Specification of Letters Patent. Y Patnted Nov. 30, 1915.
Application filed April 1, 1915. serial No. 18,566.
T all whom t 'may concern.'
n Be it known that I, REGINALD F. HERSEY, a citizen of the United States, residingat Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Hand-Vises, of which the following is a specification.
This invention contemplates an improved hand vise or toolespecially adapted for use in manually holding an object with one hand while the o-ther hand may be employed in operating upon the said object. v
The invention has as its primary object to provide a tool of this character adapted to be locked in engagement with the work and which may be readily operated to either engage or free the work.
A further object of the invention is to provide a tool of this character having coacting arms simultaneously adjustable to adapt the too-l for -use'in connectionwith various sizes of work, and wherein the said arms will be provided with swingingly mounted jaws adapted to thus seat iiatly upon opposite sides of the work in secure engagement therewith. l
The invention has as a still further object in this connection, kto provide means for limiting the swinging movement of the jaws in each direction; to provide yieldable means normally urging the jaws to the limit of their pivotal movement in one direction, and to provide means for simultaneously moving .the arms carrying the jaws, for
urging the jaws into engagement with the work.
The invention `has as astill furtherobject to provide yieldable means connected to said arms for normally urging the inner ends of the Varms toward each other and consequently normally holding the jaws mounted upon the outer ends of `the said arms in spaced relation to receive the work. And a still further object of the invention is to providev a tool which will be simple in construction, which may be easily manipulated, and which will be found thoroughly efficient 1n use.
Other and incidental objects will appear as the description proceeds and-in the draw-V ings wherein I have illustrated the preferred embodiment ofthe invention and wherein similar reference characters designate corresponding parts throughout the several views, Figure 1 is a side elevation of 1ny improved tool, Fig. 2y is a horizontal secj tional view of the device more particularlyV illustrating the detail construction thereof,
Fig. y3 is a transverse .sectional view Vtaken.
on the line 3-3 of Fig. Q/and looking in the direction of the arrows. Fig. 4 is a plan view more particularly showing thev construction and mounting of the jaws of the device.
Referring more particularly tothe drawings, my improved tool includes a shank which at one extremity, is longitudinally bored as shown at 11 and which is medially enlarged to provide an annular body-portion 12. VSurrounding theboredextremity 11 is a preferably woodenhandle 13 which, at one end is adapted to abut the body portion 12 and is preferably providedrwith a ferrule 111, it being' observed that the adjacent endo-fthe shank is overturned for connecting the handle therewith.
The shank 10 at its free end, is bifurcated to form spaced ears 15 having alined openings formed therein ini which vis freely mounted apin 16 having right and left hand screw threads formed onthe respective eX- tremities thereof. Keyed upon` the pin 16 and freely received betweenthe ears 15, is an annular nut 17, the periphery of which is preferably knurled as best shown in Fig. 1 of the drawings. `It will thus be observed that the pin 16 may be readily rotated through the medium of the nut 17.
Mounted upon the pin 16 are coacting arms 1,8, each of which intermediate its ends, isV enlarged to provide a body portion 19. lThe body portion 19 of each of said arms is provided with a transversely extending opening 2O which enters through opposite edges thereof and is further provided with a cylindrical opening intersecting the opening 20 and disposed at substantially right angles thereto.v the said last mentioned opening entering through opposite side faces of bifurcated to form spaced lugs or extensions V22 which extend from the body portions 19 of thel said arms in oblique relation thereto, the extensions of one arm projecting laterally towai'd the extensions of the other arm. rfhe extensions 22 ofeach arm adjacent the outer kterminals thereof are provided with alined openings receiving a pivot pin 23 upon which is pivotally mounted a jaw 24, freely received between the said extensions, the jaw of one arm being adapted to coact with the jaw of the other arm.
Each of the jaws 24 is provided with a laterally extending head -25 as best shown in Fig. '4 ofthe drawings, which is formed with a substantially fiat knurled working face adapted to engage the workin the manner shown in Fig. 1 of the drawings, the work being conventionally illustrated therein. |The 'heads 25 ofthe jaws upon the inner sides thereof, are arcuatelyv cut away to freely receive the rounded terminals of `Vthey extensions 22Y and to provide at their outer extremities, laterally projecting shoulders 26 extending upon opposite sides of the said extensions and adapted to contact with the adjacent inner edges thereof for limiting the jaws in their pivotal movement in one direction upon the pins 23. rlhe said jaws are each provided with fa tail 27 which project 'between the extensions 22 toward the body portions 19 in the manner best shown in Fig. 2 of the drawings, the said tails being integrally formed on the heads 25 and extending laterally therefrom. At their outer free ends, the tails 27 are beveled yto seat 'flatly against the flat faces or shoulders 28'formed on the said body portions 19. As will be clear, the tails 27 of the said aws are thus adapted to limit the aws in their pivotal movement in 'a2 reverse direction to that deined by the shoulders 26.
rlhe body portion 19 of each of the arms 18 is provided with `a substantially cylindrical socket 29, while vthe head 25 of each of the jaws 24 ata point substantially midway of its ends, is provided with a similar socket 30. Seating at its ends in respective corresponding sockets 29 and 30 is a substantially helical spring 3l' of 'the expansive type. The springs 31 are disposed substantially midway between the extensions 22 and normally urge the jaws 24 to the limit of their outward pivotal movement with vthe tails 27 thereof in engagement with the rformed thereon.
shoulders 28. n The purpose in the particular mounting of the jaws 24 thus described, will be presently referred to.
