Specification of Letters Patent.

Patented July 19, 19211.

Application led April 18, 1918, Serial No. 229,240. Renewed May 27, 1921. Serial No. 473,047.

To all whom t may concern.'

Be it known that I, ALFRED S. MELLOR, a citizen of the United States, residing at Cambridge, county of Middlesex, State of Massachusetts, have invented an Improvement in'Vises, of which the following` de'- scription, in connection with the accompanying drawing, is a specification, like characters on the drawing representing,likeparts.

This invention relates to vises of that type which are used for holding work in a milling machine, planer, grindingmachine, etc., and the object of the invention is to provide a novel vise which is constructed so that the gripping pressure of the jaws on the work will tend to draw the work downwardly against the base of the vise, thus obviating any tendency of the work to rise in the jaw when it is clamped therein. Other objects of the invention are' to provide a novel vise of this type in which the jaws are provided with flat work-engagingw faces` and' which is so constructed that when the' work is clampedtherein, said faces have aslightA receding and downward movement while Other objects of the invention are to providea novel device which is so constructed thatthe operative' parts are 'protected 'from' dirt,` metal chips, etc., and otherwise to' improve vises, allas will be more fully herev inafter set forth.

ln order to give an understanding of my invention, I have illustratedincthe drawing a selected embodiment thereof which will now be described, after which the novel features will be pointed out 'in the appended claims. 1 I n Figure 1 is a plan view of avise embodying my invention;

Fig. 2 is a side view; Fig. 3 is an end view; y j, Y Fig. 1 is a section on the line 4 4," Fig. 3; Fig. 5 is 'a section on the line 5-5, Fig. 2; Fig. 6 is a; section on the line 6-6, Fig. 1.

The vise herein illustrated comprises a base 1 on which aresustained two jaws 2 and 3 which are4 movable toward and from each other therebyfto clamp the work between them. The jaw 3 is fixedly secured to the base 1 and constitutes the fixed jaw. The jaw 2 slides on the base land is provided with guiding-r members 4L which embrace the ribs .5"of ythe. base thereby retaining the movable jaw inits proper position.

For giving the movable jaw V2 its movement toward and `from the jaw 3, I have provided a 'combined cam andscrew mechanism so that by using the cam a quick adjustment of the jaw 2 can be made, while by using the screw a relatively slow but more accurate adjustment of said jaw can be made.

The screw for adjusting the jaw is shown at 6 and it extends longitudinally ofthe base and screw-threads into a sleeve-like nut 'Y which is connected to the jaw 2. This'nut '.7 is shown as havingn a post or stud 8 rising therefrom which enters a recess 9 formed` `in the jaw 2. The post 8 travels back and forth in a slot 10 formed in the base, and 1 guided by the base.

said nut is properly |The rotation of the screw 6, therefore,`\jvill tion of a wrench or implement for turning the screw. When the sleeve 11 is held stationary then the jaw 2'may be adjusted by applying a wrench to the wrench-socket 14 and turning the screw 6 in one directionv or the' other, said screw being held from longii tudinal movement by the sleeve 11.

A cam device is provided for moving the sleeve 11 bodily in a. direction longitudinally of the screw thereby giving a quick adjustment to the movable jaw 2. Such cam device comprises a cam member 15 which operates between two stationary shoes 16 and which is pivotally mounted on a `stud17 rising from the sleeve 11. By turning fthe cam between the stationary shoes A16, the' sleeve 11 will thus be bodily shifted in one direction or the other. The shoes'lG are each confined in a cam-receiving chamber1S" formed in a housing 19, each shoe having a stud or stem 20 extending therefrom lwhich enters a recess in the wall ofthe housingthereby holding the shoe in proper position. The cam 15 is turned by means of a,` handle 21 which is connected to the postfl? for turning movement and which is provided with a pin 22 that extends into an handle tothe cam and as the handle and 'cam l turn about the same axis,'turning movement of the handlewill thereby turn the cam:

The handle 21 is provided with a cover plate 23 which overlies the top of the housing 19 and forms a cover or closure for the camreceiving chamber 18. Thiscover prevents Y any dirt or metal chips from entering the cam-receiving chamber.

The jaws 2 and 3 are each provided with a work-clamping member which is yieldable rearwardly and downwardly so that when work is clamped between said jaws, the clampin'g pressure will cause the. workc'lamping members to yield rearwardly and downwardly thereby tending to draw the work `down against the base 1 and resisting any` tendency o-f the-work to be forced out of the jaws by the clamping pressure. These workclamping members are indicated at 24 and V25, respectively. Each. work-clamping member is provided with a flat workengaging face 26 which normally projects slightly beyond the vertical face of the cor'- responding jaw, and said members are so sustained onthe jaws 2 and 3 as to permit l them to yield rearwardly and downwardly in such a manner that the faces 26 will always remain in .their parallel relation'dur'- ing the yielding movement. Each workclamping member is secured to a head 27 provided with a stem or guiding elementY 28 which has a downwardly-inclined position and which enters and is guided in an aperture 29 formed in the jaw. The stem 28 extends rearwardly from the central portion of the head, as seen in Fig. 5. Situated on either side of the stem is a spring 30 which is confined in a socket 31 inthe jaw and vwhich acts against a follower 32 that in turn impinges against the head 27.

- Vficient dimensions to permit movement ofthe work-clamping ,members relative to the jaws. The heads 27 are received in recesses vformed inthe'jaws, `and the walls of the Arecesses are arranged in parallelism with the stem 28 so that when each work-clamping member is forced rearwardly by the clamping pressure of the work, said member willmove in a downwardly-inclined position. During this movement the workclam'ping face 26 will maintain Vits vertical'or parallel relation. j

The operation of the device'will be readily apparent from the foregoing. Nor- ,mally'the springs 30 hold the'work-clamping members in their 'forward positionwith the faces 26 projecting slightly beyond the faces of the jaws. When work is clamped between the jaws by the operation of either the cam or; the screw, the clamping pressure of the work will tend to force the work- Vclamping members rearwardly and downs wardly against the action of the springs 30, and thefdownward component of suchv receding `movement of the work-clamping members will operate to' hold theV work firmly against the base.

The construction of the vise is such. that the screw 6 is entirely protected from dirt and chips. Moreover, the plates 34 are o-f Va size to completely closethe ends of the recesses in which the heads 27 are received so that said plates constitute a protection against the entrance of any dirt'for metal chips between the work-clamping members and the jaws. The device is relatively simple to manufacture and is effective in firmly holding the work.

I claim:

1. In a vise, the combination with two jaws, of means to move them toward and from each other, each jaw having a recess in its operative face, the top and bottom walls of which recess have a downwardlya inclined direction, Va work-clamping member fitting the recess in each jaw and constructed to move baclrwardly and..down wardly when pressure is applied thereto in a direction determined by thel top and bottom walls of the recess, a guidingV element i l rigid with each work-clamping member and extending rearwardly and downwardly therefrom through the( correspondingjaw,
