom and generally horizontal parallel -'rails i2 and 13 respectively and apair of upright I connecting posts 14-44 disposed between and connecting the like ends of said rails together. It is preferable that theposts ll-.44 of each frame be parallel and they are so hereinshown. Each "rail I2 and I3; which is .herein shown "as'of a 1 substantiallyrectangular cross section, has='side,

upper and lower flat surfaces; In each;.ofsaid surfaces is one ormore longitudinal grooves l5,

. into which chips, filings and other small parts v nalv1ewthrough the cradle, on an enlarged scale, as taken on I the lined-4 of Fig. 1, when theicradlejs in a removed from the work piece supported by the acradle enter for an easy removal. Another advantage afiorded by said grooves is that they permit of'a better action when said surfaces are being groundx,

I -I preferto attach the ends. oi the rails-to the ends of the posts by means of set screws l6 as best shown in Fig. 6 so that the top surface of the top rail and the bottom surface of the bottom rail is eacha flush surface and devoid of any projecting parts. In the centerof the bottom rail is a thre aded opening I! best shown in Fig.5. 1 The rigidconneoting bar is provided with a central, longitudinally extending slot I 8, which extends substantiallyfrom end to end thereof, and has a width approximating the diameter of the opening I! just above mentioned. Preferably, this bar, which also has fiat top and bottom surfaces, has a length considerably more than that of the frames |!0.

The bottom member of each frame has associated therewith, a clamping screw N! that includes a shank "of a diameter to pass through the slot H3 in the connecting bar II. The bottom end of the shank is screw threaded to match the thread of the opening I! in the bottom rail of the frame with which it is associated. On the upper end of the shank is ahead 2| of a diameter somewhat more than thewidth of the slot l 8 in the connecting bar. This head is knurled externally as shown and is also provided with a transverse opening 22 into which the end of a simple tool may be inserted for turning the screw, clamping tight.

In assemblingthe-eradle, the two frames are disposed in an-upright condition and then the bar This inserted through said frames and engaged onthe upper surfaces of the rails [3-43.

At'this time the ends of the bar extend beyond the frames. The bar is disposed with its slot 18 exposing the threaded holes 17 in therails 13 of both frame's.- Oneof the screws 1 9 isthen insert- 'ed, threaded end down, through the slotin the bar and into the hole in its associated rail. .By turning the knurled heads of the screws by means ofthe fingers, the heads of said screws can be 'causedto' gripthe bar and clampit reasonably tight to the rails 43-13 of both :frames; This holds the frames an upright position. At this time, the frames may be moved laterally toward or awayvfromcone another and maybe turned :aiooutith' axes of the screws 19 int :the desired relative angular position required by the piece of work to be operated upon. The frames may then 1 he held inthe adjuste'd'qaosition-by tightening the ,screws and whereby the bar M is clamped .between ea'chlower rail and the head (of the associ- 'atediscrew; i

.In Fig. :2 I have shown a piece'o-f ,work 23 as supported-by the cradle'an'd as engaged at its end lportions upon the top surface of the top rails 912-12 of both frames. With the, piece of work :thus supported, it :may be drilled, ,counterbored, tapped or otherwise worked upon, either by ,machine or hand, in ajvery convenient manner. :By changing the'latera'l spacing :between the frames "and the relative 'angiularity thereof, it :is apparent that the tcradle may be used to support work pieces of manyldiiieren t shapes and sizes for-1am curate "work thereon. 1

ed upon. It i indeed safe in use and has time saving features that are appreciated by tool mak ers and other skilled mechanics and has many uses aroundshops where metal and other craftsmen are employed.

While'in describing the invention, I have re-' ferred in detail to the construction, form and ar-- 'rangement of the parts involved, the same is to be considered only in the illustrative sense so that I do not wish to be limited thereto except as may be specifically-set forth in the appended" claims.
