ANGUS A. MCKENZIE, OF CAMBRIDGE, MASSACHUSETTS.

QUICK-ACTING- VISE.

Application filed December 16, 1915.

To all whom it may concern Be it known that 1, Arrow A. MoKnN /an, a citizen of the United States, and resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Quick- Acting Vises, of which the following is a specification, reference being had to the accompanying drawings.

This invention has for its object to provide a vise having one stationary and one movable jaw, the latter jaw being adapted to be quickly closed and opened and se curely locked with said vise when closed, said movable jaw being preferably adapted to be used with the type of folding vise shown in my patent issued August 31, 1915, and numbered 1,157,959, on a portable hand vise, and being specially adapted for the use of carpenters and other mechanics.

The invention consists in the improvements whichI will now proceed to describe and claim.

Of the accompanying two sheets of drawings, forming part of this specification Figure 1, represents a perspective view of a vise embodying my invention, the same being shown open and ready to receive'the material which is to be held in the vise. Fig. 2, represents a side view of the movable jaw. Fig. 3, represents a view taken on line 3-3 in Fig. 1, looking in the direction of the arrows, showing the rear view of the movable jaw as applied to the vise. Fig. i, represents a diagrammatic view, similar to that shown in Fig. 2, with the parts of the jaw disassociated for showing the relative construction of the same. Fig. 5, represents a perspective view of the forked-locking lever, shown in Fig. 1, showing the cam-shaped peripheries of the hubs of the lever. Fig. 6 represents a side view of the movable-jaw-plate operating lever. Fig. 7, represents a plan view of the movable jaw of the vise. Fig. 8, represents a left-hand view of Fig. 7. Fig. 9, represents a view taken on line 99 in Fig. 7 looking in the direction of the arrows, showing the anchoring member of the movable jaw. Fig. 10, represents a plan view of the sliding and supporting plate of the anchoring member shown in Fig. 9, the levers and the looking hanger member being removed therefrom. Fig. 11, represents an end view of the locking hanger used on the anchoring member of the movable jaw, Fig. 12,

represents a sectional view taken on linen 12-12 in Fig. 8, looking in the direction of the arrows, showing the movable jaw closed upon a piece of material. Fig. 13, represents the same view as Fig. 12, but shows the movable'jaw open with the material freed therefrom. Fig. 14:, represents a perspective view showing a modified construction for the frame member, the bottom edge of which is provided with teeth, or other serrations or roughening, as against the plain surface shown in the other views of the drawing, for affording the locking jaws of the anchoring member a means for preventing slipping along the frame of the vise when the jaw is in locked position therewith. Fig. 15, represents a perspective view of one of the ends of the locking hanger member shown in Fig. 11, which may also be provided with teeth, or other such serrations or roughening, for engaging either with the plain frame edge shown in the drawings, or with the type of locking edge shown in Fig. 14.

The same reference numbers indicate the same or similar parts in all the views, and the term movable aw refers to the entire mechanism of the working jaw of the vise as a unit.

The numeral 1, in its entirety, represents a rigid frame member which is preferably provided with a stationary jaw 2 on one end and the parallel runs 3 and 4: upon which the movable jaw member rides, which runs 3 and 1 are provided with the top surfaces 5 and 6, the

lower surfaces

runs

12 and 13, and isadapted to rest upon the top surfaces 5 and 6 between the

sides

9 and 10 of the runs 3 and 4:. The guide-plate l1 isalso provided with the supporting

lugs

14 and 15 which project upwardly from the plate and are provided with the

transverse'drilled holes

16 and 17, within which is supported the supporting-shaft 18, which shaft is preferably provided with the cotter-pins 19 for holding the same secured in set position. The guideplate 11 is also provided on the side 20 with the web 21 having the boss 22 which has the tapped hole 23 within which is secured the adjustable tension-springstud 24 which holds the tension spring 25 in working po- 7 and ,8, of the runs 3 the opening 26 in the top of the same be: tWeen the

47 is a toothed, knurled, or otherwise locking-

jaws

30 and 31 of the locking hanger member 27.

48 is a modified type of locking-jaw for the locking hanger member 27 ,and is provided with the rough or toothed surface 49,

for engaging with the surface 47 shown in Fig. 14, for overcoming any tendency of slipping on the part, of the anchoring member when the same has once been locked in the anchoring position.

Having thus described the parts of my invention in detail, the manner in which the same is assembled and operated is as follows: The movable-jaw-plate 36 is first set upon the runs of the viseby being posi tioned diagonally across the same, which permits the guiding-

lugs

42 and 43 to engage with the

surfaces

7 and 8 of the runs of the vise as the movable-jaw-plate 36' is brought into the parallel position with the stationary jaw 2 of the vise. With the supporting-shaft 18 removed from the guideplate 11, the plate is set into engaging posivtion with the runs of the vise, as shown in Fig. 1. The fioatinglocking member 27 is then associated with the guide-plate 11 and the runs of the vlseby insertingthe head member 29 through the opening 26 of the V guide-plate 11 form the underside thereof.

