SPECIFICATION forming part of Letters Patent No. 403,107, dated May 14, 1889.

Application filed .Tune 25, 1887. Serial No. 242,445. (No model.)

To all whom it may concern:

Be it known that I, BIRDSILL HOLLY, of Lockport, in the county of Niagara and State of New York, have invented new and useful Improvements in Vises, of which the following is a specification.

This improved vise is a bench-vise which is designed both for metallic and wood Work. The vise proper consists of a hollow supporting-mandrel and a second hollow sliding mandrel iitting in and sliding' within the supporting-mandrel. The two mandrels carry a series of jaws for different kinds of work, arranged radially around the mandrels. The sliding mandrel is operated by a shaft screw-threaded at one end, which extends through the sliding mandrel and screws into a nut fixed to the supporting-mandrel. The supportingmandrel is held in a holder of peculiar construction, which is bolted or otherwise permanently fixed to the bench, preferably to one corner thereof. This holder is what may be appropriately termed a three-way holder, since with it the supporting-mandrel may be se'- curely and rigidly held in either a vertical position or in two horizontal positions at right angles to each other. The supportingmandrel is held from turning` in the holder by means of a set-screw, which also enables it to be adjusted vertically. The supporting-man-- drel is further held from rotation when the vise is employed for heavy work by interlocking teet-h carried by the mandrel and holder, respectively. One pair of the holdingjaws is provided with circular bores or aper- .tures in each jaw, which may serve as bearings for a removable drill or for holding other tools employed by the carpenter or machinist.

The vise is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the vise when the same is in a vertical position, showing a drill mounted therein. Fig. 2 is a central vertical section thereof, partly in a plane indicated by the line 2 2 in Figs. 1 and 5, and partly in a plane at right angles thereto, as indicated by the line 2 2 in Fig. 1i. Fig. 3 is a side elevation of the vise when the same is in a horizontal position, in which a pair of pipe-holding jaws replaces the drill. Fig. i is a cross-section in a plane indicated by the line 4 4 in Fig. 1. Fig. 5 is a cross-section in a plane indicated by the line 5 5 in Fig. 1. Fig. 6 isa detail View of the three-way holder, and Fig. 7 is a detail view of the pipe-holding jaws.

A is a portion of a carpenters or other bench, to one corner of which the three-way holder B is securely attached. This holder is a skeleton frame, having six preferably circular apertures C C, oppositely arranged in pairs on the six sides of the holder, so that an axial line through the center of` one pair of apertures shall be perpendicular to axial lines through the centers of the other two pairs, the three axes having a common center. The bench is formed with an aperture, D, immediately beneath the aperture in the bottom of the holder.

E is the hollow supporting-mandrel, preferably circular in cross-section. This supporting-mandrel is held by the three-way holder, and may be placed ltherein through any opposite pair of the apertures C C. This mandrel fits nicely and closely in the apertures C C, so that it can have no lateral movement therein. Since the apertures and mandrel are both preferably circular, the mandrel is held from rotation in the holder by a setscrew, F, tapped through one wall of the holder, and which bears against the outer surface of the mandrel. This setscrew also holds the mandrel at any height to which it may be vertically adjusted in the holder to suit the user or the character of work employed. This set-screw is so mounted in the holder that its axes if continued would pass through the common center of the three axial lines passing through the centers of the six apertures in the holder. Thisis an important feature, since in whatever position the mandrel maybe placed the set-screw will act upon it with equal efciency, and hence only one set-screw need be employed. At one end this supporting-mandrel is provided with radial jaws G H I J, preferably formed integrally therewith and with their faces perpendicular to the axis of the mandrel. The bore of this mandrel extends axially throughout its length; but at the other end from the jaws the bore is contracted in diameter and internally screw-threaded to constitute a nut, L.

Fitting and sliding within the bore of the fixed mandrel is the slidingmandrel M, which is slightly less in length than the fixed mandrel. This sliding mandrel carries on its outer end radial jaws G II I J, corresponding with the fixed jaws on the fixed mandrel, with their faces opposed to and parallel with the faces of the fixed jaws. The sliding mandrel is also provided with a longitudinal axial bore, through which passes the operatin0-sl1aft N. This shaft at its outer end is provided with an enlarged head, which forms a shoulder, a, to prevent the shaft slipping through the bore of the sliding mandrel, and with an operatinghandle of usual construction. The shaft at its other end extends beyond the sliding mandrel, and this extension is screw-threaded to fit in and co-operate with the nut L on the support ing or fixed mandrel. Screw threaded nuts or washers l) l) are screwed on the shaft against the inner end of the sliding mandrel to prevent any longitudinal movement of the shaft in the sliding mandrel and to compel the sliding mandrel to slide in and out when the shaft is turned. Since the bore of the fixed mandrel and the sliding mandrel are preferably circular, the sliding mandrel is prevented from rotation within the fixed mandrel by means of a removable nut, c, attached to the exterior of the sliding` mandrel, which slides in a longitudinal slot, d, in the fixed mandrel.

