Application flledvAngust 9, 1920. Serial No. 402,093.

To all whom it may concern:

Be it known that I, Josn R. MARTIN, a subject of the King of Spain, and a resident of the city of New York, borough of Brookl I1, in the county of Kings andState of l\ew York, have invented a new and Improved Vise, of which the following is a full, clear, and exact description.

The invention relates to vises or work holders used on planers, Shapers, milling machines and other metal working tools, and its object is to provide a new and improved vise or work holder arranged to accurately seat the work on the base of the vise or work holder without requiring hammering the work down by the/ operator as now generally practiced. j

Another object is to permit of applying the improvement to vises or work holders as now generally constructed.

With these and other objects in view, the

invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. .Y

Figure 1 1s a plan view of the improved vise or work holder with parts shown in section;

Figure 2 is a sectional side elevation of the same on the line. 2--2 of Figure 1;

Figure-3 is a cross sec-tion of the same on the line 3 3 of Figure 1|, v l I A Figure 4 is a sectional side elevation ofthe same on the line 4-4 of Figure 1; and

Figure 5 is a face view of one of the jaws.

The base 10 of the vise or work holder is provided with the usual slotted lugs 11 adapted to be engaged by bolts for fastening the base in position on the face of the table or bed of the machine on which the vise or work holder is to be used at the time, it being understood that the attaching bolts engage the usual T-slots in the table' or bed. On

one end of the base 10 is formed an integral jaw holder 12. and the base is providedv with a longitudinally extending guideway 13 engaged by a tongue 14 on the under side of a movable jaw holder 15 mounted to slide on top ofthe base'lO. A screw rod 16 screws in the jaw holder 15 and is mounted to turn 1n a bearing 17 arranged on the end of the base 10 opposite the jaw holder 12. A crank 18 1s connected with the outer end of the screw rod 16 to permit an operator to conveniently turn: the screw rod 16 with a view to move the jaw holder 15 toward or from'the jaw holder 12.

On the outside faces of the jaw holders 12 and 15 jaws 2O and 21 are mounted to slideup and down and adapted to clamp the work between them. The jaws 20 and 21 are lheld normally in uppermost positionl with their bottoms above the face of the base 1() by springs 22, 23 interposed between the jaws and the base 10, as plainly shown in Figure 2. The jaws 20 and 21 are provided with elon ated openings 24, 25 engaged by screws 26, 2 screwing in the jaw holders 12 and 15, respectively, to hold the jaws in place on the said holders and to allow up and down movement of the said jaws.

v Vhen the jaws 2O and 21 are in normal position the work .is clamped between the jaws on correspondingly moving the jaw holder 15 toward the jaw holder 12 by the operator turning the crank 18, When this has been done, the jaws 20 and 21 with the work held between them are moved downward to seat the work firmly and uniformly on the face of the base 10. Heretofore the jaws were not movable in an up and down direction, and the work held between such Patented J an. 31, 1922. I

jaws was hammered down by the operator vided with conical recesses 0r seats 30, 31

adapted to be engaged by conical or pointed ends 32, 33 formed' on screw rods 34, 35 screwed lengthwise in the jaw holders 12 and 15, respectively. The outer polygonal ends 36, 37- of the screw7 rods 34, 35 are adapted to be engaged by a suitable key, wrench, crank or other tool, for conveniently turningv the screw rods to engage their pointed ends 32 and 33 with the seats 30 and 31 to move the jaws 20 and 21 toward theface of the base 10. It will be noticed that during this movement of the jaws 20, -21 toward the face of the base 10 the s rings 22, 23 are compressed and the worklh jaws 20 and 21 is carried downward t0 seat eld between the the 'work hrmly on the faceof the base 10.

The screws 26 and 27 are'astened in place by set screws 40 and t1 screwing in the jaw holders'12 and 15, respectively. Y

lB rom the foregoing it will be seen that by the arrangement described the jaw 21 can be readily moved towards or from the jaw l 20, and the jaws 20, 21 are normally held in llt) 'claim as new and desire to secure slidable, up and down on the uppermost position by their springs 22'and `23. While the jaws 20 and 21 are in this osition the work is clamped between the Jaws by advancing the jaw holder correspondingly, and after the work is clamped in placethe screw rods 34 and 35 are screwed up as above explained to move the jaws and 21 downward and likewise the work held between them until the work is rmly seated onto of the base .10. After the work is finis ed by the machine onY which the vise'is used then the screwsl 34 and 35 are retracted and likewise the screw rod 16 -to release the work from between the jaws and to allow the latter to return to uppermost position by. the` action of their springs 22and 23.

Having thus described my invention,l l by Letters Patenmv l 1. A vise or work holder, comprising a base, fixed andmovable jaw holders, jaws jaw holders, and means working through the jaw holders parallel to the line of movement of the mov- Lebanon able holder to engage the jaws and move the same and `the work clamped between them toward the base to seat the work on the base.

2. A. vise or workfholder, comprising a base, a fixed jaw mounted on the base and having itsV bottom normally spaced from the face .of the base and shitable with respectl thereto, a jaw movable on the base toward and from the said fixed jaw, the said jaws being adapted to hold .the work between them, the bottom of the said movable aw be? ing also normally spaced from and shiftable being adapted to hold the work between them, springs interposed between the base and the jaws to normally hold the same spaced from the face of the base, and screw rodsscrewing in the said jaw holders and having conical ends engaging the said conical seats to move the the work on the face of the said base.
