LUDWIG POSCH, OF JERSEY CITY, NEW JERSEY, ASSIGNOR- OF ONE-HALF 'TO MAXIMILIAN LANCER, OF NEW YORK, N. Y.
To all wlzom it may concern:
Be it known that I, LUDWIG Poser-I, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a newand Improved Vise, of which the following is a full, clear, and exact description.
This invention relates to gripping devices and particularly to an improved conof all kinds to grip articles of any shape and firmly hold the articles in position.
The object in view is to provide a gripand other mechanism which will grip articles of different sizes and shapes and will at the same time accommodate itself to the particular shape of the article being gripped.
Another object of the invention is to" provide a gripping jaw formed with a number of nested parts which will automatically assume a straight line or an irregular line as pressure is brought to bear thereon so as to accommodate different shaped articles.
A still further object, more specifically, is to provide a vise with a pair'of rounded sockets in the opposing jaws and gripping means fitted into said sockets arranged in groups with automatically adjusting grip-' ping parts.
In the accompanying drawings- I .Figure 1 is a top plan view of the device disclosing a gripping aw structure embody-' ing the invention.
Figure 2 is a side view of the structure shown in Figure 1.
Figure 3 is a top plan view of the jaw shown in Figure 1, the same being shown re-' moved and in gripping action for gripping a diamond-shaped article.
Figure 4; is a sectional view through Figure 1 approximately on line Ir-4:.
Figure 5 is a detail perspectiveview of one of the gripping parts shown in Figure 3. Figure 6 is a front view of an arc-shaped member adapted'to carry two of the gripping parts shown in Figure-5, said member embodying certain features of'the invent-ion.
Referring to the accompanying drawings by numeral, 1 indicatesthe base of a vise which in general design may be of any kind and which is provided with jaws 2 and 3. These jaws may be arranged so that one will be stationary and the other movable or both movable. The detail construction of thebase 1 and the jaws 2 form no part of the present Specification of Letters Patent.

turn are provided with a pair of sockets 14:
and 15 for receiving crescent-shaped members 16 and .17.. Each of the members 16 and 17 is provided with two arc-shaped notches 18 and 19 for, receiving the substantiallycrescent-shaped clamping members 20 and Y21. The contactor gripping face of members 20 and 21 may be as shown in the drawing or ma have some other configuration without departing from the spirit of the invention. However, these members are posi-.
'tioned to rotate on a central axis while fitting in the notches 18 and 19. The. same is true of members 15 and 16 as well as members 12 and 13 of the crescent shaped member 7. All of these members are adapted to automatically move or adjust themselves to present a straight,.curved or irregular clamping surface to an article according to the shape of the article as shown in Figure3. For instance, when the parts are in the position shown in Figure 1 and it is desired to insert a diamond-shaped article, as shown in Figure 3, the jaws are opened wide enough to receive the article and-then the article placed inposition and held until the jaws are closed. During the closing action the various crescent-shaped members will automatically move to the position shown in Figure 3 and will consequently, grip evenly the article. In this way, the article may be firmly gripped in place with the desired pressure without crushing any part thereof.
In forming the various crescent-shaped members they are preferably provided with overhanging shoulders 22 and 23 at each end as shown in Figures 4 and 5. These overhanging shoulders are adapted -to fit over a tongue structure 24 on the next adjacent crescent-shaped member.
This con-' struction holds the various members together in their proper central position while allowing a free rotary movement thereof for permitting automatic adjustment and, consemay be readily clamped With an even pressure over the clamped surface.
' The invention has been illustrated as being applied to an ordinary vise but it is evident that it may be used on a. pipe vise or any other form of vise and if desired chucks for lat-hes as Well as other machinery of said javvs, each gripping structure consisting of a pluralit of elongated nested members, said mem ers each being arc-.
shaped in cross section and having at their upper and lower ends shaped shoulders overhangin the convex face of the member and having their opp'osmg faces undercut, all of the members except the outermost ones having arc-shaped grooves in their ends forming intermediate dove-tail tongues having concave faces, fitcorrespondingly v and in all these uses, automatically adjusts ting upon the adjacent members between the itself to take care of any irregularity in the article clamped.
Vhat I claim is A vise of the character described, comprising a body, a pair of jaws mounted on the body, and a gripping structure for each shoulders thereof and engaged by the said shoulders, whereby the said members are free to rotate on their own axes, but are securely held against accidentaldispla'cement.
