'The present vinvention relates to aviseconstruction and more particularlyto the construction of a hydraulic visev having meansI to ypractically eliminate all frictionrbetween th'evxed and movable jaw members.
While the present invention will herein be illustrated and described as a hydraulic vise,l it is to be understood that the' improvements may be incorporated in vises, or similar machines, other than hydraulic vises. l
In the operation 'of some vvises, and particu` larly hydraulic vises, a conslderableamount of force is necessary to hold-the'movable jaw member against the workpiece vwhich is'against' the fixed jaw. Where such a vise isihydraulically operated, aheavy loadis imposed upontheY movable jaw member, and sometimes quite-an effort is needed to separate the movable jawmember from the work piece when thevjobis linished.
f It is, therefore, an'v important object ofafthe 'present invention to yprovide .av vise. construction f in which the movable jaw member is mounted on rthe fixed jaw member, with vantifriction means,
to enable easy operation of themovablejaw member towards and away from the xed jaw.
Anotherfobject of the present invention is to provide a hydraulic vise having a ball bearing support for the movable jaw member.
yAnother object of thevpresentinvention is to provide a hydraulic vise having ya minimum of friction between vthe movablevjpawimember and the fixed jaw member. f A still further object of the present `invention is to provide a hydraulic-vise havingcooperatingways for ball bearings and gibsgfor re- 2 Claims. (o1. S14-47.2); i
Figure 3 is a view, partially in end elevation and partially in section, taken in the plane of unevIIL-'III of Figure 1.
Figure 4' is a top plan view of the vise of Fig- Aure 1. l f
The drawing will now be explained.
Referring to' Figure 1, a vise is illustrated including 'a xedjaw memberA and a movable jaw member B. The fixed jaw member A has an elongated body having feet 5 and 6 for resting ony a" surface, such as a bench, and an upwardly and inwardly turned end 1 providing a fixed jaw 8. The face ofthe jaw 8 has a hardened plate insert 9, retained by suitable screws.
The foot 5 has an end extension II slotted at iZwto receivev a lag screw or bolt for securing this -end'of the vise to a support. The feet 6, which taining the balls within the length ofthe mov- 'f able jaw member.
Another and yet further object of the `present invention is to providey avise construction -.in whichthe movable jawmember is supported on the fixed jaw memberby ballwbearings, which` bearings support the entire weight of the,mo v able jaw member.
The invention has for a further object the provision of a. practically frictionless vise construction.
The above, other and further objects of the present invention will be apparent from the following description and accompanying drawings.
An embodiment of the present invention is illustrated in the accompanying drawing and the views thereof are as follows:
Figure l is a side elevational view of a hydraulic jack embodying the present invention.
Figure 2 is a vertical sectional View taken in the plane of line II-II of Figure 1.
extend laterally ofthe xed member A. as shown fin Figure 4', are provided with similar slots I3 for a similar purpose. l
Set into the upper portion of the fixed mem berA is 'a plate I4 horizontally disposed and fastened in place by suitable bolts I5. The plate I-4 is horizontally disposed with a horizontal -upper surface Ilj.v Side margins I' and I 8,of the plate vI4 are vertical and eachhas formed in it a lengthwise extending semi-cylindricall groove I9 and 210;" respectively. The grooves being formed with their'diameters in the vertical faces .or margins of theside surfaces of the plate I4.
The jmovable jaw member B has an end portion 2| constituting a movable jaw, which portion vis provided'with ahardened plate 22held in place by suitable screws.l I y As `maybejobserved in Figure y2, the movable jawmember B straddlesthe plate I 4 of the fixed jaw member.
Attached' to opposite sides of the movable yjaw .member-B are plates 23 and 24 held in place by suitablescrews or bolts 25. i laptheside .margins of the platey I4 of the ,fixedmember A.. `The inner faces of the plates 23 The plates 23 and and 24 are formed with lengthwise extending grooves 26 and 21, respectively, the grooves 26 and 21 in the side plates complementing the grooves I1 and I8 in the side margins in the plate I4 to provide ball bearing ways, or race-ways, for receiving ball bearings 28. It will be observed, in Figure 2, that the entire weight of the movable jaw member B is carried by the ball bearings 28 to reduce friction to a minimum.
The balls 28 are retained in the ways within the length of the movable jaw member B by means of gibs 29 and 30 applied to the ends of the side plates 23 and 24 of the movable jaw member, which plates are recessed at 3 I to stradmember, adjacent the jaw 2| of the same, to nors mally withdraw the movable j aw member B from the jaw 8 of the xed memberfA.
A ram 36 entered in the movable jaw member B is positioned therein to moveethejawmemher to the right, as viewed in Figuresl andli', whenk ever hydraulic pressure is applied to it.
Hydraulic pressure is applied. to .the ram 3.6 by` connection of a suitable source of 'pressure to the adapter or coupling, indicated generallyratiaii It is to be understood that the movable jaW member. is` movedtoward the xedljaw.- member by. hydraulic pressure applied tor the rams 3.6, which pressure is regulated by f a suitable? valve, usually actuated by a treadleengageable-by a foot of the vise operator. The movable jaw member is moved against a work piece-to clamp it'between` the fixed jaw and.- rnovable jawby'hy draulic pressure, and heldas long'asis necessary for the operator todo anythingfontheworkpiece.
When work-has been nis-l'iedy .pressureagainstl the ram 3Bis. relieved, whereupon theA spring.` 3.3 functionsfto withdraw the movable jawy from the `xed jaw and'release the Work: piece-theretofore held between the same'.
It; willbe evident' that .the ball; bearing mounting of` the-movable member B on the-Xed mem- .berf A, in the-.manner illustrated and. described, reducesv friction to a minimum*- and. all of* the weight of the movable jaw member: is carried on and supported by the balls 28 ofgathetball-bearings.
The ball bearing grooves 11,. I8?, 2,6f 'and'.Zl, heretofore described, were described as each-being` semi-cylindrical.. In actual. practice' these grooves, when brought together to formball receiving Ways, are'slightly less than trulyy semicylindrical, to enable the confronting faces; of
the platesy 23 and 2,4 in the side margins' ofv the plate," I4 to be separated a slight distance; to prevent any bindingV between..- the:` movable jaw member-and the fixed jawV member.
It will be observedy that the vise construction herein disclosed is one which Willienablethemanufacture of a practically frictionlessvise, at minimum cost, as the parts are simple, and of such nature as to bereadily formed'andmachined, as Well as assembled, in an expeditious manner.
A second spring 33a is shown as parallel to spring 33. The spring 33a is hooked at; oneend to a projection 34a on the left-hand ofmember A. The other end of the spring is'hookedover a projection 35a in the movable jaw member; adjacent the jaw 2l of the same, to cooperate-with 4 spring 33 to withdraw the movable jaw member B from the xed jaw 8.
A screw 38 is threaded into the end piece 39 of member A to serve as a. stop for retrograde movement of the movable jaw member B under iniluence of springs 33 and 33m Thexinvention has herein been described more or less precisely as to details, yet it is to be understood that the invention is not to be limited thereby. .as changes may be made in the arrangement;v and proportion of parts, and equivalents may be substituted, without departing from the function'l and scope of the invention.
