Patented Feb. 4 1, 1947 M fw' UNITED STATESPATENT UFFICE CAM OPERATED VISE Maher Moore, Los Angeles, Calif. Application September 2, 1944, Serial No. 552,495
lViy invention relates to a new and improved vise for gripping and firmly holding work of various kinds, and the principal object of my invention is to provide a simple, compact and convenient vise of the quick acting type which does not involve the threaded rod or shaft common to the conventional forms of vises now in general use.
A further object oi my invention is to provide a vise o-f the character referred to, having simple and emcient means for rmly clamping and securing work and which requires turning of the operating handle or knob only through an arc of approximately 90 degrees.
A further object of my invention is to generally improve upon and simplify the construction of the existing forms of quick acting bench vises now in general use.
With the foregoing and other objects in View, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which:
Fig. 1 is a side elevational view of the improved vise with parts broken away and in section.
Fig. 2 is a horizontal section taken on the line .5f- 2 of Fig. 1.
Fig. 3 is an enlarged cross section taken on the line 3--3 of Fig. 1.
Fig. i is an enlarged cross section taken on the line li-ll of Fig. 1. i
5 is a section taken on the line 5-5 of Fig. 3.
Fig. 6 is an enlarged detail view showing the gripping plates in engagement with the sliding and rotating rod.
Referring by numerals to the accompanying drawing which illustrates a preferred embodiment of my invention, I@ designates the Xed jaw of the vise which may be fixed or swivelled to a bench E or like support and II designates the movable jaw. which is formed integral with or iiXed to a horizontal bar I2 that is arranged for sliding movement through the lower portion of said fixed jaw.
A. horizontal rod I3, disposed above and parallel with bar i2, is arranged for sliding and partial rotary movement in the two jaws and the greater portion of said rod has portions on opposite sides cut away so as to form ilat faces I4.
Mounted for rotation on rod I3, in a bearing i5 in jaw ii, is a ring i6 having on its outer end a pair of inclined cam faces I I separated by f 4 Claims. (Cl. 81-26) shoulders such as I3 and formed in the inner end of said ring is short longitudinally disposed slot t9 which receives a pin 2l] seated in rod I3.
Interposed between a flange 2l on rod I3 and the inner end of ring It is an expansive coil spring 22. The inner end of sleeve It bears against a shoulder Ilia on the movable jaw.
Loosely mounted on the outer end portion of rod I3, is a short sleeve 23 provided on. its outer end with a hand wheel 2e and said sleeve being retained on said rod by av disc 25 and screw 26.
The inner end of sleeve 23 is provided with inclined cam faces 2l, which oppose cam faces il, with shoulders 28 opposing shoulders I8.
That portion 0f jaw Ill through which rod lil passes, is provided with two openings 2!! and Sil separated by a wall 3|; and mounted to rotate with and slide upon said rod, within opening Sil, is a sleeve 32 provided on one end with. a flange 33 and projecting from said flange 90 degrees apart,lare shoulders 3i. (Seelig. 3.)
A stop lug 35 is formed on wall 3l in vertical alignment with the axis of rod I3, between the shoulders 3G, thus limiting the rotary motion o said sleeve in either direction.
A torsional spring 3G surrounding sleeve 32, with one end connected thereto and the other end bearing on the bottom of opening Se, biases rotary movement of said sleeve in one direction.
Loosely mounted on rod I3 within opening 2S is a series of hard metal plates 3l, the lower edges of which rest on the bottom of said opening between. lugs 38 and said plates normally occupy slightly inclined positions as illustrated in Fig. 5.
These discs are `provided with openings 39 for the accommodation of rod t3 and the horizontal diameters of these openings are slightly greater than their vertical diameters and thus when rod I3 is rotated 90 degrees so as to position the ilat faces lll at top and bottom, the curved faces oi said rod between said at faces, will be out of contact with the horizontal ends of the openings 39 as shown by dotted lines, Fig. 4.