The inner extremities of the'arnis 18 are `curved laterally toward each other and at the .inner ends thereof, are reduced being each provided with a terminal foot 82 havingan inner arcuate face or shoulder 33 As best shown in Fig. 2 of the drawings, the body portion12- of the shank is formed with a transversely extend-- ingrecess 34 which opens through' opposite sides thereof and in rwhich the inner teri'nie nals of the arms 18 are freely received. j
It will be observed upon reference to Fig.l
10.V Freely mounted within the bore 11 of the shank is a wedge 37 in the nature of a rod which adjacent `one end thereof, is cut away upon opposite sides to proyide transversely extending notches 38.v Thlcj adjacent extremity of the rod 37 is iatteneeland is provided with avwedge shaped terminal 39 having oppositely inclined shoulders 40 adapted to be projected between the inner extremities of the arms 18 to engage the curved faces 33 of the feet 32 of the said arms. At the contiguous extremity there# of, vthe rod 37 is reduced to provide a pin 41 adapted to be freely received within the bore the said pin being-disposed to engage within the said bore for Guiding and suni00` porting the adjacent terminal of the rod 37. Formed upon one side of the body portion 12 of lthe shank are spacedlaterally projecting ears 42 between which is pivotally mounted an operating lever 43, the said lever being preferably detacliably connected with the eais by a suitable pivot pin' 44. The lever 43 is of a length substantially equal tothelength of the handle 13 and adjacent the outer extremity thereof is transversely curved to seat against the said handle. Integrally'formed on the lever at the inner extremity thereof, are spaced laterallyprojecting arms 45 arranged to freely embrace the adjacent -portion of the rod 3.7
to engage within the notches 38. The arms 45 are `each of substantially spatulate form, to thus present upon- Vopposite edges thereof, cam faces 46 adapted lto engage opposite end wallsjof each of `said notches for moving the rodf37 longitudinally within the shank 10.
Mounted upon thearms 18, adjacent to the inner extremities thereof, are oppositely disposed pi'ns 47`which are arranged in alinenient with the bore 86 formed in thei shank 125 24 will consequently be similarly adjusted to receive the workand in this connection, particularattention is directed Yto the fact that owing to the pivotal mounting of the said jaws, the jaws will, upon being brought into contact with they work, move into such angular relation to the extensionsV 22 of the arms 18 supporting the jaws, as to bear flatly against the work in themanner shown in Fig. 1 of the drawings,L even though the work be relatively thick or relatively thin.
However, it is to bek observed that the jaws are positively limited in their pivotal movement upon the extensions 22 in each direction and are normally urged in one of said directions away from each other by the springs 31, to receive the work.
In use, the lever 32 is swung upon its pivot 44 laterally away from the handle 13. Such movement of the lever will cause the arms 45 to engagewithin the notches 38 of the rod 37 and consequently move the rod longitudinally within the bore 11 of the handle toward the outer end thereof. The wedge shaped terminal 39 will, as a consequence, be moved out of engagement with the feet 32 of the armsv 18 when the spring 48 will move the inner ends of said arms toward each other causing the arms to pivot upon the pins 21 and consequently move the jaws 24away from each other. The work is then insertedbetween the jaws and the lever 48 is moved toward the handle to the position shown in Fig. 2 of the drawings. It will be noted that when the handle is so moved, the cam faces 46'of the arms `45 of the handle notches 38 to move the wedge shaped terminal 39 of the rod 37 longitudinally between the feet 32 of the arms 18. The inclined walls 40 of the said wedge shaped terminals will thus engage the arcuate faces 83 of the said feet to force the inner terminals of the arms 18 away from each other and consequently move the jaws 25 into binding engagement with the work. It is further desired to direct particular attention to the fact that the cam faces 46 of the arms 45 are so disposed relative to the pivot pin 44 of the operating lever 43, that when the said lever is thus moved to cause the jaws 24 to engage the work, the lever 43 is adapted to assume a position upon one side of a pivotal center, with the wedge shaped terminal 394 consequently locked between the inner ends of the arms 18. V
VItwill thus be seen that I provide a very simple and eiiicient tool for the purpose set forthwhich maybe readily operated by one hand to hold the work, while the work may be manipulated with the other hand. It will further be seen that since, after theV aws 24 are engaged with the work, the operating `lever 43 will be urged to the vnormal position particularly shown in Fig. 2 of the drawings, that the tool will not be liable to become disengaged from the work and thus will provide avery `eiiicient tool in practical use.
