WORK-HOLDER FOR METAL-WORKING MACHINES.

- Specification 0i Letters Patent. P t nted 13,'19 0 Application filed March 9, 1918. Serial No. 221,424.

To all whom itmag concern: 1

Be it known that I, HERBERT- G. Bnnnn, a citizen. of the United States of America, and resident of Pawtucket; in the-county of Providence and State of Rhode Island, have invented new and useful Improvements in Work-Holders for Metal-Working Machines, of which the following is a specification. 1 r i This invention relates to work holders or vises adapted for use with machine tools such as milling machines and drill'presses, having for its principalobjects-to provide improved means for securing to a table on bed rectangular, irregular or round pieces of work; to provide a deviceadapt'edto be readily changed from a square-jawed vise to a horizontal V-vise and to provide improved means for collectmg and removing chips adapted to avoid clogging the visel'and the ways of the table or bed and to perm1t saving of lubricant usually applied to the work and the cutter or drill.

In the accompanying drawings,-

Figure 1 is a plan View of a machine table or bed provided with the improved.

Fig.2 is a front elevation partly in vertical section; W

Fig. 3 is a vertical section on an enlarged scale on line v3-3 of Fig. 2, showing the parts adjusted to provide a square-jawed vise;and 'j Fig. 4 is asection similar to Fig. 3 showing the parts adjusted to form a horizontal V-vise for round work. I v p The vise comprises a base 1 which maybe substantially rectangular and of any desired length' or width, for instance as shown, having bottomwebs 2 facedofi flat to sit on the machine table B, and if desired provided with oneor more gibs 3 to position the vise in a groove 8 in the table B, and with any suitable means such as the square clamp nuts 4 and bo1ts-5 in bores through and having heads-6- on shoulders 7 at the ends of the upper face of base 1, to take into the grooves 8 in the table B to hold the vise in place.

One edge of base 1 may be formed with a longitudinal oil-gutter 9, and on the upper face of the base 1. a transverse undercut slot 10 may be provided to receive a guide roller 11 mounted on the under side of the movable jaw 12.

A fixed jaw 14 may be made as a block of metal triangular in cross section as shown, two of its faces being at right angles, and on one of'these faces'and the third face gibs l5 and 1 6 respectively each adaptedto seat in the groove 10 are provided. The faces of-the block 14 provided with the gibs and 16 also are provided with threaded bores adapted respectively, and interchangeably, to receive bolts 17 in holes inthe base' 1,'or bolts 18 in transverse slots 19, 19,-

an auxiliary jaw member 20, which may have transverse grooves 21, 22, to seat; over the gibs 15, 16, as shown. The movable jaw 12 is provided with a preferably integral tubular extension 25 adapted to be guided independently of the roll 11 in a bore 26 in a bracket 27 bolted at 28 to one edge of the base 1. Extension 25 is provided with a nut 24 fastened to it as by pins 29, to cooperate with a preferably left-hand screw 30 having a shoulder at 31 to prevent its axial motion through a bearing hold provided in bracket 27, the outer end of the screw having a bearing part 32 and reduced seat 33 for a hand-wheel 34 keyed tothe screw; or the outer part 33 may be squared for a wrench if preferred. I Each jaw is provided with easily attached and removed rectangular faces 35, 35, (Fig. 3) which if desired may be wholly unattached. Movable jaw 12 is also adapted to be equipped, with a triangular block 36 when the vise is to be used as a V-vise, said block being adapted to be attached to the jaw 12 as by screws 37, or by vertical dove-tail gibs, not shown, or in-any convenient manner.

When thedevice is to be employedas a flat vise, the parts are positioned as in Fig 3, the gib 15 being underneath and the member 20 not in use. To use as a V-vise the faces 35, 35, are removed, the block 36 attached to the movable jaw 12, the block 14 turned over, and attached by screws 17 as shown in Fig. 4, the member 20 being mounted in the position shown in Fig.- 4 by screws :18,- thus permitting the member 20 to be so placed aS not to interfere with a cutter or drill working from above.

