No. 846,991 3 Claims. (Cl. 269-49) The present invention relates to new and useful improvements in structural refinements in a vise or work holder definable as a static or tension free type of vise.

It is directed particularly to the provision of combination sine plate and vise of improved design and having general utility in the arts, it having certain special advantages in that connection. It will be understood however that it may be applied to work holders generally as used on machine tools and the like.

The invention resides in the particular arrangement, construction and relationship of the various elements, components, and instrumentalities of sine plates and precision Vises as exemplified in the detailed disclosure hereinafter set forth wherein the objects of the invention, as defined in the paragraphs below, will be apparent.

It is a principal object of the present invention to provide an inventively novel and improved construction of the type in which a vise clamp is free of tension and is held relative to a base by means of a pair of rigidly fixed upstanding members identified in one instance as a stationary or fixed jaw and in the other instance as a screw retaining post. The slidable jaw of the device is movable relative to the base by the coaction of an operating member which is transversely receivable through a screw retaining post. A static vise clamp embodies a pair of interconnected static vise jaw portions which absorb all of the holding pressure, one of the jaw portions bearing against and outside of the so-called stationary or fixed jaw and the other of the jaw portions bearing against and outside of the so-called screw retaining post. The holding pressure of the stationary or fixed jaw and the slidable jaw on the work disposed therebetween is furnished by the jaw portions of the static vise clamp which yield toward each other or away from each other as pressure is applied thereto or taken away therefrom through a stationary locking screw revolving nut and retaining collar by means of a ratchet crank or wrench.

The vise and jaw hereof are stationary and are fixed to the base under conditions of high accuracy. They remain so fixed when any holding pressure is applied. The greater the pressure, the greater their fixed position. Accordingly repositioning of work accurately is possible for any desired position, the static point of the clamp remaining in the precise same position regardless of the pressure applied by the vise clamp member. As pressure is applied through said vise clamp member, same is free to flex or bend as pressure is applied by its operating screw so as to offer a truly static vise in action.

The vise base is so constructed as not to bend or flex either along its lower base portion or at its upwardly extending extremities at opposite ends of the lower base portion as the result of any work holding pressures applied.

With prior art devices, regardless of how strongly they are built, some bend through the application of their own pressure by their own bodies so as to fail as accurate holding devices. Worse, as more pressure is applied, this objectionable bending increases.

Another object hereof is to provide a simple device incorporating a fixed jaw and a rectilinearly movable and adjustable jaw whereby the work piece may be clamped against the opposed faces of said jaws and can be positioned in an accurate manner in various positions in a plane parallel to the planes of the said clamping faces.

er 3,621,132 Patented Feb. 13, 1962 The said fixed jaw and the base of which it is a part and from which it upwardly projects serve as static points, said points remaining in the precise same posit-ions throughout all work holding pressures exerted thereagainst by the vise clamp.

By means of the device hereof, improved means for holding work at a selected angle, while machining operations are performed thereon, is provided, same incorporating a sine vise having unique work holding elements and adjusting means for the movable element thereof whereby, when the device is disposed as a sine bar and/or as a normal or conventional vise, it is adapted to hold work in an accurate manner at any desired angle relatively to the longitudinal axis of the vise in order to facilitate operations of tools of the operating machine upon the clamped work piece.

A further object hereof is to provide means for obtaining a substantial range of movement for the movable elements thereof and cooperating guide means for guiding said elements in their movements into and out of operating positions.

Other of the chief objects and purposes hereof are to provide advantageous structural and operational features in a device of the class to which reference has been made so as to provide an apparatus having the following meritorious characteristics: first, a simplicity in construction and therefore an adaptability to economical manufacture without sacrifice of its essential characteristics as a precision instrument; second, a uniqueness in engineering design of coacting parts wherefor the components are coordinated for facile assembly and when once assembled are positively and securely retained in operative relationship; third, an ease of installation; fourth, a high degree of efiiciency and accuracy and dependability in its operational use; fifth, the attainment of a flexibility or a capability of adjustment by which a large variety of work can be produced by means of the same device; sixth, the achievement of a greater ease in repairs and consequent reduction in maintenance costs than has been possible in related devices heretofore known; seventh, the provision of a construction which may be readily installed with respect to the various purposes for which it is intended, and eighth, the provision of such other improvements in and relating to combination sine plates and work holding devices of the type above referred to as are hereinafter described and claimed.

Further objects hereof are to provide a static or tension free vise in combination with a sine plate conformable to the desiderata of the preceding paragraph and offering specific improvements in the various operating instrumentalities comprising same, which themselves are minimum in number, so that it is simple and compact in accordance with the demands and desires of manufacturers and purchasers alike and so as to provide distinct advantages of distinctiveness in appearance, practicableness in value, durableness in organization and reliableness in operation.

