ATTACHMENT FOR METAL-DRILLING MACHINES.

SPECIFICATION forming part of Letters Patent No. 634,324, dated October 3, 1899.

Application filed April l 8 1 89 9.

To all whom it may concern:

Be it known that LWILLIAM E. CANEDY, a citizen of the United States, residing at Chicago Heights, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Attachments for Metal- Drilling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to table-rests and work-clamps for vertical drilling-machines.

The object of the invention is to improve the support and holder for a drilling-machine, so that various forms of work can be grasped and held and the position of the work, either on a table or in a clamp, may be readily ad- -j usted with relation to a drill also, to improve the construction of the clamp or vise and the relation of such clamp or vise to the frame of the machine, the table, and the working-tool.

Figure 1 is a perspective view of parts of a drilling-machine, showing improved clamp in position as a work-table support. Fig. 2 is a'perspective View of clamp or vise in position to grasp arectangular object, shownin dotted lines, the standard of the drilling-ma chine and the tool being shown. Fig. 3 is a view similar to Fig. 2, showing clamp as ap: plied to a tapering object. Fig. at isa view similar to Fig. 2, showing clamp as applied to a shaft or rod. Fig. 5 is a top plan of the clamp or vise. Fig. Bis a detail elevation of supplementary work-table.

The drilling-machine A, Fig. 1, is of usual construction. Any usual form of upright drill is within the scope of the application of this invention, and the illustration, Fig. 1, is intended merely to show the relation of parts, some of the drill-driving mechanism being shown in dotted lines.

B denotes the drill-spindle, and C the worktable, both being of usual form.

On the frame of the machine there is an upright cylindrical standard D. On this standard the table-support is vertically adjustable. This support has generally been a bracket-arm, which might be split or not, but was generally held by a set-screw. The part E in the drawings resembles the usual bracket in respect to its vertical adjustment. A set-screwF clamps the part E to standard D, and it will be understood that this part or (No model.)

bracket may be, adjusted or swung laterally, as well as vertically, on the standard D as a pivot and support. The part or bracket E is extended to form one jaw of a vise or clamp. The outer end of the extension is extended upward, as at G, and a vertical notch H in the inner face of this jaw forms a holding-receptacle for rods and the like when the device is used as a clamp. The upper face of the part G forms either a work-table in itself or a rest for a supplementary table, as will be explained.

Pivoted at the side of bracket E on a V61 tical pivot is the other jaw I of the vise or clamp. This jaw I has its upper surface in the plane of the upper face of the bracket E, but below the top of G and at a right angle to the axis of standard D. Instead of afixed extension G the jaw I has a pivoted or swivpart of projection G. This pivoted piece or false jaw K has in its face a notehL, which notch is continued in jaw I as the counterpart of the notch Hin the other jaw. The false jaw K being free to turn on its pivot will adapt itself to the form of almost any substance placed between the jaws, and when the jaws are drawn together by the usual bench-vise screwM engaging the jaws in usual manner the article will be firmly clamped between the jaws. The upper surfaces of extension G and of and may be closed together to form a worktable or spread apart to hold articles between them. The jaws open and close horizontally. The supplementary table 0, which has a spindle ac, as usual, may enter the notches H H, and the table will then be held against rotation by the tightening of the jaws on the spindle, or the table may be swung or rotated by leaving the jaws a little loose, with the table-spindle in the notches.

The lower face of table 0 rests on the up per surface of false jaw K and extension G when the table is applied to the clamp, and as the bracket E affords a swivel adjustment of the clamp and table carried thereby it is apparent that the table may be swung to various positions under the drill and may be rotated or held by means of the clamp, as desirable. It is also apparent that by removing eled extension-piece K, forming the counterfalse jaw K are in the same horizontal plane the table C the clamp may be made to hold ening-screw passing through both horizontal various forms of material and in adjusted rejaws,allcombined substantially as described.

lation to the drill.

The notches U L are preferably in such relation to the standard D that the table 0 when borne on the clamp or vise will naturally center under the drill unless swung to one side, as explained. This clamp device in its present form is specially intended for use with a vertical drilling-machine, but is susceptible of other uses without change.

It is well known that there are many known forms of clamps adapted to hold the work under the drill of a drilling-machine. No broad claim is made herein for the combination of a clamp with such a machine save as the clamp or vise of this invention has special capacity for such use. The jaws extending horizontally form on their upper surface a table on which work may be held, or a further table may be supported thereon, as described.

I claim 1. Thecombination with adrilling-n1achine having an upright standard, of a vise or clamp connected to said standard and having pivoted jaws extending horizontally from such standard, one of said jaws being pivoted to the other, and means for closing said jaws in horizontal direction.

53. The combination with a drilling-machine having an upright standard, of a clamp or vise connected to said standard and having pivoted jaws extending horizontally, one of said jaws having a pivoted extension-piece at its upper face, which extension-piece automatically adjusts itself to different forms of material in the jaws, substantially as described.

3. In a work clamp or vise attachment for drills, as described, a horizontally-projecting jaw having an upward extension at its outer end, the upper face of said extension adapted for use either as a work-table or as a tablesupport, the second jaw pivoted to the first and havinga pivoted false jaw corresponding to the extension of the first jaw and cooperatin g therewith to act as a clamp, and a tightt. In a work-clamp for drills as described, the horizontally-projecting jaws pivoted to each other, the upward extension of one horizontal jaw and the pivoted false jaw on the other, both horizontal jaws having a vertical notch and the false jaw having a notch to correspond therewith, and a tightening device, all combined substantially as described.

5. In adrilling-machine ofthe characterdescribed, the combination of a vertical standard, a horizontally-proj ectin g bracket adj ustable on said standard and forming one jaw of a vise, a second jaw pivoted to the first by a pivot independent of but parallel with the standard, both jaws having vertical notches in their proximate faces, and having tightening means by which they may be closed horizontally, and a supplementary table havinga spindle which may enter said notches loosely or be held tightly therein, substantially as described.

6. In a drilling-machine, the vertical cylindrical standard, a horizontally-projecting jaw which may be swung and vertically adjusted on said standard, a second horizontal jaw pivoted to the first, means for closing the jaws horizontally and a pivoted false jaw on the upper edge of one of the horizontal jaws, which pivoted jaw is self-adjusting to the work,all combined substantially as described.

7. In a drilling-machine a vertical standard, a horizontally-projecting arm adj ustably secured to said standard and having an upward projection forming part of a work-table, a second jaw having upward projection pivoted to the first independently of the standard and also formingpart of said worktable, and means for opening and closing the jaws in horizontal direction, all combined substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

\VILLIAM E. OANEDY.
