BENCH-VISE.

Specification of Letters Patent.

Patented Nov. 21, 1905.

To cbll'wwm, it may concern:

Be it known that I, CHARLES HANIMANN, a citizen of the United States, residing at Flushing, in the county of Queens and State of New York, have invented certain new and useful Improvements in Bench -Vises, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings and to the reference characters marked thereon.

My present invention has relation to vises such as are employed by mechanics and others and intended to hold articles or materials while they are being worked upon. These vises are usually attached to-some iixed sup port, as a bench or table, and they are ordinarily known as bench-vises. Of these bench-vises there are many varieties suitable for holding different kinds of work and operative in different ways, and it is chiefly to a variety now come to be commonly known as swivel-bottom vises that my invention is principally applicable, although some of the features are equally applicable in connection with other varieties,as will hereinafter appear.

The principal object of my invention is to provide or produce a swivel-bottom or turning vise wherein the clamping` or setting of the vise-body at the desired point upon the base may be conveniently and securely accomplished by the act of turning the vise-screw, the base being grasped by the holding mechanism on opposite sides of the exterior of the cylindrical part on which the vise-body turns, thereby affording an extensible leverage for the holding mechanism against any disturbing action, the parts being simple, cheap, and

easy to make and effective in action or results.

A subordinate object is to provide means for easily setting the clamping mechanism so that it will not clamp the base, but will leave the vise-body free to be turned on its base whenever so desired.

Another object of the invention is to provide a simple, cheap, and effective means for locking and holding a turning or adjustable back jaw of a vise accurately and securely in position parallel with the front jaw when it is intended that the former shall remain stationary with respect to the latter.

To accomplish the foregoing objects and to secure other and further advantages in the matters of construction, operation, application, and use, my improvements involve certain new and useful peculiarities of construction, relative arrangements or combinations of parts, and principles of operation, as will be herein first fully described and then pointed out in the claims.

ln the accompanying drawings, forming part of this specification, I have shown my improvements as applied in connection with a particular form of bench-vise which is ordinarily called a smiths vise or cmetalworkers vise; but it should be understood that this selection is only for convenience of illustration and that my improvements are equally applicable in connection with any other variety of bench-vise.

Figure l is a vertical view, partly in section and partly in elevation, on a plane through the axis of the vise-screw, showing my improvements applied in connection with a swivel-bottom vise, wherein a rack and dog or pawl are employed for operation in conjunction with the screw-shaft in order to force or release the slide-bar. Fig. 2 is a horizontal view, partly in plan and partly in section, showing the base and the means employed for securing the vise-body thereon so as to turn upon the exterior thereof and means for freeing the clamping mechanism. Fig, 3 is a plan of a separate piece employed in connection with the rear of the vise-body and the base, the same being detached from the other parts.l Fig. 4 is a central vertical section and elevation corresponding with Fig. 3. Fig. 5 is a vertical view, partly in section and partly in elevation, showing the base and a fragment of the vise-body applied thereon, the view being taken on a plane through the axis of an adjustable clamp applied in connection with the viseebody. Fig. 6 is a sectional elevation on a scale enlarged beyond Fig. 5, showing the' adjustable cla-mp represented in that figure. Fig. 7 is a side view and partial section of the rack shown in Fig. l, the same being detached.

Fig. 8 is a horizontal section and plan View on a plane through the axis of the screw-setter for the swiveled or movable jaw of the vise. Fig. 9 is an elevation on a smaller scale, showing the plate by which the screw-setter for the .movable jaw is held in working position in connection with the vise-body. Fig. l0 is a view, partly in section and partly in elevation, corresponding with Fig. l, except that a nut within the vise-body is employed to receive the vise-screw and to cause the move- IOO IOS

ments of the slide-bar and the vise-head, connected therewith directly'through the medium of the vise-screw and operating to clamp the base at one part. Fig. 11 is a view in crosssection illustrating the manner of mounting the nut shown in Fig. l0 in the vise-body, and Fig. 12 is a side view of the nut detached.

In all the figures like letters of reference wherever they occur indicate corresponding parts.

The vise shown in Fig. 1 is of the rapidtransit or quick-action variety-that is, it is arranged so that when the screw-shaft A is turned in one direction the dog or pawl a will be engaged with the rack B and the slide-bar carrying the movable head C then forced in a direction to close the head C toward the stationary7 head D, and when the screw-shaft is turned in the opposite direction the dog or pawl a will rise out of engagement with the rack, and thus leave the slide-bar free to be quickly moved back and forth for rapid adjustment without the necessity of turning the screw. This in itself is an old form of construction or arrangement and is not an essential part of my present invention, although it or any other form of connection between the slide-bar, the vise-body, and the screw-shaft maybe adopted. For instance, in Fig. 1() the screw-shaft A engages with a nut B, applied in connection with the vise-bod y, and the slidebar is to be slowly moved in either direction by the turning of the screw-shaft. The rack or the nut equally receives the thrust of the vise-screw.

E represents the base on which the visebody is mounted and which is intended to be secured to a bench or table or other support in any suitable way or by any suitable means. The vise-body is mounted so as to turn upon the exterior of this base and so arranged` and connected with the base that whenever the vise-jaws are tightly closed together or forced against a piece of work or material between them the vise-body will become effectually clamped at opposite parts against the outside of the stationary base, thereby being held securely in the position where thus clamped in order to prevent movement upon the base while the vise is in use. As soon as the visejaw or vise-screw is loosened after the parts have been clamped the vise-body will be free to turn unless set or fixed in place by separate and independent means, which separate and independent means are provided for use in case it be desired to so set the vise-body.