In addition to the practical advantages which I have ascribed to my novel apparatus, it will be observable that a chief feature of the invention resides in the fact that it is well adapted to withstand the usage to which sine vises are ordinarily subjected, convenience of arrangement of parts and extreme compactness, both conducive toward the provision of-a device of small proportions and having ruggedness and durability, being further desirable features that have been borne in mind in the development of the present invention.

With these and other objects and advantages in view, some of which will be in part obvious and apparent and some of which will be in part more fully pointed out and I to the end of attaining these and any other object and advantage hereina ter reasonably appearing, it will be explained that the invention consists substantially in the combination construction, location and relative arrangement of parts, as described in detail hereinafter, as shown in the annexed drawings, and as defined with particularity in the appended claims forming a part hereof. It should be understood however that this physical embodiment is only indicative of but one of the various ways, albeit the preferred exemplification, in which the principles of the invention may be employed and in which the component parts may be combined and arranged. The invention is not restricted to said embodiment and same is not intended to be exhaustive of, nor limiting of, the spirit hereof. That is, the precise construction of the figures of the drawings need not be slavishly followed as, of course, the device may have to be adapted or modified in accordance with the use to which it is to] be put. All of this will be obvious to those skilled in the art to which the invention pertains, who willunderstand that 88.1116 may be incorporated in any of several different constructions.

The protection which is sought for this invention is covered by the language of the specification and the spirit represented thereby.

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined, but useful embodiments may be produced involving less than the whole.

The description which follows is of an exemplary form of the invention and is given with a view to illustrating and explaining the precise nature of the principles of the invention and their embodiment for practical use, in order that others may be enabled to adapt and modify them in numerous embodiments, variations and modifications, each as may be best adapted to the conditions of any particular use. It is premised, however, that such adaptions and/or modification should be and are intended to be comprehended within the meaning "and range of equivalence of the below subjoined claims, there being no intent to have this invention limited to or circumscribed by any specific details of materials, dimensions or the like.

The novel features which I consider to be characteristic of my invention, as to its construction and organization and as to its methods of manufacture and operation, will be best understood from a consideration of the following detailed description forming a part of this specification.

In the drawings, like characteristics of reference or numerals are employed to designate like or corresponding parts throughout the several views.

FIG. 12 is a sectional view on the line 12-42 of FIG. 11.

I have shown my improvements as applied to a sine vise having a fixed jaw and a rectilinearly movable adjustable or slid'able jaw.

The sine vise is of a structure such that the visebase can readily be held in various positions wherein its longitudinal axis is tilted relatively to a horizontal plane. This enables the work piece to be correspondingly tilted for facilitating operations to be performed thereon in the way of cutting, grinding and the like.

Before the structure so illustrated is specifically described, it is to be again emphasized that this invention is not limited to the structural details or arrangement of parts here shown since a sine vise construction embodying the present invention may take various forms, it being susceptible of various modifications and alternative constructions. I do not thereby intend to limit the invention to the specific form disclosed, but rather intend to embrace herein all modifications, variations, alternative constructions, and equivalents falling within the spirit and scope of the invention.

With continued reference now to the drawings, I have shown a vise construction in which my invention may be advantageously incorporated as illustrated in FIGS. 1 and 2. v

The vise construction embodies a base or bed plate 2 generally corresponding to a sine bar and hereinafter called a sine base plate. Same has one or more suitable lugs 4 on opposite ends thereof for purposes of rigidly securing the device to any suitable bed or table of a machine tool or other support 'wheiefor a piece of work clamped in the vise may be operated upon by a tool. The machine tool may comprise a milling machine, shaper, planer, drill, press, or whatever else may be suitable and desired. By way of example, the member 2 may be supported on and connected to a magnetic chuck face.

As shown, the plate 2 is also provided with a smooth finished uppermost or top planar face forming a bottom support for other components, hereinafter to be described.

For convenience, the left hand end of the vise, as viewed, will be called the rear end and the right hand end will be called the front end.

Brackets or sine roll blocks 6 are secured to opposite side edges at the rear end of the sine base plate 2 as by suitably spaced screws or dowels ti or the like.

A vise base It as best shown in FIG. 6, is provided with pivot members 12 which are secured to opposite sides at the rear end thereof as by screws 14- or the like. Each pivot member 12 is journalled in the adjacent sine roll block 6 wherefor the vise base It may be swung on its turning axis thus formed relative to the member 2.

The upper planar face of the vise base ltl is adapted to form a bottom support for the work piece held by the vise and for other components of the device as will be observed.