The vise comprises one member of an interlocking coupling adapted to engage with another member of such coupling on a portable chip-tray 40 arranged to receive chips from work held in the vise.

The base 1 at each end for instance is cut away to provide overhanging transverse ribs 39, 39, under which the chip-trays 40,

40, are adapted to be engaged. These trays may be integral castings or stampings having a rib ll adapted to engage behind the rib 39 and to be coupled to the base 1 of the vise, and are provided with sides l2 and ends 43 to form a chip-receiving open scoop or dish which may have if desired any con venient form of handle 41-4. The trays are provided with a strainer opening at 4:5, in which a wire cloth strainer 46 is fastened in any convenient manner. The trays 40 may be disengaged by lifting their outer ends, and sliding them laterally.

The oil gutter 9 delivers into the trays 10, and only chips forced or brushed endwise out of the vise are taken into the trays, which can be emptied from time to time of the comparatively well-drained chips accumulating in them.

The machine table B usually is rovided with an oil-gutter 4L7 into which t e openings 45 drain.

F or large round work, the arrangement of the block 14 and member 20 shown in Fig. 3 or in Fig. l may be employed without the block 36, with or without the face 35.

I claim:

1. A vise adapted to be used as a flat vise or V-vise comprising a base, j aw-moving means, a movable jaw adapted to be moved by said means suitably guided on the base, and a fixed aw member opposing the movable jaw member and provided with a plurality of faces for attachment exchangeably to said base, whereby to present a vertical or a sloping face toward said movable jaw member, and means adapted to attach said fixed jaw member to said base in any of said positions.

2. A vise adapted to be used as a fiat vise or V-vise comprising a base, jaw moving means, a movable jaw adapted to be moved by said means suitably guided on the base, and afixed jaw member opposing the movablejaw and provided with a plurality of faces for attachment exchangeably to said base, whereby to present a vertical or a sloping face toward said movable jaw member, an auxiliary member for the fixed jaw adapted to be seated on one of its faces to form with said sloping face a V-shaped notch to receive round work, and means adapted to attach said fixed jaw member to said base in any of said positions.

3. A vise adapted to be used for round or flat objects comprising a base, fixed and movable jaws respectively adapted to be attached to and moved on said base, and means mounted on said base to move the movable jaw, one of said jaws comprising a member adapted to be turned in relation to the base and fastened in either direction, whereby to present a sloping or a vertical face, and an auxiliary member adapted to form with the sloping face thereof a V-shaped notch to receive round objects.

l. A vise having a base, a fixed jaw, and a movable jaw comprising an integral tubular guide member having therein a nut, and adapted to be guided by a bore in a bracket fast to said base, a screw in said nut having a bearing in said bracket, means adapted to prevent longitudinal motion of said screw, and means on said movable aw independent of said guide member adapted to hold the movable aw on said base.

5. A vise having a base and fixed and movable jaws, oneof said jaws being provided with an upper inwardly inclined auxiliary member adapted to be adjusted in a plurality of positions so as to hold a round object securely without projecting it into the path of a cutter or other tool working on the upper surface of the object held.

6. A vise for use with metal working machines having a removable chip-tray, said vise and said tray each comprising one member of an interlocking coupling adapted to connect the vise and chip-tray and to be readily disengaged, the upper surface of the tray when it is operatively positioned being exposed to receive chips formed duringv work on material held in the vise.

7. A metal working machine having therein a removable chip-tray adapted to receive metal chips formed by the operation of the machine, said tray comprising an open scoop having thereon means removably to interlock one edge of the tray under and so as to project it beyond a part of the machine upon which the chips are deposited as formed, whereby to expose the whole of its upper open face to receive oily chips thrown off incidental to the work of the machine, said tray having therein a strainer adapted to permit drainage of oil from the collecting chips.
