PATENT OEEICE.

FITZGERALD VERITY DALTON, OF ST. NEOTS, ENGLAND.

SPECIFICATION forming part of Letters Patent No. 752,656, dated February 23, 1904.

Application filed January 14,1903.`

To a/ZZ whom it may con/067%:

Be it known that 'I, FITZGERALD VERITY DALTON, a subject of the King of England, residing at St. Neots, England, have invented certain new and useful Improvements in a Combined Lifting-Jack, Vise, and Drill, of which the following is a specification.

This invention relates to a combined tool which may serve the purpose of a lifting-jack, of a vise, or of a combined vise and drill.

The combined tool is more especially intended for the use of automobilists and users of agricultural machines.

In the drawings, Figure 1 is a side view.;

tool arranged as a lifting-jack. Fig. 3 is a front view, partly in section, illustrating the ample, a fence-rail. Fig. I is a front view of the said tool as a vise and drill. Fig. 5 is a plan of a detachable bail and chain.

The legs AA of the jack are pivoted to the cross-piece B at C C, so that they may occupy either of the positions shown in Figs. 2 and 4C, respectively. They are enlarged and perforated at D D to accommodate the screw E when used as a vise, as in Fig. 3. They are also curved at the ends, as at F, and provided with cross-heads, as at G, serving in one position as feet, Figs. l and 2, and in the other as clamping-facesFigs. 3 and 4.

L is a threaded boss removably held in the cross-piece B and provided with a iange L'. It may be prevented from revolving by a pin M or by a screw N.

` E is a screw similar to that of an ordinary screw-jack, but made hollow throughout, as in Fig. 2, to receive a spindle P, which carries the jack-head Q, which, however, has a socket-for example, a prismatic tapered recess-at R to receive different kinds of bits, a drill-chuck and the like, one of whichd namely, a drilling-bit--being illustrated at S in Fig. 4.

T represents, in Fig. L as an example, a piece of material held between the jaws ready to be drilled.

U represents any known kind of reversible ratchet-lever mechanism by means of which serai No. 139,077. (No man.)

i the screw E may be revolved in either direction, as in ordinary jacks.

The spindle P is carried, preferably, by a ball-bearing at V, and a removable collar W holds it in place. It has a squared end at X to receive, for example, a handle, as Y, to rotate the spindle when it is used as a drill or the like. This handle at other times lits in the hole V' of the ratchet mechanism.

H is a double hook or bail, and J a chain acting therewith as a bracelet, which may be pulled tight by the screw K. In Fig. 4 the clamping action of the vise is obtained by this bracelet. A more powerful vise is produced by removing vthe boss L and inserting screw E through the holes D, as shown in Fig. 3, and screwing it into the boss L. In conjunction with bracelet H J and a spanner used as a bar at Z the device may serve at the same time as a vise and be firmly fixed to any suitable fence-bar, such as shown at Z', or equivalent support.

The bracelet H K may be used to attach or assist to attach the vise' to a part of the motor-car or any other convenient support. To give even bearing to the flange O at the end of the screw E and to the iange L' of the boss L, the faces of the legs A Amay be rounded, as at A5, Fig. 3.

I do not conline myself to the exact construction of the parts illustrated and described; but

I claiml. In a lifting-jack, the combination of a jack screw, a cross-piece carrying a screwthreaded bush for said jack-screw, and legs pivoted to said cross-piece and movable toward and from each other, said legs being shaped to cooperate with one another as a vise.

2. In a lifting-jack, the combination of a jack screw, a cross piece carrying a screwthreaded bush for said jack-screw and legs pivoted to said cross piece and movable toward andfrom each other, said legs having their feet outwardly turned and ending in cross-heads and being movable each through a semicircle to coperate with one another as a v1se.

3. In a lifting-jack a hollow jack-screw in combination With a rotary spindle traversing said jack-screw, and adapted to receive adrill and means for revolving said rotary spindle.

4. In a lifting-jack, the combination of a jack screw a cross piece carrying a screwthreaded bush for said jack-screw, and legs pivoted to said cross piece and movable toward and from each other, said legs having perforations in them to cooperate with the removed jaek-serew and its threaded bush 'to force the legs toward each other to act as avise.

5. In a lifting-jack, the combination of a jack-screw, across-piece carrying a screwthreaded bush forsaid jack-screw, and legs pivoted to said cross-piece and movable toward and from each other, said legs having perforations in them to Cooperate With the removed jaek-serew and its threaded bush, to

force the legs toward each other to act as a vise, the legs having rounded faces A5 as and for the purpose set forth.