A sta-tionary or fixed jaw is is mounted on and secured to the upper side or face of the vise base It'll, at the rear end thereof as by screws or dowels 18.

A screw retaining post it? is mounted on and secured to the upper side or face of the vise base It at the front end thereof, as by screws or dowels 22.

A static vise jaw or vise clamp member, generally indicated by 24, is illustrated in FIGS. 8 and 9, and is in the form of a 0 having a longitudinal, substantially horizontally disposed portion 26 intermediate opposite upstanding jaw portions 28 and 30 integral therewith.

The static vise jaw or vise clamp member 24 will be understood with reference to the vise base it and its component parts.

The vise base it is provided with a centrally-disposed longitudinally extending slot 32 along its bottom planar or under surface for the receipt therein of the complemental portion 26 of the static vise jaw 24, and the stationary jaw 16 and the screw retaining post 20, at opposite ends of the vise base 10, are provided with vertically extending slots 34 and 36 respectively, which slots are adapted to receive the respective upstanding jaw portions 28 and 30 of the static vise jaw 24.

The vise base 10 is also provided, along its upper planar face, with-a pair of transversely-spaced, longitudinallyextending, beveled or dovetail guideways 3th A movable or slide jaw, generally indicated by 40 in FIG. 10, is rectilinearly movable relative to the vise base 10, and has guides or gib blocks 42 depending therefrom and secured thereto as by screws or dowels 44. The guides or gib blocks 42 are transversely spaced so as to be slidable in the beveled or dovetail guideways 38 in the upper planar face of the vise base for aiding in etfectuating the rectilinear movement of the slide jaw longitudinally of and relative to the vise base 10 into and out of work-clamping positions in coaction with the stationary or fixed jaw 16 mounted on and secured to the vise base 10.

The guides can be adjusted as desired relative to the clovetail guideways by suitable adjustment of the screws 44 in such manner as to efiect any desired vertical or lateral adjustment.

It will be apparent that the stationary jaw 16 and movable jaw 40 provide rigid and satisfactory work abutment members adapted to engage and/or center work therebetween.

The innermost and opposed vertical Work-engaging faces of said jaws may be provided with centralIy lOcated vertically-disposed notches (not shown) having equal diverging sides at right angles to each other in such manner as to offer etfective work locating means for round or other odd-shaped pieces of work.

A revolvable, elongated, internally-threaded, ratchet, tube-like locking nut member 50 is receivable in appropriately dimensioned and suitably aligned openings in the adjacent jaw portion 30 of the static vise jaw 24, the screw retaining post 20, and the movable jaw 40.

Said nut 50 is provided with a retaining collar 52 secured thereto. The collar 52 is rotatable in the screw retaining post 20. Suitable lubricating means may be provided therefor.

A coaxial stationary locking screw 54 is shrouded within the locking nut member 50 and has a forwardly-disposed extremity in threaded engagement with the internal thread of member 50 and a rearwardly-disposed extremity anchored against rotation as by pinning 51 in the movable or slide jaw 40.

The nut member 50 is turnable in one direction or the other so as to move the screw member 54 and, in turn, the slide jaw 44). Stated otherwise, the slide jaw 40 is observable as being adjustable longitudinally of the vise base 10 by the operating member 50, samebeing journalled in the members 30, and 49 for adjusting the said slide jaw through the aforedescribed connections with the screw 54.

The adjustment is efiected by turning a suitable operating head or turning member whichmay be in the form of a ratchet Wrench, as generally indicated by 56 in FIG. 5. Same forms no ,part of the present invention and accordingly will not be described in detail.

At the rearwardend of thevise base 10, and at one side thereof, as in FIG. 6, a slot 60 and a recess 62 communicating therewith are provided. Both are disposed in the generally vertical plane inset inwardly of the planar face of the said side of the vise base 10. A degree segment 64 is pivoted at 66 to the sine base plate 2 and is provided with a bevelled side edge 68. The slot 69 is bevelled to complement the bevel of the degree segment 64.

The degree segment 64, as shown in FIGS. 2 and 11, is provided with a scale 65' comprising indicia of various angles in order that the member 11 may be swung with respect to its turning axis and positioned at a desired angle relative to the member 2. The scale 65 is registrable with a line (not shown) applied in a suitable manner on the member 10 to indicate each angular position.

A lock member 70 lies against the bevelled side edge 68 of the degree segment 64, and a screw 72 is provided for any desired tightening of the member 70 at any desired angular position.

Adjacent the forward end of the vise base 10 and at the underpart thereof, a transversely-extending cut-away portion or groove or notch with a suitably inclined wall is provided as indicated in FIG. 6, to receive in seated or nested position therewithin and to suitably expose a sine roll 76 extending transversely of the vise base It Said sine roll is suitably attached to the vise base 10 Within this cutaway portion by angularly-directed longitudinallyspaced screws 78 extendable through the roll and into the member 10.