Plates 3l are normally retained in their inclined positions by a disc i9 loosely mounted on a pin M, in the upper portion of opening 29 and forced against said plates by an expansive coil spring Ma.
Under normal conditions, rod I3 and jaw Il carried thereby, are held against movement away from xed jaw til, by the biting engagement of the edges of plate 3T at the lower ends of openings 35, with the underside of said rod, (see Fig. 6).
To open the vise for the reception of work and then close said vise and clamp the work, hand wheel Z4 is rotated anti-clockwise 90 degrees, thereby correspondingly rotating rod I3 so as to position the rounded faces thereof in the ends of the substantially oval openings 31y thus enabling the movable jaw to be drawn away from the xed jaw, to permit the work to be placed between the jaws.
When hand wheel 24 is released, torsional spring 36 will act to rotate rod I3 to its normal position, such rotary movement being controlled by shoulders 34 and stop lug 35.
Inward pressure on hand wheel 2-4 moves jaw II against the work and during such movement rod I3 moves outwardly past the biting edges of plates 31.
To apply nal pressure to the movable jaw.' and securely clamp the work, hand wheel 24 is rotated clockwise and as a result of the engagement of the cam faces I1 and 21, sleeve I6 will be moved inward and correspondingly move jaw II, during which movement pin 20 traverses slot I 9.
When the Work is gripped as just described, jaw II will maintain its set position, for the inclination of faces I1 and 21 is insufficient to enable sleeve 23 and hand wheel 21, to automatically rotate backward after having been rotated clockwise, to exert the final gripping pressure on the work.
In" practice, it is only necessary to move jaw I I a'fraction of an inch when grippingthe work as just described, and for this reason the inclination of the faces I1 and 21 may be very slight, so that considerable force and pressure may be developed when the hand wheel is rotated. By turning hand wheel anti-clockwise, the cam action pressure between sleeve 23 and ring I6 is released and as rod I3 is rotated a quarter turn, jaw II may be drawn away from vthe work.
The means for locking the rod I3'against sliding movement, viz. the spring pressed inclined plates 31, may be used to advantage in various structures, for instance in quick acting wrenches and for locking any sliding members against movement in one direction.
Thus it will be seen that I have provided a quick acting vise which is simple in structure, inexpensive of manufacture, and very effective in performing its intended functions.
It will be understood that minor changes in the size, form and construction of the various parts of my improved vise may be made and substituted for those herein'shown and described, without departing from the spirit of the invention, the scope of which is set forth in the appended claims,
I claim as my invention:
1. In a quick acting visehaving fixed and movable jaws, a rod mounted for rotating and sliding movement in and through both jaws, means on the xed jaw for holding the rod against sliding movement in one direction a member mounted to slide upon and rotate with said rod, shoulders on said member, a fixed stop between said shoulders, a torsional spring between said member and said fixed jaw, a hand wheel mounted on said rod for rotating same and cooperating means between said hand wheel, rod and sliding jaw for exerting clamping pressure on said sliding jaw.
2. A quick acting vise as set forth in claim l and means whereby said rod holding means is rendered ineifective when said rod is partially rotated from its normal position.
3. A quick acting vise, as set forth in claim 1 including means for yieldingly resisting sliding movement of said rod in one direction through said jaws.
4. In a quick acting vise having xed and movable jaws, a rod mounted for rotary and sliding. movement in and through said jaws, manually operable means for actuating said rod, a perforated plate mounted on said rod within said fixed jaw for engaging and holding said rod against movement in one direction, the shape of the opening in said plate and the cross sectional shape of said rod being such as to permit sliding movement of the rod through said plate and fixed jaw in both directions,V when said rod has -been partially rotated means on the fixed jaw for receiving and holding said plate against sliding movement on said rod, a spring pressed member bearing on the upper end of said plate for tilting same, a sleeve mounted to slide upon and rotate with said rod, shoulders on said sleeve, a .fixed stop between said shoulders, a torsional spring between said sleeve and said fixed jaw.
MAI-IER MOORE.
