Improvements in Vices.
I, MICHAEL JAEGER, of 15 Liebigstrasse, Darmstadt, in the Empire of
Germany, Merchant, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of my invention is to effect improvements in the construction of bench
and other vices, by mounting the same in such a manner as to enable them to grip
various articles of various forms, in various positions.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar figures
of reference indicate corresponding parts.
Fig. 1 is a longitudinal elevation partly in section of a twin vice constructed
according to my invention.
Fig. 2 is a sectional end elevation of Fig. 1.
Figs. 3 and 8 illustrate the positions to which the jaws may be pivoted when
gripping objects of various forms.
Fig. 4 is a plan view of Fig. 1, partly in section.
Fig. 5 is an elevation, partly in section, showing a modification of my invention.
Fig. 6 is a plan of the same.
Fig. 7 is an elevation, showing the application of my invention to a standard
vice.
The bed plate 1 (Figs. 1, 2, and 4) is secured to a work bench or other article.
2 is a tube or case formed in one with the plate 1. The tube or case 2 is split
on one side and provided with lugs 3, 3, and screws 4, for clamping the tube 5
with its attachments in a vertical or horizontal position, as shown in Fig. 2.
6 is a
pin for further securing the tube 5 in the tube 6, in the position shown, or at right
angles thereto. 7 is one of the back jaws secured to the tube 5 by the screw 8;
9 is another back jaw, secured to the tube 5 by the stud 10 and set screw 11.
12 is one of the front jaws, secured by the screw 13 to the boss of the inner tube 14.
15 is another front jaw, secured to the boss 14 by the stud 16 and set screws 17.
18 is the screw traversing the inner tube 14, and capable of being turned by the
handle bar 19. 20 is the nut in which the screw 18 works. The nut 20 is secured
to the tube 5 by a screw 21. 22 is a slot formed in the tube 14, in which the
neck of the nut 20 works as the tube 14 moves backwards and forwards and which
also serves as a guide to the tube 14. The jaws 9 and 15 are formed for holding
pipes, while cutting screws thereon. The jaws 7, 12, 9 and 15 are movable, and
may be replaced by jaws of other forms than those shown. They are also capable
of partial revolution upon the pins and studs 8, 13, 10 and 16. The twin jaws are
capable of being revolved on their longitudinal axis, as illustrated in Fig. 2.
Figs. 5 and 6 illustrate a modification of my invention, in its application to
parallel vices. 1 is the bed plate. 2 is a rectangular tube or case, formed in one
with the bed plate. The jaw 7 is formed with a segmental base plate or lug 25,
working upon a pivot 8 in a guide 26. The jaw 7 is capable of partial rotation
upon the centre pin 8, the required position being adjusted by one or both of the
set screws 27, 28. The jaw 12 is formed with a pin 13 socketed in the
rectangular slide 14; a set screw 29 or pin 30 being fitted to adjust the position of
the jaw 12.
Fig. 7 illustrates the application of my invention to an ordinary standard bench
vice. The vice is secured to the bench by the bolt 31, nut 32 and screw 33. The
jaw 7 is pivoted to a pin 8, and the jaw 12 is in like manner pivoted to the pin 13;

* 30, 30, for regulating the
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A screw vice, characterised by the arrangement of pivoted jaws 7, 12, secured
to bolts 8 and 13; also jaws 9 and 15 pivoted to pins 10 and 16, all capable of
being held at various angles by means of the bolts 8 and 13, pins 23, 24 and set
screws 11, 17, substantially as herein before described and illustrated by Figs. 1, 2, 3,
and 4 of the drawings.
2. In a screw vice as aforesaid the combination of the jaws 7 and 9, fitted to the
tube 5, and the jaws 12 and 15 fitted to the tube 14, forming a twin screw vice; the
jaws 9 and 15 being formed for holding special objects, such as pipes, while cutting
screws thereon, substantially as herein before described and illustrated by
Figs. 1, 2, 3 and 4 of the drawings.
3. In a screw vice as aforesaid, the combination of the tube 5 fitted in the tube
or case 2, so that the screw vice may be turned upon its longitudinal axis, and secured
in any desired position by clamping the case 2 by means of screws 4, 4; the pin 6
being used to secure the horizontal or vertical position, substantially as herein
before described and illustrated by Figs. 1, 2 and 4 of the drawings.
a
4. In a screw vice as aforesaid, the combination of a back jaw 7, pivoted to a
pin 8; the jaw 7 being formed with a segmental plate or lug 25, working in
groove 26; slide 14, jaw 12 pivoted at 13, set screw 27 and 28, and pin 30, severally
operating substantially as berein before described and illustrated by Figs. 5 and 6
of the drawings.
5. In a screw vice as aforesaid, the combination of a standard fitted with jaws 7:
and 12, pivoted to pins 8 and 13; the said vice being secured to a bench or other
article by means of bolts and screws, substantially as herein before described and
illustrated by Fig. 7 of the drawings.
6. In a screw vice as aforesaid, the combination of movable jaws, capable of
being replaced by others of any required form for special purposes, substantially
as herein before described and illustrated by the drawings.
7. The general construction and arrangement, and the several and respective
combinations of parts, together constituting my invention of improvements in
vices, substantially as herein before described and illustrated by the drawings.