When and as desired, the vise base 10 may be angularly supported, upon its pivotal connections with the plate 2, at its rearward end, and upon one or more spacer or measuring blocks 80, such as shown in FIG. 12, supported upwardly of the upper face of the plate 2, at its forward end and disposed under the roll 76 in known manner said blocks 80 being of such height as to position the member 10 at the desired angle. That is, the measuring blocks enable the vise base 10 to be held in tilted posi-. tion. When the .vise is tilted lengthwise in the manner above mentioned, that is, by moving the longitudinal axis of the vise base 10 to the desired angle relatively to the horizontal plane, the appropriate measuring or spacer block or combinations thereof may be disposed in supporting relation under the roll 76, portions of said block or blocks being extendable into the aforedescribed cutaway portion or groove or notch if necessity dictates.

With reference to FIG. 11, the vise base 10 is shown as being shifted to one of its permissible angular locations relative to the sine base plate 2 by the use of a combination of two difierent size measuring blocks 80 upon which the sine roll 76 may rest, all so as to enable the various'components to be disposed in an accurate manner.

Locking means is provided for the vise base in any desired inclined position and includes a lock bar or position locking strap 82 pivoted at 84 to the sine base plate 2. Said lock bar is provided with a curved slot 86. A lock screw 88, in threaded engagement with the v-ise base 10, extends through the slot 86 and may be tightened against the lock bar 82 to hold said vise base 10 against movement relative to the sine bar plate 2. Of course, there may be locking means similar to that described on each of the opposite sides of the apparatus.

The vertical portion 28 of member 24 is provided with a stud 90 which is receivable in an operative inset 92 of the part 16 of the vise base 10, as shown in FIGS. 6 and 8.

I As shown in FIG. 4, a size block such as 98 can be used with a three roll sine bar 100 of the cross or compound type having rolls 102 secured thereto as by screws 104 or the like in the well known manner. By such means, the work piece can'be held at compound angles, it being obviously possible to adjust it to a plane perpendicular to the longitudinal axis of the device as well as in a vertical plane longitudinal to the axis, all tending to enlarge the versatility of the device and the work performable therewith. That is to say, it is herewith possible to locate the work piece relatively to any desired plane or universally by the proper adjustment of the respective instrumentalities relatively to the member 2.

As a result, machining or other operations are facilitated and it is possible materially to increase production therewith, the versatility thereof being greatly enlarged.

In the use of my improved construction, it will be evident that when the work is placed against the stationary jaw, the slidable jaw may be readily and quickly moved into clamping relation by suitable rotation of the turning member in such manner as thereby to enable the work to be disposed in the proper manner relative to the operating tool.

Further, it will be apparent that the work, when completed, may be similarly released by a reverse operation of the turning member and new work thereafter inserted with a minimum of loss of time due to the facility with which these operations may be performed and the rapid 7 movement of the slidable jaw made possible through the easy operation of the turning member.

It will be seen from the above that the invention provides a simple and efitective work holder in which the work can be readily given an accurate compound adjustment. The work piece can be readily and accurately adjusted in a multiplicity of planes which are angular relative to each other.

Although my invention has been specifically described and illustrated herein with particular reference to a combination sine plate and work holding device it should be appreciated that its utility and application extend beyond the particular type of structure illustrated and its broad scope and concept comprehend the useful and novel features set forth when combined with any work holding device of the general type contemplated and thus, with respect to the scope of the invention, the foreging material is to be considered as illustrative only.-

It is to be further understood that the specific phraseology or terminology herein employed is for the purpose of description and not of iimitation. Although the terms and expressions hereof are employed for purposes of identifying various components, they are used in a generic and descriptive sense only and not for purposes of limitation and are intended to be as generic in their application as the art will permit.

Without further analysis, the foregoing is intended to so fully reveal the gist of my invention and its construc tion and operation that others can, by applying current knowledge, readily adapt it for various applications without omitting features which, from the standpoint of prior art, fairly constitute essential characteristics of its generic and/or specific aspects. Stated otherwise, it is not desired to limit this invention tothc exact construction shown and described as the objects hereof may be attained by the use of constructions different in certain respects from that disclosed.

The invention is claimed, broadly as well as specifically, as indicated in the appended claims, and same are desired to include within the scope thereof all of said suitable variations, modifications and equivalents by which substantially the results of the invention may be obtained through the use of substantially the same or equivalent devices or means. Accordingly, limitation hereof should be made only as determined by a proper interpretation of the subjoined claims.
