WILBUR F. BUDLONG, OF IBEREA, OHIO.

VISE OR CHUCK 0R LIKE MACHINE.

To all whom t may concern:

Be it known that I, l/VILBUR F. BUDLONG, citizen of the United States, residing at Berea, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vises or Chucks or Like Machines, of which the following is a specification.

This invention relates to improvements in a vise or chuck or like machines, and the invention consists in the construction substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a-plan view of the invention and Fig. 2 is a side elevation thereof showing the clamping jaws in working relation. Fig. 3 is a longitudinal sectional elevation showing the clamping jaws separated with the loose jaw retired. Fig. 4; is a front elevation as seen in Fig. 3. Fig. 5 is a cross section on a line corresponding substantially to -x, Fig. 3 and designed particularly to show a cross section of the base upon which the other parts are mounted. Fig. 6 is a detail showing the connection of the link with the screw head and adapted to be operated by lever L. Fig. 7 shows two views of the height and width gage arranged at the side of the machine.

The invention as thus shown represents a vise or chuck designed for use for all purposes where vises or chucks are used in machine work, and is adapted to combine with the adjustable jig features for the duplication of parts to be built on the interchangeable system. With slight change in form or of the form of the bed piece the device may be built for use on either drilling machine, milling machine, lathe, turret lathe, planer or shaper or other machines. As a whole the machine is designed to permit the quick and accurate placing of work to be operated upon, to securely hold each successive piece in the same relative position7 to accurately guide the operating tool in its work and to quickly and freely release the work when completed from the vise or chuck jaws and from all guides, stops and bushings. Having these objects and operations in view the machine has a bed piece or base B provided with a fixed jaw B, and opposite this on said base is the loose or slidable jaw C which has guide ribs 2 on its bottom running in longitudinal slots 8 in bed B and confined beneath by plates 4 lengthwise and screws Specification of Letters Patent.

5. The said jaw C is moved back and forth by means of the lever L as a handle and which also serves to tighten the work in the machine. Thus, the said lever has rounded bearing portions 6 between which the end of connecting link E is pivoted on transverse pin 7 Said pin is set eccentrically in said rounded bearings so that as the said lever is depressed it will operate with a drawing and clamping effect upon the said link and thus operate to bind the parts together as presently seen. The higher part of the eccentric or cam portions of said rounded bearings is opposite from the handle of the lever so that the movement of the lever L to a vertical position has the effect of releasing the tension on the connecting link E while the depression of the lever accentuates the tension. Said lever is pivotally connected with the head 8 of screw S. The said bearings 6 impinge against the rear rounded projection o of the slidable jaw C and operate to press said jaw inward by reason of the pull on link E by lever L. This occurs because the screw S is held at the front by nuts N and N bearing against stop P which is lowered over the screw in its notch or open slot 10 and bears against the nose l2 of t-he jaw to take the rearward pull on the screw. The said stop P is supported on a rod R running lengthwise beneath in the bottom of bed B and having a controlling handle H at its rear end by which said rod is axially rotated and stop P thrown in or out. The stop is out in Figs. 3 and i and in Figs.`1 and 2, and the open slot l0 is adapted to seat closely over the adjusting screw S so as to ta ke all pressure.

.In operation work YVV is placed between the jaws B and C, which, by reason of the conforming facings or, plates M on said jaws and the guide O is brought into its proper position. Then as the lever L is raised to a vertical position the jaw C is pushed forward firmly against the work and the nut N and lock nut N adjusted close against stop P and then the depression of lever L by reason of its ecoentrics causes the loose jaw to be pressed in firmly against the work. Locking of the work depends therefore at .least on these last agencies. Nut N serves to lock nut N, and these nuts with stop P can at the most ""only engage the parts together in a close but not in a clamped relation, but when adjusted and when the lever L is pulled down toward the horizontal position to make effective its eccentric action in its bearings 6 the work is securely locked within the jaws. On the other hand the work is released by simply raising the lever L to a vertical position, which releases the extreme tension caused by the eccentric action ot the lever and permits easy separation. The stop P is then thrown back by means of the lever H and this permits the drawing of the loose aw and screw S rearward and which carries the nuts N and N back beneath base B, Fig. 3. Pulling the lever L backward performs this withdrawal together with the withdrawal ot jaw C to the fullest extent, the stop lug 0, Fig. 3, being placed the proper distance back in the base to accomplish this end. This lug also serves as a guide and support for screw S. The ulcrum head 8 for screw S moves in a planed way between the bottom ribs Z7 of the base and which guide it in its travel. Pins 7 and 141 connect link E with lever L and screw head 8 respectively.

For the duplication or a continuous run of work of the same size and kind the jaws B and C are provided with removable tacings M secured to same by screws, pins or other devices. VThe said tacings are cast, machined or ground to conform to a portion of the surface of the piece or work to be operated upon and in such a manner as to permit the accurate 1and uniform placing of the piece or successive pieces. The piece or work is then laid oit and placed in the vise or chuck in the manner hereinbetore described and the same securely locked. In this connection I employ combination height and width gages having stepped rests or supports O, which are arranged at the sides of the machine and secured in position by means of slotted arms 17 and supporting rods 18. The tool T is then brought into correct position tor operation and the jaws of the vise or chuck are secured in cor responding position against the work. The tool is then raised from the work and the adjustable arms A for guiding the same are mounted on pivots 20 on the fixed jaw in this instance but may be mounted on the movable jaw, and hardened steel bushings or guides 22 are secured by screws, bolts or other means in said arms for said tool or tools. The said hardened steel guides are interchangeable and may be made in any suitable form for the guidance of the particular tool in use, such as round tor boring and tapping, rectangular for slotting and planing and other shapes for eccentric form. The graduated height and width guides or gages O are reversible on the rods 18, giving.

a wide range of height and width for work. They are adjustable sidewise or laterally by means of the rods 18 and lengthwise on the slotted arms 17, which are engaged at the side of jaw B by screws 19.

By means of stop P to throw against the front of the base B II obtain a iixed clamping abutment for nut N and at the same time I can throw said stop back when a slight release of the parts occurs and thus be able to open jaw C to the fullest extent and not be troubled with nuts or the like to eect such movement and without altering the position ot nuts N, N', thus adapting the machine to use on thev same size of stock or work indefinitely. A piece of work W is shown in Figs. 1 and 2.

B2 represents a cross bar which connects the ends of the bars A therewith by means of bolts b2 and 4both said cross-bar and said arms-are slotted for engagement by said bolts and adapted to rigidly fix said arms` to said bar when the proper adjustment has been effected.

A spring 15 is mounted upon pin 14 and engaged with link E and head 8 to constantly maintain the fixed angular relations shown, particularly when sliding adjustments are being made.