The forked-anchoring-lever 32 is then engaged with. the floating locking member 27, as shown in Figs. 7 and 9, the hub of said lever 32 being set adjacent to the supporting-lug 16 of the guide-plate 11 with the hole 34 in line with the hole 16 in the supporting-lug 14. The movable-jawplate-operating-lever is then set adjacent to said forked lever, with the hole 37 in line with the hole 34 of the forked lever. The supporting-shaft 18 is then inserted through V the holes in the supporting-

lugs

14 and 15,

the hole 34 of the forked lever, the hole 28 of the hanger locking member 27 and the hole 35 of the movable-j aw-plate operating lever 35 for supporting said levers and said hanger member in operating position with said guide-plate. The supporting-shaft 18 is then preferably pinned in position by means of the cotter-pins 19 on the ends of the same. The tension coupling spring 25 is then set to engage with the movable-jawplate 36, as shown in Fig. 8, and is supported intoset engaging position by means of the tension sprlng supporting and ad usting-stud 24 which is adjustably secured, as

shown in Figs. 10, 12 and 13, to theguideplate 11, by being'screwed in the hole 23 which is specially provided therefor. It may be observed that the tension between the spring which engages the clamping movable-jaw-plate 36 with the anchoring member ofthe vise, may be varied to suit accordi ing as may be desired,-sufiicient clearance between the spring and the boss 22, as shown in Fig. 10, being always required for permitting the play necessary between the anchoring member of the vise and the clamping and working jaw of the same. It may be observed that the cam member 35 of the movable-jaw-plate operating lever '35 en- To slide the movable jaw'to any part of the vise, the same may be accomplished by raising the

levers

32 and 35 into their upward positions, as shown in Figs. 1 and 2, which permits thelocking jaws 30. and 31 of the hanger locking member 27 to drop downward and sufficiently'away from the surfaces 7-and-8of the runs3 and4, respectively, to

lot

' gages with the cam-lug 39 of the movable- 9 jaw-plate 36, as shown in Figs. 7 and 12.110

permit the same toclear said runs, thus;

leaving the anchoring member of the vise free to sllde along the runs of the same. To

engage the movable-jaw-plate for clamping a piece of material 44in the vise, the movablejaw member is preferably brought near to, but not engaging with, thematerial, as shown in Fig. 13, when the anchoring lever 32 may be lowered into the locking position, which lever, by virtue of the action of the cam-shaped hubs33 engaging with the heads 29 of the hanger locking member 27, raises the hanger locking member 27, and consequently brings the locking-

jaws

30 and 31 of the same into gripping contact with the

lower surfaces

7 and 8 of the runs 3 and l, respectively, thereby gripping and loclr ing the anchoring member therewith. The movableplate-jaw operating lever 35 may then be lowered, as shown in Fig. 12, which results in bringing the cam 35 into working contact with the camlug 39 of the movablejaw-plate 36, and thus forces the same against the tension of the coupling spring 25 to engage with the material M, and grips and clamps the same between the stationary jaw 2 and the movable jaw of the vise; thus closing the working jaw of the vise on the material, as shown in Fig. 12. To open the jaw for releasing the material, the lever 35 is swung in the upward position, as shown in Fig. 13, which allows the movable-jawplate 36 to automatically free itself from the material by the action of the coupling spring forcing the movable-jaw-plate back to the original position with the anchoring member. The material is thus freed between the jaws of the vise and may then be removed from the same.

It may be observed that the anchoring member of the vise may be locked with the runs of the same by, applying the proper pressure to the lever 32 downward, which brings the cam section of the same into working engagement with the supporting head 29 of the locking plate, and the farther the lever 32 is forced downward, the greater is the action of the cam and the greater is the gripping power between the locking

jaws

30 and 31 and the guide-plate 11 upon the runs 3 and a between them,-the incline of the cam 33. increasing as the lever is ad vanced in the downward position. It may also be observed that as the movable-jawplate operating lever 35 is advanced in the lower position, that the incline of the cam member increases, and thus allows the proper gripping pressure on the movablejaw-plate 36 necessary for holding the material in clamped position between the jaws of the vise. Thus it must be understood that the design and construction of the combination of the floating working jaw and the anchoring member of the movable jaw of the vise permits of the application of extra gripping power after the anchoring member has been locked into position with the frame of the vise, and also furnishes a quick acting vise, in that the operation of the same is very simple and effective, the movable jaw permitting of opening and closing rapidly and positioning readily in working relation, or otherwise on the vise.

It may be understood that where the vise is to be used by an operator for the handling of standard sizes of articles or material, that by once setting the anchoring member of the vise in proper relationship with the particular dimensions of the article or material, that the operator may confine himself to the manipulation of the movable-jaw-plate operating lever 35, as shown in Figs. 12- and 13, without resetting the anchoring member. it may further be observed that the construction of the movable jaw permits of a powerful gripping feature which may be applied to the article or material held in the vise according as may be required by the operator. It may also be observed that by raising the movable-jimplate operating lever into the upward position, where no great pressure is required to grip the material held in the vise, that by simply forcing the guide member 11 as far as it will go, toward the material to be gripped, and locking the anchoring member by lowering the anchoring lever 32, that the material will be suiliciently gripped for ordinary purposes between the jaws of the vise, since, as shown in Fig. 13, the movablejaw-plate 36, when in the normal position with the operating lever upward, sets ad jacent to the guide member 11; so that it will appear that it is not always necessary to manipulate the movable-jaw-plate operating lever 35 for completing the gripping operation of the movable jaw of the vise.

It may be understood that a vise, such as I have'herein disclosed, is a very useful apparatus for carpenters, especially more particularly for use in their finishing work, and where it is required to provide greater gripping force upon the material held in the vise, the modified gripping runs, shown in Fig. 14, and the modified gripping jaw shown in Fig. 15, may be used to advantage for positivelv preventing slipping on the part of the anchoring member when the same has once become locked in the working position and further pressure is'applied to the floating jaw of the vise by the manipulation of the movable-jaw-plate operating lever 35, in the downward direction.

While the preferred embodiments of my invention have been described in detail, it will be understood that I do not wish to be limited to the particular construction set forth, since various changes in the form, material, proportions, and arrangement of parts and in the details of construction may be resorted to without departing from the spirit and scope of the invention, or forfeiting any of the advantages contained in the same, heretofore described, and defined in the subjoined claims.