To make the automatic clamping rigid and secure, I provide the base with an annular recess 7) around its exterior, and I supply the front part of the vise-body with a corresponding annular ledge c, reaching about half the circumference of the circle and adapted to fit closely in the recess When the rack is employed to receive the th rust of the vise-screw, I supply the same with a depending portion d, having an inwardly projecting ledge e, also calculated to move in the recess This rack is adjusted in the body of the vise from the rear and is secured in place by a suitable screw-bolt or other equivalent means, as f, the same permitting a very slight movement of the rack in its seat for reasons to'be hereinafter explained.

When a nut B is employed to take the thrust of the vise-screw, it is mounted in the vise-body in a manner similar to the mounting of the rack and it is supplied with a depending portion, as CZ, having an inner ledge e', also adapted to fit in the recess b, and the nut is secured in place by a screw-bolt, as f, or by equivalent means, this fastening permitting a very slight movement of the nut on its seat, the same as provided for in the case of the screw-rack.

At the rear of the vise the body is extended, as at g g, and upon this extension is secured a curved piece, as F, having a ledge c2, also calculated to lit in the recess b. This piece F is secured in place by suitable screws or bolts, as at the points /L z, and when in place it operates for one purpose to extend or lengthen the bearings in the recess opposite the front of the vise. This piece F is employed equally when a rack or a nut is used.

The parts being constructed as so far explained, it will be apparent that when the vise-screw is turned in the direction to move one jaw toward the other the front bearing part of the vise-body will be forcibly crowded to its seating on the outside of one part of the base and the rack or the nut forcibly clamped against the outside of the opposite part of the base, thereby efect-ually clamping and holding the vise-body at the point at which the clamping of the work takes place. The clamping being effected upon the exterior of the base, a long leverage is afforded for resistance to any possible turning action of the vise-body by reason of which the clamping is made entirely effective and not liable to slip or give way under any ordinary circumstances of use.

The clamping is automatically effected, as will be observed, and the opposite turning of the vise-screw will loosen the parts sufiiciently so that the vise-bod y may then be easily turned on its seat on the base. At times it may be desired that this automatic clamping of the vise-body shall not be effected, and I therefore provide means by which it may be prevented. As previously explained, the rack or the nut is capable of a Very small movement on its seat in the vise-body. Through the piece F, I pass a suitable screw-bolt, as ri, and this enters and engages the depending portion of the rack B orthe nut B', as the case may be. By turning this screw in the proper' direction the rack or the nut is drawn toward the piece F through a very slight distance, suiiicient, however, to yprevent clamping against the base-piece in connection with the front part of the vise-body. By this means the parts may be so adjusted and set that the automatic clamping will not be effected, or after the clamping has been effected the parts may be loosened, so that the visebody may be easily turned on its base, if so required, and without disturbing the visescrew. To provide means independent of the vise-screw for setting or fixing the vise-body at any desired point on its base, I supply the upper part of the base with a series of teeth or serrations, as at and on the front part of the vise-body and at a convenient point I provide a socket, as G, which receives a screw G', on the lower end of which is mount# ed a loose block G2, having teeth or serrations adapted to engage with or interlock with those at 70. When the screw Gr is turned up, the visesbody, if otherwise free to be turned on its base, is in no mannerinterfered with; but when the screw G is turned down the vise-body will be set, and this setting may take place at any point of the circular travel of the vise on its base. This particular means of setting the vise-body is only employed as an example, it in itself being old, and it may be replaced by any other equivalent means for accomplishing the setting.

The back jaw D is of the swiveled varietythat is, it is mounted on the vise-body so that it may turn to accommodate itself to the side of any inclined or irregular piece of work or material; but the swiveled jaw is not necessarily employed in connection with a vise structure arranged to be clamped upon its base after the manner of my invention, as above explained. Manifestly a solid back jaw might be employed in connection-with that construction, if so desired. However, when the swiveled jaw is employed it is sometimes desirable to fix it securely in a position with its face parallel with that of the frontjaw, so that it will not yield in either direction when any article is clamped between the two jaws.

D is a depending portion of the vise-jaw D, which rides in a recess in the upper part and at the back of the vise-body. In connection with this depending portion D', I employ a screw D2,which enters a recess in the part D. This screw passes through an opening provided for it at the back of the vise-body, and it has a conical projection D3, which fits a conical recess in the opening through the back of the vise-body. rIhe conical projection D3 is of such length that when the screw D2 is completel y unturned to release the depending portion D then the conical portion and the threaded end of the screw will be located in the opening through the vise-body, leaving the vise-jaw free toturn upon its seat in the manner then' intended. Vhen the screw D2 is turned in in the manner shown in the drawin the conical recess provided for its reception,

and therefore prevents the screw from moving in its seat, and consequently prevents the vise-jaw from 'moving in any degree. The construction and arrangement being substantially as indicated, the swiveled jaw may be rigidly set at the desired point and released whenever required. rIhe screw D2 is pre vented from becoming dislodged by the application to the exterior of the vise-body of a recessed plate D4, which is screwed in place, as indicated, or secured in any other desirable manner.

c The improvements, being constructed and arranged for operation substantially in accordance with the foregoing explanations, will be found to admirably answer all the purposes or objects of the invention hereinbefore alluded to.

Having now fully described my invention, what I claim as new herein, and desire to secure by Letters Patent, is-