By means of the radial arrangement of the jaws four pairs of jaws are provided, which are constructed to be adapted to different kinds of work. The jaws G are formed with broad faces to adapt them to hold wood-work and constitute a woodvise. The jaws H, opposite the jaws G, are narrow and furnished with steel faces e c to adapt them to metalwork and constitute an iron-vise. Between the jaws G II on one side are small jaws I for light work, which constitute a bracket-vise. Opposite the jaws I is a fourth. pair of jaws, J. This fourth pair of jaws may be conveniently used in conjunction with the woodjaws G to give a more extended bearing-surface fol long work; but their principal use is as hangers for the attachment of other tools. For this purpose each jaw is provided with a circular bore, f, the axes of which are parallel with that of the mandrel.

In Figs. l and 2 the jaws K are shown as hangers for a drill-shaft, O, carrying a drill, P. The bore fof the movable jaw or hanger .I has a smaller diameter than the bore in the fixed jaw, so that the drill-shaft is inserted in position by passing it through the fixed jaw. The drill-shaft throughout the greater portion of its length is of a diameter to fit nicely in the bore of the fixed jaw; but its outer end is contracted, forming a shoulder at g, so as to fit in the bore of the sliding jaw. The extreme outer end of the shaftis screw-threaded, and when the shaft is in position, with the shoulder g abutting against the face of the sliding jaw, the screw-threaded end projects beyond the sliding jaw, and to this end an operating crank-handle, Q, is screwed. The handle an d shoulder g prevent the drill-shaft sliding in its bearings.

R is a removable and adjustable collar slipping over the nut end of the outer fixed mandrel, being held in any desirable position by a set-screw 71., and it carries the drill plate or plates S, which hold the work operated upon by the drill. the drilling progresses, the drill is advanced by adjusting the sliding mandrel by means of the operating sorenshaft.

In Fig. 3 thedrill is replaced by a pair of pipe-jaws, T T, which have screw-threaded holding-Shanks 1T, which pass through the bores ff, and are held in position by nuts m m. Other tools may in a similar manner be attached to the vise.

fhen the vise is used in a horizontal position, as in Fig. 3, and is employed on exceptionally heavy work held near one end, the setscrew F may and sometimes does prove insufficient to hold the supporting mandrel fixedly in position; hence one at least of the vertical faces of the holder is provided with a series of fixed teeth or cogs t t, which are engaged by corresponding cogs, w fw, on the outer mandrel. These lock the mandrel and hold the same from rotation.

Not only does the capability of the quick and ready adjustment of the vise to horizontal or vertical positions to and away from the bench and the raising and lowering of the same, in all of which positions it may be fixedly and securely held, render the vise in itself applicable to all kinds of work, but different sides of the same work under treatment may be operated on. without removing the work from the jaws by simply unloosening the set-screw F and rotating the vise if it is in a vertical position, or by reversing its position from right to left (or vice versa) if in a horizontal position.

I claim as my invention- 1. The fixed holder formed, as described, to hold the fixed portion of a vise in either a horizontal or a vertical position, in combination with the fixed portion of the vise and the sliding portion carried by said fixed portion, substantially as set forth.

2. The fixed three-way holder provided with holding-apertures on its six sides, in combination with a vise constructed, as described, so that it may be held in any opposite pair of said apertures, substantially as set forth.

3. The fixed three-way holder provided with holding-apertures on it-s six sides and a vise which may be inserted in any opposite pair of said apertures, in combination with a setscrew carried by said holder and bearing against said vise, the axis of said screw being substantially in line with the center of the holder, substantially set forth.

4. A vise having four fixed jaws extending radially at right angles to each other, in combination with four movable jaws extending radially at right angles to each other and IOO IIO

jaws, one of each mandrel formed with oppositely-arranged bores or apertures, and a drill having a bearing in the apertured jaw of the sliding mandrel, whereby it may be advanced by movement of said mandrel, and the shank of said drill extending through the aperture in the jaw of the fixed mandrel, in combination with a removable and adjustable drill-plate supported bythe fixed mandrel, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
