COMBINED ANVIL, VISE, AND DRILL.

SPECIFICATION forming part of Letters Patent No. 624,910, dated May 16, 1899.

A lication filed August 23, 1898. $erial No. 689,365. (No model.)

T0 on whom it may concern.-

Be it known that 1, JAMES W. CONCHAR, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in a Combined Anvil,Vise, and Drill; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bench-Vises of a type combining the elements of a vise, anvil, and drill; and the object of this invention is to improve the construction of a tool of this kind so as to render it more convenient and eflicient than those hitherto produced.

The nature of the invention will fully appear in the description and claims following, reference being had to the accompanying drawings, in which Figure 1 is a view in perspective of a device embodying my invention, but without the anvil-jaw of the vise. Fig. 2 is a central longitudinal section of the drill attachment and the anvil-jaw of the vise, the other visejaw and the anvil being shown in dotted outline.

Similar letters of reference indicate corresponding parts.

In the drawings, A designates an anvil adapted to be bolted to a bench and to receive the stock B of the movable jaw 13 of a parallel-j aw vise. The internal construction is of a well-known type and need not be de scribed. In order that the entire face of the anvil may be used, the other vise-jaw B is removably attached to the anvil-block and is made adjustable thereon, so that larger or smaller work may be held in the vise with comparatively little movement of the visescrew 0. To secure this result, I provide the sides of the anvil,.near the top thereof, with a series of ribs A and on the inner faces of the downwardly-extending wings of the jaw B a corresponding series of recesses B into which the ribs of the anvil slide neatly when the vise-jaw is placed in position on top of the anvil. These ribs and recesses may be vertical, as shown in Fig. 1, but I prefer to incline them a little from front to rear downwardly, as shown in Fig. 2, so that the pressure brought to bear upon the vise tends to more firmly seat the removable jaw on the anvil and renders it practically as rigid as though cast integral therewith. This effect is still f urther increased by providing for but a comparatively narrowbearing of the jaw on the top of this vise and this toward the forwardpart of the jaw, as shown in Fig. 2, with a little clearance back of this rib B, so that instead of the front part of .the jaw being forced upwardly under pressure the rear part is forced downwardly in so far as the lateral ribs will allow.

It is to-be noted that the wings of the jaw 13 are made continuous outside the grooves and in practice are made strong enough to resist as much strain as-the jaw B without breaking. The ribs, however, are comparatively narrow, so that the jaw may be adjusted in short steps and do not project so far from the sides of the anvil asto specially interfere with its use as such.

In the end of the anvil is formed a serrated concavity A which with a similar recess in the inner face of the jaw B. This leaves the end of theanvil to project beyond the serrated jaw A so that the end of the anvil may be used for forming right-angled pieces, the

outer jaw being run out or entirely withdrawn for this purpose, and the pipe-jaws do not interfere with this operation. It is also to be noted that the corresponding pipe-jaws on the jaw B-serve as a strengthening-web to stiffen the main jaw.

The head-stock D of a drill attachment is made to hook over the movable jaw of the vise in a familiar way. The spindle D is mounted in a tubular bearing D which is threaded at one end, the screw engaging a similarly-threaded portion D of the headstock. At the other end the tube is provided with a hand-wheel D whereby the operator may feed the drill forward. In practice it is found that many drills are broken by using the coarse and powerful screw of the vise to feed up the drill, and this construction is designed to remedy this defect. A nut D takes the end thrust of the drill-spindle and pre- Vents its being turned back more than a limited distance.-

The tail-stock E of the drill is in the nature of an angle-plate to rest on top of the anvil and has wings E similar to those of the removable vise-jaw, excepting that a single rib E to engage the space between any two of the anvilribs is sufficient for each wing of the tailstock, as it is not subjected to the strain brought to bear on the vise. The vertical portion of the tail-stock is slotted at E and its sides serrated at E to take a similarly-serrated angle-plate D adjustably attached to the tail-stock by a bolt and thumb-screw E The angle-plate is useful in holding Work at any desired elevation, as illustrated by the piece of channel-iron F in Fig. 1.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of an anvil-block adapted to take the stock of a movable-vise-jaw, and having on each side a series of laterallyprojecting,upwardly-extending ribs terminating near the top of the anvil, a movable visejaw mounted in said anvil-block, and a removable vise-jaw adapted to rest on the top surface of the anvil, and having downwardlyextending wings to embrace said ribs laterally, and provided with recesses opening from the bottom of said wings and on the inner sides thereof, to receive said ribs, substantially as and for the purpose set forth.

2. The combination of a movable vise-jaw,

an anvil-block adapted to retain the stock thereof, and provided with a series of inclined lateral ribs at each side near the top of the anvil, and a removable vise-jaw having downwardly-extending wings adapted to embrace said ribs, and inclined recesses therein to receive said ribs, substantially as described.

3. The combination with a movable visejaw and a drill head-stock attached thereto, of an anvil-block adapted to receive the stock of the vise-j aw, and provided with lateral ribs in a vertical or slightly-inclined position, and a tail-stock having downwardly-extending wings with internal ribs to engage the ribs of the anvil-block, and an upwardly-extending body having a face perpendicular to the drillspindle, substantially as described.

4. The combination with an anvilblock having a series of lateral lugs near the upper face thereof extending in a slight angle downwardly and backwardly and a drill head-stock adapted to slide back and forth with respect thereto, of a drill tail-stock adapted for temporary attachment to the anvil-block, having downwardly-extending wings with inwardlyprojecting ribs corresponding to the angle of the anvil-lugs and having a drill-face perpendicular to the drill-spindle, a slot therein to receive a clamping-bolt, and angle-plate and a bolt and thumb-nut for adjustment of the same along the face of the tail-stock, a portion of both tail-stock and angle-plate being serrated for mutual engagement, substantially as described.

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

JAMES XV. CONCI-IAR.
